Description

DETAILED DESCRIPTION OF THE INVENTION [Subject of the Invention] The present invention relates to a carriage for a hand knitting machine, and more particularly to one equipped with both stitch transfer and knitting devices.

[Conventional device]

As a conventional technique for simplifying the knitting operation in which a stitch suspended on a knitting needle is transferred to an adjacent knitting needle, and then knitted with both knitting needles to create a stitch, Japanese Patent Application Laid-Open No. 49
-No. 31950, Special Publication No. 16356, Publication No. 16356, Publication No. 16356-
Publication No. 134239 can be seen.

[Problems with conventional technology and technical analysis thereof]

However, in JP-A No. 49-31950,
Although this method allows stitches to be transferred and knitted by one slide of the carriage, other tack stitches,
In order to perform pattern knitting such as smooth stitch knitting and two-color simultaneous knitting, it is necessary to use a completely different pattern knitting carriage, which places a heavy burden on the operator. In addition, in the model of Japanese Patent Publication No. 42-16356, a stitch transfer device is simply connected to the left and right ends of the conventional carriage, and after stitch transfer, the knitting cam A on the side of the stitch transfer device advances the knitting needles to the flattening position. On the other hand, knitting was performed using the knitting cam B. Therefore, it is necessary to complete the entire stitch transfer process before the knitting needles reach the knitting cam A, which inevitably increases the size of the carriage.

Furthermore, in the case of JP-A No. 56-134239, the stitch transfer is completed by retracting the knitting needles not on the stitch transfer device side but on the other side, that is, the knitting cam B, and the stitch transfer is completed by the knitting cam B. Stitch transfer was performed in one sliding motion, and knitting was performed in the next sliding motion. In this way, since the stitches are transferred and knitted by sliding the carriage twice, the operation becomes complicated and is not sufficient to achieve the purpose of simplifying the operation.

Investigating the technical deficiencies of these conventional devices, it is found that there is no cam that allows the knitting needles that have passed through the knitting cam A on the side where the stitch transfer device is located to be removed just before the knitting cam B on the other side. caused by. And in order to do more pattern knitting,
Various cams, such as the central front guide cam 10, central rear guide cam 11, and tack cam 13 described in JP-A-56-134239, are installed between the nipping cams A and B.
It was found that various cams such as the following were required.

[Technical issues]

In this application, a cam for removing the flattening is provided between the knitting cams without impairing the function of pattern knitting, and a single sliding movement of the carriage transfers and knits the stitches, and also performs pattern knitting. The object of the present invention is to create a hand knitting machine carriage that is small and easier to operate.

[Technical means]

The present invention attempts to solve the above problems by the following means.

In other words, the middle (inward) of the left and right knitting cams
A horizontally long movable central guide cam that can be moved to two positions, a forward position and a rearward position, is provided. And when this movable central guide cam moves to the forward position,
Needle advance cams are provided at both left and right ends of the guide cam so as to close the gap with the rear partition wall of the carriage, and a fixed central cam is provided to advance the knitting needles to a position where they can be reliably removed.

[Effect of technical means]

When performing stitch transfer, the movable central guide cam is placed in the forward position, and one stitch transfer device completes the stitch transfer. Then, the knitting needles that have passed behind the knitting cam on the same side are advanced by a needle advancement cam that closes between the movable central guide cam and the rear bulkhead, and then pass through the movable central guide cam and then to the fixed central cam. He guides her to the place and removes her hair.

After this flatness is removed, knitting is performed using the other knitting cam, and the stitches are transferred and knitted all at once with one sliding movement of the carriage.

Furthermore, when pattern knitting, for example, tuck knitting, the movable center guide cam is removed to the rear position, and the needle advancing cam is arranged so as to close the space between the guide cam and the rear partition wall.

Then, by opening the raising cam and opening the stitch transfer device, a tack knitting path is obtained through which the knitting needles are advanced and passed until just before they are removed.

In this way, even when the movable central guide cam is in the forward or rearward position, and even when the movable central guide cam occupies the forward position, the needle advancement cam and the fixed central cam cooperate to close the gap with the rear bulkhead. By this action, the knitting needles are advanced to the flattening position inside the knitting cam, and a pattern knitting path for tuck knitting and the like can also be formed.

[Special effects produced by the present application]

The apparatus of the present invention configured as described above can transfer and knit stitches with one sliding movement of the carriage without impairing the pattern knitting function, and contributes to downsizing of the carriage. In addition, by arranging the movable center guide in the front or rear position, the needle advance cam closes the gap between the movable center guide cam and the rear bulkhead and moves the knitting needles forward in either position, making it easy to operate. can be greatly simplified and the structure can be made simple.

〔Example〕

A large number of knitting needles 2 and comb teeth are arranged in a row on a needle bed (not shown). Each of the knitting needles 2 is particularly capable of sliding back and forth, and its front portion can be curved in the lateral direction past the comb teeth up and down to the position of the adjacent knitting needle.

A carriage 4 is provided with front and rear sliding hooks 5 and 6 to slide on the needle bed, and the following cams are arranged symmetrically on the lower surface thereof. That is, 7 and 8 are
The front and rear partition walls form the front and rear body needle passages, respectively, and the left and right intermediate parts between the two partition walls include various cams for making various knittings such as two-color simultaneous knitting, as well as the left and right cams. Cams for stitch transfer are arranged on both sides.

First, to explain the various cams, 9 in the figure.
Reference numeral 10 indicates a nitting cam that performs a knitting action on the inner surface and a lasing action on the outer surface, 10 indicates an intermediate partition wall horizontally fixed between the above-mentioned knitting cam 9 and the front partition wall 7, and 11 indicates the left and right knitting cams 9.
A fixed central cam 12 is fixedly disposed at the center of the cam, and a movable central guide cam 12 is mounted at the rear of the cam so as to be movable back and forth. When this movable central guide cam 12 moves to the side, its front edge is connected to the fixed central cam 11.
When moving backward, there is a gap between the front wall of the rear bulkhead 8 and the rear edge of the movable central guide cam that allows the width of the butt of the knitting needle 2 to pass through. Further, the front edge at this time is provided with a butt passage at a position where the knitting needles 2 do not fall off. Reference numeral 13 denotes a movable retracting cam which is arranged between the uniting cam 9 and the movable central guide cam 12 so as to be able to rotate and switch between three positions, and 14 is arranged between two positions on both left and right sides of the movable central guide cam 12. A switchable needle advancing cam 15 is a lasing cam that can be switched between two positions at the rear end of the knitting cam 9.
Reference numeral 16 denotes an auxiliary switching cam provided on the outer side of the intermediate wall 10 so that the arrangement can be switched between two positions, 17 a one-way spring that moves vertically and provided in the front knitting passage of the left and right intermediate wall 10, and 18 the left and right Intermediate wall 1
This is a forward swing cam that is rotatably provided inside the 0.

On the other hand, to explain the stitch transfer cams, 2
0 is a front guide cam that guides the lace knitting stitch transfer needle fixedly arranged on the carriage 4, and an introduction switching cam 21 is provided at the outer end of the front guide cam. Reference numeral 26 denotes a path switching cam provided inside the front guide cam 20, which is provided at the connecting portion between the knitting front path and the stitch transfer path, and which transfers the same stitch without changing the butt of the knitting needle in the stitch transfer path. It is arranged so as to be switchable between a state in which it is advanced to a private passageway and a state in which it is introduced into a rear formation passageway. Reference numeral 27 denotes a fixedly formed inner front guide cam, which has a generally four-sided shape, and has a bearing portion rotatably receiving the path switching cam 26 at its outer corner, and its front portion is connected to the front guide cam 27. A knitting needle butt passage is formed between the partition wall 7 and the rear side surface thereof. Further, a retreating passage connected to the forward switching position of the raising cam 15 is formed on the outer inclined surface, and a passage through which the knitting needle butt is advanced forward by the knitting cam 9 is secured on the inner inclined surface. In addition, a passageway is also formed in the front inward direction, through which the auxiliary switching cam 16 can be retreated when switched forward. Reference numeral 28 denotes a switching cam that can be switched between two positions: a position for retracting the knitting needle that has inherited the stitch, and a path connected to the front guide cam 27, and 29 for retracting the knitting needle that has inherited the stitch introduced by the switching cam 28. This is a fixed rear guide cam. Next, referring to the needle selection device installed in this carriage, 30 switches the butt of the knitting needle introduced by the knitting cam 9 and the raising cam 15 into the needle selection preparation position and the two positions where it is not introduced. This is a possible needle selection selection cam, and its rotary shaft support part connects the butt with an introduction inclined surface 31 for lowering the butt part of the knitting needle to a locking member (not shown) of the S plate (needle selection member). This is a convex ridge 32 necessary for the existing needle selection device, which provides the necessary margin for locking the rear shank portion of the knitting needle butt with the S plate while the knitting needle butt remains pressed down. Reference numeral 33 is a needle selecting/selecting cam that tilts the needle butts that have entered this passage horizontally outward from the convex ridge 32 from the front to the rear, and the central part is for removing the low butts that are lowered and locked by the convex cam 32 as they are. It has a guide section that has a height that prevents the high butt from passing through in the opposite direction, and guides the high butt backward by its inclination. In addition, the front part moves the butt of the stitch succession knitting needle that enters from the outside of the carriage to the switching cam 2.
It consists of a shape that can be introduced up to 8 positions. Reference numeral 34 denotes a path switching cam that can switch the butt of a knitting needle that inherits a stitch between two positions: a path necessary for stitch transfer and a path unrelated to the transfer. Formed at 35 is the convex cam 3
Located in front of 2 and at its front edge is a fixed partition cam that introduces the needle butt into the switching cam 28 position.
36 is a low butt release cam adjacent to the outside of the needle selection and selection cam 33. The low butt is again pressed down on the side adjacent to the needle selection and selection cam 33, the needle and shank are lowered again, and the S plate (needle selection) is removed. There is a front slope that helps the S plate move backward to release the lock (not shown) and a rear slope that allows the knitting needle butt to return to its conventional high position after the S plate is released, and the front edge sides of both slopes are forming a passageway introduced by the diverting cam;

Next, on the front side of the carriage 4, there is installed a pair of auxiliary devices that can be replaced and removed depending on the case of lace knitting or pattern knitting other than lace knitting, such as two-color simultaneous knitting. So I will explain this. First, to explain the stitch transfer auxiliary body A used for lace knitting, 40 in the figure is a board made of a sheet metal member bent into a substantially U-shaped cross section with an opening at the rear, and the rear end of the upper flat part. A pair of left and right fitting grooves 43 are provided to fit into male threads 42 of tightening screws 41 provided on the left and right sides of the front portion of the carriage 4. The base plate 40 can be attached to and detached from the carriage 4 using a tightening screw 41, and an opening groove 4 that opens upward, downward, and forward is formed in the front side between the left and right sides of the base plate 40.
4 is provided. 45, the base end is connected to the substrate 40
The yarn opening plate is fixed to the inner side of the left and right center of the knitting yarn T.
A supply hole 46 is provided for supplying. Stitch passing devices are provided on the left and right substrates of the yarn opening plate 45, respectively. The stitch transfer device A includes a needle raising cam 47 that raises the front part of the knitting needle 2 in the stitch transfer path Y1 above the upper end of the comb teeth 3, and a needle raising cam 47 that raises the front part of the knitting needle 2 in the stitch transfer path Y1 above the upper end of the comb teeth 3, and A slip-off preventing member 48 is provided which engages with the lower surface of the opened latch to prevent the stitches suspended above the latch from slipping off. Then, connect the front part of the knitting needle 2 of the stitch succession passage X1 to the comb teeth 3.
Open needle raising cam 4 that raises it slightly above the upper end
9 and the needle raising cam 47 and the lug removal prevention member 4
A needle bending member 50 is provided which bends the front portion of the knitting needle 2, which is subjected to the action of 8, until it intersects above the hook of the knitting needle 2 in the stitch succession passageway X1 adjacent in the sliding direction of the carriage. In addition to this configuration, the front portion of the knitting needle 2 curved by the member 50 comes off the inner step portion 51 of the needle raising cam 47 and descends, so that it is attached to the hook of the knitting needle 2 in the stitch succession passage X1. The knitting needles 2 cross-joined and in the stitch succession passage X1 are connected to the needle selecting and selecting cam 33.
is advanced by the front inclined surface of the This results in
After the hook enters the stitch of the knitting needle 2 in the stitch transfer path Y1 from behind, the front part of the knitting needle 2 in the stitch transfer path Y1 is again raised above the upper end of the comb teeth 3, and the stitch succession path X1 A return cam 52 is provided to release the knitting needle 2 from the hook and return it to its original position. The above-described operation of the stitch passing device A is carried out according to a known method, and the knitting needles 2 of the stitch transfer path Y1 are
and the knitting needle 2 of the stitch succession passage X1 adjacent to this
and retreat through a path formed by the corresponding course switching cam 26, inner guide cam 27, and raging cam 15.

On the other hand, the stitch succession passage is retracted by a passage consisting of a switching cam 28 and a rear guide cam 29. In this case, the knitting needles in the stitch transfer passage are the raising cam 1.
By reaching the rear end of No. 5, the stitch becomes a knock-over position (a position where the stitch is removed from the hook forward) and the stitch is removed. On the other hand, the knitting needles 2 that have passed through the stitch succession path hold in their hooks two stitches: the stitches held before entering the carriage and the stitches transferred by the stitch transfer device A, and the stitch transfer operation is completed. In the figure, reference numeral 53 designates magnets fixed to the inner surfaces of the left and right sides of the substrate 40, which cause the latches of the knitting needles 2 in the stitch succession passage X1 to open in an upright position immediately before the flatness prevention plate 48. Reference numeral 54 denotes an inner magnet fixed to the inner upper part of the base plate 40 between the yarn opening plate 45 and the stitch passing device A, and is used to connect the yarn opening 4 of the yarn opening plate 45
At step 6, the latch of the knitting needle that receives the yarn is opened and raised.

On the other hand, to explain the knitting auxiliary body U used for pattern knitting such as two-color simultaneous knitting, reference numeral 60 in the figure is a support plate bent into an approximately L-shape in cross section, and the rear edge of the upper plane part. A pair of left and right fitting grooves 43 that fit into the male threaded portions 42 of the tightening screws 41 are provided on the left and right sides of the holder, and can be attached and removed by tightening the tightening screws 41. 61 is a plate-shaped knitted fabric presser fixed to the left and right sides of the front lower surface of the support plate 60, which is close to the front edge of the comb teeth 3 to prevent the knitted fabric from advancing. Brush wheels and other equipment are supported to prevent ground invasion. 62, the substrate portion is the support plate 60
The clue board is fixed to the upper and lower surfaces of the left and right center parts of the
At the left and right center of the lower plane part, there is a front yarn opening 63 that supplies coloring knitting yarn to the hooks of the knitting needles 2 in the front knitting passage, and a rear yarn opening 64 that supplies ground knitting yarn to the hooks of the knitting needles 2 in the rear knitting passage. and is provided. 65
The latches of the knitting needles 2 in the front knitting passage and the back knitting passage are opened by brushes fixed to the upper part of the support plate 60 on the left and right outer sides of the yarn opening plate 62.
A protective cam 101 protects the tip of the needle advance cam 14, and is made of a thin plate spring-like member, and advances knitting needles that enter from one side, and sinks downward against knitting needles that enter from the other side. This is a configuration that allows it to pass through. The part of the tip of the needle advancing cam 14 that comes into contact with the rear partition wall, and the surface perpendicular to the needle entry direction, protrudes into the knitting needle passage, and has the effect of preventing the passage from being obstructed and protecting the cam tip and the knitting needles. have

Next, methods of implementing patterns such as lace knitting, two-color simultaneous knitting, stockinette knitting, slippery knitting, and tack knitting will be explained. First, starting with the lace version shown in FIG. Place it in each position shown in the figure. Further, the knitting needles 2 in the knitting section involved in knitting the knitted fabric are sorted into a knitting preparation position X1 and a needle selection position Y1 by a needle selection means to be described later. (In this case, selection is made so that two or more knitting needles 2 at the needle selection position Y1 are not selected consecutively.) After this, by sliding the carriage 4 from the outside of the knitting section into the same section, As shown, the knitting needles at the needle selection position are introduced into the stitch transfer path connected by the two-dot chain line indicated by Y1, and the knitting needles 2 at the knitting preparation position X1 are introduced into the stitch succession path connected by the two-dot chain line indicated by X2. be introduced. By the time the butts of these knitting needles 2 are guided to the inner side of each passage, the stitches suspended from the knitting needles 2 of the stitch transfer passage Y1 are transferred to the stitches adjacent to the front side in the carriage sliding direction according to a known method. It is hung over the hook of the knitting needle 2 in the passageway X1. After this, the stitch transfer passage Y1 is 26
The needles 2 are moved backward by the inner guide cam 27 of the course switching cam 27 and the parallel raising cam 15, and the knitting needles 2 reach the knock-over position (a position where the stitches come forward from the hooks), remove the stitches, and complete stitch transfer. On the other hand, the knitting needle 2 that has entered the stitch succession path When they merge, the stitch transfer of the knitting needles 2 in both paths is completely completed.

Thereafter, the two needle paths merge, and after being moved forward a little by the protection cam 101, the needles are moved forward by the tack cams 14 on both the left and right sides of the movable central guide cam 12, which overlaps the fixed central cam 11, and the knitting needles that have come loose on the way are moved forward. The second latch is opened by the magnet 54, and the hook reaches the lower surface of the thread opening plate 45.
(FIG. 3) Here, after the knitting yarn T is supplied to the hook portion of the knitting needle 2 through the yarn port 46, the butt portion is moved back by the inclined surface located at a high position of the one-way cam 17. Next, the needle butts pass through the inner inclined surface of the intermediate wall 10, the movable retraction cam 13, and the knitting cam 9, and the knitting needles 2, which have passed through the stitch succession path X1, reach the knockover position again and start the stitch. form. On the other hand, the knitting needles that have passed through the stitch transfer path Y1 are in a state where the knitting needles T are still being supplied into the hooks and have not yet completely formed a stitch.
Thereafter, each butt part of the knitting needles 2 in both passages is introduced into the lowering cam 32 by the needle selection and selection cam 30, where all the needle butts are at a low position where the amount of protrusion from the groove plate is small, and the needle butts of the knitting needles 2 The needles are sorted into knitting needles that are engaged with the S plate (needle selection plate - not shown) in the shank and those that are not, and after passing through the lowering cam 32,
The butt height of the engaged knitting needle 2 is maintained at a low position. On the other hand, the butt of the knitting needle 2 that is not engaged returns to its original high position. Thereafter, when passing through the needle selecting and sorting cam 33, depending on the height of the wall that stands up, low butts pass through as is, while high butts cannot pass through, and the butt part retreats due to the inclined side wall. As a result, the knitting needles 2 are selected by the needle selection device using a known selective selection method and reach the outside of the carriage 4, but these S plates (needle selection plates) are not connected to the position where the shank portion of the knitting needle 2 has descended. Whether or not to move for stopping is determined by a conventionally known method (not shown) depending on whether or not there is a hole for the inserted punch card in the drive device for the S plate installed behind the groove plate. However, here, the knitting needle 2 that has passed through the previous stitch transfer passage does not form a complete stitch loop with only the knitting yarn T hanging around its hook, so the subsequent carriage 4 returns Sliding requires an additional stage of organization. Therefore, it is assumed that all the holes of the punch card are set to the inside state (the state in which the S plate does not move for locking). However, all the butts that have passed through the convex ridge 32 for rolling down the butts of the knitting needles 2 are placed at a high position with respect to the groove plate 1, so that they do not pass laterally through the upright wall of the needle selection and sorting cam 33, but instead move backwards. The tip of the path switching cam 34 is connected to the rear bulkhead 8 at the rear.
It is opened by the width of the butt of the knitting needle 2, and the outer side X2 of the carriage 4 shown in FIG.
The knitting needles are aligned and one sliding movement of the carriage is completed.

Next, when the carriage 4 slides in the opposite direction to the sliding direction described above, the tip of the path switching cam 34 is moved back again by the spring after the butt part passes through the opening in the carriage sliding direction. The butt of knitting needle 2 which has returned to the partition wall 8 side and is aligned at X2 is moved forward and passes through the stitch inheritance passage on the left and right side opposite to that in Fig. 1 (in this case, there is no knitting needle at the needle selection position, so stitch transfer is not possible) (Not performed) Opened Raging Cam 15
to the rear of the After that, the knitting needle 2 is moved by the tact cam 14.
moves forward, and when the butt of the knitting needle 2 reaches the fixed central cam 11, the thread end 4 of the thread end plate 45 is attached to the hook portion.
Knitting cam 9 receives the supply of twisted knitting yarn T from 6.
to the rear of the The next button is the needle selection cam 30.
When it is rolled down at the convex ridge 32 via the introduction slope 31, the S plate (needle selection plate) is selectively engaged, and after passing through the convex ridge 32, a butt having different heights is generated. Then, the high butt is moved backward by the needle selection and selection cam, and the low butt passes laterally and reaches the low butt release cam 36, where it is pressed down again to release the S plate and return to the high butt. . Then, the switching cam 21 is pushed forward against the spring and aligned at the needle selection position, while the needle selection and selection cam 33
The knitting needles 2 that have retreated at , rotate and push forward against the course switching cam 34 against the spring to be aligned at the knitting preparation position, and the sliding movement of the carriage 4 is completed. As described above, in correspondence with a needle selection instruction member such as a punch card, by sliding this carriage 4, lace knitting can be easily performed by the action of the various cam groups arranged on the carriage and the stitch transfer auxiliary body A. be able to. In the case of three stitches or cross stitches related to lace knitting, flat knitting may be performed after repeating the needle selection action and the stitch transfer action by reciprocating sliding of the carriage 4 a predetermined number of times. Also, it goes without saying that stockinette knitting may consist of only one course or three or more consecutive courses depending on the knitted fabric to be knitted.

Next, the tack section will be explained with reference to FIG. In this case, the knitting yarn T is inserted only through the rear yarn opening 64, and the cams on the lower surface of the carriage 4 are arranged as shown in FIG. The butt of the knitting needle 2 within the knitting section pressure is moved to the knitting preparation position R1 according to the pattern of the pattern.
and needle selection position S1. By sliding the carriage 4 into the knitting section, the needle selection position S
The knitting needle 2 of No. 1 passes through the stitch succession path, passes through the path switching cam 26, passes through the auxiliary switching cam 16, and reaches the path formed by the rear of the fixed central cam 11 and the front edge of the movable central guide cam 12, and the knitting needle 2 The knitting yarn T is supplied to the hook to knit the stitches. One formation preparation position R1
The knitting needles continue straight and reach the protection cam 101 and the needle advancement cam 14, and the butt moves forward and the knitting yarn T is fed into the hook at the front edge of the movable central guide cam 12. (Stitches are not knitted) After this, the butts of all knitting needles 2 are set by the needle selection cam 30.
is introduced into the needle selection device and led out to R2 and S2. For knitting from the next course onwards, the needle selection action and carriage sliding may be repeated.

Next, the smooth stitch can be achieved by the cam arrangement shown in FIG. At this time, the knitting needle SL passing through the protective cam 101 part from the inside of the carriage is
01 and proceed. Furthermore, simultaneous two-color knitting can be achieved by the cam arrangement shown in FIG.
