Description

Technical Field

[0001] This invention relates to the field of circular knitting machines, specifically to an automatic fabric roll feeding method for a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have seen rapid development due to their numerous loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0003] The circular knitting machine mainly consists of three parts: the yarn feeding mechanism, the knitting mechanism, and the tensioning mechanism. During installation, the machine is fixed by a lower frame, which is located inside the machine door. The fabric winding machine, as the specific implementation mechanism of the tensioning mechanism, is located on the frame inside the machine door. The fabric is wound onto the winding rollers of the fabric winding machine inside the machine door. Currently, the fabric roll unloading process of the circular knitting machine is as follows: when the outer diameter of the fabric roll wound by the fabric winding machine reaches the preset size, the machine door is opened. Then, the tail end of the fabric is manually cut with scissors for simple bundling. The complete fabric roll is then moved from the fabric winding machine to a trolley. A new paper tube (or plastic tube) is then loaded onto the metal winding roller of the fabric winding machine to continue winding the fabric. Finally, the open machine door is closed, and the circular knitting machine continues its production operation.

[0004] The inventors of this application have discovered that the current process of unloading fabric rolls using large circular knitting machines requires sufficient space during machine installation to ensure that the machine door can be fully opened to remove the fabric rolls; manual cutting and handling of the fabric rolls is required, which is labor-intensive and inefficient; and it cannot meet the needs of automated production. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic fabric roll feeding method for a circular knitting machine to solve the problems mentioned in the background art.

[0006] This invention provides an automatic fabric roll feeding method for a circular knitting machine, wherein the frame of the circular knitting machine is equipped with a sliding platform, and the method includes the following steps:

[0007] When the outer diameter of the S1 fabric roll reaches the preset size, the fabric roll will be automatically cut.

[0008] S2 automatically moves the cut fabric roll to the sliding platform;

[0009] S3 moves the sliding platform horizontally, allowing the fabric roll to pass horizontally through the pre-drilled hole in the machine door;

[0010] The S4 extraction unit receives the fabric rolls and transports them to the designated location.

[0011] Based on the above scheme, the automatic fabric roll feeding method of the circular knitting machine of the present invention automatically cuts the fabric when the outer diameter of the fabric roll reaches the preset size. Then, the cut fabric roll is automatically moved to a sliding platform, which then moves horizontally so that the fabric roll passes horizontally through the pre-drilled hole at the machine door. Finally, the extraction mechanism receives the fabric roll and transports it to a designated position. The automatic fabric roll feeding method of the circular knitting machine of the present invention automatically completes the fabric cutting, and the fabric roll is horizontally fed out from the pre-drilled hole at the machine door through the sliding platform. Then, it is received and transported to a designated position by the extraction mechanism. This method has the advantages of small machine footprint, high production efficiency, and automatic fabric roll feeding, enabling unmanned production and thus meeting the needs of automated production.

[0012] In one feasible solution, in step S1, when the outer diameter of the fabric roll reaches the preset size, the sensor is triggered to stop the machine, and then the fabric roll is automatically cut by the cutting knife.

[0013] In one feasible solution, in step S2, the fabric roll is automatically transferred to the sliding platform by a gripping and moving mechanism.

[0014] In one feasible approach, in step S3, the sliding platform moves along a linear guide rail, allowing the fabric roll to pass through the pre-drilled hole in the machine door.

[0015] In one feasible solution, in step S4, the extraction mechanism is an AGV (Automated Guided Vehicle). Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0029] As described in the background section of this application, the current fabric roll unloading process of a circular knitting machine is as follows: when the outer diameter of the fabric roll wound by the fabric rolling machine reaches the preset size, the machine door is opened, and then the tail of the fabric is manually cut with scissors for simple bundling. The complete fabric roll is then moved from the fabric rolling machine to a handcart, and a new paper tube (or plastic tube) is loaded onto the metal roller of the fabric rolling machine to continue winding the fabric. Finally, the opened machine door is closed, and the circular knitting machine continues its production operation.

[0030] The inventors of this application have discovered that the current process of unloading fabric rolls using large circular knitting machines requires sufficient space during machine installation to ensure that the machine door can be fully opened to remove the fabric rolls; manual cutting and handling of the fabric rolls is required, which is labor-intensive and inefficient; and it cannot meet the needs of automated production.

[0031] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0032] Figure 1 This is a schematic diagram of a circular knitting machine according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the first state of the fabric roll in an embodiment of the present invention. Figure 3 This is a schematic diagram of the second state of the fabric roll in an embodiment of the present invention. Figure 4 This is a schematic diagram of the fabric roll on the sliding platform in an embodiment of the present invention. Figure 5 This is a schematic diagram of the third state of the fabric roll in an embodiment of the present invention. Figure 6 This is a schematic diagram of the fourth state of the fabric roll in an embodiment of the present invention.

[0033] like Figures 1 to 6 As shown, the automatic fabric roll feeding method of the circular knitting machine in this embodiment includes the following steps:

[0034] When the outer diameter of the S1 fabric roll reaches the preset size, the fabric roll will be automatically cut.

[0035] S2 moves the cut fabric roll to the sliding platform;

[0036] The S3 sliding platform moves axially, allowing the fabric roll to pass through the pre-drilled hole in the machine door along the horizontal axis;

[0037] The S4 extraction mechanism grabs the fabric roll and transports it to the designated location.

[0038] In this embodiment, a frame is provided inside the door 11 of the large circular knitting machine 10, the fabric rolling machine 12 is mounted on the frame, a sliding platform 13 is provided on the frame, and a pre-made hole 111 is provided on the side wall of the door 11.

[0039] The fabric woven by the circular knitting machine is wound onto the winding roller of the fabric winding machine 12 to form a fabric roll 20. When the outer diameter of the fabric roll 20 reaches the preset size, the fabric is automatically cut by the automatic fabric cutting mechanism, and the fabric roll 20 is separated from the woven fabric. Then, the fabric roll 20 is automatically dropped onto the sliding platform 13, and the sliding platform 13 is automatically moved horizontally along the axial direction of the machine door 11, so that the fabric roll 20 passes horizontally through the pre-drilled hole 111 at the machine door 11. Finally, the extraction mechanism (such as an AGV intelligent vehicle) receives and transports the fabric roll 20 to the designated position.

[0040] As can be seen from the above, the automatic fabric roll feeding method of the circular knitting machine in this embodiment automatically cuts the fabric when the outer diameter of the fabric roll reaches the preset size. Then, the cut fabric roll is automatically moved to a sliding platform, which then moves horizontally so that the fabric roll passes horizontally through the pre-drilled hole at the machine door. Finally, the extraction mechanism receives the fabric roll and transports it to a designated position. This automatic fabric roll feeding method of the circular knitting machine of the present invention automatically completes the fabric cutting, and the fabric roll is horizontally fed out from the pre-drilled hole at the machine door via the sliding platform. Then, it is received and transported to a designated position by the extraction mechanism. It has the advantages of small machine footprint, high production efficiency, and automatic fabric roll feeding, enabling unmanned production and thus meeting the needs of automated production.

[0041] Optionally, in the automatic fabric roll feeding method of the circular knitting machine in this embodiment, in step S1, when the fabric roll reaches the preset size, a sensor (such as a micro switch) is triggered, and then an electric fabric cutter is used to automatically cut the fabric roll.

[0042] Specifically, a microswitch is installed on the frame inside the circular knitting machine door 11. This microswitch is electrically connected to the machine's controller. The fabric being woven by the circular knitting machine is wound onto the fabric roll. When the outer diameter of the fabric roll 20 reaches a preset size, the roll triggers the microswitch, which sends a signal to the controller. The controller then stops the circular knitting machine. Next, the controller controls the cutting blade to move in a straight line, automatically cutting the fabric and completely separating the fabric roll from the woven fabric. Figure 2 The state shown.

[0043] Optionally, in the automatic fabric roll feeding method of the circular knitting machine in this embodiment, in step S2, the fabric roll is transferred to the sliding platform by a gripping and moving mechanism.

[0044] Specifically, a gripping and moving mechanism and a sliding platform 13 are provided on the frame inside the machine door 11, and the gripping and moving mechanism is electrically connected to the controller.

[0045] After the fabric roll 20 is cut and separated from the fabric, the gripping and moving mechanism grips the fabric roll 20 on the fabric rolling machine and moves the fabric roll 20 onto the sliding platform 13, as follows: Figure 3 , Figure 4The state shown.

[0046] Optionally, in the automatic fabric roll feeding method of the circular knitting machine in this embodiment, in step S3, the sliding platform moves along the linear slide rail so that the fabric roll passes through the pre-made hole of the machine door.

[0047] Specifically, a linear guide rail is provided on the frame, and a sliding platform 13 is mounted on the linear guide rail of the frame. After the fabric roll 20 is placed on the sliding platform 13, the controller controls the sliding platform 13 to move horizontally along the linear guide rail of the frame, so that the fabric roll 20 passes horizontally through the pre-drilled hole 111 of the machine door 11, and moves the fabric roll 20 to the outside of the machine door 11. Figure 5 The state shown.

[0048] Optionally, in the automatic fabric roll feeding method of the circular knitting machine in this embodiment, the extraction mechanism in step S4 is an AGV trolley 30.

[0049] Specifically, the AGV trolley 30 is electrically connected to the controller, which controls the AGV trolley 30 to travel to a preset position outside the machine door 11. When the fabric roll 20 is delivered out of the machine door, the AGV trolley 30 receives the fabric roll 20 delivered by the sliding platform 13, unloads the fabric roll 20 onto the AGV trolley 30, and then the AGV trolley 30 transports the fabric roll 20 and places it in the designated position, such as... Figure 5 , Figure 6 The state shown.
