Description

Technical Field

[0001] The present invention relates to a cable fixing device for, in particular, releasably fixing a cable, which can be inserted into a cable clamp in an insertion direction into a receiving shaft. The cable clamp comprises a base body, a tensioner arranged on the base body for fixing the cable (in particular, for pressing the cable onto a cable support), and a spring arm, which is supported on the base body and can be moved toward the base body counter to the action of a spring force. The spring arm also comprises a spring-loaded first locking element, which is arranged on a side of the spring arm facing away from the base body.

[0002] The present invention also relates to a control device for controlling at least one drive element of a conveyor device for a sorting system, the control device comprising a housing having a housing base and an interior space. The housing base comprises a rear wall delimiting the interior space. The rear wall also comprises an inner side pointing toward the interior space and an outer side facing away from the interior space. The interior space comprises a wiring area and a control electronics area adjacent to the wiring area. The control device also comprises control electronics and a connection component, the control electronics being arranged in the control electronics area and being connectable to at least one cable via the connection component.

[0003] Finally, the invention relates to a conveyor device and a sorting system having such a control device, as well as the use of such a control device. Background Art

[0004] Cable securing devices are known from the prior art, which can be used to secure a cable between a tensioner and a cable support of a cable clamp. Typically, the tensioner is centrally located on the base of the cable clamp or formed by it, so that the cable is surrounded by the base and held in place. A disadvantage of this is that the cable securing device must be completely released in order to remove the cable. Simply loosening the cable securing device is not sufficient for this purpose. Such a cable securing device is known, for example, from EP 3 093 541 B1.

[0005] In order to prevent the cable clamp from being lost, it is often provided that the cable clamp is constructed integrally with the cable support and / or is connected to the cable support in an articulated manner. Such cable fixing devices are known, for example, from US Pat. No. 7,619,164 B2 and EP 2 492 563 B1.

[0006] The prior art also discloses control devices for controlling drive elements of conveyor systems, which are mounted laterally on the conveyor system. Conventional control devices often have a large overall height in the depth direction to improve accessibility when wiring cables. This results in a particularly large space requirement in the width direction when assembled. Summary of the Invention

[0007] The object of the present invention is to provide an improved cable fixing device, in particular to enable simple operation of the cable fixing device.

[0008] Another object of the present invention is to provide an improved control device, in particular to improve the accessibility of the connections for the cables and / or to minimize the space required.

[0009] Furthermore, the object of the present invention is to specify an improved conveying device, an improved sorting system and a use for such a control device.

[0010] The first task is achieved by a cable fixing device of the type mentioned at the beginning of the article, wherein the clamp is arranged laterally, in particular integrally formed on the base body and in particular has an exposed first side and a second side opposite to the first side, the base body and the spring arm are preferably completely arranged on the second side of the clamp.

[0011] The advantages achieved by the present invention are particularly that the base is only provided on one side of the cable to be secured, and thus the cable to be secured is not surrounded by the cable securing device. This allows, on the one hand, the cable securing device to be implemented with a particularly small space requirement, in particular with a small width. On the other hand, lateral removal of the cable is possible, so that the cable clamp need not be completely pulled out of the receiving shaft, but only needs to be loosened. This also improves the operability of the cable securing and reduces the risk of losing the cable clamp. In particular, the cable clamp can be operated with one hand.

[0012] The base body preferably has a first side surface on which the hold-down device is arranged. Furthermore, the base body may have a second side surface, different from the first side surface, on which the spring arm is arranged. Particularly preferably, the first side surface and the second side surface (in particular, opposite sides of the base body) are arranged parallel to each other or at a right angle.

[0013] The cable clamp extends in the longitudinal direction between an insertion end, with which the cable clamp is inserted (facing forward) into the receiving shaft, and an actuating end, which preferably remains outside the receiving shaft so that the cable clamp can also be removed from the receiving shaft.

[0014] In order to improve the operability of the cable clamp, provision can be made for an operating element, in particular a grooved surface, to be arranged on the spring arm and / or the base body. The operating element is preferably arranged on the operating end.

[0015] Furthermore, it is preferably provided that the cable clamp is produced in one piece, in particular in an injection molding process.

[0016] The first locking element can cooperate with the second locking element of the receiving well to fix the cable clamp in the receiving well in a fixed position. In the fixed position, the cable clamp is positioned in the receiving well such that the cable is clamped between the hold-down device and the cable support.

[0017] Advantageously, the cable securing device includes a cable support, which is arranged, for example, adjacent to the receiving shaft, in particular adjacent to the receiving shaft, so that the cable can be secured by clamping between the hold-down device and the cable support. The cable support can, for example, be integrally formed with the receiving shaft. To this end, the cable support can, for example, be arranged on the outer side of the shaft wall of the receiving shaft, in particular, be integrally formed thereon.

[0018] Advantageously, the first locking element can be moved from a locked position into a disengaged position by moving the spring arm toward the base body, in particular against the action of a spring force. In the locked position, the first locking element cooperates with a second locking element of the receiving shaft, and in the disengaged position, the first locking element can be moved past the second locking element against the insertion direction. In the disengaged position, the first and second locking elements no longer cooperate. As a result, the cable clamp can be pulled out of the receiving shaft.

[0019] Advantageously, the base body and the spring arm are arranged at a distance relative to each other, the distance being variable against the action of a spring force, and the first locking element being in the engaged position when the distance corresponds to a first distance, and in the disengaged position when the distance corresponds to a second distance, the first distance being greater than the second distance.

[0020] It is particularly preferred to provide that: the base body and the spring arm form an opening angle that can be changed against the action of the spring force, when the opening angle corresponds to a first opening angle, the first locking element is in the engaged position, and when the opening angle corresponds to a second opening angle, the first locking element is in the disengaged position, the first opening angle being greater than the second opening angle.

[0021] To prevent the cable clamp from being accidentally pulled out of the receiving well, it is preferably provided that the cable clamp has a loss prevention feature, which includes a stop element that cooperates with a stop element of the receiving well to limit the adjustment displacement of the cable clamp counter to the insertion direction, in particular within the receiving well. To this end, it can be provided that the receiving well includes a stop element. This stop element can be provided, for example, by the second locking element.

[0022] The stop element is preferably arranged such that the adjustment path is greater than the cable diameter, in particular, greater than the maximum cable diameter of the cable to be secured. To this end, the cable clamp can be arranged at a distance from the clamp, in particular, from the contact surface of the clamp, in the longitudinal direction of the cable clamp. Advantageously, the distance between the stop element and the clamp, in particular, the contact surface, corresponds to at least 40%, in particular, 50% to 75%, of the total length of the base body of the cable clamp. Particularly preferably, the distance between the clamp and the stop element is greater than the cable diameter, preferably at least 0.5 cm, and particularly preferably at least 1 cm.

[0023] Preferably, the locking element and the stop element are positioned at a distance from each other along the longitudinal direction of the cable clamp. Preferably, the distance between the insertion end and the stop element along the longitudinal direction of the cable clamp is smaller than the distance between the insertion end and the locking element.

[0024] Advantageously, the stop element is arranged on the base body and / or the spring arm, in particular on the side of the spring arm facing away from the base body. Preferably, the stop element is configured as a protrusion, in particular a semicircular protrusion, arranged on the base body and / or the spring arm.

[0025] Preferably, the stop element is movable from a locked position, in which it cooperates with the stop element, into a released position, in which it can be moved past the stop element counter to the insertion direction. This ensures that, on the one hand, the stop element engages behind a stop element, in particular the second locking element, of the receiving well in the locked position, thereby limiting the removal movement counter to the insertion direction via the projection. This prevents the cable clamp from being unintentionally pulled out of the receiving well. On the other hand, in the released position, the stop element does not engage behind the stop element, in particular the second locking element, so that the cable clamp can be completely removed from the receiving well.

[0026] When the stop element is arranged on the base body and / or the spring arm, the stop element can be moved from the locking position to the release position by relative movement between the base body and the spring arm, in particular by movement of the spring arm toward the base body.

[0027] It is advantageously provided that: when the opening angle corresponds to the first opening angle, the stop element is in a first locked position, when the opening angle corresponds to the second opening angle, the stop element is in a second locked position, and when the opening angle corresponds to a third opening angle which is smaller than the second opening angle, the stop element is preferably in a released position.

[0028] Advantageously, the cable fixing device further comprises the receiving well into which the cable clamp can be inserted. The receiving well preferably has an insertion opening and a second locking element, preferably a locking projection, particularly arranged on the inner wall of the receiving well. When the cable clamp is in the fixed position in the receiving well, the first locking element and the second locking element cooperate to limit a pull-out movement counter to the insertion direction.

[0029] The receiving shaft is preferably dimensioned and / or designed in the longitudinal direction such that the first locking element can be completely introduced into the receiving shaft, in particular such that the first locking element engages the second locking element from behind. To this end, the total length of the receiving shaft can be greater than the longitudinal distance between the insertion end and the end of the first locking element facing away from the insertion end in the longitudinal direction of the cable clamp. Alternatively or additionally, the receiving shaft can be designed to be open at both ends.

[0030] Advantageously, when the cable clamp is inserted into the receiving well, the first locking element is pretensioned toward the inner wall of the receiving well by a spring force, preferably applied by the spring arm or a spring element operatively connected to the spring arm.

[0031] The receiving shaft preferably has four circumferentially arranged shaft walls, which delimit the shaft interior and provide the inner wall. The second locking element is preferably integrally formed on one of the shaft walls in a manner that protrudes into the shaft interior.

[0032] Advantageously, the first locking element has a plurality of locking projections arranged one after the other in the longitudinal direction of the spring arm. This allows the cable clamp to be fixed in the receiving shaft at different insertion depths, and thus the cable fixing device can be adapted to different cable diameters. Particularly preferably, the locking projections each extend orthogonally to the longitudinal direction of the spring arm.

[0033] The different insertion depths correspond to respective securing positions for cables with specific cable diameters. The first locking element can, for example, have three locking projections, and at a first insertion depth, only the first of the locking projections engages behind the second locking element to secure the cable clamp in the first securing position. At a second insertion depth, the second of the locking projections engages behind the second locking element to secure the cable clamp in the second securing position. Furthermore, at a third insertion depth, the third of the locking projections engages behind the second locking element to secure the cable clamp in the third securing position.

[0034] Advantageously, the hold-down device is designed to press the cable to be fixed downwards in the insertion direction, in particular downwards against the cable support. For this purpose, the hold-down device preferably has a contact surface that can be positioned on the cable to be fixed.

[0035] It is advantageous if the hold-down device is designed to be flexible, in particular elastically deformable.

[0036] Furthermore, it can be provided that friction-increasing means, preferably an anti-slip coating and / or a plurality of, in particular, serrated projections, are provided on the clamp, for example on the clamping surface that can be positioned on the cable, thereby improving the fixing of the cable, in particular in the longitudinal direction of the cable.

[0037] Furthermore, it is advantageous if a first guide element is provided on the base body, which cooperates with a second guide element provided on the inner wall of the receiving well to guide the base body in the insertion direction. The first guide element can, for example, be configured as a projection extending in the longitudinal direction of the base body, in particular, integrally formed on the base body. Similarly, the second guide element can be configured as a projection extending in the longitudinal direction of the receiving well, in particular, provided (preferably integrally formed) on the inner wall of the receiving well.

[0038] It is preferably provided that the cable fixing device (as described above) includes a cable support for accommodating the cable to be fixed. Furthermore, the cable fixing device can include an electrically conductive insert element, which is positioned on the cable support. Particularly preferably, the electrically conductive insert element can be grounded, for example by being electrically connected to a rear wall and / or a metal plate of the control device described below. This avoids the need for an additional shielding layer and further simplifies the handling of the cable fixing device. For this purpose, the insert element can be fixed to the cable support, for example, by means of electrically conductive fixing elements, such as electrically conductive rivets, screws, electrically conductive adhesive, or the like, which are or can be grounded.

[0039] A further object is achieved, utilizing the advantages and effects described above, by a control device of the type mentioned initially, which comprises a cable holder which is arranged in the connection area and is designed according to one of the aspects described above.

[0040] The advantages achieved by the present invention are, in particular, that cables connected to the control electronics of the control device can be secured in the connection area in a simple and particularly space-saving manner. The cables can be placed laterally onto a cable guide or cable holder and secured in the insertion direction by squeezing the cable clamp. The cable clamp can be operated with one hand. The cable securing device requires particularly little space in the width direction, allowing multiple cables to be routed side by side to the control electronics in a particularly space-saving manner.

[0041] Furthermore, the cable fixing device relieves the cable of tensile forces, so that the cable can be guided essentially laterally out of the interior of the control device.

[0042] The structural height of the control device is understood to be the distance between the rear wall and the highest point of the control device in the depth direction. The depth direction is oriented orthogonally to the rear wall.

[0043] The aforementioned receiving shaft and / or the cable support can be arranged in the connection area so as to protrude from the rear wall in the depth direction. Particularly preferably, the receiving shaft and / or the cable support are constructed integrally with the base body.

[0044] Furthermore, another object is achieved by a control device of the type mentioned at the outset, in which the housing base comprises a connection wall which delimits the connection area and protrudes from the rear wall in the depth direction, and the connection wall has a plurality of through-openings for cables and is configured on an outer side facing away from the connection area with a plurality of guide surfaces for guiding the cables, each of the guide surfaces being adjacent to a through-opening and being configured at least partially convex, preferably in an inversely curved manner.

[0045] The advantages achieved by the present invention are, in particular, that the cables can be guided laterally out of the control device and, via the convex section of the guide surface, in the direction of the rear wall plane located in the rear wall. If the control device is mounted, for example, with the rear wall, on a frame profile of a conveyor system, the cables can be guided via the guide surface to the frame profile, so that the control device can be realized with a low overall height and thus can be arranged particularly flat on the frame profile.

[0046] Advantageously, the guide surface comprises a convex section adjoining the through-opening, whereby the cable can be guided along the convex section in the direction of the rear wall.

[0047] Furthermore, the guide surface can include a concave section adjoining the convex section, so that the guide surface is essentially anti-curved. Along the concave section, the cable is bent in a further direction, so that the cable can be guided essentially parallel to the frame profile or parallel to the rear wall, away from the control device.

[0048] In addition, another object is solved by using a control device of the type mentioned at the beginning of the article, wherein the control electronic device includes a first circuit board and a second circuit board, a control circuit is respectively arranged on the first circuit board and the second circuit board, and the first circuit board and the second circuit board are arranged one above the other (stacked) in the control electronic device area of the housing, and the connecting component includes a first connecting unit arranged on the first circuit board facing the wiring area and can be connected to at least one first cable, and a second connecting unit arranged on the second circuit board facing the wiring area and can be connected to at least one second cable, the second circuit board is constructed to be smaller than the first circuit board in at least one extension direction and is arranged in the housing in such a way that the first connecting unit and the second connecting unit are arranged offset relative to each other in the wiring direction.

[0049] The advantage achieved thereby is, in particular, that the cables can be connected to the control electronics essentially laterally, thereby also enabling a particularly low overall height of the control device to be achieved.

[0050] The offset arrangement of the connecting units also results in improved accessibility to the connecting units, so that the cables can be connected in a simple manner during assembly of the control device.

The wiring direction preferably extends perpendicularly to the edge toward the opposite edge. Another first and second connecting units of the connecting assembly can be disposed on the opposite edges of the corresponding printed circuit board in a similar manner.

Particularly preferably, the connection units include, for example, a CAN bus connector, an Industrial Ethernet (Profinet) connector, an Ethernet connector, and / or a power connector.

[0055] When the control device is mounted on a conveyor system, it is possible that the first connection unit provided on the first circuit board is more accessible and illuminated than the second connection unit provided on the second circuit board. Therefore, it is preferably provided that the first connection unit includes a small and / or difficult-to-operate connector and the second connection unit includes a large and / or easy-to-operate connector.

[0056] Furthermore, it is advantageous if the first connecting unit and / or the second connecting unit protrudes into the connection region.

[0057] Furthermore, the connection module is preferably arranged such that the connection direction, along which cables and connectors can be connected, for example, is oriented parallel to the first printed circuit board and / or the second printed circuit board.

[0058] In order to achieve a particularly compact design, in particular a particularly low overall height, it is preferably provided that the first printed circuit board and the second printed circuit board are oriented parallel to one another and preferably parallel to the rear wall of the housing.

[0059] As described above, it can be provided that the connection wall has a plurality of guide surfaces for guiding cables on its outer side. Advantageously, some of the guide surfaces form a first group and some of the guide surfaces form a second group, with the guide surfaces of the first group adjoining the respective through-openings at a first perpendicular distance from the rear wall, and the guide surfaces of the second group adjoining the respective through-openings at a second perpendicular distance from the rear wall. This allows cables intended for the first circuit board and cables intended for the second circuit board to be guided into the connection area at corresponding heights. In particular, it is provided that the second perpendicular distance is greater than the first perpendicular distance.

[0060] Particularly preferably, the guide surfaces of the first group are assigned to the first connecting unit, and the guide surfaces of the second group are assigned to the second connecting unit.

[0062] The through-opening is preferably designed as a slit that is open toward an edge of the connection wall, in particular toward an upper edge of the connection wall facing away from the rear wall, so that the cable can be inserted into the corresponding slit via the open side. The sealing element can also have a slit that is open toward an edge, into which the cable can be inserted. It is preferably provided that the sealing element is shaped like a comb and is inserted into the slit along the open edge of the connection wall.

[0063] Alternatively or additionally, the connection wall can be double-walled with a gap. The sealing element can, in particular, be at least partially disposed in the gap. It is preferably provided that the gap of the sealing element and the through-opening are aligned with one another. Alternatively, multiple sealing elements can be provided, each of which is disposed in a respective through-opening.

[0064] Advantageously, a plurality of guide elements, preferably guide brackets, adapted in particular to the cable diameter, are provided on the outside of the connection wall in order to guide, in particular fix, the cables along the guide surface.

[0066] Furthermore, the housing, in particular the housing base, preferably has a partition wall protruding from the rear wall in the depth direction, which separates the wiring area from the control electronics area and has a plurality of connection openings for the connection component, which connect the wiring area to the control electronics area.

[0067] Advantageously, the cable can be guided through the connection opening to a connection unit, in particular a connector, of the connection assembly, or a connection unit, in particular a connector, of the connection assembly is oriented on, arranged in and / or guided through the connection opening.

[0068] Furthermore, it is advantageous if the partition wall includes a first partition wall section protruding from the rear wall in the depth direction, a second partition wall section extending in the depth direction and arranged offset relative to the first partition wall section in the wiring direction, and a third partition wall section connecting the first and second partition wall sections, at least one of the connecting openings being arranged in the first partition wall section, and at least one of the connecting openings being arranged in the second partition wall section. Thus, the partition wall is constructed in a substantially stepped manner and can be adapted to different sizes of the circuit boards and / or to the offset positioning of the connecting units.

[0069] The first connection unit is preferably oriented on the first connection opening, arranged on the first connection opening, and / or guided through the first connection opening. Optionally, the first connection unit protrudes into the wiring area. Furthermore, it is advantageous if the second connection unit is oriented on the second connection opening, arranged in the second connection opening, and / or guided through the second connection opening. This allows the connection between the cable and the control electronics to be established via the corresponding connection opening. Optionally, the first connection unit and / or the second connection unit protrude into the wiring area.

[0070] In order to make the connection area accessible for connecting cables, it is preferably provided that the housing has a locking flap that is mounted on the housing base body so as to be movable, in particular pivotable, between an open position, in which the connection area is accessible, and a closed position, in which the connection area is closed.

[0108] First, it should be noted that identical components are provided with identical reference numerals or component names in the various embodiments described, and that the disclosure contained throughout the entire description can be transferred to identical components having identical reference numerals or component names. Positional designations selected in the description, such as "upper," "lower," "lateral," etc., also refer to the directly described and illustrated figures, and these positional designations are transferred to the new position in the event of a change in position.

[0109] exist Figure 1 1 shows a perspective view of a cable fixing device 1 comprising a cable clamp 2. The cable clamp 2 extends in the longitudinal direction from an operating end HE to an insertion end EE and can be inserted in the insertion direction substantially with the insertion end EE forward. Figure 2 For this purpose, the cable clamp 2 can be actuated at the actuating end HE, essentially between two fingers.

[0110] As in Figure 1 As can be seen in FIG, the cable clamp 2 comprises a base 21 and a presser 22 provided on the base 21 for pressing the cable K downward in the insertion direction, as shown in FIG. Figure 3c and Figure 3d in and Figure 4a Shown in.

[0111] The cable clamp 2 also has a spring arm 23 supported on the base 21. The spring arm 23 can be moved against the action of a spring force toward the base 21 in order to tension the base. To this end, the cable clamp 2 can be compressed at the operating end HE, in particular, the spring arm 23 can be pressed toward the base 21. The spring arm 23 and the base 21 preferably form an opening angle α, which can be varied by moving the spring arm 23 toward the base 21. Preferably, the spring arm 23 and the base 21 are designed such that the cable clamp 2 is essentially V-shaped.

[0112] In order to fix the cable clamp 2 in the receiving shaft 3, the cable clamp comprises a first spring-loaded locking element 24. The locking element is arranged on the spring arm 23 for this purpose. Figure 1As can be seen in FIG, the first locking element 24 can have a plurality of locking projections in order to fix the cable clamp 2 in the receiving shaft 3 at different insertion depths. Figure 3c and Figure 3d In the embodiment, the cable clamp 2 is arranged and fixed in the receiving shaft 3 at two different insertion depths.

[0113] Furthermore, the cable clamp 2 may have an optional anti-lost portion comprising a stop element 25. The stop element 25 may be arranged on the base body 21 at a distance from the first locking element 24 in the longitudinal direction of the cable clamp 2 or as in Figure 1 As shown in FIG, the stop element 25 is arranged on the spring arm 23. The stop element 25 can cooperate with a stop element of the receiving well 3 in order to prevent the cable clamp 2 from being pulled out unintentionally from the receiving well.

[0114] In order to improve operability, the cable clamp 2 can comprise an operating element 26 arranged on the operating end HE, in particular the spring arm 23. The operating element 26 can be designed as a grooved surface of the spring arm 23, for example.

[0115] exist Figure 2 The receiving shaft 3 is shown in a cross section. The receiving shaft 3 is open at a first end so that the cable clamp 2 can be inserted into the receiving shaft 3 in the insertion direction. At the second end opposite the first end in the insertion direction, the receiving shaft 3 can also be open or closed. Figure 2 It is constructed in a closed manner as shown in FIG.

[0116] The longitudinal dimension of the receiving shaft 3 preferably corresponds at least to the longitudinal distance d between the insertion end EE of the cable clamp 2 and the end of the first locking element 24 facing away from the insertion end EE, so that the first locking element 24 can be completely introduced into the receiving shaft 3 .

[0117] The receiving shaft 3 comprises a second locking element 34, which is arranged in the interior of the receiving shaft 3, preferably on the inner wall formed by the shaft wall 31 of the receiving shaft 3. The second locking element 34 can be arranged on a first end of the receiving shaft 3, for example.

[0118] The receiving shaft 3 can further comprise the previously described stop element which interacts with the stop element 25 and is preferably formed by a second locking element 34 .

[0119] exist Figures 3a to 3d The insertion of the cable clamp 2 into the receiving shaft 3 is shown in cross section.

[0120] In this case, the cable clamp 2 is introduced with the insertion end EE into the receiving shaft 3 and inserted into the receiving shaft 3 by a movement in the insertion direction, in particular by pressing the insertion end downwards.

[0121] As in Figure 3b As can be seen in FIG, the stop element 25 is first moved past the second locking element 34. Here, the stop element 25 is in a first locking position or a second locking position, in which it engages behind the second locking element 34. In order to pull the cable clamp 2 out of the receiving shaft 3, it can be compressed, in particular by reducing the opening angle α, so that the stop element 25 is brought into a release position, in which it can be moved past the second locking element 34.

[0122] In order to fix the cable K, the cable clamp 2 can be arranged in the receiving shaft 3 in a fixed position, such as in Figure 3c and Figure 3d For example, to fix a cable K having a first cable diameter, the cable clamp 2 can be arranged at Figure 3c In the first fixing position shown in FIG, the cable clamp 2 is locked in the second locking element 34 at a first insertion depth with its first locking element 24, in particular with the first locking projection of the first locking element 24. In addition, the cable clamp 2 can be arranged Figure 3d In the second fixing position shown in FIG, the cable clamp 2 is locked in the second locking element 34 at a second insertion depth with its first locking element 24, in particular with the second locking projection of the first locking element 24, in order to fix a cable K having a second cable diameter. In the example shown, the second cable diameter is smaller than the first cable diameter. The cable K is Figure 3c and Figure 3d Indicated by dotted line.

[0123] exist Figure 4a and Figure 4b 1 shows a greatly simplified front view of the cable fixing device 1. The cable fixing device 1 can comprise an optional cable support 32, on which the cable K is placed and against which the cable K can be pressed by means of a presser 22 in order to fix the cable K.

[0124] In the example shown, the cable clamp 2 is Figure 4a In the fixed position, the cable K is fixed between the tensioner 22 and the cable support 32. Figure 3c or Figure 3d The arrangement structure shown in .

[0125] exist Figure 4b In the embodiment, the cable clamp 2 is arranged in a release position, in which the cable K (as indicated by the curved arrow) can be removed laterally. This essentially corresponds to the Figure 3b The arrangement structure shown in .

[0126] Figure 5 Two cable fixing devices 1 arranged side by side are shown, which are constructed essentially identically, in particular mirror-symmetrically, and each include a cable clamp 2 and a receiving shaft 3. The cable fixing device 1 includes an insertion element 33, which is arranged on a cable support 32. The insertion element 33 is preferably made of an electrically conductive material and is grounded. To this end, the insertion element can be fixed to the cable support 32, for example, via screws or rivets. In the example shown, the cable fixing devices arranged side by side have a common insertion element 33. Alternatively, it can be provided that there is only one cable fixing device 1 with an insertion element 33. Similarly, it can be provided that two cable fixing devices 1 arranged side by side each have an insertion element 33.

[0127] exist Figure 6 The cable fixing device 1 is shown in FIG. Figure 3d , a cross-sectional view in plane VI, indicated by a dashed line, is shown in FIG. As can be seen in this cross-sectional view, the cable clamp 2 can include a first guide element 27, which is arranged on the base body 21, in particular, integrally formed therewith. Furthermore, the receiving shaft 3 can include a second guide element 37 that cooperates with the first guide element 27 and is arranged, for example, integrally formed, on the inside of the receiving shaft 3, in particular, on the shaft wall 31 thereof. The cooperating guide elements 27, 37 allow the cable clamp 2 to be guided in the insertion direction within the receiving shaft 3.

[0128] Figure 7a A perspective view of a control device 4 for actuating at least one drive element of a conveyor device 9 for a sorting system 100 is shown. Figure 7b In FIG, the control device 4 is shown in a cross-sectional view.

[0129] The control device 4 comprises a housing with an interior space which can be divided into a control electronics area SB and a connection area AB. The housing can have a cover 58 which covers the control electronics area SB.

[0130] Furthermore, the housing has a housing base 5 with a rear wall 51 that delimits the interior space, in particular in a depth direction TR. Here, the depth direction TR is oriented orthogonally to the rear wall 51. A cover 58 for the control electronics area SB is preferably arranged parallel to the rear wall 51 and spaced apart therefrom in the depth direction TR.

[0131] Furthermore, the housing base 5 may include a connection wall 52a protruding from the rear wall 51 in the depth direction TR, which laterally closes the connection area AB. A plurality of through openings 53 are preferably provided in the connection wall 52a, through which the cables K can be guided from the outside into the connection area AB, as shown in FIG. Figure 10a and Figure 10b As shown in .

[0132] On the outer side of the connection wall 52a facing away from the connection area AB, the connection wall can be configured with a plurality of guide surfaces 55 adjoining the through-opening 53. The guide surfaces 55 are preferably configured at least partially convex so that the cable K can be guided as in Figure 10a 5. In order to also lead the cable K out essentially parallel to the rear wall 51, it can be provided that the guide surface 55 has a concave section adjoining the convex section and is thus designed in an anti-curved manner.

[0133] Furthermore, a plurality of arcuate guide elements 56 are preferably provided on each guide surface 55 , said guide elements being shaped such that the cable K can be accommodated between the guide surface 55 and the guide elements 56 .

[0134] Furthermore, the housing can have a partition wall 52 b protruding from the rear wall 51 in the depth direction TR, which partition wall separates the control electronics area SB and the wiring area AB from one another. Here, the partition wall 52 b can be produced in one piece with the housing base body 5 , for example.

[0135] Alternatively, the partition wall 52b can be manufactured in one piece with the cover 58 and connected to the cover, for example, via a film hinge. The partition wall 52b can, for example, include a locking projection that cooperates with a locking receptacle in the rear wall 51 to connect the partition wall 52b to the rear wall 51.

[0136] Furthermore, it can be provided that the housing base 5 comprises two side walls 52c extending parallel to one another and oriented orthogonally to the connecting wall 52a. Thus, it can be provided that the rear wall 51, the connecting wall 52a and the side walls 52c delimit the interior space.

[0137] In order to dissipate heat from the control device 4 , the housing can include a metal plate 57 which is arranged on the outer side of the rear wall 51 .

[0138] Furthermore, it is preferably provided that the control device 4 comprises one or more cable fixing devices 1 which are arranged in the connection area AB. These cable fixing devices 1 can be arranged as in the example of Figures 1 to 4b The receiving shaft 3 and / or the cable mount 32 can be formed integrally with the housing main body 5 and / or protrude from the rear wall 51 in the depth direction TR.

[0139] In order to cover the connection area AB in an openable manner, the housing preferably comprises a locking flap 6 supported on the housing base 5. In the example shown, on the one hand Figure 7a and Figure 7bThe first connection area AB shown on the left in FIG is accessible via the opened locking flap 6 and on the other hand Figure 7a and Figure 7b The second connection area AB shown on the right in the middle is covered by the closed locking flap 6. Thus, the locking flap 6 shown on the left is in the open position, and the locking flap 6 shown on the right is in the closed position.

[0140] The housing may also include one or more optional screw caps 59 protruding from the rear wall. These screw caps are positioned so that the locking flap 6 can be secured in the locked position by screwing. To this end, the locking flap 6 may have corresponding holes or hole markings for receiving these holes. When the locking flap 6 is in the locked position, the holes or hole markings are aligned with the screw caps 59. Thus, screws can be screwed into the screw caps 59 through the holes to secure the locking flap 6 in the locked position. This ensures that the locking flap 6 cannot be opened without tools.

[0141] Furthermore, the locking flap 6 preferably includes side parts 66 and a recess, in particular a U-shaped recess, open toward the edge of the locking flap 6 and lockable by the removable and / or pluggable side parts 66. The recess is opened by removing the side parts 66 so that, for example, when the control device 4 is mounted on a wall, a cable K can be guided laterally out of the housing through the recess. After removal, the side parts 66 can preferably be stored in or on the cover. To this end, the cover can have a receptacle for the side parts 66 on its inner side so that the side parts 66 cannot be lost.

[0142] If also from Figure 7a and Figure 7b As a result, the housing can be constructed essentially in a mirror-symmetrical manner, with the interior space having a centrally located control electronics area SB and a connection area AB laterally adjoining the control electronics area. The connection areas AB are preferably constructed essentially identically. The interior space is bounded by a rear wall 51, two mutually opposing connection walls, and side walls 52c.

[0143] exist Figure 8 The locking flap 6 is shown in FIG. Figure 7b Detailed view of area VIII indicated by dashed lines in FIG. The locking flap 6 is pivotally mounted on the housing base 5 via a hinge, in particular between the housing base 5 and the cover 58. To this end, the locking flap 6 has a hinge pin 61, and the housing base 5 and / or the cover 58 have a pin receptacle 62 in which the hinge pin 61 is mounted. Preferably, the pin receptacle 62 is formed by the housing base 5 and the cover 58.

[0144] The pin receptacle 62 is designed to open in a radial direction so that the hinge pin 61 can be pulled out of the pin receptacle 62 in the radial direction along an insertion channel 63 extending in the direction of the connection area AB in order to remove the locking flap 6 .

[0145] Preferably, the locking flap 6 comprises a pivot arm 64 on which the hinge pin 61 is arranged. The pivot arm 64 can be designed to be at least partially tapered in order to provide a theoretical breaking point 65 at which the pivot arm 64 breaks if, for example, the locking flap 6 is moved further beyond the limit of the hinge pin 61. Figure 7a and Figure 7b If the opening position shown in FIG is not shown, this is because, for example, a person hooks onto the opened closing flap 6 when passing by.

[0146] The control electronics area SB is provided with Figure 9a The control electronics 7 shown in FIG. Figure 9b The control electronics area SB is shown in cross section in FIG.

[0147] The control electronics 7 comprises, for example, a first printed circuit board 71 a having a first control circuit and a second printed circuit board 71 b having a second control circuit.

[0148] Furthermore, the control electronics 7 can be connected to one or more cables K via a connection assembly. To this end, the connection assembly can include a plurality of connection units, in particular a first connection unit provided on a first circuit board 71 a and a second connection unit provided on a second circuit board 71 b. The first and second connection units can each include one or more connectors 72 for connecting the cables K.

[0149] The partition wall 52b preferably comprises a plurality of connection openings through which the connector 72 is accessible and / or through which the connector 72 protrudes into the wiring area AB, so that one cable K can be connected to the connector 72 in each case, as will be described below, in particular in Figure 10a As can be seen in.

[0150] As in Figure 9a As shown in the figure, the connecting component can include connecting units, in particular connectors 72, which are arranged at opposite edges of circuit boards 71a, 71b, so that in a control device 4 having two connection areas AB, there is also at least one connecting unit pointing towards each connection area AB.

[0151] Furthermore, the second circuit board 71b is preferably shorter than the first circuit board 71a in the direction of extension, particularly in the longitudinal direction of the circuit boards 71a, 71b. The first and second circuit boards 71a, 71b are arranged centered one above the other in the longitudinal direction. The connectors 72 are preferably oriented such that the wiring direction AR extends parallel to the longitudinal direction of the circuit boards 71a, 71b. Consequently, the connectors 72 of the second connection unit are also arranged offset from the connectors 72 of the first connection unit in the wiring direction AR.

[0152] Preferably, the longitudinal direction extends orthogonally to the previously described opposing edges of the printed circuit boards 71 a , 71 b , at which the connections 72 are provided.

[0153] In the connection area AB, markings may also be provided, for example, on or in the rear wall 51 and indicating the cable path and / or the connection 72, as can be seen in FIG7 . This facilitates the assembly, in particular the connection, of the cable K. The markings may be printed, embossed, etc., for example.

[0154] In order to achieve a small overall height, provision can be made for the first printed circuit board 71 a , the second printed circuit board 71 b and the rear wall 51 to be arranged parallel to one another and stacked one on top of the other in the depth direction TR.

[0155] Furthermore, the control electronics 7 may be included in Figure 9b An optional processor module 73 is schematically shown, disposed between the first circuit board 71a and the rear wall 51. Preferably, the processor module 73 and the first circuit board 71a are stacked one on top of the other. It may be desirable for the rear wall 51 to include a recessed portion adapted in shape and size for the processor module 73, with the processor module 73 at least partially accommodated within the recessed portion. Furthermore, an optional thermal pad 74 may be disposed within the recessed portion to thermally connect the processor module 73 to the metal plate 57.

[0156] exist Figure 10a and Figure 10b shows a perspective view of the connection area AB. The locking flap 6 is not shown here. As can be clearly seen, a plurality of cables K are guided through through openings 53 into the connection area AB and connected to connectors 72 of the control electronics 7. The through openings 53 are preferably designed as upwardly open slots. To seal the connection area AB, a sealing element 54, in particular a foam rubber, can be inserted into the through openings 53.

[0157] Outside the connection area AB, the cable K is guided via a guide surface 55 through the opening 53. The cable K is accommodated between the guide surface 55 and an arcuate guide element 56.

[0158] exist Figure 10a It can also be seen that some of the cables are preferably guided through the through-opening 53 at a first height and other cables are preferably guided through the through-opening 53 at a second height into the connection area AB. For this purpose, the through-opening 53, in particular the lower edge of the through-opening 53, can be arranged at different perpendicular distances from the rear wall 51 in the depth direction TR. Similarly, it can be provided that the guide surface 55 adjoins the through-opening 53 at different perpendicular distances from the rear wall 51. As shown in Figure 10a As can be seen in FIG, the guide surface 55 is designed as a step in the width direction of the control device 4. The step height preferably corresponds to the distance between the first printed circuit board 71a and the second printed circuit board 71b.

[0159] As in Figure 10b As shown in FIG, a plurality of the above-described cable fixing devices 1 are preferably provided in the connection area AB, by means of which cables K can be fixed.

[0161] The frame profile 91 is preferably C-shaped and comprises a base 92 and two legs 93 protruding from the base 92. Mounting sections 94 are arranged on the legs 93 and are aligned with each other and oriented parallel to the base 92.

[0162] In addition, a first hanging tongue 81a and a second hanging tongue 81b are provided on the rear wall 51 of the control device 4. The first hanging tongue 81a faces the first longitudinal side of the rear wall 51, so that one of the assembly sections 94, in particular the upper assembly section 94, can be accommodated between the first hanging tongue 81a and the rear wall 51. In addition, the second hanging tongue 81b faces the second longitudinal side of the rear wall 51, so that the other assembly section 94, in particular the lower assembly section 94, can be accommodated between the second hanging tongue 81b and the rear wall 51, as shown in FIG.
