DE2840626C2 - Device for flush-edged stacking of rectangular workpiece plates of the same dimensions - Google Patents

Description

The invention relates to a device for stacking right-hand workpiece plates flush with the edges same dimensions, with d *; n features of the generic term of the claim.

Facilities of this type are already known here, although this cannot be documented in print are the aligning members arranged above the support table so that they can be adjusted parallel to its support surface for the flush stacking of workpiece plates each adjustable by such a distance that each Work cycle the length and width dimensions from the largest to the smallest stackable on the device Workpiece plate to be bridged.

Since the formats of stackable workpiece plates can differ considerably from one another - the largest format usually has the dimensions of 2000 mm x 6500 mm, while the smallest format with 1200 mm-600 mm - this inevitably results in smaller ones when stacking workpiece plates Format or with the smallest dimensions for the adjustable alignment members correspondingly large Bridging paths, making the stacking performance of such Facilities is affected accordingly.

The invention is therefore based on the object of providing a device with the generic features of the claim to improve so that the adjustable aligning members when they are brought into abutment the first workpiece plate of a certain plate format automatically set so that then For stacking other workpieces of the same format, only a short infeed path has to be carried out This means that high-speed stacking is possible with any panel format.

This object is achieved by the characterizing features of the patent claim.

In the device according to the invention, the adjustable aligning members take place before they are brought into abutment the first workpiece plate of a series of workpiece plates of the same format an initial position one, in which workpiece plates with the largest stackable format between the movable and stationary Alignment members can be placed on the support table.

If the device then comes into operation, the adjustable aligning elements are directed towards the workpiece plate controlled with their aligners after approaching one workpiece edge the workpiece of the alignment member assigned to the movable alignment members and serving as a stop and align with this. As soon as the workpiece plate through the more firmly established alignment elements on the Auflsgetisch set in a predetermined stack position is, lead the alignment members, due to the then exerted by the workpiece plate on the alignment plate Reaction force a relative movement to the latter, whereby it is a predetermined, by the Cover the feed path measured by the switching device in the direction of the workpiece plate. Have the alignment organs Returned this feed path, they are locked in the end position reached, after which the alignment plate be withdrawn relative to the alignment members carrying them into an initial position, wherein they are out of contact with the relevant plate edge. The next workpiece plate can now open be placed on the support table, then for aligning and stacking them flush with the edges only to control the alignment plate of the movable alignment members in the direction of this workpiece plate are.

The alignment plates thus have to align the items that are subsequently to be deposited with flush edges Workpiece plates only have to have a short, quickly covered work path for alignment, being used to align the first Workpiece plate required pre-setting of the movable alignment elements automatically or without involvement an operator.

In the drawing is a schematic representation Embodiment of the device according to the invention shown in plan view

The support table 1 is divided in its longitudinal direction. In the slot-shaped space formed thereby drives, motor-driven, an alignment member 6 forming a carriage for the longitudinal alignment of a Workpiece plate 2. This alignment element b carries alignment plate 9. Dt? Guide of the trolley is located below the table level.

After the workpiece plate 2 has been placed on the table, a switch 8 located in the table is actuated and starts aen the longitudinal alignment member 6 forming carriage.

This moves alignment plates 9 arranged on this and extended at reduced pressure Direction of an aligning member 3 forming a fixed stop, the workpiece plate 2 against this is pressed. As soon as the alignment plates 9 are pushed back by the counter pressure, the carriage stops or the alignment member 6. This is then locked and the alignment plate 9 are again retracted.

At the same moment, the alignment members 7 are pivoted up for the transverse alignment of the workpiece plate and their alignment plate 9 extended under reduced pressure. Then that starts a drivable one Alignment member 4 which forms a stop and which forms a stop traverse equipped with a stop pin 5. It is in the two guides 10 above the load

table 1 out and moves against the alignment members 7 until their alignment plate 9 through the resistance the workpiece plate are pushed back. The stop traverse or the alignment member 4 is thereby stopped and locked, and its alignment plate 5 are withdrawn. The device is now set to the plate format

After the placement of each new workpiece plate, the alignment plates 9 of the alignment members move alternately 6 and 7 in the direction of workpiece plate 2 and push them against one of the fixed stops forming alignment member 2 and a stop traverse forming alignment member 4 formed right stop bracket.

Claims (1)

Claim: Device for flush-edged stacking of rectangular Workpiece plates of the same dimensions, with a support table for picking up stacks and with an alignment device, the two pairs of opposite one another above the support table Has alignment members, one of which is parallel to one edge each forms on the support table deposited workpiece plate extending stop and the other parallel arranged to be adjustable to the support plane of the workpiece plate and to the edge adjacent to it the workpiece plate can be placed, characterized in that each one of each other Allocated alignment elements (3, 6 or 4, 7), aligning plates (9) that can be extended in the stop direction carries the from its extended position after the alignment of the first workpiece plate (2) withdraw through the counter pressure and thereby after a predetermined path over a switching device first of all a shutdown and locking of the respective alignment element (3 or 6 and 4 or 7) and then backstcuerbac to an initial position.
