DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for shaping and cleaning a dropper for a stop motion used in a loom.

[0002]

2. Description of the Related Art As shown in FIG. 5, a stop motion dropper of a loom is used to detect a yarn breakage occurring during an opening operation of a warp a. The lower edge c of b and the hanger bar d repeatedly collide. Therefore, when the dropper A is used for a long time, the lower edge c of the hanger hole b is plastically deformed by the collision as shown in FIG. Become.

The glue that has fallen from the warp yarn a adheres to the lower part of the front and back surfaces of the dropper A due to moisture and the like, and after a long time elapses, as shown in FIG. The dropper A swells on the front and back surfaces.

The burrs e and the contaminated solids f are disadvantageous in that a device for separating the dropper A in the warp preparation step may cause a separation error. Needs to repair dropper A. For this reason, the burrs e and the contaminated solids f have conventionally been scraped off manually by using a file or the like.

[0005]

However, according to the above-mentioned conventional method, the operator must manually remove the burrs e and the solidified substances f of the stop motion dropper A by hand. However, there was a problem that a great deal of time and effort was required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a method and an apparatus for shaping and cleaning a stop motion dropper capable of automatically and efficiently removing the burrs and dirt solidified material.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, a method for shaping and cleaning a dropper for stop motion according to the present invention comprises first passing the dropper for stop motion between at least one pair of pressure contact rollers, and then at least one dropper. It is characterized by passing between a pair of brushes.

[0008] In order to achieve the above object, the stop-motion dropper shaping and cleaning apparatus of the present invention has at least one pair of pressure-contact rollers for passing the stop-motion dropper in a pressure-contact state, and has been discharged from the pair of pressure-contact rollers. At least one pair of rotating brushes for receiving and passing the stop motion dropper is provided.

[0009]

According to the method of the present invention, as shown in FIG. 1, first, the dropper A is connected to at least one pair of pressing rollers 1a,
1b, the burrs e (see FIG. 4) formed at one edge (lower edge) of the hanger hole of the dropper A can be crushed and removed, and at the same time, swell on the front and back surfaces of the dropper A. Stained solid f made of glue or the like (see FIG. 4)
Can be easily crushed and removed. Next, by passing the dropper A between at least one pair of brushes 2a and 2b, the dirt solidified material f is scraped off, and the front and back surfaces of the dropper A can be made smooth.

According to the apparatus of the present invention, as shown in FIG.
At least one pair of pressing rollers 1a, 1b and at least one
With the simple structure including the pair of rotating brushes 2a, the dropper A for stop motion can be shaped and cleaned automatically and efficiently. In particular, when transferring the dropper A from the pair of pressing rollers 1a, 1b to the pair of rotating brushes 2a, 2b, the pressing rollers 1a,
1b and the rotation of the rotating brushes 2a and 2b, so that a special transfer means is not required, and the width of the apparatus in the moving direction of the dropper A can be shortened to make the apparatus compact. .

[0011]

1 and 2 show an embodiment of the present invention. In the figure, 3 is a machine frame, 4 is a loading table for supplying a dropper A for stop motion, 1a and 1b are a pair of upper and lower pressing rollers, 2a and 2b are a pair of upper and lower rotating brushes, and 5 is a driving roller for driving a pressing roller. The motor 6 is a rotary brush driving motor.

The rotation of the pressing roller driving motor 5 is transmitted to the upper and lower pressing rollers 1a and 1b by a transmission means comprising chain wheels 7a, 7b, 7c and 7d and a chain 8.
These are rotated in the direction of the arrow in FIG. The shaft 9b of the lower pressing roller 1b is supported at a fixed position, while the shaft 9a of the upper pressing roller 1a is supported so that the vertical position can be adjusted. In FIG. 2, reference numeral 10 denotes a bearing for supporting the shaft 9a of the upper pressure roller 1a.
Determines the vertical position. In this way, the gap between the upper and lower pressing rollers 1a and 1b can be adjusted, and the pressing force applied to the dropper A when passing through the dropper A can be adjusted.

The rotation of the rotary brush driving motor 6 is transmitted to the upper and lower rotary brushes 2a, 2b by a transmission means comprising chain wheels 12a, 12b, 12c, 12d and a chain 13, and these are transmitted in the direction of the arrow in FIG. Rotate. The shafts 14a and 14b of the upper and lower rotating brushes 2a and 2b are supported at fixed positions, respectively, and the two rotating brushes 2a and 2b are positioned at such an interval that their tips come into contact with each other. The rotation speeds of the rotating brushes 2a and 2b are the same as the pressing rollers 1a and 1b.
It is larger than the rotation speed.

As shown in FIG. 1, a pair of pressing rollers 1a and 1b and a pair of rotating brushes 2a and 2b are disposed so that the dropper A can pass horizontally. Both are arranged close to each other so that the rotary brushes 2a and 2b can receive the dropper A carried out from the hopper.

Next, a description will be given of a method for shaping and cleaning the burrs e of the dropper A and the solidified matter f of the dropper A using the above apparatus.

The dropper A having the burrs e and the solidified solids f shown in FIG. 4 is placed on the carry-in table 4, and is pushed between the pair of pressing rollers 1a and 1b with the side having the solidified solids f at the top. Go. Then, the dropper A is sandwiched between the pair of pressing rollers 1a and 1b, and is transferred in the direction of arrow P while receiving the pressing force. Dropper A is a pair of pressure roller 1
While passing through a and 1b, first, the solidified material f such as the glue, which is rising on the front and back surfaces of the dropper A, is crushed and becomes a small piece to be easily removed. It is easy to be pressed down and returned to one edge c of the hanger hole b, or to be easily broken off.

Next, the dropper A moves from the pair of pressing rollers 1a and 1b to the pair of rotating brushes 2a and 2b,
While passing here, the solidified solid f that is easily removed by the rotating brushes 2a and 2b and the burrs e that are easily broken and detached are scraped off. The dropper A (see FIG. 3) from which the burrs e and the dirt solids f have been removed in this way is discharged from the rotating brushes 2a and 2b.

In the above embodiment, a pair of pressing rollers 1a,
1b and a pair of rotary brushes 2a and 2b are disclosed. However, it is preferable that a dropper A is provided with a plurality of pairs of pressing rollers and rotary brushes, and that the dropper A is shaped and cleaned. In practicing the method of the present invention, other types of brushes such as reciprocating brushes can be used instead of the rotating brushes 2a and 2b.

[0019]

According to the present invention, it is possible to provide a shaping cleaning method and a shaping cleaning apparatus capable of automatically and efficiently removing the burrs of the stop motion dropper and the solidified matter.
