Abstract

The invention relates to a transferring device (10) for plates for accumulators, said plates being combined into pairs, wherein each pair comprises a pocketed and a non-pocketed plate. The transferring device has two continuously rotating supports (11), in which claw plates (13) with claws (16) are mounted. The claws (16) of the claw plates (13) grip a plate pair and move same to a table (3) on which a stack of pocketed and non-pocketed plates for accumulators is formed. When a stack is formed which should contain an additional non-pocketed plate (23) for accumulators, the additional plate (23) for accumulators is aligned while being moved towards the table (3) in that the claw plates (13), on the claws (16) of which the plate (23) lies, is moved out of the supports (11) until the claw plates rest against the lateral edges (22) of the plate (23). The plate (23) for accumulators aligned in this manner is then deposited on the table (3) or on a stack located there in an aligned manner.

Description

METHOD AND DEVICE FOR STACKING

PLATE-SHAPED OBJECTS

The invention relates to a method having the features of the introductory part of claim 1.

The invention also relates to a conversion device with the

Features of the introductory part of the claim directed to the converting device.

In manufacturing processes, the task often arises of producing plate-shaped objects, in particular plate-shaped

Objects with a substantially rectangular shape to be stacked on top of one another.

An example of this is the manufacture of accumulators, in which positive and negative plates for accumulators

stacked on top of each other to form stacks.

A converter with which stacks of positives and

negative plates can be formed by accumulators, AT 355 500 B is known.

With the transfer device known from AT 355 500 B (also called "disk wheel"), which is assigned to the end of a conveyor device and which has two continuously rotating carriers opposite one another and several rotatably mounted on them

Claw plates on which pivotable claws projecting into the space between the carriers are provided

Plate-shaped objects that are conveyed by the conveyor at constant intervals are implemented. The claws grip the plate-shaped objects conveyed by the conveyor device and lift them to a table on which the plate-shaped objects are placed

be stacked on top of each other. The claw plates are opposite driven by the carrier in such a way that the plane defined by the upper edges of a pair of opposing claws always runs parallel to the table and the conveyor device and remains essentially horizontal. In the device known from AT 355 500 B, the supports of the relocating device are circular disks and the claw-bearing claw plates are flush with the disks. The distance between the panes corresponds essentially to that across the

Direction of conveyance measured extent (= width) of the

plate-shaped objects.

The device known from AT 355 500 B is in particular for the production of packages (stacks) from plates for

Suitable for accumulators. Such packages comprise positive and negative plates, which are arranged alternately, with either the positive or the negative plates being received, ie "pocketed", in so-called pockets (made of non-woven material).

Examples of the use of the device known from AT 355 500 B can be found in AT 392 371 B and AT 387 870 B.

If with the known converting device like this

For example, in AT 392 371 B and AT 387 870 B, if plates are implemented that are held in pockets, the distance between the carriers corresponds to the dimensions of the pockets, that is to say the width of the pockets.

There are cases where at one end, especially the lower end, the stack of positive and negative plates for

Accumulators one unpocketed plate for one

Accumulator (positive or negative plate), which is also referred to as "skip plate", is to be arranged. The problem with the use of the device known from AT 355 500 B is that the distance between the carriers, between which the Plates are transported that corresponds to the width of the pockets, so that not pocketed, i.e. narrower, plates under

Under certain circumstances, they cannot be placed properly, for example at an angle, aligned on the table.

In the elevator known from DE 1 031 214 B, swivel arms, which are loaded into their operative position by springs, are attached to chains via carriers. The distance between the swivel arms

each other can be changed and is locked in the desired position with the help of socket pins or with the help of eccentrics. Conveyor pieces (boxes, etc.) are from the

Swivel arms centered towards the middle. DE 1 031 214 B only discloses an adjustment and locking of the swivel arms, but not that the distance between the swivel arms is changed while a conveyed piece is being moved.

The invention is based on the object of developing the method known from AT 355 500 B and the device known from AT 355 500 B in such a way that, in particular, plates for accumulators, but also any plates with a substantially rectangular outline, are placed on the table in the correct orientation will .

This object is achieved according to the invention with a method which has the features of claim 1.

A transfer device which is particularly suitable for performing the method according to the invention is the subject of the claim directed to the transfer device.

Preferred and advantageous embodiments of the

inventive method and the inventive

Devices are the subject of the dependent claims.

Since in the procedure (method) according to the invention the of the transfer device from the end of the conveyor

The plate to be picked up and placed on the table is aligned during the transfer, the plate is placed on the table in the correct and desired orientation. This applies to any plates and in particular to non-pocketed plates for accumulators, which are to be arranged at one end of a stack of positive and negative plates for accumulators, with the positive and / or negative plates being pocketed.

Further features and details of the invention

Device emerges from the following description of an exemplary embodiment of the invention with reference to the drawings. It shows:

FIG. 2 shows another view of the transfer device from FIG. 1, FIG. 3 another view of the transfer device from FIG. 1,

In the area of the delivery end 2 of a conveyor device 1, which are preferably at regular intervals from one another

has arranged driving claws, a transfer device 10 ("disk wheel") is provided, the plate pairs, comprising a positive and a negative plate for

Accumulators, with one of the plates in a pocket Nonwoven material is added, lifts to a table 3 (transfers) and there stacked on top of one another to form a stack of panels. The

Transfer device 10 has two circular carriers 11 which

are attached to a shaft 12 so as to be adjustable in the axial direction. The adjustability of the supports 11 allows their spacing from one another to be adapted to the width, measured transversely to the plane of the supports 11, of pockets in which plates for accumulators are accommodated. Circular claw plates 13 are embedded in the carriers 11, the arrangement being such that the inner surfaces 14 of the claw plates 13 with the

Inner surfaces 15 of the carrier 11 are aligned when the claw plates 13 are in their ready position (cf. FIG. 7). The

Claw plates 13 carry pivotably mounted claws 16, whereby a mechanical control 17 with the aid of an endless belt 18 ensures that the upper edges of the claws 16 are always parallel to the transfer device 10 when the transfer device 10 is rotated

The conveying direction of the conveyor 1 and to the level of the table 3 run. The claws 16 are of leaf springs 19 so

loaded that they assume a position protruding into the space 20 between the carriers 11. The speed of movement of the

Conveyor device 1 and the transfer device 10 (des

Disc wheel) are coordinated so that then a pair of claws 16 the plane of movement of the upper run of the

Conveyor device 1 cuts when a pair of plates (positive and negative plate) is in the area of the claws 16

is located. The pair of plates is then lifted by the claws 16 and moved towards the table 3. There the pairs of plates are deposited on the table 3 itself or on a stack of pairs of plates that is already located there by pivoting the claws 16 back. If a sufficiently high stack has formed on the table 3, then a pull-out device is actuated and pushes the stack out of the area of the transfer device 1, for example to a conveyor belt, not shown.

The carriers 11 are preferably circular disks. As part of the However, the invention is also an embodiment

drawn, in which the carrier 11 is star-shaped, the claw plates 13 being provided in the arms of the star.

Both when the plates for accumulators are stacked to form a stack and when the stack is pushed out of the area of the supports 11, the smooth inner surfaces 15 of the supports 11 serve as guides, so that clean stacks are formed and the objects stacked on top of one another do not fall off the table 3

be thrown down.

In the conversion device 10 according to the invention are

Claw plates 13, on which the claws 16 are arranged, transverse to the plane of the carrier 11, which as circular disks

are formed, arranged adjustable. So they can

Claw plates 13 with claws 16 from a standby position in which their inner surfaces 14 facing the space 20 between the carriers 11 are aligned with the inner surfaces 15 of the carriers 11 facing the space 20 between the carriers 11 (FIG. 7), into one opposite these surfaces projecting position (effective position) are moved (Fig. 8). In the invention, opposing claw plates 13 are adjusted between the standby position and the effective position. It is preferred that the

Claw plates to the center plane between the beams 11

can be adjusted symmetrically so that panels not only

aligned, but also centered.

In the invention, as shown in Fig. 8, both

Claw plates 13 adjustable with respect to the carriers 11, the adjustment being carried out in such a way that mutually opposite

Claw plates 13 are simultaneously advanced into the space 2 between the carriers 11 and the movement of the claw plates 13 and the end position of the claw plates 13 (effective position) is symmetrical to a plane lying in the middle between the carriers 11.

To adjust the claw plates 13 relative to the carriers 11, are assigned to these linear drives 21, the

Linear drives 21 are preferably hydraulic cylinders,

especially pneumatic cylinders. But there are others too

Drives, such as electric servomotors, are conceivable to the

To adjust claw plates 13 from their ready position (in alignment with the carriers 11) into their operative position (above the carrier 11 above).

The claws 16 provided on the claw plates 13 (each

Claw plate 13 contains in particular two claws 16) are pivotably mounted in the claw plates 13 (see FIG. 5), the claws 16 being loaded into their projecting effective position by leaf springs 19, which are provided on the outside of the claw plates 13. Thus, the claws 16, in particular when pairs of plates move past the table 3 or stacked plates already lying on it, pivot and do not hinder the movement of the claw plates 13 relative to the table 3 or plates lying there.

If, with the described relocating device 10, pairs of a pocketed plate for accumulators and a non-pocketed ("bare") plate for accumulators are conveyed from the conveyor 1 and moved from the relocating device 10 to the table 3, the described device works basically similarly like the one from AT 355 500

known device.

If an unpocketed ("bare") plate is removed from the

Conveyor 1 is to be implemented on the table 3, opposing claw plates 13 from their

Ready position is moved into its effective position until its inner surfaces 14 on the side edges 22 of the plate-shaped object, in particular the bare plate 23 for

Accumulators, and align them. This is shown in FIGS. 7 and 8. It is provided, for example, that the claw plates 13 do not clamp the plate 23, since this would hinder the placing of the plate 23 on the table 3, for example.

The object aligned in this way - the bare plate 23 - is then in this position, namely the desired position and

Alignment on the table 3, filed.

When pairs of plates, one of which is pocketed, are to be moved again with the moving device 10, the claw plates 13, which have moved a non-pocketed plate 23 for accumulators, are moved back into their ready position and the moving device 10 continues to work as described above, to form stacks of plates.

It should be noted that the relocating device 10,

in particular the carrier 11, is / are continuously moved and that in each case two opposing claw plates 13 or only one of them are / is moved from their standby position into their operative position when a smaller (narrower) object, such as a plate 23 that is not pocketed for

Accumulators, is to be implemented. The remaining claw plates 13 can remain in their ready position, as they are a for the transfer of wider plate-shaped objects, such as

Pairs of plates consisting of one pocketed and one not

Pocketed plate for accumulators, have appropriate distance from each other.

The method according to the invention and the device according to the invention (transfer device 10) can be used in different ways.

In one embodiment of the invention, pairs, comprising a non-pocketed (naked) and a pocketed plate for accumulators (a positive and a negative Plate), removed from the delivery end 2 of the conveyor 1 for feeding in pairs of plates, moved by the transfer device 10 to the table 3 and deposited on the table 3. During this conversion, the facing inner surfaces 15 of the carrier 11, that is to say inwardly pointing, and the inwardly pointing inner surfaces 14 of the supports which are rotatably mounted therein

Claw plates 13 with claws 16 spaced apart from one another, which is the width of the pockets (the pocketed plates for accumulators) measured transversely to the plane of the carrier 11

corresponds.

If the stack of positive and negative plates for accumulators formed on the table 3 is to contain a "naked" positive or negative plate 23 ("skip plate") at one of its ends, a naked plate 23 is conveyed to and from the conveyor device 1 the converting device 10 detected. While moving the bare plate 23,

especially towards the end of the transfer movement, the

Inner plates 13, which hold the bare plate 23, moved from their ready position (Fig. 7) to their operative position (Fig. 8) in the space 20 between the carriers 11 until they are on the lateral edges 22 of the bare, adjacent to the claw plates 13 Place plate 23 for accumulators and have aligned the bare plate. Thus, the bare plate 23 for accumulators is placed correctly aligned on the table 3 or on a stack of pairs of plates for accumulators located there.

In another embodiment of the invention, pocketed plates for accumulators can also be aligned while they are with the relocating device 10 of the

Conveyor device 1 can be implemented on table 3. This embodiment of the invention is advantageous when pairs of plates for accumulators, comprising pocketed and bare plates, are to be implemented, and the width of the pockets is smaller than the distance between the inwardly facing surfaces 15 the carrier 11. By moving claw plates 13 from their ready position in their effective position are in this

Embodiment also aligned pocketed plates and placed in the correct position on the table 3. This embodiment has the advantage that the relocating device 10 can also be used for plates for accumulators, the pockets of which have a width that is smaller than the distance between the carriers 11, without having to change the distance between the carriers 11 to the Adjust the width of the pockets with plates for accumulators.

In summary, an embodiment can be as follows

to be discribed:

A transfer device 10 for plates for accumulators, which are combined in pairs, each pair comprising a pocketed and a non-pocketed disk, has two continuously rotating supports 11 in which claw plates 13 with claws 16 are mounted. The claws 16 of the claw plates 13 grip a pair of plates and move them to a table 3, on which a stack of pocketed and non-pocketed plates for accumulators is formed. If a stack is formed that has an additional, unpocketed plate 23 for

To contain accumulators, the additional plate 23 for accumulators becomes during its movement towards the table 3

aligned in that the claw plates 13, on the claws 16 of which the plate 23 rests, are moved out of the supports 11 until they rest against the lateral edges 22 of the plate 23. The thus aligned plate 23 for accumulators is then placed in alignment on the table 3 or a stack located there.
