Device for separating flat workpieces The invention relates to a device for separating flat,

Workpieces stacked in a magazine designed as a chute with a more precise and location-oriented separation taking place downwards from the device, especially for dynamo sheets with any external, identical shape to each other, for individual direct threading onto one Wave.

There are ready devices for separating flat, in one as Fall shaft trained magazine stacked workpieces known at those on two opposing Sohaohtseiten each a pair at a distance a workpiece thickness arranged one above the other, by a cam or Eccentric, jointly controlled slides are provided, the mutual movement coordination of the penultimate, i.e. the one above the lower one Move the work piece by applying pressure to the side, hold it at its height and while doing this move it under Release workpiece.

Other known devices for separating flat workpieces are designed in such a way that a safety device designed by means of a slider holds the workpiece above the lower workpiece in its height and the one below Werks tüok duroh «an exit opening on the side of the magazine, which can be moved downwards in the stacking direction.

is bordered by means of a movable in the direction of the outlet opening Eject slider separates.

In the known devices described first, ea often comes up suggest that workpieces that are slightly wavy or warped, as well as those whose surfaces have different degrees of quality or their thickness relatively high tolerances among each other, are not detected or stick to each other, whereby the working rhythm of the device is interrupted. In addition, the separation of the workpieces is relatively imprecise, which is why there is no direct threading of the with a hole provided workpieces on a shaft is possible. Furthermore, the separated sheet metal disks tend to one before leaving the device mutual jamming.

While the »broad type of known devices described are such Eliminate disadvantages resulting from the quality of the workpieces, are suitable see these gate poles only to one side and not downwards taking place position-oriented separation from the device.

Furthermore, in both known devices, the movement steps belonging to a work cycle are in some cases still relatively extensive and still take place in different directions.

The purpose of the invention is that of the known devices nooh as far as possible to eliminate inherent disadvantages and one such Device au create a single direct threading for workpieces equipped with a bore after leaving the device on a wave and so high with reliable operation

Working speeds achieved that lead to an automatic production process correspond to or are superior to the modern eating habits.

The invention is based on the object of a simply constructed device for separating flat workpieces stacked in a magazine designed as a chute, with any number of identical workpieces to create the outer shape, the small movement steps with a high working speed, which take place in just the same sighting Flat workpieces with a usable surface finish safely isolated and downwards in a constantly precise position-oriented direction weed out.

The object was achieved according to the invention in that below one Clamping jaw a fixed support and between this clamping jaw and the fixed support a transverse to the stacking direction to the lower one of the stacked workpieces movable separating slide as well as on the opposite side on the same level of the fixed support a support that can be moved transversely to the stacking direction and, at the same level as the separating slide, an equally movable holding slide of this type are arranged that in each case always in the same direction after the movement of the clamping jaw of the separating slide to a predetermined one Measure and shortly after the start of movement of the retaining slide and during its movement the movable support can be moved until the clear width between the supports and the slides is slightly larger than the width of the workpieces at this point and the return movement of the ^ lemmbackene only takes place after the movable support and the Sliders are moved back.

It is provided according to the invention, the holding slide means To press spring force to the starting position and to connect the movable support and the holding slide by means of a stop in such a way that the last movement step of the movable support can also be transferred to the holding slide. Furthermore, it is expedient that only the separating slide and the movable support for carrying out the movement steps and the clamping jaws, which press against the workpieces by means of spring force, are connected to the drive members for briefly releasing the workpieces.

These extremely small movement steps, all taking place in the same direction, still have the expected working speed of the door direction significantly exceeded.

This has become a device that operates safely at high speed created, which stores the downwardly separated workpieces so precisely and in a position-oriented manner that a single direct threading can be executed from dynamo sheets provided with a Hitten bore on a shaft. The application of this invention thus makes it possible to save a station, which was otherwise necessary in the automatic production process, where the workpiece is placed separately on a setting mandrel serving wells would have to be brought.

In the drawing, the invention is shown using an exemplary embodiment and explained in more detail below
