Description

Technical Field

[0001] The present invention relates to a system for removing the bundling straps of bundled sheet materials, belonging to the technical field of sheet material packaging. Background Art

[0002] Common sheet materials include valuable securities such as banknotes, vouchers, checks, etc. During the packaging process, one hundred sheet materials are neatly aligned and stacked into a stack, and then tied into a bundle with a single bundling strap, which is called a "Bai Bao" here, and the bundling strap used here is called the "Bai Bao bundling strap". Every ten stacks of "Bai Bao" are stacked into a stack and tied with multiple bundling straps, which is called a "Qian Bao" here, and the bundling strap used here is called the "Qian Bao bundling strap". The bundling straps in the present invention are bundling straps of various materials. Disassembly refers to the process of removing the bundling straps of the bundled sheet materials so that the sheet materials are in a free state.

[0003] Currently, units such as sheet material processing centers and sheet material production enterprises are faced with a large number of sheet material sorting operations. Among them, the disassembly of bundled sheet materials is completely completed manually using tools such as knives, which has a high labor intensity, low efficiency, and certain potential safety hazards, such as cuts and scratches.

[0004] In the Chinese utility model with the patent number ZL 202120500598.6, a core disassembly device is disclosed, which includes a power plate capable of moving up and down, at least two disassembly components spaced on the power plate, and a positioning mold for installing a whole-round core; the positioning mold can sequentially move the whole-round core below at least two disassembly components for at least two disassembly components to disassemble; each disassembly component includes two wedge-shaped structures spaced apart, one end of the wedge-shaped structure is connected to the power plate, and the other end of the wedge-shaped structure is a free end and is wedge-shaped and is used to insert into the core slot to expand the core slot; the two wedge-shaped structures of each disassembly component can be inserted into the two core slots of the whole-round core under the drive of the power plate to disassemble the whole-round core into two parts; the positions of all wedge-shaped structures in the circumferential direction are different, and are used to insert into all the core slots of a whole-round core one by one.

[0005] However, since the bundling of sheet materials uses multiple crossed bundling straps, for automatic disassembly, it is necessary to consider not damaging the sheet materials (such as valuable securities), and also to consider that all multiple bundling straps need to be completely cut, and after unpacking, the sheet materials still need to be neatly stacked and cannot be scattered.

[0053] The technical content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] First of all, it should be noted that the bundling sheet material disassembling system provided by the embodiments of the present invention can be used for disassembling various sheet materials, such as vouchers, banknotes, checks, etc. For the convenience of description, in the embodiments of the present invention, the bundling sheet materials are taken as an example of thousand-packs or hundred-packs for illustration, but this does not constitute a limitation to the present invention.

[0055] As Figures 1(a) to 1(c) shown, the first embodiment of the present invention discloses a bundling sheet material disassembling system, including a storage hopper 1, a pusher mechanism 2, a sheet translation platform 3, a wide-edge cutter 4, a narrow-edge cutter 5, a sheet bundling belt removing device 6, a sheet bundling cutter 7, a sheet feeding mechanism 8, a clamping and rotating mechanism 9, a side alignment mechanism 10, a temporary storage and sorting mechanism 11, a loose sheet narrow-edge sorting mechanism 12, a stacking lifting mechanism 13, a translation trolley 14, and a stacking lifting mechanism 15.

[0056] As Figure 2 shown, the storage hopper 1 is a hopper with openings at both ends, and multiple thousand-packs can be accommodated inside. It is vertically arranged at the upper part of the system, and its bottom is connected to the pusher mechanism 2.

[0057] As Figure 3 shown, the pusher mechanism 2 includes a pusher mechanism frame 201, a temporary storage plate 202, a pusher bin 203, a telescopic push rod 204, and a slide rail 205. The temporary storage plate 202 is installed on the top surface of the pusher bin 203. The distance between the temporary storage plate 202 and the bottom of the pusher bin 203 is not greater than the height of the thousand-pack, and it is connected to the pusher mechanism frame 201 through the slide rail 205. The telescopic push rod 204 is a pneumatic telescopic rod, and the telescopic push rod 204 is connected to the pusher bin 203.

[0058] The telescopic push rod 204 pushes the material pushing bin 203 to reciprocate in the horizontal plane, so as to push the bales falling from the bottom of the storage hopper 1 into the material pushing bin 203 to the processing position of the sheet translation platform 3. During this pushing process, the temporary storage plate 202 can block the vertical movement of other bales in the storage hopper 1 to prevent misoperation of the bales.

[0059] As shown in FIGS. 4(a) and 4(b), the sheet translation platform 3 includes a material disassembling table 301, a wide-side baffle 302, a narrow-side baffle 303, a sheet translation push plate 304, and a narrow-side baffle translation device 305.

[0060] The bales pushed out from the pushing mechanism 2 fall into the material disassembling table 301 and are positioned on the rectangular material disassembling table 301. The wide-side baffle 302 and the narrow-side baffle 303 are respectively arranged on adjacent sides of the material disassembling table 301 to block one side of the wide side and the narrow side of the bales, and wide-side cutting knives 4 and narrow-side cutting knives 5 are respectively arranged on the other opposite sides. Both the wide-side baffle 302 and the narrow-side baffle 303 are vertically arranged sheet-like members, having an abutting surface 30 (detailed later) adapted to the outer contours of the extrusion surface 5111 and the outer inclined surface 5112, guiding the bales subjected to their extrusion to deform in the corresponding tool rest grooves, so that the positions on the opposite sides of the bales are concavely deformed and separated from the binding straps, thus creating sufficient gaps to facilitate the cutting of the binding straps.

[0061] The narrow-side baffle translation device 305 is a pneumatic device for moving the narrow-side baffle 303 away, so that the sheet translation push plate 304 can push the bales with the binding straps removed into the sheet distribution mechanism 8.

[0062] The wide-side cutting knife 4 and the narrow-side cutting knife 5 have exactly the same mechanical principle and action process, and only differ in the detailed dimensions and installation methods, and are respectively used to cut the binding straps tied on the long side and the short side of the rectangular sheet material. Therefore, the working principle of the narrow-side cutting knife 5 is mainly described.

[0063] As Figure 5 shown, the wide-side cutting knife 4 includes a wide-side knife body press head 401, a wide-side cutting knife assembly 402, a wide-side pressing drive device 403, and a wide-side cutting knife drive device 404. The wide-side cutting knife 4 is used to cut the binding strap on the wide side of the bale, and the specific structure and working principle are referred to the relevant description of the narrow-side cutting knife 5 in the following text.

[0064] As shown in FIGS. 6(a) and 6(b), the narrow-edge cutter 5 includes a narrow-edge cutter body press head 51, a narrow-edge cutter assembly 52, a narrow-edge pressing drive device 53, a narrow-edge cutter drive device 54, and a connecting plate 59. The narrow-edge cutter body press head 51, the narrow-edge cutter assembly 52, and the narrow-edge cutter drive device 54 are all mounted on the connecting plate 59. The narrow-edge pressing drive device 53 is relatively fixedly connected to the connecting plate 59 to enable the narrow-edge pressing drive device 53 to drive the connecting plate 59 to move in the first direction, so that the narrow-edge cutter body press head 51 can move towards or retract from the sheet material, while there is no relative displacement between the narrow-edge cutter assembly 52 and the narrow-edge cutter body press head 51 in the first direction.

[0065] The narrow-edge pressing drive device 53 is a cylinder, and the direction of its expansion and contraction is the first direction; the narrow-edge cutter drive device 54 is a cylinder, and the direction of its expansion and contraction is the second direction.

[0066] The narrow-edge cutter body press head 51 arranged along the second direction includes two identical strip-shaped members 511 with a generally trapezoidal cross-section and a U-shaped groove member 512. The groove member 512 encloses a cutter body groove 515 parallel to the second direction.

[0067] As shown in FIG. 6(b), the strip-shaped member 511 includes a pressing surface 5111, an outer inclined surface 5112, an inner vertical surface 5113, and a connecting surface 5114. The pressing surfaces 5111 of the two strip-shaped members 511 are perpendicular to the first direction and face the Qianbao, for abutting against and clamping the Qianbao (the bundled sheet material).

[0068] The inner vertical surfaces 5113 of the two strip-shaped members 511 are arranged opposite to each other. The inner vertical surface 5113 extends from one side of the pressing surface 5111 along a direction parallel to the first direction, so as to form a cutter holder groove 514 parallel to the second direction between the two inner vertical surfaces 5113.

[0069] Among them, the connecting surface 5114 of the strip-shaped member 511 is parallel to the extrusion surface 5111 and connects to the top end of the groove-shaped member 512. The connecting surface 5114 extends perpendicularly from the inner vertical surface 5113 in the first direction towards the outer inclined surface 5112 and connects to the inner surface of the groove-shaped member 512. The outer inclined surface 5112 of the strip-shaped member 511 connects the extrusion surface 5111 and the outer surface of the groove-shaped member 512. The outer inclined surface 5112 is a sloped surface that gradually extends away from the inner vertical surface 5113 from the extrusion surface 5111, such that the cross-section of the two strip-shaped members 511 shows that the dimension in the second direction (perpendicular to the first direction) gradually expands from the extrusion surface 5111 to the outer surface of the groove-shaped member 512. Therefore, the narrow-edge cutter head 51 has a cross-sectional profile similar to a wedge shape, and the extrusion end face close to the bale is the tip position of the wedge. Moreover, the outer inclined surface 5112 is not limited to a planar surface and can be various suitable surface shapes such as a stepped surface or an arc surface, as long as it can achieve that when the sheet material is pressed on the outer inclined surfaces 5112 of the two strip-shaped members 511, the sheet material shows a trumpet-shaped deformation. Such a design is suitable for processing multiple sheets of material at one time and will not cause creases on the sheet material. Therefore, it can improve the processing efficiency without damaging the sheet material.

[0070] Each strip-shaped member 511 is also provided with a narrow-edge cutting groove 513. The narrow-edge cutting groove 513 extends from the extrusion surface 5111 towards the connecting surface 5114. Therefore, the two narrow-edge cutting grooves 513 and the tool holder groove 514 form a cross shape. The position of the narrow-edge cutting groove 513 in the second direction is set according to the position of the binding tape of the sheet material actually to be processed. The dimension of the strip-shaped member 511 in the second direction (simply referred to as "the length of the strip-shaped member") matches the dimension of the sheet material (in the state of being abutted by the narrow-edge cutter head 51) in the second direction (simply referred to as "the length of the sheet material"), and the distance from the narrow-edge cutting groove 513 to the side surface of the strip-shaped member 511 facing the narrow-edge cutter driving device 54 is equal to the distance from the binding tape to the corresponding side of the sheet material. Therefore, when the bale is positioned in the material removal table 301 by the sheet translation platform 3, the binding tape on the narrow edge of the bale will be received in the narrow-edge cutting groove 513.

[0071] The distance D3 between the bottom surface of the narrow-edge cutting groove 513 (the plane shown by the dotted line in Fig. 6(a)) and the extrusion surface 5111 in the first direction is less than the distance D4 between the connecting surface 5114 and the extrusion surface 5111 in the first direction. In this way, when the sheet material is deformed by the extrusion of the extrusion surface 5111 and the outer inclined surface 5112, the binding tape is limited to the bottom surfaces of the two narrow-edge cutting grooves 513, and the sheet material is limited to the outer surfaces of the extrusion surface 5111 and the outer inclined surface 5112. That is, the binding tape is separated from the sheet material.

[0072] The narrow-edge cutting tool assembly 52 includes a narrow-edge tool body 521 and a narrow-edge tool holder 522. The narrow-edge tool holder 522 is fixed to the narrow-edge tool body 521. The narrow-edge cutting tool assembly 52 is designed such that the narrow-edge tool body 521 is received in the tool body groove 515 and the narrow-edge tool holder 522 is received in the tool holder groove 514. Therefore, the narrow-edge tool body 521 can reciprocate in the second direction along the tool body groove 515 to drive the narrow-edge tool holder 522 to reciprocate in the second direction along the tool holder groove 514.

[0073] Cutting blades are provided on the distal surface of the narrow-edge tool holder 522 in the second direction for cutting the binding straps embedded in the narrow-edge cutting groove 513. The cutting blades can be of various shapes. For example, they can be single-piece straight blades or rotary blades, etc., as long as they are suitable for cutting the binding straps. Since the binding straps are limited by the bottom surfaces of the two narrow-edge cutting grooves 513 and separated from the sheet material, and the distance D3 is less than the distance D4, the blades moving in the tool holder groove 514 can cut only the binding straps without damaging the sheet material.

[0074] When the bale is positioned in the untying table 301 by the sheet translation platform 3, the narrow-edge cutting groove 513 is automatically aligned with the binding straps on the narrow edge of the bale. At this time, the pneumatic narrow-edge pressing drive device 53 drives the narrow-edge tool body press head 51, so that the narrow-edge tool body press head 51 presses against the narrow edge of the bale. In cooperation with the concave notch of the narrow-edge baffle 303 on the opposite side of the bale, the binding straps are separated from the bale and embedded in the narrow-edge cutting groove 513; similarly, the pneumatic narrow-edge cutting tool drive device 54 drives the narrow-edge cutting tool assembly 52 to cut the binding straps in the narrow-edge cutting groove 513.

[0075] As Figure 7 shown, the sheet binding strap removing device 6 includes a translation drive device 601 and a negative pressure air head 602. The cut binding straps on the bale are sucked by the negative pressure air head 602, and a translation drive device 601 is provided thereon for moving the cut binding straps to a designated position for collection.

[0076] As Figure 8 shown, the sheet binding cutter 7 includes a sheet cutting tool assembly 71, a binding strap chuck 72, a sheet cutting tool drive device 73, a sheet tool body press head 74, a sheet pressing drive device 75, and an adjustable limit block 76. The mechanical principle of the sheet binding cutter 7 is generally the same as that of the narrow-edge cutter 5; only a binding strap chuck 72 is added above the cutting tool assembly 71, which can hold the cut binding straps in cooperation with the adjustable limit block 76.

[0077] As Figure 9 and Figure 10As shown, the sheet feeding mechanism 8 includes a pushing bottom plate 801, a pushing plate 802, a sheet extrusion groove 803, and a strapping band discharge port 804. The pushing plate 802 is located above the pushing bottom plate 801 and is relatively movable with respect to the pushing bottom plate 801 to push the sheet material along the pushing bottom plate 801 above the sheet extrusion groove 803. The sheet extrusion groove 803 is located below the pushing bottom plate 801 and extends downward from the upper surface of the pushing bottom plate 801. The strapping band discharge port 804 is located on the pushing bottom plate 801 and communicates with the sheet extrusion groove 803.

[0078] The pushing plate 802 can push the bales along its pushing bottom plate 801 to the bale strapping band cutting position, and then continue to push the bales into the temporary storage and sorting mechanism 11. The sheet extrusion groove 803 cooperates with the sheet strapping cutter 7 to separate the bale strapping band from the surface of the bale, and then the bale strapping band is cut by the sheet strapping cutter 7, and one end of the cut strapping band is firmly clamped by the strapping band chuck 72. As the sheet strapping cutter 7 moves, one end of the strapping band is lifted off the surface of the bale; after the scattered sheet materials of the bale are pushed into the temporary storage and sorting mechanism 11, the clamped end is first released by the strapping band chuck 72, and then the strapping band is discharged from the strapping band discharge port 804 by compressed air.

[0079] As shown in FIGS. 11(a) and 11(b), the clamping and rotating mechanism 9 includes a clamping frame 901, a clamping driving device 902, a rotating driving device 903, and a clamping adjustment mechanism 904. The clamping frame 901 is composed of two relatively movable clamping plates. The bales pushed by the sheet translation push plate 304 enter between the two clamping plates. The clamping and rotating mechanism 9 has two pneumatic driving devices, namely the clamping driving device 902 and the rotating driving device 903, which are responsible for the clamping and rotating actions of the clamping and rotating mechanism. The function of rotation is to rotate the bale 180 degrees when the direction of the bales inside the bale is opposite to the direction of the preset processing position to adjust its direction to conform to the preset. The clamping driving device 902 adjusts the position of its rotation center through the clamping adjustment mechanism 904 to adapt to banknotes of different specifications. The specific clamping adjustment mechanism 904 is a telescopic mechanism controlled by a handwheel.

[0080] The distance between the bottom of the clamping frame 901 and the bottom of the bale is slightly higher than the height of a single-pack bale, so that just the bottom layer of bales can be pushed by the sheet separation push plate 801 to the position of the placement table 802, while the upper layer of bales is limited in position by the clamping frame 901 and cannot move.

[0081] As Figure 12 shown, the side alignment mechanism 10 can align the bales with the removal of the strapping band along the narrow side, facilitating subsequent processing.

[0082] As Figure 13As shown, the temporary storage and sorting mechanism 11 can sort and align the sheet materials in each bundle that have been disassembled along the long side, and then let them fall into the stacking and lifting mechanism 13 below.

[0083] As Figure 14 and Figure 15 shown, the loose sheet narrow-side sorting mechanism 12 aligns the narrow sides of the sheet materials stacked in the stacking and lifting mechanism 13; the lifting forks of the stacking and lifting mechanism 13 gradually move downward as the sheet materials stacked on it increase, and gradually enter the basket enclosed by the fork teeth of the translation trolley 14, and finally fall below the bearing surface of the translation trolley 14. Therefore, the translation trolley 14 naturally bears the stacked sheet materials.

[0084] As Figure 16 shown, the translation trolley 14 can translate the stacked sheet materials to directly above the bearing fork teeth of the stacking and lifting mechanism 15; immediately afterwards, the lifting forks of the stacking and lifting mechanism 13 return to their top positions to prepare to receive new sheet materials.

[0085] As Figure 17 shown, the stacking and lifting mechanism 15 lifts the stacked sheet materials to a specified height; immediately afterwards, the translation trolley 14 returns to the position directly below the stacking and lifting mechanism 13 to prepare to transport the next cart of sheet materials.

[0086] By repeating this cycle, the disassembly process of all the bundled sheet materials can be completed.

[0087] The above has described in detail the disassembly system for bundled sheet materials provided by the present invention. For those of ordinary skill in the art, any obvious changes made to it without departing from the essence of the present invention will constitute an infringement of the patent right of the present invention and will bear corresponding legal responsibilities.
