Description

Technical Field

[0001] This utility model relates to the field of glove production, and in particular to a glove posture straightening mechanism, a glove feeding mechanism, and a glove turning machine. Background Technology

[0002] Gloves are a widely used type of work protection product. They are generally produced by knitting gloves using glove knitting machines. After the gloves are produced by the glove knitting machine, they undergo subsequent processes, such as identifying defective gloves using automatic visual recognition equipment, bundling gloves using automatic glove bundling and packaging equipment, and turning gloves over using automatic glove turning equipment.

[0003] In various processes after glove production, it is often necessary to load the gloves. For example, when turning gloves over, the existing technology generally involves placing a stack of gloves on a movable platform (such as a conveyor belt), conveying the stack of gloves to the designated position, and then using a glove loading mechanism to grab the top glove and move it to a designated position (such as the glove opening station) for turning the glove over.

[0004] In actual use, when the glove feeding mechanism feeds the gloves from the glove stack to the designated position, the gloves are made of flexible fabric and their posture often changes under the action of the feeding mechanism, which makes it impossible to continue subsequent processes such as glove opening. Utility Model Content

[0005] To address the problems of existing technologies, this utility model provides a glove posture sorting mechanism, a glove feeding mechanism, and a glove turning machine, ensuring the correct glove posture at the feeding and receiving station.

[0006] The technical solution provided by this utility model is as follows:

[0007] A glove posture adjustment mechanism includes at least one feeding and receiving station. Each feeding and receiving station has a glove clamp on each side. The glove clamp is connected to a clamp driving mechanism, which controls the two glove clamps at the same feeding and receiving station to move closer or further apart.

[0008] Furthermore, the feeding and receiving station is located on the feeding and receiving platform, the clamping plate driving mechanism is located below the feeding and receiving platform, the glove clamp is vertically arranged and passes through the feeding and receiving platform, the lower part of the glove clamp is located below the feeding and receiving platform and is connected to the clamping plate driving mechanism, and the upper part of the glove clamp is located above the feeding and receiving platform.

[0009] Furthermore, the feeding and receiving platform is provided with a number of strip-shaped relief grooves, and the glove clamp is provided with strip-shaped ribs in the middle, the number of which is the same as the number of strip-shaped relief grooves. The strip-shaped ribs are located in the strip-shaped relief grooves, so that the glove clamp passes through the feeding and receiving platform.

[0010] A glove feeding mechanism includes a glove gripping device and the glove posture adjusting mechanism, wherein:

[0011] The glove gripping device is used to grip the gloves to the feeding and receiving station. The glove gripping device includes a swing arm. One end of the swing arm swings under the drive of the swing arm motor. The other end of the swing arm is a free end. A mounting base is provided on the free end of the swing arm. A first gripping unit is provided on the mounting base.

[0012] The swing arm drives the first gripping unit to swing back and forth, and the first gripping unit maintains the same posture during the swing of the swing arm.

[0013] Furthermore, the swing arm includes a swing arm connector, a first synchronous pulley, and a second synchronous pulley. One end of the swing arm connector is connected to the drive shaft of the swing arm motor, and the other end is connected to the mounting base. The first synchronous pulley and the second synchronous pulley are respectively mounted on the drive shaft of the swing arm motor and the mounting base, and the first synchronous pulley and the second synchronous pulley are connected by a synchronous belt.

[0014] Furthermore, each material receiving station is equipped with a second gripping unit, which is located between two glove clamps at the same material receiving station. The material receiving platform has a notch at the second gripping unit, and the second gripping unit is located within the notch.

[0015] Furthermore, a sensor is installed above each material receiving station to detect whether there are gloves on the material receiving station and / or whether the position of the gloves meets the requirements.

[0016] Furthermore, the sensor is a photoelectric sensor, the detection direction of the photoelectric sensor is vertically downward, and a reflective sticker is affixed to the upper surface of the material receiving station.

[0017] Furthermore, the first gripping unit is provided with an inclined glove pressure plate, and the feeding and receiving station is provided with a support block. The top surface of the support block has an inclined support surface, and the inclination angle of the support surface is the same as the inclination angle of the glove pressure plate.

[0018] Furthermore, a vertical baffle is provided on each side of the supporting surface.

[0019] A glove turning machine includes the aforementioned glove feeding mechanism.

[0020] This utility model has the following beneficial effects:

[0021] This invention features a glove clamp on each side of the glove loading and receiving station. After the glove loading mechanism loads the gloves from the glove stack to the receiving station, the clamp drive mechanism controls the two clamps to move closer together by a certain distance. The clamps then adjust the glove's posture by clamping it against each other, essentially pushing the sides of the glove inwards to restore it to the required position. This ensures the correct glove posture at the receiving station and guarantees the smooth operation of subsequent processes. Attached Figure Description

[0022] Figure 1 This is a perspective view of the glove feeding mechanism of this utility model;

[0023] Figure 2 This is a bottom view of the glove feeding mechanism of this utility model. Detailed Implementation

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] This utility model embodiment provides a glove posture adjustment mechanism, such as... Figure 1-2 As shown, it includes at least one feeding and receiving station 1. Each feeding and receiving station 1 has a glove clamp 2 on each side. The glove clamp 2 is connected to a clamp driving mechanism 3. The clamp driving mechanism 3 is used to control the two glove clamps 2 of the same feeding and receiving station 1 to move closer or further apart.

[0026] This invention features a glove clamp on each side of the glove loading and receiving station 1. When the glove loading mechanism loads the gloves from the glove stack to the receiving station 1, the clamp drive mechanism 3 controls the two glove clamps 2 to move closer together by a certain distance. The two clamps 2 adjust the glove's posture by clamping it closer to each other, essentially pushing the sides of the glove inwards to restore it to the required posture. This ensures the correct glove posture at the receiving station and guarantees the smooth progress of subsequent processes (such as opening the gloves).

[0027] Please note that after clamping the glove inwards, this invention generally restores the glove to the correct posture, but not strictly to the required posture. In fact, because the glove is made of flexible fabric, it is impossible to restore it to a strictly specified posture. As long as it is generally restored to the required posture, it can ensure that subsequent processes can proceed.

[0028] In a specific example, the material receiving station 1 is located on the material receiving platform 4, the clamping drive mechanism 3 is located below the material receiving platform 4, the glove clamp 2 is vertically arranged and passes through the material receiving platform 4, the lower part of the glove clamp 2 is located below the material receiving platform 4 and is connected to the clamping drive mechanism 3, and the upper part of the glove clamp 2 is located above the material receiving platform 4 for glove posture adjustment.

[0029] To ensure the glove clamp 2 passes through the loading platform 4, the loading platform 4 is provided with several strip-shaped clearance grooves 5. When there are multiple strip-shaped clearance grooves 5, they form a grid-like structure. The glove clamp 5 has strip-shaped reinforcing plates 6 in the middle, the number of which matches the number of strip-shaped clearance grooves 5. When there are multiple strip-shaped reinforcing plates 6, there are gaps between them, also forming a grid-like structure. The strip-shaped reinforcing plates 6 are located within the strip-shaped clearance grooves 5, allowing the glove clamp 2 to pass through the loading platform 4. The strip-shaped clearance grooves 5 also play a guiding and limiting role during the movement of the glove clamp 2.

[0030] This utility model does not limit the specific structural form of the clamping plate drive mechanism 3. In one example, the clamping plate drive mechanism 3 is a cylinder, and each clamping plate drive mechanism 3 is connected to a cylinder. Of course, the clamping plate drive mechanism 3 can also be other power mechanisms capable of linear displacement, such as a motor (and its equipped gear, rack, lead screw and other transmission mechanisms), hydraulic cylinder, electric cylinder, etc. This utility model does not limit these.

[0031] Chinese patent document CN219361462U discloses a glove feeding mechanism that needs to move vertically and then horizontally when grabbing gloves. It requires a large number of actuators to achieve the above action process. Each actuator needs to have an independent control source and a control relationship with each other. The structure is relatively complex and occupies a lot of space due to the large number of actuators, resulting in low execution efficiency.

[0032] To address the aforementioned problems, this utility model embodiment also provides a glove feeding mechanism, such as... Figure 1-2 As shown, it includes a glove gripping device and the aforementioned glove posture adjustment mechanism, wherein:

[0033] The glove gripping device is used to grip gloves and place them at the loading and receiving station 1. Specifically, it can grip the top layer of gloves from a stack of gloves and place them at the loading and receiving station 1. The stack of gloves can be a simple stack of gloves, a stack of gloves on a conveyor belt, or a stack of gloves in a glove receiving box as described in CN219361462U. This utility model does not impose any limitations, as long as the device can grip the gloves.

[0034] The glove gripping device includes a swing arm 7, one end of which swings under the drive of a swing arm motor (not shown), and the other end of the swing arm 7 is a free end. A mounting base 8 is provided on the free end of the swing arm 7, and a first gripping unit 9 is provided on the mounting base 8.

[0035] The swing arm 7 drives the first gripping unit 9 to swing back and forth. Specifically, it swings back and forth between the aforementioned stack of gloves and the loading and receiving station 1. During the swing of the swing arm 7, the first gripping unit 9 always maintains the same posture. That is, when the first gripping unit 9 reaches the loading and receiving station 1, it maintains the loading posture at the aforementioned stack of gloves, which is the vertical downward posture.

[0036] This invention changes the traditional vertical and horizontal movement when grasping gloves, and uses a reciprocating swing method to grasp the gloves, which can effectively reduce structural complexity and workflow, greatly improve execution efficiency, and reduce space occupation.

[0037] This utility model does not limit the specific structural form of the swing arm 7. In one example, the swing arm 7 includes a swing arm connector 10, a first synchronous pulley 11 and a second synchronous pulley 12. One end of the swing arm connector 10 is connected to the drive shaft 13 of the swing arm motor, and the other end is connected to the mounting base 8.

[0038] The first synchronous pulley 11 and the second synchronous pulley 12 are respectively mounted on the drive shaft 13 of the swing arm motor and the mounting base 8. The first synchronous pulley 11 and the second synchronous pulley 12 are connected by a synchronous belt (not shown). Through the synchronous belt, the first gripping unit 9 on the mounting base 8 always maintains the same posture during the swing of the swing arm 7, that is, always maintains a vertical downward posture.

[0039] The number of swing arm connectors 10 can be two, with the first synchronous pulley 11 and the second synchronous pulley 12 located between the two swing arm connectors 10.

[0040] After the gloves are picked up at the feeding and receiving station 1 and their posture is adjusted by the glove clamps 2, the heel of the gloves needs to be opened so that the subsequent glove opening mechanism can be inserted into the heel of the gloves to perform the opening operation. Therefore, a second gripping unit 14 is provided at each feeding and receiving station 1. The second gripping unit 14 is located between the two glove clamps 2 at the same feeding and receiving station 1. Specifically, the feeding and receiving platform 4 has a notch 15 at the second gripping unit 14, and the second gripping unit 14 is located within the notch 15.

[0041] Please note that in this invention, after the glove is gripped by the first gripping unit 9 and placed at the feeding receiving station 1, the first gripping unit 9 releases its grip on the glove, and then the glove's posture is adjusted by the glove clamp 2. After the glove's posture is adjusted, the first gripping unit 9 and the second gripping unit 14 grip the upper and lower surfaces of the glove respectively, and then the first gripping unit 9 moves upward a certain distance to open the base of the glove.

[0042] The first gripping unit 9 and the second gripping unit 14 described in this utility model are gripping devices capable of gripping soft fabrics. For example, they can be needle suction cups or other gripping devices, as long as they can grip gloves. This utility model does not limit them in this regard.

[0043] As an improvement of this utility model embodiment, a sensor 16 is provided above each material receiving station 1. The sensor 16 is used to detect whether there are gloves on the material receiving station 1 and / or whether the position of the gloves meets the requirements.

[0044] Specifically, sensor 16 is a photoelectric sensor with a vertically downward detection direction. When there are no gloves on the loading station 1, the light signal from the photoelectric sensor shines on the surface of the loading station 1, and the reflected light signal is received by the photoelectric sensor, thus determining that there are no gloves on the loading station 1. To enhance the reflective effect, reflective tape 17 can be attached to the surface of the loading station. When there are gloves on the loading station 1, the light signal from the photoelectric sensor shines on the gloves. Since the light signal undergoes diffuse reflection on the gloves, the reflected signal intensity is low and insufficient to trigger the photoelectric sensor, thus determining that there are gloves on the loading station 1. The sensitivity of the photoelectric sensor is adjustable, and can be adjusted to a level where the reflected light from the gloves does not trigger the photoelectric sensor.

[0045] Chinese patent document CN220200808U discloses a rotary feeding device for glove processing, which realizes oscillating rotary feeding. However, during the rotary feeding process, after the first gripping unit grips the glove, due to the rotation, when the glove reaches the feeding receiving station 1, it is prone to flipping over due to inertia. To solve this problem, this utility model provides an inclined glove pressure plate 18 on the first gripping unit 9. During the rotary feeding process, the glove pressure plate 18 can prevent the glove from flipping over due to inertia.

[0046] Correspondingly, a support block 19 is provided on the material receiving station 1. The top surface of the support block has an inclined support surface 20. The inclination angle of the support surface 20 is the same as the inclination angle of the glove pressure plate 18, which makes it convenient to place the gloves on the material receiving station 1.

[0047] The swing-type glove gripping device of this utility model can adopt various structural forms disclosed in CN220200808U, which will not be described in detail here.

[0048] A vertical baffle 21 is provided on each side of the support surface 20. When the glove is grabbed and placed on the feeding and receiving station 1, the two vertical baffles 21 can generally restrict the glove and generally adjust its posture.

[0049] The position of the aforementioned reflective sticker 17 can be set according to the size of the gloves and actual needs. For example, it can be set between the two glove clamps 2, and between the second gripping unit 14 and the support block 17. The reflective sticker at this position can detect whether there are gloves on the loading and receiving station 1. When the position of the gloves is greatly deviated, the reflective sticker 17 at this position cannot be covered by the gloves, so it can still be detected when the position of the gloves is greatly deviated.

[0050] In this invention, the number of glove posture adjustment mechanism and glove feeding mechanism can be one or more, which can simultaneously realize the feeding or posture adjustment of one or more gloves, thereby improving efficiency.

[0051] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
