Description

Technical Field

[0001] The invention relates to the technical field of shoe processing machinery, and in particular to an auxiliary grasping device for preparing insoles. Background Art

[0002] Shoes are one of our daily wears, used to protect the feet and facilitate walking. Shoes are generally composed of uppers, outsoles, midsoles, insoles and other parts. Insoles are generally placed in shoes to make the shoes more comfortable to walk in. In the large-scale insole production process, large machines are generally used to directly cut the raw materials into shapes. However, the cut insoles are usually collected manually. The area of ​​the raw materials used for cutting is large, the number of insoles is large, the labor workload is large, and the speed of manual collection is limited, resulting in low overall processing efficiency of the insoles.

[0003] Existing invention patents, such as the application number CN201710951880.4, the publication date of 2018-03-27, and the name of the Chinese invention patent for an insole grabbing device, are mainly composed of a base plate 1, a mounting column 2, a movable plate 3, a bent plate 4, a needle 5 and other structures.

[0010] Furthermore, two glue boxes are fixedly connected to the lower surface of the cantilever, and the glue box is a hollow structure. Two third tubes are fixedly connected to the bottom wall of the glue box, and two second tubes are fixedly connected to the side wall of the functional block. One end of the second tube extends into the corresponding liquid cavity, and the other end extends to the outside of the functional block.

[0022] 5. When the main column rotates, the turntable is driven to rotate, and the pump plate is made to reciprocate through the push-pull plate, which continuously draws the air in the receiving box into the base, and then pumps it out through the seventh tube, thereby accelerating the air flow in the receiving box, so that the glue that falls on the internal insole can evaporate more quickly.

[0023] 6. While accelerating the flow of air in the receiving box, when the internal air is drawn into the base, the toxic substances after the volatilization of the glue are absorbed and purified by the activated carbon inside the base, and then discharged, thereby preventing the toxic substances after the volatilization of the glue from affecting the health of the processing personnel.

DETAILED DESCRIPTION

[0031] Reference Figure 1-6, an auxiliary grasping device for preparing insoles, comprising a hollow base 1 with one side open, a main column 2 is rotatably connected to the top wall of the base 1 through a bearing, a cantilever 3 is fixedly connected to the main column 2, a servo motor 6 is fixedly connected to the upper surface of the base 1, the servo motor 6 can periodically rotate 180° intermittently, thereby driving the main column 2 to rotate 180°, and its rotation frequency is consistent with the frequency of sending insoles by the insole processing device, which is a prior art and will not be described in detail here, the output shaft of the servo motor 6 is fixedly connected to a rotating rod 7, the rotating rod 7 and the main column 2 are both fixedly connected A gear 8 is connected, and the two gears 8 are meshed. The top wall of the cantilever 3 is fixedly connected with an electric push rod 4. The electric push rod 4 is an electromagnetic push rod, which outputs when powered on and automatically retracts when powered off. The output shaft of the electric push rod 4 is slidably connected to the cantilever 3 and is fixedly connected with a grabbing mechanism. Through the setting of two groups of grabbing mechanisms, one group of grabbing mechanisms grabs the insole while the other group of grabbing mechanisms places the grabbed insole, and the cycle is repeated. Therefore, while placing the grabbed insole, the next insole can be grabbed, so that the entire grabbing and placing process is continuous, further improving the processing efficiency.

[0032] The grabbing mechanism includes a functional block 9, which is fixedly connected to the output shaft of the corresponding electric push rod 4. Two sliding grooves 10 and two liquid chambers 13 are provided in the functional block 9. The functional block 9 is sealed and penetrated with two connecting columns 15 for sliding connection. One end of the connecting column 15 penetrates and extends into the corresponding sliding groove 10 and is fixedly connected with a push plate 11, and the other end penetrates and extends into the corresponding liquid chamber 13 and is fixedly connected with a piston plate 14. The piston plate 14 is sealed and slidably connected to the inner wall of the liquid chamber 13. A plurality of springs 12 are fixedly connected between the push plate 11 and the inner bottom wall of the sliding groove 10. Two first tubes 16 are penetrated and fixedly connected to the bottom wall of the functional block 9. One end of the first tube 16 penetrates and extends into the corresponding liquid chamber 13, and the other end penetrates and extends to the outside of the functional block 9 and is penetrated and fixedly connected with a fixed block 17. The fixed block 17 is a hollow structure and a grab block 18 is fixedly connected to the bottom wall. The functional block 9 moves downward and approaches the insole. At the same time, due to the movement of the functional block 9, under the elastic force of the spring 12, the back plate 11 moves upward, and drives the piston plate 14 to move upward through the connecting column 15. The piston plate 14 moves upward, and the glue in the liquid cavity 13 is pumped into the fixed block 17 through the first tube 16, and then enters the grab block 18. As the functional block 9 continues to move downward, the grab block 18 contacts the insole, and the insole is grabbed by the glue discharged from it. The insole is grabbed by the bonding of the glue. Compared with the prior art, the insole after grabbing will not leave holes like the prior art, so that the insole after grabbing is more beautiful, and the service life will not be reduced due to the presence of holes.

[0033] The functional block 9 is provided with a column groove 23, and the functional block 9 is sealed and slidably connected with a top column 24 through the column groove 23. Two fourth tubes 25 are fixedly connected through the functional block 9, and the fourth tube 25 connects the corresponding liquid cavity 13 with the column groove 23. The column groove 23 and the liquid cavity 13 are filled with hydraulic oil. The hydraulic oil in the liquid cavity 13 is filled between the piston plate 14 and the bottom wall of the liquid cavity 13. When the functional block 9 rises, the abutment plate 11 contacts the cantilever 3, so that the abutment plate 11 slides toward the sliding groove 10, thereby driving the piston plate 14 to move synchronously. The piston plate 14 pumps the hydraulic oil from the liquid cavity 13 into the column groove 23 through the fourth tube 25, so that the top column 24 slides out and pushes the grabbed insole down, thereby completing the automatic unloading of the insole.

[0034] Two glue boxes 20 are fixedly connected to the lower surface of the cantilever 3. The glue box 20 is a hollow structure. Two third tubes 21 are fixedly connected to the bottom wall of the glue box 20. Two second tubes 19 are fixedly connected to the side wall of the functional block 9. One end of the second tube 19 extends through the corresponding liquid cavity 13, and the other end extends through the outside of the functional block 9. A hose 22 is fixedly connected between the second tube 19 and the corresponding third tube 21. The glue box 20 is filled with glue. The setting of the hose 22 ensures that the second tube 19 and the third tube 21 are still connected during the movement of the functional block 9. The distance between the inner bottom wall of the glue box 20 and its top wall gradually increases from both sides to the center (such as Figure 5 As shown), the glue can be more concentrated at the third tube 21, which is convenient for suction. When the insole is pushed down, the movement of the piston plate 14 will also suck the glue in the glue box 20 into the liquid cavity 13 through the second tube 19, the hose 22, and the third tube 21, waiting to be pumped out, thereby automatically completing the glue replenishment.

[0035] A plurality of sixth tubes 30 are fixedly connected through the top wall of the base 1, and a receiving box 31 is slidably connected through the sixth tubes 30. The setting of the sixth tubes 30 can also position the receiving box 31, so that it is placed in the correct position to receive the fallen insoles.

[0036] A control mechanism is provided in the base 1, and the control mechanism includes a turntable 27, which is fixedly connected to one end of the main column 2 located in the base 1, and four conductive blocks 28 are fixedly connected to the side wall of the turntable 27, and two conductive rings 29 are fixedly connected to the inner side wall of the base 1, and each two conductive blocks 28 form a group, and the two groups of conductive blocks 28 are symmetrically arranged (such as Figure 3 As shown), the conductive ring 29 is not completely annular, but is arc-shaped (as shown in FIG. Figure 6As shown), when the main column 2 rotates, the conductive block 28 is driven to rotate to the left side so that the conductive block 28 contacts the conductive ring 29, and when the conductive block 28 rotates to the right side, the conductive block 28 and the conductive ring 29 are separated. The conductive block 28 is electrically connected to the corresponding electric push rod 4 through a wire, and the two conductive blocks 28 located on the same side are respectively connected to the positive and negative electrodes of the electric push rod 4 on the corresponding side, and the two conductive rings 29 are connected to the positive and negative electrodes of the power supply, so that when the conductive block 28 contacts the conductive ring 29, the corresponding electric push rod 4 can be energized. Through the control mechanism and the servo motor 6, when the main column 2 rotates, the cantilever 3 is driven to rotate. When it is necessary to grab the insole, the corresponding electric push rod 4 is automatically energized to grab the insole, and when it is necessary to place the insole, the corresponding electric push rod 4 is automatically powered off, and the grabbed insole is pushed down into the receiving box 31 through the top column 24, so that the grabbing and placing process is automated, and with the automated production equipment, the automation of the entire process is realized, which greatly reduces the labor intensity and improves the efficiency.

[0037] A ventilation mechanism is provided in the base 1, and the ventilation mechanism includes a pump plate 32, and the pump plate 32 is sealed and slidably connected to the inner wall of the base 1. A hole (not shown in the figure) is also opened on the side wall of the base 1 close to the turntable 27, so that the left side of the pump plate 32 is connected to the outside, thereby ensuring that the pump plate 32 in the sealed sliding connection can slide freely. A driving rod 33 is fixedly connected to the lower surface of the turntable 27, and a driven rod 34 is fixedly connected to the side wall of the pump plate 32. The driving rod 33 and the driven rod 34 are rotatably connected to the push-pull plate 3 through a bearing. 5. The side wall of the base 1 is fixedly connected with a sealing plate 37 by bolts, and a plurality of seventh tubes 38 are fixedly connected through the sealing plate 37. A plurality of threaded cylinders 39 are rotatably connected with the side wall of the sealing plate 37 through a bearing, and a plurality of stirring blades 40 are fixedly connected with the side wall of the threaded cylinder 39. A plurality of screws 36 are fixedly connected with the side wall of the pump plate 32 near the sealing plate 37. The screws 36 are threadedly connected with the corresponding threaded cylinders 39. The thread lead angle of the screw 36 is greater than the equivalent friction angle of the spiral pair formed by the screw 36 and the threaded cylinder 39, so that the screw 36 can drive the threaded tube 39 to rotate through a threaded connection. The base 1 is filled with activated carbon. The setting of the activated carbon can adsorb the toxic substances after the glue volatilizes and purify the air. The sealing plate 37 is fixed by bolts for easier disassembly. After the sealing plate 37 is disassembled, the activated carbon inside can be replaced. A sealing rubber ring is also provided at the contact point between the sealing plate 37 and the base 1 to avoid leakage at the contact point. When the main column 2 rotates and drives the turntable 27 to rotate, the pump plate 32 is driven to reciprocate through the push-pull plate 35. When the pump plate 32 moves toward the turntable 27, the air in the receiving box 31 is sucked into the base 1 through the sixth tube 30, and the toxic substances in the air are adsorbed and purified by the activated carbon. When the pump plate 32 moves in the direction away from the turntable 27, the air sucked into the base 1 and purified is discharged through the seventh tube 38, thereby accelerating the air flow in the receiving box 31, so that the glue on the internal insole can volatilize faster, so that the next processing procedure can be put into use more quickly, further improving the processing efficiency.

[0038] It is worth mentioning that, through the arrangement of the screw 36 and the threaded barrel 39 , a certain positioning effect can be achieved for the installation of the sealing plate 37 , so that the sealing plate 37 can be correctly installed, thereby better sealing the base 1 .

[0039] It is also worth mentioning that while the pump plate 32 is reciprocating, it can also be threadedly connected to the threaded barrel 39 through the screw 36, so that the threaded barrel 39 can reciprocate. The reciprocating rotation of the threaded barrel 39 drives the stirring blades 40 to reciprocate. The stirring blades 40 continuously stir the activated carbon inside, allowing it to come into more complete contact with the incoming air, thereby making the adsorption of toxic substances more thorough.

[0040] One-way valves are arranged in the first tube 16, the second tube 19, the fifth tube 26, the sixth tube 30 and the seventh tube 38. The one-way valve in the first tube 16 only allows glue to enter the fixed block 17 from the liquid cavity 13, the one-way valve in the second tube 19 only allows glue to enter the liquid cavity 13 from the second tube 19, the one-way valve in the fifth tube 26 only allows liquid and air to enter the glue box 20 from the outside, and the one-way valve in the fifth tube 26 prevents the glue in the glue box 20 from volatilizing into the air, the one-way valve in the sixth tube 30 only allows air to enter the base 1 from the receiving box 31, and the one-way valve in the seventh tube 38 only allows air to enter the outside from the base 1.

[0041] A protective cover 5 is fixedly connected to the upper surface of the base 1, and the main column 2 and the protective cover 5 are rotatably connected via a bearing. The provision of the protective cover 5, on the one hand, prevents the gear 8 from being exposed to the outside world and causing accidental injury, and at the same time protects the meshing of the gear 8. On the other hand, the protective cover 5 can play a certain supporting role on the main column 2, making it more stable during operation.

[0042] The glue filled in the glue box 20 is low-VOC glue, and the grabbing block 18 is made of porous sponge material. The grabbing block 18 made of porous sponge material can make the glue pumped out evenly and contact with the surface of the insole, so as to achieve a better grabbing effect. The low-VOC glue has strong volatility. After the bonding is completed, it can evaporate quickly (generally it can be completely evaporated after being exposed to the air for 2-3 hours). After volatilization, it will lose its adhesiveness, avoiding the glue remaining on the surface of the insole causing the collected insoles to be bonded together, affecting subsequent processing.

[0043] In the present invention, firstly, the glue box 20 is filled with glue through the fifth tube 26, and then the servo motor 6 is turned on. The servo motor 6 rotates through the meshing of the gear 8, driving the main column 2 to rotate. After the main column 2 rotates 180°, the functional block 9 on one side rotates to the top of the delivered insole. At the same time, the conductive block 28 on this side contacts the conductive ring 29, so that the electric push rod 4 on this side is energized and extended.

[0044] The electric push rod 4 extends, causing the functional block 9 to move downward and approach the insole. At the same time, due to the movement of the functional block 9, under the elastic force of the spring 12, the plate 11 moves upward, and drives the piston plate 14 to move upward through the connecting column 15. The piston plate 14 moves upward, and the glue in the liquid chamber 13 is pumped into the fixed block 17 through the first tube 16, and then enters the grab block 18. As the functional block 9 continues to move downward, the grab block 18 contacts the insole, and the insole is grabbed by the glue discharged from it.

[0045] After the insole is grabbed, the servo motor 6 starts and continues to drive the cantilever 3 to rotate 180 degrees, so that the functional block 9 after grabbing the insole rotates to the top of the receiving box 31, and the functional block 9 on the other side rotates to the top of the insole, and grabs it according to the above steps.

[0046] After the functional block 9 grabs the insole, it rotates to the top of the receiving box 31. At this time, the corresponding conductive block 28 is separated from the conductive ring 29. At this time, the electric push rod 4 is powered off and retracted, so that the functional block 9 rises. At the same time, the abutment plate 11 contacts the cantilever 3, so that the abutment plate 11 slides in the direction of the sliding groove 10, thereby driving the piston plate 14 to move synchronously. The piston plate 14 pumps the hydraulic oil from the liquid chamber 13 into the column groove 23 through the fourth tube 25, so that the top column 24 slides out, pushes the grabbed insole down, separates from the grabbing block 18, and falls into the receiving box 31. At the same time, the movement of the piston plate 14 will also suck the glue in the glue box 20 into the liquid chamber 13 through the second tube 19, the hose 22, and the third tube 21, waiting to be pumped out, and then the servo motor 6 continues to drive the main column 2 to rotate, and so on and so forth to complete the grabbing and placement of the insole.

[0047] When the main column 2 rotates and drives the turntable 27 to rotate, the pump plate 32 is also driven to reciprocate through the push-pull plate 35. When the pump plate 32 moves toward the turntable 27, the air in the receiving box 31 is sucked into the base 1 through the sixth tube 30, and the toxic substances in the air are adsorbed and purified by the activated carbon. When the pump plate 32 moves in the direction away from the turntable 27, the air sucked into the base 1 and purified is discharged through the seventh tube 38, thereby accelerating the air flow in the receiving box 31, so that the glue on the internal insole can evaporate faster.

[0048] While the pump plate 32 is reciprocating, it can also be threadedly connected to the threaded barrel 39 through the screw 36, so that the threaded barrel 39 can reciprocate. The reciprocating rotation of the threaded barrel 39 drives the stirring blade 40 to reciprocate. The stirring blade 40 continuously stirs the activated carbon inside, allowing it to come into contact with the incoming air more fully, thereby making the adsorption of toxic substances more thorough.
