Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a novel tissue box packaging machine and several related mechanisms within the tissue box packaging machine. Background Technology

[0002] After facial tissues (standard rectangular shape with different sizes, hereinafter referred to as tissue boxes) are produced, manufacturers stack and package multiple tissue boxes into small tissue boxes (usually one small tissue box contains 6-12 tissue boxes) according to consumer purchasing habits, for easy carrying by consumers. Furthermore, to facilitate large-scale transportation, multiple small tissue boxes are often stacked and packaged into large tissue boxes, significantly reducing the number of handling operations at each transportation transfer point. The main equipment used for stacking and packaging multiple small tissue boxes into large tissue boxes is a tissue box packaging machine.

[0003] Currently, the conventional design concept of tissue box packaging machines is as follows: First, ensure that the small tissue box packaging units are vertically arranged according to their length (i.e., the length of the longest side of the small tissue box packaging unit) before entering the tissue box packaging machine. Then, multiple small tissue box packaging units are stacked horizontally twice (i.e., multiple small tissue box packaging units are stacked once in the horizontal X direction, and then the stacked tissue box packaging units are stacked once in the horizontal Y direction) to form a unit to be packaged. Then, the unit to be packaged is placed into a pre-waited packaging bag in a horizontal movement and moved to the sealing operation table to form a tissue box package to be sealed. Finally, the tissue box package to be sealed on the sealing operation table is sealed to form a tissue box package.

[0004] During the preliminary research and development of the tissue box packaging machine, the applicant of this invention summarized and found that the existing tissue box packaging machines mainly have the following technical problems.

[0005] First, the small tissue box units need to be uprighted before entering the large tissue box machine. Currently, the small tissue box units are manually flipped up according to their length to be vertically arranged. Therefore, the uprighting process requires at least one operator, which not only increases labor costs, but also makes it easy to place the small tissue box units in the wrong direction, affecting the normal operation of the large tissue box machine.

[0006] Secondly, existing tissue box pouch machines only have a horizontal stacking function. The tissue box pouches produced by such machines are relatively thin (the thickness of the tissue box pouch is equivalent to the length of the small tissue box pouch, and the length and width of the tissue box pouch are determined by the corresponding number of horizontal stacks. Due to the large number of horizontal stacks, the tissue box pouches are relatively flat). This means that when manually handling the tissue box pouches, it is necessary to hold the middle part of the tissue box pouch or hold both ends of the tissue box pouch at the same time. Otherwise, the tissue box pouches are prone to excessive bending and deformation and breakage.

[0007] Third, after the tissue box machine produces a tissue box unit, it needs to be manually removed from the machine's discharge table. However, when removing the tissue box unit from the discharge table, it is easy for it to bump into the machine, affecting work efficiency. Therefore, operators usually move the tissue box unit a short distance away from the machine on the discharge table before holding it and removing it from the discharge table. Summary of the Invention

[0008] To address the aforementioned shortcomings of existing large-package tissue dispensers, the applicant has designed and developed a novel large-package tissue dispenser. During the design and development process, based on the shape characteristics of the small tissue packaging units, the placement of these units and the stacking method of the large-package tissue dispenser were readjusted. Furthermore, innovative designs were implemented for all relevant mechanisms within the large-package tissue dispenser based on these changes.

[0009] The primary objective of this invention is to provide a tissue box packaging machine to solve the technical problem of inconvenient transportation caused by the thinness of the tissue box units produced by existing tissue box packaging machines. Furthermore, other objectives of this invention are to provide a material handling mechanism, a vertical stacking mechanism, a stacking mechanism, a packaging mechanism, and a discharging mechanism that can be applied in the aforementioned tissue box packaging machine.

[0010] In one aspect, a tissue box packaging machine is provided, comprising: a vertical stacking mechanism for vertically stacking tissue box units (small packages) conveyed to the tissue box packaging machine via an intermediate conveyor belt in a specific placement manner to form vertical stacking units; a horizontal stacking mechanism for horizontally stacking the vertical stacking units from the vertical stacking mechanism to form horizontal stacking units, wherein the horizontal stacking units are units to be packaged; a packaging mechanism for inserting the units to be packaged into packaging bags according to a set direction and moving them to a sealing operating table, and then sealing the tissue box units to be sealed on the sealing operating table to form tissue box packaging units; and a discharging mechanism for use in conjunction with the packaging mechanism to form the sealing operating table; wherein the tissue box units are composed of... A first rectangular body is formed by stacking and packaging multiple tissue box units. The length of the first rectangular body is greater than or equal to the width of the first rectangular body and greater than the thickness of the first rectangular body. The plane formed by the length and width of the first rectangular body is a first plane, the plane formed by the length and thickness of the first rectangular body is a second plane, and the plane formed by the width and thickness of the first rectangular body is a third plane. The tissue box units are placed on the middle conveyor belt in a specific manner. During the process from when the tissue box units are packaged into the tissue box units and output from the tissue box machines, the movement of the tissue box units only includes translation and does not involve flipping, and the second plane is always perpendicular to the vertical direction.

[0011] The aforementioned tissue box packaging machine can significantly reduce the differences between the length, width, and height of the tissue box unit, even making the tissue box unit nearly a cube. This eliminates the need to manually hold specific parts of the tissue box unit to prevent excessive bending and deformation during manual handling, thus facilitating operation and improving the transportation efficiency of the tissue box unit.

[0012] Secondly, a material-standing mechanism for a large tissue box packaging machine is provided, which is used to flip small tissue box units to a specific placement method and feed them into an intermediate conveyor belt. The intermediate conveyor belt is used to transport the small tissue box units to the large tissue box packaging machine in the specific placement method. The large tissue box packaging machine is used to stack multiple small tissue box units into packaging units and package the packaging units into large tissue box units. The small tissue box packaging unit is a first rectangular body formed by stacking and packaging multiple tissue box units. It includes: a receiving trough, one side of the receiving trough opening is provided with a material guide wall and the other side is provided with a directional flipping structure opposite to the material guide wall; an upper conveying mechanism, which is provided with... Above the receiving trough, a tissue box unit is used to transport the tissue box unit in a first placement manner to the opening of the receiving trough; a lower conveying mechanism is set at the bottom of the receiving trough and used to transport the tissue box unit in the receiving trough, which has been flipped to a second placement manner, to the middle conveyor belt; wherein, when the tissue box unit is transported to the opening of the receiving trough in the first placement manner, the side of the tissue box unit near the drop guide wall falls down along the drop guide wall, while the side of the tissue box unit near the directional flipping structure is blocked by the directional flipping structure, thereby causing the tissue box unit to be flipped to the second placement manner and fall onto the lower conveying mechanism.

[0013] The second aspect of the material-standing mechanism mentioned above, through its ingenious design, can automatically flip the tissue box units to a specific placement position and send them into the intermediate conveyor belt, saving the labor costs of the material-standing process and eliminating the production abnormality that may easily result in the tissue box units being placed in the wrong direction when manually standing the material.

[0014] Thirdly, a vertical palletizing mechanism for a large tissue box machine is provided. This mechanism is used to vertically palletize small tissue box units conveyed to the large tissue box machine via an intermediate conveyor belt in a specific placement manner, forming vertical palletizing units. The large tissue box machine is used to palletize multiple small tissue box units into units to be packaged and to package these units into a large tissue box unit. The unit to be packaged includes the vertical palletizing unit. The small tissue box unit is a first rectangular body formed by palletizing and packaging multiple tissue box units. It includes: a vertical palletizing input mechanism for receiving the small tissue box units conveyed to the machine via an intermediate conveyor belt in a specific placement manner. The system includes a tissue box unit conveyed via a specific method and a clamping and lifting mechanism for clamping and lifting the tissue box unit on the vertical stacking input mechanism. When a new tissue box unit appears below the clamped tissue box unit on the vertical stacking input mechanism, the clamped tissue box unit is released, thereby vertically stacking these tissue box units to form a vertical stacking unit. A vertical stacking output mechanism is connected to the vertical stacking input mechanism and conveys the vertical stacking unit.

[0015] The vertical stacking mechanism in the third aspect mentioned above enables the large tissue box machine to vertically stack the small tissue box units, thereby creating conditions for reducing the differences in length, width, and height between the large tissue box units.

[0016] Fourthly, a palletizing mechanism for a large tissue box machine is provided. The large tissue box machine is used to stack multiple small tissue box units into a packaged unit and package the packaged unit into a large tissue box unit. The small tissue box unit is a first rectangular body formed by stacking and packaging multiple tissue box units. It includes: a vertical palletizing mechanism for vertically palletizing the small tissue box units that are conveyed to the large tissue box machine by an intermediate conveyor belt in a specific placement manner to form a vertical palletizing unit; and a horizontal palletizing mechanism for horizontally palletizing the vertical palletizing units from the vertical palletizing mechanism to form a horizontal palletizing unit, wherein the horizontal palletizing unit is a packaged unit.

[0017] The fourth aspect of the palletizing mechanism mentioned above combines vertical and horizontal palletizing mechanisms, thereby significantly reducing the differences in length, width, and height between the units to be packaged, and ultimately greatly reducing the differences in length, width, and height between the large tissue box units, even making the tissue box unit nearly a cube. This way, when manually handling the tissue box units, it is not necessary to specifically hold certain parts of the tissue box unit to avoid excessive bending and deformation, thus improving the transportation efficiency of the tissue box units.

[0018] Fifthly, a packaging mechanism for a large tissue box machine is provided. The large tissue box machine is used to stack multiple small tissue box units into a packaging unit and package the packaging unit into a large tissue box unit. The small tissue box unit is a first rectangular body formed by stacking and packaging multiple tissue box units. It includes: a packaging unit bagging mechanism for inserting the packaging unit into a packaging bag according to a set direction and moving it to a sealing operation table to form a large tissue box unit to be sealed; and a large tissue box unit sealing mechanism for sealing the large tissue box unit to be sealed on the sealing operation table to form a large tissue box unit. The package includes a tissue box unit pushing mechanism, used to move the sealed tissue box unit on the sealing operation table a certain distance along a set direction; the packaging unit bagging mechanism includes a lower positioning guide mechanism, an upper positioning guide mechanism, and a packaging unit pushing mechanism; the lower positioning guide mechanism includes a lower support guide plate and a lifting drive mechanism for the lower support guide plate; the upper positioning guide mechanism includes an upper positioning guide plate and a lifting drive mechanism for the upper positioning guide plate; the packaging unit pushing mechanism pushes the packaging unit to move in a set direction under the common guidance of the lower support guide plate and the upper positioning guide plate; when the packaging unit moves in a set direction under the common guidance of the lower support guide plate and the upper positioning guide plate, the packaging unit gradually fits into the lower support guide plate and the upper positioning guide plate. In the opened packaging bag, after the unit to be packaged is completely separated from the lower support guide plate and the upper positioning guide plate of the unit to be packaged, the unit to be packaged is completely inserted into the packaging bag and moved to the sealing operation table to form a large tissue box unit to be sealed; the tissue box unit pushing mechanism includes a reciprocating drive mechanism for driving the lower positioning guide mechanism and / or the upper positioning guide mechanism of the unit to be packaged to move in a set direction, thereby pushing the tissue box unit to continue to move a distance in the set direction through the lower support guide plate and / or the upper positioning guide plate of the unit to be packaged.

[0019] The packaging mechanism described in the fifth aspect above can drive the tissue box unit to continue moving a certain distance along a set direction by driving the lower support guide plate and / or the upper positioning guide plate of the unit to be packaged. This pushes the tissue box unit away from the tissue box machine by a certain distance, preventing the tissue box unit from hitting the tissue box machine when it is manually removed from the sealing table. It also eliminates the need for operators to move the tissue box unit a certain distance away from the tissue box machine on the discharge table, reducing workload and improving work efficiency.

[0020] Sixthly, a discharging mechanism for a large tissue box machine is provided, which is used in conjunction with the packaging mechanism of the large tissue box machine to form a sealing operating table. The large tissue box machine is used to stack multiple small tissue box units into packaging units and package the packaging units into a large tissue box unit. The small tissue box unit is a first rectangular body formed by stacking and packaging multiple tissue box units. The packaging mechanism is used to insert the packaging units into packaging bags according to a set direction and move them to the sealing operating table, and then seal the large tissue box units to be sealed on the sealing operating table to form a large tissue box unit. It includes: a discharging table, which serves as a sealing operating table and includes a sealing operating table surface and a support for the sealing operation. The sealing operation table surface support structure includes: a tissue box unit limiting plate installed above the sealing operation table surface with a position adjustable bidirectionally along the length of the sealing operation table surface; a limiting plate position adjustment telescopic cylinder comprising a cylinder body and a telescopic rod, the cylinder body being installed under the sealing operation table surface via a slide rail, and the telescopic rod being connected to the tissue box unit limiting plate along the length of the sealing operation table surface; a cylinder body position adjustment screw rotatably installed under the sealing operation table surface and set along the length of the sealing operation table surface, the cylinder body position adjustment screw being connected to a rotary drive device; and a cylinder body position adjustment nut adapted to and fixedly connected to the cylinder body, the nut being fitted with the cylinder body position adjustment screw.

[0021] The discharge mechanism of the sixth aspect mentioned above can adjust the position of the limit plate of the tissue box unit over a wide range by adjusting the position of the limit plate telescopic cylinder and the position of the cylinder body screw, so that one or more tissue box units can be placed on the discharge table at the same time as needed.

[0033] The present invention will now be clearly and completely described in conjunction with the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention in conjunction with the accompanying drawings, it should be particularly noted that:

Other related terms and units can be reasonably interpreted based on the relevant content provided in this specification.

[0037] Figure 1 This is a schematic diagram of the overall structure of a tissue box packaging machine according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the material-standing mechanism of a tissue box making machine according to an embodiment of the present invention. Figure 9 This is a schematic diagram illustrating the movement process of the small tissue box unit in a large tissue box machine according to an embodiment of the present invention. Figure 1 , Figure 2 and Figure 9 As shown, the tissue box packaging machine itself includes a vertical stacking mechanism 13, a horizontal stacking mechanism 14, a packaging mechanism 15, and a discharging mechanism 16.

[0038] When the tissue box machine is in use, the entrance of the vertical stacking mechanism 13 is connected to the vertical material handling mechanism 11 through the intermediate conveyor belt 12.

[0039] The uprighting mechanism 11 is used to flip the tissue paper package unit 2 to a specific placement position and feed it into the intermediate conveyor belt 12. This process occurs during... Figure 9 At workstation #1 marked in the middle.

[0040] The intermediate conveyor belt 12 is used to transport the small tissue pack unit 2 to the large tissue pack machine in this specific placement manner. This process occurs during... Figure 9 At workstation #2 marked in the text.

[0041] The vertical stacking mechanism 13 is used to vertically stack the small tissue pack units 2, which are conveyed to the large tissue pack machine via the intermediate conveyor belt 12 in a specific placement manner, to form vertical stacking units 3. This process occurs during... Figure 9 At workstation #3 marked in the text.

[0042] The horizontal palletizing mechanism 14 is used to horizontally palletize the vertical palletizing units 3 from the vertical palletizing mechanism 13 to form a horizontal palletizing unit 4, which is the unit to be packaged. This process occurs during... Figure 9 At workstation #4 marked in the text.

[0043] The packaging mechanism 15 is used to insert the unit to be packaged into the packaging bag according to a set direction and move it to the sealing operation table 161, and then seal the large tissue box unit to be sealed on the sealing operation table 161 to form a large tissue box unit. This process occurs during Figure 9 At workstation #5 marked in the diagram, the unloading mechanism 16 is used in conjunction with the packaging mechanism 15 to form a sealing worktable 161.

[0044] Among them, the tissue box unit 2 is a first rectangular body formed by stacking and packaging multiple tissue boxes 21 (see Figure 9 The length of the first rectangle is greater than or equal to the width of the first rectangle and greater than the thickness of the first rectangle.

[0045] In this embodiment, the length of the first rectangle is 460mm, the width is 180mm, and the thickness is 120mm. The tissue box unit 2 is composed of six tissue box units 21 stacked and packaged, each tissue box unit 21 having dimensions of 230mm × 120mm × 60mm. Therefore, the length of the first rectangle is equivalent to twice the length of a tissue box unit 21, the width is equivalent to three times the height of a tissue box unit 21, and the thickness is equivalent to the width of a tissue box unit 21.

[0046] If we define the plane formed by the length and width of the first rectangle as the first plane, the plane formed by the length and thickness of the first rectangle as the second plane, and the plane formed by the width and thickness of the first rectangle as the third plane; then: after the tissue box unit 2 is flipped to a specific placement position and fed into the intermediate conveyor belt 12, until the tissue box unit 2 is packaged into the tissue box unit and output from the tissue box machine, the movement of the tissue box unit 2 only includes translation and does not involve flipping, and the second plane is always perpendicular to the vertical direction (see...). Figure 9 ).

[0047] The traditional design of a large tissue box packaging machine is as follows: First, ensure that the small tissue box units are vertically arranged according to their length as they enter the large tissue box packaging machine (the purpose of this design is obviously to maximize the thickness of the large tissue box units, and also to allow more small tissue box units to be stacked in the subsequent two horizontal stacking operations). Then, the multiple small tissue box units are stacked horizontally twice (i.e., multiple small tissue box units are stacked once in the horizontal X direction, and then the stacked tissue box units are stacked once in the horizontal Y direction) to form units to be packaged. Then, the units to be packaged are placed into pre-waited packaging bags in a horizontal movement and moved to the sealing operation table to form large tissue box units to be sealed. Finally, the large tissue box units to be sealed on the sealing operation table are sealed to form large tissue box units. Although the small tissue packs are vertically arranged according to their length and then horizontally stacked in the large tissue pack machine, the large tissue packs produced are still relatively thin and flat due to the large number of small tissue packs being stacked horizontally. This means that when manually handling the large tissue packs, it is necessary to hold the middle part of the tissue pack or both ends of the tissue pack at the same time; otherwise, the tissue packs are prone to excessive bending and deformation, and may break.

[0048] The inventors of this invention adopted the following design approach: First, adjust the posture of the small tissue box unit 2 as it enters the large tissue box machine to ensure that the second plane of the small tissue box unit 2 is perpendicular to the vertical direction (this eliminates the need to adjust the width of the intermediate conveyor belt 12 while ensuring the stability of the vertical stacking unit 3 during subsequent vertical stacking, preventing the vertical stacking unit 3 from collapsing); second, combine the aforementioned vertical stacking mechanism 13 with the aforementioned horizontal stacking mechanism 14, thereby greatly reducing the differences between the length, width, and height of the large tissue box unit, and even making the large tissue box unit nearly a cube. Thus, when manually handling the large tissue box unit, it is not necessary to specifically hold certain parts of the large tissue box unit to avoid excessive deformation, thereby facilitating operation and improving the transportation efficiency of the large tissue box unit.

[0049] like Figure 9 As shown, in this embodiment, the large tissue box unit consists of six smaller tissue box units 2, each with dimensions of 480mm × 460mm × 360mm. This size is ideal for manual handling of the large tissue box unit, allowing the operator to hold it from any direction without deformation. The inventors have discovered that although there are various standard sizes for the tissue box units 21, similar results can be achieved by using the tissue box packaging machine of this invention.

[0050] The following descriptions, in conjunction with the accompanying drawings, will explain the material erection mechanism 11, the vertical stacking mechanism 13, the horizontal stacking mechanism 14, the packaging mechanism 15, and the material discharge mechanism 16.

[0051] Elevating Mechanism

[0052] Figure 2 This is a schematic diagram of the material-standing mechanism of a tissue box making machine according to an embodiment of the present invention. Figure 2 As shown, the material handling mechanism 11 is used to flip the tissue box unit 2 to a specific placement mode and feed it into the intermediate conveyor belt 12. The intermediate conveyor belt 12 is used to transport the tissue box unit 2 to the tissue box machine in the specific placement mode. The tissue box machine is used to stack multiple tissue box units 2 into a unit to be packaged and package the unit to be packaged into a tissue box unit. The tissue box unit 2 is a first rectangular body formed by stacking and packaging multiple tissue boxes.

[0053] The material handling mechanism 11 specifically includes: a receiving trough, with a material guide wall 111 on one side of the trough opening and a directional flipping structure 112 opposite to the material guide wall on the other side; an upper conveying mechanism, located above the receiving trough and used to convey the tissue box unit 2 to the trough opening in a first placement manner; and a lower conveying mechanism, located at the bottom of the receiving trough and used to convey the tissue box unit that has been flipped to a second placement manner in the receiving trough to the intermediate conveyor belt; wherein, when the tissue box unit 2 is conveyed to the trough opening in the first placement manner, the side of the tissue box unit 2 near the material guide wall 111 falls downward along the material guide wall 111, while the side of the tissue box unit 2 near the directional flipping structure 112 is blocked by the directional flipping structure, thereby causing the tissue box unit 2 to be flipped to the second placement manner and fall onto the lower conveying mechanism.

[0054] In this embodiment: in the first placement method, the first plane is perpendicular to the vertical direction, and the third plane is perpendicular to the conveying direction of the upper conveying mechanism; in the second placement method, the second plane is perpendicular to the vertical direction, and the third plane is perpendicular to the conveying direction of the lower conveying mechanism.

[0055] Furthermore, from the time the tissue box unit 2 is flipped to the second placement position until it is packaged into the tissue box unit and output from the tissue box machine, the movement of the tissue box unit only involves translation and does not involve flipping.

[0056] In this embodiment, the intermediate conveyor belt 12 constitutes the lower conveying mechanism. In addition, the upper conveying mechanism is the output mechanism of the tissue box packaging machine, which is used to package multiple tissue boxes into tissue box units 2.

[0057] In this embodiment, the upper edge of the material guide wall 111 is also provided with a flared opening to guide the tissue box unit 2 and guide the tissue box unit 2 into the receiving groove.

[0058] In this embodiment, the directional flipping structure 112 specifically includes a directional flipping rod, the length direction of which is parallel to the conveying direction of the upper conveying mechanism. Furthermore, the directional flipping structure 112 also includes a receiving trough opening width adjustment mechanism for adjusting the distance between the directional flipping rod and the material drop guide wall. In this embodiment, the directional flipping rod is mounted on one side of the receiving trough via a bracket and together with the material drop guide wall forms the opening of the receiving trough; the receiving trough opening width adjustment mechanism is installed between the directional flipping rod and the bracket; the receiving trough opening width adjustment mechanism includes a horizontal support cantilever that is integrally connected to the directional flipping rod and perpendicularly arranged therefrom, and the horizontal support cantilever is telescopically connected to the bracket.

[0059] The distance between the directional flipping rod and the material drop guide wall can be adjusted by the material receiving groove opening width adjustment mechanism. In this way, the distance between the directional flipping rod and the material drop guide wall can be adjusted according to the size of the tissue box unit 2, so that the tissue box unit 2 can flip in the set manner.

[0060] The aforementioned material-standing mechanism 11 has a simple structure. Through clever design, it can automatically flip the tissue box unit 2 to a specific placement position and send it into the intermediate conveyor belt 12, saving the labor cost of the material-standing process and eliminating the production abnormality risk of incorrect placement of the tissue box unit 2 due to manual material standing.

[0061] Vertical palletizing mechanism

[0062] Figure 3 This is a schematic diagram of the vertical stacking mechanism of a tissue box packaging machine according to an embodiment of the present invention. Figure 3 As shown, the vertical stacking mechanism 13 is used to vertically stack the tissue box units 2 that are conveyed to the tissue box machine in a specific placement manner via the intermediate conveyor belt 12 to form a vertical stacking unit 3. The tissue box machine is used to stack multiple tissue box units 2 into a unit to be packaged and package the unit to be packaged into a tissue box unit. The unit to be packaged includes the vertical stacking unit. The tissue box unit is a first rectangular body formed by stacking and packaging multiple tissue box units.

[0063] The vertical palletizing mechanism 13 specifically includes: a vertical palletizing input mechanism 131, used to receive the tissue box unit 2 conveyed by the intermediate conveyor belt 12 in a specific placement manner, and to continue to convey the tissue box unit 2 in the specific placement manner; a clamping and lifting mechanism 132, used to clamp and lift the tissue box unit 2 on the vertical palletizing input mechanism 131, and then release the clamped tissue box unit when a new tissue box unit appears below the clamped tissue box unit on the vertical palletizing input mechanism 131, so that these tissue box units are vertically palletized to form a vertical palletizing unit 3; and a vertical palletizing output mechanism 133, used to connect with the vertical palletizing input mechanism 131 and to convey the vertical palletizing unit 3.

[0064] In this embodiment, the vertical palletizing input mechanism 131 and the vertical palletizing output mechanism 133 are the same conveying device. Specifically, the vertical palletizing input mechanism and the vertical palletizing output mechanism adopt a belt conveyor. The width of the belt conveyor is the same as that of the intermediate conveyor belt 12.

[0065] In this embodiment, a retractable blocking mechanism 134 is also provided between the vertical palletizing input mechanism 131 and the vertical palletizing output mechanism 133. When the retractable blocking mechanism 134 extends, it prevents the tissue box units on the vertical palletizing input mechanism 131 from entering the vertical palletizing output mechanism 133. When the retractable blocking mechanism 134 retracts, it allows the vertical palletizing units on the vertical palletizing input mechanism to enter the vertical palletizing output mechanism. Specifically, the retractable blocking mechanism 134 is a telescopic cylinder installed on the side of the vertical palletizing input mechanism 131. The retractable blocking mechanism 134 can effectively prevent the tissue box units on the vertical palletizing input mechanism 131 from entering the vertical palletizing output mechanism 133 before the vertical palletizing units 3 are formed.

[0066] In this embodiment, the clamping and lifting mechanism 132 includes a gantry 1321 mounted on the vertical stacking input mechanism. The gantry 1321 is driven to move up and down by a gantry lifting device 1322. Each side of the gantry 1321 is provided with a movable clamping plate 1323 and a clamping drive mechanism 1324 for driving the corresponding movable clamping plate 1323. Specifically, the gantry lifting device 1322 is a hydraulic cylinder; specifically, the clamping drive mechanism 1324 is a pneumatic cylinder.

[0067] Typically, the cylinder body of the hydraulic cylinder of the gantry lifting device 1322 is fixed on the frame of the tissue box machine. In addition, a guide mechanism can be provided between the gantry 1321 and the frame to guide the lifting movement of the gantry 1321.

[0068] The aforementioned vertical stacking mechanism 13 enables the large tissue box machine to vertically stack the small tissue box units 2, thereby creating conditions for reducing the differences in length, width, and height between the large tissue box units.

[0069] The main feature of the vertical palletizing mechanism 13 described above is that, since the running direction of the small tissue box unit 2 is not changed, the entire vertical palletizing mechanism 13 does not increase the width or floor space of the large tissue box machine. Therefore, this design facilitates modification of existing large tissue box machines, and at the same time, it allows for the sharing of more parts with existing large tissue box machines when manufacturing new ones, thereby greatly reducing the manufacturing cost of large tissue box machines.

[0070] Lateral palletizing mechanism

[0071] Figure 4 This is a schematic diagram of the transverse stacking mechanism of a tissue box packaging machine according to an embodiment of the present invention. Figures 3-4 , Figure 9 As shown, the horizontal palletizing mechanism 14 is used to horizontally palletize the vertical palletizing units 3 from the vertical palletizing mechanism 13 to form a horizontal palletizing unit 4, which is a unit to be packaged.

[0072] The horizontal palletizing mechanism 14 specifically includes: a horizontal palletizing input mechanism, which is used to connect with the vertical palletizing output mechanism 133 and transport the vertical palletizing unit 3 in the horizontal direction; a horizontal stacking mechanism, which is used to connect with the horizontal palletizing input mechanism and stack the vertical palletizing unit 3 transported by the horizontal palletizing input mechanism in the horizontal direction to form a horizontal palletizing unit 4; and a horizontal palletizing output mechanism, which is used to connect with the horizontal stacking mechanism and transport the horizontal palletizing unit 4.

[0073] In this embodiment, the horizontal palletizing input mechanism specifically includes a horizontal palletizing platform 141 disposed on one side of the vertical palletizing output mechanism 133 and a pushing mechanism 142 disposed on the other side of the vertical palletizing output mechanism 133. The pushing mechanism 142 is used to push the vertical palletizing unit 2 placed on the vertical palletizing output mechanism 133 into the horizontal palletizing platform 141 in a horizontal direction. Specifically, the pushing mechanism 142 includes a push plate 1421 and a push plate driving device 1422, and the push plate driving device 1422 is a telescopic cylinder.

[0074] In this embodiment, the transverse stacking mechanism specifically includes a positioning mechanism 143 and a stacking mechanism 144 disposed above the transverse stacking platform 141 and arranged opposite to each other in the horizontal transverse direction. The positioning mechanism 143 includes a positioning plate away from the pushing mechanism 142. The stacking mechanism 144 includes a stacking plate 1441 mounted on the frame above the transverse stacking platform 141 by a stacking drive mechanism. The stacking drive mechanism includes a mechanism for driving the stacking plate 1441 in the horizontal transverse direction (see...). Figure 4 The system includes a first drive mechanism 1442 for forward and backward movement and a second drive mechanism 1443 for driving the stacking plate 1441 up and down movement. Specifically, both the first drive mechanism 1442 and the second drive mechanism 1443 employ telescopic cylinders.

[0075] More specifically, the stacking plate 1441 is suspended on a telescopic bracket. The fixed part of the telescopic bracket is slidably mounted on a pair of guide rails on the frame above the transverse stacking platform 141. A telescopic cylinder serving as a second drive mechanism 1443 is installed above the telescopic bracket, and a telescopic cylinder serving as a first drive mechanism 1442 is installed on the frame above the transverse stacking platform 141. When the first drive mechanism 1442 is activated, the telescopic bracket drives the stacking plate 1441 to move horizontally along the guide rails. When the second drive mechanism 1443 is activated, the telescopic part of the telescopic bracket drives the stacking plate 1441 to move up and down.

[0076] In this embodiment, the horizontal palletizing output mechanism specifically includes a push-out mechanism 145 disposed above the horizontal palletizing platform 141 and reciprocating in the horizontal longitudinal direction. The push-out mechanism 145 is used to push the horizontal palletizing unit 4 placed on the horizontal palletizing platform 141 along the horizontal longitudinal direction (see...). Figure 4A horizontal palletizing platform 141 is introduced. The ejection mechanism 145 specifically includes a baffle, and a baffle driving mechanism is connected to the rear of the baffle. This baffle driving mechanism is the same as that of the existing tissue box machine.

[0077] In this embodiment, during the process from entering the vertical palletizing input mechanism 131 to being palletized into the horizontal palletizing unit 4 and then conveyed by the horizontal palletizing output mechanism, the movement of the tissue box unit 2 only involves translation and does not involve flipping, and the running path is U-shaped (see...). Figure 9 ).

[0078] The working principle of the aforementioned horizontal palletizing mechanism 14 is as follows: When the vertical palletizing unit 3 on the vertical palletizing output mechanism 133 moves to the front of the push plate 1421 of the push-in mechanism 142, the push plate driving device 1422 actuates to push the push plate 1421 to push the vertical palletizing unit 3. At this time, the stacking plate 1441 is lifted above the vertical palletizing unit 3 by the second driving mechanism 1443. Therefore, the stacking plate 1441 will not block the vertical palletizing unit 3 from entering the horizontal palletizing platform 141. Thus, the vertical palletizing unit 3 will be pushed into the horizontal palletizing platform 141 by the push plate 1421. After the vertical palletizing unit 3 enters the horizontal palletizing platform 141, the stacking plate 1441, driven by the first driving mechanism 1442 and the second driving mechanism 1443, pushes the vertical palletizing unit 3 towards the positioning plate of the positioning mechanism 143, gradually causing multiple vertical palletizing units 3 to be stacked sequentially behind the positioning plate in the horizontal direction, thereby forming the horizontal palletizing unit 4. Subsequently, the horizontal palletizing output mechanism pushes the horizontal palletizing unit 4 placed on the horizontal palletizing platform 141 out of the horizontal palletizing platform 141 in the horizontal longitudinal direction.

[0079] The main feature of the structural design of the above-mentioned horizontal palletizing mechanism 14 is that it enables the tissue box unit 2 to move only in translation and not in flipping during the process from entering the vertical palletizing input mechanism 131 to being palletized into the horizontal palletizing unit 4 and transported by the horizontal palletizing output mechanism, and the running path is U-shaped, thus minimizing the width and footprint of the tissue box machine.

[0080] Furthermore, since the horizontal palletizing input mechanism and the horizontal stacking mechanism are two independently operating devices, the process of the vertical palletizing unit 3 being pushed into the horizontal palletizing platform 141 and the process of the vertical palletizing unit 3 being stacked on the horizontal palletizing platform 141 can work together to improve the horizontal palletizing efficiency.

[0081] Packaging organization

[0082] Figure 5 This is a schematic diagram of the overall structure of the packaging mechanism of a tissue box packaging machine according to an embodiment of the present invention. Figure 6 This is a partial structural diagram of the packaging mechanism of a tissue box packaging machine according to an embodiment of the present invention. Figure 7 This is a partial structural diagram of the packaging mechanism of a tissue box packaging machine according to an embodiment of the present invention.

[0083] like Figure 5-7 As shown, the packaging mechanism 15 of the tissue box machine specifically includes: a bagging mechanism 151 for inserting the units to be packaged into a packaging bag according to a set direction and moving it to the sealing operation table 161 to form a tissue box unit to be sealed; a tissue box unit sealing mechanism 152 for sealing the tissue box unit to be sealed on the sealing operation table to form a tissue box unit; and a tissue box unit pushing mechanism for continuing to move the sealed tissue box unit on the sealing operation table 161 a certain distance along the set direction; wherein, the bagging mechanism 151 includes the units to be packaged. The package includes a lower positioning and guiding mechanism for the packaged unit, an upper positioning and guiding mechanism for the packaged unit, and a pushing mechanism for the packaged unit. The lower positioning and guiding mechanism for the packaged unit includes a lower support guide plate 1511 and a lifting drive mechanism 1513 for the lower support guide plate 1511, which drives the lower support guide plate 1511 to move up and down. The upper positioning and guiding mechanism for the packaged unit includes an upper positioning guide plate 1512 and a lifting drive mechanism 1514 for the upper positioning guide plate 1512, which drives the upper positioning guide plate 1512 to move up and down. The unit-to-be-packaged pushing mechanism is used to push the unit to be packaged in a set direction under the common guidance of the lower support guide plate 1511 and the upper positioning guide plate 1512 of the unit to be packaged. When the unit to be packaged moves in a set direction under the common guidance of the lower support guide plate 1511 and the upper positioning guide plate 1512 of the unit to be packaged, the unit to be packaged is gradually inserted into the packaging bag that is opened by the lower support guide plate 1511 and the upper positioning guide plate 1512 of the unit to be packaged. When the unit to be packaged is completely detached from the packaging bag... After the lower support guide plate 1511 of the unit is aligned with the upper positioning guide plate 1512 of the unit to be packaged, the unit to be packaged is completely inserted into the packaging bag and moved to the sealing operation table 161 to form a large tissue box unit to be sealed. The tissue box unit pushing mechanism includes a reciprocating drive mechanism 1515 for driving the lower positioning guide mechanism and / or the upper positioning guide mechanism of the unit to be packaged to move in a set direction, thereby pushing the tissue box unit to continue to move a distance in the set direction through the lower support guide plate 1511 and / or the upper positioning guide plate 1512 of the unit to be packaged.

[0084] In this embodiment, the bagging mechanism for the unit to be packaged has a frame structure composed of multiple guide rails. The multiple guide rails include a first guide rail pair 1516, a second guide rail pair 1517, and a third guide rail pair 1518. The first guide rail pair 1516 includes a pair of horizontal guide rails distributed on both sides of the lower part of the frame structure and relatively fixed. The second guide rail pair 1517 includes a pair of horizontal guide rails distributed on both sides of the upper part of the frame structure and relatively fixed. The third guide rail pair 1518 includes a pair of vertical guide rails distributed on both sides of the frame structure and relatively fixed. The lower positioning guide mechanism for the unit to be packaged is installed at the lower part of the third guide rail pair. The lower support guide plate 1511 of the unit to be packaged is driven to move up and down under the guidance of the third guide rail pair by the lifting drive mechanism 1513. The upper positioning guide mechanism for the unit to be packaged is installed... Mounted on the upper part of the third guide rail pair 1518, the upper positioning guide plate 1512 of the unit to be packaged is driven to move up and down by the lifting drive mechanism 1514 under the guidance of the third guide rail pair 1518. The third guide rail pair 1518 is also installed on the first guide rail pair 1516 and the second guide rail pair 1517. The third guide rail is connected to the reciprocating drive mechanism 1515. The reciprocating drive mechanism 1515 drives the third guide rail to move under the guidance of the first guide rail pair 1516 and the second guide rail pair 1517, so that the lower positioning guide mechanism and the upper positioning guide mechanism of the unit to be packaged move along the set direction. Then, through the lower support guide plate 1511 and the upper positioning guide plate 1512 of the unit to be packaged, the tissue box unit is pushed to continue to move a distance along the set direction.

[0085] Specifically, the lifting drive mechanism 1513 for the lower support guide plate of the unit to be packaged, the lifting drive mechanism 1514 for the upper positioning guide plate of the unit to be packaged, and the reciprocating drive mechanism 1515 all adopt telescopic cylinders.

[0086] Specifically, the lifting drive mechanism 1513 for the lower support guide plate of the unit to be packaged includes a lower lifting seat, and the lower support guide plate 1511 of the unit to be packaged includes a left support guide plate and a right support guide plate respectively installed on the lower lifting seat. The distance between the left support guide plate and the right support guide plate is adjustable. This facilitates the adjustment of the width of the lower support guide plate 1511 of the unit to be packaged according to the size of the transverse stacking unit 4.

[0087] In addition, the lower support guide plate 1511 of the unit to be packaged also includes a base plate installed on the lower lifting seat and located between the left and right support guide plates. The height of the base plate is lower than the height of the left and right support guide plates, so as not to hinder the adjustment of the distance between the left and right support guide plates. The function of the base plate is to seal the gap between the left and right support guide plates and prevent the transverse stacking unit 4 from jamming.

[0088] Specifically, the lifting drive mechanism 1514 for the upper positioning guide plate of the unit to be packaged includes an upper lifting seat, and the upper positioning guide plate 1512 of the unit to be packaged includes a left positioning guide plate and a right positioning guide plate respectively installed on the upper lifting seat. The distance between the left positioning guide plate and the right positioning guide plate is adjustable. This facilitates the adjustment of the width of the upper positioning guide plate 1512 of the unit to be packaged according to the size of the transverse stacking unit 4.

[0089] Generally speaking, during the process of the bagging mechanism of the unit to be packaged putting the unit to be packaged into the packaging bag in the set direction and moving it to the sealing operation table 161, the height of the sealing operation table 161 is lower than the height of the lower support guide plate 1511 of the unit to be packaged.

[0090] In this embodiment, the tissue box unit sealing mechanism 152 includes a sealing machine 1521 disposed between the outlet of the bagging mechanism of the unit to be packaged and the sealing operation table 161, and a tissue box unit clamping mechanism 1522 disposed between the sealing machine 1521 and the sealing operation table 161.

[0091] Specifically, the tissue box unit clamping mechanism 1522 includes a lower clamping device located below the entrance of the sealing operation table and an upper clamping device located above the entrance of the sealing operation table. The tissue box unit clamping mechanism 1522 can clamp the tissue box unit to be sealed when the sealing machine 1521 is working, ensuring the sealing quality.

[0092] The working principle of the above-mentioned packaging mechanism 15 is as follows: The horizontal palletizing output mechanism pushes the horizontal palletizing unit 4 (the unit to be packaged) onto the lower support guide plate 1511 of the unit to be packaged (at this time, the height of the lower support guide plate 1511 of the unit to be packaged is controlled by the lifting drive mechanism 1513 of the lower support guide plate of the unit to be packaged, so that the horizontal palletizing unit 4 (the unit to be packaged) can just transition from the horizontal palletizing platform 141 to the lower support guide plate 1511 of the unit to be packaged). Subsequently, the packaging unit pushing mechanism (which can also be the ejection mechanism 145) pushes the packaging unit to move in a set direction under the common guidance of the lower support guide plate 1511 and the upper positioning guide plate 1512 of the packaging unit. When the packaging unit moves in a set direction under the common guidance of the lower support guide plate 1511 and the upper positioning guide plate 1512 of the packaging unit, the packaging unit is gradually inserted into the packaging bag (which is pre-inserted) that is opened by the lower support guide plate 1511 and the upper positioning guide plate 1512 of the packaging unit. When the packaging unit is completely separated from the lower support guide plate 1511 and the upper positioning guide plate 1512 of the packaging unit, the packaging unit is completely inserted into the packaging bag and just moves to the sealing operation table 161 to form a large package of tissue paper to be sealed. Then, the clamping mechanism 1522 of the tissue box unit to be sealed clamps the tissue box unit, and the sealing machine 1521 seals the tissue box unit. Afterwards, the heights of the lower support guide plate 1511 and the upper positioning guide plate 1512 of the unit to be packaged are adjusted by the lifting drive mechanism 1513 and the lifting drive mechanism 1514, respectively. The reciprocating drive mechanism 1515 drives the lower support guide plate 1511 and the upper positioning guide plate 1512 of the unit to be packaged forward, thereby pushing the tissue box unit to continue moving a distance along the set direction.

[0093] As can be seen, the aforementioned packaging mechanism 15 can drive the lower support guide plate and the upper positioning guide plate of the unit to be packaged to push the tissue box unit to continue moving a certain distance in the set direction, thereby pushing the tissue box unit away from the tissue box machine. This avoids the tissue box unit hitting the tissue box machine when it is manually removed from the sealing operation table. It also eliminates the need for operators to move the tissue box unit a certain distance away from the tissue box machine on the discharge table, reducing workload and improving work efficiency.

[0094] The frame structure of the bagging mechanism 151 for the unit to be packaged is ingeniously designed, which enables the bagging mechanism 151 for the unit to be packaged to be guided in multiple directions without affecting the movement of the unit to be packaged.

[0095] Discharge mechanism

[0096] Figure 8 This is a schematic diagram of the discharging mechanism of a large tissue box machine according to an embodiment of the present invention. Figure 8 As shown, the discharging mechanism 16 of the tissue box machine is used in conjunction with the packaging mechanism 15 of the tissue box machine to form a sealing operation table 161. The tissue box machine is used to stack multiple tissue box units into packaging units and package the packaging units into tissue box units. The tissue box unit is a first rectangular body formed by stacking and packaging multiple tissue box units. The packaging mechanism 15 is used to put the packaging units into the packaging bag according to the set direction and move them to the sealing operation table, and then seal the tissue box units to be sealed on the sealing operation table to form tissue box units.

[0097] The discharging mechanism 16 specifically includes: a discharging platform, which serves as a sealing operation platform 161 and includes a sealing operation platform surface and a sealing operation platform support structure 162 for supporting the sealing operation platform surface; a tissue pack unit limiting plate 163, which is installed above the sealing operation platform surface and whose position can be adjusted bidirectionally along the length direction of the sealing operation platform surface; a limiting plate position adjusting telescopic cylinder 164, which includes a cylinder body and a telescopic rod, the cylinder body being installed under the sealing operation platform surface via a slide rail, and the telescopic rod being connected to the tissue pack unit limiting plate 163 along the length direction of the sealing operation platform surface; a cylinder body position adjusting screw 165, which is rotatably installed under the sealing operation platform surface and set along the length direction of the sealing operation platform surface, and the cylinder body position adjusting screw 165 is connected to a rotary drive device; and a cylinder body position adjusting nut 166, which is adapted to the cylinder body position adjusting screw 165 and fixedly connected to the cylinder body.

[0098] Specifically, a bearing seat is provided under the sealing operation table surface, and the cylinder position adjusting screw 165 is mounted on the bearing seat through bearing engagement. Specifically, the rotary drive device adopts a rotary handle 166. Specifically, the sealing operation table surface support structure 162 has four adjustable height support feet respectively set under the four corners of the sealing operation table surface.

[0099] The aforementioned discharging mechanism 16 can adjust the position of the tissue box unit limit plate 163 over a wide range through the limit plate position adjustment telescopic cylinder 164 and the cylinder position adjustment screw 165, so that one or more tissue box units can be placed on the discharging platform at the same time as needed.

All other embodiments obtained by those skilled in the art based on the foregoing content of this specification without inventive effort should fall within the scope of the present invention.
