Description

[0072] Further advantages, goals, and properties of the present invention will be explained using the following description of exemplary embodiments, which are particularly also shown in the attached drawing. In the drawing, the figures show:

[0073] FIG. 1 schematically, a peeling machine in the region of a peeling head, and an advancing device having an advancing apparatus and an inlet guide;

[0074] FIG. 2 the peeling machine from the preceding FIG. 1, in which the advancing apparatus is separated from the inlet guide, and the inlet guide is separated from the peeling machine gear mechanism;

[0075] FIG. 3 schematically, a view of the inlet guide with wedge clamping elements in the transport direction of a material to be peeled; and

[0076] FIG. 4 schematically, a view of an alternative inlet guide with wedge clamping elements in the transport direction of a material to be peeled.

[0077] The peeling machine 1 shown in FIGS. 1 and 2 has an advancing device 3 in the region of its peeling head 2 with its peeling tools 8.

[0078] Ultimately, in order to then be able to perform a peeling process, the peeling head 2 and therefore also the peeling tools 8 can rotate.

[0079] The advancing device 3 shown in FIGS. 1 and 2 in turn has an advancing apparatus 4 and an inlet guide 5.

[0080] The advancing apparatus 4 and the inlet guide 5 are arranged so as to be displaceable on a traverse 6 of the peeling machine 1, wherein the traverse 6 forms a linear guide 7 for the advancing apparatus 4 and the inlet guide 5. Both the advancing apparatus 4 and the inlet guide 5 can be moved along the linear guide 7 in both directions of the arrows 11 and 12. Therefore, for one thing, the advancing apparatus 4 and the inlet guide 5 can be individually moved away from a peeling machine gear mechanism 13 of the peeling machine 1, or moved toward the peeling machine gear mechanism 13 of the peeling machine 1. For another thing, the advancing apparatus 4 and the inlet guide 5 can be moved relative to one another. This means that the advancing apparatus 4 can also be moved on the traverse 6 independently of the inlet guide 5 and vice versa. It is understood that in deviating embodiments, a different arrangement of advancing apparatus 4 and inlet guide 5 can also be selected here.

[0081] In the operating state of the peeling machine 1 illustrated in FIG. 1, the advancing apparatus 4 and the inlet guide 5 are connected with one another to form a compact advancing device 3, and the advancing device 3 is furthermore connected, together with the inlet guide 5, to the peeling machine gear mechanism 13 of the peeling machine 1. In order for both the advancing apparatus 4 and the inlet guide 5, in particular in the operating state shown, to be reliably connected with the peeling machine gear mechanism 13, for one thing the advancing apparatus 4 and the inlet guide 5 are firmly but releasably wedged into one another by means of first upper wedge clamping elements 14 and 15, as well as by means of lower wedge clamping elements 16 and 17 (see also FIG. 3). For another thing, the inlet guide 5 and the peeling machine gear mechanism 13 are firmly but releasably wedged into one another by means of second upper wedge clamping elements (not explicitly shown here) as well as by means of second lower wedge clamping elements (also not explicitly shown here).

[0082] In this wedged state, a material 22 to be peeled can be precisely guided to the peeling head 2 of the peeling machine 1 and thereby to the rotating peeling tools by means of the advancing apparatus 4, by way of the inlet guide 5. For this purpose, the material 22 to be peeled is guided in the transport direction 24, from an entry region 23, through the peeling machine 1, continuously to an exit region 25, by means of the advancing device 3.

[0083] In the arrangement according to FIG. 2, the advancing apparatus 4 has been displaced to be at a distance from the inlet guide 5, in such a manner that an installation space 26 occurs between the advancing apparatus 4 and the inlet guide 5, which space allows good accessibility not only at the end 27 of the advancing apparatus 4 on the inlet side end, but also at the end 28 of the inlet guide 5 on the advancing apparatus side end. In order to implement the installation space 26, the advancing apparatus 4 is spaced apart from the inlet guide 5 at the distance 29.

[0084] Furthermore, in the case of the arrangement according to FIG. 2, the advancing apparatus 4 and the inlet guide 5 have been displaced away from the peeling machine gear mechanism 13 of the peeling machine 1 to such an extent that a further installation space 30 is made available between the inlet guide 5 and the peeling machine gear mechanism 13. Accordingly, the inlet guide 5 is spaced apart from the peeling machine gear mechanism 13 at a distance 31.

[0085] It is understood that the inlet guide 5 and the advancing apparatus 4 do not necessarily have to be configured to be releasable and displaceable relative to one another in every exemplary embodiment. In particular, these can also be arranged at a fixed distance from one another or in some other way, as long as advancing, on the one hand, and guidance, on the other hand, can be ensured.

[0086] In the present exemplary embodiments, the advancing apparatus 4 has a frame 32 that resists twisting, in which not only the inlet rollers 33 (numbered only as examples here) but also a drive and adjustment mechanism 34 of the inlet rollers 33 are arranged.

[0087] Furthermore, in these exemplary embodiments the inlet guide 5 has a first locking bolt 35 and a second locking bolt 36 (see FIGS. 3 and 4 in this regard).

[0088] In this exemplary embodiment, the peeling machine gear mechanism 13 also has a first and a second locking bolt (not explicitly shown here).

[0089] The first locking bolt 35 of the infeed guide 5 interacts with a complementary locking sleeve 39 in the operating state (see FIG. 1) of the peeling machine 1, and the second locking bolt 36 accordingly interacts with a complementary locking sleeve 40 in the operating state. The locking bolts 35 and 36 ensure that the frame 32 of the advancing apparatus 4 and a twist-resistant box 41 (see FIGS. 3 and 4) of the inlet guide 5 are moved toward one another in guided manner. Furthermore, the twist-resistant frame 32 and the twist-resistant box 41 are additionally mounted in non-rotatable manner relative to one another by means of the locking bolts 35 and 36, in addition to the linear guide 7. By means of the locking bolts 35 and 36, the entire advancing device 3 is held together in significantly more robust and twist-resistant manner. It is understood that in deviating exemplary embodiments, resistance to twisting can also be ensured or guaranteed in sufficient measure in other ways.

[0090] The same also holds true with regard to the locking bolts of the peeling machine gear mechanism 13. These interact with corresponding locking sleeves (not explicitly shown here), which are provided on the inlet guide 5. In the present case, the active connection between the advancing apparatus 4 and the inlet guide 5 will be described in greater detail only as an example. Depending on the concrete embodiment, sufficient guidance and fixation of the modules described above, with one another, can already be achieved merely with two locking bolts and corresponding complementary locking sleeves. It is understood that in the case of further exemplary embodiments, however, more than two locking bolts and locking sleeves can also be used.

[0091] In this exemplary embodiment, the inlet guide 5 additionally also has locking bolts 35 and 36, which pre-fix the advancing apparatus 4 and the inlet guide 5 to one another, independently of the wedge clamping elements 14, 15, 16, and 17.

[0092] A first running shoe 10 and a second running shoe 46 are arranged in the lower region 45 of the twist-resistant box 41 of the inlet guide 5. The inlet guide 5 is connected with the linear guide 7 of the peeling machine 1 in translationally displaceable manner, by way of the two running shoes 10 and 46.

[0093] In this exemplary embodiment, three guide rollers 42 arranged in star shape relative to one another are provided in the twist-resistant box 41 of the inlet guide 5. Each of these guide rollers 42 is carried, in advantageous manner, by a roller carrier 37, which in turn can be individually controlled by means of a guide roller setting element 38, which comprises an actuator motor 43 and a corresponding actuator motor gear mechanism 44 in this exemplary embodiment, so that the material 22 to be peeled, which is supposed to be peeled, can be fed to the peeling head 2 (see FIG. 1) or to the peeling tools 8 with extremely great precision.

[0094] In this regard, the connection between the guide roller setting element 38 or, in this exemplary embodiment, the actuator motor 44, and the corresponding guide roller 42 is sprung by way of a plate spring package 19, so that out-of-roundness or other local deviations in the material 22 to be peeled can be balanced out.

[0095] The plate spring package 19 lies against the roller carrier 37, on the one hand, and against a leveling foot 47, on the other hand, which in turn can be adjusted in the direction toward the material 22 to be peeled or away from it, by means of the corresponding actuator motor gear mechanism 44.

[0096] In the exemplary embodiment shown in FIG. 3, the relative position between the corresponding roller carrier 37, on the one hand, and the leveling foot 47, on the other hand, can be measured by means of a measurement dowel 20 by way of a position measuring device 21, and because of the spring constants of the plate spring package 19, this represents a direct measurement of the force that is in effect between the roller carrier 37 or the guide roller 42 and the leveling foot 47 or the actuator motor gear mechanism 44 and the inlet guide 5. Accordingly, by means of this arrangement, a force sensor 18 is made available, which can measure a force that occurs between the inlet guide 5 and the material 22 to be peeled, or which, together with the other force sensors 18, can measure the forces that occur between the inlet guide 5 and the material 22 to be peeled.

[0097] The structure of the exemplary embodiment according to FIG. 4, in which the force sensor 18 is implemented by means of a force transducer 49, which is arranged in the leveling foot 47 and can directly measure the forces acting on the leveling foot 47 and then output them, deviates slightly from this.

[0098] The force sensors 18 are therefore a component of a measuring device 9 for determining a deviation of the material to be peeled from its required guidance position, since such deviations directly result in a change of the force or forces.

[0099] The measurement results of the measuring device 9 are then used to control the actuator motors 43 accordingly. Depending on the concrete implementation, the measurement results of a corresponding force sensor 18 can be used directly to control the actuator motor 43 that acts on the roller carrier 37 with which the corresponding force sensor 18 is directly connected in active manner. In other implementations, it is also possible to use the measurement results of all the force sensors 18 so as to determine the signals for controlling the actuator motors 43 from their combination with one another, wherein the two possibilities can also be combined or, if applicable, further measurement results can be used supplementally.

[0100] In the present exemplary embodiment, the measured forces are displayed in a visualization 48.

[0101] The dimension with which the individual guide roller setting elements 38 are controlled takes place, in the present case, in a control circuit that comprises the force sensors 18. In the present exemplary embodiment, control takes place by way of delivery of a pulse, wherein the step width of the pulse adjustment can be selected by way of the visualization in this exemplary embodiment. It is understood that in deviating embodiments, it is also possible to waive selectability of the step width or that a different type of control can be selected.
