Abstract
The patent belongs to the field of a flat knitting machine, aiming at providing an automatic control device of a needle lifting cam (55) and improving the automation degree of the flat knitting machine. The front part and the rear part of the flat knitting machine head are respectively provided with a set of needle lifting cam (55) control device; the flat knitting machine comprises an motor (55) used for pulling the needle lifting cam (55), a gear wheel (52), a rack (54), a cam lever (53), a steel ring (531), a needle lifting cam (55) plate, a machine head cam soleplate (56), a photoelectric switch (31), a washer (32) and a computer control system. After the patent is installed on the flat knitting machine, the four needle lifting cams (55) at the front part and the rear part of the machine head are automatically controlled to be lifted or dropped, thus increasing the work efficiency and relieving the labor intensity of workers.
Description
Affiliated technical field
This patent belongs to a kind of flat machine field, especially is applied in the rise cam 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 can not control rise cam (55) automatically, head has former and later two cam base plate (56), two rise cams (55) about being equipped with on each cam base plate (56), four rise cams (55) altogether, Nose Left or when mobile, by mentioning or putting down each rise cam (55), control and whether the knitting needle under the head is boosted, participate in knitting, on hand knitting machine or needle adder, rise cam (55) needs a large amount of manual operationss by manually mentioning or putting down, and influences operating efficiency like this and increases 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, and this straight-bar machines basic function just should be able to be controlled rise cam (55) automatically, to improve more automaticity.
Summary of the invention
This patent is meant provides a kind of rise cam (55) automaton, improves the automaticity of straight-bar machines.Front and back two parts on flat-knitting machine head, each installs cover rise cam (a 55) control device, when head moves braiding, whether the knitting needle that is used for controlling respectively on the front and back needle plate under the head works, comprised the motor (51) that is used to spur rise cam (55), gear (52), tooth bar (54), culdy (53), steel ring (531), rise cam (55) plate, head cam base plate (56), optoelectronic switch (31), shield sheet (32) and computerized control system.
A rise cam (55) control device respectively is installed on the head of front and back, and it has comprised optoelectronic switch (31), shield sheet (32), motor (51), gear (52), culdy (53), steel ring (531), tooth bar (54), rise cam (55), head cam base plate (56); Hole at each rise cam (55) top, steel ring (531) is entangled rise cam (55) (as Fig. 3), steel ring (531) also entangles the aperture (532) at culdy (53) two ends simultaneously, culdy (53) is connected with tooth bar (54), and tooth bar (54) contacts and interlock with the gear (52) of motor (51); The positive and negative rotation of motor (51) gear (52) promotes tooth bar (54) and culdy (53) moves up and down, thus mention simultaneously or put down about two rise cams (55).
Shield sheet (32) is installed on the tooth bar (54), and in the time of in shield sheet (32) moves to optoelectronic switch (31) groove, optoelectronic switch (31) switching signal changes, and computerized control system thinks that rise cam (55) has been lifted to dead-center position.
This patent after installing on the straight-bar machines, can the robot brain head before and after the mentioning or put down of four rise cams (55), can control high pin of braiding and low pin knitting needle, can accomplish conversion shirt sheet tissue and weave at any time, matching computer control system and other turn over needle device, realize barring-on, remove pin, choose the hole, turn round the position and turn round sophisticated functions such as rope, thereby to enhance productivity, alleviate labor strength, reduce the production cost of factory.
Description of drawings
Below in conjunction with drawings and Examples this patent is further specified.
Fig. 1 is that rise cam is raised view;
Fig. 2 is that rise cam is put down view;
Fig. 3 is the rise cam partial enlarged view.
Among Fig. 1
Optoelectronic switch (31), shield sheet (32), motor (51), gear (52), culdy (53), steel ring (531), culdy aperture (532), tooth bar (54), rise cam (55), head cam base plate (56), rise cam lid (551), rise cam aperture (552).
The specific embodiment
1, motor (51) can be a stepper motor, servomotor or other motor, and its positive and negative rotation can accurately be controlled.
2, the rotation of motor (51) is to be controlled by computer.
3, when Computerized flat knitting machine is started shooting, rise cam (55) before and after at first will mentioning, and make shield sheet (32) shield on the tooth bar (54) live optoelectronic switch (31), at this moment computerized control system is as the basic zero of rise cam (55) height.
4, when needs only weave high pin knitting needle, rise cam (55) need be pushed to the suitable withdrawal of needle height that is higher than low pin knitting needle pin heel, at this moment can not boost low pin knitting needle, only weave high pin knitting needle.
5, when needs weave high pin and low pin knitting needle, rise cam (55) need be put down position, the end, can boost high pin and low pin knitting needle.
6, before and after needs weave simultaneously during the needle plate knitting needle, as three flat, Siping City, or hole bar etc. need all put down front and back rise cam (55) when organizing, and rise cam (55) just can boost the knitting needle of the normal working position of worker, participation work.
7, when the braiding one-sided composition, two rise cams in front (55) need be put down, two rise cams in back (55) are mentioned.
8, when braiding unit tube hollow tissue, before the Airplane Nose Right braiding, two rise cams in front (55) need be mentioned, next two rise cams (55) are put down, and before the Nose Left braiding, two rise cams in front (55) need be put down, next two rise cams (55) are mentioned, repeatedly circulation.
9, when four rise cams in front and back (55) when mentioning simultaneously, empty head moves, and does not weave, and head is movable to the position that needs and carries out barring-on, and operations such as pin are removed in narrowing.
