Description

Technical Field

[0001] This invention relates to the field of paper counting machine technology, and more particularly to a multi-station paper counting machine for counting irregularly shaped papers. Background Technology

[0002] Currently, paper counting machines are all single-station types. After counting one stack of paper, the machine pauses, and then the second stack of paper is put in to continue counting. This wastes a lot of time between taking out and putting in the next stack of paper, affecting the efficiency of paper counting. This is especially true when large exams are being held and the number of papers is being checked. Therefore, many exam sites use multiple paper counting machines to divide the work. However, a single paper counting machine costs at least tens of thousands and sometimes hundreds of thousands of yuan. So, how can we improve paper counting efficiency? On the one hand, we need to increase the paper counting speed, and on the other hand, we need to reduce the time wasted in taking out and putting in paper during the counting process.

[0003] In addition, irregularly shaped paper is paper that differs from ordinary rectangular paper. For example, the paper from most packaging boxes and bags is irregularly shaped paper, also called irregular paper. In order to ensure the stability of later assembly, many folds are added. Currently, the counting of this type of irregular paper can only be marked by the quantity printed on the printing press at the factory as a whole package or box. However, when it is circulated in the market, the exact number can only be determined by manual calculation. In addition, in the early years when material prices were low, most manufacturers directly gave away this type of irregularly shaped paper with the products, and the quantity was always more than the quantity. However, with the rise in prices, many manufacturers have now started to charge for it and will send out packaging paper with an accurate quantity to match the products. Therefore, irregularly shaped paper counting machines have become in demand. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a multi-station and countable irregular paper counting machine to solve the technical problems mentioned in the background art.

[0005] To solve the technical problem, the present invention adopts the following technical solution:

[0006] A multi-station paper counting machine for counting irregularly shaped papers includes a paper counting body supported by a machine frame. The paper counting body is equipped with a paper counting mechanism and an operating mechanism. The paper counting mechanism includes a paper counting head and a pressure plate. An open paper counting area is recessed on one side of the paper counting body. The paper counting end of the paper counting head is located on one side of the open paper counting area. The operating mechanism includes a turntable and several paper counting stations mounted on the turntable. The paper counting stations can rotate with the turntable to the position of the open paper counting area corresponding to the paper counting end of the paper counting head. The turntable is driven to rotate by a drive device at its bottom. The paper counting head is equipped with paper counting claws and a lever. The paper counting claws are equipped with suction holes for paper suction.

[0007] Specifically, the machine frame includes a rear support frame, a top support frame, and a bottom support frame, wherein the rear support frame, the top support frame, and the bottom support frame together enclose an open paper counting area, and the paper counting head is located at the upper end of the bottom support frame.

[0008] Specifically, the paper counting station is a regular paper counting station or a non-standard paper counting station. Several paper counting stations are arranged in a circular array along the turntable. Each paper counting station includes a first baffle, a second baffle, and a paper feeding sensor. The first baffle and the second baffle are set at right angles and form a paper counting slot in the middle. The right-angled end of the paper to be tested can extend into the paper counting slot to enter the open paper counting area for counting.

[0009] Specifically, the paper counting station includes a regular paper station and a non-standard paper station. The regular paper station includes a first baffle, a second baffle, and a paper feeding sensor. The first baffle and the second baffle are set at right angles and form a paper counting slot in the middle. The right-angled end of the paper to be tested can extend into the paper counting slot and enter the open paper counting area for counting. The non-standard paper station is located in the empty area between the two regular paper stations.

[0010] Specifically, the turntable has an arc-shaped fixing area, and two adjacent arc-shaped fixing areas are mirror-symmetrical. Several fixing holes are distributed along the arc line of the arc-shaped fixing area. Both the first baffle and the second baffle have through holes. Screws pass through the through holes to fix the first baffle and the second baffle in the arc-shaped fixing area. By fixing it at different positions on the arc-shaped fixing area, the width of the paper counting slot between the first baffle and the second baffle can be adjusted, thereby adjusting the space for counting paper of different widths and shapes. The paper counting claw is linear or non-linear and includes at least two paper suction areas, each of which has a suction hole. Each suction hole can correspond to the folding angle of different shaped papers.

[0011] Specifically, the drive device includes a motor, a drive gear, and a driven gear. The motor is fixedly mounted on the machine frame, and its output end is fixedly connected to the drive gear. The drive gear meshes with the driven gear, and the driven gear is fixedly mounted on the bottom of the turntable. A shaft groove is formed on the inner side of the driven gear, and a conductive slip ring is fixedly mounted on the inner side of the shaft groove. The other end of the conductive slip ring is fixedly connected to the machine frame. By installing the conductive slip ring, the signal line can be prevented from tangling when the turntable rotates. The device also includes a positioning sensing device, which includes a frame positioner and a turntable positioner. The turntable positioner consists of several sensors corresponding to the opposite sides of different workstations.

[0012] Specifically, it also includes a support baffle. The turntable has a magnetic metal surface, and the support baffle has a recessed support position that can hold the paper to be tested. The lower end of the support baffle has a magnetic attraction surface that magnetically attracts the magnetic metal surface of the turntable, allowing the support position of the support baffle on the turntable to be freely adjusted.

[0013] Specifically, a number of support guide rods are provided on one side of the machine frame, and an upper support plate and a lower support plate are slidably arranged on the support guide rods. One end of the pressure plate is fixedly connected to the upper support plate, and one end of the paper counting head is fixedly connected to the lower support plate.

[0014] Specifically, the lower support plate is provided with a clamping seat, which includes an upper clamping seat and a lower clamping seat. The upper clamping seat is fixedly connected to the lower support plate, and the upper clamping seat is fixedly connected to the lower clamping seat. A clamping groove is formed between the upper clamping seat and the lower clamping seat. The machine head shaft passes through and is clamped in the clamping groove. The support guide rod includes several main guide rods arranged close together and a secondary guide rod arranged away from the main guide rod. The clamping seat is arranged on the upper end surface of the lower support plate between the main guide rod and the secondary guide rod. The upper support plate and the lower support plate are provided with sliding holes corresponding to the positions of the main guide rod and the secondary guide rod. Linear bearings are arranged in the sliding holes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] (1) This invention patent abandons the original closed paper counting form and instead designs an open paper counting area. Different paper counting stations that rotate through the turntable will not be obstructed in any way. In this way, multiple paper counting stations can realize cyclic paper counting. That is, when the first paper counting station rotates to the open paper counting area to count paper, the second paper counting station puts the paper to be counted at the same time. After the first paper counting station finishes counting the paper, the second paper counting station can immediately rotate to the open paper counting area to count paper. This can greatly reduce the time for taking out and putting in paper and improve paper counting efficiency.

[0017] (2) Unlike the traditional closed paper counting area, this invention sets up an open paper counting area, which can realize the paper counting station for irregularly shaped paper or the paper counting station for ordinary paper as the turntable rotates to the paper counting area for paper counting. It can also switch freely between the paper counting station for ordinary paper and the paper counting station for irregularly shaped paper. At the same time, for the paper counting station for irregularly shaped paper, in this invention, its width can be controlled by two baffles, or the gap area between two ordinary paper counting stations can be used directly as the paper counting station for irregularly shaped paper. The two can be flexibly changed to adapt to the paper counting and placement of irregularly shaped paper of different widths and shapes. At the same time, the paper counting claw is set into multiple paper suction areas, and a suction hole is set on each paper suction area to suction paper for different fold angles of irregularly shaped paper. Meanwhile, the turntable is set with mirrored arc-shaped mounting holes for adjusting the fixed position of the baffles to adjust the width of the gap between the two baffles.

Detailed Implementation

[0032] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] refer to Figures 1 to 13 :

[0034] refer to Figure 1-8 This invention discloses a multi-station counting machine for counting irregularly shaped papers, comprising a counting machine body 100 supported by a machine frame. The counting machine body is equipped with a counting mechanism and an operating mechanism. The counting mechanism includes a counting head 1 and a pressure plate 2. An open counting area 3 is recessed on one side of the counting machine body 100, and the counting end of the counting head 1 is located on one side of the open counting area 3. The operating mechanism includes a turntable 4 and several counting stations 5 mounted on the turntable 4. Each counting station 5 can rotate with the turntable 4 to the position corresponding to the counting end of the counting head 1 in the open counting area 3. The turntable 4 is driven to rotate by a driving device 6 at its bottom. The counting head 1 is equipped with counting claws 11 and levers 12 (see reference). Figure 7 The counting claw 11 has a suction hole 111 for suctioning paper. One end of the counting claw 11 is connected to the compressor through an air pipe. The compressor provides suction to the counting claw 11. The counting claw 11 and the lever 12 are both connected to the rocker arm assembly of the counting machine head (existing technology). The counting claw 11 is used to suck up the paper to form a gap, and the lever 12 is used to open the gap. After the previous paper is sucked up by the counting claw 11 and a small gap is created, the lever 12 is inserted to widen the gap. Then the counting claw 11 releases the previous paper, shakes the rocker arm assembly, and then inserts into the widened gap to suck up the next paper. The lever 12 is driven by the rocker arm assembly to repeatedly insert into the gap. At the same time, the system completes one cycle with the counting claw 11 and the lever 12, which counts as one paper. This cycle is repeated to complete the counting of paper (existing technology).

[0035] refer to Figure 1 , Figure 4 and Figure 5 Specifically, unlike traditional paper counting machines which are sealed around the perimeter, this paper counting machine features a support frame at the front end. Two paper counting baffles are placed in the middle of this frame to serve as paper counting slots. Consequently, the operating panel (for placing paper) can only be a snap-fit ​​type, making it impossible to set up multiple paper counting areas. Furthermore, this type of traditional paper counting machine can only count irregularly shaped paper by removing the front support frame. However, after removing the front support frame, the paper counting head 1 and the pressure plate 2 lose their support. Unauthorized removal of the front support frame also affects functions such as the machine head's anti-theft alarm, thus preventing normal operation. This process often results in the manufacturer having to repeatedly send samples back and forth to the user for modification and re-adjustment, which is very troublesome. In this invention patent, in order to form an open paper counting area 3, the machine frame includes a rear support frame 101, a top support frame 102, and a bottom support frame 103. The rear support frame 101, top support frame 102, and bottom support frame 103 together enclose the open paper counting area 3. The paper counting head 1 is located at the upper end of the bottom support frame 103. Machine components such as compressors, head lifting motors 61, pressure plate lifting motors 61, circuit boards, etc. are installed inside the bottom support frame 103. The rear support frame 101 is used to support the upper top operation box and other components.

[0036] refer to Figure 5In the absence of a front support frame, this invention provides several support guide rods 8 on one side of the machine frame. An upper support plate 10 and a lower support plate 20 are slidably mounted on the support guide rods 8. One end of the pressure plate 2 is fixedly connected to the upper support plate 10, and one end of the paper counting head 1 is fixedly connected to the lower support plate 20. Specifically, the lower support plate 20 is provided with a clamping seat 9, which includes an upper clamping seat 91 and a lower clamping seat 92. The upper clamping seat 91 is fixedly connected to the lower support plate 20, and the upper clamping seat 91 is fixedly connected to the lower clamping seat. A clamping groove 93 is formed between the upper clamping seat 91 and the lower clamping seat. The head shaft 13 passes through and is clamped in the clamping groove 93. During installation, multiple bearings can be installed in the clamping groove 93 to rotate with the head shaft 13, allowing the head to deflect to accommodate papers of different thicknesses. Unlike traditional paper counting machines where the machine head is fixed on both sides, the paper counting machine head 1 in this invention is fixed directly on one side. The support guide rod 8 that fixes the paper counting machine head does not affect the rotation of the pressure plate 2 and the turntable 4, thus enabling the formation of an open paper counting area 3 in this paper counting machine. Moreover, the paper counting machine head 1 can be used stably. Specifically, the support guide rod 8 includes several main guide rods 81 arranged close together and a secondary guide rod 82 arranged away from the main guide rods 81. The clamp 9 is arranged on the upper end surface of the lower support plate 20 between the main guide rods 81 and the secondary guide rod 82. The upper support plate 10 and the lower support plate 20 are provided with sliding holes 201 at the positions corresponding to the main guide rods 81 and the secondary guide rods 82. Linear bearings 202 are arranged in the sliding holes 201, which facilitate the up and down sliding of the upper support plate 10 and the lower support plate 20.

[0037] It is important to understand that the upper support plate 10 and the lower support plate 20 can slide up and down by a chain and motor 61 (illustration omitted here), or by a screw rotating to drive their lifting and lowering. Generally, the sliding of the upper support plate 10 drives the pressure plate 2 to descend to press the paper and to lift and release it. The lifting and lowering of the lower support plate 20 drives the counting head 1. Because the paper has a certain thickness, when the counting head 1 counts paper from bottom to top or from top to bottom, it will deflect when it reaches a certain thickness. The deflection of the counting head 1 will cause the lever and the counting claw to stop counting. At this time, the system will identify the deflection angle through the angle deflection sensor, and then raise or lower the lower support plate 20 to restore the counting head 1 to a balanced state.

[0038] As embodiments of the paper counting station 5, the present invention provides various embodiments of the paper counting station 5 to meet different paper counting needs:

[0039] refer to Figure 3 , Figure 5 and Figure 6Example 1: The paper counting station 5 is a regular paper counting station. Several paper counting stations 5 are arranged in a circular array along the turntable 4. Each paper counting station 5 includes a first baffle 51, a second baffle 52, and a paper feeding sensor 53. The first baffle 51 and the second baffle 52 are set at right angles and form a paper counting slot 54 in the middle. The right-angled end of the paper to be tested can extend into the paper counting slot 54 to enter the open paper counting area 3 for counting. The paper feeding sensor 53 can be a near-field infrared sensor. When the paper is pushed forward from the turntable 4, the sensor senses the paper and transmits the information to the main board. Then, the pressure plate 2 presses down to prepare for paper counting. The ordinary paper here refers to the commonly seen rectangular or regular paper such as A3 or A4, which can be counted using a traditional paper counting machine. However, unlike traditional paper counting machines, the turntable 4 of this invention is equipped with multiple paper counting stations 5. After the paper in the previous paper counting station 5 is started to be counted, the operator can start putting paper into the next paper counting station 5. When the paper in the first paper counting station 5 is finished counting, the operator immediately presses the rotation button, or presses a button, and the system automatically rotates the second paper counting station 5 into the paper counting area. This cycle repeats, saving the time required to take out paper, put in new paper, and press the operation button again in a traditional paper counting machine, thus improving the paper counting efficiency.

[0040] refer to Figure 13 Example 2: Unlike Example 1, in this example, the paper counting station 5 is a paper counting station for irregularly shaped paper. Several paper counting stations 5 are arranged in a circular array along the turntable 4. Each paper counting station 5 includes a first baffle 51, a second baffle 52, and a paper feeding sensor 53. The first baffle 51 and the second baffle 52 are set at right angles and form a paper counting groove 54 in the middle. The right-angled end of the paper to be tested can extend into the paper counting groove 54 to enter the open paper counting area 3 for counting. Specifically, because the irregularly shaped paper has a unique size and shape, the width between the folds to be absorbed in the irregularly shaped paper also varies greatly. Here, the turntable 4 is provided with an arc-shaped fixing area 55. Two adjacent arc-shaped fixing areas 55 are mirror-symmetrical. Several fixing devices are distributed along the arc line of the arc-shaped fixing area 55. The fixed hole 551, the first baffle 51 and the second baffle 52 are both provided with through holes. Screws pass through the through holes to fix the first baffle 51 and the second baffle 52 in the arc-shaped fixing area 55. By fixing them at different positions on the arc-shaped fixing area 55, the width of the paper counting groove 54 between the first baffle 51 and the second baffle 52 can be adjusted, thereby adjusting the space for counting paper for irregularly shaped papers of different widths and shapes. As another improvement for counting irregularly shaped papers, the paper counting claw 11 is linear or non-linear and includes at least two paper suction areas 112, each of which has a suction hole 111. Each suction hole 111 can correspond to the folding angle of different irregularly shaped papers. Here, in use, different paper counting claws 11 can be selected for installation and use according to the different shapes of irregularly shaped papers and the width between the folding angles.

[0041] refer to Figure 8 , Figure 9 and Figure 10 Example 3: Unlike the previous two examples, the paper counting station 5 in this example includes a regular paper station and a non-standard paper station, i.e., the two types of paper counting stations 5 are mixed. The regular paper station includes a first baffle 51, a second baffle 52, and a paper feeding sensor 53. The first baffle 51 and the second baffle 52 are set at right angles and form a paper counting slot 54 in the middle. The right-angled end of the paper to be tested can extend into the paper counting slot 54 and enter the open paper counting area 3 for counting. The non-standard paper station is located in the empty area between the two regular paper stations. In this way, non-standard paper and regular paper can be installed on a turntable 4. In daily use, they can be flexibly switched without having to change the turntable 4 or the type of paper counting station 5. When there is no baffle limit, the pressure of the pressure plate 2 can be adjusted by the control plate to prevent the paper to be counted from shifting.

[0042] refer to Figure 8 , Figure 9 and Figure 11 Specifically, when some of the test papers are smooth, and only the front pressure plate 2, the first baffle 51 and the second baffle 52 limit the movement, when counting the papers, because the paper is too thick, some papers may wobble at the unrestricted end. Here is a solution, specifically, it also includes a support baffle 7. The turntable 4 has a magnetic metal surface, and the support baffle 7 has a recessed support position 71 that can hold the test paper. The lower end of the support baffle 7 has a magnetic surface that magnetically attracts the magnetic metal surface of the turntable 4, and the support position of the support baffle 7 on the turntable 4 can be freely adjusted.

[0043] refer to Figure 6Specifically, in this invention, the driving device 6 includes a motor 61, a driving gear 62, and a driven gear 63. The motor 61 is a servo motor 61, which is fixedly mounted on the bottom support frame 103 of the paper counting machine body 100. The output end of the motor 61 is fixedly connected to the driving gear 62, and the driving gear 62 and the driven gear 63 mesh and move together. As a detail of the motor 61 assembly, in this invention, the diameter of the driven gear 63 is preferably larger than the diameter of the driving gear 62. A reduction motor 61 can also be installed at the end of the motor 61 to prevent the upper turntable 4 from rotating too fast and causing the paper to tail. The driven gear 63 is fixedly mounted on the bottom of the turntable 4, and a shaft groove 631 is formed on the inner side of the driven gear 63. A conductive slip ring 64 is fixedly mounted on the inner side of the shaft groove 631, and the other end of the conductive slip ring 64 is fixedly connected to the machine frame. Next, by installing a conductive slip ring 64, the signal line can be prevented from getting tangled when the turntable 4 rotates. It also includes a positioning sensing device, which includes a frame positioner 41 and a turntable positioner 42. The turntable positioner 42 is composed of several sensors corresponding to the opposite sides of different workstations. Specifically, since the frame positioner 41 is fixed in one position, while the turntable positioner 42 corresponds to each different paper counting workstation 5, and when the paper counting workstation 5 reaches the value area, the turntable positioner 42 opposite to its turntable 4 is exactly in position with the frame positioner 41. In this preferred setting, with the bottom surface of the turntable 4 as the reference, each paper counting workstation 5 has a turntable positioner 42 installed on the opposite side of the bottom surface of the turntable 4. Each turntable positioner 42 is numbered on the main control board. When the control board displays the number of the specific paper counting workstation 5 on the display screen, it is selected.

[0044] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
