BACKGROUND OF THE INVENTION
The present invention relates to a transfer jack (hereinafter referred to as TR jack) having a loop locking portion formed at the tip, a flat knitting machine provided with a transfer mechanism using the TR jack, and a transfer method between the TR jack and the needle. About.
[0002]
[Prior art]
A pair of front and rear needle beds each holding a needle in a groove on the upper surface so as to be movable back and forth, and one or both of the needle beds are configured to be movable to the left and right with respect to the other needle bed; Japanese Patent Registration No. 2794144 discloses a flat knitting machine provided with a TR jack bed on a needle bed for holding the TR jack in a groove formed on the upper surface thereof so as to be able to move forward and backward. In the flat knitting machine of the publication, the TR jack bed and the needle bed are configured to be relatively rackable in the longitudinal direction, and loops between the needles of the front and rear needle beds and between the needle of the needle bed and the TR jack of the TR jack bed are arranged. Can be delivered. By transferring the loop locked to the needle of the needle bed to the TR jack of the TR jack bed, racking the TR jack bed, and then moving the loop locked to the TR jack to the needle of the needle bed, The needle can be transferred to the side needle of the needle that has locked the loop.
[0003]
FIG. 12 shows the movement of the needle and the TR jack at each stage when the loop is transferred from the TR jack to the needle. In the figure, 141 is a needle, 143 is a TR jack, and 145 is a loop. FIG. 12a shows a state in which the TR jack 143 has received the loop 145 from the needle 141 in the previous course knitting, and the TR jack 143 is in a position where it has advanced to the tooth mouth, and is associated with the loop locking portion 143a formed on the TR jack tip side. The loop 145 to be stopped is in a position where it can be transferred on the mouth.
[0004]
Next, FIG. 12 b advances the needle 141 of the needle bed before receiving the loop 145 to insert the hook 141 a into the loop 145 locked to the loop locking portion 143 a of the TR jack 143. Subsequently, as shown in FIGS. 12 c and 12 d, the TR jack 143 is moved backward to release the loop 145 from the TR jack 143, and is deposited in the needle 141. FIG. 12e shows that the needle 141 is retracted and the loop 145 is captured by the hook 141a and the transfer is completed.
[0005]
However, when the TR jack 143 is retracted in FIGS. 12c and 12d, the loop 145 may be attracted to the retracting TR jack 143. In such a case, the hook 141a is retracted when the needle 141 is retracted in FIG. 12e. Thus, the loop 145 cannot be captured and a drop stitch 145a is generated. There are several possible causes for drop stitching. For example, when the TR jack 143 is formed in such a shape that the loop 145 cannot be smoothly pulled out from the loop locking portion 143a, the loop is easily drawn, and in particular, when the knitted fabric is knitted with a knitting yarn having low elasticity. If the loop is pulled by the TR jack 143, the loop remains in the pulled state even after the TR jack is pulled out, and the drop stitch is generated without returning to the original state.
[0006]
If the loop is cleared only by reversing the TR jack, the loop will be cleared if the TR jack is not retracted to a position where the tension applied to the loop exceeds the tension at which the loop is to be lowered. Not. Therefore, when the knitting is performed by setting the lowering tension to be strong, or when the knitting is performed by setting a small value and forming a fine loop, the load applied to the loop is large. In particular, when transferring from the TR jack to the needle between the TR jack and the needle of the needle bed below the TR jack, there is nothing to regulate the movement of the loop in the direction in which the TR jack moves backward, and in the direction in which the TR jack moves backward. By moving, the loop formed in the front course of the loop locked to the TR jack moves downward along the back surface of the needle, and the tension that pulls the loop locked to the TR jack downward increases. Therefore, compared with the case of transferring between the needles of the needle bed facing the TR jack, the loop is not cleared unless the TR jack is moved back to a position further away from the tooth opening, and the loop is stretched or cut. There is a risk.
[0007]
In view of the above problems, an object of the present invention is to disclose a transfer jack capable of reliably transferring a loop, a flat knitting machine including a transfer mechanism, and a transfer method.

[0019]
Hereinafter, the operation of the flat knitting machine of this embodiment will be described. In the flat knitting machine of the present embodiment, the loop clear member 55 is controlled to the operating position at the transfer between the TR jack bed 9 and the needle bed (the front bed 3a in the present embodiment) below the TR jack bed 9. And the needle bed (the rear bed 3b in this embodiment) facing each other is controlled to the rest position.
The transfer between the TR jack bed 9 and the front bed 3a will be described with reference to FIGS. 4 and 5 show the transfer from the needle to the TR jack between the TR jack bed 9 and the front bed 3a, and FIGS. 6 and 7 show the transfer from the TR jack to the needle. In the transfer from the needle 19a to the TR jack 7, the TR jack body 53 and the loop clear member 55 move from left to right in FIG. When the TR jack main body 53 and the loop clear member 55 reach (1), both the TR jack main body 53 and the loop clear member 55 are located at the last retracted position (FIG. 5a). The butt 69 of the TR jack main body 53 thus brought into contact with the actuator 99 is advanced from the track 101 to the track 103 (FIG. 5b), and the bat 69 of the TR jack main body 53 not selected for transfer maintains the track 101. . At the position (3), the butt 67a of the TR jack main body 53 comes into contact with the cam 95, the TR jack main body 53 advances toward the loop 107 locked to the tongue 41 through the track 105, and then the loop is cleared. The member 55 is advanced toward the loop 107 together with the TR jack main body 53 (FIG. 5c). At the position (4), the TR jack main body 53 reaches the most advanced position, and at the same time, the slider 29 of the needle 19a starts to descend, and the loop 107 moves from the slider 29 to the loop locking portions 63a and 63b of the TR jack main body 53. (Fig. 5d).
[0020]
After the above knitting, the carriage is reversed and the front and rear needle beds are racked so that the needle that receives the loop 107 locked to the TR jack 7 faces the TR jack 7, and then the needle of the front bed 3a from the TR jack 7 Transfer to 19a. The transfer from the TR jack 7 to the needle 19a of the front bed 3a will be described with reference to FIGS.
In the transfer from the TR jack 7 to the needle 19a, the TR jack main body 53 and the loop clear member 55 move from right to left in FIG. In the position of (5) in FIG. 6, the hook 39 of the needle 19a that receives the loop 107 has been advanced into the loop that is locked to the TR jack body 53, and the loop clear member 55 is controlled to be in the protruding position. The cam 91 is advanced to a position where it is engaged with the cam 87 (FIG. 7a). At the position {circle around (6)}, the loop clear member 55 is advanced to the most advanced position by the cam 87, and the loop 107 having the loop clear action surface 79 stretched over the loop engaging portions 63a, 63b is connected to the loop engaging portions 63a, 63b. The loop 107 is transferred from the TR jack 7 to the needle 19a (FIG. 7b). At the position {circle over (7)}, the TR jack main body 53 is retracted and the engaging portion 77 of the loop clear member 55 comes into contact with the TR jack main body 53, so that both the TR jack main body 53 and the loop clear member 55 are retracted (FIG. 7c). At the position {circle over (8)}, the TR jack main body 53 and the loop clear member 55 are both retracted to the last retracted position, and the transfer from the TR jack 7 to the needle 19a is completed (FIG. 7d).
[0021]
Next, the transfer between the TR jack bed 9 and the rear bed 3b will be described. In the transfer from the needle 19b to the TR jack 7, the control of the TR jack main body 53 and the loop clear member 55 is common to the transfer between the TR jack bed 9 and the front bed 3a. Only the transfer from the TR jack 7 to the needle of the rear bed 3b will be described with reference to FIGS. In FIG. 8, the TR jack main body 53 and the loop clear member 55 move from right to left. When the TR jack main body 53 and the loop clear member 55 reach (1) in FIG. 8, the hook 39 of the needle of the rear bed 3b is placed in the loop 107 transferred from the rear bed 3b to the TR jack 7 by the knitting of the front course. Is advanced (FIG. 9a). At this time, the loop clear member 55 is controlled so that the cam 91 is in the retracted position, and does not interfere even if the needle 19b of the rear bed 33b rises to the maximum. Subsequently, the needle 19b starts to descend at the position {circle around (2)}, but the TR jack main body 53 and the loop clear member 55 maintain the positions as they are (FIG. 9b). During the period from (2) to (3), the TR jack main body 53 starts to be retracted, the loop clear member 55 is at the position 9b, and the loop clear operation surface 79 is held without being pushed out to the loop 107. . As the TR jack body 53 is further retracted, the engaging portion 77 of the loop clear member 55 comes into contact with the TR jack body 77, and the TR jack body 53 and the loop clear member 55 are retracted (FIG. 9c). At the position {circle around (4)}, both the TR jack main body 53 and the loop clear member 55 are retracted to the last retracted position, and the transfer from the TR jack 7 to the needle 19b is completed. (FIG. 9d) In this embodiment, as shown in FIG. 10, the loop clear action surface 79 is formed in a shape cut into an arc shape, and the loop locking portions 63a and 63b of the TR jack main body 53 in FIG. The loop 107 to be stopped is formed at a position lower than the locus XX of the deepest portion of the loop clear operation surface 79. Therefore, when the loop 107 abuts against the loop clearing surface 79, the loop 107 pushes out in the direction of the arrow Y rising from the deepest side of the loop clearing surface 79, that is, from the loop locking portions 63a and 63b of the TR jack body 53. Thereby, the loop 107 can be smoothly cleared from the loop locking portions 63a and 63b. The shape of the loop clear operation surface 79 is not limited to the circular arc shape described above, and may be any shape that can smoothly push the loop 107 out of the step portions 65 of the loop locking portions 63a and 63b.
[0022]
<Second Example>
Next, an embodiment in which a mechanism for reducing the load applied to the loop by combining the forward / backward movement of the loop clear member and the swinging of the TR jack body will be described with reference to FIG. In the second embodiment, concave cam surfaces 117 and 118 that contact the tail 115 of the loop clear member 113 on the upper surface of the TR jack main body 111, and the tip of the loop clear member in the groove that accommodates the loop clear member 113 of the TR jack main body 111 are used. And a cam surface 119 that abuts and a slope 123. A slope 125 is formed on the loop clear member 113. The same control cam as that in the first embodiment is used.
[0023]
The case of transferring the operation of the second embodiment from the TR jack body 111 to the needle 129 of the front bed will be described as an example. In the second embodiment, when the loop clear member 113 is at the most advanced position and the most retracted position with respect to the TR jack body 111, both the TR jack body 111 and the loop clear member 113 are in the horizontal state (FIGS. 10a, 10b, and 10c). . When the TR jack main body 111 moves backward, the loop clear member 113 advances relative to the TR jack main body 111, and in the process of moving from the last retracted position to the most advanced position with respect to the TR jack main body 111, the TR jack main body tip is moved to TR. The TR jack body 111 is swung in a direction to lower the tip of the TR jack main body 111 by contacting the cam surface 119 on the bottom surface of the housing groove in the jack (FIG. 10d). At this time, the tail 115 of the loop clear member 113 moves along the cam surface 118 of the TR jack main body 111, and the TR jack main body 111 is swung clockwise. Further, when the TR jack main body 111 is further retracted, the engagement portion 115 of the loop clear member 113 is brought into contact with the cam surface 117 of the TR jack main body 111, so that the TR jack main body is swung counterclockwise. When the main body 111 is in a horizontal state, the loop clear member 113 reaches the most advanced position with respect to the TR jack main body 111, and pushes out the loop 131 from the loop locking portion 121 (FIG. 10e). Thereafter, the loop clear member 113 maintains the most advanced position with respect to the TR jack main body 111, the TR jack main body 111 moves backward, and the transfer is completed.
[0024]
As described above, in the second embodiment, when the TR jack main body 111 moves backward, the TR jack main body 111 is swung so that the loop 131 can be easily removed from the stepped portion 133 of the loop locking portion 121. Since the position of the loop can be lowered, the load on the loop 131 can be reduced.
In the second embodiment described above, the case where the TR jack main body 111 is controlled by the cam that moves the TR jack main body 111 and the loop clear member 113 in the forward / backward movement direction has been described. It is also possible to control the TR jack body 111 by providing a cam that pushes down and a cam that pushes down on the upper surface of the rear end portion of the TR jack body 111.
[0025]
In the above embodiment, a TR jack called a perelin type is used, in which two elastic plate members are extended, a loop locking portion is formed at the extended tip, and the tip is elastically closed. The invention is not limited to the above-described perelin type TR jack, but in the case of a TR jack called a blade type in which a transfer blade formed by an elastic plate-like member is attached to the side surface of a TR jack main body constituted by a non-elastic member. Can also be implemented. In the above embodiment, the TR jack main body and the loop clear member have a two-layer structure, but the TR jack main body is composed of two elastic plate-like members each having a loop engaging portion and two elastic elastic members. It is also possible to have a three-layer structure by sandwiching a loop clear member between plate-like members. Moreover, in the said Example, although the loop clear member is linearly moved, you may rock a loop clear member so that a loop clear action surface scoops up a loop from a loop latching | locking part. In the above embodiment, the tip of the loop clearing surface of the loop clearing member is configured to advance to a position where it overlaps with the tip of the TR jack main body, but it can be pushed to the loop locked by the loop locking portion. It only has to be able to advance.
