Description

  The present invention relates to a knitting fabric cam device that is mounted on a carriage that reciprocates along a needle bed of a flat knitting machine and selectively knitting drives composite needles arranged on the needle bed.

  Conventionally, in a flat knitting machine equipped with needle beds before and after the mouth, a rib structure or the like is knitted between the front stitches on one needle bed and the back stitches on the other needle bed, A cylindrical knitted fabric can be knitted by supplying the needle bed so as to go around. In each needle bed, a large number of knitting needles are arranged at a constant pitch along the tooth opening, and each knitting needle advances and retracts to the tooth opening by selective driving by a knitting fabric cam device mounted on the carriage. The operation for knitting is performed.

  FIG. 6 shows an example of the configuration of a conventional knitted fabric knitting cam device 101 as a cam arrangement as viewed from the side facing the needle bed (for example, see Patent Document 1). The configuration of the knitting fabric cam device 101 is based on that shown in FIG. When the tubular knitted fabric 1 is knitted at the mouth 2, the knitting yarn so that the front knitted fabric knitted by the front needle bed F and the rear knitted fabric knitted by the rear needle bed B are connected on both sides of the knitting width. Only the cylindrical knitted fabric 1 having a flat knitted structure can be knitted only by turning the knitted. If the transfer between the front and back needle beds is included, the tubular knitted fabric 1 including the rib structure and the like can be knitted. Furthermore, a composite needle in which a needle body and a slider are combined can be used as a knitting needle.

  The knitting fabric cam device 101 includes a needle body cam 10, a slider cam 11, and a slider cam 11 that are mounted on carriages 103 and 104 provided on the front needle bed F and the rear needle bed B that face each other across the mouth 2. A needle selection mechanism 12 and the like are included. Each cam is provided on the surface of the ground plate where the carriages 103 and 104 face the needle bed, and protrudes from the surface of the ground plate to the needle bed side. The cross hatched surface is an inclined surface that continuously connects the surface of the main plate and the protruding cam surface.

  As disclosed in FIGS. 2 and 3 of Patent Document 1, the compound needle has a needle body and a slider that are relatively displaceable, and a tongue at the tip of the slider opens and closes a hook at the tip of the needle body. Then, the tongue of the slider is advanced to the tooth opening 2 rather than the hook to transfer and hold the stitches. In order to efficiently perform operations relating to transfer and stitch holding using a slider, it is necessary to divide the tip portion including the tongue of the slider into two branches so as to sandwich the hook. The knitting needle is accommodated in a needle groove formed in the needle bed, and a needle jack, a select jack, a selector, and the like are sequentially combined in a portion on the side away from the tooth mouth 2. The needle jack is connected to the tail portion of the needle body, and a bat protruding from the needle jack to the surface side of the needle groove receives the action of the needle body cam 10 to drive the needle body. The slider also has a butt that protrudes from the needle groove and receives the action of the slider cam 11.

  The needle selection mechanism 12 includes a needle selection actuator 13 that acts on a selector provided on the tail end side of each knitting needle, a selector lifting cam 14, a selector push-up cam 15, and a selector guide cam 16. The selector levitation cam 14 moves around to the bottom surface side of the needle groove at the tail end of the needle bed, and acts to float the tail portion of the selector in the needle groove. When the selector floats in the needle groove, the knitting needle is selected. When the needle selection actuator 13 presses the selection butt of the selector, the selector sinks into the needle groove and enters a non-selected state. The selector is provided with bats on the tail end side and the tip end side, and the selector push-up cam 15 acts on the butt on the tail end side in a selected state. A selector guide cam 16 acts on the butt on the tip side of the selector.

  As a result of the needle selection by the needle selection mechanism 12, the knitting operation can be selected within a range prepared for each knitting needle by changing the guide path of the bat in the knitting cam 20. The knitting cam 20 includes a lasing cam 21, a guard cam 22, crests 23 and 24, rubber crests 25 and 26, and a movable presser 30. In the rising cam 21, the inclined ascending cam surface that raises the butt of the needle jack to the side of the tooth opening 2 is movable and appears and disappears with respect to the main plate. A guide path formed between a fixed portion at the center of the raising cam 21 and the guard cam 22 advances the needle body to the tooth opening 2 to the knit position. The crests 23 and 24 are movable in the extending direction of the inclined cam on the side of the guard cam 22, and the amount of the hook that is supplied with the knitting yarn at the tooth opening 2 can be adjusted. The rubber piles 25 and 26 are movable and can be used for inlay knitting where the elastic yarns are inserted by appearing and protruding from the main plate. The movable presser 30 acts on the bat of the select jack and can be pressed to sink the select jack into the needle groove. When the select jack is submerged in the needle groove, the butt of the needle jack is not affected by the knitting cam 20.

  For needle selection in the knitting fabric cam device 101, the select jack half lowering cams 31, 32, the select jack lowering cams 33, 34, and the select jack presser 35, together with the needle selection mechanisms 12 arranged on both sides of the knitting cam 20, are shown. Is also used. The select jack lowering cams 33 and 34 are movable, and appear and disappear from the main plate.

  The knitting fabric cam device 101 has a single cam configuration for the knitting cam 20, but includes a transfer cam group 110 and a stitch receiving cam group 120 for enabling transfer. Each knitting knitting cam device 101 has a transfer cam group 110 on the downstream side of the knitting cam 20 and a upstream cam group 110 on the upstream side with respect to the movement of the carriages 103 and 104 in the forward direction indicated by the arrows on the tubular knitted fabric 1. Each has a receiving cam group. Between the front and rear carriages 103 and 104, the transfer cam group 110 and the eye-receiving cam group 120 are arranged so as to face each other with the tooth opening 2 interposed therebetween.

  The transfer cam group 110 includes a transfer side slider raising cam 41, a transfer side stitch receiving cam 43, and a slider transfer cam 111. The transfer-side slider raising cam 41 and the transfer-side stitch receiving cam 43 are respectively movable and appear and disappear from the main plate. The slider transfer cam 111 is formed with a cam route 111 a that maintains a state in which the slider that holds the stitch on the tongue advances into the tooth opening 2.

  The eye receiving cam group 120 includes an eye receiving side stitch receiving cam 51, an eye receiving side holding lasing cam 52, and an eye receiving slider cam 121. The eye receiving side stitch receiving cam 51 and the eye receiving side holding lasing cam 52 are respectively movable, and appear and disappear from the main plate. A cam route 121 a is formed in the eye-receiving slider cam 121 for continuing the state in which the stitch is held by the slider that has advanced to the tooth opening 2. The eye-receiving cam group 120 also includes a needle jack guide cam 122 and a hold presser 123.

  FIG. 7 shows a function switching state performed when a tubular rib structure is knitted by the knitted fabric knitting cam apparatus 101 of FIG. The function is switched by controlling a movable cam or presser. In the knitting fabric cam device 101, the front carriage 103 can be transferred by the transfer cam group 110 when the left line is in the forward direction, and by the eye receiving cam group 120 when the right line is in the reverse direction. Eye catching is possible. The rear carriage 104 can be moved by the transfer cam group 110 when the right line is in the forward direction, and can be received by the eye cam group 120 when the left line is the reverse direction. Therefore, the transfer from the front to the rear is performed on the left side, and the transfer from the back to the front is performed on the rear side of the knitting cam 20 in the right direction.

  Thereafter, the tubular knitted fabric 1 having a rib structure is knitted for one course by the movement of the carriages 103 and 104 for ten courses c1 to c10. Before the start of the course c1, the front and back needle beds are in a state in which the back stitches of the rib structure knitting the stitches in each needle bed are also locked. In addition, empty needles are provided so that the back stitches locked by the opposing needle beds can be transferred in the needle knitting knitting.

  In the first course c1, on the left side of the front and rear carriages 103, 104, the back stitch that is locked by the front needle bed is transferred to the rear needle bed. The next course c2 is an empty course, and the carriage reverses and moves right. On the left side of the next course c3, knitting K for the front stitch is performed on the front needle bed and knitting k for the back stitch is performed on the rear needle bed. In the next course c4, on the right side of the carriage, the back stitch knitted on the rear needle bed is transferred to the front needle bed. The next course c5 is an empty course, and the carriage reverses and moves left.

In the next course c6, the back eye locked to the rear needle bed is transferred to the front needle bed on the right line of the carriage. The next course c7 is an empty course, and the carriage reverses and moves left. In the right course of the next course c8, the back stitch knitting k is performed on the front needle bed, and the front stitch knitting K is performed on the rear needle bed. The next course c9 is an empty course, and the carriage reverses and moves left. In the right course of the next course c10, the back stitch knitted on the front needle bed is transferred to the rear needle bed. Thereafter, the courses c1 to c10 are repeated.
Japanese Patent No. 4015982

  As shown in FIG. 7, when knitting a tubular knitted fabric 1 having a rib structure, it is necessary to transfer the front and back stitches. In the knitting fabric cam device 101 as shown in FIG. 6, transfer is possible only in the forward direction with respect to the reciprocating travel of the carriages 103, 104, so only the carriages 103, 104 are moved without any knitting. An empty course to move occurs.

  If cams capable of transferring and catching are arranged on both sides of the knitting cam 20, it is possible to prevent the occurrence of an empty course. However, the configuration of the knitting fabric cam device 101 becomes complicated, leading to an increase in size and weight of the carriages 103 and 104. When the carriages 103 and 104 are increased in size, the space required outside the knitting width to reverse the moving direction increases, and the knitting efficiency particularly when knitting a small knitted fabric with a not very large knitting width is reduced. To do. As the weight of the carriages 103 and 104 increases, the time required for acceleration and deceleration increases, and the knitting efficiency decreases.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a knitted fabric knitting cam device that can eliminate the limitation of transfer due to the moving direction of the carriage without increasing the size and weight of the carriage.

In the present invention, a knitting needle is a compound needle divided into two so that the tip of a slider that can move forward and backward with respect to the hook sandwiches the hook, and a needle bed on which the knitting needles are arranged is opposed to the front and back of the tooth opening. The flat knitting machine is provided on each needle bed and reciprocates to the left and right of the tooth mouth, and is mounted on a carriage in which the left and right sides of the front needle bed and the left and right sides of the rear needle bed are in the forward direction, respectively.

A transfer cam group provided with a guide path that is arranged on the subsequent side of the knitting cam in the forward direction and that causes the knitting needle to perform an operation of moving the stitch to the needle bed side facing the knitting needle;
A knitting cam that is arranged on the front side in the forward direction and includes a guide cam group that includes a guide path that causes the knitting needle to receive a stitch that is moved from the opposite needle bed side by moving in the reverse direction.
Between the front and rear carriages, the transfer cam group and the eye-receiving cam group face each other.
The eye-receiving cam group is a state in which the stitches that are transferred beyond the tooth opening by the action of the facing transfer cam group are received by the hook, and the guide path for the transferring operation is received by the hook and is advanced to the tooth opening by the slider. A holding operation guide path and a mechanism for switching the operation of the knitting needle to any one of the guide paths;
Through the knitting cam, the transfer cam group and the eye receiving cam group, there is provided a guide path for continuing to maintain the state in which the slider advances to the tooth opening and holds the stitch with respect to the movement in both the left and right directions,
For each carriage, a slider for switching whether or not to guide the slider, which has advanced into the tooth opening by the knitting cam, to the guide path for continuation, is moved between the knitting cam and the eye catching cam group. The transfer lasing cam is arranged,
When the carriage moves in the reverse direction, the slider transfer lasing cam guides the slider to the continuation guide path so that the slider holding the stitches has advanced to the tooth opening.
Knitted fabric knitting cam characterized in that when moving in the forward direction after carriage reversal, the stitch held by the slider is moved to the knitting needle that operates by the action of the opposing transfer cam group over the tooth opening Device.

  Further, according to the present invention, during the forward movement after the reversal, the stitches are driven so that the stitches are knitted by the knitting cam on the trailing side of the eye receiving cam group, and the stitches are also formed by the knitting cams on the opposite carriage. It is characterized by being driven to form.

  In the opposite carriage of the present invention, the knitting needles to which the stitches are transferred are driven so that the stitches following the stitches are knitted.

  According to the present invention, when the carriage moves in the forward direction, it is possible to transfer from the transfer cam group to the opposite needle bed side cam group. When the carriage moves in the reverse direction, the slider transfer lasing cam guides the slider to the guide path for continuation so that the slider holding the stitches is advanced to the tooth opening. When moving in the direction, the stitches can be transferred to the knitting needles that operate by the action of the transfer cam group facing each other. By adding a slider transfer lasing cam, it is possible to eliminate the limitation of transfer due to the moving direction of the carriage without increasing the size and weight of the carriage.

  Further, according to the present invention, stitches can be knitted in the same stroke of the carriage following transfer, so that the knitting cam can be used effectively.

  FIG. 1 shows a schematic configuration of a knitted fabric knitting cam device 201 formed on a base plate of a carriage 200 as an embodiment of the present invention. Like the carriages 103 and 104 in FIG. 5, the carriage 200 is provided on each of the needle beds facing each other across the tooth opening 2, but only one of them is shown. Parts of the knitting fabric knitting cam device 201 corresponding to the knitting fabric knitting cam device 101 are denoted by the same reference numerals, and redundant description is omitted. The knitting fabric knitting cam device 201 also assumes that the front needle bed F side of the tubular knitted fabric 1 in FIG. 6 is knitted with the left row of the carriage 200 and the rear needle bed B side is knitted with the right row of the carriage 200. The forward direction and the reverse direction are set in the same manner as the knitting fabric cam device 101. Therefore, the operation described in Patent Document 1 for the knitted fabric knitting cam device 101 can be similarly executed by the knitted fabric knitting cam device 201.

  The knitting fabric cam device 201 includes a slider guide cam 202 on the slider cam 11. The slider guide cam 202 acts on the slider bat with substantially the same phase as the knitting cam 20 acts on the needle jack butt. The slider guide cam 202 is provided with a cam route 202 that communicates with a cam route 121 a for continuing the holding of the eye-receiving slider cam 121. A movable slider transfer lasing cam 241 is provided that faces the position where the guide path of the slider bat branches off at the cam route 202a, and moves in and out of the main plate. The slider transfer raising cam 241 is the same as the slider transfer raising cam 41 disposed between the knitting cam 20 and the slider transfer cam 111.

  FIG. 2 shows an operation in which the knitting fabric cam device 201 shown in FIG. The front and rear carriages 200F and 200B indicate the bat on the tail end side of the slider, the needle jack, the select jack, and the selector as shown by the trajectories 300F, 300B, 301F, 301B, 302F, 302B, 303F, and 303B, respectively, at the right side 200R. Guide you through a simple route.

  In the front carriage 200F, as shown by a trajectory 303F, the tail end side butt of the selector is raised by the raising cam surface 15a by needle selection by the needle selection actuator 13a on the leading side. Although the butt of the select jack passes through the A position where the movable presser 30 is provided, as shown by the trajectory 302F, all the movable pressers 30 are kept in a sunk state. When the rising cam surface of the raising cam 21 is protruded, the butt of the needle jack is guided to abut on the rising cam surface and ascend toward the tooth opening 2 as shown by a locus 301F. By the time the needle jack butt descends from the tooth mouth 2 at the ridge 24, the slider also rises to the tooth mouth 2, as shown by the locus 300F of the slider bat, and remains in the raised state even when the needle body is lowered. The stitches are transferred from the hook of the same knitting needle to the tongue of the slider and held. The slider bat is guided by the slider transfer lasing cam 241 to the cam route 121a for continuing the holding of the eye receiving guide cam 121, and remains in the tooth opening 2 while holding the stitch.

  In the rear carriage 200B, the selector is selected by the needle selection actuator 13a on the subsequent side. Since the selector is in the needle selection state floating in the needle groove, the rising cam surface 15b of the selector push-up cam 15 pushes up the tail end side butt of the selector. When exiting the carriage 200B, the selector guide cam 16 pushes down the butt on the distal end side of the selector, but the selector needle selection state is maintained.

  FIG. 3 shows operations for transferring and forming stitches in the left row 200L of the carriages 200F and 200B following FIG. The front and rear carriages 200F, 200B guide the slider, needle jack, select jack, and butt on the tail end side of the selector so as to pass the paths indicated by the trajectories 310F, 310B, 311F, 311B, 312F, 312B, 313F, 313B, respectively. To do.

  In the knitting needle in which the selector is in the needle selection state before the carriage 200B is reversed in the moving direction shown in FIG. 2, the bats of the slider and the needle jack are transferred as shown in the trajectories 310B and 311B. The cam group 110 is affected. In particular, since the transfer-side eye receiving cam 43 is in a protruding state, the hook of the needle body advances into the tooth opening 2 and the stitch held by the slider of the front needle bed can be received.

  In the front carriage 200F, the eye-sliding slider cam 121 of the eye-receiving cam group 120 acts on the slider that holds the stitches and remains in the mouth 2 in FIG. Withdraw from the mouth 2 to the front needle bed side. While the state in which the slider remains in the tooth opening 2 continues, the hook of the knitting needle that advances from the rear needle bed to the tooth opening 2 enters the tongue that is divided into two branches, and when the slider is pulled to the front needle bed side, The stitch held by the tongue is transferred to the hook of the knitting needle that advances from the rear needle bed to the tooth opening 2.

  Following the above-described operation of transferring the stitch held by the slider on the front needle bed side to the hook of the knitting needle on the rear needle bed side, the needle selection actuator 13b of the front carriage 200F and the needle selection actuator of the rear carriage 200B If each needle is selected at 13a, the stitches can be knitted by the following knitting cam 20 in the same knitting course. Knitting of stitches can be performed in the same manner with knitting needles used for transfer or with knitting needles not used. With the knitting needle that has received the stitch from the slider on the front needle bed side on the rear needle bed side, the stitch following the received stitch can be knitted.

  FIG. 4 shows an operation of transferring a stitch from the front needle bed to the rear needle bed using the knitted fabric knitting cam device 201 of FIG. 1 as a trajectory of the main bat of the compound needle. Slider bat trajectories 350F and 350B and needle jack bat trajectories 351F and 351B by the front and rear carriages 200F and 200B correspond to the operations of the slider and the hook of the needle body, respectively. Select jack butt trajectories 352F and 352B and selector tail end side bat trajectories 353F and 353B by the front and rear carriages 200F and 200B correspond to operations of the select jack and the selector, respectively. If the slider transfer lasing cam 241 is submerged, the substantial configuration is the same as that of the knitting fabric cam device 101 of FIG. Since the slider transfer lasing cam 241 is not related to the locus of the slider bat, it can be raised or lowered. The transfer operation by such a configuration is also described in Patent Document 1 with reference to FIGS. 6 and 7.

  When the front and rear carriages 200F and 200B sandwiching the tooth opening 2 perform the left row 200L that moves to the left in the drawing, the selector selected by the needle selection actuator 13b on the preceding side of the previous carriage 200F is moved to the locus 353F. And is pushed up by the raising cam surface 15a of the selector pushing-up cam 15. The selector is pushed up to the A position where the movable presser 30 is disposed along the locus 352F. Since the movable presser 30 is all in a sunk state and the rising cam surface of the raising cam 21 is in a protruding state, the butt of the needle jack rises toward the tooth opening 2 along the rising cam surface as shown by a locus 351F. It descends from the mouth 2 along the descending cam surface of the ridge 23. The slider bat is guided to advance toward the tooth opening 2 together with the hook of the needle body as shown by a locus 350F, and is then guided to the protruding slider transfer lasing cam 41 to move the slider transfer cam 111. And remains on the side of the mouth 2. At this time, the stitch moves from the hook of the needle body to the tongue of the slider. Since the tip portion of the slider for holding the stitch is divided into two, the hook of the needle body driven by the subsequent carriage 200B can enter the gap and deliver the stitch.

  The selector driven by the rear carriage 200B is selected by the preceding needle selection actuator 13a as indicated by the tail end side butt locus 353B. As indicated by the select jack butt locus 352B, the butt of the select jack is pressed by the projecting movable presser 30, and the butt of the needle jack also sinks into the needle groove. As shown by the needle jack butt locus 351B, even if the rising cam surface of the raising cam 21 protrudes, the needle jack bat that sinks in the needle groove passes. The hook of the needle body advances to the tooth opening 2 by the action of the protruding eye receiving side stitch receiving cam 51 so that the stitch held by the slider extending from the front needle bed to the tooth opening 2 is received. The needle jack bat is driven. As shown by the slider bat locus 350B, the slider does not advance into the tooth opening 2.

  FIG. 5 shows a function of reducing the number of courses without providing an empty course when knitting the tubular knitted fabric 1 having a rib structure with the knitted fabric knitting cam device 201 of FIG. Indicates the switching state. In the course a1, in the right row 200R of the carriages 200F and 200B, the back stitch locked to the front needle bed is held in a state H held by a slider that advances from the front needle bed to the tooth opening 2 as shown in FIG. . In course a2, on the left side of the carriage, as shown in FIG. 3, the stitches are transferred from the back needle bed to the hook of the needle body that advances to the mouth 2 and, further, the front needle bed K is knitted and the back needle bed Then, knitting k of the back is performed. In the course a3, on the right side of the carriage, the back stitch knitted on the rear needle bed is transferred to the front needle bed. This transfer corresponds to the operation of moving the carriage to the right in FIG. 4 and transferring the stitches from the rear needle bed to the front needle bed. In the course a4, the rear line that is locked to the rear needle bed on the left side of the carriage is set to a state H that is held by the slider that advances from the rear needle bed to the tooth opening 2 as in FIG. In course a5, on the right side of the carriage, as in FIG. 3, the stitches are transferred from the front needle bed to the hook of the needle body that advances to the mouth 2 and, further, the back needle knitting k is formed on the front needle bed and the back needle bed is displayed on the rear needle bed. Perform eye organization K. In the course a6, on the left side of the carriage, as shown in FIG. 4, the back stitch knitted on the front needle bed is transferred to the front needle bed. In this way, the number of required courses can be reduced by eliminating empty courses.
