DETAILED DESCRIPTION

Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.
Referring to FIGS. 2 to 4, an embodiment of a paper sheet deposit machine 1 according to the present disclosure is adapted for storing a plurality of paper sheets 901 in a paper sheet storage bag 900. The paper sheet deposit machine 1 includes a paper sheet handling module 10, a paper sheet storage equipment 20 and a housing 30. The paper sheet handling module 10 and the paper sheet storage equipment 20 are at least partially received in the housing 30. The paper sheet handling module 10 includes an inlet 110, an outlet 120, an opening 130, a discrimination unit 150, and an upper conveying path 140 that connects the inlet 110, the discrimination unit 150, the outlet 120 and the opening 130. In this embodiment, the paper sheets 901 are bank notes. In certain embodiments, the paper sheets 901 may be checks or other sheets of paper, and should not be limited by the embodiment of this application.
The discrimination unit 150 is configured to discriminate at least one feature of each of the paper sheets 901, allows the paper sheets 901 that pass the discrimination to be conveyed to the opening 130, and allows the paper sheets 901 that fail to pass the discrimination to be conveyed to the outlet 120. The paper sheet storage equipment 20 has a lower opening 280 that is communicated with the opening 130 of the paper sheet handling module 10. That is, the paper sheets 901 are conveyed along the upper conveying path 140 from the inlet 110 to reach the discrimination unit 150. The paper sheets 901 passing the discrimination would be further conveyed along the upper conveying path 140 to reach the opening 130, and to enter the paper sheet storage equipment 20.
The paper sheet storage equipment 20 includes an inner housing 210 disposed in the housing 30, a temporary storage unit 220, a bag installation unit 230 and a sealing unit 240.
The bag installation unit 230 is disposed inside the inner housing 210, and is adapted for the paper sheet storage bag 900 to be installed thereon. In this embodiment, the bag installation unit 230 are configured as two protrusions (see FIG. 4) adapted for the paper sheet storage bag 900 to be installed (i.e., held) thereon. In certain embodiments, the bag installation unit 50 holds the paper sheet storage bag 900 by clamping, velcroing, buttoning, zippering, etc., and may be changed according to practical requirements.
Referring further to FIGS. 5 to 7, in this embodiment, the paper sheet storage equipment further includes a lower conveying unit 250 connected between the paper sheet handling module 20 and the temporary storage unit 220. The lower conveying unit 250 includes a wheel unit 251, which includes a plurality of friction wheel sets 252 and a deformation wheel set 253 disposed downstream of the friction wheel sets 252. Each of the friction wheel sets 252 includes a driving wheel 2521 and a driven wheel 2522. The deformation wheel set 253 includes two spaced apart first wheels 2531, and a second wheel 2532 disposed between the first wheels 2531 and having a diameter larger than that of each of the first wheels 2531.
Referring to FIGS. 8 to 10, the temporary storage unit 220 includes two supporting plates 221, a limiting member 222, a seat 223, two torsion springs 224. The supporting plates 221 cooperatively define a temporary storage region (TSR) (see FIG. 13) that is spatially communicated with the opening 130. In this embodiment, the lower conveying unit 250 is connected between the opening 130 and the temporary storage region (TSR), allowing the paper sheets 901 to be conveyed through the opening 130 and the lower conveying unit 40 to be disposed at the temporary storage region (TSR) and on the supporting plates 221. Each of the paper sheets 901 passing through the lower conveying unit 250 is conveyed between the driving wheel 2521 and the driven wheel 2522 of each of the friction wheel sets 252 through friction, and is then deformed by the deformation wheel set 253. Specifically, referring to FIG. 7, when one of the paper sheets 901 passes through the deformation wheel set 253, a center portion of the paper sheet 901 is deformed by the second wheel 2532 to form a substantial V shape, thereby increasing the overall toughness of the paper sheet 901, and ensuring each of the paper sheets 901 passing through the deformation wheel set 253 to be more precisely stacked on the supporting plates 221.
In this embodiment, the supporting plates 221 are horizontally spaced apart from each other, and each of the supporting plates 221 is pivotably connected to the seat 223. The torsion springs 224 are connected to the seat 223. Each of the torsion springs 224 has two ends that respectively abut against the seat 223 and a respective one of the supporting plates 221 for biasing a corresponding one of the supporting plates 221 to a horizontal position.
The limiting member 222 is movably connected to the seat 223, and is operable to engage the supporting plates 221 (see FIG. 9 and the upper part of FIG. 10), such that the supporting plate 221 is adapted to support the paper sheets 901, and is operable to disengage the supporting plates 221 (see the lower part of FIG. 10), such that the supporting plates 221 are pressed by the paper sheets 901 and are thus swingable to allow the paper sheets 901 to drop into the paper sheet storage bag 900. In this embodiment, the limiting member 222 is movable in a direction (D) as indicated by an arrow in FIGS. 9 and 10 to disengage the supporting plates 221. Specifically, when the limiting member 222 engages the supporting plates 221, the supporting plates 221 are horizontal and cooperate with each other to support the paper sheets 901. When the limiting member 222 disengages the supporting plates 221, each of the supporting plates 221 is swingable downwardly due to the gravitational force of the paper sheets 901, so that the paper sheets 901 drop into the paper sheet storage bag 900. After the paper sheets 901 separate from the supporting plates 221, the torsion springs 224 bias and return each of the supporting plates 221 to the horizontal position.
In this embodiment, each of the supporting plates 221 has a protrusion 2211. The limiting member 222 has two spaced apart horizontal slots 2221 each having an open end, and the horizontal slots 2221 are opened in the same direction. The limiting member 222 is operable to move between an engaging position (see FIG. 9 and the upper part of FIG. 10), where the horizontal slots 2221 of the limiting member 222 respectively engage the protrusions 2211 of the supporting plates 221, and a disengaging position (see the lower part of FIG. 10), where the horizontal slots 2221 of the limiting member 222 are disengaged from the protrusions 2211 of the supporting plates 221. The limiting member 222 may be actuated by a solenoid actuator 228, which may be replaced by other actuating mechanism based on actual requirements.
Referring to FIG. 11, in a variation of this embodiment, each of the supporting plates 221 is formed with a pin hole 2212. The limiting member 222 has two spaced apart pins 2222. The limiting member 222 is operable to move between the engaging position, where the pins 2222 of the limiting member 222 are respectively inserted into the pin holes 2212 of the supporting plates 221 to hold each of the supporting plates 221 at the horizontal position, and a disengaging position, where the pins 2222 of the limiting member 222 are respectively disengaged from the pin holes 2212 of the supporting plates 221. In this embodiment, the limiting member 222 is movable in a direction (D′) as indicated by an arrow in FIG. 11 to disengage the supporting plates 221.
Referring to FIG. 12, in another variation of this embodiment, the limiting member 222 has two spaced apart protrusions 2223. The limiting member 222 is operable to move between the engaging position, where the protrusions 2223 of the limiting member 222 are respectively underneath the supporting plates 221 for blocking each of the supporting plates 221 from downward pivotal movement from the horizontal position, and the disengaging position, where the limiting member 222 is horizontally spaced apart from the supporting plates 221 to allow the supporting plates 221 to pivot downwardly. In this embodiment, the limiting member 222 is movable in a direction (D″) as indicated by an arrow in FIG. 12 to disengage the supporting plates 21.
Referring to FIGS. 4 and 8, the temporary storage unit 220 further includes an extendable member 225 that is connected between the inner housing 210 and the seat 223. In this embodiment, the extendable member 225 has a deployable scissor structure, and may be changed according to practical requirements. In this embodiment, the temporary storage unit 220 further includes a roller 226 that is connected to the inner housing 210, and a film 227 that is rolled on the roller 226 and that has an end connected to the seat 223. The roller 226 is operable by an actuator (not shown) to release the film 227 from the roller 226, the limiting member 222, the supporting plates 221 and the torsion springs 224 to move downwardly, or to roll the film 227 thereon so as to pull the seat 223, the limiting member 222, the supporting plates 221 and the torsion springs 224 to move upwardly. Since the extendable member 225 has one end connected to the seat 223, the extendable member 225 would be extended when the seat 223 is moved downwardly. In other words, the extendable member 225 is operable by the rolling or unrolling of the roller 226 to vertically move the seat 223, the limiting member 222, the supporting plates 221 and the torsion springs 224 above or in the paper sheet storage bag 900. The purpose of the abovementioned vertical movement is to adjust the altitude of the supporting plates 221 according to the amount of paper sheets 901 contained in the paper sheet storage bag 900. The film 227 separates the paper sheets 901 from the extendable member 225 to prevent the paper sheets 901 from being clamped by the extendable member 225. Besides being extendable, the extendable member 225 also has superior mechanical strength.
Referring to FIG. 4, the sealing unit 240 is disposed on the inner housing 210, and includes a tab 241 that is disposed adjacent to an upper end of the paper sheet storage bag 900, and a heating member 242 that is operable to heat the tab 241. When the tab 241 is heated by the heating member 242, it is operable to abut against and seal a bag opening 910 of the paper sheet storage bag 900 by heat sealing.
Referring to FIGS. 13 to 18, the paper sheet storage equipment 20 further includes an extendable unit 260 that is disposed above the supporting plates 21, and a sensor 270 that is disposed at a lower end of the extendable unit 260. The sensor 270 may be an infrared sensor configured to measure the amount of paper sheets 901 stacked on the supporting plates 21, thereby ensuring enough temporary storage region (TSR) for storing the paper sheets 901. FIG. 14 shows that the paper sheets 901 are starting to be stacked on the supporting plates 21. FIG. 15 shows that the extendable member 225 extends downwardly with more paper sheets 901 are stacked on the supporting plates 21. After a certain amount of paper sheets 901 are stacked on the supporting plates 21 (see FIG. 15), the limiting member 22 is moved to the disengaging position to allow some of the paper sheets 901 to drop into the paper sheet storage bag 900 (see FIG. 16). Specifically, since the weight of the paper sheets 901 stacked on the supporting plates 21 is greater than the weight that the torsion springs 224 can withstand, the supporting plates 21 is downwardly swingable due to the weight of the paper sheets 901 stacked thereon, thereby allowing some of the paper sheets 901 to drop into the paper sheet storage bag 900, and the supporting plates 21 will be biased by the torsion springs 224 to return to the horizontal position when the weight of the paper sheets 901 remaining on the supporting plates 21 is less than the weight that the torsion springs 224 can withstand. To ensure that there are certain amount of paper sheets 901 left on the supporting plates 21, the sensor 270 senses that if there is any paper sheet 901 left on the supporting plates 21, and the extendable unit 260 will be driven to a predetermined altitude. Meanwhile, the extendable member 225 is driven to move the supporting plates 21 upwardly, allowing the paper sheets 901 left on the supporting plates 21 to abut against the extendable unit 260. Since the extendable unit 260 is fixed at the predetermined altitude, and the supporting plates 21 are continuously moved upward by the extendable member 225, the paper sheets 901 left on the supporting plates 21 will abut against the extendable unit 260, allowing the supporting plates 21 to rotate downwardly to form an opening for the paper sheets 901 to pass through the opening and drop into the paper sheet storage bag 900.
The limiting member 222 and the supporting plates 221 of this disclosure provide a simplified and efficient mechanism to control the paper sheets 901 to be stacked on the supporting plates 221 or to be released into the paper sheet storage bag 900.
In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiments. It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details.
