(54) DEVICE FOR SUBMITTED STRIPS

MASKED

one .

The invention relates to light industry and can be used in devices for. feed multilayer decking to cutting units.

A device for feeding a multi-layer flooring is known, which contains a conveyor belt for supplying the flooring and a gripping mechanism. A desolate device of the known device is a loss of productivity due to the reciprocating movement of the gripping mechanism.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that the gripping mechanism has upper and lower guides with adjustment means installed on the sides of the conveyor, two shoulders levers fixed on the edge of the conveyor belt, carrying rollers in one end in contact with the lower guide and spring-loaded clamps movably mounted on the second ends of the two shoulders and carrying rollers in contact with the upper guide.

FIG. 1 shows a kinematic diagram of the device; in fig. 2 - the capture mechanism; in fig. 3 is an interaction diagram with an upper guide.

Multilayer feeder

5 of the flooring comprises a conveyor for positioning and supplying the flooring 1, consisting of a lead 2 and a slave 3 drums on which the belt 4 is located. Two shoulders are attached to both edges of the conveyor belt

Q are levers consisting of a bracket 5 with a clamp 7 movably mounted on the axis 6 with a spring 8 and a roller 9, and a bracket 10 with a roller 11. The rollers 11 move along guides 12 located downstream on the side of the conveyor. Above the conveyor belt, on its both sides, on adjustable racks 13, upper guides 14 are arranged, which consist of three sections. Sections I and 1P are curvilinear and serve to raise or lower the clamp, section P is straight and serves to hold the clamp in the closed position.

The device works as follows.

Flooring 1, folded in a “book or with

Claims (1)

The rolls are initially passed under the clamps 7 and placed on the conveyor belt 4. After the floor has been pressed, the conveyor drive is activated by the clamps and the belt begins to move, moving the flooring with the clamps. As the belt moves, the clamps 7 by the rollers 9 contact the curved section I of the upper guide 14, while the rollers 11 begin to roll along the lower guide 12. Rolling along section I of the upper guide 14, roller 9 overcomes the resistance of the spring 8, lowers the clamp 7 fixing the flooring on the tape. After the passage of section II of the upper guide 14, roller 9 enters section III, where the clamping is raised, the flooring is released and the rollers II come off the lower guide 12. Since the clamps are located along the entire length of the tape at a certain distance from each other, the process , clamping and releasing the flooring occurs continuously and simultaneously as the tape advances and 15. involvement of all new clamps in the working cycle. Claims of the invention A device for feeding a multilayer flooring comprising a conveyor with a belt for feeding the flooring and a gripping mechanism. characterized in that, in order to increase productivity, a gripping mechanism and has upper and lower guides with adjustments installed on the sides of the conveyor, two shoulders levers reinforced along the edge of the conveyor belt, carrying rollers in one end and spring-loaded clamps movably mounted on the second ends of the double-arm levers and carrying rollers in contact with the upper guide.
