Then, the spring 6 is compressed by the compressed air, the piston 5 is moved to the tip of the shaft body 2, the elastic ring 4 is returned to its original shape, and is separated from the inner surface of the bobbin to release the grip on the bobbin. Further, a disc 9 of a brake mechanism 8 for quickly stopping the rotation of the shaft body 2 is provided at the support side end of the shaft body 2.
A brake shoe 10 is attached to the machine frame 1 by a bracket 11 to apply the brake by pressing the disc 9 from both sides. Further, the above-mentioned shaft body 2 is rotated by an integrally formed motor or the like, or by a surface pressure applying roller or the like. (Problem) In the bobbin gripping device as described above, the bobbin is
When inserting and gripping the compressed air supply pipe 3, operate the electromagnetic switching valve 32 of the compressed air supply mechanism 30 to switch the supply path
At the same time as stopping the supply of compressed air from 5 and 36, compressed air is supplied from the compressed air supply pipe 34 to the compressed air chamber 33c of the cylinder 33 to retract the piston rod 33a. Then,
The compressed air supplied into the hole 2b of the shaft body 2 instantly
It is discharged from the end. At this time, the compressed air flows through the hole 2b of the shaft body 2.
When it flows out, it collides with the end face of the piston rod 33a, and flows out in the radial direction from the gap between the shaft body 2 and the piston rod 33a. And disc 9 of brake WAJtf48
The problem is that the abrasion powder of the brake shoes adhering to the brake shoe 10, etc., is blown away and scattered.As a result, the abrasion powder of the brake shoes scattered on the tip side of the shaft body 2 causes dirt on the Pa-7 gauge. was there. (Purpose) The purpose of the present invention is to prevent thread staining due to scattering of brake shoe abrasion powder etc. generated during bobbin gripping operation. (Means for Solving the Problems) In order to achieve the above-mentioned object, the bobbin gripping device for a winding machine of the present invention has a cylindrical body fitted into a shaft body rotatably mounted on a machine frame, and An elastic ring is interposed between the step part of the cylinder and the shaft, and the cylinder is moved to the shaft by a spring attached to the tip of the shaft or compressed air from a compressed air supply mechanism installed at the end of the shaft. In a device that grips the bobbin by pressing it against the step side so that the elastic ring extends in the diametrical direction, and also stops the rotation of the shaft body by a brake mechanism installed at the end of the shaft body. A valve for rapid discharge of compressed air is installed in the pipe that discharges the compressed air supplied to the shaft. In addition, a piston movement speed control valve may be installed in the compressed air supply pipe for operating the compressed air supply cylinder of the above-mentioned compressed air supply structure a, or alternatively, a piston movement speed control valve may be installed in the compressed air supply pipe for operating the compressed air supply cylinder of the compressed air supply tank. This can also be done by installing electromagnetic switching valves in the pipes that supply and discharge compressed air to the shaft body, and staggering the switching timing of each electromagnetic switching valve. (Example) The configuration of an embodiment of the bobbin gripping device of the winder of the present invention will be explained based on the drawings. !r48's elliptical precepts are the 4th.
Since the configuration is the same as that of the conventional bobbin gripping device shown in the figure, the explanation will be omitted, and the compressed air supply mechanism section will be explained. In the figure, l5 is a compressed air supply 'R installed at the end of the shaft body 2.
16 is a cylinder attached to the machine frame 1 by a bracket 11. 18 is an electromagnetic switching valve;
Main pipe 17 for compressed air supply on one side, pipe 19 for compressed air supply on the other side
, 20 are connected. Further, a hole 16b is bored in the piston rod 16a of the above-mentioned cylinder 16, and a compressed air supply and discharge pipe 2l having a quick exhaust valve 22 is connected to the hole 16b.
The other end of the pipe 21 is connected to a compressed air supply pipe 20. The above-mentioned rapid exhaust valve 22 has a cross-sectional area of the compressed air passage in the valve R of the exhaust valve that is larger than that of the electromagnetic switching valve 18, and has a top-height structure with low flow resistance. Further, the quick exhaust valve 22 needs to be installed at a remote location so that compressed air is not discharged toward the brake mechanism 8. When the above-mentioned compressed air supply mechanism 15 supplies compressed air to the hole 2b of the shaft body 2, the electromagnetic switching valve 18 is operated to supply compressed air from the compressed air supply pipe 20 to the cylinder 16, and the piston rod 16a is caused to protrude. It is connected to the end face of the shaft body 2, and supplies compressed air into the hole 2b of the shaft body 2 from a compressed air supply/discharge pipe 21 having a quick exhaust valve 22 and a hole 16b of the piston rod 16a. Next, when discharging the compressed air supplied into the hole 2b of the shaft body 2, the electromagnetic switching valve 18 is operated to switch the supply path, stop the supply of compressed air to the compressed air supply pipe 20, and at the same time Supply compressed air to service pipe 19. Then, the pressure in the pressure chamber 16c in the cylinder 16 becomes lower than the pressure in the pressure chamber 16d.
When the pressure in the pressure chamber 16c becomes equal to the pressure in the pressure chamber 16c, the pressure in the pressure chamber 16d is pushed out, and the piston rod 16a is retracted and separated from the end surface of the shaft body 2. During the period from the above-described switching operation of the compressed air supply position until the piston rod retracts, the compressed air that had been supplied into the hole 2b of the shaft body 2 is discharged from the rapid exhaust valve 22, and almost no compressed air is left. .

4 or as shown in FIG.
It is also possible to connect the electromagnetic switching valve 25 to the piston rod 16a of the cylinder 16 after most of the pressurized air in the hole 2b of the shaft body 2 is exhausted, but in this case as well, the piston rod 16a of the cylinder 16 can be moved from the brake m mechanism 8. It is necessary to ensure that the compressed air is discharged to a remote location. Furthermore, the present invention can also be implemented with a configuration in which a quick exhaust valve is connected to the compressed air supply/discharge pipe 21 shown in FIG. (Effects of the Invention) The bobbin gripping device of the winding Tl machine of the present invention has a cylindrical body fitted into the shaft body which is rotatably attached to the machine frame, and an elastic ring between the cylindrical body and the stepped part of the shaft body. The elastic ring is moved in the diametrical direction by pressing the cylindrical body toward the step side of the shaft body using a spring attached to the tip of the shaft body or compressed air from the top of a compressed air supply machine installed at the end of the shaft body. In a device that grips a bobbin by protruding from the shaft and stops rotation of the shaft by a brake mechanism installed at the end of the shaft, the compressed air is connected to a pipe discharging the compressed air supplied to the shaft at the top of the compressed air supply machine. Since a rapid discharge valve is installed, the abrasion powder of brake shoes and the like adhering to the brake machine slide is not blown away, so that thread contamination caused by the abrasion powder can be stopped.
