Further, in the carriage of such a knitting machine, a first switching operation member for switching the auxiliary cam to each of the first and second positions, and a first switching operation member for switching the tuck cam to each of the first and second positions. A second selection operation member for operation is respectively provided.

[Problems to be Solved by the Invention] By the way, in the above-mentioned conventional device, when performing flat knitting, the first switching operation member switches the auxiliary cam to the first one.
This is done by changing the position and opening the knitting path.

When performing tuck knitting, the first switching operation member switches the auxiliary cam to the second position to close the knitting passage and opens the non-knitting passage, while the second selection operation member moves the tuck cam to the first position. This is done by switching the position and opening the tack passage.

Furthermore, when performing a sliding glance, as mentioned above,
The first switching operating member switches the auxiliary cam to the second position, while the second selection operating member switches the tack cam to the second position, closing the tuck passage and listening to the unformed passage. This is done under the condition of cam arrangement.

In particular, when changing the stitch structure, etc. for each row or several rows, each time the first switching operation member and the second selection operation member are individually operated to adjust the auxiliary cam and the tuck cam, respectively. It is necessary to switch between the first and second positions corresponding to the organization of the train.

For this reason, the switching operation of each cam requires a lot of time and effort, and not only is it a troublesome operation, but also there is a problem that sometimes the switching operation of the cams is mistaken, resulting in defects in stitch formation.

, a first operating member that switches the auxiliary cam to each of the first and second positions, a first switching member that switches the auxiliary cam to each of the first and second positions separately from the first operating member, and a second switching member that switches the tack cam to each of the first and second positions. A knitting machine in which a carriage is provided with a second operation member that is switched to the first and second positions through the needle bed, and the carriage is mounted on a needle bed so as to be slidable from side to side. When the tack cam is switched from the position to the second operation position to the second position where the tack passage is closed and the non-formed passage is opened, the auxiliary cam moves the formation passage without switching the first operating member. said second position so as to be switched to a second position opening the unorganized passageway;
An operating member and a first switching member are connected to each other, and an operating member for operating the second operating member when the carriage slides left and right is located outside the knitting section of the needle bed. The actuating member is disposed so as to be displaceable between an operating position where it acts on the second operating member and an inactive position where it does not act on the second operating member, and the direction of displacement of the operating member is perpendicular to the displacement plane of the switching operation direction of the second operating member. It has a configuration set in the direction.

(not shown). Here, if the cam switching command is stored in the eight-wheel drive device, the electromagnet 79 is excited based on the signal from the sensor. Then, the attracting piece 74c of the first actuating member 74 is attracted by the seven yokes 79a of the electromagnets, and the first J member 74 is held in the operating position.

After the rubber-like carriage 8 is slid to the left to a predetermined position on the extension frame 70 of the rubber-like needle bed 5, the carriage 8
When the rubber carriage 8 slides to the right in the opposite direction, the operating piece 52 of the second operating member 49 on the right side of the rubber carriage 8 comes into contact with the operating piece 77 of the first operating member 74 held at the operating position.

As the rubber-like carriage 8 continues to slide to the right, the second operating member 49 on the right side is moved by the first operating member 74 to the first operating member 49 .
The operating position is switched to the second operating position shown by the solid line in FIG. The second operating member 49 on the right side passes through the first operating member 74 while being retracted and rotated by a predetermined angle from the second operating position as shown by the chain line in FIG.

Further, the second operating member 49 on the left side of the rubber-like carriage 8 is
J3 in FIG. 18 passes through the second actuating member 85 and the first actuating member 74 while being retracted and rotated from the first operating position shown by the chain line to the retracted position shown by the solid line.

The second operating member 49 on the right side of the rubber-like carriage 8
By being placed in the operation position, the cam arrangement becomes a cam arrangement with zero edges as shown in FIG. Note that since the second operating member 49 on the left side is disposed at the first operating position δ, the auxiliary cam 25 on the left side is moved to the first operating position under the action of the elastic force of the spring 34.
It will be placed in position. However, the butt of the knitting needles guided from the knitting preparation passage A-A on the right side of the rubber machine key 1r rigidity 8 to the non-knitting passage B-B is attached to the auxiliary cam 25 on the left side.
While opening against the elastic force of the spring, it is introduced into the formation preparation passage A-8 on the left side. Therefore, when sliding the rubber-like carriage 8 to the right on the rubber-like needle bed 5, if only the second operation member 49 on the right side of the carriage 8 is placed in the second operation position, zero-slip knitting is possible. Become.

When the rubber-like carriage 8 is moved through the knitting section of the rubber-like needle bed 5 toward the extension frame 70 on the right side thereof, the second operating member 49 on the right side of the carriage 8 is moved to the right side in the inactive position. After passing the first operating member 74, the second
While the actuating member 85 is tilted against the elastic force of the return spring 88, it passes through the vJ member 85 in the second operation.

Further, the second operating member 49 on the left side of the carriage 8 is a second
It passes only the first actuating member 74 in the inactive position without reaching the actuating member 85.

As shown in FIG. When the first actuating member 74 is slid to the operating position, the interlocking rod 78 is rotated by the interlocking cam 83 of the kitriage 8 against the elastic force of the spring 82, and the first actuating member 74 is moved to the operating position.

On the other hand, when the rubber machine carriage 8 is slid to a predetermined position on the extension frame 70 on the right side of the rubber-like needle bed 5, a signal from a sensor (not shown) that detects the presence or absence of the carriage 8 is transmitted to a machine driving device (not shown). sent to. Here, if the cam switching command is not stored in the tfAn drive device, the electromagnet 79 is kept in a non-energized state.

After the rubber-like carriage 8 is slid to a predetermined position on the extension frame 7o on the right side of the rubber-like needle bed 5, the carriage 8
When actuated in the opposite direction to the left, the operating piece 52 of the second operating member 49 on the right side of the rubber-like carriage 8 moves to the second operating member 85.
The actuating piece 87 comes into contact with the actuating piece 87.

With the subsequent sliding of the rubber-like carriage 8 to the left, the second operating member 49 on the right side is moved from the second operating position to the first operating position by the second operating member 85, as shown by the solid line in FIG.
V) can be changed to the operating position.

The right second operating member 49 passes through the second operating member 85 while being retracted and rotated by a predetermined angle from the first operating position as shown by the chain line in FIG.

Also, 1 to the left of the Kireriji 8! As the actuating cam 83 is removed from the actuated piece 81 of the interlocking rod 78, the moving rod 78 is rotated by the elastic force of the spring 82, as shown in FIG. 1 actuating member 74 is moved to the inactive position. Therefore, the second operating member 49 on the left side of the rubber press clamp 8 passes through the 'f51 operating member 74 while remaining in the first operating position.

Therefore, the left and right cylinders 2 operating members 49 of the rubber machine carriage 8
are both placed in the first operating position, so the cam arrangement of the carriage 8 is the original cam arrangement, 'TJ', the flat cam arrangement as shown in Fig. 1, or the cam arrangement as shown in Fig. 14. The cam arrangement is returned to the tuck version.

As described above, by sliding the rubber dawn carriage 8 to both the left and right extension frames 70 on the rubber machine needle bed 5, the second operating member 49 of the carriage 8 can be moved from the first operating position to the second operating position. Or the second t! It is possible to automatically switch from the first operation position to the first operation position. In this way, 1st, 21st! ! Cut the working member 49 to the first and second operating positions 8 [by rotating it, you can change from flat or tuck knitting to 1 hem knitting, or change from 1 slip knitting to the original flat knitting or tuck knitting. It is possible to automate cam switching when

Further, the first actuating member 74 is disposed so as to be movable only in the backward direction perpendicular to the rotational displacement plane with the support shaft 51 of the second operating member 49 as a fulcrum, and is independent of the operating position U. It is adapted to be displaced to the working position. Therefore, when the second operating member 49 contacts the first operating member 74 and the second operating member 49 is switched from the first operating position to the second operating position, the load of the contact causes the first operating member to 74 is actively prevented from being displaced from the active position to the inactive position. As a result, even if the electromagnet 79 with a small capacity a (magnetic force) is used, the first actuating member 74 is
The second operating member 49 can be reliably switched from the first operating position to the second operating position.

In addition, in the said Example, the case of the rubber wa machine which was equipped with this machine and the rubber slough at right angles was illustrated, but it is not limited to this. For example, in a knitting machine equipped with a single needle bed and a carriage installed on the needle bed so as to be able to slide from side to side, the auxiliary cam 25 and the tack cam 28 are the first, second and third cams, respectively.
Any type of carriage that can be switched between the second positions can be used.

[Effects of the Invention] As described above, according to the present invention, the second operating member can be moved from the first operating position by manual operation regardless of whether the cam arrangement is for flat knitting or for tuck knitting. By switching to the second operating position, the tack cam is moved to the second operating position.
The second position can be changed to
The auxiliary cam can be switched to the second position by the first switching member connected to the operating member, and thereby the cam arrangement can be changed to one-slip cam arrangement.

Contrary to the above, by switching the second operating member from the second operating position to the first operating position with a single hand motion, the cam arrangement can be changed to the original flat knitting or tuck knitting.

As a result, when changing the knitting due to changes in the stitch structure, etc., it is possible to switch the cam by hand! The IJJ operation can be performed easily, quickly and accurately, and has the effect of preventing poor knitting of stitches.

Moreover, according to the present invention, by sliding the carriage that slides left and right on the needle bed to the outside of the knitting section, the actuating member located at the action position of the needle bed acts on the second operating member of the carriage. As a result, the second operating member can be selectively operated, so that cam switching can be automated.

Furthermore, since the displacement direction of the operating member between the operating position and the non-operating position is set perpendicular to the displacement plane of the switching operation direction of the second operating member, the operating member in the operating position is When acting on the second actuating member, this is prevented from being displaced towards the inactive position. Therefore, the second operating member can be reliably switched and operated by the operating member in the operating position.

In addition, when there is no need to switch the second operating member of the carriage, the operating member is displaced to the inactive position, so that the second operating member is not switched and operated, so that the cam arrangement of the carriage can be caused unexpectedly. It is possible to prevent the problem of switching to
