Description

Technical Field

[0001] The invention relates to the technical field of light industry 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 grippers or other gripping mechanisms to accurately remove plastic cups from the mold after the injection molding machine completes the cup molding. Subsequently, the device will 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, which greatly improves production efficiency and reduces 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 have completed the injection molding process, they are usually clamped from one end of the cups by a clamping claw so as to be taken out of the mold and transported to a designated stacking position. This method of clamping from one end has obvious limitations in actual operation. Specifically, when the clamping claw clamps one end of the plastic cup for transportation, it can only align the other end of the cup with the stacked cup group for sleeve installation to complete the stacking action. This stacking method limits the flexibility of operation and the efficiency of stacking. Because the clamping point of the clamping claw is fixed, the stacking direction of the cups 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 cups during transportation, increasing the risk of damage or deformation of the cups, thereby affecting the neatness of the stacking and the final product quality. For this reason, we propose an automatic stacking and collection device for plastic cups. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 4 The present invention provides a technical solution: an automatic stacking and collecting device for plastic cups, comprising a substrate 1 and six plastic cups 11, an injection molding mechanism 3 for producing the plastic cups 11 is arranged at one side of the upper end of the substrate 1, a first displacement mechanism 2 for driving the injection molding mechanism 3 to move horizontally is arranged between the substrate 1 and the injection molding mechanism 3, a collecting mechanism 4 for collecting the plastic cups 11 is arranged at the other side of the upper end of the substrate 1, six clamping mechanisms 10 for clamping the plastic cups 11 are arranged at the center of the upper end of the substrate 1, and protective devices for protecting the six clamping mechanisms 10 are arranged on the outside of the six clamping mechanisms 10. A protection mechanism 8 is provided, and a driving mechanism 9 for driving the six clamping mechanisms 10 to operate is arranged at the lower end of the protection mechanism 8. A flipping mechanism 7 for driving the protection mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10 to complete the flipping movement is arranged on one side of the protection mechanism 8.

A lifting mechanism 5 for driving the second displacement mechanism 6, the flipping mechanism 7, the protection mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10 to lift vertically is arranged between the substrate 1 and the second displacement mechanism 6.

[0020] 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 specified position. Then, the six clamping mechanisms 10, under the drive of 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, and then the flipping mechanism 7 will start, driving the protection mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10 to move to the designated position. The holding mechanism 10 completes the flipping movement together, flips the clamped water cup 180 degrees and then rotates 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 moves the water cup to the top of the collecting mechanism 4. Finally, driven by 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 descended as a whole, and the water cup is released into the collecting mechanism 4 to complete the stacked cup collection. During the whole process, various mechanisms work together to realize the automated process of plastic water cups 11 from production to collection.

[0021] In the preferred technical solution of this embodiment, please refer to Figure 5-Figure 7The first displacement mechanism 2 includes a first base plate 201, the upper end of the first base plate 201 is fixedly connected with a first mounting block 202 at both sides, a first screw rod 203 is rotatably connected between the two first mounting blocks 202 through a bearing, an optical axis 204 is fixedly connected between the two first mounting blocks 202 at both sides, a first slider 205 is threadedly sleeved on the outer side of the first screw rod 203, two sliding sleeves 206 are arranged and slidably sleeved on the outer sides of the two optical axes 204, a first support seat 207 is fixedly connected to the upper ends of the four sliding sleeves 206 and the first slider 205, and a first electric push rod 208 is fixedly sleeved at four diagonal positions inside the first support seat 207, one side of one of the first mounting blocks 202 is fixedly connected with 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, and the injection molding mechanism 3 includes four lifting hydraulic rods 301 and a lower mold base 302, and the four lifting hydraulic rods 301 are arranged in a rectangular shape and fixedly connected to At both 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 top, the upper end of the lower mold base 302 is arranged in a rectangular shape and fixedly connected to a plurality of injection blocks 303, the output ends of the four lifting hydraulic rods 301 at the top are all fixedly connected to ear pieces 304, 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, the collecting mechanism 4 includes four second electric push rods 401 and a supporting plate 402, the four second electric push rods 401 are arranged in a rectangular shape and fixedly connected to a side of the upper end of the substrate 1 away from the four lifting hydraulic rods 301, the interior of the supporting plate 402 is arranged in a rectangular shape and fixedly sleeved with a plurality of collecting sleeves 403, the lower ends of the four collecting sleeves 403 at the four diagonals near the supporting plate 402 are respectively fixedly connected to the four output ends at the top of the four second electric push rods 401.

[0022] 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 and the first slider 205 are threadedly sleeved, and the first slider 205 slides on the optical axis 204 through the 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 seat 302 is fixed by the output ends of the four first electric push rods 208, and the injection block 303 at the upper end of the lower mold seat 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 to work, 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 a lifting operation to facilitate the 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 collecting mechanism 4. In the collecting mechanism 4, the four second electric push rods 401 collect the stacked plastic water cups 11 through the support plate 402 and the collecting sleeve 403. When the plastic water cup 11 is flipped and moved to the top of the collecting mechanism 4, the second electric push rods 401 may perform a lifting operation to adjust the height of the collecting sleeve 403, thereby facilitating the plastic water cup 11 to fall in and stack.

[0023] 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. Lower slide rails 504 are fixedly connected at both sides of the upper end center of the mounting plate 502. Slide seats 505 are slidably sleeved on the outer sides of the two lower slide rails 504. The upper ends of the two slide seats 505 are fixedly connected with connecting blocks 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 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 slidably sleeved inside the two inclined slideways 5012, respectively, A support frame 5013 is fixedly connected to one side of the center of the upper end of the mounting plate 502, a pneumatic push rod 5014 is fixedly connected to one side of the support frame 5013, an 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 at the upper part of the load-bearing table 509, the second displacement mechanism 6 includes a second bottom plate 601, the second bottom plate 601 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 at one side away from the second base plate 601, and second mounting blocks 604 are fixedly connected at 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 via a bearing, and a first guide rail 606 is fixedly connected at 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 first guide blocks 608 are slidably sleeved on the outer sides of the two first guide rails 606.

[0024] 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 at the centers of both sides of the connecting block 506, and the pulleys 507 are slidably sleeved in the inclined slideway 5012 inside the side top plate 5011, the connecting block 506 will move along the direction of the inclined slideway 5012 and drive the slide seat 505 to slide on the lower slide 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 function of vertical lifting. 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 rise and fall of the lifting mechanism 5.

This movement is achieved through the connection between the second displacement mechanism 6 and the flipping mechanism 7, the protection mechanism 8, the driving mechanism 9 and the six clamping mechanisms 10, so that these mechanisms can move horizontally together to complete the collection task of the plastic water cup 11. In summary, the lifting mechanism 5 and the second displacement mechanism 6 work together to realize the vertical lifting and horizontal movement functions in the collection process of the plastic water cup 11, providing key support for the entire automation process.

Two chains 7019 are sleeved on the outer sides of the driving sprocket 7017 and the transmission sprocket 7018 on one side and on the outer sides of the driving sprocket 7017 and the transmission sprocket 7018 on the other side. A second conductive slip ring 7020 is fixedly connected to the side of the strip support plate 7013 away from the transmission sprocket 7018. The passive rotating end of the second conductive slip ring 7020 is fixedly connected to a designated synchronous shaft 7015. The protection mechanism 8 includes a fixed frame 801, which is fixedly connected between the two synchronous shafts 7015. A support base plate 802 is fixedly sleeved at the lower part of the fixed frame 801.Six lower mounting holes 803 are arranged in a rectangular pattern on both sides of the inner part of the support bottom plate 802, positioning strips 804 are fixedly connected at both sides of the center of the upper end of the support bottom plate 802, a positioning layer 805 is fixedly sleeved at the inner center of the fixed frame 801, a positioning hole 806 is penetrated at the inner center of the positioning layer 805, a top cover plate 807 is fixedly sleeved at the upper part of the inner part of the fixed frame 801, six upper mounting holes 808 are fixedly connected in a rectangular pattern on both sides of the inner center of the top cover plate 807, a transmission column 809 is rotatably sleeved between the top cover plate 807 and the inner center of the support bottom plate 802 through a bearing, a transmission spur gear 8010 is fixedly sleeved at the outer center of the transmission column 809, double-sided racks 8011 are arranged at both sides of the center between the top cover plate 807 and the support bottom plate 802, and movable grooves 8012 are penetrated at the inner center of the double-sided rack 8011, and the two movable grooves 8012 are respectively The two double-sided racks 8011 are respectively slidably sleeved outside the two positioning bars 804, and the side where the two double-sided racks 8011 are close to each other is meshed with the transmission spur gear 8010. The driving mechanism 9 includes an electric telescopic rod 901, a guide sleeve 902 and a driving spur gear 903. The electric telescopic rod 901 and the guide sleeve 902 are fixedly connected to one side of the lower end of the supporting base plate 802. The electric telescopic rod 901 is electrically connected to the second conductive slip ring 7020. The driving spur gear 903 is fixedly connected to the center of the lower end of the transmission column 809. A driving rack 905 is slidably sleeved inside the guide sleeve 902. A guide groove 904 is provided on the upper inner wall, the lower inner wall and an inner side wall of the guide sleeve 902. A guide bar 906 is fixedly connected to the upper end, the lower end and one side of the driving rack 905. The three guide bars 906 are respectively slidably sleeved inside the three guide grooves 904, and the driving rack 905 and the driving spur gear 903 are meshed with each other.

[0026] Furthermore, in the flip mechanism 7, the third motor 705 drives the driving bevel gear 706 to rotate. Since the transmission bevel gear 7011 and the driving bevel gear 706 are gear meshing transmission, the driving shaft 709 will rotate accordingly. Then, since the driving bevel gear 7010 and the transmission bevel gear 708 are also gear meshing transmission, the transmission shaft 704 will start to rotate. This rotation is transmitted through the driving sprocket 7017, the transmission sprocket 7018 and the chain 7019, so that the two synchronous shafts 7015 also start to rotate, and the rotation direction is the same. 14 and the second limit block 7016 are mutually abutted, ensuring the stable rotation of the strip support plate 7013 and the synchronization shaft 7015, and effectively ensuring that the two synchronization shafts 7015 complete 180-degree positive and negative rotations inside the two strip support plates 7013 respectively. In the protection mechanism 8, the fixed frame 801 is connected to the flip mechanism 7 through the two synchronization shafts 7015. Therefore, when the synchronization shaft 7015 rotates, the fixed frame 801 will also rotate accordingly. Inside the fixed frame 801, the transmission column 809 is rotatably sleeved between the top cover plate 807 and the support bottom plate 802 through the bearing, and the transmission spur gear The wheel 8010 is fixedly sleeved at the outer center of the transmission column 809. When the transmission column 809 rotates, 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, thereby realizing the opening and closing movement of the clamping mechanism 10 inside the protection mechanism 8. In the driving mechanism 9, the electric telescopic rod 901 is connected to the power supply through the second conductive slip ring 7020. Therefore, when the electric telescopic rod 901 is extended or retracted, it will drive the driving rack 905 to slide inside the guide sleeve 902. There is a toothed transmission between the driving rack 905 and the driving spur gear 903. Therefore, when the driving rack 905 moves horizontally, it will drive the transmission column 809 and the transmission spur gear 8010 to rotate, and then through the transmission of the double-sided rack 8011, the opening and closing of the clamping mechanism 10 is realized. At the same time, the sliding of the guide bar 906 in the guide groove 904 ensures the stable movement of the driving rack 905. In summary, the flipping mechanism 7, the protection mechanism 8 and the driving mechanism 9 work together to realize the flipping movement of the plastic water cup 11 during the collection process, providing key support for the entire automation process.

[0027] In the preferred technical solution of this embodiment, please refer to Fig.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 at 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 rotatably sleeved on the outer side of the positioning pin 1004, and clamping claws 1006 are rotatably sleeved on the outer sides of the five positioning pins 1004. A sliding column 1007 is fixedly connected to the upper end of the five clamping claws 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, and an arc-shaped rack 1009 is fixedly connected to one side of the driving ring 1005.

[0028] 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 achieved by rotating 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 opening and closing groove 1008 is slidably matched. 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.

[0029] In the preferred technical solution of this embodiment, please refer to Fig.15The two double-sided racks 8011 are meshed and driven with the three arc-shaped racks 1009 on one side and the three arc-shaped racks 1009 on the other side respectively, on the sides away from each other.

[0030] 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.
