Description

Technical Field

[0001] The utility model belongs to the technical field of shoe manufacturing, in particular to an automatic grabbing and placing device for shoe materials. Background Art

[0002] CN202123423581.4 discloses an automatic grasping and moving mechanism for the bottom iron plate used for forming the soles of security shoes, comprising a frame, an upper support frame is fixed on the top surface of the top plate of the frame, a rotary servo motor is fixed on the bottom surface of the top plate of the upper support frame, the output shaft of the rotary servo motor passes through the top surface of the top plate of the upper support frame and is fixed with a transverse rotating beam, a transverse fine-tuning mechanism is fixed to the bottom surface of the right end of the transverse rotating beam, a horizontal extension plate is fixed to the bottom surface of the fine-tuning moving block of the transverse fine-tuning mechanism, a lifting cylinder is fixed to the top surface of the right end of the horizontal extension plate, a push rod of the lifting cylinder passes through the bottom surface of the horizontal extension plate and is fixed with a connecting plate, and a vacuum suction cup is fixed to the bottom surface of the connecting plate.

[0003] In the above technical solution, the lifting cylinder is driven forward by the lateral fine adjustment mechanism, and then the lifting cylinder drives the connecting plate to descend, thereby driving the vacuum suction cup to descend, so as to take out the soles of the storage cylinder. Before work, workers often need to place a large pile of soles in the storage cylinder. If a storage cylinder with a large enough space is used to accommodate soles of various sizes, the soles cannot be positioned well. Then, the pile of soles is prone to tilt when placed. In this way, after the vacuum suction cup takes the material, it is not flat when placed, and it is difficult to position the soles well.

[0004] Moreover, if this method is used to absorb lighter shoe materials, the edges of the shoe materials may be blown up under the suction of the suction cup and cannot be in a straight state, causing the blown-up part to fold. In this way, when the lifting cylinder drives the vacuum suction cup to descend to absorb the shoe materials, the shoe materials cannot be placed flat on the conveyor belt, and the method of frequently opening and closing the suction cup is also very inconvenient. Utility Model Content

[0005] The utility model aims to solve the above-mentioned problems and provides an automatic shoe material grabbing and placing device. The device utilizes a fixed rod that is movable and adjustable in a supporting plate, so that the fixed rod can be adjusted according to the size of the shoe material on the placement portion, thereby fixing and positioning the shoe material. The supporting plate is driven to rise by a lifting mechanism, so that the shoe material in the placement portion can be pressed tightly under the bent portion of the fixed rod after the material taking mechanism takes the material each time. In this way, the height difference between the shoe material and the material taking mechanism can be reduced and the shoe material can be avoided from being lifted up by the material taking mechanism during adsorption. Moreover, when the suction force is too large, the shoe material lifted up by the pressure will be blocked by the bent portion of the fixed rod, so that it returns to the placement portion.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The side surfaces of the plurality of fixing rods are in contact with the edges of the shoe material on the placement portion to form a receiving chamber matching the shape of the shoe material;

[0009] The horizontal driving mechanism is used to drive the material taking mechanism to move back and forth between the containing chamber and the conveying mechanism.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] refer to Figures 1 to 4 , an automatic grabbing and releasing device for shoe materials, comprising a frame 1, a conveying mechanism 2, a material taking mechanism 3, a support plate 4, and a plurality of fixed rods 5, wherein the conveying mechanism 2 is connected to the frame 1, a horizontal driving mechanism 11 is provided on the frame 1, the material taking mechanism 3 is connected to the horizontal driving mechanism 11, and is located above the conveying mechanism 2, a lifting mechanism 12 is also provided on the frame 1, the support plate 4 is connected to the lifting mechanism 12, a placement portion 42 is provided on the support plate 4, the plurality of fixed rods 5 are movably connected in the support plate 4, and are arranged around the placement portion 42, a bending portion 52 inclined along the center of the placement portion 42 is provided on the top of the fixed rod 5, and the bottom of the fixed rod 5 is detachably connected to the frame 1;

[0019] The side surfaces of the plurality of fixing rods 5 are in contact with the edge of the shoe material on the placement portion 42 to form a receiving chamber 43 matching the shape of the shoe material;

[0020] The horizontal driving mechanism 11 is used to drive the material taking mechanism 3 to move back and forth between the containing chamber 43 and the conveying mechanism 2;

[0021] It should be noted here that the material taking mechanism 3 is a prior art, which takes materials by generating suction through negative pressure.

[0022] Under this design, the worker first places the shoe material on the placement portion 42, and then adjusts the position of the fixing rod 5 to make the side of the fixing rod 5 contact with the edge of the shoe material, so that the fixing rod 5 completes the fixation of the shoe material, and the shoe material will be pressed tightly by the bent portion 52 of the fixing rod 5, and then the horizontal driving mechanism 11 is started to drive the material taking mechanism 3 to move to the placement portion 42, and then the material taking mechanism 3 absorbs and takes out the shoe material on the placement portion 42 and places it on the conveying mechanism 2. The horizontal driving mechanism 11 will repeatedly drive the material taking mechanism 3 to move back and forth between the placement portion 42 and the conveying mechanism 2, so that the conveying mechanism 2 can send the shoe material to the next processing step, and each time the material taking mechanism 3 moves During each material picking operation, there will be a height difference between the uppermost shoe material and the bent portion 52 of the fixed rod 5. Therefore, the lifting mechanism 12 drives the support plate 4 to rise to shorten the distance, so that the shoe material on the placement portion 42 is always pressed against the bottom of the bent portion 52 of the fixed rod 5. In this way, the height difference between the shoe material and the material picking mechanism 3 can be reduced and the shoe material can be avoided from being lifted up during the adsorption of the material picking mechanism 3. When the material picking mechanism 3 hovers above the shoe material waiting for material picking, the adsorption function cannot be frequently switched on and off. Therefore, the material picking mechanism 3 still has the ability to adsorb when hovering. The pressure brought by the adsorption limits the shoe material under the action of the bent portion 52 of the fixed rod 5 to avoid the edge of the shoe material being blown up.

[0023] In this embodiment, the lifting mechanism 12 includes a first motor 123 and a screw rod 122 connected to the frame 1, a first slider 121 is provided on the screw rod 122, and the support plate 4 is connected to the first slider 121;

[0024] Furthermore, by using the first motor 123 to drive the first slider 121 to rise, thereby driving the support plate 4 to rise, the height difference between the material taking mechanism 3 and the shoe material in the placement portion 42 can be reduced, and the screw rod 122 plays a role in guiding the moving direction of the first slider 121.

[0025] More preferably, a first suction cup 51 is provided at the bottom of the fixing rod 5, and the fixing rod 5 is detachably connected to the frame 1 through the first suction cup 51; after adjusting the position of the fixing rod 5, it is necessary to fix the fixing rod 5 to prevent it from moving, so the fixing rod 5 is detachably connected to the frame 1 by forming a negative pressure in the first suction cup 51 using the first suction cup 51.

[0026] In this embodiment, a second slider 6 is included, and the frame 1 is also provided with a support seat 13, the support seat 13 is located on both sides of the support plate 4, and a guide column 131 is provided on the support seat 13, and the second slider 6 is movably connected to the guide column 131 and connected to the support plate 4.

[0027] Specifically, in order to ensure the balance of the support plate 4 when it rises, the second slider 6 is connected to both sides of the support plate 4, so that the second slider 6 can follow the rise of the support plate 4 on the guide column 131, thereby improving the balance of the support plate 4 during movement.

[0028] More preferably, the support plate 4 is provided with a plurality of slide grooves 41, the fixing rod 5 is movably connected in the slide groove 41 and can be adjusted along the direction of the slide groove 41, and the bending direction of the bending portion 52 is consistent with the length direction of the slide groove 41;

[0029] Furthermore, the fixing rod 5 can move in the slide groove 41, so that the worker can adjust the position of the fixing rod 5 according to the size of the shoe material, so as to fix and position the shoe material, and the bending direction of the bending portion 52 is consistent with the length direction of the slide groove 41 to avoid the bending portion 52 blocking the rising of the support plate 4 when the support plate 4 rises.

[0030] In this embodiment, the horizontal driving mechanism 11 includes a slide rail 111 connected to both sides of the frame 1, a third slider 112 matching the slide rail 111, a second motor (not shown in the figure) for driving the third slider 112, and a fixed plate 113 connected between the second sliders 6, and the material picking mechanism 3 is connected to the fixed plate 113.

[0031] Specifically, the movement of the third slider 112 is driven by the second motor, thereby driving the material taking mechanism 3 to move back and forth between the placement portion 42 and the conveying mechanism 2, so that the material taking mechanism 3 can place the shoe material taken from the placement portion 42 on the conveying mechanism 2, so that the conveying mechanism 2 can deliver the shoe material to the next processing step.

[0032] Preferably, the material picking mechanism 3 includes a first cylinder 31 connected to the fixed plate 113, a fixing frame 32 connected to the output end of the first cylinder 31, a telescopic rod 33 floatingly connected to the bottom of the fixing frame 32, and a second suction cup 34 connected to the bottom of the telescopic rod 33.

[0033] Furthermore, since there is a height difference between the shoe material in the placement portion 42 and the material picking mechanism 3, the first cylinder 31 drives the fixing frame 32 downward so that the second suction cup 34 can adsorb and fix the shoe material. After the second suction cup 34 takes out the shoe material, the first cylinder 31 drives the second suction cup 34 to reset, and then the horizontal driving mechanism 11 drives the second suction cup 34 to move to the conveying mechanism 2. Subsequently, the second suction cup 34 releases the fixation of the shoe material and places it on the conveying mechanism 2. After being placed on the conveying mechanism 2, the horizontal driving mechanism 11 drives the second suction cup 34 to move to the placement portion 42 again for the next material picking.
