[0032] The cash bag device provided by the present invention is usually applied to devices such as self-service payment machines and self-service deposit / withdrawal machines. Such devices generally have an upper and a lower structure. The upper machine realizes functions such as card reading, banknote verification, banknote counting, banknote receiving, and control, and the main function of the lower machine is to store banknotes. The cash bag device is installed in the safe of the lower machine. When the user performs operations such as payment and deposit, the cash inlet is opened according to the banknote inlet instruction sent by the upper machine, so that the banknotes dropped through the cash inlet of the safe by the upper machine can enter the cash bag, and the cash inlet is closed under the closing instruction sent after the upper machine completes the storage / payment operation. When it is necessary to transport the banknotes in the cash bag out, the cash bag is taken out, and an empty cash bag is installed in the safe to continue working. However, for the current cash bag device, in order to control the opening / closing of the cash inlet on the cash bag, an electronic control unit is provided on the cash bag, which poses a hidden danger of the cash bag catching fire due to the heating of electronic components during transportation.

[0033] For the cash bag device provided by the present invention, only a mechanical module is provided on the cash bag for loading and transporting banknotes, and the electronic control unit is fixed in the safe, solving the above-mentioned hidden danger.

[0034] Specifically, the structure of a cash bag device according to an embodiment of the present invention is as Figure 1 shown, and includes: a mounting frame 1, a fixing plate 2, an electronic control unit 3, and a cash bag 4; wherein, the mounting frame 1 is fixed on the fixing plate 2; during use, the mounting frame 1 is used to fix the fixing plate 2 at the top inside the safe of the lower machine, the electronic control unit 3 is arranged on the fixing plate 2, is electrically connected to the upper machine, and is controlled by the upper machine; the cash bag 4 is installed at the bottom of the fixing plate 2;

[0035] The cash bag 4 includes: a mechanical module 41, a cash bag cover plate 42, a frame 43, and a cash bag body 44; the mechanical module 41 is arranged in the cavity of the cash bag cover plate 42; the cash bag cover plate 42 is embedded in the upper part of the frame 43 and is fixed to the frame 43 through a cash bag lock 45; the lower part of the frame 43 sleeves the top opening of the cash bag body 44, and the lower part of the frame 43 and the top opening of the cash bag body 44 are assembled and fixed;

[0036] The fixing plate 2 and the cash bag cover plate 42 have cash inlets at corresponding positions of the cash inlet at the top of the safe;

[0037] The electronic control unit 3 includes: a control module 31 and a sliding module 32; the mechanical module 41 includes: an elastic component 411 and an opening / closing component 412;

[0038] The control module 31 controls the movement of the sliding module 32; the sliding module 32 moves forward to push the elastic component 411 to drive the opening / closing component 412 to move and open the cash inlet; the sliding module 32 moves backward, the elastic component 411 rebounds, and drives the opening / closing component 412 to move and close the cash inlet.

[0039] Here, the lower part of the frame 43 and the top opening of the banknote bag body 44 are assembled and fixed. An inner edge strip can be used to flatten the top edge of the banknote bag body against the inner side of the lower part of the frame and fixed with screws.

[0040] When the banknote bag is installed on the fixed plate, the sliding module of the electronic control unit contacts the elastic component of the banknote bag. When the sliding module slides forward, it can push the elastic component forward, and then drive the opening and closing component to open the banknote inlet; when the sliding module slides backward, the thrust of the sliding module on the elastic component can be cancelled, and by virtue of the rebound of the elastic component, the opening and closing component is driven to close the banknote inlet. At the same time, the sliding module of the electronic control unit only contacts the elastic component of the banknote bag. When the banknote bag is taken out, the electronic control unit is separated from the banknote bag, and the elastic component remains unchanged without being stressed, so that the banknote inlet remains closed. That is, the banknote bag device realizes the function of cooperating with devices such as self-service payment machines and self-service deposit / withdrawal machines to complete banknote input, and also realizes the function of isolating personnel and banknotes during the cash transportation process.

[0041] When the banknotes in the banknote bag need to be taken out at the destination, the cash collector uses a key to open the banknote bag lock, and then the banknote bag cover plate can be pulled out from the frame to take out the banknotes. In order to completely avoid having electronic components on the banknote bag, the banknote bag lock is realized by a mechanical lock, which can be set on the frame, and a groove or through hole is set at the corresponding position of the banknote bag cover plate for the mechanical lock tongue.

[0043] A handle is arranged on the front side of the frame body 432 to facilitate pulling out or pushing in the banknote bag.

[0044] In another possible implementation, positioning pins are arranged on the slide grooves, and pin holes are arranged at the corresponding positions of the slide rails.

[0045] When installing the banknote bag device, when the positioning pin is snapped into the pin hole, it indicates that the banknote inlet of the safe and the banknote bag device are aligned and the banknote bag is installed in place. That is, setting the positioning pin helps to quickly align the safe and the banknote bag device.

[0046] In another possible implementation, the pressing frame 431 is made of PC board, the frame body 432 is made of aluminum alloy strip; the banknote bag cover plate 42 is made of aluminum alloy plate.

[0047] The PC board and the aluminum alloy strip are much lighter in weight than steel. Therefore, in this implementation, the PC board and the aluminum alloy strip are used to replace the steel used in most current banknote bag devices, which has the advantage of being light and easy to transport.

[0048] In another possible implementation, the electronic control unit 3 further includes a card reader 33, which is fixed to the rear edge of the fixing plate 2; correspondingly, an electronic tag 433 is provided at a corresponding position of the frame 43.

[0049] After the cash bag is installed in place, the card reader reads the electronic tag of the cash bag, and after the reading is completed, the cash bag is replaced and reset.

[0050] In another possible implementation, the electronic control unit 3 further includes an electromagnetic lock 34, which is installed on the fixing plate 2, and through holes are provided at positions on the fixing plate 2 and the frame 43 corresponding to the lock tongue of the electromagnetic lock.

[0051] Here, the electromagnetic lock is used to lock the cash bag to the fixing plate to prevent the safe from being illegally opened to take out the cash bag. When taking out the cash bag, the electromagnetic lock can be opened to draw out the cash bag.

[0056] The slide rail 4111 is arranged on the bottom plate 413, one end is tangent to the rear edge of the bottom plate 413, and the other end abuts against the rear side edge of the cash inlet of the bottom plate 413; the slide rod 4112 is fixedly arranged in the middle of the track of the slide rail 4111 and is parallel to the track, and the slider B 4114 is sleeved on the slide rod 4112 and supported by the slide rail 4111; the spring 4113 is sleeved on the slide rod 4112, and one end abuts against the slider B 4114, and the other end abuts against the rear side edge of the cash inlet of the bottom plate 413;

[0057] The turntable shaft 4122 is arranged on the bottom plate 413 and symmetrically distributed on both sides of the slide rail 4111; a turntable 4121 is sleeved on each of the two turntable shafts 4122, and notches are arranged at the outer sides of the two turntables 4121 on the bottom plate 413; two through holes penetrating through the turntable 4121 and the bottom plate 413 are formed at the intersections of the two notches and the notches on the two turntables respectively; two cylinders are fixed on the banknote inlet plate 4123, and the two cylinders are respectively inserted upward into the two intersecting through holes.

[0058] The slider B 4114 is rotatably connected to the opposite sides of the notches of the two turntables 4121 through two connecting rods respectively.

[0059] In another possible implementation, the mechanical module 41 further includes a safety lock 414, and the safety lock 414 includes an insurance block 4141, a locking button 4142, and a release button 4143; the release button 4143 of 414 is fixed to one end of the insurance block 4141 through a connecting rod; when the banknote inlet is closed, the locking button 4142 is pushed, and the insurance block 4141 moves along with the locking button 4142 until the buckle arranged on the insurance block 4141 enters the bayonet arranged at the corresponding position of the bottom plate 413. At this time, the insurance block 4141 blocks the movement track of the notch of the turntable 4121 behind it and abuts against the top end of the notch of the turntable 4121, preventing the turntable 4121 from rotating; the release button 4143 is toggled, the insurance block 4141 is driven to move by the connecting rod to disengage the buckle from the bayonet, and the insurance block 4141 is pushed forward to retreat from the movement track of the notch of the turntable 4121, releasing the block, and then the locking button 4142 is pushed to reset.

[0060] The installation and use process of the above banknote bag device is described below.

[0061] When installing the banknote bag device, the fixing plate 2 is fixedly connected to the top of the safe through the mounting frame 1, and the electronic control unit 3 is electrically connected to the upper machine, and the electronic control unit 3 is controlled by the upper machine.

[0062] The operation of completing one-time banknote loading by using the banknote bag device is as follows: The motor drive board 314 receives the banknote receiving instruction transmitted from the upper machine, drives the motor 313 to rotate forward, drives the slider A 321 and the push rod 323 to move forward through the transmission shaft 315, further pushes the slider B 4114 to move forward, compresses the spring 4113, and drives the connecting rod to drive the turntable to rotate, so that the banknote loading board 4123 moves backward until the banknote inlet is opened. The motor drive board 314 receives the signal of the photoelectric detection switch 35 and controls the motor 313 to stop rotating. After the banknotes enter the banknote bag body 4 through the banknote inlet, the upper machine transmits a closing instruction to the motor drive board 314. The motor drive board 314 drives the motor to rotate in reverse, drives the slider A 321 and the push rod 323 to move backward through the transmission shaft 315. The spring 4113 rebounds and pushes the slider B 4114 to move backward with the push rod 323, and then drags the connecting rod to drive the turntable to rotate, so that the banknote loading board 4123 moves forward until the banknote inlet is closed. The motor drive board 314 receives the signal of the photoelectric detection switch 35 and controls the motor 313 to stop rotating.

[0063] It can be seen that in addition to performing the banknote loading operation, in order to prevent the banknotes from being taken out from the banknote inlet, the banknote inlet remains closed, that is, the banknote inlet only allows banknotes to enter and prohibits taking out banknotes from the banknote inlet.

[0064] The operation of completing one-time banknote withdrawal by using the banknote bag device described in this embodiment is as follows:

[0065] First, take out the banknote bag. Specifically, push the locking button 4142, and the insurance block 4141 is pushed to move with the locking button 4142 until the buckle provided on the insurance block 4141 enters the bayonet provided at the corresponding position of the bottom plate 413, preventing the turntable 4121 from rotating and locking the banknote inlet; operate the upper machine to control the electromagnetic lock 34 to unlock, hold the handle and pull out the banknote bag 4 forward, so that the slide rail of the banknote bag 4 disengages from the chute on both sides of the fixed plate 2.

[0066] Second, load an empty banknote bag. Specifically, pull the release button 4143, drive the insurance block 4141 to move through the connecting rod so that the buckle disengages from the bayonet, and push the insurance block 4141 forward to move away from the slot trajectory of the turntable 4121, push the locking button 4142 to reset, and then unlock the banknote inlet; hold the handle and push the slide rail of the banknote bag 4 into the chute on both sides of the fixed plate 2 until the positioning pin on the chute snaps into the pin hole at the corresponding position of the slide rail; operate the upper machine to control the card reader 33 to read the electronic tag 433 and control the electromagnetic lock 34 to lock.

[0067] Finally, transport the taken-out banknote bag 4 to the destination. The banknote withdrawal personnel use the key to open the banknote bag lock 45, pull the banknote bag cover 42 away from the frame 43, take out the banknotes, then put the banknote bag cover 42 into the frame 43, lock the banknote bag lock 45, and complete one-time banknote withdrawal operation.

[0068] The above are only the preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
