Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stitch holding device for preparing a knitted fabric immediately after being knitted in a flat knitting machine.

[Conventional technology]

It is already known, for example, from Japanese Patent Publication No. 62-20295, to equip a board carried by a knitting carriage with a plurality of sets of presser devices, each consisting of a pair of pressers that alternately change their vertical positions.

[Problem that the invention seeks to solve]

However, in conventional systems in which a plurality of sets of presser devices are provided on a moving board, the vertical position of the presser in each set of presser devices is converted by collision with a conversion actuating device, such as an inclined cam, provided at the reciprocating end of the carriage. Generally, this is carried out by the following method. Therefore, when multiple sets of presser devices are installed in parallel, it is necessary to align each set of presser devices with the conversion actuating device in sequence. It is necessary to increase the amount of movement of the carriage, that is, the amount of movement of the carriage, which is disadvantageous for other knitting operations, and the conversion actuation device is also complicated, which requires a lot of effort for management and maintenance. In the case where an actuating device capable of converting all the pressers in each set of presser devices at once is provided, the structure thereof must become even more complicated, and there has been no proposal for this.

[Means for solving problems]

The present invention eliminates the disadvantages of the conventional means described above, and accurately performs presser conversion operations simultaneously in each presser device in which a plurality of sets of pressers are arranged in parallel using extremely simple means. A pair of pressers are attached to a board that moves along a rail piece installed above and is carried along by a knitting carriage, and that move up and down perpendicularly to the sinker opening of the needle bed and alternately change the vertical position on the outside of both ends of the knitting width. In a device equipped with two or more sets of presser devices arranged in parallel, the sinker opening of the needle bed is attached to a board that moves along a knitting carriage along a rail piece constructed above the front and rear needle beds facing the chevron. In an apparatus equipped with two or more sets of presser devices arranged in parallel, each pair of pressers moves vertically vertically to the knitting width and alternately changes the vertical position on the outside of both ends of the knitting width. is connected to both ends of a rolling piece which is pivotally supported, and the vertical position is mutually changed by the rolling of the rolling piece, and the pressers at the respective connected ends of two adjacent sets of presser devices, A plurality of sets of presser devices are connected to both ends of a swinging lever whose intermediate part is pivoted, and are connected in series by a rolling piece and a swinging lever, and one set of presser devices is located at the frontmost end at the reciprocating end of the carriage. The present invention is characterized by a mechanism in which the vertical position converting operations of all the pressers in the plurality of sets are simultaneously linked only by the vertical position converting operation of the pressers.

[Effect]

In the apparatus of the present invention, a board equipped with a plurality of sets of presser devices arranged side by side moves along a track piece while being carried by a carriage during knitting work. Each set of presser devices is composed of a pair of pressers that can move up and down with respect to the sinker opening at the tip of the needle bed, and both pressers are arranged at both ends of a rolling piece with a holder for both pressers being pivotally supported in the middle, as is well known. The pressers are connected to each other so that the vertical positions of both pressers can be changed by the rotation of the rolling pieces.
Further, at both ends of the reciprocating movement of the carriage, a slope cam or the like is provided as an actuating device for converting the vertical position of the pair of pressers in the presser device, and when the carriage reaches the end of the reciprocating movement, the presser device collides with the converting actuating device. Due to the collision, the presser in the lower moving position moves up, and the presser in the upper moving position changes to the lower moving position, and the knitted fabric is knitted by the presser, which adapts to the change in the direction of travel of the carriage and becomes the lower moving position. It performs presser operation.

In addition to using an inclined cam as the operating means for changing the vertical position of the presser, for example, a slider mechanism may be provided on the presser device side, and an actuating piece that abuts against the slider may be provided at the reciprocating end of the carriage. Although there are means for converting the vertical position of the presser by moving a slider, the conventionally known converting means described above is extremely troublesome to operate when a plurality of presser apparatuses are arranged side by side. In the present invention, when two or more sets of presser devices are arranged side by side, the device for converting the vertical position of the presser in the presser devices located at the ends of the side-by-side arrangement is operated by the above-mentioned conventional means or any other arbitrary means. Since both sets of presser devices adjacent to each other are connected via a swinging lever that is pivotally supported in the middle, the swinging levers are tilted in conjunction with the conversion operation of the presser device at the end position. The conversion operations of the sets are also performed simultaneously.

〔Example〕

Embodiments of the device of the present invention will be described with reference to the drawings.

In FIG. 1, 1 is a needle bed, 2 is a knitting carriage, and 3 is a rail piece 4 that is accompanied by the reciprocating movement of the carriage.
On the other hand, the board is moved in a suspended state by a support piece 5, and as shown in FIG. 2, the board is equipped with a plurality of sets (two sets in the illustrated example) of presser devices arranged in parallel.

Each set of presser devices includes a pair of pressers 6a that move up and down with respect to the sinker opening of the needle bed 1;
Holders 7a and 7b each having a presser 6a and 6b attached thereto are inserted into groove pieces 8 attached to the base plate 3 and moved up and down, and the holders 7a and 7b each have a presser 6a and 6b attached thereto, and are moved up and down. Both ends of the rolling piece 9, which has a shaft supported 10 in the middle, are connected to the holders 7a and 7b of each presser by pins 11, and the pins 11 are guided through the elongated holes 8a in the vertical direction of the groove piece 8. By tilting one side of the moving piece 9, when one presser 6a moves upward, the other presser 6b is in the downward movement position, and by tilting the other side of the rolling piece 9, both pressers 6a , 6b were changed in their vertical positions, so that the knitted fabric was pressed by the presser in the downward movement position, and was paused in the upward movement position.

As mentioned above, between the two adjacent presser devices of the plurality of presser devices installed in parallel on the board 3 (if three sets are installed in parallel, between the first and second group, and between the second and third group) (set), the middle is pivoted to the board 3 13
A swinging lever 12 is provided, and both ends of the swinging lever 12 are connected to one presser holder 7a, 7b of the adjacent pair and to a vertically elongated hole 1 provided in the base plate 3.
4 was connected with a pin 15 inserted through it. Reference numeral 16 indicates a stopper that restricts the tilting position of the swing lever 12. It should be noted that the presser holders located at both ends of the multiple sets of presser devices installed in parallel, that is, the third
Presser holder 7 in both end positions shown in the figure
When each of holder 7a and 7b is in the downward movement position, as shown in FIG. By this locking, each set presser is immovably stabilized in its position by the interlocking mechanism of the rolling piece 9 and the swinging lever 12.

Next, the vertical conversion operation of the pressers in each set will be explained.

As shown in FIG. 1, as a conversion actuating device, a slope cam 20 and a lock release piece 2 are installed at both ends of the reciprocating movement of the carriage 2 so that the position can be adjusted according to an arbitrary knitting width.
1 will be provided.

In FIGS. 2 and 3, the carriage 2 moves in the direction of the arrow, and the substrate 3 is moved in the same direction, and when it reaches the end of the movement, the holder 7a of the presser device located at the forefront is The locking claw piece 17 collides with the lock release piece 21, the claw piece 17 is pushed against the spring 18, the lock of the holder 7a is released, and then the frontmost set is rolled. The protruding pin 19 provided at the front end of the piece 9 collides with the slope cam 20 and the protruding pin 19 moves along the slope, so the rolling piece 9 tilts and the lower part connected by the pins 11 at both ends of the protruding pin 19 collides with the slope cam 20. In order to move the holder 7a in the moving position upward and move the other holder 7b downward, this set of pressers 6a, 6b
The vertical position of is converted. Along with this conversion operation, the swinging lever 12, which is connected to the holder 7b that moves downward by a projecting pin 15, tilts, and due to the tilting, the other end of the lever is connected to the end of the lever that moves upward. The holder 7a of the presser device of the next set moved upward, and along with the upward movement, the other holder 7b is moved downward by the tilting of the rolling piece 9 of the set, and the presser device in the downward movement position is moved upward. 6b is its holder 7b
is fixed by the claw piece 17, and thus the vertical position of the presser in each set is changed, and the knitting fabric presser is stabilized in the downward position according to the direction change of the carriage 2. It moves in this state, and when it reaches the moving end, the operation sequence in each set is the same as above when it collides with the slope cam 20 and the unlocking piece 21 provided at the moving end. The vertical position of the presser is simultaneously converted.

Thus, in this device, as the pair of pressers in one set of pressers located at the end of the board 3 are arranged in parallel, the vertical position of the other pair of pressers is changed via the swing lever 12. Position conversion operations can be performed simultaneously.

〔Effect of the invention〕

According to the present invention, in a device equipped with a plurality of sets of presser devices in which a pair of pressers are moved up and down alternately, the vertical movement of the presser of the presser device located at the end of the parallel arrangement can be arbitrarily and appropriately converted. Although it is converted by an actuating device, it is possible to simultaneously convert other sets of pressers installed in parallel in conjunction with the vertical movement conversion operation. The structure is extremely simple and the operation is accurate because the presser devices are connected only by connecting the pressers with the presser. This requires a considerable amount of movement of the carriage, but
In the present invention, it is only necessary to move one set of end pressers up and down, so the amount of movement of the carriage is the same as in the case of one set of pressers in the past, and by moving the slider, each set of pressers can be moved up and down. A device that changes the position has a significantly complicated operating structure and is troublesome to maintain and maintain, but the present invention has the effect of eliminating these disadvantages.
