Description

Technical Field

[0001] The present invention relates to the technical field of post-processing of gloves during production, and in particular to a glove wrist stretching device and method, and a conveying system provided with the device. Background Art

[0002] In the manufacturing process of disposable gloves, it is necessary to detect defects in disposable gloves before packaging to avoid defective disposable gloves from being packaged. With the development of automation technology, industrial production lines are increasingly inclined to use automated equipment to improve production efficiency and product quality. Currently, most defect detection methods use visual intelligent defect detection.

[0003] When the wrist of the glove is semi-demolded from the mold (only the wrist and palm are demolded), the wrist of the glove will be in a drooping state on the glove mold. Due to the influence of material properties and the demolding process, the wrist of the glove in the drooping state may be folded or wrinkled. The gloves in the drooping state will be detected and identified by the visual inspection device for defective gloves so that the defective gloves can be removed. For example, in the patent with application number CN202320309823.7, after the gloves in the drooping state enter the photographing device, the two sides of the drooping gloves are photographed, and the photographed pictures are visually inspected and analyzed. If the wrist of the glove is folded or wrinkled, it will be mistaken for a defect, which will affect the results of the visual inspection and analysis, resulting in the inability to complete the defect detection normally. According to statistics, after the gloves are semi-demolded, the proportion of folding or wrinkling on the wrist of the gloves is about 60%. If no treatment is done, the misjudgment rate is high. If they are stretched manually, more manpower is consumed, which increases labor costs.

[0004] In order to allow gloves in a drooping state to be normally photographed, inspected and analyzed for defects, the folded or wrinkled wrists of the gloves need to be stretched out before the gloves enter the visual inspection camera. Therefore, developing a device that can automatically and efficiently stretch the wrists of the gloves has become a technical problem that needs to be solved urgently in the industry. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a glove wrist stretching device, method and a conveying system equipped with the device.

[0006] The technical solution adopted by the present application to solve its technical problems is: a glove wrist stretching device, including a supporting part, a stretching part is arranged on the supporting part, the stretching part includes two stretching parts close to each other, the gap between the two stretching parts forms a stretching channel, and the stretching parts are arranged obliquely.

[0007] The present application arranges the entire support part below the transportation line after the gloves are demoulded or below the glove conveying line where the glove wrists need to be stretched. After the gloves are demoulded, they pass through the support part into the stretching channel, move along the stretching channel based on the glove wrist transportation line, and then the glove wrist is pulled out from the stretching channel. When pulled out, the folded part of the glove wrist is stretched.

[0008] One end of the stretching channel is an inlet end, and the other end is an outlet end. The height of the stretching piece gradually decreases from the inlet end to the outlet end of the stretching channel and is arranged in an inclined shape.

[0009] The expansion member is a plate member or a rod member.

[0010] The support portion comprises a transverse support member and a longitudinal support member, wherein the transverse support member is connected between the stretching member and the longitudinal support member.

[0011] The inlet end of the stretching channel is arranged in a trumpet shape.

[0012] The shapes of the transverse supporting members and the longitudinal supporting members include but are not limited to rods or plates.

[0013] A glove wrist stretching method, comprising: providing two stretching pieces close to each other, the two stretching pieces being arranged opposite to each other, preferably being arranged symmetrically, the gap between the two stretching pieces forming a stretching channel, and the stretching pieces being arranged obliquely;

[0014] The glove wrist stretch method includes the following steps:

[0015] The wrist of the glove enters the stretching channel downward, and as the glove moves horizontally, the inclined stretching piece stretches the wrist of the glove downward until the wrist of the glove is fully stretched.

[0016] A conveying system provided with a glove wrist stretching device comprises a conveying line for conveying a hand mold, the conveying line moves the hand mold with the glove into a demoulding device for semi-demolding and then outputs the hand mold, the glove wrist stretching device is arranged below the conveying line, and the glove wrist stretching device is arranged at the output side of the demoulding device;

[0017] After the gloves are semi-demolded, the wrists of the gloves face downwards, the entrance end of the stretching channel is higher than the height of the wrist opening of the gloves, and the exit end of the stretching channel is lower than the height of the wrist opening of the gloves. The gloves with wrists facing downwards enter the stretching channel along the conveyor line for wrist stretching.

[0018] The width of the stretch channel is less than the width of the wrist when the glove is hanging naturally.

[0019] When the glove enters the stretch channel, the stretch channel is located between the wrist port of the glove and the finger portion of the glove.

[0020] Based on the situation of the gloves of the application object, the setting of the bell mouth at the entrance end of the glove wrist stretching device guides the glove 7 to ensure that the glove 7 can accurately enter the stretching channel. As a preferred solution, the opening angle is preferably set in the range of 30°-60°, otherwise it will cause the glove to fail to enter accurately if the angle is too small, and it may lead to poor guiding effect if the angle is too large.

[0021] As a further preferred solution, the width of the stretch channel ranges from 6 mm to 12 mm, ensuring that the gloves can be accurately pulled out of the stretch channel and stretched when pulled out. If it is less than the above range, the stretch channel is narrow and the gloves may not be pulled out. Since the gloves are flexible products, if the stretch channel exceeds the above range, the stretching effect of the gloves will be affected.

[0022] As a further preferred embodiment, the inclination angle of the stretching piece is 20°-45°. If it is lower than the above range, the inclination angle of the stretching piece is low, and the wrist of the glove may be directly moved out from the exit end of the stretching channel without being pulled out and stretched; if it exceeds the above range, the glove will be moved out of the stretching channel relatively quickly and the stretching effect cannot be guaranteed.

[0023] As a further preferred solution, the height difference between the inlet and outlet of the stretching channel is in the range of 90 mm-150 mm, thereby ensuring that the gloves naturally fall into the stretching channel for stretching, further ensuring the stretching effect.

[0024] As a further preferred solution, the distance between the highest point of the glove wrist stretching device and the lowest point of the hand mold is 10 mm to 30 mm. The length of the glove part separated from the hand mold after the glove is semi-demolded is not uniform, so when setting, the relative position between the glove wrist stretching device and the hand mold is set to ensure that the glove after semi-demolding can accurately enter the stretching channel to achieve the glove wrist stretching operation.

[0025] Compared with the prior art, the present application has the following beneficial effects: providing a glove wrist stretching device and method with a simple structure, convenient operation, and the ability to effectively stretch the glove wrist, and a conveying system equipped with the device. The device is particularly suitable for a glove production line, and can ensure that the glove wrist is well stretched without affecting the production speed. When performing subsequent defective glove identification, it will not cause misjudgment due to the folding or wrinkling of the glove wrist, and at the same time ensure the subsequent stacking effect and ensure neat stacking.

[0026] The glove wrist stretching device provided by the present invention can significantly improve the automation level of glove production, reduce manual intervention, and reduce production costs while maintaining a high product quality standard;

[0027] It can efficiently stretch the wrist of the glove without affecting the speed of the production line, greatly reducing the time required for traditional manual operations and improving the smoothness and efficiency of the entire production process;

[0028] It can ensure that the wrist of each glove is stretched evenly and accurately, avoiding the quality inconsistency problem caused by human factors, thus effectively improving the overall quality level of the product;

[0029] Reducing the demand for labor reduces the operating costs of enterprises. At the same time, due to the reduction of manual intervention, the safety hazards in the working environment are also reduced accordingly.

[0030] The structure is concise and clear, easy to install and debug, and easy to clean and maintain in daily use, which ensures the long-term stable operation of the equipment while reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Example 1

[0039] Reference Figures 1 to 3 The glove wrist stretching device comprises a supporting part, a stretching part is arranged on the supporting part, the stretching part comprises two stretching pieces 1 close to each other, a gap between the two stretching pieces 1 forms a stretching channel 2, and the stretching pieces 1 are arranged obliquely.

[0040] One end of the stretching channel 2 is an inlet end, and the other end is an outlet end. The height of the stretching member 1 gradually decreases from the inlet end to the outlet end of the stretching channel 2 and is arranged in an inclined shape.

[0041] Furthermore, the support portion includes a transverse support member 3 and a longitudinal support member 6, and the transverse support member 3 is connected between the stretching member 1 and the longitudinal support member 6. Figure 2 and Figure 3 The present application further provides a base 4, the support portion is fixedly connected to the base 4 through a connecting member, the connecting member includes a cross bar fixedly arranged above the base 4, a connecting rod is arranged at each end of the cross bar, and the two ends of the connecting rod are fixedly connected to one end of the longitudinal support member 6. The other end of each longitudinal support member 6 is integrally formed or welded with the corresponding stretching member 1 through a transverse support member 3, without specific limitation.

[0042] Reference Figure 2 and Figure 3 In the present application, two transverse support members 3 are arranged at the same end of the stretching member 1 and are arranged in a back-to-back manner. The purpose of the transverse support member 3 is to make the plane where the longitudinal support member 6 on the same side is located not belong to the same plane as the vertical plane where the stretching member 1 on the corresponding side is located, so as to ensure that the stretching effect of the glove 7 is not affected by the support part. The shapes of the transverse support member 3 and the longitudinal support member 6 include but are not limited to rod-shaped or plate-shaped. The two stretching members 1 can be made of plate materials such as steel plates, and their structure is as follows Figure 3 As shown; the two stretching members 1 can also be made of round steel and other rod materials, and its structure is as Figure 2 shown.

[0043] The entrance end of the stretching channel 2 is trumpet-shaped. This configuration ensures that the glove 7 can accurately enter the stretching channel 2, facilitating the subsequent wrist stretching operation of the glove 7. Figure 2 and Figure 3 In the present application, the transverse support member 3 at the inlet end of the stretching channel 2 is arranged outwardly in a trumpet shape, thereby achieving a trumpet-shaped arrangement of the inlet end of the stretching channel 2.

[0044] Based on the glove wrist stretching method of the glove wrist stretching device, two stretching pieces 1 close to each other are arranged, the two stretching pieces 1 are symmetrically arranged, the gap between the two stretching pieces 1 forms a stretching channel 2, and the stretching pieces 1 are arranged obliquely;

Figure 1 As shown, the device is placed below the glove conveyor line, the inlet end of the stretching channel 2 is higher than the bottom of the glove 7, and the outlet end of the stretching channel 2 is lower than the bottom of the glove 7. After the wrist of the glove 7 is partially demolded from the mold, the wrist will be in a drooping state on the hand mold 5. Based on the operation of the conveyor line, the glove 7 in this state is translated into the stretching channel 2. At this time, the wrist of the glove 7 is located below the stretching channel 2. As the glove conveyor line drives the glove 7 to translate, it is pulled out from the stretching channel 2 when passing the lower end of the stretching channel 2. During the pulling-out process, the folded wrist is stretched.

[0048] This application is not only applicable to the production of specific types of gloves such as rubber or latex gloves, but the design concept can also be extended to the production process of other similar items, such as the finishing of soft material products such as socks and sleeves, showing good versatility.
