description Technical Field The present invention relates to the field of transportation and conveyor technology. It relates to a conveyor unit for the hanging transport of transport elements, in particular transport bags and hangers, in a conveyor system, in particular a rail-guided conveyor system or a conveyor chain system. It further relates to a conveyor system with such conveyor units, a method for introducing piece goods into transport elements of a conveyor system, and a method for the visual inspection of hangers or items of clothing hung on hangers. Technological Background In automated warehouses, extensive manufacturing facilities, and more generally in the conveyance and transportation of goods, overhead conveyor systems have proven to be an efficient means of transportation, intermediate storage, but also long-term storage of various types of goods. In the case of overhead conveyor systems, the goods are either suspended in a suitable manner directly on individual conveyor elements of a conveyor system, for example clothes hangers with items of clothing suspended thereon, or are introduced into corresponding transport elements such as, for example, transport bags, which in turn are suspended from the conveyor elements. Overhead conveyor systems can be implemented as conveyor chain systems in which a plurality of conveyor elements form links in a chain which is moved along a conveyor path. Gravity-assisted conveyor systems are also known, in which individual conveyor elements equipped with wheels move on corresponding tracks. An example of such a gravity-fed, rail-guided conveyor system is known from WO 2016/030 275 A1 by the applicant. Overhead conveyor systems with transport elements are particularly suitable for the efficient conveyance of heterogeneous general cargo, such as workpieces in production processes, spare parts, consumer goods such as books, clothes, shoes, etc. Hanging conveyor systems can be used, for example, in logistics centers of mail order companies to store a large number of articles of different sizes and weights, and to pick groups of articles according to the respective customer orders and to prepare them for shipping. A relevant aspect for a overhead conveyor system is the simple, smooth and efficient introduction of goods into empty transport elements and removal of the goods from the transport elements. Manual filling of empty transport elements provided, such as transport bags, allows flexible handling of various goods, but is slow and costly. EP 2 196 415 A2 describes a loading station for transport bags transported in a overhead conveyor system. The transport bags have a stiffened wall in the conveying direction with a hanging hook at an upper end, which is suspended from a carriage. The wall is aligned transversely to the conveying direction. A fabric panel is attached to a pivotable frame bracket attached to the upper end of the wall and to the lower end of the wall, so that a laterally open bag is formed. An empty transport bag is fed vertically from above via a chain drive. Appropriate lateral guide elements on the frame bracket and at the lower end of the wall bring the bag into an open state and fill it via a conveyor belt and a slide. The filled transport bag is then removed. During the filling process, a transport bag has to be laboriously guided over two corners, which limits the throughput and increases the construction volume of the device. [0010] DE 102 004 018 569 A1 shows a further device for loading transport bags in a overhead conveyor system. The transport bags have a frame bracket which is suspended transversely to the conveying direction on a conveying element and which defines an upper opening of the bag. A flexible fabric web attached to the frame bracket at two ends forms a bag for holding piece goods elements. Side walls close only a lower part of the sides of the bag, so that side insertion openings remain. When moving the transport bags along the conveying path through the device, appropriately designed backdrops move the frame bracket, which hangs vertically when the transport bag is empty, into a horizontal position in which the lateral insertion openings are maximally open. The articles can now be put into the pocket manually through the side openings. Automatic filling is not possible because the upper openings of the pockets are not accessible due to the conveyor rail. [0011] EP 2 418 160 A1 shows another loading station for transport bags transported in a overhead conveyor system. The transport bags have a frame bracket suspended from a conveyor element, to which two ends of a flexible fabric web are fastened and form a bag. A pressure plate is arranged below the hanging hook of the bag. A skid is arranged in the loading station, which, when a transport bag moves through the loading station, presses the pressure plate and thus also the transport bag from an orientation transverse to the conveying direction into an orientation parallel to the conveying direction and keeps it in this orientation over the course of the skid. The shape of the suspension hook is chosen so that it is in the support hook of the conveyor element away from a minimum of CH 713 405 A2 potential energy is pushed upwards. At the same time, the frame bracket is also pressed outwards perpendicularly to the conveying direction and assumes a position in which the bag is open towards the top. In this position, the transport bag can be filled from the side through the upper opening. After leaving the area of the runner, the suspension hook on the support hook slides back to the minimum of potential energy and the bag swings back in an orientation transverse to the conveying direction. [0012] DE 102 012 018 925 A1 discloses yet another loading station for transport bags transported in a overhead conveyor system. The transport bags have a rear wall suspended transversely to the conveying direction on a conveying element as well as a front wall and a bottom. When passing the loading station, two ramps push the side wing areas of the rear wall of the transport bag upwards, so that the bag with the horizontal rear wall finally moves in the conveying direction. The goods can now be inserted laterally through the open sides into the bag or thrown in through the upper opening of the bag against the direction of conveyance. [0013] There is a general need for progress in this area of technology.

[0035] The transport bag can be brought from the second state into the first state particularly advantageously by lifting the front wall. The transport element advantageously has at least one second hook. Alternatively, the transport element of a conveyor unit according to the invention (can be a clothes hanger, in particular a hanger clothes hanger or a clamp hanger).

The rearrangement of the transport elements, for example transport bags and coat hanger elements, is advantageously carried out by rotating the transport elements themselves, advantageously about a central axis. A brush arrangement or mechanical, electrical, magnetic or pneumatic actuation means are particularly advantageously provided as the active arrangement. Alternatively, in an advantageous conveyor system in a certain section of the conveyor path, the support hook of the conveyor unit is oriented such that the suspension hook of the transport element is in a first stable position CH 713 405 A2, and is aligned in a certain other section of the support hook of the conveyor unit such that the suspension hook of the transport element assumes a second stable position. It is particularly advantageous to transfer the suspension hook from the first stable position to the second stable position or from the second stable position to the first stable position by the rotation of the conveying element about the conveying direction during the transition between the particular section and the particular one initiated another section of the funding path. In the above-mentioned conveyor systems with transport bags, further opening means can be provided with which a transport bag can be brought into the first open state at a specific point on the transport path, the suspension hook being in the second position and the rear wall of the transport bag essentially is oriented parallel to the direction of conveyance. [0046] A lifting arrangement, in particular a lifting table or a ramp arrangement, is particularly advantageously provided as the opening means. The opening means can also be designed as a ramp, which is arranged such that the bottom portion of an empty pocket is continuously raised during the conveyance from the ramp, so that the transport pocket changes to the first, opened state. Another possibility is the use of a ramp-shaped conveyor belt, which runs analogously to the ramp mentioned above, but has the advantage that the transport bag is actively moved at its lower end, so that the opening of the bag can take place in a very controlled manner. Furthermore, such an advantageous conveyor system can have a device for introducing piece goods units into the open pocket of the transport bag. A plurality of transport bags can be provided in a shingled arrangement in a preparation section of the conveyor path of the conveyor system. The support hooks of the conveyor units are advantageously designed in such a way that they permit such a scaled arrangement. The support hooks advantageously have a storage segment which, in the scaled arrangement of the transport pockets, enables a stable position of the suspension hooks. Such flaky arrangements of transport bags can be used anywhere in a conveyor system. They can be used for different applications and to fulfill different functions within a conveyor system. It is also possible to convey and move entire groups of such transport bags in a shingled arrangement together within the conveyor system.

[0060] In one of the aforementioned methods, the transport bag is transferred from the second state into the first state particularly advantageously before the introduction of a unit load unit into the pocket of the transport pocket of a conveyor unit. In the above-mentioned methods, a plurality of transport bags are advantageously provided in a shingled arrangement. [0062] A method according to the invention for the visual inspection of items of clothing suspended on clothes hanger transport elements of a conveyor system comprises the steps: - Provision of a conveyor system according to the invention as discussed above; Feeding a conveyor unit of the conveyor system along the conveyor path, the hanging hook of the hanger transport element being in the first stable position; - Transfer the hanging hook of the hanger transport element of said conveyor unit from the first stable position to the second stable position; - visual inspection of the front and / or back of a piece of clothing suspended on the hanger transport element; and - Transfer the hanging hook of the hanger transport element from the second stable position to the first stable position.

WAYS OF IMPLEMENTING THE INVENTION A first possible embodiment of a conveyor unit 10 according to the invention is shown in FIG. 1. A transport element 40 in the form of a transport bag has a hanging hook 41 which is suspended in a carrying hook 21 of a conveying element 20. In the example shown, the conveying element is a carriage of a gravity-conveyed overhead conveyor system, analogous to the system as disclosed, for example, in WO 2016/030 275 A1 by the applicant. For a better understanding, the carriage 20 is shown on a running track 86 of a conveyor system, where it moves in an intended conveying direction 82. The transport bag comprises a front wall 44, a bottom portion 45 and a rear wall 42, which are pivotally connected at the abutting edges. The front wall, rear wall and arch section are designed to be stable and can be made, for example, from a suitable plastic material, for example a twin-wall sheet. Flexibly designed side walls 46 connect the front wall, rear wall and bottom section, so that a pocket 47 results with an opening into which at least one piece goods unit 70 can be loaded. In the example shown, the side walls are made from a fine-mesh network. It is also possible to use a flexible textile material. The side walls 46 are designed such that they can also be folded up when the transport bag is folded up, as described below. Between front wall 44 and rear wall 42, a pivotably fastened spacer 50 in the form of a wire bracket is arranged on each side. The spacers 50 are arranged essentially parallel to the bottom section 45 and have the same length as the bottom section, and the front wall 44 lies essentially parallel to the rear wall 42, so that the rear wall 42, spacers 50, front wall 44 and bottom section 45 form a parallelogram. In the unloaded state, the weight of the front wall and base section let the front wall sink downward, so that the transport bag changes into a second state, in which the front wall and rear wall lie close together. In this configuration, the transport bag can be stored in a space-saving manner in a conveyor system, in that the conveyor units are lined up one behind the other on a running rail. By lifting the front wall 44 and / or the bottom section 45 relative to the rear wall 42, the transport bag can be transferred from the second, folded state into a first, unfolded state, as shown in FIG. 1. The upward opening of the pocket 47 of the transport pocket 40 now has the maximum size. In the exemplary embodiment shown, a piece goods unit is arranged in the pocket 47 of the transport pocket 40, represented schematically by a cuboid-shaped object 70. CH 713 405 A2 Two guide rollers 54 are arranged at a lower end of the rear wall 42. These can be used to additionally move the transport bag 40 when conveying in a conveyor system when moving along the conveying direction 82, for example by guiding one or both guide rollers in a link. Similarly, the two guide rollers 55 attached to an upper end of the front wall 44 can be used to raise the front wall 42. The rear wall 42 is extended at its upper end into a support section 43, at the upper end of which the suspension hook 41 is pivotally connected to the rear wall 42 or its support section 43 in the form of a wire bracket. The bracket of the suspension hook 41 defines an orientation plane of the suspension hook, and thus the entire transport bag. The supporting hook 21 is attached to a lower end of the carriage 20 facing away from the running rail 86. It can be made from metal or from a suitable polymer material, for example a glass fiber reinforced thermoplastic material. The support hook 21 has a closed bracket in the assembled state with two bearing segments 22, 23. When the carriage is in a horizontal position, the first support segment 22 corresponds to the lowest point of the bracket of the support hook. 1, the suspension hook 41 is in a first stable position, in which the suspension hook is supported in the first storage segment 22 with a minimum of potential energy. In this stable position, the suspension hook 41 is aligned in a plane transverse to the conveying direction 82, and a front side 48 of the pocket of the transport pocket looks in the conveying direction 82. In this context, the term “transverse” should be understood to mean any orientation of the suspension hook plane in which the suspension hook is not essentially parallel to the conveying direction 82 in one plane. In the example shown, the suspension hook, like the rear wall 42, lies in a plane perpendicular to the conveying direction 82. However, other angles would also be possible, in which transport bags can be stored in a row in a space-saving manner on the running rail in an empty or filled state. A little higher than the first bearing segment 22, a second bearing segment 23 is present on the support hook 21, delimited by a small projection 25 on the bracket of the support hook. This second bearing segment 23 also corresponds to a local minimum of the potential energy of the suspension hook 41 suspended in the support hook. The suspension hook is stable in this second position. The suspension hook must be lifted over the protrusion 25 to move from the first stable position to the second stable position and vice versa. In the second stable position, the suspension hook is aligned in one plane essentially parallel to the conveying direction. The term “essentially parallel” is to be understood in such a way that if the suspension hook and the rear wall of the transport bag are aligned accordingly, the opening of the bag for filling is easily accessible from the side, that is to say transversely to the conveying direction. In the exemplary embodiment shown, the second stable position corresponds to an orientation of the suspension hook plane parallel to the conveying direction 82. However, an alignment would also be possible, for example, at an angle of 30 ° to 45 ° to the conveying direction 82. In such a position, a transport bag is also loaded the side possible, but smaller angles of 30 ° or smaller are more advantageous for automated loading processes, since the minimum necessary distance between the opening of the transport bag and a feed device becomes smaller. This distance is minimal for an angle of 0 °, ie when the suspension hook is oriented in a plane parallel to the conveying direction. A conveyor unit 10 according to the invention with an alternative embodiment of a transport element 40a is shown in FIG. 1A. The transport element 40a essentially corresponds to the transport bag from FIG. 1, without guide rollers. A second hook 58, to which a further transport element can be attached, is arranged in the center on the rear end of the transport bag 40a at the lower end of the carrying section 43. In the exemplary embodiment shown, a clothes hanger 240 is hung by way of example with the hook 241 on the second hook 58 of the transport bag 40a. Such a transport bag has the advantage that not only general cargo 70 can be transported and / or stored with the transport bag, but additionally or alternatively also items of clothing on hangers. Accordingly, only one transport system is required both for piece goods that can be placed in the pocket 47 and for goods that usually have to be stored hanging, for example items of clothing on hangers. The second hook can be attached to a lower end of the support section, as in the example shown, or further up. For example, a hook 58 'may be attached to the upper end of the support section, as shown in dashed lines in FIG. 1A. Two or more hooks can also be attached. A second possible embodiment of a conveyor unit 10 according to the invention is shown in FIG. 2. Carriage conveyor element 20 and transport bag 40 with suspension hooks 41 correspond to the exemplary embodiment in FIG. 1, and have already been discussed there accordingly. The carrying hook 21 has two bearing segments 22, 23, both of which correspond to a local minimum 65, 65 'of the potential energy of a hanging hook 41 suspended in the carrying hook 21. In Fig. 2 (a) the suspension hook 41 is located on the first storage segment 22 and takes a first stable position in the corresponding local minimum 65 of the potential energy. The suspension hook 41 and thus the rear wall of the transport bag 40 occupies a plane transverse to the running direction 82 of the carriage 20. In Fig. 2 (b) CH 713 405 A2, on the other hand, the suspension hook 41 is located on the second bearing segment 23, and assumes a second stable position on this local minimum 65 ′ of the potential energy, in which it is aligned in a plane essentially parallel to the running direction 82. In order to get back and forth between the first stable position and the second stable position, the suspension hook must overcome an intermediate raised area 25 of the bracket of the support hook 21. In the aforementioned two exemplary embodiments of a conveyor unit according to the invention, the suspension hook can be transferred back and forth between the two stable positions by rotating the suspension hook or the transport bag about the longitudinal axis. The suspension hook overcomes the separating area 25 between the two bearing segments 22, 23. FIG. 2A shows a further embodiment of a conveyor unit 10 according to the invention. The carriage conveyor element 20 and the support hook 21 correspond to the embodiment in FIG. 2 and have already been discussed there accordingly. The transport element 40 is a coat hanger element in the form of a hanger coat hanger 240 with hanging hooks 241. A piece of clothing is hung on the coat hanger during operation, but is not shown for the sake of clarity. Analogously to FIG. 2, the hanging hook 241 of the clothes hanger 240 can assume two stable positions 61, 61 'in the carrying hook 21. In a first stable position 61, as shown in FIG. 2A (a), the suspension hook 241 is supported on a first mounting segment 22 of the support hook 21. The plane of the hanger element 241 is essentially transverse to the conveying direction 82. In a second stable position 62, As shown in FIG. 2A (b), the suspension hook 241 is supported on a second mounting segment 23 of the support hook 21. The plane of the hanger element 241 is essentially parallel to the conveying direction 82. An orientation of the bracket level transverse to the conveying direction allows space-saving conveying and storage of the loaded conveying units. Alignment parallel to the direction of conveyance, on the other hand, allows, among other things, a view of the front and back of the item of clothing being transported, for example for a visual inspection of a returned item of clothing. A possible embodiment of a conveyor system according to the invention is shown in FIG. 3, with an arrangement for loading transport bags. The conveyor units 10 essentially correspond to those from FIG. 1, the carriages 20 being shown schematically in a simplified manner. From the left, a transport bag 40 is gravity-fed through a slightly inclined section of the running rail 86. The suspension hook is in the first stable position and is aligned transversely to the conveying direction 82 together with the rear wall of the transport bag 40. The still empty transport bag 40 is in the second, folded state, in which the front wall 44 and bottom section 45 hang vertically on the spacer elements 50, and the bag has a minimal thickness. A bag 40 'is now conveyed to the right with corresponding external drive means (not shown) to a first active arrangement 90 for the active rotation of the transport bag. In the exemplary embodiment shown, the active arrangement 90 is designed as a brush arrangement, namely as a brush turntable that can be raised and lowered vertically. If the transport bag is still in the first stable position above the turntable, the turntable is raised and contacts the bottom part of the bag, namely the connecting edge between the front wall and the bottom section. The brush turntable 90 now rotates 90 ° clockwise, dragging the transport bag 40 'with it, which accordingly rotates about the axis of the support hook. The suspension hook moves from the first stable position to the second stable position, in which the suspension hook is parallel to the conveying direction 82. The brush turntable 90 lowers again and the transport bag 40 'remains in the second stable position. The rotation through the active arrangement does not necessarily have to take place over the entire angle of rotation. It is sufficient if the suspension hook is rotated so far that it overcomes the elevation of the bracket of the support hook between the two bearing segments. The suspension hook then automatically moves into the second stable position and orientation by gravity. The transport bag 40 is now conveyed further to the right, to an opening means 100 for transferring the transport bag into an open state. In the exemplary embodiment shown, the opening means is designed as a lifting table 100, which lifts the front wall 44 of the transport bag 40 and thus transfers the transport bag into the first state. The opening of the pocket 47 of the transport bag is now open at the top. A piece goods unit 70 can now be inserted into the pocket 47, as shown schematically in the figure. The piece goods unit 70 can be introduced by manual or automated insertion or insertion, for example via a slide, a conveyor belt or a robot arm. [0094] The lifting table 100 is then lowered again. Since the pocket 47 is no longer empty, the transport pocket cannot return from the first state to the second state and remains in a filled intermediate state. The now loaded bag 40 'is conveyed further to the right, the suspension hook still being in the second stable position. With a further active arrangement 90 'in the form of a turntable that can be raised and lowered, the transport bag 40' is rotated counterclockwise back into the first stable position. The hanging hook and CH 713 405 A2 the transport ash are now again at right angles to the conveying direction 82. The filled transport pocket is conveyed further to the right and transported in the conveyor system 80 in accordance with its further purpose. Another possible embodiment of a conveyor system 80 according to the invention is shown in FIG. 3A. The conveyor units 10, which are only shown schematically, comprise support hooks 41, as have already been discussed above. No transport bags, but clothes hangers 241 are provided as transport elements. [0097] From the left, a clothes hanger transport element 40 loaded with a piece of clothing 75 is fed under the force of gravity via a slightly inclined section of the running rail 86. The suspension hook 241 is in the first stable position and the plane of the clothes hanger 241 is oriented transversely to the conveying direction 82. A clothes hanger transport element is now conveyed to the right with corresponding external drive means (not shown) to a first active arrangement 90 for the active rotation of the clothes hanger. The active arrangement 90, which is only shown schematically, can be configured, for example, as a brush arrangement which, by means of gentle radial force, brings the clothes hanger transport element 40 'into the second stable position in the counterclockwise direction with respect to the carrying hook. The hanging hook 241 moves from the first stable position to the second stable position, in which the hanging hook and the plane of the clothes hanger are parallel to the conveying direction 82. The clothes hanger transport element 40 'is now conveyed further to the right, where a camera 95 records the front of the transported article of clothing 75. At the same time, another camera (not shown) can record the back of the garment. These recordings can then be used to check, for example, the type of a piece of clothing and its condition (for example, for returns in the mail order business). Such a visual inspection can also be carried out with the human eye instead of using electronic means. The clothes hanger transport element 40 is further conveyed to the right, the suspension hook being still in the second stable position. With a further knitting arrangement (not shown), the clothes hanger transport element 40 is rotated clockwise back into the first stable position. The suspension hook and the clothes hanger transport element are now again transverse to the conveying direction 82. The clothes hanger transport element is conveyed further to the right and transported further in the conveyor system 80 in accordance with its further purpose. [0101] A further possible embodiment of a conveyor system 80 according to the invention is shown schematically in FIG. 4. A plurality of conveyor units with still empty transport pockets 40 'in the folded second state are provided in a feed area in a shingled arrangement to save space. The pockets can, for example, be brought into and held in the scaled arrangement by corresponding guide means 102. In this scaled arrangement, the suspension hooks and the transport bags are already rotated transversely to the conveying direction 82 with respect to the first stable position. If the foremost transport pocket of the shed arrangement is now conveyed further to the right, in the exemplary embodiment shown a bracket 103 presses this pocket further clockwise around the vertical, so that the suspension hook now automatically changes into the second stable position parallel to the conveying direction 82. The pocket 40 can now be brought back into the first state with a suitable opening means 100. After the transport bag 40 'has been loaded, it is again moved into the first stable position using suitable means (not shown) and passed on to the conveyor system 80 for further use. The exemplary embodiment from FIG. 4 has the particular advantage that the cycle time can be reduced. An empty transport bag to be filled only has to be fed over a short distance and has already been rotated to a considerable extent from the first stable position towards the second stable position. The remaining pivoting of the transport bag in an alignment plane parallel to the conveying direction then takes place essentially automatically. In a further, not shown embodiment of a conveyor system, the rotation of the supplied empty transport bags takes place through scenes for the guide rollers 54. While a transport bag is fed in the first stable position transversely to the conveying direction 82, one or both of the guide rollers 54 of the pocket slide in a backdrop or guide rail. By suitably arranging the guide rail, the transport bag is rotated about the axis of the carrying hook during further conveyance of the transport bag along the conveying path and reaches the second stable position. The guide scenes are no longer necessary. After the transport bag has been opened and filled, it can be pivoted from the second stable position into the first stable position in an analogous manner. This variant has the particular advantage that a transport bag does not have to be stopped to rotate between the first and the second stable position, which reduces the cycle time. The various active arrangements shown for rotating the transport bags can also be combined. In addition, the person skilled in the art can use other actuating means with which a rotation of the transport bags can be achieved. For example, rotating devices can be provided which abut the pockets and thus cause rotation. Linear actuators that bump into a pocket and can thus rotate are also possible. The opening means can also be designed as a ramp, which is arranged such that the bottom portion of an empty pocket is continuously raised by the ramp during conveyance, so that the pocket changes to the first, open state. CH 713 405 A2 A further possibility is the use of a ramp-shaped conveyor belt which runs analogously to the ramp mentioned above, but has the advantage that the transport bag is actively moved at its lower end, so that the opening of the bag takes place in a very controlled manner can. In a further, third possible embodiment of a conveyor unit according to the invention, as shown in FIG. 5, the transition between a first stable position and a second stable position of the suspension hook takes place by rotating the support hook 21 in space. Conveyor element 20 and transport bag 40 with suspension hook 41 again correspond to the exemplary embodiment in FIG. 1, and have already been discussed there accordingly. The support hook 21 of the conveyor unit 10 is configured in such a way that in two specific positions of the support hook 21 in space, one mounting segment corresponds to a minimum of the potential energy of the suspension hook 41 in the support hook 21. The first stable position is not shown in FIG. 5. It essentially corresponds to the situation in FIG. 2 (a), in which the carriage 20 is arranged horizontally on the running rail 86, and the support hook 21 is oriented essentially vertically downwards. The suspension hook 41 is in the first stable position in the local minimum 65 of the potential energy, on the first storage segment 22. The suspension hook 41 is aligned in a plane transverse to the conveying direction 82. In the situation as shown in FIG. 5, however, the running rail 86 and the carriage 20 mounted thereon are rotated through an angle of approximately 45 ° about the conveying direction 82. Accordingly, the support hook 21 is rotated by an angle of approximately 45 ° from the vertical. In this orientation of the support hook 21 in space, the first support segment 22 no longer corresponds to the second support segment 23 but a minimum 65 'of the potential energy of the suspension hook 41 in the bracket of the support hook 21. The suspension hook 41 is in a second stable position, and is aligned in a plane essentially parallel to the conveying direction 82. The transfer of the suspension hook back and forth between the first stable position and the second stable position is carried out in the exemplary embodiment shown by rotating the support hook 21 together with the carriage 20. This can be achieved in a simple manner by a over a sufficiently long area twisted running track 86 is provided. When the carriage 20 is conveyed by a corresponding section of the running rail 86, the carriage 20 and thus also the support hook 21 are also rotated. At the same time, the suspension hook 41 is lifted into a new, unstable position in the bracket of the carrying hook 21 and slides under the force of gravity from the first, no longer stable position to the second stable position, or vice versa. The suspension hook 41 accordingly pivots back and forth between the associated alignment levels. This embodiment of a conveyor unit has the particular advantage that the rotation of the suspension hook can be integrated directly into the conveying process without a conveyor unit having to be stopped or braked to rotate the suspension hook and the transport bag. Accordingly, short cycle times are possible. A further advantage is that different types of transport elements, for example transport bags and clothes hangers, can be used at the same time without the need for different active arrangements for the different types of transport elements. [0116] The embodiment variant shown can of course also be realized with clothes hanger transport elements. The rotation of the hanging hook and the clothes hanger without interrupting the conveying process is particularly advantageous for an automatic visual inspection with a high cycle rate, for example for a quality control within a manufacturing process. A fourth possible embodiment of a conveyor unit 10 according to the invention with a transport pocket 340 as a transport element 40 is disclosed in a detailed view in FIG. 6. The trolley 20 is only shown schematically. From the transport bag 340, only the suspension hook 341a, 341b and the upper end of the carrying section 343 are visible. The transport bag 340 otherwise corresponds to the transport bags from FIGS. 1 and 1A. The support hook consists of a first support hook element 321a and a second support hook element in the form of a bolt 321b, which connects the first support hook element 321a to the carriage 20 such that it cannot rotate. The first support hook element 321 consists of a cylinder aligned with the bolt 321b. The end face of the cylinder facing the carriage 20 is advantageously designed as a corrugated bearing surface 326. This has radially evenly spaced, radially symmetrical depressions 324 and elevations 325. In the exemplary embodiment shown, the angle between two depressions is 90 °. [0119] The suspension hook of the transport bag consists of two elements 341a, 341b. A lower, bow-shaped, second element 341b is connected to the carrying section 343 of the transport bag. At the upper end, the bow-shaped, second support hook element 341 b is connected to a first support hook element 341 a. Depending on the intended application, the bracket 341b can be connected to the first support hook element 341a so as to be pivotable about a horizontal axis, or it can be secured against rotation. The first support hook element 341a is configured analogously to the first support hook element 321a, with a corrugated bearing surface facing the support section with four depressions and four elevations, which lies flush on the corrugated support surface of the first support hook element 341a. In the center of the first support hook element 341a there is a through hole through which the bolt 321b runs. CH 713 405 A2 In the first stable position shown in FIG. 6 (A), the carrying section of the transport bag is oriented essentially transversely to the conveying direction. An increase marked “A” on the bearing surface of the first suspension hook element 341a lies in a depression marked “B” in the bearing surface of the first support hook element 321a. If the transport bag 340 is now rotated along the axis by the bolt 321b, the increase "A" of the bearing surface of the first suspension hook element 341a slides upward on the bearing surface of the first support hook element 321a, overcomes the increase in the bearing surface marked "D" of the first Support hook member 321a, and slide back down to a stable position as shown in Fig. 6 (b). The increase “A” in the bearing surface of the first suspension hook element 341a now lies in the depression of the bearing surface of the first support hook element 321a marked “C”. The suspension hook is now in a second stable position in which the carrying section 343 of the transport bag runs essentially parallel to the conveying direction 82. [0121] The angle between the first stable position and the second stable position of the suspension hook 341a on the support hook 321a is given by the angle between two adjacent ridges 325. In the exemplary embodiment shown, the angle is correspondingly 90 °. However, other angles can also be realized, for example 30 °, 45 ° or 120 °, as long as an integer multiple thereof results in 360 °. Such a conveyor unit is particularly advantageous because it not only allows a rotation between two stable positions back and forth, but a further rotation of the suspension hook in both directions, in each case in the predetermined discrete angular steps. [0123] The first support hook element 321a and the first suspension hook element 341a can be inexpensively manufactured with injection molding from a suitable plastic material, for example from HDPE. A fifth possible embodiment of a conveyor unit 10 according to the invention is shown in FIG. 7. The support hook 321 a, 321 b corresponds to that from FIG. 6, as does the first suspension hook element 441 a. The second suspension hook element 441b is designed as a closed bracket. A hook 243 of a clothes hanger 240 is in turn suspended in this bracket. [0125] A sixth possible embodiment of a conveyor unit 10 according to the invention is shown in FIG. 8. The transport element 40 is designed as a clothes hanger 540. The support hook consists of two support hook elements 521a, 521b. A first support hook element 521a comprises a corrugated bearing surface analogous to the embodiments in FIGS. 6 and 7. This is connected to a carriage 20 by two rods of the second support hook element 521b. The suspension hook of the transport element 40 consists of two suspension hook elements 541a, 541b. A first suspension hook element 541 a comprises a corrugated bearing surface analogous to the embodiments in FIGS. 6 and 7. The second suspension hook element in the form of a rod or bolt 541 b runs through a bore in the first support hook element 521 a and connects the first suspension hook element 541 a to the Coat hanger 540. Such a variant of a conveyor unit according to the invention is particularly advantageous in cases where garments are temporarily hung on hangers for further processing, for example for processing returns in the mail order business, or for cloakrooms. The scope of the present invention is not limited to the specific embodiments described here. Rather, for the person skilled in the art, from the description and the associated figures, in addition to the examples disclosed here, various further modifications of the present invention result, which also fall within the scope of the claims. In addition, various references are cited in the description, the disclosure content of which is hereby incorporated in its entirety by reference in the description.
