Description

Technical field

[0001] The invention relates to a stacking column for receiving bearing parts according to the preamble of claim 1. State of the art

[0002] Such stacking columns, or latches integrated within them, are known, for example, from DE 38 11 310 C2. They are usually vertical stacking columns arranged in a square. However, for technical reasons, it can also be advisable to arrange these stacking columns at an angle, as shown in DE 41 33 464 A1. Furthermore, there is also the possibility of arranging the stacking column horizontally, for example, according to DE 40 20 864 A1.

[0003] In all these stacking columns, the stored goods rest in or on the support arms of latch levers, creating a risk of shifting. This disadvantage is particularly problematic when the stacking columns are designed to be transportable. Furthermore, shifting on the support arms can damage the stored goods. Therefore, efforts are made to additionally secure the stored goods on the stacking columns. According to DE 196 47 578 A1, this can be achieved by providing an intermediate latch between two adjacent latch levers. After the stored goods have been placed on or against one latch lever, this intermediate latch can be engaged or disengaged by pivoting another latch lever on the opposite side of the first latch lever.

[0004] In this context, reference is made to DE 20 2006 005 086 U1. This patent describes a stacking column for storing or transporting goods, comprising a side wall and several latch levers. The latch levers have transverse bolts that engage in recesses in the side wall, limiting the possible pivoting movements of the latch levers. The recesses feature special undercuts in the area of ​​the latch levers' ready position. In this ready position, the transverse bolts, under preload, engage in the undercuts. This ensures a secure and stable positioning of the latch levers in their ready position.

[0005] Reference is also made to ES 2 992 810 A1. This patent discloses a stacking column in which parts are placed on pivoting latches. These latches can assume three positions: a folded position within the structure, a waiting position with lateral projection, and a support position for securely carrying the part. The latches are connected in pairs, so that the movement of one latch automatically moves the one above it into a predetermined position. At least one of the latches also has an automatic locking and unlocking system, which is actuated by a cam rotatable about a parallel axis. When the part is lifted, for example by a robot, the cam is automatically activated and moves from the locked position to the retracted position.This unlocks the relevant latch and allows it to return to the waiting position independently, enabling a safe and automated charging and unloading process.

[0006] Furthermore, many stacking columns are designed so that the successive clinics are connected to each other via a linkage, making their movement interdependent. In the working position, these clinics are then held only by the linkage or the stored goods. Object of the invention

[0007] The object of the present invention is to provide a stacking column for receiving stored goods, in which more than one stored item can be placed on a single stacking latch and this can be done in a possibly multi-stage i.e. successive loading, without the stacking latch pivoting from the ready position for loading into the working position as an indication of complete loading as soon as the first stored item is placed, but remaining in the ready position until a defined number of stored goods presses on the stacking latch. Solution to the task

[0008] The features according to claim 1 lead to the solution of the problem. Advantageous embodiments are described in the dependent claims.

[0009] The stacking column for holding stored goods on a single stacking latch is designed so that the latch moves from a rest position to a ready position. To place stored goods on top of or next to each other at defined intervals on a single stacking latch, multiple stacking latches are used, arranged either one above the other or side by side. These stacking latches are pivotally mounted within the channel between the two side walls.

[0010] The stacking latches are connected to each other via a linkage that engages the linkage pin. This linkage controls the movement of each stacking latch: as soon as a stacking latch reaches its working position, i.e., is loaded, the adjacent stacking latch is moved from its rest position to its ready position. The ready position indicates the state in which the stacking latch is prepared for the next item to be stored.

[0011] The stacking latches are moved via the linkage, which controls their position between rest, ready, and working positions. The linkage is connected to the linkage bolt. The first, or bottom, stacking latch is an exception, as it is generally not in a rest position but only moves between the ready and working positions. It is located directly on the base plate and always remains in one of these two positions. In cases where there is no base plate, the first stacking latch is the one to be loaded first.

[0012] Previously, it was standard practice to place stored goods onto a stacking hook in a single loading operation. Multi-stage loading, where several items were placed successively onto a single stacking hook, was not possible. However, this was not the most efficient approach, as in practice, stored goods are often produced sequentially or removed from a production machine and then placed.

[0013] The stacking column according to the invention now enables a multi-stage loading process. This allows a predetermined number of identical goods to be placed on a single stacking latch. Additionally, it is also possible, for example, to place different goods on a single stacking latch.

[0014] The stacking column consists of a base with two side panels connected by a back panel. The stacking latches are rotatably mounted between the two side panels on an axle bolt. These side panels, together with the back panel, form a trough shape, which can optionally include a base plate. The base plate can be attached to a surface, such as the floor of a factory hall, a storage cart, or a pallet.

[0015] Each stacking latch has a linkage pin that is movable within a straight or curved slot in the side plate. This mobilizes the stacking latch and simultaneously provides its attachment point for the linkage that controls the movement between the ready and working positions. In the described embodiment, the linkage pin is guided within two curved slots, each of which is recessed into the side plates. The pivot pin, in turn, is mounted between the side plates and rotates within corresponding bores.

[0016] To return the stacking latch to its resting position, a return spring is arranged around the axle bolt. Its first spring arm pushes against the rear wall, while its second spring arm returns the linkage bolt to its rest position. This means that the return spring uses its force to push the stacking latch into its rest position, while the weight of the stored goods exerts an opposing force on the stacking latch.

[0017] In addition to a linkage bolt, each stacking latch also has an axle bolt. These bolts are not part of the stacking latch itself, but serve its function.

[0018] A key innovation of the invention is the use of a radial spring connecting the linkage pin to the axle pin. This radial spring pulls the linkage pin towards the axle pin and simultaneously ensures that the linkage pin is constantly pressed against the inner contour of the bow's elongated holes. This enables controlled movement of the linkage pin and thus also of the stacking pawl. Crucially, the inner contour between the rest position and the working position of the linkage pin features a bead to overcome the bead. One possible embodiment of this bead is a raised projection extending away from the axle pin. Alternatively, it can be a step that divides the inner contour into two sections: a first section extending from the rest position to the bead, and a second section extending from the bead to the working position.For example, the first section might run closer to the axle bolt, while the second section rises and runs further away from the axle bolt. Additionally, it could be a recess or recess pocket into which the linkage bolt enters towards the axle bolt and, after overcoming the ridge, exits again. Combinations of these are also possible.

[0019] This overcoming ridge interrupts the arc-shaped contour of the inner surface and enables multi-stage loading of the stacking latch. In combination with the radial spring, which constantly presses the linkage pin against the inner surface, the overcoming ridge acts as an obstacle to be overcome. This obstacle is overcome as soon as a defined load acts on the stacking latch. However, an overcoming ridge is also defined as a recessed pocket extending towards the axle pin between the rest position and the working position. In this recess, the linkage pin enters the ready position, pauses briefly, and then moves into the working position after the stacking latch has been sufficiently loaded.

[0020] The multi-stage loading process is achieved by ensuring that the obstacle of the overcoming ridge is only overcome once the predetermined weight of the stored goods has been reached. Only when the force exerted on the stacking latch exceeds the defined force of the radial spring does the linkage bolt slide over the overcoming ridge and change from the ready position to the working position. Simultaneously, the next stacking latch is moved from its rest position to the ready position.

[0021] The overcoming bead is arranged within the inner contour between a rest position recess and a working position recess.

[0022] In an alternative embodiment, the second spring leg of the return spring can protrude between the linkage bolt and the stacking pawl.

[0023] This profile corresponds to the typical pattern of an arc-shaped slot and thus also to the inner contour. However, it is interrupted by the override bead, which has a larger radial distance to the bore of the axle bolt. Apart from the override bead, the inner contour can have a basic radial distance of 15 mm to 85 mm. This allows the operator to determine, depending on the distance, how much weight is required to guide the linkage bolt over the override bead. A larger distance requires greater force and therefore a heavier load.

[0024] Additionally, the force required to overcome the overcoming ridge can be adjusted by using multiple radial springs. A further radial spring can be present, which, together with the first radial spring, flanks the return spring at the ends of the axle bolt. This ensures an even distribution of force and prevents long-term one-sided stress on the axle bolt or the linkage bolt.

[0025] Furthermore, in addition to an overcoming ridge, further overcoming ridges can be formed on the inner contour. This gives the operator the ability to precisely calculate and control multi-stage loading processes.

[0026] A stacking latch according to the invention consists of a bearing arm and a guide receptacle. The guide receptacle comprises a base section and two right-angled wings, each having two axle bolt bores and two guide bolt elongated holes. In addition, two guide bolt elongated holes can be formed parallel to a bend in the base section that transitions to the wings. The bearing arm can also be provided with an additional plastic coating. Character description

[0027] 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. Figure 1 shows a stacked column (S) in perspective from a first perspective from an oblique angle above; Fig. Figure 2 shows the stacking halls (S) from the Fig. 1 from a second perspective from a slightly elevated angle; Fig. Figure 3 shows a partial view of the stacked column (S) from a first perspective; Fig. 4 shows the partial view of the Fig. 3 from a second perspective; Fig. Figure 5 shows a simple side view of one of the side cheeks without any other components; Fig. 6 shows the view from the Fig. 5 with additional components in a rest position of the stacking latch (S); Fig. 7 shows the view from the Fig. 5 with additional components in a ready position of the stacking latch; Fig. 8 shows the view from the Fig. 5 with additional components in a working position of the stacking latch;

[0028] The Fig. Figure 1 shows a stacking column S in perspective from a first oblique angle above. The stacking column S serves to hold bearing parts on a stacking latch 1. The stacking column S primarily consists of a base body 2, which in turn comprises a first side wall 3 and a second side wall 4. At one end, the base body 2 has a bottom plate 15. At the other end, the base body 2 is closed off with a cover plate 17. The base body 2 forms a trough shape in which several stacking latches 1 are arranged one above the other. The first stacking latch 1 near the bottom plate 15 is in the working position. The stacking latch 1 above it, towards the cover plate 17, is in the ready position. The remaining stacking latches 1 are in the rest position. Since the inside of the first side wall 3 is partially shown in the first perspective, a linkage 20 and the first curved elongated holes 8.1 are visible there.The first arc slots 8.1 are recessed into the first side cheek 3.

[0029] The linkage 20 connects the stacking latches 1 arranged in the base body 20 in such a way that whenever the first stacking latch 1 moves, the adjacent second stacking latch 1 is activated. This occurs in the sequence from rest position to ready position to working position and back. The only exception to this is the stacking latch 1 nearest to the base plate 15, which is not in the rest position in its initial position, but already in the ready position, and only returns to this ready position.

[0030] Fig. 2 shows the stacking halls S from the Fig. 1. From a second perspective, from a slightly elevated angle. The one leading up to... Fig. The statements made in point 1 also apply to this. Fig. 2. From this perspective, the inside of the base body 2 is partially visible. Consequently, the second arc-shaped elongated holes 8.2, which are recessed into the second side wall 4, are also visible.

[0031] The Fig. Figure 3 shows a partial perspective view of the stacking column S according to the invention. In the Fig. The stacking latch shown in the 3rd stacking latch 1 is the next stacking latch 1 of the base plate 15.

[0032] The stacking latch 1 is arranged within the channel shape of the base body 2. The base body 2 primarily consists of the two side walls 3, 4, which are connected to each other via a back wall 5. Further stacking latches 1, not shown, are also arranged between the two side walls 3, 4 in the channel shape, either one above the other or next to each other, and are pivotably positioned.

[0033] The stacking latch 1 is assigned an axle bolt 6 and a linkage bolt 7.

[0034] The linkage bolt 7 is movably guided within the two curved elongated holes 8.1, 8.2. These curved elongated holes 8.1, 8.2 are each recessed into one of the side plates 3, 4. Specifically, the first curved elongated hole 8.1 is recessed into the first side plate 3. The second curved elongated hole 8.2 is recessed into the second side plate 4.

[0035] The axle bolt 6 is arranged between the two side plates 3, 4 and rotatably mounted in bores 9.1, 9.2 of the side plates 3, 4. The first bore 9.1 is located in the first side plate 3 and the second bore 9.2 is located in the second side plate 4.

[0036] A return spring 10 is arranged around the axle bolt 6. A first shock absorber 11.1 presses against the rear wall 5. A second shock absorber 11.2 is arranged in such a way that it pushes the linkage bolt 7 towards a rest position.

[0037] Furthermore, radial springs 12, 19 are shown, which connect the linkage bolt 7 and the axle bolt 6.

[0038] The radial spring 12 and the further radial spring 19 are arranged such that they pull the linkage bolt 7 towards the axle bolt 6. In the embodiment shown here, the radial spring 12 and the further radial spring 19 are arranged such that they flank the return spring 10 on the axle bolt 6 at their respective ends.

[0039] The radial springs 12 shown pull the linkage bolt 7 against an inner contour 13.1, 13.2 of the arc-shaped elongated holes 8.1, 8.2, which points towards the axle bolt 6. In detail, the first inner contour 13.1 is part of the first arc-shaped elongated hole 8.1 and the second inner contour 13.2 is part of the second arc-shaped elongated hole 8.2.

[0040] The statements made here also apply to the other stacking pawls 1 located in the stacking column S, wherein the other stacking pawls 1 are moved in arc-shaped elongated holes 8.1, 8.2 which have an overcoming bead 16.

[0041] Figures three to six clearly show that the inner contour 13.1, 13.2 runs between the rest position and the working position of the stacking latch 1. It forms the overcoming bead 16, which projects away from the axle pin 6 and the bores 9.1, 9.2 into which the axle pin 6 engages. Along the stacking latch 1's path from the rest position to the working position, the overcoming bead 16 creates resistance, enabling multi-stage loading of the stacking latch 1 in the ready position.

[0042] In another embodiment (not shown), the overcoming bead 16 of the inner contour 13 is arranged between a rest position recess of the stacking pawl 1 and a working position recess of the stacking pawl 1. The rest position recess and the working position recess are formed as pockets projecting towards the bores 9.1, 9.2 into the respective arc-shaped elongated holes 8.1, 8.2 at their ends, which are intended to make it more difficult for the rod bolt 7 to slide out unintentionally.

[0043] In the Fig. 3 and Fig. Figure 4 clearly shows that the second shock absorber 11.2 projects between the linkage bolt 7 and the stacking pawl 1. It is also clearly visible that the stacking pawls 1, arranged one above the other or next to the other, are operatively connected to each other via a linkage 20, engaging the linkage bolt 7.

[0044] The stacking latch 1 in turn consists of a bearing arm 21 and a guide receptacle 22. The guide receptacle 22 consists in detail of a base area 23 and two right-angled wings 24, wherein the wings 24 have two axle bolt bores 25 and two guide bolt elongated holes 26.

[0045] The two guide pin slots 26 run parallel to a bend 27 that connects the base area 23 with the wings 24. This arrangement ensures precise guidance and stability of the moving components.

[0046] In the Fig. Figure 5 also shows how a radial distance 14 is achieved. The inner contour 13 has a substantially arc-shaped radial distance 14 of 15 mm to 85 mm to the bores 9.1, 9.2 of the axle bolt 6. The inner contour 13 of the arc-shaped elongated hole 8.1 has a predominantly arc-shaped distance of 15 mm to 85 mm to the bore 9.1 of the axle bolt 6. Starting from the bore 6 in the side wall 3, into which the axle bolt 6 engages, the arc-shaped path begins shortly after the 12 o'clock position and ends between the 4 o'clock and 5:30 o'clock positions with respect to this bore 9.1. The same applies, of course, to the opposite side wall 4 and the arc-shaped elongated hole 8.2 and the bore 9.2 located there.

[0047] The Fig. Figure 6 shows the stacking latch 1 in its rest position. The linkage bolt 7 is located near the rear wall 5 and slides counterclockwise in the arc-shaped elongated hole 8.2 towards the ready position, which is in the Fig. Figure 7 shows the movement of the linkage bolt 7 in a defined manner against the inner contour 13. Once the stacking pawl 1 has been loaded according to specifications, the linkage bolt 7 overcomes the overcoming bead 16 against the force of the radial springs 12, 19 and slides into the working position, as shown in the Fig. 8 is shown.
