The invention relates to the construction, can be used in the manufacture of products from plastic materials, such as concrete, mainly in the production line, and is an improvement of the device according to the author. St. No. 1172722.

The purpose of the invention is to increase productivity and reduce energy costs.

Figure 1 shows an installation for the manufacture of products from plastic materials, a general view; figure 2 - the feed mechanism of the pallets; fig.Z - node I in figure 1; figure 4 - node II in figure 2.

The installation for the manufacture of articles made of plastic materials contains a device 1 for forming with a vibrating plate a device 2 for metering plastic materials and loading pallets, a frame 3 with guides 4, a rigidly fixed accumulator 5 pallets with a fixed folding stop 6, a mechanism 7 for cleaning pallets, a device 8 for separating the products from the pallet 9 by guide posts 10.

In the guides 4, there is a pallet feeding mechanism, made in the form of a movable frame consisting of two sections: a section 11 of a stack of pallets and a section 12 of a stack of products. Sections 11 and 12 are arranged coaxially with the possibility of horizontal displacement.

Section 11 is provided with folding stops 13, which are installed in increments of a multiple of the width of the pallet 9 and their distance of operation. Section 12 is provided with a roller bearing 14 and a storage device 15, rigidly fixed at the level of the pallets 9. Section 11 and 12, respectively, have a separate drive 16 and 17 of reciprocating motion.

Roller bearing 14 is made in the form of twin roller clips 18-20. The centers of the rollers 21 in each of the clips 18-20 are displaced by the amount of (0.6-0.8) H, where H is the height of the pallet 9. The displacement creates a smooth movement of the pallet 9 without jamming and its uniform contact at no less than three points .-when moving around the clips 18-20.

The drive 15 is equipped with a flash remover 22. Device22

22 is embodied in the form of stops 23, which are mounted with the possibility of lateral movement along a guide (not shown) fixed on the bottom surface of the accumulator 15 in such a way that the stops 23 protrude above its working surface. On the accumulator 15 there is a rigidly secured t ha 24, on which a copier 25 is installed, the accumulator 5 of pallets 9 is made of box section. The side walls 26 of the accumulator 5 are rigidly fixed on the bed 3. The side rear wall 26 is fixed to a fixed rear wall 27, which can be made with stiffeners.

The front wall is made in the form of levers 28 connected by a rigid web 29. The lever 28 is hinged at one end on the side walls. 26, and on the other there is mounted a roller 30 in contact with the cam 25 of section 12 of accumulator 15,

The trajectory of movement of the roller 30 on the copier 25 is chosen in such a way that the angle in the plane of contact of the roller 30 and the copier 25 is less than the friction angle, which eliminates jamming; and the curvature of the working surface of the copier 25 is selected depending on the height of the pallet 9.

A rigid web 29 and a rear wall 27 are mounted relative to the guides 4 and the roller cage 20 with a gap that exceeds the thickness of the pallet 9.

The fixed folding stop 6, which keeps the pallet 9 from moving towards the accumulator 5, is rigidly fixed on the base 3 and is designed in such a way that it clicks as the pallet 9 moves towards the accumulator 5.

The mechanism 7 for cleaning the pallets is made, for example, in the form of a rotating brush, the activation of the drive of which is connected automatically with the movement of the accumulator 15,

Between the device 8 for separating the products from the pallet 9 and the accumulator 15, the reception area of the hardened products equipped with guide pillars 10 allowing the pallet 9 with the products to be oriented relative to its feed axis is placed.

The installation is equipped with an electro-automatic control system 31, which is designed as av312 sensors.

the thematic actuation installed on the bed 3 and allowing the drive of the mechanism 7 for cleaning the pallets and the drives 16 and 17 of sections 11 and 12 to be controlled;

A hardening zone of the molded products (not shown) is provided to maintain the process cycle next to the installation.

The operation of the plant for the manufacture of articles of plastic materials can be carried out in three modes: molding products and dismantling solidified products; the removal of hardened products and the supply of pallets 9 in the drive 5; Forming when feeding pallets 9 from accumulator 5.

When molding products and demoulding solidified products, the actuators 16 and 17 of the reciprocating engine set sections 11 and 12 to their initial position, in which the accumulator 15 moves together with the roller bearing 14 to the extreme right position, freeing the receiving area of the solidified products of the pallet 9 with hardened between the device 8 and the accumulator 15. Section I1 moves to the extreme right

the At the same time, on the vibroplate of the device 1.dl for molding there is a pallet 9 with molded articles.

With the forward movement of section I to the extreme left position by folding lugs 13, the pallet 9 is moved to the molding zone of the device 1, and the previous pallet 9 with freshly molded products is moved to the hardening zone. When forming, the system 3 electro-automatic control turns off the drive 16 and turns on the drive 17 to work.

When the section 12 is moved to the extreme left position, the accumulator 15. moves the pallet 9 with hardened products to the device 8 for separating the products from the pallet, moving the products to the accumulator 15, and the pallet 9, moving on the roller support 14, passes under the cleaning mechanism 7 pallets to the hopper 5. The products moving over the surface of the hopper 15 between the stops 23 of the device 22 are freed from dips and chips.

When the drive 16 is turned on, section 11 automatically turns on the drive of the mechanism 7, cleaning under

dong 9 from the remnants of the molding material. When moving section 11 to its original position, the copier 25 through the roller 30 of the lever 28 raises the jumper 29. When the section 11 moves to the left position of the ha 24, moving the copier 25 with the roller 30, lowers the jumper 29.

When molding, in the accumulator 5, the pallets of the pallets 9, the lower surface of the installed pallet, is bbmie the upper surface of the subsequent pallet, which, when moved in, the accumulator 5 raises the upper pallet and is installed under it. By reversing, section 12 moves the hardened products together with the hopper 15 to feed the next pallet 9 with hardened. products that, entering the drive 15, promote the precursors and group them into a transport package. The cycle of stripping and moving the pallets 9 into the hopper 5 is repeated.

At the end of the molding process, section 12 occupies the initial position. Section 11 moves to the leftmost position, with front flap 13 moving pallet 9 with freshly molded products to the hardening zone, and the last flap stop pulling the bottom pallet 9 out of the stack of pallets 9 located in the accumulator 5. Intermediate folding flaps 13 move the pallets 9 along guide 4 one step. Section 12 returns to its original position.

The molding cycle is repeated and at the same time 2-3 stripping cycles of hardened products occur.

When the plant operates as a demolisher, for example, with the molding device 1 turned off, the process of stripping and moving the hardened products to the drive 1.5 proceeds in the same way as when forming and stripping at the same time, but the electro-automatic control system 31 turns on the actuator 16 of section 11

When forming products without demolding, pallets 9 are delivered from accumulator 5 in the same way as during molding and demoulding at the same time, but the electro-automatic control system 31 disables the drive 17 for moving section 12 and the drive for the pallet cleaning mechanism 7.
