Description

The density triangular automaton

Affiliated technical field

This patent belongs to a kind of flat machine field, especially is applied in the density triangular automaton on a kind of straight-bar machines that automatic needle-turning and loop-transferring arranged.

Background technology

At present, traditional hand knitting machine and the semi-automatic straight-bar machines such as pin that add, all automatically control of density triangle (58) thus regulate shirt sheet density and thickness automatically, head has former and later two cam base plate (580), two density triangulars (58) about being equipped with on each cam base plate (580), four density triangulars (58) altogether, when Nose Left moves delegation, the height of density triangular (58) the control knitting needle on the right, thereby the coil size of control braiding sweater sheet, coil size directly has influence on the density of shirt sheet and the thickness of shirt sheet.On hand knitting machine or needle adder, density triangular (58) is by artificial adjustment, when changing the braided fabric weave at every turn, the density triangular hand-manipulated (58) that needs, influence operating efficiency like this and increase labour intensity, particularly at present sweater factory be difficult to advertise for workers situation under, this just needs and a kind ofly can weave and receive the straight-bar machines that flower is received various functions such as neck automatically, this straight-bar machines basic function just should be able to control of density triangle (58), cooperate various work such as various weaves of conversion and cooperation narrowing barring-on, to improve more automaticity.

Summary of the invention

This patent is meant provides a kind of density triangular (58) automaton, improves the automaticity of straight-bar machines.

Two sides, front and back on flat-knitting machine head, each installs two cover density triangular (58) control device, when head moves braiding, be used for the height of control of density triangle (58) line ball respectively, comprised handpiece case (13), head macropore (131), head aperture (132), cam base plate (580), density triangular (58), gear (581), tooth bar (582), screw (5822), cam base plate stroke groove (583), sliver (584), sliver screw hole (5841), rise cam lid (55), motor (59), optoelectronic switch (591), shield sheet (592), motor mounting plate (593), motor fixed screw (594), following shaft (595) and last shaft (596) and computerized control system.

Two density triangulars (58) automaton respectively is installed on the head of front and back, its method is that tooth bar (582) respectively is installed on each density triangular (58) sliver (584), tooth bar (582) contacts with the gear (581) of motor (59) and interlock, the positive and negative rotation of motor (59) gear (581) promotes tooth bar (582) and density triangular (58) moves in cam base plate stroke groove (583), thereby control of density triangle (58) highly, when head normally weaves, the height of density triangular (58) will influence coil size and Density;

On handpiece case (13), be drilled with aperture (132), be used for motor (59) is fixed on above the handpiece case (13); And on handpiece case (13), cutting macropore (131), and be used for conveniently putting the gear (581) of motor (59) into head inside, and contact and closely interlock with tooth bar (582), can not become flexible; Motor (59) gear (581) can pass through to adjust motor (59) and motor fixing plate position with the degree of tightness of tooth bar (582) interlock, and motor screw (5822) is locked.

Motor (59) has two up and down shafts, and lower shaft is installed gear (581), and last axle is equipped with shield sheet (592), and motor (59) axle rotation driven gear (581) rotates synchronously with shield sheet (592);

In the time of in shield sheet (592) moves to optoelectronic switch (591) groove, optoelectronic switch (591) switching signal changes, and computerized control system thinks that density triangular (58) has been pulled to dead-center position;

This patent is after installing on the straight-bar machines, the height of the line ball of four density triangulars (58) can be accomplished the density and the coil size of conversion shirt sheet at any time before and after the energy robot brain head, and matching computer control system and other turn over needle device, realize barring-on, remove pin, choose the hole, turn round the position, with turn round rope and wait sophisticated functions, thereby to enhance productivity, alleviate labor strength, reduce the production cost of factory.

Among the figure

Handpiece case (13), head macropore (131), head aperture (132), cam base plate (580), density triangular (58), gear (581), tooth bar (582), screw (5822), cam base plate stroke groove (583), sliver (584), sliver screw hole (5841), rise cam lid (55), motor (59), optoelectronic switch (591), shield sheet (592), motor mounting plate (593), motor fixed screw (594), following shaft (595) and last shaft (596);

The specific embodiment

1, motor can be a stepper motor, servomotor or other motor, and the accuracy of its positive and negative rotation is controlled by computer.

2, when Computerized flat knitting machine is started shooting, four density triangulars (58) before and after at first will boosting, and make shield sheet (592) shield live optoelectronic switch (591), at this moment computerized control system is as the basic zero of density triangular (58) height.

3, when the knitting needle of needs braiding front and back, density triangular (58) need be pushed into the height that the operator sets, motor this moment (59) locking density triangular (58) makes density triangular (58) be fixed on the position of setting, and density triangular (58) normally participates in work.

4, when the empty head of needs moved, do not weave this moment, and suitable the raising of density triangular (58) this moment in order to avoid the head translational speed is too fast, and breaks the coil on the knitting needle; The knitting needle that has particularly just carried out behind the barring-on has under the situation of two coils, perhaps the height of knitting needle may rugged situation under; During normal the braiding, density triangular (58) is got back to normal braiding height again.

5, when the needs lasso or turn round in the special action such as rope, the specific several coils in the delegation need be strengthened especially or put little; Method is: when head density triangular (58) wove coil to appointment, head suspended, and density triangular (58) temporarily is suitably adjusted the height of line ball up and down, thereby makes specific coil size change; Again density triangular (58) is recalled to normal height afterwards.
