Abstract

The invention relates to the production of building materials, namely, devices for transferring freshly molded building products from a molding machine to a curing conveyor. The invention makes it possible to reduce scrap when transferring products by providing simultaneous support of two product surfaces due to the fact that the transfer carriage is provided with a removable lodgement for laying ducts made with rollers and trunnions and two support surfaces for the product at right angles to one the other, and the grippers are in contact with the cradle axles. 6 Il.

Description

The invention relates to the production of building materials, namely, devices for transferring freshly molded building products from a molding machine to a curing conveyor.

The purpose of the invention is to reduce rejects when re-positioning products by ensuring the two surfaces of the product are simultaneously supported.

Figure 1 shows the device, a general view; figure 2 is a view of And figure 1; FIG. 3 shows a lodgement with a square-shaped box; Fig. 4 is the same, with a rectangular non-square box; Fig. 5 shows the beginning of the lowering of the lodgement with the box of non-square section; FIG. 6 shows the end of laying of the lodgement with the box of non-square section.

The device for transferring building products, predominantly freshly formed asbestos-cement rectangular ducts, comprises an overpass 1 with a driving trolley 2 on which a lifting and lowering mechanism 3 is mounted with a gripping member having a gripping 4 with a fixing supporting surface and a gripping 5 with a straight supporting surface. The grippers are fixed on the lifting-lowering mechanism pivotally and connected to each other by means of the gear sectors 6 and 7, which have a turning drive (not shown).

Under the overpass 1, there is a transfer carriage 8 for removing the newly formed boxes 9 from the mandrel 10 of the molding machine 11 and transferring these boxes to the conveyor 12 solid 4

neither The transfer trolley has a lifting device 13 and two rows of supports 14 and 15, adjustable horizontally (supports 14) and vertically (supports 15) and in contact with rollers 16 of a removable bed 17, designed for laying ducts 9. For adjusting supports 14 and 15, any known means may be used (for example, grooves, gaskets, and the like). The cradle is made with two bearing surfaces 18 and 19 for the duct located at right angles to each other, and with pins 20 in contact with grippers 4 and 5. Limit switches 21 and 22 are installed on racking 1, limiting the stroke of the driving carriage 2, and the curing conveyor 12 is provided with stops 23 for moving the cradle 17. The movement drives of the carriages 2 and 8 are not shown in the drawing.

The device works as follows.

The bed 17, mounted on the hardening conveyor 12, is fed by the stop 23 under the driving carriage 2, which is in the initial position (in the figure 1 to the right). After the cradle 17 stops under the driving carriage 2, the pick-up mechanism is lowered by the lifting-lowering mechanism 3, with the aid of the toothed sectors 6 and 7, the grippers 4 and 5 are rotated and their supporting surfaces are installed under the trunnion hinges 20. Then the lifting-lowering mechanism 3, a cradle 17 rises, after which the drive carriage 2, together with the cradle, begins to move along ramp 1 to the left. On command from the limit switch 21, the drive trolley stops above the transfer trolley 8.

The lifting and lowering mechanism 3 of the lodgement 17 is laid on the transfer carriage 8, while the rollers 16 of the lodgement are supported on supports 14 and 15, and the supporting surfaces 18 and 19 of the lodgment are parallel to the respective box surfaces located on the mandrel 10 of the molding machine 1 1. The grippers 4 and 5 with the help of the toothed sectors 6 and 7 return to their original position, freeing the pins 20 of the lodgement.

machine 11 and stops under the formed box 9. The lifting device 13 lifts the lodgement 17 until it touches the box 9 and pulls away from the molding machine, removing the newly formed box from the mandrel 10 of the molding machine 11. The lifting device 13 lowers the lodgement 17 with the box 9 to the transfer cart 8 which returns to its original position (under the driving carriage 2). Next, the grippers 4 and 5 are rotated and their support surfaces are installed under the pins 20 of the lodgement 17. The lifting and lowering mechanism is activated, raising the lodgement 17 with the duct 9, and the drive trolley 2 moves them to the right.

On command from the limit switch 22, the drive trolley stops above the hardening conveyor 12 and the lifting and lowering mechanism 3 places the cradle 17 with the duct 9 in its former place on the hardening conveyor. The grippers 4 and 5 are rotated to their original position, freeing the axle 20 of the cradle. The bed with the box is moved by the stop 23 on the curing conveyor, and the next bed is fed under the drive carriage 2. Then the cycle is repeated. This is how the device works with square boxes, which corresponds to the diagram in FIG.

To reposition the boxes of a square non-square cross section (Fig. 4), it is necessary to adjust the position of the bed 17 on the transfer carriage 8 so that the supporting surfaces 18 and 19 are parallel to the sides of the box 9 on the mandrel 10 of the molding machine 11, and the points D and E (vertices box and lodgement) would be located on the same vertical. To do this, it is necessary to adjust the supports 14 and 15, as well as the position of the limit switch 21, so that one bed roller moves horizontally by B, and the other vertically by F. The size C remains unchanged. The need for such adjustment of the position of the lodgement is caused by the fact that regardless of the type of cross section of the formed box, the position of its center of gravity on the mandrel of the molding machine does not change.

The horizontal position of one of the diagonal lines of the cross section of the duct also remains variable (Figs. 3 and 4).
