Description

Technical Field

[0001] This utility model relates to the field of automatic packaging technology, and in particular to a fully automatic rapid adjustment box packing machine. Background Technology

[0002] A case packer is a mechanical device that loads glass bottles, plastic bottles (barrels), metal barrels, flexible packaging, cardboard boxes, etc., into prepared cases using mechanical transmission. Currently, the most commonly used case packers in China employ either drop or gripping methods. Their working principle involves arranging or measuring / counting the products to be packaged, then loading them into the case via a gripping / dropping mechanism. Both drop and gripping methods have their advantages and disadvantages. Drop packers are not suitable for fragile or explosive products, but they offer high output and a wider range of applicable products. Gripping machines offer better stability and cause less damage to the product.

[0003] In gripper-type case packers, a bottle conveyor typically transports the arranged bottles to a designated position for alignment. After alignment, a bottle pusher, powered by a cylinder, pushes the bottles to a gripping mechanism, which then transfers the bottles into cartons. Many bottles to be packaged use the same neck size but have different body dimensions. Consequently, the spacing between adjacent gripper components used for gripping the bottles varies. Furthermore, due to the size differences between the bottles, the distance the pusher travels also differs, requiring manual adjustment each time production changes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic and rapid adjustment case packing machine that can quickly adjust the spacing of the gripper assembly and the pushing distance of the bottle pusher according to the different sizes of the bottles, eliminating manual adjustment and improving production changeover efficiency.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A fully automatic, high-speed adjustable case packing machine includes a frame and a bottle feeder disposed within the frame. One side of the bottle feeder is equipped with a bottle pushing device, and the other side is sequentially equipped with a transition conveyor and a case feeder. A bottle gripping mechanism is mounted above the transition conveyor. The bottle gripping mechanism includes a variable-pitch module and multiple gripper assemblies mounted on each actuating end of the variable-pitch module. The bottle pushing device includes a bottle pushing assembly slidably mounted on the frame along a direction perpendicular to the bottle feeder. A bottle pushing motor and a synchronous shaft, connected by a chain drive, are fixedly and rotatably mounted on the bottle pushing assembly. Gears are fixedly mounted at both ends of the synchronous shaft, and a rack meshing with the gears is provided on the frame.

[0007] Furthermore, it also includes a bottle sorting machine with a split structure located at the entrance of the bottle feeder. The bottle feeder has dual bottle feeding channels, and the bottle gripping mechanism has two adjustable spacing modules to form two rows of gripper assemblies.

[0008] Furthermore, the bottle separating machine includes a frame, a conveyor for conveying bottles is provided in the middle of the frame, a pair of adjustable-spaced first connecting plates are suspended at one end of the top, and a pair of adjustable-spaced second connecting plates are movably suspended at the other end. A retractable separating plate is hinged between the first and second connecting plates to form a bottle separating channel. Bottle blocking mechanisms are provided at both ends of the bottle separating channel.

[0009] Furthermore, a synchronous belt linear mechanism is provided at the top of the frame, and a forward and reverse screw adjustment mechanism is connected below the synchronous belt linear mechanism. The two second connecting plates are respectively installed on the two moving blocks of the forward and reverse screw adjustment mechanism.

[0010] Furthermore, the dividing plate includes a first dividing plate and a second dividing plate that are aligned together. A first guide rail is mounted parallel to the side of the first dividing plate, and a slider that is slidably mounted on the first guide rail is fixed to the second dividing plate.

[0011] Furthermore, the bottle feeder includes two parallel, synchronously moving mesh belt conveyor assemblies, with a gap between the two mesh belt conveyor assemblies, and a liftable central guardrail is provided in the gap.

[0012] Furthermore, a liftable side railing is provided between the transition conveyor and the bottle feeder. A horizontal bar is provided parallel to the top of the side railing, and a first lifting cylinder is fixedly mounted on the horizontal bar. The piston rod of the first lifting cylinder is set vertically downward and fixedly connected to the side railing.

[0013] Furthermore, a second guide rail is fixedly mounted parallel to the side of the rack. Both ends of the bottle pusher assembly and the crossbar are mounted on the corresponding second guide rail via sliders. The end of the second guide rail is provided with a fixed seat fixed to the frame portion. An adjusting rod is provided between the fixed seat and the crossbar. One end of the adjusting rod is fixedly connected to the crossbar, and the other end passes through the fixed seat and is connected to the fixed seat with a quick-locking screw.

[0014] Furthermore, the top of the frame is provided with a translation mechanism, the translation mechanism is provided with a lifting mechanism, the bottom of the lifting mechanism is fixedly connected with a connecting seat, the connecting seat is provided with an electric screw adjustment assembly, one of the pitch modules is fixedly suspended on the connecting seat, and the other pitch module is fixedly installed on the moving block of the electric screw adjustment assembly.

[0015] Furthermore, it also includes a box guiding mechanism, which includes a synchronous belt servo lifting mechanism and lifting guide rails located on the side of the box feeder. Two lifting guide rails are arranged in parallel and vertically. A lifting bucket frame adapted to the box is provided between the two lifting guide rails. The two ends of the lifting bucket frame are connected to the corresponding guide rails by sliders.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] (1) This utility model optimizes the structure of the traditional bottle gripping mechanism and bottle pushing device by installing each gripper assembly for gripping bottles on the execution end of the variable pitch module, thereby realizing automatic and rapid adjustment of the spacing of the gripper assemblies. At the same time, a bottle pushing motor is used as the power source of the bottle pushing device. The synchronous shaft is driven by the motor to rotate, thereby realizing the translation of the bottle pushing assembly. Compared with the traditional cylinder push, by controlling the rotation of the motor, the bottle pushing spacing can be directly adjusted according to the size of the bottle, thereby improving the overall production efficiency.

[0018] (2) This utility model uses a bottle sorting machine to send the bottles to two bottle feeding channels, thereby enabling two rows of bottles to be pushed at once. It is also equipped with two rows of gripper components, which can grab two rows of bottles at once, improving the packing efficiency. At the same time, the bottle sorting machine and the machine frame adopt a split structure design, which is convenient for movement and replacement. The appropriate model can be selected according to production needs.

[0019] (3) This utility model uses a connecting plate with adjustable spacing at both ends to realize the spacing adjustment of the two dividing plates, thereby forming bottle dividing channels of different widths to meet different bottle dividing needs. At the same time, the connecting plate at one end can be moved to realize the separate delivery of bottles in the same channel to different bottle delivery channels of the bottle feeder.

[0020] (4) This utility model uses a synchronous belt linear mechanism to drive the synchronous translation of two second connecting plates, thereby realizing the translation of the outlet of the bottle-splitting channel and connecting to different bottle-feeding channels. The spacing between the two connecting plates is adjusted by a positive and negative screw adjustment mechanism. The structure is simple and the adjustment is convenient.

[0021] (5) This utility model achieves the sliding connection between the first dividing plate and the second dividing plate through the first guide rail structure, so that when one end of the bottle dividing channel moves, the length of the dividing plate can be extended or retracted, which will not interfere with the normal movement of the bottle dividing channel outlet, and at the same time ensures that the two sides of the bottle dividing channel have relatively rigid dividing plates, thereby limiting the bottle body.

[0022] (6) This utility model sets side guardrails and central guardrails to limit the position of one row of bottles, and sets the central guardrail and bottle pusher assembly to limit the position of another row of bottles, thus preventing bottles from being misaligned.

[0023] (7) This utility model realizes the dual-channel setting of the bottle feeder through the liftable guardrail. When the bottle is pushed, the central guardrail is lowered to the bottom of the bottle feeding channel and the side guardrail is raised to the top of the bottle, which will not affect the normal operation of the bottle pushing component.

[0024] (8) This utility model uses an electric screw adjustment assembly to drive one of the pitch modules to move closer to and further away from another module, thereby achieving pitch adjustment.

[0025] (9) This utility model achieves sliding connection between the side guardrail and the bottle pusher assembly and the frame by means of guide rail and slider. The structure is simple. The distance between the side guardrail and the center guardrail is adjusted by means of adjustment rod. The distance between the bottle pusher assembly and the center guardrail is adjusted by means of movement of the bottle pusher assembly. Thus, the size adjustment of the two bottle feeding channels is realized, so that they can better fit the bottle feeding needs of different bottles and ensure that the bottles are arranged neatly.

[0026] (10) By setting a box guide mechanism, the box opening of the box is kept open by the lifting bucket frame, which makes it easier for the bottle grabbing mechanism to put the bottle. At the same time, the lifting of the lifting bucket frame is achieved by a synchronous belt servo lifting mechanism. The lifting height is adjusted by controlling the motor rotation according to the height of the box, which makes it more versatile. Attached Figure Description

Detailed Implementation

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] (Example 1)

[0037] like Figures 1 to 5 The fully automatic high-speed adjustable case packing machine shown includes a frame 1, and a bottle feeder 2, a bottle pusher 3, a transition conveyor 4, a case feeder 5, and a bottle gripping mechanism 6, all housed within the frame 1. The bottle feeder 2 and case feeder 5 are arranged in parallel, respectively conveying bottles to be packaged and cases that have already been opened. The bottle pusher 3 is located on the side of the bottle feeder 2 away from the case feeder 5, pushing the bottles on the bottle feeder 2 towards the case feeder 5. The transition conveyor 4 is located between the bottle feeder 2 and the case feeder 5, with its conveying direction perpendicular to the case feeding direction. It is used to store the bottles pushed by the bottle pusher 3. The bottle gripping mechanism 6 is mounted above the transition conveyor 4, used to grip the bottles on the transition conveyor 4 and transfer them to the cases on the case feeder 5, completing the automatic case packing.

[0038] Specifically, the bottle feeder 2 is equipped with dual bottle feeding channels, and the bottle gripping mechanism 6 has two adjustable-pitch modules, forming two rows of gripper assemblies to improve packing efficiency. In order to smoothly deliver the bottles from the previous process into the two bottle feeding channels, this embodiment has a bottle separating machine 7 at the entrance of the bottle feeder 2. The bottle separating machine 7 and the bottle feeder 2 adopt a separate structure design, which is convenient for movement and replacement, and the appropriate model can be selected according to production needs.

[0039] The bottle sorting machine 7 includes a frame 7-1, a conveyor, a first connecting plate 7-2, a second connecting plate 7-3, a forward / reverse screw adjustment mechanism 7-4, a synchronous belt linear mechanism 7-5, a sorting plate 7-6, and a bottle-blocking mechanism 7-7. The conveyor is located in the middle of the frame 7-1 and is used to transport bottles. The synchronous belt linear mechanism 7-5 is located at the top of the frame 7-1 and connects to one end of the bottle conveyor 2. There are two first connecting plates 7-2, two second connecting plates 7-3, and two forward / reverse screw adjustment mechanisms 7-4. The two first connecting plates 7-2 are respectively fixedly connected to two moving blocks of the forward / reverse screw adjustment mechanism 7-4, which is fixed to the other end of the top of the frame 7-1. The two second connecting plates 7-3 are connected to the other forward / reverse screw adjustment mechanism 7-4 in the same way. This forward / reverse screw adjustment mechanism 7-4 is connected to the synchronous belt linear mechanism 7-5 for transmission, enabling both adjustment of the spacing between the connecting plates and movement of the two second connecting plates 7-3. Two dividing plates 7-6 are provided, with their ends hinged to the corresponding first connecting plate 7-2 and second connecting plate 7-3 via pin holes, forming two bottle-dividing channels. Bottle-blocking mechanisms 7-7 are located at both ends of the bottle-dividing channels. Each dividing plate 7-6 includes a first dividing plate 7-6-1 and a second dividing plate 7-6-2 aligned together. A first guide rail 7-6-3 is mounted parallel to the side of the first dividing plate 7-6-1, and a slider is fixedly mounted on the second dividing plate 7-6-2 and slidably mounted on the first guide rail 7-6-3. This allows the dividing plates 7-6 to be retractable, ensuring that they do not interfere with the normal movement of the bottle-dividing channel outlet while maintaining relatively rigid dividing plates on both sides of the bottle-dividing channel to limit the movement of the bottles.

[0040] The bottle feeder 2 includes two parallel, synchronously moving mesh belt conveyor assemblies 2-1. There is a gap between the two mesh belt conveyor assemblies 2-1. A crossbeam 8 is fixedly mounted on the frame part 1 directly below the gap. A second lifting cylinder 9 is vertically fixed on the crossbeam 8. The piston rod of the second lifting cylinder 9 is vertically upward and fixedly connected to the central guardrail 10. The second lifting cylinder 9 drives the central guardrail 10 to move up and down.

[0041] A pair of parallel second guide rails 11 and a pair of racks 12 are fixedly mounted above both ends of the bottle feeder 2. A crossbar 13 is vertically arranged between the two second guide rails 11. The two ends of the crossbar 13 are slidably mounted on the second guide rails 11 via sliders. A first lifting cylinder 14 is fixedly mounted on the crossbar 13. The piston rod of the first lifting cylinder 14 is vertically downward and connected to a side guardrail 15 located on the side of the central guardrail 10 near the box feeder. The first lifting cylinder 14 drives the side guardrail 15 to move up and down. A fixed seat 16 is fixedly mounted on the frame at the end of the second guide rail 11 away from the box feeder. An adjusting rod 17 is provided between the fixed seat 16 and the crossbar 13. One end of the adjusting rod 17 is fixedly connected to the crossbar 13, and the other end passes through the fixed seat 16 with a gap and is connected to the fixed seat 16 by a quick-locking screw.

[0042] The bottle pushing device 3 includes a bottle pushing assembly 3-1 slidably mounted on the second guide rail 11 via a slider. The bottle pushing assembly 3-1 is located on the side of the central guardrail 10 away from the case feeder. A bottle pushing motor 3-2 and a synchronous shaft 3-3, connected by a chain drive, are fixedly and rotatably mounted on the assembly. Gears 3-4 that mesh with corresponding racks 12 are fixed at both ends of the synchronous shaft 3-3. The bottle pushing motor 3-2 drives the synchronous shaft 3-3 to rotate, and through the transmission of the gears and racks, the bottle pushing assembly 3-1 translates along the bottle feeding direction perpendicular to the bottle feeder 2.

[0043] The distance between the side guardrail 15 and the central guardrail 10 can be adjusted by adjusting rod 17, and the distance between the bottle pusher assembly 3-1 and the central guardrail 10 can be adjusted by moving the bottle pusher assembly 3-1. This allows for size adjustment of the two bottle feeding channels, making them more suitable for feeding different bottle sizes and ensuring neat bottle arrangement. Furthermore, both the side guardrail 15 and the central guardrail 10 are height-adjustable structures, so they will not interfere with the normal use of the bottle pusher assembly 3-1.

[0044] The top of the frame 1 is equipped with a translation mechanism 18, and a lifting mechanism 19 is mounted on the translation mechanism 18. A connecting seat 20 is fixedly connected to the bottom of the lifting mechanism 19, and an electric screw adjustment assembly 21 is mounted on the connecting seat 20. The bottle gripping mechanism 6 includes two sets of parallel variable-pitch modules 6-1. One variable-pitch module is fixedly suspended on the connecting seat 20, and the other variable-pitch module is fixedly mounted on the moving block of the electric screw adjustment assembly 21, thereby achieving adjustable spacing. Each actuator end of each variable-pitch module 6-1 is fixedly equipped with a gripper assembly 6-2, which can grip two rows of bottles at a time.

[0045] To facilitate the smooth placement of bottles into the box, this embodiment also includes a box guiding mechanism 22. The box guiding mechanism 22 includes a synchronous belt servo lifting mechanism 22-1 and lifting guide rails 22-2 located on the side of the box feeder away from the bottle feeder. Two lifting guide rails 22-2 are arranged parallel to each other and vertically. A lifting bucket frame 22-3 adapted to the box is provided between the two lifting guide rails 22-2. The two ends of the lifting bucket frame 22-3 are detachably connected to the corresponding guide rails via sliders. The lifting bucket frame 22-3 keeps the box opening open, making it easier for the bottle-grabbing mechanism 6 to place the bottle. The lifting of the lifting bucket frame is achieved through the synchronous belt servo lifting mechanism, and the lifting height can be adjusted by controlling the motor rotation according to the height of the box, thus improving versatility.

[0046] In this embodiment, the bottle sorting machine 7 is an independent mechanism with a design that allows for easy movement and replacement, and the model can be selected according to production needs. Bottles enter the bottle feeder 2 via the bottle sorting machine 7. A photoelectric detection and counting system is set up, and once a specified number is reached, the bottle pusher 3 pushes the bottles. The bottle pusher 3 then resets, and subsequent bottles continue to enter, repeating the process. Cartons reach a designated position via the carton feeder, and the lifting hopper frame 22-3 descends to a set position. The bottle gripping mechanism 6 operates, grabbing the bottles from the transition conveyor 4 and conveying them to the top of the carton feeder via the translation mechanism 18 and the lifting mechanism 19. After descending, the gripper assembly is released, completing the carton loading. The lifting hopper frame 22-3 rises, and the carton is then moved from the carton feeder to the next station, completing the carton loading process.

[0047] This invention optimizes the structure of traditional bottle gripping mechanisms and bottle pushing devices by installing each gripper assembly for gripping bottles on the execution end of the variable pitch module, thereby achieving automatic and rapid adjustment of the gripper assembly spacing. At the same time, a bottle pushing motor is used as the power source for the bottle pushing device, and the synchronous shaft is driven by the motor to rotate, thereby realizing the translation of the bottle pushing assembly. Compared with the traditional cylinder pushing, by controlling the rotation of the motor, the bottle pushing spacing can be directly adjusted according to the size of the bottle, improving the overall production change efficiency.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
