Technical field

TECHNICAL FIELD [0001] The present invention relates to an electronic jacquard apparatus and also relates to an electronic jacquard cassette that is used by being mounted on the apparatus.

Background art

A jacquard device is a device provided to control the position of a plurality of yarns hung on a machine base, and performs positioning of a needle for handling each yarn or a plurality of yarns as a group. It is. Here, the needle provided on the machine base is urged in the longitudinal direction in the direction of separating the jacquard device force.

On the other hand, a reciprocating mechanism for reciprocating the jacquard body in the longitudinal direction of the needle is provided with respect to the jacquard body. The relative positional relationship in the longitudinal direction changes. In the positional relationship in which the jacquard body and the needle are both in their original positions, the select hook can be engaged with the needle, and in the engaged state, the needle moves integrally against the urging force according to the movement of the jacquard body, Positioned.

[0003] That is, when the needle is not engaged with the select hook, the needle is held in its original position. When the needle is engaged with the select hook, the jacquard body is By moving, only the needle in the engaged state is moved integrally therewith.

As a result, the position of the needle can be determined according to the attitude of the select hook.

[0004] A so-called electronic jacquard device is being adopted for this type of jacquard device. This electronic jacquard changes the attitude of the select hook based on the curve of the piezoelectric element body, and is versatile by selecting the needle using electronic information for thread positioning. Jacquard can be obtained (Patent Document 1).

[0005] The electronic jacquard employs a so-called cassette type, and selects and operates a certain number of needles (for example, 7 needles). Therefore, a cassette having select hooks corresponding to the number of needles is used as a unit. Consists of many cassettes. Therefore, the number of needles to be positioned On the other hand, it is necessary to have a cassette in which the number is divided by the number of select hooks provided in the cassette.

[0006] In this cassette, there is a fixed hook outside the selenium that is oscillated between an engaging position that engages with the needle and a non-engaging position that is not engaged due to the bending of the actuating body that is the piezoelectric element body force. A number of holding pins are provided that form the swing fulcrum of the select hook. The distal end side of the select hook is an intruding portion of the needle, the proximal end side of the select hook is an actuating body disposing portion where the actuating body is disposed, and further, the bending of the actuating body is further provided. An electronic control unit for operation control is provided.

[0007] Referring to Fig. 7, from the base end side of the cassette (right side in Fig. 7), an electronic control unit 7d provided with an electronic component substrate 10 for controlling the bending motion of the working body, and a piezoelectric on the left side thereof There are provided an actuator body 7c provided with a certain number of actuating bodies 9 which are elemental body forces so as to bend freely, and a hook arrangement part 7b provided with a certain number of select hooks 8 on the left side thereof. The left side (near the tip of the cassette C) is a needle entry portion 7a into which the needle N enters. The needle intrusion portion 7a is provided with a partition wall 11 that defines an intrusion route of each needle N.

By the way, in the electronic jacquard cassette employed in the conventional electronic jacquard device, the cassette body having a rectangular parallelepiped shape is generally a resin molded body, and this cassette body is fixed to the holding plate by bolt connection or the like. In addition, the holding plate was fixed to the reciprocating jacquard body.

On the other hand, as a structure inside the cassette, the holding pin that forms the swing fulcrum with respect to the selector hook has been provided as a holding pin by providing a protruding portion on a cylinder in a part of the cassette body. Therefore, this holding pin is integrated with the cassette.

Disclosure of the invention

Problems to be solved by the invention

[0008] The jacquard device is used for positioning a large number of needles provided in a river race machine, a loom, or the like, and determining a product handle or the like. Therefore, in this device, it is necessary to be able to perform the selection hook selection operation continuously and accurately.

In particular, the select hook engages the needle against the urging force of the needle in the engaged state. Since it pulls to a predetermined position, it must be fastened to the cassette body of the select hook, and to the jacquard body.

[0009] However, in the conventional electronic jacquard, the selection hook is supported by a holding pin provided upright on the cassette body, and the holding pin is the same as the cassette body. Since the material is made of resin, cracks and the like occur at the root portion of the holding pin, and the original function as a support pin cannot be exhibited.

[0010] Further, regarding the tip shape of the select hook, since the tip surface of the conventional select hook is a surface orthogonal to the longitudinal direction of the needle, the tip of the needle is in contact with the tip of the select hook. It was supposed to be an operation that hinders the swing of the select hook.

The object of the present invention has been made in view of the above problems, and the object of the present invention is to enable stable needle selection operation over a long period of time in an electronic jack guard device. The present invention is to provide an electronic jacquard device and an electronic jacquard cassette that can ensure stable operation of the select hook even when the tip hits the tip of the select hook.

Means for solving the problem

[0012] According to the present invention for achieving the above object, the actuator swings between an engagement posture engaging with a needle and a non-engagement posture not engaging due to the bending of the working body also having a piezoelectric element body force. And a holding plate for holding the plurality of cassettes side by side, and a holding plate for fixing and holding the plurality of cassettes side by side. The electronic jacquard device having a reciprocating mechanism for reciprocally moving the jacquard body in the longitudinal direction of the needle is provided. In addition to being configured as a body, the holding pin is supported from the holding plate.

In this electronic jacquard apparatus, the holding pin that holds the select hook is conventionally supported by a holding plate that holds and fixes the cassette body and is fixed and held by the jacquard body that reciprocates in a predetermined direction. The As a result, the select hook is The swing fulcrum is formed in a state of being directly supported from the holding plate. Since the holding pin is separate from the cassette body, the holding pin itself can be made strong and strong.

Therefore, in the electronic jacquard device, a stable needle selection operation can be secured for a long time.

[0014] Further, in the above configuration, the holding plate is positioned on one side in the thickness direction of the cassette body, a cover plate is provided on the other side in the thickness direction of the cassette body, and the holding pins are used as the holding plate. It is preferable to adopt a structure that is supported from both the cover plate and the cover plate.

[0015] By adopting such a configuration, the holding pin can be supported by the holding plate and the cover plate on both side forces in the cassette thickness direction, and the holding pin can be accurately positioned. In addition, a more robust structure can be obtained.

[0016] Now, with regard to the shape and configuration of the select hook, the select hook is brought into the non-engagement posture side in the contact state where the needle is in contact with the select hook at the tip of the select hook. It is preferable to provide an inclined guide.

In this way, by providing an inclined guide at the tip of the select hook, the jacquard body moves to the needle side, and the select hook is disengaged while the tip of the select hook is in contact with the tip of the needle. It is possible to swing to the posture side, and a stable swinging operation can be secured.

[0017] Further, a hook-side stopper that comes into contact with the cassette main body in the non-engaged position on the surface that is on the front side of the select hook at the tip of the select hook when swung from the engaged position to the non-engaged position. It is preferable that a cassette-side stopper portion is provided that stops a further swing of the select hook by contacting a part of the hook-side stopper in the disengaged posture.

In this configuration, the swing of the select hook is stopped by the contact of both stopper portions, and the non-engagement posture of the select hook can be determined in relation to the cassette body.

Therefore, not only the engagement with the needle but also the non-engagement posture of the select hook can be ensured, and the stable operation of the select hook, and hence the needle selection operation can be performed. . [0018] Further, the needle is provided with an engagement hole into which a hook portion provided at the distal end of the select hook enters and engages, and the proximal end side of the engagement hole is brought into contact with the select hook, It is preferable to provide a disengagement guide portion for guiding the select hook from the engaged posture to the non-engaged posture.

In the jacquard device, with the select hook engaged with the needle, the jacquard body reciprocates in the longitudinal direction of the needle, and the needle biased in a specific direction is used as the biasing force. On the contrary, it pulls.

At this time, the hook portion provided at the tip of the select hook engages with the surface on the jacquard body side, which is the tip side, in the engagement hole provided in the needle.

[0020] Now, when the select hook further moves to the proximal end side of the needle, a state occurs in which the distal end of the select hook comes into contact with the release guide portion provided on the proximal end side of the needle. In relation, when the select hook and the needle come into contact with each other, the disengagement guide unit according to the present application guides the select hook to the engagement posture force non-engagement posture.

As a result, the engagement and disengagement of the select hook can be performed reliably and easily, and a stable operation can be ensured.

BEST MODE FOR CARRYING OUT THE INVENTION

[0021] Hereinafter, an example in which the electronic jacquard device including a number of electronic jacquard cassettes C according to the present application is used for positioning control of the bottom bar BB of the river racer R will be described.

In the description, first, the construction of the river racing machine R and the outline of its operation will be described with reference to FIGS.

[0022] River racing machine

Fig. 1 shows the schematic configuration of the river race machine R, and Fig. 1 shows the river race machine R with its diagonal front force.

River lace machine R guides beam warp yarn w wound around multiple beams Bm from the lower part of the machine base to the knitting part via sley S, and entangles beam warp yarn w and bobbin yarn B. The lace RL is formed, and the formed lace RL is alternately lifted and held by the back point bar BPB and the front point bar (not shown), and at the same time the upper cloth is located. Pull up with a porcupine roller PPR wrapped around.

[0023] The generated river race RL is a take-up roll in contact with the porcupine roller PPR.

The structure is wound around W.

[0024] Now, as shown in Fig. 1, in the river racer R, the bobbin B stored in a state where the bobbin yarn b is wound is swung in the front-rear direction of the river racer R. A swing mechanism (not shown) is provided. The position of this bobbin B is unchanged in the left-right direction of the river race machine R.

[0025] Between the sled S and the swinging position of the bobbin B, the beam warp yarn w is moved in the left-right direction of the reversing machine R, and the bottom bar BB The top bar is equipped with 1 TB. Here, both the bars BB and TB are configured to position the beam warp yarn w in the horizontal direction of the machine base. The relative positional relationship between the beam warp yarn w and the bobbin yarn b is expressed as bobbin B. By changing in relation to the timing of movement in the front-rear direction, a river race RL can be formed.

With reference to FIG. 2, the process of forming the river race RL will be described below.

In the figure, a line (indicated by a one-dot chain line extending in the vertical direction), which is illustrated in parallel in the vertical direction, is a line indicating the bobbin thread b. The beam warp yarn w is positioned by the BB and the top bar TB.

In the river race machine R, the beam warp yarn w is entangled with the bobbin yarn b while moving laterally and moving back and forth, thereby forming a race RL. That is, the position of the beam warp yarn w on the structure is specified by alternately including a laterally moving portion _ww extending in the lateral direction and an arc-shaped knitting advancing portion wh that means movement in the front-rear direction, that is, the progress of knitting. Is done.

In the example shown in FIG. 2, the beam warp yarn w extends from the first lateral movement unit wwl belonging to the previously knitted portion in the progress of knitting to the fourth lateral movement unit ww4 that is subsequently knitted. The bobbin thread b has a back surface position, a front surface position, a back surface position, and a front surface position alternately. Here, in the drawing, the force described and described as fixing the position of the bobbin thread b and moving the beam warp thread w from the front side to the back side is as follows. As shown in Fig. 1, the bobbin thread b repeats its position movement in the front-rear direction with respect to the beam warp thread w at a fixed position in the front-rear direction of the machine base. The relative positional relationship between the warp yarn w and the bobbin yarn b is determined.

[0028] The above is the force that explains the front-back relationship between the beam warp yarn w and the bobbin yarn b. Hereinafter, the formation of the lateral movement portion ww and the knitting progression portion wh described above will be described.

The relative position on the left side and the relative position on the left side can be taken. On the other hand, the guide hole hb provided in the bottom bar BB is relatively small and can determine the position of the beam warp yarn w.

Accordingly, the position of the beam warp yarn w shown in (a) with respect to the bobbin yarn b is shown by the yarn w being positioned at the relative position on the left side of the central guide hole ht provided in the top bar TB. The position relative to the rightmost bobbin thread b 1 is determined.

[0030] In the following, as the knitting progresses, the top bar TB moves to the left by two pitches, and simultaneously the bottom bar BB moves to the left by the same amount. The position of the beam warp yarn w is determined. That is, the lateral movement part wwl is formed. After this process, the bobbin yarn b moves in the longitudinal direction of the machine, and the beam warp yarn w is positioned in front of the bobbin yarn b. The bobbin yarn b is entangled with the beam warp yarn w. It becomes a state. This state is the state shown in (b), and the knitting progression part wh described above is thus formed.

[0031] Subsequent knitting involves the lateral movement related to the top bar TB and the bottom bar BB (formation of the lateral movement part ww2 shown in (c)), and the back-and-forth movement of the bobbin yarn b at each stage (from (c)) By changing the state to (d) and the state change from (d) to (e)), a river race structure can be formed.

[0032] Figure 3 shows the relative positional relationship between the top bar TB and the bottom bar BB in the river race machine R. Is schematically shown.

These top bar TB and bottom bar BB are each configured to move in the left-right direction of the machine base.For example, the top bar TB can take 33 positions from 0 to 32. The bottom bar BB can take two positions, 0 and 1. The positioning of these bars TB and BB in the left-right direction is executed by the jacquard devices g [t and Jb individually provided for the respective bars TB and BB.

As can be seen from the drawing, a case is shown in which the non-engaging posture and the engaging posture are alternately taken in order from the upper hook 8 on the upper side.

2 Output of knitting data

In the state shown in FIG. 9 (b), the knitting data for each actuating body 9 is output from the motion control device (not shown) provided for the electronic jacquard gib. Specifically, the knitting data is information that causes the individual actuating body 9 to oscillate in either engaged or disengaged state. On the other hand, the state where the engagement / disengagement of the select hook 8 is reversed is shown.

3 Movement of needle and cassette

The state shown in FIG. 10 (c) shows a state in which the needle N has moved to the left in the figure and the cassette has moved to the right from the state shown in FIG. 9 (b). At this time, the needle N engaged with the select hook 8 is moved to the right as the cassette C is moved to the right, and the needle N that is not engaged is moved to the left according to the operation on the river racer RL side.

4 Pattern knitting

The position shown in Fig. 10 (d) is a state where bobbin B moves in the longitudinal direction of the machine base on the river racer RL side, and one unit of knitting is executed.

5 Return to original position

Thereafter, after the state shown in FIG. 11 (e), as shown in FIG. 11 (f), the original position is restored in accordance with the information on the previous pattern knitting.

6 Accepting new knitting data

The state shown in FIG. 12 (g) is the same state as shown in FIG. 9 (b), and the engagement state of the select hook 8 and the needle N is switched according to the newly sent knitting data. Thereafter, the operation after FIG. 10 (c) is repeated, and the knitting proceeds.
