DETAILED DESCRIPTION

[0064] FIG. 1 is a schematic diagram of a device 1 for processing a particle foam material for producing a particle foam moulded part according to a first embodiment. The device 1 can also be referred to as or considered to be a moulding machine.

[0065] The device 1 is therefore designed for carrying out at least one working process for processing a particle foam material for producing a particle foam moulded part. As is clear from the following, an expansion or connection process of a particle foam material for producing a particle foam moulded part can be considered to be an example of a corresponding working process.

[0066] A particle foam material that can be or is to be processed by means of the device 1 is typically an expandable or expanded plastics particle material. The particle foam material may e.g. be formed by expandable or expanded plastics particles or may comprise expandable or expanded plastics particles. In this context, purely by way of example, reference is made to expanded and/or expandable polypropylene (PP or EPP), expanded and/or expandable polystyrene (PS or EPS) and expanded and/or expandable thermoplastic elastomer (TPE). Mixtures of expandable or expanded particle materials or particles that differ in at least one chemical and/or physical parameter are conceivable; the term “particle foam material” can therefore also cover mixtures of expandable or expanded particle materials or particles that differ in at least one chemical and/or physical parameter.

[0067] The device 1 comprises a die apparatus 2 and a drive apparatus 3 that is or can be assigned to the die apparatus 2. Although it is not shown in the embodiments shown in the drawings, the device 1 may comprise a plurality of die apparatuses 2 and a plurality of drive apparatuses 3.

[0068] In each of the exemplary configurations of the embodiments shown in FIG. 1-3, the die apparatus 2 comprises a first die element 2.1 and an additional or second die element 2.2 in each case. The first die element 2.1 is mounted so as to be movable relative to the additional die element 2.2 along a movement axis A1 defining a movement path and shown by the double-headed arrow P1, which axis is a linear or translational axis. Alternatively or additionally, the additional die element 2.2 could be mounted so as to be movable relative to the first die element 2.1 along the movement axis A1. The die apparatus 2 therefore comprises a plurality of die elements 2.1, 2.2, wherein at least one die element 2.1 is mounted so as to be movable relative to an additional die element 2.2 along a movement axis A1.

[0069] The movably mounted die element 2.1 is mounted so as to be movable between a first position shown in FIG. 1 and an additional or second position shown in FIG. 2. The first position may, as shown in FIG. 1, be correlated with an open position of the die apparatus 2, and the second position may, as shown in FIG. 2, be correlated with a closed position of the die apparatus 2. In the open position of the die apparatus 2, it is possible to access a moulding cavity 4, shown in FIG. 2, of the die apparatus 2. In the closed position, it is not possible to access the moulding cavity 4 of the die apparatus 2. By moving the movably mounted die element 2.1 relative to the additional die element 2.2, an open position and a closed position of the die apparatus 2 can therefore be produced. The die apparatus 2 can therefore be transferred into an open position and a closed position by moving the movably mounted die element 2.1.

[0070] It is conceivable that the movably mounted die element 2.1 and therefore also the die apparatus 2 can be moved into a plurality of open positions, which differ in their respective degrees of opening, and/or into a plurality of closed positions, which differ in their respective degrees of closing.

[0071] If the movably mounted die element 2.1 can be moved into a plurality of closed positions, it is applicable that a first closed position brings about a first degree of closure of the die apparatus 2 and a second closed position brings about a second degree of closure of the die apparatus 2 that is different from, i.e. in particular greater than, the first degree of closure. The movement of the movably mounted die element 2.1 from the first closed position into the second closed position may be an embossing stroke movement, or an embossing stroke for short. In the second closed position, an embossing force can therefore be exerted on a particle foam material positioned in the moulding cavity 4. By moving the movably mounted die element 2.1 from the first closed position into the second closed position, an embossing process can therefore be implemented in which an embossing force can be exerted on a particle foam material positioned in the moulding cavity 4. The second closed position can therefore be referred to as or considered to be an embossing position.

[0072] In the exemplary configurations of the embodiments shown in FIG. 1-3, the die apparatus 2 comprises the movably mounted die element 2.1 and the non-movably mounted additional die element 2.2. The movably mounted die element 2.1 is mounted so as to be movable relative to the additional die element 2.2 between the first position shown in FIG. 1 and the second position shown in FIG. 2. It is clear that the first position is correlated with the open position of the die apparatus 2 and the second position is correlated with the closed position of the die apparatus 2.

[0073] The following information applies by analogy to devices 1 comprising differently configured die apparatuses 2.

[0074] In the exemplary configurations of the embodiments shown in FIG. 1-3, a die element 2.1, 2.2 is designed as a die carrier element, which is designed to carry a die part delimiting the moulding cavity 4 of the die apparatus 2. Alternatively or additionally, a die element 2.1, 2.2 could be designed as a die part delimiting the moulding cavity 4 of the die apparatus 2, in particular a die half delimiting the moulding cavity 4 of the die apparatus 2.

[0075] The drive apparatus 3 is configured for generating and/or transmitting a drive force that sets the movable die element 2.1 into a movement along the movement axis A1. As is clear from the following, the drive apparatus 3 may comprise a plurality of interacting parts for generating and/or transmitting a drive force that sets the movably mounted die element 2.1 into a movement along the movement axis A1.

[0076] The drive apparatus 3 may comprise at least one drive unit 3.1 for generating the drive force and at least one force-transmission unit 3.2 for transmitting a drive force to the movably mounted die element 2.1. The drive unit 3.1 may e.g. be designed as a drive motor, in particular an electric drive motor. The force-transmission unit 3.2 may e.g. be designed as a force-transmission means, in particular force-transmission belts, chains, etc.

[0077] In the exemplary configuration of the embodiment shown in FIGS. 1 and 2, it can be seen that the drive apparatus 3 comprises two force-transmission units 3.2. The drive unit 3.1 is therefore coupled to two force-transmission units 3.2, by means of which a drive force can be transmitted to the movably mounted die element 2.1.

[0078] In all the embodiments, the term “drive force” used herein also covers a “drive torque”; the term “drive force” can therefore be equated with a “drive torque”.

[0079] In the exemplary configurations of the embodiments shown in FIG. 1-3, the drive apparatus 3 comprises a plurality of linear-drive apparatuses 5. The movement axis A1 along which the movably mounted die element 2.1 can be moved is therefore the above-mentioned linear or translational axis. Movements of the movably mounted die element 2.1 along the movement axis A1 are therefore linear or translational movements.

[0080] In the exemplary configurations of the embodiments shown in FIG. 1-3, a relevant linear-drive apparatus 5 comprises a first linear-drive element 5.1 and a second linear-drive element 5.2 interacting therewith, in particular by means of mechanical engagement, which, as is clear from the following, is in particular threaded engagement here. The relevant first linear-drive element 5.1 is mounted so as to be movable along the movement axis A1. The relevant second linear-drive element 5.2 is mounted so as not to be movable along the movement axis A1. The relevant second linear-drive element 5.2 is configured for transmitting a drive force that sets the relevant first linear-drive element 5.1 into a movement along the movement axis A1 to the relevant first linear-drive element 5.1.

[0081] In the exemplary configurations of the embodiments shown in FIG. 1-3, the relevant first linear-drive element 5.1 is designed as a first threaded element, i.e. as a threaded spindle. In the exemplary configurations of the embodiments shown in FIG. 1-3, in each case, the relevant second linear-drive element 5.2 is designed as a second threaded element that is in mechanical engagement with the first threaded element, i.e. in particular as a nut that is in mechanical engagement (threaded engagement) with the threaded spindle. In the exemplary configurations of the embodiments shown in FIG. 1-3, a relevant linear-drive apparatus 5 is therefore designed as a threaded mechanism or screw mechanism comprising a threaded spindle and a nut.

[0082] In the exemplary configurations of the embodiments shown in FIG. 1-3, the respective threaded spindles are mounted translationally along the movement axis A1, but are not rotatably mounted. In the exemplary configurations of the embodiments shown in FIG. 1-3, the respective nuts are mounted so as to be rotatable about a rotational axis, i.e. in particular about the movement axis A1 or an axis of symmetry or a central axis of the nuts, but are not translationally movably mounted. In the exemplary configurations of the embodiments shown in FIG. 1-3, a relevant linear-drive apparatus 5 designed as a threaded mechanism or screw mechanism is therefore configured to have a translationally movable but not rotationally movable threaded spindle and a rotationally movable but not translationally movable nut.

[0083] In the exemplary configurations of the embodiments shown in FIG. 1-3, the drive apparatus 3 comprises a linear-drive apparatus. In the exemplary configurations of the embodiments shown in FIG. 1-3, the drive unit 3.1 associated with the drive apparatus 3 accordingly constitutes a linear-drive unit that is or can be assigned to a relevant first linear-drive element 5.1 or second linear-drive element 5.2. A relevant second linear-drive unit is accordingly configured for generating a drive force that sets the relevant first linear-drive element 5.1 into a movement along the movement axis A1. A relevant linear-drive unit may therefore specifically be designed as a linear-drive motor, in particular an electric linear-drive motor, or may comprise at least one such motor.

[0084] On the basis of the exemplary configurations of the embodiments shown in FIG. 1-3, it can be seen that a linear-drive unit is or can be assigned to a plurality of linear-drive apparatuses 5. A linear-drive unit may therefore be configured for generating a drive force that sets a first linear-drive element 5.1 of a first linear-drive apparatus 5 (cf. e.g. the upper linear-drive apparatus 5 in FIGS. 1 and 2) into a movement along the movement axis A1 and for generating a drive force that sets an additional first linear-drive element 5.1 of an additional linear-drive apparatus (cf. e.g. the lower linear-drive apparatus 5 in FIGS. 1 and 2) into a movement along the movement axis A1. In this way, a synchronous movement of a plurality of first linear-drive elements 5.1 along the movement axis 5 can be produced and/or ensured.

[0085] In the exemplary configurations of the embodiment shown in FIGS. 1 and 2, the linear-drive unit is configured for generating a drive force that sets the respective nuts in a rotational movement. The nuts set into a rotational movement set the respective threaded spindles, which are in mechanical engagement therewith, into a translational movement along the movement axis A1.

[0086] In the exemplary configurations of the embodiments shown in FIG. 1-3, the respective first linear-drive elements 5.1, i.e. the threaded spindles, are coupled, in particular coupled for movement, to the movably mounted die element 2.1. Movements of the respective first linear-drive elements 5.1 therefore correlate with movements of the movably mounted die element 2.1 owing to the coupling or movement coupling to the movably mounted die element 2.1.

[0087] The coupling or movement coupling between the respective first linear-drive elements 5.1 and the movably mounted die element 2.1 may be produced by the respective first linear-drive elements 5.1 being directly or indirectly fastened to the movably mounted die element 2.1; the respective first linear-drive elements 5.1 may therefore be directly or indirectly fastened to the movably mounted die element 2.1. The respective first linear-drive elements 5.1 can be fastened to the movably mounted die element 2.1 by means of form-fitting and/or force-locked and/or material-bonded types of fastening, i.e. by means of clamped fastenings, tensioned fastenings, screwed fastenings or welded fastenings, for example. The respective first linear-drive elements 5.1 can be fastened to the movably mounted die element 2.1 so as to be detachable (without being damaged or destroyed).

[0088] In the exemplary configurations of the embodiments shown in FIG. 1-3, the non-movably die element 2.2 comprises a plurality of, in particular bore-like or bore-shaped, or slot-like or slot-shaped, openings 6, which are or can each be penetrated by a first linear-drive element 5.1. The openings 6 are dimensioned such that there is a certain distance between the walls of the die element 2.2 delimiting said opening and a relevant first linear-drive element 5.1 penetrating said opening, such that the first linear-drive element 5.1 penetrating the relevant opening 6 does not come into contact with the walls of the die element 2.2 delimiting the opening 6. In other words, the openings 6 have a certain oversize compared with a first linear-drive element 5.1 penetrating one of said openings, such that the first linear-drive element 5.1 penetrating the respective openings 6 are mounted so as to be movable relative to the die element 2.2 comprising the openings 6. The openings 6 can therefore be referred to as or considered to be through-openings for corresponding first linear-drive elements 5.1.

[0089] In the exemplary configurations of the embodiments shown in FIG. 1-3, it can be seen that the device 1 may comprise guide apparatuses 7, which are or can be assigned to the linear-drive apparatuses 6 and are configured for guiding, along the movement axis A1, a first linear-drive element 5.1, which is mounted so as to be movable along the movement axis A1, during a movement along the movement axis A1. Movements of the relevant movably mounted first linear-drive element 5.1 may therefore be guided movements. In this way, precise movement and positioning of the mounted die element 2.1 into respective first and second positions or between respective first and second positions can be ensured. Since, in the exemplary configurations of the embodiments shown in FIG. 1-3, the second position is correlated with the closed position of the die apparatus 2, precise positioning of the die element 2.1, 2.2 in the closed position of the die apparatus 2 can therefore also be ensured.

[0090] On the basis of the exemplary configurations of the embodiments shown in FIG. 1-3, it can also be seen that a corresponding guide apparatus 7 may be designed as a linear guide. A corresponding linear guide may comprise a first linear-guide element 7.1 and an additional linear-guide element 7.2. The first linear-guide element 7.1 interacts with the additional linear-guide element 7.2 to form a linear guide of the movably mounted linear-drive element 5.1 along the movement axis A1. The first linear-guide element 7.1 may define a guide axis that coincides with the movement axis A1 or is arranged or oriented in parallel therewith.

[0091] On the basis of FIG. 1-3, it can be seen that the first linear-guide element 7.1 may specifically be designed as a guide rail or guide rod, for example. An additional linear-guide element 7.2 interacting with the first linear-guide element 7.1, this in particular being able to be understood as mechanical engagement here, may be coupled, i.e. in particular coupled for movement, to the movably mounted first linear-drive element 5.1 to be guided. The additional linear-guide element 7.2 may therefore likewise be mounted so as to be movable along the movement axis A1. Specifically, a relevant additional linear-guide element 7.2 may be designed as a guide block, for example.

[0092] On the basis of the exemplary configuration of the embodiment shown in FIGS. 1 and 2, it can be seen that the device 1 may comprise a supporting apparatus 8, which is configured for supporting at least one first linear-drive element 5.1, in particular in an operating position and/or orientation.

[0093] With reference to FIGS. 1 and 2, it is clear that the supporting apparatus 8 may be configured for supporting a plurality of first linear-drive elements 5.1. For this purpose, the supporting apparatus 8 may comprise at least one, in particular crossbeam-like or crossbeam-shaped, supporting element 8.1 that interconnects two first linear-drive elements 5.1, in particular rigidly, to form a support.

[0094] On the basis of the exemplary configuration of the embodiment shown in FIGS. 1 and 2, it can also be seen that the device 1 may comprise a plurality of linear-drive apparatuses 5 arranged or formed in a plurality of spatial planes. As shown by way of example in FIGS. 1 and 2, spatial planes may be understood to be horizontally oriented spatial planes. In principle, arrangements in a plurality of vertically oriented spatial planes or in spatial planes that are oriented at an angle to a horizontal or vertical spatial plane are also conceivable.

[0095] On the basis of the exemplary configuration of the embodiment shown in FIG. 3, it can be seen that the device 1 may comprise two linear-drive apparatuses 5 that are arranged or formed in parallel in a first spatial plane and two linear-drive apparatuses 5 that are arranged or formed in parallel in an additional spatial plane oriented in parallel with the first spatial plane. The device 1 may therefore comprise a first group of two linear-drive apparatuses 5 that are arranged or formed in a first spatial plane (upper or left-hand spatial plane) and an additional group of two linear-drive apparatuses 5 that are arranged or formed in an additional spatial plane (lower or right-hand spatial plane) oriented in parallel with the first spatial plane.

[0096] On the basis of the exemplary configuration of the embodiment shown in FIG. 3, it can also be seen that, in a front view of the die apparatus 3 or a view, shown in FIG. 3, of the main plane of extension of the die element 2.2, polygonal arrangements, i.e. quadrilateral arrangements here, by way of example, of corresponding linear-drive apparatuses 5 or first linear-drive elements 5.1 are possible.

[0097] In this case, it can be seen that the arrangement of the first linear-drive elements 5.1 is selected such that no first linear-drive element 5.1 extends through the moulding cavity 4 of the die apparatus 2.

[0098] Specifically, the exemplary configuration of the embodiment shown in FIG. 3 shows that, proceeding from the exemplary rectangular geometry of a main body (not provided with any further reference signs) of the die element 2.2, it is conceivable for at least one first linear-drive element 5.1 to be arranged in the region of the upper and/or lower and/or lateral edges or in the region of the corners of the rectangular main body of the die element 2.2 in each case. According to the exemplary configuration of the embodiment shown in FIG. 3, a first linear-drive element 5.1 is arranged in each corner of the rectangular main body of the die element 2.2. The respective first linear-drive elements 5.1 can be placed, in particular by a free end, by an end face at the relevant corner of the rectangular main body of the die element 2.2.

[0099] On the basis of the exemplary configurations of the embodiments shown in FIG. 1-3, it can generally be seen that a plurality of first linear-drive elements 5.1 arranged in a particular spatial plane can be arranged in parallel with one another and that respective first linear-drive elements 5.1 arranged or formed in different spatial planes can be arranged in parallel with one another.

[0100] It is applicable to all the embodiments that the device 1 may comprise at least one brake apparatus 9, which is or can be assigned to the linear-drive apparatus 5 and is configured for generating a brake force that brakes a movement of the movably mounted first linear-drive element(s) 5.1 along the movement axis A1 or for generating a blocking force that blocks a movement of the movably mounted first linear-drive elements 5.1. By means of the brake apparatus 9, movements of first or second linear-drive elements 5.1, 5.2 can be braked (to do this, the brake apparatus 9 can generate a brake force that counteracts a movement force acting on a moved first or second linear-drive element 5.1, 5.2 and results in deceleration of the movement of the relevant first or second linear-drive element 5.1, 5.2) or can be completely blocked (to do this, the brake apparatus 9 can generate a blocking force that counteracts a movement force acting on a non-moved first or second linear-drive element 5.1, 5.2 and results in blocking of movements of the relevant first or second linear-drive element 5.1, 5.2).

[0101] A corresponding brake apparatus 9 may in particular be configured for generating an, in particular equal or greater, blocking force that counteracts a force generated as part of a process for processing particle foam material carried out by means of the device 1, in particular a process for expanding particle foam material caused by a pressurised process medium, such as steam. By means of a corresponding brake apparatus 9 or by means of a brake force that can be generated by means of the corresponding brake apparatus 9, the die apparatus 2 can therefore also be secured in the closed position in the operation of the device 1. The corresponding brake apparatus 9 can therefore compensate for the forces acting on the die elements 2.1, 2.2 in the closed position during operation of the device 1, and accordingly the linear-drive apparatuses 5 can therefore be isolated from the forces acting on the die elements 2.1, 2.2 in the closed position during operation of the device 1.

[0102] On the basis of the exemplary configuration of the embodiment shown in FIGS. 1 and 2, it can be seen that a separate brake apparatus 9 may be assigned to each linear-drive apparatus.

[0103] FIG. 4 is a schematic side view of a brake apparatus 9 of a device 1 for processing a particle foam material for producing a particle foam moulded part according to an embodiment.

[0104] In the exemplary configuration of the embodiment shown in FIG. 4, the brake apparatus 9 comprises a brake element 9.1, which can be moved into a braking position, shown by dashed lines in FIG. 4, in which it directly acts on a second linear-drive element 5.2 by forming a brake force or action, and a non-braking position, in which it does not directly act on the second linear-drive element 5.2 by forming a brake force or action. The brake element 9.1 may e.g. be a brake pad or the brake element 9.1 may comprise at least one such brake pad.

[0105] FIG. 5 is a schematic side view of a brake apparatus 9 of a device 1 for processing a particle foam material for producing a particle foam moulded part according to another embodiment.

[0106] In the exemplary configuration of the embodiment shown in FIG. 5, the brake apparatus 9 comprises a brake element 9.1, which can be moved into a braking position, shown by dashed lines in FIG. 5, in which it indirectly acts on a second linear-drive element 5.2 by forming a brake force or action, and a non-braking position, in which it does not indirectly act on the second linear-drive element 5.2 by forming a brake force or action. The brake element 9.1 may again e.g. be a brake pad or the brake element 9.1 may comprise at least one such brake pad.

[0107] In the exemplary configuration of the embodiment shown in FIG. 5, the brake apparatus 9 comprises a brake element 9.1, which can be moved into a braking position, in which it is moved against a component 10 connected to a rotating linear-drive element, i.e. in particular a second linear-drive element 5.2, by forming a brake force or action, and a non-braking position, in which it is not moved against the component 10 connected to the second linear-drive element 5.2 by forming a brake force or action.

[0108] On the basis of FIGS. 4 and 5, it can be seen that, in all the embodiments, the at least one brake element 9.1 can be moved in the movement axis A1 or in parallel with the movement axis; the at least one brake element 9.1 can therefore be movably mounted in the movement axis A1 or in parallel with the movement axis. In principle, however, brake elements 9.1 that are mounted so as to be movable radially relative to the movement axis A1 are also conceivable.

[0109] Even though it is not shown in the drawings, alternatively or additionally, a brake element 9.1 may also directly or indirectly act on the first linear-drive element 5.1. A brake element 9.1 could therefore, for example, directly act on a first linear-drive element 5.1, such that the brake force or action generated by the brake element brakes or blocks a movement of the first linear-drive element 5.1 along the movement axis A1.

[0110] In all the embodiments, the device 1 may comprise a control apparatus 11 implemented with hardware and/or software, which is configured for controlling the operation of the drive apparatus 3 for implementing particular movement or speed profiles of the movably mounted die element 2.1. The control device 11 may in particular be configured for generating control information controlling the operation of the drive apparatus 3. The control apparatus 11 may therefore also be configured for controlling movements of the movably mounted first linear-drive elements 5.1. A corresponding movement or speed profile may e.g. define a particular movement of the movably mounted die element 2.1, in particular starting from the open position into the closed position of the die apparatus 2, and/or a particular movement of the movably mounted die element 2.1, in particular starting from the closed position into the open position of the die apparatus 2.

[0111] The control apparatus 11 may, in particular on the basis of at least one movement or speed profile of the movably mounted die element 2.1, also be configured for controlling the operation of the brake apparatus 9, in particular for implementing particular brake-force profiles. The control device 11 may therefore in particular be configured for generating control information controlling the operation of the brake apparatus 9. The control apparatus 11 may therefore also be configured for controlling movements of a relevant movably mounted brake element 9.1.

[0112] Even though it is not shown in the drawings, the device 1 may further comprise at least one detection apparatus implemented with hardware and/or software, which is configured for detecting movements and/or positioning of the movably mounted die element 2.1 and/or a movably mounted first linear-drive element 5.1. The detection apparatus may comprise at least one, e.g. optically and/or electrically and/or magnetically acting, detection element, which is configured for generating detection information on the basis of movements and/or positioning of the movably mounted die element 2.1 and/or a movably mounted first linear-drive element 5.1. Corresponding detection information can form a basis for the control of the operation of the drive apparatus 3 and/or the brake apparatus 9 that is or can be carried out by means of the control apparatus 11. The detection apparatus can therefore communicate, in particular bidirectionally, with the control apparatus 11, and vice versa.

[0113] Even though it is not shown in the drawings, in all the embodiments, the device 1 typically comprises additional functional apparatuses, which are required for processing particle foam material for producing a particle foam moulded part. For example, these include a steam-generating apparatus for generating steam fed to the die apparatus and/or a steam storage apparatus for storing steam fed to the die apparatus.

[0114] Using the devices 1 shown in the embodiments shown in drawings, a method for processing a particle foam material for producing a particle foam moulded part can be implemented.

[0115] Individual aspects and/or features, multiple aspects and/or features or all the aspects and/or features described in connection with a particular embodiment are transferable to individual aspects and/or features, multiple aspects and/or features or all the aspects and/or features described in connection with at least one other embodiment. The embodiments according to the drawings can therefore be combined with one another.
