Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer needle and a transfer jack in a flat knitting machine.

[0002]

2. Description of the Related Art A general flat knitting machine has a needle bed in which knitting needles are slidably accommodated and the heads thereof are arranged to face each other in an inverted V shape in a side view. Then, for example, it is impossible to reduce the inside of both sides such as rubber knitting which is knitted using front and back knitting needles.

In order to address these problems, first, as described in Japanese Patent Publication No. 4-7907, a needle bed in which knitting needles are slidably accommodated is
A transfer jack bed, which is arranged in an inverted V shape in the side surface shape and accommodates a transfer jack in a jack groove so as to be capable of advancing and retreating, is provided above each needle bed, and the stitch to be transferred is transferred from the knitting needle to the transfer jack, and the stitch is engaged. There is a flat knitting machine having a transfer device for moving the stopped transfer jack in the lateral direction and then transferring the stitch of the transfer jack to a desired knitting needle for transferring the stitch.

Further, as disclosed in Japanese Patent Application Laid-Open No. 1-168943, a transfer jack, which supports a transfer jack bed above a needle bed via a support member and has a stitch engaging portion at its tip, is transferred. The transfer jack is slidably housed in the jack bed, and the transfer jack that accompanies the carriage is moved forward and backward, and the drive means formed on one side of the transfer jack bed is driven to laterally move the transfer jack bed. There is a flat knitting machine having a transfer device which is capable of transferring the stitches locked by the stitch locking portion of the transfer jack in the lateral direction and then transferring the stitches to a predetermined knitting needle.

In addition, as described in Japanese Patent Publication No. 1-57173 previously proposed by the present applicant, a pair of front and rear needle beds provided with slidable knitting needles in a needle groove are provided. A so-called "four-bed" is formed, and the stitches are transferred in the lateral direction by adjusting the knitting needles of each needle bed to transfer the stitches and moving the stitches in the lateral direction. There is also a flat knitting machine that has a transfer device made possible.

Further, as described in Japanese Patent Application Laid-Open No. 63-256752 and Japanese Patent Publication No. 56-21854 previously proposed by the present applicant, a transfer jack is reciprocated in a jack groove above a needle bed. A transfer bed that can be stored is provided, the stitches to be transferred are transferred from the knitting needle to the transfer jack, the transfer jack that holds the stitch is moved laterally, and then the stitches of the transfer jack are transferred to the knitting needle to which the stitch is transferred. There is known a flat knitting machine or the like which has a transfer device for transferring and transferring.

By the way, in the flat knitting machine having the transfer device described in each of the above publications, the transfer jack of the transfer device is used to drive the transfer jack forward / backward, or when the knitting needles are adjusted forward / backward by the cam group of the carriage. A sliding member such as a knitting needle or a knitting needle is likely to excessively move due to its inertial force, which makes it impossible to perform an accurate forward / backward operation of the transfer jack or the knitting needle.

Therefore, for example, in order to impart sliding resistance to the knitting needle and prevent excessive movement, conventionally, a part of the needle body of the knitting needle is thinned by milling or the like, and the thinned portion is bent and elastic force is applied. The one side portion of the knitting needle main body is pressed against the side surface of the needle groove to provide sliding resistance, or another member for providing sliding resistance is provided in the knitting needle main body.

[0009]

However, when a part of the main body is thinned by milling or the like in order to impart sliding resistance to a sliding member such as a knitting needle or a transfer jack by the above-mentioned conventional method, It is difficult to keep the thickness of the wall constant, and if there is variation in the wall thickness, the elastic force formed by bending this part will not be uniform, and it will be possible to make the sliding resistance of the knitting needle, transfer jack, etc. uniform. There was a problem that I could not do it.

When the sliding resistance becomes non-uniform, the traveling speed of the carriage and the auxiliary cam is increased in order to improve the productivity of the knitted fabric, and the moving amount of the sliding member is increased when the advancing / retreating speed of the knitting needle or the transfer jack is increased. There was a problem that variations could occur and accurate knitting could not be performed. In addition, in the case where a part of the main body of the sliding member is made thin by milling or the like to give sliding resistance, a machining process such as milling is required in addition to the process of transferring the function to the knitting needle and mounting the functional component. As a result, there was a problem that productivity was low.

Further, in the case where the knitting needle main body is provided with a separate member for imparting sliding resistance, not only the processing of the separate member and the assembling step for mounting the separate member are required, but also the structure becomes complicated and the productivity is increased. There is also the problem that it will become even lower. The present invention has been proposed in view of the above problems, and a sliding member that can make the sliding resistance of a sliding member such as a knitting needle or a transfer jack uniform with a simple structure and thus improve the productivity of a knitted fabric is inexpensive. The purpose is to be able to provide.

[0012]

In order to achieve the above object, a transfer knitting needle in a flat knitting machine according to the present invention is a transfer knitting needle in a flat knitting machine housed in a needle groove. A stitch expansion portion is formed on the tip side portion of the elastic plate member attached to one side portion of the main body, and a part of the proximal end side of the elastic plate material is extended to form an elasticity imparting portion, and the elastic force of the elasticity imparting portion is formed. By pressing the side surface of the knitting needle main body against the side surface portion of the needle groove, sliding resistance is imparted when the knitting needle is moved forward and backward.

The transfer jack in the flat knitting machine according to the present invention is a transfer jack for transfer in a flat knitting machine in which a stitch locking portion is formed at the tip of the jack body, and at least one of the stitch locking portions is provided. The transfer jack is formed by a plate-shaped elastic plate member, a part of the elastic plate member is overhanged to form an elasticity imparting portion, and the side surface of the jack body is pressed against the side surface portion of the jack groove by the elastic force of the elasticity imparting portion. It is characterized in that it is configured to give a sliding resistance when it is operated to move forward and backward.

Further, the transfer jack may be formed by adhering the main body portion in a state where at least two plate-like elastic plate materials are overlapped with each other, or the projecting portion of the elastic plate material is thin and narrow. One of the features is that the elastic constant of the elasticity imparting portion is set in the plate-shaped portion.

[0015]

When the carriage is reciprocated over the knitting needles of a predetermined width of the needle bed, the knitting needles (sliding members) are moved forward and backward by the carriage to knit a desired knitted fabric of a predetermined width and knitted. When the width is reduced by inward reduction, the transfer jack (sliding member) is moved forward and backward by the transfer cam of the transfer device along with the lateral movement of the transfer jack bed.

When the knitting needle moves forward and backward during knitting of this knitted fabric and when the transfer jack moves forward and backward during transfer,
The main body of the sliding member is pressed by the elastic force of the elasticity imparting portion of the spring plate member fixed to the side surface of the sliding member against the side surface of the groove that accommodates it, and the thickness of the spring plate member is constant. Yes, because it can be easily overhanged,
The sliding resistance can be kept constant.

Further, in the case where the elastic member is a thin plate having a narrow width, the sliding resistance can be finely adjusted by adjusting the sliding resistance and the plate thickness and width.
As a result, excessive sliding back and forth of the sliding member can be prevented.

The selected needle butt 40 of the transfer jack 29B is further pushed a little further in the cam groove 43 of the cam plate 44. The selected needle butt 40 is pushed forward as shown in FIG. This is for clearing the closed latch 55 portion when the knitting needle 3A retracts.

When the front knitting needle 3A is at the position D with respect to the cam group of the carriage 2A, the stitch cam 23 is moved to the jack 1
The butt 15B of No. 2 has passed, and as shown in FIG. 22 [4], the stitch 52 which has been locked to the front knitting needle 3A in FIG. 22 [1].
Is in a state of being received by the stitch locking portion 32 at the tip of the transfer jack 29B that has advanced to the tooth gap portion. Then, when the cam group of the carriage 2A passes through the knitted fabric knitting portion, the transfer jack 29B is held in a state in which the stitch 52 is received by the stitch locking portion 32 at the tip thereof.

Next, the motor 66 of the drive means 69 is driven to rotate the drive screw shaft 67 in a state where the stitch 52 is locked to the stitch locking portion 32 at the tip of the transfer jack 29B that has advanced to the needle bed gap. Then, the transfer jack bed 27B is moved laterally by a predetermined pitch (for example, one pitch) via the slider 68 and the support movement operation bracket 71. Since the gouging portion 79 formed near the main body of the stitch engaging portion 31 at the tip of the transfer jack 29B is located above the protrusion of the sinker or the like, even if the transfer jack bed 27B is moved laterally. , The transfer jack bed 27B can be moved laterally without interfering with the sinkers and the knitting needles 3A and 3B. But they can.

After that, when the carriages 2A and 2B are turned over on the needle beds 4A and 4B at predetermined positions, the butt 15A and 15B of the jack 12 of the knitting needle 3 and the select jack 13 are operated in the opposite manner to the above. , 16 are designated by reference numerals E, F, and F in the cam group of the carriage 2 as shown in FIG.
As shown by G and H, the vehicle passes from right to left. That is, when the front knitting needle 3A on which the stitch 52 is transferred becomes the position from E to F with respect to the cam group of the carriage 2, FIG.
As shown in [1] and FIG. 24 [2], the butt 15B of the jack 12 is operated by the transfer receiving cam 21, the front knitting needle 3A to be delivered advances, and the hook 10 thereof enters the stitch engaging portion 32. The stitch 52 is penetrated and the stitch 52 is engaged with the hook 10.

When the front knitting needle 3A to which the stitch 52 is transferred reaches the position G with respect to the cam group of the carriage 2, the front knitting needle 3A to be transferred by the transfer lasing cam 20 gradually descends, and at the same time. 24. The selected needle butt 40 of the transfer jack 29B is operated by the cam groove 43 of the cam plate 44, the transfer jack 29B is pushed down, and starts descending.
As shown in [3], the stitch 52 held on the stitch holding portion 32 is transferred to the hook 10 of the front knitting needle 3A.
Move on to.

When the front knitting needle 3A on which the stitch 52 is transferred reaches the position H with respect to the cam group of the carriage 2A, the selected needle butt 40 of the transfer jack 29B is lowered in the cam groove 43 of the cam plate 44 to transfer the transfer jack. As 29B further descends, the front knitting needle 3A that has passed the stitch 52 descends, and the transfer is completed as shown in FIG. 24 [4].

When the transfer jack 29B is slid forward and backward by the transfer cam 31 at the time of this transfer, the transfer jack 29B is moved by the elastic force of the elasticity imparting portion 37 of the spring plate material fixed to the side surface of the transfer jack 29B. Side portion 7 of the jack groove 72 for housing

As described above, the sliding member for transferring stitches in the flat knitting machine according to the present invention, when knitting the knitted fabric,
When the carriage is reciprocated between knitting needles of a specified width and the knitting needle is moved by the carriage and the transfer jack is moved forward and backward by the cam, it is fixed to the side surface of the main body of the sliding member such as the transfer jack or knitting needle. Since the elastic force of the elasticity imparting portion of the spring plate material is pressed against the side surface portion of the groove accommodating the elastic plate material with a constant pressing force, the sliding resistance of the sliding member can be kept constant. .

As a result, there is an advantage that the sliding member is free from excess and deficiency of sliding due to inertia, and accurate forward / backward operation can be performed. Further, since the sliding resistance of the sliding member can be kept constant, the traveling speed of the carriage and the auxiliary cam can be increased, and the productivity of the knitted fabric can be greatly improved.

In addition, since a part of the spring-made plate material forming the transfer function part of the sliding member is projected to form the elasticity imparting part, the part having the transfer function to the knitting needle as in the prior art. In addition to the process of mounting the sliding member, there is an advantage that the milling process can be eliminated and the sliding member can be manufactured at a low cost, as compared with a process that requires a machining process such as milling.

Of course, since a part of the spring-made plate material forming the transfer function part of the sliding member is projected to form the elasticity imparting portion, the sliding member also has a simple structure, and the sliding member has a simple structure. There is also an advantage that the productivity of the moving member can be greatly improved. Further, the sliding member need only have a simple structure in which a spring-made plate material forming an elasticity imparting portion is arranged on the side surface of the main body, and in this respect also, the sliding member can be implemented at a lower cost. There is also an advantage to say.

In addition, since the sliding member can be made weak when the elastic member is a thin plate having a narrow width, for example, a small transfer with a fine gauge which cannot be implemented by the conventional braking device. There is also an advantage that it can be attached to the jack and / or the knitting needle.
