Abstract

The present invention provides a device and working method for automatically loading and unloading a cloth roll from a double-width warp knitting machine optical axis, belonging to the field of textile technology. The device includes a guide rail bracket, and an optical axis mechanical claw is installed on the guide rail bracket. Not only can the cloth roll optical axis with a friction roller PVC tube automatically slide to the cloth roll active roller position, but as the diameter of the cloth roll on the friction roller PVC tube increases, the cloth roll optical axis and the optical axis mechanical claw also rise until the cloth roll is completed. After the cloth roll is completed, the cloth roll unloading cylinder can push the cloth roll along the cloth roll unloading auxiliary plate to the cloth roll AGV vehicle group. Thereafter, the cloth roll AGV vehicle group moves in the opposite direction with the cloth roll.

It can be seen that the present invention can realize the automatic loading and unloading of the cloth roll optical axis and the automatic unloading of the double cloth roll, which can reduce labor costs, reduce labor intensity, and improve production efficiency.

Description

Technical Field

[0001] The invention belongs to the field of textile technology, and in particular relates to a device and a working method for automatically loading an optical shaft and automatically unloading a cloth roll of a double-width warp knitting machine. Background Art

[0002] A knitted fabric is formed by simultaneously winding one or several groups of parallel yarns onto all the working needles of the warp feeding machine. This method is called warp knitting, the fabric is called warp knitted fabric, and the machine that completes this warp knitting is called a warp knitting machine.

[0003] The double-width warp knitting machine is a relatively large warp knitting machine that can produce two cloth rolls at the same time. After it completes the winding operation of the fabric at the winding station, the two cloth rolls need to be removed from the winding station and enter the unloading station before the cloth roll unloading operation can be carried out. The cloth rolls can only be transported to the next process after the cloth rolls are unloaded.

[0004] At present, the entire process of the winding work of the double-width warp knitting machine is as follows: (1) Two workers put two friction roller PVC tubes onto the cloth winding optical shaft; (2) Lift the cloth winding optical shaft and slide it down along the cloth winding optical shaft guide track and place it on the cloth winding active roller; (3) Manually roll the cloth head onto the friction roller PVC tube and press it onto the cloth winding active roller, start weaving and winding; (4) After the cloth roll is rolled, two workers push the cloth transfer cart to the front of the machine, then drag the cloth roll to the cart, manually cut the cloth, drag away the cloth transfer cart, pull out the center cloth winding optical shaft, and repeat the above steps. The workers are time-consuming and labor-intensive when operating the two cloth rolls produced by the double-width warp knitting machine, with low efficiency, high labor costs and heavy burden on the workers, which affects the company's benefits. In addition, the cloth rolls are not limited during the winding process and are prone to deviation. Summary of the Invention

[0007] Furthermore, cloth winding optical axis guide rails are symmetrically arranged on both sides of the warp knitting machine frame, and the front of the cloth winding optical axis guide rails faces the output direction of the warp knitting machine frame. A cloth winding active roller is arranged below the cloth winding optical axis guide rails, and both ends of the cloth winding active roller are connected to the warp knitting machine frame.

[0008] Furthermore, cloth roll unloading cylinders are symmetrically arranged on both sides of the warp knitting machine frame, and the cloth roll unloading cylinders are located on the rear side of the cloth roll optical axis guide track, and the output end of the cloth roll unloading cylinder faces the output direction of the warp knitting machine frame.

[0009] Furthermore, a moving handle is provided on the top of the guide rail bracket; baffles are provided on both sides of the optical axis mechanical claw to prevent the double cloth rolls formed on both sides from being squeezed toward the middle after the cloth is rolled up, and a groove for accommodating the cloth rolling optical axis is provided at the bottom end of the baffle. The groove accommodates and limits the cloth rolling optical axis, and the upper end of the baffle is fixed to both sides of the slider, and a spring damping shock-absorbing block is installed at the end of the guide rail to prevent excessive vibration when the optical axis mechanical claw reaches the lowest position.

[0010] Furthermore, the guide rail bracket is bent and includes a vertical mounting frame, a horizontal extension frame and a vertical hinged frame connected in sequence. The guide rail is fixed on the vertical mounting frame, and the bottom of the vertical hinged frame is hinged to the vertical plate of the warp knitting machine frame.

[0011] Furthermore, a circular knife cloth cutting machine track is provided on the cloth roll unloading machine auxiliary plate.

[0012] Furthermore, the cloth roll unloading auxiliary plate is tilted and is located at one end of the warp knitting machine frame higher than one end of the cloth roll AGV vehicle group.

[0013] Furthermore, the surfaces of the first cloth roll AGV and the second cloth roll AGV are both concave in design, which facilitates the placement and positioning of the cloth rolls.

[0014] The present invention also provides a working method of a device for automatically loading an optical shaft and automatically unloading a cloth roll of a double-width warp knitting machine, comprising the following steps:

[0015] S1. After the optical axis mechanical claw grabs the cloth winding optical axis, two friction roller PVC tubes are placed on the cloth winding optical axis from both sides, respectively contacting the baffles; initially, the optical axis mechanical claw grabs the cloth winding optical axis and places the cloth winding optical axis at the lowest part along the cloth winding optical axis guide track, so that the friction roller PVC tubes mounted on the cloth winding optical axis contact the cloth winding active roller, and the cloth winding optical axis is put on the machine;

[0016] S2. The cloth-winding active roller starts to roll, and the friction roller PVC tube is driven by the cloth-winding active roller to wind up the cloth. As the diameter of the cloth roll increases, the cloth-winding optical axis rises along the cloth-winding optical axis guide track, and at the same time, the optical axis mechanical claw rises on the guide track.

[0017] S3. After the double cloth rolls are sleeved on the friction roller PVC tubes on both sides of the cloth rolling optical axis, the cloth roll unloading cylinders on both sides push the two cloth rolls along the cloth roll unloading auxiliary plates to the first cloth roll AGV and the second cloth roll AGV parked on the output side of the warp knitting machine frame. At this time, the guide rail bracket and the optical axis mechanical claw also rotate to the gap between the first cloth roll AGV and the second cloth roll AGV, realizing the double cloth roll unloading;

[0018] S4: Push the circular knife cloth cutting machine along the circular knife cloth cutting machine track from left to right to complete the cloth cutting work, so that the cloth rolls on the first cloth roll AGV and the second cloth roll AGV are separated from the cloth on the cloth roll active roller;

[0019] S5. After the cutting work is completed, the first cloth roll AGV and the second cloth roll AGV respectively move in opposite directions with the cloth rolls. Since the optical axis mechanical claw clamps the cloth roll optical axis, the cloth roll optical axis is separated from the cloth roll and the friction roller PVC tube. Then, two new friction roller PVC tubes are manually inserted and the moving handle at the end of the guide rail bracket is pushed to move the optical axis mechanical claw together with the cloth roll optical axis to the initial position, so that the cloth roll optical axis is put on the machine for the next round of work.

[0020] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0021] The guide rail bracket of the present invention, combined with the cloth roll AGV vehicle, enables automatic loading of the cloth roll shaft and automatic unloading of double cloth rolls. The shaft gripper, mounted on the guide rail bracket and in a freely sliding state, not only automatically slides the cloth roll shaft with the friction roller PVC tube to the active cloth roll position, but also, as the diameter of the cloth roll on the friction roller PVC tube increases, the shaft and the shaft gripper holding it rise accordingly until the cloth roll is completed. This process does not require any drive device to control the height of the rise. In addition, the installed cloth roll unloading cylinder can push the cloth roll along the cloth roll unloading auxiliary plate to the cloth roll AGV vehicle group in front of the warp knitting machine frame after the cloth is rolled. At this time, the guide rail bracket, cloth roll optical shaft and the friction roller PVC pipes on both sides of the cloth roll optical shaft are also moved to the cloth roll AGV vehicle group. After that, the first cloth roll AGV and the second cloth roll AGV respectively move in opposite directions with the cloth rolls. Since the optical shaft mechanical claw clamps the cloth roll optical shaft, the cloth roll optical shaft is separated from the cloth roll and the friction roller PVC pipe, realizing the automatic unloading of double cloth rolls.

[0022] It can be seen that the present invention can realize the functions of automatic loading of the cloth rolling shaft and automatic unloading of double cloth rolls, etc. It has a simple and compact structure and is easy to operate, which can reduce labor costs, reduce labor intensity, and improve production efficiency.
