Device for removing yarn residues from spinning tubes

The innovation relates to a device to remove yarn residues from spinning tubes, which device a number of mutually movable, set up in a frame, for gripping the sleeve below the one to be removed Claws formed by yarn remnants, as well as one set up above these claws perpendicular to the plane of the claws movable punch, by means of which the sleeve can be pushed through between the claws, comprises. Such a device is in the American patent 1 805 452. This known device is provided with two jaws that can move relative to one another in a horizontal plane, between which the jaws to be cleaned Sleeve is clamped. However, this known device is not suitable for cleaning different diameters having sleeves suitable; Sleeves with a small diameter are insufficiently detected, while sleeves with a larger one Diameter of the remaining yarn only at a few points, namely at the point of transition between the recess in the Claw and the flat part of the same, is supported, in addition, the distances between these points and the center of the bowl are not are the same.

The object of the innovation is to create a device of the type mentioned above that is not burdened with these defects and by means of which sleeves of different diameters can be cleaned, x-jobei the yarn package in a sufficient number is supported by points. The innovation also aims to create a very reliable one that is easy to build Device in which there is also a safety device for the operating personnel.

According to the innovation, at least three in radial direction movable claws provided with

The device is preferably provided with a double-acting pneumatic cylinder for driving the ram and the like Provided cylinder for driving the claw mechanism, the latter cylinder directly from one of the control member the device coupled three-way valve is controlled, which is used to operate the device compressed air to behind the piston this cylinder allows and connects the space in front of the piston with the outside air, while the pressure in the cylinder of the Piston from a three-way valve operated by a diaphragm control element is controlled which diaphragm control element, when the claws grip the sleeve and when the pressure for the piston in the cylinder actuating the claws drops below a certain value, this valve controls in such a way that compressed air above the piston driving the plunger.

The actuated by the locking ring control member can be a direct connection between the compressed air supply and of the operating membrane, whereby the piston driving the plunger returns to its upper position.

The innovation is explained below using the drawing.

Pointing to the drawing

Fig. 1 shows a cross section of the device according to the innovation,

Fig. 2 is a plan view of the claws and their operating mechanism,

Fig. J5 is a schematic representation of the pneumatic control circuit .

As shown in Fig. 1, the machine consists of a frame 1, which is supported with the legs 2 on the ground. The frame supports an upright part ~ 5 to which the pneumatic cylinder 4 is connected. The piston 5 is guided in this cylinder 4; the piston rod 6 fastened to the same carries the punch 7.

In the frame 1, the claws 8 are arranged with their operating mechanism. As can be seen in Fig. 2, four claws 8 made of nylon are connected to the pressure members 9, which are guided in corresponding radially directed grooves 10 provided in the fixed ring 11. Each pressure member is provided with an upright pin 1 which fits into a slot 15 extending from the outer circumference in the direction of the inner circumference of the ring 14 arranged above the pressure members. Mistake. The rotation of the ring 14 will therefore result in a radially directed movement of the pressure members 9 and the claws 8 attached to them. The circumference of the ring 14 is connected to the piston rod 15 which is connected to the piston 16 of the pneumatic cylinder VJ .

The claws 8 should with a certain pressure on the circumference of the to be cleaned sleeve 18, from which the remainder of yarn 19 is to be stripped off. For this purpose, the sleeve l8 of

Hand inserted between the claws 8 and by means of a control member to be described below, the "device set in motion. Here, air is allowed in the cylinder 17, whereby the ring 14 is rotated so that the four Claws 8 radially inwards - are offset. You grasp the sleeve 18 at four points on the circumference and only when this sleeve is held with a certain force, the operating mechanism switches on the cylinder 4, whereby the piston 5 with piston rod 6 and punch 7 move in the downward direction moves and takes the sleeve 18 with it during the last part of its stroke. The remainder of the yarn 19 remains behind Claws 8 and is thus stripped from the sleeve during the downward movement of the punch 7.

A ring 20 is provided over the top plate 2 of the frame, which is attached to the vertical rod 21, which is movable in the longitudinal direction in the on the upright half cylinder 3 mounted axle bearings 22 and 2j5. A protruding plate 24 fixed between the end of the rod 21 and attached and the upper side of the journal bearing 2J arranged around the rod Compression spring 25 holds this ring in its upper position. If you hold your hand when inserting the sleeve into the machine does not withdraw in time, it will be pinched between the punch 7 and the ring 20 when the machine is in operation whereby the ring 20 is also moved in the downward direction and the cam 26 attached to the rod 21 is the safety valve 27 actuated, which steers the pneumatic circuit in such a way that the piston 5 is moved in the upward direction and the Claws 8 come off.

The device is set in motion by means of a footstep 28 which is attached to the legs 2 and actuates a pneumatic valve 29. The action of this valve and the construction of the hydraulic circuit are shown in Fig. 3. The compressed air is supplied to the pneumatic circuit via connection 30. The compressed air inlet 30 is connected to the connection 29a of the valve 29 via the regulator J> 1, behind which the pressure gauge indicating the working pressure of the cylinder operating the claws is connected. In the rest position, this valve produces the connections shown in the figure in solid lines; In the working position, the connections indicated in the figure in dashed lines are established.

In the rest position, the compressed air inlet 29a is connected to the connection 29b leading to the connection 17a of a space located on the left side of the piston of the cylinder YJ. The connection 29c of this valve 29 is in communication with the outside air; the connection 29d connected to it in the rest position is in connection with 17b of the cylinder YJ . The space on the left side of the piston 16 is under pressure; in the rest position, the piston is therefore in its outer right position, the ring 14 being rotated in such a way that the claws 8 are as far apart from one another as possible. The connection 17a is also connected to the connection ~ $ \ a. the diaphragm chamber 31 in communication, whereby the diaphragm J2, to which the operating rod 33 of the valve ~ $ K is attached, is kept pressed in its lower position. As a result, the valve J> k remains in the position shown; in this position is the connection 34a with the connection J) K ¹ D and the connection

- 5a-

J4c is connected to port 3kd .

Since the connection ^ 4a via the regulator ^ 5 with the compressed air line is connected, the space is under the piston 5 in the operating cylinder 4 under pressure; the space above the piston 5 is in communication via the connection 4b and the valve connection j? 4d-54c with the outside air. The piston 5 will therefore be in its upper position.

The device works as follows:

By pressing in the kick step 28 one obtains the in dashed lines Lines shown connections between the ports of the valve 29 · This means that the space on the right side of the piston 16 via the connection 17b-29d and the valve connection 29d-29f is pressurized while the space on the left side of the piston 16 is in communication with the outside air via the connection 29b-29e. the Piston 16 moves to the left, causing the jaws to close. Temporarily remains on the left side of the piston l6 and maintain a certain pressure over the membrane 52, because the air cannot escape quickly through the lines and the valve. This will prevent valve J4 switched immediately.

When the piston 16 no longer moves because the claws 8 press against the sleeve, the pressure on the left side of this piston and above the diaphragm 32 drops.As soon as this pressure has dropped below a certain value, the valve 3 ^ switches over, whereby this valve makes the connections indicated in the figure in dashed lines. Compressed air is supplied to the space above the piston 5 via the regulator 35> to which the pressure gauge is also connected, and the connection 3 ^ e-3 ^^ es valve 3 ^, while the space below the piston via the connection 3 ^ b - 3 ^ f is in contact with the outside air. The piston 6 moves downwards and, via the piston rod 6 and the punch 7, presses the sleeve through between the claws. After releasing the kick 18, the whole thing returns to its rest position.

The safety valve 27 to be actuated by the rod 21 is inserted into a connection between the pressure line and the connection 17a of the cylinder 17. Closing this valve has the consequence that in the space above the membrane 32 again a pressure prevails, whereby the membrane is pressed in and the valve 3 ^ · <äie in the figure in solid lines the connection shown. As a result, the piston 5 immediately moves upwards again.

As can be seen from the above description, the innovation creates a simple, reliable machine for removal of yarn remnants from spinning tubes, which can process a wide variety of tube types. According to the simple structure the whole thing is very reliable, while because of the simple operation the speed with which the sleeves are removed can be increased considerably compared to the known method.
