Device for embroidery machines

for the production of eyelet embroidery

The innovation relates to a device for automatic embroidery machines for the production of hole embroidery, with additional to the needle bars at least one drill rod is arranged on the embroidery head, which has a drive is reciprocable.

Drilling devices on multi-head embroidery machines for production of perforated embroidery are known in various designs. The devices of this type have the defect that the elaborate structure many. Components such as eccentrics, levers, cam pieces and springs requires and different components also work in the normal embroidery process if no drilling process is carried out. This causes unnecessary wear and tear on the components. Since the impulse is given to jacquard machine-controlled Automatic embroidery machines mostly via contact strips on the punch card

occurs, there is often incorrect switching due to wear and tear.

The task of the innovation is to create a simple drilling device of the generic type that can only be used when drilling can be switched on and when changing the type of processing, such as from embroidering to drilling, no reduction the speed or a standstill of the embroidery machine requires.

The object is achieved according to the invention in that the needle bar and drill bar each have an upper coupling part and one via associated lifting magnets Rotation of the needle bar and the drill bar for connection or decoupling with a coupling lower part is to be brought into puncture as a reciprocating cock of the drive. This has the advantage that with a small number of components, the drilling device can only be switched on in the event of drilling effects and thus no additional wear occurs during the embroidery process. The change of the processing type is also without standstill of the automatic embroidery machine.

It is also proposed that the needle bar and the drill rod with its coupling upper part in the raised position are held as a rest position via a shelf or lock.

A simple design is created in that the needle bar and the drill bar rotate in one Are guided displaceably via lifting magnets causing adjusting ring.

In the drawing, an embodiment of the innovation is shown schematically. Show it:

Fig. 1 is a view of a device in the embroidery position,

FIG. 2 shows a view according to FIG. 1 in the drilling position.

In the arrangement shown, a needle bar 1 is moved via a drive element not shown in detail. and moved here, a coupling lower part 8 being driven as a block. To do this, the needle bar engages 1 arranged coupling upper part 7 into the coupling lower part 8 a. The needle bar 1 is at 70 ° arranged rotatably and actuated with an associated lifting magnet 5 via an adjusting ring. Through this Rotation, the upper coupling part 7 can be separated or coupled from the lower coupling part 8. In the separate In the raised position, the needle bar 1 is held in the position of rest by means of a lock 9.

To actuate a drill rod 2 parallel to the needle bar 1, an associated upper coupling part 3 is shown in FIG the lower coupling part 8 can be latched accordingly by the drill rod 2 also having a lifting magnet 6 can be rotated by 70 ° via an adjusting ring. In the rest position, the upper coupling part is supported on a shelf 4.

As a result, the drilling device can only be switched on when drilling work is actually to be carried out; self when sewing normally for a long period of time. The drilling information is provided via a combination of stop and jump stitch signals queried. This handling means that there are no false impulses, as with Wear, dirt or the like from the contact strip.
