DESCRIPTION OF THE EMBODIMENTS
[0057] Reference is now made in detail to certain embodiments exemplified in the accompanying drawings, in which some but not all features are shown. Indeed, the embodiments disclosed herein may be embodied in many different forms and should not be understood to be limited to the embodiments set forth herein; rather, these embodiments are provided in order for this disclosure to comply with applicable legal requirements. Whenever possible, like reference numbers are used to refer to like components or parts.
[0058] FIG. 1 shows a first embodiment of an suspended conveyor 1 according to the disclosure in a perspective view. The suspended conveyor 1 has a rail 2 and a conveying means 3 movably mounted thereon. In the embodiment shown here, the conveying means 3 is a continuous conveying means 3 consisting of individual, interconnected links. The conveying means 3 has carriers 4 for detachably holding suspended transport means 5. The carriers 4 are each rod-shaped and connected to the links. The carriers 4 of the first embodiment can each carry one or more transport means 5. The transport means 5 are designed here as clothes hangers with a holding means 25, in particular a hook 25. For spacing individual hooks 25, at least one of the carriers 4 preferably has one or more protrusions 28, which are designed to support a respective hook 25 during transportation. Alternatively, or in addition to the bulges 28, recesses are also conceivable. During operation, the conveyor 3 moves the clothes hangers 5 along the rail 2 in the conveying direction X.
[0059] FIG. 2 shows a first embodiment of an clearing arrangement according to the disclosure in a perspective view and FIG. 3 shows an enlarged view of the first embodiment of an clearing arrangement according to the disclosure. The first embodiment of a clearing arrangement 6 shown in FIG. 2 comprises a clearing device 8 and an actuating arrangement 11. The clearing arrangement 6 is designed for clearing at least one section of the rail of transportation means. The clearing device 8 is movably arranged with a guide bearing 9 along the rail section 7. In the embodiment shown, the clearing arrangement 6 comprises a rail segment 29, which is arranged in particular on the rail 2 of the suspended conveyor 1. The guide bearing 9 is movably mounted in the rail segment 29, in particular against or in the conveying direction X. The actuating arrangement 11 is designed to move the clearing device 8 from a standby state to a clearing state. In the embodiment shown, the actuating arrangement 11 is also designed to move the clearing device 8 along the rail section. The clearing device 8 can be moved both along and against the conveying direction X.
[0060] FIG. 3 shows an enlarged view of the clearing device 8 of FIG. 2. The clearing device 8 comprises a clearing element 10. In the clearing state, the clearing element 10 is designed to release the transport means from the carriers in the rail section by a relative movement of the clearing device 8 to the conveying means. In other words, the clearing element 10 releases the hangers from the carriers by moving the clearing device 8 along the rail section. Preferably, the clearing element 10 is also designed to pick up and carry the detached coat hangers in the clearing state. For this purpose, the clearing element 10 preferably has a blade 10 with a release section 20 and an adjoining collection section 21. In particular, the release section 20 has an edge 22 as a contact contour. This contact contour 22 has a starting bevel at the beginning, which establishes contact with the holding means of the transport means during the relative movement thereto. In the clearing position of the blade 10, the edge 22 is aligned in such a way that it forms a slope towards the collecting section 21 for lifting the transport means from the carriers. In the clearing position of the blade 10, the edge 22 is also aligned in such a way that it forms an incline towards the collecting section 21 for moving the transport means sideways away from the carriers. This alignment is particularly clearly visible in FIG. 6.
[0061] FIG. 6 shows the suspended conveyor of FIG. 4 with the first embodiment of the clearing arrangement in the clearing state in a further perspective view. As can be seen, the edge 22 in this embodiment is designed to achieve the lifting and moving away of the transport means 5 from the carriers 4 in a superimposed movement. This is advantageous, as it enables a controlled release of hook-shaped holding means 25. Adjacent to the release section 20, opposite the starting slope, the collecting section 21 is formed as an indentation 23. The indentation 23 has a distal end that is designed as a stop 24, in particular as a lug 24. The indentation 23 allows the detached transport means 5 to be carried safely and minimizes the risk of the detached transport means 5 falling down.
[0062] As can be seen in FIG. 3, the guide bearing 9 forms an abutment for the clearing element 10 in the clearing state, so that rotation of the clearing element 10 about an axis parallel to the conveying direction X is minimized. In particular, double guide bearings 9 are provided for this purpose, whereby each guide bearing 9 is designed as a multi-axis roller bearing in order to increase the torsional rigidity. In order to move the clearing device 8 along the rail section, the actuating arrangement 11 has a cable pull 26, which connects the clearing element 10 to a secured weight 27. Once released, the weight 27 is designed to exert a pulling force on the clearing element 10 by means of the cable pull 26. Preferably, the cable pull 26 connects the clearing element 10 and the weight 27 via one or more deflection pulleys 40.
[0063] FIGS. 7 and 8 each show a side view of the clearing device 8. In the following, the clearing device 8 is described in more detail with particular reference to these figures. In the illustrated embodiment of the clearing device 8, the clearing element 10 is arranged on a base 12 of the clearing device 8 so as to be pivotable about a pivot axis S between a standby position and a clearing position. In the standby position, the pivot axis S is oriented essentially parallel to the gravitational force g, although alternative configurations are also conceivable. Depending on the configuration, the clearing element 10 is aligned parallel to the conveying direction X in the direction of its general extension in the ready position. The clearing element 10 can generally be pivoted between 20 and 90 degrees, preferably by 30 to 70 degrees, between the standby position and the clearing position. In particular, the clearing element 10 is pivotably mounted on the base 12 in such a way that the pivoting movement is stopped when the clearing position is reached.
[0064] FIG. 9 shows a clearing element of the clearing device of the first embodiment in a perspective view from above and FIG. 10 shows the clearing element of FIG. 9 in a perspective view from the side. The clearing element 10, shown in detail in FIGS. 9 and 10 and designed as a blade 10, has a recess 30 designed as a guide slot into which the base engages. The clearing device 8 also has a tilting device. The tilting device is arranged between the guide bearing and the clearing element 10 and is designed to move the clearing element 10 relative to the guide bearing about a tilting axis K from a ready position to a tilting position. As can be seen in particular in FIG. 7, this is achieved in particular by the base 12 being tilted about the tilting axis K when the clearing device 8 is moved from the standby state to the clearing state. Typically, the tilting axis K is arranged parallel to the conveying direction X. In the embodiments shown, the tilting device 13 is designed as a parallelogram. The parallelogram has at least two parallel connecting elements 32, which connect the upper part 33 and the base 12 to each other via pivot bearings. The tilting axis K is parallel to the axes of rotation of the pivot bearings of the parallelogram. In particular, the tilting axis K is identical to the axis of rotation of the pivot bearing 34 of the base 12 facing the rail 2 and the connecting element 32.
[0065] As can be seen particularly clearly in FIG. 10, the clearing element 10 is attached to the base by means of a rotatably mounted bolt 35. FIG. 8 shows that the tilting device 13 preferably has at least one spring element 14, which is pretensioned in the ready position and locked by a retaining element 15. The retaining element 15 is secured in the standby position by a securing finger 16 of the clearing element 10, so that the securing finger 16 releases the retaining element 15 by pivoting the clearing element 10. The pre-tensioned spring element 14 is designed to move the clearing element 10 from the standby position to the tilting position after its release, whereby the base 12 is tilted about the tilting axis K for this purpose. In the embodiment shown, see FIG. 7, the at least one spring element 14 is arranged diagonally between opposing pivot bearings 34 of the parallelogram. After its release, the spring element 14 causes a parallel displacement of the connecting elements 32, so that the base 12 and thus the clearing element 10 are tilted about the tilting axis K.
[0066] FIGS. 12 and 13 show a third embodiment of the clearing device 8 with an alternatively designed tilting device 13. In this embodiment, the cable 26 of the actuating device is connected to one of the connecting elements 32 of the parallelogram 31. The upper part 33 of the parallelogram 31 can be tilted parallel to the base 12 and is suspended centrally on a cantilever arm 36 so that it can be tilted. The cantilever arm 36 extends essentially horizontally and connects the guide bearing 9 with the tilting device 13. FIG. 12 shows the clearing device 8 in the standby state and FIG. 13 shows the clearing device 8 in the clearing state. The actuating arrangement, which is not shown in full, is designed to exert a tensile force on the cable 26 so that this is introduced into the connecting element 32 and the parallelogram 31 is displaced or deformed in such a way that the base 12 is tilted. The clearing element 10 attached to the base 12 is thereby moved into the tilting position or into the clearing position.
[0067] The embodiments shown preferably comprise a stop element, which is arranged on the tilting device, and in particular is arranged on the upper part 33. The clearing device 8 can be designed in such a way that, in the ready position, the stop element rests against a fixed stop in relation to the rail section. This stop holds the clearing device 8 in a start position when the stop element is in contact with it. In the tilted position, the stop element is released from the stop and allows the clearing device 8 to move along the rail section 7. FIG. 11 shows a schematic sectional view of a second embodiment of the clearing device, with the solid lines indicating the ready state and the dashed lines the clearing state. The positions of the stop element 17 are clearly visible here. The second embodiment of the suspended conveyor 1 in FIG. 11 is characterized by a different conveying means 3. In addition to an indicated drive means, the conveying means 3 here comprises a large number of individual carriages on which the clothes hangers 5 are held by their hooks 25.
[0068] FIG. 4 shows a rail section 7 of an suspended conveyor 1 according to the disclosure with the first embodiment of the clearing arrangement 6 in the ready state in a perspective view and FIG. 5 shows the suspended conveyor 1 of FIG. 4 with the first embodiment of the clearing arrangement 6 in the clearing state in a perspective view. Depending on the embodiment, in particular in FIG. 5, the attachment point of the cable pull 26 on the clearing element 10 is offset outwards from the pivot axis. As a result, the tensile force introduced into the blade 10 by the cable pull 26 leads to a torque which acts on the blade 10. This allows the blade 10 to swivel around the pivot axis. As can be seen in FIGS. 3 and 8, a spring element 19 can be arranged between the clearing element 10 and the base 12. When the clearing element 10 is pivoted from the standby position to the clearing position, the spring element 19 overcomes a dead center, making it more difficult to pivot back. Furthermore, the blade 10 is secured in the standby position against unwanted pivoting into the clearing position by the spring element 19.
[0069] FIGS. 14 and 15 show an installation situation of the first embodiment of the suspended conveyor 1 at a fire protection door 37 and a feed-through 38 for the suspended conveyor 1 arranged above it. FIG. 14 shows the suspended conveyor 1 during operation and FIG. 15 shows the same suspended conveyor 1 with the fire protection door 37 in the closed state, whereby the feed-through 38 is filled with a protective material (for example with foam). FIG. 16 shows a side view of the situation in FIG. 14. The clearing device 8 can be seen, which is located at one end of the rail section 7 to be cleared and is connected to the weight via the cable pull. For better understanding, there are transport means 5 in the rail section 7 in the situation shown. For autonomous operation of the clearing arrangement 6, the weight is secured by means of an electromagnet. A possible time sequence for clearing can be as follows, whereby it is clear to the skilled person that the sequence does not necessarily have to correspond to that described and that optional steps are included.
[0070] FIGS. 1 to 3 show that if the rail section 7 is to be cleared of transportation means 5, the electromagnet 39 is switched off and the weight 27 is thus released. The weight 27 then exerts a pulling force on the blade 10 with its weight force via the cable pull 26. The blade 10 is thus pivoted about the pivot axis S and the safety finger 16 of the blade 10 releases the retaining element 15 of the tilting device 13 after partial pivoting. After the release of the retaining element 15, the parallelogram of the tilting device 13 is displaced parallel by the pre-tensioned spring element 14, and the base 12 is tilted or inclined about the tilting axis K. This results in a superimposition of the swivel movement with the tilting movement of the blade 10, particularly in the second part of the swivel movement of the blade 10. The tilting of the tilting device 13 separates the stop element 17 arranged on the upper part 33 from the stop 18. The clearing device 8 is now in the clearing position, with the edge 22 of the blade 10 engaging with the holding means 25 of the transport means 5. As the stop element 17 is released from the stop 18, the clearing device 8 is moved along the rail section 7 against the conveying direction X by the weight 27 via the cable pull 26, as can be seen in FIGS. 5 and 6. Due to the relative movement of the blade 10, the holding means 25, or the clothes hangers 5 of the embodiments shown, are lifted from the edge 22 in a superimposed movement and moved sideways away from the hangers 4 and thus released. The hangers 5 released by the blade 10 are collected in the collecting section 21 of the blade 10 and conveyed out of the sliding section 7.
[0071] The words used in the description are descriptive rather than limiting, and it will be understood that various modifications may be made without departing from the scope of the disclosure.
