Description

Technical Field

[0001] A conveying device for picking up and stacking gloves belongs to the field of glove packaging technology. Background Technology

[0002] During the glove packaging process, after the soft gloves are produced, they are usually removed by a pick-up roller. A conveyor belt is installed on the lower side of the pick-up roller. The pick-up roller and the conveyor belt work together to unfold the picked gloves on the conveyor belt. The conveyor belt transports the gloves to the output end and then stops, and then the subsequent stacking process is carried out.

[0003] Prior art 1: Chinese utility model patent with application number 202221426597.2, application date June 9, 2022, and patent name "a conveying device for picking up and stacking gloves" describes a technical solution in which gloves are conveyed by multiple conveyor belts arranged side by side.

[0004] The drawback of this solution is that, due to the manufacturing error of the belts, the error between the belts will cause the belts to fluctuate during operation when a set of transmission mechanisms drives the operation of a group of conveyor belts, and may even cause belt deviation or belt climbing. This will seriously affect the normal delivery of gloves and the photoelectric switch's detection of gloves.

[0005] To address the aforementioned problems of prior art 1, the applicant of this application filed a Chinese utility model patent on March 22, 2024, with application number 202420567515.9 and patent title "A Thin Product Conveying Device with Detection Grooves" (hereinafter referred to as prior art 2), which describes a technical solution. In prior art 2, a single, wider conveyor belt (hereinafter referred to as a wide conveyor belt) replaces the multiple parallel conveyor belts in prior art 1. The wide conveyor belt is driven by a roller motor. To prevent the wide conveyor belt from deviating, a positioning strip is provided on the inner ring of the wide conveyor belt, and a positioning groove is formed on the surface of the electric roller to engage with the positioning strip. Furthermore, to facilitate the detection of gloves on the surface of the wide conveyor belt, multiple detection grooves are formed on the outer ring of the wide conveyor belt, and a photoelectric switch is installed above each detection groove. The change in the appearance of gloves on the surface of the wide conveyor belt enables the detection of gloves.

[0006] However, the following problems were found in the actual implementation of the existing technology 2: 1. Heat dissipation problem. When the electric roller rotates, it generates a lot of heat inside the cylinder. In order to address the heat dissipation problem, the prior art 2 uses the method of opening heat dissipation holes on the surface of the cylinder and at the end caps at both ends of the cylinder. However, the actual heat dissipation effect is not good. The reasons are: (1) The heat dissipation method in this solution is passive heat dissipation; (2) A portion of the heat dissipation holes on the surface of the cylinder is always covered by the wide conveyor belt. This leads to the problem of poor heat dissipation effect.

[0007] 2. Cost issue. In the prior art 2, since a single conveyor belt is used, if the conveyor belt is damaged in any part, the entire conveyor belt needs to be replaced, which increases the cost.

[0008] 3. Regarding the issue of detection accuracy, in actual implementation, it was found that when inspecting gloves using the detection groove, due to the thinness of the gloves themselves and the depth of the detection groove, missed detections frequently occurred. However, the applicant of this application discovered that the solution using multiple conveyor belts in prior art 1, utilizing the gap between two conveyor belts, can actually solve the detection accuracy and cost issues caused by the detection groove in prior art 2.

[0009] However, it is difficult to directly combine the above-mentioned prior art 1 and prior art 2 to avoid their respective defects and obtain a better technical solution. The reason is that although the "anti-deviation" solution achieved by the positioning groove in prior art 2 can overcome the problems of prior art 1, the heat dissipation problem still exists. Furthermore, although the heat dissipation problem is not mentioned in the content of prior art 1, it is known to those skilled in the art that it also has a heat dissipation problem.

[0010] Furthermore, after simply combining existing technologies 1 and 2, in addition to the aforementioned reasons for poor heat dissipation, new problems arise: if the wide conveyor belt in existing technology 2 is replaced with multiple narrow conveyor belts in existing technology 1, it is necessary to set multiple positioning grooves on the surface of the electric drum corresponding to the number of conveyor belts, which also increases the processing difficulty of the drum. Moreover, the heat dissipation holes on the surface of the drum will inevitably overlap with the positions of the positioning grooves, which not only disrupts the integrity of the positioning grooves but also further increases the processing difficulty of the drum. Utility Model Content

[0011] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a conveying device for picking up and stacking gloves by setting fan blades inside the roller motor to realize active heat dissipation of the roller motor and eliminate the problem of poor heat dissipation effect under passive heat dissipation of the roller motor in the prior art.

[0012] The technical solution adopted by this utility model to solve its technical problem is as follows: the conveying device for picking and stacking gloves includes a support frame, an active roller and a driven roller are arranged in the support frame, and a conveyor belt is fitted outside the active roller and the driven roller. A detection sensor is arranged above the conveyor belt. The active roller includes a cylinder body, and a drive motor is arranged in the cylinder body. The cylinder body and the drive motor rotate relative to each other. The feature is that fan blades are arranged in the cylinder body. The fan blades include a first fan blade and a second fan blade located at both ends of the drive motor. The air outlet direction of the first fan blade and the second fan blade is the same.

[0013] Preferably, both the first and second blades include a fixing ring and a number of blades evenly arranged around the fixing ring.

[0014] Preferably, the conveyor belts include multiple belts arranged along the axial direction of the drive roller, with a detection gap formed between any two adjacent conveyor belts, and the detection sensor is located above the detection gap.

[0015] Preferably, only one detection sensor is installed above each detection gap, along the arrangement direction of the conveyor belt.

[0016] Preferably, a positioning strip is provided on the inner ring of the conveyor belt, and grooves corresponding to the positioning strips on the inner side of each conveyor belt are opened on the surfaces of the drive roller and the driven roller.

[0017] Preferably, end caps are fixed at both ends of the cylinder, and the first blade and the second blade are respectively installed on the inner end faces of the end caps.

[0018] Preferably, a support frame is provided, with the driving roller and the driven roller respectively installed at both ends of the support frame, and a tensioning mechanism for tensioning the conveyor belt is provided at at least one end of the support frame.

[0019] Preferably, a motor support shaft and a cylinder support shaft are respectively led out from the center of the two end caps. The motor support shaft and the cylinder support shaft are respectively fixed to the bracket and rotate relative to the cylinder at the same time.

[0020] Compared with the prior art, the beneficial effects of this utility model are: In the conveying device for picking up and stacking gloves in this application, active heat dissipation of the roller motor is achieved by setting fan blades inside the roller motor, which eliminates the problem of poor heat dissipation effect under passive heat dissipation of the roller motor in the prior art.

[0021] The conveyor belt consists of multiple belts arranged side by side, and the gap between two adjacent conveyor belts is used as the detection gap, which improves the detection accuracy of gloves.

[0022] The groove design prevents each conveyor belt from running off-track. Furthermore, the use of an actively cooled roller motor, combined with the arrangement of multiple conveyor belts and the anti-run-off structure, improves detection accuracy while ensuring effective heat dissipation.

[0023] The drive motor is a stepper motor, so the start and stop of the drive motor can be precisely controlled by pulse signals. Therefore, at any gap between two conveyor belts, along the running direction of the conveyor belt, only one detection sensor is set to achieve precise control of the glove's stop position. This avoids the drawback of the existing technology, which requires two sensors to be set in the middle of every two adjacent conveyor belts, and reduces costs. Attached Figure Description

[0033] Figures 1-8 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-8 The present invention will be further described below.

[0034] like Figures 1-2 As shown, a conveying device for picking and stacking gloves includes a support 6, which comprises two opposing vertical plates. A drive roller 3 is mounted at one end of each plate, and a driven roller 7 is mounted at the other end. A conveyor belt 1 is fitted around the drive roller 3 and the driven roller 7. The conveyor belt 1 comprises multiple belts spaced apart along the axial direction of the drive roller 3, with a gap between adjacent belts 1. Above the conveyor belts 1, a set of detection sensors 2 is mounted, with only one sensor 2 positioned at the top of each gap.

[0035] The working process is the same as in the prior art: when the drive roller 3 rotates, it drives the conveyor belt 1 to move in a cycle. After the glove is removed by the pick-up roller (not shown in the figure), it is transferred to the surface of the conveyor belt 1 for conveying. When the glove moves with the conveyor belt 1 to the detection sensor 2, the detection sensor 2 detects the glove and controls the drive roller 3 to stop rotating. The glove stops on the surface of the conveyor belt 1, and then the subsequent stacking process is carried out. The detection sensor 2 can be implemented in various ways in the art, such as photoelectric switches, distance sensors, etc.

[0036] A roller seat 4 is also provided between the two vertical plates of the support frame 6, and an idler roller 5 is installed on top of the roller seat 4. The idler roller 5 is located below the return conveyor belt 1 and supports the conveyor belt 1. Tensioning mechanisms are provided on both sides of the end of the support frame 6, and the drive roller 3 is installed in the tensioning mechanism to tension the conveyor belt 1. The tensioning mechanism can also be provided at the other end of the support frame 6.

[0037] like Figure 3 As shown, the tensioning mechanism includes a tensioning frame 12, which includes a vertical section fixed to the upright plate and a horizontal section that bends vertically from the top of the vertical section and is located above the upper edge of the upright plate. A tensioning groove 8 is provided in the middle of the horizontal section of the tensioning frame 12, and a guide rail 10 is provided on the upper edge of the upright plate. The guide rail 10 and the tensioning groove 8 in the tensioning frame 12 are arranged vertically opposite each other.

[0038] A rotating shaft seat 11 is slidably installed between the tension groove 8 and the guide rail 10. The bottom of the rotating shaft seat 11 is slidably set with the guide rail 10. The rotating shaft of the drive roller 3 is fixed in the rotating shaft seat 11. The locking bolt 9 passes through the tension groove 8 and is screwed into the top of the rotating shaft seat 11. After adjusting the tension of the conveyor belt 1, the rotating shaft seat 11 is locked by the locking bolt 9.

[0039] The drive roller 3 is a roller motor, such as Figures 4-6As shown, the drum motor includes a drum body 14, with end caps 15 installed at both ends of the drum body 14. Several convection holes 16 are formed on the surface of each end cap 15. A motor support shaft 17 and a drum support shaft 18 are coaxially extended from the center of each end cap 15 of the drum body 14. The motor support shaft 17 and the drum support shaft 18 are respectively inserted into and fixed within the rotating shaft seats 11 of the tensioning mechanisms on both sides of the end of the aforementioned bracket 6.

[0040] Multiple positioning grooves 13, corresponding one-to-one with the conveyor belts 1, are formed on the surface of the drum 14 of the roller motor. Corresponding grooves 13 are formed on the surface of the driven roller 7. A positioning strip protrudes from the center of the inner surface of the conveyor belt 1. After each conveyor belt 1 is fitted onto the surfaces of the driving roller 3 and the driven roller 7, the positioning strip on its inner wall engages with the positioning grooves 13 on the surface of the drum 14 and the corresponding grooves on the surface of the driven roller 7, preventing the conveyor belt 1 from deviating during long-term travel.

[0041] Combination Figure 7 A drive motor 20 is disposed at the center of the cylinder 14. A motor support shaft 17 is coaxially fixed at the center of the housing of the drive motor 20 and extends from the center of the corresponding side end cover 15. The motor support shaft 17 is a hollow shaft. The wires (control wires, power wires) of the drive motor 20 enter the interior of the motor support shaft 17 radially from the side and extend out along the axial direction of the motor support shaft 17. A cylinder support shaft 18 is rotatably disposed at the center of the other end cover 15 and extends from the center of the corresponding side end cover 15.

[0042] The motor shaft of the drive motor 20 extends from the center of the end face opposite to the motor support shaft 17, and a splined shaft 22 is coaxially fixed to the outside of the motor shaft of the drive motor 20. Bearing seats are respectively provided at the center of the inner side of the end caps 15 at both ends, and the motor support shaft 17 and the cylinder support shaft 18 pass through the bearings at their respective ends. The bearing seat inside the end cap 15 at the cylinder support shaft 18 is fitted onto the outer end of the splined shaft 22 and is coaxially fixed with the splined shaft 22. Therefore, when the drive motor 20 is working, under the support of the motor support shaft 17 and the cylinder support shaft 18, the motor shaft drives the corresponding end cap 15 to rotate via the splined shaft 22, further driving the cylinder 14 and the end cap 15 at the other end to rotate, thereby driving the conveyor belt 1.

[0043] A first fan blade 19 and a second fan blade 21 are respectively provided on the inner side of the end caps 15 at both ends. The first fan blade 19 and the second fan blade 21 have the same structure, such as... Figure 8 As shown, it includes a fixing ring 23 and several blades 24 evenly arranged around the fixing ring 23. The first blade 19 and the second blade 21 are fixed to the center of the inner side of the corresponding end cover 15 by their respective fixing rings 23.

[0044] When the end caps 15 rotate under the drive of the motor 20, the first blade 19 and the second blade 21 rotate synchronously. By setting the tilt direction of the blades 24 of the first blade 19 and the second blade 21, the air delivery direction of the first blade 19 and the second blade 21 is the same when they rotate synchronously. Therefore, when the first blade 19 and the second blade 21 rotate, the external air flows through the convection holes 16 at the end caps 15 along the axial direction of the cylinder 14, realizing active heat dissipation inside the drum motor.

[0045] The specific working process and working principle are as follows: When the drive motor 20 is working, it drives the end cap 15 fitted with it to rotate via the splined shaft 22, which in turn drives the cylinder 14 and the end cap 15 at the other end to rotate, thereby driving the conveyor belt 1. At this time, the conveyor belt 1 circulates between the driving roller 3 and the driven roller 7. The two end caps 15 rotate simultaneously under the drive of the drive motor 20. At this time, the first blade 19 and the second blade 21 rotate synchronously, so that the external air flows through the convection holes 16 at the two end caps 15 along the axial direction of the cylinder 14, thereby achieving active heat dissipation inside the roller motor.

[0046] After the gloves are removed by the pick-up roller (not shown in the figure), they are transferred to the surface of conveyor belt 1 for conveying. When the gloves move with conveyor belt 1 to the detection sensor 2, the detection sensor 2 detects the gloves and controls the drive roller 3 to stop rotating. The gloves stop on the surface of conveyor belt 1 and then proceed to the subsequent stacking process.

[0047] Furthermore, in the conveyor device for glove picking and stacking in this application, the drive motor 20 is implemented using a stepper motor. Therefore, the start and stop of the drive motor 20 can be precisely controlled by pulse signals. Thus, at any gap between two conveyor belts 1, along the running direction of the conveyor belt 1, only one detection sensor 2 is needed to achieve precise control of the glove's stopping position. This avoids the drawback of the prior art (such as the technical solution described in the Chinese utility model patent with application number 202221426597.2, application date June 9, 2022, and patent name "A conveyor device for glove picking and stacking"), which requires two sensors to be set in the middle of every two adjacent conveyor belts 1, thereby reducing costs.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
