Description

Technical Field

[0001] The present invention relates to the field of flat knitting machines, and particularly to a process for knitting gloves without waste yarn on a flat knitting machine. Background Art

[0002] At present, when knitting glove fabrics on a flat knitting machine, the glove is knitted finger by finger. When a transfer stitch pattern is required for a finger, the first and second rows of the fabric need to be turned needles or transferred stitches. It is necessary to knit a section of waste yarn (when turning needles or transferring stitches, a certain downward pressure tension must be applied to the loops of the fabric, otherwise the loops will be lifted by the knitting needles and the action cannot be achieved). Then, a roller or a bottom plate is used to provide a certain tension to the loops to achieve turning needles or transferring stitches.

[0003] Therefore, when knitting fabrics such as gloves on a flat knitting machine, a certain amount of waste yarn will be left at the starting position, which not only wastes yarn but also requires manual trimming in subsequent steps, taking time and effort.

[0004] Therefore, the inventor of the present invention conducts further research and develops a process for knitting gloves without waste yarn on a flat knitting machine, and this case is thus generated. Summary of the Invention

[0005] The purpose of the present invention is to provide a process for knitting gloves without waste yarn on a flat knitting machine, which avoids the generation of waste yarn during flat knitting, improves production efficiency, and reduces costs.

[0006] In order to achieve the above purpose, the technical solution of the present invention is as follows:

[0007] A process for knitting gloves without waste yarn on a flat knitting machine is achieved in the following way:

[0008] Each time a glove finger is knitted, after the first row of loops is formed, a loop-hooking device drives a loop-hooking part to rise to the position of the loops, controls the loop-hooking part to hook the loops, the loop-hooking part descends after hooking the loops, and gradually descends during the subsequent knitting process to keep the loops under tension. After knitting the preset target, the loop-hooking part withdraws.

[0009] To achieve the above invention purpose, it is necessary to ensure that the loop-hooking part has the ability to lift and lower, but the lifting and lowering drive structure itself does not constitute an absolute limitation. The loop-hooking part needs to match the loops themselves, not be too short or too thick, and during the process of maintaining tension, the loop-hooking part cannot cause the loops to fall off (i.e., maintain tension).

[0010] Further, the hooking of the loops by the loop-hooking part is achieved through a clamping and opening action.

[0011] By using an action similar to that of a clip or a pneumatic gripper to grab the loops, the hooking of the loops can be ensured.

[0012] Furthermore, the wire-hooking part includes two hook claws, which are in a needle-like structure and are overall in an S shape or a Z shape. The ends of the hook claws intersect with each other during the opening and closing process.

[0013] During the opening and closing process, the hook claws keep the coil in the hooked state by closing.

[0014] Furthermore, the wire-hooking part is arranged on the lifting plate, and the lifting plate is linked with the lifting motor through a rack.

[0015] The whole wire-hooking part is lifted by driving the rack with the lifting motor.

[0016] Furthermore, the wire-hooking part includes a lifting plate, and a connecting piece is arranged on the lifting plate. One end of the connecting piece is linked with the hook claw, and the other end is linked with the hook claw motor.

[0017] The connecting piece can adopt common connection methods such as a gear set, a rack and pinion, a pulley, etc.

[0018] Furthermore, a groove is formed on the lifting plate, a slide rail is arranged in the groove, a groove is formed on one side of one end of the slide rail, and one end of the hook claw is arranged in the groove. At the same time, the hook claw is pivotally connected to the lifting plate.

[0019] The slide rail is driven to move by the hook claw motor, so as to drive the hook claw linked with the slide rail to swing. With the cooperation of the lifting motor driving the lifting plate, the first row of coils can be hooked.

[0020] Furthermore, two symmetrical hook claws are arranged on the lifting plate, and the hook claws are both arranged in the grooves at the ends of the slide rail.

[0021] After adopting the above scheme, compared with the prior art, the present invention has the following advantages:

[0022] The first row of coils is hooked by the hook claws of the wire-hooking part to form tension, so as to prevent the coils from being lifted by the knitting needles, and the subsequent woven fabric does not need to be subjected to waste yarn cutting treatment, saving yarn consumption and manual processing.

[0027] LABEL DESCRIPTION

[0028] Hook claw 1, hook claw motor 11, lifting plate 2, slide rail 21, rack 3, lifting motor 4,

[0029] Front needle plate 5, rear needle plate 6. Specific implementation mode

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] A knitting glove process for flat knitting machines without waste yarn is used to solve the problem of waste yarn generated during the knitting of flat knitting machines in the prior art, and it is mainly realized in the following ways:

[0032] Between the front needle plate 5 and the rear needle plate 6 of the flat knitting machine (generally, the one in the front of the machine is the front needle plate 5, and the one in the rear is the rear needle plate 6. Here, the dotted line schematic diagram is used as a reference for distinction), as Figure 1 、 Figure 2 shown, a pair of hook claws 1 for hooking coils are provided. The hook claws 1 are arranged in an S shape or a Z shape, and the end in contact with the coils is a needle-like structure. The bent part at the other end is pivotally connected to the lifting plate 2 and is embedded in the grooves on both sides of the end of the slide rail 21. The slide rail 21 is also located in the chute of the lifting plate 2 and is driven by the hook claw motor 11 to move in the chute, so that the hook claws 1 swing, and the hook claws 1 hook the coils during the swinging process (refer to Figure 3 、 4 ).

[0033] The lifting plate 2 and the hook claw motor 11 are arranged on the rack 3 through a lifting seat. The rack 3 meshes with the driving gear of the lifting motor 4. By driving the rack 3 to lift and lower through the lifting motor 4, the hook claws 1 can be lifted or lowered. That is, when the hook claws 1 are in the Figure 3 state, they rise to the first coil that has been knitted, and are driven to close by the hook claw motor 11 to hook the first coil. At this time, the hook claws 1 are in the Figure 4 state, and then the lifting motor 4 drives the hook claws 1 to lower, so that the first coil maintains tension to facilitate subsequent knitting.

[0034] The lifting motor 4 and the rack 3 can also be replaced with technical solutions such as a lifting cylinder. This is a conventional replacement and does not require creative labor.

[0035] The process is as follows: When the first row of coils is knitted between the needle beds (because the finger ends of the gloves are closed, the front and rear needle plates need to knit symmetrically, and then cylindrical knitting is carried out), the hook claws 1 are driven to rise by the lifting motor 4. At this time, the two hook claws need to be kept in the state as shown in Figure 1In the open state shown, when the hook claw inserts into the coil in the first row of coils, the hook claw closes under the drive of the hook claw motor 11 to hook the coil, and then descends to a certain extent under the drive of the lifting motor so that the coil can maintain tension relative to the subsequent coils. And as the subsequent coils are knitted, the hook claw needs to gradually descend to keep the tension within a reasonable range at all times.

[0036] For glove knitting, each time a glove is knitted, it starts from a single finger. When the first finger is knitted, the method is as described above. After one finger is knitted, the hook claw withdraws from the coil and is driven to the knitting area of the next finger, repeating the above actions. At this time, only the entire wire hooking device needs to be combined with the slide rail and the lateral drive to achieve this.

[0037] A single hook claw can still achieve the above functions, or make certain changes to the structure of the hook claw itself, and make a conventional replacement of the connection method between the hook claw motor and the hook claw, and still achieve the above purpose. This embodiment only introduces the preferred solution and is not limited thereto. At the same time, words such as "up, down, left, right, middle" involved in the present invention are only for reference and are not absolutely limited. Any non-substantive modification using the present invention shall fall within the scope of infringement of the protection scope of the present invention.
