Abstract

The invention finds application in the packaging of individual sheets for stators or Laeufer of electric motors. The aim of the invention is to tap individual sheets in a single pass under pressure of predetermined package height with great accuracy. This object is achieved by the invention that a quasi-infinite stack Bleeche from the magazine is introduced through a collet into the receiving opening of a circular work table and further divided and raised by narrowing the wedge-shaped claws of the collet in the desired separation plane and raised, with loosely adhering plates be restrained by the starting from below, also claw-like scrapers on the left in the rotary table package. According to the invention, the separation takes place upon compression of the sheet stock, wherein the required pressure is exercised by means of bumpers over the uppermost sheet of the entire stack. Furthermore, the device is characterized in that the collet is both on the one hand in its engagement height or position of the parting plane and on the other hand in their penetration depth of the claws in the sheet stack adjustable.

Description

Field of application of the invention

The invention relates to a device for automatically packaging a plurality of stamped sheets for electric motors, which taps off the laminated core by means of a collet with high accuracy under pressure.

Characteristic of the known technical solutions

In the case of such devices, it is customary to determine the number of sheets or the number of sheets by counting or weighing

Likewise, it is also known that the individual sheets are tapped from a stack of sheets by means of separating wedge or claws and conveyed via a runway for packaging in a pressure-exerting device «

It is also known that a set-actual comparison is carried out for the insertion of sheets into the packaging device before the mechanical consolidation of the package

ψ *

and then the number of sheets is corrected.

In the known methods, however, the Auffedern of the sheets after tapping and the exact separation in the parting plane remains problematic «, In general, the known methods and devices by defect, such as low Paketiergenauigkeit or additional Correction and on the other hand, unreliable function or additional steps marked.

Object of the invention

The object of the invention is to provide a method and apparatus for the efficient production of laminated cores of predetermined strength for electric motors, which is characterized in particular by a high Paketiergenauigkeit and exact separation of the sheet stack, the disadvantages of the known solutions should be avoided in terms of technological complexity <>

Explanation of the essence of the invention

This is essentially achieved according to the invention in that the located in a removable tubular magazine sheets are lowered with the magazine perpendicular to the receiving openings of the underlying rotary table · that is, in contrast to known solutions, the supply of sheet metal required for the sheets in one Hub, so that also time is savedo Furthermore, the pressure in the round table lowered sheets over the entire sheet supply pressure exerted compressed and taken in the area jier required parting plane radially by means of collet, separated and fixed. The chuck with its wedge-shaped claws can be adjusted with respect to their package height to be taken as well as the penetration depth into the sheet stack ©

206 54 7

In a further operation, the sheet stock is lifted together with the collet from the rotary table and the remaining round table in the laminated core is retained, including still loosely adhering plates arranged by the round table also claw-like scraper.

For further processing, in contrast to the known methods, both a rearrangement and a correction of the sheet stack located in the rotary table are no longer necessary.

In the next cycle of the rotary table can be supplied to the advanced laminated core, the shaft, at the same time in Voraustakt turn the process of Paketierens go go

embodiment

In drawing 1 an embodiment of the device for automatic packaging of a plurality of individual sheets is shown in section.

1 designates the sheet stack ready for packaging in the magazine. The sheets to be packaged are lowered through the open collet 2 down to the bottom of the receiving opening 3 of the rotary table 4, wherein a position determination of the individual sheets is carried out by two to the recessed in the rotary table «guide mandrels 6.

inserted in the rotary table scrapers 5 offset by 90 °

By acting on the top sheet of the magazine stock pressure ram 7, the sheets are compressed such that the bottom of the receiving opening 3 of the rotary table 4 serves as an abutment *

The collet at its lower edge inwards expiring in wedge-shaped claws 8, is reduced in their span and penetrates with the designated claws in the sheet metal

stack or detects the bottom plate of the magazine stock.

When lifting the collet with the held sheet stock only a few sheets on the parting plane 9 on the sheet stack under spring pressure also provided with wedge-shaped claws striker are engaged by the springs 10 in the parting plane and hold loosely adhering sheets of the finished laminated core 11 in the rotary table 4 back. For the rotor shaft to be introduced in the next cycle of the rotary table, the bottom 12 of the receiving opening of the rotary table is provided with an opening 13.

To adjust the device or to adjust the operating state, the collet chuck is held in the upper region in a collet neck 14 by means of groove nut 15 and lock nut 16 in the respective height of the required parting plane.

While the pin 17 when lifting and lowering the collet locked their position against rotation, the coupling ring 18 serves for storage and management of the nut 15. The regulation of the collet with respect to their depth of penetration in the parting plane is realized via the grooved nut 19 and lock nut 20, wherein by means of said nuts, the conical clamping sleeve relative to the collet displaced thereon and thus the desired state of stress is predetermined.

To limit the travel of the clamping sleeve on the collet while the formed on the claws support collar of the nut 19 serves as a stop ,,
