Abstract

Provided are a sinker that is unlikely to cause the positions of a plating yarn and a ground yarn to be reversed unintentionally, and a knitting mechanism using the sinker. In a knitting mechanism with which plating knitting can be performed on a circular knitting machine, a sinker has a first transition surface and a second transition surface on a sinker top thereof. Either a first route or a second route is selected as a movement route for the sinker. The first route brings the first transition surface into the closest proximity to a knitting needle when the knitting needle is being lowered, and allows the knitting needle to be lowered in this state to the lowest point of a movement route of the knitting needle. The second route brings the second transition surface into the closest proximity to the knitting needle when the knitting needle is being lowered, and allows the knitting needle to be lowered in this state to the lowest point of the movement route of the knitting needle. Thus, during plating knitting on the circular knitting machine, knitting can be performed by interchanging positions of a first yarn and a second yarn.

Description

Jacquard knitted fabric knitting mechanism in circular knitting machine, knitting method using the knitting mechanism, and sinker used in the knitting mechanism

The present invention relates to a knitting mechanism for knitting a jacquard knitted fabric by plating knitting in a circular knitting machine, a knitting method using the knitting mechanism, and a sinker used in the knitting mechanism.

Conventionally, for example, a plating knitting in which two ground threads and a plating thread are supplied to a knitting needle, and the parallel threads are aligned and knitted to form one stitch is known. Therefore, the stitches of the thread on the front side appear on the surface, and the stitches of the thread on the back side appear on the back side, so that it is possible to weave a fabric in which stitches formed by the threads on the back side and the front side are different.

On the other hand, a method of knitting a jacquard knitted fabric by a needle selection device is generally known. This is by using the needle selection device of the knitting needle to select the track of each knitting needle from the stitching, tucking, and floating thread, so as to present a free pattern on the surface of the fabric.

Moreover, in recent years, there has been an increased demand for lighter and smoother fabrics with a freer pattern in accordance with the demand for higher quality fabrics. As one of the methods of knitting such a woven fabric, a plated jacquard knitting in which a free pattern is exhibited on the woven fabric surface by exchanging the positions of the two threads in this knitting has been performed conventionally.

For example, US Pat. No. 1,977,590 discloses a knitting mechanism that uses various sinkers to change the position of the thread. This is a mechanism for changing the position of the wire by using a variety of sinkers.

Here, the sinker jaw refers to the upward direction on the sinker for the thread to come into contact with when the knitting needle catches the thread on the hook and descends to the lowest point of the movement track of the knitting needle in ordinary single-jersey knitting. On the horizontal plane, the size of the loop is determined by the distance between the knitting needle and the sinker jaw. The sinker nose is spaced apart from the sinker jaw above the sinker jaw, and is integrally formed with the sinker jaw. The sinker nose is a portion that protrudes forward in the direction that is the center of the barrel. The needle cylinder refers to a circular member that accommodates the knitting needles of the circular knitting machine. The sinker nose forms a groove (sinker throat) with the sinker jaw. The sinker throat acts to press the old coil when the needle is moved up and down. The sinker butt formed at the rear of the sinker is engaged with the groove of the sinker cam, and the sinker dial that accommodates the sinker rotates, so that the sinker butt is guided by the fixed sinker cam to move the sinker back and forth. . Let the direction in which the sinker butt protrudes be upward, and let the opposite direction be downward. The direction in which the sinker butt is formed when viewed from the entire sinker is the rear, and the opposite direction is the front.

In addition, for example, Japanese Patent No. 6696035 discloses a knitting mechanism of a needle selection device using special sinkers and knitting needles. This is to change the position of the two threads by changing the time point at which the knitting needle descends relative to the time point at which the sinker is advanced once, so as to select whether to advance the position of the ground wire. Choose whether to put the ground wire in the sinker throat or push the ground wire with the sinker nose to change the position of the wire. [Prior Art Literature] [Patent Literature]

[The problem to be solved by the invention]

In the knitting mechanism described in Patent Document 1, many types of sinkers are required for one circular knitting machine, and the number of parts increases and the cost also increases. In addition, securing a space for placing various types of sinkers requires a correspondingly large space for knitting needles, reducing the number of needles, and there is a problem in that the demand for fine-density fabrics with a finer gauge cannot be met.

In addition, in the knitting mechanism described in Patent Document 2, since the position of the thread in the hook is operated at a height above the sinker nose, the distance from the sinker jaw on which the stitches are formed is long, and the two threads are separated from each other. Since the position of the wire before descending to the sinker jaw is unstable, the positions of the two wires are exchanged and so-called inversion is likely to occur. In addition, since the action of pushing the wire such as the ground wire with the sinker nose is large, a load is applied to the wire, so that backlash occurs, which also causes the reverse rotation.

An object of the present invention is to provide a plated jacquard knitting in which the positions of the ground thread and the plated thread are exchanged in the plating knitting in view of the above-mentioned problems, without increasing the types of sinkers, and can meet the requirements of knitting a fabric with a finer gauge. , a knitting mechanism that is difficult to reverse with yarn and ground wire, and a sinker using this knitting mechanism. [means to solve the problem]

The knitting mechanism of the present invention can perform knitting by exchanging the positions of the first thread and the second thread during the operation of the circular knitting machine in the plating knitting of the circular knitting machine, and is characterized in that: The knitting mechanism has: a knitting needle that moves up and down; and a sinker that moves horizontally back and forth in a manner orthogonal to the knitting needle, The sinker has a first transition surface and a second transition surface on the sinker jaw, and the first transition surface is directed forward from a first height, which is the height of the sinker jaw, to a second height different from the first height. The transition surface, the second transition surface is a surface transitioning forward from the second height to the first height, For each of the aforementioned sinkers, the action track of the aforementioned sinker is selected as any one of the first track and the second track, In the first track, during the descending process of the knitting needle, the first transition surface is made closest to the knitting needle, and in this state, the knitting needle is lowered to the lowest point of the movement track of the knitting needle, In the second track, during the descending process of the knitting needle, the second transition surface is brought closest to the knitting needle, and the knitting needle is lowered to the lowest point of the movement track of the knitting needle in the state of the approaching position, Thereby, in the plating knitting of the circular knitting machine, the positions of the first thread and the second thread can be exchanged and knitting can be performed.

In the present invention, the vertical direction is expressed as high up and low down. The sinker jaw is basically an upward horizontal plane with a fixed height. Take this height as the first height. The present invention has a first transition surface and a second transition surface on the sinker jaw. Also, in the same manner as the sinker for a general single jersey circular knitting machine, the sinker jaws face parallel to the lower surface of the sinker nose. The first transition surface faces forward and transitions from a first height to a second height different from the first height. Therefore, the first transition surface can be said to be an inclined surface or curved surface that transitions from the sinker jaw to the second height. The second transition surface can be said to be an inclined surface or a curved surface that faces forward and transitions from the second height to the first height. Thereby, in the front-rear direction, the first transition surface and the second transition surface are opposite to each other in the direction of height. In addition, the second height is lower than the height of the lower surface of the nose of the sinker. Thereby, the first transition surface and the second transition surface are prevented or reduced from contacting with the coil and hindering the movement of the coil.

In the present invention, any one of the first rail and the second rail is selected for each sinker. Some sinkers select the first track, and other sinkers select the second track. On the first track, the sinker moves in such a way that the first transition surface is closest to the needle. The sinker then maintains its position until the needle is lowered to the lowest point of the motion track. On the second track, the sinkers move in such a way that the second transition surface is closest to the needles. The sinker then maintains its position until the needle is lowered to its lowest point. When the first or second transition surface is closest to the knitting needle, a part or all of the first or second transition surface is located in the area between adjacent knitting needles. When the knitting needle catches the thread and reaches the lowest point of the motion track, a loop is formed by the hook of the knitting needle and the sinker jaws adjacent to the knitting needle. On the first track, the second thread moves in a direction lower than the first transition surface in the front-rear direction, and then the knitting needle is lowered, and the first thread is formed in a state opposite to the direction in which the second thread moves. coil. In addition, on the second track, the second thread moves in a direction lower than the second transition surface in the front-rear direction, and then the knitting needle is lowered, and the first thread moves in a direction opposite to the direction in which the second thread moves. The state forms a coil. Since the lower positions of the first transition surface and the second transition surface are in opposite directions, in the hook of the knitting needle, the position of the thread is opposite to the first track. Thereby, the positions of the first wire and the second wire are reversed to form the coil for the coil formed on the first track and the coil formed on the second track.

Thereby, the positions of the first thread and the second thread can be exchanged during plating knitting, and the first thread and the second thread are guided back and forth at positions relatively close to the sinker jaws, thereby further preventing the possibility of inversion. In addition, the load on the wire such as the sinker pressing the wire can be reduced, the amount of movement of the wire can be reduced, and the possibility of inversion can be further suppressed.

The aforementioned knitting mechanism includes: a sinker cam which can guide each sinker to the first rail or the second rail; and a needle cam which guides each knitting needle.

Thereby, the sinker is guided to any one of the first rail or the second rail through the sinker cam, and the knitting needle is guided to the operation rail through the needle cam. The knitting needle moves up and down through the movement track of the knitting needle. The knitting needle descends in a state where the first transition surface or the second transition surface is close to the movement of the sinker, and after descending to the lowest point of the movement track of the knitting needle, it performs a vertical movement of rising again. The sinker cam may not guide all of the motion orbits of the sinkers. For example, a structure in which both the first rail and the second rail can be selected may be selected, and the sinker selection device may guide them to either side.

Moreover, it is preferable that the said knitting mechanism has a sinker selection device which selects any one of a 1st rail and a 2nd rail with respect to the operation rail of each sinker.

The present invention does not originally limit the selection method of the action orbit of the sinker. However, it is preferable to have a sinker selection device which has no limitation on the size and the like of the pattern. However, for example, by increasing the types of sinkers having cams and corresponding sinker butts, it is possible to select the first rail and the second rail even without a selection device, and to exchange the first thread and the second rail during plating knitting. The position of the second thread, the weave pattern.

In addition, the movement track of the knitting needle of the knitting mechanism is fixed.

In the knitting mechanism of the present invention, the needle selector of the knitting needle selects three routes of the operation trajectory of the portion where the knitting needles, such as stitching, tucking, and floating, which are conventionally present, rise and then descend in order to receive the thread. Different weaving structures such as mesh weave can be added. In this case, all the knitting needles have the same trajectories except for the parts where the motion trajectories are different among stitching, tucking, and floating. In the case of not knitting a pattern formed by such a needle selection device for knitting needles, the movement orbits of the knitting needles may all be the same orbit, and by selecting the movement orbits of the sinkers, the first thread and the second thread can be exchanged. position for plated jacquard weave.

For example, the first transition surface may be an inclined surface that is high in the front and low in the rear, and the second transition surface is an inclined surface that is low in the front and high in the back, so that when the sinker is on the first rail, the first line is formed in the front. While the second wire is at the back of the coil, when the sinker is on the second track, the first wire is at the back and the second wire is at the front.

Accordingly, a protrusion is formed on the sinker blade jaw, and the first transition surface and the second transition surface are formed on the protrusion. And, the 1st transition surface is formed in the back of this protrusion part, and the 2nd transition surface is formed in the front. When the sinker is on the first rail, it is guided forward and controlled so that the first transition surface approaches the knitting needle. On the other hand, when on the second rail, the sinker is guided to the rear of the first rail, and the second transition surface is controlled so that the second transition surface approaches the knitting needle. Thereby, the position of the thread in the hook can be changed, and the position of the thread of the knitted plating stitch can be reversed in the front and rear.

In the knitting mechanism of the present invention, above the first transition surface, the nose of the sinker protrudes from the rear toward the front, and the tip of the nose of the sinker is formed to be located rearward of the tip of the first transition surface.

Thereby, the front end of the sinker nose is positioned upward in the vertical direction of a part of the rear of the first transition surface. When viewed from the tangential direction of the circumference of the cylinder of the circular knitting machine, in the knitting process, when the hook of the knitting needle is lowered to the vicinity of the sinker nose, the area inside the hook of the knitting needle is in the sinker. There is space in front of the nose. In the present invention, before the hook of the knitting needle passes the height of the upper surface of the nose of the sinker, the sinker selects the position where the first transition surface or the second transition surface reaches the front side of the knitting needle. The front side refers to the area between adjacent knitting needles. Viewed from the tangential direction of the circumference of the needle cylinder of the circular knitting machine, it is the position where the knitting needle overlaps the first transition surface or the second transition surface. The sinker then remains in this position until the needle reaches the lowest point of the motion track. Therefore, when the knitting needle catches the thread and descends, the thread passes through the space, and the thread is naturally guided forward. Thereby, the distance from the wire guided backward becomes large, and the possibility of inversion is reduced.

In another structure, the first transition surface may be a sloped surface that is high in the rear and low in the front, and the second transition surface may be a sloped surface that is low in the rear and high in the front, whereby when the sinker is on the first rail, the first transition surface is formed. When the first line is located in the back and the second line is located in the front, the sinker is on the second track, forming a coil with the first line in the front and the second line in the back.

Accordingly, a recessed portion is formed in the sinker jaw, and the first transition surface and the second transition surface are formed on the recessed portion. Furthermore, a first transition surface is formed at the rear of the recessed portion, and a second transition surface is formed at the front. The sinker is guided forward on the first rail, and is controlled so that the first transition surface approaches the knitting needle. On the other hand, when on the second rail, the sinker is guided to the rear of the first rail, and the second transition surface is controlled so that the second transition surface approaches the knitting needle. Thereby, the position of the thread in the hook can be changed on the first orbit and the second orbit of the operation orbit of the sinker, and the position of the thread of the plating stitch to be knitted can be reversed in the front and rear.

Preferably, the inclination angle of the first transition surface with respect to the horizontal is the same as the inclination angle of the second transition surface with respect to the horizontal.

In the present invention, for example, when the second height is higher than the first height, the protrusion of the first transition surface toward the forward ascending slope is present on the sinker jaw, and the protrusion of the second transition surface facing the forward descending slope is present on the sinker on the jaw. At this time, the second wire is guided to the rear end of the first transition surface through the first transition surface, and the second wire is guided to the front end of the second transition surface through the second transition surface. These positions are the same first height as the sinker jaws. On the other hand, when the hook of the knitting needle passes through the vicinity of the height of the sinker jaw, the first thread is guided in the direction of the second thread through the first transition surface or the second transition surface. The second wire has been located at the rear end of the first transition surface as the first height or the front end of the second transition surface, and the first wire is guided to a position adjacent to the second wire on each transition surface side. If the inclination angle of the first transition surface relative to the sinker jaw is the same as the inclination angle of the second transition surface relative to the second sinker jaw, the height of the first thread is approximately the same no matter on which track, and the The length of the stitch of the first thread formed by bending the yarn toward the lowest point of the motion track is also the same. Since the first wire is adjacent to the second wire, the position of the first wire is opposite to the front and rear of the second wire on the first track and the second track, but no matter which track the sinker is on, the coil of the first wire are approximately the same length.

Preferably, the knitting mechanism of the present invention includes a yarn guide for supplying the first thread and the second thread to the knitting needles, the second thread is supplied so as to be located below the first thread, and the second thread is supplied at a position lower than the first thread. A line earlier in time is directed to the first transition surface or to the second transition surface.

Accordingly, the knitting mechanism of the present invention includes the yarn guide, and the second thread is fed so that it is positioned below the first thread. Thereby, the second wire reaches the first transition surface or the second transition surface earlier than the first wire, and is guided and moved in a direction lower than the front and rear of the first transition surface or the second transition surface. The second wire is guided by the first transition surface or the second transition surface formed on the sinker jaw, so that the second wire is guided on the sinker jaw. Then, as the needle descends, the first thread is also guided to the first or second transition surface. The first line is guided by the first transition surface or the second transition surface in a lower front-to-rear direction at a later point in time than the second line, and is located adjacent to the already guided second line. Therefore, the position of the thread is guided on the sinker jaw, and the hook of the knitting needle descends downward compared to the sinker jaw, and the thread position is determined, and then reversed in the state that each thread does not move directly and greatly. There is less room for reversal.

Preferably, in the plating knitting of two feeder repeats, the second thread is supplied into the hook of the knitting needle in the first supply path, and the first thread is supplied in the next supply path. into the hook of the knitting needle.

In order to prevent reverse rotation, the knitting needle is raised in the first supply path, the second thread is supplied into the hook of the knitting needle, and the hook of the knitting needle is temporarily lowered to the vicinity of the sinker jaws. In the next supply path, the knitting needle is raised again. At this time, even if the knitting needle is raised, the second thread is pressed by the lower surface of the sinker nose, and the position near the sinker jaw becomes the second thread hooked on the needle opened by the knitting needle. The state of the tongue is guided toward the lower side of the first transition surface. On the other hand, the first thread is fed into the hook from above, the positions of the first thread and the second thread can be separated, and the reverse rotation can be further suppressed. Since the two supply paths are repeated plating knitting, the knitting needles do not descend to the lowest point of the rail in the first supply path. Thereby, the old loops are not detached from the knitting needles (the loops will not come off). After the second supply path, the knitting needle descends to the lowest point of the track, and the old stitch is unhooked.

In another configuration, in the plating knitting in which one supply path is repeated, in all supply paths, the first thread is supplied into the hook of the knitting needle from a position higher than the second thread, and the second thread is supplied from a position higher than the second thread into the hook of the knitting needle. The low position of the first thread is fed into the hook of the knitting needle.

According to this configuration, since the first line and the second line are inserted into one supply channel, the two lines are close to each other, and the possibility of inversion is increased. However, since the number of supply channels is increased, the yield can be improved. It is effective if the knitting conditions such as the type of thread and the tightness of the stitch are difficult to reverse.

The knitting method of the present invention is a plated jacquard knitting method using the above-mentioned knitting mechanism.

Therefore, in the above-mentioned knitting method, in the plating knitting of the circular knitting machine, the knitting needles that move up and down and the sinkers that move horizontally back and forth so as to be orthogonal to the knitting needles are exchanged during the operation of the circular knitting machine. The method of knitting according to the position of the first thread and the second thread, The sinker has a first transition surface and a second transition surface on the sinker jaw, and the first transition surface is from a first height, which is the height of the sinker jaw, to a second height different from the first height. The front transition surface, the second transition surface is a surface transitioning forward from the second height to the first height, Select any one of the first track and the second track for the action track of the sinker, The first track makes the first transition surface closest to the knitting needle during the descending process of the knitting needle, and in this state, the knitting needle is lowered to the lowest point of the movement track of the knitting needle, In the second track, during the descending process of the knitting needle, the second transition surface is the closest to the knitting needle, and in this state, the knitting needle is lowered to the lowest point of the movement track of the knitting needle, Thereby, knitting can be performed by a knitting method in which the positions of the first thread and the second thread can be exchanged in the plating knitting of the circular knitting machine. In addition, knitting can be performed by a knitting method using the aforementioned knitting mechanism.

The sinker of the present invention is a sinker for plated jacquard knitting having a sinker nose and a sinker jaw, characterized in that the lower surface of the sinker nose of the sinker nose is a ground parallel to the sinker jaw. On the downward horizontal plane, the aforementioned sinker jaw has: a first sinker jaw, which is an upward horizontal plane facing parallel to the lower surface of the aforementioned sinker nose below the lower surface of the aforementioned sinker nose; The second sinker jaw is an upward horizontal plane having the same height as the first height, which is the height of the first sinker jaw, and is formed to be separated from the first sinker jaw in the forward direction; the first transition surface , which is connected to the front end of the first sinker jaw, and is different from the first sinker from a first height, which is the height of the first sinker jaw, to a height lower than the lower surface of the nose of the first sinker. and a second transition surface that transitions forward from the second height to the first height, and the front end is connected to the second sinker jaw.

A sinker generally used in a single jersey circular knitting machine has a thin plate shape, and consists of a sinker base having a lower surface of the sinker base as a downward horizontal plane, a sinker butt protruding upward from the rear of the sinker base, and The sinker front part is formed upward and forward from the front upper end of the sinker base. In the front part of the sinker, a sinker nose is formed at the uppermost part. The sinker nose has a shape that protrudes forward. Below the nose of the sinker, a sinker jaw is formed spaced apart from the nose of the sinker. Such a typical sinker is essentially a horizontal plane with the jaws of the sinker upward. In addition, the entire sinker jaws have substantially the same height. In addition, substantially the sinker jaws face parallel to the lower surface of the sinker nose.

In the present invention, the sinker system sinker nose is composed of the upper surface of the sinker nose, the lower surface of the sinker nose, and the transition surface of the sinker nose. The lower surface of the sinker nose is a downward horizontal plane. The sinker nose transition surface is bound in the vertical direction (height direction) within the height range below the height of the upper surface of the sinker nose and above the height of the lower surface of the sinker nose, and is formed between the upper surface of the sinker nose and the height of the lower surface of the sinker nose. Between the undersurface of the nose of the sinker. In the up-down direction, up means high and down means low.

Moreover, in this invention, a sinker jaw has a 1st sinker jaw at the back, and has a 2nd sinker jaw at the front. The first sinker jaw and the second sinker jaw are upward horizontal planes. The first sinker jaw and the second sinker jaw have the same height as a whole and are the first height. The first sinker jaw faces parallel to the lower surface of the sinker nose. Between the first sinker jaw and the second sinker jaw are formed a first transition surface that transitions forward to a second height different from the first height, and a first transition surface that transitions forward from the second height to the first height The second transition surface of the transition. The second height is lower than the height of the lower surface of the nose of the sinker.

The sinker for plated jacquard knitting of the present invention is characterized by having a sinker base having a lower surface of the sinker base as a downward horizontal plane, and a sinker butt protruding upward from the rear of the sinker base; The front part of the sinker is formed from the upper and front of the front of the base of the sinker; the nose of the sinker is formed at the uppermost part of the front part of the sinker, and the nose of the sinker is formed by the upper surface of the nose of the sinker, as the direction of the sinker. The lower surface of the sinker nose of the lower horizontal plane, and the sinker nose transition surface formed between the upper surface of the sinker nose and the lower surface of the sinker nose with a height above the height of the lower surface of the sinker nose; The first sinker jaw is an upward horizontal plane facing parallel to the lower surface of the sinker nose; the sinker throat transition surface is formed on the lower surface of the sinker nose and the first sinker jaw. between; the second sinker jaw, which is an upward horizontal plane of the same height as the aforementioned first sinker jaw; the first transition surface, which is from the height of the aforementioned first sinker jaw toward the sinker nose and a second transition surface that transitions forward from the aforementioned second height to the height of the second sinker jaw.

Accordingly, the heights of the first sinker jaw and the second sinker jaw are the first height, the first transition surface transitions from the first height to the second height and forward, and the second transition surface transitions from the second height to the first height. a height and transition forward. The front end of the first sinker jaw is connected to the rear end of the first transition surface, and the front end of the second transition surface is connected to the rear end of the second sinker jaw. Therefore, the front end of the first sinker jaw, which is the first height, passes through the rear end of the first transition surface, which is the first height, to the front end of the first transition surface, which is the second height. In addition, the rear end of the second transition surface which is the second height passes through the front end of the second transition surface which is the first height to the second sinker jaw which is the first height.

In the sinker of the present invention, the upper surface of the sinker nose may be an upward horizontal plane, and the above-mentioned sinker nose transition surface may be a height below the upper surface of the sinker nose.

According to this structure, the sinker nose transition surface is formed in a region of a height lower than the height of the upper surface of the sinker nose and higher than the height of the lower surface of the sinker nose. Therefore, the sinker nose transition surface does not have a portion where the height of the sinker nose transition surface is higher than the height of the upper surface of the sinker nose or lower than the height of the lower surface of the sinker nose. Thereby, the sinker does not have a level difference on the upper surface of the sinker nose or the lower surface of the sinker nose like the sinker for double pile knitting and the sinker for terry knitting, for example. The upper surface of the sinker nose is an upward horizontal plane, which is also the same height, and there is no part where the height changes in the middle.

The sinker of the present invention is characterized in that a third sinker jaw is formed between the first transition surface and the second transition surface, the front and rear ends of which are located at the second height as an upward horizontal surface.

The first transition surface and the second transition surface are inclined surfaces, curved surfaces, etc. inclined in opposite directions. In the present invention, each sinker is controlled so that the first transition surface or the second transition surface is brought close to the knitting needle. Thereby, the first transition surface and the second transition surface are located on the front side of the knitting needle. In cases where the control of the sinker cannot be finely set, it is desirable that the first transition surface and the second transition surface are set to be slightly separated. Therefore, it is preferable to provide a third sinker jaw whose front and rear ends belong to the second height between the first transition surface and the second transition surface. The front end of the third sinker jaw and the rear end of the second transition surface are connected without a step, and the rear end of the third sinker jaw and the front end of the first transition surface are connected without a step. The heights of the rear end of the second transition surface and the front end of the first transition surface are both the second height, so the heights of the front and rear ends of the third sinker jaws only need to be the second height. There is no problem with the shape between the two ends, but an upward horizontal plane that does not easily affect the formation of the coil is preferable. At this time, a protrusion is formed on the sinker jaw by the first transition surface, the second transition surface, and the third sinker jaw. Preferably, the entire third sinker jaw is located lower than the lower surface of the sinker nose. If it is higher than the lower surface of the sinker nose, a protrusion larger than the sinker throat is formed on the sinker jaw among the first transition surface, the third sinker jaw, and the second transition surface. Thereby, when the coil exceeds the protrusion, there is a possibility that a bad influence may be caused by contact.

In the above invention, it is preferable that the nose of the sinker protrudes from the rear toward the front above the first transition surface, and the front end of the nose of the sinker is formed to be positioned rearward of the front end of the first transition surface.

Preferably, the sinker is selected on the first rail and the rear in the front-rear direction is the lower direction of the first transition surface. In the knitting process, the first transition surface is located on the front side of the knitting needle, and when the hook of the knitting needle is lowered to the vicinity of the sinker nose, the front end of the sinker nose is located within the range in the front-rear direction of the first transition surface. When viewed from the tangential direction of the circle of the needle cylinder of the circular knitting machine, the front end of the sinker nose enters from the rear end to the front in the hook of the knitting needle and is close to the knitting needle, but does not overlap, and will be separated from the sinker A space connecting the space above the upper surface of the nose to the space lower than the lower surface of the sinker nose can be formed between the sinker nose transition surface and the knitting needle. Thereby, a forward guide path of the first thread that is fed upward is formed in the hook. In this way, the first thread is more reliably guided forward of the second thread through the guide path as the hook is lowered. There is no load on the line such as being pressed by the sinker, and the possibility of reverse rotation can be reduced.

In addition, the sinker of the present invention may be provided with a selection portion at a position rearward of the sinker base portion.

According to this structure, the operation rail of each sinker can be selected as any one of the first rail and the second rail by receiving the action of the sinker selection device by the selection unit. [Effect of invention]

According to the present invention, in the plating knitting of the circular knitting machine, the operation track of each sinker is selected to be either the first track or the second track during the operation of the circular knitting machine, so that the sinker can be used. The first transition surface or the second transition surface exchanges the position of the first thread and the position of the second thread in the hook of each knitting needle. Moreover, since the sinker is one type, there is no need to increase the type and to spend extra cost. In addition, it can meet the requirements of knitting of fabrics with finer gauge. Furthermore, it is possible to provide a knitting mechanism in which the first thread and the second thread are difficult to reverse, and a sinker used for the knitting mechanism.

[Form for carrying out the invention] [Example 1]

Hereinafter, the content of the present invention will be described using specific examples, but the present invention is not limited to these examples.

In the present example, the plated jacquard knitting was performed using the single jersey circular knitting machine M as shown in FIG. 1 . FIG. 2 shows a cross-sectional view of the periphery of the braided portion of the present embodiment. The single jersey circular knitting machine M has the same structure as a conventional general circular knitting machine. The single jersey circular knitting machine M includes a needle cylinder 9 that accommodates the knitting needles 8 , and a sinker dial 10 that accommodates the sinkers 1 . The knitting needle 8 moves up and down, and the sinker 1 moves horizontally back and forth in a manner orthogonal to the knitting needle 8 . The knitting needle 8 rotates the needle cylinder 9 in which the knitting needle 8 is accommodated by the power from the drive motor, and the butt 83 of the knitting needle is guided by the needle cam 91 fixed to the circular knitting machine to move up and down. Similarly, the sinker dial 10 accommodating the sinker 1 is rotated in synchronization with the needle cylinder 9, whereby the sinker 1 is guided by the sinker cam 101 fixed to the circular knitting machine to move back and forth. Then, the thread is supplied from the thread guide 12 to the knitting needle 8, the knitting needle 8 descends from the sinker jaw 4 (FIG. 3), and when the knitting needle 8 bends the thread (reaches the lowest point of the motion track), it passes the thread span. A stitch is formed through the hook 81 of the knitting needle 8 and the sinker jaw 4 of the sinker 1 adjacent to the knitting needle 8 . The sinker 1 in the present invention has a thin plate shape like the sinker 1 of a general single jersey circular knitting machine, and has a sinker base having a lower surface of the sinker base as a downward horizontal plane, and a sinker base from the sinker base. The sinker butt 102 ( FIG. 2 ) protruding rearward and upward, and the sinker front portion 2 integrally formed upward and forward from the front upper end of the sinker base portion.

FIG. 3 shows an enlarged side view of the sinker 1 of Embodiment 1 of the present invention. In the sinker front part 2, the sinker nose 3 is formed in the uppermost part. The sinker nose 3 has a shape protruding forward. Below the sinker nose 3 , a sinker jaw 4 is formed at an interval from the sinker nose 3 . Like a general sinker, the sinker jaw 4 is an upward horizontal plane. In addition, like a general sinker, the whole sinker jaw 4 has the same height. In addition, like a general sinker, the sinker jaw 4 faces the lower surface of the sinker nose 3 in parallel. Each part is not formed by joining independent parts, but integrally formed.

In the sinker 1 of the present invention, the sinker nose 3 is composed of the sinker nose upper surface 31 and the sinker nose lower surface, like the sinker for a raceway of a general circular knitting machine for single jersey. The surface 33 and the nose transition surface 32 of the subsidence sheet are formed. In addition, the sinker nose upper surface 31 is an upward horizontal plane. The sinker nose lower surface 33 is a downward horizontal plane.

The shape of the sinker 1 of the circular knitting machine M of the present embodiment is only one type. In the sinker 1 of the present embodiment, the sinker jaw 4 has a shape in which protrusions are formed. A first transition surface 42 and a second transition surface 43 are formed on the protrusion. The first transition surface 42 is an inclined surface in the forward direction. The second transition surface 43 is a forward downward inclined surface. Furthermore, the first sinker jaw 41 is provided at a position rearward of the protrusion of the sinker jaw 4 . Moreover, the 2nd sinker jaw 44 is provided in the position ahead of the protrusion of the sinker jaw 4. As shown in FIG. The first sinker jaw 41 and the second sinker jaw 44 are upward horizontal surfaces. In addition, the entire first sinker jaw 41 and the second sinker jaw 44 have the same height (referred to as "first height"). In addition, a third sinker jaw 45 is formed between the first transition surface 42 and the second transition surface 43 . In this embodiment, the third sinker jaw 45 is an upward horizontal plane. The entire third sinker jaw 45 has the same height (referred to as "second height"). The second height is a different height from the first height. In this embodiment, the second height is higher than the first height. The first sinker jaws 41 are opposed to the lower surface 33 of the sinker nose in parallel. The sinker throat is formed by the sinker nose lower surface 33, the first sinker jaw 41, and the sinker throat transition surface 34 formed between the sinker nose lower surface 33 and the first sinker jaw 41 . Between the first sinker jaw 41 and the second sinker jaw 44 is formed a second height from the front end of the first sinker jaw 41 via the first height of the rear end to the second height of the front end which is different from the first height. The first transition surface 42 that transitions from the rear to the front. In addition, a second transition surface 43 is formed which transitions from the second height of the rear end to the first height of the front end, and then to the rear end of the second sinker jaw 44 and from the rear to the front. The second height is lower than the height of the lower surface 33 of the sinker nose. This is because if the height is equal to or higher than the lower surface 33 of the sinker nose, the protrusion on the sinker jaw has a shape that blocks the sinker throat, and there is a high possibility of obstructing the movement of the wire. The angle between the first transition surface 42 and the first sinker jaw 41 is equal to the angle between the second transition surface 43 and the second sinker jaw 44 . Therefore, the inclination angle of the first transition surface 42 relative to the horizontal is the same as the inclination angle of the second transition surface 43 relative to the horizontal. Thereby, the size of the coil formed by the first transition surface 42 and the second transition surface 43 is substantially the same.

The first transition surface 42 and the second transition surface 43 are straight inclined surfaces. However, in the present invention, the first transition surface 42 or the second transition surface 43 may be a curved surface. As long as it is not a horizontal plane, the object of the present invention can be achieved.

In the height direction, which is the vertical direction, the sinker nose transition surface 32 does not have a portion lower than the height of the sinker nose lower surface 33 . This reduces the possibility of reversal by transmitting as little extra motion to the line as possible. In addition, the sinker nose transition surface 32 does not have a portion higher than the height of the sinker nose upper surface 31 . In the present invention, for example, the sinker nose transition surface 32 may be made higher than the sinker nose upper surface 31 in order to easily guide the plating yarn. However, for example, the sinker is not a pile fabric or a sinker for loops. That is, it is not a sinker with a plurality of steps on the upper surface of the nose of the sinker like a pile fabric or a sinker for loops. The upper surface of the sinker nose is preferably constituted by a horizontal plane.

In addition, in this embodiment, on the lower surface 33 of the sinker nose, the first sinker jaw 41, and the second sinker jaw 44, there are no belts such as pile fabric and sinkers for loops. sloping part. The sinker throat transition surface 34 is formed in a range from the height of the aforementioned sinker nose lower surface 33 to the aforementioned height of the first sinker jaw 41 . Thereby, the sinker throat has a straight shape. However, in the present invention, the sinker throat transition surface may have, for example, a portion higher than the height of the sinker nose lower surface 33 and a portion lower than the sinker jaw 41 .

4 is an operation line diagram showing an operation trajectory of the knitting needle and the sinker of Example 1. FIG. Plating jacquard knitting is performed by the repetition of the first supply path 1F and the second supply path 2F. The needle cam 91 ( FIG. 2 ) has different tracks in the first supply path 1F and the second supply path 2F. As a result, the movement trajectory 5 of the knitting needles 8 in the first supply path 1F is different from the movement trajectory 5 of the knitting needles 8 in the second supply path 2F. The needle cams 91 are provided with the same needle cams 91 for every two supply paths. That is, the movement orbits of the knitting needles 8 in every two supply paths are the same. Thereby, all the knitting needles 8 repeat the operation trajectories of the first supply path 1F and the second supply path 2F by repeating the two supply paths.

The sinker cams 101 ( FIG. 2 ) have different operating orbits in the first supply path 1F and the second supply path 2F, and the first supply path 1F uses the same sinker cam 101 to allow all the sinkers 1 to select the same operation orbit 6 . In the second supply path 2F, the sinker 1 selects two operating rails of the first rail 61 and the second rail 62 .

In this embodiment, in order to prevent reverse rotation, the plated jacquard knitting using two supply paths is performed. The ground wire 72 (second wire) is supplied to the knitting needle 8 in the first supply path 1F. The track first raises the knitting needle 8 to release the old loop from the hook 81 (FIG. 5), then descends, supplies the ground wire 72 and inserts it into the hook 81 of the knitting needle, and then advances the sinker 1 to remove the ground wire 72 into the sinker throat. Then, in the second supply path 2F, the knitting needles 8 are raised again, and the plated yarns 71 (first yarns) are supplied to the knitting needles 8 . At this time, since the ground wire 72 is pressed by the lower surface of the sinker nose and does not rise, the ground wire 72 remains in the vicinity of the sinker throat.

Then, any one of the first track 61 and the second track 62 is selected for the motion track 6 of the sinker 1 . The sinker 1 of the first rail 61 serves as an operating rail in which the first transition surface 42 is located at the position of the front side surface of the knitting needle 8 . This maintains a slightly forward position than the position of the sinker 1 on the second rail 62 . In this way, the first transition surface 42 becomes the position closest to the knitting needle 8 during the descending process of the knitting needle 8 . Then, the knitting needle 8 passes through the front side of the first transition surface 42 and reaches the lowest point (yarn bend) in the movement track 5 of the knitting needle 8 . The sinker 1 of the second rail 62 is an operating rail in which the second transition surface 43 is positioned on the front side of the knitting needle 8 . This maintains a slightly rearward position than the position of the sinker 1 on the first rail 61 . In this way, the second transition surface 43 becomes the position closest to the knitting needle 8 during the descending process of the knitting needle 8 . Then, the knitting needle 8 passes through the front side of the second transition surface 43 and reaches the lowest point in the movement track 5 of the knitting needle 8 . Thereby, the old stitches are separated from the knitting needles, and the plated stitches formed by the first supply path F1 and the second supply path F2 are formed. In this embodiment, the knitting needles are all knitted, and all the knitting needles take the same motion trajectory in the repetition of the two supply paths. However, not all loops may be formed, but general tucks may be knitted, and a float pattern may be added. In this case, the tuck track T and the float track W are selected for a part of the knitting needles, but the movement tracks of the knitting needles other than the portion where the track changes during the stitching, tuck, and float are all the same.

5 is a schematic diagram showing the position of the thread in the hook 81 when the knitting needles 8 on (A) the first rail 61 and (B) the second rail 62 of the sinker 1 of the first embodiment are lowered. The inside of the hook 81 is generally an area surrounded by the hook 81 and the latch 82 of the knitting needle 8 .

In the first rail 61, the ground wire 72 is guided to the lower side, that is, to the rear. In addition, the plated yarn 71 is positioned forward of the ground wire 72 . Thereby, in the 1st rail 61, as shown in (a3) of FIG.

In the present invention, the ground wire 72 is brought into contact with the first transition surface or the second transition surface at a point earlier than the plating yarn 71, and is guided to the lower side of the first transition surface or the second transition surface. Then, the plated yarn 71 is guided into the hook 81, and the knitting needle is lowered so that the plated yarn comes into contact with the first transition surface or the second transition surface, and is drawn to the lower one of the first transition surface or the second transition surface. One side guides. Depending on the timing at which the line is guided to the first transition surface or the second transition surface, control can be performed without inverting each line.

In the present embodiment, during the vertical movement of the knitting needle 8, the sinker 1 starts to descend from the knitting needle 8, and as shown in FIG. Position of sinker nose 3. Above the first transition surface, the front end of the sinker nose 3 is located rearward of the front end of the first transition surface. Therefore, when the plating yarn 71 descends, a guide path that is automatically guided forward is formed in the hook 81 through the sinker nose transition surface 32 . Then, as shown in FIG. 5( a2 ), the plated yarn 71 is guided forward and the ground wire 72 is guided backward through the guide path, and the possibility of inversion is reduced by separating the distance between the two.

On the other hand, the second transition surface 43 is an inclined surface with a low front and a high back, and in the second rail 62 , as shown in FIG. 5( b2 ), the ground wire 72 is guided lower and forward. In addition, the plating yarn 71 is positioned behind the ground wire 72 . Thereby, in the 2nd rail 62, as shown in (b3) of FIG. 5, it becomes a plated knitting in which the ground wire 72 is located in the front and the plated yarn 71 is located in the rear.

In this way, by selecting either the first rail 61 or the second rail 62 for the operation rail 6 of the sinker 1 for each sinker 1, the positions of the ground wire 72 and the plating thread 71 can be exchanged. In the operation of the sinker 1 and the knitting needle 8, after the knitting needle 8 catches the thread, the sinker 1 moves so that the first transition surface 42 or the second transition surface 43 of the sinker 1 is located on the front side of the knitting needle. During this operation, the speed of the sinker 1 and the knitting needle 8 does not change slightly or move in the opposite direction, and moves smoothly. At a roughly constant speed, little load is applied to the wire. Then, the knitting needle 8 descends to the lowest point (bending) of the motion track. During this operation, the sinker 1 is also stationary, and the speed of the knitting needle 8 does not change slightly or moves in the opposite direction, but smoothly descends. In this operation, the knitting needle 8 is also at a substantially constant speed, and the sinker 1 does not move until the yarn is bent. By such a reasonable operation, the possibility of reversal of the lines can be reduced.

In this embodiment, a sinker selection device is used. Moreover, a selection part is provided in the position behind a sinker base part. A sinker selection device is provided above the selection portion. With this sinker selection device, the selection unit is acted upon by the sinker selection device, and can select either the first rail 61 or the second rail 62 for the operating rail 6 of each sinker. Thereby, the positions of the ground wire 72 and the plated yarn 71 can be exchanged, and the plated jacquard knitting can be performed.

It should be noted that the present invention is not limited to this embodiment. For example, although the protrusion on the sinker jaw 4 is trapezoidal in this embodiment, even if it is a triangle or a semicircle, it certainly falls within the scope of the present invention. In addition, for example, the structure of the present invention is to perform a plated jacquard knitting place for exchanging the positions of the plated yarn 71 (first yarn) and the ground yarn 72 (second yarn) in the plating knitting during the operation of the circular knitting machine. It can be seen that the required structure, even if an arrangement corresponding to the type of the woven fabric is added thereto, also belongs to the scope of the right of the present invention. For example, the knitting needles 8 can also be selected by a general knitting needle selection device to form stitches, tucks, and float. With the needle selection device, the variety of fabrics that can be further knitted is enriched. In the present invention, the position of the sinker when the knitting needle is lowered to the lowest point is important, and the selection of stitching, tucking and floating thread does not affect the position of the sinker, so even if there is no knitting needle selection device, it still belongs to the scope of rights of the present invention .

In addition, even if it does not have the structure described in this Example, it belongs to the right scope of the present invention. For example, in the present invention, when the first transition surface and the second transition surface are directly connected, the third sinker jaw 45 may not be provided.

In addition, in the structure of this invention, even if it adds the change which does not affect the plating jacquard knitting of this invention, for example, even if it provides meaningless grooves or protrusions, it certainly belongs to the right scope of this invention. [Example 2]

FIG. 6 is an operation diagram showing an operation path of the sinker 1 and the knitting needle 8 of the second embodiment. In this embodiment, plated jacquard knitting is performed by one supply path. In this example, the possibility of reversal is higher than that of Example 1, but the number of stitches is increased, so it is useful when it is desired to increase the yield of fabrics under conditions such as threads and patterns that are difficult to cause reversal.

In the present embodiment, all the knitting needles 8 in all supply paths move up and down on the same movement track 5A. In the present embodiment, the plated yarn 71A is supplied to the knitting needle 8 from a position higher than the ground line 72A of the needle movement track. The ground wire 72A is supplied to the knitting needle 8 from a position lower than the plating yarn 71A. The sinker 1 (the same structure as in FIG. 3 of the first embodiment) is pulled backward after the knitting needle 8 is raised, and the ground wire 72A is supplied to the vicinity of the sinker jaw 4 . Then, the second thread is put into the sinker throat that advances the sinker. In addition, the operating orbit of the sinker 1 is divided into a first orbit 61A and a second orbit 62A. In the first rail 61A and the second rail 62A, the same line positions as in FIG. 5 can be selected to exchange the positions of the lines. [Example 3]

FIG. 7 is a side view of the sinker 1B of Example 3. FIG. In the present embodiment, the recessed portion 45B is not formed on the sinker blade jaws 4 and 4A as in the previous embodiments 1 and 2, but the projections are formed. The sinker jaw 4B has the first sinker jaw 41B in the rear and the second sinker jaw 44B in the front with the recessed portion 45B interposed therebetween. The recessed portion 45B has a first transition surface 42B that transitions forward from the first height of the front end of the first sinker jaw 41B to the second height lower than the first height. Moreover, it has the 2nd transition surface 43B which transitions forward from the 2nd height to the rear end of the 2nd sinker jaw 44B which is the 1st height. Furthermore, a third sinker jaw 45B is formed between the first transition surface 42B and the second transition surface 43B. The entire third sinker jaw 45B is an upward horizontal plane of the second height.

Fig. 8 shows (A) the first rail 61A and (B) the second rail 62A when the sinker 1 of the embodiment 1 is used and the sinker 1 is changed to the sinker 1B of the embodiment 3 Schematic diagram of the position of the thread in the hook 81 when the knitting needle 8 is lowered. In this embodiment, the inclinations of the first transition surfaces 42B and the second transition surfaces 43B are inclined in the opposite direction to the inclinations of the first transition surfaces 42 and 42A and the second transition surfaces 43 and 43A in the first and second embodiments. Therefore, the position of the wire on each operating track of the sinker 1B is the position opposite to the position of the wire in Examples 1 and 2. In addition, in the present embodiment, when approaching the first track of the first transition surface 42B, it is not the position where the fin nose 3B enters the needle hook 81 as in the first and second embodiments, and is not formed in the needle hook 81 A guide path for guiding the plated yarn forward by the sinker nose 3B.

The present invention is not limited to these Examples. As long as the technical idea represented by the technical solution is satisfied, even if there is a slight difference in structure, it belongs to the technical scope of the present invention.
