Description

Technical Field

[0001] The present application relates to the field of financial equipment, and particularly to a movable paper tape pressing mechanism and a bundling machine. Background Art

[0002] In financial institutions, after a stack of banknotes is counted, a bundling paper tape is required to bundle the stacked banknotes.

[0003] Currently, many institutions use bundling machines to bundle banknote stacks. The specific operation process is as follows: First, a bundling paper tape with hot glue coated on one side is sent into a paper tape slot on the circumference of a banknote placing port through a driving mechanism and winds around at least one week. Then, a stacked banknote stack is placed into an oval hole of the banknote placing port along the length direction of the banknote, and half of the length of the banknote is placed. Then, the inner wall surface of the paper tape slot slides inward along the depth direction of the oval hole of the banknote placing port, translates and opens, and the bundling paper tape falls on the banknote stack. At this time, a pressing tongue translates from the outside to press the lower part of the paper tape head of the bundling paper tape against the banknote stack. A paper tape opening allowing the bundling paper tape to pass through is opened on the pressing tongue, and the bundling paper tape passes through the paper tape opening before entering the paper tape slot. Then, the driving mechanism rotates in the reverse direction to tighten the bundling paper tape and bundle the banknote stack tightly. Next, a hot glue cutting mechanism translates to contact and press the bundling paper tape, and then heats and melts the hot glue to firmly paste the overlapping part of the bundling paper tape. Finally, a paper cutting knife translates and cuts the bundling paper tape. The bundling operation of the banknote stack is completed.

[0004] However, in the existing bundling machines, the paper tape slot is integrally opened on the bundling body. If an accident such as paper tape jamming occurs, the entire bundling machine needs to be disassembled for repair, which is very inconvenient. And at the position where the bundling paper tape just enters the paper tape slot around the banknote placing port, that is, at the entrance of the paper tape slot, it is often a frequent area where paper jams occur.

[0005] Therefore, the existing bundling machine technology still needs to be improved and developed. Summary of the Invention

[0006] Aiming at the technical defect that it is inconvenient to repair when a paper jam or other faults occur in the existing bundling machine, the purpose of the present application is to provide a movable paper tape pressing mechanism, a bundling machine equipped with the paper tape pressing mechanism, and a usage method, which can smoothly bundle banknote stacks when the bundling machine is working, and when a paper jam accident occurs in the bundling machine, it can be easily opened to facilitate disassembly and repair.

[0007] The technical solution of the present application is as follows:

[0008] The first aspect of the present application is to provide a movable paper pressing belt mechanism, which includes a main body and a cylindrical paper pressing belt wheel column. A rotating hole for installing a rotating shaft is provided at the end of the main body, and a paper pressing belt wheel column slot with an open top is provided at the top of the main body. The paper pressing belt wheel column is placed in the paper pressing belt wheel column slot, and the paper pressing belt wheel column slot allows the paper pressing belt wheel column to move towards the opening direction, and there is a gap between the paper pressing belt wheel column and the main body.

[0009] In a preferred embodiment, the main body is provided with a cavity, and an elastic member is provided in the cavity. One end of the elastic member abuts against the paper pressing belt wheel column and gives a force to the paper pressing belt wheel column towards the opening direction.

[0010] In a preferred embodiment, the main body is further provided with a hook shaft, and the paper pressing belt wheel column slot is located between the hook shaft and the rotating hole.

[0011] In a preferred embodiment, a plastic sleeve for increasing friction during paper feeding is sleeved on the column surface of the paper pressing belt wheel column.

[0012] More preferably, the elastic member is a paper pressing torsion spring. One end of the paper pressing torsion spring is fixed on the wall body, and the other end contacts and outwardly presses against the hole edge of the bottom of the fixed shaft to the rotating hole away from the cavity, so as to force the paper pressing belt wheel column to maintain a tendency to leave the cavity outward through elasticity.

[0013] The second aspect of the present application is to provide a bundling machine equipped with the above-mentioned paper pressing belt mechanism. The bundling machine includes a banknote placing port for placing a stack of banknotes, a slidable inner wall ring closely attached to the inner wall surface of the banknote placing port, a paper tape slot for placing a bundling paper tape provided between the inner wall ring and the inner wall surface, and a paper feeding channel for feeding paper to the paper tape slot. The paper pressing belt mechanism presses the gap between the paper pressing belt wheel column and the main body on the paper feeding channel, or the outer end of the paper pressing belt wheel column faces the paper feeding channel.

[0014] In a preferred embodiment, on the paper feeding channel, the bundling machine is provided with a missing part, and the paper pressing belt mechanism is located in the missing part; a rotating shaft is provided at one end of the missing part, and the rotating shaft is inserted into the rotating hole.

[0015] In a preferred embodiment, the missing part is provided with a hook, and the hook hooks the hook shaft to hold the paper pressing belt mechanism in the missing part.

[0016] In a preferred embodiment, the bundling machine further includes a driving rotating wheel for driving the bundling paper tape provided at the entrance of the paper tape slot. The paper pressing belt mechanism is rotatably fixed on the bundling machine through the rotation center, and the paper pressing belt wheel column is arranged facing the driving rotating wheel.

[0017] In a preferred embodiment, a translationally movable pressing tongue is provided on the outer side of the paper tape groove and is located above the driving wheel. The pressing tongue is provided with a paper tape opening for allowing the strapping paper tape to pass through.

[0018] More preferably, in general, at least one side of the strapping paper tape is coated with hot glue. To this end, a hot glue cutting mechanism is further provided on the outside of the paper tape groove above the pressing tongue, including a heating block for heating and gluing the strapping paper tape, and a paper cutter provided on the lower side of the heating block.

[0019] The present application also discloses a method for resolving paper jams in the binding machine, which comprises at least the following steps:

[0020] A. Open the hook and apply external force to the paper pressing mechanism, or under the action of gravity, the paper pressing mechanism rotates around the shaft, exposing the paper pressing roller column;

[0021] B. Move the platen roller toward the platen roller slot opening and remove the jammed paper.

[0022] The present application discloses a movable paper pressing belt mechanism and a binding machine, as well as a method for solving paper jams. By setting a rotation center at one end of the paper pressing belt mechanism and a hook shaft at the other end, after being installed on the binding machine, the mechanism can be manually opened and closed around the rotation center. When closed, the hook on the binding machine hooks the hook shaft, fixing the paper pressing belt mechanism so that the paper pressing belt wheel column rotates in conjunction with the active wheel, driving the binding paper tape into the paper tape slot. When a paper jam or other fault occurs, the paper pressing belt mechanism is manually rotated to open and clear the obstacle. The movable paper pressing belt mechanism and binding machine disclosed in the present application greatly facilitate the operation of troubleshooting paper jams in the binding machine without affecting the normal operation of the binding machine, saving maintenance time and thus improving production efficiency.

[0027] This application provides a movable paper pressing belt mechanism and a binding machine. To make the purpose, technical solution, and effects of this application more clear and explicit, the application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0028] In a preferred embodiment of the present application, the specific structure of the movable paper pressing belt mechanism 1 disclosed in the present application is as follows: Figure 1 As shown, it includes a main body 11 and a concave groove cavity provided in the main body 11 , and the concave groove cavity occupies most of the volume of the main body 11 .

[0029] At the top of the body 11, at the opening of the concave groove cavity, the opposite side walls of the concave groove cavity are provided with a paper pressing wheel column slot protruding from the body 11 and open at the upper end. The cylindrical paper pressing wheel column 12 is placed in the paper pressing wheel column slot, and a gap is left between the paper pressing wheel column of the paper pressing belt mechanism and the body. The paper pressing wheel column 12 is matched with the two paper pressing wheel column slots through a fixed shaft 121 set at the axis. The paper pressing wheel column slot can be set to a certain length, or the opening can be larger than the diameter of the paper pressing wheel column. In this way, not only can the fixed shaft 121 rotate freely in the rotating hole, but it can also make a certain range of translation in the direction of the opening, and even detach from the paper pressing wheel column slot.

[0030] In a more preferred embodiment of the present application, a plastic sleeve 122 is further provided on the cylindrical surface of the paper pressing wheel column 12 for increasing frictional paper feeding.

[0031] In a more preferred embodiment of the present application, a paper pressing torsion spring 13 is further provided on the main body 11, preferably in the concave groove cavity, one end of the paper pressing torsion spring 13 is fixed on the main body 11, and the other end contacts and supports the fixed shaft 121, and is used to force the fixed shaft 121 and the paper pressing wheel column 12 to move away from the direction of the opening of the paper pressing wheel column slot through the elasticity of the torsion spring.

[0032] One end of the paper pressing belt mechanism 1 is also provided with a rotation center 14, including a hole for installing a rotating shaft. Correspondingly, a hook shaft 15 is provided at the other end relative to the rotation center 1. Thus, when the paper pressing belt mechanism 1 is rotatably defined to the bundling machine through the rotation center 14, the paper pressing belt mechanism 1 can be manually rotated by an operator to open and close. When the paper pressing belt mechanism 1 is closed, a hook 8 around the driving runner 4 on the bundling machine, as shown in Figure 2 the opening maintenance drawing, is operated by the operator to hook the hook shaft 15, thereby fixing the paper pressing belt mechanism 1.

[0033] This application also discloses a bundling machine equipped with a movable paper pressing belt mechanism 1. In a specific embodiment of the bundling machine, the specific structure of the bundling machine is as shown in Figure 3 shown. The bundling machine includes a banknote placing opening 2, and the banknote placing opening 2 is used for placing a stack of sorted and neatly stacked banknotes. The banknotes are placed into the banknote placing opening 2 along the length direction, but only half of the length of the banknotes is placed, so that bundling occurs at the middle part of the banknotes.

[0034] On the inner wall surface of the banknote placing opening 2, close to the wall surface but at a certain distance away, a circle of slidable inner wall rings (not marked in the figure) is provided. At the opening of the banknote placing opening 2, a paper tape slot for passing the bundling paper tape 3 is formed between the inner wall ring and the inner wall surface. The paper tape slot only needs to have a width greater than the thickness of the bundling paper tape 3 and allow the bundling paper tape 3 to pass freely. At the entrance of the paper tape slot, a driving runner 4 for driving the bundling paper tape 3 is provided. The bundling machine also has a paper supply channel, and the paper pressing belt mechanism 1 is located on the paper supply channel. The paper pressing belt mechanism presses the bundling paper tape through the gap between the wheel column and the main body 11 on the paper supply channel, or on the other side of the wheel column of the paper pressing belt mechanism. When the paper pressing belt mechanism 1 is installed on the bundling machine and closed, the paper pressing belt wheel column 12 is arranged opposite to the driving runner 4.

[0035] Generally, the paper pressing belt mechanism is installed at the position where paper jams most easily. For example Figure 2 and Figure 3 , on the paper supply channel, the bundling machine is provided with a missing part, and the paper pressing belt mechanism 1 is located in the missing part; one end of the missing part is provided with a rotation center shaft 9, and the rotation center shaft 9 is inserted into the hole. The missing part is provided with a hook 8, and the hook 8 hooks the hook shaft 15 to hold the paper pressing belt mechanism in the missing part. It can ensure that when closed, the paper pressing belt wheel column 12 and the driving runner 4 fully clamp the bundling paper tape 3 with a certain pressure.

[0036] Specifically, during assembly, the paper pressing belt mechanism 1 is rotatably connected to the rotation center shaft 9 on the binding machine through the rotation center 14 and is confined to the binding machine. When the operator manually rotates the rotation center 14 around the rotation center shaft 9 to close the paper pressing belt mechanism 1, the paper pressing belt wheel column 12, such as Figure 1 As shown, there is at least one linear contact between the driving roller 4 and the paper pressing roller column 12. In a more preferred embodiment, the outer surface of the roller column of the paper pressing roller 12 is covered with a plastic sleeve 122 with a certain degree of elasticity. Therefore, when the paper strap 3 is sandwiched between the driving roller 4 and the paper pressing roller column 12, the paper strap 3 can be driven to move completely in accordance with the rotation of the driving roller 4 without slipping. In other words, the contact pressure with the driving roller 4 is increased, thereby further ensuring the effective driving of the paper strap 3.

[0037] In a more preferred embodiment of the binding machine of the present application, a translatable pressing tongue 5 is provided on a portion of the working path after the strapping paper 3 leaves the driving wheel 4, outside the strapping groove, in a direction away from the driving wheel 4. In another more preferred embodiment, at least one side of the strapping paper 3 is coated with hot glue, and the strapping machine is further provided with a translatable hot-melt cutting mechanism, with the pressing tongue 5 and the hot-melt cutting mechanism being sequentially arranged above the driving wheel 4. More specifically, the hot-melt cutting mechanism includes a paper cutting knife 6 disposed adjacent to the pressing tongue 5 and a heating block 7 disposed further away. The purpose of providing the pressing tongue 5 is to allow the pressing tongue 5 to translate against the lower portion of the strapping paper 3 after the strapping paper 3's head travels along the strapping groove, returns, and overlaps the strapping paper 3, thereby preventing the strapping paper 3 from sliding when tightening the strapping paper 3.

[0038] Because the pressing tongue 5 is used to press the inner side of the strapping paper tape 3 by translation, and returns to the lower part of the overlapping paper tape head after circling the paper tape groove once, it needs to pass through the movement path of the strapping paper tape 3 before contacting the lower part of the paper tape head. Therefore, a paper tape opening is opened on the pressing tongue 5 to allow the strapping paper tape 3 to pass through. The strapping paper tape 3 first passes through the paper tape opening before entering the paper tape groove.

[0039] The heating block 7 is used to heat and bond the overlapping portions of the paper strapping 3 after translating to contact the paper strapping 3. Obviously, the paper strap head needs to at least partially reach the position of the heating block 7, and preferably exceed the distal end of the heating block 7 to ensure sufficient contact for thermal bonding.

[0040] A paper cutter 6 is provided between the heating block 7 and the pressing tongue 5. After the heating block 7 completes heating and bonding the strapping paper tape 3, the strapping paper tape 3 is cut by translation, thereby completing the entire strapping operation.

[0041] In summary, the working process of the binding machine with a movable paper pressing belt mechanism disclosed in this application is as follows:

[0042] First, the operator manually rotates and opens the paper pressing belt mechanism 1, thereby inserting the bundling paper belt 3 into the opening of the paper belt slot, and inserting the stack of folded banknotes into the banknote insertion port 2. The banknote stack is inserted along the length direction of the banknotes, but only half of the length is inserted, so that the bundling paper belt 3 is bundled in the middle of the banknote stack.

[0043] The tape head is then pulled through the drive roller 4 and the tape pressure mechanism 1, passing through the tape opening and then into the tape slot in an upward direction. The operator manually rotates the tape pressure mechanism 1 to close it, and manually hooks the hook 8 onto the hook shaft 15 to completely close the tape pressure mechanism 1. This forces the tape pressure roller post 12 to press against the surface of the drive roller 4, sandwiching the strapping tape 3 with a certain amount of pressure, facilitating translational movement through rotation.

[0044] At this time, the driving wheel 4 starts to rotate and drive the strapping paper tape 3 to circle along the paper tape groove for at least one circle, so that after the strapping paper tape 3 is partially overlapped, the position of the paper tape head preferably exceeds the upper edge position of the heating block 7, and the driving wheel 4 stops rotating.

[0045] Then, the inner wall ring slides along the depth direction of the banknote insertion slot 2, toward the inside of the banknote insertion slot 2, exposing the paper strap 3. The paper strap 3 falls onto the banknote stack. At this time, the pressing tongue 5 translates to press the lower portion of the paper strap head toward the banknote stack, and the active wheel reverses, tightening the paper strap 3. Next, the hot-bonding and cutting mechanism translates to contact and press the paper strap 3. After the heating block 7 heats and bonds the paper strap 3, the paper cutter 6 translates to cut the paper strap 3, thus completing the entire banknote stacking operation.

[0046] When a paper jam occurs in the binding machine, the operator can take the following steps:

[0047] First, stop the rotation of the active rotating wheel 4, and then manually rotate to open the paper pressing belt mechanism 1 to expose the entire entrance path of the binding paper tape 3, so as to facilitate clearing any paper jams. Specifically, open the hook 8, pull the hook shaft 15, or under the action of gravity, the paper pressing belt mechanism 1 rotates around the rotation center shaft 9 to expose the paper pressing belt wheel column 12. The elastic force of the paper pressing torsion spring 13 pushes the paper pressing belt wheel column 12 towards the opening direction of the paper pressing belt wheel column slot, thereby increasing the gap between the body 11 and the paper pressing belt wheel column 12, and taking out the paper jam.

[0048] A bundle tying machine with a movable paper pressing belt mechanism and a usage method disclosed in the present application, by setting a movable and openable and closable paper pressing belt mechanism 1 at the entrance position of the paper tape slot around the banknote placing port 2 of the bundle tying machine. After the bundle tying machine works and the binding paper tape 3 passes through the active rotating wheel 4, manually close the paper pressing belt mechanism 1, so that the paper pressing belt wheel column 12 cooperates with the active rotating wheel 4 to rotate and send the binding paper tape 3 into the paper tape slot; and when a paper jam or other faults occur, manually open the paper pressing belt mechanism 1 to remove the obstacles. Without affecting the work of the bundle tying machine, it greatly facilitates the operation of troubleshooting paper jams of the bundle tying machine, saves maintenance time, and thus improves production efficiency.
