Abstract

PURPOSE:To enable a slip fitted in easily to be set to a predetermined position without providing any special stoppers or the like, by a method wherein a slip is momentarily attracted in, and then it is discharged by an amount larger than the attracting-in amount. CONSTITUTION:When an operator inserts the slip along a side surface guide 9b, a controlling part 12 actuates a solenoid 7 in accordance with a detection signal from a sensor 3, and actuates a motor 13 for operating an attracting-in roller 1. As a result, a metallic connector 5 is inverted so that the slip 10 is caught by the roller 1 and an auxiliary roller 1a, and starts to be attracted in. The rotating amount of the motor 13 is measured by a counter 15, and when the slip 10 is attracted in by a predetermined amount, the controlling part 12 stops the operation of the solenoid, and operates a discharging roller 2 so that the slip 10 is discharged by an amount larger than the attracting-in amount. The slip 10 is discharged to a position where it is released from the roller 2, and is stopped at that position. Accordingly, the slip 10 is set to the predetermined position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positioning device for a slip printer, and more particularly to a device for automatically positioning and printing a slip inserted casually by an operator.

Electronic cash registers and POS terminal Sung slip printers usually use discontinuous numbers (slips), so all slips must be set in predetermined positions before printing begins. .

However, these slip printers are often used in store registers, sales floors, etc., where operators are busy and do not have time to set slips in the designated positions, and they are often left unattended due to misalignment. I often have to retry all the times.

Therefore, automatic positioning devices for slips have been used in the past, and typical examples thereof include an alignment mark type as shown in FIG. 1 and a stopper type (not shown).

In the alignment mark type, a mark is attached to set the slip in a fixed position.As shown in Fig. and mark 20 on the edge of the slip.
Insert it into the roller 22 until it matches the . However, this method does not significantly reduce the burden on the operator.

The stopper type protrudes a stopper such as a stop plate or a stop bar so that all the inserted slips are stopped at a fixed position, and then the stopper 7 is released when the slip is transferred in the forward or reverse direction. This requires a complicated mechanism, which results in extremely high costs for use in slip printers.

Furthermore, as another method, as shown in FIG. 2, 1 silk suction roller 1. Conventionally, a mechanism consisting of a set of discharge rollers 2.2a and a side guide 9bt-ON has not been used.

In Figure 2, the function of a pair of contacting and stopped rollers r stoppers is provided for positioning the slip. In this case, when the operator inserts a stiff slip with strong force, the contacting roller (2.2& in FIG. 2) rotates and no longer functions as a stopper, causing the slip 10 to penetrate and become misaligned. Further, even if the inserted slip 10 is not inserted to the point i where it finally comes into contact with the rollers 2, 2aK, it is considered to have been set when it has completely passed the sensor 5. Normally, in FIG. 2, the entire side of the slip 10 is set along the side guide 9b, and the entire missing or rear end of the slip 10 is set along the mark or guide 7.
After that, all operations on the keyboard etc. are performed to give an instruction to complete the slip setting and start printing. Therefore, in this case, it is necessary to position the slip 10 in two directions, ie, the left-right direction and the front-back direction, and furthermore, an operation is required to issue an instruction to complete the slip setting, making the process extremely complicated. .

The purpose of the present invention is to solve these conventional problems,
There is no need for manual alignment or operations to indicate completion of document setting, and there is no need for special mechanisms such as stoppers or high-precision sensors. To provide a positioning device for a slip printer that can set a slip printer in a predetermined position.
be.

How to use the slip printer of the present invention W? -The JL device has one set of opposed rollers for ejecting the inserted slip k, four people, and one set of opposite rollers in a fixed position, -1-, i? r!
It is characterized by having a sensor that detects the entire insertion of a slip, a counter that measures the entire feeding distance of the slip, and a control section 7 that controls each part of the slip.

Embodiments of the present invention will be described below with reference to the drawings.

2 and 3 are side views of a positioning device for a slip printer to which the present invention is applied, and the second diagram shows a control system of a positioning device for a slip printer shown in Embodiment 7 of the present invention. It is a block diagram.

The present invention can be realized only by changing the control system, and the conventional mechanism shown in FIG. 2 can be applied as is.

In FIG. 2, a suction roller 1 for sucking in slips and a discharge roller 2 for discharging slips are driven by a motor 13 (FIG. 4) and rotate in opposite directions as shown by arrows in FIG. The suction auxiliary roller la and the discharge auxiliary roller 2a, which are provided opposite to these two rollers 1 and 2, are configured to alternately move up and down like a seesaw around the entire center of the shaft 4 by means of a connecting fitting 5. An arm 6 is engaged with the shaft 4, and the other end of the arm 6 is moved in the direction of attracting the penetrating rod by the drive of a solenoid 7, while being moved in the direction of removing the penetrating rod by the tension of a spring 8 when the solenoid 7 is not activated. will be moved. A sensor 5 for detecting the insertion of the slip 10 is provided between the suction roller 1 and the discharge roller 2, and the kneading is performed simply by inserting the slip I.
It is sufficient that the accuracy is low enough to detect that O is inserted. The table 9 is provided with a square window 9a and a slip inclined guide 9b having a structure in which the side surface of the table is folded back and bent.
is arranged so that it is partially exposed from the corner window 9a. slip l
A printing pad 11 for printing on O is placed n+' if immediately before the suction roller l.

As shown in FIG. 4, a suction roller 1 and a discharge roller 2
The motor 13 that drives the is controlled by a motor control unit 1, and this motor control unit 14ff is provided with a counter 15 that measures the total intake and discharge distance of the slip 10 by the amount of rotation of the motor 13.

Sensor 3, solenoid F7, motor 13, motor control section 1
4 and the counter 15 are each controlled by the control unit 12.

When the operator inserts a slip, the control section 12 issues instructions to each section by executing a program. First, the number of slips is increased, and then the entire slip is ejected until the slip comes off the ejection roller and stops moving. By setting the Nk starting point (fixed position), the position of the slip in the front and back direction is fully automatically set.

FIG. 5 is an operation flowchart showing an embodiment of the present invention.

The operator issues slip 10Til)tl! Men guide 9b
When the slip 10 is inserted, the sensor 3 detects the insertion of the slip 10.
and transmits it to the control section 12. In the control unit 12, step 3
Since it is checked in step 1 whether or not the slip IO has been inserted, the process proceeds to step 32 based on the notification from sensor δ.
To operate the suction roller l, rotate Chi-Yu 3. That is, when the control unit 12 fully operates the solenoid 'r, the arm 6 is attracted toward the slide/id 7 side, and the connecting fitting 5 is rotated around the axis 4 and the entire center k [7], and is reversed as shown in FIG. , the entire slip IO is captured by the suction roller 1 and the suction auxiliary roller la. control? 'i! At S12, a signal is simultaneously sent to the motor control section 14 to operate the motor 13, thereby causing the suction roller 1 to rotate completely.

At step 33, the slip 10 is inhaled. Next, in step 34, it is checked whether a certain amount of slips 10 have been inhaled. The suction distance of the slip IO is measured by the counter 15, and the value is transmitted to the control unit 12. dry-evening 1
To measure distance by rotation of motor 1,
The rotation fFl is counted by completely attaching a magnet to the disk of the Boo 9- connected to the 3 and detecting it with a detector.

When the suction distance reaches a predetermined value, the control unit 12 proceeds to steps 3 and 5 and operates the discharge roller 2. That is, by stopping the operation of the solenoid 7, the arm 6 is completely returned to its original position by the tension of the switching member 8, and the entire slip 10 is captured by the discharge roller 2 and the discharge roller 2a. The discharge roller 2 rotates in the opposite direction to the suction roller 1, and as the discharge roller 2 rotates, the slip 10t is discharged in step 36. In step 37, it is checked whether a certain amount of slips 10 have been discharged.

That is, since the ejection distance is also measured by the counter 15, if the ejection distance is set to be larger than the above-mentioned suction distance,
The slip 10 will definitely come off the discharge roller 2.

Once removed from the discharge roller 2, the slip 10 cannot be fed any further, so it stops at that position.

In step 38, the motor 13 is stopped and the solenoid 7
By operating , the slip 10 is fixed between the suction roller] and the suction auxiliary roller 1a.

That is, if the slip 10 is ↑1 [the position out of the output roller 2 is completely in the normal position, the slip 10 is set in the normal position at this point.

Next, in step 39, the print head IIK prints the slip 10.
Printing is performed on F, and feeding operation is performed by suction roller IK as necessary.

FIG. 6 is a side view of a positioning device for a slip printer showing another embodiment of the present invention.

In FIG. 6, the suction roller 1 and discharge roller 2 in FIG. 2 are used together, and each of the four auxiliary rollers la.

The rollers 2a are all one, forming a pair of opposing rollers 24, 25, and can be rotated in any direction in the opposite direction.

When the insertion detection sensor 26 indicates that the slip 10 has been inserted, the control section 28 controls the motor, counter, drive mechanism, etc. to perform the positioning operation according to the present invention. In addition, in FIG. 0, the operator inserts the slip lO'ft:
When this is fully detected, the driving mechanism moves the opposing roller 24
．． ．． A special mechanism is required to move the document to the position of the full sensor 25, capture the entire slip, and suck it.

In addition, the clutch 7 can be used to control the rotation and stop of the motor, and an electromagnetic ratchet can be used instead of the motor.
It is also possible to use h. Note that if the rotation of the motor is constant, a timer can be used instead of a counter.

As explained above, according to the present invention, the longitudinal position of the slip is automatically set, eliminating the need for manual alignment, eliminating alignment errors, and pressing the button to complete slip setting. is also no longer necessary. Further, according to the present invention, the mechanism can be simplified because it can be realized by using ordinary suction rollers and discharge rollers as they are without providing a discriminative stopper or a high-precision sensor for positioning.
