It was filed on May 4, 1938 in NKHP for the number 16487.. Published July 31, 1940.

Machines for separating stacked flat pieces of elastic material from one another, based on the principle of bending a pack on a series of consecutive rollers, are generally known.

In the proposed flat shoe rubber sheet dispenser, this principle is used in conjunction with the principle of separation of parts. By means of rolling a bundle with moving rollers, this gives a great effect on individual packs of tangential forces, resulting in high machine productivity as in individual roll packs and sense of separation of one part from another, that with materials having, within certain limits, adhesion and adhesion, such as rubberized m of materials (insoles, heel and other parts) plays a very important role.

The invention is illustrated in a schematic drawing, FIG. 1 which depicts a common principle device; FIG. 2 - ripper using if

methods for applying glue to supplied parts; and FIG. 3 - ripper with the use of a conveyor belt for receiving individual parts arranged by a ladder for the purpose of applying glue on their edges.

As can be seen from FIG. 1, the roll distributor consists of a hopper 10 where a bundle of parts is laid, endless belts 4 6 between which the bundle is divided into separate parts, and an apron 11 for adjusting the size of the receiving opening.

The endless belt 4 comprises a series of rollers 1 arranged in a circle and freely rotating on their axes, and a tension roller 5. The axes of the rollers / are fixed on the disks 2, the axis 5 of which rotates together with the disks from the driving pulley. The belt 6 covers the rollers 7 and P and the tension drum 8 in such a way that presses the belt 6 against the rollers 1. A ratchet with two dogs of different lengths not shown in the drawing is mounted on the roller 9 in order to be able to control the speed of movement of the belt 6.

The hopper 10 is located above the tape 4 and has an open bottom (tape 4 serves as the bottom). On the front wall of the bunker is a fabric or metal apron L; With the aid of two screws 72 and a hinge / 5, this apron can move up and down along the wall of the bunker, increasing or decreasing the gap - between the tape 4 and the apron. In addition, at the hinge 75, the apron 77 can be rotated in such a way that the gap between the belt 4 and the apron 77, decreasing on one side, increases on the other.

The operation of the dispenser is as follows (Fig. 1). The rollers 7, where they touch the belt 4, begin to roll along the belt. Waves (bends) are created on the tape and on the parts adjacent to it. These waves move in the direction of movement of the axes of the rollers, and therefore the tape and the parts adjacent to it begin to move towards the apron 77, and the speed of movement of parts decreases as they are remote from tape 4 and rollers J, which shifts one part relative to another. adhesion forces between them. The adjustable gap between the apron 77 and the belt 4 determines the number of moving parts.

Details then enter the space between the ribbons and & Here, under the influence of the same waves, they continue to move further, simultaneously being bent by radius /, which increases the tangential forces that overcome the cohesive forces between the individual parts. The speed of the tape 6 is always less than the speed of the tape 4; the smaller this difference, the greater the productivity of the pulverizer; the performance also determines the size of the gap between the belt 4 and the apron 77.

Sometimes parts go forward at one of their ends, i.e. they are warped. This is eliminated by the reverse skew of the apron 77, i.e. an increase in the gap on one side and a decrease on the other. As a result, the parts emerge from the gap between the ribbons 4 and 6 in a more or less even ladder, which makes it possible to use a ripper for mechanization of the following manual operations:

1. Application of glue on one or both surfaces of parts (Fig. 2). For this purpose, a bath 75 with glue and spreading rollers 14 and 75 is attached to the spreader.

Spreading rollers have a circumferential speed greater than the speed of a ladder of moving parts. The edge of the part falls between the rollers J4 and 75; the part carried by the rollers is removed from the ladder and is coated on one or both sides.

2. Namazka glue edges of parts (Fig. 3). In this case, a belt conveyor is attached to the racker. In order to spread the flat parts along the edge of the part, it is necessary to unfold it in such a way that they are slightly shifted one relative to another, forming a ladder, and then the open part of each part is a spread edge.

The rake spreads the parts into the ladder on the conveyor belt 16, on which the parts are smeared with glue manually or mechanically with a roller (in Fig. 3, the spread is not shown).

The belt 16 is set in motion from gear 19, mounted on a racer wheel, driving gear J8 associated with conveyor drum 17.

The subject matter of the invention.

Claims (5)

1. Spreader of flat parts of rubber footwear using a series of rolling rollers arranged in series around the circumference, characterized in that the rolling rollers 7 are connected not only to rotate around their own axes, but also around a common axis 5, in order to form kinks of the parts. 2.When the razachkovyvatel under item 1 the use of an endless belt 6, located between the end of the apron 77 and the tape 4 and driven in motion at a slower speed than tape 4, in order to further disengage and advance the parts. 3. In the stacker, in accordance with claim 1, the use of the bunker 10, in which the apron is attached to the hinge, can be moved up and down in order to change the gap between it and the belt 4. 4. When using the dispenser according to iff 1, use a bath for glue and rollers 14 and 15 for applying glue to the supplied parts (Fig. 2). 5. When using the stacker in accordance with claim 1, use a conveyor belt / 6 for receiving stained and stacked parts, in order to apply glue to their edges (Fig. 3).  iO that in n “D "about. 5 th  Yu s W and n d S g g I & | in with m  about ( . g n and oh and Ph about n m her i
