SU168154A1 - DEVICE FOR CHANGE OF PITS, FOR EXAMPLE, ON TAPE MACHINES - Google Patents

Description

There are known devices for changing basins on belt machines, comprising an endless conveyor supplying empty basins to the paver; To remove the pelvic from the band-laying machine, a device with a mechanism for grasping the cans and driven by an electric motor, activated by a maschine counter signal, is mounted on its lower base.

The proposed device differs from the known simpler design.

This is achieved by the fact that the device for withdrawing the pelvis is made in the form of a carriage equipped with horizontal rails which are in engagement with the gear of the drive. The carriage is driven (reciprocating along guides mounted on the bottom base of the paver, equipped with a latch retracting under the action of an electromagnet, which serves to skip the next empty pelvis that enters the paver. Switches are also attached to the rails. (reversing the direction of rotation) of the electric motor, as well as stopping it and turning off the lock electromagnet.

on the spring-loaded levers, and in the drive of the device used gearbox and electromagnetic brake.

FIG. 1 shows a device for changing the pelvis, side view in section; in fig. 2 - the same plan; in fig. 3 shows the kinematic scheme of the proposed device. In series with the infinite falling empty basins / conveyor 2 is mounted

The paver, on the lower base 3 of which is located a pillow 4, driven by a screw 5, mounted on a shaft 6 connected by a chain transmission 7 (Fig. 3) with a feed conveyor.

On the bottom base of the paver, a device is installed for withdrawing the pelvis, made in the form of a carriage 8, moving 1 along the guides 9 and 10. The reciprocating movement of the carriage is carried out using gear racks 1} and} 2, which engage with gear 13 and 14, the shaft of which is driven into rotation by a reversible electric motor 15 via a gearbox 16 and an electric brake 17.

A carriage of pesetas on itself is a mechanism for capturing the pelvis, which includes rollers 18 interacting with the pelvis and shifted relative to each other vertically, which are mounted on brackets 21 on both sides of the carriage equipped with coil springs.

On the bottom base of the paver, a controlled electromagnet is installed. Volume 22 is a spring-loaded latch 23, limiting the flow of the empty next pelvis to the sub-pad. The reversible motor and the latch are controlled by limit switches located at both ends of the carriage guides.

After placing a pelvis of a certain length of tape rotating on a sub-nick, the device counter (not shown in the drawing) gives an electrical signal to turn on the carriage motor and set the lock. Moving, the carriage tilts the filled pelvis with the rollers of the gripping device, removes it from the sub-pedal and feeds it to the roller conveyor 24. At the same time, the next empty pelvis is fed to the sub-pedal. Interacting with the limit switch, the carriage reverses the direction of rotation of the electric motor and includes a retainer. When the carriage returns to the rightmost position, the limit switch 25: turns off the electric motor. At this point, the operation cycle of the device is quenched.

Subject invention

Claims (3)

1. A device for changing the pelvis, for example, on tape machines, consisting of an endless conveyor that supplies empty basins to the paver, on the basis of which a device is installed to remove the pelvis from under the paver with a catch mechanism of the pelvis and a drive from an electric motor that is activated machine counter, characterized in that, in order to simplify the construction, the device for removing the pelvis from under the paver is made in the form of a carriage equipped with horizontal rails kinematically connected with the pole ph drive and driven in a reciprocating motion mounted along the bottom base of the sheet paver with retractable 5, under the action of an electromagnet, a spring-loaded clamp, for passing a regular empty pelvis from the conveyor belt to the paver, and the final electrical contacts; when the carriage interacts with one of them, the electric motor is switched and the carriage is told to reverse motion before it encounters another contact, which provides for switching off the electric motor, stopping the carriage and switching off the electromagnet to return the spring-loaded lock to the initial lift. 2. The device according to claim 1, characterized in that the mechanism for grasping the cans is made in the form of rollers mounted with brackets on both sides of the carriage on spring-loaded levers. 3. The device according to claim 1, characterized in that the drive uses a gearbox and an electromagnetic brake. -P / 2 5 P IS Fig 3
