Description

[Detailed description of the invention] (Industrial application field) This invention is an actuation device for a row count in a knitting machine,
Specifically, the present invention relates to an actuating device for a tier counter (hereinafter also referred to as an actuated body) that counts the number of courses of knitted stitches.

(Prior Art) As an operating device for a row counter in a conventional knitting machine, there is one described, for example, in Japanese Patent Publication No. 39-4024.

The operating device of the stage counter disclosed in this publication is
Based on the reciprocating movement of the carriage of the knitting machine, the connecting piece of the row counter (leg 26b in the same publication) is rotated by a protruding piece on the carriage side (lever 20 in the same publication), thereby counting. I was beginning to fulfill my role.
That is, depending on the number of times that the protruding piece on the carriage side collides with the communication piece each time it reciprocates and swings the cam, the counting operation of the stage counter is activated as once for one way and twice for reciprocating. (hereinafter referred to as counting operation).

(Problem to be solved by the invention) However, in the above-mentioned conventional device, unless the protruding piece on the carriage side collides with the connecting piece of the actuating device during the reciprocating movement of the carriage, the stage counter will not count. No action is taken. Therefore, if the carriage is reciprocated and knitting is performed at a point where the protruding piece on the carriage side does not collide with the connecting piece of the actuating device, the number of knittings (the number of knitting courses) due to the reciprocating movement is counted as the number of stages. There was a problem that it was not possible to count due to

(Means for Solving the Problems) In order to solve the problems in the above-mentioned conventional technology, this invention uses a stage counter that performs counting operations by one reciprocating movement of the power intake part to organize the carriage of the knitting machine. The actuating device for a row counter in a knitting machine for counting the number of runs consists of an endless belt with internal teeth, which is stretched between a pair of left and right guide wheels, and is driven by the drive source of the carriage through the guide wheels. A motion belt (also referred to as a motion member) that rotates in forward and reverse directions, a machine frame installed adjacent to the motion belt, a connecting portion that engages with the power intake portion of the stage counter at one end, and the other. a rotating lever having a substantially L-shape with a mounting portion at an end, and whose center portion is rotatably supported by a support shaft substantially perpendicular to the direction of movement of the linear portion of the movement belt with respect to the machine frame; and a rotation lever rotatably supported by a mounting pin substantially parallel to the spindle at the mounting portion of the rotation lever, and having an open end abutting an internal tooth of one linear portion of the movement belt. a return spring that biases the pivot lever in one direction of rotation so that the open end of the pivot piece is always brought into contact with the internal teeth of one straight section of the motion belt; and a neutral spring that elastically holds the rotating piece at an intermediate rotating position where a straight line connecting the open end of the rotating piece and the mounting pin is substantially perpendicular to one straight line portion of the movement belt.

(Function) In the above-described means, when the direction of movement of the carriage of the knitting machine is changed by the drive source, the direction of movement of the movement belt is also changed.

During this conversion of the moving belt, the open end of the rotating piece meshes with the internal teeth of the moving belt, and as the belt rotates, the rotating piece is rotated about the attachment pin. As this rotating piece rotates, the rotating lever is rotated around the support shaft against the elasticity of the return spring, and the power intake part of the stage counter is operated, so that the stage counter is started to count. Ru.

Thereafter, when the rotary piece exceeds the neutral rotation position, the open end of the rotary piece resists the elasticity of the neutral spring and rides over the internal teeth of the movement belt, allowing the belt to rotate. At the same time, the pivot lever is returned to its original state by the elasticity of the return spring.

Therefore, no matter where the reciprocating direction of the carriage is changed by the power source of the knitting machine,
A stage counter is activated in conjunction with the direction change, and the number of formations (the number of formation courses) can be counted.

(Example) An example of this invention will be described below with reference to the drawings. Fig. 1 schematically shows the actuating device of the actuated body stage counter; Fig. 2 shows an enlarged view of the main parts; and -
In FIG. 3 showing a cross-sectional view taken along the line, and FIG. 4 showing a cross-sectional view taken along the line - in FIG. 2, the upper piece 1a and the lower piece 1b
A pair of left and right guide wheels 2 and 3 are arranged in a spaced apart state on a long machine frame 1 having a U-shaped cross section. One of the guide wheels 2 and 3
The shaft 4 is rotatably supported by the machine frame 1, and the coaxial shaft 4 is appropriately connected to a drive source (not shown) such as a motor via a power transmission mechanism such as a gear mechanism or a chain mechanism. , the guide wheel 2 is rotated in forward and reverse directions by the same drive source. Further, the other guide wheel 3 is rotatably supported on the machine frame 1 by a shaft 5. Note that outer teeth 2a and 3a are formed on the outer peripheries of both guide rings 2 and 3, respectively.

A movement belt 6, which is a movement member, is hung around both guide wheels 2 and 3. exercise belt 6
consists of an endless belt having internal teeth 6a, which mesh with external teeth 2a, 3a of both guide wheels 2, 3.

A guide member 7 is fixed to the left end of the machine frame 1 with bolts or the like. The lower surface of the horizontal portion 7a formed on the guide member 7 is in contact with the upper straight portion of the exercise belt 6.

On the upper piece 1a of the machine frame 1, a stage counter 8, which is an actuated body, is installed substantially above the guide member 7. Note that the stage counter 8 in this example is one that can count hundreds of digits by adding or subtracting, for example, a stage counter similar to the one described in Japanese Utility Model Publication No. 10740/1974. .

Since the stage count 8 is well known, a detailed explanation thereof will be omitted, and an outline will be described below with reference to FIG. 5. On the substrate 80, dial shafts 81 to 81 for one digit, ten digit, and hundred digit are rotatably supported. Each dial shaft 81-81 has a dial 82 and a feed gear 83, respectively. Further, a slide plate 84 disposed so as to be slidable in the left-right direction along the substrate 80 is always urged to the right by a return spring 85 interposed between the slide plate 84 and the substrate 80. On the slide plate 84, an actuation arm 86 having feed pawls 87-87 that can be engaged with each of the feed gears 83-83 of the dial shafts 81-81 is rotatably supported on a shaft 88. The actuation arm 86 is urged toward the dial shafts 81 to 81 by a torque spring 89 interposed between it and the slide plate 84.

The slide plate 84 is a return spring 85
When the actuating arm 86 is slid to the left against the elasticity (the state shown in FIG. 5), the feed pawl 87 of the actuating arm 86 engages with the feed gear 83 of the required dial shaft 81.
rotates the corresponding dial shaft 81 by one tooth. When the slide plate 84 is returned to the right by the return spring 85, the actuating arm 86 operates idle and each feed pawl 87 engages with the next tooth of the feed gear 83, so that the integration or It is possible to perform subtraction counting.

At the right end of the slide plate 84 of the stage counter 8, an interlocking pin 9, which is a power intake part, projects in a hanging shape. By moving this interlocking pin 9 to the left, the stage number counter 8 is operated to count by one scale. Interlocking pin 9
The tip (lower end) is inserted into the machine frame 1 through the long hole 10 of the base plate 80 and the long hole 11 of the upper piece 1a of the machine frame 1, and is located to the right of the guide member 7.

At the lower position of the interlocking pin 9, the center portion of the approximately L-shaped rotating lever 12 is attached to the support shaft 13 on the machine frame 1.
It is rotatably supported. That is, the intermediate portion of the rotary lever 12 is rotatably supported around an axis in a direction substantially orthogonal to the movement direction (left-right direction) of the exercise belt 6.

The tip of one end of the rotating lever 12 extending upward is bent toward the front as a connecting portion 14, and an engagement hole 15 formed in the connecting portion 14 is engaged with the interlocking pin 9.

The other end of the pivot lever 12 is formed as a mounting portion 16 extending leftward, and a pivot piece 17 is rotatably supported at the tip of the mounting portion 16 by a mounting pin 18 . That is, the rotating piece 17 is pivotably supported around an axis parallel to the axis of the rotating lever 12.

A locking piece 19 is bent at the lower end of the rotating piece 17, and a neutral spring 20 is interposed between the locking piece 19 and the support shaft 13. The neutral spring 20 biases the rotating piece 17 to an intermediate rotating position (see the two-dot chain line in FIG. 5), which is normally vertical. In other words, the rotating piece 17 is springed toward an intermediate rotating position where a straight line L connecting the axis of the mounting pin 18 and the open end (upper end) 21 is approximately perpendicular to the straight line portion of the movement belt 6. , neutral spring 20
is starting to come into play.

The open end 21 of the rotating piece 17 is bent toward the front, and the open end 21 is brought into contact with the internal teeth 6a of the upper straight portion of the movement belt 6.

In the above-mentioned actuating device, when the movement belt 6 is rotated (forward rotation) in the clockwise direction (see the arrow in FIG. 2), as shown in FIG.
The rotating piece 17 is tilted to the right about the mounting pin 18 against the elasticity of the neutral spring 20, and the rotating piece 17 is urged counterclockwise by the elasticity of the neutral spring 20. In this state, the open end 21 of the rotating piece 17 is in contact with the inner tooth 6a on the upper straight portion of the movement belt 6. At this time, rotating piece 1
The open end 21 of 7 allows the belt 6 to rotate while successively overcoming the internal teeth 6a of the rotating movement belt 6.

Then, when the rotation of the movement belt 6 is converted, that is, from the normal rotation to the reverse rotation,
During the conversion, the open end 21 of the rotating piece 17 meshes with the internal teeth 6a of the movement belt 6, and the rotation of the belt 6 causes the rotating piece 17 to rotate counterclockwise around the mounting pin 18. be done. At this time, since the exercise belt 6 is guided by the horizontal portion 7a of the guide member 7, the rotation lever 12 is rotated counterclockwise along with the rotation of the rotation piece 17. By this rotation of the rotation lever 12, the interlocking pin 9 is moved to the left, and the total number of stages is 8.
is activated to count one division.

Thereafter, when the rotating piece 17 exceeds the neutral rotating position (see the two-dot chain line in FIG. 2) and is tilted to the left around the mounting pin 18, the rotating piece 17
is in a state of being biased clockwise by the elasticity of the neutral spring 20, and the distal end portion 21 of the rotating piece 17
is the internal tooth 6a in the upper straight portion of the movement belt 6.
(See Figure 6). At this time as well, the open end 21 of the rotary piece 17 successively overcomes the internal teeth 6a of the rotating movement belt 6, and
rotation is allowed. Further, the slide plate 84 of the total number of stages 8 is returned to its original state by the elasticity of the return spring 85, and at the same time, the rotating lever 12 is returned to its original state.

Further, the rotation of the exercise belt 6 is converted.
That is, when the reverse rotation is converted to normal rotation, the open end 2 of the rotating piece 17
1 meshes with the internal teeth 6a of the movement belt 6, and due to the rotation of the belt 6, the rotating piece 17 engages with the mounting pin 1.
It is rotated clockwise around 8. At this time as well, since the exercise belt 6 is guided by the horizontal portion 7a of the guide member 7, the rotation lever 12 is rotated counterclockwise along with the rotation of the rotation piece 17. . Therefore, as the rotary lever 12 is rotated, the interlocking pin 9 is moved to the left, thereby causing the stage number counter 8 to count by one scale.

Thereafter, when the rotating piece 17 exceeds the neutral rotating position (see the two-dot chain line in FIG. 6) and is tilted to the right around the mounting pin 18, the above-mentioned second
When the state shown in the figure is reached, the slide plate 8 of the number of steps 8
4 and the rotating lever 12 are returned to their original states by the elasticity of the return spring 85 as described above.

As described above, when the movement direction of the movement belt 6 is changed, the rotation piece 17 is rotated by the movement of the movement belt 6 immediately after the change, and the rotation lever 12 is rotated in conjunction with the movement of the movement belt 6. Therefore, the counting operation of the stage number counter 8 is accomplished.

The above-described actuating device counts the number of knitting courses (knitting times) by being installed in a knitting machine A as shown in FIG. 7, for example. This knitting machine A
The knitting machine main body 23 on the table 22 is equipped with a carriage 24 that moves back and forth, and the knitting machine main body 23 is equipped with a carriage 24 that moves back and forth.
3 to the carriage drive device 26 via the stand 25.
is supported. The carriage drive device 26 includes a drive pulley 27 and a driven pulley 28 supported by a stand 25, a drive motor 29 that drives the drive pulley 27, a drive belt 30 hooked around both pulleys 27 and 28, and the drive belt. a coupling body 31 attached to 30 and connected to said carriage 24;
The knitting is accomplished by reciprocating the carriage 24 as the drive belt 30 is rotated forward and backward by the drive of the drive motor 29. Drive motor 29 of this knitting machine A
The guide wheels 2 on the driving side of the actuating device are linked via a suitable power transmission mechanism such as a gear mechanism or a belt mechanism so that the guide wheels 2 on the driving side of the actuating device are linked to each other, and the number of knittings due to the direction change of the reciprocating movement of the carriage 24 is is counted by a stage counter. Therefore, no matter where the carriage 24 is reciprocated at any position on the knitting machine main body 23, the number of times the carriage 24 is reciprocated can be properly counted.

Note that since the return spring 85 applies a rotational force in one direction to the rotation lever 12, malfunction (defective return) of the rotation lever 12 can be prevented, and reliable operation can be obtained.

Further, the rotating piece 17 is placed at an intermediate rotating position (see FIGS. 2 and 6
By applying the neutral spring 20 that springs toward the two-dot chain line in the figure, the rotating piece 17
It is possible to prevent malfunctions (defects in return) and ensure reliable operation.

Furthermore, the movement belt 6 is constituted by an endless belt, and the open end of the rotary piece 17 is brought into contact with one straight portion of the endless belt between the guide wheels 2 and 3. With a simple structure in which the open end 21 of the rotating piece 17 is brought into contact with the rotating piece 6, accurate counting operation can be obtained.

(Effect of the invention) In other words, according to the actuating device for the row count in the knitting machine of the present invention, no matter where the reciprocating direction of the carriage is changed by the power source of the knitting machine, the reciprocating motion of the carriage is interlocked with the direction change. The stage counter is activated,
Since the number of knittings (the number of courses of knitting) can be counted, it is possible to prevent malfunctions of the stage counter that occur in conventional devices.

In addition, by bringing the open end of the rotating piece into contact with the internal teeth of the movement belt with the elasticity of a neutral spring,
It is also recognized that accurate counting operation can be obtained with a simple structure.
