Abstract

In a device for the production of Zopfbürsten two feeders (3, 4) for wire bundles, two transport and holding devices (11, 12) for carrier discs (9, 10) and two braid heads (13, 14) are provided on a common machine bed (2) arranged in each case in mirror image to a vertical, central plane of symmetry (15) between the feed directions (3, 4) of the wire bundles are formed.

Description

The invention relates to a device for the production of Zopfbürsten.

Braided brushes are known and proven in various embodiments. For example, there are small brush head brushes with 6 to 12 braids, medium round and cup brushes with 14 to 40 braids and large round brushes up to 80 braids.

Common to such brushes is a carrier disk, as for example from the DE 201 18 776 U1 is known. For the manufacture of a plait brush, metal wires, mostly steel wires, are introduced in bundles into apertures in the carrier disk by a feeder, which are gripped by a so-called plait head on either side of the carrier disk, cut to length and bent over by 180 °. By turning and pulling the wires are then twisted by the braid head against a carrier plate fixed web.

Known devices for the production of Zopfbürsten, fully automatic pigtails, have reached their performance limit.

Against this background, the object of the invention is to make available a device for the production of braided brushes in which the production speed of braided brushes is significantly increased while conserving resources.

This technical problem is solved by a device for the production of Zopfbürsten, is based in the claim 1 that two feeders for wire bundles, two transport and holding devices for carrier discs and two braid heads are provided, which are arranged on a common machine bed are each formed in mirror image to a vertical, central plane of symmetry between the feed directions of the wire bundles.

The device according to the invention has a number of advantages. In contrast to two single fully automatic pigtails, a large number of resources are shared. So it only requires a common machine bed. It also requires only a common housing to comply with the relevant safety regulations.

In addition, the device according to the invention is extremely compact, since the length of the device is determined essentially by the two opposite braid heads and the depth by the, as seen from a front, successively sequential arrangement of the feeder, the braid heads and lying behind the transport - And holding devices for the carrier discs.

The space required including the enclosure of such a device amounts to only about 3.5 m × 2 m.

According to the invention it is further provided that axes perpendicular to the plane of symmetry of the wire feed devices, the transport and holding devices and the plait heads are aligned.

This measure allows the common use of, for example, carriers for the braid heads, in particular also a common use of guides, expediently for the transport and holding devices, which are arranged to be movable on a common machine bed fixed linear guide perpendicular to the plane of symmetry. As a result, an adaptation to different diameters of the carrier disks is made possible in a simple manner.

However, it is preferably thought that the transport and -haltevorrichtungen are independently movable. It can be made with the device according to the invention at the same time Zopfbürsten with carrier disks of different diameters.

In a constructive embodiment is further provided that the unwound from rolls of wire bundles are brought to the underside of the feeders. As a result of this measure, the wire rollers are arranged on the back of the device and remains the front side, the operator side, free of moving parts. Introduced into or under the machine bed, the wire bundles are then bent by 180 ° supplied by the feeders the carrier discs.

It can further be provided that only electric servomotors are provided for placing machine parts.

This also applies in particular to the placement of the transport and holding devices in relation to the plait heads, in order to position diametrically different carrier disks exactly behind the plait heads or feed devices. Since the plait heads and the feeders have purely electric drives, the machine control is comparatively easy interpretable. Thus, only a control can be provided, which allows a synchronous production of Zopfbürsten on both production lines. Conveniently, however, each production line can be controlled separately, at the same time, for example, different braided brushes Carrier disk diameter or braid brushes of different types produce.

The device according to the invention will be explained in more detail with reference to the drawing, in which only one embodiment is shown schematically. In the drawing shows:

1 : A plan view of a device according to the invention and

2 : a section along the line II, II in 1 ,

The device 1 for the production of Zopfbürsten has a machine bed 2 on. On the common machine bed 2 are two feeders 3 . 4 arranged for wire bundles.

The feeding devices 3 . 4 each capture a wire bundle, which according to the arrows 5 . 6 below or through the machine bed 2 are unwound from the back of unillustrated roles, between two double link chains 7 . 8th and lead these wire bundles in openings of the carrier discs 9 . 10 one. The carrier discs 9 . 10 are from two transport and holding devices 11 . 12 positioned and changed. The in the carrier discs 9 . 10 introduced wire bundles are then from two braid heads 13 . fourteen cut to length and bent around a support plate fixed ridge by 180 ° and twisted into pigtails.

The arrangement of the two feeders 3 . 4 for wire bundles, those of the two transport and holding devices 11 . 12 for carrier discs 9 . 10 as well as the two braid heads 13 . fourteen on the common machine bed 2 is a mirror image of a central plane of symmetry 15 which rises vertically between the feeding directions of the wire bundles.

In addition, are perpendicular to the plane of symmetry 15 aligned axes, here, for example, the axes 16 . 17 the feeding devices 3 . 4 , the axes 18 . 19 the transport and holding devices 11 . 12 for carrier discs 9 . 10 as well as the axes 20 . 21 the braid heads 13 . fourteen ,

In particular, the transport and holding devices 11 . 12 on a common machine bed fixed linear guide 22 by means of two electric servomotors 23 . 24 , independently of each other, relative to the plait heads 13 . fourteen or the feeding devices 3 . 4 for adaptation to different diameters of the carrier discs 9 . 10 be put.

Also for the placement of all other machine parts electric drives are further provided.

2 further shows that as a linear guide 22 two guide tubes arranged one above the other 25 . 26 are provided. On these guide tubes 25 . 26 are also the braid heads 13 . fourteen established.

Not shown in the drawing is a housing of the device 1 which complies with the relevant safety regulations.
