Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a picker device for flying a shuttle in a loom, and more specifically to a structure of a picker and a picker retainer in the picker device.

[0002]

[Prior art]

 Conventionally, a loom has been designed such that a shuttle repeats a reciprocating flight across the warps in order to weave the wefts. The picker devices on both sides provided to fly this shuttle are structures in which the picker is guided by the spindle to reciprocate left and right by the swinging motion of the stick, and the shuttle picks up and strikes at the end face of this picker. It has become.

The action of receiving and flying the shuttle by the picker is called picking, but the picker inevitably has a floating action during the picking, and the picker tries to float. Conventionally, a picker retainer is provided to prevent this floating, but abrasion dust is generated when the picker and the picker retainer come into contact with each other, which gives a great disadvantage to the fabric in the loom.

That is, since the picker retainer is cast iron and the picker is a synthetic resin, the picker wears to generate wear debris, and since the picker moves quickly, the wear debris flies to the fabric in the loom and is woven into the fabric. Rarely, there is a problem in that woven fabric scratches due to the inclusion of foreign matter remain as a serious defect in the woven fabric.

Further, the contact between the picker and the picker foot is repeated averaging 30,000 to 40,000 times a day, so that the picker gradually wears and slips, and must be replaced in an average of 2 to 3 months. It also has the problem of not becoming.

[0006]

[Problems to be solved by the device]

 The present invention has been made for the purpose of solving the above-mentioned problems, wear debris does not fly during picking, and a woven fabric does not cause a defect due to weaving of the wear debris. The purpose of the present invention is to provide a picker structure for a new loom that can significantly extend the picker life.

[0007]

[Means for Solving the Problems]

 As a result of various studies to achieve the above object, a metal such as stainless steel that does not generate rust or a hard member such as hard ceramic is attached to the picker at the portion that comes into contact with the picker retainer. It was found that very good results could be obtained by attaching a relatively soft cover material such as synthetic resin to at least the part that comes into contact with the picker.

That is, according to the present invention, in the picker for flying the shuttle and the picker retainer for suppressing the lift of the picker at the time of picking, the picker portion with which the picker retainer is in contact has wear resistance and rust resistance. And a picker structure for a loom, characterized in that a relatively soft cover material such as synthetic resin is attached to at least a portion that comes into contact with the hard member on the picker retainer. In addition, it was created even more suitable if both ends of the picker position where the picker presser comes into contact with the upper surface were cut.

The present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an outline of a picker device according to the present invention. As shown in the figure, the picker device swings through a picker (1) installed to reciprocate along a shaft (s) of a spindle and a central hole (2) of the picker (1). It is composed of a stick (3) and a picker retainer (4) for preventing the picker (1) from floating during picking.

In other words, the swinging motion of the stick (3) while penetrating the central hole (2) of the picker (1) causes the picker (1) to reciprocally move, and the end surface of the picker (1) (see FIG. Pick the shuttle at the point (opposite the t position). The picker retainer (4) prevents the picker (1) from floating during this picking. The picker retainer (4) is fixed to the frame (f) via the arm (5).

FIG. 2 is a perspective view showing only the picker according to the present invention. FIG. 3 is a side sectional view showing an essential part of the present invention. As shown in these figures, in the present invention, the picker (1) is provided with a hard member (6) and the picker retainer (4) is provided with a cover material (where 7) are attached respectively.

The hard member (6) is made of a material having wear resistance and rust resistance, most preferably stainless steel or other hard ceramic material, and its mounting means is a screw (8) as shown in the figure. Then, the head of the screw may be fixed so that it does not protrude to the surface, or other bonding means or insert processing means may be used. It is preferable that the surface of the hard member (6) is slightly raised (2 to 4 mm) more than the surface of the picker (1).

On the other hand, the cover material (7) attached to the lower end portion of the picker retainer (4), that is, the portion in contact with the hard member (6) is preferably made of a relatively soft material such as synthetic resin. In the experiments conducted by the present inventor, excellent results were obtained with ultra-high molecular weight polyethylene resin. In addition to synthetic resin, leather, hard rubber, wood, etc. can be used as the material of the cover material (7). Further, it goes without saying that the means for attaching the cover material (7) may be screwing, bonding, or any other means.

As shown in FIGS. 1 and 2, when the picker retainer (4) is in contact with the picker position, both ends of the picker retainer (4) are cut to the upper surface (9), and more preferable results are obtained. Will be things. In other words, even when the picker (1) floats up and down to the left and right, if both ends of the picker (1) are in the upper surface cut (9) state, the surface of the picker (1) directly touches the picker retainer (4). There is no contact with.

[0015]

[Action]

 The present invention is configured as described above, and the contact between the picker (1) and the picker retainer (4) at the time of picking is the contact between the hard member (6) and the cover member (7). Since 6) has abrasion resistance, it does not wear, and therefore, no abrasion debris from the picker (1) is generated, and as a result, no abrasion debris is woven into the woven fabric as in the conventional case. Weave defects are gone. Further, since the hard member (6) has rust preventive properties, rust does not occur and it can be used for a long period of time.

Further, since the hard member (6) is present, the picker (1) itself is not worn away due to wear, and the usage period thereof can be greatly extended. The prototype of the present invention (stainless steel for the hard material and ultra-high-polymer polyethylene for the cover material) is currently being contacted about 40,000 times a day for 9 months, but it shows almost no wear. It is predicted that the product will have a service life of more than one year, and the frequency of replacement is very low compared to the conventional two to three months, which has a great effect on the time and material cost for replacement. As described above, it is more preferable to form the upper surface cut (9).

By the way, the reason why the cover material (7) is attached to the picker retainer (4) is that if the cover material (7) is not present, this material is cast iron, so this is directly connected to the hard member (6). This is because they come into contact with each other, or metal and ceramic come into contact with each other, and defects such as fireworks and damage are likely to occur. Therefore, the cover material (7) is attached, but it has been found that abrasion debris does not fly even if the cover material (7) is a synthetic resin.

It is considered that the reason is that the picker retainer (4) is fixed, so that even if it wears, the abrasion debris does not fly to the fabric position. In other words, when the picker (1) wears, it moves at high speed and its inertia causes the abrasion debris to fly to the fabric position, but even if the abrasion occurs from the cover material (7) of the picker retainer (4). Because it is fixed, it does not fly much.

[0019]

[Effect of device]

 The effects of the present invention are as described in detail in the action column, and are summarized as follows. (A) Even if the picker and the picker retainer come into contact with each other, the abrasion debris does not fly, the abrasion debris is not woven into the woven fabric at all, and the fabric defect caused by the abrasion debris does not occur. (B) The picker can be used for a long period of time, the time and effort required for replacement are reduced, the resource is saved, and the material cost is reduced. As described above, the present invention exhibits a high degree of utility in the manufacture of textiles.
