Description

Technical Field

[0001] The present invention relates to the technical field of lifting and transferring, and in particular to a method and device for pneumatic lifting and transferring of double-stations on the same track. Background Art

[0002] In product processing, for two processing stations, each needs to be equipped with an independent loading and unloading mechanism. The two independent mechanisms are not convenient for reaching the other station to pick up materials. When encountering a shortage of materials at their own station, they can only wait, resulting in low production efficiency; when picking up and placing materials, it is necessary to drive the clamping component to move downward to pick up and place the material to be processed, and the stroke required to drive the clamping component up and down is relatively long; if the material to be processed is not straight, it must be corrected before taking it out, or, if the material to be processed has been taken out, it is necessary to first loosen the material to be processed, then put it down, and then correct the material to be processed and then clamp it again, which will lead to low transfer efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of existing devices such as being inconvenient for picking up materials from each other when there is a shortage of materials and sometimes requiring waiting; a long stroke is required to drive the clamping parts to move up and down; and the need to correct the materials to be processed in advance, the present invention provides a method and device for pneumatic lifting and transferring on the same track with double stations, which can pick up materials from each other when there is a shortage of materials without waiting, and can shorten the moving stroke of the clamping parts, and can also perform more comprehensive corrections on the materials during the movement, without the need to correct the materials to be processed in advance, thereby improving the transfer efficiency.

[0005] Optionally, the pre-lowering mechanism includes a guide block, the guide block is fixedly connected to the side of the sliding block away from the cylinder, two guide frames are fixedly connected to the bracket, the two guide frames are staggered, one end of the guide frame is tilted downward, and guide grooves are provided on both guide frames, the lower part of one of the guide blocks is located in the guide groove of one of the guide frames, and the lower part of the other guide block is located in the guide groove of the other guide frame.

[0006] Optionally, the preliminary adjustment mechanism includes a ladder frame, ladder frames are fixedly connected to both sides of the bottom of the connecting frame, rack frames are slidably provided on the two ladder frames, a return spring is connected between the rack frame and the ladder frame, an inclined frame is slidably provided in the middle of the connecting frame, a top block is fixedly connected to one side of the middle of the bracket, the inclined frame will contact the top block, and swing clamps for preliminary adjustment of the material to be processed are rotatably installed on both sides of the connecting frame, a limiting slot is provided on the swing clamp, and the end of the rack frame away from the connecting frame is located in the limiting slot of the swing clamp, a clamping plate is rotatably connected to the swing clamp, and a torsion spring is connected between the clamping plate and the swing clamp.

[0007] Optionally, a secondary adjustment mechanism is also included, which is arranged on the ladder frame. The secondary adjustment mechanism is used to further adjust the material to be processed. A column gear is rotatably installed in the middle of the top of the ladder frame, and the column gear is engaged with the rack frame. Triangular slides are slidably installed on both sides of the ladder frame, and a driving rack is fixed on the side where the two triangular slides are close to each other. The two driving racks are staggered and both driving racks are engaged with the column gear. The lower part of the triangular slide is slidably connected to an adjustment plate, and a guide groove is opened at the lower part of the ladder frame. The upper part of the adjustment plate is located in the guide groove.

[0008] Optionally, a leveling mechanism is also included, which is arranged on the connecting frame, and a lifting frame is fixedly connected to the triangular slide. Both sides of the lower part of the connecting frame are slidingly provided with lifting frames, and two vertical springs are connected between each of the lifting frames and the bottom of the connecting frame, and the lifting frame is in contact with the lifting frame.

[0009] Optionally, balls are also included, and a plurality of balls are provided on the sides of the two adjustment plates that are close to each other.

[0010] Optionally, the following steps are included:

[0011] Step 1: First, the operator feeds the material to the conveying equipment, and then the material is processed by the processing equipment.

[0012] Step 2: Then, when one of the conveying devices is short of material, the electric suction cup at the location with sufficient material supply continues to unload material in the working area of ​​this workstation. Then the operator starts the electric slider at the location with insufficient material supply and moves it along the guide rail to the top of the conveying device at the location with sufficient material supply to pick up the material. Then, the sucked material to be processed is moved to the conveying device with insufficient material supply.

[0013] Step 3: Finally, the movement of the rack will push the lower parts of the two swing clamps to swing towards each other. When the two swing clamps move toward the middle and touch the two sides of the material to be processed, the operator turns off the electric suction cup. As the two swing clamps move toward the middle, two sides of the material to be processed can be corrected.

[0014] The beneficial effects are:

[0015] When the material is insufficient, the electric suction cup at the insufficient feeding position continues to unload the material in the working area of ​​this station. Then the operator starts the electric slide block at the insufficient feeding position and moves it along the guide rail to above the conveying equipment at the sufficient feeding position. When the electric suction cup moves to the top of the material to be processed, the operator closes the electric slide block and starts the telescopic rod of the cylinder to extend. The telescopic rod of the cylinder drives the connecting frame and the electric suction cup to move downward. When the electric suction cup absorbs the material to be processed, the operator adjusts the telescopic rod of the cylinder to retract and drive the connecting frame and the electric suction cup to reset. Then the operator adjusts the electric slide block to reset. The electric slide block drives the sliding block, the connecting frame, the cylinder, the electric suction cup and the sucked material to be processed to the conveying equipment with insufficient feeding. Then the electric slide block is closed and the electric suction cup is closed, so that the sucked material to be processed is moved to the conveying equipment with insufficient feeding. By driving the electric suction cup at the insufficient feeding position to the conveying equipment with sufficient feeding to pick up the material, and placing it on the conveying equipment with insufficient feeding, the waiting time for processing is fully utilized and the loading efficiency is improved.

[0016] 2. By starting the electric slider at the insufficient feeding position, it moves along the guide rail to above the conveying equipment at the sufficient feeding position. The movement of the electric slider drives the connecting frame to move, the connecting frame drives the guide block to move, and the guide block moves along the guide frame. When the guide block moves to the downward inclined position of the guide frame, the guide block will move downward under the action of the guide frame, and the downward movement of the guide block will drive the connecting frame to move downward. The connecting frame drives the cylinder and the electric suction cup to move downward a certain distance, which can make the electric suction cup closer to the material to be sucked, thereby shortening the extension distance of the cylinder, and further shortening the time for the electric suction cup to absorb the material to be processed.

[0017] 3. By driving the two swing clamps and the clamping plate to correct the material to be processed, the material to be processed sucked by the electric suction cup can be made more orderly, and the material to be processed put down after transfer can also be made more orderly. The time of transferring the material to be processed is fully utilized to correct the material to be processed. The material to be processed does not need to be corrected before being adsorbed, which can improve the efficiency of clamping the material to be processed and thus improve the efficiency of transferring the material to be processed.

[0018] When the two triangular slides move toward each other, the two triangular slides will drive the ejecting frames to move toward each other, and the two ejecting frames will drive the ejecting frames to move downward, and the vertical springs will be stretched. The ejecting frames move downward, so that the material to be processed can be corrected in the vertical direction. When the material to be processed moves downward, the material to be processed will push the splint to expand outward, and the torsion spring will twist accordingly, which can reduce the friction between the material to be processed and the splint, and reduce the surface wear or damage probability of the material to be processed during the correction process. After the material to be processed is corrected, under the action of the torsion spring, the splint can still fit tightly with two side surfaces of the material to be processed; when the two triangular slides move toward the direction away from each other, the two triangular slides will drive the ejecting frames to move toward each other, and under the action of the vertical springs, the two ejecting frames will drive the ejecting frames to reset upward. Under the action of the ejecting frames, the material to be processed can be further corrected, thereby further improving the efficiency of transferring the material to be processed.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: A device and method for pneumatic lifting and transferring of double-stations on the same track, such as Figures 1-13As shown, it includes a bracket 1, the top of the bracket 1 is connected to a guide rail 2 by bolts, two electric sliders 3 are slidably installed on the guide rail 2, and the two electric sliders 3 are slidably connected to a sliding block 4, one side of the sliding block 4 is slidably connected to a connecting frame 5, and the other side of the sliding block 4 is connected to a cylinder 6 by bolts, and the end of the telescopic rod of the cylinder 6 is connected to the middle of the connecting frame 5, and eight electric suction cups 7 for adsorbing materials to be processed are evenly spaced at the bottom of the connecting frame 5. Two processing equipment 72 for processing materials are provided on one side of the bracket 1, and two conveying equipment 71 for conveying materials are provided on the other side of the bracket 1. A pre-lowering mechanism for early lowering is provided on the connecting frame 5, and preliminary adjustment mechanisms for adjusting the materials to be processed are provided on both sides of the connecting frame 5.

[0035] The pre-lowering mechanism includes a guide block 81, and the guide block 81 is fixedly connected to the side of the sliding block 4 away from the cylinder 6. Two guide frames 82 are fixedly connected to the bracket 1. The two guide frames 82 are staggered, and one end of the guide frame 82 is tilted downward. Guide grooves are provided on both guide frames 82. The lower part of one of the guide blocks 81 is located in the guide groove of one of the guide frames 82, and the lower part of the other guide block 81 is located in the guide groove of the other guide frame 82. The guide block 81 will be guided along the path of the guide frame 82.

[0036] The preliminary adjustment mechanism includes a ladder frame 91, and ladder frames 91 are fixedly connected to both sides of the bottom of the connecting frame 5. Rack frames 92 are slidably provided on the two ladder frames 91, and a return spring 93 is connected between the rack frame 92 and the ladder frame 91. A slope frame 94 is slidably provided in the middle of the connecting frame 5, and a top block 95 is installed on one side of the middle of the bracket 1 by bolts. The slope frame 94 will contact the top block 95. Swing clamps 96 for preliminary adjustment of the material to be processed are rotatably installed on both sides of the connecting frame 5. A limiting slot is provided on the swing clamp 96, and the end of the rack frame 92 away from the connecting frame 5 is located in the limiting slot of the swing clamp 96. The end of the rack frame 92 is slidably provided on the upper part of the swing clamp 96, and a clamp plate 97 is rotatably connected to the swing clamp 96. A torsion spring 98 is connected between the clamp plate 97 and the swing clamp 96.

[0037] The two conveying devices 71 supply the same material to be processed, and the processing equipment 72 can be equipment for processing different products. When the two conveying devices 71 have sufficient supply, the electric suction cup 7 operates at its respective workstation. When one of the conveying devices 71 has insufficient supply, the electric suction cup 7 at the location with sufficient supply continues to unload materials in the working area of ​​this workstation. Then the operator starts the electric slider 3 at the location with insufficient supply and moves it along the guide rail 2 to above the conveying device 71 at the location with sufficient supply. The movement of the electric slider 3 drives the connecting frame 5 to move, and the connecting frame 5 drives the guide block 81 to move. The guide block 81 moves along the guide frame 82. When the guide block 81 moves to the downward inclined position of the guide frame 82, the guide block 81 will move downward under the action of the guide frame 82. The downward movement of the guide block 81 will drive the connecting frame 5 to move downward, and the connecting frame 5 drives the cylinder 6 and the electric suction cup 7 to move downward a certain distance, so that the electric suction cup 7 can be closer to the material to be processed that needs to be sucked, thereby shortening the extension of the cylinder 6. When the material is above the loading platform 7, the operator closes the electric slide block 3, and the operator starts the telescopic rod of the air cylinder 6 to extend, and the telescopic rod of the air cylinder 6 drives the connecting frame 5 and the electric suction cup 7 to move downward. When the electric suction cup 7 absorbs the material to be processed, the operator adjusts the telescopic rod of the air cylinder 6 to retract and drive the connecting frame 5 and the electric suction cup 7 to reset. Then the operator adjusts the electric slide block 3 to reset. The electric slide block 3 drives the sliding block 4, the connecting frame 5, the cylinder 6, the electric suction cup 7 and the sucked material to be processed to the conveying equipment 71 with insufficient supply, and then closes the electric slide block 3, and then closes the electric suction cup 7, so that the sucked material to be processed moves to the conveying equipment 71 with insufficient supply, and the electric suction cup 7 at the insufficient supply location is driven to pick up the material at the conveying equipment 71 with sufficient supply, and puts it at the conveying equipment 71 with insufficient supply, so as to make full use of the waiting time for processing and improve the loading efficiency.

[0038] When the electric slider 3 drives the sliding block 4, the connecting frame 5, the cylinder 6, the electric suction cup 7 and the sucked material to be processed to move and reset, the inclined frame 94 will contact the top block 95. Under the action of the top block 95, the inclined frame 94 will move. The movement of the inclined frame 94 will push the two rack frames 92 to move away from each other, the reset spring 93 will be compressed, and the movement of the rack frame 92 will push the lower parts of the two swing clamps 96 to swing towards each other. The two swing clamps 96 drive the two clamps 97 to move toward the middle and touch the two side surfaces of the material to be processed. The operator closes the electric suction cup 7, and the two clamps 97 will clamp the material to be processed. Under the action of the torsion spring 98, the two clamps 97 can adaptively fit the side surfaces of the material to be processed, and as the two clamps 97 move toward the middle, two of the side surfaces of the material to be processed can be moved. The material to be processed is corrected. After the correction, the operator starts the electric suction cup 7 to suck the material to be processed again. When the inclined frame 94 is separated from the top block 95, under the elastic force of the reset spring 93, the rack frame 92 will move in the direction of approaching each other, and the rack frame 92 will drive the lower parts of the two swing clamps 96 to move in the direction of moving away from each other. When the two rack frames 92 are reset, the two swing clamps 96 and the clamping plate 97 are also reset; the material to be processed is corrected by the two swing clamps 96 and the clamping plate 97, so that the material to be processed sucked by the electric suction cup 7 can be made more orderly, and the material to be processed put down after transfer is also more orderly, and the time for transferring the material to be processed is fully utilized to correct the material to be processed. The material to be processed does not need to be corrected before being adsorbed, which can improve the efficiency of clamping the material to be processed, and thus improve the efficiency of transferring the material to be processed.

[0039] Example 2: Based on Example 1, Figure 12 As shown, it also includes a secondary adjustment mechanism, which is arranged on the ladder frame 91. The secondary adjustment mechanism is used to further adjust the material to be processed. A column gear 101 is rotatably installed in the middle of the top of the ladder frame 91, and the column gear 101 is engaged with the rack frame 92. Triangular slides 102 are slidably installed on both sides of the ladder frame 91. A driving rack 103 is fixed on one side of the two triangular slides 102 close to each other. The two driving racks 103 are staggered and the two driving racks 103 are engaged with the column gear 101. The lower part of the triangular slide 102 is slidably connected with an adjustment plate 104. A guide groove 105 is opened at the lower part of the ladder frame 91. The upper part of the adjustment plate 104 is located in the guide groove 105, and the adjustment plate 104 will move along the path of the guide groove 105 itself.

[0040] When the two racks 92 move in the direction away from each other, the two racks 92 will drive the column gears 101 on both sides to rotate. The rotation of the column gear 101 will drive the two driving racks 103 to move in the direction of approaching each other. The two driving racks 103 drive the two triangular slides 102 to move along the trapezoidal frame 91 in the direction of approaching each other. The two triangular slides 102 drive the adjustment plates 104 to move in the direction of approaching each other. The adjustment plates 104 move along the guide grooves 105 in the direction of approaching each other. Under the action of the guide grooves 105, the adjustment plates 104 move downward while moving in the direction of approaching each other. When the adjustment plates 104 contact the material to be processed, the other two sides of the material to be processed can be corrected. When the two racks 92 move in the direction away from each other, the two triangular slides 102 drive the two triangular slides 104 to move in the direction of approaching each other. The ... Under the action of the two triangular slides 105, the two triangular slides 102 drive the two triangular slides 104 to move in When 92 moves in the direction of approaching each other, the two rack racks 92 will drive the column gears 101 on both sides to rotate in the opposite direction. The reverse rotation of the column gear 101 will drive the two driving racks 103 to move in the direction of moving away from each other. The two driving racks 103 drive the two triangular slides 102 to move along the trapezoidal rack 91 in the direction of moving away from each other. The two triangular slides 102 drive the adjustment plates 104 to move in the direction of moving away from each other. The adjustment plates 104 move along the guide grooves 105 in the direction of moving away from each other. Under the action of the guide grooves 105, the adjustment plates 104 move in the direction of moving away from each other while resetting upwards. Under the correction action of the adjustment plates 104, the materials to be processed can be further corrected, thereby further improving the efficiency of transferring the materials to be processed.

[0041] Example 3: Based on Example 2, Figures 8-13 As shown, a leveling mechanism is also included, which is arranged on the connecting frame 5. A lifting frame 111 is welded on the triangular slide 102, and lifting frames 112 are slidingly arranged on both sides of the lower part of the connecting frame 5. Two vertical springs 113 are connected between each of the lifting frames 112 and the bottom of the connecting frame 5, and the lifting frame 111 is in contact with the lifting frame 112.

[0042] The regulating plates 104 further include balls 12 , and a plurality of balls 12 are provided on the sides of the two regulating plates 104 that are close to each other.

[0043] When the two triangular slides 102 move toward each other, the two triangular slides 102 will drive the ejecting frames 111 to move toward each other, and the two ejecting frames 111 will drive the ejecting frame 112 to move downward, and the vertical spring 113 will be stretched. The ejecting frame 112 moves downward to correct the material to be processed in the vertical direction. When the material to be processed moves downward, the material to be processed will push the splint 97 to expand outward, and the torsion spring 98 will twist accordingly, which can reduce the friction between the material to be processed and the splint 97, thereby reducing the possible existence of the material to be processed in the correction process. In order to reduce the chance of surface wear or damage, after the material to be processed is corrected, under the action of the torsion spring 98, the splint 97 can still fit tightly with two side surfaces of the material to be processed; when the two triangular slides 102 move away from each other, the two triangular slides 102 will drive the ejecting frames 111 to move away from each other, and under the action of the vertical springs 113, the two ejecting frames 111 will drive the ejecting frames 112 to reset upwards. Under the action of the ejecting frames 112, the material to be processed can be further corrected, and the efficiency of transferring the material to be processed can be further improved.

[0044] When the lifting rack 112 pushes the material to be processed to correct it, the side of the material to be processed will contact the ball 12. Under the guidance of the ball 12, the material to be processed can move more smoothly, which can increase the speed of correcting the material to be processed, avoid wear on the surface of the material to be processed, and further improve the efficiency of transferring the material to be processed.
