Description

Technical Field

[0001] This application relates to the technical field of toilet paper production equipment, and in particular to a toilet paper feeding device. Background Technology

[0002] The toilet paper production line in related technologies includes a toilet paper folding machine, a feeding device, and a toilet paper packaging machine. The toilet paper folding machine includes an unwinding roller, a folding device, and a toilet paper output conveyor belt. A roll of raw paper is mounted on the unwinding roller, which unwinds the raw paper roll. After passing through the folding device, the paper roll is cut into multiple sheets of toilet paper, and each sheet is folded independently. The folded toilet paper falls onto the toilet paper output conveyor belt, which transports the toilet paper. The feeding device includes a receiving impeller, a palletizing conveyor belt, and a transfer assembly. The receiving impeller receives the toilet paper conveyed from the toilet paper output conveyor belt. The gap between adjacent blades of the receiving impeller is sufficient to hold a toilet paper, thereby enabling the counting of toilet paper and the palletizing of a specified number of toilet paper sheets onto the palletizing conveyor belt. The palletizing conveyor belt transports the palletized toilet paper, and the transfer component transfers the toilet paper from the palletizing conveyor belt to the toilet paper packaging machine. The toilet paper packaging machine packages and seals the toilet paper to form the finished toilet paper product.

[0003] In related technologies, to facilitate the differentiation and transfer of each stack of toilet paper, multiple partitions are typically fixed at intervals on the palletizing conveyor belt. Adjacent partitions form receiving grooves, and a receiving impeller directs a specified number of toilet paper sheets into these grooves. Toilet paper sheets can be laid flat or vertically on the palletizing conveyor belt. Horizontal placement means the toilet paper sheets are parallel to the conveyor belt, while vertical placement means they are perpendicular to the conveyor belt.

[0004] For toilet paper stacked flat, a top pressure strip is fixedly connected above the palletizing conveyor belt. This top pressure strip limits the top side of each stack of toilet paper, while partitions limit one side of each stack. Since finished toilet paper products come in different quantities, such as 20, 30, or 50 sheets packaged into a single pack, the relatively fixed position of the top pressure strip makes it difficult to adjust and effectively limit the position of each stack. This can easily lead to loosening of the stacks during transport.

[0005] When toilet paper is stacked vertically, adjacent partitions limit the movement of each stack on both sides. The fixed spacing between partitions and the large number of partitions make it difficult to adjust the spacing. When producing different quantities and sizes of finished toilet paper, the toilet paper in the receiving slots is not tightly packed together after stacking. During transport on the palletizing conveyor belt, the position of the toilet paper on the conveyor belt becomes unstable, easily leading to some of the stacked toilet paper shifting or falling over.

[0006] Furthermore, regardless of whether the toilet paper is laid flat or vertically, when producing a small quantity of finished toilet paper (e.g., 20 sheets per pack), each compartment holds only a small number of toilet paper, reducing the amount of toilet paper loaded on the palletizing conveyor belt and thus reducing transportation efficiency. Summary of the Invention

[0007] In order to facilitate the adaptation and production of toilet paper of different quantities and specifications, improve the positional stability of toilet paper during transportation, and increase the loading capacity of stacked toilet paper, this application provides a toilet paper unloading device.

[0008] This application provides a toilet paper feeding device, which adopts the following technical solution: A toilet paper feeding device includes a frame, a paper receiving impeller, a paper receiving guide trough, a lifting mechanism, a pushing assembly, a palletizing conveyor, a baffle assembly, and a transfer mechanism; The receiving guide groove is connected to the frame. The paper receiving impeller is used to vertically drop the toilet paper into the receiving guide groove. The pushing component pushes the toilet paper to move in the receiving guide groove, so that the toilet paper moves to the palletizing conveyor. The lifting mechanism includes a lifting drive source, a lifting support plate, and an extension component, wherein the extension component is disposed on the lifting support plate; the lifting drive source drives the lifting support plate and the extension component to move up and down, thereby lifting multiple stacks of toilet paper in the receiving guide groove at intervals, such that the top sides of adjacent stacks of toilet paper are arranged in a concave-convex pattern and adjacent stacks of toilet paper abut against each other; the extension component is used to adjust the distance extending from the lifting support plate to change the number of toilet paper stacks lifted; The baffle assembly abuts against one end of the multiple stacks of toilet paper located on the palletizing conveyor, and the transfer mechanism removes the multiple stacks of toilet paper from the palletizing conveyor one by one.

[0009] By adopting the above technical solution, the lifting mechanism creates a concave-convex arrangement on the top sides of adjacent stacks of toilet paper, ensuring tight contact and improving transport stability. This effectively addresses the problems of loose contact, easy shifting, and tipping over between adjacent stacks of toilet paper in vertical stacking. The extension components allow for flexible adjustment of the number of toilet paper stacks lifted, enabling a single unit to adapt to the production needs of various quantities and specifications of toilet paper, thus improving equipment versatility. This application eliminates the partitions found in related technologies, allowing adjacent stacks of toilet paper to directly contact each other, increasing the loading capacity of toilet paper on the palletizing conveyor and improving transport efficiency.

[0010] Optionally, the pushing component includes a pushing drive source and a pushing plate, the pushing plate being connected to the pushing drive source, the pushing drive source driving the pushing plate to move, so that the pushing plate pushes the toilet paper to move on the receiving guide groove.

[0011] By adopting the above technical solution, the drive source drives the push plate to move directly, which realizes the stable pushing of toilet paper in the guide groove, so that the toilet paper moves from the receiving guide groove to the palletizing conveyor, improving the continuity of equipment operation.

[0012] Optionally, the extension component includes a telescopic plate and a connector, the telescopic plate being slidably connected to the lifting support plate, and the connector locking the relative position of the telescopic plate and the lifting support plate.

[0013] By adopting the above technical solution, the telescopic plate extends a certain distance from the lifting support plate, and then the relative position of the telescopic plate and the lifting support plate is locked with a connector, thus achieving precise adjustment and reliable locking of the lifting length. This enables rapid response to adjustment needs when producing different quantities and specifications of finished toilet paper products.

[0014] Optionally, the extension component includes a telescopic airbag connected to one side of the lifting support plate. The telescopic airbag is connected to an external air source and expands to adjust the distance it extends beyond the lifting support plate.

[0015] By adopting the above technical solution, the pneumatic expansion characteristics of the telescopic airbag are used to achieve stepless adjustment of the lifting length. The adjustment process does not require stopping the machine and has a rapid response, which improves the equipment's adaptability to different quantities and specifications of finished toilet paper products. At the same time, it simplifies the mechanical adjustment structure and reduces manufacturing and maintenance costs.

[0016] Optionally, the lifting support plate has an installation groove on one side, and the telescopic airbag is installed in the installation groove.

[0017] By adopting the above technical solution, the telescopic airbag is installed in the mounting groove, making the structure more compact.

[0018] Optionally, the transfer mechanism includes an insertion component and a clamping and moving component, the insertion component being inserted between adjacent stacks of toilet paper on the palletizing conveyor, and the clamping and moving component clamping a stack of toilet paper and removing it from the palletizing conveyor.

[0019] By adopting the above technical solution, the transfer mechanism adopts a two-step working mode of first inserting and separating and then clamping and removing, which effectively solves the problem that adjacent stacks of toilet paper are difficult to separate due to close contact, and realizes the accurate and stable transfer of the entire stack of toilet paper.

[0020] Optionally, the insertion assembly includes a movable component, an insertion drive source, an insertion tip, and a detection sensor; the movable component is disposed on the frame, and the insertion drive source and the detection sensor are disposed on the movable component; The moving component drives the insertion drive source and the detection sensor to move along the length of the multiple stacks of toilet paper. The detection sensor detects the change in its distance from the top of the toilet paper to determine the boundary position of adjacent stacks of toilet paper. The insertion drive source drives the insertion cone to insert between adjacent stacks of toilet paper.

[0021] By adopting the above technical solution, the boundary position between adjacent stacks of toilet paper is automatically identified by the detection sensor, realizing automatic positioning of the insertion position, providing a reliable positioning basis for subsequent separation and clamping, and improving the automation level of the equipment.

[0022] Optionally, the transfer mechanism further includes a separating component, which includes a separating drive source and a separating plate. The separating plate is connected to the separating drive source, which is disposed on the moving member. The moving member drives the separating drive source to move, and the separating drive source drives the separating plate to insert between adjacent stacks of toilet paper and separate the adjacent stacks of toilet paper.

[0023] By adopting the above technical solution, a separator component is added to the insertion component. The insertion of the separator piece achieves physical isolation between adjacent stacks of toilet paper, making it easier for the clamping and moving component to clamp the separated stack of toilet paper.

[0024] Optionally, the clamping and moving assembly includes a feeding moving component and a clamping component. The clamping component is disposed on the feeding moving component, and the feeding moving component drives the clamping component to move. The clamping component clamps a stack of toilet paper.

[0025] By adopting the above technical solution, the feeding moving part drives the clamping part to move, and the clamping part can clamp a stack of toilet paper, realizing the direct clamping and removal of the entire stack of toilet paper, improving the feeding speed and ensuring the stability of the clamping and removal process.

[0026] Optionally, the baffle assembly includes a limiting baffle and an end block, the end block being connected to the end of the palletizing conveyor; the limiting baffle is placed in the receiving guide groove, the limiting baffle abutting against the ends of multiple stacks of toilet paper located on the receiving guide groove, the limiting baffle being used to move along the receiving guide groove to the end of the palletizing conveyor; when the palletizing conveyor is filled with toilet paper, the limiting baffle and the end block are fixedly connected.

[0027] By adopting the above technical solution, the limiting baffle is first placed in the receiving guide groove, so that the limiting baffle abuts against the ends of the multiple stacks of toilet paper. At this time, the limiting baffle limits the ends of the multiple stacks of toilet paper, and the multiple stacks of toilet paper push the limiting baffle from the receiving guide groove to the end of the palletizing conveyor. When the palletizing conveyor is full of toilet paper, that is, when the ends of the multiple stacks of toilet paper reach the end of the palletizing conveyor, the limiting baffle is fixedly connected to the end stop block, thereby fixing the position of the limiting baffle.

[0028] In summary, this application includes at least one of the following beneficial effects: 1. This application uses a lifting mechanism to create a concave-convex arrangement on the top sides of adjacent stacks of toilet paper, which tightly abuts against each other. This effectively solves the problems of toilet paper not sticking together and easily shifting and falling over in the vertical placement method, thus improving transportation stability. At the same time, the expansion components allow for flexible adjustment of the number of toilet paper lifted, enabling this application to adapt to the production needs of various quantities and specifications of finished products, thereby improving equipment versatility and production efficiency. 2. This application uses a detection sensor to automatically identify the boundary position of adjacent stacks of toilet paper, and inserts and separates the adjacent stacks of toilet paper to facilitate the clamping and moving component to clamp a stack of toilet paper and unload it.

[0031] The following combination Figures 1 to 8 This application will be described in further detail.

[0032] Example 1:

[0033] Embodiment 1 of this application provides a toilet paper feeding device.

[0034] refer to Figure 1 and Figure 2 A toilet paper feeding device includes a frame 1, a receiving impeller 2, a receiving guide trough 3, a lifting mechanism 4, a pushing assembly 5, a stacking conveyor 6, a baffle assembly 7, and a transfer mechanism 8. The receiving guide trough 3 is fixedly connected to the frame 1. The folding machine in the previous process feeds single sheets of toilet paper onto the receiving impeller 2. The receiving impeller 2 rotates and places the toilet paper vertically onto the receiving guide trough 3. The receiving impeller 2 can count the number of toilet paper sheets, so that they can be stacked on the receiving guide trough 3 according to a predetermined number of sheets.

[0035] refer to Figure 2 The pushing component 5 includes a pushing drive source 51 and a pushing plate 52. The pushing drive source 51 is specifically a two-axis linear module. The body of the pushing drive source 51 is fixedly connected to the frame 1, and the output end of the pushing drive source 51 is fixedly connected to the pushing plate 52. The pushing drive source 51 can drive the pushing plate 52 to move horizontally and vertically. When the paper receiving impeller 2 stacks toilet paper on the receiving guide groove 3, the pushing drive source 51 moves the pushing plate 52 closer to the side of the stacked toilet paper, and then pushes the stacked toilet paper to move on the receiving guide groove 3.

[0036] refer to Figure 3and Figure 4 The lifting mechanism 4 includes a lifting drive source 41, a lifting support plate 42, and an extension component 43. The lifting drive source 41 is specifically an electric cylinder. The body of the lifting drive source 41 is fixedly connected to the frame 1, and the output end of the lifting drive source 41 is fixedly connected to the lifting support plate 42. The lifting drive source 41 can drive the lifting support plate 42 to move up and down, so that the lifting support plate 42 passes through the receiving guide groove 3.

[0037] refer to Figure 2 and Figure 3 When the pushing component 5 moves a stack of toilet paper above the lifting support plate 42, the lifting drive source 41 drives the lifting support plate 42 upward, causing the lifting support plate 42 to lift the stack of toilet paper. Subsequently, the pushing component 5 pushes the next stack of toilet paper to abut against the lifted toilet paper, and the lifting drive source 41 drives the lifting support plate 42 downward. The pushing component 5 continues to push the toilet paper, making the adjacent stacks of toilet paper fit more tightly and improving the situation where the height of the lifted toilet paper decreases.

[0038] refer to Figure 3 and Figure 4 The lifting mechanism 4 lifts the adjacent stacks of toilet paper at intervals, so that the top sides of the adjacent stacks of toilet paper have a concave-convex arrangement, and the adjacent stacks of toilet paper press against each other, thus keeping the top sides of the adjacent stacks of toilet paper in a concave-convex arrangement.

[0039] refer to Figure 3 and Figure 5 The extension component 43 includes a telescopic plate 431 and a connecting rod. The telescopic plate 431 is slidably connected to the lifting support plate 42. The connecting member 432 is specifically a bolt, which is threadedly connected to the lifting support plate 42 and abuts against the telescopic plate 431. The telescopic plate 431 is horizontally pulled out from one side of the lifting support plate 42, thereby adjusting the distance the telescopic plate 431 extends from the side of the lifting support plate 42. The connecting member 432 is then tightened to lock the relative position of the telescopic plate 431 and the lifting support plate 42. When the lifting drive source 41 drives the lifting support plate 42 to rise, it simultaneously drives the telescopic plate 431 to rise, so that the lifting support plate 42 and the telescopic plate 431 together lift the toilet paper. Because the distance the telescopic plate 431 extends from the side of the lifting support plate 42 can be adjusted, the number of toilet paper lifted can be adjusted, allowing this application to adapt to the production of products of different quantities and specifications.

[0040] refer to Figure 1 and Figure 6The palletizing conveyor 6 in this application includes a palletizing guide trough 61, which is fixedly connected to the frame 1 and communicates with the receiving guide trough 3. The baffle assembly 7 includes a limiting baffle 71 and an end stop 72, which is fixedly connected to the end of the palletizing guide trough 61 away from the receiving guide trough 3. When the toilet paper is first filled into the palletizing guide trough 61, the limiting baffle 71 is first placed in the receiving guide trough 3, so that the limiting baffle 71 abuts against the ends of multiple stacks of toilet paper. The pushing assembly 5 pushes the toilet paper on the receiving guide trough 3 to move gradually, and the multiple stacks of toilet paper push the limiting baffle 71 to move along the receiving guide trough 3 into the palletizing guide trough 61. When the limiting baffle 71 reaches the end of the palletizing guide trough 61, the palletizing guide trough 61 is now filled with toilet paper. The limiting baffle 71 and the end stop 72 are then fixedly connected by bolts. In other embodiments of this application, the palletizing conveyor 6 may also be a conveyor belt, which can assist in the movement of multiple stacks of toilet paper when the pushing component moves the multiple stacks of toilet paper.

[0041] refer to Figure 6 and Figure 7 The transfer mechanism 8 includes an insertion component 81, a clamping and moving component 83, and a separating component 82. The insertion component 81 includes a moving part 811, an insertion drive source 812, an insertion cone 813, and a detection sensor 814. The moving part 811 is specifically a linear module, and its body is fixedly connected to the frame 1. The detection sensor 814 is specifically a photoelectric sensor, and it is fixedly connected to the output end of the moving part 811. The detection sensor 814 is located above the toilet paper on the palletizing guide groove 61. The transmitter of the detection sensor 814 emits a light signal to the top side of the toilet paper, and the reflected light signal is received by the receiver of the detection sensor 814. The moving part 811 drives the detection sensor 814 to move linearly. Due to the concave and convex arrangement of the top sides of multiple stacks of toilet paper, the intensity of the reflected light signal changes. The detection sensor 814 can determine the boundary line between adjacent stacks of toilet paper based on the change in the intensity of the light signal.

[0042] refer to Figure 6 and Figure 7 The insertion drive source 812 is specifically a cylinder. The body of the insertion drive source 812 is fixedly connected to the output end of the moving part 811, and the moving end of the insertion drive source 812 is fixedly connected to the insertion tip 813. The moving part 811 can drive the insertion drive source 812 to move, and the insertion drive source 812 can drive the insertion tip 813 to move, so that the insertion tip 813 is inserted from the dividing line of adjacent stacks of toilet paper.

[0043] refer to Figure 6 and Figure 7The separating component 82 includes a separating drive source 821 and a separating plate 822. The separating drive source 821 is specifically a cylinder. The body of the separating drive source 821 is fixedly connected to the output end of the moving part 811, and the separating plate 822 is fixedly connected to the output end of the separating drive source 821. After the inserting cone 813 is inserted between adjacent stacks of toilet paper, the separating drive source 821 drives the separating plate 822 to move, so that the separating plate 822 is inserted from the dividing line of the adjacent stacks of toilet paper, and the separating plate 822 separates the adjacent toilet paper.

[0044] refer to Figure 6 The clamping and moving assembly 83 includes a feeding moving component 831 and a clamping component 832. The feeding moving component 831 specifically adopts a two-axis linear module, and the clamping component 832 specifically adopts a pneumatic gripper. The body of the feeding moving component 831 is fixedly connected to the frame 1, and the clamping component 832 is fixedly connected to the output end of the feeding moving component 831. The feeding moving component 831 can drive the clamping component 832 to move horizontally and vertically. The clamping component 832 can clamp a stack of separated toilet paper, thereby moving the stack of toilet paper from the palletizing guide trough 61 to the packaging machine conveyor belt of the next process, realizing the feeding of toilet paper.

[0045] refer to Figure 1 and Figure 7 When the clamping and moving component 83 removes a stack of toilet paper, the pushing component 5 pushes the toilet paper to move within the stacking guide groove 61. The separator 822 abuts against the end of the toilet paper and moves accordingly. When the end of the toilet paper abuts against the limiting baffle 71 again, the separator driving source 821 drives the separator 822 to reset.

[0046] refer to Figure 4 and Figure 5 The telescopic plate 431 can be horizontally pulled out from the lifting support plate 42, resulting in a height difference between the top side of the telescopic plate 431 and the top side of the lifting support plate 42. When the lifting drive source 41 drives the lifting support plate 42 and the telescopic plate 431 to lift a stack of toilet paper, a corresponding height difference also appears on the top side of the stack of toilet paper. This height difference is smaller than the height difference on the top side of adjacent stacks of toilet paper, which helps the detection sensor 814 to distinguish the boundary line of adjacent stacks of toilet paper.

[0047] The implementation principle of the toilet paper feeding device in Embodiment 1 of this application is as follows: the toilet paper from the previous process reaches the receiving impeller 2, which stacks the toilet paper onto the receiving guide groove 3. The driving source 51 drives the pushing plate 52 to move, so that the pushing plate 52 pushes the toilet paper to move on the receiving guide groove 3. When a predetermined number of toilet paper reach above the lifting support plate 42, the lifting driving source 41 drives the lifting support plate 42 and the telescopic plate 431 to lift the toilet paper. Then, the pushing component 5 makes the next stack of toilet paper come into contact with the lifted toilet paper. The lifting driving source 41 then drives the lifting support plate 42 and the telescopic plate 431 to descend. Then, the pushing component 5 continues to push the toilet paper to move, so that the top side of the multiple stacks of toilet paper is arranged with concave and convex patterns, which is beneficial for the detection sensor 814 to determine the boundary line of adjacent stacks of toilet paper based on the concave and convex patterns of the top side of the toilet paper. Subsequently, the insertion drive source 812 causes the insertion cone 813 to be inserted between adjacent stacks of toilet paper, and the separation drive source 821 causes the separator 822 to be inserted between adjacent stacks of toilet paper. The separator 822 separates the adjacent stacks of toilet paper. Finally, the clamping and moving assembly 83 clamps the separated toilet paper and moves it out of the palletizing guide groove 61.

[0048] Example 2:

[0049] Embodiment 2 of this application provides a toilet paper feeding device. The difference between Embodiment 2 and Embodiment 1 is that: refer to Figure 8 In this embodiment, the extension component 43 includes a telescopic airbag 433. A mounting groove is provided on the side wall of the lifting support plate 42, and the telescopic airbag 433 is installed in the mounting groove. The telescopic airbag 433 is connected to an external air source. When it is necessary to adjust the quantity and specifications of the finished toilet paper, gas is injected into the telescopic airbag 433 without stopping the machine. The telescopic airbag 433 expands and extends a certain distance from the side wall of the lifting support plate 42. The lifting drive source 41 can drive the lifting support plate 42 and the telescopic airbag 433 to jointly lift a predetermined number of toilet paper rolls.

[0050] refer to Figure 8 After the lifting support plate 42 and the telescopic airbag 433 jointly lift the toilet paper, the lifting drive source 41 drives the lifting support plate 42 and the telescopic airbag 433 to descend. During the descent, the telescopic airbag 433 contracts, which helps the pushing component 5 to push the next stack of toilet paper to press against the lifted toilet paper.

[0051] refer to Figure 8The telescopic airbag 433 expands and extends from one side of the lifting support plate 42, resulting in a height difference between the top side of the telescopic airbag 433 and the top side of the lifting support plate 42. When the lifting drive source 41 drives the lifting support plate 42 and the telescopic airbag 433 to lift a stack of toilet paper, a corresponding height difference also appears on the top side of the stack of toilet paper. This height difference is smaller than the height difference on the top side of adjacent stacks of toilet paper, which helps the detection sensor 814 to distinguish the boundary line of adjacent stacks of toilet paper.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
