Description

one

The invention relates to the manufacture of rubber or latex rubber products and is intended, in particular, for devices for removing the rubber articles from forms, for example, gloves.

A device for removing molds of grooved articles, for example gloves, is provided, which contains a mechanism for moving form holders with turned down part down forms, drive rollers for preliminary removal with plates of elastic material and a mechanism for final removal.

In the known device for removal of the product from the form provided the use of grippers of the upper part of the gloves, which leads to damage and defective products.

A distinctive feature of the proposed device is that the mechanism for the final removal is made in the form of a pair of contacting drive rollers with elastic plates, installed during the movement of the molds with the products behind the rollers for the preliminary removal and located below the level of the lower points of the molds.

Roller plates for non-invasive removal are made with a rectangular cross-section, and rollers for final removal of the product are made with a triangular cross-section.

FIG. 1 schematically shows the proposed device; in fig. 2 and 3 — rollers performing the final removal of products; in fig. 4 and 5 - rollers carrying out

preliminary removal of products.

The device includes a mechanism for moving the mold holders 1 with the downwardly dipping part down with the molds 2 with the articles 3. The guides 4 and 5, conventionally shown in FIG. 1, only at the beginning and at the end of the device, serve to move along them the frames with form holders 1. At the end of the guide 4, a limit switch 6 is installed. The mechanism for the assembly of products 3 contains

a pair of drive rollers 7, carrying out the final removal of products, and three pairs of rollers 8, carrying out preliminary removal of products. The rollers 7 are mounted along the movement of the molds 2 behind the rollers 8 for preventive removal and are located below the level of the lower points of the molds 2. Each roller is provided with a lining of resilient material made with longitudinal flat edges.

The plates 9 of the rollers 7, carrying out the final removal of products, are made with a triangular cross section, and the plates of 10 rollers 8, carrying out the preliminary removal of products, are with a triangular

but the cross section.

On the axis of each of the rollers 7 and 8 of the nasal-hay is an asterisk 11. The rollers 7 and 8 are installed in a horizontal plane and in the diagram (Fig. 1) are conventionally shown without longitudinal working protrusions. The number of pairs of rollers 7 and 8 may be different. Under the rollers 7 and 8, a chute 12 of water discharge is installed inclined to the horizon, terminating under the rollers 7 with a tank for receiving the removed articles 3 and collecting water.

Before each pair of rollers 8, a pair of nozzles 13 is installed for supplying water or air.

The mechanisms for moving the mold holders 1 and for removing the articles 3 are driven from the engine 14 through the sleeve 15, transmitting the movement to the gearbox 16, on the output shaft of which is mounted an asterisk 17 and a conical brush 18.

To transmit motion to the shaft, Icam 7 and 8 is an asterisk 17, connected by chain 19 with the help of tension rollers 20, 21, 22, 23 with asterisks 24, 25, respectively, mounted on shafts 26, 27.

Shaft 26 has four stars 28, and shaft 27 has four stars 29. Stars 28 and 29 chains 30 are associated with asterisks 11 rollers 7 and 8.

The second branch of the transmission goes from the pinion 18, which is a pair with a conical bristle 31, mounted on one axle with a bristle 32, forming a pair with a bristle 33 33, mounted on an axis with an asterisk 34.

The asterisk 34 is connected by a chain 35 with the help of tension rollers 35 with asterisks 37 mounted on common axes with rubberized rollers 38 in contact with the frame of the mold holder 1 (Fig. 5).

The rollers 38 are arranged in pairs with an interval equal to or less than the length of the frame of the form holder 37.

The guides 4 and 5 are inclined with a rise in the direction of the rollers 7.

The device works as follows.

From motor 14, through coupling 15, gearbox 16, a conical pair of gears 18 and 31, a pair of gears 32 and 33, an asterisk 34 connected by a chain 35 using tension rollers 36 with air rims 37, rotates the rollers 38 mounted on the axis common with asterisks 37.

From sprocket 17, linked chain 19, with the help of tension rollers 20, 21, 23, 24 with sprockets 24 and 25, rollers 7, carrying out the final removal of articles, and rollers 8, carrying out preliminary removal of products, receive a rotational movement from four the sprockets 28 of the shaft 26 and from the four sprockets 28 of the shaft 27 connected by chains 30 with the sprockets 11 of the rollers 7 and 8.

The PaMtKH form-holders 1 with form1M1I 2 into the device are manually fed to the directions HUie 4 and 5. The first pair of rotating rollers 38 captures the fed-in frame with the forms 2 and passes it on to the next pair throughout

the length of the inclined guides 4 and 5. The molds 2, which are turned by the dunnage part, move between the rollers 8, which are used for the preliminary removal of products, along an inclined bottom-up and pass over the rollers 7, which serve for the final removal of the products.

Before each pair of rollers 8, which serve to pre-remove the products, water is injected from the nozzles 13 onto the forms 2, wetting the outer surface of the product 3 and form 2. Injected into the product 3, water dissolves the retainer, which turns into a lubricant and contributes to uniform

I will remove products 3 from forms 2.

Each rotating pair of rollers 8 with longitudinal flat edges gradually shifts the products 3 according to the forms 2 downwards by a certain distance, down to the hanging of the articles from the forms (Figs. 2, 3). The articles 3 hanging from the forms 2 are captured by the longitudinal flat edges of the rotating pair of rollers 7 which carry out the final removal of the product (Figs. 2, 3). Plucked from the shape of the product

and are dropped into the chute 12 and the stream of collecting water is carried to the gutter tank, from where they are directed to the following manufacturing processes for the manufacture of gloves. Timely not removed from the guides 4, 5 frame

with the form carriers 1, it rests against the limit switch 6, and the device stops.

The device can also be used to pick up rubber gloves, provided that nozzles 13 will be used to blow air on products 3 on forms 2. Air blowing promotes preliminary detachment of the product from the mold and helps to uniformly remove (shift) the product.

with the form.
