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 a cam assembly for knitting machines, particularly to fix the cams in the cam blocks in knitting machines.
- Cam elements which limit the tracks of needle or sinker butts are normally fixed to carrying members by screws or rivets, while adjustment of their position is performed by pins or other screws which must be positioned very precisely. For changing the cam elements it is necessary to unscrew and to screw a number, in case of multi-track machines a large number of screws. Another disadvantage is that precise reproducibility of the position of cam elements is not guaranteed and that exchanged cam elements must be checked and adjusted. Said exchange of cams is laborious and time demanding.
- It is the object of the invention to provide a cam assembly, in which the cam elements can be changed quickly and in which the adjusting of the new cam elements can be done very simple.
- This object will be solved according to the invention by a recess in the cam block is disposed from the side of the needle bed of the machine, said recess being limited by upper and lower walls, side walls and rear wall, in said recess there are cams provided with through-holes through which passes an only one fixing screw holding the cams in the cam block. The upper and lower walls of the recess in the cam block limit the height position of cylinder cams and the side walls of the recess limit the angular position of cylinder cams. The right and left walls of the recess in the cam block limit radial position of dial cams, not shown side walls limit angular position of dial cams. Between the screw holding the cams in the cam block and the surface of the through-hole in the cams there is a gap permitting a motion of the cams between the knitting elements and the wall of the recess in the cam block opposite to said knitting elements.
- The advantage of the arrangement according to the invention is that when changing the cams it is necessary to unscrew only one screw in the cam block what releases all the cams in the block and after the exchange to screw-in said only one screw again. Precise position of the cams is given by upper, right, lower, left and side walls of the recess in the cam block.
- Further advantages and features of the invention will be seen from the following description of an example shown in the drawings, where
- Fig. 1 is a side view of a cam block with cams cooperating with knitting elements in the cylinder,
- Fig. 2 is a front view of the same cam block with the cams,
- Fig. 3 is a side view of a cam block with cams cooperating with knitting elements in a dial or a sinker ring.
- According to Figs. 1 and 2, cams 8 to 11 cooperating with knitting
elements cylinder 12 are located in arecess 14, in acam block 1 which is fixed to aclyinder cams carrier 22. Therecess 14 is made in thecam block 1 from the side of thecylinder 12 and saidrecess 14 is limited by anupper wall 2, alower wall 3,side walls 4 and 5 and arear wall 6. Theupper wall 2 and thelower wall 3 of therecess 14 in thecam block 1 limit the height position of cams 8 to 11 and theside walls 4, 5 limit the angular position of the cams 8 to 11. The cams 8 to 11 are fixed to thecam block 1 by only one fixing element, in this exemplary embodiment by only onescrew 13 which passes through the through-holes 15 made in the cams 8 to 11 and screwed into thecam block 1. Between thescrew 13 and the wall of the through-hole 15 in the cams there is a gap which permits a motion of the cams between theknitting elements cylinder 12 and therear wall 6 of therecess 14. Thescrew 13 passing the cams 8 to 11 and screwed into thecam block 1 prevents a releasing of the cams 8 to 11 from therecess 14 when thecam block 1 is taken out from thecylinder cams carrier 22. - After unscrewing the
screw 13 from thecam block 1 the cams 8 to 11 are released and it is possible to change their arrangement or to exchange them when it is necessary to change the track for the motion of knittingelements cylinder 12. - In the embodiment of Fig. 3,
cams knitting elements sinker ring 18 fixed to adial carrier 20, are located in arecess 14 in acam block 1 which is fixed to thedial cams carrier 21. Therecess 14 is made in thecam block 1 from the side of thedial 18 and it is limited byright wall 2,left wall 3, not shown side walls andupper wall 6. Thecams screw 13 which passes through the through-holes 15 made in thecams cam block 1. A clearance between thescrew 13 and the wall of the through-hole 15 permits motion ofcams knitting elements dial 18 and theupper wall 6 of therecess 14 in thecam block 1. Radial position of thecams walls recess 14 in thecam block 1, angular position of thecams recess 14 in thecam block 1.
