Description

Air piston structure for gripper of spinning machine

The present invention relates to an air piston structure for a gripper of a spinning machine, and more particularly, bobbin when the bobbin is seated at a predetermined position of the spinning machine in order to wind the bobbin (bobbin) or when the bobbin wound with the thread is taken out from the spinning machine. The present invention relates to an air piston structure for a gripper of a spinning machine to reduce the number of parts constituting a gripper for pressing and supporting an upper end portion.

As shown in FIGS. 1 and 2, the gripper structure for bobbin transport for a spinning machine according to the prior art includes an air supply line and a main body which is moved up and down within a predetermined stroke range due to driving of a predetermined moving unit. The body 2 is fixed to a predetermined shape with respect to 1), and an annular protrusion 3 is symmetrically formed on both sides of the front surface of the body 2, and the air inlet 4 communicating with the air supply line described above is the body. It is formed on the left and right sides of (2), and receives the bobbin (5) upper end when the main body (1) is lowered in accordance with the above-described driving force of the shank, at this time, the bobbin (5) is formed in a cone shape so that it is easily received by sliding The guide 6 is detachably coupled to the protrusion 3 by a predetermined fixing means, and the pressure member 7 which press-supports the upper end of the bobbin 5 when pneumatically injected through the air inlet 4 is provided with the protrusion ( 3) It is housed inside.

At this time, the fixing means described above, the grooves formed on the inner circumference of the guide (4) described above so that the locking jaw (8) formed on the outer periphery of the protrusion (3) and the engaging jaw (8) detachably coupled ( 9).

On the other hand, the above-described pressing member 7 is coupled to the rear of the body 2, the air moving hole 10 is formed therein and communicates with the air moving hole 10 is formed in the projection (3) The tube 12 having a predetermined shape in which the air discharge hole 11 is formed and the protrusion 3 are accommodated inside the bobbin 5 when the air pressure is injected through the air inlet 4. The air piston 13 for crimping and supporting, the elastic member 14 mounted on the air piston 13 and elastically biased to an initial state in which the clamping state for crimping and supporting the air piston 13 is released, and the air piston ( 13 and the tube 12 is provided with a diaphragm (15) to pressurize the air piston 13 toward the guide 6 when the air pressure is injected through the air inlet (4).

Therefore, as shown in FIG. 2, when the bobbin 5 is pulled out against the spinning machine or the bobbin wound around the yarn is taken out from the spinning machine as shown in FIG. Is located in the upper portion of the bobbin (3) to move in the lower direction in the drawing, in this case the air inlet 4 formed on both sides of the body 2 so as to be connected to the air supply line of the main body 1 and the air moving hole communicated with the As air pressure of a predetermined pressure is introduced into the tube 12 through the air 10, the air is discharged to the guide 6 through the air discharge hole 11 communicating with the air moving hole 10 in a direction perpendicular to the air moving hole 10.

Accordingly, the diaphragm 15 mounted between the tube 12 and the air piston 13 is pressurized toward the guide 6 by air pressure, and the air piston 13 moves due to the pressurization of the diaphragm 15 to bobbin. (5) The outer circumference is pressed to support the compression.

At this time, when the mutual center of the guide 6 and the bobbin 5 detachably coupled to the protrusion 3 of the body 2 is shifted, the guide 6 is separated from the protrusion 3. That is, from the locking projection 8 formed on the outer periphery of the protrusion 3, the locking state in which the groove 9 formed on the inner periphery of the guide 6 is coupled is released.

Therefore, as described above, the mutual center of the guide 6 and the bobbin 5 does not coincide with the bobbin 5 when the main body 1 is moved when the bobbin 5 is settled with respect to the spinning machine or withdrawn from the spinning machine. When the guide 6 is separated from the body 1, the guide 6 is used by recombining the protrusion 3 of the body 2 or when the guide 6 is broken when the guide 6 is broken. The bay will be replaced and reused.

However, the air piston 13 forming the pressing member 7 has a separate rubber material 16 to prevent the bobbin 5 from slipping when pressing and supporting the bobbin 5. The cost is increased due to the increase in the number of parts as it is coupled to the coupling groove 17 formed in the 13), and as the above-described air piston 13 is formed separately from the diaphragm 15, these are projected portions of the body (2) (3) In the case of inward coupling, these components are easily detached from the engaging portion inside the protrusion 3, which causes a problem in that workability is greatly deteriorated due to the increase of labor.

Accordingly, an object of the present invention is to provide a gripper air piston structure for a gripper that can reduce the number of parts constituting a gripper for pressing and holding the bobbin upper end for the spinning machine due to the air pressure supply to significantly reduce the cost cost.

Another object of the present invention is to provide an air piston structure for a gripper of a spinning machine, which can greatly improve workability by reducing work time for assembling a gripper for a spinning machine.
