DETAILED DESCRIPTION
(23)
(24) Here, the hanging bag frame 10 and the hanging bag 1 in
(25) In the present example, the hanging bag 1 is formed from the hanging bag frame 10 and surface elements 36, 38 provided thereon (see
(26) The hanging bag frame 10 in
(27) The covering 40 may include side regions which laterally interconnect the first and second surface elements 36, 38, however, it may also be provided that the conveyed material receiving area 16 is laterally open. In addition, reference is made to the corresponding description in EP 3090967 A2.
(28) Each of the side wall frames 12 and 14 has an upper frame part 12.1, 14.1 and a lower frame part 12.2, 14.2, which may be preferably each formed by bracket elements 12.1b, 14.1b, 12.2b, 14.2b, for example made by bent metal rods.
(29) Unless stated otherwise, the terms upper and lower always refer to the orientation of the hanging bag in the hanging transport position shown, for example, in
(30) A portion of the upper frame part 14.1 of the second side wall frame 14 may be formed as an attachment means 30 for attaching the hanging bag 1 to a guide rail assembly of the suspended conveyor system, wherein for connecting the attachment means to the guide rail assembly a connecting means 50 (trolley) known per se and therefore not described here in more detail may be used, which allows e.g. a rotation of the hanging bag frame 10 about a vertical axis V and about a horizontal axis H (see
(31) The upper and lower frame parts 12.1, 14.2, 12.2, 14.2 are coupled together in a flap connection area 15 by a hinge mechanism 18.
(32) The hinge mechanism 18 comprises two pivot bearings 20, here in the form of two separate pivot bearing components 21, which are provided on opposite side edges 10s of the hanging bag frame 10.
(33) The pivot bearings 20 or in this case the pivot bearing components 21 support the two lower frame parts 12.2, 14.2 in such a way that they are pivotable about a respectively associated pivot axis 12.2a, 14.2a (see
(34) However, it should not be ruled out that, for example, only the lower frame part of the second side wall frame is pivotally supported on the pivot bearings, while the lower frame part of the first side wall frame is arranged rotationally fixed on the pivot bearings, for example when the first side wall does not, as in the example shown, consist of a side wall bracket consisting of two bracket elements with covering but is formed of a rigid plate whose peripheral region forms the first side wall frame.
(35) On each of the pivot bearings 20, a locking element 26 of a locking mechanism 24 is further arranged to be adjustable between a locked position shown in
(36) The two pivot bearings 20 and the two locking elements 26 provided thereon are constructed identically in the present example, so that in the following only one of the pivot bearings 20 with the associated locking element 26 will be described.
(37) In particular, the locking element 26 may be provided on the associated pivot bearing 20 or pivot bearing component 21 to be pivotable about a locking axis 26a indicated by a dashed line in
(38) Structure and function of the hinge mechanism 18, the locking mechanism 24 and the spreading mechanism 28 of the hanging bag 1 according to the exemplary embodiment of
(39) In detail, the sub-figures a) each show a detail enlargement of the area designated by A in
(40)
(41) The locking element 26 is designed to, in the locked position, lock the lower frame parts 12.2, 14.2 of the first and second side wall frames 12, 14 in the closed position, as shown for example in
(42) When the lower frame parts 12.2, 14.2 are in the closed position and the locking element 26 is in the locked position, two claw sections 29 of the locking element 26 partially overlap (reach over) the lower frame part 12.2, 14.2 of the first and second side wall frames 12, 14 in such a manner that they prevent the lower frame parts from being displaced out of the closed position (compare
(43) From the closed position shown in
(44) For this purpose, each of the locking elements 26 may have an actuating section 23 with an actuating surface 23f which preferably slopes downwards and outwards in the locked position. The actuating section 23 may protrude in the locked position on the respective side edge 10s of the hanging bag frame 10 outwardly in the direction of the pivot axes 12.2a, 14.2a from the frame, so that it is easy to grasp, and the slope of the actuating surface 23f allows a downward actuating movement, for example in the direction of the arrow T in
(45) By adjusting the locking elements 26 from the locked position to the release position, the lower frame parts 12.2 and 14.2 are also unfolded from the closed position to the open position by two inclined surface sections 27 provided for this purpose on each locking element 26, wherein the frame parts 12.2, 14.2 can slide along on the inclined surface sections 27.
(46) In this way, when unlocking, at the same time and automatically, an initial downward opening of the hanging bag frame 10 and the hanging bag 1 also takes place, for which only a short action on the actuating surfaces 23f is necessary.
(47) It may namely be provided that a complete opening of the hanging bag 1 downward occurs by the sliding out or falling out of a conveyed material received in the hanging bag and not shown in the figures.
(48) In the present exemplary embodiment, the locking elements 26 can each be biased toward the locked position by a spring 34, for example a leaf spring, which is likewise provided on the associated pivot bearing component 21 by a fastening means 33.
(49) It may happen that the locking elements 26 return to the locked position before the lower frame parts 12.2, 14.2 return to the closed position after emptying of the hanging bag 1 under the influence of their own weight, such as when an emptying due to the size and/or shape of the conveyed material takes a long time.
(50) In order to enable an automatic closing and locking of the hanging bag 1 in this case, it may be provided that the locking elements 26 have further inclined surface sections 39 (cf.,
(51) As can be seen from the sectional views of the sub-
(52) The bearing part 52 of the pivot bearing component 21, which is also shown separately in the sub-figures a), e) and f) of
(53) Between the two lower pivot bearing openings 53, a further passage opening 52o may be located in the bearing part, which serves to receive the fastening means 33 fixing the bearing part 52, the cover part 54 and the spring 34 to each other.
(54) Alternatively or in addition to the fastening with the fastening means, the bearing part 52 and the cover part 54, for example, may be connectable to one another by a latching connection or clip connection, so that they can be assembled purely by hand, i.e. without additional tools.
(55) Furthermore, the bearing part 52 in its upper end region has an L-shaped receptacle 55, in which the bracket of the upper frame part of the first side wall frame can be inserted so that it is connected fixedly to the pivot bearing component 21 after the bearing part 52 has been connected to the cover part 54.
(56) In a central region, the bearing part 52 has a pivot lock opening 58 which, together with the pivot lock insert 56 to be inserted therein, forms a releasable pivot lock 32 for the upper frame part 14.1 of the second side wall frame 14.
(57) This acts similar to the ratchet joint described in EP 3090967. Both the pivot lock opening 58 and the pivot lock insert 56 have a pivot area 58a, 56a and a ratchet area 58b, 56b. The pivot lock insert 56 is vertically slidably received in the pivot lock opening 58 in the assembled state.
(58) The assembly of the pivot lock insert 56 with the inserted upper frame part 14.1 of the second side wall frame 14 on the bearing part 52 is indicated by the dashed arrow between the sub-
(59) In the suspended transport position of the hanging bag 1, the ratchet areas 58b, 56b are, due to the weight of the hanging bag 1, in a positive engagement with one another, which prevents pivoting of the upper frame part 14.1 of the second side wall frame 14 relative to the pivot bearing component 21.
(60) However, by raising the pivot bearing components 21 relative to the upper frame section 14.1 of the second side wall frame 14, the pivot lock insert 56 provided thereon may be displaced in the pivot lock opening 58 such that the ratchet areas 56b, 58b disengage from each other and the pivot lock insert 56 and pivot lock opening 58 abut each other with their respective pivot areas 58a, 56a, which allows a pivoting of the upper frame part 14.1 of the second side wall frame 14 relative to the pivot bearing component 21. In addition, reference is made to the description of the ratchet joint in EP 3090967.
(61) The substantially plate-shaped cover part 54, which is also shown separately in different views in the sub-
(62) The surfaces 52.1 and 54.1 of the bearing part 52 and the cover part 54 facing one another in the assembled state are designed so that the lower frame parts 12.2, 14.2 can be unfolded to a predetermined maximum angle, while the upper frame part 12.1 of the first side wall frame 12 is non-rotatably received by the pivot bearing components 21. Reference is made in particular to the sub-
(63) On the surface 54.2 of the cover part 54, which faces away from the bearing part 52 in the assembled state, a receiving recess 59 for receiving the leaf spring 34 is provided. Finally, the cover part 54 has a further passage opening 54o in the region of the receiving recess 59 for receiving the fastening means 33.
(64) The spring 34, which is again shown separately in a side view and a plan view in the sub-
(65) The locking element 26 is again shown separately in different views in the sub-
(66) The locking element 26 of the hanging bag frame 10 according to the exemplary embodiment may preferably be made in one piece, for example of a plastic material.
(67) In the present exemplary embodiment, the locking element 26 is preferably mirror-symmetrical with respect to the symmetry plane S indicated in
(68) In addition to the already described actuating section 23, the locking element preferably comprises two bracket-receiving sections 66 and a bearing section 68.
(69) Here, the bracket-receiving sections 66 are designed for receiving the bracket elements 12.2b and 14.2b in the closed state of the lower frame parts 12.2, 14.2 and in the locked position of the locking element 26 (see
(70) The bearing section 68 may have two bearing projections 64 with passage openings 64o to receive the locking member 26 on the associated bearing component 21 so that it is pivotable about the locking axis 26a.
(71) On the side of the bearing section 68, which faces the actuating section 23, the two claw sections 29 are formed, which serve as described above, for locking the lower frame parts in the closed position.
(72) In the boundary region between the bracket receiving section 66 and the actuating section 23, the inclined surface sections 27 are provided which form the spreading mechanism 28 of the hanging bag frame 10.
(73) Different contours of the locking element 26 thus fulfil the functions of the locking mechanism 24 and the spreading mechanism 28 in the present preferred exemplary embodiment.
(74)
(75) For features of the further embodiments that correspond to those of the first exemplary embodiment, the same reference numerals are used, and the other embodiments are substantially described only in so far as they differ from the first exemplary embodiment, the above description of which is otherwise explicitly referenced.
(76) As shown in
(77) In order to facilitate the fastening of the covering 40 to the upper frame part 14.1 of the second side wall frame 14, in the second exemplary embodiment the attachment means 30 is formed separately from the bracket element 14.1b of the upper frame part 14.1 of the second side wall frame 14 and fastened by two fastening means 70 at the two upper corners of the upper frame part 14.1. Alternatively, it would also be possible to form the attachment means 30 integrally with the side parts of the upper frame part 14.1 and to connect an additional horizontal transverse strut 14.1x by the two fastening means 70 to the attachment means 30 in order to then fix the covering 40 to the transverse strut 14.1x.
(78) Since the upper frame part 12.1 of the first side wall frame 12 is non-rotatably supported on the pivot bearing components 21 in the second exemplary embodiment just as in the first exemplary embodiment, after releasing the pivot lock, the upper frame part 12.1 and the lower frame part 12.2 of the first side wall frame 12 can be pivoted as a unit and together with the lower frame part 14.2 of the second side wall frame with respect to the upper frame part 14.1 of the second side wall frame attached, for example, to the guide rail assembly to open the conveyed material receiving area 16 upwards.
(79) Alternatively, as illustrated in
(80) In order to allow a defined opening of the hanging bag by up to 180, the pivot bearing components 21 of the second exemplary embodiment are slightly modified from those of the first exemplary embodiment.
(81) In particular, the bearing part 52 of the pivot bearing component 21 shown again separately in sub-
(82) Furthermore, the pivot bearing components 21 of the second exemplary embodiment, in contrast to those of the first exemplary embodiment, comprise an additional, substantially plate-shaped cover member 74, which is shown separately in sub-
(83) The additional cover part 74 can be attached onto the bearing part 52 in such a way that a pin-shaped fastening projection 75 integrally provided on the cover part 74 is inserted into an extension of the lower pivot bearing opening 53 in the stepped projection 71.
(84) In the second exemplary embodiment, in contrast to the first exemplary embodiment, for fastening the individual components to each other, not only one but two passage openings 34o, 54o, 52o are provided in the spring 34, in the cover member 54 and the bearing member 52 respectively, through each of which a fastening means 33 can be inserted.
(85) Also, in the second exemplary embodiment, the passage openings of the cover part and bearing part are not provided in the lower but in the upper region of the respective component, in the case of the bearing member 52 for example at the same height with one end of the L-shaped receptacle 55 for the upper frame part 12.1 of the upper side wall frame (see
(86) One of the passage openings 52o in the bearing part 52 may continue in the step-like projection 71 and serve for fastening the additional cover part 74 by means of an additional fastening means 77, for which a corresponding passage opening 74o may also be provided in the additional cover part 74.
(87) Also, the locking element 26 of the second exemplary embodiment, which is shown in
(88) In particular, three inclined surface sections 27.1, 27.2 and 27.3 with different inclinations are provided for each of the two lower frame parts, allowing a softer initial opening than the inclined surface portions 27 of the first exemplary embodiment which are slightly smaller with respect to surface.
(89) In addition, the further inclined surface portions 39 of the second exemplary embodiment serving for self-locking are also significantly more pronounced than those of the first exemplary embodiment.
(90) The two above-described exemplary embodiments essentially differ in three aspects: (a) in the coupling of the connecting means, (b) in the construction and shape of the pivot bearing components and (c) in the form of the locking element. It is understood that these three aspects are essentially independent of each other, so that the two variants of these three aspects shown can be combined in any desired manner.
(91)
(92) The third exemplary embodiment differs from the previous exemplary embodiments essentially by the configuration of the locking mechanism 24 and the pivot mechanism 28.
(93) First, the general structure will be explained with reference to
(94) The two lower frame parts 12.2 and 14.2 may be similar bracket elements as in the first two exemplary embodiments, which may be provided with a suitable covering, which is not shown here. At the two ends, the lower frame parts 12.2, 14.2, in contrast to the first exemplary embodiments, are in each case fixedly connected to an actuating lever 60.
(95) These actuating levers 60 are formed in the present example as plate-like components having a passage opening 61 for an axle pin 49, which defines in this example the pivot axes 12a, 14a of the two lower frame parts 12.2, 14.2, which coincide here.
(96) With reference to a central axis M indicated in
(97) The control contour 61 is located in a section of the actuating lever 60 which is arranged above the pivot axis 12a, 14a in the hanging transport position of the hanging bag with the lower frame parts 12.2, 14.2 in the closed position (see
(98) The two lower frame parts 12.2, 14.2 are pivotally supported by means of the actuating lever 60 and the axle pin 49 on the pivot bearing 20 shown, which is presently in the form of a pivot bearing component 21 formed in one piece. However, if desired, it could be constructed from a number of composable parts, as in the previously described examples.
(99) In addition to pivot bearing openings 53 for the axle pin 49 and thus for the two lower frame parts 12.2, 14.2, an L-shaped receptacle 55, for example, for the upper frame part (not shown here) of the first side wall frame and another pivot bearing opening 65, for example, for the upper frame part (also not shown) of the second side wall frame, the pivot bearing component 21 may further have three guide openings 42, 43 and 44, which are best seen in the exploded view of
(100) By way of two guide pins 45, 46 which are guided in the guide openings 42, 43 of the pivot bearing 20 and which are fastened to the locking element 26 in openings 2601 and 2602, the locking element 26 is supported on the pivot bearing 20 to be adjustable between the locked position shown in
(101) The upper guide pin 45 defines in this example the pivot axis 26a of the locking element 26. In contrast to the first two exemplary embodiments, however, the pivot axis 26a in the third exemplary embodiment is not stationary with respect to the pivot bearing 20 but is displaceable along a direction Q indicated by a double arrow in
(102) The guide opening 43 extends in a first approximation also in a linear manner and is oriented with respect to the direction Q obliquely along a direction P, and it defines, together with the guide opening 42, the course of the adjusting movement of the locking element 26. It is clear that the shape and course of the guide openings 42, 43 are to be selected such that in these the guide pins 45, 46 can be guided, which are fixedly provided on the locking element 26 and thus have a fixed distance from one another.
(103) Furthermore, in an outwardly laterally facing surface of the locking element 26, an elongated passage opening 47 is provided, through which, at least in the locked position of the locking element 26, a section 48 of the pivot bearing 20 can protrude (see
(104) The locking or unlocking of the hanging bag downwards occurs in the third exemplary embodiment also by pivoting the locking element 26 about the locking axis 26a, whereby claw portions 29 provided on the locking element 26 are brought into engagement or out of engagement with the two lower frame parts 12.2, 14.2, so that they are prevented from being adjusted from the closed position or released.
(105) In contrast to the first two exemplary embodiments, however, the adjustment movement of the locking element 26 in the third exemplary embodiment also comprises a translational movement along the direction Q (see
(106) During this translational movement, an actuating bolt provided on the locking element 26 slides as a spreading actuating element 41 along the control contours 61 of the actuating levers 60, thereby unfolding the lower frame parts 12.2 14.2 away from one another in the manner of a pair of scissors. The spreading actuating element 41 is preferably immovably connected to the locking element 26 and guided in the guide opening 44 along the direction Q.
(107) The course of the opening movement of the lower frame parts 12.2, 14.2 is determined by the course of the control contours 61, among other things. The end stops 61.1 and 61.2 define the end positions of the spreading actuating element 41 and thus of the lower frame parts 12.2, 14.2.
(108) A self-locking of the lower frame parts may be provided in the third exemplary embodiment as well, for example by suitable inclined surface portions of the locking element 26, as described in more detail for the first two exemplary embodiments.
(109) In all exemplary embodiments, the hanging bag can be unlocked and thereby opened by a simple downward actuation of the locking elements 26, which in particular allows automated unloading with a small foot print.
(110) As shown in
(111) In particular, if the pivot axes 12a, 14a do not coincide differently than shown, the lateral sections of the lower frame parts may at least partially overlap one another in the above-mentioned view, preferably in a lower end area.
(112) As shown in
(113) In addition, it is pointed out that the manner indicated in
(114) In particular, the locking and spreading mechanism of the lower frame parts of the third embodiment may be combined with any type of form and bearing of the upper frame parts, in particular with the type described in the first two exemplary embodiments.
(115) The hanging bag according to the invention is, due to the bracket construction, light in weight, is easy and quick to build, and can be used in many ways. In particular, an automated unloading of the hanging bag downward can be implemented in a simple manner and with minimal space requirements.
