DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circular knitting machine capable of manufacturing a pile knitted fabric excellent in design, in which a pattern is formed by a plurality of piles having different heights.

[0002]

2. Description of the Related Art Conventionally, as a circular knitting machine for producing a pile knitted fabric in which a pattern is formed by a plurality of piles having different heights from each other, that is, a multi-stage pile pattern is formed, a circular knitting machine has a depth on an outer peripheral side. There is known a configuration in which a pattern wheel (design wheel) on which a different concave pattern is formed is arranged on the rear end side of a sinker. The rear end of the sinker rotates while fitting into the concave part of the concave pattern of the pattern wheel.At this time, the advance driving amount of the sinker is regulated according to the depth of the concave part where the sinker fits, and this When the advance driving amount is large, a high pile loop is formed on the pile yarn on the sinker nose,
When the advance driving amount is small, a low pile loop is formed, and when the advance driving amount is not driven, the pile loop is not formed and is knitted together with the ground yarn to form a ground structure. A pile pattern can be obtained.

[0003]

However, the circular knitting machine using the pattern wheel has the following problems. That is, the pattern wheel has a relatively large occupied space, so that it is difficult to increase the number of mouthpieces, and therefore, the productivity cannot be improved. Further, the pattern wheel is driven by the rotation driving of the rear end of the sinker, so that the rotation speed has to be set to a low speed, and high-speed rotation cannot be performed. Further, there is a problem that setting of the pattern wheel is difficult and requires very skill. That is, for example, when changing the pattern, the pattern wheel is removed and the concave pattern on the pattern wheel is changed.
When setting the pattern wheel again after the change, if the pattern wheel is pushed too much, the needle is often not selected and the pattern is distorted, or two sinkers may enter the concave part of the concave pattern of the wheel, As described above, there has been a problem that it takes a great deal of skill to perform setting in an appropriate state.

On the other hand, as a circular knitting machine for producing a pile knitted fabric on which a pattern is formed by a single-stage pile, for example, those described in JP-B-61-53452 and JP-A-8-27649 are mentioned. Can be

[0005] That is, Japanese Patent Publication No. 61-53452 discloses that, as shown in FIG. 10, a sinker selector jack (S) is inserted into a slit (107) provided between a slit (103) for disposing a needle (102) of a cylinder (101). 1
04), the sinker selector jack (104) is selected by the actuator (105), and the sinker selector jack (104) is raised, so that the upper end of the sinker selector jack (104) and the inclined surface (106a) are moved. A circular knitting machine is described in which a sinker (106) disposed in contact with the blade is advanced to drive a pile pattern (see FIG. 9). In this circular knitting machine, a sinker selector jack (104) is provided between the needle placement slits (103) of the cylinder (101).
Is arranged, the number of needles that can be arranged is reduced to about one half compared with the conventional general cylinder,
Thus, there has been a problem that the number of stitches is greatly limited. Furthermore, sinker selector jack (104)
The slit (107) for disposing the needle (102)
It is necessary to make the depth deeper than the slit (103) for arranging the cylinder. However, such a complicated slit structure makes the manufacturing process of the cylinder complicated and difficult. Is about to be done.

Japanese Patent Application Laid-Open No. 8-27649 discloses that
A bat is provided at the rear end of the sinker, and an operating portion (finger) of an actuator is provided which abuts against the bat and directly pushes the sinker to reciprocate between a working position and a non-working position where a pile is formed. A circular knitting machine is disclosed in which a sinker is advanced by arbitrarily selecting an operation position to perform pile pattern printing. In this circular knitting machine, the butt is provided directly at the rear end of the sinker, so the mechanical strength is not sufficient.Therefore, the rotation speed of the knitting machine has to be set to a low speed, and high-speed rotation can be performed. Did not. In particular, as the gauge becomes finer, the thickness of the sinker becomes thinner, so that the bat is more likely to be damaged, and it has not been possible to cope with high-speed rotation at all.

In the circular knitting machine described in the above-mentioned JP-B-61-53452 and JP-A-8-27649,
It is impossible to manufacture a pile knitted fabric with a pattern formed by a plurality of piles having different heights from each other.However, a pattern setting mechanism in a circular knitting machine that performs pile pattern setting in one step is exemplified. This point out the problems that the pile patterning mechanism has.

SUMMARY OF THE INVENTION The present invention has been made in view of the above technical background, and is capable of setting a large number of ports, performing high-speed rotation, having a large production capacity, and a conventional general cylinder. It is an object of the present invention to provide a circular knitting machine capable of providing a multi-stage pile pattern, which can secure the same number of stitches as compared with the above, and can provide a variety of pattern changes without any restriction on the pattern change.

[0009]

An object of the present invention is to provide a knitting needle, a sinker, and at least two types of selector bats, a high-pile selector butt and a low-pile selector butt, and for driving the sinker into contact with the sinker. A swing jack having a fulcrum part serving as a swing fulcrum, and an actuator in which fingers are arranged in a manner facing the selector butt, and the at least two types of By selectively acting fingers on the selector butt, the swing jack is made to swing at different angles of rotation around its fulcrum to make the sinker advance drive amount different. This is achieved by a circular knitting machine capable of producing a multi-stage pile pattern.

By making the actuator finger act on the selector butt of the swing jack,
The swing jack is swung about its fulcrum, and the sinker is advanced by the action part to drive the pile pattern. At least two types of selector butt for high pile and low pile are used in one swing jack. It is made to have a selector bat, and by selectively operating fingers on each of these selector bats, the swing jack can be made to swing with different rotation angles, so that the sinker advance drive The amount can be varied, and as a result, a pile knitted fabric having a pattern formed by a plurality of piles having different heights can be manufactured. To explain with a specific example, for example, when a finger acts on the selector bat for high pile, the swing jack is swung by increasing its rotation angle, so that the sinker drives a large advance and patterning by high pile is performed. Done. On the other hand, when the finger acts on the selector bat for low pile, the swing jack is swung by reducing its rotation angle, so that the sinker is driven forward a little and patterning by low pile is performed. When the finger does not act on any of the selector bats, the pile yarn is knitted together with the ground yarn to form a ground knitting structure.

In the circular knitting machine having this configuration, the thickness of the swing jack can be set to be larger than the thickness of the sinker as shown in FIG. 6 (for example, the thickness is set to twice or more the thickness of the sinker). Therefore, sufficient mechanical strength can be ensured, and there is no risk of causing damage to the selector butt, so that high-speed rotation can be performed. That is, as shown in FIG. 6, the thickness of the sinker cannot necessarily be set large in relation to the arrangement of the knitting needles between the sinkers, and the thickness of the sinker is directly set on the rear end of the sinker. Although the mechanical strength cannot be sufficiently secured in the configuration in which the bat is provided, the present invention is not a sinker, but a configuration in which the selector butt is provided in a swing jack capable of securing a sufficient thickness in strength, This makes it possible to perform high-speed rotation.

Further, the circular knitting machine of this configuration is provided with a swing jack and an actuator as means for forming a multi-stage pile pattern, and occupies less space than a conventional pattern wheel. Can be more. Further, since the swing jack is not disposed in the slit of the cylinder, there is an advantage that the same number of needles can be secured as compared with a conventional general cylinder.

In the above circular knitting machine, the fulcrum is provided at one end in the length direction of the swing jack, the action portion is provided at the other end, and the selector butt is provided at an intermediate portion in the length direction of the swing jack. Preferably.
Since the fulcrum and the action part are provided at both ends separated from each other, and the selector butt is provided in the middle part, even if the action amount is small with respect to the selector butt, the action part is with respect to the sinker. Advancing drive can be performed with a sufficient amount, and thus higher-speed rotation can be performed.

The at least two types of selector bats are formed so that the butt protrusion lengths thereof are different from each other, so that the rotation angle of swing of the swing jack can be made different by the difference in the protrusion lengths. Preferably, it has been done. Just by forming the butt protrusion lengths to be different from each other, that is, it is possible to make the rotation angle of swing of the swing jack different with a simple structure,
Cost reduction can be achieved.

The finger acting on the selector butt for high pile and the finger acting on the selector butt for low pile are arranged so as to be shifted to the front and rear positions in the rotation direction of the cylinder (that is, shifted to the left and right directions). The side surface of the guide groove of the sinker cam where the butt abuts is formed in a stepped shape corresponding to the arrangement position of each finger, and the degree of advance of the sinker is individually regulated by each stepped portion. Is preferred. The position where the finger acts on the high pile selector butt to drive the sinker and the position where the finger acts on the low pile selector butt to drive the sinker are shifted to the front and rear positions in the cylinder rotation direction. Therefore, the inertia of the sinker when the sinker is pushed by the swing jack is stopped by each step of the butt contact side surface in the guide groove, and the degree of advance of the sinker is individually regulated. Therefore, even when a finger acts on any of the selector bats, the sinker can be advanced and driven by a desired advanced drive amount with high accuracy, so that a high-quality pile knitted fabric having no pattern deviation or the like can be manufactured.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a circular knitting machine capable of forming a multi-stage pile pattern according to the present invention will be described with reference to the drawings. In the circular knitting machine (1) shown in FIG. 1, (2) is a cylinder, (3) is a sinker cam, (4) is a sinker, (5) is a needle cam, and (6) is a knitting needle.

The cylinder (2) is a circular ring, and is configured to be rotatable in a horizontal plane around the center of the circle. A circular sinker ring (25) is also formed on the outermost peripheral side of the uppermost portion of the cylinder (2).
The sinker ring (25) is also configured to be able to rotate in the same direction in the horizontal plane in conjunction with the rotational drive of the cylinder (2). A plurality of grooves are provided on the upper surface of the sinker ring (25), and the sinkers (4) are arranged so as to fit into the respective grooves, and the sinkers (4) are arranged in the axial direction (that is, the center of the cylinder). It is allowed to move forward and backward in the radial direction connecting the position and the sinker). In addition, sinker ring (25)
A sinker cam (3) is disposed above the sinker cam (3), and a guide groove (20) of a predetermined shape is provided on the bottom surface of the sinker cam (3) and continuously extends over the entire circumference. A convex bat (21) is provided at the center, and the bat (21) is arranged so as to fit into the guide groove (20). Therefore, when the sinker ring (25) is driven to rotate in conjunction with the rotation of the cylinder (2), the sinker (4) also rotates in the same rotational direction, but at this time, it corresponds to the groove shape of the guide groove (20) of the sinker cam. Then, the bat (21) also moves forward and backward in the axial direction of the sinker (4), and accordingly, the sinker (4) is driven to move forward and backward in the axial direction while rotating around the cylinder (2). .

A plurality of grooves are provided on the outer peripheral surface of the cylinder (2), and knitting needles (6) are arranged so as to fit into these grooves. (Up and down direction). Further, on the outer peripheral side of the cylinder (2), a needle cam (5) also having a circular ring shape is arranged. The inner peripheral surface of the needle cam (5) is provided with a guide groove (23) of a predetermined shape which continuously extends over the entire circumference, while a protruding bat (24) is provided below the knitting needle (6). The butt (24) is provided with the guide groove (2).
It is arranged so as to fit into 3). Accordingly, when the cylinder (2) is rotationally driven, the knitting needle (6) also rotates in the same rotation direction. At this time, the butt (24) also moves in the axial direction of the knitting needle (6) in accordance with the groove shape of the guide groove (23). The knitting needle (6) is driven to move up and down, so that the knitting needle (6) is driven to move up and down in the axial direction, that is, in the vertical direction, while rotating around the outer circumference together with the cylinder (2).

The continuous groove shape over the entire circumference of the guide groove (20) in the sinker cam (3) and the continuous groove shape over the entire circumference of the guide groove (23) in the needle cam (5) are formed by the sinker ( The forward / backward drive of 4) and the raising / lowering drive of the knitting needle (6) are linked to each other, that is, the sinker (4) and the knitting needle (6) cooperate to knit a pile knitted fabric, so that the pile knitted fabric is knitted. It is formed in.

The above configuration is a configuration known as a circular knitting machine. However, in the above configuration in which the sinker (4) is driven forward and backward by the guide groove (20) of the sinker cam (3), the pile stitch is fine. It is difficult to change,
Although it was not possible to perform pile patterning arbitrarily, the present invention is further provided with the following configuration, whereby patterning is performed by a plurality of piles having different heights. This makes it possible to manufacture piled knitted fabric.

That is, at the rear end side of each sinker (4),
The swing jacks (40) are arranged in such a manner that the length direction thereof extends along the vertical direction. These swing jacks (40) are provided on the outer peripheral surface of the sinker ring (25) in correspondence with the plurality of grooves (grooves on which the sinker is provided) provided on the upper surface of the sinker ring (25). Are arranged so as to be fitted into the groove of the groove, and can freely swing in the groove.

The upper end of the swing jack (40) is substantially L
It is bent and extended in the shape of a letter, and the action part (41)
Is formed, and a bat (4
5) is formed projecting upward. The working part (41)
Are arranged so as to face the rear end of the sinker (4),
When the swing jack (40) swings, the action section (41) contacts the rear end of the sinker (4) to drive the sinker (4) to advance. On the other hand, a fulcrum (42) is formed at the lower end of the swing jack (40). That is, a notch recess (42a) is provided at the lower end of the swing jack (40), and the notch recess (42a) is provided.
A fixed swing shaft (47) is arranged in a) so that the entire swing jack (40) can swing around the swing shaft (47). The swing shaft (47) includes a sinker ring (2).
A ring-shaped spring band inserted and arranged in the notch recess (42a) from the outer peripheral side of 5) is used.

In the middle part of the swing jack (40) in the longitudinal direction, a selector butt (43) for high pile is formed so as to protrude toward the outer peripheral side (opposite to the action part) at the upper end side. On the other hand, at a position on the lower end side, a selector butt (44) for low pile is formed so as to protrude toward the outer peripheral side. The projecting length of the selector butt (43) for high pile is longer than the projecting length of the selector butt (44) for low pile. Therefore, the rotation angle at which the swing jack (40) swings by the action of the finger (51) described later on the high pile selector butt (43) depends on the action of the finger (52) described later on the low pile selector butt (44). By doing so, the rotation angle at which the swing jack (40) swings becomes larger, so that the sinker (4) can be driven forward by a corresponding amount.

In the circular knitting machine of the present embodiment, four types of swing jacks (40) are used. As shown in FIG. (43) and a low-pile selector butt (44), which are arranged so that their positions are different from each other. That is, there are four locations where the high pile selector butt (43) is shifted vertically, and four locations where the low pile selector butt (44) is vertically shifted.

Eight fingers are arranged corresponding to the positions of these selector bats so as to face them. That is, the selector butt for high pile (4
High pile fingers (51), (51), (51) and (51) are provided corresponding to the four positions of (3), whereas low pile fingers are provided corresponding to the four positions of the low pile selector butt (44). Finger (52) (5
2) (52) and (52) are provided. The operation of each of these fingers is controlled by an actuator (50).
3) When acting on (44), the finger is caused to act slightly diagonally downward, while when not acting on any of the selector butts (43) and (44), all fingers are actuated. The finger is controlled so as to be slightly inclined obliquely upward and in the inoperative position.

The tips of the fingers (51) and (52) are formed on inclined surfaces, and the selector butts (43) and (44) are guided on the inclined surfaces to guide the selector butt (4).
3) Since it acts on (44) and swings it, the selector butt (43) (44) slides very smoothly, which has the advantage of being able to operate at higher speeds. .

As shown in FIG. 5, a swing jack (40) is formed on the bottom surface of the sinker cam (3) along with the guide groove (20) for guiding the bat (21) of the sinker (4). A guide groove (48) for guiding the bat (45) is provided.
The continuous groove shape over the entire circumference of 8) is the sinker (4)
Is formed in a shape corresponding to the groove shape of the guide groove (20) for guiding the groove.

The actuator (50) is arranged on the outer peripheral side of the sinker cam (3) as shown in FIG.
The four low pile fingers (52), (52), (52), and (52) are arranged in a line in the vertical direction by the actuator (50) so as to protrude toward the inner circumferential direction of the sinker cam (3). The four high-pile fingers (51), (51), (51), (51) are shifted (to the right in the drawing) from the position of the low-pile fingers (52) in the rotational direction of the cylinder (2). Similarly, they are arranged in a line in the vertical direction so as to protrude toward the inner peripheral direction of the sinker cam (3).

On the other hand, the guide groove (2) of the sinker cam (3)
The groove shape of 0) has the following characteristic shape corresponding to the configuration in which the low pile fingers (52) and the high pile fingers (51) are displaced as described above. . That is, of the side surfaces of the guide groove (20) where the bat (21) abuts, portions corresponding to the forward positions of the low pile fingers (52) and the high pile fingers (51) in the protruding direction are formed in a stepped shape. I have. That is, as shown in FIG.
A first step (61) is formed such that the side surface of (0) is lowered inward from the base portion (60) at a position forward of the low-pile finger (52) in the protruding direction, and a high-pile finger (51) is formed. At the front position in the protruding direction, the second step (62) is further lowered to the inner peripheral side from the first step (61).
Are formed.

The swing jack (40) described above
Similarly, the guide groove (48) for guiding the bat (45) has a step-like portion corresponding to the front position in the protruding direction of the low-pile finger (52) and the high-pile finger (51). That is, as shown in FIG. 5, the side surface of the guide groove (48) is located at a position forward of the low pile finger (52) in the protruding direction, and
3) A first step portion (64) is formed further inward from the first step portion (64) at a position forward of the high pile finger (51) in the protruding direction. A two-step portion (65) is formed.

The selector butt for high pile (43) and the selector butt for low pile (44)
When the fingers (51) and (52) do not act on any of the above, the swing jack (40) does not swing as shown in FIG. ), And the bat (21) of the sinker (4) moves along the line of the base (60) of the sinker cam (3), so that the sinker (4) is not driven to advance. Therefore, the pile yarn (70)
Is the sinker base stage (32) together with the ground thread (71)
On top, the pile yarn (70) is knitted with the ground yarn (71) to form a zero pile (70a) without height.

On the other hand, the low pile fingers (5
When 2) acts on the low pile selector butt (44), as shown in FIG. 3, the swing jack (40) swings at a small rotation angle about its fulcrum (42), Since the action portion (41) comes into contact with the sinker (4), the butt (2) of the sinker (4)
1) advances until it comes into contact with the first step portion (61) of the sinker cam (3) (see FIG. 5), whereby the sinker (4)
Is driven to the position where the first shelf (30) overlaps the knitting needle (6). Accordingly, the pile yarn (70) is placed on the first shelf (30) by the lowering of the knitting needle (6), and a lower loop is formed by the further lowering of the knitting needle (6), and further, the inside of the already formed stitch is formed. A low pile loop (low pile loop) (70b) is formed on the ground knitted structure by being inserted.

On the other hand, when the high pile finger (51) acts on the high pile selector butt (43), as shown in FIG.
0) swings around the fulcrum (42) at a large rotation angle, and its action part (41) comes into contact with the sinker (4), so that the bat (21) of the sinker (4) is 3) (see FIG. 5) until the second shelf (62) comes into contact with the second step (62), whereby the second shelf (31) of the sinker (4) is driven to advance to a position where it overlaps the knitting needle (6).
Accordingly, the pile yarn (70) is put on the second shelf (31) by the lowering of the knitting needle (6), and a higher loop is formed by the further lowering of the knitting needle (6), and further the inside of the already formed stitch is formed. A high pile loop (high pile loop) (70c) is formed on the ground knitting structure by being inserted.

By appropriately selecting and performing the above three types of knitting operations, as shown in FIG. 8, two-stage piles having mutually different heights (when a zero pile is inserted, three piles are formed).
The pattern was formed by the step, that is, the ground thread (7
With respect to the ground knitting structure in which the zero pile (70a) is knitted with respect to 1), a pattern by the low pile loop (70b) appears, and the high pile loop (H) is higher than the low pile loop (70b). It is possible to manufacture a pile knitted fabric having an excellent design, in which the pattern according to 70c) is further revealed.

The circular knitting machine (1) having the above-mentioned configuration is provided with a swing jack (40) and an actuator (50) as means for forming a multi-stage pile pattern, and occupies a smaller space than a conventional pattern wheel. Is small and the number of mouths can be increased, so that the production amount can be increased. Further, since the swing jack (40) is not disposed in the slit of the cylinder, the same number of needles can be secured as compared with a conventional general cylinder.

In this embodiment, the finger (51) acts on the high pile selector butt (43) to move the sinker (4) forward and the finger (52) acts on the low pile selector butt (44). As a result, the position at which the sinker (4) is driven to advance is shifted to the front / rear position, so that each step (61) (62) of the side face of the guide groove (20) contacting the bat (21).
Thus, the degree of advance of the sinker (4) can be individually regulated, so that the sinker (4) can be advanced and driven by a desired advance drive amount with high accuracy.

In this embodiment, four types of swing jacks (40) in which the positions of the high-pile selector butt (43) and the low-pile selector butt (44) as shown in FIG. , The degree of advance of the sinker (4) can be freely changed between the sinkers (4) and (4) adjacent to each other, and therefore, the degree of freedom in pattern design And there is an advantage that very precise patterning can be performed.

The type of the swing jack (40) is not limited to four types, but may be other plural types or one type.

In this embodiment, the swing jack (40) has two types of selector bats, a high pile selector butt (43) and a low pile selector butt (44). May be adopted. For example, in addition to the low-pile selector butt and the high-pile selector butt, a configuration having a selector butt with a longer butt protruding length than these may be used. In such a case, three stages having different heights from each other may be used. It is possible to manufacture a pile knitted fabric on which a pattern is formed by a pile (four steps when a zero pile is inserted).

Further, in this embodiment, the butt projection length of the high pile selector butt (43) is set to be longer than the butt projection length of the low pile selector butt (44). The rotation angle of the swing of the swing jack (40) is larger when the finger (51) acts on the 43) than when the finger (52) acts on the selector butt (44) for low pile. However, the means for varying the rotation angle of the swing of the swing jack (40) is not particularly limited to such a configuration, and may be, for example, the fingers (51) (5).
By configuring the projection lengths of 2) to be different from each other, the rotation angle of the swing of the swing jack (40) may be different. However, it is preferable to adopt the configuration as in the present embodiment in that the structure is simple and the cost is further reduced.

The circular knitting machine according to the present invention is not particularly limited to the above embodiment, and various design changes can be made as appropriate without departing from the technical idea of the present invention.

[0042]

According to the circular knitting machine according to the first aspect of the present invention, the swing jack swings around its fulcrum by operating the finger of the actuator on the selector butt of the swing jack. It is to perform the pile pattern by driving the sinker to advance in the part, but in one swing jack is to have at least two types of selector butt of a high pile selector bat and a low pile selector bat,
By selectively acting fingers on each of these selector bats, the swing jack can be made to swing by changing its rotation angle, so that the advance driving amount of the sinker can be made different,
Therefore, it is possible to manufacture a pile knitted fabric having a pattern formed by a plurality of piles having different heights.

Further, since the thickness of the swing jack can be set to be larger than the thickness of the sinker, sufficient mechanical strength can be secured in the selector butt, and there is no possibility that the selector butt will be damaged. Therefore, there is an advantage that high-speed rotation can be performed.

Further, the swing jack and the actuator, which are pile design means, occupy a small space, so that the number of mouths can be increased. Further, since the swing jack is not arranged in the slit of the cylinder, the same number of needles can be secured as compared with a conventional general cylinder.

According to the second aspect of the present invention, the above effects can be surely received.

According to the third aspect of the present invention, since the rotation angle of the swing of the swing jack can be made different with a simpler structure, the cost can be reduced.

According to the fourth aspect of the present invention, the sinker can be advanced and driven by a desired advance drive amount with high accuracy even when a finger acts on any of the selector bats. A pile knitted fabric can be manufactured.
