Description

(54) DEVICE FOR CUTTING PEARS OF BRUSHES

one

The invention relates to the industrial use of building materials, in particular, to machines for moving dried brick when mounted on kiln tunnel trolleys.

A device for tipping round dried bricks is known, which contains a sector tilter of reciprocating motion, which works in conjunction with conveying mechanisms-conveyors 1.

This device does not provide high1: .h performance, since continuous tilting is impossible on the same transport mechanism. This disadvantage limits the field of application of the device and its technological capabilities.

The closest technical solution is a brick tilting device containing a rotary tilter and kinematically

associated transport mechanism 2.

This device has a higher performance, but it does not ensure the accuracy of the tilting operation on the same transport mechanism.

The purpose of the invention is to expand the technological capabilities of the device by providing tilting bricks on the same transporting flow mechanism, npprmer on a drive roller table.

Claims (2)

IS by the fact that a device for turning over a group of bricks, containing a drive roller table and a group tilter with an individual drive mounted between its rollers, is equipped with a tilting mechanism made in the form of a crossbar mounted in guides, on which a number of levers are hinged. They share a common gear on their gears, while the tilter is made in the form of L-brackets hinged on the levers, connected by gears, and the drive is equipped ulachkom-crooked spine kinematically communication zann m ry chagami and crossarm. Figure 1 shows the device, a view in plan; figure 2 is a section of LA in figl; Fig. 3 shows the operation of the cantor (positions a, b, 5, tj) The device for tilting groups of bricks contains a drive roller table 1, on rollers 2 of which groups of bricks 3 are installed with a certain interval. The tilter 4 is mounted between the rollers of the roller table. The L-shaped brackets 5 are connected to the mechanism of movement of the tilting device, which is complete in the form of 6 levers 7, which are hinged on the cross bar, carrying on themselves 8. The gear 8. which ensures exact position of the crown 5 at a certain time. The levers 7 are displaced with each other by the thrust 9 and are connected with the crank cam 11 by means of the connecting rod 10. Besides, the lever-gear 12 connects the traverse to the same cam-bolt mounted on the single-turn actuator 13, and the traverse moves in the guides 14. The device operates as follows: A group of bricks 3 installed at certain intervals enters the roller table 1 to the position specified by the electric sensor (not shown in the drawings). The actuator 3 actuates, indicating one revolution to the crank-cam P (Fig. 30). Under the action of the crank cam, the lever gear 12 of the traverse 7 rises, the brackets 5 raise all groups of bricks 3 above the roller table ffig 3, and under the action of the crank as it rotates at an angle of 180, the rod 10 converts all the levers 6 from the leftmost position to the extreme right position Sfig.Z S). At the same time, the group of bricks turns at an angle of 90 around its longitudinal axis, not deviating from its location8 and maintaining the same predetermined interval between them. Upon further movement of the cam, the crank — turning it to the next 180 — the yoke descends (Fig. 3 d) groups of bricks are laid on the roller table rollers, and the brackets 5 lowered below the upper level of the roller of the roller table return to their original left position. The rollgang 1 moves the tilting of the brick a step, others take their place. The device is ready for the next cycle. The proposed device provides the ability to perform the turning operation of groups of bricks in mass production, on the same transport mechanism-roller table, without increasing its overall dimensions. This is especially true for laying bricks on the kiln cars on the die in the manufacture of facial bricks, when mounting on the tray is unacceptable. Since the drying takes place on the tray, and the firing must be done on the plsk, the turning operation is inevitable. The proposed device ensures that this operation is carried out in a stream, at a high performance, and is easily integrated into the overall dimensions of the transmission mechanism of the roller table.
