Description

[Detailed description of the invention] Industrial field of application The present invention removes residual yarn from the tail yarn wound around the tail yarn winding section at the bottom of the spindle of spinning machines, yarn twisting machines, etc.
This invention relates to a tail yarn remaining yarn processing device for a spinning machine that cuts the crossover yarn between a tail yarn winding section and a pipe yarn winding section.

Conventional technology Generally, when a spinning machine or a twisting machine automatically performs a tube change operation, after removing the full yarn from the spindle and inserting an empty bobbin into the spindle, upon starting the operation,
In order to wind the thread that has passed from the roller part through the traveler and is connected to the spindle onto the empty bobbin on the spindle, after forming a full thread, lower the ring rail and place a small amount of thread into the end winding section provided at the bottom of the spindle. Both have to be wrapped about 3 times.

It is known that the so-called tail thread remaining wound around the tail thread winding section is removed from the tail thread winding part every time the pipe is changed, and this does not affect operation and is relatively easy to remove. ing.

Conventionally, a large number of residual tail yarn processing devices and residual tail yarn processing devices for removing the residual tail yarn have already been proposed.

Most of the methods for processing residual threads that have already been proposed include a cutter device and a two-stage structure of a cutter and a brush.
For example, Japanese Patent Laid-Open No. 60-81336 and Japanese Patent Publication No. 81336 disclose a device in which the front side of the spindle row is moved from one end along the spindle row when the machine is in operation or stopped.

It is disclosed in No. 15614 and Utility Model Application Publication No. 53-41424.

Problems to be solved by the invention However, these conventional tail yarn residual thread processing devices and tail yarn residual yarn processing devices have advantages and disadvantages, and have not yet been adopted. Currently, the tail thread is cut after several tube changes and when the machine is stopped.

The reasons why the remaining tail thread processing devices proposed in the past have not been adopted are that the cutting mechanism is complicated and lacks reliability, and in order to move the spinning machine along the spindle row, two machines on the left and right sides are required per spinning machine. The problem is that the equipment cost is high because it requires processing equipment, and a high degree of precision is required for movement.Moving type spinning machines have a configuration that avoids the pantograph mechanism for toffing in the case of a spinning machine equipped with a simultaneous pipe change device. The mechanism is complicated because of the requirement for the following, and the brush that rubs against the heel winding part is subject to severe wear.Moreover, the movable type is dangerous during operation.

In consideration of the above-mentioned problems, the present invention is a sliding-type tail thread residual thread processor located at the rear of the spindle corresponding to each spindle, which does not require a cutter device and has a special brush configuration to be described later. By reciprocating several times during operation from the standby position, the crossover thread is cut and
To provide a tail yarn residual yarn processor for a spinning machine which can surely remove the tail yarn remaining wound around a tail yarn winding part and does not affect the processing even if a brush is worn to some extent. The purpose is to

Means for Solving the Problem In order to achieve the above object, the tail yarn residual yarn processor in the present invention comes into contact with the tail yarn winding part provided at the lower part of the spindle, and removes the tail yarn remaining by the rotation of the spindle. At the top of the front of the rubbing thread residual thread processor body,
A plurality of alloy brushes made up of a large number of alloy bundles are planted in parallel at intervals, and a plurality of synthetic fiber brushes made up of a large number of synthetic fiber filament bundles are placed below the alloy brushes. It has a spaced and planted brush configuration.

The tail yarn residual thread processor main body having the brush configuration described above is attached to a reciprocating sliding device, and the brush piece having the brush configuration is swingably supported by a supporting member, and the back side of the brush piece is Further, the other end of a coil spring whose one side is adjustable and latched to the support member is brought into contact with the support member, so that the brush piece is always resilient.

The alloy brush is preferably made of brass or phosphor bronze, which has a lower hardness than that of the end winding part, as these have excellent abrasion resistance. Furthermore, a bristle brush may be used instead of the synthetic fiber brush, but a synthetic fiber brush made of nylon is preferable because of its abrasion resistance.

The elastic force of the coil spring is adjusted in advance so that the brush piece is swung by the elastic force of the coil spring, that is, the contact force is about 30 to 40 g.

Function: The brush part of the main body of the tail thread residual thread processor is moved from the standby position at the rear of the spindle corresponding to the tail winding part provided at the bottom of each spindle group to the reciprocating sliding device to move the brush part of the main body of the tail thread residual thread processing device to the end thread forming part after the pipe change is completed. 3-5 times, 2-5 times while the ring rail does not interfere until the tube is full from approximately 3 minutes.
Let them come into contact for about 2 to 3 seconds at 3 second intervals.

An elastic contact force is applied due to the contact of the brush case of the main body of the tail thread residual thread processor mentioned above, and both brushes rub against the tail winding remaining thread, and this rubbing causes the alloy brush to cross. At the same time, the thread is cut and the remaining thread wrapped around the tail is removed using both brushes. This tail-wrapping remaining thread becomes small thread waste and is scattered.

Example Examples will be described with reference to the drawings.

In FIGS. 1 to 3, A is the main body of the tail thread residual thread processor, and the main body supports a brush piece 1 equipped with a brush portion B (configuration described later) at its tip so as to be elastically swingable. , consisting of a support member 4 whose rear part is attached to a reciprocating slide (not shown).

Brush portion B provided on the front surface of the brush piece 1
Above the upper part of the tail bobbin winding part, there is an alloy brush 2 in which a plurality of alloy bundles (3 to 4 bundles) are planted in parallel with intervals, and below the alloy brush. It is composed of a synthetic fiber brush in which a plurality of synthetic fiber filament bundles (5 to 6 bundles) are planted at intervals. The brush piece 1 has one end pivotally attached to the support member 4 by a headed pin 5. Reference numeral 6 denotes a coil spring supported by the supporting member 4. One end 6' is engaged with a plurality of holes 7 formed in the supporting member 4, and the other end 6'' is pressed against the back surface of the brush piece 1. 1 is configured to be always elastic.This elasticity is always 30
Adjust the position of the hole 7 that engages with one end 6' of the coil spring 6 so that the weight is about 40 g.

The brush part B of the tail thread residual thread processing device main body A having the above-mentioned configuration is made to face the rear part of the tail thread winding part 8 provided at the lower part of the spindle group, and the rear part of the support member 4 is connected to a suitable reciprocating sliding device ( (not shown).

The present invention is constructed as described above, and after the main body A of the tail thread residual thread processing unit A is started after the pipe change is completed, the ring rail does not interfere, and the length of the full pipe thread forming time is approximately 3 minutes. A reciprocating sliding device (not shown) for about 2 to 3 seconds, 3 to 5 times at intervals of 2 to 3 seconds, as appropriate.
The reciprocating motion causes the brush part B to slide back and forth and come into contact with the tail winding part 8. With this operation, brush piece 1
The alloy brush 2 and the synthetic fiber brush 3 are applied with an elastic contact force of

remove. This tail thread remains becomes small thread waste and is scattered.

Effects of the invention As mentioned above, in the present invention, the remaining threads of the tail thread wound around the tail thread winding part and the crossing threads are removed by rubbing with a brush, but the brush part is different from the conventional one. Since the alloy brush and the synthetic fiber brush are not closely spaced and are relatively coarsely planted in the brush piece, the removed remaining threads will not get tangled with the brush, and therefore the removal efficiency will not decrease. Since the brush piece is supported in the main body of the tail thread residual thread processor so as to be able to swing elastically, the processing operation is reliable even if the brush part is slightly worn, and even if there is some variation in each spindle weight. It can be used for a long time without any side effects. Furthermore, since the main body is attached to a reciprocating sliding device provided at the rear of the spindle, it does not get in the way and does not interfere with operation. Also, compared to the conventional type that moves along the spindle row, the structure is simpler, and by bringing the brush part into contact with the tail part 3 to 4 times, the crossover thread and the remaining thread of the tail thread can be quickly and reliably removed. It has the following effects:
