Description

Technical Field

[0001] This invention relates to the field of glove manufacturing technology, specifically to a telescopic glove conveying device and conveying method. Background Technology

[0002] In the production of nitrile and PVC gloves, after the gloves are formed on the hand mold, the glove is in a state with the cup-shaped part facing upwards and the fingertips facing downwards. After being pre-demolded from the hand mold by the demolding machine, the glove is partially detached from the hand mold. At this time, the glove is hooked on the hand mold with the wrist facing downwards and the fingertips facing upwards. In the existing technology, the gloves after pre-demolding continue to enter the conveyor channel in this state and continue to enter the packaging process. As a result, the gloves to be packaged are stacked with the same orientation. After stacking, the gloves are not only easy to scatter, but the height of the wrist-to-fingertip side of the stacked gloves is also uneven, which affects the subsequent air venting effect. At the same time, in order to ensure a good packaging effect, it is often necessary to manually adjust the orientation of the gloves so that adjacent gloves are stacked crosswise, which is time-consuming and labor-intensive. Summary of the Invention

[0003] This invention discloses a telescopic glove conveying device and method, which solves the technical problems of existing technologies where manual adjustment of orientation is required during glove conveying and packaging, which is time-consuming, labor-intensive, and detrimental to packaging operations. It features a reasonable structure, multiple functions, and convenient cross-stacking of gloves. The technical solution adopted is as follows: A telescopic glove conveying device, comprising: frame; The feeding unit is located on the frame and can feed gloves that have been peeled off from the hand mold, so that the fingertips of the gloves fall onto the first conveyor belt first. The conveying unit includes a first conveyor belt mounted on a frame, a first drive unit, a moving roller, a first moving drive, a telescopic roller, and a second moving drive. The first conveyor belt is sleeved over the moving roller and the telescopic roller and can operate under the action of the first drive unit to transport gloves that have fallen onto the first conveyor belt forward. The moving roller can reciprocate under the action of the first moving drive, driving the end of the first conveyor belt to reciprocate horizontally so that the gloves are stacked crosswise. The telescopic roller is located away from the moving roller and can reciprocate under the action of the second moving drive to tension the first conveyor belt in real time. Based on the above technical solution, an exhaust unit is also included. The exhaust unit includes a second conveyor belt, which is designed to clamp and transport the glove downward with the first conveyor belt. When the glove enters the second exhaust channel formed between the first and second conveyor belts along the transport direction, the air inside the glove is discharged from the fingertips to the wrist.

[0004] Based on the above technical solution, the second conveyor belt is located near the end of the first conveyor belt's travel, and the second exhaust channel includes a horizontal length section and a vertical length section arranged sequentially along the conveying direction, so that the gloves fall vertically downwards to the next work station.

[0005] Based on the above technical solution, the exhaust unit further includes a third conveyor belt. The first conveyor belt is fitted with a plurality of first tension rollers, and the first conveyor belt includes an inclined length section. The third conveyor belt corresponds to the inclined length section and forms a third exhaust channel for the glove to pass through. The axial length of the third conveyor belt covers the inclined length section of the first conveyor belt and extends horizontally to both ends. The third conveyor belt and the first conveyor belt can clamp the glove so that it passes through the third exhaust channel.

[0006] Based on the above technical solution, the third conveyor belt operates actively or passively.

[0007] Based on the above technical solution, it also includes a first mounting base and a second mounting base. There are multiple movable rollers and they are disposed on the first mounting base. The first drive unit is fixed on the first mounting base. The first mounting base is horizontally slidably connected to the frame and can slide back and forth under the action of the first moving drive to drive the end of the first conveyor belt to slide back and forth horizontally so that the gloves are stacked crosswise. There are multiple telescopic rollers and they are disposed on the second mounting base. The second mounting base is horizontally slidably connected to the frame and can slide back and forth under the action of the second moving drive to tension the first conveyor belt in real time.

[0008] Based on the above technical solution, the feeding unit includes a rejection roller group, a rejection drive, a reversing component, and a reversing drive. The rejection roller group is located above the reversing component and includes two rejection rollers arranged opposite each other. The rejection drive is fixed on the frame and is used to drive the two rejection rollers to rotate in opposite directions. The roller surface of the rejection roller includes a concave portion. When the roller surfaces of the two rejection rollers are close together, they can clamp the glove and remove it from the hand. When the concave portions of the two rejection rollers are close together, they form a channel for the glove to fall, which can convey the glove downward to the reversing component. The reversing assembly includes several grippers arranged circumferentially, which can grip the wrist opening of the glove. The reversing drive can drive the reversing assembly to rotate so that the glove drops downward with the fingertips facing down.

[0009] Based on the above technical solution, the gripper includes a gripper drive and two gripping arms. The two gripping arms are arranged opposite to each other and can be opened and closed under the action of the gripper drive to grip or release the wrist opening of the glove. The gripping arms are provided with a number of air holes.

[0010] A glove conveying method, employing the telescopic glove conveying device described above, includes the following steps: Under the action of the feeding unit, the fingertips of the gloves first fall onto the first conveyor belt; The first drive unit drives the first conveyor belt to operate and transports the gloves forward; When the first pair of gloves is transported to the end of the first conveyor belt travel, the first moving drive drives the moving roller to slide horizontally along the first direction, causing the end of the first conveyor belt travel to slide horizontally along the first direction, so that the gloves fall to the next station in the state of wrist opening to fingertips. At the same time, the second moving drive drives the telescopic roller to slide horizontally along the second direction to tension the first conveyor belt. When the second pair of gloves is transported to the end of the first conveyor belt travel, the first moving drive drives the moving roller to slide horizontally in the second direction, causing the end of the first conveyor belt travel to slide horizontally in the second direction, so that the gloves fall to the next station in the state of fingertips-wrist opening, thus realizing the cross-stacking of gloves. At the same time, the second moving drive drives the telescopic roller to slide horizontally in the first direction to tension the first conveyor belt.

[0011] Based on the above technical solution, the telescopic glove conveying device further includes an exhaust unit, which includes a second conveyor belt and a third conveyor belt. The second conveyor belt is located near the end of the first conveyor belt's travel. The second conveyor belt is designed such that it can clamp and transport the glove forward with the first conveyor belt, and when the glove enters the second exhaust channel formed between the first and second conveyor belts along the transport direction, air inside the glove is discharged from the fingertips to the wrist. The third conveyor belt is inclined and can clamp and transport the glove forward with the first conveyor belt. When the glove enters the third exhaust channel formed between the first and third conveyor belts along the transport direction, air inside the glove is discharged from the fingertips to the wrist. Beneficial effects

[0012] This invention features a simple and ingenious structure. The movable roller and telescopic roller ensure that the end of the first conveyor belt remains taut while it moves horizontally. When the first conveyor belt moves in the first direction, the gloves are positioned with the wrist and fingertips facing each other; conversely, they are positioned in the opposite direction, thus achieving cross-stacking of the gloves. Furthermore, this invention completes the cross-stacking of gloves while they are being transported forward, facilitating stacking and packaging operations, effectively simplifying equipment, reducing labor costs, and minimizing space occupation.

[0013] In this invention, the exhaust unit includes a second conveyor belt and a third conveyor belt. The second and third conveyor belts, together with the first conveyor belt, form a second exhaust channel and a third exhaust channel, respectively, for step-by-step exhaust, which is beneficial for thorough exhaust. When the glove passes through the exhaust channel, the top and bottom surfaces of the glove are flexibly compressed by the conveyor belt. On the one hand, this allows internal air to be discharged from the fingertips to the wrist. The structure is simple and low-cost. Compared with the existing technology of stacking dozens of gloves in the same direction and then uniformly exhausting them, the manual labor intensity is low, the exhaust is more thorough, and it is convenient for subsequent stacking and packaging. On the other hand, it has good adaptability and can compress and exhaust gloves of different thicknesses and sizes. In addition, while forming the exhaust channel, the second and third conveyor belts can also clamp the glove forward with the first conveyor belt, thus forming a curved conveyor line. This allows the glove to move forward on the curved or inclined conveyor belt, achieving a compact arrangement of the conveyor line, which is beneficial for making full use of longitudinal space and reducing the occupation of horizontal space. In addition, the second exhaust channel is located near the end of the first conveyor belt and includes a horizontal length section and a vertical length section. On the one hand, it can promote more thorough exhaust, and on the other hand, it can facilitate the transfer of gloves to the next work station. The second exhaust channel is inclined, so that the gloves can complete the uphill or downhill movement during the exhaust process, improving the flexibility of the conveyor line layout.

[0014] The feeding unit in this invention is ingeniously designed. The reversing component allows the fingertips of the demolded gloves to fall onto the conveyor belt first, thus providing conditions for removing residual gas inside the gloves. As the conveyor belt clamps and transports the gloves forward, the gas inside the gloves can be squeezed out. This allows the venting action to be completed during the glove transport process. The ingenious structural design helps to save labor costs and improve packaging quality. Attached Figure Description

[0022] like Figures 1-7 The telescopic glove conveying device shown includes a frame 100, on which a feeding unit 1, a conveying unit 2 and an exhaust unit 3 are provided.

[0023] like Figures 1-5 As shown, the feeding unit 1 can peel gloves from the hand mold, allowing the fingertips of the gloves to fall onto the first conveyor belt 22 first; specifically, the feeding unit 1 includes a rejection roller group, a rejection drive 14, a reversing assembly 13, and a reversing drive 12. The frame 100 at the feeding unit 1 includes two side plates 111, which are connected by several support rods 112. The rejection roller group and the reversing assembly 13 are located between the two side plates 111, and the support rods 112 are distributed on both sides of the rejection roller group and the reversing assembly 13, as shown. Figure 2 As shown, the two side plates 111 are fixedly connected to the base downwards. The base is provided with several mounting holes, which facilitates the assembly and disassembly of the feeding unit 1 to other plates on the frame 100, making maintenance convenient.

[0024] The rejection roller group, reversing assembly 13, and first conveyor belt 22 are arranged sequentially from top to bottom, as follows: Figure 2 and 3 As shown, the reversing assembly 13 includes a plurality of circumferentially evenly arranged grippers 133, which are fixed on a disc base 132. The disc base 132 is rotatably connected to the two side plates 111 via a first shaft, and bearings are sleeved at the rotatable connection points. Each gripper 133 includes a gripper drive 1331 and two gripping arms 1332. The gripper drive 1331 is a finger cylinder fixed on the disc base 132. The two gripping arms 1332 are arranged opposite to each other and can be opened and closed under the action of the gripper drive 1331 to grip or release the glove wrist opening.

[0025] like Figure 4 As shown, the clamping arm 1332 includes a clamping part that can span the wrist opening of a glove. In other embodiments of the present invention, the clamping part can also span the wrist opening of multiple gloves, allowing for the simultaneous clamping of multiple gloves. The clamping arm 1332 near the clamping part is provided with several air vents 1333, which reduces static electricity and airflow disturbance caused by the opening and closing of the clamping arm 1332, enabling the grippers 133 to quickly and accurately clamp the gloves, ensuring a stable and continuous production process. Furthermore, the clamping arm 1332 is made of ABS plastic and is integrally molded, resulting in high structural strength and preventing wear on the gloves.

[0026] The reversing drive 12 includes a reversing motor, which is fixed on the side plate 111 and can transmit rotational motion to the first shaft. When the reversing drive 12 drives the first shaft to rotate, a gripper 133 rotates to a set position and can grip the wrist opening of the glove. When the gripper 133 continues to rotate, the fingertips of the glove fall onto the conveyor belt first, thus completing the glove reversing operation and providing conditions for removing residual gas inside the glove in the subsequent conveying process.

[0027] like Figure 2 As shown, it also includes a first optocoupler 134 and a first detection chip 135. The first optocoupler 134 is fixed on the disk base 132 of the commutation assembly 13 and electrically connected to an external controller. The first detection chip 135 is fixedly arranged to be recognized by the first optocoupler 134.

[0028] In addition, it also includes a protective cover 131 that covers the outside of the disc base 132 and rotates synchronously with the disc base 132. The protective cover 131 has a slot for accommodating the gripper 133. The protective cover 131 can prevent the reversing component from malfunctioning due to the gloves accidentally dropping material.

[0029] In the production process of nitrile and PVC gloves, after the gloves are formed on the hand mold, the glove is in a position with the cup-shaped opening facing upwards and the fingertips facing downwards. After being pre-demolded from the hand mold by the demolding machine, the glove is partially detached from the hand mold. At this point, the glove is hooked onto the hand mold with the wrist opening facing downwards and the fingertips facing upwards. The rejection roller group is located above the reversing assembly 13 and includes two rejection rollers 15 arranged opposite each other. The rejection drive 14 includes a rejection motor, which is fixed on the side plate 111 by a motor mount. The rejection motor can transmit the rotational motion to the roller shafts of the two rejection rollers 15 through a gearbox assembly, so that the two rejection rollers 15 rotate synchronously towards each other.

[0030] like Figure 1 and 2 As shown, the roller surface of the rejection roller 15 includes a recess 151. When the roller surfaces of the two rejection rollers 15 approach each other, the distance between the two rejection rollers 15 gradually decreases and then gradually increases, so as to clamp the glove and completely remove the glove from the hand. When the two rejection rollers 15 continue to rotate, their recesses 151 approach each other to form a channel for the glove to fall, so as to convey the glove downwards and make the gripper in the reversing assembly 13 stably clamp the wrist of the glove.

[0031] The area on the surface of the rejection roller 15 used for holding the glove is bonded with an abrasion-resistant fiber layer 152. The abrasion-resistant fiber layer 152 can come into contact with the glove to flexibly hold the glove, avoiding damage to the glove, and at the same time preventing the glove from adhering to the rejection roller 15 due to static electricity. In addition, the abrasion-resistant fiber layer 152 is provided with several elongated holes 1521, which can increase the friction between the abrasion-resistant fiber layer 152 and the glove, and firmly hold the glove.

[0032] like Figure 6 As shown, the conveying unit 2 includes a first conveyor belt, a first drive unit, a moving roller 23, a first moving drive 28, a telescopic roller 24, and a second moving drive 29, all mounted on the frame 100.

[0033] The first conveyor belt 22 is fitted around the moving roller 23 and the telescopic roller 24 and can operate under the action of the first drive unit to transport the gloves that have fallen onto the first conveyor belt 22 forward; such as Figure 6 As shown, a plurality of first tension rollers 25 are also fitted inside the first conveyor belt 22 to flexibly arrange the direction of the first conveyor belt 22.

[0034] The movable roller 23 is positioned near the end of the conveying section of the first conveyor belt 22 and can slide back and forth under the action of the first movable drive 28, so that the end of the first conveyor belt 22 moves back and forth horizontally. Specifically, it also includes a first mounting base 26, on which the movable roller 23 is mounted. The first mounting base 26 is horizontally and slidably connected to the frame 100 and can slide back and forth under the action of the first movable drive 28. In this embodiment, the first movable drive 28 includes a first movable motor, which is fixed to the frame 100 through a motor mount. The first movable motor drives the first mounting base 26 and the movable roller 23 on it to slide back and forth horizontally through a lead screw pair. When the first mounting base 26 moves in the first direction, the glove is placed in the wrist-fingertip position, and vice versa, thus completing the cross-stacking of the gloves.

[0035] It also includes a second sensor located near the end of the first conveyor belt 22. The second sensor is used to identify gloves and send a signal to an external controller to complete the counting of gloves.

[0036] The first drive unit includes a first motor fixed on the first mounting base 26. The first motor can transmit rotational motion to one of the moving rollers 23, thereby ensuring that the first conveyor belt 22 at the moving roller 23 has a relatively constant linear speed, so that the gloves fall steadily downwards.

[0037] To ensure the first conveyor belt 22 remains taut and stably transports the gloves forward, the telescopic roller 24 can reciprocate under the action of the second moving drive 29 to keep the first conveyor belt 22 taut in real time. Specifically, a second mounting base 27 is included, on which the telescopic roller 24 is mounted. The second mounting base 27 is horizontally and slidably connected to the frame 100 and can reciprocate under the action of the second moving drive 29. In this embodiment, the second moving drive 29 includes a second moving motor, which is fixed to the frame 100 via a motor mount. The second moving motor drives the second mounting base 27 and the telescopic roller 24 to reciprocate horizontally via a lead screw pair, ensuring the first conveyor belt 22 remains taut. The telescopic roller 24 is positioned away from the moving roller 23 to reduce the impact of its sliding on the linear speed of the first conveyor belt 22 at the moving roller 23.

[0038] like Figure 7 As shown, multiple moving rollers 23 together form a moving roller group, and the multiple moving rollers make the end of the first conveyor belt 22 include a horizontal conveying section and a vertical conveying section arranged sequentially along the conveying direction. This allows the gloves to be vertically disengaged from the first conveyor belt 22, thereby facilitating the cross-stacking of the gloves at the next work station.

[0039] In addition, a second conveyor belt 31 is included, with multiple second conveyor rollers 32 mounted on a first mounting base 26. The first mounting base 26 has two rollers, each connected to both ends of the roller shaft of the moving roller 23 and the second conveyor roller 32. A first motor transmits rotational motion to one of the second conveyor rollers 32 via a gear transmission mechanism. This allows the ends of the second conveyor belt 31 and the first conveyor belt 22 to move horizontally synchronously. The multiple second conveyor rollers 32 allow for flexible arrangement of the second conveyor belt 31, fitting snugly against the ends of the first conveyor belt 22. The ends of the second conveyor belt 31 and the first conveyor belt 22 together form an inverted L-shaped second exhaust channel. This second exhaust channel includes horizontal and vertical sections arranged sequentially along the conveying direction. It can clamp and transport the gloves downwards, allowing them to fall smoothly to the next workstation. During this process, the second conveyor belt 31 and the first conveyor belt 22 compress the gloves to expel air from inside.

[0040] In this embodiment, there are two telescopic rollers 24 arranged vertically, forming a telescopic roller group. There are two second mounting plates 7, each connected to one end of the roller shaft of one of the telescopic rollers 24. Figure 6 As shown, the telescopic roller group is positioned away from the end of the first conveyor belt 22 to reduce the impact of the displacement of the telescopic roller group 24 on the linear velocity of the end of the first conveyor belt 22.

[0041] It also includes a third conveyor belt 33, such as Figure 6As shown, the first conveyor belt 22 includes an inclined conveying section, which is located between the telescopic roller group and the moving roller group. The third conveyor belt 33 corresponds to the position of the inclined conveying section, so as to form a third exhaust channel together with the first conveyor belt 22, clamping and conveying the gloves forward. In addition, the length of the third conveyor belt 33 covers the length of the inclined conveying section and continues to extend horizontally to both ends of the inclined length section. This allows the gloves to enter the third exhaust channel formed by the third conveyor belt 33 and the first conveyor belt 22 more smoothly, while ensuring that the gloves can smoothly exit the third exhaust channel.

[0042] In this embodiment, given the periodic change in the linear velocity of the inclined conveying section, the third conveyor belt 33 is passively rotated synchronously with the first conveyor belt 22 under the friction of the gloves, so as to simplify the structure and reduce costs. In other embodiments of the present invention, a third drive unit is also provided. The third drive unit is fixed on the frame and can drive the third conveyor belt 33 to operate synchronously with the first conveyor belt 22 so as to properly clamp and transport the gloves forward.

[0043] like Figure 3 As shown, the third conveyor belt 33 is fitted with multiple third tension rollers 34. One end of the roller shafts of the first tension roller 25 and the third tension roller 34 is fixed on the frame 100 to form a cantilever structure, so as to facilitate the maintenance of the first conveyor belt 22 and the third conveyor belt 33.

[0044] Furthermore, the inner surface of the first conveyor belt 22 that contacts the moving roller 23, the telescopic roller 24 and the first tension roller 25 includes an axially extending first protrusion, and the corresponding positions of the moving roller 23, the telescopic roller 24 and the first tension roller 25 are provided with a first groove to accommodate the first protrusion, so as to position the first conveyor belt 22; the inner surface of the third conveyor belt 33 that contacts the third tension roller 34 includes an axially extending third protrusion, and the corresponding position of the third tension roller 34 is provided with a third groove to accommodate the third protrusion, so as to position the third conveyor belt 33.

[0045] A glove conveying method, employing the above-mentioned telescopic glove conveying device, includes the following steps: Under the action of the feeding unit 1, the fingertips of the gloves first fall onto the first conveyor belt 22. Specifically, when the roller surfaces of the two rejection rollers 15 approach each other, the distance between the two rejection rollers 15 gradually decreases to clamp the wrist opening of the gloves. As the rejection rollers 15 continue to rotate, the gloves are completely removed from the hand mold. As the rejection rollers 15 continue to rotate, the concave parts of the two rejection rollers 15 approach each other to form a channel for the gloves to fall, so as to convey the gloves downward. Simultaneously, the reversing drive 12 drives the gripper in the reversing assembly 13 to rotate, and the gripper drive 1331 drives the two gripping arms 1332 to open. After the glove's wrist opening enters between the two gripping arms 1332, the gripper drive 1331 drives the two gripping arms 1332 to close, so as to stably grip the glove's wrist opening. Then, the gripper 133 continues to rotate, and the fingertips of the glove are in a free state. Under the action of centrifugal force, the material first falls onto the first conveyor belt 22. When the gripper 133 continues to rotate and approaches the first conveyor belt 22, the gripper drive 1331 drives the two gripping arms 1332 to open, releasing the glove's wrist opening. At this time, the glove with the fingertips facing forward is transported forward by the first conveyor belt 22.

[0046] The first drive unit drives the first conveyor belt 22 to rotate and transport the gloves forward. The gloves first pass through the third exhaust channel. When the gloves enter the third exhaust channel, the gas inside the gloves is discharged from the fingertips to the wrist. At the same time, the third conveyor belt 33 and the first conveyor belt 22 clamp the gloves, allowing the gloves to climb up the first conveyor belt 22. Then the gloves pass through the second exhaust channel. When the gloves enter the second exhaust channel, the gas inside the gloves is discharged from the fingertips to the wrist. When the gloves pass through the second exhaust channel, they change their forward direction from horizontal to vertical, allowing the gloves to fall vertically downwards. At the same time, the clamping action of the second conveyor belt 31 and the first conveyor belt 22 makes the downward fall of the gloves more stable, which is beneficial to improving the cross-stacking effect of gloves. In addition, the setting of multiple exhaust channels allows the air inside the gloves to be discharged step by step, which is conducive to more thorough air removal.

[0047] When the first pair of gloves is transported to the end of the first conveyor belt 22, the first moving drive 28 drives the moving roller to slide horizontally in the first direction, causing the end of the first conveyor belt 22 to slide horizontally in the first direction, so that the glove is dropped to the next station in the state of wrist-fingertip. At the same time, the second moving drive 29 drives the telescopic roller 24 to slide horizontally in the second direction to tension the first conveyor belt 22. When the second pair of gloves is transported to the end of the first conveyor belt 22, the first moving drive 28 drives the moving roller 23 to slide horizontally in the second direction, causing the end of the first conveyor belt 22 to slide horizontally in the second direction, so that the gloves fall to the next station in the state of fingertips-wrist opening, thus realizing the cross-stacking of gloves. At the same time, the second moving drive 29 drives the telescopic roller 24 to slide horizontally in the first direction to tension the first conveyor belt 22.

[0048] This cycle repeats itself.

[0049] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
