[0002] With the increasing application of gluing machines at ever-faster speeds, the traditional manual paper collection process poses a significant challenge. The speed, durability, and accuracy of manual paper collection can no longer meet the demands of the current gluing machine market, greatly limiting the production efficiency of gluing machines.

[0003] Chinese patent application CN204137996U discloses an automated cardboard counting and stacking device, including a frame, a first conveying unit and a second conveying unit mounted on the frame; the feed end of the first conveying unit is fixed to the frame, and the discharge end is connected to a lifting mechanism that drives the discharge end of the first conveying unit to rise and fall; a fixed bracket is mounted on the first conveying unit; a counting sensor located above the first conveying unit and a stacking mechanism located below the first conveying unit are mounted on the fixed bracket; the second conveying unit is connected to the discharge end of the first conveying unit and is located below the first conveying unit; side baffles are mounted on both sides of the second conveying unit, and a stacking baffle perpendicular to the conveying direction is mounted in the conveying direction of the second conveying unit; the upper end of the stacking baffle is movably mounted on a guide rail and connected to a first cylinder. This patent achieves automated cardboard counting and stacking by setting a counting sensor and stacking baffles, but it cannot adapt to high paper feeding speed scenarios.

[0004] Therefore, how to achieve rapid paper counting and stacking in high paper feeding speed scenarios is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a fully automatic high-speed counting paper receiving machine and its paper transport direction control method.

[0006] The objective of this invention can be achieved through the following technical solutions: According to one aspect of the present invention, a fully automatic high-speed counting paper receiving machine is provided for paper counting; it includes a paper feeding and counting unit, a conveying buffer unit, a counting stacking unit, and a paper receiving output unit, wherein the paper feeding and counting unit includes a layer changing mechanism for changing the paper conveying direction, and the paper feeding and counting unit, the conveying buffer unit, the counting stacking unit, and the paper receiving output unit are connected end to end in sequence.

[0007] As a preferred technical solution, the paper feeding and counting unit includes a counting conveyor belt and a counting photoelectric sensor. The counting conveyor belt and the conveying buffer unit are connected end to end. The counting photoelectric sensor is arranged opposite to the counting conveyor belt. The layer changing mechanism is located at the connection between the counting conveyor belt and the conveying buffer unit.

[0008] As a preferred technical solution, the layer-changing mechanism includes a cylinder and an L-shaped swing arm, the swing arm and the cylinder are poweredly connected, and the swing arm is located at the connection between the counting conveyor belt and the conveying buffer section.

[0009] As a preferred technical solution, the buffer conveying unit includes a layered conveyor belt group composed of multiple conveyor belts, and the layered conveyor belt group is connected end to end with the paper feeding and counting unit.

[0010] As a preferred technical solution, the layered conveyor belt group includes an overlapping first conveyor belt and a second conveyor belt, wherein the first conveyor belt is located at the bottom and is flush with the counting conveyor belt.

[0011] As a preferred technical solution, the counting and stacking section includes a stacking frame, an annular guide rail, side baffles, and push rods. The annular guide rail is symmetrically arranged on the stacking frame, the push rods are spaced apart on the annular guide rail, and the side baffles are installed on both sides of the stacking frame.

[0012] As a preferred technical solution, the counting and stacking section further includes a rotating baffle and a paper-blocking rod, wherein the rotating baffle is disposed at the outlet end of the stacking frame and the paper-blocking rod is disposed at the inlet end of the stacking frame.

[0013] As a preferred technical solution, the counting stacking section includes multiple stacking stations, with adjacent push rods on the same annular guide rail forming a stacking station.

[0014] As a preferred technical solution, the paper receiving output section includes a paper receiving frame, a rear tapping rod cylinder assembly, a rubber-coated drive roller, and a guide plate. The rear tapping rod cylinder assembly and the rubber-coated drive roller are overlapped and installed at the inlet end of the paper receiving frame, and the guide plate is installed on the paper receiving frame and is arranged opposite to the rear tapping rod cylinder assembly and the rubber-coated drive roller.

[0015] According to another aspect of the present invention, a paper transport direction control method based on any of the above-described fully automatic high-speed counting paper receiving machines is provided, the method comprising: S1. Determine the number of layers in the transport buffer section; S2. Determine the tilt angle of each layer based on the number of layers; S3. The counting stacking section counts the number of papers passing through and changes the tilt angle of the layer-changing mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention has a replacement layer mechanism in the conveying buffer section, which eliminates the need to stop and wait during the paper counting and stacking station switching process. The buffer section receives the continuous paper from upstream and guides the paper to the idle stacking station through the replacement layer. This fundamentally eliminates the efficiency loss caused by the forced shutdown of traditional paper receiving machines due to full stacking, realizes continuous and uninterrupted high-speed paper receiving operation, and thus improves efficiency.

[0017] 2. This invention dynamically adjusts the tilt angle of the swing arm based on real-time counting by point-to-point photoelectric sensors, enabling each batch of paper to be automatically distributed to the corresponding layer of the conveyor belt without manual intervention. This ensures a balanced load distribution across all stacking stations, coordinated overall cycle time, and optimal high-speed operation.

[0018] 3. The present invention is equipped with an L-shaped swing arm, which can provide a flat paper bearing surface at different swing angles, so that the swing arm can play a dual role of guiding and supporting the paper when it is in position.

[0019] 4. The layered conveyor belt assembly of the present invention is designed to be multi-layered, which further expands the buffer capacity. When the counting and stacking section needs to spend a long time sorting or outputting paper stacks, the buffer section can continuously accept the paper coming from upstream, avoiding being forced to slow down due to insufficient buffer.

[0020] 5. This invention features a circular track and push rods. When the push rods move, they push out the stacked papers. The push rods are arranged at fixed intervals to form multiple independent stacking stations, enabling seamless connection between the stacking stations. The entire machine always maintains full-load operation, significantly increasing output per unit time and completely eliminating downtime caused by station switching. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] Example 1 like Figures 1 to 3 As shown, a fully automatic high-speed counting paper receiving machine is used for counting paper 17; it includes a paper feeding and counting unit 1, a conveying buffer unit 2, a counting stacking unit 3, and a paper receiving and output unit 4. The paper feeding and counting unit 1 includes a layer changing mechanism for changing the conveying direction of the paper 17. The paper feeding and counting unit 1, the conveying buffer unit 2, the counting stacking unit 3, and the paper receiving and output unit 4 are connected end to end in sequence.

[0024] In this embodiment, the fully automatic high-speed counting paper receiving machine of the present invention is mainly used to automatically count, stack and receive paper 17 in a fixed quantity.

[0025] Along the transport direction of the paper 17, the paper feeding and counting unit 1, the transport buffer unit 2, the counting and stacking unit 3, and the paper receiving and output unit 4 are connected end to end.

[0026] like Figure 4 As shown, the paper feeding and counting unit 1 includes a counting conveyor belt and a counting photoelectric sensor 15. The counting conveyor belt and the conveying buffer unit 2 are connected end to end. The counting photoelectric sensor 15 is arranged opposite to the counting conveyor belt. The layer changing mechanism is located at the connection between the counting conveyor belt and the conveying buffer unit 2.

[0027] The layer-changing mechanism includes a cylinder 14 and an L-shaped swing arm 13. The swing arm 13 and the cylinder 14 are poweredly connected. The swing arm 13 is located at the connection between the counting conveyor belt and the conveying buffer section 2.

[0028] The buffer conveying unit 2 includes a layered conveyor belt group composed of multiple conveyor belts, and the layered conveyor belt group is connected end to end with the paper feeding and counting unit.

[0029] The layered conveyor belt assembly includes an overlapping first conveyor belt and a second conveyor belt, with the first conveyor belt located at the bottom and flush with the counting conveyor belt.

[0030] The paper feeding unit 1 includes a paper feeding baffle 16 for passing through a single sheet of paper 17.

[0031] In this embodiment, the paper feeding and counting unit 1 is located at the paper inlet end of the machine and includes a paper feeding channel and a paper feeding baffle 16. The paper feeding baffle 16 is vertically installed in the paper feeding channel, and the gap between it and the bottom surface of the channel is adjusted to be slightly greater than the thickness of a sheet of paper, ensuring that only a single sheet of paper 17 is allowed to pass through at a time, thus preventing counting errors caused by overlapping sheets from the source.

[0032] The paper feeding and counting unit 1 includes a paper feeding frame and a paper feeding conveyor belt. After the paper 17 passes through the paper feeding baffle 16, it is conveyed to the counting conveyor belt. A counting photoelectric sensor 15 is provided above the counting conveyor belt to count the number of paper 17 passing through.

[0033] The layer-changing mechanism is installed at the connection between the end of the counting conveyor belt and the inlet of the layered conveyor belt group, and includes a swing arm 13 and a cylinder 14. The swing arm 13 is generally L-shaped, with its shaft fixed to the frame. The piston rod end of the cylinder 14 is hinged to the short arm of the swing arm 13. The extension and retraction of the cylinder causes the swing arm 13 to swing between a horizontal and an inclined position. When the swing arm 13 is in the horizontal position, the upper surface (support surface) of its long arm is flush with the surface of the counting conveyor belt and the first conveyor belt, allowing the paper 17 to smoothly slide into the first conveyor belt horizontally. After the cylinder 14 extends, it tilts the swing arm 13 upwards, guiding the subsequent paper 17 to the inlet of the second conveyor belt, thus achieving layer changing. The tilt angle of the swing arm 13 is controlled according to the number of layers in the layered conveyor belt group to change the flow direction of the paper, achieving zoned stacking, such as... Figure 5 and Figure 6 As shown.

[0034] The swing arm 13 controls the cylinder 14 to swing via a solenoid valve, thereby changing the path of the paper 17. The swing arm 13's action time is manually set according to the set number of sheets. After the number of sheets is set, the counting photoelectric sensor 15 counts to the correct value and then controls the swing arm 13 to move. When the current sheet is continuously fed, the swing arm 13 will swing continuously according to the set number of sheets.

[0035] like Figure 7 As shown, the layered conveyor belt group is connected end-to-end with the counting conveyor belt, including a first conveyor belt (lower layer) and a second conveyor belt (upper layer) arranged in an overlapping manner. It buffers the received paper in a fish-scale pattern, as shown in the diagram. Figure 8 As shown; the first conveyor belt and the counting conveyor belt are on the same horizontal plane, and the second conveyor belt is installed directly above the first conveyor belt via a bracket. The vertical distance between the two should ensure that the paper runs independently on each layer without interfering with each other. The number of layers in the layered conveyor belt group can be set as needed.

[0036] like Figure 9 As shown, the counting stacking unit 3 includes a stacking frame, annular guide rails 5, side baffles 8, and push rods 6. The annular guide rails 5 are symmetrically arranged on the stacking frame, the push rods 6 are spaced apart on the annular guide rails 5, and the side baffles 8 are installed on both sides of the stacking frame.

[0037] The counting stacking section 3 also includes a rotating baffle 7 and a paper-blocking rod 6. The rotating baffle 7 is disposed at the outlet end of the stacking frame, and the paper-blocking rod 6 is disposed at the inlet end of the stacking frame.

[0038] The counting stacking section 3 includes multiple stacking stations, with adjacent push rods 6 on the same annular guide rail 5 forming a stacking station.

[0039] In this embodiment, the counting and stacking unit 3 is located downstream of the conveying buffer unit 2, and includes a stacking frame, two sets of symmetrically arranged annular guide rails 5, several push rods 6, a rotating baffle 7, a side baffle 8, and a paper stop bar 9. The two sets of annular guide rails 5 are respectively installed on the left and right sides of the stacking frame, and several push rods 6 span across the annular guide rails 5 at equal intervals. Adjacent push rods 6 on the same annular guide rail 5 form an independent stacking station. The push rods 6 on the two annular guide rails 5 cooperate with each other to realize the stacking of the paper 17.

[0040] The circular guide rail 5 drives the push rod 6 to circulate, causing the stacked papers 17 to be output sequentially from the outlet to the next station. Side baffles 8 are fixed to both sides of the stacking frame to laterally limit the paper stack within the station. A paper guide rod 9 is installed at the inlet end of the stacking frame to limit the sliding distance of the paper after it enters the station, ensuring the rear end of the paper stack is neat. A rotating baffle 7 is installed at the outlet end of the stacking frame and is driven to rotate by a servo motor.

[0041] Taking two workstations as an example, the first workstation 18 is located at the inlet, and the second workstation 19 is located at the outlet. Paper 17 falls into the workstations through the conveyor buffer section. The first workstation 18 is used to receive the lower layer of products from the conveyor buffer section, and the second workstation 19 is used to receive the upper layer of products from the conveyor buffer section. When the products from the first workstation 18 are pushed to the second workstation 19 by the pusher 6, they are stacked on top, ultimately achieving the number of sheets of paper per stack preset by the operator, and the paper stacks are neatly arranged and output to the next process flow. The side baffles 8 are divided into left and right sides, which are adjusted according to the width of the paper to limit the gap in the width direction; the rotating baffle 7 restricts the paper in the second workstation 19. When the pusher 6 moves, the rotating baffle 7 opens, and when the pusher 6 stops, the rotating baffle closes; the stacking of paper 17 is constrained by the side baffles 8, the paper stop bar 9, the pusher 6, and the rotating baffle 7.

[0042] like Figure 10As shown, the paper receiving output unit 4 includes a paper receiving frame, a rear tapping rod cylinder assembly 10, a rubber-coated drive roller 11, and a guide plate 12. The rear tapping rod cylinder assembly 10 and the rubber-coated drive roller 11 are overlapped and installed at the inlet end of the paper receiving frame. The guide plate 12 is installed on the paper receiving frame and is arranged opposite to the rear tapping rod cylinder assembly 10 and the rubber-coated drive roller 11.

[0043] In this embodiment, the paper receiving output section 4 is located downstream of the counting stack section 3, and receives products when the paper stack is output from the counting stack section 3. It includes a paper receiving frame, a rear-tapping cylinder assembly 10, a rubber-coated drive roller 11, and a guide plate 12. The rear-tapping cylinder assembly 10 and the rubber-coated drive roller 11 are mounted overlapping each other at the inlet end of the paper receiving frame. The rubber-coated drive roller 11 contacts the paper stack, providing a forward frictional driving force to the paper stack. The guide plate 12 is vertically mounted on the paper receiving frame, defining the stopping position of the front end of the paper stack. The tapping rod of the rear-tapping cylinder assembly 10 extends to bring the paper stack closer to the guide plate 12, tidying up the paper stack and making it neat, facilitating subsequent packaging processes.

[0044] The specific process is as follows: When the product at the second station 19 of the counting and stacking section 3 is pushed out by the pusher 6, the rubber-coated drive roller 11, driven by the motor, keeps the roller speed consistent with the pusher 6, conveying the paper stack into the space between the rear tapping cylinder assembly 10 and the guide plate 12. The guide plate 12 is adjusted by the operator according to the product size. After the paper stack falls in, the rear tapping cylinder assembly 10 extends to tap and align the paper stack. After aligning, the cylinder retracts. After the action is completed, the paper stack is automatically output by the lower support roller. The output direction can be selected according to the site and operating habits. The output section can also be installed according to the actual situation, with the output direction consistent with the running direction of the stacking section.

[0045] Example 2 A method for controlling the paper transport direction of a fully automatic high-speed counting paper receiving machine, the method comprising: S1. Determine the number of layers in the transport buffer section 2; S2. Determine the tilt angle of each layer based on the number of layers; S3, the counting stacking section 3 counts the number of papers 17 passing through and changes the tilt angle of the layer changing mechanism.

[0046] In this embodiment, the operator first inputs the paper receiving task parameters on the control panel: the number of sheets N per batch (e.g., 50 sheets) and the overall machine running speed V (e.g., 4 m / s). The control system calculates the required buffer capacity based on the stacking cycle T of a single station in the counting stacking section 3 (determined by the paper arrival frequency and station capacity), and then determines the number of layers to be used in the layered conveyor belt group. In this embodiment, when each batch N ≤ 50 sheets, a 2-layer layered conveyor belt is used; when 50 sheets < N ≤ 100 sheets, a 3-layer layered conveyor belt is used (in which case a third layered conveyor belt can be added based on Embodiment 1).

[0047] Second, the control system calculates the target tilt angle of the swing arm 13 corresponding to each layer-changing mechanism based on the layer number M determined in step S1. Taking a 2-layer layer (M=2) as an example: First layer (first conveyor belt, horizontal layer): the swing arm 13 is kept horizontal with an inclination angle of 0°, and the piston rod of the cylinder 14 is in the extended state; Second layer (second conveyor belt, upper layer): The swing arm 13 tilts upward to an angle of about 15°, the piston rod of the cylinder 14 retracts, and the paper is deflected upward along the inclined surface of the swing arm 13 and then introduced into the inlet of the second conveyor belt.

[0048] The aforementioned tilt angle value is determined by the system's preset calibration data table and is finely adjusted and compensated according to the actual paper weight and conveying speed to ensure that the flight trajectory of the paper when it is introduced into each layer accurately falls into the effective paper receiving area of ​​the corresponding conveyor belt.

[0049] Third, after the machine is running, the point-counting photoelectric sensor 15 continuously counts the paper 17 passing through the counting conveyor belt, and the control system compares the current count value with the preset layer-changing trigger threshold in real time: When the current station count value is less than N (the quantity of this batch has not been reached), the swing arm 13 maintains the current layer angle, and the paper 17 continues to be fed into the current layer conveyor belt, which then transports the paper to the corresponding stacking station. When the current station count reaches N, the control system sends a switching command to the cylinder 14. The cylinder 14 completes the action within the time interval between two adjacent sheets of paper. The swing arm 13 switches from the current tilt angle to the corresponding tilt angle of the next layer. The subsequent sheets of paper 17 are guided to the next layer of conveyor belt and enter the next stacking station to start a new batch of stacking. At the same time, the rotating baffle 7 is opened, and the stacked paper at the workstation enters the paper receiving output section 4 for output. After the output is completed, the rotating baffle 7 is closed, and the workstation continues to circulate to the paper receiving area along the circular guide rail 5, waiting for the next use. In this cycle, each conveyor belt and each stacking station alternately receives, stacks, and outputs paper, keeping the whole machine running at a continuous high speed without having to stop and wait when switching batches.

[0050] In the above control method, the response time of the layer-changing action is determined by the specifications of the cylinder 14. For example, the action time of the cylinder 14 is set by setting a specific distance when the paper is transported in the paper feeding unit 1. Therefore, the layer-changing action can be reliably completed within the gap between adjacent papers, and there will be no situation where the paper is blocked or clamped by the swing arm 13 at the moment of layer changing, thus ensuring the reliability of layer changing.

[0051] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
