Description

Card transport device

The invention relates to a conveying device, in particular to a card conveying device.

With the rise of plastic currency that does not require the use of cash, and the increasing application of electronic payment, many countries continue to promote the use of stored-value cards to take public transportation to speed up the speed of passengers entering and exiting stations to ease the flow of people. At the same time, these stored-value cards can also be used for electronic payment in stores, scenic spots, or other places, allowing users to travel around the world with one card and improving convenience. Most of these stored-value cards are purchased through automatic vending machines to achieve unmanned sales and greatly save labor costs.

After the user pays for the stored-value card at the vending machine, the stacked stored-value cards are output one at a time through the card output device of the vending machine. However, the traditional card output device usually uses a pulley mechanism as the main transmission method, and the tension needs to be adjusted frequently to keep the belt running normally. It is difficult to maintain and disassemble. In order to ensure that only one card is output at a time, in fact, even if the power supply is stopped, the motor will still rotate due to its own inertia, causing the mechanism to continue to move and send out multiple cards, or the card is in the position of being conveyed but not sent out after the mechanism stops, causing the card to be easily blocked and malfunction.

Therefore, the object of the present invention is to provide a card conveying device which can overcome the aforementioned problems.

Therefore, the card conveying device of the present invention is used for conveying a plurality of stacked cards, and includes a main body unit, a transmission unit, and a conveying unit. The main body unit includes two side supports horizontally spaced apart from each other, and a seat connecting the side supports and forming a slot. The side supports and the seat cooperate with each other to define an installation space communicating with the slot.

The transmission unit includes a motor arranged in the installation space, a gear set arranged on the outer surface of one side bracket and driven by the motor, a driven gear driven by the gear set, a driving pulley driven by the gear set, a driven pulley pivotally arranged on the side bracket, and a transmission belt arranged on the driving pulley and the driven pulley.

The conveying unit includes a rotating shaft pivotally arranged on the side brackets and one end of which is provided by the driven gear, a sleeve arranged on the rotating shaft, a roller pivotally arranged on the shaft sleeve and located below the slot, a clutch mechanism arranged in the installation space and capable of controlling and interlocking the rotating shaft and the roller, and a card feeding mechanism arranged on the bearing seat and dynamically connected to the driven pulley. Due to the slotted projection, the clutch mechanism has a casing that is passed through by the rotating shaft and is arranged on the main body unit, a pivot piece that is arranged on the rotating shaft and forms a plurality of positioning grooves on its surface and cooperates with the casing to define an inner space, an electromagnetic coil that is arranged in the inner space, a clutch piece that surrounds the rotating shaft and is adjacent to the roller and is spaced from the pivot piece, and a plurality of positioning posts that pass through the clutch piece and the roller and extend toward the pivot piece.

The effect of the present invention is that most of the transmission unit uses gears to transmit power, which can avoid the problems of the traditional pulley mechanism. On the other hand, when the electromagnetic coil is energized, it can attract the clutch plate against the pivot plate, and make the positioning posts respectively inserted in the positioning grooves, so that the clutch plate and the roller can be driven to rotate by the rotating shaft. The rotating shaft does not drive the roller, and the clutch mechanism connects or disconnects the power connection between the roller and the rotating shaft by energizing and disconnecting the power. The stroke is short (the distance between the clutch plate and the pivot plate) and can respond quickly, thereby accurately controlling the delivery of cards.

It should be noted that, in order to make the drawing larger and easier to explain, the surrounding blocking wall 14 and the front blocking wall 15 are not shown in other drawings except FIG. 1 .

Referring to Fig. 2, Fig. 3, and Fig. 4, the transmission unit 2 includes a motor 21 arranged in the installation space 181, a gear set 22 arranged on the outer surface of one side bracket 11 and driven by the motor 21, a driven gear 23 driven by the gear set 22, a driving pulley 24 driven by the gear set 22, a driven pulley 25 pivotally arranged on the side bracket 11, a driven pulley 25 arranged on the driving pulley 24 and the driven pulley Drive belt 26 on the 25, and one can adjust position along front and rear and end presses against this idle pulley 27 of this drive belt 26. In general use, the gear set 22 and the driven gear 23 are respectively covered with a quick-detachable outer cover (see FIG. 1 ), but not limited thereto.

Referring to FIG. 3 , FIG. 5 , and FIG. 6 , together with FIG. 4 , it should be noted that the control unit 5 is not shown in FIG. 5 for convenience of description. The conveying unit 3 includes a rotating shaft 31 pivotally arranged on the side brackets 11 and one end of which is provided by the driven gear 23, a bushing 32 set on the rotating shaft 31, a roller 33 pivotally arranged on the bushing 32 and positioned below the slot 121, a clutch mechanism 34 arranged in the installation space 181 and capable of controlling and interlocking the rotating shaft 31 and the roller 33, and a clutch mechanism 34 arranged on the seat 12 and connected to the slave by power. The card feeding mechanism 35 of the moving pulley 25. The bushing 32 enables the components disposed thereon to rotate relative to the shaft 31 , so the shaft 31 does not directly drive the roller 33 to rotate when the shaft 31 rotates. The roller 33 has a wheel body 331 and a protrusion 332 protruding from the outer surface of the wheel body 331 . The bump 332 is made of a material with high friction such as rubber. When the wheel body 331 rotates and the bump 332 passes through the slot 121 , the bump 332 passes through the slot 121 and protrudes into the card holding space 182 .

When the rotating shaft 31 rotates but the electromagnetic coil 345 is not energized, the positioning columns 347 are located outside the positioning grooves 342, so the rotating shaft 31 only drives the pivot piece 344 to rotate synchronously, and does not drive the roller 33 and the clutch plate 346. When the electromagnetic coil 345 is energized, the clutch plate 346 is attracted by the magnetic force of the electromagnetic coil 345, so it moves toward the pivot plate 344 until it abuts against the pivot plate 344, and the positioning posts 347 are also aligned and inserted into the positioning grooves 342 in the aforementioned process.

Referring to Fig. 1, Fig. 3, and Fig. 8, the card feeding mechanism 35 has a mounting seat 351 arranged on the side supports 11 above the through groove 122 of the seat 12 and in front of the roller 33; Wheel 353, an upper guide wheel 354 rotatably arranged on these side supports 11 and positioned above the seat 12 and positioned in front of the supply roller 352, and a lower guide wheel 355 arranged below the seat 12 and positioned at the upper guide wheel 354 below.

The mounting base 351 has a base portion 356 with two ends respectively disposed on the side brackets 11 , and a block portion 357 fixed behind the base portion 356 by injection molding. Both sides of the base portion 356 form an adjustment groove 358 extending vertically and pierced by a screw. The stopper portion 357 and the seat 12 are spaced vertically for a card to pass through. The base part 356 is arranged on the side brackets 11 through four screws, each side is to use two screws, one of the screws passes through the base part 356 and the corresponding side bracket 11, so that the base part 356 is pivoted on the side bracket 11, and the other screw passes through the adjustment slot 358 and the side bracket 11, usually there will be a piece C protruding outward on the base part 356 for the adjustment screw B to pass through vertically, and the side bracket 11 will also correspondingly There is a protrusion D protruding outward and located below the adjustment screw B. The user can rotate the adjustment screw B to move it up and down, and adjust the inclination angle of the mounting seat 351 relative to the seat 12 after pushing against the protrusion D, and then adjust the size of the aforementioned gap.

Referring to FIG. 2 , FIG. 3 , and FIG. 8 , the counting unit 4 includes a counter 42 that is recessed from top to bottom to form a sensing slot 41 , and a trigger 43 pivotally arranged in the installation space 181 and corresponding to the sensing slot 41 .

The trigger piece 43 is pivotally mounted on the corresponding side bracket 11 (in this embodiment, the side bracket 11 with the gear set 22 ), and a torsion spring 44 is arranged beside the trigger piece 43 , so that the trigger piece 43 is driven upward and partially protrudes from the seat 12 . When the part protruding from the seat 12 is pushed forward by the card, the trigger member 43 swings downward against the torsion spring 44 and is placed in the sensing slot 41.

Referring to Fig. 2, Fig. 3, and Fig. 9, the control unit 5 includes an integrated electric control module 51 placed in the housing 341, a plurality of electrical connecting wires (not shown) electrically connected to the electric control module 51, an inductor 53 forming a light-shielding groove 52 and electrically connecting the electric connecting wires, and a pressure-sensitive member 54 pivotally arranged in the installation space 181 and corresponding to the light-shielding groove 52. The lower end of the pressure-sensing element 54 is provided with a counterweight, so that the lower end of the pressure-sensing element 54 is inertially placed in the light-shielding groove 52 , and the upper end of the pressure-sensing element 54 protrudes from the seat 12 . The electrical connecting wires bypass the connecting rods 17 from below to electrically connect the motor 21, the electromagnetic coil 345, and the counter 42. Since the connecting rods 17 are located below the roller 33, the electrical connecting wires can be separated from moving parts such as the roller 33.

Referring to Fig. 1, Fig. 2, and Fig. 3, the mode of operation of this embodiment will be described below. First, a plurality of cards (not shown) are stacked up and down and put into the card space 182, and a pressure plate E is pressed on the cards. At this time, the pressure-sensitive member 54 will be pressed down, so that the pressure-sensitive member 54 leaves the light-shielding groove 52, and then power is supplied to the electronic control module 51 to drive the motor 21 to rotate. The motor 21 will drive the driven gear 23 and the driven gear 23 through the gear set 22. The driving pulley 24 rotates, thereby driving the rotating shaft 31 and the supply wheel 353 to rotate. The driving pulley 24 also drives the driven pulley 25 to rotate through the transmission belt 26 , thereby driving the supply roller 352 to rotate. Referring to Fig. 1, Fig. 3, and Fig. 6, the electromagnetic coil 345 is also energized so that the roller 33 is driven to rotate by the rotating shaft 31. When the protrusion 332 of the roller 33 passes through the slot 121, it will push against the lowermost card in the card-setting space 182, and drive the card to move forward through friction, so that the card passes through the gap between the block portion 357 and the seat 12 (other cards will be blocked by the block portion 357). The rotating supply roller 352 and the supply wheel 353 are sandwiched by the upper and lower sides. The supply roller 352 and the supply wheel 353 will drive the card to continue forward. When the card is transported forward to push the trigger 43, the trigger 43 will swing downward and be placed in the induction slot 41, so that the electromagnetic coil 345 is no longer energized through the electronic control module 51. After losing the magnetic force, the spring 348 will push the roller 33 back to its original position and will no longer be supported by the rotating shaft 31 Drive (even if the roller 33 continues to rotate due to inertia, it will not be able to drive the card due to insufficient torque), so that the roller 33 stops rotating and no longer drives the next card. Weight plus the reset of the torsion spring 44 will cause the trigger 43 to leave the induction slot 41, to impel the electric control module 51 to control the motor 21 to stop running 21, complete the action of outputting cards, and decide whether to continue outputting the next card according to the instruction. It should be noted that slots are provided on both sides of the pressure plate E, so when all the cards are sent out, the pressure-sensitive member 54 will pass through the slots. At this time, the electronic control module 51 will sense that there is no card in the card storage space 182, and remind the user to replenish cards by sound or display message.

In summary, the present invention only has a short drive belt 26, and the rest of the power transmission is mainly gears, which are more durable than the pulley mechanism and are easy to maintain and replace. The clutch mechanism 34 responds quickly and can ensure that the number of cards output is correct. In addition, the mounting seat 351 and the supply roller 352 are easy to replace, and the inclination angle can be adjusted according to requirements, so as to correspond to cards of different thicknesses.

But what is described above is only an embodiment of the present invention, and should not limit the implementation scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope covered by the patent of the present invention.
