Description

Automatic wire cutting and laying device for the manufacture of brushes

The innovation relates to a device for automatic Cutting off and evenly laying on of corrugated wire for the production of brushes,

From DE-OS 2552213 a device for making brushes is known in which the bristle material is first drawn off the supply roll via feed wheels and then fed to a cutting device This feed device is very complicated in its construction due to its ilebel mechanism and therefore very susceptible to signs of wear of plastic bristles on tamping machines for brush production suitable DE-OS 1632375 contains a device for dividing bundles of bristles of a predetermined size for brush production, the bundles of bristles evenly distributed on a conveyor belt by rotatable drums earth _o According to this innovation, the bristles are already "stacked" in cut lengths in a magazine. This device is therefore not suitable for processing corrugated wire, since the individual corrugated wires would get caught in one another in such a way that separation would be extremely time-consuming <>

The aim of the innovation is to avoid the problems described in the prior art and to create a device which makes it possible to process corrugated wire for the manufacture of brushes to remove the raonotonous, unhealthy Operations that were previously carried out manually automate",

The object of the innovation is to propose a device for automatically cutting and placing corrugated wire, whereby the wire hooking into one another is reduced to a minimum. According to the innovation, the problem is solved in that there is a wire strand with a thin diameter on the supply roll, which from the outset reduces the entanglement of the wire. This wire strand is drawn by a pressure roller and a feed roller from the supply roll and pushed into a with the rotatable Tronmelmagazins "After completion of the feed movement of the cutting is performed upon the wire strand ₀ The cut wire strand is gradually then by the rotating drum magazine according transported below, wherein it falls on the brush manufacturing machine when the corresponding groove of the drum magazine is perpendicular downwards in relation to the brush manufacturing machine «,

The hiring is explained in more detail with reference to the embodiment shown in the drawing

Summary

Automatic wire cutting and placement lengthways for brush production

The innovation relates to an apparatus for automatically cutting and placing of crimped wire for manufacturing brushes, wherein a good Abteilbarkeit of the corrugated wire and a uniform distribution of the wire billion achieved leg laying on the brush manufacturing machine ₀ In the apparatus are a feed roller, a pressure roller, a Wire guide, a knife and a rotatable drum magazine are available, which are jointly connected by gear wheels, chains and other machine elements o The cutting length of the wire strand is determined by adjusting the connecting rod, which is attached to the feed roller _o The feed roller and the pressure roller push the wire in the grooves of the drum magazine ο After the end of the feed movement of the feed roller, the cable strand is cut and then the drum magazine rotates and places the cut wire strand on the brush manufacturing machine ο
