Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized by relatively moving a needle bed in which a large number of knitting needles are arranged in a row, and a knitting operation device that applies a knitting action to each knitting needle. This relates to a knitting machine that performs knitting. [Prior art] As a conventional knitting machine of this type, for example, the Japanese Patent Publication No. 63-4
A configuration as shown in Japanese Patent No. 6183 is known.

In this knitting machine, a large number of knitting needles are arranged in rows on a horizontally long flat needle bed extending in the left-right direction, and on the needle bed there is a needle actuating body for imparting a knitting action to each knitting needle, A carriage serving as an editing actuating device equipped with an actuating cam etc. for actuating the actuating body is mounted so as to be slidable in the left and right direction, and the actuating cam is rotated by a drive device including a motor supported by the carriage. , while the carriage is moved by one arrangement pitch of the knitting needles by the action of one of the operating cams, the knitting needles are moved by one arrangement pitch of the knitting needles through the needle actuating body by the action of the other cam.
It is organized and operated book by book.

In addition, in this am, the needle bed is foldable and oval, and a cover body is attached to the rear open edge of the needle bed so that it can be opened and closed.When using the am, the cover body is opened and the needle bed is opened. Knitting or operation is performed with the knitting machine extended from the folded state and the surface of the needle bed and carriage exposed, and when the knitting machine is not in use, the needle bed is folded and the cover is retracted to the closed position on the needle bed. It is designed to be able to be transported and stored. Further, in this knitting machine, a yarn slack absorbing device for absorbing slack in the knitting yarn by a spring action is attached to the inner surface of the cover so as to be movable between a use position and a storage position via a thread take-up pin. When using the knitting machine, one cover is opened and the thread take-up bar is raised and rotated to place the thread slack absorbing device in the use position.When mtlA is not in use, the thread take-up bar is moved along the inner surface of the cover. The thread slack absorbing device is placed in the retracted position within the cover by rotating it to the laid-down position. [Problems to be solved by the invention] However, this conventional knitting machine had the following various problems. First, since the needle bed is shaped like a horizontally long flat plate that extends in the left-right direction, it is necessary to make the needle bed thicker and ensure greater bending strength so that the needle bed does not bend unnecessarily.
In addition to increasing material costs, processing costs, and assembly equipment costs, it was extremely difficult to maintain straightness accuracy over the entire length of the needle bed. In particular, when the needle bed is molded from a synthetic resin material, it is difficult to ensure bending strength and straightness accuracy, making processing difficult. In addition, since the needle bed is horizontally long, a large installation space is required when the knitting machine is in use, and the entire machine becomes large when not in use, making transportation and storage inconvenient. Furthermore, when using the knitting machine, the cover is rotated to the rear of the needle bed to expose the surfaces of the needle bed and carriage during knitting or other operations. The noise generated by the knitting operation is transmitted directly to the outside, which is very unpleasant.The yarn dust generated during the knitting operation is scattered outside, which is unhygienic.Furthermore, children are exposed to exposed knitting needles, etc. It was dangerous because there was a risk of contact. In addition, the cover body had to be opened and closed when starting and ending use of the m-machine, making preparation and clean-up work extremely troublesome. Furthermore, when starting and finishing use of the knitting machine, it is necessary to move the thread slack absorbing device between the use position and the storage position on the cover by raising and lowering the thread take-up pin. When the slack absorbing device is placed in the use position, it is necessary to pass the knitting yarn through the device, and when it is moved to the storage position, it is necessary to remove the silk thread from the device, which requires a great deal of preparation and cleanup work. There were problems in that it was troublesome and time-consuming, and the appearance was ruined. This invention was made by focusing on the problems existing in the prior art as described above, and its first purpose is to ensure sufficient strength without increasing the thickness of the needle bed. This makes it possible to reduce material costs, processing costs, and assembly equipment costs, and it is also possible to process the needle bed with high precision over the entire length in the direction in which the knitting needles are arranged. To provide a knitting machine that can be made smaller and lighter overall, can be easily installed without requiring a large space when in use, and can be easily transported and stored when not in use. ．． A second object of the present invention is to prevent the noise generated by the relative movement between the needle bed and the knitting actuating device and the knitting operation of the knitting needles from leaking outside during the knitting work. Not only can it be done quietly, it also prevents the thread dust generated during the mnemonic operation from scattering outside, making it hygienic to use, and preventing children from coming into contact with exposed knitting needles, etc. To provide a knitting machine that can be handled safely, and furthermore, it is not necessary to open and close the cover at the beginning and end of use, and preparation work and cleanup work can be easily performed. It's about doing. Furthermore, the third object of the present invention is to eliminate the need to move the thread slack absorbing device between the use position and the storage position when starting and finishing the use of the mill, and to move the thread slack absorption device to the use position or the storage position. There is no need to thread the silk thread into or remove the thread from the device each time the device is moved or placed, and the silk thread can be kept threaded through the thread slack absorbing device, reducing preparation and cleanup work. The objective is to provide a knitting machine that can perform knitting in a short time and easily. [Means for Solving the Problems] In order to achieve the above object, the present invention includes a needle bed in which a large number of knitting needles are arranged in a row, and a needle bed arranged in the immediate vicinity of the needle bed, and a needle bed for each knitting needle. a knitting actuating device that imparts a knitting motion to the knitting needle; and a knitting actuating device that moves at least one of the needle bed and the knitting actuating device to create a relative relationship between the two so that the knitting action is sequentially applied to each of the knitting needles. In a knitting machine comprising a drive device that causes movement, the needle bed is formed into 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. The needle bed, knitting actuating device, and drive device are housed in a closed case that can be opened and closed, and a thread slack absorbing device for absorbing slack in the silk thread is provided inside the closed case. [Function] When performing knitting work on the above-mentioned TS machine, the needle bed, knitting actuator, and drive device are housed in a closed case, and the needle bed, knitting actuator, and drive device are housed in a closed case. With the yarn slack absorbing device still disposed, the needle bed and the knitting actuating device are moved relative to each other by the drive device, and the knitting actuating device causes the knitting needles on the needle bed to be threaded one by one. Therefore, the knitting work can be performed quietly, hygienically, and safely. In addition, when transporting or storing the knitting machine after knitting work has been completed or interrupted, the airtight case must be closed again, the knitting yarn must be removed from the yarn slack absorbing device, and the yarn slack absorbing device must be folded into the stored state. There is no need to do this, and it can be transported immediately in its used state.

This figure shows the state in which the knitted fabric container 24 is pulled out to the usage position below the main case 2. In this state, when the operating cam body 37 of the knitting actuating device 35 is rotated by the rotation of the motor 38, the rotating body 44, the driving gear 47, and the driven gear 20 are rotated by the action of a predetermined cam on the operating cam body 37. While the needle bed 13 is rotated by one row pitch of the main needles 18, one main needle 18 on the needle bed 13 or the opposing sub-needle 32 is knitted every time the needle bed 13 rotates by one row pitch. , one stitch is knitted, and this operation is repeated in sequence to knit one course. Next, the direction of rotation of the needle bed 13 is reversed, and the next course is knitted. In this way, a predetermined knitted fabric K is created. The knitted fabric K hangs down from the hook portion of the main needle 18 into the needle bed 13 and is housed in the silk fabric container 24. As described above, during the knitting work of the knitting machine, the needle bed 13, the knitting actuating device 35, the motor 38 constituting the drive device, etc. remain housed in the sealed case 1 in the closed state. , Needle bed 1 during knitting work
3 and the knitting operation of the knitting needles 18 and 32 can be reliably prevented from leaking to the outside, allowing the knitting work to be carried out quietly, as well as reducing the amount of yarn generated during the knitting operation. It can also prevent dust from scattering to the outside, allowing for sanitary use. Also, knitting needle 18
．． Since the movable parts such as 32 are not exposed, it is possible to prevent children from touching the movable parts, and knitting work can be carried out safely. Further, in the knitting machine of this embodiment, the needle bed 13 has a cylindrical shape, and a large number of needles 18 are arranged parallel to each other at predetermined intervals in the circumferential direction on the outer peripheral surface of the cylinder. Sufficient bending strength can be secured without increasing the thickness of the needle bed 13, and the entire length of the needle bed 13 in the circumferential direction can be finished with high precision. It can be made smaller and lighter. Therefore, when the knitting machine is in use, it can be easily installed without requiring a large space, and it can also be easily transported and stored when not in use. In addition, when a knitting trouble occurs during knitting work and it is desired to resolve the trouble, or when threading the knitting yarn Y through the yarn slack absorbing device 57 or the thread opening 34 is carried out prior to knitting work. As shown in FIG.
Open the upper part of 5. In this state, attach the support plate 29 to the needle bed 13.
When the needle actuator 36 of the knitting actuator 35 is disengaged from the main needle 18 on the needle bed 13, the drive gear 47 on the support plate 29 side and the needle bed are disengaged. The meshing with the driven gear 20 on the gear 13 is released. Therefore,
In this state, the needle bed 13 can be arbitrarily rotated manually to move the knitting troubled part to a position that does not correspond to the knitting actuating device 35 to solve the trouble, or to thread the knitting yarn Y, etc. Can be done. After this trouble is resolved or the threading operation is completed, while rotating the needle bed 13, visually check to align the magnet 21 with a reference position sensor (not shown), and return the needle bed 13 to its original position. At the same time, when the support plate 29 is moved to the operating position close to the needle bed 13, the actuating body 31 is placed in a position where it engages with the main needle l8, as shown in FIG. 47 is driven gear 2
It is meshed with 0. In this state, if the cover 4 of the sealed case 1 is rotated to the closed position on the main case 2, and the clamp body 6 and the locking body 7 are engaged to clamp it in the closed position, the knitting or operation will be resumed in the same manner as above. Or you can start. Furthermore, if you want to transport or store the knitting machine after the knitting work is finished or while the knitting work is interrupted, the support legs 9 should be rotated to the folded position along the bottom surface of the main case 2, as shown in FIG. , if the knitted fabric storage body 24 is pushed upward from the through hole 22 and stored in the storage recess 23 of the needle bed 13, mw
The entire system can be further downsized. Therefore, in this state, the knitting machine can be easily transported by grasping the handle 5 provided on the top surface of the cover 4, and can also be easily stored even in a narrow space. In addition, when transporting or storing this knitting machine, since the yarn slack absorber 1f57 is housed in the closed gage 1, the knitting yarn Y must be removed from the yarn slack absorber 257, and the yarn slack absorber 57 must be removed. There is no need to fold the knitting yarn into a stored state, and with the knitting yarn Y passed through the yarn slack absorbing device 57, a predetermined length of yarn end is left through the yarn supply hole 5l on the bottom of the main case 2, and knitting is performed. All you have to do is cut the thread Y from the thread bobbin B. Then, when the knitting work is restarted, the knitting yarn Y extending from the yarn bobbin B is tied to the yarn end, and knitting can be started immediately. Therefore, the cleaning work after the completion of the formation and the preparation work at the start of the formation can be carried out easily and in a short time. Note that the present invention is not limited to the configuration of the embodiment described above, and for example, the knitting needles 18 may be arranged in rows on the inner peripheral surface of the cylindrical needle bed 13, or the needle bed 13 may be formed into a conical shape. It is also possible to arbitrarily change and embody the structure of each part without departing from the spirit of the present invention, such as by arranging knitting needles 18 on the outer or inner circumferential surface of the cone. [Effect of the invention] This invention is ovalized as explained above, so
It has the following excellent effects. First, the needle bed has 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 bending strength even without the knitting needle, reduce material costs, processing costs, and assembly equipment costs, and machine the needle bed with high precision over the entire length in the direction in which the knitting needles are arranged. In addition, the entire knitting machine including the needle bed can be made smaller and lighter, and the knitting machine can be easily installed without requiring a large space when in use, and can be easily transported and stored when not in use. It's easy to do. Further, the needle bed, the knitting or actuating device that imparts a knitting action to each knitting needle, and the drive device that causes relative movement between the needle bed and the knitting actuating device are housed in a sealed case that can be opened and closed. This prevents the noise generated by the relative movement between the needle bed and the knitting actuator and the knitting operation of the knitting needles from leaking outside, allowing the knitting work to be carried out quietly. At the same time, it prevents yarn dust generated during knitting operations from scattering outside, making it hygienic to use, and preventing children from coming into contact with exposed knitting needles, etc., making them safe to handle. Furthermore, there is no need to open and close the cover at the beginning and end of use, making preparation work and clean-up work easier. Furthermore, since a thread slack absorbing device that absorbs the slack of the silk thread by a spring action is provided inside the sealed case, the I.
There is no need to move the yarn slack absorbing device between the use position and storage position when starting and finishing use of the lA machine, and each time the yarn slack absorption device is moved to the use position or storage position, On the other hand, there is no need to thread the silk thread or remove the thread, and the state in which the knitting thread remains threaded through the thread slack absorbing device can be maintained, 11! Preparation and clean-up work can be done quickly and easily, and the appearance can also be improved.
