Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, and in particular to a side-opening and sealing device. Background Technology

[0002] Cardboard boxes are the most common type of packaging product. They are made by cutting, creasing, folding, and binding or gluing cardboard. For ease of storage and transport, cardboard boxes are typically flat and stacked. Opening a cardboard box involves unfolding the flat box to create a three-dimensional structure, making it easier to place items inside and complete the packaging process.

[0003] In some packaging factories, the opening of cardboard boxes and the packing of goods are mostly done manually. While this allows for the smooth opening of boxes and the placement of goods inside, manual labor is inefficient. Therefore, automated packaging equipment has gradually emerged on the market, enabling the automatic completion of tasks such as opening cardboard boxes, filling goods, and sealing. For example, Chinese utility model patent CN213292850U discloses a carton opening machine. A first suction cup group and a second suction cup group are respectively attached to two adjacent sides of a flat carton. The first suction cup group moves one side of the carton horizontally, while the second suction cup group rotates the other side of the carton 90 degrees. In other words, by folding the two adjacent sides of the flat carton, the carton is opened, thus creating a three-dimensional structure. The opening method described above involves squeezing the two sides of the carton to open it. During the opening process, the carton completes the opening action after being subjected to considerable pressure. However, if the carton is damp or the cardboard is thin and therefore soft, the carton is prone to deformation after being subjected to pressure, and the location and direction of the deformation are uncontrollable, easily leading to opening failure.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned problems and provide a side-opening and sealing device, the technical solution of which is as follows:

[0006] A side-opening and sealing device, configured with a frame-type rack providing multiple mounting positions, further includes:

[0007] A box storage area for storing stacks of flat cardboard boxes;

[0008] A box-retrieving mechanism is mounted on the frame to pick up cartons stored in the box magazine. The box-retrieving mechanism includes a linear module arranged along the X-axis. The first end of the linear module is located above the box magazine, and the second end extends outside the box magazine. An adsorption frame is provided on the linear module and driven by it in a linear direction. Two sets of first suction cup assemblies, each consisting of several suction cups, are provided on the adsorption frame and correspond to two adjacent surfaces of the cartons.

[0009] The box opening mechanism is mounted on the frame and located below the box retrieval mechanism. It includes a transfer unit and a box opening unit mounted on the transfer unit and driven by the transfer unit to reciprocate along the Y and Z axes. The box opening unit includes a horizontal frame and a vertical frame, which are arranged perpendicularly to each other. A second suction cup assembly composed of several suction cups is mounted on the horizontal frame. When the second suction cup is in contact with the suction frame, the second suction cup assembly corresponds to one of the first suction cup assemblies and is staggered with the other first suction cup assembly.

[0017] Furthermore, the unpacking unit is also equipped with a spacing adjustment component, which includes:

[0018] The movable block includes two movable blocks that slide along the length of the cross frame. The second suction cup assembly is evenly distributed on the two movable blocks. The two movable blocks are respectively disposed at both ends of the cross frame. The vertical frame is fixedly mounted on one of the movable blocks.

[0019] The adjustment drive device includes an adjustment screw rotatably connected to the crossbeam, with threads having different directions at both ends of the adjustment screw, two movable blocks threadedly connected to the two ends of the adjustment screw, and an adjustment motor fixedly mounted on the crossbeam and drivenly connected to the adjustment screw.

[0020] Furthermore, the second drive unit includes a drive motor fixedly mounted on the mounting plate, and a drive screw that is connected to the drive motor in a transmission manner. The drive screw is threadedly connected to the linkage plate and moves back and forth in a straight line as the drive screw rotates.

[0021] Furthermore, the flipping component includes:

[0022] A shaft is rotatably connected to the linkage plate, and one end of the shaft is connected to the unpacking unit;

[0023] A cam groove is formed vertically on the mounting plate;

[0024] A rocker arm, one end of which is fixedly connected to the other end of the shaft, and the other end of which is provided with a sliding end, which is slidably connected within the cam groove.

[0025] Furthermore, a sealing mechanism is also installed on the frame to fold and close the bottom of the carton after it has been opened. The sealing mechanism is located at the end of the transfer unit away from the carton picking mechanism.

[0026] Furthermore, the sealing mechanism is located directly below the end of the transfer unit away from the box-retrieving mechanism, and includes:

[0027] A front folding base frame, which is fixedly mounted on the machine frame;

[0028] The rear folding bottom assembly is arranged along the Y-axis on the side of the front folding bottom frame facing the transfer unit. It includes a folding bottom arm and a folding bottom cylinder. One end of the folding bottom arm is rotatably connected to the frame. The folding bottom cylinder is connected to the folding bottom arm via a connecting rod to drive the folding bottom arm to swing around the pivot towards or away from the front folding bottom frame.

[0029] The side folding bottom assembly includes two side folding plates located on both sides of the front folding bottom frame. The side folding bottom assembly includes a side folding plate rotatably connected to the frame at its upper end, and a side folding cylinder mounted on the frame and connected to the side folding plate via a linkage to drive the side folding plate to fold from bottom to top around a rotating shaft.

[0036] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0037] In the technical solution provided by this utility model embodiment, the linear module moves the suction rack toward the box storage direction, causing the two first suction cup assemblies to suction the flattened folded cardboard boxes located inside the box storage. It is worth noting that the first suction cup assembly is composed of several suction cups arranged in a matrix. After the cardboard boxes are folded flat, they can be easily stacked. Furthermore, after the cardboard boxes are folded, two adjacent surfaces of the cardboard box are simultaneously on the same side. When the two first suction cup assemblies simultaneously suction the two adjacent sides of the cardboard box, the flattened cardboard box will not have its other two sides fall downwards and deform, or be prematurely opened. After the box-picking mechanism corresponds to the box-opening mechanism, the box-opening unit moves toward the cardboard box picked up by the box-picking mechanism under the drive of the transfer unit, thereby causing the second suction cup assembly mounted on the crossbeam to suction the lower surface of the cardboard. At this time, the second suction cup assembly suctions one of the surfaces located on the lower side of the cardboard box. In this state, the second suction cup assembly and one of the surfaces... In the subsequent unpacking action, the first suction cup assembly corresponding to the second suction cup assembly is closed, and the suction frame moves towards the side of the closed first suction cup assembly under the drive of the linear module. At the same time, the unpacking unit moves downward under the drive of the transfer unit. At this time, the two surfaces of the folded carton located on the upper and lower sides and intersecting with each other are attracted and the carton can be opened during the above movement. After the carton is opened, since the carton is in a three-dimensional state, the side of the carton corresponding to the closed first suction cup assembly is in a vertical state and corresponds to the third suction cup assembly set on the vertical frame, and is attracted by the third suction cup assembly. At this time, the other first suction cup assembly can be closed, and the suction frame separates from the opened carton under the drive of the linear module, thereby completing the unpacking action. After the carton is opened, the two adjacent sides of the carton are attracted by the second and third suction cup assemblies on the unpacking unit, thereby ensuring that the carton remains in the open state and does not return to the folded state. The technical solution provided by this utility model allows for the adsorption of the diagonal corners of the cardboard box, enabling the box to be opened by pulling diagonally. This prevents the straight lines from being subjected to pressure and deformation, thus allowing the box to be opened smoothly even when it is damp and soft or made of thin cardboard. This reduces the probability of box opening failure and improves the reliability of box opening.

[0047] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0048] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0049] Furthermore, the use of terms such as "first" and "second" in the embodiments of this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0050] This utility model provides a side-opening and sealing device that can open a flat cardboard box from the side. During the opening process, the box-lifting mechanism 300 and the box-opening mechanism 400 work together to open the flat cardboard box diagonally, thus preventing the cardboard box from being squeezed and ensuring that the cardboard box can be opened smoothly without deformation during the opening process. It is suitable for opening cardboard boxes that are damp or soft or have thin cardboard, ensuring the integrity of the cardboard box after opening and reducing the possibility of deformation during the opening process.

[0051] like Figure 1-4 As shown in the figure, the side-opening and sealing device provided in this embodiment of the present invention is configured with a frame 100 that is frame-shaped and provides multiple installation positions, and also includes a box storage 200, a box retrieval mechanism 300, and a box opening mechanism 400. The box storage 200 is used to store flat cardboard boxes for stacking. The box retrieval mechanism 300 is mounted on the frame 100 and is used to pick up cardboard boxes stored in the box storage 200. The box retrieval mechanism 300 includes cardboard box modules 310 arranged along the X-axis. The first end of the cardboard box module 310 is located above the box storage 200, and the second end extends beyond the box storage 200. An adsorption rack 320 is provided on the cardboard box module 310 and driven by it in a linear direction. Two sets of adsorption racks 320 are provided on the adsorption rack 320, each corresponding to one of the two adjacent surfaces of the cardboard box. A first suction cup assembly 330, composed of suction cups, is mounted on the frame 100 and located below the box-retrieving mechanism 300. It includes a transfer unit 410 and a box-opening unit 420 mounted on the transfer unit and driven by the transfer unit 410 to reciprocate along the Y and Z axes. The box-opening unit 420 includes a horizontal frame 421 and a vertical frame 422, which are arranged perpendicularly to each other. A second suction cup assembly 423, composed of several suction cups, is mounted on the horizontal frame 421. When the second suction cups are in contact with the suction holder 320, the second suction cup assembly 423 corresponds to one of the first suction cup assemblies 330 and is staggered with the other first suction cup assembly 330. A third suction cup assembly 424, composed of several suction cups, is mounted on the vertical frame 422. In this embodiment, in order to facilitate the adsorption of cardboard located inside the box 200, a cylinder 301 is installed on the cardboard module 310. The adsorption rack 320 is connected to the cylinder 301 and can move back and forth in the vertical direction under the drive of the cylinder 301, thereby making it easier to adsorb cardboard.

[0052] During the carton retrieval process, the carton module 310 moves the suction rack 320 toward the carton storage 200, causing the two first suction cup assemblies 330 to suction the flattened, folded carton located within the carton storage 200. It is worth noting that the first suction cup assembly 330 is composed of several suction cups arranged in a matrix. After the carton is folded flat, it can be easily stacked. Furthermore, after the carton is folded, two adjacent surfaces of the carton are simultaneously on the same side. When the two first suction cup assemblies 330 simultaneously suction the two adjacent sides of the carton, the folding... After being folded and flattened, the carton will not deform due to the other two sides falling downwards or being opened prematurely. After the carton picking mechanism 300 corresponds to the carton opening mechanism 400, the carton opening unit 420 moves towards the carton picked up by the carton picking mechanism 300 under the drive of the transfer unit, so that the second suction cup assembly 423 mounted on the crossbeam 421 adheres to the lower surface of the cardboard. At this time, the second suction cup assembly 423 adheres to one of the surfaces located on the lower side of the carton. In this state, the second suction cup assembly 423 and one of the first suction cups... Corresponding to component 330, during the subsequent unpacking action, the first suction cup component 330, corresponding to the second suction cup component 423, is closed, and the suction holder 320 moves towards the side of the closed first suction cup component 330 under the drive of the carton module 310. Simultaneously, the unpacking unit 420 moves downwards under the drive of the transfer unit. At this time, the two overlapping surfaces of the folded carton are suctioned and can be opened during the aforementioned movement. After the carton is opened, since it is in a three-dimensional state, the closed first suction cup component... The corresponding side of the carton 330 is vertical and corresponds to the third suction cup assembly 424 set on the vertical frame 422, and is attracted by the third suction cup assembly 424. At this time, the other first suction cup assembly 330 can be closed, and the suction frame 320 is driven by the carton module 310 to separate from the opened carton, thereby completing the opening action. After the carton is opened, the two adjacent sides of the carton are attracted by the second suction cup assembly 423 and the third suction cup assembly 424 on the opening unit 420, thereby ensuring that the carton remains in the open state and does not return to the folded state. Through the technical solution provided by this utility model, the carton is attracted diagonally, so that the carton can be opened by pulling diagonally, so that the straight lines are not subjected to compression force and deformation. Therefore, even when the carton is damp and soft or made of thin cardboard, it can be opened smoothly, reducing the probability of carton opening failure and improving the reliability of carton opening.

[0053] like Figure 2 , 4As shown in Figure 5, the transfer unit in this embodiment comprises a mounting plate 411, a first drive unit 412, a linkage plate 413, and a second drive unit 414. The mounting plate 411 is vertically positioned and slidably connected to the frame 100 along the Y-axis. The first drive unit 412 is mounted on the frame 100 and is connected to the mounting plate 411, driving the mounting plate 411 to reciprocate along the Y-axis. The linkage plate 413 is slidably connected to the mounting plate 411 along the Z-axis, and the unpacking unit 420 is mounted on the linkage plate 413, driving the linkage plate 413 to reciprocate along the Z-axis. This structure enables the unpacking unit 420 to reciprocate along both the Y and Z axes. In this embodiment, the first drive unit 412 includes a motor mounted on the frame 100 and a synchronous belt (not shown in the figure) driven by the motor. The synchronous belt is fixedly connected to the mounting plate 411, so that when the motor drives the synchronous belt to move, it can pull the mounting plate 411 to move back and forth on the frame 100.

[0054] In this embodiment, to facilitate the installation of a flipping assembly 430 on the linkage plate 413 of the unpacking unit 420, the unpacking unit 420 is connected to the flipping assembly 430 and flips under the drive of the flipping assembly 430, so that the vertical frame is placed horizontally. Figure 4 As shown, the unpacking unit 420 can be flipped under the drive of the flipping component 430, so that the carton after opening is set in a vertical direction, that is, one of the openings of the carton faces downward, which makes it convenient to perform sealing operations in accordance with the sealing mechanism 500.

[0055] In order to better connect with the flipping assembly 430, the unpacking unit 420 also includes a base plate 425. The base plate 425 is connected to the flipping assembly 430 in a transmission manner, and the horizontal frame 421 is fixedly installed on the base plate 425, and the vertical frame 422 is installed on the horizontal frame 421.

[0056] Meanwhile, in order to enable the carton opening component to adapt to cartons of different sizes, a spacing adjustment component 426 is also provided in the carton opening unit 420, such as... Figure 5-6As shown, the spacing adjustment assembly 426 includes movable blocks 4261 and an adjustment drive device. The movable blocks 4261 include two that slide along the length of the crossbeam 421. A second suction cup assembly 423 is evenly distributed on the two movable blocks 4261, which are respectively located at both ends of the crossbeam 421. A vertical frame 422 is fixedly mounted on one of the movable blocks 4261. The adjustment drive device includes an adjustment screw 4263 rotatably connected to the crossbeam 421, with threads having different directions at both ends. The two movable blocks 4261 are threaded to both ends of the adjustment screw 4263. It also includes an adjustment motor 4264 fixedly mounted on the crossbeam 421 and driven by the adjustment screw 4263. To improve adjustment accuracy, a grating ruler or position sensor is also provided on the spacing adjustment assembly to detect the movement stroke of the movable blocks. The grating ruler or position sensor is connected to the adjustment motor via a signal connection. This system ensures the movement accuracy of the movable block, improving adjustment precision and repeatability. Notably, it enables signal communication between the grating ruler or position sensor and the PLC controller. When changing products, the carton size and product size are input directly on the touchscreen, and the PLC automatically controls the motor to adjust the dimensions. The grating ruler or position sensor then feeds back the position information, ensuring accuracy. In contrast, traditional methods, which directly install a disc encoder at the motor end or power input position, suffer from mechanical backlash errors, or after a collision, coupling slippage, or motor failure, resulting in insufficient movement at the end point. The grating ruler or position sensor uses origin pulse or distance resistance type, completely avoiding mechanical slippage or backlash. When there is a signal output but no position feedback, it can also provide an alarm indicating a motor malfunction, rather than directly causing a collision as in a semi-closed loop system, thus improving the equipment's safe production performance.

[0057] During the opening process of small cartons, the width of one side of the carton is relatively small. Therefore, the second suction cup assembly 423 mounted on the crossbar 421 may not fully cover the side of the carton. Thus, the second suction cup assembly 423 on the crossbar 421 needs to be adjusted so that all the suction cups on the second suction cup assembly 423 on the crossbar 421 can adhere to one surface of the carton. It is worth noting that when the width of the side of the carton is small, the suction cups on the third suction cup assembly 424 mounted on the vertical frame 422 will also not fully adhere to the surface of the carton. However, once all the suction cups of the second suction cup assembly 423 can adhere to the carton, the reliability of the carton being adhered to by the opening mechanism 400 can be guaranteed. The third suction cup assembly 424 is used to keep the carton in the open state. Therefore, by having some of the suction cups on the third suction cup assembly 424 adhere to one surface of the carton, the open state of the carton can be maintained. The adjusting motor 4264 drives the adjusting screw 4263 to rotate, thereby causing the two movable blocks 4261 to move relative to each other or in opposite directions, thereby adjusting the distance between the suction cups located on the two movable blocks 4261, so that the second suction cup assembly 423 can be adapted to cartons of different sizes.

[0058] In this embodiment, as Figure 4 As shown, the second drive unit 414 includes a drive motor 4141 fixedly mounted on the mounting plate 411, and a drive screw 4142 that is drively connected to the drive motor 4141. The drive screw 4142 is threadedly connected to the linkage plate 413 and moves linearly reciprocally as the drive screw 4142 rotates. By using the screw system as the second drive unit 414, the unpacking unit 420 can be made more stable and have higher precision during vertical movement.

[0059] In this embodiment, as Figure 5As shown, the flipping assembly 430 comprises a shaft 431, a cam groove 432, and a swing arm 433. The shaft 431 is rotatably connected to the linkage plate 413, and one end of the shaft 431 is connected to the unpacking unit 420. The cam groove 432 is vertically formed on the mounting plate 411. One end of the swing arm 433 is fixedly connected to the other end of the shaft 431, and the other end of the swing arm 433 is provided with a sliding end 4331, which is slidably connected within the cam groove 432. By using a cam structure as the flipping assembly 430, during the flipping process of the unpacking unit 420, the sliding end 4331 of the swing arm 433 slides along the trajectory of the cam groove 432, thereby causing the swing arm 433 to swing with the shaft 431 as the center, thus flipping the unpacking unit 420 driven by the shaft 431. This structure is simple, reliable, and low in cost. In other embodiments, the flipping component 430 may also be a motor mounted on the linkage plate 413. The motor is directly connected to the box opening unit 420 via a reducer, or the motor may be connected to the box opening unit via a synchronous belt / chain in a conventional manner, thereby enabling the box opening unit 420 to be flipped.

[0060] After the flipping component 430 flips the carton opening unit 420, the carton is set in a vertical direction, which makes it convenient for the sealing mechanism 500 to fold and close the bottom of the carton. The sealing mechanism 500 is also set on the frame 100, and the sealing mechanism 500 is set at the end of the transfer unit away from the carton picking mechanism 300.

[0061] like Figure 2 As shown, in this embodiment, the sealing mechanism 500 is located directly below the end of the transfer unit 410 away from the box-retrieving mechanism 300, and includes a front folding base frame 510, a rear folding base assembly 520, and a side folding base assembly 530. The folding base frame is fixedly mounted on the frame 100. The rear folding base assembly 520 is located along the Y-axis on the side of the front folding base frame 510 facing the transfer unit 410, and includes a folding base arm 521 and a folding base cylinder 522. One end of the folding base arm 521 is rotatably connected to the frame 100. The bottom folding cylinder 522 is connected to the bottom folding arm 521 via a connecting rod to drive the bottom folding arm 521 to swing around the pivot towards or away from the front bottom frame 510; the side bottom folding assembly 530 includes two respectively located on both sides of the front bottom frame 510. The side bottom folding assembly 530 includes a side folding plate 531 rotatably connected to the frame 100 at its upper end, and also includes a side folding cylinder 532 mounted on the frame 100 and connected to the side folding plate 531 via a connecting rod to drive the side folding plate 531 to fold from bottom to top around the pivot.

[0062] During the folding and sealing of the bottom of the carton, the carton is pre-flipped and then moved downwards, thus enabling it to cooperate with the sealing mechanism. The working process of the opening and sealing mechanisms provided in this embodiment is as follows:

[0063] 1. The first drive unit 412 and the second drive unit 414 drive the opening unit 420 to move, so that the opening unit 420 moves toward the front folding base frame 510 until the end of the front flap 01 of the carton (the flap facing the front folding base frame 510 is the front flap) comes into contact with the front folding base frame 510. The folding arm 521 swings under the drive of the folding cylinder 522, thereby moving the end of the rear flap 02 of the carton (the flap away from the front folding base frame 510 is the rear flap). At this time, the second drive unit 414 drives the opening unit to descend.

[0064] 2. After both the front flap 01 and the rear flap 02 are folded (more accurately, both flaps are folded at a relatively large angle), it is as follows: Figure 8 In the state shown, the second drive unit 414 drives the unpacking unit 420 to move downward again, causing the carton to move downward and completely fold the front flap 01 and the rear flap 02 so that they are closed at the bottom of the carton.

[0065] 3. At this time, the first drive unit 412 drives the unpacking unit 420 to move along the Y-axis until the flaps 03 on both sides of the carton correspond to the side folding bottom assembly 530. Then the first drive unit 412 stops. At this time, the side folding bottom assembly 530 folds the flaps 03 on both sides of the carton. The side folding cylinder 532 drives the side folding plate 531 to flip, thereby folding the flaps 03 on both sides of the carton and continuously increasing the folding angle to complete the sealing of the carton.

[0066] Through the above actions, the end of the flap can be turned. Since the flap is folded along the crease, the lever arm of the flap is relatively large during the process of packing the carton. Therefore, only a small amount of force is needed to complete the folding action of the flap, and the carton will not be deformed or crushed due to the applied turning force, thus ensuring the reliability of the lower flap closure.

[0067] like Figure 7As shown, this embodiment provides the specific structure of the box storage 200. The box storage 200 includes a protective panel assembly 210, guide columns 220, pallets 230, a lifting device 240, and a detection device 214. The protective panel assembly 210 includes a rear panel 211 and two corresponding side panels 212, which define a storage area 213 for placing and stacking cartons. The guide columns 220 include several arranged in a matrix and distributed in the storage area. Outside of area 213; pallet 230 is slidably connected to guide post 220 along its edge, and pallet 230 is at least partially located within storage area 213 to support carton stacking within storage area 213; lifting device 240 is fixedly mounted on frame 100 and is drively connected to pallet 230 to drive pallet 230 to reciprocate along guide post 220; detection device 214 is located at the upper end of rear plate 211 / side plate 212 and is signal connected to lifting device.

[0068] In this embodiment, the lifting device 240 can be composed of a motor and a transmission chain. The motor and the transmission chain are connected by a sprocket to form a transmission system, thereby driving the transmission chain to move. The transmission chain is fixedly connected to the bracket, so it can move back and forth along the guide column 220 to lift the carton, making it convenient for the carton retrieval mechanism 300 to pick up the carton. When the carton is lifted to the position corresponding to the detection device 214, the detection device 214 transmits a detection signal to the lifting device 240, thereby stopping the lifting device 240. At the same time, if the detection device 214 does not detect the carton, it means that the height of the carton is not high enough, making it difficult for the carton retrieval mechanism 300 to pick up the carton. The detection device 214 also transmits a detection signal to the lifting device 240 to make it operate to lift the carton.

[0069] For those skilled in the art, various other corresponding changes and modifications can be obtained based on the structure and principles disclosed in this utility model, and all such changes and modifications fall within the protection scope of this utility model.
