Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a knitting machine in which a knitting mechanism is housed in a closed case.

[Prior Art] In a conventional knitting machine, a needle bed and a carriage that extend linearly from side to side are housed in a case.
During assembly, it was necessary to open the case and expose one floor and carriage.

[Problems to be Solved by the Invention] Therefore, in the conventional IN, the case is opened to expose the needle bed and carriage at the start of knitting, and the needle bed and carriage are opened again at the end of knitting or when the knitting is interrupted. They were forced to perform the extremely labor-intensive task of returning it to containment and closing the case. Moreover, since there is no space provided in the case to accommodate the fabric, the case cannot be closed when the knitting work is interrupted with the knitted fabric hanging on the knitting needles. For this reason,
When the knitting operation is interrupted, it is necessary to remove the knitted fabric from the needles one stitch at a time, and therefore, when the knitting operation is restarted, it is necessary to rehang the knitted fabric one stitch at a time on the knitting needles, which is extremely troublesome.

Moreover, during knitting work, every time the carriage performs knitting operations, a large amount of noise is generated, which not only causes a nuisance to the surrounding area, but also causes yarn dust and yarn waste to be scattered around or float in the air. In addition, there was a risk that children could come into contact with the moving carriage.

In addition, in conventional knitting machines, it is necessary to provide rails at both left and right ends of the needle bed to prevent the ↓ spear from falling off, so the needle bed is long from side to side. For this reason, in order to maintain the straightness of the needle bed so that it does not bend, the number of parts is increased by making the entire needle bed thicker, using a material with higher strength, or using many reinforcing materials. There were a lot of problems, and the production was time-consuming.

In particular, when the needle bed is made of synthetic resin, it is extremely difficult to achieve straightness, making manufacturing even more difficult.

As described above, since the needle bed is long from side to side, it requires a large installation space both when in use and when not in use, and is heavy and bulky, making it inconvenient to carry.

The purpose of this invention is to allow knitting to be carried out with the case closed, without having to open or close the case, take out or take out the needle bed or carriage, or attach or remove the stitches. Ti! can accommodate knitted fabrics, is convenient to carry and store, and is easy to make. 1i.

1. Means for Solving the Problem] In order to achieve the above object, in the first invention of the Koi application, the needle bed is formed in a cylindrical or conical shape, and the knitting needles are placed on the cylindrical or conical surface. They are arranged parallel to each other at predetermined intervals in the circumferential direction, and the needle bed, the knitting actuator, and the drive device are housed in a sealed case that can be opened and closed.

Further, in the second invention, a space for accommodating the knitted fabric is provided inside the airtight case, and a space forming part that shapes the space is configured to be expandable and retractable, so that the size of the knitted fabric accommodating space is made variable. ing.

[Function] Therefore, in the first invention, since the needle bed is cylindrical or circular and is housed in a sealed case, the overall size can be reduced and the size can be reduced, and the straightness can be improved. This eliminates the need for retaining parts or means for maintaining strength, and eliminates the need for a large installation space for use. Moreover, the noise leaking to the outside is extremely low, and there is no chance of old woolen items floating in the water.

Further, in the second invention, the @-shaped knitted fabric can be stored in the expandable storage space in the sealed case, and the whole can be made compact when it is not knitted, and the knitted fabric becomes longer as it is knitted. It can easily accommodate knitted fabrics.

[Embodiments] Hereinafter, embodiments embodying the present invention will be described based on the drawings.

Therefore, when feeding the yarn during back stitch knitting, regardless of the moving direction of the needle bed 20, the action of the seventh and eighth drive cams 160 and 161 causes the needle bed 2o to move toward the side in the moving direction with respect to the main needle 24. Kara field 20
The thread 76 is moved in the direction opposite to the moving direction (see FIG. 24 (9) and FIG. 25 (11)).

(Summary) The functions of the front stitch and back stitch have been explained above, but this lfi
In the machine, by switching the excitation of the solenoids 81 to S6, the positions of the levers corresponding to various cam grooves on the drive cam body 122 are switched, and by selecting and sizing the appropriate cam grooves, the winding stitch, tuck stitching, In addition to being able to perform various types of rAli such as stop stitching and slip stitching, it is also possible to perform needle bed feeding without knitting.

During knitting or work on the knitting machine, the needle bed 20, knitting actuating device 30, motor 124 constituting the drive device, etc. are housed in the sealed case 1 in a closed state. The noise generated by the rotation of the needle bed 20, the knitting operation of the knitting needles 24, 63, etc. can be reliably reduced from leaking to the outside, and the knitting work can be carried out quietly, as well as noise generated during the knitting operation. It is also possible to prevent lint and lint from scattering to the outside, making it hygienic to use. Further, since the movable parts such as the needle bed 20 and II needles 24, 63 are not exposed, it is possible to prevent children from touching the movable parts, and knitting work can be performed safely.

Furthermore, in the knitting machine of this example, the needle bed 20 has a cylindrical shape, and a large number of knitting needles 24 are arranged parallel to each other on the outer peripheral surface of the cylinder at predetermined intervals in the circumferential direction. Sufficient strength can be ensured without increasing the thickness of 20 or using many reinforcing materials, and
The entire length of the needle bed 20 in the circumferential direction can be finished with high precision, and the overall size of the needle bed 20 can be reduced, so that the entire knitting machine can be made smaller and lighter. Furthermore, since the needle bed 20 rotates and the knitting actuating device M30 is arranged at a fixed position, there is no need to secure a movement area for the i-forming actuating device 30, making it possible to further reduce the size and weight. . Therefore, the knitting machine can be easily installed without requiring a large space when in use, and can be easily carried and stored when not in use.

In addition, in this knitting machine, since the needle bed 20 rotates and the knitting actuator 130 is in a fixed position, the knitting actuator 30
Even if electrical components are installed on the top, the electrical components may be damaged due to vibration, or a special and expensive cable that is resistant to bending and tension may be used as the electrical cord between the electrical components and the board 15, etc. on the case 1. No need for it, you can use a regular electrical cord.

In addition, if a knitting problem occurs during knitting and you want to resolve it, or if you want to thread the rope yarn through the yarn slack absorbing cover 218 or the thread port 76 before knitting, As shown in FIG. 2, the engagement between the latch fitting 9 and the locking fitting 11 is released, the upper case 3 is rotated to the rear of the lower case 2, and the needle bed 20 and the knitting actuating device 3 are opened.
Open above 0. In this state, when the bed plate 40 is moved to the non-working position 07, which is a distance away from the needle bed 20, the knitting operation H
i! f 3 0 and the needle bed 207 are disengaged from the master 24, and at the same time, the engagement between the drive gear 31 and the driven gear 28 is released. Therefore, in this state, the needle bed 20 is manually rotated as desired, and the knitting operation device 3
It is possible to solve the problem by moving it to a position that does not correspond to 0, or to thread the knitting yarn 212, etc.

Then, after solving this problem or completing the threading operation, visually check the needle bed 20 while rotating it! ! As a result, the permanent magnet 27 is aligned with a reference position sensor (not shown), and the needle bed 20 is returned to its original position and rotated.
If the bed plate 40 is moved to the operating position close to the needle bed 20 and the sealed case 1 is closed as shown in FIG.
The lti creation operation can be restarted or started in the same manner as above.

During the knitting operation, the knitted fabric 32 is housed and suspended in the knitted fabric storage space 33 inside the needle bed 20, and when the hanging length of the knitted fabric 32 becomes long, the space forming member 35 is moved downwardly. By adjusting the drawer size, the knitted fabric 32 can be accommodated without getting in the way of the knitted fabric 32 and without applying a negative external force to the knitted fabric 32 against the knitting.

Furthermore, when the knitting machine is to be carried or stored after the knitting work is finished or at the interrupted position, the legs 5 are rotated to the folded position along the bottom surface of the lower case 2, as shown in FIG. By pushing the space forming member 35 upward through the through hole 34 and storing it within the needle bed 20, the entire knitting machine can be further downsized. In this case, even if the space forming member 35 is pushed up while the knitted fabric 32 is accommodated in the knitted fabric storage space 33, the knitted fabric 32 remains accommodated within the space forming member 35, and there is no problem. . Therefore, in autumn, the knitting machine can be easily carried by grasping the handle 12 provided on the upper surface of the upper case, and can also be easily stored even in a narrow space.

When knitting is interrupted, the knitted fabric 32 is stored in the knitted fabric storage space 35, so when carrying or storing the knitting machine, the knitted fabric 32 can be removed one stitch at a time from the main needles 24, or
There is no need for the very troublesome work of redoing A3 sheets one by one when restarting, and the cleaning work of rj A 戊 work and the preparation work for starting the organization work can be done in a short time, and the editing work can be done quickly. can be done extremely efficiently.

In addition, when transporting or storing this knitting machine, since the yarn slack absorbing device H218 is housed in the sealed case 1, the knitting yarn 212 must be removed from the yarn slack absorbing device #A 218, and the yarn slack absorbing device H218 must be There is no need to fold the device 218 into a stored state, and the knitting yarn 21 is attached to the yarn slack absorbing device H218.
2, the knitting yarn 212 may be cut from the yarn boggon 211 with a predetermined length of yarn end remaining through the yarn supply hole 210 on the bottom surface of the lower case 2. Then, when knitting work is restarted, the knitting yarn 212 extending from the yarn bobbin 211 is tied to the yarn end, and knitting can be started immediately. Therefore, in the same way as mentioned above, the cleaning work after knitting or the preparation work at the start of knitting can be done easily and in a short time.Furthermore, since the yarn slack absorbing device is not exposed outside the case, the overall It can be made to have a good appearance.

(Another Embodiment) Note that the present invention is not limited to the above-described embodiment; for example, the knitting needles 24 are provided on the inner peripheral surface of the cylindrical needle bed 20.
The needle bed 20 is formed into a conical shape, and the knitting needles 24 are arranged in parallel to each other at predetermined intervals in the circumferential direction on the outer or inner peripheral surface of the cone, or the needle bed 20 is fixed. so that the knitting work unit TL30 revolves around the needle bed 20,
Alternatively, the structure of each part may be arbitrarily changed without departing from the spirit of the present invention, such as by moving both the nail bed 20 and the knitting operation device @30 so that relative movement occurs between them. It is also possible to do so.

(Effect of the invention) Since this invention is configured as explained above,
Qin has excellent effects such as:

First, the needles are formed in a cylindrical or conical shape, and each knitting needle is arranged parallel to each other at predetermined intervals in the circumferential direction on the cylindrical or conical surface, so the thickness of the needle bed can be increased. It is possible to secure sufficient strong jetting without using a lot of reinforcing materials, and it is possible to reduce material costs, processing costs, and morning equipment costs. The entire length of one row in the f2 direction can be machined to a high M degree, and the entire knitting machine including the needle bed can be made smaller and lighter, requiring a large space when using the knitting machine. In addition to being easy to install, it is also easy to transport and store when not in use.

Further, the needle bed, the knitting actuating device that imparts a knitting action to each knitting needle, and the driving device that causes relative movement between the needle bed and the rA or actuating device are housed in a closed case that can be opened and closed. As a result, the noise generated due to the relative movement between the needle bed and the knitting or actuating device and the knitting operation of the knitting needles during knitting work is prevented from leaking outside, and the knitting work can be performed quietly. It prevents yarn dust and yarn waste generated during knitting operations from scattering outside, making it hygienic to use, and preventing children from coming into contact with exposed knitting needles, knitting actuating devices, etc. , it can be handled safely, and furthermore, there is no need to open and close the case at the beginning and end of use, making it possible to work efficiently.

Furthermore, since a fukuji storage space is provided inside each bed, the knitted fabric can be stored in the sealed case without getting in the way, and when knitting is interrupted or restarted, the knitted fabric can be removed one stitch at a time from the knitting needles, or the knitted fabric can be hung. There is no need for troublesome work such as repair, and the organization work can be carried out efficiently. In addition, since the space forming member forming the knitted fabric storage space is expandable and retractable, when carrying and storing the fabric, the fabric is compact and convenient to carry and store without getting in the way.
