Description

Technical Field

[0001] The invention relates to the field of banknote printing, and in particular to a device for punching and destroying small waste banknotes. Background Art

[0002] In the banknote printing industry, some defective products are inevitably produced during the production or printing of banknotes. Due to special digital management requirements, a certain number of small waste banknotes generated during the production process need to be collected, and then the neatly stacked bundles of small waste banknotes need to be punched for scrapping.

[0003] At present, the punching and invalidation of small waste banknotes usually involves stacking 100 waste banknotes neatly, bundling them, and then putting them into a punching machine in the form of single bundles. The punching device is used manually to punch downwards until a hole appears on each bundle of waste banknotes, and the invalidation procedure for the bundle of waste banknotes is completed.

[0004] However, the manual punching method is labor-intensive and has low punching efficiency. In addition, the waste generated by punching is directly scattered on the ground without any collection device, resulting in a dirty working environment. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a device for punching and destroying small pieces of waste banknotes, aiming to solve the problem that the current manual punching method has high labor intensity and low punching efficiency, and the waste chips generated by punching are directly scattered on the ground without a collection device, resulting in a dirty working environment.

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Please combine Figure 1-Figure 10 , which is a schematic structural diagram of a small waste banknote punching and destruction device provided in one embodiment of the present invention, the small waste banknote punching and destruction device comprises a transport component 100, a push component 200 arranged at the starting end of the transport component 100, and a punching component 300 arranged on the transport component 100, wherein:

[0032] In order to realize the function of transporting bundled waste banknotes, the transport assembly 100 includes a feeding line 110, a discharging line 120, and a transfer mechanism 130 disposed between the feeding line 110 and the discharging line 120. The feeding line 110 is disposed between the transfer mechanism 130 and the pushing assembly 200, so as to transport the bundled waste banknotes pushed out from the pushing assembly 200 to the punching assembly 300 for punching and scrapping, and then transport the scrapped bundled waste banknotes to the transfer mechanism 130, which is used to transport the scrapped bundled waste banknotes to the discharging line 120, and then collect the scrapped bundled waste banknotes.

[0033] For safety reasons, the discharging line 120 and the feeding line 110 are both installed in the cabinet 400. The feeding line 110 includes a first transmission motor 111 and at least three first-class transmission rollers 112 arranged in the cabinet 400. In this embodiment, four first-class transmission rollers 112 are used, and the output end of the first transmission motor 111 is connected to one of the first-class transmission rollers 112 through a first transmission belt 113. Four first-class transmission rollers 112 are distributed in the cabinet 400 in an isosceles trapezoidal shape, and transmission gears 115 are provided on both ends of each first-class transmission roller 112. The transmission gears 115 at the same end of the four identical first-class transmission rollers 112 are connected through the same second transmission belt 114, and the second transmission belt 114 is connected by meshing with the transmission gear 115 at the same end. At the same time, the transmission gears 115 arranged on the same side of the top are also connected through a transmission toothed belt 116, so that the first transmission motor 111 drives one of the first-class transmission rollers 112 to rotate, thereby driving the transmission toothed belt 116 to rotate.

[0034] Furthermore, in order to transport bundled waste banknotes, a transport plate 117 is provided between the two transmission toothed belts 116, and partition plates 118 are evenly spaced on the transport plate 117. The space between two adjacent partition plates 118 is used to place bundled waste banknotes. It is worth mentioning that two punching holes 1171 are provided on the transport plate 117 between two adjacent partition plates 118, which are used for the punching assembly 300 to punch and invalidate the bundled waste banknotes.

[0035] Furthermore, due to the limitation of the working environment, the discharging line 120 and the feeding line 110 are arranged vertically, and the transfer mechanism 130 is arranged at the starting end of the discharging line 120 and the end of the feeding line 110, so as to transfer the punched bundled waste banknotes transmitted to the end of the feeding line 110 to the starting end of the discharging line 120. The discharging line 120 includes a second transmission motor 121 and at least two second-type transmission rollers 122. In this embodiment, the number of the second-type transmission rollers 122 is two, and the two second-type transmission rollers 122 are connected by a third transmission belt 123. The output end of the second transmission motor 121 is coaxially connected with one of the second-type transmission rollers 122 to drive the third transmission belt 123 to roll, thereby realizing the use of the transmission belt to transport the punched bundled waste banknotes.

[0036] According to the above technical solution, the transfer mechanism 130 includes a transfer motor 131 arranged on the end surface of the cabinet 400 and a clamp 132 arranged on the transfer motor 131. In order to ensure that the bundled waste banknotes are transferred from the feeding line 110 to the discharging line 120, the transfer motor 131 is at least required to drive the clamp 132 to move in the vertical and horizontal directions, thereby realizing the transfer function of the bundled waste banknotes.

[0037] In order to ensure that the bundled waste banknotes are neatly fed into the feeding line 110 to be punched and scrapped, the pushing assembly 200 includes a stacking mechanism 210 arranged at the starting end of the feeding line 110 and a pushing mechanism 220 arranged at the side of the stacking mechanism 210 away from the feeding line 110. The stacking mechanism 210 includes stacking brackets 211 symmetrically arranged on both sides of the first type of transmission roller 112, and blocking plates 212 connecting the stacking brackets 211 on both sides. The inner angle of the stacking bracket 211 is 90° to fit the corners of the bundled waste banknotes. A pushing notch 2121 is provided at one end of the blocking plate 212 close to the feeding line 110. The height of the pushing notch 2121 is slightly higher than the height of a bundle of waste banknotes. The stacking bracket 211 and the blocking plate 212 enclose a feeding space 213 for stacking bundles of waste banknotes. The feeding space 213 can stack a number of bundles of waste banknotes.

[0038] In order to feed the bundled waste banknotes stacked in the feeding space 213 into the feeding line 110, the pushing mechanism 220 includes a pushing motor 221 disposed on the side of the stacking bracket 211 away from the blocking plate 212 and a pushing plate 222 connected to the pushing motor 221. The height of the pushing plate 222 is the same as the height of the bundled waste banknotes disposed at the bottom of the feeding space 213. When the pushing motor 221 drives the pushing plate 222 to push forward, the bundled waste banknotes at the bottom can be directly pushed into the feeding line 110. At the same time, due to the limitation of the pushing notch 2121 at the bottom of the blocking plate 212, when the bundled waste banknotes at the bottom are pushed into the feeding line 110, due to the limitation of the height of the pushing notch 2121, only the bundled waste banknotes at the bottom can be accommodated to pass through, and the penultimate bundle of waste banknotes disposed at the bottom will not be fed into the feeding line 110 due to the blocking effect of the blocking plate 212. As the bundled waste banknotes at the bottom are fed into the feeding line 110, the penultimate bundle of waste banknotes falls due to gravity and becomes the bottom bundle of waste banknotes. The pushing motor 221 and the pushing plate repeat the pushing action to push the bundled waste banknotes into the feeding line 110 for punching and scrapping.

[0039] It is worth emphasizing that the pushing action and the feeding speed of the feeding line 110 should be coordinated to ensure that each time a bundle of waste banknotes is fed into the feeding line 110, it just falls between the adjacent partition plates 118. The above function can be realized by debugging a single-chip microcomputer or other control chip. At the same time, since the feeding line 110 has a certain transmission speed, the bundle of waste banknotes will be against the partition plate 118 to be punched and invalidated.

[0040] In order to achieve the purpose of punching bundled waste banknotes, a punching assembly 300 is also provided on the cabinet 400. The punching assembly 300 is arranged above the feeding line 110. The punching assembly 300 includes a punching mechanism 310 arranged above the feeding line 110, a supporting mechanism 320 and a collecting mechanism 330 arranged below the feeding line 110. The support mechanism 320 includes at least three columns 321 vertically arranged on the feeding line body 110, a top plate 322 arranged at one end of the column 321 away from the feeding line body 110, and a stamping plate 323 arranged between the top plate 322 and the feeding line body 110. In this embodiment, there are four columns 321, which are respectively arranged at the corners of the top plate 322 and the stamping plate 323, and are symmetrically arranged on both sides of the feeding line body 110, so as to support the stamping mechanism 310 arranged on both sides of the top plate 322 and the stamping plate 323. Among them, since a sliding sleeve 324 is provided at the connection between the stamping plate 323 and the column 321, the outer part of which is fixed to the stamping plate 323, and the inner part can slide relative to the column 321, the stamping mechanism 310 can drive the stamping plate 323 to reciprocate along the length direction of the column 321, thereby realizing the stamping function.

[0041] In order to drive the punching plate 323 to reciprocate and realize the punching function, the punching mechanism 310 includes a punching cylinder 311 arranged on the side of the top plate 322 away from the punching plate 323, a punching head 312 arranged between the top plate 322 and the punching plate 323, and a tool male die 313 and a tool female die 314 arranged between the punching plate 323 and the feeding line 110, wherein the output end of the punching cylinder 311 passes through the top plate 322 for installing the punching head 312. The tool male die 313 is arranged on the side of the punching plate 323 close to the feeding line 110 through a connecting plate 315, and the tool female die 314 is arranged on the side of the feeding line 110 away from the tool male die 313, that is, below the feeding line 110. In this embodiment, the tool male die 313 is two punching cylinders, and the tool female die 314 is provided with two perforations 3141 corresponding to the two punching cylinders.

[0042] When the bundled waste banknotes are transported to the punching assembly 300, the punching cylinder 311 drives the punching head 312 to press down, so as to force the punching plate 323 to move downward, thereby driving the cutter male die 313 to punch downward. It is worth noting that the two punching holes 1171 on the transport plate 117 between the adjacent partition plates 118, the cutter male die 313, and the perforation 3141 on the cutter female die 314 are aligned to avoid the cutter male die 313 being unable to punch downward, thereby causing damage to the cutter male die 313. When the cutter male die 313 is successfully punched downward, the waste generated after punching enters the collection mechanism 330 below through the perforation 3141 of the cutter female die 314.

[0043] It should be emphasized that an elastic member 316 is provided at each of the four corners of the connecting plate 315. When the cutter male die 313 is stamped downward, the punch head 312 can be driven upward to reset by the punching hydraulic cylinder. Since the elastic member 316 is compressed during the stamping process, after the stamping is completed, the elastic member 316 has a restoring force, which presses against the connecting plate 315 upward and then presses against the stamping plate 323 to move upward along the axial direction of the column 321 to achieve the reset function, and then prepare for the next stamping. The stamping assembly 300 replaces the manual stamping method, reduces the labor intensity, and improves the stamping efficiency.

[0044] The collecting mechanism 330 includes a slide groove 331 arranged below the tool die 314 and a collecting box 332 arranged at the outlet of the slide groove 331. One end of the slide groove 331 is connected to the end face of the tool die 314 by screwing, and it can form an angle of 45°-60° with the horizontal direction, so that the waste chips falling from the through hole 3141 of the tool die 314 can fall directly into the collecting box 332 through the slide groove 331, avoiding the waste chips from being directly scattered on the ground and causing a dirty working environment.

[0045] In summary, the automated small-sheet waste banknote punching and destruction device proposed in the present invention saves labor and improves the punching efficiency by stacking the bundled waste banknotes in the stacking mechanism, and using the pushing mechanism to push the bundled waste banknotes to the transport component to transport them to the punching mechanism, and using the punching cylinder to punch the bundled waste banknotes on the transport component, and the waste scraps generated fall into the collection mechanism below the transport component to avoid scattering, thereby ensuring the cleanliness of the working environment. Specifically, the stacking mechanism is arranged at the starting end of the transport component, and the pushing mechanism is arranged on one side of the stacking mechanism, and the pushing mechanism is used to push the bundled waste banknotes in the stacking mechanism to the transport component to improve the feeding efficiency. The transport component transports the bundled waste banknotes to the bottom of the punching mechanism, and uses the punching cylinder to punch the bundled waste banknotes, which replaces the manual punching method, reduces the labor intensity of the manual labor, and improves the punching efficiency. The waste scraps after punching fall into the collection mechanism below the transport component to avoid scattering in the working environment, thereby ensuring the cleanliness of the working environment.
