Description

(54) DEVICE FOR LAYING EXTRUDED PANELINE PALLETS

one

The invention relates to the production of building materials, namely, equipment for the extrusion molding of asbestos-cement, ceramic and other products.

A device for laying the molded products on pallets is known, including a receiving roller table and a cutting device 1.

A disadvantage of the known device is a large plastic deformation of the panels on the roller tables under the action of its own weight, which does not allow the formation of thin-walled panels of large thickness with a small number of internal partitions, which, after hardening of the panels, only increase their weight and reduce the thermal performance.

Closest to the present invention is a device for laying extruded panels on pallets containing its receiving conveyor and a vacuum chamber located above its working branch, the bottom of which is made in the form of a perforated tape and an anvil 2 associated with it.

However, the device cannot be used in extrusion plants that form thin-walled panels of large thickness from asbestos-cement, gypsum-fiber, ceramic and similar plastic materials, since in this case it is necessary to continuously support the product throughout its upper plane from the extruder die to the special pallet, and it is impossible to tear the product off the conveyor, and only support it, otherwise the product will also be deformed.

The purpose of the invention is to improve the quality of stacking panels.

The goal is achieved by the fact that the device for laying extruded panels on pallets, containing a receiving conveyor and a vacuum chamber located above its working branch, the bottom of which is 15 shaped like a perforated tape and a stop connected to it, is equipped with movable carts relative to a receiving conveyor, and, an additional vacuum chamber, with the main and additional vacuum measures placed on the carts, and their perforated tapes are mounted so that they can move The carriage is positioned with a slope in the direction of the extruder, and the carriage adjacent to the extruder is equipped with a cutter. FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. 1. A device for laying extruded panels on pallets consists of receiving 1 and accelerating conveyors 2, made in the form of roller tables installed with a slope towards the extruder 3, the main 4 and an additional 5 vacuum chambers. Vacuum chambers 4 and 5 are located on trolleys 6 and 7 supported on conveyors 1 and 2. Vacuum chambers 4 and 5 have bottoms made in the form of belts 8 and 9, respectively, pulled on drums and having perforated sections 10 and 11 with stops 12 and 13. Vacuum chambers 4 and 5 are equipped with exhaust fans 14 and 15. On the trolley 6, a cutter 16 is mounted. At the end of the accelerating conveyor 2 there is a pallet 17 with brackets 18 for supporting panel 19 and a lock 20. The device works in the following way . Trolleys 6 and 7 as a result of tilting the frame of conveyors 1 and 2 are located near the extruder 3. The extruded panel 19, acting on the stop 13, turns on the fan 15 of the vacuum chamber 4 and begins to move the belt bottom 8 so that its first section 10 is perforated contact with the panel and as a result of the vacuum created in the vacuum chamber 4 by the fan 15, the panel 19 is attracted to it and part of its weight is perceived by the trolley 6. When the panel 19 reaches the end of the vacuum chamber 4, which corresponds to the set length of the panel, the cutting mustache 16, and the belt bottom 8 stops and both carts 6 and 7 move synchronously with the panel 19. After the end of the cutting, the stopper (not shown) of the belt bottom 8 is turned off and the panel 19 is fed through the accelerating conveyor 2 under the vacuum chamber 5, while I act on the stop 12, turns on the fan 14 and moves the belt bottom 9 so that its perforated section 11 comes into contact with the panel 19 and as a result the panel 19 formed under the vacuum vacuum chamber 5 is sucked to the bottom 11 and transfers part of its weight to trolley 7, which is conveyed pv 2 together with the panel 19 is moved to the pallet 17. At this time otkatyvaets carriage 6 in its original position for receiving the next panel, with the bottom belt vacuum chamber 4 is transferred to the closed position, i.e. the perforated portion 10 is in the upper position. When the carriage 7 is fixed above the tray 17, the lock 20 is closed and the console 18, entering the voids of the panel 19, perceives the weight of its upper wall. Then the fan 14 is turned off and the carriage 7 is rolled back to its original position, with the belt bottom 9 of the vacuum chamber 5 being brought to the closed position. A pallet 17 with panel 19 is sent to the pre-hardening chamber, and a free one is installed in its place. The cycle is repeated without stopping the extrusion process. The use of the proposed device allows reducing plastic deformations of the panels on the roller tables and the pallet under the action of their weight, which will increase the accuracy of the geometric dimensions, making it easier to install them on construction sites, form thicker panels required for the northern regions, form panels with thinner walls and fewer internal partitions, which will reduce their consumption of materials and weight and improve thermal performance. Apparatus of the Invention A device for laying extruded panels on pallets, comprising a receiving conveyor and a vacuum chamber located above its working branch, the bottom of which is made in the form of a perforated tape and an abutment associated with it, characterized in that in order to improve the quality of laying of panels, the device equipped with carriages mounted for movement relative to the receiving conveyor, and an additional vacuum chamber, with the main and additional vacuum chambers placed on the carts and their perforated The belts are mounted for movement relative to the carts, while the receiving conveyor is inclined towards the extruder, and the carriage adjacent to the extruder is equipped with a cutting device., Sources of information taken into account during the examination 1.
