Description

Technical Field

[0001] This application relates to the technical field of packaging machinery, and more particularly to a linear case opener. Background Technology

[0002] With the increasing market demand for automated packaging, manual, rapid, and large-volume packaging methods are inevitably becoming obsolete. In the process of using cardboard boxes, the cardboard panels need to be unfolded, the bottom folded up, and then sealed with tape. Therefore, automated carton opening equipment has emerged. For example, Chinese patent CN118239071A discloses a novel carton opening machine, including a mounting frame, a paper bin assembly, a paper picking assembly, a bottom forming assembly, a conveying assembly, and a sealing mechanism assembly. A collaborative robot drives the suction unit to rotate 90 degrees to pick up the cardboard panels from the paper bin assembly. The bottom forming assembly and the conveying assembly work together to automatically fold up the bottom of the carton, and then the sealing mechanism assembly seals it with tape, achieving fully automated operation from opening to sealing. However, the existing technology has certain drawbacks: the bottom of the paper bin assembly is tilted, and there is no structure on the discharge side of the paper bin assembly to prevent the cardboard material from falling. Under the weight of the carton, there is a risk that the carton may easily tip over from the paper bin assembly and fall into the paper picking assembly. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a linear box opener that can solve the above-mentioned problems existing in the prior art.

[0009] A bottom sealing mechanism is connected to the side of the box bottom forming mechanism away from the box taking mechanism, and is used to seal the bottom of the box material with adhesive tape.

[0010] Optionally, the adjustment linkage assembly includes a first chain, a first sprocket, and a second sprocket. The first sprocket is fixedly connected to the first lead screw, and the second sprocket is fixedly connected to the second lead screw. The first chain drives the first sprocket and the second sprocket.

[0011] Optionally, the top limiting frame includes a lifting guide rail and a slider. A slider is fixedly connected to each of the two opposite sides of the upper pressure plate. Each slider is slidably mounted on a lifting guide rail, and the lifting of the upper pressure plate is guided by the lifting guide rail.

[0012] Optionally, the second threaded sleeve is fixedly connected to one of the sliders.

[0013] Optionally, the first lead screw or the second lead screw is driven by an adjustment component, which drives the first lead screw and the second lead screw to rotate synchronously, thereby adjusting the height of the stop rod and the upper pressure plate.

[0014] Optionally, the adjustment assembly includes a handwheel, a rotating shaft, a second chain, a third sprocket, and a fourth sprocket. The rotating shaft is rotatably mounted on one side of one of the lifting guide rails, the second lead screw is rotatably mounted on one side of the other lifting guide rail, the third sprocket is fixed to the rotating shaft, the fourth sprocket is fixed to the second lead screw, the second chain drives the third sprocket and the fourth sprocket, and the handwheel is fixedly connected to the end of the rotating shaft.

[0015] Optionally, the discharge side of the storage tank rack is provided with an upwardly protruding lower baffle plate, and the baffle rod and the lower baffle plate are used to block the upper and lower sides of the tank material, respectively.

[0016] Optionally, the box retrieval mechanism includes a mechanical base and a box opening component mounted on the mechanical base. The mechanical base is used to drive the box opening component to move between the box storage mechanism and the box bottom forming mechanism. The box opening component is used to retrieve the box material from the box storage rack and unfold the box material.

[0017] Optionally, the unpacking assembly includes a rotating base, an unpacking bracket, a first suction cup holder, a second suction cup holder, and an unpacking motor. The rotating base is mounted on the mechanical base, and the unpacking bracket is mounted on the rotating base, allowing the unpacking bracket to rotate. The first suction cup holder is fixedly mounted on the unpacking bracket, and the second suction cup holder is rotatably mounted on the unpacking bracket. The unpacking motor is connected to the second suction cup holder to drive the second suction cup holder to rotate.

[0018] Optionally, the bottom of the second suction cup frame is equipped with a rotating folding plate and a folding cylinder. The folding cylinder is connected to the rotating folding plate, and the rotating folding plate is rotated by the folding cylinder, so that the rotating folding plate can fold one bottom plate of the carton upward to form a shape.

[0019] The beneficial effects of this application are as follows: This utility model provides a linear carton opener, in which a baffle is provided on the discharge side of the carton storage mechanism. The baffle rod of the baffle can block the carton material, so as to avoid the problem of the carton falling freely from the carton storage mechanism when it is not being picked up by the carton picking mechanism. At the same time, the baffle structure of this solution is also provided with a first lead screw and a first threaded sleeve. The baffle rod is connected to the first threaded sleeve. The baffle rod can be raised and lowered by rotating the first lead screw. Therefore, during operation, the height of the baffle rod can be adjusted according to the size and specifications of the carton being processed, so that the baffle rod can play an effective material blocking function, while avoiding the baffle rod from obstructing the carton picking operation of the carton picking mechanism.

[0020] In addition, this solution also incorporates a top limiting frame in the bottom forming mechanism. When folding the bottom of the carton, the upper pressure plate restricts the top of the carton, preventing it from moving upwards during folding and ensuring the quality of the bottom fold. Similarly, the top limiting frame is equipped with a second lead screw and a second threaded sleeve. Rotation of the second lead screw adjusts the height of the upper pressure plate to accommodate cartons of different sizes. Importantly, this solution also uses an adjustment linkage assembly to link the first and second lead screws, allowing them to rotate synchronously. Therefore, when adjusting the machine according to carton dimensions, only one of the first or second lead screws needs to be rotated to simultaneously adjust the height of the stop bar and the upper pressure plate, simplifying the adjustment process and increasing efficiency.

[0032] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] With the increasing market demand for automated packaging, manual, rapid, and large-volume packaging methods are inevitably becoming obsolete. In the process of using cardboard boxes, the cardboard panels need to be unfolded, the bottom folded up, and then sealed with tape. Therefore, automated carton opening equipment has emerged. For example, Chinese patent CN118239071A discloses a novel carton opening machine, including a mounting frame, a paper bin assembly, a paper picking assembly, a bottom forming assembly, a conveying assembly, and a sealing mechanism assembly. A collaborative robot drives the suction unit to rotate 90 degrees to pick up the cardboard panels from the paper bin assembly. The bottom forming assembly and the conveying assembly work together to automatically fold up the bottom of the carton, and then the sealing mechanism assembly seals it with tape, achieving fully automated operation from opening to sealing. However, the existing technology has certain drawbacks: the bottom of the paper bin assembly is tilted, and there is no structure on the discharge side of the paper bin assembly to prevent the cardboard material from falling. Under the weight of the carton, there is a risk that the carton may easily tip over from the paper bin assembly and fall into the paper picking assembly.

[0036] To overcome the above technical problems, refer to Figure 1-8This embodiment provides a linear carton opener, including a carton storage mechanism 1, a carton retrieval mechanism 2, a carton bottom forming mechanism 3, and a bottom sealing mechanism 4. The carton storage mechanism 1 includes a carton rack 11 and a baffle rack 12. The baffle rack 12 is installed on the discharge side of the carton rack 11 and includes a first lead screw 122, a first threaded sleeve 123, and a baffle rod 121. The baffle rod 121 is fixedly connected to the first threaded sleeve 123, and the first threaded sleeve 123 is threaded onto the first lead screw 122. The carton retrieval mechanism 2 is connected to the discharge side of the carton storage mechanism 1 and is used to retrieve carton material from the carton rack 11 and unfold the carton material. The carton bottom forming mechanism 3 is connected to the side of the carton retrieval mechanism 2 away from the carton storage mechanism 1 and is used to fold the bottom of the unfolded carton material into shape. The carton bottom forming mechanism 3 includes a top... The limiting frame 33 includes an upper pressure plate 331, a second lead screw 332, and a second threaded sleeve 333. The upper pressure plate 331 is fixedly connected to the second threaded sleeve 333, and the second threaded sleeve 333 is sleeved on the second lead screw 332. An adjusting linkage component 5 is connected to the first lead screw 122 and the second lead screw 332. The adjusting linkage component 5 drives the first lead screw 122 and the second lead screw 332 to rotate synchronously, thereby driving the material stop bar 121 and the upper pressure plate 331 to rise and fall synchronously. The bottom sealing mechanism 4 is connected to the side of the box bottom forming mechanism 3 away from the box taking mechanism 2 and is used to seal the bottom of the box with adhesive tape.

[0037] Specifically, the carton includes four side panels, each with an upper cover and a lower cover connected to its top and bottom respectively. In the storage rack 11, the carton is compressed into a flat plate shape. The carton retrieval mechanism 2 takes out the cartons one by one from the storage rack 11 and transfers them to the bottom forming mechanism 3. During the transfer process, the carton retrieval mechanism 2 unfolds the side panels of the carton into a square shape. After being pushed into the bottom forming mechanism 3, the four lower covers at the bottom of the carton are folded upwards. Then, it is pushed into the bottom sealing mechanism 4 and sealed with transparent tape.

[0038] The bottom of the storage rack 11 is inclined, allowing the cartons placed on it to slide along the bottom of the rack 11 towards the discharge side track under their own weight, ensuring that the carton retrieval mechanism 2 can smoothly retrieve the cartons each time. The baffle rod 121 of the baffle rack 12 is horizontally set, and its height is generally adjusted to block the top cover of the carton, preventing the carton from tipping over and falling. During the process of the orientation mechanism clamping and retrieving the carton, the top cover of the carton will bend relative to the side panel, allowing the top cover to pass over the baffle rod 121 and be removed. Therefore, the baffle rod 121 is set at different heights for opening cartons of different sizes. In this solution, the first lead screw 122 is rotatably installed on one side of the storage rack 11, and the height of the baffle rod 121 can be adjusted up and down based on the cooperation structure between the first lead screw 122 and the first threaded sleeve 123.

[0039] When the bottom forming mechanism 3 folds the bottom cover of the carton upwards, it applies an upward force to the carton. Therefore, to ensure smooth folding, this solution includes a top limiting frame 33 in the bottom forming mechanism 3. The top limiting frame 33 includes an upper pressure plate 331, which precisely restricts the top surface of the carton, preventing the carton from moving upwards during folding and ensuring a smooth folding process. Similarly, the bottom sealing mechanism 4 also applies an upward force to the carton during the sealing process. Therefore, to ensure sealing quality, the upper pressure plate 331 can extend above the bottom sealing mechanism 4, similarly limiting the top surface of the carton during the sealing process. Furthermore, the height of the upper pressure plate 331 varies depending on the size of the carton being opened. Therefore, the second lead screw 332 is rotatably mounted on one side of the bottom forming mechanism 3. Based on the cooperative structure of the second lead screw 332 and the second threaded sleeve 333, the height of the upper pressure plate 331 can be adjusted vertically.

[0040] In summary, based on the linear carton opener of this embodiment, a baffle 12 is provided on the discharge side of the carton storage mechanism 1. The baffle rod 121 of the baffle 12 can block the carton raw material to prevent the carton from falling freely from the carton storage rack 11 under the action of the non-carton picking mechanism 2. At the same time, the baffle 12 structure of this solution is also provided with a first lead screw 122 and a first threaded sleeve 123. The baffle rod 121 is connected to the first threaded sleeve 123. The baffle rod 121 can be raised and lowered by rotating the first lead screw 122. Therefore, during operation, the height of the baffle rod 121 can be adjusted according to the size and specifications of the carton being processed, so that the baffle rod 121 can play an effective material blocking function, while avoiding the baffle rod 121 from obstructing the carton picking operation of the carton picking mechanism 2.

[0041] In addition, this solution also includes a top limiting frame 33 in the bottom forming mechanism 3. When folding the bottom of the carton, the upper pressure plate 331 can restrict the top of the carton, preventing it from moving upwards during the folding process and ensuring the quality of the bottom fold. Similarly, the top limiting frame 33 in this solution is equipped with a second lead screw 332 and a second threaded sleeve 333. The height of the upper pressure plate 331 can be adjusted by rotating the second lead screw 332 to accommodate cartons of different sizes. Importantly, this solution also uses an adjustment linkage assembly 5 to link the first lead screw 122 and the second lead screw 332, allowing them to rotate synchronously. Therefore, when adjusting the machine according to the carton specifications, only one of the first lead screw 122 or the second lead screw 332 needs to be rotated to simultaneously adjust the height of the stop bar 121 and the upper pressure plate 331, simplifying the adjustment operation and increasing the adjustment efficiency.

[0042] In one embodiment, reference is made to Figure 3The adjustment linkage component 5 includes a first chain, a first sprocket, and a second sprocket. The first sprocket is fixedly connected to the first lead screw 122, and the second sprocket is fixedly connected to the second lead screw 332. The first chain drives the first sprocket and the second sprocket.

[0043] The first lead screw 122 and the second lead screw 332 are rotated synchronously via chain drive, allowing for simultaneous adjustment of the height of the stop bar 121 and the upper pressure plate 331, simplifying the adjustment process. Chain drive is characterized by accurate transmission and high efficiency, ensuring precise height adjustment of the stop bar 121 and the upper pressure plate 331. Furthermore, the chain drive assembly occupies little space, making the overall structure of the box opener more compact and rational.

[0044] In one embodiment, the top limiting frame 33 includes a lifting guide rail 334 and a slider 335. A slider 335 is fixedly connected to each of the two opposite sides of the upper pressure plate 331. Each slider 335 is slidably mounted on a lifting guide rail 334, and the lifting and lowering of the upper pressure plate 331 is guided by the lifting guide rail 334.

[0045] Guided precisely by the lifting guide rail 334, the upper pressure plate 331 can accurately stop at the required height, thus ensuring the accuracy and consistency of processing cartons of different sizes. At the same time, the coordinated design of the lifting guide rail 334 and the slider 335 makes the upper pressure plate 331 more stable during lifting, reducing folding or sealing quality problems caused by offset and swaying.

[0046] In one embodiment, the second threaded sleeve 333 is fixedly connected to one of the sliders 335.

[0047] The second threaded sleeve 333 is directly fixed to one of the sliders 335, so that the force applied by the second threaded sleeve 333 during the lifting process is directly applied to the slider 335 rather than to the upper baffle. Since the slider 335 is slidably mounted on the lifting guide rail 334, its movement stability is better and the structural reliability is stronger. It can more smoothly transmit the lifting force to the upper baffle to drive the upper baffle to lift. Therefore, the structure of this solution has the advantage of high reliability.

[0048] In one embodiment, the first lead screw 122 or the second lead screw 332 is connected to an adjustment component. The adjustment component drives the first lead screw 122 and the second lead screw 332 to rotate synchronously, thereby adjusting the height of the stop rod 121 and the upper pressure plate 331.

[0049] Since the first lead screw 122 and the second lead screw 332 are linked together by the adjusting linkage component 5 in this solution, rotating either lead screw will simultaneously drive both lead screws to rotate. This solution achieves the simultaneous adjustment of the height of the stop rod 121 and the upper pressure plate 331 by connecting only one of the first lead screw 122 and the second lead screw 332 to the adjusting component, offering advantages such as simple structure and low cost. The adjusting component can be a manual or electric adjustment structure.

[0050] In one embodiment, the adjustment assembly includes a handwheel 337, a rotating shaft 338, a second chain 336, a third sprocket, and a fourth sprocket. The rotating shaft 338 is rotatably mounted on one side of one of the lifting guide rails 334, and the second lead screw 332 is rotatably mounted on one side of the other lifting guide rail 334. The third sprocket is fixed to the rotating shaft 338, and the fourth sprocket is fixed to the second lead screw 332. The second chain 336 drivesly connects the third sprocket and the fourth sprocket, and the handwheel 337 is fixedly connected to the end of the rotating shaft 338.

[0051] The second chain 336 drives the third sprocket and the fourth sprocket. The third sprocket is fixed on the rotating shaft 338, while the fourth sprocket is fixed on the second lead screw 332. The second lead screw 332 is rotatably mounted on one side of another lifting guide rail 334, realizing the power transmission from the handwheel 337 to the rotating shaft 338 and then to the second lead screw 332.

[0052] In specific setup, the first lead screw 122, the second lead screw 332, and the adjustment linkage component 5 can be installed on the wall side of the box opener, while the handwheel 337 and the rotating shaft 338 can be installed on the aisle side of the box opener. This allows the operator to easily operate the handwheel 337 from the aisle to adjust the machine. The complex mechanisms, such as the first lead screw 122, the second lead screw 332, and the adjustment linkage component 5, can be installed on a side that is not easily accessible to the operator, which can effectively prevent damage from external forces and avoid the problem of their complex structure hindering the operator's machine adjustment and maintenance work.

[0053] In one embodiment, the discharge side of the storage box rack 11 is provided with an upwardly protruding lower baffle plate 111, and the baffle rod 121 and the lower baffle plate 111 are respectively used to block the upper and lower sides of the box material.

[0054] The lower baffle plate 111 and the baffle rod 121 block and position the carton from the upper and lower sides respectively. This dual blocking mechanism allows the carton to be more stably confined on the storage rack 11. During the carton retrieval process, the upper and lower cover plates of the carton can be bent relative to the side panels, allowing the carton to be easily removed.

[0055] In one embodiment, reference is made to Figure 5The box retrieval mechanism 2 includes a mechanical base 21 and a box opening component 22 mounted on the mechanical base 21. The mechanical base 21 is used to drive the box opening component 22 to move between the box storage mechanism 1 and the box bottom forming mechanism 3. The box opening component 22 is used to take out the box material from the box storage rack 11 and unfold the box material.

[0056] During operation, the mechanical base 21 first moves the carton opening component 22 to the side near the carton storage mechanism 1. Then, the carton opening component 22 grabs a carton, and then the mechanical base 21 moves the carton opening component 22 to the bottom forming mechanism 3. During the transfer, the carton opening component 22 unfolds the side panel of the carton.

[0057] Optionally, the mechanical base 21 includes an x-axis drive group 211 and a y-axis drive group 212. The x-axis drive group 211 can drive the box opening component 22 to move along the x-axis direction (i.e., the direction from the storage box mechanism 1 to the box bottom forming mechanism 3), thereby transferring the box opening component 22 between the storage box mechanism 1 and the box bottom forming mechanism 3. The y-axis drive group 212 can drive the box opening component 22 to move along the y-axis direction, so that the pointing direction can be aligned with the box bottom forming mechanism 3. Preferably, the x-axis drive group 211 and the y-axis drive group 212 are driven by a synchronous belt structure.

[0058] In one embodiment, reference is made to Figure 6 The unpacking assembly 22 includes a rotating base 221, an unpacking bracket 222, a first suction cup bracket 223, a second suction cup bracket 224, and an unpacking motor 225. The rotating base 221 is mounted on the mechanical base 21, and the unpacking bracket 222 is mounted on the rotating base 221, allowing the unpacking bracket 222 to rotate via the rotating base 221. The first suction cup bracket 223 is fixedly mounted on the unpacking bracket 222, and the second suction cup bracket 224 is rotatably mounted on the unpacking bracket 222. The unpacking motor 225 is connected to the second suction cup bracket 224 to drive the second suction cup bracket 224 to rotate.

[0059] Specifically, suction cups are respectively provided on the first suction cup frame 223 and the second suction cup frame 224. During the suction operation, the first suction cup frame 223 and the second suction cup frame 224 are kept facing the same direction towards the box material storage mechanism 1, and the suction cups on the first suction cup frame 223 and the second suction cup frame 224 respectively adhere to two adjacent side panels of the carton; after the carton is removed, the carton opening motor 225 drives the second suction cup frame 224 to rotate 90° relative to the first suction cup frame 223, so that the two side panels of the carton that are adhered are perpendicular to each other, and the carton opening is completed at this time; during the unfolding of the carton, the rotating base 221 drives the carton opening bracket 222 and the structure installed on it to rotate 90°, so that the first suction cup frame 223 is located in the direction parallel to the x-axis, and the second suction cup frame 224 is located on the side of the carton away from the bottom forming mechanism 3, so that the unfolded carton can be smoothly pushed into the bottom forming mechanism 3.

[0060] Based on the unpacking mechanism of this embodiment, the entire unpacking and unfolding process is automated, which greatly improves production efficiency and accuracy.

[0061] In one embodiment, reference is made to Figure 7-8 The bottom forming mechanism 3 includes a conveying component 31 and a folding component 32. The conveying component 31 includes two conveyor belts arranged in opposite directions. During the conveying process, the unfolded carton is clamped between the two conveyor belts for conveying. The folding assembly 32 includes a guide folding plate 321 and two side guide folding rods 322 installed on both sides of the guide folding plate 321. The bottom of the carton has four lower cover plates, with lower cover plate one and lower cover plate three facing each other, and lower cover plate two and lower cover plate four facing each other. During the process of the carton being brought into the bottom forming mechanism 3, lower cover plate one first contacts the guide folding plate 321, which pushes lower cover plate one to fold upward. As the carton continues to be brought in, lower cover plate two and lower cover plate four will contact the side guide folding rods 322 on both sides respectively, and the two side guide folding rods 322 will gradually guide lower cover plate two and lower cover plate four to fold upward. Therefore, by using the folding assembly 32, the folding of lower cover plate one, lower cover plate two and lower cover plate four can be realized during the carton conveying process.

[0062] To achieve the folding of the lower cover plate three, refer to Figure 6 In one embodiment, a rotating folding plate 226 and a folding cylinder 227 are installed at the bottom of the second suction cup frame 224. The folding cylinder 227 is connected to the rotating folding plate 226. The rotating folding plate 226 is rotated by the folding cylinder 227, so that the rotating folding plate 226 can fold a bottom plate of the carton upward to form a shape.

[0063] Specifically, the bottom of the side panel of the carton adsorbed by the second suction cup frame 224 corresponds exactly to the lower cover plate three. In this solution, a rotating folding plate 226 and a folding cylinder 227 are directly set at the bottom of the second suction cup frame 224. After the carton is unfolded, the folding cylinder 227 drives the rotating folding plate 226 to rotate. The rotating folding plate 226 can then fold the lower cover plate three upwards. Combined with the subsequent folding component 32, the folding of the four lower cover plates of the carton can be achieved.

[0064] The bottom sealing mechanism 4 is connected to the rear end of the folding assembly 32. Preferably, the conveying assembly 31 extends above the bottom sealing mechanism 4, so that the conveying assembly 31 can smoothly push the carton through the bottom sealing mechanism 4.
