Description

Technical field The invention relates to a stacking column for receiving bearing parts on a stacking latch according to the preamble of claim 1. State of the art Such stacking columns are used particularly in the automotive industry to temporarily store sheet metal parts that come from a forming plant and need to be transported for further processing. In this context, reference is made to DE 93 18 410 U1. This patent discloses a stacking column in which the latch levers are equipped with springs that move them from their support position to their catch position or to their rest position when unloaded. In the locking position, transverse stop pins are provided in the tower body to act as rotation stops for the retaining arms of the latch levers. The latch levers are identical, and the support arm and the retaining arm are of the same width and aligned with each other. However, a disadvantage of the stop pins is that, in practice, the circular profile of these stop pins repeatedly causes them to break, bend, or cause the latch levers to bend under heavy loads and the acceleration forces that occur during transport. A similar design is also shown in DE 29 30 053 A1. There, circular bearing bolts are also used, which are only inserted into corresponding side walls as needed to provide support, and again only in the rear area of ​​the latch. Here too, high weights lead to the disadvantages described above. Reference is further made to DE 298 08 971 U1, which provides for a shock-absorbing and elastic material made of plastic or rubber on the latch levers themselves in order to absorb the resulting forces. This is not feasible for heavy loads weighing several hundred kilograms up to several tons, as the amount of shock-absorbing material made of plastic or rubber would be far too large to actually secure such a heavy load, for example, during transport. There are vertical stacking columns, but also horizontal or inclined ones, which are likewise subject to the present invention. For loading such stacking columns, latches have proven very practical. These latches are connected in such a way that they move from a rest position to a working position when the stacking column or rack is filled with these stacking columns. This process usually begins by placing a workpiece on the bottom latch, which rotates the bottom latch into the working position. This rotation causes the bottom latch to move the next latch into a ready position, where it can receive the next item. Upon receiving the next item, the following latch is again rotated into the ready position. Outside of the ready and working positions, the latches are in a rest position, for example, between two side plates of the stacking column. Such a stacking column is described, for example, in DE 20 2020 104 669 U1. Reference is further made to DE 196 41 270 A1, which discloses a device for stacking and transporting molded parts, in particular body panels, comprising at least two stacking columns with a U-shaped cross-section. Each stacking column is equipped with superimposed latch levers, each carrying control and support arms and mounted about transverse axes. When a lower support arm is moved into a working position projecting from the stacking column, the next higher support arm moves into a standby position, while the support arms above remain in their rest positions within the U-shaped stacking column. If the support arms have an upward profile due to the special design of the molded parts to be received, the front sections of the support arms are designed to interlock positively in the rest position of the latch levers. Reference is also made to WO 2007 / 027 059 A1, which describes a stacking column for components comprising a vertical component with a front opening mounted on a support plate. Mounting brackets are provided on the inner surfaces of the side walls of the vertical component, in which pivotally mounted bars are arranged, each bar having a rectangular load-bearing area at its front end. The bars are mounted in the brackets via projections formed at their ends and coupled to cams via angled sections at their rear ends, enabling sequential actuation of the bars. Additionally, each bar is associated with an elastic element that provides a restoring force. Finally, reference is made to DE 20 2005 005 582 U1, which describes a stacking column for storing transport and storage goods arranged one above the other or side by side, in which several latches are pivotably mounted in the column. Two adjacent latches are coupled to each other via drive elements that have a guide in which a drive element attached to each latch is movably guided, resulting in coupled movement of the latches. In the working positions of the latches, the drive elements bear against a contour of the front of the stacking column, thereby defining and stabilizing the respective working position of the latches. Object of the invention The object of the present invention is to overcome the disadvantages of the prior art. In particular, a stacking column is to be provided that can accommodate as many bearing parts as possible in a single stacking column. The necessary clearances within the stacking column for loading and unloading are to be optimally utilized. Solution to the task The features according to claim 1 lead to the solution of the problem. Advantageous embodiments are described in the dependent claims. A stacking column according to the invention serves to hold bearing components on a stacking latch, wherein a base body consists of two side walls connected to each other via a back wall. These side walls are key elements of the construction and serve to stabilize the entire stacking column. The connection via the back wall ensures increased rigidity and strength of the construction, particularly when the stacking column is subjected to high loads. The two side walls, together with the back wall, form a channel shape specifically designed to hold the stacking latches. This arrangement allows for a space-saving yet stable mounting of several stacking latches, which are pivotably arranged one above the other. The channel shape also offers the advantage that the stacking latches can be guided securely and in an orderly manner without jamming or tilting. In the preferred embodiment, the bearing parts are body parts for motor vehicles or trucks, or other bulky components or the like. Each stacking latch consists of a guide cage and a receiving tongue. The guide cage provides stable support and guidance for the latch within the stacking column. The receiving tongue is geometrically designed to securely hold the components. The combination of guide cage and receiving tongue ensures that tensile and compressive forces are distributed evenly. This prevents the stacking latches from deforming or breaking, even under high loads. The components are securely held in the stacking latch, ensuring a structured arrangement. This structure facilitates loading and unloading, as the components remain easily accessible. Furthermore, the precise guidance of the stacking latches contributes to even load distribution, reducing stress on individual components. The combination of guide basket and receiving tongue achieves optimized load distribution, preventing point overload and thus significantly extending the service life of the stacking latches. The stacking latches are loaded sequentially. A unique feature is that the first loaded latch starts from a ready position. Once the first latch is loaded with the storage component, a linkage pulls the second latch from its rest position into its ready position. This moves the first latch from its ready position into its working position. As soon as the second latch is loaded, the third latch, which follows functionally, is pulled from its rest position into its ready position, thereby pushing the second latch into its working position. As described above, the stacking latches each consist of a guide basket and a receiving tongue. The guide basket, in turn, comprises a base and two wings arranged at right angles to it. Each of these wings is equipped with a bore for an axle bolt and another bore for a linkage bolt. The axle bolt is rotatably mounted between the two side plates and in bores in the side plates. A return spring is arranged around the axle bolt, the first spring leg of which presses against the rear wall of the stacking column. The second spring leg is positioned to push the linkage bolt back into a rest position. The linkage bolt is movably guided within an arc-shaped slot, the base of which is recessed into one of the side walls of the stacking column. The linkage also engages the linkage bolt to achieve the functionality of rest, ready, and working positions described above. In this way, the stacking latches are operatively connected to each other via the linkage bolt. The linkage allows the next stacking latch to be moved into the ready position when one latch reaches the working position. As soon as the next stacking latch also reaches the working position, the following stacking latch is pivoted into the ready position. The receiving tongue of the stacking latch is equipped with a positioning plate. This positioning plate points from the receiving tongue of the stacking latch towards the functionally separate stacking latch. In the ready and / or working position, the positioning plate protrudes from the two side walls of the stacking column, where it is mounted on the receiving tongue of the stacking latch. This has the advantage of reducing the space required for the stored part in the working position of the stacking latch compared to when loading. For example, during loading, a clearance of 0.8 cm to 1 cm is required between the stored part and the guide angle of the stacking column, whereas in the working position, a clearance of 0.4 cm is sufficient. This allows more parts to be stacked on top of each other in the same stacking column than would be possible without the positioning plate. The positioning plate can be arranged in different ways depending on the requirements. It can be inclined towards the guide basket on the receiving tongue. Alternatively, the positioning plate can be inclined away from the guide basket or arranged at a right angle to the receiving tongue. This means that the positioning plate can be welded, bolted, or riveted to the receiving tongue as a strip of sheet metal. The positioning plate can also be a metal part cut from the stacking latch along two or three edges and folded open along the last edge. In another embodiment, the positioning plate can also form a connecting strip to the guide basket. This connecting strip is riveted or welded to the guide basket using the stacking latch. Although other connection methods are conceivable, these methods have proven particularly practical. The connecting strip in the guide basket allows for simple and cost-effective manufacturing. In a preferred embodiment, the connecting strip and the positioning plate are formed in one piece. In this embodiment, a rivet recess is located in the connecting strip. In another embodiment, the rivet recess can extend over both the connecting strip and the positioning plate. In this case, both the connecting strip and the positioning plate have a rivet recess. This rivet recess can be located either on the connecting strip or on the positioning plate itself. Preferably, however, the rivet recess is located in the transition area between the connecting strip and the positioning plate.This has the advantage that a rivet protruding from the guide basket of the second stacking latch, which connects the positioning plate's connecting strip, can cause problems in the rest position if the rivet of the third stacking latch protrudes into the rest position of the second stacking latch and unintentionally pushes the connecting strip / positioning plate away. This can be prevented by the rivet recess, as in such a case the rivet of the third stacking latch moves into the rivet recess of the second stacking latch. This allows the distance between the stacking latches to be reduced. The positioning plate has a first width that is greater than the width of the receiving tongue. It forms two adjustment fingers that flank the receiving tongue and point away from the functionally wider stacking latch. At least one of the side walls is equipped with a guide angle that projects perpendicularly from the side wall. The positioning plate of the stacking latch's receiving tongue extends beyond the longitudinal extent of this guide angle in the ready and / or working positions. In this way, the positioning plate serves as a boundary for the bearing component mounted on the stacking latch. The longitudinal extent is defined as the imaginary extension of the guide angle across both side walls of the stacking column. Character description Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings; these show in: Fig. 1 a sectional side view of a stacking column according to the present invention along line I - I in Fig. 3; Fig. 2 a perspective view of several stacking latches arranged one above the other; and Fig. 3 a top view of the stacking column according to Fig. 1. Example of implementation According to Figures 1, 2 to 3, a stacking column S has several stacking latches 1, 1.1, 1.2 for receiving bearing parts 25. The stacking column S has a base body 2, which consists of two side walls 3, 4 connected to each other via a back wall 5. The two side walls 3, 4 form a channel shape with the back wall 5, and the stacking latches 1, 1.1, 1.2 are pivotably arranged one above the other between the two side walls 3, 4 in the channel shape. The stacking latches 1, 1.1, 1.2 each consist of a guide basket 10 and a receiving tongue 11. The guide basket 10 in turn consists of a base section 20 and two wings 21 arranged at right angles to it. The wings 21 each have an axle bolt bore 22 for an axle bolt 6 and a linkage bolt bore 23 for a linkage bolt 7. The axle bolt 6 is rotatably mounted between the two side walls 3, 4 and in bores 9 in the side walls 3, 4. A return spring 17 is arranged around the axle bolt 6, the first spring leg 18 of which presses against the rear wall 5 of the stacking column S and the second spring leg 19 of which is arranged to press the linkage bolt 7 into a rest position. The linkage bolt 7 is movably guided within two arc-shaped elongated holes 8, which are provided in the side plate 4 and in a linkage 24, respectively, so that the stacking pawls 1, 1.1, 1.2 are operatively connected to each other via the linkage 24, acting on the linkage bolt 7. The linkage 24 acts such that when one stacking pawl 1 reaches a working position, the other stacking pawl 1.1 is moved into a ready position. As soon as this other stacking pawl 1.1 also reaches a working position, the other stacking pawl 1.2 is again pivoted into the ready position. The receiving tongue 11 of the stacking latch 1, 1.1, 1.2 has a positioning plate 12, which points from the receiving tongue 11 of the stacking latch 1, 1.1, 1.2 towards the functionally further stacking latch 1, 1.1, 1.2. In the ready position and / or working position, the positioning plate 12 projects from the two side plates 3, 4 of the stacking column S on the receiving tongue 11 of the stacking latch 1, 1.1, 1.2. The positioning plate 12 can be arranged inclined towards the guide basket 10 on the receiving tongue 11 of the stacking latch 1, 1.1, 1.2. However, the positioning plate 12 can also be arranged inclined away from the guide basket 10 on the receiving tongue 11, or at a right angle to the receiving tongue 11. The positioning plate 12 forms a connecting strip 13 to the guide basket 10, wherein the connecting strip 13 is riveted, screwed, or welded to the guide basket 10 by means of the stacking latch 1, 1.1, 1.2. Other connections are conceivable, but generally not practical. The connecting strip 13 and / or the positioning plate 12 have a single rivet recess 14. This means that either the connecting strip 13 or the positioning plate 12 has the rivet recess 14. Preferably, however, the rivet recess 14 is arranged in a transition area between the connecting strip 13 and the positioning plate 12. An advantage of this design is that a rivet 26, which rivets the connecting strip 13 of the positioning plate 12 into the guide basket 10 of the stacking latch 1.1, can enter this rivet recess 14 when the stacking latches 1, 1.1, 1.2 are in their rest position. In this way, the stacking latches 1, 1.1, 1.2 can have a smaller distance between them. The positioning plate 12 further has a first width that is larger than a second width of the receiving tongue 11, wherein the positioning plate 12 forms two adjustment fingers 15 flanking the receiving tongue 11 away from the functionally further stacking latch 1, 1.1, 1.2. The side wall 4 has a guide angle 16 which projects from the side wall 4 at a right angle. The positioning plate 12 of the receiving tongue 11 of the stacking latches 1, 1.1, 1.2 projects beyond a longitudinal extent of this guide angle 16 in the ready position and / or working position. The positioning plate 12 thus advantageously serves as a limit for the bearing part 25 to be arranged on the stacking latch 1, 1.1, 1.2.
