SU1437399A1 - Apparatus for moving semifinished leather product between processing machines - Google Patents

Abstract

The invention relates to light industry and improves the reliability of the transition of leather from one string conveyor to another. The device has means for transmitting leathers containing a shaft 3 with asterisks 4 fixed on it. The asterisks have rounded protrusions and recesses along their contour. In this case, there are blades on the sides of the protrusions on the points of the stars. Rings 5 divide the sprockets on the shaft 3. The guide shaft 3 is located above the CTpyHaNM 6 conveyors and the smooth shaft 7 is below the strings. Linear speed of the projections of the sprockets exceeds the speed of movement, the strings 1.5-2 times. 1 hp ff, 4 ill. (

The invention relates to the leather industry and can be used in the aggregates of coating dye and creating production lines for finishing operations on chrome, leather,

The purpose of the invention is povopenie reliability when rolling skin from one string conveyor to another.

FIG. 1 shows a device, side view; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. 1; in fig. 4 is a section BB in FIG. 3

The device for moving the leather semi-finished product consists of string conveyors 1 and 2, a guide shaft 3 with sprockets 4 mounted on it with protrusions and depressions and paddles located between them, and dividing rings 5. The shaft 3 between the sprockets is mounted above the strings 6 conveyor so that the separation rings 5 have contact with the strings 6. Smooth shaft 7 is installed under the strings in contact with them on the other side relative to the distribution rings. Strings 6 are limited in moving up ,, down and sideways. Asterisks 4 have rounded protrusions and grooves along their contour. On the sides of the protrusions on the asterisks there are vanes, rings 5 are placed between the asterisks. Each subsequent sprocket is mounted on a shaft offset by 45 °. Prefabricated 8 (leather) moving on the strings b of the conveyor 1 approaches the guide shaft 3, which rotates towards the movement of the skin 8 and the BbiCTynaNM strings and sprockets 4, seizes and transfers the skin 8 through itself to the moving strings 6 or to the next - conveyor 2. In this case, the conveyor strings 6, bounded on top by dividing rings 5j on the sides by asterisks 4 and on the bottom by a smooth shaft 7j, continue to move with a certain interval in a given direction.

The invention allows for reliable transportation of leather, eliminating dips and zapadaki leather between the strings during transmission from one conveyor to another, which will improve the quality of treatment of red, for example, with top dyeing. The offset of the sprockets when mounted on the shaft by 45 ° ensures a smooth entry of the leathers and eliminates the possibility of throwing the front edge of the skin.

Claims (2)

Claim 1. A device for moving the leather semi-finished product between working machines, comprising string conveyors spanning the drive shafts and located in one plane, and means for transferring the skin from one conveyor to another is made in the form of a guide shaft placed perpendicular to the direction of the strings and bearing rigidly fixed supporting elements located between the strings, characterized by the fact that, in order to ensure reliable operation during the transition of the skin from one string conveyor to another, In order to hold the conveyor strings in a predetermined position, the means for transferring the skin from one conveyor to another has an additional JJ shaft located below the conveyor strings parallel to the guide shaft and displaced relative to it in the direction of movement of the strings while the supporting elements are shifted by one pitch relative to the other asterisks with rounded protrusions and depressions with blades placed on both sides of the protrusions, and sprocketing rings of stars; The linear velocity of the protrusions of the stars to the speed of the strings is driven within. 2. The device according to claim 1, about tl and -. The fact that the star drive is made so that they can rotate in the direction opposite to the movement of the strings. rig.2 -And 5 & .J AT Compiled by D.Lihachev Editor N.Kishtulinets Tehred D.
