Description

Technical Field

[0001] The invention relates to the technical field of light industrial manufacturing, in particular to an automatic stacking and collecting device for plastic cups. Background Art

[0002] The automatic stacking and collection device for plastic cups is a highly automated production equipment designed to achieve a fully automated process from injection molding to stacking and collection of plastic cups. Through precise mechanical design and intelligent control systems, the device can automatically use claws or other gripping mechanisms to accurately remove plastic cups from the mold after the injection molding machine completes the cup molding. The device will then smoothly transport the removed cups to the designated stacking area according to the preset program and path. The entire process does not require excessive human intervention, greatly improving production efficiency and reducing labor intensity, while also ensuring product consistency and stacking neatness.

[0003] In the existing automatic stacking and collection technology for plastic cups, after the plastic cups complete the injection molding process, they are usually clamped by a clamp from one end of the cup so as to be removed from the mold and transported to the designated stacking position. This method of clamping from one end has obvious limitations in actual operation. Specifically, when the clamp clamps one end of the plastic cup for transportation, it can only align the other end of the cup with the stacked cup group to complete the stacking action. This stacking method limits the flexibility of operation and the efficiency of stacking. Because the clamping point of the clamp is fixed, the stacking direction of the cup is also relatively fixed, and flexible stacking at multiple angles or in all directions cannot be achieved. In addition, clamping from one end may also cause uneven force on the cup during transportation, increasing the risk of damage or deformation of the cup, thereby affecting the neatness of the stacking and the final product quality. To this end, we propose an automatic stacking and collection device for plastic cups. Summary of the Invention

DETAILED DESCRIPTION

[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] See also Figure 1-Figure 4 The present invention provides a technical solution: an automatic stacking and collecting device for plastic cups, comprising a base plate 1 and six plastic cups 11, an injection molding mechanism 3 for producing the plastic cups 11 is provided at one side of the upper end of the base plate 1, a first displacement mechanism 2 for driving the injection molding mechanism 3 to move horizontally is provided between the base plate 1 and the injection molding mechanism 3, a collecting mechanism 4 for stacking and collecting the plastic cups 11 is provided at the other side of the upper end of the base plate 1, six clamping mechanisms 10 for clamping the plastic cups 11 are provided at the center of the upper end of the base plate 1, and protective devices for protecting the six clamping mechanisms 10 are provided on the outside of the six clamping mechanisms 10. A protective mechanism 8 is provided, and a driving mechanism 9 is provided at the lower end of the protective mechanism 8 for driving the six clamping mechanisms 10 to operate. A flipping mechanism 7 is provided on one side of the protective mechanism 8 for driving the protective mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10 to complete the flipping movement. A second displacement mechanism 6 is provided at the lower end of the flipping mechanism 7 for driving the flipping mechanism 7, the protective mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10 to move horizontally. A lifting mechanism 5 is provided between the substrate 1 and the second displacement mechanism 6 for driving the second displacement mechanism 6, the flipping mechanism 7, the protective mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10 to rise and fall vertically.

[0035] Furthermore, the injection molding mechanism 3 produces a plastic water cup 11 on one side of the substrate 1, and realizes horizontal movement through the first displacement mechanism 2 so as to deliver the produced water cup to the designated position. Then, the six clamping mechanisms 10, driven by the driving mechanism 9 and protected by the protection mechanism 8, accurately clamp the plastic water cup 11 produced by the injection molding mechanism 3. After completing the clamping of multiple plastic water cups 11, the second displacement mechanism 6, the flipping mechanism 7, the protection mechanism 8 and the six clamping mechanisms 10 will rotate ninety degrees to one side. Then, the flipping mechanism 7 is started, driving the protection mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10 to rotate ninety degrees to one side. The holding mechanism 10 completes the flipping movement together, flips the clamped water cup 180 degrees, and then rotates and transports it to the collection direction. At this time, the second displacement mechanism 6 starts to work, driving the flipping mechanism 7 and its auxiliary mechanisms to move horizontally, and move the water cup to the top of the collection mechanism 4. Finally, under the drive of the jacking mechanism 5, the second displacement mechanism 6, the flipping mechanism 7, the protection mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10 are vertically lowered as a whole, releasing the water cup into the collection mechanism 4, completing the stacked cup collection. During the whole process, various mechanisms work together to realize the automation process of plastic water cups 11 from production to collection.

[0036] In the preferred technical solution of this embodiment, please refer to Figure 5-Figure 7 The first displacement mechanism 2 includes a first base plate 201, and the upper end of the first base plate 201 is fixedly connected to the first mounting blocks 202 on both sides. The two first mounting blocks 202 are rotatably connected with a first screw rod 203 through a bearing. The two first mounting blocks 202 are fixedly connected to the optical axis 204 on both sides. The outer side of the first screw rod 203 is threadedly sleeved with a first slider 205, and the outer sides of the two optical axes 204 are arranged with two sliding sleeves 206. The four sliding sleeves 206 and the upper ends of the first slider 205 are fixedly connected to a first support seat 207. The inside of the first support seat 207 is fixedly sleeved with a first electric push rod 208 at four opposite corners. One side of one of the first mounting blocks 202 is fixedly connected to a first motor 209, and the output end of the first motor 209 is fixedly connected to one end of the first screw rod 203. The injection molding mechanism 3 includes four lifting hydraulic rods 301 and a lower mold base 302. The four jacking hydraulic rods 301 are arranged in a rectangular shape and fixedly connected to At the two ends on one side of the center of the upper end of the substrate 1, the lower mold base 302 is fixedly connected to the output ends of the four first electric push rods 208 at the upper end, and the upper end of the lower mold base 302 is fixedly connected to a plurality of injection blocks 303 in a rectangular arrangement. The output ends of the four lifting hydraulic rods 301 at the upper end are fixedly connected to ear pieces 304, and an upper mold cavity 305 is fixedly connected between the two ear pieces 304 on one side and the two ear pieces 304 on the other side. A plurality of plastic water cups 11 are respectively sleeved on the outside of the plurality of injection blocks 303, and the collecting mechanism 4 includes four second electric push rods 401 and a support plate 402. The four second electric push rods 401 are fixedly connected in a rectangular arrangement on the side of the upper end of the substrate 1 away from the four lifting hydraulic rods 301, and the interior of the support plate 402 is fixedly sleeved with a plurality of collecting sleeves 403 in a rectangular arrangement, and the lower ends of the four collecting sleeves 403 near the four diagonal corners of the support plate 402 are respectively fixedly connected to the four output ends at the upper part of the four second electric push rods 401.

[0037] Furthermore, the first displacement mechanism 2 drives the first screw rod 203 to rotate through the first motor 209 inside it. Since the first screw rod 203 is threadedly sleeved with the first slider 205, and the first slider 205 slides on the optical axis 204 through the sliding sleeve 206 at the same time, the first slider 205 will move horizontally along the axial direction of the first screw rod 203. This movement drives the first support seat 207 and the four first electric push rods 208 thereon to move together, thereby realizing the horizontal movement of the injection molding mechanism 3. In the injection molding mechanism 3, the lower mold base 302 is fixed by the output ends of the four first electric push rods 208. The injection block 303 at the upper end of the lower mold base 302 is used for injection molding of the plastic water cup 11. When the injection molding mechanism 3 moves to the specified position, the four lifting hydraulic rods 301 start working, and their output ends push the ear piece 304 and the upper mold cavity 305 It moves downward and cooperates with the lower mold base 302 and the injection block 303 to complete the injection molding process. After the injection molding is completed, the first displacement mechanism 2 drives the injection molding mechanism 3 to move again. At the same time, the four first electric push rods 208 may perform lifting operations to facilitate demolding between the plastic water cup 11 and the upper mold cavity 305. At this time, the clamping mechanism 10 and other subsequent mechanisms start to work. Through the coordinated action of the driving mechanism 9 and the flipping mechanism 7, the injected plastic water cup 11 is clamped and flipped and then transported to the top of the collection mechanism 4. In the collection mechanism 4, the four second electric push rods 401 collect the stacked plastic water cups 11 through the support plate 402 and the collection sleeve 403. When the plastic water cup 11 is flipped and moved above the collection mechanism 4, the second electric push rod 401 may perform lifting operations to adjust the height of the collection sleeve 403, thereby facilitating the plastic water cup 11 to fall in and stack.

[0038] In the preferred technical solution of this embodiment, please refer to Figure 8-Figure 9The lifting mechanism 5 includes four support tubes 501, which are fixedly connected to the center of the upper end of the base plate 1. A mounting plate 502 is fixedly connected between the four support tubes 501. Three supporting side plates 503 are fixedly connected in a U-shaped arrangement at the edge of the upper end center of the mounting plate 502. A lower slide rail 504 is fixedly connected to both sides of the upper end center of the mounting plate 502. A slide seat 505 is slidingly sleeved on the outer side of the two lower slide rails 504. The upper ends of the two slide seats 505 are fixedly connected to a connecting block 506. The centers of both sides of the block 506 are rotatably connected with pulleys 507, the centers of the four support tubes 501 are all slidably sleeved with guide columns 508, the upper ends of the four guide columns 508 are fixedly connected with a load-bearing table 509, the center of the lower end of the load-bearing table 509 is fixedly connected with a docking plate 5010, both sides of the docking plate 5010 are fixedly connected with side top plates 5011, and the insides of the two side top plates 5011 are penetrated with inclined slideways 5012, and the two pulleys 507 are respectively slidably sleeved inside the two inclined slideways 5012, and the two pulleys 507 are respectively slidably sleeved inside the two inclined slideways 5012. A support frame 5013 is fixedly connected to one side of the center of the upper end of the mounting plate 502, and a pneumatic push rod 5014 is fixedly connected to one side of the support frame 5013. The output end of the pneumatic push rod 5014 is fixedly connected to the center of one side of the connecting block 506. A first conductive slip ring 5015 is fixedly sleeved on the upper part of the load-bearing table 509. The second displacement mechanism 6 includes a second bottom plate 601, which is fixedly connected to the upper end of the first conductive slip ring 5015. A docking vertical plate 602 is fixedly connected to the center of one side of the second bottom plate 601. A second motor 603 is fixedly connected to the docking vertical plate 602 on the side away from the second base plate 601, and a second mounting block 604 is fixedly connected to both sides of the upper center of the second base plate 601. A second screw rod 605 is rotatably sleeved between the two second mounting blocks 604 through a bearing, and a first guide rail 606 is fixedly connected to both sides of the upper center of the second base plate 601. A second slider 607 is threadedly sleeved on the outer side of the second screw rod 605, and a first guide block 608 is slidably sleeved on the outer sides of the two first guide rails 606.

[0039] Furthermore, in the lifting mechanism 5, the four support tubes 501 provide stable support for the entire mechanism. When the pneumatic push rod 5014 is working, its output end pushes one side of the connecting block 506. Since the pulleys 507 are rotatably connected to the centers of both sides of the connecting block 506, and the pulleys 507 are slidably sleeved in the inclined slideways 5012 inside the side top plates 5011, the connecting block 506 will move along the direction of the inclined slideways 5012 and drive the slide 505 to slide on the lower rail 504. This movement is achieved through the connection between the connecting block 506 and the load-bearing table plate 509, so that the load-bearing table plate 509 and the guide column 508 thereon slide up or down inside the support tube 501, thereby realizing the vertical lifting function. At the same time, the first conductive slip ring 5015 fixedly sleeved inside the load-bearing table plate 509 provides electrical connection for subsequent mechanisms such as the second displacement mechanism 6, ensuring the stability of the entire device. The electrical system is stable and reliable. In the second displacement mechanism 6, the second base plate 601 is fixedly connected to the upper end of the first conductive slip ring 5015, so that the second displacement mechanism 6 can rise and fall with the lifting mechanism 5. The second motor 603 drives the second screw rod 605 to rotate, so that the second slider 607 slides on the second screw rod 605, and drives the first guide block 608 to slide on the first guide rail 606, thereby realizing the horizontal movement function.

[0041] Further, in the turnover mechanism 7, the third motor 705 drives the driving bevel gear 706 to rotate, and since the transmission bevel gear 7011 and the driving bevel gear 706 are in gear mesh transmission, the driving shaft 709 rotates, and then, since the driving bevel gear 7010 and the transmission bevel gear 708 are also in gear mesh transmission, the transmission shaft 704 rotates, which drives the two synchronous shafts 7015 to rotate in the same direction through the transmission of the driving sprocket 7017, the transmission sprocket 7018 and the chain 7019, and since the first limiting block 7014 and the second limiting block 7016 abut each other, the stable rotation of the strip-shaped support plate 7013 and the synchronous shaft 7015 is ensured, and the 180-degree forward and reverse rotation of the two synchronous shafts 7015 in the two strip-shaped support plates 7013 is effectively ensured, and in the protection mechanism 8, the fixed frame 801 is connected with the turnover mechanism 7 through the two synchronous shafts 7015, so that when the synchronous shaft 7015 rotates, the fixed frame 801 also rotates, and in the fixed frame 801, the transmission column 809 is rotatably sleeved between the top cover plate 807 and the support bottom plate 802 through a bearing, and the transmission spur gear 8010 is fixedly sleeved at the outer center of the transmission column 809, so that when the transmission column 809 rotates, the double-sided rack 8011 moves horizontally under the guidance of the movable groove 8012 and the positioning strip 804, so that the opening and closing movement of the clamping mechanism 10 in the protection mechanism 8 is realized, and in the driving mechanism 9, the electric telescopic rod 901 is connected with the power supply through the second conductive slip ring 7020, so that when the electric telescopic rod 901 extends and retracts, the driving rack 905 slides in the guide sleeve 902, and since the driving rack 905 and the driving spur gear 903 are in gear transmission, when the driving rack 905 moves horizontally, the transmission column 809 and the transmission spur gear 8010 rotate, and then the opening and closing of the clamping mechanism 10 is realized through the transmission of the double-sided rack 8011, and at the same time, the sliding of the guide strip 906 in the guide groove 904 ensures the stable movement of the driving rack 905, and through the cooperation of the turnover mechanism 7, the protection mechanism 8 and the driving mechanism 9, the turnover movement of the plastic water cup 11 in the collection process is realized, which provides key support for the entire automation process.

[0042] In the preferred technical solution of the embodiment, please refer to Figure 15The clamping mechanism 10 includes a bottom ring 1001 and a top ring 1002. The bottom ring 1001 is fixedly sleeved inside the lower mounting hole 803, and the top ring 1002 is fixedly sleeved inside the upper mounting hole 808. The center of the upper end of the bottom ring 1001 is fixedly connected to the limit ring 1003 near the edge. Five positioning pins 1004 are arranged in a ring and fixedly connected to the center of the top ring 1002 near the edge. The lower ends of the five positioning pins 1004 are vertically fixedly connected to the upper end of the bottom ring 1001. A driving ring 1005 is provided on the outer side of the positioning pin 1004, and a clamping jaw 1006 is provided on the outer side of each of the five positioning pins 1004. A sliding column 1007 is fixedly connected to the upper end of the five clamping jaws 1006 on one side. Five opening and closing grooves 1008 are arranged in a ring and penetrate through the center of the driving ring 1005 near the edge. The five opening and closing grooves 1008 are slidably sleeved inside the five sliding columns 1007. An arc-shaped rack 1009 is fixedly connected to one side of the driving ring 1005.

[0043] Furthermore, the design of the clamping mechanism 10 is similar to the opening and closing of the aperture lens of a camera, and the opening and closing action of the clamping jaw 1006 is realized by the rotation of the driving ring 1005. Specifically, the bottom ring 1001 is fixedly sleeved inside the lower mounting hole 803, and the top ring 1002 is fixedly sleeved inside the upper mounting hole 808. The two together constitute the frame of the clamping mechanism 10. The limit ring 1003 is fixed to the upper end of the bottom ring 1001, and is used to limit the opening and closing range of the driving ring 1005 and the clamping jaw 1006. Five positioning pins 1004 are vertically connected between the bottom ring 1001 and the top ring 1002, providing a fulcrum for the rotation of the clamping jaw 1006. The clamping jaw 1006 is rotatably sleeved on the outside of the positioning pins 1004 and can open and close around the positioning pins 1004. The sliding column 1007 is fixed to the upper end of the clamping jaw 1006, and is used to open and close with the inside of the driving ring 1005. The closing groove 1008 is in sliding engagement. When the drive ring 1005 rotates, the opening and closing groove 1008 will slide along the sliding column 1007. Due to the shape and distribution of the opening and closing groove 1008, the rotation of the drive ring 1005 will drive the clamping jaw 1006 to open and close around the positioning pin 1004. Specifically, when the drive ring 1005 rotates in one direction, the opening and closing groove 1008 will push the sliding column 1007 and the clamping jaw 1006 to open and close together, thereby realizing the opening of the clamping jaw 1006. Conversely, when the drive ring 1005 rotates in the other direction, the opening and closing groove 1008 will pull the sliding column 1007 and the clamping jaw 1006 to merge together, thereby realizing the closing of the clamping jaw 1006. The arc-shaped rack 1009 is fixed on one side of the drive ring 1005, and is used to complete the meshing transmission with the tooth surface on the other side of the double-sided rack 8011 to realize the rotation of the drive ring 1005.

[0044] In the preferred technical solution of this embodiment, please refer to Figure 15The two double-sided racks 8011 are meshed with the three arc-shaped racks 1009 on one side and the three arc-shaped racks 1009 on the other side at the sides away from each other for transmission.

[0045] Furthermore, when the transmission column 809 and the transmission spur gear 8010 inside the protection mechanism 8 begin to rotate, due to the meshing transmission between the double-sided rack 8011 and the transmission spur gear 8010, the double-sided rack 8011 will move horizontally under the guidance of the movable groove 8012 and the positioning bar 804. At this time, the sides of the double-sided rack 8011 that are away from each other respectively form a meshing transmission with the three arcuate racks 1009 on one side and the three arcuate racks 1009 on the other side. When the double-sided rack 8011 moves horizontally to both sides, its teeth will mesh with the teeth of the three arcuate racks 1009 on one side, thereby driving the three arcuate racks 1009 on the corresponding side to rotate. Since the arcuate rack 1009 is fixed on the drive ring 1005, the drive ring 1005 will also rotate accordingly.
