DD273045A1 - DEVICE FOR PERFORATED STACKING OF TRANSFORMED SHEETS - Google Patents

Abstract

The invention relates to a device for distanced stacking of formed sheet metal parts, which is mounted on a Verfahrwagen and actuated by means of an existing lifting device. In this case, the part spacing of the attached to over pulleys running flexible steel bands fastened workpiece supports can be variably adjusted, with a spring element pivots the workpiece supports in the appropriate position. The advantage of this device lies in the reduction of the number of stacking device and thus in the reduction of the material usage and the manufacturing cost. Fig. 1

Field of application of the invention

The invention relates to a device for distanced stacking of formed sheet metal parts with a frame, which is provided with facing the interior of the frame rows of workpiece supports on deflected support beams, wherein the workpiece supports are angordnet distributed on at least two opposite sides of the frame over the entire Stapolhöhe ,

Characteristic of the known state of the art

From DE-PS 3231964 a portable stacking container for stacked sheet metal parts is known, the best bus a frame frame, at both ends rotate about rotatable Kottenräder deflected conveyor chains attached thereto trunnion. The disadvantage of this device is that by the fixed chain pitch a νε-iable filing distance is not possible. Furthermore, a continuous shaft and an on and uncoupled rotary drive is necessary for synchronization of the conveyor pin located on the conveyor chains. This requires a lockable in and out of engagement with the conveyor chain chain locking, so that unintentional movement of the conveyor chains is prevented in uncoupled rotary drive. Due to the fully circulating conveyor chains, it is necessary to also attach the trunnions necessary for the partial support on the entire chain circumference.

Object of the invention

The object of the invention is to reduce the number of stacking devices and thus to reduce the cost of materials and Minimieruiig the manufacturing cost.

Explanation of the essence of the invention

The invention is based on the object, on a device of the type mentioned a variable distance with respect to the arrangement of the workpiece supports with e '.em linear drive system xu create.

According to the invention, this object is achieved in that the workpiece supports are arranged on flexible steel belts via a hole image according to the predetermined part distance, and an operating link between the work supports is provided within the clearance of the steel belts.

Ei'mo embodiment of the invention is that the hole pattern consists of slots in which the workpiece supports are slidably mounted.

A further embodiment is that the workpiece supports are designed to be pivotable and opposite to the support surface with a lever extension, in the effective region and at a bearing point of the upper deflection roller, a spring element is arranged.

Auiführungibeleplel The invention will be explained in more detail using an exemplary embodiment. Show

Fig. 1: Prinzipdarstellur.g the stacking device with lifting device (front view) Fig. 2; Illustration of the left roller holder in the area of the upper deflection roller FIG. 3: View according to FIG. 1 in the direction of the arrow

The apparatus shown in FIG. 1 for the distanced stacking of bleaching parts, referred to below as stacking magazine, consists

from a frame 1 with pairwise mounted on it roll holders 2 for receiving the guide rollers 3 and the steel strip 4mit the workpiece supports 5 and 6. A lifting device 10 is mounted below a mounted on the carriage 11

Stacking magazine arranged and connected via permanent magnets 8 with the lifting plate 7. The lowest workpiece support 5 is rigid

formed and connected to the lifting plate 7 and the steel strip 4. The adjoining upwards

Workpiece supports 6 can be pivoted away. Fig. 2 shows the penultimate loading position without bleaching parts 16. In the region of the bearing block 14 of the upper guide roller 15 is an am Roller holder 2 fixed spring element 9 is arranged, soft opposite to the support surface 13 with lever extension

12 provided workpiece supports 6 pivots in the corresponding position for sheet metal part holder.

In Fig. 3 is a partial view of the steel strip 4 is shown, which optionally provided with hole pattern b or L'angloch I.

can be to produce the corresponding part distance a between the workpiece supports 5.6.

The sheet metal tray in the stacking magazine always takes place in the same position. For this purpose, the lifting device 10 moves in the upper Position and moves there ^ ei the lifting plate 7, the bottom workpiece support 5 in the Beladestellunp. After the Blechteilnblage the lifting device 10 moves according to the Teiledistanz a down to the next Workpiece support 6 is in the loading position. It is on the lever extension 12 by the spring element 9 the Support surface 13 of the workpiece support 6 forcibly pivoted into the horizontal position. In addition to Gravitational effect, the lowering movement of the lifting device 10 is supported by permanent magnets 8 to at high Teefrequency to ensure safe lowering. When gpfüllem stacking magazine, the lifting device 10 moves to its lowest position and the carriage 11 with the on it

attached stacking magazine takes the required new position. The movable workpiece supports β are designed like a hinge and thus can be pivoted away when the entire sheet metal part stack 1 β is removed upwards.

Due to the design of the steel strip 4 with hole pattern b or slot I a variable part distance a can be achieved. That leads to

a more universal use of Stapelmoganzine, to reduce the number of magazines and thus to reduce the

Production costs and Materialein'jatzes. ·
