Description

Technical Field

[0001] This invention relates to the field of glove manufacturing technology, and in particular to a method for finishing gloves using a glove finishing machine. Background Technology

[0002] Glove machines are specialized equipment used in the existing technology to automate the production of knitted gloves. Under the guidance of a preset program, they can efficiently and efficiently complete the automated production of knitted gloves. The finished knitted gloves slide out under their own gravity, and then each glove is sorted and packaged manually. The advantage is that the gloves are produced with high efficiency, but the disadvantages are that manual glove sorting is inefficient, labor-intensive, and has high labor costs. There are currently many patents related to glove machines, such as CN104018289B and CN306155907S.

[0003] A finishing machine is a specialized piece of equipment used in the existing technology to automate the finishing of knitted gloves. It can automatically finish the knitted gloves produced by glove machines under the guidance of a preset program, thereby replacing manual finishing, improving efficiency, and greatly reducing labor costs. There are currently many patents related to finishing machines, such as CN212268019U and CN305869505S.

[0004] To improve production efficiency and reduce production costs, current knitted glove manufacturers typically purchase glove-making machines and finishing machines simultaneously and use them together for glove production and finishing. Usually, a single worker can oversee 40-50 machines at the same time, which greatly improves production efficiency.

[0005] With the continuous development of glove manufacturing technology, a new type of product has emerged that combines a glove-making machine and a glove-making machine into one. This product not only enables the production and finishing of gloves but, more importantly, reduces the production costs for manufacturers. Chinese patent publications CN216040076U and CN114561739A fall into this category. However, after conducting market research, the inventors of this patent discovered several shortcomings in the actual use of this technology: First, gloves come in a wide variety of thicknesses, and the fingers of thin gloves often bend forward or backward in different directions. During the clamping process, the two clamping arms and plates in this technology are prone to causing the fingers to fold backward, ultimately affecting the quality of the gloves. Second, the clamping plates do not inspect the gloves after clamping them before starting production of the next glove. If a defective glove falls off, it will directly damage the structure of the glove-making machine, with serious consequences. Summary of the Invention

[0006] This invention proposes a method for arranging gloves using a glove arranging machine, which solves the problem that the finger area is prone to folding during glove arranging in the prior art.

[0007] The technical solution of the present invention is implemented as follows: a method for finishing gloves using a glove finishing machine, comprising the following sequential steps.

[0008] S1. The fixed gripper and the moving gripper are at the origin position. At this position, the fixed gripper and the moving gripper are opened to the maximum angle. The horizontal distance between the upper ends of the fixed gripper and the moving gripper is greater than the horizontal distance between the two optical axes in the glove machine.

[0009] S2. When the five fingers of the glove are finished, the fixed gripper and the movable gripper begin to rise and reach the first position, at which position the five fingers of the glove are located between the fixed gripper and the movable gripper;

[0010] S3. When the glove is knitted to the cuff, the moving jaw closes, so that the fixed jaw and the moving jaw clamp the five fingers of the glove and move down to the second position;

[0011] S4. The moving gripper opens again. At this time, the angle between the fixed gripper and the moving gripper is less than the maximum angle, and the horizontal distance between the upper ends of the fixed gripper and the moving gripper is less than the horizontal distance between the two optical axes in the glove machine.

[0012] S5. The fixed gripper and the movable gripper rise to the third position, which is the extreme position of the fixed gripper and the movable gripper. The upper ends of the fixed gripper and the movable gripper are higher than the optical axis.

[0013] S6. After the cuff of the glove is knitted, the moving jaw closes, allowing the fixed jaw and moving jaw to grip the finished glove and move it down to the original position.

[0014] In a preferred embodiment, the glove making machine includes a first control system for controlling glove production and a second control system for controlling the movements of the fixed gripper and the movable gripper.

[0015] In step S2, when the processing of the five fingers of the glove is completed, the first control system generates a roller positioning signal, and the second control system collects the signal and controls the fixed gripper and the moving gripper to move.

[0016] In step S3, when the glove is knitted to the cuff, the first control system sends an action signal to the elastic shears or hot melt shears, and the second control system collects the signal and controls the movement of the gripper.

[0017] In step S6, after the glove cuff is woven, the first control system sends an action signal to the elastic shears or hot melt shears again, and the second control system collects the signal and controls the movement of the gripper.

[0018] In a preferred embodiment, the glove forming machine is equipped with a drop failure sensing switch, which is used to sense the glove between the fixed gripper and the moving gripper in step S6. After step S6 is completed, the second control system controls the fixed gripper and the moving gripper to move closer to the drop failure sensing switch.

[0019] If the faulty sensor can detect the glove between the fixed and moving grippers, the first control system sends a command to continue producing the next glove.

[0020] If the faulty sensor fails to detect the glove between the stationary and moving grippers, the first control system will sound an alarm and stop glove production.

[0021] In a preferred embodiment, the glove forming machine is equipped with multiple sensors for sensing the progress of glove production. The sensors collect the corresponding signals in steps S2, S3 and S6 respectively, and control the fixed gripper and the moving gripper to move.

[0022] In a preferred embodiment, there is a gap between the rotation center of the moving gripper and the fixed gripper.

[0023] After adopting the above technical solution, the beneficial effects of the present invention are as follows: When finishing gloves during production, the method of the present invention fully considers the structural characteristics of the glove production section and the softness of the freshly produced gloves. First, the fixed and movable grippers are opened to their maximum angle to ensure that the gloves in production can fall into the space. After the five fingers of the glove are finished, the fixed and movable grippers can rise to a certain height. This height only requires that the two grippers can cover the five fingers, not the cuff of the glove. Therefore, this height is not limited by the two optical axes in the glove machine, while ensuring that all five fingers fall between the two grippers. Then, the movable gripper moves to clamp the five fingers of the glove. During this process, regardless of the degree of forward or backward bending of the fingers, the two grippers can ensure that they are flattened. After flattening, the two grippers move down a certain distance. The purpose of this action is to use the two grippers to smooth and straighten the five fingers of the glove, laying a good foundation for subsequent finishing. Therefore, the downward distance of the two grippers does not need to be large. As glove production continues, the moving grippers open again at a certain angle. This angle doesn't need to be too large, because the five fingers of the glove are already positioned between the two grippers and have been basically shaped after being straightened and smoothed. The purpose of opening the moving grippers is to facilitate their upward movement, reaching their highest limit. This position ensures that the upper ends of the two grippers reach the cuff of the glove, preventing drooping during output. Secondly, it avoids the positions of the two optical axes during the upward movement. Once the cuff of the glove is finished, the moving grippers close again, clamping the glove back to its original position.

[0024] The entire process of the present invention fully considers the existing structural characteristics of the glove production section and the softness of the freshly produced gloves. By using the basic actions of the grippers—"rise → clamp → smooth and straighten → open → rise again → clamp again → send out"—the phenomenon of reverse folding of the finger parts of the gloves is eliminated, ensuring the quality of glove finishing.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1 The diagram illustrates a conventional knitted glove, which can be divided into a finger section, a cuff section, and the area between the two. Existing glove machines produce this type of glove from the bottom up, first processing the five fingers and then the cuff. Once the elastic or heat-fused yarn in the cuff section is completed, elastic or heat-fused yarn is cut with elastic shears, and the entire glove is finished. The glove then slides out under its own weight. The above production process and structure are existing technology and will not be described in detail here.

[0032] like Figures 2 to 9The diagram shows the operation process of the present invention. Throughout the process, the glove 1 is continuously processed and slowly moves downward as its length increases. The left optical axis 5 and right optical axis 6 on both sides of the glove 1 are existing structures in the prior art (refer to components 13 and 14 in publication number CN111334924A).

[0033] Example 1:

[0034] like Figure 10 The diagram shown is a signal flow chart of the control system of the present invention, which employs two control systems, including a first control system and a second control system.

[0035] The first control system is used to control the glove production process, which is well known in the prior art, during the glove production process (i.e. Figures 2 to 9 During the process, the first control system generates several control signals according to the different production progresses. Among them, the three most critical signals include: first, when the five fingers of the glove are finished (corresponding to...). Figure 2 The first control system generates a roller positioning signal; the second is when the glove is processed to the cuff area (corresponding to...). Figure 3 The first control system sends an action signal to the elastic band scissors or hot melt scissors, causing them to loosen the unsew stitching; the third is when the cuff of the glove is finished (corresponding to...). Figure 7 The first control system then sends an action signal to the rubber band shears or hot melt shears again, causing the rubber band shears or hot melt shears to cut the rubber band or hot melt wire.

[0036] The second control system is used to control the glove finishing process. It mainly controls the movement of the fixed gripper 2 and the movable gripper 3 by collecting three signals generated by the first control system, thereby achieving the finishing of the gloves. The specific steps are described below.

[0037] like Figure 2 As shown, the newly produced gloves 1 are prone to bending forward or backward among their five fingers 11, and the bending directions are not always the same. To solve the specific problem raised in this patent, the method of this invention adopts the following basic sequence:

[0038] S1. Will Figure 2 The state of the fixed gripper 2 and the movable gripper 3 is defined as the origin state. At this time, the angle between the fixed gripper 2 and the movable gripper 3 is the maximum angle between the two. The width between their upper ends must be greater than the width between the left optical axis 5 and the right optical axis 6. For example, the width between the upper ends of the fixed gripper 2 and the movable gripper 3 can be set to 5cm to ensure that the glove 1 can be accommodated. The fixed gripper 2 must also be located inside the left optical axis 5 to ensure that the fixed gripper 2 and the movable gripper 3 can move between the left optical axis 5 and the right optical axis 6 in the future.

[0039] S2. When the processing of the five fingers of glove 1 is completed ( Figure 2 As shown), the first control system generates a roller positioning signal, the second control system acquires this signal, and controls the fixed gripper 2 and the movable gripper 3 to begin rising and reach the first position, at which position the five fingers of the glove 1 are located between the fixed gripper 2 and the movable gripper 3. Figure 3 (as shown);

[0040] S3. When glove 1 is processed to the cuff area ( Figure 3 As shown), the first control system sends an action signal to the rubber band shears or hot melt shears, causing them to release the wire. The second control system receives this signal and controls the moving gripper 3 to close. Figure 4 As shown), then the fixed gripper 2 and the movable gripper 3 clamp the five fingers of the glove 1 and move downwards to the second position (as shown). Figure 5 (As shown); The purpose of this action is to allow the fixed gripper 2 and the movable gripper 3 to grip the five fingers of the glove and straighten them downwards, laying a good foundation for subsequent sorting. Therefore, the downward distance of the fixed gripper 2 and the movable gripper 3 does not need to be large.

[0041] S4. The second control system controls the moving gripper 3 to open again. Figure 6 As shown), at this time, the angle between the fixed jaw 2 and the movable jaw 3 is less than [the angle shown in the image]. Figure 2 The maximum angle in the middle, and the horizontal distance between the upper ends of the fixed jaw 2 and the movable jaw 3 is less than the horizontal distance between the left optical axis 5 and the right optical axis 6, for example, it can be 3cm. In this case, not only is the fixed jaw 2 located inside the left optical axis 5, but the movable jaw 3 is also located inside the right optical axis 6.

[0042] S5. The second control system controls the stationary gripper 2 and the moving gripper 3 to rise to the third position. Figure 7 As shown), this position is the limit position of the fixed gripper 2 and the movable gripper 3. Since the horizontal distance between the upper ends of the fixed gripper 2 and the movable gripper 3 is less than the horizontal distance between the left optical axis 5 and the right optical axis 6, the upper ends of the fixed gripper 2 and the movable gripper 3 can rise above the left optical axis 5 and the right optical axis 6. In addition, the two grippers have already smoothed and straightened the finger part of the glove 1. Therefore, it can be ensured that the upper ends of the fixed gripper 2 and the movable gripper 3 reach the cuff of the glove 1.

[0043] S6. When the knitting of the cuff section of the glove is completed ( Figure 7 As shown), the first control system sends an action signal to the elastic band shears or hot melt shears again, causing the elastic band shears or hot melt shears to cut the elastic band thread or hot melt thread, and the glove production is completed. At this time, the second control system collects the signal and controls the moving jaw 3 to close, so that the fixed jaw 2 and the moving jaw 3 clamp the completed glove and move it down to the origin position. Figure 8 and Figure 9(As shown). Moreover, in this state, the fixed gripper 2 and the movable gripper 3 grip the cuff of the glove 1, so the glove will not droop during the subsequent output and finishing process.

[0044] After the above actions are completed, in order to ensure the continued production of the next glove, the present invention also sets a drop defect sensing switch on the glove forming machine, which is used to sense the glove 1 between the fixed gripper 2 and the moving gripper 3 in step S6. That is, after step S6 is completed, the second control system controls the fixed gripper 2 and the moving gripper 3 to move closer to the drop defect sensing switch. If the drop defect sensing switch can sense the glove between the fixed gripper 2 and the moving gripper 3, the first control system sends an instruction to continue producing the next glove; if the drop defect sensing switch does not sense the glove between the fixed gripper 2 and the moving gripper 3, the first control system alarms and stops producing the glove.

[0045] As for what follows Figure 9 For information on how to output and organize the gloves, please refer to existing technologies.

[0046] Furthermore, in order to ensure that the glove 1 can fall smoothly between the fixed gripper 2 and the movable gripper 3 during the above process, the present invention sets the rotation center 4 of the movable gripper 3 to a structure with a gap between it and the fixed gripper 2. For example, the gap can be selected as 1cm. The purpose of setting this gap is to reserve a channel between the fixed gripper 2 and the movable gripper 3, so that the finger part of the glove 1 can smoothly descend in the channel. It is suitable for gloves of various lengths, and after the fixed gripper 2 and the movable gripper 3 are combined, the glove 1 can be clamped better.

[0047] Example 2:

[0048] The difference between this embodiment and embodiment one is that this embodiment no longer directly collects the three key signals generated by the first control system. Instead, multiple sensors for sensing the progress of glove production are directly installed on the glove forming machine. These sensors can also sense the corresponding time nodes according to the different progress of glove production and send signals to the second control system, so that the second control system controls the fixed gripper 2 and the moving gripper 3 to produce corresponding actions.

[0049] The remaining structure of this embodiment is basically the same as that of Embodiment 1, and will not be described again here.

[0050] Overall, the entire process of this invention fully considers the existing structural characteristics of the glove production section and the softness of the freshly produced gloves. Through experiments with actual products, it has been verified that by using the fixed and moving grippers to open and close at two different angles, in conjunction with their up-and-down movement, the phenomenon of reverse folding of the glove finger area is completely eliminated, ensuring the quality of glove finishing and demonstrating excellent practicality.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
