Description

Technical Field

[0001] This invention relates to the field of packaging machinery technology, specifically to an automatic pre-packaging mechanism and packing machine for vertically arranged bags in a vertical row. Background Technology

[0002] With the market-oriented upgrading of the packaging industry and the diversification of end-consumer demands, various packing operations are placing higher demands on the regularity of material arrangement and equipment adaptability. Vertical packing of materials, applicable to display cases, is a crucial scenario, while also needing to meet the general packing requirements of ordinary packaging boxes. Currently, vertical packing of bagged materials often employs a multi-station, step-by-step operation mode, using multiple independent mechanisms to complete material conveying, positioning, transfer, and boxing processes. This results in low operational efficiency and poor coordination. Existing vertical packing equipment has a fixed structure and insufficient adaptability. It struggles to meet the specific requirements of display cases for material arrangement regularity (maintaining materials upright and neatly arranged to suit display needs) and cannot flexibly adapt to different sizes of ordinary cartons. Furthermore, poor coordination between mechanisms easily leads to problems such as material jamming and material misalignment, making it difficult to simultaneously address the diverse packing needs of both display cases and ordinary packaging boxes. Therefore, developing vertical packing equipment with strong adaptability, high stability, and flexible specification switching capabilities to solve the pain points of poor adaptability, low efficiency, and jamming in existing equipment has become an urgent need to meet various packing requirements. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic pre-packing mechanism and packing machine for vertically arranged bags, which realizes vertical bag packing, improves packing stability, and adapts to packing of different materials and specifications.

The buffer position vertical arrangement assembly and the vertical arrangement transfer assembly are respectively disposed above and below the slotted conveyor. The buffer position vertical arrangement assembly is used as a buffer dummy box to buffer the materials arranged vertically on the slotted conveyor. The slotted conveyor is used to transport the vertical bagged materials into the buffer dummy box space. The vertical arrangement transfer assembly is used to move the buffered and arranged materials in the buffer dummy box to the material packing gripping position. The slotted conveyor has multiple slots distributed laterally on the conveying surface. The longitudinal vertical arrangement and transfer assembly includes a lifting platform, a traverse trolley, and a dummy cassette. The front and rear ends of the dummy cassette are comb-tooth structures adapted to each slot, facilitating the front and rear ends to pass through each slot from below the conveyor surface to above the conveyor surface. The dummy cassette is set on the traverse trolley, which is set on the lifting platform. The lifting platform is used to drive the dummy cassette to rise and fall. After the dummy cassette rises from below the slot conveyor, passing through the slot, the vertically arranged bagged materials in the buffer dummy cassette are loaded into the dummy cassette. The traverse trolley is used to drive the dummy cassette to move longitudinally, so that the vertically arranged bagged materials are detached from the slot conveyor and moved to the material packing and gripping position.

The lifting screw is vertically mounted on the following baffle base plate via the lifting adjustment fixed frame. A movable nut is provided on the lifting screw, and the movable nut is connected to the lifting adjustment movable frame. One end of the lifting screw is connected to a rotary drive component. The rotary drive component drives the lifting screw to rotate, thereby causing the lifting adjustment movable frame to move up and down along the lifting screw via the movable nut. The flipping mechanism includes a flipping cylinder, which is mounted on the lifting and adjusting mechanism. The flipping cylinder drives the rotating baffle to flip and open, allowing the material to enter the dummy box space and be arranged in a limited position.

Together with the end baffle and gripping position tail plate, it forms a dummy box space. Both the end baffle and gripping position tail plate are comb-tooth structures adapted to each slot of the slotted conveyor channel. When the dummy box is moved and rises from below the slotted conveyor, the upper ends of the end baffle and gripping position tail plate extend from each slot to above the conveying surface of the slotted conveyor. A rotary drive mechanism is connected between the gripping position tail plate and the mounting plate.

[0010] Preferably, the rotary drive mechanism includes a gripping position cylinder, a tail plate rotating seat, and a mounting seat. The gripping position tail plate is fixedly connected to the tail plate rotating seat, and the tail plate rotating seat is rotatably mounted on the mounting seat.

Side plates are arranged on the side of the comb-tooth bottom plate, and the middle plate is set in the middle of the comb-tooth bottom plate. End baffles and gripping tail plates are set on the front and rear sides of the comb-tooth bottom plate. The comb structure of the comb-tooth bottom plate is adapted to each slot of the slot conveyor. When the dummy box is moved through the slot and rises, the comb-tooth bottom plate can lift the material from the bottom, so that the material is separated from the slot conveyor, which makes it easier for the dummy box to move the material. The detachable quick-change structure includes quick-change side pressure plates symmetrically arranged on both sides of the quick-change platform for clamping the quick-change bottom plate of the dummy box. The quick-change side pressure plate has a slot on its inner side, and the quick-change side pressure plate is inserted into the side end of the quick-change platform through the slot. The side of the quick-change side pressure plate is provided with a bolt with an adjustment handle. The bolt with the adjustment handle passes through the threaded hole on the quick-change side pressure plate and abuts against the quick-change platform. The upper inner end of the quick-change side pressure plate is pressed against the end of the quick-change bottom plate of the dummy box. The side end of the quick-change bottom plate of the dummy box is provided with a first wedge-shaped surface, and the inner side of the quick-change side pressure plate is provided with a second wedge-shaped surface. The second wedge-shaped surfaces of the two quick-change side pressure plates are respectively pressed onto the first wedge-shaped surfaces at both ends of the quick-change bottom plate of the dummy box.

[0012] Preferably, the translation trolley includes a wheeled base plate, two pulleys and a first guide rail. The wheeled base plate is set on the lifting platform. The two pulleys are arranged alternately on the wheeled base plate along the material conveying direction. A drive belt connects the two pulleys. One of the pulleys is connected to the trolley motor. Two first guide rails are arranged parallel to the material conveying direction on the pulley base plate. An installation plate is provided on the first guide rail. The installation plate is connected to the drive belt. The translational dummy box is set on the installation plate. The trolley motor drives the pulley to rotate, thereby driving the installation plate and the translational dummy box on it to move back and forth along the first guide rail through the drive belt. The lifting platform includes a linear slide rail, a drive pulley, a driven pulley, and a lifting platform motor. The linear slide rail is arranged vertically, and the drive pulley and driven pulley are arranged sequentially along the linear slide rail. A synchronous belt connects the drive pulley and driven pulley, and a tensioning pulley is provided on one side of the synchronous belt. The pulley base plate of the translation trolley is set on the linear slide rail of the lifting platform and connected to the synchronous belt. The drive pulley is connected to the lifting platform motor. The lifting platform motor drives the drive pulley to rotate, thereby driving the pulley base plate of the translation trolley to move up and down along the linear slide rail of the lifting platform through the synchronous belt.

[0013] A case packing machine includes a case packing robot and one or two automatic pre-packing mechanisms for vertically arranged bags as described above. The case packing robot is located above the material grabbing position at the output end of the slotted conveyor, and a material stacking robot is located above the material stacking position at the input end of the slotted conveyor. When there are two automatic pre-packing mechanisms for vertically arranged bags, the two slotted conveyors are symmetrically arranged with their output ends facing inwards and opposite each other. The packing robot is positioned above the material grabbing position at the output end of the two slotted conveyors. Each slotted conveyor is equipped with a material stacking robot at its input end. The two automatic pre-packing mechanisms for vertically arranged bags share one packing robot. The beneficial effects of this invention are: This invention uses a slotted conveyor to transport vertically bagged materials into a buffer position vertical arrangement assembly that serves as a buffer dummy box space. A longitudinal vertical arrangement transfer assembly then moves the buffered materials from the dummy box to the material grabbing position, preparing for subsequent grabbing and boxing. This solves the current problems of unstable vertically bagged material arrangement and low boxing efficiency, enabling vertical bag boxing. It improves boxing stability and adapts to different materials and specifications, offering advantages such as high stability, good boxing efficiency, wide application range, and convenient changeover.

[0033] Example 1 An automatic pre-packing mechanism for vertically arranged bags, such as... Figures 2-12 The system includes a slotted conveyor, a buffer position vertical arrangement assembly 200, and a longitudinal vertical arrangement transfer assembly 300. The buffer position vertical arrangement assembly 200 and the longitudinal vertical arrangement transfer assembly 300 are respectively arranged above and below the slotted conveyor. The buffer position vertical arrangement assembly 200 is used as a buffer dummy box to buffer vertically arranged bagged materials placed on the slotted conveyor. The slotted conveyor is used to transport the moving vertically arranged bagged materials into the buffer dummy box space. The longitudinal vertical arrangement transfer assembly 300 is used to move the buffered materials in the buffer dummy box to the material packing gripping position. The slotted conveyor has multiple slots arranged side by side along the transverse direction on its conveying surface; The longitudinal vertical arrangement and transfer assembly 300 includes a lifting platform 310, a traverse trolley, and a dummy cassette. The front and rear ends of the dummy cassette are both comb-tooth structures adapted to each slot, which facilitates the front and rear ends to pass through each slot from below the conveyor surface to above the conveyor surface. The dummy cassette is set on the traverse trolley, which is set on the lifting platform 310. The lifting platform 310 is used to drive the traverse trolley and the dummy cassette to lift and lower. After the dummy cassette rises from below the slot conveyor, it lifts the vertically arranged bagged materials inside the dummy cassette. The traverse trolley is used to drive the dummy cassette to move longitudinally, so that the arranged vertically arranged bagged materials are removed from the slot conveyor and moved to the material packing and gripping position.

[0034] Furthermore, the slotted conveyor is a slotted belt conveyor 100; the slotted belt conveyor 100 includes two pulleys, and multiple belts are arranged side by side at intervals between the two pulleys, forming a slot between adjacent belts; the drive motor of the slotted belt conveyor 100 is a servo motor.

[0035] Example 2 Based on Example 1, the buffer position vertical arrangement component is further defined, and the performance of Example 2 is even better after the definition is defined.

[0036] The buffer support assembly 200 includes a buffer material support structure and two limiting baffles. The two limiting baffles are arranged on both sides of the conveying passage of the slotted conveyor to limit the lateral displacement of the vertical bagged material. The two limiting baffles are a side guard plate 213 and a movable side guard plate 214. The side guard plate 213 and the movable side guard plate 214 are provided to ensure the limiting arrangement on both sides. By adjusting the distance between the movable side guard plate 214 and the side guard plate 213, the width of the conveying channel can be adjusted to adapt to different gripping widths. The distance between the buffer material support structure and the conveying surface of the slotted conveyor belt 100 can be adjusted to adapt to the height of the material, and is used to buffer half-boxes of vertical bagged material and keep the material upright. The buffer material support structure includes a following bottom plate 203, a following lifting rib plate 204, a push-pull mechanism, and a vertical push-pull mechanism. The following bottom plate 203 is provided with a first linear guide rail 205 arranged horizontally along the conveying direction. A slide plate is provided on the first linear guide rail 205. The push-pull mechanism is set on the following bottom plate 203 and is connected to the slide plate, driving the slide plate to move back and forth along the first linear guide rail 205. The vertical push-pull mechanism is set on the slide plate, and the slide plate is provided with a vertically arranged second linear guide rail 207. The following stop lifting rib plate 204 is set on the second linear guide rail 207. The vertical push-pull mechanism is connected to the following stop lifting rib plate 204, and drives the following stop lifting rib plate 204 to move up and down along the second linear guide rail 207. A following baffle 208 is provided on the following baffle lifting rib plate 204, and a rotating baffle 210 is provided on the following baffle bottom plate 203. The rotating baffle is connected to a flipping mechanism, which drives the rotating baffle to flip. The following baffle 208 and the rotating baffle 210 are arranged sequentially at intervals along the conveying direction of the slotted conveyor. Two limit baffles are respectively arranged on both sides of the following baffle 208 and the rotating baffle 210. The following baffle 208, the rotating baffle 210 and the two limit baffles together form a buffer dummy box. The following baffle 208 is a quick-change part, which can be adjusted according to different needs. The same packing method can be changed; the vertical push-pull mechanism drives the following baffle 204 to move along the second linear guide 207 to the corresponding height according to the height of the vertical bagged material, so that the following baffle 204 can hold the vertical bagged material from the front; when the slotted conveyor moves the vertical bagged material on it forward by one material body position along the material conveying direction, the push-pull mechanism drives the following baffle 204 to move forward by one material body position along the first linear guide 205, and the rotating baffle 210 flips upward to buffer the false The inlet of the container opens, and the material stacking robot places the horizontally lying, vertically packed materials against the inlet of the buffer dummy container on the slotted conveyor, next to the previous vertically packed material. The rotating baffle 210 flips downwards, pressing against the back of the vertically packed material, and the buffer dummy container closes. The above steps are repeated, and the slotted conveyor moves the vertically packed materials in the buffer dummy container one material position. The lifting baffle 204 also moves forward one material position. The rotating baffle 210 flips upwards, and the materials are stacked again at the inlet of the buffer dummy container. A vertical bag of material is stacked in a buffer box until it reaches a set number of rows. Then, the horizontal dummy box below the conveying surface of the slotted conveyor moves upward with the help of the lifting platform. The upper part of the horizontal dummy box passes through the slot on the conveying surface of the slotted conveyor and loads the material from the buffer box into the horizontal dummy box. The vertical push-pull mechanism drives the following baffle 204 and its following baffle 208 and rotating baffle 210 to move upward and separate from the vertical bag of material. The horizontal dummy box moves with the arranged material to the material loading and grabbing position.

[0037] Furthermore, the lower ends of the following baffle 208 and the rotating baffle 210 are both comb-tooth structures, which are adapted to the slots and the distance between the slots of the slotted conveyor. This prevents the bottom of the following baffle 208 and the rotating baffle 210 from directly contacting the slotted conveyor during the downward movement.

[0038] Furthermore, the push-pull mechanism includes an electric cylinder 202 mounted on the follower base plate 203. The motor of the electric cylinder 202 is a servo motor 201. The electric cylinder 202 is connected to the slide plate, driving the slide plate and the follower lifting rib plate 204 on it to move synchronously along the first linear guide rail 205 following the feeding rhythm of the slotted conveyor. The vertical push-pull mechanism includes a first vertical cylinder 206 mounted on the slide plate. The movable end of the first vertical cylinder 206 is connected to the following baffle 204, which drives the following baffle 204 to move along the second linear guide rail 207. After the half-box arrangement is completed, the following baffle 208 moves upward under the push of the first vertical cylinder 206 to make room for the dummy box trolley.

[0039] Furthermore, a lifting adjustment mechanism is connected between the rotating baffle 210 and the following baffle base 203. The lifting adjustment mechanism includes a lifting adjustment fixed frame, a lifting adjustment movable frame, and a lifting screw 211. The lifting screw 211 is vertically mounted on the following baffle base 203 via the lifting adjustment fixed frame. The lifting screw 211 is connected to the lifting adjustment fixed frame via a bearing. A movable nut is provided on the lifting screw 211, which is connected to the lifting adjustment movable frame. One end of the lifting screw 211 is connected to a rotary drive component. The rotary drive component drives the lifting screw 211 to rotate, thereby causing the lifting adjustment movable frame to move up and down along the lifting screw 211 via the movable nut, providing blocking and limiting for different material heights. The flipping mechanism is mounted on the following baffle base 203 via the lifting adjustment movable frame of the lifting adjustment mechanism. The rotating baffle 210 is hinged to the lifting and adjusting movable frame via a rotating shaft. The flipping mechanism includes a flipping cylinder 209, which is mounted on the lifting and adjusting movable frame of the lifting and adjusting mechanism. The flipping cylinder 209 drives the rotating baffle 210 to flip and open, allowing the material to enter the dummy box space and be arranged in a limited position.

[0040] Furthermore, the tilting cylinder 209 is a circular cylinder, and the rotary drive component is a handwheel 212, or it can be a rotary drive motor.

[0041] Furthermore, the translational dummy box includes an end baffle 329, a middle baffle assembly 330, and a gripping tail plate 331. The translational trolley is equipped with a mounting plate, and the end baffle 329, the middle baffle assembly 330, and the gripping tail plate 331 are sequentially arranged on the mounting plate along the conveying direction. The intermediate baffle assembly 330 includes a side plate 338, which is disposed on one side of the end baffle 329 and the gripping tail plate 331, forming a dummy box space together with the end baffle 329 and the gripping tail plate 331. The end baffle 329 and the gripping tail plate 331 are both comb-tooth structures adapted to each slot of the conveying channel of the slotted conveyor (corresponding to the front and rear ends of the translating dummy box being comb-tooth structures adapted to each slot). When the translating dummy box rises from below the slotted conveyor, the upper ends of the end baffle 329 and the gripping tail plate 331 extend from each slot to above the conveying surface of the slotted conveyor. A rotary drive mechanism is connected between the gripping tail plate 331 and the mounting plate.

[0042] Furthermore, the rotary drive mechanism includes a gripping cylinder 334, a tail plate rotating seat 335, and a mounting base. The gripping tail plate 331 is fixedly connected to the tail plate rotating seat 335, and the tail plate rotating seat 335 is rotatably mounted on the mounting base, which is set on the mounting plate. The movable end of the gripping cylinder 334 is hinged to the tail plate rotating seat 335. Through the extension and retraction of the gripping cylinder 334, the tail plate rotating seat 335 is driven to rotate around the mounting base, thereby causing the gripping tail plate 331 to flip and realize the opening and closing of the translational dummy box. When the gripping tail plate 331 flips to a horizontal position, the gripping tail plate 331 is lower than the conveying surface of the slotted conveyor, and the inlet of the translational dummy box opens. When the gripping tail plate 331 flips to a vertical position, the gripping tail plate 331 is parallel to the end baffle 329, and the inlet of the translational dummy box opens. The flipping mechanism of the grabbing tail plate 331 is particularly suitable for lateral dummy boxes with intermediate plates. When half-boxes of vertical bagged materials are arranged in the buffer dummy box, the horizontal lateral dummy box of the grabbing tail plate 331 rises from below the slotted conveyor to above the conveying surface. The arranged half-boxes of vertical bagged materials are loaded into the lateral dummy box space between the end baffle 329 and the intermediate plate. The buffer material support structure moves forward to the position between the intermediate plate and the grabbing tail plate 331. The buffer dummy box formed by the buffer material support structure stacks the vertical bagged materials in another space of the lateral dummy box. After the vertical bagged materials are stacked, the grabbing tail plate 331 flips to be vertical, the inlet of the lateral dummy box closes, and the lateral dummy box moves the arranged materials to the material packing grabbing position.

[0043] A longitudinal adjustment mechanism is connected between the end baffle 329 and the mounting plate; The longitudinal adjustment mechanism includes an end cylinder 332 and a second guide rail 333. The second guide rail 333 is arranged on the mounting plate along the material conveying direction. The end cylinder 332 is arranged parallel to the second guide rail 333 on the mounting plate. The movable end of the end cylinder 332 is fixedly connected to the end baffle 329. Through the extension and retraction of the end cylinder 332, the end baffle 329 is driven to reciprocate linearly along the second guide rail 333 to realize the material blocking limit adjustment of materials of different specifications.

[0044] Furthermore, the intermediate baffle assembly 330 also includes an intermediate plate 337, which is horizontally positioned in the middle of the translational dummy box, dividing the translational dummy box space into two parts. The intermediate plate 337 has a comb-like structure; it is particularly suitable for dividing vertical bagged materials into two spaces for easy gripping by subsequent clamps with corresponding intermediate baffle box grabbers, thus making the clamping more stable and preventing the materials from falling off when gripping.

[0045] The intermediate baffle assembly 330 also includes a dummy container quick-change bottom plate 339 and a quick-change platform 340. The intermediate plate 337 and the side plate 338 are fixedly connected to the dummy container quick-change bottom plate 339 to form a quick-change assembly. The quick-change platform 340 is connected to the dummy container quick-change bottom plate 339 of this quick-change assembly through a detachable quick-change structure. A comb-tooth bottom plate is provided between the bottom of the intermediate plate 337 and the top surface of the quick-change bottom plate 339 of the dummy box. The side plate 338 is arranged on the side of the comb-tooth bottom plate, the intermediate plate 337 is set in the middle of the comb-tooth bottom plate, and the end baffle 329 and the gripping tail plate 331 are set on the front and rear sides of the comb-tooth bottom plate. The comb structure of the comb-tooth bottom plate is adapted to each slot of the slotted conveyor. When the dummy box is moved through the slot and rises, the comb-tooth bottom plate can lift the material from the bottom, so that the material is separated from the slotted conveyor, which facilitates the movement of the material by the dummy box.

[0046] The detachable quick-change structure includes quick-change side pressure plates 341 symmetrically arranged on both sides of the quick-change platform 340 for clamping the quick-change bottom plate 339 of the dummy box. The quick-change side pressure plate 341 has a slot on its inner side. The quick-change side pressure plate 341 is inserted into the side end of the quick-change platform 340 through the slot. The side of the quick-change side pressure plate 341 is provided with a bolt with an adjustment handle 342. The bolt with the adjustment handle 342 passes through the threaded hole on the quick-change side pressure plate 341 and abuts against the quick-change platform 340. The upper inner end of the quick-change side pressure plate 341 is pressed against the end of the quick-change bottom plate 339 of the dummy box. The side end of the quick-change bottom plate 339 of the dummy box is provided with a first wedge-shaped surface, and the inner side of the quick-change side pressure plate 341 is provided with a second wedge-shaped surface. The second wedge-shaped surfaces of the two quick-change side pressure plates 341 are respectively pressed onto the first wedge-shaped surfaces at both ends of the dummy box quick-change bottom plate 339. The reset pin 343 is vertically arranged on the bottom of the dummy box quick-change base plate 339. The bottom of the quick-change platform 340 intermediate baffle assembly 330 is provided with a positioning hole that matches the reset pin 343. Through the cooperation of the reset pin 343 and the insertion positioning hole, the intermediate baffle assembly 330 and its dummy box quick-change base plate 339 can be quickly positioned.

[0047] Furthermore, the translation trolley includes a wheel base plate 321, two pulleys and a first guide rail 327. The wheel base plate 321 is set on the lifting platform 310. The two pulleys are arranged alternately on the wheel base plate 321 along the material conveying direction. A drive belt is connected between the two pulleys, and one of the pulleys is connected to the trolley motor. Two first guide rails 327 are arranged parallel to the material conveying direction on the pulley base plate 321. An installation plate is provided on the first guide rail 327. The installation plate is connected to the drive belt. The translational dummy box is set on the installation plate. The trolley motor drives the pulley to rotate, thereby driving the installation plate and the translational dummy box on it to move back and forth along the first guide rail 327 through the drive belt. The lifting platform 310 includes a lifting platform linear slide rail 318, a drive pulley 314, a driven pulley 316, and a lifting platform motor. The lifting platform linear slide rail 318 is arranged vertically. The drive pulley 314 and the driven pulley 316 are arranged sequentially along the lifting platform linear slide rail 318. A synchronous belt 315 connects the drive pulley 314 and the driven pulley 316. A tensioning pulley 317 is provided on one side of the synchronous belt 315. The pulley base plate 321 of the translation trolley is set on the lifting platform linear slide rail 318 and connected to the synchronous belt 315. The drive pulley 314 is connected to the lifting platform motor. The lifting platform motor drives the drive pulley 314 to rotate, thereby driving the pulley base plate 321 of the translation trolley to move up and down along the lifting platform linear slide rail 318 through the synchronous belt 315.

[0048] Furthermore, there are two active pulleys 314 and two passive pulleys 316, arranged in two groups side by side. The two active pulleys 314 are connected by an active rotating shaft, and the lifting platform motor is connected to the active rotating shaft.

[0049] Furthermore, each synchronous belt 315 is equipped with two tensioning pulleys 317, which are symmetrically arranged on both sides of the synchronous belt 315 and respectively cooperate with the driving pulley 314 and the driven pulley 316 to adjust the tension of the synchronous belt 315, prevent slippage or deviation during the transmission of the synchronous belt 315, and ensure that the lifting platform 310 lifts and lowers smoothly and accurately.

[0050] Furthermore, both the trolley motor and the lifting platform motor are servo motors; the lifting platform motor 311 and the trolley motor 322 adopt closed-loop synchronous control, and their action sequence is preset by the control system to ensure that after the lifting platform 310 is lifted into position, the translation trolley will start horizontal movement, avoiding interference that could cause material to tilt or be misaligned.

[0051] A type of case packer, such as Figure 1 As shown, it includes a packing robot and one or two automatic pre-packing mechanisms for vertically arranged bags as described above. The packing robot is positioned above the material grabbing position at the output end of the slotted conveyor, and a material stacking robot is positioned above the material stacking position at the input end of the slotted conveyor. The material stacking robot is used to pick up or grab the flat, vertically arranged bags of material and place them vertically into the buffer dummy box space on the slotted conveyor. Figure 13 As shown, the packing robot is used to reach into a dummy box to pick up and pack the vertically bagged materials arranged inside. Figure 14 As shown; When there are two automatic pre-packing mechanisms for vertically arranged bags, the two slotted conveyors are symmetrically arranged with their output ends facing inwards and opposite each other. Each slotted conveyor is equipped with a material stacking robot at its input end. The two automatic pre-packing mechanisms for vertically arranged bags share one packing robot. The two slotted conveyors are respectively arranged on both sides below the packing robot, and the packing robot covers the material packing gripping position at the output end of the two slotted conveyors.

[0052] The material stacking robot can be directly used to pick up or grab the flat, vertically bagged materials on the sorting conveyor and place them vertically into the buffer dummy box space on the slotted conveyor. Alternatively, a robotic arm can first pick up or grab the horizontally lying, vertically shaped bagged materials from the sorting conveyor and place them horizontally onto the slotted conveyor. Or, the sorting conveyor can directly transport the horizontally lying, vertically shaped bagged materials to the slotted conveyor, and then another robotic arm can pick up or grab the horizontally lying, vertically shaped bagged materials from the slotted conveyor and place them vertically into the buffer dummy box space on the slotted conveyor. Figure 15 As shown.

[0053] In this embodiment, a rectangular coordinate robot arm is selected as the packing gripper.

[0054] The working principle of this invention is as follows: Figures 2-6 As shown, the material stacking robot first picks up or grabs the flat, vertically bagged materials and places them vertically into the buffer dummy box space on the slotted conveyor for arrangement. After the vertically bagged materials are arranged in the buffer dummy box, the lifting platform drives the translation trolley and translation dummy box to rise. The upper part of the translation dummy box rises above the conveyor surface through its comb structure by passing through the corresponding slots on the conveyor surface. The materials arranged in the buffer dummy box are then loaded into the translation dummy box. The vertical arrangement component 200 in the buffer position is raised to make way for the translation dummy box to move. The translation trolley drives the translation dummy box and the materials arranged inside it to move along the length of the slot to the material packing gripping position, which is convenient for the subsequent packing gripper to grab and pack the materials.

[0055] This application provides an automatic pre-packaging mechanism for vertically arranged bags, which can be used to package vertically bagged materials into display boxes. It includes a slotted belt conveyor 100 for conveying vertically bagged materials, a buffer position vertical arrangement assembly 200 for orderly arranging materials in a buffer dummy box, and a vertical arrangement transfer assembly 300 for driving the translation of the dummy box to realize the material from the buffer dummy box to the rectangular coordinate grasping position.

[0056] The vertically arranged transfer assembly 300 includes a lifting platform 310 and a dummy box for translation, with a translation trolley at the bottom of the dummy box 320.

[0057] The lifting platform 310 includes a power source lifting platform motor 311 and a lifting platform reducer 312. The lifting platform reducer 312 is connected to the drive shaft 313 to output power, which drives the two drive pulleys 314 on the drive shaft 313 to transmit power to the two driven pulleys 316 through the synchronous belt 315. There is a tensioning pulley 317 responsible for tensioning. The pulley base plate 321 is mainly driven by the synchronous belt 315 to slide on the linear slide rail 318 of the lifting platform, so as to realize the up and down movement of the translation trolley.

[0058] The power source of the translation trolley consists of a trolley motor 322 and a trolley reducer 323; the power transmission mechanism is achieved by the cooperation of a first pulley 324, a second pulley 326 and a drive belt 325.

[0059] The first guide rail 327 is fixed on the pulley base plate 321, and the intermediate baffle assembly 330 slides relative to the pulley base plate 321 by relying on the first guide rail 327; the translational dummy box accommodating space is formed by the intermediate baffle assembly 330, the grabbing position tail plate 331, the end baffle 329 and the holding position lifting baffle 328.

[0060] The gripping tail plate 331 and the end baffle 329 are respectively located at both ends of the intermediate baffle assembly 330 and can be adjusted in position. The end baffle 329 can slide back and forth along the second guide rail 333 and is driven by the end cylinder 332 to adapt to the material blocking and limiting requirements of different specifications of materials.

[0061] The gripping tail plate 331 is used to close and seal the dummy box after it is filled with materials, ensuring that the vertical materials remain upright and do not tip over during the transfer process; a third guide rail 336 is configured at the bottom of the mechanism to enable the machine to be adjusted to accommodate materials of different specifications; the gripping cylinder 334 drives the tail plate rotating seat 335 to rotate, thereby causing the gripping tail plate 331 to flip, realizing the opening and closing action of the end space of the dummy box trolley.

[0062] The intermediate baffle assembly 330 is composed of an intermediate plate 337 and a side plate 338. The lower part of the intermediate baffle assembly 330 is equipped with a quick-change assembly consisting of a dummy box quick-change bottom plate 339, a quick-change platform 340, and a quick-change side pressure plate 341. Lateral locking is achieved via two adjustable handles 342, and bottom positioning is achieved via two reset pins 343. When changing product specifications, only the intermediate plate 337 needs to be replaced to complete the specification adaptation operation.

[0063] Furthermore, when the dummy box trolley completes its arrangement and moves to the gripping position, as it grips the material downwards at the Cartesian coordinate, the dummy box trolley moves downwards synchronously, connecting with the side plate that protects the material from tipping over, ensuring that the material remains within a closed dummy box space and does not tip over.

[0064] The working principle of the vertical bag vertical arrangement automatic pre-packing mechanism provided in this application embodiment is as follows: the packing machine continuously conveys the vertical bagged material through the slotted arrangement belt conveyor 100. The buffer position vertical arrangement component 200 relies on the servo motor 201, electric cylinder 202 and guide rail to form a following adjustment mechanism to follow, buffer, and orderly arrange the conveyed material, which can adapt to the limiting arrangement requirements of different packing forms, material height and gripping width. After the material is collected to the preset packing capacity, the vertical arrangement transfer component 300 relies on the synchronous linkage control of multiple servo motors to complete the whole process of receiving, limiting and surrounding and transferring the vertical bagged material to the rectangular coordinate gripping station.

[0065] Initially, the vertically arranged transfer assembly 300 is in standby and zero-state, and the lifting platform 310 and the various mechanisms of the translation trolley are reset and locked. This device uses a servo motor as the core power source. The core purpose is to achieve precise synchronous control of the multi-axis mechanism, ensuring that the timing and position of each action, such as lifting, translation, baffle adjustment, and tail plate flipping, are matched. This is the core of this patent.

[0066] When the material is conveyed to the designated position by the slotted belt conveyor 100, the buffer position vertical arrangement assembly 200 is driven by the servo motor 201 to operate the electric cylinder 202. The electric cylinder 202, installed on the follower baffle base plate 203, drives the follower baffle lifting rib plate 204 to slide along the first linear guide rail 205, achieving synchronous following movement with the belt conveyor's feeding rhythm. The first vertical cylinder 206 and the second linear guide rail 207 mounted on the follower baffle lifting rib plate 204 drive the follower baffle 208 to adaptively lift and avoid obstacles. The follower baffle 208 adopts a quick-change structure. It can adapt to different packing methods. After the half-box of materials is arranged, it is raised to make way for the dummy box to move and make room for passage. At the same time, the lower tilting cylinder 209 drives the rotating baffle 210 to tilt and open, guiding the material smoothly into the buffer dummy box space and limiting and regulating it. The rotating baffle 210 can be adjusted up and down through the lifting screw 211 and the handwheel 212 to adapt to different material heights. The side guard plate 213 and the adjustable movable side guard plate 214 cooperate with each other to realize the limited arrangement of materials on both sides. The gripping width can be adjusted according to the actual working conditions.

[0067] After the buffer position vertical arrangement assembly 200 completes the material arrangement, the lifting platform motor 311, in conjunction with the lifting platform reducer 312, receives a synchronous control signal and starts, driving the drive shaft 313 to rotate synchronously. This drives the drive pulley 314 to form a closed-loop synchronous transmission via the synchronous belt 315, tension wheel 317, and driven pulley 316. The traction pulley base plate 321 slides vertically along the linear slide rail 318 of the lifting platform, precisely driving the translation trolley to rise and fall smoothly to the designated material receiving position. Relying on the servo closed-loop synchronous characteristics, it ensures that the synchronous belt transmission stroke on both sides is consistent and that there is no skew in the lifting.

[0068] Then, the trolley motor 322 and the trolley reducer 323 work together under the system synchronization command, and achieve precise translational transmission through the first pulley 324, drive belt 325 and second pulley 326; the first guide rail 327 on the pulley base plate 321 provides a sliding reference for the intermediate baffle assembly 330, the end baffle 329 and the gripping position tail plate 331. The end cylinder 332 drives the end baffle 329 to adjust its position along the second guide rail 333, and cooperates with the lifting baffle 328 at the holding position to form a dummy box containing space that is suitable for the material specifications; the whole process relies on multi-servo axis time-synchronous control to ensure seamless connection between the lifting position and the trolley translation and baffle positioning actions, without action interference or position deviation.

[0069] Finally, the gripping cylinder 334 receives the synchronous linkage signal, drives the tail plate turntable 335 to rotate and drives the gripping tail plate 331 to flip open and close. After the vertical bagged material in the dummy box is fully arranged, the gripping tail plate 331 closes and seals synchronously. The servo synchronous control ensures that the locking timing is accurate, effectively ensuring that the vertical bagged material remains upright and does not tip over during the entire process of the trolley's transfer. Subsequently, the longitudinal vertical arrangement and transfer component 300 accurately transfers the neatly locked row of material to the rectangular coordinate gripping position. As the dummy box trolley completes the arrangement and transfers to the gripping position, and the rectangular coordinate mechanism grips the material downwards, the dummy box trolley moves down synchronously. With the continuous limiting protection of the side plate, the material is always kept in the closed dummy box space, effectively avoiding lateral tipping and stably completing the subsequent material picking and packing process.

[0070] In particular, the core innovation of this device, which uses a servo motor instead of a conventional motor, lies in its closed-loop synchronous control capability of servo speed, position, and angle. This enables multi-axis coordinated linkage of the lifting, translation, and adjustment axes, strictly constraining the sequence and positional accuracy of each mechanism's actions. This prevents material skewing, misalignment, jamming, and deviation caused by asynchronous mechanical movements. This servo synchronous control architecture is a key protected feature of this patent. Simultaneously, all flaps and baffles have rounded edges, and the precision guide rail assembly clearance ensures smooth and unobstructed material sliding and conveying. The synchronous control using a servo motor significantly ensures that the material will not tip over during the entire packing process, a key requirement protected by this patent.

[0071] In particular, the entire machine mechanism has a fixed logical sequence of actions: after the dummy box is ready, the servo lifts and supports the material, then the servo moves and aligns the material, the rear baffle limits and shapes the material, and finally the tail plate closes and locks the material synchronously; the fixed and movable ends of each adjustable baffle and flipping component move synchronously under the drive of the servo synchronous signal to ensure that the dummy box is symmetrical in the left and right and front and back.

[0072] In particular, the opening, closing, and resetting of the flaps and baffles follow a fixed sequence, and the timing of opening, closing, and retraction is precisely controlled by the servo synchronous timing, further improving the regularity of the vertical bagged material arrangement and the stability of the transfer.

[0073] Specifically, the machine achieves multi-specification adaptation through adjustable guide rails, quick-change components, and servo synchronous adjustment: the first guide rail 327, the second guide rail 333, and the third guide rail 336 are all linear guide rails, which enable stepless adjustment of the spacing between each baffle; the intermediate baffle assembly 330 consists of an intermediate plate 337 and a side plate 338, and the lower part forms a quick-change structure through a dummy box quick-change bottom plate 339, a quick-change platform 340, and a quick-change side pressure plate 341, which is locked by an adjustable handle 342 and positioned by a reset pin 343. When changing specifications, only the intermediate plate 337 needs to be replaced; at the same time, relying on servo synchronous control, it can accurately adapt to vertical bagged materials of different heights, lengths, and arrangement spacings, achieving rapid adjustment of length, width, and height in multiple dimensions, and is compatible with the production of vertical packaging boxes of multiple specifications.

Two first guide rails (327) are arranged parallel to each other along the material conveying direction on the pulley base plate (321). The first guide rail (327) is provided with an mounting plate, which is connected to the drive belt. The translation dummy box is set on the mounting plate. The trolley motor drives the pulley to rotate, thereby driving the mounting plate and the translation dummy box on it to move back and forth along the first guide rail (327) through the drive belt. The lifting platform (310) includes a lifting platform linear slide rail (318), a drive pulley (314), a driven pulley (316), and a lifting platform motor. The lifting platform linear slide rail (318) is arranged vertically. The drive pulley (314) and the driven pulley (316) are arranged sequentially along the lifting platform linear slide rail (318). A synchronous belt (315) is connected between the drive pulley (314) and the driven pulley (316). A tensioning pulley (317) is provided on one side of the synchronous belt (315). The pulley base plate (321) of the translation trolley is set on the lifting platform linear slide rail (318) and connected to the synchronous belt (315). The drive pulley (314) is connected to the lifting platform motor. The lifting platform motor drives the drive pulley (314) to rotate, thereby driving the pulley base plate (321) of the translation trolley to move up and down along the lifting platform linear slide rail (318) through the synchronous belt (315).

10. A case packing machine, characterized in that: It includes a packing robot and one or two automatic pre-packing mechanisms for vertically arranged bags as described in any one of claims 1-9. The packing robot is located above the material packing gripping position at the output end of the slotted conveyor, and a material stacking robot is located above the material stacking position at the input end of the slotted conveyor. When there are two automatic pre-packing mechanisms for vertically arranged bags, the two slotted conveyors are symmetrically arranged with their output ends facing inwards and opposite each other. The packing robot is positioned above the material grabbing position at the output end of the two slotted conveyors. Each slotted conveyor is equipped with a material stacking robot at its input end. The two automatic pre-packing mechanisms for vertically arranged bags share one packing robot.
