Description

A machine for wrenching mittens and other similar products is known, comprising a rotatably mounted table with supporting tubular mandrels for putting on mittens on it and movable mandrels coaxially arranged above them. The latter are periodically inserted into tubular mandrels for wrenching mittens by means of an actuator.

The proposed machine is equipped with a device for removing and withdrawing from the working area an inverted pair of mittens, which is made in the form of grippers with rollers moving in horizontal guides, entering the grooves of the head, located in vertical cylindrical guides. These guides are rigidly fixed on the brush, which rotates synchronously with the turntable.

The drive for the reciprocating movement of the movable mandrels and grippers in the vertical plane is made in the form of a Krivoschipno-rod mechanism, kinematically connected with an electric motor. To periodically rotate the turntable, a spring-loaded finger is mounted on the curved wheel, which in turn interacts with the pins fixed to the table.

Kami wedges mi, providing removal of mittens from mandrels when interacting with the lower wedges mi and dropping them - when interacting with the top. The support mandrels are mounted in pairs for simultaneous removal of a pair of mittens.

The proposed machine is more productive compared to the known, as it provides simultaneous twisting of the pair.

connected mittens.

FIG. 1 shows the kinematic scheme of the proposed machine; in fig. 2 - a device for removal and removal from the working area of an inverted pair of mittens.

The machine comprises a rotary table / with supporting tubular mandrels 2 mounted on it in pairs for donning mittens. Above the mandrels are coaxially arranged movable mandrels 3 for twisting the mittens. On the bottom surface of the table

The pins 4 are reinforced along the circumference and a hole 5 is made to enter it, and the podrul of the non-retaining latch 6 is inserted into it.

The table / is a gear that engages with bristles 7 rotating synchronously with the table.

For removal and removal of the working area of the twisted pair of mittens, the machine is equipped with a device mounted on the brush

rollers 9 and 10. The grippers are positioned between horizontal guides 11 and 12. which fit into the grooves of the head 13, which is located in vertical cylindrical guides 14 rigidly mounted on the gear wheel 7. Guides 14 are provided with upper and lower wedges 15 and 16.

The head 13 is connected to a rod 17 located inside the cylindrical guides 14 and rigidly connected to a slider 18, on which movable mandrels 3 are placed.

The drive for the reciprocating movement of the movable mandrels 3 and the grippers 8 in the vertical plane is designed in the form of a rod 19 and a crank 20 fixed on the shaft of the worm gearbox 21. On the same shaft there is a fist 22 interacting with the roller 23, which is connected by a lever -forks 24 with lock 6.

The crank 20 has a swinging drive pin 25 held by a spring 26 and an anvil 27 in a position perpendicular to the crank 20. The gearbox 21 is driven by the electric motor 28 and the belt transmission 29.

The machine works as follows.

Outside the working area of the movable mandrel 3 on the supporting mandrel 2 put on a pair of connected mittens.

From the electric motor 28, the crank mechanism and the cam 22 are driven, which, by means of the roller 23 and the fork lever 24, removes the retainer 6 from the opening 5 of the turntable. The table released from the retainer is rotated by the finger 25 when interacting with one of the pins 4. At the beginning of the table movement, the cam 22 releases the roller 23, and the clamp 6 under the action of the spring 30 rests on the lower surface of the table without preventing its rotation.

When the hole 5 approaches, the retainer 6 drops into it and stops the table in a position when the mandrels 2 with mittens are in the working area under the movable mandrels 3. With the table position fixed, the movement of the crank-connecting rod mechanism with the leading pin 25 continues, which, devi expands the spring 26 until it disengages from the pin 4. The pin 25 returns to its original position by the spring 26 and the stop 27.

When the connecting rod 19 moves, the slider 18 is lowered together with the rod / 7 and the head 13 with grippers 8. During this movement, the rollers 9 interact with the lower wedge 16

the guides 8 and the grippers 8 are inserted into the gap between the mandrels 2. When lifting the movable mandrels 3, the stem 17 is raised together with the grippers 8, during which the mittens are removed from the mandrels 2 and simultaneously turned out.

Upon further rotation of the table, gear 7 is rotated along with guides 14 and grippers 8, which continue to lift. In this case, the rollers 10 interact with the upper wedge 15, the grippers 8 are moved to the initial position, and the mittens are dropped from the grips.
