Description

The invention relates to the glass industry, in particular to devices for breaking glass pipes obtained by the method of vertical drawing.

A device for breaking glass pipes obtained by the method of vertical drawing, containing made with the possibility of rotation in the vertical plane of the beam Yu with a grip equipped with prismatic stops and an electromagnet [ΐ].

The disadvantage of this device is the low quality of the fragments resulting from the large force 15 of the clamping prismatic stops.

The closest technical solution to the invention is a device for breaking glass pipes obtained by the vertical method of pulling, containing a frame with a beam mounted on it with the possibility of rotation in a vertical plane with a grip and support

The disadvantage of this device is the low quality of the fragment resulting from scratching the pipe by contact elements and the thickness of the pipe caused by bending it in the production chamber, 30

The purpose of the invention is improving the quality of the fragments.

This is achieved by the fact that in the device for breaking glass pipes obtained by the method of vertical drawing, containing a frame with a beam mounted on it with the possibility of rotation in a vertical plane with a grip and a stop, the grip is made in the form of two consoles with rollers and a lever with a roller placed between them moreover, all the rollers are made with ratchet mechanisms and are located at the vertices of an isosceles triangle with a base parallel to the axis of the beam, mounted with the possibility of rotation by an angle of 100-105 °, and the emphasis is equipped with a supporting roller Ikom.

Figure 1 shows a General view of the device; figure 2 is a side view.

The device includes a frame 1 on which a beam 2 is mounted. The beam 2 is mounted with the possibility of rotation from the drives 3 and 4 in a vertical plane at an angle c / = 100-105 °.

The rotation of the beam 2 is carried out using a gear rack 5 and gear 6. The axis of the gear 6 is rigidly connected to the beam 2.

In the upper part of the beam 2 there is a grip consisting of the upper 7 and lower 8 fixed consoles and the middle cantilever lever 9 connected to the actuator 10.

At the ends of the consoles 7 and 8 and the cantilever arm 9, the rollers 11 are reinforced. .12,13 with ratchets 14,15, and 16. The axes of the rollers 11,12 and 13 are located at the vertices of an isosceles triangle, the base of which is parallel to the axis of the beam 2 and is 2-3 pipe diameters 17. The ratchet mechanisms 14,15 and 16 provide the rotation of the rollers 11,12 and 13 in only one direction (when the pipe 17 moves up) and prevent their reverse rotation.

The vertical axis of the capture is offset relative to the axis of the beam 2 by a distance equal to δ.

In this case, = 1.1-1.8, where 8 is the diameter of the pipe. ^{r p}

When the distance is less than 1.1, it is not possible to lay the glass pipes 17 directly on the guides (not shown in the figures), and an increase in the distance of more than 1.8 makes it necessary to increase the angle of rotation of the beam 2.

A stop 18 with a cantilever support roller 19 is mounted on the front surface of the frame 1.

The device operates as follows.

The glass pipe 17, when pulled, moves up and turns on the sensor (not shown in the Figures), which gives a command to actuate the drive 10 of the gripping mechanism and the actuators 3 and 4 of the beam turning mechanism 2.

A movable cantilever lever 9 with a roller 13, moving to the rollers 11 and 12, clamps the pipe 17. Then the beam 2 begins to rotate in a vertical plane. When the beam 2 is rotated, the pipe 17, sandwiched by the rollers 11,12 and 13, starts to rotate in a vertical plane and abuts against the support roller 19 by the side surface. At the same time, the pipe 17 continues to move upward in the vertical plane. The rollers 11,12 and 13 of the gripping mechanism do not impede the upward movement of the pipe 17.

Ζ at the beginning of the turn of the beam 2, the cut line previously applied to the surface of the pipe 17 is installed coaxially with the support roller 19. With a further turn of the beam 2, the pipe 17 breaks off along the cut line.

A piece of pipe is moved by a beam 2 with a capture from a vertical to a horizontal position. Turning beam 2, at the end of the path it turns on the sensor giving a command to turn off the drive 10 of the gripper mechanism and the drives 3 and 4 of the beam swing mechanism 2. These commands are given 5-6 ° before the beam 2 passes the horizontal position.

Since the vertical axis of the capture is offset relative to the axis of the beam 2, the guides on which the pipe 17 is laid are on both sides of the capture when it is horizontal.

> When approaching the horizontal position, the pipe 17, released by the rollers 11,12 and 13, remains on the guides. Beam 2 with a grip continues to rotate in a vertical plane at an angle of 100-105 °. In this case, the extreme upper points of the rollers 11 and 12 are installed below the lower generatrix of the pipe 17 lying on the rails. After that, the pipe 17 rolls down along the guides.

When the pipe 17 is turned, the ratchet mechanisms 14,15 and 16 of the rollers 11,12 and 13 do not allow the rollers to rotate in the opposite direction, which prevents the pipe 17 from falling down.
