Abstract

The stacking column comprises a U-profile frame (2), in which swiveling plates (10, 11) are mounted on bolts (6) which fit through the walls (4) of the frame. These have springs (1) mounted on them which bias the plates to the upwards position.

Description

The present invention relates to a stacking column for storing flat warehouse goods nearly same shape and size in certain Distances above or side by side, with several stacking columns each in a frame form a transport unit. Such devices are used For example, for stacking molded sheet metal parts in the automotive industry. These are removed from the presses and before further processing by means of stacking columns horizontal, vertical or oblique stored.

Stacking columns are known in various forms and designs. A stacking column usually has a large number of ratchet levers, one above the other or one next to the other. When placing a product on a lower latch, it is pivoted from a ready position into a working position. It takes a subsequent pawl with it, which in this way moves from a rest position to the standby position. Such stacking columns are for example in DE 298 09 118 U1 . DE 298 03 921 U1 or DE 43 11 585 A1 described.

In the case of the mentioned stacking columns the individual pawls with one another by a lever mechanism connected, with the help of which the individual pawls rotate take each other around the axes of rotation.

The stacking column in DE 298 09 118 U1 has pawls rotatably mounted in a frame, with stops projecting from the frame against which the pawls strike in the working position. The pawls described here are made in two parts. The pawls are connected to one another by a lever mechanism (not described in more detail).

To set up a next jack Various lever mechanisms are in a standby position described.

In DE 298 03 921 U1 the stacking column has specially shaped erection means for the next jack.

In DE 297 04 692 U1 an elastic band is proposed, which should cause a pawl reset. Such solutions are complex and complicated to manufacture or they do not guarantee reliable operation over a longer period of time.

To bridge the distance between the individual pawls, these are in DE 43 11 585 A1 angled. The handles have bevelled sides so that they engage conically. This allows the distance between the individual pawls to be reduced. The end of the pawls is folded and thus forms molded drivers.

In the case of vertical storage of shaped sheet metal parts, the individual pawls of the stacking columns, such as in DE 3807663 A1 , either connected by means of linkage or the pawls are specially designed so that, for example, in DE 10053268 A1 , the center of gravity is shifted in such a way that the pawl levers still fall back into the rest position.

It is an object of the invention to further develop the generic stacking column that with a simple construction they also function reliably a horizontal or oblique Installation for holding components in a horizontal or inclined position guaranteed. On elaborate setback and Connection mechanisms should be dispensed with. In addition, should individual parts of the stacking column are universal be usable or reusable if, for example, others Sheet metal parts made a change of the distances between the jacks.

According to the invention, the object is achieved by Features of claim 1 solved. Design features are set out in subclaims 2 to 6.

The stacking column according to the invention consists of a U-shaped jacket for receiving a variety of side by side or one above the other arranged ratchet levers. The latch levers themselves are punched, straight through Sheet metal parts with a side edge and contained therein Bores for receiving bearing bolts. The ratchet levers are each in opposite The jacket cheeks are movably supported in pawl bearings. On the bearing pin a coil spring is applied in such a way that one of the two protruding free ends of the coil springs on the adjacent ratchet lever or strikes the adjacent bearing pin and the second protruding free end of the coil spring under tension so under the respective ratchet levers is that these are kept folded in the rest position.

On the frame side is on each latch lever a driving bracket attached. This is dimensioned so that when swiveling down, the next ratchet lever in the ready position brought. On the back of the coat there are stops for one Working position of the ratchet lever, which comes from the back of the jacket punched tongues and bent towards the latch lever can be.

In a preferred embodiment become the attacks by molded from the back of the jacket Recesses formed. The pawl levers are so far in the direction The back of the jacket is elongated, that they reach into the recess and in the working position of the upper recess edge.

The driving angle can be on the ratchet levers for example by spot welding or releasably attached. At a preferred embodiment the driving angles in oblong holes are rectangular Slidable to the bearing pin and by means of a screw connection attached.

The stacking column according to the invention is simple and inexpensive to manufacture. On elaborately shaped parts can be used by using mainly stamped and edged sheet metal parts to be waived. The stacking column also has few moving parts. In particular, complex and fault-prone connection mechanisms can be dispensed with. The stacking columns can be adapted to changing conditions due to easily changeable properties, such as the position of the swivel axis but also the weight, the type of fastening, the dimensioning or the shape of the driving angle. In particular, the ratchet levers can be manufactured more effectively in larger quantities by exchanging differently dimensioned driving angles.

The invention is as follows an embodiment described in more detail. Show it:

1 stacking column

2 ratchet lever

3 coat

In the 1 Stacking column shown consists of a U-shaped jacket 2 , in his coat cheeks 4 at the intended distance of the in 2 shown ratchet lever holes 14 are located, which act as a pawl bearing. The ratchet levers 3 themselves are straight punched sheets in T-shape, the lateral ends of which are folded up. In these side upstands 7 there are holes 5 with the holes 14 in the two cheeks 4 correspond. Through the holes 5 and 14 are bearing bolts 6 to hold the ratchet lever 3 plugged. So that not every bearing pin 6 must be screwed is over the height of the jacket cheek 4 a cover plate 15 provided, which is screwed 3 times on both sides in the present example.

On the bearing pin 6 is a spiral spring 1 applied. The two ends of the coil spring 1 are extended so that one of the two free ends on the adjacent ratchet lever 3 or its bearing pin 6 strikes and the second free end under tension so under the respective ratchet levers 3 that this is at rest 10 kept folded.

On each latch lever 3 is a driving angle 8th firmly attached, either by means of a weld spot or by means of a screw connection. The right upward in the direction of the next ratchet lever 3 protruding legs of the driving angle 8th is dimensioned in such a way that the next ratchet lever is applied when a molded sheet metal part is swung down 3 in standby 11 brought.

In 2 have the ratchet levers 3 two elongated holes each 13 transverse to the swivel axis. In these slots 13 can the driving angle 8th moved and fastened with a screw connection. This makes it possible that when the latch distances are changed deliberately, for example because other sheet metal parts are to be stacked, only the driving angles 8th with changed leg length must be replaced. The ratchet levers 3 themselves can be used again, making their production more effective with larger quantities.

By moving the driving angle 8th the focus can be varied at the same time. This fact can be particularly advantageous if universal latch levers or stacking columns are to be produced, which should also be usable for horizontal or oblique storage of shaped sheet metal parts.

Because the bottom latch lever 3 must already be in the working position or at least in the ready position before inserting the first sheet metal part, this can have a longer latch tongue on which the first sheet metal part strikes.

A shift in the center of gravity of the ratchet levers 3 is also the driving angle due to a changed material thickness or weight 8th reachable.

3 shows the jacket with stops located on the back of the jacket 9 , which locks the latch lever in the working position 12 guarantee. These attacks 9 are out of the coat 2 punched out and towards the ratchet lever 3 curved tabs.

In order to always keep the first latch lever in the ready position, there is a stop on the back of the jacket 16 intended. This is also a tab punched out of the jacket, only that it is bent in the opposite direction to the ratchet lever, like the other stops 9 ,
