Description

I

The invention relates to installations for the manufacture of ceramic products, mainly drainage pipes, and may find application in the construction materials industry.

In the main invention auth.St. No. 737218 described production line for the production of ceramic pipes. This production line consists of a section for forming and drying pipes, containing a molding press, cutting machine, rotary selector, stepping frame feeder for loading pipes, machine frame stacker with pipes to the drying trolley, drying car feeders, dried and frame-raiser; section of pipe laying on kiln cars containing an automatic unloader of pipes from drying cars, reloader, cross-line conveyor, automatic pipe killer, on kiln cars, kiln feeders an outlet, and a pipe unloading area from the kiln carts, containing an automatic pipe unloader from the kiln car

cross conveyor and reloader 1.

Its disadvantage is the low reliability and performance of the pipe unloading section from the drying cars and loading them onto the firing line and, in particular, the pipe reloader to the cross-line conveyor. This is due to the fact that the reloader is equipped with individual grippers for each pipe, and since the pipes after drying are located on the drying frames with a significant deviation from the nominal position, then removing them from the grab N01 causes considerable difficulties, requires manual dressing of the pipes, and this leads to a violation of the automatic , cycle, reduced production, breakdowns and complicated equipment maintenance.

The purpose of this invention is to improve the performance of reliability.

This is achieved by the fact that the reloader is made in the form of a carriage that carries the interlocked bodies of plunger hydraulic cylinders with a hydraulic distributor, with a pusher support fixed on it, with the carriage located

The hell of the fixed guides of the auto-loader is perpendicular to them, and the guides in the zone of the loader are made with a clone.

In addition, the pipe reloader is equipped with a shut-off device, designed as a moving frame with a vertical displacement drive, a frame position indicator and a control unit connected to the carriage valve.

W FIG. 1 shows a section for unloading a thrc with a drying trolley and laying them on a firing, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG.

The section for unloading pipes from a zonilny trolley and laying them on the firing vans consists of an automatic discharger of 1 pipes from the drying trolleys, an overload truck 2, a transverse horizontal conveyor 3, an automatic saddle 4 pipes to the firing trolleys.

The automatic unloader 1 of pipes with drying trolleys consists of a reducing agent 5, a stripper 6 frames with pipes, a pusher 7 with hooks and fixed guides 8.

Reloader of 2 pipes with drying frames on the cross-line conveyor. 3 comprises a carriage 9 consisting of plunger hydraulic cylinders 10 with an anvil 11 guided by a casing 10, guides 12, a distributor 13 with a control electromagnet, a cutter 14 consisting of a moving frame 15 with a vertical displacement actuator 16, a position indicator 17 of the frame and control units 18. Cross-line conveyor 3 consists of a conveyor 19, the actuator 20 and the movable stop 21.

The pipe unloading section from the drying car and laying them on the firing production line works as follows.

Loaded drying trolleys 22 with dried pipes are fed into the descender 5 of the automatic unloader 1, the puller 6 reduces the group of frames with the pipes with the attenuator 5 and nepeHooiT them onto the fixed guides 8. The pusher 7 with hooks advances the frames with the pipes along the fixed guides 8 to the post collide. A shutoff device 14 is located in front of the collision post over the pipe, and the guides 8 in the area of its operation have a slope 23 through which the frame with the pipes deflects forward, forming a gap followed by a series of pipes for the entrance of the shutter. The frame 15 of the pruner 14 is lowered between the rows of pipes, trimming them, the position indicator 17 gives a signal to the control unit 18, and the latter gives a permit signal to the solenoid valve 13 solenoid valve 13 for pushing the pipes. The carriage 9 makes a working stroke and with the help of a one-way stop 11 pushes a row of pipes onto a cross-line conveyor 3 consisting of a drive 24 and a non-drive 25 sections. The tubes pass the drive section and are pushed onto the non-drive. The discharge cycle continues until it is completely filled, the drive section of the row conveyor. As soon as the extreme pipe reaches the movable stop 21, the drive 20 of the horizontal conveyor is switched on and the control electromagnet (not shown in the figures) of the distributor 13 of the hydraulic cylinders 10 of the carriage 9 is prohibited, and the pushing of the pipes stops.

The automatic saddler 4 with its grippers 26 removes the typed line and transfers it to the burning car 27.

After removing the line in the presence of an authorization signal from the control unit 18, the drive 20 of the line conveyor is turned on and the prohibition on the operation of the loader is lifted.

The rowset cycle repeats.

In the case of a strong shift of the pipes on the frames beyond the allowable limit, the fixed guide rails 8 on the equipment 23 do not form a gap sufficient for the entry of the shutoff device. In this case, the frame 15 of the shutter 14 is not included in the gap between the pipes, the position indicator 17 of the frame does not give a signal to the control unit 18, the time relay is activated (not shown in the figures) and, simultaneously with the prohibition of the overloader's operation, a signal is sent to the control unit (in the figures not shown) on the malfunction of the unloading.
