Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a carriage that guides the butts of a group of working knitting needles involved in knitting a fabric to two different butt paths by sliding on a needle bed to perform pattern knitting or stitch transfer, etc. A dormant needle sensing cam that detects the butt of a dormant knitting needle in a knitting halt state following the knitting needle at the end of the working knitting needle group; The present invention relates to an end needle actuating device for a hand knitting machine, which includes an end needle actuating cam that moves the butt of a knitting needle to a position where it can be introduced into a specific one of the two butt passages.

For example, in the case of two-color simultaneous knitting, this type of device selects the knitting needles at both the left and right ends of the knitted fabric and always supplies colored knitting yarn to these end knitting needles.
It has the advantage of being able to prevent so-called vertical cracking of the knitted fabric, and in the case of stitch transfer, it is possible to prevent so-called dropped stitches by selecting the knitting needles at both the left and right ends of the knitted fabric as those for stitch succession. There are advantages that can be achieved.

However, in pattern knitting such as two-color simultaneous knitting and other tatsu knitting, so-called needleless knitting is performed in which one or more knitting needles in a certain knitting section are rested in a resting position that is not involved in knitting. Even when knitting or knitting that does not require the selection of end knitting needles, there is a disadvantage that the working knitting needles adjacent to the knitting needles at the rest position or the end knitting needles are sorted out and the predetermined pattern etc. is distorted. be.

However, in order to eliminate the above-mentioned drawbacks, the present invention specifically provides a system in which the resting needle sensing cam and the end needle operating cam are separately movable for sorting out end knitting needles, and that both of them are movable. Provided between the cams is a contact/separation member that can be switched between a state in which both cams are connected so as to be integrally interlocked when sorting end knitting needles, and a state in which the connection is released and movement of both is allowed. In the case of the needle removal knitting or when there is no need to sort out the end knitting needles, the above-mentioned defects can be reliably removed by breaking the integral interlocking relationship between the two cams by a simple switching operation of the contact/separation member. This is what I did.

By doing so, the movable piece 60 engages with the predetermined engagement surface 53 of the end needle operating cam 48, and the rest needle sensing cam 38 and the end needle operating cam 48 are brought into a connected state.

By sliding the knitting carriage 19, two-color simultaneous knitting with needle selection action, tatsu knitting, etc. are performed, and as shown in FIG. When the butt of the first end knitting needle 7 faces the end needle actuating cam 48 a little before the needle selection cam 35, the knitting needle 7 at the rest position V adjacent to that knitting needle 7
The butt of the end knitting needle 7 is moved forward to select the needle because the rest needle sensing cam 38 is placed in the forward non-engaging position and the end needle actuating cam 48 is placed in the active position. Sorted into aisle G. Immediately after this sorting, the butt of the knitting needle 7 at the rest position V comes off the rest needle sensing cam 38, so both cams 38
8, 48 are moved to a rearward position as shown on the left side of FIG. 2 by the action of a tension spring 57. Therefore, the butt of the subsequent knitting needle group is determined by the needle selection cam 3.
5, the signals are sorted forward and backward according to the recorded signals on the signal card 11. However, when the butt of the last end knitting needle 7 of the active knitting needle section faces the end needle actuating cam 48, the butt of the knitting needle 7 in the rest position V adjacent to that knitting needle 7 advances the rest needle sensing cam 38 and The butt of the end knitting needle 7 is sorted into the needle selection path G in order to place the needle actuating cam 48 in the operating position.

On the other hand, in the case of knitting that does not require selection of the end knitting needles 7, for example, knitting such as so-called needleless knitting or flat knitting in which one or several knitting needles in the active knitting needle section are placed at the rest position V, In advance, by rotating the operation part 61 of the contact/separation member 58 clockwise using a transfer needle or a flat head screwdriver, the movable piece 60 is removed from the predetermined engagement surface 53, and both cams 38, 48 are removed.
By this, the end needle actuating cam 48 is placed in the inactive position due to the springing action of the tension spring 57, and the rest needle sensing cam 38 is placed in the inactive position due to the springing action of the coil spring 47. Therefore, they are respectively placed in the disengaged position (see FIG. 5).

By sliding the knitting carriage 19 in this state to knit, neither of the two cams 38, 48 will interfere with the progress of the butts of the knitting needles 7.

A second embodiment embodying the present invention will be described below with reference to FIGS. 6 to 14. Note that the same names and symbols as those in the first embodiment will be used for parts common to the first embodiment, and the explanation thereof will be omitted.

A stepped portion 94 formed on the front side of the holder is provided. The end needle actuating cam 87 has its guide plate 89 fitted into the fitting groove 82 of the rest needle sensing cam 79, and is held between the bottom surface of the groove 82 and the lower surface of the race carriage 68. The end needle actuating piece 88 is moved to the rear operating position (the rearmost position is the rearmost position) where the end needle actuating piece 88 is arranged to protrude below the lowering cam 75. (the position where the hanging piece 92 abuts the rear sliding leg 70) and the position where the upright piece 91 abuts the front edge of the through hole 90 and the end needle actuating piece 88 retracts forward from the lower side of the lowering cam 75. and the working position. Reference numeral 95 denotes a coil spring with relatively low elasticity, which is inserted into the spring insertion groove 96 of the rear sliding leg 70 and interposed between the spring hanging piece 93 of the end needle operating cam 87 and the rear hanging part of the race carriage 68. In particular, the end needle actuating cam 87 is urged forward only in the operating position.

In the figure, reference numeral 97 denotes a small contacting and separating member, which is inserted into the opening groove 82 of the rest needle sensing cam 79 and has a column-shaped main body portion 98 that is in contact with the holding piece 85, and extends horizontally from the upper end of this portion 98. Movable piece 99 to take out
An operating portion 100 is formed on the lower end surface of the main body portion 98, and two places on the circumferential surface of the main body portion 98 are cut out to form the holding piece 85.
Due to the self-retaining elasticity of the body portion 98, the body portion 98 is held in the following two positions. By operating the operation part 100 of the approaching/separating member 97 with a transfer needle or a small flat head screwdriver and aligning it with one positioning mark 101 cut out in the sensing cam piece 80 as shown in FIG. The member 97 is held in the connecting position, and in this position, the open end of the movable piece 99 engages the specific engagement surface 92A, which is the rear surface of the hanging piece 92 of the end needle actuating cam 87.
At the same time, the guide piece 83 of the idle needle sensing cam 79 and the stepped portion 94 of the end needle operating cam 87 are engaged, and the two cams 79 and 87 are integrally connected so as to be interlocked. Further, the operating section 100 is rotated by 90 degrees (the one on the right in FIG. 7 is rotated clockwise, and the one on the left is rotated counterclockwise).
By aligning the position mark 102 with the other alignment mark 102, the contact/separation member 97 is held in the uncoupled position, and in this position, both of the cams 79, 8

On the front side of the lace carriage 68, there are a well-known needle raising cam 103 and an auxiliary needle raising cam 10, which raise the front part of the front knitting needle during stitch transfer, bend it laterally, and control the latch.
4. A needle return cam 105, a needle lateral movement cam 106, a bullet plate, etc. are provided. 107 is race carriage 68
A knitted fabric presser ring is pivotally attached to the left and right sides of the front lower surface of the knitted fabric by stepped screws 108, and is constructed in the form of a disc made of rubber or a soft flexible synthetic resin material such as rubber, and has a knitting presser ring on the upper surface of the circumferential side. A large number of small protrusions 109 that can engage with the comb teeth 6 and the knitted fabric are arranged. This knitted fabric presser ring 107 is particularly effective in holding down lace knitted fabrics. With conventional brushes installed in the shape of a stock, the tips of the brushes often fit into the holes of the knitted lace fabric, making the holding action of the knitted fabric uncertain. However, by using the knitted fabric presser ring 107 having the above-described shape, the above-mentioned conventional drawbacks can be overcome.

In addition, 110 in the figure is a needle selection eraser that prevents the continuous eight knitting needles 7 from being subjected to needle selection action.
It is integrally formed of a synthetic resin material, and its lower surface is provided with a number of positioning pieces 111 that can be fitted into the butt guide grooves of the butt guide plate 4 of the needle bed 1, and its upper surface is provided with the rest needle detection cam. An actuating cam 112 is formed that moves the sensing cam piece 80 of 79 toward the rearward non-engaging position and holds it at that moving position. Reference numeral 113 denotes a small needle selection and erasing body different from the needle selection and erasing body 110, which prevents the four consecutive needle selections 7 from being subjected to needle selection action, and has a positioning piece 114 on its lower surface. An operating cam 115 is formed on the upper surface.

This embodiment is configured as described above.

Therefore, in the stitch transfer action, the contact/separation member 97
By placing and holding the end knitting needles 7 in the connected position as shown in FIG.
8, the butt of the knitting needle 7 at the rest position V adjacent to that knitting needle 7 holds the rest needle sensing cam 79 at the rear non-engaged position side, so the butt of the end knitting needle 7 The actuating piece 88 moves it to the rear preparation path R and sorts it out. Thus, the butts of the subsequent knitting needles 7 move straight and are subjected to the action of the needle selection cam 76. However, when the butt of the last end knitting needle 7 faces the end needle actuating piece 88, the butt of the knitting needle 7 in the rest position V adjacent to that knitting needle 7 moves the rest needle sensing cam 79 toward the disengaged position. Therefore, the butts of the end knitting needles 7 are moved to the rear preparation path R and sorted by the end needle actuating piece 88.

In this way, the knitting needles 7 at both left and right ends of the active knitting needle section
By sorting the butts backwards, it is possible to reliably prevent the so-called dropped stitch phenomenon.

On the other hand, when the end knitting needles 7 are not sorted as described above, for example, when knitting a pattern in which a pattern such as two-color simultaneous knitting and a lace pattern are mixed, the knitting carriage 19 is moved by the lace carriage 68. When performing only the needle selection function for pattern knitting, the contact/separation member 97 may be placed in the unconnected position using a transfer needle or a small flat head screwdriver. As a result, the sorting action of the end knitting needles 7 is not performed.

In addition, when a pattern such as a lace pattern or a color pattern is not included in a certain area of the patterned fabric, the needle selection eraser is placed on the rear side of the butt guide plate 4 of the needle bed 1 corresponding to that area. 110 or 113 and the contact/separation member at the connecting position, and then by sliding the race carriage 68,
While the selection of the end knitting needles 7 is carried out as described above,
As shown in FIGS. 13 and 14, when the needle selection erasing body 110 or 113 corresponds to the idle needle sensing cam 79, the needle selection erasing body 110 or 113
In order to position and hold the idle needle sensing cam 79 at the rear non-engaging position side, the operating cam 112 or 115 of the needle selector 110 or 113 has the butts of the eight or four knitting needle groups corresponding to the end needles. Operating cam 87
are sorted into the preparation path R and guided to the knitting preparation position W. Therefore, in the pattern knitting of the next course, the pattern does not appear in the portion of the knitted fabric corresponding to those eight or four knitting needles 7, and the pattern is erased.

As described in detail above, the present invention includes a carriage for pattern knitting, stitch transfer, etc., which includes a resting needle detection cam that detects the butt of a resting knitting needle, and an end of a group of working knitting needles that is connected to the detection of the resting knitting needle. Targeting an end needle actuating device that is provided with an end needle actuating cam that moves the butt of a knitting needle to a position where it can be introduced into a specific one of two butt passages, it is particularly applicable to At each position of engagement and non-engagement with the knitting needles,
The end needle actuating cam is movably arranged to act on and do not act on the butt of the working knitting needle, and between the two cams, the resting needle sensing cam is arranged by engagement with the butt of the resting knitting needle. and a connected state in which the end needle actuating cam is connected together with the end needle operating cam from the inactive position to the active position when the cam moves from the engaged position to the non-engaging position, and the connected state in which the two are connected together. A contact/separation member is provided that can be released and switched to a non-coupled state in which the two are allowed to move separately.

Therefore, by connecting the two cams by the contact/separation member, it is possible not only to sort out the butts of the end knitting needles, but also to sort out the butts of the end knitting needles, especially in the case of needle removal knitting or when it is necessary to sort out the end knitting needles. If not, by a simple operation of switching the contact/separation member to the uncoupled state, the connection between the two cams can be severed, and the action of the end needle actuating cam can be nullified. It is possible to reliably eliminate the drawbacks of the conventional method mentioned at the beginning.
