The present invention relates to an apparatus for winding audit paper of a cash register. In general, a cash register includes a receipt for a buyer and an auditor stored by a seller, so that the buyer can be cut off the receipt and receive a receipt, and the same receipt can be rolled up and stored in the audit sheet.

Therefore, the receipted paper does not need a separate winding device for the typed resin, but the winding paper needs a winding device for storing it. After printing the same item details on the receipt and the audit paper, the resin paper is drawn out and the audit paper is rolled up. Conventionally, pulleys and gears that transmit the rotational force of the motor have a complicated configuration to apply the force to rotate the winding shaft at all times, so that the monitor is not wound around the winding shaft by the tension force of the auditorium. There was a fear that the gears would be overwhelmed and the paper would be torn.

In view of the above, the present invention simplifies the parts and forms a poly on the opposite surface of the latch wheel, which is usually addressed to the audit axis, so that the belts are hooked to the pulleys of the rotating gears fixed on the rotating shafts so as to alternate with each other. By removing the wear and noise of each gear by rotating the take-up shaft gear 18 by the transmission force due to the audit axis, which will be described in detail by the accompanying drawings as follows.

The present invention is configured such that the gear 2 arranged on the motor shaft 1 rotates in engagement with the gear 3 formed on the shaft of the reduction gear 8 as shown in FIG. 1 and coaxially with the reduction gear 8. The integrally formed gear 12 is configured to rotate in engagement with the gear 6 of the letter drum 5 formed on the live shaft 4.

Then, as shown in FIG. 3, a pulley 9 is formed on the roller of the audit shaft 7 to wind the belt 10 and the latch wheel 11 on the opposite surface (opposite) of the audit shaft 7 of the poly 9. The belt 10 is wound around the rotational shaft 13 and rotates as a nut 14, 14 and washer 15 on the rotation shaft 13. It is configured to rotate in engagement with the take-up shaft gear (18) where the washer (19) is for fixing the pulley (9).

The latching wheel 11 and the fixed audit shaft 7 shown in FIG. 2 are fixed through the long hole 21 of the pull rate 20 and guide pins 23 to the tongue hole 22 of the plate 20. ) So that the plate 20 can move left and right around the guide pin 23, and the clutch 25 is installed on the fixing shaft 24 so that the plate 20 can be latched at the same time. ) Is configured to rotate and the spring 26 is tensioned when the latch wheel 11 is rotated, so that the cam 26 is disassembled about the rotation shaft 27.

Then, the lever 29, which is held on the shaft 28 on the plate 20, is excited by the solenoid 30, and the lock gear 31 rises about the central axis 31 as it rotates about the type drum 5. Gear 5 and lock gear 31 is configured to mesh.

In the figure, reference numeral 40 denotes an audit paper and 41 an audit paper guide. When described in comparison with the operation effect of the present invention configured as described above as follows.

In the conventional audit paper winding device, as shown in FIG. 4, the pulley 51 is installed on the motor shaft 1, and the pulley 51 and the pulley 52 are connected by the belt 53. The nut 54, 14 ', and leaf spring 58 are connected to the reduction pulley 55 in the belt 54 and are connected to the pivot shaft 13 through the first and second transmission gears 56 and 57. , The rotating gear 59 is installed in the order of washer 15 so that the rotating gear 59 is engaged between the winding shaft gear 8 and the secondary transmission gear 57. The solenoid driving unit installed on the left side is As in Figure 5 has the same configuration as the present invention.

Therefore, when the motor rotates, the motor shaft 1 is rotated so that the first and second transmission gears 56 rotate the rotational speed reduced by the reduction pulley 55 through the belt 54 from the pulley 52 as the belt 53. (57) is transmitted to the rotational gear 59, and the rotational gear 59 is applied to the direction of the arrow to always winding the thank-you paper 40 by rotating the take-up shaft gear (18).

And as shown in FIG. 4, when the motor shaft 1 rotates, the letter drum 5 is rotated at a constant speed in the reduction gear 8, and the audit paper 40 wound around the audit shaft 7 guides the audit paper. The audit paper 40 is fixed to the winding shaft gear 18 through the sphere 4 so that the rotation gear 59 moves the audit paper 40 in the direction of the arrow due to the tension of the audit paper 40. Even if the force is applied to the audit paper (40) is not wound on the audit axis (7) and the rotating gear 59 is idling while sliding on the rotation shaft (13).

That is, since the nut 14 is adjusted to be used so that the tension of the paper 40 is greater than the adhesion of the leaf spring 58, the rotation gear 59 between the washer 15 and the rotation shaft 13 is a winding shaft gear. It is engaged with (18) and slips on the rotational shaft to idle.

At this time, if you print the details of the goods with a keyboard (not shown) is printed on the thank-you paper 40 in the letterpress drum (5) in the desired type and when the line of printing is finished, apply power to the solenoid 30 of FIG. The gears 6 of the lock gear 3 and the type drum 5 when the lock gear 31 rises about the central axis 31 while the 29 is excited and rotated to the right about the axis 28. Since the fitting type drum 5 is rotated, the plate 20 moves to the oil side along the guide pin 23 by the length of the tongue hole 22.

Therefore, the clutch 25 fixed to the fixed shaft 24 on the plate 20 rotates the latch wheel 11, and the audit paper 7 rotates to unwind the audit paper 40 and the audit paper 40 When there is no tensile force, the rotary gear 59, which slides on the rotary shaft 13, rotates the take-up shaft gear 18 to wind the audit paper 40, and at the same time is drawn out to the resin.

When the latching wheel 11 is rotated, the spring 33 is tensioned and the cam 26 is released from the latch wheel 11 and the spring 33 is reduced when the power is not applied to the solenoid 30. ) Is engaged with the latch wheel 11 to prevent the latch wheel 11 from rotating, and the plate 20 is also reduced to its original position, and the audit paper 40 is fixed while the audit axis 7, which is the central axis of the latch wheel 11, is fixed. As described above, the rotating gear 59 is idle.

That is, the conventional winding paper winding device, as shown in FIG. 6, receives the rotational force of the motor through the belts 53, 54, the pulley 52, the deceleration pulley 55, and the like, and transmits gears 56 and 57. FIG. Through the application of the force to drive the winding shaft gear 18 at all times in the rotational gear (59) through not only there is a risk of tearing the audit paper 40, but also the nut 14 (14 '), Since the rotating gear 59 is swept by the leaf spring 58 and washer 15, the gears are always engaged and rotated even when the audit paper 40 is not wound. It was the cause of easy wear.

However, the present invention is integrated with the pulley 9 and the rotating gear 17 fixed with the washer 19 on the opposite surface of the latch wheel 11 fixed to the audit axis 7 as shown in FIGS. 1 and 3. As the pulley 16 is formed by crossing the belt 10 to be connected, the nut 14, 14 'and the washer 15 are fixed to the pivot shaft 13, and as in FIG. Even if the solenoid 30 and the plate 20 are driven, the latch wheel 11 is normally fixed while being engaged by the cam 26, so that the auditor axis 7 and the pulley 9 (3) have been addressed. Since the rotating gear 17 connected as the belt 10 does not rotate because it is fixed, the rotating gear 17 engaged with the take-up shaft 18 is not subjected to rotational force to be normalized, so that the gears are not exerted on the mechanism, and each gear is There is no effect that there is no fear of generating noise while rotating normally.

Also, as shown in FIGS. 2 and 5, the cam when the clutch 25 rotates the latch wheel 11 operates in the same manner as in the prior art when the solenoid 30 is driven and the audit paper 40 is wound after printing. (26) is released from the latch wheel (11) and the latch wheel (11) is rotated, so as shown in FIG. 3, the rotating shaft (7) and the fixed pulley (9) is rotated through the belt (16) Since the rotation force is applied to the pulley 16 of 17) and the rotation gear 17 rotates the combined winding shaft gear 18, the audit paper is wound around the winding shaft, and when power is not applied to the solenoid, the rotation gear is reduced as usual. (17) It will not be reunited.

Therefore, the present invention constitutes the pulley 9 larger than the pulley 16 so that the rotational force applied to the pulley 16 is greater than the rotational force applied to the pulley 9 through the belt 10 so that It is possible to give an accurate winding of the audit paper 40 by increasing the rotation force, and by connecting the belt 10 to be crossed, there is an effect that does not need to separately configure a rotating gear to change the direction.

As described above, the present invention can provide an accurate winding when winding the audit paper, and can provide an audit paper winding device of the cash register which eliminates noise and wear caused by the rotation of each gear that is not normally required. .
