Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a storage rotating body and a needle selection rotating body that rotate in association with the sliding of a carriage, and a needle selection signal applying device applies a needle selection signal to the storage rotating body and stores a memorized selection signal. The needle selection signal is transmitted to the needle selection piece of the needle selection rotary body to perform needle selection, and the needle selection signal transmitted to the needle selection piece is also released as a signal that is linked to a drive cam provided on the center of the carriage. The present invention relates to a needle selection device for a hand knitting machine that is released by a member.

Conventionally, in the above-mentioned needle selection device (for example, 24 needle selection), the memory of the memory piece of the memory rotor and the memory of the needle selection piece of the needle selection rotor are performed separately. This is accomplished by a memory release piece fixed on the carriage around the rotating body, and the latter release is performed by a signal release member interlocked with the drive cam as described above. The storage rotor and the needle selection rotor rotate together in conjunction with the sliding movement of the carriage, and when the storage rotor rotates once while acting on the needle selection signal giving device, each needle selection piece (24 pieces) is sequentially A needle selection signal is given and stored, and
The needle selection signal stored in each memory piece is transmitted to the corresponding needle selection piece of the needle selection rotor when the storage rotor has made a half revolution from the time it was stored, and immediately thereafter, it is automatically transmitted to the corresponding needle selection piece by the memory release piece. It was about to be lifted.

Therefore, even after both rotating bodies have rotated in a predetermined direction and the needle selection signal has been applied to the memory rotating body, all the data stored in the memory rotating body must be rotated by at least half a turn in the same direction. The needle selection signal is not transmitted to the needle selection rotor.

For this reason, even though the needle selection signal has been applied to the storage rotor, the length of the carriage is changed only by turning both rotors at least half a rotation, that is, the length carriage corresponds to the row spacing of 12 to 20 knitting needles. If the needle is not slid, the desired needle selection cannot be performed, which is not only troublesome but also inefficient.

In view of the above-mentioned conventional drawbacks, the present invention provides a hand knitting machine that can perform desired needle selection even if the carriage is reversely slid immediately after the needle selection signal application device finishes applying the needle selection signal. The present invention aims to provide a needle selection device.

The needle selection device of the present invention includes a storage rotor having a plurality of memory pieces radially mounted thereon, and a needle selection rotor having the same number of needle selection pieces radially mounted on both sides of the carriage, respectively. As the carriage travels, the needle selection signal stored in the memory piece by the needle selection signal applying device is sequentially transmitted to the needle selection piece as the storage rotor and the needle selection rotor rotate. A drive cam that is driven by engaging with the operating cam of the needle selection signal applying device is attached to the carriage, and the carriage rotates in conjunction with the drive cam to release the needle selection on the needle selection piece. In the needle selection device for a hand knitting machine, the needle selection device is equipped with a signal release member that releases the needle selection signal of the needle selection piece by engaging the needle selection cam part. The present invention is characterized in that a memory release cam portion is provided which simultaneously engages with the memory piece and releases the memory when the needle selection piece is engaged.

The illustrated embodiment will be described below.

Reference numeral 1 denotes a carriage mounted on a needle bed 2 so as to be able to slide left and right.A storage rotor 3 and a needle selection rotor 4 are mounted on both left and right sides of the carriage so as to face each other in the front and back. The needle selection signal read by the signal reading piece 5 of the needle selection signal applying device (not shown) provided at It is transmitted to the needle selection piece 7.

The signal reading piece 5 reads the needle selection signals (24 selections) of a predetermined signal stage of a signal card (not shown) in which the needle selection signals constituting a required unit pattern are displayed in multiple stages using perforated parts and non-perforated parts. There are 24 signals, which is the same as the number of signals in one signal stage, and each one is supported rotatably in the front and back direction and attached to the memory piece in relation to the rotation of the storage rotor 3. They are arranged in a row in the moving direction of 3.

The storage rotor 3 has the same number of storage pieces 6 as the signal reading pieces 5 (24
The lower gear 8 is mounted on the rear upright wall 2' of the needle bed 2 in relation to the sliding movement of the carriage 1. As it engages with the forming rack 9 and rotates in a predetermined direction, the memory piece 6 moves to a substantially vertical outer position (dashed line in Figure 2).
By engaging the upper engaging portion 6a with the corresponding signal reading piece 5, each signal reading piece 5 is sequentially pushed rearward. In this case, when the signal reading piece 5 is facing the perforated part of the needle selection signal, the signal reading piece 5 is displaced to the rear position (dashed line in Figure 2), and as a result, it corresponds to the signal reading piece 5. The memory piece 6 continues to maintain its outer position.

Further, when the non-perforated portions of the needle selection signals are facing each other, backward movement is prevented and the signal reading piece 5 maintains the front position.
As a result, the memory piece 6 is pushed in the opposite direction and is displaced to a downwardly inclined inner position (solid line in FIG. 2).

In this way, the 24-hour needle selection signal displayed on one signal stage of the signal card is sequentially read by the signal reading piece 5 by one rotation of the storage rotary body 3, and each corresponding storage piece 6 is It is memorized by taking either an internal position or an external position.

The needle selection rotating body 4 also includes upper and lower engaging portions 7.
The same number of needle selection pieces 7 having a and 7b as the memory pieces 6 are mounted in the same state, and the lower gear 10 meshes with the gear 8 to rotate integrally with the memory rotating body 3.
When the needle selection piece 7 is in the outer position (solid line in Figure 2) and the corresponding memory piece 6 is in the inner position, the upper engaging part 7a engages with the lower engaging part 6b and is pushed. Displaced to the inner position (dashed line in the figure), memory piece 6
is in the outer position, the upper engaging portion 7 is attached to the lower engaging portion 6b.
Maintain the outer position (solid line in the figure) without engaging a.

In this case, when the needle selection piece 7 is in the inner position, the lower engaging part 7b does not engage with the butt 11' of the knitting needle 11, and when it is in the outer position, the lower engaging part 7b engages with the butt 11' and moves forward. Push.

In this way, the 24 needle selection signals stored in the storage rotor 3 are such that each memory piece 6 faces the corresponding needle selection piece 7 in sequence, and each of the needle selection pieces 7 indicates whether the needle selection piece 7 is in the inner position or the outer position. The knitting needle 11 is transmitted in two positions, front and rear, by the needle selection signal.

In this case, the needle selection signal stored in the storage rotary body 3 is transmitted from the memory piece 6 to the corresponding needle selection piece 7 when the storage rotation body 3 has rotated half a revolution since the time when it was stored. Therefore, the 24 needle selection signals stored in the memory rotary body 3 are the first to
The 12th needle selection signal is transmitted to the needle selection rotary body 4, and when both rotary bodies 3 and 4 make another half turn, the 13th to 24th needle selection signals are transmitted to the needle selection rotary body 4. .

Reference numeral 12 denotes a signal release member which is rotatably supported on the carriage 1 by a shaft 13 inside the storage rotor 3 and needle selection rotor 4, and is used to move the needle selection piece 7 from the needle selection action position to the non-action position. In addition to the needle selection release cam 12b for releasing the needle selection, it has a memory release cam part 12a for releasing the memory of the memory piece 6. The signal release member 12 is normally located at the position shown by the solid line in FIGS. 1 and 3, that is, the needle selection release cam portion 12
b does not engage with the upper engaging portion 7a of the needle selection piece 7, and the memory release cam portion 12a is held in an inactive position where it does not engage with the lower end portion 6c of the memory piece 6. However, when rotated as described later, the signal release member 12 causes its needle selection release cam portion 12b to engage with the upper engagement portion 7a of the needle selection piece 7, and at the same time, the signal release member 12 engages its needle selection release cam portion 12b with the upper engagement portion 7a of the needle selection piece 7. is displaced to the operating position (dashed line in FIG. 3) where it engages with the lower end 6c of the memory piece 7.

Reference numeral 14 denotes a drive cam, which is rotatably supported by a shaft 15 on the central rear side of the carriage 1, and is connected to the signal release member 12 by connecting rods 16, 16 mounted on both left and right sides. , 16, the engagement portion 14' is always
is urged to protrude rearward of the carriage 1 to maintain a neutral position in which both signal release members 12 are placed in an inactive position.

Reference numeral 18 denotes an operating cam for operating the drive cam 14, which is fixed at the lower front side of the needle selection signal applying device over a length that is approximately the same as the length of the row of signal reading pieces 5, and is related to the sliding movement of the carriage 1. Then, the engaging portion 14' of the drive cam 14 is engaged, and the drive cam 14 is thereby rotated clockwise or counterclockwise (FIG. 1) against the bias of the spring 17.

In this case, when the drive cam 14 rotates clockwise, only the connecting rod 16 on the right side (FIG. 1) operates, and the signal release member 12 connected thereto is displaced to the operating position, and also in the counterclockwise direction. When rotated, only the left connecting rod 16 operates and the signal release member 12 connected to it is displaced to the operating position.When the carriage 1 is slid left and right, the needle selection rotation in the forward direction of movement occurs. While the required needle selection is performed by the body 4, just before the memory rotary body 3 at the rear in the traveling direction reaches the needle selection signal giving device, both rotary bodies 3, 3 and 4, 4
Since the drive cam 14 located between is rotated in a predetermined direction by the actuation cam 18, the signal release members 12 corresponding to both the rear rotors 3 and 4 are displaced to the operating position, and the signal release members 12 corresponding to the rear rotors 3 and 4 are moved to the operating position. The needle selection signal of the previous knitting stage held by is released, that is, the needle selection piece 7 is displaced from the needle selection action position to the non-action position, and at the same time, the memory of the memory piece 6 is released, and then the needle selection signal is given. The device applies a needle selection signal for the next knitting stage to the storage rotary body 3 and the needle selection rotary body 4 at the rear in the direction of travel, and is set in a relationship to be stored therein.

However, as shown in Figure 1, the carriage 1
As the needle moves to the right, a needle selection signal is applied from the needle selection signal application device to the storage rotating body 3 at the rear in the direction of travel, and the 24th point
It is assumed that the needle selection signal is similarly read and stored in the 24th memory piece 7' by the 24th signal reading piece 5'.

At this time, the 1st to 12th needle selection signals among the 24 needle selection signals stored in the storage rotary body 3 are the first to 12th needle selection signals located on the right half circumference (FIG. 1) of the needle selection rotary body 4. ~12th Needle selection signals are transmitted to each needle selection piece 7, respectively, but the 13th to 24th needle selection signals located on the left half circumference of the storage rotor 3 (see the same figure) are still transmitted to the corresponding needle selection pieces 7. It has not been. At this time, the drive cam 14
has already been removed from the actuating cam 18, and the left signal release member 12 is held in the inactive position.

Then, when the carriage 1 is reversed (to the left), the storage rotor 3 rotates clockwise (Fig. 1) and the needle selection rotor 4 rotates once counterclockwise, and during the latter half rotation, The number stored in the storage rotating body 3
The 13th to 24th needle selection signals are transmitted to the corresponding needle selection pieces 7 in reverse order, and as a result, all of the needle selection signals stored in the storage rotor 3 are transmitted to the corresponding needle selections of the needle selection rotor 4. It is transmitted to piece 6.

In this case, since the memory piece 6 and the needle selection piece 7 are not released, each memory piece 6 of the memory rotary body 3 is The memory piece 6, which faces the signal reading piece 5 and stores the 1st to 12th needle selection signals during the first half rotation, again faces the corresponding needle selection piece 7, but in both cases, the application and Since the needle selection signals held are the same, there is no problem with the needle selection action.

In this way, the required needle selection is performed by the needle selection rotating body 4 located in front of the traveling direction in relation to the leftward movement of the carriage 1. Further, even when the carriage 1 moves to the right, the required needle selection is performed by the needle selection rotary body 4 located in front of the vehicle in the traveling direction, similar to the case when the carriage 1 moves to the left.

As is clear from the above description, according to the present invention, even if the sliding direction of the carriage is changed immediately after the application of the needle selection signal to the storage rotor is completed, all the applied needle selection signals are transferred to the needle selection rotation. Therefore, even though the provision of the needle selection signal in the conventional case has been completed, at least the knitting needle 12 is transmitted to the needle selection rotary body in order to transmit the needle selection signal to the needle selection rotating body. There is no need to continuously slide a carriage of ~20 lengths, and the sliding operation of the carriage can be reduced by at least that much, contributing to improved efficiency in knitting work. Further, a signal release member that releases the needle selection piece of the needle selection rotary body is provided with a memory release cam portion that releases the memory piece of the memory rotation body,
Since the needle selection piece and the memory piece are released at the same time by the same signal release member, there is no need to separately provide a dedicated memory release mechanism for releasing the memory piece, which simplifies the mechanism. , both release operations can be performed accurately.
