SU142756A1 - Device for removing models and turning out nairite gloves during their manufacture - Google Patents

Description

Devices are known for removing dipped articles from small-sized models, however, they are not suitable for removing large-sized rubber products (nairets) and must be removed manually. Known attempts to mechanize this time-consuming process; This is how to remove nail gloves from porcelain models with a directional water jet. But this process makes it difficult to wash the products, as it requires an additional operation - reversing. When removing items with reversing, mutual friction of the rubber planes appears, leading to rupture of the items.

The proposed device for the removal of models and the inversion of naite gloves during their manufacture differs from those known in that the lower ends of the lever grippers are mounted to W-shaped spring-loaded brackets, on which pivot spring-loaded tongues are installed, interacting with rollers mounted on the ends of vertical tons of g. A constructive solution allows the edges of the gloves to be pinched before lifting the panel to the top position.

FIG. 1 is a schematic diagram of the proposed device; in fig. 2 - diagram of the flow of water when removing the product from the model; in fig. 3 is a schematic diagram of an average removable device; pas figs. 4 -: A-A section in FIG. 3, a section along BB in FIG. four.

The principle of operation of the machine is as follows.

The cassette 1 (fig. 1) with the products moving along the conveyor stops at a given place and switches the electromagnetic valve 1EM on two vertical hydraulic cylinders 2 by means of the end switch 1BK, carrying the outermost 4 and the middle 5 removable devices (in the figure conditionally shown), starts to go down. In the lower extreme position, the 2VK limit switch is activated, which turns on the electromagnetic spool 2EM

NO 142756-2 horizontal hydraulic cylinder 6 and the electromagnetic valve ZEM, which supplies water to the product (Fig. 2).

The stem of the horizontal hydraulic cylinder extends and transmits the movement of the wedge m / and 2 (Fig. 3 and 4) of the middle removable device. The first wedge 1 to work with an internal profile. They press through the rollers 3 on the gi 4, carrying the movable wedge 5, spring-loaded springs 6. The wedge is lowered, the arms 7, spring-loaded springs 8, are directed down towards models.

When the rollers 9 fit into the models, the wedges 2 come into operation, which by means of the rollers 10 press the coupled mounts P, spring-loaded springs 12. The pipes 1, in the lower part, carry the rollers 13, which are lowered downwards. At the same time, the W-shaped brackets M, spring-loaded with springs 15, bearing on themselves folding flaps 16, spring-loaded springs 17, rotate with the axles 18, touching with folding flaps of the rollers 13.

Turning up to the stop 19, the pin 20 of the W-shaped bracket 14 stops turning under the action of the spring 15, and the roller 13 drops down a few more.

Spring-loaded flap 16 under the action of the spring 17 is rotated relative to the W-shaped bracket 14 and its intake end with some force (because the spring 17 is slightly weaker than the spring 15) abuts the model.

At the end of the stroke; and the rod of the horizontal hydraulic cylinder 6 (see Fig. 1), the CSC operates, which turns off the 1EM and the panel 3 moves slowly upwards and when it passes the distance required to pinch the edge of the product, 4KW goes off and 2EM turns off the rod of the horizontal hydraulic cylinder 3 is drawn in and the wedge 2 comes into operation (see Figs. 3 and 4), which release the coupled spring-loaded thrust //, and the roller 13 rushes upward, rolling on the outer surface of the flap tongue 16, and clamps the tail .mku products while simultaneously turning the W-image Ny bracket 14 to the upper stop 21.

Wedges 1 (see Figs. 3 and 4) come into operation with an internal profile that move the spring-loaded wedges 5 and the last tap of the levers of 7 removable devices from the models to the stops 22.

After that, the spindle is hydraulically switched to a faster stroke. Removable devices are pulled by the edges of the product.

On the latter, pockets are formed that are filled with water. The water in the pocket, squeezing the product, presses its carrying part to the model and squeezes the turned part. Thus, water is created on the interlayer, which eliminates friction of the rubber surfaces.

Not income to the extreme upper position of the panel 25 (see Figs. 3 and 4), the 5VK limit switch is triggered, which gives a command to the ZEM solenoid valve, stopping the supply of water, and a command to move the cartridge with the models. At the same time, the spindle again hydraulically switches to slow (to avoid impact). In the extreme upper position of the panel, the rods 23 (7 in Fig. 1), rigidly connected to the spring loaded weights (see Figs. 3 and 4), abut against the stops 8 (see Fig. 1). In this case, the rollers 13 (see Figs. 3 and 4) descend somewhat downward, releasing the W-shaped brackets 14, which rotate around their axes 18 to the stops 24. The spring-loaded folding flaps 16 will open somewhat, touching the outer surfaces of the rollers 13 and products fall down.

Further, the operation cycle of the device is repeated in the above described way:

Upon removal from models of glue-up glue (products that do not require washing, it is possible to replace the water supply with the supply of talc (glue medical gloves and other products).

The proposed device (semiautomatic) is highly productive and can be used in in-line and automatic lines x -when mass and mass production of rubber products (Nairi), requiring removal with reverse.

Subject invention

A device for removing models and turning out nitrite gloves in the process of their manufacture, made in the form of a lifting and lowering panel, on which power heads are fitted, equipped with fittings for supplying water to gloves and lever hooks, in order to pinch the edges of the gloves Before lifting the panel to the upper position, on the lower ends of the lever arms, Iil-shaped spring-loaded crown brackets were mounted, on which swivel spring-loaded tabs interacting with the rollers were mounted, fixed data on the ends of vertical tons
