Description

Technical Field

[0001] The present invention relates to the technical field of equipment for preparing and packaging plastic cups, bowls, lids and plates, and in particular to a quantitative conveying device for layer-by-layer material connection and a conveying and packing unit for containers and lids of various specifications. Background Art

[0002] Disposable plastic tableware for daily use, such as disposable cups, bowls, plates, lids, boxes, and other products, are produced in two main ways in the prior art. The first is injection molding. Although injection molding can fully utilize raw materials without any scraps and saves money, it has the disadvantages of expensive molds, long mold processing and debugging cycles, and the potential loss of market opportunities. In addition, the number and speed of each mold cannot be compared with sheet-type thermoforming cup-making machines. The second is to use sheet-type thermoforming machines to punch out the molds. In this type of production, the product has a solid color and no patterns, which is of relatively low quality. Even if the product is printed on a curved surface, the clarity and texture of the graphics cannot be compared with injection molded labels. Therefore, the applicant of the present invention has developed an in-mold labeling production line to achieve the simultaneous affixing of rich graphic labels while producing and preparing products, greatly improving the product's aesthetics and increasing its added value. However, the traditional cup-making machine requires six movements per mold when connected to a stacking and conveying robot. When in-mold labeling is performed, an in-mold labeling robot needs to be added to the production line. The in-mold labeling robot must first wait for the unloading robot to descend to make room. The in-mold labeling robot then moves horizontally in, descends to place the label, and then rises horizontally to exit. Therefore, even an in-mold labeling robot connected to a traditional flip mold requires nine movements to complete the production of one mold of products. Connecting it to the upper and lower pressing thermoforming cup-making machines requires eleven movements to complete the task. The large number of movements makes the efficiency relatively low. Therefore, the use of existing cup-making machines to ensure low investment costs and low mold modification costs, short production cycles, and more conducive to seizing opportunities, increasing product added value, and streamlining production line operations and high work efficiency has become a research hotspot. However, even if the problem of fast and efficient production of in-mold labeling is solved, if there is no technology for efficiently transferring and automatically packing products into boxes, then it will be impossible to package plastic products such as plastic cups, bowls, plates and lids in a box. The stacked materials need to be pushed into the box according to a certain number of strips or rows. For most of the whole stacked cups, bowls, lids and other materials, the materials need to be turned over and adjusted in direction before being stacked and put into the box. Improving the efficiency of automated boxing is also very important for the development of the enterprise and the rapid production of products. However, the boxing machine in the existing technology has a complex structure, many mechanical parts, high equipment cost, and a large equipment footprint. In addition, it cannot realize the function of packing multiple cups, bowls or lids layer by layer, and the stacked cups, bowls and lids are easy to be scattered. Patent document CN 105730764 A discloses a "material packing method." Although this technology can solve the problem of automatically packing materials by layer to a certain extent, it has the following problems: (1) During the process of lifting and unloading the carton, the carton mechanism is heavy and prone to shaking. It also consumes a lot of energy and the equipment is easily damaged and replaced. (2) During the process of lifting and unloading the carton, plastic cups, bowls, plates, or lids already in the carton are easily scattered and fall off.

Compared with the prior art, the present invention has the following advantages:

[0044] (1) The heavy-duty cartons do not move but are raised and lowered by the lighter conveyor platform and the receiving tray. The structure is simpler and the cost is lowered, and the energy consumption is greatly reduced. The conveyor platform is faster than the device that carries the cartons, and the layered packing work is more efficient. It prevents the cartons from shaking, which will cause the products in the cartons to scatter.

Compared with the existing technology, there is no need to add a second lifting and pushing device. The original pushing plate can be used to push the product on the receiving tray forward a little to overcome the problem that the product is blocked on the latch hole and the latch cannot be inserted. The structure is simpler, and the latch lifting cylinder and the latch move with the pushing plate and the latch rises and falls independently, which is fast and the overall structure is more compact and simple.

[0047] The multifunctional container and lid conveying and packing unit of the present invention has the following advantages over the prior art:

[0048] (1) The cartons of the multi-specification material receiving and packing conveyor device do not need to be lifted up and down, but the feeding tray of the layer-by-layer material receiving and quantitative conveyor device lifts and lowers the materials layer by layer. The fixed cartons make the product packing more stable and effective, and can reduce the energy consumption of the equipment and reduce costs.

[0049] (2) The push drive support frame of the conveying platform device is located on one side above the material receiving and delivering platform, and the push support frame of the layer pushing device is located on the other side above the material receiving and delivering platform. With this arrangement, the push drive support frame and the push support frame can be appropriately extended backward according to actual needs without colliding with each other.

[0050] (3) The multifunctional material picking, conveying and stacking robot, material splicing and stacking conveying device, material splicing and transferring conveying robot, single-row whole-strip splicing and lateral conveying device, position-limited material splicing, flipping and translational horizontal quantitative conveying device, layer-by-layer material splicing and quantitative conveying device and multi-specification material splicing and boxing conveying device of the present invention can all convey products with limited position and are applicable to the conveying, stacking and boxing of products of various specifications and shapes.

[0051] (4) The full automation of the material receiving, stacking, conveying and packing of plastic food containers and lids after preparation has been achieved, greatly improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0087] The present invention will be further described with reference to the following examples.

[0088] Example 1

[0089] Referring to the accompanying drawings, the multifunctional container and lid conveying and case packing unit of this embodiment includes a multifunctional material retrieving, conveying, and stacking robot A, a material receiving and stacking conveyor B, a transfer conveying robot C, two single-row, whole-strip stacking lateral conveying devices D, a position-limited, material receiving, flipping, and translating transverse quantitative conveying device E, a layer-by-layer quantitative conveying device G, and a multi-specification material receiving, conveying, and case packing device H. The multifunctional material retrieving, conveying, and stacking robot A, the material receiving and stacking conveyor B, the transfer conveying robot C, the single-row, whole-strip stacking lateral conveying device D, the position-limited, material receiving, flipping, and translating transverse quantitative conveying device E, the layer-by-layer quantitative conveying device G, and the multi-specification material receiving, conveying, and case packing device H are all controlled and operated in coordination by a PLC control system. Among them, the multifunctional material taking, conveying and stacking robot A takes materials from the cup making machine and stacks the materials on one of the receiving trays of the material receiving and stacking conveying device B. The transfer conveying robot C takes materials from the receiving tray of the material receiving and stacking conveying device B and transfers it to the single-row whole-strip stacking lateral conveying device D to stack it into a whole strip. The single-row whole-strip stacking lateral conveying device D conveys multiple strips of materials to the limited material receiving, flipping and translational horizontal quantitative conveying device E. The limited material receiving, flipping and translational horizontal quantitative conveying device E pushes the materials to the layer-by-layer material receiving and quantitative conveying device G. The layer-by-layer material receiving and quantitative conveying device G pushes the materials layer by layer to the cartons of the multi-specification material receiving, conveying and packing device H. The multi-specification material receiving, conveying and packing device H is equipped with cartons. When the materials are put into the cartons, the multi-specification material receiving, conveying and packing device H does not need to be lifted or lowered. The layer-by-layer material receiving and quantitative conveying device G can be lifted or lowered to push the materials into the cartons layer by layer. The cartons of the multi-specification material receiving and packing conveyor device do not need to be raised or lowered, but are pushed layer by layer by the feed tray of the layer-by-layer material receiving and quantitative conveying device. The cartons are fixed, making product packing more stable and effective, and can reduce equipment energy consumption and costs. The multi-functional material picking, conveying and stacking robot A, the material receiving and stacking conveyor device B, the transfer conveying robot C, the two single-row whole-strip overlapping lateral conveying devices D, the limited material receiving, flipping and translational horizontal quantitative conveying device E, the layer-by-layer material receiving and quantitative conveying device G and the multi-specification material receiving, conveying and packing device H are all controlled by a PLC control system and operate in coordination, realizing automated operation and high work efficiency. It should be noted when necessary that the material receiving and stacking conveyor device B, the transfer conveying robot C, and the two single-row whole-strip overlapping lateral conveying devices D of this embodiment can all adopt equipment in the existing technology. Specifically, the material receiving and stacking conveying device B slides to the unloading station after completing the programmed preset number of stacking at the material receiving station. The material receiving station is the position where the material receiving tray of the material receiving and stacking conveying device B receives the material from the multi-functional material picking, conveying and stacking robot A. The unloading station is the position where the material receiving tray of the material receiving and stacking conveying device B transfers the material to the transfer conveying robot C. The material receiving station and the unloading station can be determined according to the actual space size and layout of the factory and production line. Those skilled in the art should be able to clearly understand the concept of the station and the determination method.The material splicing transfer robot C completes the single-row material splicing and transfers the finished product to the single-row whole-line overlapping lateral conveying device D. The single-row whole-line overlapping lateral conveying device D completes the limited material splicing according to the packing length and then transfers the finished product laterally to the limited material splicing, flipping and translational horizontal quantitative conveying device E. The limited material splicing, flipping and translational horizontal quantitative conveying device E operates at the material splicing station and the discharging station. Those skilled in the art should be able to clearly understand the concept of the station and the determination method of the material splicing station and the discharging station. The finished products are pushed in sequence and in fixed quantities to the receiving tray G8 with limit positions on both sides of the quantitative conveying device G for receiving materials by layer. After the receiving tray G8 of the quantitative conveying device G for pushing carton by layer completes receiving materials for one layer, the receiving tray G8 and the finished products are pushed into the carton by layer, and then the empty receiving tray G8 is pulled out and reset to the standby position (the standby position can be determined according to the actual space and layout of the factory and production line). This operation is repeated and conveyed to the multi-specification carton conveying device H to complete the receiving of full boxes. When receiving materials in the carton, the opening of the carton is facing the quantitative conveying device G for receiving materials by layer and the carton is fixed. The receiving tray G8 of the quantitative conveying device G for receiving materials by layer sends the entire tray of products into the carton and then pulls out the empty receiving tray G8.

[0090] In this embodiment, the limited material receiving and flipping horizontal quantitative conveying device includes a flip support seat E1, a cylinder mounting seat E2, a flip driving cylinder E3 and a receiving and unloading conveying plate E4. The flip support seat E1 is provided with a flip support shaft E5, the flip support shaft E5 passes through the cylinder mounting seat E2 and the cylinder mounting seat E2 can rotate around the flip support shaft E5, the flip driving cylinder E3 is installed on the cylinder mounting seat E2, the telescopic rod of the flip driving cylinder E3 is hinged to the bottom of one side of the receiving and unloading conveying plate E4, and the bottom of the other side of the receiving and unloading conveying plate E4 is hinged to the flip support seat E1. When the flip driving cylinder E3 pushes and pulls the receiving and unloading conveying plate E4, the conveying platform can be flipped. Among them, the receiving and unloading conveyor disc E4 is also provided with a packing length limit plate E7 and a length adjustment threaded rod E6. The threaded rod is installed on the receiving and unloading conveyor disc E4 and fixes the packing length limit plate E7. According to actual needs, the length adjustment threaded rod E6 can be manually rotated to adjust the position of the packing length limit plate E7, so as to be suitable for products stacked in different lengths. Since the two ends of the strip products are restricted, the products are prevented from being scattered.

[0091] In order to facilitate the adjustment of the position of the conveying platform, the limited material receiving and flipping horizontal quantitative conveying device of this embodiment is also provided with a rotating connecting plate E8 and a horizontal sliding connecting plate E10. The upper end of the rotating connecting plate E8 is hinged to the flip support seat E1, and the lower end is hinged to the telescopic rod of the flip driving cylinder E3. The rotating connecting plate E8 is provided with a transverse rail E9, and the transverse sliding connecting plate E10 is fixed to the bottom of the receiving and unloading conveying disc E4. The transverse sliding connecting plate E10 is fixed with a slider and a cylinder telescopic rod connecting piece E12. The slider is slid on the transverse rail E9, and the transverse cylinder E19 is installed on the rotating connecting plate E8. The telescopic rod of the transverse cylinder E19 is connected to the cylinder telescopic rod connecting piece E12. When the telescopic rod of the transverse cylinder E19 is extended, the transverse sliding connecting plate E10 is driven to slide along the transverse rail E9 through the cylinder telescopic rod connecting piece E12, and the transverse sliding connecting plate E10 drives the receiving and unloading conveying disc E4 to move to adjust the position of the receiving and unloading conveying disc E4.

[0092] To facilitate the translational loading and unloading of materials by the position-limited, reversible, and transverse quantitative conveyor, this embodiment of the position-limited, reversible, and transverse quantitative conveyor also includes a translation support frame E16, a translation support platform E17, and a translation drive device E18.

The installation method is conventional, and the specific structure and operating principle of translation drive device E18 are not detailed here.

[0093] A quantitative pushing robot is provided on the feeding side of the quantitative conveying device G for layer-by-layer material collection. The quantitative pushing robot includes a quantitative pushing support frame E13, a quantitative pushing drive device and a quantitative pushing plate E15. The quantitative pushing drive device is installed on the quantitative pushing support frame E13 and consists of a quantitative pushing motor E14 and a transmission assembly. The quantitative pushing motor E14 drives the quantitative pushing plate E15 to move through the transmission assembly to push the material. The conveying assembly in this embodiment consists of a synchronous belt and a synchronous wheel with an axis. The quantitative pushing motor E14 and the transmission assembly are conventional technologies, which should be clearly understood and implemented by those skilled in the art. The quantitative pushing plate E15 is connected to the synchronous belt through a connecting piece. When the quantitative pushing motor E14 drives the synchronous belt to rotate, the quantitative pushing plate E15 rotates with the synchronous belt.

[0094] The characteristic of the position-limited material receiving, flipping, translating and horizontal quantitative conveying device E is that after receiving the material, it rotates and translates to the material receiving station. After receiving the material, it rotates, translates and the cylinder moves simultaneously to push the receiving and unloading conveying disc out of the station and translates to the layer-by-layer packing device. The standby quantitative pushing robot pushes the product into the receiving disc of the layer-by-layer material receiving and quantitative conveying device G according to the programmed instructions. After each push, the horizontal cylinder of the position-limited material receiving, flipping, translating and horizontal quantitative conveying device must be reset to facilitate the layer-by-layer material receiving and quantitative conveying device G to complete the action.

[0095] The quantitative conveying device for receiving materials by layer in this embodiment includes a quantitative conveying bracket G1, a layer-by-layer lifting drive device, a conveying platform G7, a material receiving tray G8, a pushing device, a tray unloading gate G9 and a tray unloading gate lifting drive device G10. The tray unloading gate G9 is installed at the discharge port of the quantitative conveying device for receiving materials by layer and is driven to rise and fall by the tray unloading gate lifting drive device G10. The tray unloading gate lifting drive device G10 can be a drive composed of a cylinder, an electric push rod or a motor G2 and a transmission component. As long as it can drive the tray unloading gate G9 to rise and fall, it is within the protection scope of the present invention.

[0096] The layer-by-layer lifting drive device is installed on the quantitative conveying bracket G1 and drives the conveying platform G7 to rise and fall. The layer-by-layer lifting drive device includes a motor G2, a lifting support base G3, a slider, a gear, a rack G4, a guide rail G5, and a lifting connecting plate G6. The motor G2 is installed on the outside of the lifting support base G3. The side of the lifting support base G3 is fixedly connected to a slider. The slider is slidably provided with a guide rail G5. The guide rail G5 is fixedly connected to the rack G4. The rack G4 meshes with a gear mounted on the rotating shaft of the motor G2 for transmission. The lifting support base G3 is installed with a sliding sleeve. The sliding sleeve is slidably provided with a sliding rod. The upper end of the sliding rod, the upper end of the rack G4, and the upper end of the guide rail are all fixedly connected to the bottom of the translation push structure. The lower end of the sliding rod, the lower end of the rack G4, and the lower end of the guide rail are all fixedly connected to the lifting connecting plate G6. The meshing transmission of the rack G4 and the gear can achieve multiple lifting and lowering and any distance lifting. In addition, the meshing transmission effect of the teeth is more stable and has stronger load-bearing capacity.

[0097] Among them, the pushing device includes a translation pushing support structure G11, a translation pushing drive device G12, a translation lifting support platform G13, a lifting drive source G14, a lifting connection structure G15, a push plate G16, a cylinder fixing seat G17, a latch lifting cylinder G18, a latch connecting plate G19 and a latch G20. The translation lifting support platform G13 is slidably arranged on the upper part of the translation pushing support structure G11 through a guide rail and a slider and is driven to translate by the translation pushing drive device G12. The lifting drive source G14 is installed on the translation lifting support The support platform G13 drives the lifting connection structure G15 to rise and fall. The front lower part of the lifting connection structure G15 is fixed with the push plate G16. The back of the lifting connection structure G15 is fixed with the cylinder fixing seat G17. The latch lifting cylinder G18 is installed on the cylinder fixing seat G17 and independently drives the latch connection plate G19 to rise and fall. The latch G20 is fixed on the bottom of the latch connection plate G19. The latch G20 can be inserted into the latch hole G8-1 of the receiving tray G8 so that the receiving tray G8 moves simultaneously with the push plate G16. The receiving tray G8 is slidably arranged on the conveying platform G7. At the same time, the pusher plate G16 of this embodiment can be moved by the translational pushing support structure G11 to the rear of the receiving plate, pushing the products on the receiving tray G8 forward a certain distance so that the products on the receiving tray G8 clear the position of the latch hole G8-1 on the receiving tray G8. This structure can smoothly insert the latch pin G20 into the latch hole G8-1, and there is no need to add a lifting and pushing device specifically to push the products a small distance without affecting normal pushing. The structure is reasonable, the operation is simple and fast, and work efficiency is effectively improved. In this embodiment, the unloading gate lifting drive device G10 is located at the front upper part of the lifting and pushing support structure. The unloading gate lifting drive device G10 drives the unloading gate G9 to rise or fall. The lifting and lowering of the gate plate is used to limit the movement of products during the non-pushing process to prevent the products from falling or scattering.

[0098] During boxing, the method for the layered material quantitative conveying device of the present invention to box the products on the receiving tray is as follows:

[0099] 1. The cartons are in place;

[0100] 2. The conveyor platform of the layer-by-layer quantitative conveyor device descends after the tray is filled with materials.

[0101] 3. The push plate G16 moves back and down, pushing the product on the receiving tray a certain distance to expose the latch hole of the receiving tray;

[0102] 4. The latch lifting cylinder drives the latch down and inserts it into the latch hole of the receiving tray;

[0103] 5. The translational push drive device drives the push plate G16 to push the entire tray of materials into the carton;

[0104] 6. The unloading gate of the layer-by-layer quantitative conveying device descends to block the upper half of the product and then draws it out to form a receiving tray. The unloading gate prevents the material from being drawn out with the receiving tray when it is withdrawn. Correspondingly, the lower gate installed at the carton opening rises to block half of the product.

[0105] 5. Push the drive device to pull out the receiving tray;

[0106] 6. Reset, the conveyor platform drives the receiving tray to rise and receive the material from the conveyor platform device;

[0107] 7. Repeat steps 2 to 6 above until the packing task is completed.

[0110] Example 3

[0111] The main technical solution of this embodiment is basically the same as that of embodiment 1. For features not explained in this embodiment, the explanation in embodiment 1 shall apply and will not be repeated here. In this embodiment, the multifunctional material picking, conveying and stacking robot A includes a primary translation support frame A1, a primary translation drive device A2, a lifting and translation support seat A4, a lifting drive device A3, a lifting and translation support plate A8 and a palm plate A13.

The primary translation drive device A2 is mounted on the primary translation support frame 1 and is composed of a motor, a synchronous wheel and a synchronous belt. The synchronous belt is fixed to the lifting and translation support seat A4 by a clip, a bolt or other connecting parts. When the synchronous belt moves under the drive of the motor, the lifting and translation support seat A4 drives the lifting and translation support plate A8, the lifting drive device A3 and the palm plate A13 and other components to translate simultaneously.

[0112] In this embodiment, a lifting drive device A3 is mounted on a lifting and translating support base A4 and drives a lifting and translating support plate A8 to move upward and downward. Guide rod A7 is affixed to lifting and translating support plate A8, which passes through lifting and translating support base A4 and is connected to lifting plate A6 on top. Furthermore, lifting drive device A3 comprises a motor, a synchronous pulley, and a synchronous belt. The synchronous belt is vertically mounted and connected to lifting plate A6 via clips, bolts, or other connectors. When the synchronous belt moves under the action of the motor, lifting plate A6 rises or falls with the synchronous belt. Simultaneously, lifting plate A6 drives guide rod A7 and lifting and translating support plate A8 upward and downward. It should be noted that lifting drive device A3 can also be replaced with other drive devices, such as a pneumatic cylinder or screw elevator.

[0113] The lifting and translational support plate A8 is mounted with a secondary translational sliding mounting plate A9 via a second sliding pair A19. This second sliding pair A19 comprises a guide rail and a slider. In this embodiment, the slider is fixedly attached to the lifting and translational support plate A8, and the secondary translational sliding mounting plate A9 is fixedly attached with a slide rail, which is slidably connected to the slider. The lifting and translational support plate A8 is mounted with a secondary translational drive device A14, which comprises a motor, a synchronous pulley, and a synchronous belt.

[0114] A palm tray A13, used for removing and unloading cups, is removably mounted to the secondary, translating, sliding mounting plate A9. The palm tray A13 comprises a palm tray support plate A12 and multiple loading and unloading components. The palm tray support plate A12 is removably mounted to the secondary, translating, sliding mounting plate A9, allowing for convenient replacement of different palm trays to meet the needs of conveying materials for different products. The central axis of the palm tray support plate A12 is either parallel or perpendicular to the central axis of the secondary, translating, sliding mounting plate A9. The specific orientation depends on the specific cup production line mode and the selection of the palm tray to be replaced.

[0115] In this embodiment, each set of loading and unloading components includes a suction cup, a connecting rod and an air nozzle. An air duct is provided in the connecting rod, and the suction cup is installed at the lower end of the air duct. The air duct is connected to the positive and negative pressure generating device through the air nozzle and the pipeline. The positive and negative pressure generating device can be an air pump that generates negative pressure or positive pressure.

[0116] Example 4

[0117] The main technical solution of this embodiment is essentially the same as that of embodiment 1. Features not explained in this embodiment are explained in embodiment 1 and will not be further elaborated here. The material splicing and stacking conveyor device B can be configured as an AB unit multi-directional sliding alternating splicing and conveying device or an AB unit telescopic alternating telescopic splicing and unloading device, depending on actual needs.

[0118] When the unit is used for receiving, conveying, and packing white cups, an AB unit multi-directional sliding alternating receiving and conveying device is selected as the receiving and stacking conveyor device B. This unit is equipped with two stacking units, namely Unit A and Unit B, which operate in alternating coordination. Each stacking unit includes a receiving tray B1, a primary drive mechanism, and a secondary drive mechanism. The primary drive mechanism includes a mounting plate B2-1, a primary slider B2-2, a primary guide rail B2-3, a primary drive mechanism B2-4, and a primary support platform B2-5. The receiving tray B1 is removably mounted to the mounting plate B2-1, allowing for easy replacement of different receiving trays 1 to accommodate the stacking of products of different specifications and cup shapes. Among them, the bottom of the mounting plate B2-1 is fixed with a first-level slider B2-2, the first-level slider B2-2 is slidably mounted on the first-level guide rail B2-3, the first-level guide rail B2-3 is fixed to the first-level support platform 2-5, and the mounting plate B2-1 is driven to move in translation by a first-level driving mechanism, wherein the first-level driving device B2-4 can be composed of a motor, a transmission wheel, a transmission shaft and a transmission belt. The connection method of the motor, the transmission wheel, the transmission shaft and the transmission belt is conventional technology and will not be repeated here. It should be noted that the first-level driving device B2-4 can also be set as an electric screw, a cylinder or other equipment that can drive the first-level support plate to move in translation, all of which are within the scope of protection required by the present invention. In this embodiment, the first-level driving device B2-4 is set as a cylinder. The secondary driving mechanism of this embodiment includes a connecting component, a secondary driving device B3-1 and a support frame B3-2. The secondary driving device B3-1 is installed on the support frame B3-2, and the secondary driving device B3-1 drives the first-level support platform B2-5 to move in translation through the connecting component. Among them, the connecting component can be any structure that can realize the connection between the secondary drive device B3-1 and the primary support platform B2-5. The present invention configures the driving source through a plurality of different sliding guide rails, and cleverly uses the common motion space by staggering the telescopic and high and low installation positions, so that the receiving trays B1 of the two sets of stacking units can replace the common receiving station, unloading station and sampling station. At the same time, the two sets of stacking units are arranged side by side to achieve multi-stage telescopic longitudinal translation, so that different equipment groups can be connected. The present invention can replace the receiving tray B1 at any time according to needs, so that it can be applied to products of various specifications and sizes, such as cups, bowls, plates, plates and lids. Among them, different receiving trays 1 can be set for different cup types.

[0119] When the unit is used for in-mold labeling material splicing, conveying and packing, the AB unit telescopic alternating telescopic splicing and unloading device is selected as the material splicing, stacking and conveying device B. The AB unit telescopic alternating telescopic splicing and unloading device includes a bracket B'1 and two splicing units B'3. The splicing unit includes a plurality of material splicing brackets B'3-1, a telescopic support member B'3-7, a telescopic slide rail B'3-6 and a telescopic drive device. The bottom of the material splicing bracket B'3-1 is fixed with a slider B'3-5, the slider B'3-5 is slidably arranged on the telescopic slide rail B'3-6, and the telescopic slide rail B'3-6 is installed on the telescopic support member B'3-7.

[0120] Multiple material receiving brackets B'3-1 of each stacking unit are arranged side by side, and multiple material receiving ports B'3-2 for stacking cup materials are provided on the upper part of the material receiving bracket B'3-1. At the same time, two adjacent material receiving brackets B'3-1 are connected by a clamping ring assembly. The clamping ring assembly includes a clamping ring B'4-1 and a limiting column. One end of the clamping ring B'4-1 is fixed to a material receiving bracket B'3-1, and the other end is provided with a limiting groove. The limiting column is fixed to an adjacent material receiving bracket B'3-1 and passes through the limiting groove of the clamping ring B'4-1. The telescopic drive device drives the side material receiving bracket B'3-1 to move along the direction of the telescopic support member B'3-7. The telescopic drive device includes a synchronous wheel B'3-11, a synchronous belt B'3-12, and a motor B'3-13. The synchronous wheel B'3-11 is mounted on the bracket 1, and the synchronous belt B'3-12 is mounted on the synchronous wheel B'3-11 and parallel to the telescopic support B'3-7. The motor B'3-13 drives the synchronous wheel, which drives the synchronous belt B'3-12 to rotate. The synchronous belt B'3-12 is connected to the material receiving bracket B'3-1 on the side via a connector. The material receiving bracket B'3-1 on the side drives the other material receiving brackets B'3-1 to move via a clamping ring assembly. The connector can be a clip or other shaped plate, and the connection method can be snap, screw, or welding. When the motor B'3-13 is operating, the synchronous belt B'3-12 can rotate. The rotation of the synchronous belt B'3-12 can drive the side material receiving bracket B'3-1 to move. Because multiple material receiving brackets B'3-1 are connected by a clamping ring assembly, the movement of the side material receiving bracket B'3-1 will pull other material receiving brackets B'3-1 to move and achieve a certain distance of expansion. The specific movement distance is determined by the length of the clamping ring limit groove of the clamping ring assembly.

[0121] The two splicing units are the first and second splicing units. The first splicing unit's telescopic supports B'3-7 are driven for translation by a first translation drive B'5. The second splicing unit's telescopic supports B'3-7 are elevated by a lifting drive B'7, which is mounted on a translation support platform B'8, which is driven for translation by a second translation drive B'6. The two splicing units alternately splice materials, improving efficiency.

[0122] It should be noted that the multifunctional unloading robot involved in the multifunctional container and lid conveying and packing unit of the present invention can adopt an existing robot as long as it can realize the function of taking out the product from the cup-making mold and transferring it to the receiving stacking conveying device.

[0123] Example 4

[0124] The main technical solution of this embodiment is basically the same as that of embodiment 1. For features not explained in this embodiment, the explanation in embodiment 1 is adopted and will not be repeated here. In this embodiment, the transfer conveying robot of this embodiment is provided with a supporting fork C1, a material pressing limit plate C2, a material pressing cylinder C3, a staggered driving cylinder C4, a connecting seat C5, a translation lifting support seat C6, a lifting drive device and a translation driving device C8. The front end of the supporting fork is provided with a plurality of material picking forks C1-1; the material pressing cylinder C3 drives the material pressing limit plate C2 to rise or fall; the supporting fork C1 and the material pressing cylinder C3 are installed on the connecting seat C5, and the staggered driving cylinder C4 can drive the supporting fork to move left or right; the lifting drive device is installed on the translation lifting support seat C6 and drives the connecting seat C5 to rise or fall, and the translation lifting support seat C6 is driven to translate by the translation driving device C8, and the translation driving device C8 is composed of a motor, a transmission wheel and a transmission belt. Compared with the existing technical structure, the transfer conveying robot of the present invention is simpler and more reasonable, easy to operate and has a lower cost.

[0125] Among them, in this embodiment, the lifting drive device includes a toothed bar C7-1, a gear C7-2, a transmission shaft C7-3 and a motor C7-4. The lower end of the toothed bar is fixed to the connecting seat, the teeth of the toothed bar are engaged with the gear, the gear is fixed to the transmission shaft, and the transmission shaft is rotatably installed on the translation lifting support seat and driven to rotate by the motor. Such a structure can make the lifting of the connecting seat more stable and can achieve multiple lifting and weighing effects.

[0126] Example 5

[0127] The main technical solution of this embodiment is basically the same as that of embodiment 1. The features not explained in this embodiment adopt the explanation in embodiment 1 and will not be described again here. The multi-specification material receiving, conveying and packing device can be a simple rack on which cartons can be placed, or it can adopt the packing equipment in the prior art. However, in order to realize the full automation of the unit, the multi-specification material receiving, conveying and packing device of this embodiment is configured as a multi-specification material receiving and packing conveying device independently developed by the applicant. Specifically, the multi-specification material receiving and packing conveying device of this embodiment is provided with a diaphragm ring H1-3, a material receiving translation and rotation drive unit H3, a lifting drive device H4, a carton placement unit H1 and a diaphragm ring removal unit H2. The upper frame of the diaphragm ring H1-3 is provided with a magnetic attraction portion H1-31 that can be attracted by a magnetic material. The material of the ring H1-3 of the embodiment can be iron. Initially, the film bag is put into the carton H5, and the carton H5 is placed in the carton placement unit H1. The lifting drive device H4 drives the carton placement unit H1 to drive the carton H5 and the diaphragm ring H1-3 to rise and align with the diaphragm ring removal unit H2 for inspection. The two sets of telescopic drive devices of the diaphragm ring removal unit H2 make the removal electromagnet H2-1 and the magnetic attraction part H1-31 of the diaphragm ring H1-3 accurately aligned. After the alignment verification is completed, the lifting drive device H4 drives the carton H5 and the diaphragm ring H1-3 to move downward and horizontally to the bottom of the box opening limit mechanism H3-1 of the material receiving translation and rotation drive unit H3. The lifting drive device H4 causes the carton H5 and the diaphragm ring H1-3 to rise, and the carton H5 is clamped to the box opening limit mechanism H3-1. The material receiving translation and rotation drive unit H3 causes the carton H5 to flip over and open toward the layered material receiving and packing device G for receiving the material. The prior art has a very difficult problem to solve in bagging and boxing, that is, after the film bag is put into the carton, if the film bag is easily deviated, shifted, dropped or slipped into the bottom of the box when the product is automatically loaded by a machine. Therefore, the prior art often faces a dilemma: either automate the boxing without putting a large film bag on the product. This method results in that the material can only be taken out in a scattered manner when taking it from the carton, and it is easy to contaminate and dirty the product, which does not meet the hygiene requirements; or put the film bag on first and then put the products in one by one manually, but the work efficiency is low and the products are not neatly arranged (affected by various unstable factors of the workers). The present invention adopts a diaphragm ring H1-3 to fix the film bag, which can effectively prevent the film bag from wrinkling, shifting and sliding. At the same time, it cooperates with other equipment to realize the functions of automatic boxing and removal of the diaphragm ring H1-3 after bagging, ensuring product hygiene, neat product boxing and high work efficiency.The carton placement unit is provided with a carton limit frame H1-1 that can carry cartons and a clutch support side panel H1-14. The side of the clutch support side panel H1-14 is provided with a guide rail H1-17. The guide rail H1-17 is slidably provided with a slider H1-18. The slider H1-18 is fixed with a latch connecting seat H1-19. The latch connecting seat H1-19 is provided with a latch H1-20 and the latch connecting seat H1-19 can be fixedly connected to the aluminum profile by screws. According to actual needs, the latch connecting seat H1-19 can be locked in different positions of the aluminum profile. In actual application, the position and quantity of the latch H1-20 and the latch connecting seat H1-19 can be adjusted according to specific circumstances. However, no matter how the position and quantity are adjusted, this technical solution falls within the scope of protection required by the present invention. Corresponding to the latch H1-20, a latch hole seat H3-2 is fixed to the back plate of the rotating seat H3-5 of the material receiving translation and rotation drive unit H3. The latch hole seat H3-2 is provided with a latch hole. The latch H1-20 corresponds to the latch hole of the latch hole seat H3-2 and can be assembled and plugged. When the lifting drive device H4 drives the carton placement unit H1 to rise toward the box opening limit mechanism H3-1, the latch H1-20 can be inserted into the corresponding latch hole seat H3-2 on the back plate of the rotating seat H3-5 to play a role in reinforcing the connection. In order to further strengthen the firmness of the connection, the back plate of the rotating seat H3-5 of this embodiment can also be provided with an electromagnet for adsorbing the clutch support side plate H1-14 to adsorb the column diaphragm ring H1-3 and the carton H5. The diaphragm ring H1-3 is provided with a portion that can be adsorbed by the electromagnet, and can also be made entirely of iron, or the main body can be made of stainless steel and the portion that needs to be adsorbed is made of iron.

[0128] In order to realize the flipping of the carton, the lower part of the rotating seat H3-5 of the material receiving and translational rotation drive unit H3 of this embodiment is fixed with a rotating shaft H3-8, and the rotating shaft H3-8 is rotatably mounted on the bearing seat H3-9. The bearing seat H3-9 is fixed to the translational rotation connecting seat H3-10. The upper part of the rotating seat H3-5 is hinged to one end of the rotating connecting rod H3-11, and the other end of the rotating connecting rod H3-11 is pushed and pulled by the cylinder H3-12. The box opening limiting mechanism H3-1 comprises a box opening gate support frame H3-2, a gate H3-3, and a gate drive unit H3-4. The box opening gate support frame H3-1 is mounted on the rotating base H3-5 of the material splicing translation and rotation drive unit H3. Tapered limit blocks H3-6 are installed on the inner corners of the box opening gate support frame H3-1. The gate drive unit H3-4 is mounted on the side of the box opening gate support frame H3-1 and drives the gate H3-3 to move via a connecting plate H3-13. The box opening of the carton H5 is locked in the box opening limiting mechanism H3-1 and rotates with the box opening limiting mechanism H3-1. After rotation, it aligns with the discharge port of the layer-by-layer splicing conveyor. The gate H3-3 is gradually raised by the gate drive unit H3-4, preventing products delivered by the layer-by-layer splicing conveyor from falling out of the carton H5.

[0129] In this embodiment, the lifting drive device H4 is composed of a motor, a transmission assembly, a gear and a rack 4-12. The rack is connected to the clutch lifting seat, the gear is engaged with the rack, and the gear is driven to rotate by the motor through the transmission assembly.

[0130] In this embodiment, the diaphragm ring removal unit includes a removal support frame H2-4, an adjustable stroke cylinder H2-3, a removal lifting structure H2-2, and an electromagnet H2-1. The adjustable stroke cylinder H2-3 is mounted on the removal support frame H2-4 and drives the removal lifting structure H2-2 to move up and down. The removal lifting structure H2-2 is provided with an electromagnet H2-1 that can absorb the diaphragm ring. The frame of the removal lifting structure H2-2 is made of aluminum profile. The electromagnet H2-1 can be installed at any position on the aluminum profile through a connector, and the position of the electromagnet H2-1 on the aluminum profile can be adjusted at any time as needed. When the carton specifications need to be changed, the clutch carton placement unit automatically operates to adjust the limit block corresponding to the size of the box opening limit mechanism, and then runs to the diaphragm ring removal unit to adjust the electromagnet. After the verification is completed, the above-mentioned operation can be carried out.

[0131] The actions of the packing device are as follows:

[0132] (1) Manually pack the film bags and diaphragm ring cartons;

[0133] (2) Place the carton on the carton clutch placement unit;

[0134] (3) The carton clutch placement unit automatically runs and docks with the box mouth limit mechanism, rotates to pick up the material, and then runs to the diaphragm ring removal unit to pull out the diaphragm ring. When the carton specifications need to be changed, the clutch carton placement unit automatically runs and adjusts the limit block with the corresponding size of the box mouth limit mechanism, and then runs to the diaphragm ring removal unit to adjust the electromagnet. After the verification is completed, it can operate according to the above actions.

[0135] After completing the packing, it moves to the diaphragm plate loading and unloading station and then sends the whole box of finished products to the station to complete the packing action.
