CS268717B1 - Locking block for knitting machines - Google Patents

Abstract

A cam assembly for knitting machings being characterized in that from the side of the needle bed (12) there is a recess (14) in the cam block (1), the recess (14) being limited by walls, in said recess there are cams (8 to 11) provided with through-holes (15) through which passes only one fixing element (13) which holds the cams in the cam block. The walls (2 to 6) of the recess (14) in the cam block (1) limit angular position for cylinder, dial or sinkers cams, height position of cylinder cams and radial position of dial or sinker cams, radial position of cylinder cams and height position of dial or sinker cams. Fixing by only one fixing element (13) is performed so that the cylinder cams can radially and dial or sinker cams can vertically move between the needle or sinker and upper wall of the recess within the limits of the gap between the fixing element and the surface of the through-hole in the cams.

Description

The invention relates to locks for knitting machines, namely to their fixing in lock blocks in knitting machines.

It is known that the locking parts from which the paths for the windows of needles or sinkers are formed are screwed or riveted to the parts carrying the locking parts, whereby their position is provided by pins, pins or a plurality of screws which must be precisely positioned.

The disadvantage of this embodiment is that when replacing the lock parts, it is necessary to unscrew and screw a larger number of screws, and in the case of multi-lane machines, a considerable number of screws.

Another disadvantage is that the exact reproducibility of the position of the lock parts is not ensured and the replaced lock parts need to be checked and adjusted. Such replacement of locks is laborious and lengthy.

The above-mentioned drawbacks are eliminated by the device according to the invention, characterized in that a recess bounded by the upper and lower walls, side walls and the rear wall is provided from the needle bed of the machine into the lock block, into which locks provided with through holes are passed. the only fastening screw that holds the locks in the lock block. The top and bottom walls of the recesses in the cylinder lock block define the height position of the cylinder locks, the side walls of the recesses define the angular position of the cylinder locks. The right and left walls of the recesses in the disc lock block define the radial position of the disc locks, the side walls (not shown) define the angular position of the disc locks. There is a gap between the bolt holding the locks in the lock block and the wall of the through hole formed in the locks allowing movement of the locks between the knitting elements and the recess wall in the lock block opposite the knitting elements.

An advantage of the device according to the invention is that when changing the locks, only one single screw in the lock block needs to be unscrewed, thereby releasing all the locks in the block and after replacing the single screw again. The exact position of the locks is given by the top, right, bottom, left and side walls of the recesses in the lock block.

The device according to the invention is shown in the drawings, wherein FIG. 1 shows a front view of a lock block with locks cooperating with knitting elements in a cylindrical bed; FIG. 2 shows a side view of the same lock block with locks; plate or platinum bed.

According to FIGS. 1 and 2, the locks 8, 9, ДО, ДД cooperating with the knitting elements 7, 24, 25, 26 in the cylindrical bed Д2 are inserted into the recesses Д4 in the lock block Д which is fastened to the cylinder lock carriers 22 in a known manner. The recess Д4 is formed into the lock block 1 from the side of the cylindrical bed Д2 and is formed by an upper wall 2, a lower wall 3, side walls 4 and 5 and a rear wall 6. The upper wall 2 and lower wall 3 of the recesses 14 in the lock block 1 the side walls 4 and 5 define the angular position of the locks 8, 9, 10, 11. The locks 8, 9, 10, Д1 are attached to the lock block Д by one single fastening element, in this example made with the screw DZ, which passes through the through holes 15 made in the locks 8, 9, ДО, ДД and is screwed into the lock block 1. Between the screw DZ and the wall of the through hole D5 in the locks 8, 9, ДО, Д Д is the clearance that allows the movement of the locks 8, 9, ДО, ДД between the knitting elements 7, 24, 25, 26 in the cylindrical seat 12 and the rear wall 6 of the recess 14 in the lock block 1. , 9, 10, 11 and screwed into the lock block Д prevents the release of the locks 8, 9, 10, 11 from the recesses 14 in the lock block Д when removed from the cylinder lock supports 22.

After unscrewing the screw 13 from the lock block 1, the locks 8, 9, ДО, ДД are loosened and can be re-arranged or replaced for changing the path of movement of the knitting elements 7, 24, 25, 26 in the cylindrical bed Д2.

According to FIG. 3, the cams Д6, 17 cooperating with the knitting elements Д9 and 23 in a plate or platinum bed 18 fixed in a manner not shown to the plate carrier
