Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a stitch transfer carriage in a hand knitting machine.

Conventionally, this type of transfer carriage was mounted on a needle bed with a large number of knitting needles lined up so as to be movable in either the left or right direction, and the butts of the knitting needles sorted into two positions, front and back, were moved to either the left or right of the bed. Two bat passages in the front and back that are guided separately when moving in one direction, and two bat passages in the front and back that are guided separately when moving in the other direction are provided symmetrically with respect to the center of the carriage, and each of these two bat passages is provided. It is already well known that the stitches suspended on the front knitting needles among the knitting needles guided by the knitting needles are transferred to specific rear knitting needles located on the left and right opposite sides by the directionality of the left and right movement.

Further, in such a stitch transfer carriage, the carriage itself is equipped with a sorting member for sorting the butts of the knitting needles into two positions, front and back, and the butts of each knitting needle after the sorting are immediately placed in each of the two butt passages. It is also well known that a method is separately introduced to transfer stitches.

However, as shown in FIG. 4, for example, this type of conventional carriage has two butt paths A-H and B-H in the front and back when moving in one direction, and two butt paths A-H and B-H in the front and back when moving in the other direction. A pair of left and right sorting members S are provided on the outside of the passages A- and B- for sorting the butts of knitting needles into two positions, front and back. Since the sorting member S sorts out the knitting needles, and immediately following the sorting, stitch transfer is completed in the two batt passages on the same side, the sorting member S always selects the two batts. It has to be installed outside the area W of the passageway, which increases the length of the entire carriage in the left and right direction, resulting in a disadvantage that the carriage becomes larger.

In particular, a well-known knitting carriage is mounted on the needle bed, and the stitch transfer carriage used in conjunction with the knitting carriage is lightweight and compact in order to demonstrate its nimbleness. There was a big problem because it required that

However, in order to solve this problem, the present invention provides two front and rear positions that can be introduced into the respective entrances of two butt passages for stitch transfer on the left and right sides of the carriage for stitch transfer, respectively. The stitch transfer carriage is provided with first and second sorting members for sorting the butts of knitting needles, and when the stitch transfer carriage moves in either the left or right direction, the first and second sorting members located on the right side with respect to the center of the carriage move. While sorting the knitting needles with the sorting member, the stitches are transferred in the first two front and back butt passages located on the left side of the carriage,
When moving in the other direction, the second sorting member located on the left side with respect to the center of the carriage sorts the knitting needles, and the stitches are transferred using the second two front and rear butt passages located on the right side of the carriage. As a result, the first and second sorting members and two butt passages can be placed side by side in the same area in the left and right direction of the carriage, thereby reducing the size of the carriage. It was designed to make a significant contribution to the

A first embodiment embodying the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a stitch transfer carriage mounted on a needle bed (not shown) so as to be movable in either left or right direction. A first stitch transfer device transfers a stitch suspended from knitting needles 2 arranged in rows to an adjacent knitting needle 2 on the right side, and conversely transfers the stitch to an adjacent knitting needle 2 on the left side by moving to the left. The second stitch transfer device to be transferred is installed substantially symmetrically on the left and right sides with respect to the center of the carriage (X--X line in FIG. 1).

That is, first, the butt guide cam disposed on the back surface of the carriage 1 will be explained. Reference numeral 3 is a rear partition wall for forming a rear body needle passage, and one small advance cam 4 is formed in the center of the rear partition wall. , a pair of trapezoidal advancing cams 5 are formed at both side portions thereof.

Reference numeral 6 denotes a pair of rear cam bodies disposed in front of each of the trapezoidal advance cams 5, leaving a butt passage FG extending in the carriage movement direction, and a forward cam 7 is formed on each outer side thereof.

Reference numeral 8 denotes a pair of front cam bodies which are horizontally arranged in an elongated manner in front of the rear cam body 6, and a retracting cam 9 is formed on each outer side thereof.

Reference numeral 10 designates an island-shaped forward cam disposed between the two front force cam bodies 8, and 11 designates plate-shaped forward cams located on both rear sides of the island-like forward cam 10.

Reference numeral 12 denotes a front partition wall which is horizontally installed further forward of each of the front cam bodies 80, and forms a front body needle passage on the front side thereof, and a retreat lead-out cam 13 is formed on each outer side thereof.

Due to the arrangement of these cams, for example, when the carriage 1 is moved to the right, the knitting preparation position A (where the hook tip is located behind the sinker on the needle bed) is located on the rear side (left side of Figure 1) of the carriage 1. A first rear butt passage A-H that guides the butt of the knitting needle 2, and a first front butt passage B-H that guides the butt of the knitting needle 20 at the needle selection position B immediately before latch removal. , On the contrary, when moving to the left, similarly at the rear side and the side (right side of Figure 1),
A second rear butt passage A- that guides the knitting needles 20 at the knitting preparation position A and a second front bat passage B- that guides the knitting needles 20 at the needle selection position B immediately before latch removal. be done.

As is clear from FIG. 1, each of these bat passages is provided symmetrically on the left and right sides with respect to the line XX in the figure.

In conjunction with the above-mentioned butt guide cam, a cam member is provided at the front portion of the carriage 1 to raise or move laterally the front portion of the knitting needles 2 traveling through each of the butt passages.

That is, 14 is a front knitting needle (front butt passage B-H).

113-K is a needle raising cam that raises the front part of the knitting needle 2 above the upper end of the sinker, and 15 is a needle raising cam that slightly raises the front part of the rear knitting needle (knitting needle that travels through the rear butt passages A-H, l-K) 2. 16 is a needle moving cam that laterally moves the front part of the front knitting needle 2 raised by the needle raising cam 14; 17 is a needle that raises the front part of the front knitting needle 2 above the upper end of the sinker; This is a return cam.

Each of these cam members, like the butt guide cam, is symmetrical with respect to the line X--X in FIG. 1.

The stitch transfer carriage 1 equipped with the transfer device as described above has a part of the carriage 1 on each of its left and right sides.
The first and second knitting needles are used to sort the knitting needles 20 at the knitting preparation position A that have entered the carriage in the section into two positions, front and back.
A sorting member 18 is provided.

That is, 19 is a lowering cam provided in the batt passage FG, which causes all the knitting needles 20 butts guided to the butt passage FG to be subjected to an upward elastic force acting on each of the knitting needles 2. Press down against it.

Reference numeral 20 denotes a return cam that is provided subsequent to the lowering cam 19, and is designed to gradually allow the knitting needle 20 butts once lowered by the lowering cam 19 to return upward.

Reference numeral 21 denotes an inclined cam that is provided at the inner end of the bat passage FG so as to be inclined in the front-rear direction.

By the locking action of a selective locking member (not shown) in the needle bed, this inclined cam 21 straightly passes the knitting needle 2, which is in the position where it is pressed down by the pressing down cam 19, as it is.
After being pressed down, the knitting needles 2 which have returned upward along the return cam 20 are immediately advanced to a position where they reach the island-like advance cam 10 without being subjected to the locking action.

Reference numeral 22 denotes an actuating cam that utilizes the rear surface of the plate-shaped advance cam 11, which causes the knitting needles 2 that have linearly passed through the inclined cam 21 to retreat to the knitting preparation position A, and by the retreat, releases the release member in the needle bed. (not shown) to release the locking action and return the knitting needle 2 upward.

These specific configurations are based on, for example, the technology disclosed in Japanese Patent Publication No. 48-7900.

In FIG. 2, reference numeral 23 denotes a well-known knitting carriage for performing lace knitting involving transfer of stitches once to once in two stitches to once in third stitches when used in combination with the transfer carriage 1 and the like.

That is, on the back side of the knitting carriage 23, a large number of knitting cams 24 including the knitting main cam 24a arranged in a substantially square shape are arranged symmetrically, and the knitting cams 24 are arranged symmetrically on the back side of the knitting carriage 23. Even when moved, a plain knitting path A-D-C is formed that provides knitting operation to the knitting needles 2 at the knitting preparation position A.

The knitting carriage 23 of this embodiment is capable of knitting various patterns by itself, such as the well-known two-color simultaneous knitting. A pair of left and right needle selection members 25 are provided for sorting the butts of the knitting needles 2 that have passed through the rear end of the knitting needles 24a into a knitting preparation position A and a previous needle selection position B, and leading them out to the outside of the carriage.

That is, the needle selection member 25 is made to have substantially the same configuration as the stitch transfer carriage 10 selection member 18 described above.
A butt passage FG, a lowering cam 26, a return cam 27, an inclined cam 28, and an operating cam 29 are provided, and in addition to these, a laterally elongated partition wall 30 and one switching cam 31 are provided.

This switching cam 31 is supported so as to be switchable between a solid line position and a two-dot chain line position in FIG. The knitting needles 20 which are pushed open forward by the bat and advance from the inside are connected to the bat passage F-G.
lead to.

Therefore, in the knitting carriage 23, for example, by changing and arranging a part of the knitting cams 24 to the position shown by the two-dot chain line in FIG. Yarn knitting passage A-E-C,
Since the latch removal can form a colored thread knitting path B-D-C that guides the butt of the knitting needle 2 at the immediately previous needle selection position B, the carriage 23 is repeatedly moved left and right while keeping the cam arrangement. If so, simultaneous two-color knitting can be performed extremely easily and quickly.

This embodiment is configured as described above.

Therefore, when it is desired to use the carriages 1 and 23 having the above-mentioned configuration together to perform lace knitting involving, for example, a stitch transfer of two stitches, the knitting carriage 23 is moved from the plain knitting path A to the knitting path A.
The cam arrangement may be D-C, and the switching cams 31 on both sides may be arranged at the dot-dashed line position in Figure 2, that is, at the position where the needle selection member 25 is inactive.

After moving the knitting carriage 23 in either the left or right direction, the transfer carriage 1 is moved to adjoin the stitches suspended on the knitting needles 2 on either the left or right in accordance with the desired lace pattern arrangement. Depending on whether the stitch is transferred to the rear knitting needle 2, if it is to the right, it is moved to the right, if it is to the left, it is moved to the left, and the transfer of the stitch is automatically completed.

That is, when it moves in either the left or right direction, each knitting needle 20 butt in the knitting preparation position A that enters the carriage with the movement moves into the first or second knitting needle 20 located on the front side in the carriage movement direction. Under the action of the sorting member 180,
Near the center of the carriage, it is sorted into two positions A and H, front and rear.

Thereafter, the knitting needles 20 that have been sorted into the two positions A and B are placed in the first two front and rear butt paths A-H and B-■ or the second front and rear butt paths A-H and B-■ located on the rear side in the carriage movement direction. Two bat passages A-K.

B-K are guided separately, whereby the stitches suspended on the front knitting needles 2 are transferred to the rear knitting needles 2 adjacent to the front side in the carriage movement direction.

The stitch transfer action is carried out by a well-known method, but to briefly explain its outline, the front part of the front knitting needle 2 is raised by the needle raising cam 14, and the front part is moved backward by the needle moving cam 16. The front knitting needle 2 is laterally moved until it intersects with the knitting needle 2, and when the knitting needle 2 crosses the knitting needle 2, the front part of the front knitting needle 2 comes off the needle raising cam 14 and descends, and overlaps the upper surface of the rear knitting needle 2 in a crossing state.

Thereafter, the rear knitting needle 2 is advanced by the advancing cam 7 of the rear cam body 6, and its distal end hook portion enters the stitch suspended from the front knitting needle 2.

Subsequently, the front part of the front knitting needle 2 is lifted by the needle return cam 17, and the front part returns between the original sinkers.

As a result, the stitches are also passed over the rear knitting needles 2 which have not yet advanced beyond the latch removal position.

As a result, when the rear knitting needles 2 are retreated all at once to the knitting preparation position A by the retraction cam 9, the stitches are pulled rearward by the hooks of the rear knitting needles 2, and are reliably pulled out onto the front knitting needles 2.

Following this, the front knitting needles 2 are retracted all at once by the retracting lead-out cam 13 to the knitting preparation position A, whereby the stitches are knocked over from the front knitting needles 2 and the rear knitting needles 2
will be moved to

After the stitch transfer is completed as described above, it is only necessary to move the knitting carriage 23 again. From then on, by repeating the above operation, a desired type of lace pattern with three stitches and one stitch transfer is created. can get.

Sometimes, when it is desired to perform lace knitting with one stitch transfer for three stitches, after moving the knitting carriage 23,
moving the relocation carriage 1 in either the left or right direction;
Furthermore, the transfer carriage 1 only needs to be turned back and moved in the other direction, thereby obtaining the desired type of lace pattern.

Of course, it is necessary for each sorting member on the transfer carriage 1 to sort the knitting needles 20 butts into a pattern that allows three stitches to be transferred once, and for this purpose, the selection locking member is Be careful with controls.

Next, a second embodiment embodying the present invention will be described with reference to FIG.

This embodiment differs from the previous embodiment only in the structure of the stitch transfer carriage 1, and only that carriage will be described.

In Fig. 3, numeral 32 is a stitch transfer carriage mounted on the needle bed so as to be movable in either left or right direction. Bat guide cams are provided on the left and right sides for substantially symmetrical stitch transfer.

That is, 33 is a rear partition wall for forming the upper part of the rear knitting needle 2, and a pair of small advancing cams 34 are formed on each outer portion thereof, and a pair of trapezoidal advancing cams 35 are formed on each inner portion thereof.

Reference numeral 36 designates a pair of rear cam bodies disposed in front of each of the trapezoidal advance cams 35, leaving a butt passage FG extending in the carriage movement direction, and a forward cam 37 is formed at each inner portion thereof.

Reference numeral 38 denotes a pair of front cam bodies installed horizontally in an elongated manner in front of the rear cam body 36, and inner and outer retracting cams 3 are provided at each inner part of the front cam bodies.
9 and 40 are formed.

Reference numeral 41 denotes a front bulkhead horizontally installed further forward of each of the front cam bodies 38, on the front side of which a front knitting needle 2 is formed.
One chevron-shaped retraction cam 42 is formed at the left and right intermediate portions.

Reference numeral 43 designates a pair of plate-shaped forward cams arranged further outside of each of the rear cam bodies 36.

Due to the arrangement of these cams, for example, when the carriage 32 is moved to the right, the knitting needles 20 at the timing position E, which is slightly ahead of the knitting preparation position A, on the front side in the direction of movement - 1 section (3rd national ownership) A second rear butt passage E-M for guiding the knitting needle 20 butt at the needle selection position B immediately before latch removal, and a second front butt passage B-M for guiding the knitting needle 20 butt at the needle selection position B immediately before the latch is removed. When moving to the left,
Similarly, on the front side in the moving direction (left side in FIG. 3), there is a first rear butt passage E-N that guides the knitting needle 20 butt at the timing position E, and a first rear butt passage E-N that guides the knitting needle 20 butt at the needle selection position B. A first front butt passage B-N is configured.

As is clear from FIG. 3, these bat passages are provided symmetrically on the right and left sides with respect to the line XX in the same figure.

Further, the configuration of the cam member that moves upward or laterally in the front portion of the knitting needle 2 traveling through the butt passage is the same as in the previous embodiment.

On both left and right sides of the stitch transfer carriage 32 configured as described above,
At one side of each of the carriages 32, there are first and second butts for sorting the butts of the knitting needles 2 that have retreated along either of the retreating cams 39 and 40 into two positions, front and back, and guiding them out of the carriage. A sorting member 44 is provided.

That is, the sorting member 44 is arranged in the bat passage F- so that its configuration is substantially the same as that of the sorting member 18 in the previous embodiment.
G, a lowering cam 45, a return cam 46, an inclined cam 47, and an operating cam 48 are provided, and an island-shaped knitting needle 20 butt advanced by the inclined cam 47 is further advanced to the needle selection position B immediately before latch removal. A forward lead-out cam 49 is provided.

In the figure, reference numeral 50 denotes an introduction cam that slightly advances the knitting needles 20 butts at the knitting preparation position A to the timing position E.

This embodiment is configured as described above.

Therefore, by using the transferring carriage 32 having the above-mentioned configuration in combination with the knitting carriage 23 having a cam arrangement similar to that of the previous embodiment, lace knitting with stitch transfer of two stitches at a time can be easily performed.

That is, after moving the knitting carriage 23 in either the left or right direction, the transfer carriage 32 is first moved to move the stitches suspended from the knitting needles 2 to the left or right according to the desired lace pattern arrangement. Depending on whether it is to be moved to the adjacent rear knitting needle 2, if it is on the right, it may be moved to the left, and if it is on the left, it may be moved to the right.

As a result, when moving in either the left or right direction, the knitting needles 20 butts that were already aligned at the knitting preparation position A are moved to the second rear butt passage E-M located on the front side in the carriage movement direction. First rear bat passage E-
N, the needles are sorted into the timing position E and the needle selection position B by the action of the first or second sorting member located on the rear side in the direction of carriage movement, and are led out to the outside of the carriage.

After that, if the transfer carriage 32 is turned back and moved in the opposite direction, the knitting needles 20 in the two positions E and B selected during the previous transfer will be moved as follows.
The stitches suspended on the front knitting needles 2 are guided separately to the two butt passages on the same side as the first or second sorting member 44 that has made the sorting, so that the stitches suspended on the front knitting needles 2 are similar to those in the previous embodiment. In this manner, the knitting needles 2 are transferred to the rear knitting needles 2 adjacent to the front side in the direction of carriage movement.

At this time, each knitting needle 20 butts that have completed the transfer act again on the first or second sorting member 44 on the rear side in the direction of carriage movement. Since it is not necessary to sort out the 20 butts, all of the 20 knitting needles are separated by the inclined cam 47.
After passing in a straight line as it is, it is aligned with the timing position E and guided out of the carriage.

It is clear from the description of the previous embodiment that this selection operation is performed by the selection locking member within the needle bed.

After the stitch transfer is completed as described above, it is only necessary to move the knitting carriage 23 again.
A knitting operation is applied to each knitting needle 2 that was previously aligned at the time position E.

However, it is clear that at this time, each of the knitting needles 20 at the timing position E can be introduced into the plain knitting path A-D-C.

Sometimes, when it is desired to perform lace knitting with stitch transfer exactly on the front stitch, the transfer carriage 32 is moved in one direction to the left or right, and the first or second sorting is carried out on the rear side in the direction of movement. After the knitting needles 20 are sorted by the member 44, it is necessary to move the transfer carriage 32 back, first to transfer stitches in one direction, and to select the knitting needles at the same time as the transfer.

From now on, the transfer carriage 32 is turned back again to perform stitch transfer in the other direction, thereby completing the stitch transfer for three stitches at a time.

At this time, the fact that each knitting needle 20 butts are aligned and guided to the waiting position E is the same as in the case of the three stitches and one stitch described above.

After completing the three stitches and one stitch transfer in this way,
It is only necessary to move the knitting carriage 23 again, and by repeating these operations as appropriate, a desired type of lace pattern with one stitch transfer can be obtained.

Incidentally, as in the second embodiment, the transfer carriage 3
2 is provided with a first or second sorting member 44 that acts on the rear side in the carriage movement direction, the carriage 3
By moving the knitting needles 2 in either the left or right direction, the knitting needles 20 aligned at the knitting preparation position A can be sorted into two positions, front and back, and led out to the outside of the carriage without any of them being pulled out. Since the function as a selector can be performed without requiring a special cam operation, this is sometimes convenient when knitting various patterns such as two-color simultaneous knitting using the knitting carriage 23 alone.

For example, if you accidentally move the knitting needle 20 in the front and back direction during knitting, such as two-color simultaneous knitting, you do not know which of the two positions A and H should be sorted. , or when knitting is to be resumed after several courses of knitting due to a knitting failure, the 20 knitting needles that have been aligned in advance at rear position A are accurately selected before the next knitting. However, in such a case, it can be handled easily and quickly by moving the transfer carriage 1 as it is.

As explained above, the present invention has the first two front and rear butt passages and the second two front and rear batt passages located at the center of the carriage so that the stitches can be moved in either the left or right direction. On the other hand, in a stitch transfer carriage provided symmetrically on the left and right sides, each entrance of two butt passages for stitch transfer is provided on both the left and right sides of the stitch transfer carriage, respectively, on the left and right sides of the carriage. In preparing the first and second sorting members for sorting knitting needle butts in two positions, front and back, which can be introduced into While the knitting needles are sorted by the first sorting member located on the right side, stitches are transferred in the first two front and back butt passages located on the left side of the carriage, and when moving in the other direction, the needles are transferred to the center of the carriage. The second one located on the left side
The knitting needles are sorted by the sorting member, and the stitches are transferred in the second two front and rear butt passages located on the right side of the carriage.

Therefore, as is clear from comparing the drawings showing each of the above-mentioned embodiments and the drawings showing the conventional example, the first and second sorting members and the two butt passages are arranged at the same position in the left and right direction of the carriage. It can be installed within the area, thereby
It has excellent effects such as being able to accurately perform the specified needle selection and stitch transfer operations without causing any trouble, thereby greatly contributing to the miniaturization of the carriage and greatly improving its operability. .
