DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a hand knitting machine that knits stitches one by one by moving knitting needles back and forth one by one.

Purpose of the Invention The first object of the present invention is to freely select a motor or manual operation as a drive source for knitting.
It is possible to obtain a drive method according to the stitches to be knitted, and a second object of the present invention is to prevent rotational power from the manual operation from being transmitted to the motor when manual operation is selected. It is an object of the present invention to provide a drive device for a hand knitting machine that allows the manual operation to be performed with light force and does not affect the motor.

Embodiment Hereinafter, an embodiment of a hand knitting machine embodying the present invention will be described based on the drawings. In the hand knitting machine of this embodiment, as shown in FIG. Stitches are sequentially formed on each knitting needle 1 while the machine is stopped. This hand knitting machine is capable of performing flat knitting, rubber knitting, rolled knitting, and binding knitting, and the plain knitting and rubber knitting methods will be explained below with reference to FIGS. 1 and 2. In these FIGS. 1 and 2, it is assumed that the carriage moves in the direction of arrow P (to the right).

First, a plain knitting method will be explained based on 1 to 11 in FIG. In this case, a new stitch is to be formed on the main knitting needle 1 on the needle bed shown third from the top in 1 of FIG. Now, the first
1 in the figure, the main knitting needle 1 is placed in the retracted position, and the cylindrical yarn opening 2 is approximately opposite to the second main knitting needle 1 from the top, which has already finished knitting, and is placed on the lower side at that position. In this state, first, the main knitting needle 1 advances to the flattening position, and the flattening of the old stitch is performed (2 to 4 in FIG. 1). Next, the main knitting needles 1 are moved back a little, and the yarn head 2 is raised so that it is located above the main knitting needles 1 (5 in FIG. 1). after that,
The thread 2 moves to the right by approximately twice the arrangement pitch of the main knitting needles 1, that is, by 2 knitting needle pitches, passes above the third main knitting needle 1, and faces the fourth main knitting needle 1 on the right. do.

Then, the yarn head 2 descends and the knitting yarn T is wrapped between the hook 1a and the latch 1b of the main knitting needle 1 (the first
7 to 10) in the figures, the main knitting needles 1 move back to the knockover position, the old stitches are knocked over, and a new stitch is formed using the knitting yarn T. As shown in 2, 3, 5, and 6 in FIG. Prevent rotation in the direction. Further, as shown at 2 to 4 and 8 to 10 in FIG. 1, the knitted fabric presser 4 moves forward to hold down the knitted fabric when the old stitches run out or are knocked over.

As described above, a new stitch is formed on the third main knitting needle 1. Thereafter, the carriage moves to the right by one knitting needle pitch, and the thread head 2 moves to the left by two knitting needle pitches. Therefore, next, a new stitch can be formed on the fourth main knitting needle 1.

Next, the method of knitting the rubber knit will be explained based on 1 to 11 in FIG. 2. In knitting this rubber stitch, one sub-knitting needle 5 provided in the carriage is used when knitting the front stitch on the main knitting needle 1 selected at the upper position on the handle plate to be described later, and the main knitting needle 5 that is not selected is used. When knitting a back stitch, which is a normal stitch, the sub knitting needles 5 are not used. The thread opening 2, latch control plate 3, and fabric presser 4 move at the same timing as in the case of plain knitting. Now, to specifically explain the method of knitting the surface stitches, as shown in 1 to 3 in Fig. 2, the main knitting needle 1 is
~ 3, the sub-knitting needle 5 moves to the left side, and after the old stitch falls out, the sub-knitting needle 5 rotates to the left side, which is the main knitting needle 1 side, and its hook 5a
is caught on the hook 1a of the main knitting needle 1. Next, the hook 1a of the main knitting needle 1 and the hook 5 of the sub knitting needle 5
In the state where a is caught, the main knitting needle 1 retreats, and the sub knitting needle 5 moves forward, and the old stitch becomes the main knitting needle 1.
It was transferred from the side to the sub-knitting needle 5 (4 in Fig. 2), and the sub-knitting needle 5 moved forward independently, its hook detached from the hook of the main knitting needle 1, rotated to the right, returned to its normal position, and transferred. The old stitches are missing. (5 in Figure 2). The latch 5b of the sub-knitting needle 5 is always urged in the opening direction by a spring (not shown).

Next, the yarn opening 2 moves to the right by two knitting needle pitches, and the sub-knitting needles 5 begin to retreat (6 in FIG. 2). Then, after the yarn head 2 descends and the knitting yarn T is passed over the sub-knitting needle 5, the sub-knitting needle 5 further retreats to the knock-over position, the old stitch is knocked over, and the knitting yarn T is placed on the sub-knitting needle 5. A new table is formed (7 in Figure 2). after that,
After the sub-knitting needles 5 advance again to the flattening position and the flattening of the surface stitches is performed (8 in FIG. 2), it rotates to the left (9 in FIG. 2). And main knitting needle 1
The main knitting needle 1 moves forward with the hook 1a of the sub-knitting needle 5 hooked with the hook 5a of the sub-knitting needle 5, and the sub-knitting needle 5 moves backward, so that the surface stitch is transferred from above the sub-knitting needle 5 to the main knitting needle 1 (Fig. 2). 10), the sub-knitting needle 5 rotates to the right and returns to the normal position, thereby detaching the sub-knitting needle 5 from the main knitting needle 1, and the main knitting needle 1 returns to the retracted position (11 in FIG. 2). In the manner described above, front stitches can be formed on the selected main knitting needles 1. Furthermore, when knitting this rubber knitting, unlike the case of the flat knitting described above, the main knitting needles 1 are stopped approximately in the vicinity of the knitting preparation position when shown at 4 to 9 in FIG. 2. The latch control plate 3 also prevents the sub-knitting needles 5 from rotating in the closing direction of the latch 5b.

As shown in FIG. 1, a notched cam portion 93 is formed in a part of the upper outer surface of the first cam ring 31, and only when this notched cam portion 93 and the contact pin 90c are opposed to each other, The sensing plate 90 is allowed to move downward as shown in FIG. 8, and this timing is when the first cam wheel 31 is positioned between the 0 position and approximately the 2 position, that is, when the drive cam body 30 starts rotating. When the contact pin 90c is not opposed to the notched cam portion 93 but is engaged with the outer peripheral upper surface of the first cam ring 31, the sensing plate 90 is held at the upper position.

As shown in FIGS. 4, 18, and 19, a DC motor 94 is installed and fixed on the substrate 12, and a bevel gear 95 is provided on the motor shaft. As shown in FIG. 19, on a shaft 96 erected on the substrate 12, there is another bevel gear 97 that meshes with the bevel gear 95;
7 and a small-diameter spur gear 98 integral therewith are rotatably supported. Further, a large-diameter spur gear 99 serving as a first rotating body that meshes with the spur gear 98 is rotatably supported at the upper end of the shaft 41 . On the lower surface of the spur gear 99, on the shaft 41 is a small diameter spur gear 100 as a second rotating body.
is supported so as to be rotatable and movable up and down, and as is clear from FIGS. 14 and 15, is urged upward by the spring 46 and is normally connected to the lower surface of the spur gear 99. 1st
As shown in FIGS. 8 and 20, a plurality (four in this embodiment) of connection recesses 99a are formed on the lower surface of the spur gear 99 at an angle of 90 degrees apart, and a plurality of connection recesses 99a are formed on the upper surface of the spur gear 100. The same number of tooth-shaped connecting protrusions 100a are formed at an angle of 90 degrees so as to correspond to the connecting recesses 99a, and the connecting protrusions 100a are connected to the spring 46.
The connecting recess 99a is engaged with the connecting recess 99a by the urging force of the connecting recess 99a. Each of the connecting convex portions 100a has a slope portion 100b on one common side and a vertical surface 10 on the other side.
0c are formed respectively. Then, the large-diameter spur gear 99 is moved in the direction of arrow S in FIG.
When the motor 94 rotates in one direction (counterclockwise in the figure), the vertical surface 100c of the connection protrusion 100a and the connection recess 99a
small diameter spur gear 1 through engagement with the vertical inner surface of
When the small diameter spur gear 100 is rotated in the direction of arrow S while the large diameter spur gear 99 is rotated in the same direction and the large diameter spur gear 99 is stopped (as shown in FIG. ), the spur gear 100 escapes downward against the spring force of the spring 46 due to the action of the slope portion 100b, and the rotation of the small-diameter spur gear 100 is caused by the rotation of the large-diameter spur gear 99. Not communicated.

As shown in FIGS. 4, 10, 11, and 18, a gear portion 101 that meshes with the spur gear 100 is formed on the outer periphery of the second cam ring 51. As shown in FIGS. Also, similarly, Figures 4, 10, and 11
As shown in the figure and FIG. 18, a rotary operation wheel 102 is fixed to the upper surface of the second cam wheel 51, and by rotating the operation wheel 102 with a handle 102a, the entire drive cam body 30 is rotated. Ru. The motor 94 is activated by a switch 103 on the needle bed 10 shown in FIG.

Therefore, when the motor 94 rotates in a predetermined direction, that is, in the direction of arrow T in FIG. 4, the spur gear 99 is rotated in the direction of arrow S in FIG. The spur gear 100 is rotated in the same direction through the meshing relationship between the concave portion 99a and the connecting convex portion 100a, and the drive cam body 30 is rotated in the direction of the arrow Q through the spur gear 100 and the gear portion 101. In addition, the rotation operation wheel 10 is rotated by the handle 102a.
When the driving cam body 30 is rotated in the direction of the arrow Q, which is a predetermined direction, the spur gear 100 is rotated through the meshing relationship with the gear portion 101 on the outer periphery of the second cam ring 51. is rotated in the direction of arrow S, but the rotation is not transmitted to the spur gear 99 because the engagement between the connection recess 99a and the connection projection 100a is intermittently disengaged due to the action of the slope portion 100b of the connection projection 100a. Therefore, the rotation is not transmitted to motor 94.

Next, the operation of the drive device in the hand knitting machine configured as described above will be explained first with respect to flat knitting.

Now, when the carriage 11 is located at the left end of the knitting width, as shown in FIGS. 8 and 15,
The lower cam body 43 on the support shaft 41 is rotatably disposed in one position, the upper cam body 42 is positioned downward, and the driven lever 44 is disposed downward and corresponds to the second outer circumferential cam 40. It is separated from the second outer cam 40 at this position. For this reason, the clue operating body 4
7 is located to the left, and as is clear from 1 in FIG. 1, the yarn opening 2 is located to the left of the main knitting needle 1 on which knitting is to be performed.

In addition, the main needle operating body 26 shown in FIG.
A forward moving force is applied by the spring force of the upper spring 24, and it is stopped at the rear edge of the return position regulating plate 28 and stopped at that position. 1 in preparation position
The butt 1c of the main knitting needle 1 of the book is being held.

Furthermore, at this time, the switching operation lever 68
is placed in the position shown in FIG. 9, the contact pin 90b at the upper end of the sensing plate 90 is removed from the switching operation lever 68, and the sensing plate 90 is in a state where it can be moved downward.

In the case of this flat knitting, punch cards are not used and the handle plate 91 is held in the inoperative position, so the main knitting needles 1 can be moved downward as shown in FIG. The sensing plate 90 is in the lower position, the moving plate 73 cannot move forward, and the switching member 88 is held in the rear position. Therefore, as shown in FIGS. 10 and 12, the main needle operating lever 36 is disposed on the upper side, and the auxiliary needle operating lever 71 is disposed on the lower side.
The contact pin 36a of No. 6 engages with the first main needle drive cam 32, and the contact pin 71a of the sub needle operating lever 71 comes off from the first and second sub needle drive cams 62, 63.

In this state, when the motor 94 is rotated by the switch 103 in the direction of the arrow T in FIGS. 18 and 4, the large diameter spur gear 99 is rotated in the direction of the arrow S in FIG. 20 via the bevel gears 95 and 97. Furthermore, the connection recess 99 of the spur gear 99
a and the connecting convex portion 100a of the small diameter spur gear 100
The small diameter spur gear 10
0 is also rotated in the direction of the arrow S, and the drive cam body 30 is rotated in the direction of the arrow Q through engagement with the gear portion 101.

When the drive cam body 30 is rotated in the direction of arrow Q,
Due to the cam action of the first main needle drive cam 32, the main needle operating lever 36 is rotated from the solid line position in FIG. 8 toward the two-dot chain line position. In this case, the return position regulating plate 2
8 is retracted so as to be out of the movement locus of the main needle actuating body 26, the main needle actuating body 26 is allowed to move forward as the main needle actuating lever 36 rotates, and as shown in 1 to 4 in FIG. Then, the main knitting needles 1 move forward and the old stitches fall out.

Next, the main needle operating lever 36 moves back slightly, and the main knitting needle 1 moves back slightly as shown in 5 in FIG. 1 via the main needle operating body 26, and the notch in the flange portion 58 shown in FIG. The portion 58a is the lowering actuation lever 6
0 contact pin 60a, the spring 61
After the lowering operation lever 60 is rotated upward and the thread head 2 is raised, the second outer peripheral cam 40 on the outer periphery of the first cam ring 31 engages with the driven lever 44, and the driven lever 44 is moved to the position shown by the two-dot chain line. The yarn tip operating body 47 is moved to the right, and the yarn tip 2 is moved to the right by two knitting needle pitches, as shown at 6 in FIG. Then, when the notch 58a comes off the contact pin 60a and engages the lower surface of the flange 58 again, the thread 2
is lowered, and the knitting yarn T is fed in a stretched state between the hook 1a and the latch 1b of the main knitting needle 1.

After that, the contact pin 36a of the main needle operating lever 36
rotates back to the solid line position in Fig. 8, and the main needle operating body 2
6 moves backward. Therefore, the main hand operating lever 36 engages with the slope 28a of the return position regulating plate 28 whose front and rear positions are adjusted by the return position changing dial 16, and the return position regulating plate 28 is moved by the spring force of the spring 27. After being pushed away into the accommodating portion 15c against the force, the spring 24 on the mounting shaft 23 stops the return position regulating plate 28 at its rear edge.

Therefore, as shown at 11 in FIG. 11, the main knitting needles 1 move back, the old stitches are knocked over, and a new stitch is formed on the wrong side.

Then, when knitting is completed for one main knitting needle 1 and one rotation of the drive cam body 30 approaches the end, the carriage 11 is moved rightward by one knitting needle pitch.

In this way, knitting is performed for each knitting needle 1, and when one row of knitting is completed and the carriage 11 is positioned to the right of the knitting width edge, as shown in FIG.
The lower cam body 43 is switched and rotated, and both cam bodies 4
Due to the action of the cam surfaces 42a and 43a of 2 and 43,
The driven lever 44 is moved upward, and the first outer cam 3
Corresponds to 9. Therefore, as is clear from FIG. 7, the stop position of the thread operating body 47 before the start of knitting and the moving direction during knitting are reversed.
The knitting that accompanies the carriage 11 moving to the left can be performed in the same manner as described above.

Next, the knitting of the rubber knit will be explained. For example, when performing so-called 1-stitch rubber knitting, a punch card in which perforated and non-perforated parts are recorded alternately for each knitting needle is set in the knitting machine main body 9, and as the carriage 11 slides, the punch card is Accordingly, the handle plate 91 is brought into a state where it can be operated to each of the active and non-active positions, and the switching operation lever 68 is held in the position shown in FIG. Therefore, the sensing plate 90 is held in a downwardly movable state, and the first auxiliary needle drive cam 62 for rubber knitting is formed over 360 degrees.

In this state, the drive cam body 30 is
By rotating the card in the direction of arrow Q and moving the carriage 11 stepwise to the left or right, front and back stitches are knitted corresponding to the perforated and non-perforated portions of the punch card. . That is, when knitting the main knitting needles 1 corresponding to the non-perforated part of the punch card, the sensing plate 90 moves downward together with the main knitting needles 1 as shown in FIG. 10, and the switching member 88 moves to the rear position as shown in FIG. is maintained. Therefore, as shown in FIG. 10, the main needle actuation lever 36 engages with the first main needle drive cam 32, and the contact pin 71a of the sub needle actuation lever 71 engages with the first and second sub needle drive cams 62, 6
3, and as the drive cam body 30 rotates, the first main needle drive cam 32
Due to the action of the main knitting needles 1, the movements shown in 1 to 11 in FIG.
9, 40 and the notch 58a of the flange portion 58, the yarn opening 2 similarly performs the movements shown in 1 to 11 in FIG. 1, thereby forming a back stitch.

In addition, the main knitting needle 1 corresponding to the perforated part of the punch card
When knitting, as shown in FIG. 11, the main knitting needles 1 cannot be moved downward due to the protrusion 91a of the handle plate 91, so even if the contact pin 90a of the sensing plate 90 opposes the notched cam portion 93, the sensing Plate 90 does not move downward. Therefore, the movable plate 73 can freely move forward, and the switching member 88 is moved forward as shown in FIG. Therefore, as shown in FIG. 11, the main needle actuating lever 36 is disposed at a lower position and its contact pin 36a is connected to the second main needle driving cam 3.
At the same time, the secondary needle actuating lever 71 is placed in the upper position and its contact pin 71a engages with the first secondary needle driving cam 62.

Therefore, the main knitting needle 1 is moved to the second main knitting needle by the cam action of the second main needle drive cam 33 based on the rotation of the drive cam body 30.
Perform the exercises shown in figures 1 to 11. Also, the cam action of the first auxiliary needle drive cam 62 causes the auxiliary needle operating lever 71 to
is rotated from the solid line position in FIG. 9 to the two-dot chain line position, the support body 76 is moved forward via the connecting link 77, and the sub knitting needles 5 move forward as shown in 1 to 3 in FIG. do. Then, one protruding cam 85 on the outer periphery of the second cam ring 51 engages with the operating lever 87, and the rotating lever 80 is rotated to the two-dot chain line position in FIG. 5, as shown in FIG. By moving forward after the sub-knitting needle 5 is hooked on the hook 1a of the main knitting needle 1 with its hook 5a, the stitch is transferred to the sub-knitting needle 5 and the stitch is left out (5 in FIG. 2). after that,
The secondary knitting needles 5 are moved by the cam action of the first secondary needle drive cam 62.
is retreated, the knitting yarn T is supplied onto the hook 5a by the thread opening 2, the old stitch is knocked over, and a new stitch is formed on the front stitch (6, 7 in FIG. 2).
Next, the sub-knitting needles 5 advance to the flattening position by the cam action of the first sub-needle drive cam 62, and then move backward (8 in FIG. 2), and the other protruding cam 85
is engaged with the operating lever 87, the sub-knitting needle 5 is rotated, hooked onto the main knitting needle 1, and moved further backward in that state, thereby transferring the new stitch to the main knitting needle 1 (Fig. 2). 9, 10). Then, the main knitting needle 1 is moved back and a new front stitch is provided on the hook 1a.

As described above, a back stitch is formed on the main knitting needle 1 corresponding to the non-perforated part on the punch card, and a back stitch is formed on the main knitting needle 1 corresponding to the perforated part on the punch card.
For this, a front stitch is formed and rubber knitting is performed by repeating this process.

In this way, when the drive cam body 30 is rotated in the direction of the arrow Q as the motor 94 is rotationally driven,
Due to the cam action of the main needle drive cam and the sub needle drive cam on the drive cam body 30, one main knitting needle 1 or sub knitting needle 5 is operated in the front-rear direction to knit the back stitch or the front stitch. Moreover, since the drive for knitting can be performed by a motor as described above, the labor required for knitting can be significantly reduced, and especially knitting can be performed by continuously moving the carriage 11 as in flat knitting or rubber knitting. The case is extremely efficient.

On the other hand, in order to insert one pattern into flat knitting, it is more convenient to obtain the knitting drive by manual operation. In other words, in such a case, the motor 94 is stopped before the pattern knitting part and the carriage 1 is turned off.
1 is stopped, and the carriage 11 is switched to a state where it can be patterned. Then, in this state, the rotary operation wheel 102
Manually operate the handle 102a of the drive cam body 3.
0 in the direction of arrow Q. in this case,
The rotation of the drive cam body 30 is transmitted through the gear portion 101 to the small diameter spur gear 100 as shown by the arrow S in FIG.
However, due to the sliding action of the slope 100b of the connecting convex portion 100a of the spur gear 100, the rotation is not transmitted to the large-diameter spur gear 99. Therefore, the drive cam body 30 can be rotated with a light force, and the motor 94 is not affected at all. In this way, if the knitting drive is performed manually, the pattern can be knitted at a desired position without any misalignment.

Effects of the Invention As illustrated in the embodiments above, the present invention is aimed at a hand knitting machine in which knitting needles are moved back and forth one by one to knit one stitch at a time. By linking the manual operation member that rotates by manual operation and the motor, and making it possible to drive the rotary drive body selectively between the manual operation member and the motor, it is possible to select a drive method according to the organization. It can be selected arbitrarily and its organization can be efficiently and error-free, providing an excellent effect.

Moreover, this invention provides a connection between the rotary drive body and the motor.
A power contact/separation device is provided that transmits the driving force of the motor to the rotary drive body and interrupts the rotational power so that the rotation power is not transmitted to the motor when the rotary drive body is rotated based on the manual operation member. Therefore, when manually rotating the rotary drive body, the operation can be performed with light force, and there is also an effect that the motor is not affected at all.
