Description

DETAILED DESCRIPTION OF THE INVENTION The first aspect of the present invention is that the knitting needles run independently on the needle bed, in addition to the knitting needles that apply knitting motion to the knitting needles arranged in rows on the needle bed to form stitches. A carriage dedicated to stitch transfer is provided, and during lace knitting, the carriage for stitch transfer and the carriage for knitting are run alternately on the needle bed, and the carriage for stitch transfer first moves signal carriers such as signal cards for knitting. The knitting needle butt for stitch transfer is sorted into two positions, one for stitch transfer and the other for stitch transfer, out of the two positions before and after, by a first sorting member that is fed independently of the carriage and is provided in the carriage. Then, the stitch transfer mechanism transfers stitches to create stitches for lace knitting, and by running the knitting carriage on the needle bed, the signal carrier is sent or sent in the same way as the stitch transfer carriage. The stitch transfer and knitting movements are divided between a stitch transfer carriage and a knitting carriage, and the stitch transfer and knitting movements are shared by a stitch transfer carriage and a knitting carriage. When transferring stitches using a stitch transfer carriage, it is essential to send a signal carrying member.
The main purpose of the knitting carriage is to not feed the supporting member when flat knitting is performed using the knitting carriage, but to feed it only when pattern knitting is performed.

Further, the second invention has the first invention as the main part of the invention, and the signal supporting member includes a knitting needle arrangement signal stage that does not require stitch transfer in connection with the running of the stitch transfer carriage.
A signal for aligning all of the knitting needle butts to the other position is provided to provide a knitting needle arrangement that does not substantially cause stitch transfer, thereby further increasing the usefulness of the first invention. The purpose is to

Knitting carriages and stitch transfer carriages are each well known, but these are used interchangeably.In particular, a signal carrier is sent to the stitch transfer carriage as it runs, and the transmitted signal is transmitted to the stitch transfer carriage as it runs. There is no carriage that transfers stitches according to this method, and the transfer carriage is run after selecting knitting needles with a fingertip, and the automation efficiency is extremely low.

In addition, the belt 10 has a number of engagement holes 37 that are slightly elongated and arranged in a row with a certain pinch over the entire length of the belt 10 to mesh with the teeth of the rotary wheel 9. (in this embodiment, the distance corresponding to 24 knitting needles) is formed to be thick in the lateral direction to form the connecting hole 38.

On the lower surface of the knitting carriage 39, as shown in detail in FIG. 9, a knitting cam group 40 forming the pattern knitting cam mechanism of the present invention is installed in the center, and the main force passes through the cam groups 40 on both outer sides of the knitting cam group 40. A pair of left and right switching cams 42 are provided for slightly advancing the x l of the knitting needles 2 that advance outward behind the cams 41.

The switching cam 42 is movable between a solid line position and a chain line position, and when the switching cam 42 is in the solid line position, it is removed in the direction of the chain line position when the knitting needle X, which acts from the outside, comes into contact with it.

A butt passage 43 is connected to the front end of the switching cam 42 at the solid line position, and the knitting needles passing through this N are sorted into two positions, front and back, by a second sorting member 44.

The member 44 is connected to a lowering cam 45 provided in the butt passage 43.
, a sorting cam 46 that is installed obliquely on the outside so that only low butts pass through the lower surface, and a guide cam 47 that guides the knitting needle butts that have passed under the lower surface of the cam backwards. It is adapted to be engaged with the sorting cam 46 and guided to the front.

In the above, when the switching cam 42 is set to the chain line position, all the knitting needle butts pass through the rear part of the butt passage 43, so the second sorting member 44 does not act at all.

Therefore, the knitting carriage changes to a simple knitting carriage in which only the knitting cam group 40 (pattern knitting cam mechanism) acts.

The second sorting member 44 is activated when performing two-color simultaneous knitting or other knitting patterns, and in that case, only the one at the rear of the carriage 39 in the direction of movement is activated.

This carriage 39 is provided with a second driving member 48 which projects from the rear edge and engages with the connecting hole 38 of the belt 10 when necessary.

The lower surface structure of the stitch transfer carriage 51 is as shown in FIG. 10, between the chevron-shaped advance cams 53 formed on both outer sides of the rear guard cam 520 and the horizontally long downward guide cams 55 formed on the outer sides of the front guard cam 540. A passage cam 56 is provided that constitutes a needle path X (front side) of the knitting needle butt that delivers the stitches and a needle path Y (rear side) of the knitting needle butt that receives the stitches,
Rear guard cams 52 on both outer sides of the forward cam 53
and a first sorting member 66 that distinguishes the knitting needles into two positions, front and rear, between the front guard cam 540 and the connecting hole 3 of the belt 10.
A first driving member 74 that engages with and connects the drive member 8 is provided.

The passage cam 56 is composed of a front cam body 58 and a rear cam body 59 arranged on both sides of a chevron-shaped center cam 57 provided on the front guard cam 54. A chevron-shaped protrusion is provided at the rear of both sides, and the corresponding inner side thereof is used as a backward cam 60 connected to the center cam 57, and each outer side is provided on each inner side of a rear cam body 59 placed laterally slightly behind the front end of the chevron-shaped forward cam 53. A backward cam 61 that slopes rearward from the front end of the forward cam 62 formed.
shall be.

The first sorting member 66 is arranged between a guide cam 63 extending outward from the rear cam body 59 and the linear edge of the chevron-shaped advance cam 53 at the rear thereof, and guides the knitting needle butts advanced by the cam 53 outward. A lowering cam 67 is installed in the passage 65, and a sorting cam 68 that passes through the lower bat is installed at the outer end of the passage 65 on the outside of the front part. Further, a guide cam 69 for guiding the knitting needle butt rearward is provided at the outer end of the sorting cam 68.

The above-mentioned stitch transfer carriage 51 is configured to pass the knitting needle 2a selected at the front among the adjacent knitting needles through the needle path X, and pass the knitting needle 2b selected at the rear through the needle path Y. The knitting needle 2a that has entered the X is passed through the front part of the front cam body 58, and is moved backward by the center cam 57 and the backward cam 60 on the rear side in the direction of movement.

The knitting needle 2b that has entered the needle path Y passes through the front part of the rear cam body 59 from the chevron-shaped forward cam 53, is advanced by the forward cam 62, and immediately retreats by the backward cam 61 to the same position as the knitting needle 2a.

Both knitting needles 2a and 2b, whose retracted positions are aligned, pass straight through the forward cam 53 on the rear side in the direction of movement and into the butt passage 65.
Then, the sorting member 66 sorts out the front knitting needles 2a and the rear knitting needles 2b.

Of course, the knitting needles 2a and 2b must not always be the same, and the selection is made by converting the needle signal row 17 on the signal recording card 11 every time this carriage 51 slides. will be discussed later.

As described above, the main carrying 51 carries the knitting needles 2a, which have passed through the needle path Y, to carry out the stitches suspended from the hooks of the knitting needles 2a, which have passed through the needle path X.
There is a stitch transfer mechanism that transfers to the hook b, and the structure can be completed for stitch transfer.

Specifically, the needle floating cam 70 lifts the front part of the knitting needle 2a above the comb teeth at the front end of the needle bed 1 over the part where the needle path X touches the front part of the front cam body 58 and the outside thereof.
, an auxiliary floating cam 71 that slightly floats the front part of the knitting needle 2b that advances on the front part of the rear cam body 59 including the forward cam 62 of the needle path Y; Needle moving force 72 crosses over or approaches the knitting needle 2b which is moving immediately in front of the knitting needle 2b, so that the hooks of both knitting needles oppose each other in the front and back, and the cam action of the cam 62 moves the stitch to the hook of the knitting needle 2b. A needle return cam 73 is installed which floats the knitting needle 2a that has been threaded above the comb teeth and returns it to its original position between the comb teeth by the elasticity of the needle.

The above symbols 70, 71, 72, and 73 constitute the stitch transfer carriage 510 and the stitch transfer mechanism.

The above-mentioned stitch transfer carriage 51 is equipped with a first drive member 74 that sequentially sends the signal recording card 11, which is a signal carrier of the present invention, row by row at the beginning of traveling in one direction on the needle bed 1. The structure shown in detail in the figure has a peculiarity in that it is installed in a symmetrical position as shown in Fig. 10.

As described above, the signal recording card 11 is fed by rotating the arrayed signal converting member in one direction by the feeding pawl 15 at the beginning of the rightward and leftward movement of the belt 10. When the carriage 51 is moved from the additional auxiliary rail 1a on the left side in FIG.
8 as shown in FIG. 2 to cause engagement.

This first drive member 74 is guided on both left and right sides and
．． It consists of a board that moves up and down as shown in Figure 11.
A pin 7 protruding from the upper surface of the carriage 51 as shown in the figure.
5 is planted, and a pine needle spring 77 is applied to the pin 75 and a fixed shaft 76 supported on the plywood of the carriage 510 to cause the first drive member 74 to protrude.

Reference numeral 78 denotes an operation plate long in the left and right direction provided on the plywood of the carriage 510, and has a pair of left and right movable elongated holes 7 that fit into the fixed shaft 76.
9 will be provided.

The operation plate 78 is further fitted with the pin 75 to move the first driving member 74 between a protruding position where it can engage in the connecting hole 38 of the belt 10 and a position where it retreats from the engagement as the pin 75 moves from side to side. A cam hole 80 having an oblique side is formed.

Reference numeral 82 denotes a rotary knob fitted on the fixed shaft 76, and a pinion 83 is provided which engages with a rack 81 bridged over the upper surface of the operating plate 78 to control the left and right movement of the operating plate 78.

The present invention provides a second sorting member 44 and a first sorting member 6 in both the knitting carriage 39 and the stitch transfer carriage 51.
6 and a second drive member 48 and a second drive member 74, respectively.

The former 44 and 66 work together with the signal recording card 11 provided on the needle bed 1, the signal reading unit 27, the scanning control wheel 19, the signal transmission rod 36, and the needle selection unit 5 to move the knitting needles 2 to two positions, front and back. The latter 48 and 74 are engaged with the belt 10, and as the cartridge moves, the card feed device of the needle bed 1, the feed pawl 15 that drives it, the feed drive lever 15a, etc. This constitutes a device for driving the array signal conversion member 12.

Of course, these first and second drive members 48 and 74 can be moved to a position where they do not produce a protrusion that engages with the belt 10, as described above, and in that case, the belt 10 is Therefore, the array signal member 12 is not driven and the signal recording card 12 (signal carrier) is not sent.

Since the operation of the knitting cam group 40 (pattern knitting cam mechanism) of the other knitting carriage 39 is conventionally well known, the operation will be explained below using the stitch transfer carriage 51 as a representative.

When the carriage 51 is in the permanent position shown in FIG. When it protrudes and moves on the needle bed 1 in the right direction in the figure, it engages the connecting hole 38 of the belt 10, causing the belt 10 to run, controlling the rotation of the rotating wheels 9, 9a, and moving the bevel gears 22. 23 rotates the scanning control wheel 19, and at the same time, at the beginning of 90 rotations of the rotating wheel, the clutch mechanism 25 is activated.
The positive rotation of the rotating shaft 24 is controlled by.

The rotating shaft 24 is first connected to the operating shaft 340 by the face cam 35.
The roller 34a is pushed down, the free end of the lever 33a of the shaft 33 and the clear rod 32 are lowered, the signal reading unit body 27 is pushed down, and the signal reading unit 28 and the signal transmission unit 29 are connected to the rotating drum 16.
and retreat below the scanning control wheel 19.

Subsequently, the feed pawl drive lever 15a is moved up and down by the face cam 26, the ratchet wheel 14 and the feed shaft 13 are advanced by a small angle by the upward movement of the feed pawl 15, and the signal recording card 11 is fed by the card feed device 12. That is, the column 17 of the card 110 needle selection signal is converted.

At the same time, the clear rod 32 is released from being pressed down by the seventh eighth cam 35, and each signal reading unit 27 is pushed up by the leaf spring 31.

However, those corresponding to the non-perforated part of the row 17 of the needle selection signal of the signal recording card 110 are prevented from being pushed up by contacting the bottom surface of the card, so only those corresponding to the perforated part rise and pass through the signal transmission part 29. plunges into the annular groove 20 of the scanning control wheel 19,
The scanning cam 21 rotating together with the wheel 19 sequentially generates oscillations centering on the signal reading section 28 to transmit the signal to the signal transmitting section 29.
and the needle selection body 5 connected thereto are moved in a direction that resists the elasticity of the spring 80. Therefore, the needle selection protrusion 6 of the needle selection body 5 connected to the hole of the needle selection signal row 17 belongs to it. knitting needle 2
Displaced midway between.

Then, when the undisplaced knitting needle 2 with the needle selection protrusion 6 facing downward enters the butt passage 65 and is pushed down by the lowering cam 67 of the sorting member 66, the shank is submerged under the lower surface of the needle selection protrusion 6 and is locked. As a result, a low butt is generated, the needle passes under the lower surface of the sorting cam 68, and is selected backward by the guiding cam 69 to become the knitting needle 2b.

Also, the knitting needle 2 that does not have the needle selection protrusion 6 downward (displaced knitting needle)
Even if it is pressed down by the lowering cam 67, it immediately floats up by the leaf spring 3 and is guided forward by the sorting cam 68 to become the knitting needle 2a.

The scanning control wheel 19 includes a signal reading body 27 and a signal transmission rod 36.
, the above-mentioned shaking or movement of the needle selection body 5 is repeated periodically, and the displacement of the needle selection body 5 is continued by the scanning cam 21 until the knitting needle 2 finishes passing through the butt passage 65 and the sorting cam 68. to effectively line the needle selection.

In the case of stitch transfer, the above needle selection is performed between two adjacent knitting needles 20, but for stitch transfer, the knitting needle that transfers the stitch to the hook of the adjacent needle is the knitting needle 2a, Even if all other knitting needles are used as knitting needle 2b, there is no problem in the transfer operation.

To transfer stitches using the stitch transfer carriage 51 of this embodiment, the above-mentioned needle selection is performed by moving the carriage in one direction, and by moving the carriage in the other direction, the knitting needle 2a is passed through the needle path X, and the knitting needle 2b is passed through the needle path Y. This is done through the following steps.

A detailed explanation of the functions of the passage cam 56 and the needle floating cam 70 to the needle return cam 73 of the stitch transfer mechanism will be omitted.

In the stitch transfer carriage 51, the knitting needles are sorted by a sorting member 66 at the front in the direction of movement, contrary to the above embodiment,
If stitch transfer is controlled at the rear part of the carriage, needle selection and stitch transfer can be performed continuously with one sliding movement of the same carriage.

When performing two-color simultaneous knitting or other pattern knitting with the needle selection action to the front and back positions of the knitting needles 20 in this embodiment, the second drive member 48 of the knitting carriage 39 is projected and moved. The carriage 39 is connected to the belt 10.
Implemented by using alone.

Furthermore, for lace knitting involving stitch transfer, both the stitch transfer carriage 51 and the knitting carriage 390 are used, with the first drive member 74 of the former protruding so as to be connectable to the belt 10, and the second drive member 48 of the latter retracted. The knitting cam group 40 is arranged to perform 1,000 knitting.

As a result of the above, the signal conversion action based on the feeding of the signal recording card 11 occurs only every time the stitch transfer carriage 510 slides on the needle bed 1.

The sliding includes the case in which the carriage is idle-slided from the left permanent position in Figure 1 to the right and enters actual operation when sliding from right to left, and from the right or left. Even when sliding,
There is a distinction between a sliding movement in which needle selection is performed by the first selection member 66 and a sliding movement in which stitch transfer is performed.

The row of needle selection signals 17 in the card 11 is required only during sliding for needle selection. Even when the signal recording card 11 is sent, the card 11 is created so that the row 17 of needle selection signals is omitted from the corresponding part of the signal reading section 28 of the signal reading section body 27.

Due to this deletion, the first sorting member 66 is substantially at rest.

The operation sequence of the stitch transfer carriage 51 and the knitting carriage 39 in lace knitting performed by the apparatus of the embodiment will be explained as follows with reference to FIG.

◎For three-stitch lace knitting (knitting in which the hooks of knitting needles 2a on both sides of a particular knitting needle 2b are suspended from the hook of a specific knitting needle 2b are transferred and then flat knitting is performed), both carriages are used in the following order: (Fig. 14 a-f).

(a) The stitch transfer carriage 51 is slid from left to right.

(The signal recording card 11 does not have the needle selection signal row 17, and the carriage 51 is idle sliding.) (b) The same carriage 51
(The signal card 11 is sent by the first drive member 74, and the row of needle selection signals 17 and the first selection member 66 move the knitting needles 2a and 2b back and forth. (c) The carriage 51 is moved from left to right to perform stitch transfer and needle selection.

(The signal card 11 is sent by the drive member 74, and regardless of this, the passage cam 56 and the needle floating cam 70 to the needle return cam 73 move the stitch from the knitting needle 2a adjacent to the left to the knitting needle 2b immediately to the right, and then (d) The carriage 51 is moved from right to left to transfer stitches. (The signal card 11 is sent by the first drive member 74, but the card does not have the needle selection signal row 17,
To the knitting needle 2b that received the stitch transfer in the step (C), stitch transfer is performed in an overlapping manner starting from the knitting needle 2a immediately to the right of the knitting needle 2b.

) Export, f) The knitting carriage 39 is slid from right to left and then from left to right to perform two stages of knitting using knitting yarn.

In addition to this, it is also possible to perform the three-in-one lace knitting by using the operating mode shown in FIGS. 15a-f.

◎For lace knitting of two stitches and one stitch (knitting in which 1,000 stitches are performed after transferring the stitch in which the hook of the knitting needle 2a adjacent to the knitting needle 2a is suspended from the hook of a specific knitting needle 2b), both carriages 51 and 39 are used, for example. If the knitting needle 2a is on the left, the knitting needles 2a are slid in the order of a=f in FIG. 16, and if they are on the right, the knitting needles 2a are slid in the order of a to d in FIG.

Therefore, regardless of whether the transfer mode is three-stitch-once or second-stitch-once, the transfer carriage 51 is always on the left side of the needle bed, and the knitting carriage 39 is on the right side for each section that has been transferred. Both of those carriages are 51,3.
Since the 9s are not mixed together, both of those 5s
With the simple operation of changing L39, you can perform the lace edition extremely easily.

As clarified from the above description, the first aspect of the present invention is to provide a stitch transfer carriage that can run independently on a needle bed, in addition to a knitting carriage that provides knitting motion to knitting needles arranged in rows on the needle bed. The stitch transfer carriage is equipped with the first sorting member, the stitch transfer mechanism, and the first drive member, the embodiments of which have been made clear in the above description, and the knitting carriage is equipped with the above-mentioned one as well. It is equipped with a second sorting member, an embodiment of which was made clear during the explanation, a pattern knitting cam mechanism, and a second driving member, so that either the stitch transfer carriage or the knitting carriage can be run on the needle bed. Also, the signal carrying member is driven by a functionally equivalent first driving member or a second driving member, and for the stitch transfer carriage, the first driving member is driven in cooperation with the first sorting member. It is activated to sort the knitting needles that are transferring stitches and the knitting needles that are being transferred into two positions after the knitting, and the knitting carriage is separated from the second sorting member only when knitting multicolor patterns using the pattern cam mechanism. This system operates a second driving member under cooperative motion to sort the necessary knitting needles into two positions, front and back.In particular, when using a stitch transfer carriage, the knitting needles must be placed in the front and rear positions in advance by hand. There is no need for sorting and sorting, and it can automatically perform knitting needle sorting using a signal carrying member, and can perform a unique function and effect of automatically transferring stitches, and it also replaces the conventional first driving member. There is no disadvantage as in the case where a carriage for transferring a single stitch is used alternately with a carriage for knitting for flat knitting.

Further, according to the second invention, the knitting needle is placed in the other position, that is, the same position as the knitting needle for stitch transfer, in the signal stage when stitch transfer is not required in connection with the travel of the stitch transfer carriage, so that the knitting needle is substantially in the same position as the knitting needle for stitch transfer. Since the stitch transfer carriage can be moved idly, the effect of the first invention can be further enhanced.
