SU1574525A1 - Arrangement for stowing elastic material to a stack - Google Patents

Abstract

The invention relates to the processing of an elastic material, namely to the packaging units of elastic materials. The purpose of the invention is to improve the quality of styling. A device for stacking an elastic material in a stack contains feed rollers 1, a platform 6 for the foot, reciprocating, and support-rolling rollers 5, mounted on a movable rack 2, freely installed in vertical guides. The support-rolling rollers 5 are made swinging, they are mounted on the movable rack 2 with the possibility of rotation relative to the place of attachment and fixing them in the extreme positions. To transfer the support rollers 5 from one extreme position to another, platform 6 has stops 7 installed. 1 Il.

Description

The invention relates to the processing of elastic materials, namely to the nodes of the elastic material.

The purpose of the invention is to improve the quality of styling.

The drawing shows the device, side view.

The device for stacking the elastic material in the stack contains feed rollers 1, a movable vertical column 2, with which the spring-loaded spring 3 is pivotally connected to the shift lever 4 carrying the supporting rollers 5, and the platform 6 with lateral stops 7. Support rollers 5 are installed with the possibility joint rotation with the shift lever 4 and alternately interacting with the material 8 and the side stops 7.

The device works as follows.

The elastic tape material 8 is fed by the feed rollers 1 to the stacking area and passes between the supporting rolls 5, which are under the action of the spring 3 in one of the extreme positions

When the platform 6 is moving, one of the support-rolling rollers 5 presses the stacked material 8 against the layers of the foot, lays it down, rolls it out and at the same time compacts the foot. In the extreme position of the platform 6, one of the stops 7 presses on the support-rolling rollers 5 and due to the force created by the movement of the platform 6, transferring them to another extreme position, after the platform 6 changes its direction of movement and laying the material 8 in the foot goes on.

As the height of the foot increases, the mobile stand 2 with the support-rolling 5 rollers rises. When the foot reaches the required height, the material 8 is cut off, the foot is removed, after which the device is ready for operation

In the proposed device, the process of forming the edge of the foot is carried out directly by the support-rolling rollers without the use of bulky additional nodes.

In the extreme positions of the platform 6, the stops 7 are in contact with the raised roller 5. Since the rollers 5 are mounted on the shift lever 4, the moment of rollers 5 turning over occurs after the passage of the middle lever 4

position (when both rollers are in contact with the foot). Up to this point, the roller 5 raised above the foot overlaps the stop 7 of the platform 6. Since the supply of material 8 does not stop, a small loop is formed in the area between the rollers 5, which roller 5 gradually kneads without pulling off the material. A tight and even edge of the foot is formed by uniformly turning the support-rolling rollers 5 relative to the axis of the shift lever 4. This is achieved by balancing the active forces that turn the resistance forces. In the first phase of rotation (until the intersection of the axis of the spring with the axis of rotation of the switching roller), the active force is the force acting on the side of the cart stop, and the resistance force is the force of the spring tension. In the second phase, after the lever passes the unstable equilibrium line, the active force is the regenerative force of the springs, and the resistance force is the weight of the rollers with guides that must be raised to rotate the support-rolling rollers to a new stable position. The platform reverser is made after the lever passes the unstable equilibrium.

Such a structure allows high-quality elastic material to be placed in the foot. In addition, the design of the device is very simple. Using only one drive for the platform greatly simplifies the setup of the stacking device.
