Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a needle selection device for a flat knitting machine, and the present invention relates to a needle selection device for a flat knitting machine.
Even if the needle selection coil is energized or de-energized, the needle selection coil is configured to be limited to protrusion to a tuck position lower than the knit position at an appropriate time.

(Prior Art) In this specification, a miss position refers to the height of a non-selected needle. Knit position and tuck position are conventionally used terms.

Conventional mechanical needle selection devices for flat knitting machines have various configurations in which the butt provided on the knitting needle or jack is selected from the miss position to the knit position or tuck position. Alternatively, in order to have a structure in which the jack can be projected to either the knit position or the tuck position using a plunger that can select needles one by one,
Since the needle selection coil cannot have an outer diameter within one pitch or -pinch of the knitting needle arrangement, it is difficult to provide the needle selection coil on the needle bed side of the horizontal Ii machine. For this reason, there is no needle selection device installed on the needle bed side that allows the plunger, whose protrusion is controlled by the needle selection coil, to be placed in the knit position or in the tuck position.

(Problems to be Solved by the Invention) The present invention has a configuration in which a needle selection device using magnetic force is integrated into a horizontally long case. ! To facilitate attachment to and removal from the knitting needle, and to simultaneously limit the protrusion of the plunger, which is a needle selection member using magnetic force corresponding to each knitting needle or jack, from protruding to the knitting position to the tuck position. The problem was to find a structure that would make this possible, and to make it particularly applicable to stockinette 1lfi, etc., which has a small number of knitting needles.

(Means for Solving the Problems) The present invention is aimed at solving the above-mentioned problems. By making the knitting needles different from each other, the knitting needles are arranged in a horizontally long case in accordance with the arrangement of the knitting needles B-7, and the plungers are arranged inside the case according to the arrangement of the plungers, and the plungers are inserted into each of them.
A needle selection coil is provided that projects and moves each plunger to the knitting position when energized or de-energized individually, and a locking layer or locking recess is provided on each plunger, and the needle selection coil is provided outside the case to move the plunger to the knitting position by energizing the coil. A baffle piece is provided facing the locking layer or locking recess of each plunger to energize or de-energize the needle selection coil and restrict the plunger to protrude movement from the miss position to the tuck position lower than the knit position. It is characterized in that each plunger corresponds to a needle selection lever attached to a large number of knitting needles or a jack of a flat knitting machine.

(Operation of the present invention) The present invention is arranged in a horizontally long case 1 in accordance with the arrangement pitch of the knitting needles by alternating the plungers 12 of the number corresponding to the number of knitting needles or jacks of the horizontal *a several times in the front and back. However, since a needle selection coil is arranged inside the case 1 in accordance with the arrangement of the plungers and moves each plunger 12 protrudingly to the knitting position while individually energizing or de-energizing, the needle selection coil is arranged in the same manner as the arrangement of the plungers. Even if the outer diameter of the needle selection coil 11 is larger than the distance between one pitch of knitting needles, it can be stored in the case 1 and the protrusion movement of the plunger 12 can be controlled by each needle selection coil. Needle selection can be performed by attaching the compact case 1 to a flat knitting machine with a small number of planted row knitting needles.

Further, a locking shoulder 14 or a locking recess a is provided on the plunger 12, and a locking shoulder 14 or a locking recess a is provided on the outside of the case, and a locking layer 14 or a locking recess a is provided on the outside of the case so that each plunger 12 can be selected by facing the locking layer or the locking recess of each plunger in a miss position by energizing the fill. With the energization or de-energization of the needle coil 11, from the miss position ■ to the knit position ■ a lower tuck position ■
Since a baffle piece is provided to restrict the protrusion movement to the tack position, as will be explained in the embodiments below, only the plungers 12 necessary for the - course are protruded to the tuck position ■, and the other plungers 12 are moved to the miss position. It is possible to perform tuck knitting by being fixed to the I, and the present invention, which uses a needle selection coil, can be configured to be suitable for installation on a knitting machine.

(Example) Examples of the present invention will now be described.

In the figure, 1 is a horizontally long case consisting of iron materials 2.3, with a printed wiring board 4 and a yoke plate 5 sandwiched between the iron materials 2.3, and a suction plate 6 placed on the bottom surface to fix the whole. Then, as shown in Fig. 1, vertical holes 7 for inserting coils are provided in the iron material 3 between the yoke plate 5 and the suction plate 6 of the case 1, and the coils are inserted in pairs with slight differences in the front and rear directions. A vertical plunger insertion hole 8, which is concentric with the vertical hole 7 and whose inner diameter is slightly smaller, is provided in the iron material 2 at the upper part of the wiring board 4, and at the upper end of the vertical hole 8 is an ejection hole whose diameter is further reduced. 9
At the same time, a horizontal hole 10 for inserting a baffle piece is formed at the upper end of the vertical insertion hole 8, which is connected to the protrusion hole 9, and extends perpendicularly therethrough as shown in FIG. 1.5.

Apply control. 12 is slidably fitted into the insertion vertical hole 8, the upper end protrudes from the protruding hole 9, the lower end passes through the through hole provided in the printed wiring board 4 and the yoke plate 5, and then inserted into the needle selection coil 11. This is a plunger. In this embodiment, when the needle selection coil 11 is excited, the plunger 1
2 is sucked downward and comes into contact with the suction plate 6 as shown in FIG.
As a result, the upper end is configured to protrude to the miss position (2), and in this state, a certain distance is created below the horizontal hole 10, and the enlarged diameter portion 13 creates a gap between it and the printed wiring board 4.
, an engagement shoulder 14 is formed at the upper end of the enlarged diameter part 13 , the enlarged diameter part 13 is in contact with the inner surface of the insertion vertical hole 8 , and a spring 15 is lifted up to the plunger 12 at the lower end of the enlarged diameter part 13 . The lower end of the spring is brought into contact with the printed wiring board 4.

The number of plungers 12 corresponds to the number of horizontal Ii knitting needles or jacks, and the number of plungers 12 is arranged to match the pitch of the rows of needles on the needle bed.As with the vertical holes 7 and the insertion vertical holes 8, three plungers are provided in the front and rear. The difference is made in the direction, and its mode is shown on the right side of Figure #1.

Since the printed wiring board 4 has a through hole for the plunger 12 to pass through and receives the lower end of the lifting spring 15, the area for wiring is limited, so the wiring board 4 is attached to the lower surface of the suction plate 6 and 15 can be changed to a design in which it is supported by the upper surface of the yoke plate 5.

In the above, the horizontal hole 10 can be provided slightly below the illustrated position. On the other hand, when the plunger 12 is projected to the second F position (2), the enlarged diameter portion 13 must be brought into contact with the lower surface of the ejection hole 9 (1), as shown in FIG. An engagement recess a is provided on the circumferential surface, and when the plunger 12 is placed in the miss position I, the lower edge of the engagement recess a is located at the side hole 10.
It is also possible to set it downward at a certain interval.

As shown in FIGS. 1 to 4, baffle piece coils 21 are attached to both sides of the case 1 in the length direction, and suction pieces 22 protrude upward.
A forked portion 2 is connected to a link 23 having a pin 24 at its upper end, and is provided opposite to a pair of swinging levers 25 and 25 fitted to shafts 25' and 25' on the front and rear sides of the pin 24.

The rear end of the jack 53 from the butt 54 is slidably grasped by the lever, and a spring 58 is attached to the rear end of the needle selection Lenoy 56 to pull it downward. In the case 1, the plunger 12 is brought into contact with any one of the needle selection protrusions 57 of each needle selection lever as shown in the figure, and the solid line in FIG. The butt 54 is shown in the knitting position ■' via the needle lever 56. If the plunger 12 is in the wrong position I, the butt 5
4 is also in the miss position d, and if the protrusion of the plunger 12 from the miss position 2 is restricted by the baffle piece 34 to be in the tuck position 2 as described later, the butt 54 is also in the tuck position 2'.

In the embodiment of the present invention shown in FIGS. 1 to 5, all the needle selection coils 11 are energized to lower all the plungers 12 to the miss position (2) at the end of the course, and then some of the needle selection coils 11 are lowered to the miss position De-energization of the needle selection coil 11 is selectively controlled, and only the plunger 12 whose lower part is inserted into the de-energized needle selection coil 11 is raised by the elasticity of the lifting spring 15 to the knitting position (2).

In addition, in a course consisting of, for example, every fifth plunger 1
2 to the tuck position, all the needle selection coils 11 are energized at the end of the previous course to align them to the miss position I, and then the baffle piece coil 21 is energized, and the suction piece 2 is placed in the tuck position.
2 and the link 23 as shown in FIG. 4, pull the baffle piece coils 29 and 29 with the tension spring 32, and as shown in FIG. De-energization of only the necessary needle selection coils 11 is controlled.

At this time, only the plunger 12 whose lower blade part is inserted into the de-energized needle selection coil 11 protrudes due to the elasticity of the lifting spring 15, but the baffle piece 3 is placed on the engagement shoulder 14 of the enlarged diameter part 13.
