Description

Technical Field

[0001] The invention discloses a positioning mechanism for adjusting the posture of gloves, belonging to the technical field of packaging equipment. Background Art

[0002] After the preparation of disposable gloves is completed, they need to go through post-processing steps (such as vulcanization, etc.). The gloves after the post-processing steps are in a scattered state and need to be sorted. Currently, this is mainly done manually, which is inefficient and cannot meet the production needs of gloves.

[0003] Practitioners hope to achieve posture adjustment of gloves through mechanical structures so that they can be flattened. When performing posture adjustment, the gloves are usually clamped by a robot and sent into a posture adjustment device. However, in actual operation, it is found that due to the soft texture of the gloves, the position of the gloves is inaccurate when entering the posture adjustment mechanical structure, and the posture adjustment effect is not ideal. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a positioning mechanism for adjusting the posture of gloves, so that the gloves can accurately enter the predetermined position and improve the success rate of posture adjustment.

[0005] The utility model solves the technical problem by adopting the following technical solution: the positioning mechanism for adjusting the posture of the gloves comprises a glove transmission mechanism and a pulling mechanism, the glove transmission mechanism has a transmission channel for placing the gloves, and the pulling mechanism is arranged on one side of the transmission channel.

[0006] Preferably, at least two groups of pulling mechanisms are arranged along the transmission direction of the transmission channel.

[0007] Preferably, the pulling mechanism comprises a pulling cam and a pulling power assembly driving the pulling cam to rotate, and the two pulling cams are arranged to rotate relative to each other.

[0008] Preferably, the pulling mechanism comprises at least two relatively rotating pulling brushes, and the two pulling brushes are respectively arranged on both sides of the glove in the transmission channel.

[0009] Preferably, the pulling mechanism comprises at least two rollers which rotate relative to each other, and the two rollers are respectively arranged on both sides of the glove in the transmission channel.

[0010] Preferably, the pulling mechanism comprises a pulling brush and a back plate, the pulling brush and the back plate are respectively arranged on both sides of the glove, and the pulling brush and the back plate cooperate to pull the glove to a predetermined position.

[0011] Preferably, the pulling mechanism is arranged on the lower side of the glove transmission mechanism.

[0012] Preferably, a guide plate is further provided on the upper side of the glove transmission mechanism, and two guide plates are respectively arranged on both sides of the transmission channel, and the distance between the two guide plates gradually decreases in the direction approaching the posture adjustment channel.

[0013] Preferably, the inlet of the glove transmission mechanism is in a bell-mouth shape.

[0014] Preferably, the glove transmission mechanism comprises two transmission belts, and a transmission channel is formed between the two transmission belts.

[0015] Preferably, the two transmission belts are connected to motors respectively. The two transmission belts can work independently, and a differential speed can be formed between the two transmission belts. The differential speed is used to drive the gloves in the transmission channel to rotate while the gloves are being transmitted, so as to pre-adjust the posture.

[0016] Compared with the prior art, the above technical solution of the positioning mechanism for adjusting the posture of the gloves has the following beneficial effects: the utility model sets a pulling mechanism on one side of the transmission channel to pull the gloves in the transmission channel. Since the gloves themselves have curling edges at the wrist part, the gloves will automatically be stuck on the glove transmission mechanism by the curling edges to achieve the positioning of the gloves, thereby ensuring that the position of the gloves entering the posture adjustment device is accurate and uniform, and improving the success rate of posture adjustment.

DETAILED DESCRIPTION

[0026] The following is combined with Figures 1 to 8 The utility model is further described.

[0027] Example 1

[0028] Reference Figure 1-3 , the positioning mechanism for adjusting the posture of the glove, the glove transmission mechanism and the pulling mechanism, the glove transmission mechanism has a transmission channel 6 for placing the glove, and the pulling mechanism is arranged on one side of the transmission channel 6. A glove 100 is placed in the transmission channel 6 by a human or a robot, and the pulling mechanism pulls the glove 100 to move it in a direction away from the glove 100 transmission mechanism. Since the wrist of the glove 100 has a curling edge 101, and the thickness of the two curling edges 101 on both sides of the wrist is greater than the width of the transmission channel 6, the curling edge 101 of the glove 100 will be stuck on one side of the transmission channel 6, and the other parts of the glove 100 are pulled to the other side of the transmission channel 6 by the pulling mechanism, so that the glove 100 is positioned based on the transmission channel 6.

[0029] The utility model utilizes a pulling mechanism to pull the glove 100 in the transmission channel 6 downward to complete the positioning of the glove 100, and at the same time can prevent a part of the glove 100 from hanging down to the outside of the transmission channel 6. Once the two parts of the glove 100 overlap each other, the glove 100 cannot be rotated in a predetermined direction subsequently, and it is difficult to adjust the posture.

[0030] In this embodiment, the glove transmission mechanism includes a first transmission belt 2 and a second transmission belt 3, which are arranged on a frame 1, and a transmission channel 6 is formed between the first transmission belt 2 and the second transmission belt 3. The first transmission belt 2 is connected to a first transmission motor 4 that drives it to run, and the second transmission belt 3 is connected to a second transmission motor 5 that drives it to run. The first transmission motor 4 and the second transmission motor 5 work independently, and can drive the first transmission belt 2 and the second transmission belt 3 to work synchronously, so as to transport the gloves 100 to the posture adjustment station.

[0031] The first transmission motor 4 and the second transmission motor 5 can also drive the first transmission belt 2 and the second transmission belt 3 to run at a differential speed, so as to utilize the speed difference between the first transmission belt 2 and the second transmission belt 3 to rotate the glove 100 in the transmission channel 6, and the glove 100 will gradually flatten during the rotation process instead of rotating as a whole. At this time, the first transmission belt 2 and the second transmission belt 3 can adjust the posture of the glove 100 while transmitting the glove 100. The differential operation of the first transmission belt 2 and the second transmission belt 3 is divided into the following two situations.

[0032] A. The first transmission belt 2 and the second transmission belt 3 complete the posture adjustment of the glove 100 while transmitting the glove 100. Since the differential operation is usually stopped after the posture adjustment is completed, the first transmission belt 2 and the second transmission belt 3 are changed from differential operation to synchronous operation, so the next glove 100 can only be fed in after the posture adjustment of one glove 100 is completed and finally sent out. The posture detection is usually completed by taking pictures with a camera.

[0033] B. Although the first transmission belt 2 and the second transmission belt 3 run at a differential speed, they are only used for pre-adjustment of posture, and the glove 100 still needs to be conveyed to the other two transmission belts or other posture adjustment structures for final posture adjustment. Therefore, it is usually not necessary to detect the posture of the glove 100 at the first transmission belt 2 and the second transmission belt 3, so the glove 100 can rotate in the transmission channel 6, and the glove 100 can be continuously placed in the transmission channel 6.

[0034] In order to ensure that the glove 100 can be pulled into place, a preferred solution is to provide two or more pulling mechanisms along the transmission direction of the transmission channel 6 .

[0035] Specifically, in this embodiment, the two groups of pulling mechanisms respectively include a first pulling brush 7 and a second pulling brush 8, wherein the two first pulling brushes 7 near the entrance of the transmission channel 6 rotate relative to each other, and the two first pulling brushes 7 are respectively arranged on both sides of the glove in the transmission channel 6, and the two first pulling brushes 7 are respectively connected to the first pulling motor 9, and the two second pulling brushes 8 are respectively connected to the second pulling motor 10, and the two second pulling brushes 8 are also respectively arranged on both sides of the glove in the transmission channel 6.

[0036] When the first pulling brush 7 and the second pulling brush 8 pull the glove 100, it is necessary to ensure that the pulling force of the glove 100 is less than the resistance of the curling edge 101 passing through the transmission channel 6, otherwise the glove 100 will be separated from the transmission channel 6, resulting in adjustment failure. The pulling force of the brush on the glove 100 can be adjusted by adjusting the rotation speed of the brush by the first pulling motor 9 and the second pulling motor 10 and adjusting the distance between the two brushes.

[0037] Because the first transmission belt 2 and the second transmission belt 3 need to clamp the glove 100 for transmission, the width of the transmission channel 6 is relatively narrow. In order to ensure that the glove 100 smoothly enters the transmission channel 6, the entrances of the first transmission belt 2 and the second transmission belt 3 are set to be trumpet-shaped, and the glove 100 is sent into the transmission channel 6 through the trumpet-shaped entrance, which is convenient and reliable to operate.

[0038] In this embodiment, the pulling mechanism is arranged at the lower side of the glove transmission mechanism. The glove 100 is placed in the transmission channel 6 in a vertical manner. In order to further ensure that the glove 100 smoothly enters the transmission channel 6, a guide plate 11 is also provided on the upper side of the glove transmission mechanism. Two guide plates 11 are respectively arranged on both sides of the transmission channel 6. The spacing between the two guide plates 11 gradually decreases in the direction close to the posture adjustment channel, and the entrances of the two guide plates 11 are also arranged in a trumpet shape. The guide plate 11 has the function of introducing and straightening. The glove 100 can be smoothly transmitted into the transmission channel 6 through the trumpet-shaped entrance of the guide plate 11, and after the hand or robot that transfers the glove 100 is released, the upper part of the glove 100 is prevented from drooping down to the side of the first transmission belt 2 and the second transmission belt 3, but gradually moves downward in the transmission channel 6 with the help of the guide plate 11.

[0039] Working process: A human or robot puts the glove 100 into the transmission channel 6, and the first transmission belt 2 and the second transmission belt 3 drive the glove 100 to move in the transmission channel 6. At the same time, the two first pulling brushes 7 pull the glove 100 downward, so that the curling edge 101 of the glove 100 is stuck on the upper side of the first transmission belt 2 and the second transmission belt 3, and the other parts of the glove 100 are located on the lower side of the first transmission belt 2 and the second transmission belt 3. After the first pulling brush 7 finishes pulling, the second pulling brush 8 continues to pull the glove 100 to ensure that the curling edge 101 of the glove 100 is stuck on the upper side of the transmission channel 6, so as to ensure the smooth progress of the subsequent posture adjustment.

[0040] Example 2

[0041] See also Figure 4-5 The pulling mechanism in this embodiment includes a pulling brush and a back plate 12. The pulling brush and the back plate 12 are respectively arranged on both sides of the glove. The pulling brush and the back plate 12 cooperate to pull the glove to a predetermined position.

[0042] In order to ensure that the glove 100 can be pulled into place, the pulling brush in this embodiment also includes a first pulling brush 7 and a second pulling brush 8 arranged in sequence along the length direction of the transmission channel 6, the back plate 12 is fixedly arranged, and the first pulling brush 7 and the second pulling brush 8 are rotatably arranged, and the first pulling brush 7 and the second pulling brush 8 cooperate with the back plate 12 to pull the glove 100 to a predetermined position.

[0043] Example 3

[0044] See also Figures 6-8 The pulling mechanism in this embodiment includes a pulling cam 13 and a pulling motor 14 driving the pulling cam 13 to rotate. The two pulling cams 13 are arranged to rotate relative to each other, and each pulling cam 13 is connected to a pulling motor 14. When the glove 100 passes between the two pulling cams 13, the two pulling cams 13 squeeze the glove 100 and pull the glove 100 downward as they rotate. The time for each pulling cam 13 to pull the glove 100 downward is very short, rather than the continuous pulling method in Embodiments 1 and 2.

[0045] When continuously pulling the glove 100 downward, the clamping force needs to be considered. If the clamping force on the glove 100 is too large, the glove 100 is easily damaged and the glove 100 is also easy to fall off the transmission channel 6. If the clamping force is too small, it is not easy to pull the glove 100 down. In this embodiment, the glove 100 is temporarily pulled by the pulling cam 13, and the pulling cam 13 rotates three times during the glove 100 passing through the pulling cam 13, that is, the glove 100 is pulled downward three times. In this intermittent and temporary pulling of the glove 100, since the glove 100 is released in time after pulling, even if the force of clamping the glove 100 is too large, the glove 100 will not be damaged, nor will the glove 100 fall off the transmission channel 6, and the pulling is more reliable.

[0046] Example 4

[0047] The pulling mechanism in this embodiment is two relatively rotating rollers, which are respectively arranged on both sides of the glove in the transmission channel 6. The rotating rollers can also be used to pull the glove 100 downward into place.

[0048] It should be noted that the pulling mechanism is not necessarily arranged at the lower side of the transmission channel 6 , that is, the glove 100 does not necessarily have to be fed into the transmission channel 6 vertically.

[0049] The above are only preferred embodiments of the utility model, and are not intended to limit the utility model in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
