Description
Technical field
The present invention relates to be used for the circular knitting machine of hosiery or analog.
Background technology
The single-needle and the links-links circular knitting machine that are used for hosiery or analog are known.
Open head jersey machine consists essentially of syringe, and this syringe has vertical axis, and on the side of this syringe a plurality of axial grooves is arranged, and each axial groove holds a pin, and this pin can be actuated to alternating movement along corresponding axial groove, thereby forms knitwear.Pin is provided with heel substantially, this heel is radially outstanding from the corresponding axial groove of syringe, by providing a plurality of pin actuating cams to activate pin, these pin actuating cams are arranged to around syringe, and integrally limit the path, these paths are formed with rising part, stop or horizontal component and sloping portion, and when syringe is actuated to when rotating around syringe self axis with respect to the pin actuating cam, these paths can be followed by the heel of pin.
The links-links circular knitting machine that is used for hosiery or analog generally includes bottom cylinder and top cylinder, bottom cylinder has vertical axis, and top cylinder is arranged on bottom cylinder top and coaxial with bottom cylinder, and described syringe can be actuated to each other and rotate around common axis rigidly.
A plurality of axial grooves are formed on the side of bottom cylinder and on the side of top cylinder.The axial groove of top cylinder is aimed at the axial groove of bottom cylinder.Sliding part is contained in each axial slots of bottom cylinder and in each axial slots of top cylinder.Between two syringes, promptly at knitting areas, a pin is arranged in each axial groove, this pin is provided with two ends or head, is respectively head portion and head portion; Can wish to form flat pin or purl according to people, thus with described pin move into bottom cylinder carry out with end it on knitting, thereby perhaps carry out knitting with its lower end this pin immigration top cylinder.
Because pin does not have heel, so by being arranged on the sliding part in the bottom cylinder or activating pin by the sliding part that is arranged in the top cylinder, this depends on will form flat pin or purl.
The sliding part that uses at the links-links circular knitting machine that is used for hosiery or analog at present is made of the elongated sheets body usually, this elongated sheets body has first vertical side, and this first vertical side is designed to be positioned on the side that is formed on bottom cylinder or on the bottom of the axial groove on the side of top cylinder.
Described sliding part also is provided with two heels, and these heels are spaced from each other along the longitudinal extension scope of sliding part, and laterally outstanding from second vertical side of sliding part, second vertical side opposite with first vertical side to.
Described heel is used for producing sliding part along the moving of the corresponding axial groove of bottom cylinder or top cylinder, thus cause knitting machine various types of knitting in the pin that is associated with described sliding part of actuating, or pin is transferred to another syringe from a syringe.
Sliding part is in bottom cylinder or top cylinder according to sliding part on its first vertical side, promptly also being provided with hook-shaped lug towards holding sliding part that side in the bottom of wherein axial groove, this hook-shaped lug cooperates the head portion or the head portion of pin.
Be provided with a plurality of slider actuation cams around the side of bottom cylinder and around the side of top cylinder, these slider actuation cams limit a series of paths, when syringe is actuated to when rotating around syringe self axis with respect to described cam, the heel of sliding part just cooperates with these paths.The path that is limited by cam is shaped as and causes that sliding part moves along holding the axial groove of sliding part in wherein syringe, and therefore activates the pin that is associated with sliding part.
In order to change the type that therefore actuating of each pin is also changed knitwear that pin produces, must activate transfer to pin heel or sliding part heel, this shifts actuatable pin and is transferred to another path from a path of corresponding actuating cam, and this is normally by in each axial groove, below the pin in open head jersey machine or the sliding part in the bottom cylinder in links-links circular knitting machine below provide a kind of secondary pin or selector to realize, this pair pin or selector also are provided with one or more heels, these heels are can be from the side of syringe radially outstanding cooperating the selector actuating cam, and these selector actuating cams also syringe in the open head jersey machine or the side of the bottom cylinder in the links-links circular knitting machine are provided with.
Selector can be swung on the sagittal plane of the syringe that they were positioned at usually, thereby transfer to the non-operative position from the operating position or vice versa, in this operating position, selector at least one heel in outstanding and its heel from the corresponding axial groove of syringe or bottom cylinder cooperates selector actuating cam, and in the non-operative position, mismatch the selector actuating cam in the corresponding axial groove thereby selector embeds with its heel.
The selector actuating cam has rising part and sloping portion, thereby because syringe rotates around syringe self axis with respect to the selector actuating cam, when the heel of selector cooperates rising part and sloping portion, cause be positioned at the top pin or the rising of sliding part move, directly activate or another path is transferred in the path of its heel from the path that is limited by pin actuating cam or slider actuation cams thereby produce it, perhaps allow the common pin that causes by pin actuating cam or slider actuation cams or the decline of sliding part to move.
At present there are two kinds: rigidity swing selector and elastics wing selector at the employed selector of the circular knitting machine that is used for hosiery or analog.
Rigidity swing selector need be intervened selector it transferred to the non-operative position from the operating position and to transfer to the operating position from the non-operative position.
The elastics wing selector only needs it is transferred to the non-operative position from the operating position usually, because in case thereon to hold it in the action interrupts of non-operative position, because reverse transition will take place the elastic reaction of selecting automatically.
Activate the transfer of selector from the operating position to the non-operative position by selecting arrangement, these selecting arrangement lateral faces are to the syringe of knitting machine, and by selector, these selecting arrangements can change the actuating to pin, therefore change producible knitwear.
In the circular knitting machine that can buy in the market; usually also be provided with additional cams between the pin actuating cam and between the slider actuation cams; these additional cams can along with respect to the radial direction of syringe according to the order campaign; thereby transfer to the non-operative position from the operating position or vice versa; in this operating position; thereby additional cams is cooperated by the heel of pin or sliding part near syringe; and in this non-operative position, thereby additional cams and syringe separate the heel of not interfering pin or sliding part.
In the knitting machine of known type, the rigidity selector cooperates with the selector actuating cam, especially with the cooperating of the rising part of described cam lift pin or sliding part, not always satisfactory, because because the chance phenomenon such as swing, the heel of selector can be thrown off with actuating cam, and is therefore inaccurate or activate pin by halves.For this reason, usually can break or knitting mistake.
In order to attempt to address this problem, be designed to cooperate the heel of the selector of selector actuating cam to have trapezoidal shape, therefore the profile that is designed to the cam that is complementary with heel is shaped, but this solution can't provide the coupling of fully guaranteeing intensity, because under the situation of high actuation speed and fierce vibration, the unexpected disengagement of selector and selector actuating cam can take place still.
Swing selector for elastic type, this problem is more not obvious, because the elastic reaction of selector can be reinforced itself and the cooperating of selector actuating cam, but bigger problem is arranged again for integrally handling selector, because must additional actuator or cam be set in the zone that selector will be in the non-operative position, thereby avoid it to cooperate with the selector actuating cam, this can significantly increase the complexity of knitting machine.
And the existence of movable cam and associated actuators is necessary for producing various knitwear between pin actuating cam and slider actuation cams, but the problem of the structural complexity of the whole knitting machine of remarkable increase is arranged.
And; the existence of these movable cams also forces the actuation sequence that suitable setting will be provided on knitting machine; if knitting machine is shut down suddenly owing to have a power failure; then this actuation sequence can be interfered; and in the tram of recovering to get back to before knitting movable cam; if just do not restarted because knitting machine is not at first got back to the tram of movable cam, the heel of pin or sliding part just may rupture so.
In fact, the existence of these movable cams makes the electronic program of the position of movable cam in the time of must the storage outage being set to knitting machine, and this just constitutes the further complexity that knitting machine is made.
