Description

[Detailed Description of the Invention] This invention allows the needles or jacks on the needle bed to be selected and forcibly moved in one direction, front and rear, by a small amount as the carriage slides, thereby accurately dividing the butts into two groups, front and rear. The first aspect of the present invention is to provide a needle selection device for a knitting machine that is capable of sorting needles. In a knitting machine placed in an upper position by means of a springing means, the needle stem of the knitting needle or jack is provided with a protrusion that projects upward separately from the butt, and the butt of the knitting needle or jack is guided to a carriage mounted on the needle bed. A selection member that protrudes into the passage and its guiding passage at appropriate times, and a guide member that controls the movement of the protrusion are provided, and the selection member selectively acts on the bat that is aligned with the sliding of the carriage and guided into the guiding passage. At the same time, the knitting needles or jacks that have only been moved are placed in a downward position against the splashing means, and the protrusions are submerged under the lower surface of the guide member and moved to either the front or rear, and the guide member is moved to the front or rear. A slight positional difference in the front and back direction between the diver and the non-diver is accurately generated, and an accurate needle selection operation is performed based on the positional difference.

In a second invention, in addition to the selection member and the guide member of the first invention, a sensing actuation member connected to the selection member is provided on the carriage, and it is possible to select whether or not the selection member protrudes into the guide path. This invention relates to a needle selection device for a knitting machine in which a sensing and actuating member is responsible for the needle selection.

In both the first and second inventions, the needle selection operation is performed only by sliding the carriage on the needle bed, without using a needle selection function member such as a handle plate provided on the needle bed side as in the past. It has specificity in the point it causes.

1 to 9 show a first embodiment of the present invention.

A needle bed 1 is formed with a front knitting needle planting needle groove 2 and a rear jack planting needle groove 3 aligned in the front and back, and a horizontal rail 4 is fixed between both needle grooves 2 and 3. The knitting needle 6 with the butt 7 protruding from the needle groove 2 is loosely inserted into the lower groove of the support plate 5 of the needle bed 1, and the jack 9 with the butt 10 protruding from the needle groove 3 is passed through the upper groove of the support plate 5, and its tip is inserted. The lower surface of the needle bed 1 is made to collide with the rear side of the butt 7.

The knitting needles 6 and the jack 9 are designed to be able to move up and down at their rear ends with a horizontal position as the upper limit, and are always placed in a horizontally upper position by applying springs 8 and 11 to their lower surfaces, respectively.

A butt 10 and another protrusion 12 are provided at the rear end of the shack 90 needle shaft to project upward, and the upper end thereof is sharpened into a conical shape.

Base plate 1 of carriage 13 slidably mounted on needle bed 1
As shown in detail in FIG. 2, the lower surface of 4 has a first body needle passage 15 through which the jack 90 butt 10 at the rear body needle position passes, a guide passage 16 for the butt 10 advanced from the body position, and a needle bed. A sliding guide 17 that fits into the rail 4 of 1, a second body needle passage 18 through which the knitting needle 60 butt 7 at the body position is passed, and a needle passage X
, y are provided.

The guide passage 16 is enlarged in the front and the middle, and a rear guide passage a is formed between the rear wall 16a of the guide passage 16 and the inside of a reverse pressure angle-shaped introduction cam 20 that protrudes from the front to the rear at both left and right ends. A horizontal cam 21 is provided.

The introduction cam 20, as illustrated on the right side of FIG.
Jack 90 butt 1 advanced from the body position in the needle groove 3
0 to the guide path 16 to guide the rear side guide path a of the rear surface of the horizontal cam 21, and a swingable guide cam 22 is provided at the inner end of the horizontal cam 21.

This guide cam 22 can be flipped up to the position shown by the chain line in FIG. 2 to create an inner entrance of the rear guideway ai.

The bat 10 passes through the guide cam 22 excluding the guide cam 22, and on the other side is guided by the guide cam 22 and passes through the front side of the horizontal cams 21. a cam protrusion 23 protruding from the cam protrusion 23;
and a triangular selection member 24 that slightly protrudes forward the bat 10 that passes in alignment between the horizontal cam 210 and the horizontal cam 210 by moving forward at the appropriate time.

On the front surface of the horizontal cam 21, a recessed portion 25 recessed toward the rear is formed just outside the selection member 24, and an inclined surface 25a inside the recessed portion 25 is formed.
A permanent magnet 26 is installed along the back surface of the recess 25 and an inclined sorting and enlarging cam 27 with a notch 28 provided on the lower surface of the recess 25 is installed between the recess 25 and the inside of the introduction cam 20. When the member 24 does not protrude, the butt 10, which moves along the front surface of the horizontal cam 21, is moved backward along the inclined surface 25a of the recessed part 25 by the magnetic force of the permanent magnet 26, and is moved backward along the notch of the sorting and enlarging cam 27. 28 and escapes outward from the rear side of the introduction cam 20.

When the sorting member 24 is protruding, the butt 10 passing through the front surface of the sorting member 24 is selected by protruding a little forward, and after hitting the front face of the sorting enlargement cam 27 and moving it forward, the bat 10 passing through the front surface of the sorting member 24 is selected. The bat 10 is guided rearward to meet the bat 10 that has passed through the underside of the notch 28, and then the underside of the base plate 14 is allowed to escape.

As shown in detail in FIG. 5, the selection member 24 is formed by bending the rear end of a sliding plate 29 that projects forward along the lower surface of the base plate 14 twice at right angles. At the front end of 29, a sensing actuating member 30 is provided which is formed by bending twice at right angles symmetrically with the selection member 24.

The sliding plate 29 has springs 3 that press backward between it and the base plate 14.
1 is hung, and the selection member 24 inserted into the lower surface from the hole 21a of the horizontal cam 21 is placed in a position hidden behind the lower surface of the horizontal cam 21 as shown on the right side of FIG.
0 protrudes from the front part of the second body needle passage 18 into the passage 18, and is pushed forward by the knitting needle butt 7 passing through the body passage 18, producing the sensing action shown on the left side of FIG. At this time, the selection member 24 is projected to the front of the horizontal cam 21.

The sliding plate 29 is provided with an operating pin 32 that projects upward from the elongated hole of the base plate 14.

When the sensing member 30 protrudes into the second body needle passage 18, it forms a contact surface 3 where three adjacent knitting needle butts 7 that pass through the second body needle passage 18 come into contact with each other.
It has 0a.

The base plate 14 is provided with the above-mentioned cam protrusion 23 and a guide member 33 extending in the transverse direction and protruding from the rear edge of the base plate 14 in correspondence with the rear side of the selection member 24 and the sorting/enlarging cam 27.

This guide member 33 has a lower edge that is inclined slightly forward, and the protrusion 12 of the jack 9 that moves along the front surface of the horizontal cam 21 is shown on the rear side as shown in an enlarged view in FIG. The protrusion 12 of the jack 9, which serves as a member for guiding the jack 9 along the horizontal cam 21 and protrudes forward when the selection member 24 protrudes from the front surface of the horizontal cam 21 as shown on the left in FIG. 2, is shown by the chain line in FIG. It passes through the flow line A that passes under the lower surface of the guide member 33 to the front side.

The downward movement in which the protrusion 12 passes through the guide member 33 is caused by bending the spring 11 downward, and after the protrusion 12 has descended to the front side, it moves upward by the action of the spring 110 until it reaches the same height as the protrusion 12 passing through the rear side. There is no risk that the vehicle will suddenly return to the rear flow line entrance again.

On the mounting surface 19 on the lower surface of the base plate 14, knitting needles 60 butts 7 selected at two positions, front and rear, are introduced into the entrances of the front and rear needle passages X and y, and the hooks of the knitting needles 6 passing through the respective needle passages On the other hand, a cam group 34 is arranged which feeds yarn from separate yarn feeders to enable two-color simultaneous knitting.

The knitting needles 6, which have been guided separately to needle threads X and Y and have undergone knitting operations, are guided laterally with the butts 7 aligned on the rear side of the lowering cam 35, and escape from the lower surface of the carriage 13.

In this configuration, the knitting needle 60 butt 7 is pushed forward by the jack 9 in front of the selection member 24 and in the selection enlargement cam 27.
In front of the selection member 24, the cam group 3 is located in front of the selection member 24.
A cutout surface 37 is formed on each outer side guide cam 36 of the lowering cam 35 in 4. The butt 7 of the knitting needle 6 pushed out by the jack 9 that collides with the cam 27 and moves forward is selected forward as the knitting needle that enters the needle passer Pass the corresponding knitting needle 6 through the rear part without moving forward, and pass the slope yl/? A knitting needle selection gum 38 that is used as a Z-entering knitting needle is provided as a part of the cam group 34.

On the upper surface of the base plate 14 is a selection member actuating device 41 that pushes the operating pin 32 of the sliding plate 29 forward against the elasticity of the spring 310 in order to make the selection member 24 protrude in front of the horizontal cam 21 at a timely manner.
will be established.

As an example of this device is shown in FIG. 7, the device includes a rack plate 42 fixed to the needle bed 1, a gear 44 rotatably supported on a shaft 43 on the base plate 14 and meshed with the rack plate 42, and A rotary pattern plate 45 is fixed to the gear 44 in a freely replaceable manner, and small protrusions 46 and large protrusions 47 in the radial direction are provided on the outer periphery of the pattern plate to match the arrangement pitch of the knitting needles 6 and jacks 9. It consists of left and right levers 48 that swing with the parts 49 in contact with each other, and a pusher plate 50 that is connected to the other end of each lever 48 and slides on the upper surface of the base plate 14. The front end of the pusher plate 50 is connected to an operating pin. It is in contact with the rear side of 32.

The small protrusion 46 of the rotating pattern plate 45 described above releases the operation pin 32 from being suppressed by the thrust plate 50 that is linked to the lever 48.
The large protrusion 47 pushes the operating pin 32 forward by the thrusting plate 50, causing the selection member 24 to protrude as shown on the left side in FIG. 2 of the front surface of the horizontal cam 21.

In the illustrated embodiment, one small projection 46 and one large projection 47 are provided alternately.

In addition to the example shown in FIG. 7, the selection member actuating device 41 may be any device that can arbitrarily control the entry and exit of the front surface -\ of the horizontal cam 21 of the selection member 24 in relation to the arrangement pitch of the bats 10.

The first embodiment described above has a sliding plate 29 provided with a selection member 24.
An embodiment in which the sensing actuating member 30 is removed constitutes an embodiment of the first invention, and an embodiment in which the sensing actuating member 30 is provided constitutes an embodiment of the second invention.

When the sensing actuating member 30 is removed from the sliding plate 29, the operating pin 32 is automatically or manually operated back and forth to project the selection member 24 to the front surface of the horizontal cam 21 or to hide it on one surface.

To explain the operation of the first embodiment, when the knitting needle 6 is pressed and moved to the rearmost position within the needle groove 2 as shown at the rightmost end in FIG. In this case, the butt 10 corresponds to the side of the first body needle passage 15 of the carriage 13, and the butt 7 corresponds to the side of the second body needle passage 18. becomes.

From that position, push jack 9 forward a little and knitting needle 6.
When you press , the butt 10 corresponds to the side of the guide passage 16,
The butt 7 corresponds to the side of the entrance of the needle passage y and becomes a specific knitting needle involved in knitting.

Therefore, when a specific plurality of jacks 9 and knitting needles 6 are pushed out to the working position and the carriage 13 is slid on the needle bed 1 in the direction of the arrow in FIG. 2, the butts 10 of the jacks 9 in the non-working position
enters the first body needle passage 15, the knitting needle 60 in the non-operating position, butt 7 enters the second body needle passage 18, and the jack 90 in the operating position.
The butt 10 enters the guide passage 16, and the butt 7 of the knitting needle 6 in the operating position enters the needle passage y.

At the same time, the gear 44 of the selection member actuating device 41 meshes with the rack 42 and rotates, and the left and right levers 48 are swung by the small projections 46 and large projections 47 of the rotary pattern plate 45.

However, the butt 7 passing through the second body needle passage 18 comes into contact with the contact surface 30a of the sensing actuating member 30 and the operating pin 32 of the sliding plate 29.
When the selection member 24 is moved forward as shown on the left side of FIG. 2, the lever 48 swings idly.

When the sensing actuating member 30 no longer comes into contact with the butt 7 of the second body needle passage 18, the selection member 24 protrudes to the front surface of the horizontal cam 21 or the lower surface of the cam 21 due to the swinging of the lever 48 and the forward and backward movement of the impingement plate 500. I hide myself.

When performing flat knitting with the knitting needles 6 in the operating position as the carriage 13 slides, the guide cam 22 is flipped up as shown by the chain line, the butts 10 are always passed through the rear guide paths a on both sides, and the knitting needle butts 7 are passed through the needle passages y. Pass.

When performing two-color simultaneous knitting, the guide cam 22 is set to the solid line position in FIG. 2, and the jack 90 butt 10, which has entered the guide passage 16 from the right side, passes through the front surface of the left side cam 21.

When the leftmost one of the group of jacks 90 in the operating position passes in front of the selection member 24 of the horizontal cam 21, the knitting needle butt 7 adjacent to the left is sensed and activated in the second body needle passage 18 as shown in the figure. Since the selection member 24 is pushed out by pushing the member 30, the jack 90 butt 10 is pushed forward and pushes the butt 7 of the front knitting needle 6 into the cutout surface 37 of the lateral guide cam 36.

In addition, the jack 9 with the butt 10 pushed out moves the protrusion 12 at the rear end to the guide member 33 along the flow line A shown by the chain line in FIG.
Move to the front side.

The movement is forced by the protruding selection member 24, but after moving forward, the elasticity of the spring 11 makes it higher than the lower edge of the guide member 33 as shown by the chain line.

Therefore, even if the butt 10 moves to the left, it will not be attracted by the permanent magnet 26, but will move forward until it hits the sorting and enlarging cam 27, and the front knitting needle 60 butt 7 will be pushed out to the front side of the knitting needle sorting cam 38. to move forward.

When the second or lower bat 10 from the right passes through the front surface of the selection member 24, the selection member 24 does not protrude to the front surface of the horizontal cam 21 or hide behind the lower surface due to the swinging of the lever 48 as described above. Therefore, the jack 9 through which the butt 10 is passed when protruded is moved by the protrusion 12 to the front side of the guide member 33 in the same way as the leftmost jack 9 described above, and the knitting needle 6 is moved to the knitting needle sorting cam by the action of the sorting enlargement cam 270. 38
When the selection member 24 is not protruding, the jack 9, which allows the bat 10 to pass through the front side, moves the protrusion 12 to the sixth position.
It moves along the rear side of the guide member 33 according to the flow line opening in the figure.

Therefore, the bat 10 is attracted by the permanent magnet 26 and moves backward along the recess 25, causing the notch 2 of the sorting and enlarging cam 2T to
Since the butt 7 does not go under the lower surface of the knitting needle 8 and push out the front knitting needle 6, the butt 7 passes behind the knitting needle selecting cam 38.

When the rightmost jack 9 in the group of jacks 9 in the operating position passes in front of the selection member 24 as shown in FIG.
Press the contact surface 30a of 0.

For this reason, the selection member 24 protrudes and pushes out the butt 10, acting in exactly the same manner as the leftmost jack 9 described above, and passes the butt 7 of the front knitting needle 6 to the front side of the needle selection and selection cam 38.

In summary, when the jack 9 enters the guide passage 16, the knitting needles 6 in the operating position are moved to the next course in accordance with the arrangement order of the small protrusions 46 and large protrusions 47 on the selection member actuating device 410 and the rotary pattern plate 45, as shown in FIG. The leftmost and rightmost butts 7 indicated by thick black lines are selected as needles that pass through the passageway The needles are always selected to pass through the needle passage X by the operation of the member 30, and this principle does not change whether the number of groups of jacks 9 entering the guide passage 16 is increased or decreased.

As shown in Fig. 8, the needles are selected so that the knitting needles 60 butt 7 at both ends of the working position are always passed through the needle thread X by hooking the knitting yarn of the instep onto the hooks of the knitting needles at both ends each time the carriage 13 is turned. The purpose of this method is to form a stitch by hooking the knitting yarn B onto the needle stems of the knitting needles at both ends of the folded end and then hooking it onto the hook of the knitting needle passing through the needle loop y. The knitted fabric structure is as illustrated in Fig. 9, and slack is generated at the folded end y' of the knitting yarn B, and when the knitting yarn with the slack y' passes along the chain line, the knitted fabric is Fig. 10 shows a second embodiment showing a modification of the first embodiment, which eliminates the drawback that the end stitches m are pulled and tightened in the direction of the arrow 1 due to the tension of the end stitches m by the knitting yarn B. The contact surface 30a of the sensing actuation member 30 provided on the sliding plate 29 of the selection member 24 is connected to the first body needle passage 1.
The structure is such that the jack 90 in the non-operating position is brought into contact with the butt 10 which protrudes from the front side into the interior of the jack 90 and which passes through the passage 15, and other parts equivalent to the first embodiment include the first embodiment, In particular, the same reference numerals as in FIG. 2 are given.

In this embodiment, the sensing actuating member 30 moves forward upon contact with the jack 90 butt 10 passing through the first body needle passage 15 and projects the selection member 24 to the front surface of the horizontal cam 21. The operation of the selection member 24 hidden on the lower surface of the horizontal cam 21 and the needle selection operation based thereon are the same as in the first embodiment.

Figures 11 to 14 show a third embodiment in which no jack is used.

Knitting needles 53V that are planted in rows with butts 54 protruding from needle grooves 52 provided in needle beds 51? - is provided with a butt and another protrusion 55 projecting upward at the rear end of the needle shaft, and its upper end is sharpened into a conical shape.

Further, the knitting needle 53 is made to be able to move up and down at the rear with the horizontal position shown in FIG.

As shown in FIG. 12, on the lower surface of the plywood 58 of the carriage 57 that is slidably mounted on the needle bed 51, there is a body passageway 59 for passing the knitting needle butt 54 in the rear body needle position, that is, the non-operating position, and a body passageway 59 in front thereof. A mounting surface 60 for a group of cams is provided on the latter mounting surface, and needle holes X, y are formed in the front and rear by a group of cams 61 according to FIG. 2 on the latter mounting surface.

The knitting needles 53 that enter separately from the right or left entrances of the needle threads A guide passage 63 is provided on each outer side of the lowering cam 62 to allow the knitting needle butt 54 to pass through the rear side of the lowering cam and move in a direction to escape from the lower surface of the carriage 57.

Its configuration is such that a rear guideway a' is provided between the rear wall 63a and the rear surface.
A horizontal cam 64 is attached to form a permanent magnet 6 on the outside.
5, a bat guiding slope 66 of the outer rear side and \ is formed on this, and a swingable guide cam 67 which is always in contact with the rear side wall 63a is provided at the inner end of the horizontal cam 64. A guide cam 68 for aligning and passing the knitting needle butt 54 is attached to the front surface of the cam, and a permanent magnet 65 is attached to the cam 68.
A needle selection protrusion 69 that bends and protrudes forward is formed on the front surface of the lateral cam 64 on the outside of the guiding inclined surface 66 of the permanent magnet 65.
A knitting needle sorter 70 is fixed to sort the knitting needle butts 54 passing in alignment between the guide cam 6B and the front surface and the rear surface.

Further, on the upper surface of the permanent magnet 65, the needle selection protrusion 69 is provided.
A triangular selection member 71 that protrudes from the front at appropriate times is provided on the rear side, and a sliding plate 72 with this member formed at the front end is attached to the base plate 58.
As shown in FIG. 11, the pin 74 is brought into contact with the lower surface of the plywood 58 as shown in FIG. Try to hide it.

A sensing actuating member 73 is provided at the rear end of the sliding plate 72 and protrudes inward from the front edge of the body measurement passage 59, and a contact surface 73a that allows the three butts 54 to contact simultaneously is provided at the rear end of the passage 59. The guide cam 76 is almost in contact with the front surface of the trapezoidal guide cam 76 protruding from the side.

Reference numeral 77 denotes a guide member that projects downwardly from the rear end edge of the plywood 58 in correspondence with the selection member 71 and its front and back, and is formed by a front and lower inclined surface, and is guided by a guide cam 67. The protrusions 55 of the knitting needles 53 are aligned and pass through the front surface of the horizontal cam 64 along the rear side of the guide member 77 to allow them to pass laterally.

In this embodiment, as in the first embodiment, when performing two-color simultaneous knitting, specific knitting needles at operating positions involved in knitting are passed through needles X and y using a known needle selection device such as a handle plate. Sort by.

(Details not shown). In the device of the embodiment, as the carriage 57 slides in the direction of the arrow in FIG. Knitting needle butt 54
When the rightmost one of the group passes through the front surface of the selection member 71, the knitting needle butt 5 in the non-operating position passes through the body passageway 59.
4 is in contact with the contact surface 73a and pushes the sensing actuating member 73 forward, so the selection member 71 also protrudes in front of the permanent magnet 65 and guides the rightmost knitting needle butt 54 (indicated by the thick black line) to the guide cam. 68 needle selection protrusion 69v? -Push it out.

Therefore, as in the case of the first embodiment, the protrusion 55 passes under the lower surface of the guide member 77 and moves to the front as shown in the flow line A.
The butt 54 moves in the horizontal direction without being attracted by the permanent magnet 65, passes in front of the knitting needle selection cam 70, and is selected as a knitting needle that will enter the needle passage X in the next course.

(Fig. 12.13) When the second and subsequent knitting needle butts 54 passing through the front surface of the horizontal cam 64 pass through the front surface of the selection member 71,
Since there are no butts in contact with the contact surfaces 73al/lc of the sensing actuating member 73 in the body measurement passage, those knitting needle butts 54 are attracted by the permanent magnet 65 and move backward along the butt guiding inclined surface 66.

Therefore, the protrusion 55 passes through the flow line opening on the rear side of the guide member 77.

The knitting needle butt 54 passes behind the knitting needle selection cam 70 and is selected as a knitting needle that will enter the needle passage y in the next course.

The leftmost one of the group of working knitting needle butts 54 is also threaded through the needle X [
They are sorted into knitting needles.

The selection of needles other than the rightmost and leftmost ends of the group of working knitting needle butts 54 is performed after the carriage 57 slides, but by moving the pin 74 back and forth in relation to the pitch of the knitting needle arrangement, it is possible to select the needles at the same time as the carriage 57 slides. It can also be done manually.

FIG. 15 shows a selection member 2 that is attached to the levers 48 on both sides shown in FIG. 7 of the first embodiment and protrudes in front of the horizontal cam 21 on the lower surface of the carriage base plate or is hidden behind the lower surface of the horizontal cam 21.
This shows a modified embodiment in which 4a is directly attached,
The same parts as in FIG. 7 are given the same reference numerals.

This example constitutes an example of the first invention of the present invention.

In the example shown in FIG. 15, the selection member 24aVC is a member corresponding to the sensing actuation member 30 of the first embodiment. The selection member 24a is operated together with the lever 48 that swings by the protrusion 46 and the large protrusion 47, and the jack 9 passes through when the selection member 24a protrudes from the horizontal cam 21.
This produces a needle selection operation in which the 0 butt 10 is pushed out and the protrusion 12 is forcibly moved to the front side of the guide member 33 according to the flow line A. By changing the arrangement of the small protrusion 46 and the large protrusion 47, it A similar needle selection operation can be performed by sliding the carriage 130 on the needle bed 1.

The present invention differs from the above-described embodiments in that the selection member 24.
24a, 71 to the jack 9 passing through the guide passage 16.63.
It is also possible to configure a needle selection device in which the protrusion 12 or 55 is forced to pass through the rear side of the guide members 33, 77 by pushing the 0 butt 10 or the knitting needle 60 butt 7 to the rear side.

The present invention has the structure and operation clarified by the above explanation, and the first invention is to align and guide the butts of knitting needles or jacks in the guiding path, and to pierce or not to pierce the butts in the front and back direction with the selection member. The system is designed to perform selection by creating a slight difference in position between whether the protrusion formed on the jack is forcibly submerged back and forth under the guide member or not. The small amount of manipulation required to go under the guide member is sufficient, and for this purpose it is sufficient to give the selection member a small amount of movement back and forth, so needle selection is possible by dividing the knitting needles or jacks into two groups: front and rear. Operation can be done quickly and accurately.

Furthermore, after the projections have been sorted into the front and back of the guide member, the projections are divided into front and rear sections by the guide member, so that the carriage can be slid without disrupting the sorting condition, and the sorting condition can be left exactly as it is. I can do it.

Further, in addition to the effects of the first invention, the second invention is configured such that the selection member is activated by a sensing actuating member that senses and activates a specific knitting needle or jack, so that it corresponds to a specific knitting needle or jack. The operating timing of a selection member that is operated is made extremely accurate, so that no deviation due to time lag occurs between the protruding action of a bat, etc., and the action of the protrusion diving back and forth behind the guide member.

Therefore, it is possible to most accurately project a predetermined bat in the front-rear direction using the selection member.
