Description

Technical Field

[0001] The invention relates to the technical field of material receiving and packing machine units, in particular to a finished product receiving and conveying device and a material receiving and packing machine unit docking with a three-station thermoforming machine. Background Art

[0002] The finished product receiving and conveying device and the receiving and packing unit for the three-station thermoforming machine are a comprehensive automation system designed to realize the automatic collection, conveying and packing of finished products on the thermoforming machine production line. With the rapid development of industrial automation, traditional manual operations can no longer meet the needs of large-scale and high-efficiency production. Therefore, automated production lines and automated equipment have emerged to improve production efficiency, reduce production costs and ensure the quality of finished products. The finished product receiving and conveying device and the receiving and packing unit for the three-station thermoforming machine are one of the important applications of industrial automation on the thermoforming production line.

[0003] Since the thermoforming machine usually needs to produce and process the finished products in large quantities, when packing finished products of different specifications, it is not convenient for the packing unit to put one end of the finished product in the same plane with the inner wall of one end of the box according to the specifications of the finished product. When the finished product is not aligned with the inner wall of the box, unnecessary gaps will be generated, so that the internal space of the box may not be fully utilized, and the packing personnel may need to spend more time and energy to adjust the placement of the finished products. When the box is moved, it is not convenient to change the moving distance of the box according to the specifications of the finished product, which may cause the packaging space to be inconvenient to optimize according to the actual size of the finished product. Smaller finished products may cause larger gaps in the box, and larger finished products may not be able to fully utilize the space due to the fixed size of the box, thereby affecting the overall space utilization and transportation efficiency. In view of the above problems, it is urgent to carry out innovative design on the original basis. Summary of the invention

[0035] A moving frame 8 is installed at the top of the transmission belt 1, a slide 9 is slid inside the moving frame 8, a visual sensor 10 is installed at the back end of the moving frame 8, a hydraulic cylinder is installed on the surface of the slide 9, a second moving platform 11 is connected to the output end of the hydraulic cylinder, a pneumatic suction cup 12 is installed at the bottom of the second moving platform 11, a placing platform 13 is installed at the side end of the transmission belt 1, a baffle 14 is arranged at the top of the transmission belt 1, a limiting frame 15 is slidably arranged at the top of the placing platform 13, a slide groove is opened at the top of the placing platform 13, a screw rod is rotatably connected inside the slide groove, a first moving plate 16 is slidably connected in the slide groove, the bottom of the first moving plate 16 is meshed with the screw rod, and a second moving plate 17 is arranged at the top of the first moving plate 16;

[0036] The position limiting adjustment mechanism 18 is arranged on the top surface of the placing table 13 and the transmission belt 1, and the position limiting adjustment mechanism 18 is used to adjust the initial position of the box body according to the specifications of the finished product;

[0037] A moving compensation component 19, which is disposed inside the first moving plate 16 and the second moving plate 17, and can compensate for the moving distance of the box during packing according to the specifications of the finished product;

[0038] When packing finished products of different specifications, it is not convenient to place one end of the finished product in the same plane as the inner wall of one end of the box according to the specifications of the finished product, and it is not convenient to make the moving distance of the box follow the changes in the specifications of the finished product when the box is moved. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the bidirectional screw 5 is driven by a motor to rotate, so that the first moving platform 6 moves inside the adjustment frame 4 until the push rod 7 is in the central area of ​​the finished product, and then the push rod 7 is lowered by the cylinder 3, so that the finished product generated by the three-station thermoforming machine falls on the surface of the transmission belt 1. When the finished product passes through the visual sensor 10, the first electric push rod 182 will drive the baffle 14 to move until the middle of the finished product is located at the bottom of the pneumatic suction cup 12 , the baffle 14 will squeeze the first oil tank 183 when it moves, so that the first oil tank 183 is injected into the second oil tank 186. At this time, the second piston rod 187 drives the limit frame 15 to move synchronously, and then the box is placed on the surface of the second movable plate 17. At this time, the screw is rotated to make one end of the box fit with the inner end of the clamping arm 188, and then the finished product is adsorbed by the pneumatic suction cup 12, and then the finished product is moved to the upper end of the box by the second movable platform 11, and then the finished product is dropped into the box by the hydraulic cylinder. When the screw drives the first movable plate 16, the box will squeeze one end of the short arm of the clamping arm 188. At this time, the long arm of the clamping arm 188 will close inward to limit the box, so as to prevent the box from being dislocated, offset or unstable when moving;

[0039] According to the different specifications of the finished product, the extended end of the second electric push rod 193 will extend to different lengths, thereby pushing the push plate 194 to adjust the size of the internal space of the delivery box 192. Then, the push plate 194 will squeeze the compression block 197 during the adjustment, so that it can be extended and retracted inside the extrusion block 196. At this time, the oil inside the oil storage tank 191 will enter the delivery box 192 through the hose. When the screw rotates, the moving plate will move to the next position. The third electric push rod 195 will squeeze the oil inside the delivery box 192 to the oil pipe 198 through the compression block 197 and the extrusion block 196. When the third electric push rod 195 contracts, the oil in the oil storage tank 191 will continue to fill the delivery box 192, and the oil in the delivery box 192 can push the third piston rod 199 to extend, thereby driving the second movable plate 17 to move backward. When the screw rotates next time, the third electric push rod 195 will continue to squeeze the oil in the delivery box 192 into the oil pipe 198 through the compression block 197 and the extrusion block 196, so that the box body can compensate for its own moving distance every time it moves, so as to ensure that the moving distance of the box body can be consistent with the size of the finished product;

[0040] As an embodiment of the present invention, the limit adjustment mechanism 18 includes two groups of first slots 181 installed at the top of the transmission belt 1, and also includes two groups of second slots 185 installed at the top of the placement table 13. The inner wall of one group of first slots 181 is installed with a first electric push rod 182, and the extended end of the first electric push rod 182 is connected to the baffle 14. The side of the other group of first slots 181 is installed with a first oil tank 183, and the first oil tank 183 slides inside the first piston rod 184. The end of the first piston rod 184 is installed with a protrusion, and the protrusion slides in the side groove of the other group of first slots 181, and the protrusion is connected to the side of the baffle 14. A second oil tank 186 is installed on the inner wall of a second groove platform 185 near the transmission belt 1 side, a second piston rod 187 is slidably arranged inside the second oil tank 186, an end of the second piston rod 187 is connected to the limit frame 15, a clamp arm 188 is rotatably connected inside the limit frame 15, a hose is connected between the first oil tank 183 and the second oil tank 186, and the limit adjustment mechanism 18 can ensure that when the packing unit packs finished products of different sizes, the ends of the finished products can be in the same plane with the inner wall of one end of the box body, so that the finished products are aligned with the inner wall of the box body, avoiding that the internal space of the box body is not fully utilized;

[0041] As an embodiment of the present invention, there are two groups of clamp arms 188, which are symmetrically distributed inside the limiting frame 15. Torsion springs are installed inside the clamp arms 188. The design of the two groups of symmetrical clamp arms 188 can avoid the problem of misalignment, offset or instability when the box is moved, which causes the finished product to be unable to be accurately loaded into the box. The design of the torsion spring allows the box to automatically reset when the clamp arms 188 are not squeezed.

[0042] As an embodiment of the present invention, the clamp arm 188 is composed of a short arm and a long arm, and the angle between the short arm and the long arm is 90°. The ends of the short arm and the long arm of the clamp arm 188 are rotatably connected with rollers. When the box squeezes the short arm, the long arm can better clamp the box. The design of the roller prevents the clamp arm 188 from causing damage to the surface of the box.

[0043] As an embodiment of the present invention, the mobile compensation component 19 includes an oil storage tank 191 and a conveying box 192 installed on the top surface of the first movable plate 16, a second electric push rod 193 is also installed on the top of the first movable plate 16, a push plate 194 is installed on the protruding end of the second electric push rod 193, and the push plate 194 is slidably connected with the conveying box 192, a third electric push rod 195 is installed on the side end of the first movable plate 16, an extrusion block 196 is installed on the protruding end of the third electric push rod 195, and a compression block 197 is slidingly limited inside the extrusion block 196, and an oil pipe 198 is connected to the end of the conveying box 192 through a connecting pipe, and a third piston rod 199 slides inside the oil pipe 198. The mobile compensation component 19 can ensure that when the box body moves, the moving distance of the box body can change with the specifications of the finished product. When each row of the box body is packed and moved to the next row, the end of the finished product in the next row can be closely fitted with the end of the finished product in the previous row, so that the packing unit can adjust the moving distance of the box body according to the specifications of the finished product;

[0044] As an embodiment of the present invention, the push plate 194 has the same size as the inner wall of the conveying box 192, and the push plate 194 slides horizontally inside the conveying box 192. A spring is installed at one end of the compression block 197, and the other end of the spring is connected to the inner wall of the extrusion block 196. The extrusion block 196 slides longitudinally inside the conveying box 192. The push plate 194 moves inside the conveying box 192 according to the size of the finished product, thereby adjusting the internal space of the conveying box 192, so that the box body can compensate for its own moving distance every time it moves, so as to ensure that the moving distance of the box body can be consistent with the size of the finished product;

[0045] As an embodiment of the present invention, a hose is connected between the oil storage tank 191 and the delivery box 192, a hose is connected between the oil pipe 198 and the oil storage tank 191, and a one-way valve is installed at the end of the connecting pipe and the hose. The one-way valve between the oil storage tank 191 and the delivery box 192 can automatically replenish the oil in the delivery box 192 when the oil in the delivery box 192 is delivered to the oil pipe 198. The installation of the one-way valve at the connecting pipe can prevent the oil in the oil pipe 198 from flowing back into the delivery box 192. The design of the one-way valve between the oil pipe 198 and the oil storage tank 191 can return the oil to the oil storage tank 191 when the first movable plate 16 is reset.

[0046] A controller is installed at the side end of the transmission belt 1. At this time, the controller sends out a first control message, which drives the motor to control the rotation of the bidirectional screw 5. The rotation of the bidirectional screw 5 makes the push rod 7 be located in the central part of the finished product. The controller sends out a second control message to drive the cylinder 3 to operate. At this time, the push rod 7 drops the finished product on the surface of the transmission belt 1. When the finished product passes through the visual sensor 10, the visual sensor 10 transmits the size information of the finished product to the controller. At this time, the controller sends out a third control message to drive the first electric push rod 182 to drive the baffle 14 to move, so that the middle of the finished product is located at the bottom of the pneumatic suction cup 12.

[0047] The controller continues to send the fourth control information, which drives the pneumatic suction cup 12 and the hydraulic cylinder to load the finished products into the box. After each row of finished products in the box is loaded, the controller will send the fifth control information to drive the screw to rotate, so that the box can move forward until the whole box of finished products is packed. When the visual sensor 10 transmits the size information of the finished product to the controller, the controller will generate compensation information, and the compensation information will drive the third electric push rod 195 and the second electric push rod 193 to operate to ensure that the moving distance of the box is consistent with the size of the finished product.

[0048] Working principle: When in use, the motor first drives the bidirectional screw 5 to rotate, so that the first moving platform 6 moves inside the adjustment frame 4 until the push rod 7 is in the central area of ​​the finished product, and then the push rod 7 is lowered by the cylinder 3, so that the finished product generated by the three-station thermoforming machine falls on the surface of the transmission belt 1. When the finished product passes through the visual sensor 10, the first electric push rod 182 will drive the baffle 14 to move until the middle of the finished product is located at the bottom of the pneumatic suction cup 12. The baffle 14 will squeeze the first oil tank 183 when moving, so that the first oil tank 183 is injected into the second oil tank 186. When the second piston rod 187 drives the limiting frame 15 to move synchronously, the box is then placed on the surface of the second movable plate 17. At this time, the screw is rotated to make one end of the box fit with the inner end of the clamping arm 188. The finished product is then adsorbed by the pneumatic suction cup 12, and then the finished product is moved to the upper end of the box by the second movable platform 11. The finished product is then dropped into the box by the hydraulic cylinder. When the screw drives the first movable plate 16, the box will squeeze one end of the short arm of the clamping arm 188. At this time, the long arm of the clamping arm 188 will close inward to limit the box, so as to prevent the box from being dislocated, offset or unstable when moving.

[0049] According to the different specifications of the finished product, the extended end of the second electric push rod 193 will extend to different lengths, thereby pushing the push plate 194 to adjust the size of the internal space of the delivery box 192. Then, the push plate 194 will squeeze the compression block 197 during adjustment to make it expand and contract inside the extrusion block 196. At this time, the oil inside the oil storage tank 191 will enter the delivery box 192 through the hose. When the screw rotates, the moving plate will move to the next position. The third electric push rod 195 will squeeze the oil inside the delivery box 192 into the oil pipe 198 through the compression block 197 and the extrusion block 196. When the third electric push rod 195 contracts, the oil inside the oil storage tank 191 The oil will continue to fill the delivery box 192, and the oil inside the delivery box 192 can push the third piston rod 199 to extend, thereby driving the second movable plate 17 to move backward. When the screw rotates for the next time, the third electric push rod 195 will continue to squeeze the oil inside the delivery box 192 into the oil pipe 198 through the compression block 197 and the extrusion block 196, so that the box can compensate for its own moving distance every time it moves, to ensure that the moving distance of the box can be consistent with the size of the finished product. When the screw drives the first movable platform 6 to move to the initial position, the oil inside the oil pipe 198 will enter the oil storage tank 191 through the hose.
