Description

Device for automatic removal and stacking of workpieces, in particular sewn workpieces

The invention relates to a device for automatic Removing and stacking the machine from an upstream machine, in particular from a sewing machine or sewing device coming workpieces in a magazine.

Devices are known in which the coming from an upstream work machine Workpieces by means of a rod-shaped support element, that of a receiving position in which the workpieces slide over the support element depending on the work of the upstream machine, by means of a drive - z. B. be moved away an endless chain, with the recorded workpiece on hanging down on both sides of the support element.

A device is also known in which the support element of the workpieces sewn for removal behind a sewing machine certain stacking device from a lower position in which it is of the sewn workpieces is slipped over, into an upper end position and then back again can be moved into the lower position.

With these known devices can only be relatively long and soft Stack workpieces on top of one another with sufficient security and in large numbers. trouble arise when short and / or stiff, sewn workpieces, for example collars or pocket flaps are to be stacked on top of one another by means of these devices. These difficulties are due to the support rod used, on which the recorded workpieces are placed must hang down on both sides of the support element in order to be able to withstand a plurality of stacked Workpieces to achieve sufficient stability of the stack. However, this is not the case if Even the first layer of workpieces to be stacked is not around the support rod due to its rigidity can put, but rests on this in the unstable state and already through the operation of the device occurring vibrations from the support rod falls to the floor.

These known devices are therefore used for a large number of the work that occurs in sewing companies sewing and automatic stacking of workpieces is not suitable.

The purpose of the invention is to eliminate these shortcomings, those when stacking workpieces, especially small, sewn and proportionate rigid fabric parts such as pocket flaps, collars and the like when using the known devices appear.

The invention is based on the object of a device for automatic removal and stacking that of an upstream machine, in particular a sewing machine or an automatic sewing device To create upcoming workpieces that make it possible to sew both small and large ones and unsewn workpieces, which can be rigid or flexible, from a sewing machine can be removed and stacked in a large number in an orderly manner on top of each other.

According to the invention, this object is essentially accomplished both vertically and horizontally controlled, a square movement executing, rust-like designed transducers for the. Work pieces and a fixed and vertically arranged, rust-like system part in the magazine solved for the lateral contact of the workpieces, with the bars of the transducer forming the grids in which the plant part are controlled displaceably in such a way that by means of a workpiece holder Workpiece conveyed on the pick-up is lowered in the magazine and after the vertical extension of the Magazine is raised to the level of the workpiece support and attached to it for the purpose of receiving the next one Workpiece is brought up.

One vertically and one horizontally acting are used to generate the square movement of the transducer Air cylinder provided. The drive of the workpiece holder takes place through two compressed air cylinders,

where the cylinder connected to the workpiece holder is horizontally pivotable and can be lifted by means of the other cylinder to the piece holder in a raised position over the workpiece to be removed and after lowering the workpiece hol ers to promote the transducer.

The cylinder causing the lifting and lowering movements of the pick-up is with a driver connected to the transducer. This is made of bars and a beam and has a vertical bar on, which is straight in a bracket between pairs of rollers and whose axis is parallel to that of the Air cylinder runs. The driver attached to the piston rod of the cylinder has a die Rod of the transducer with an opening enclosing play and is with adjusting screws for two of the compressed air cylinders controlling air valves.

In the bracket is a valve controlled by a compressed air valve Arranged brake cylinder for the pick-up rod, after lowering the pick-up onto the workpiece stack and uncoupling the carrier from the pick-up in the lower position of the cylinder activated by the driver via an air valve so that the sensor stored under its own weight on the stack of workpieces even after removal the rods from the magazine remain at this altitude.
