Abstract

The stacking column has swiveling support plates (20) for the items being stacked. Latches (40) at the pivot ends of the plates allow them to be coupled together.

Description

The The present invention relates to a stacking column for stacking arranged storage of transport and / or stored goods swiveling in the column stored pawls.

Latch columns or stacking columns are suitable for damage-free Storage and transportation of storage or transport items, eg. of sheet metal parts. In the production of sheet metal parts such as Body components are these after the deformation process means Handling devices (eg. Robots) taken from a thermoforming tool and ready for it stored and stacked standing metal pallets, such a Pallet typically has at least two stacking columns. Depending on the shape and size of the moldings can on the range, however, up to twelve Stack columns grouped be. Every stacking column has several pivotable pawls, one above the other or side by side are arranged.

The EP 0 945 371 A2 describes a stacking column, the pivotable pawls each having a support arm and a control arm, wherein the control arm of each pawl is arranged offset from the support arm. DE 42 30 953 A1 describes a stacking column, in which the pawls each have a counterweight, which ensures that the pawls in the unloaded state from a working position to a rest position. The pawls are each interconnected with a linkage, so that when a pawl is in working position, the respective adjacent pawl is pivoted to a standby position.

at Most known stacking columns are all latches in the manner described coupled together, so that, for example, at a located in working position latch the adjacent latch in the ready position and the next latch in Rest position is located. However, the same with a single stacking column Parts are transported in different stages of production can, So it may be necessary that the stacking column for parts of different thickness must be suitable. So can a part after welding another Parts a greater thickness so that it no longer fits in the simple division of the stacking column. Such a case occurs, for example, in the production of body roofs of Vehicles on during their Production supplemented or extended by attachments. For space economic reasons is it does not make sense to divide (i.e., the spacing of the adjacent ones) usable pawls from each other) to choose from the outset so large that the parts are still transportable in their last processing stage are. Also the use of different pallets with different designed stacking columns is common in the manufacturing process not economical implemented.

One The aim of the present invention is to provide a generic stacking column for disposal to make a change the division of the usable pawls is easily possible, to differently procured, in particular different thickness, Store parts in the same stacking column or to be able to transport.

This The aim of the invention is the subject of the independent protection claim reached. Features of advantageous developments of the invention result from the dependent ones Claims.

The The present invention relates to a stacking column for stacking arranged storage of transport and / or stored goods swiveling in the column mounted ratchet levers, the aligned one above the other and largely evenly spaced from each other in the column are mounted, each having a support portion and a driver portion between which the storage is located in the column, and pivotable between a working position and a rest position are. According to the present invention It is provided that at least two adjacent pivotable ratchet levers by means of a detachable Coupling element are connected to each other in such a way that in each case at least two adjacent pivotable latch lever one each perform parallel pivoting or in each case in a parallel position (working position, readiness position or Rest position) can be brought.

The pawls of generic stacking columns each have a support section and a driver section. Each pawl lever has an axis between the support portion and the driver portion, on which it is pivotally mounted in the stacking column. In a common embodiment of stacking columns is in each case a lowermost, not loaded latch in the ready position or preparation position. The ready position of the pawl is characterized in that its Tragab section with the longitudinal direction of the column includes an acute or obtuse angle, wherein the support portion protrudes so far beyond an outline edge of the column that a storage or transport goods can be stored thereon. By placing a storage or transport goods on the support portion of the pawl, this pawl is pivoted down into a working position or end position. In the working position of the support portion of the pawl is aligned substantially perpendicular to the longitudinal direction of the column. The pivoting action of the pawl causes the adjacent pawl to be placed in the ready position. Each further over arranged pawls are meanwhile still in rest position. The rest position of a pawl is characterized in that its supporting portion encloses an acute angle with the longitudinal direction of the column; the support section is thus not ready for placing a Guts. Usually, the pivoting movements of the individual pawls are guided over laterally arranged on the pawls and engaging in guide slots on the stacking column guide pins.

The Coupling of the swiveling operations from directly adjacent latches in such a way that a panning a pawl from the standby to the working position panning causes the directly adjacent pawl from the rest position to the ready position, can be done through different mechanisms, some of which in the present specification and in each case in connection with the mechanisms for the coupling of remote invention Latches closer to be discribed.

In a usual stacking column functioning as described carries each one Pause the pivoting movements individually. Therefore, it is possible in such a stack stack one of the number of pawls corresponding number of goods lay down. One speaks of a single division of the stacking column.

According to the present Invention it is possible the simple division of a stacking column to convert easily into a double or multiple division, by depending on the embodiment two or more adjacent latches if necessary in a way be connected to each other two or as needed more adjacent pawls perform all pivotal movements together. The Swiveling a pawl from the ready position to the working position has the consequence that not the directly adjacent, but the next but one or an even further pawl goes into ready position.

This On the one hand can happen in such a way that the pivoting of a Latch from the ready position to the working position the common and parallel panning of two or more, respectively neighboring pawls from the rest position to the preparation position entails. Alternatively, the pivoting of a latch from the ready position in the working position the joint and parallel panning of two or more, each adjacent pawls from the rest position into the working position, with the panning of the top of these pawls in the working position in the usual way pivoting the turn directly adjacent pawl from the rest position effected in the preparation position.

In both cases is only the support section of the top of the common Pivoting action involved pawl for a hang-up or stored goods accessible. Those latches between the pawl triggering the movement and the top of the interlocking pawls, are by for the depositing of goods not usable. Therefore enlarge the pitches the usable pawls to the 2-fold or n-fold.

The Connection of two or more adjacent latches takes place according to the invention by a solvable Coupling element, through which the coupled latch lever one each perform common parallel pivoting or each in a parallel Position (working position, standby position or rest position) can be brought.

A Embodiment of the invention provides that the releasable coupling element is formed by at least one locking lever which is pivotable is attached to a latch lever and with at least one Locking element on at least one adjacent latch lever is connectable.

When Lock lever is in this context a component denotes a hook structure, driving nose or other Having structure capable of having a locking element to lock or otherwise effectively attack on this.

When Locking element is a structure in the present context referred to, which is arranged on a pawl that they for the effective On or engagement of a locking lever is suitable.

Prefers have several latch lever a stacking column such locking lever on. Particularly preferred are the latch lever of a stacking column, the Have locking lever, regularly distributed over the stacking column (For example, every second or every third pawl has a locking lever on) to a regular division the stacking column to reach. The locking levers are preferred in the field of guide pins arranged on the ratchet levers.

Those pawls, which carry the locking elements on which the locking levers can attack, do not carry any locking levers themselves. In particular, the guide pins, which are mounted laterally on the pawls and engage in guide slots in the column jacket, be made so long that they are out of the Projecting pillar and can serve as points of attack for the locking lever.

locking lever and locking elements can each arranged on only one or both sides of the latch lever be. You can each inside the column mantle or outside of column jacket be arranged.

Especially Preferably, every second or every third pawl lever has locking levers on, each with on directly adjacent and / or the next but one latch lever arranged locking elements are brought into engagement can.

The Locking lever can there - like the Guide pins - either on the support portion of the latch lever or on the driver portion of the Be arranged latch lever.

are the locking lever on the driver portion of the latch lever arranged, then they are behind the pivot axis of the ratchet lever. at a pivoting of the ratchet lever from the standby position in the working position, the attack points of at least a locking lever on the ratchet levers upwards. Consequently may be a latch lever whose locking element from above with a locking lever on a ratchet lever arranged above it is engaged in a swing from the rest to the ready position the above involve him lying pawl element in his movement. The driver section of the overhead pawl lever is thereby pressed up, so that its support section just in case is in the ready position. Just like that can a latch lever, the locking lever from below with a locking element on a ratchet lever arranged above it is engaged in a swing from the rest to the ready position the driver section of the over Press him lying pawl element with upwards and so the latch lever bring into ready position.

are the locking levers are arranged on the support section of the latch levers, then they lie in front of the pivot axis of the ratchet lever. When panning of the ratchet lever from the standby position to the working position move the attack points of at least one locking lever at the ratchet levers down. In this case, it is beneficial when the locking lever is designed as a driving nose and engages a locking element of a ratchet lever, which is above the Latch lever is located on which the driving lug is attached. On this way, a ratchet lever when pivoting from the rest in the standby position over involve him lying pawl element in his movement by he over the with him lying down pawl lever pulls down so that its Carrying section also goes into standby position. However, it is also conceivable that the locking lever in such a Arrangement hook-shaped are; also an attack of locking levers from above to locking elements at below arranged ratchet levers is possible.

preferred embodiments the invention provide that the pivotable locking lever independently of how they are shaped, regardless of where at the latch lever they attack, and regardless of whether they are at above or attack on below ratchet levers, together over the Can be operated together with a coupling rod.

The Coupling rod can be arranged in particular on a rear side of the stacking column be, with its longitudinal direction preferably parallel to the longitudinal direction the pillar and is slidable along to this. According to the invention causes a displacement of the coupling rod pivoting the locking lever and thereby, depending on the given arrangement and displacement direction the coupling rod, an intervention of the locking lever on or a release the locking lever of the locking elements.

There also a pivoting of the latch lever an upward or downward movement the points of attack of the locking lever and thus the locking lever itself has the consequence, it is to preserve the pivoting of the Ratchet lever necessary, the connection of the locking lever with to make the coupling rod flexible. For example. can the swiveling the ratchet lever can be secured by the locking levers horizontally and vertically to the coupling rod slidably connected thereto are. For example. the locking lever can be largely L-shaped be, with one of the two L-leg a hook for Locking with the locking element of an adjacent latch lever wearing, in the bend area, the pivotal connection with the latch lever takes place and the other L-leg to the rear in the direction of coupling rod points, being in an oblong Slot engages in the coupling rod or through it attacks. During a movement of the coupling rod up or after presses down or pulls the lower or upper edge of the slot of the coupling rod against the projecting through them leg of the L-shaped locking lever and causes its rotation about its pivot axis. The panning of the associated Ratchet lever leads to a horizontal and vertical movement of the locking lever leg inside the slot in the coupling rod.

In an alternative embodiment The invention may include connecting the at least one locking lever with the at least one locking element by means of a transverse to the longitudinal direction the column slidable coupling rod done. In this case, the connecting the preferably bow-shaped locking lever by pressing take the coupling rod against the stacking column. To the preservation the pivoting of the latch lever is the coupling or push rod not firmly connected to the locking levers: The coupling or Push rod can, for example, hanging freely at the top of the stacking column be attached and act only as a common pressure transducer, no firm mechanical connection with the locking levers must exist.

In an alternative embodiment of the invention the ratchet lever over a number of coupling rods directly connected to each other. In this case, the coupling rods are pivotally laterally to the Ratchet levers, for example. At outstanding from the stack columns, of the Ratchet lever outgoing guide pins attached.

For a simple division the tie rods are so long that they each have the guide pins connect adjacent ratchet lever.

For a two- or multiple division, the coupling rods are correspondingly longer, so that they each pivot with their end portions on the guide pins remote ratchet lever can be attached.

Prefers are the tie rods over at their respective end portions arranged breakthroughs the guide pins plugged in, with the breakthroughs, which are attached to the upper pawl lever pins be, have a long-stretched shape. The guide pins are preferably arranged on the driver part of the ratchet lever. When the ratchet lever is swiveled from the idle mode to the standby mode or from the standby position to the working position the guide pins thus upwards. The on the guide pins Press attached coupling rods Thus, each attached to the other end latch lever pins to the top, to the point where they are in the ready position are located. Due to the elongated shape of the upper opening on the coupling rod is the further movement of the ratchet lever into its working position by loading the support section allows wherein the case taking place movement of the coupling rod the next, with this coupling rod connected ratchet lever in the ready position suppressed. Possibly intermediate ratchet lever go in this embodiment the invention directly from the rest in the working position on. These Movement can be arranged either by the action of an appropriately Weight or supported by a spring.

For a convertibility such a functioning stacking column of the single division to two or more division according to the invention at a Side of the latch column Coupling rods arranged, each with a latch lever with the connect each adjacent and therefore provide the usual single division. On the other side of the latch column, however, longer coupling rods are arranged, depending on the length are suitable for a ratchet lever with the next but one or even further connect remote latch lever. These coupling rods can be "decoupled", that is not communicate with the ratchet levers. In this case works the stacking column with simple division. A connection of the latch lever with the longer coupling rods can be made, for example, by the latch lever slidable Have bolts or bolts are inserted into the pawl lever can, in the breakthroughs the longer one Engage coupling rods and can be effective. For this can For example, within the guide pins guide channels for the bolts be introduced. The guide pins can while still in engagement with the short coupling rods.

In another alternative embodiment the invention may be the stacking column at least one guide rail have, are arranged on the slidable Mitnehmerschlitten. The drivers can at control sections of the latch lever attack. About guided coupling elements can this Driver can be switched so that they each have the pawl the desired Switch on division. Unused latches always stay under the used latches. Preferably, the guide rail at the rear the stacking column arranged; the control sections of the latch levers are located preferably at the back.

The present invention has the advantage that an existing stacking column with different pitch of the latch lever can be used, so that, for example, voluminösere storage or stacking goods can be stored on the stack column, in which case individual latch lever can be put out of service, so that, for example. only every second or every third third of regularly spaced ratchet levers is usable. Allen described embodiments of the invention is common that they work in a released state of the coupling element, for example. When not locking the locking lever with the locking elements or not inserted into the long coupling rods bolt, such as conventional stacking columns, each pawl lever is pivoted individually and to the Stape ment of smaller staple goods can be used.

The Invention will be described below with reference to preferred embodiments explained in more detail with reference to the accompanying figures.

1 to 6 show an embodiment of the stacking column, in which individual latches can be activated or deactivated by means of special locking levers, which are actuated by means of a coupling rod.

7 and 8th show an alternative variant of a stacking column according to the invention, in which a special molded part is used with driving lug.

9 to 12 show a further alternative variant of a stacking column according to the invention with different length coupling rods and slidable bolts.

13 shows a further variant of a stacking column according to the invention with back guide and driving carriage.

The schematic representations of 1 to 6 each illustrate a first variant of a stacking column according to the invention 10 A series of hinged in lateral legs of a U-shaped column section 12 stored ratchet levers 20 ( 201 . 202 . 203 . 204 , ...), so that with the stacking column 10 one of the number of latches 20 appropriate number of transport or storage goods can be stacked on top of each other or side by side. The stacking column 10 Can with a lower edge on a fixed base plate 11 or a metal pallet o. The like. To be anchored. The latch lever 20 each have a support section 22 and a driver or control section 24 on. Between carrying section 22 and driver section 24 or in the area of the driver section 24 are the pawls 20 each in one axis 26 pivotally mounted so that they are between the opposite leg surfaces 14 the U-shaped column section 10 are pivotally mounted.

The latch lever 20 can each be pivoted between a working position, a standby position and a rest position. In its working position, the support section closes 22 an angle between 90 and about 60 degrees with a longitudinal axis of the column 10 a (see eg latch 201 in 2 ). In this position, the support section is used 22 a latch 20 for the storage of storage or transport goods. In a standby position (eg latch 202 in 2 or latch 201 in 1 ) the support section closes 22 with the longitudinal axis of the column 10 prefers an acute angle, while in the rest position (eg pawl 203 in 2 or latch 202 in 1 ) the angle between support section 22 and longitudinal axis of the column 10 even sharper. In the standby position, the support section protrudes 22 a latch 20 so far beyond the inner outline of the column 10 in addition, that a storage or transport goods to be deposited on the support section 22 can capture and press this down when you drop.

The latch lever 20 each have in the range of their Mitnehmerabschnittes 24 at least one guide pin 28 on, each in an arcuate slotted guide 16 can slide in one of the thighs 14 of the column section 12 is arranged.

The scenery tour 16 limits the Verschwenkweg each ratchet lever 20 between his working position and his rest position.

The distance of the pawls 20 each other is dimensioned so that when each at rest adjacent pawls 20 the tops and bottoms of their support sections 22 abut each other. At a reasonable distance is in each case approximately an upper half of an upper side of the support section 22 a lower latch and a lower half of a bottom of the support section 22 an overlying pawl to each other when both pawls are each in the rest position.

1 shows the stacking column, with the first latch 201 is in the ready position or in the preparation position. The remaining latches 202 . 203 , ... are at rest. In the presentation of 2 is the first latch 201 in working or end position. The second latch 202 is in preparatory position while the remaining latches 203 . 204 , ... are at rest. In the presentation of 3 are the first and second pawl 201 and 202 in end position, the third pawl 203 in preparation position and the remaining latches 204 . 205 , ... at rest.

In the illustrated embodiment of the 1 to 6 is every second latch lever 20 a pawl 21 assigned, which is also pivotable between the columnar legs 14 is stored.

ratchets 21 are characterized in that in each case at least one pivotable locking lever 40 is arranged. The locking levers 40 can by pivoting each with locking elements 44 on adjacent latches 20 connected or detached from them.

In the embodiment shown, a locking lever is set 40 from a bow-shaped blocking portion 401 and an angled control section 402 together. The control section 402 surmounted the column to the rear and can with one at the back of the column 10 attached coupling rod 30 interact. The lock section 401 every pawl 21 each has a mouth-like receptacle 403 on that on the locking element 44 in the embodiment shown by the guide pins 28 a ratchet lever 20 is formed, attack and thus the involved latch lever 20 . 21 can connect as soon as the pawl 21 is pivoted in the locked position.

The 1 to 3 illustrate the stacking column 10 with unlocked pawls 21 in which the latches 20 work in a known manner by a pawl 20 brings in working position an adjacent latch in preparation position. In the embodiment shown, this coupling is effected by the shape of the driver sections 24 the pawls 20 ,

The coupling rod 30 is for unlocking the pawls 21 pushed to an upper stop, so that the control sections 402 each pointing upwards at an angle. For the control sections 402 are respectively corresponding slot-like shots or the like on the coupling rod 30 intended. The lock sections 401 as well as their mouth-like recordings 403 are in this unlocked position is not engaged with the corresponding locking elements 44 the pawl lever assigned to them 20 , The latch lever 20 can thus be pivoted in the usual way between their working and standby position and the rest position. In the illustration of the 1 is located at the bottom arranged latch lever 201 in a stand-by position, while all over it ratchet lever 202 . 203 , etc. are in the rest position, where the support sections 22 each within the U-shaped cross section of the column section 12 sunk. In the schematic representation of 2 is the lowest-lying latch lever 201 in his working position, in which his support section 22 is aligned approximately perpendicular to the longitudinal direction of the column. The overlying latch lever 202 is here in his standby position, in which his support section 22 with the longitudinal axis of the column forms an acute angle. The other ratchet levers are in their rest position. In the schematic representation of 3 are the lowest and the second lowest ratchet lever 201 . 202 each in their working position, while the third latch lever from below 203 is in the ready position. The remaining ratchet levers are in the rest position.

In the schematic representations of 4 to 6 is part of the latch lever 20 with their respective associated pawls 21 connected by the coupling rod 30 pushed down, so the control sections 402 the pawls 21 are aligned approximately perpendicular to the longitudinal direction of the column. The with the control sections 402 rigidly connected barrier sections 403 in this case each engage on locking elements 44 the pawl lever assigned to them 20 at. In this way, the respectively interconnected latching levers are functionally coupled together by the connected pawls perform all pivotal movements parallel to each other. For example. caused in 4 respectively. 5 the triggered in the usual way pivoting the latch 202 from the rest to the standby position by pivoting the bottom latch 201 from the standby to the working position a simultaneous pivoting of the third pawl 203 in the ready position. The same occurs in a further pivoting of the second and third latch lever 202 . 203 into the working position. This is the fourth and fifth ratchet lever 204 . 205 each pivoted into the ready position (see. 6 ). In the embodiment shown is a locking option for every second latch lever 20 intended.

The control sections 402 the locking lever 40 pass through slots in the coupling rod in the example shown 30 so that they are movable in both vertical and horizontal directions. This is necessary so that even in the coupled state, a pivoting of the latch lever 20 around its axis 26 is possible.

Basically, any number of pawls 21 be provided, the number of which corresponds at most to the number of existing latches. Thus, for example, every second pawl with a locking lever 40 be provided, as is the case in the embodiment shown.

The 7 and 8th illustrate a second variant of the stacking column according to the invention 10 , in turn, at the back of the column 10 a coupling rod 30 is arranged, by means of which moldings 50 can be actuated or pivoted, optionally in the column jacket 12 inside or - as shown - can be mounted outside. When operated via the guided coupling rod 30 , which in this case may be referred to as a push rod, since it is transverse to the longitudinal direction of the column 10 is shifted, in each case two or alternatively more latches 20 coupled together by each at least one catch nose 52 a molding 50 via a locking element 44 on a neighboring latch 20 pushes.

In the presentation of 7 are the moldings 50 unlocked, so all the pawls 20 after this known standard principle can work. In the presentation of 8th the mold parts are latched, so that in each case a pawl is coupled with an adjacent (or n-higher, depending on the design of the molded part) pawl. Swings the latch 20 which the molding 50 carries, for example, latch 202 in 7 and 8th , from a rest to a standby position, it pulls the adjacent latch 20 , for example, latch 203 in 7 and 8th , with yourself (see 8th ). If two coupled, adjacent pawls are in working position, the next but one pawl is brought into preparation position. Relief of the pawls 20 can be done by gravity, optionally by spring force.

In the variant of the stacking column according to the 9 to 12 are the latch levers 20 over a row from the side of the column 10 arranged coupling rods 31 . 32 directly connected. The coupling rods 31 . 32 are pivoted laterally on the ratchet levers 20 attached by breaking through at their respective end sections 33 by means of which they on guide pins 28 are plugged, that of the Mitnehmerabschnitten 24 the latch lever 20 go out and laterally through guide slots 16 from the stacking column 10 protrude. The breakthroughs 33 on the upper guide pins 28 are attached, thereby have an elongated shape.

When pivoting the support section 22 a ratchet lever 20 around its bearing axis 26 its guide pins move downwards 28 up. The on the guide pins 28 attached coupling rods 31 . 32 thus push the guide pins attached to the other end 28 upwards, and just so far that the corresponding latch lever 20 goes into standby position. Due to the elongated shape of the upper opening 33 on the coupling rod 31 . 32 is the further movement of the ratchet lever 20 in its working position by loading the support section 22 possible, with the case taking place movement of the coupling rod 31 . 32 the next, connected to this coupling rod latch lever 20 presses in ready position.

The 9 and 11 show the stacking column according to the invention 10 in their functional state with individual division. The used coupling rods 31 are designed for this purpose just as long that they each have the guide pins 28 adjacent ratchet lever 20 connect. Thus, for example, has a pivoting of a ratchet lever 202 from the preparatory to the working position result in that the pawl lever 203 goes into preparation position.

10 and 12 show an operating state of the column 10 , in which a double division takes place. These are the coupling rods used 32 correspondingly longer than in 9 respectively. 11 shown so that they each pivotally with their end portions on the guide pins 28 remote ratchet lever are mounted. For example. is the guide pin 28 of the ratchet lever 201 with that of the ratchet lever 203 connected. In this way, for example, has a pivoting of the ratchet lever 201 from the preparatory to the working position result in that the pawl lever 203 goes into preparation position. The intervening latch lever 202 goes in this embodiment of the invention directly from the rest to the working position. This movement can be assisted either by the action of a correspondingly arranged weight or by a spring.

For a convertibility of such a functioning stacking column of the single division to double division according to the invention on one side of the latch column 10 coupling rods 31 arranged, each with a latch lever 20 connect with the respectively adjacent and therefore provide the usual single division. On the other side of the latch column 10 on the other hand are longer coupling rods 32 arranged, which are adapted to a latch lever 20 with the next but one latch lever 20 connect to. These long coupling rods 32 can be "decoupled", that is, not with the ratchet levers 20 communicate as in 9 and 11 shown. In this case, the stacking column works 10 with simple division. A connection of the latch lever 20 with the longer tie rods 32 can be made by the latch lever 20 sliding bolts 46 have or bolts 46 in the latch lever 20 can be inserted into the breakthroughs 33 the longer coupling rods 32 intervene and make them effective. For this purpose, for example, within the guide pins 28 guide channels 47 for the bolts 46 be introduced. The guide pins 28 can continue to engage with the short coupling rods 31 stand as this connection does not interfere with the function of the double division.

In the presentation of 9 are the bolts 46 each at their right stop, so that a single division is realized. Every latch 20 works according to the known standard principle.

In the presentation of 10 it becomes clear that the slidable bolts 46 are shifted to the left and in engagement with the left on the column arranged coupling rods 32 are located. In this way, the mentioned double division is realized, so that in each case over the upper end of the coupling rod 32 operated (nth) latch 20 goes into preparation position. 11 illustrates again in a perspective view, the arrangement of the right side of the pillar 10 located coupling rods 31 , Here, the position is appropriate 9 realized. 12 illustrates again in a perspective view of the arrangement of the left side of the pillar 10 located coupling rods 32 , Here, the position is appropriate 10 realized.

The further variant of the stacking column 10 corresponding 13 has one inside the column 10 arranged guide rail 34 on, at the several slidable along the column carriage 36 are attached, each one a receptacle 37 have, with the control section 25 every second ratchet lever 20 can interact. Depending on the displacement position of the respective carrier slide 36 Thus, the pivoting of a ratchet lever 20 with that of another ratchet lever 20 coupled or decoupled. About her guide rail 34 and the associated carrier carriage 36 can depending on the design of the latch lever 20 the desired division be switched on. Unnecessary ratchet levers remain fixed in each case under the used ratchet levers in their respective position. A special form of ratchet lever 20 This is an advantage, but not a condition.

The Lets can in principle from approximate Any material that has sufficient stability and stiffness even with larger loads features. As a material is, for example. Corrosion-resistant steel, in particular Stainless steel, which was either punched and then deburred or the was brought into the desired shape by means of laser cutting. Since the pallets with the stacking columns mounted on them often over a long time may be exposed to the weather, have to the moving parts and the goods in transit Contact standing pawls consist of weather-resistant material. For this Reason are preferably at least the pawls made of stainless steel.

The Lets can have different designs. The form in particular of The support range of the pawls depends on the desired Requirement, i. according to the contour of the transport or stored goods. Thus, the support area a straight, a curved or a cranked contour exhibit. Possibly. can additional stiffening ribs imprinted be.

The Number of superimposed or juxtaposed pawls per stacking column can vary within wide limits and depends primarily on the requirements. Also the distances the pawls of each other can be varied within wide limits, as well as the dimensions of the stacking column.

The Laser cutting process for the production of the pawls and the driver offers itself in particular due to the dimensional stability achievable with it and accuracy. In addition, this method is a burr formation largely avoided by which a sliding movements of the guide and / or the joints disturbed or could be hindered.

When Material for the stacking column is also suitable stainless steel or the like. For cost reasons will However, typically used galvanized sheet steel. Again, the necessary axle feedthroughs and recesses for the slide tours be introduced by laser cutting or by punching.
