CONSTITUTION: Both sidewalls 20 of a top roller holder 10 are provided with a plurality of engaging parts each having at least one kind of recess, protrusion or hole 19 to enable the attachment of an adapter element 21 for accessories including a clearer roller, a suction device, a condenser, a cover or a yarn feeder guide.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a top roller holder in which a draft device in a spinning machine has an inverted U-shaped cross section.

[0002]

2. Description of the Related Art In addition to mounting a top roller on a top roller holder (load arm), various other accessories of a drafting device such as a clearer roller, a suction device, a feeder guide for supplying a special roving, and a condenser. It is often desired to also arrange. It has already been proposed that the clearer roller holders be mounted together by mounting bolts on the top roller holder for mounting the clearer rollers.

[0003] German Patent DE 1010882 describes a system in which a clearer roller holder is provided on the outer wall of a top roller holder. In that case,
The outer walls on both sides of the top roller holder are covered so as to straddle the nose portion of the clearer roller holder.

[0004]

The above-mentioned known method has a drawback that it is necessary to increase the width of the top roller. Therefore, in many spinning machines, an automatic control component such as a yarn feeder guide swings closely to the side of the top roller holder, but a space for it cannot be secured. In addition, the various accessories provided must be individually adapted to the mounting scheme on the top roller holder.

It is an object of the present invention to avoid the above mentioned drawbacks and to make a top roller holder with standard locking for various draft device accessories.

[0006]

SUMMARY OF THE INVENTION According to the invention, the object is to provide a top roller holder of the type mentioned at the outset.
At least one of the recesses, protrusions, or holes on both side walls of the top roller holder to which adapter elements for various accessories including clearer rollers, suction devices, condensers, covers, feeder guides for special roving threads can be attached This is achieved by the provision of the locking portion formed in 1.

[0007]

[Advantageous Effects and Effects of the Invention] Since the top roller holder is provided with the engaging portions formed by the concave portions, the convex portions or the holes on both side walls, the accessory can be arranged at the engaging portions at any desired locations. Moreover, in cooperation with the adapter element, the top roller holder can be quickly and easily adapted to the requirements of the individual customer. Further, the spinning machine can be switched to another purpose without any problem by exchanging accessories.

The locking portion is provided in the form of an embossed recess or protrusion, and / or a hole, and is preferably arranged near the lower edge of the top roller holder, so that the accessory is in close contact with the draft plane, Therefore, it is closely attached to the place where it is arranged. For example, when the locking portion is provided by embossing, it is preferably provided on the inner side surface of the side wall so that the curved bulging portion is not formed on the outer side surface. The adapter element is inserted from below into between the side walls of the top roller holder having an inverted U-shaped cross section and is anchored to the embossed stop. To this end, the adapter element has a corresponding locking part formed as a convex or concave part by embossing for locking to a locking part located opposite to both side walls of the top roller holder. If the locking portion of the top roller holder is a hole, the corresponding locking portion of the adapter element will be a protrusion. In this way, the adapter element is simply attached in a pinning manner without protruding from the outer surface from the top roller holder. Therefore, the movement of the automatic control components, such as the feeder guide for the roving supply, is not hindered by the adapter element. The adapter element is advantageously made of a synthetic resin and can be swung in an emboss or bore. In this way, the swingability of the accessories arranged on the adapter element in the top roller holder is ensured. The diameter of the embossing or hole is 1.5 to 5 in order to avoid flying attachment of fiber waste.
mm is advantageous.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a top roller holder according to the present invention;

The top roller holder 1 shown in FIG.
0 is supported by a support rod 12 via a support 11. The holder 10 supports the pin 1 on the support 11.
3 can be swung about, for example, and can be flipped upward from the draft plane by means of a lever 14 to insert a new fiber bundle. Three top rollers 16 are provided on the lower surface of the top roller holder 10 via holders 15 respectively. A clearer roller holder 17 is provided at the front end of the top roller holder 10. To place other clearer rollers or condensers, covers, suction devices, etc., both side walls 20 of the top roller holder 10
A hole 19 as a series of locking portions is provided at a lower edge of each of them at desired intervals. An adapter element 21 shown in FIGS. 2 and 3 is fitted into these holes 19 from the inside of the top roller holder 10, for example to receive a clearer roller holder.

The adapter element 21 made of synthetic resin is
The locking projections 2 are provided at both ends to be fitted in the holes 19.
It has 2,23. These locking projections 22 and 23 can be locked in the holes 19 located opposite to both side walls of the top roller holder 10. In the adapter element 21, locking projections 22, 23 are provided on the webs 24, 25 on both sides, which webs 24, 25 on both sides are a thin transverse web 26.
Are elastically connected to each other. Both sides web 2
By simply compressing the locking projections 22, 25,
The adapter element 21 can be removed from the top roller holder 10 by removing 23 from the hole 19 again. The adapter element 21 is bent into a hook shape on both sides of the lower side surface, and elements 27 and 28 (FIG. 3) into which the clearer roller holder is fitted.
See). The shape of these elements 27, 28 can be changed if the adapter elements receiving the aspirator, cover, etc. are different.

Arranged embossing recesses, protrusions or catches 19 formed as holes are combined with the adapter element 21 to become standard for any accessory of various drafting devices. ing. In that case, the accessories of the drafting device can be mounted close to the draft plane, i.e. close to their placement on the top roller holder 10. And the space required to lock such accessories is extremely small.
