Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a label feed control device in a label printing machine that prints data from a measuring section on a label attached to a mount and then issues the label.

An example of a conventional label feed 9 control device! Figures 11 to 4
This will be explained based on the diagram. First, predetermined large pregnancy labels (2) are pasted at equal pitches on a long mount (1).
Such a mount (1) is wound into a roll and set in the label supply 5 (3). Then, the mount (
1) passes through a printer (4) which serves as a printing device, a peeling plate (5) which serves as a peeling unit, and a feed roller (7) which serves as a feeding unit driven by a motor (6) to a mount winding unit (8). reach

A photoelectric detector (9) is provided on the front side of the printer (4), and a label presence/absence is provided at the tip of the peeling plate (5) to detect the presence or absence of the peeled label (2). A detector (2) is provided.

Therefore, the programming unit αυ, the printer (4), and the display and operation unit (6) are connected, and the 90PU C3 has a % board)C.
1◆ is connected, the label presence/absence detector - is connected to the 4 baud) C14 via the label presence/absence detection AMPoR, and the paper feed controller (2) is also connected, and the paper feed controller (2) is connected to the paper feed controller (2). is a label detection AM connected to the motor (6) and equipped with a variable resistor (b);
The detector (9) is connected via P (tl).

Therefore, when the label (2) does not exist, the label presence/absence detector (G) outputs an operation command, that is, the signal +f
When jA is output, the paper feed controller (2) generates a signal C (H level), drives the motor (6), and moves the backing paper (
Perform the sending of 1). At this time, signal C is % boat α◆
It is also given to the CPU (Ll), and performs the expansion side of the operation that should not be performed during paper feed 9.

As the mount (1) is transported, the label (2) is peeled off and protrudes, causing the output signal of the label presence/absence detector to go to L level. If the detector (9) detects the position as described later and generates the signal B on the condition that this signal is at the L level, the signal C at the paper feed controller Q will be at the L level. The motor (6) is stopped and the CPU
(The prohibition order in 13 is lifted.

Therefore, the detector (9) detects the mount (1) and the label (2).
), but as shown in Figure 2 (4), this transmittance is different from when only the mount (1) is used or when the mount (1) and label (2) are overlapped. There are three types when it passes through (on the printed part of the label (2)).

Specifically, signal B is generated at the position of only the mount (1), but this is only the position of the mount (1) and the position of the mount (1).
Since the difference in the amount of light between the label (2) and the label (2) overlap is detected, the following problem arises. That is, the label (
If 2) has a high light transmittance, the difference will be extremely small, which has the disadvantage that a device with extremely high detection accuracy will be required. In addition, as mentioned above, if there is a printed part such as the store name on the label (2), the transmittance of this part is low, so there is a large difference from the label (2) part, which may cause detection errors. . Furthermore, there is also the hassle of having to perform variable resistance adjustment to adjust the detection level every time the thickness of the mount (1) changes. Moreover, when the size of the label (2) changes, the detector (
9), but this detector (9) has to be repositioned.
) is also the operating reference for the printer (4), so printing must be performed multiple times to determine the optimal position, which also causes the problem that the label (2) is wasted.

9. Other problems include the points shown in Figures 5115 and 6. First, the label (2) shown in Figure 5 (al) is in a stationary state, and the label (2) printed on the edge of the peeling plate (5) at the blank position can be removed. When a printing command is given, the printer (4) first performs the printing operation, and as shown in Figure 5, the printer (4) feeds the label (2) by the pitch it is attached to (in reality, it prints two sheets). It is not printed on the eye label (2), and the one shown shows a state in which it can be printed (the same applies hereinafter). In addition, the label shown in Figure 5 (6) is the label (2
) is large, the relationship between printing and feeding is the same. However, when trying to change the printing position on the label (2) as shown in Figure 5 (dl),
Unless the edge of the peeling plate (5) is moved from position A to position B, the sent-out label (2) cannot be held. Therefore, the position of the peeling plate (5) must be made movable, but it is extremely difficult to provide such a structural adjustment mechanism.

Next, what is shown in Figure 6 is a case where there are two printers (4), a product name mark (4) and a data printer (44).
and are arranged at a predetermined pitch as shown in Figure 6 (-1), and two bells (2) are arranged according to the size of 2 bells (2) as shown in Figure 6 (South and Figure 6 tel). Line printing is done.

However, when the printing position is changed as shown in Fig. 6(d), the edge of the peeling plate (5) must be moved from the person to the position B in the same way as shown in Fig. 5. There is a problem.

Furthermore, the distance between the product name mark (4ri and the data printer) is fixed and cannot be adjusted, and even if you try to set this distance narrower, you will be subject to mechanical constraints and will be limited to less than a predetermined value. There is also the disadvantage that it cannot be done.

An embodiment of the present invention will be described based on FIGS. 7 to 16. Components that are the same as those described with reference to FIGS. 1 to 6 are designated by the same reference numerals, and description thereof will be omitted. This embodiment has a leading edge detection function that detects when the leading edge Q■ of the label (2) reaches the front part of the peeling plate (5) in the running path of the mount (1), and a leading edge detection function that detects the presence or absence of the label (2). A label detector 4 having a detection function is provided, and a large number of slits (H) are installed on the axis of the feeder 90 (7), which is connected by a motor (6) such as an inductor 1W motor and a belt 4.
A slit plate 4 having slits arranged on the circumference is attached, and a slit detector for detecting the slits (c) is provided facing the slit plate (c).

The label detector is connected to the % boat α◆ connected to the CPU (13) via the leading edge detection AMP (c), and the paper feed roller J to which the motor (6) is connected is also connected. This paper feeder, °Metroroller, is connected to a feed rate setting device, which allows multiple settings to be set arbitrarily on the keyboard. The slit detector (b) is connected via a detection AMP 62).

However, when the label (2) is not present in the label detector block, the signal B is at H level;
When the signal is generated from the CPU side when is at H level, the signal D() is generated from the paper feed controller 4, which operates the motor (6) to feed the backing paper (1) and to feed the paper. A signal is given to the CPU o3 as a prohibition signal for parts that should not be operated during the process. and,
When the motor (6) starts, the rotational speed of the slit plate (2) is low due to the inertia of each part, so the slit detection AMP
The pulse width of the output signal C is variable, but after its initial state, the pulse period becomes constant. Like this, the mount (
When label 1) is fed at a constant speed, label (2) is peeled off and protrudes beyond the release plate (5), and finally the front edge (2) of label (2)
) is detected by the label detector (2). At the same time as this detection, the output signal B from the leading edge detection AMP@ becomes L level. According to this signal B, the sheet feeding unit starts counting the signal C from the slit detector (2), and when the counted number reaches the number set in advance by the sheet feeding amount setting device, If the signal is not at the L level, the peaker (6) is stopped. Therefore, the label (2) is its leading edge (2)
is detected by the label detection III@, a certain amount is fed out, and then stopped. Therefore, the reference signal is the leading edge (
In the detection of 2), since the difference in transmittance is large and the label (2) is not transparent, it is not related to the printed portion (2) of the label (2), so extremely accurate detection is achieved.

In addition, as long as label (2) is not removed, signal B will continue to be at L level, so no signal will be generated and other parts will not operate, and label (2) will be issued twice. Not announced. Therefore, the label detector (1) has the function of a conventional label presence/absence detector.

Next, a more detailed explanation will be given based on FIG. 11. What is shown in FIG. 11 is only a concrete implementation of each part of the block shown in FIG. 99, and the basic operation is completely unchanged. First, the label detector consists of an LED Cla and a phototransistor.
) is the oscillator (to) which is also connected to the conversion circuit (b)
and are connected via a driver (to). Further, the phototransistor (to) is connected to the conversion circuit (b) via a waveform shaping circuit (b). The oscillation frequency of the oscillator (c) is approximately 3 KHz, and the IJD C12
emits pulsed light periodically, and the conversion circuit (b) converts the output of the pulsed phototransistor (to) into direct current H and L levels. That is, when label (2) does not exist, the output is at H level, and when label (2) exists, the output is at L level. The purpose of using pulsed light emission in this way is to prevent the effects of ambient light and to emit LEDs with thin pulses in a rounded shape that is far from the LED (b) and phototransistor (to).
This is to strengthen the light of (to) and increase reliability.

The conversion circuit (B) is connected to the - boat α and the OR gate (To), and this OR gate (To) is connected to the down counter (2), which is a main component of the quantitative feeding means. . This down counter has a feed position setting device.
is connected. Further, an inverter (1) is connected to the input side of the OR gate (to), and the output part Q of the % port a4 and the 7 lip-flop is connected to the input side of this inverter. This flip-flop μ~ is connected to the % port α and the down counter), respectively. First, the output of the flip-flop is connected to a motor (6) through a driver wheel.

On the other hand, the slit detector (b) provided on the slit plate (2) consists of an LED (i4) and a phototransistor, and these 7 phototransistors are connected to a waveform shaping circuit.
It is connected to a differentiation circuit which differentiates the leading and trailing edges of the pulse to generate pulses twice as many as the number of slits (C), and this differentiation circuit (C) is connected to the down counter (2). Further, the differential circuit is connected to an overrun detector (b) for overrun detection, and this overrun detector (b) is connected to the boat α◆.

Further, a changeover switch for switching the printing state from one stage to two stages is connected to the % boat α◆.

Therefore, when there is no label (2) in the label detector 4, or when the flip-flop is reset, the output of the OR gate diagram is at H level and is sent to the down counter of the position setting device 2. Load content. Of course, no matter what state the contents of the down counter (2) are, it is loaded when the output of the OR gate (to) becomes H level, so it can also be considered as a preset. % in this state
When the feed signal is output from the boat Q4, the flip-flop (6) is set and the output of the inverter is set to L level, and the driver (6) outputs 9AC100.
Apply V to the motor (6). This allows the motor (6)
rotates to feed the mount (1), and at the same time the slit plate (2) rotates, generating a pulse from the phototransistor (product), and this pulse is given to the down counter (2) as a clock signal. . however,
Since the output from the conversion circuit (b) is still at H level, the contents of the down counter (2) remain unchanged.

While this state continues, when the leading edge (c) of the label (2) is detected by the label detector, the output from the conversion circuit (b) becomes L level, and the down counter is loaded. will be canceled. From this point on, when a pulse from the slit detection @@ side is input, the contents of the down counter will be subtracted,
When it reaches zero, the flippf tsubusuke is reset. This causes the motor (6) to stop and the down counter to be loaded again.

In this way, after the leading edge Q1 of the label (2) is detected, the label (2) is fed by a certain amount and then the feeding of the mount (1) is stopped.

However, even after the overflow detector (7-6) has stopped, the mount (1) will overrun, and if some other operation is performed during this overrun, there is a risk of malfunction. After the detector (6) has stopped, a signal is given to the CPIJ 01 at a fixed time interval.The physical circuit of this overrun detector is as shown in FIG. 12 or 13.

First, in the one shown in Figure 12, a transistor ring is connected to the differential circuit through an inverter, the emitter of this transistor is connected to the power supply, and the collector is connected to the resistance wheel through the shaft and capacitor. A comparator trout is connected. A divided voltage of the power supply ■ by the resistor fII) is applied to this comparator.
Its output is connected to the previous boat. Therefore, when there is an output pulse from the differentiator, the transistor conducts, charging the capacitor and maintaining the voltage across the comparator constant. When the pulse from the differentiating circuit disappears, the transistor is turned off and the charge in the capacitor is discharged, so that the output of the comparator becomes an L label and a signal indicating that the rotation has stopped is output. Even if the rotational speed slows down during overrun, the capacitor is charged when a pulse is received, so overrun monitoring can be performed reliably.

Next, the one shown in Figure 13 uses a monostable multivibrator whose time has been set in advance.
The monostable multivibrator is reset every time a pulse occurs, and when no pulse is generated within a certain period of time, the output of the monostable multivibrator goes to L level and gives a stop signal.

The above operation is such that the label detector detects the leading edge G of label (2)! After detecting the amount of paper, a fixed amount of paper is fed and the paper is stopped in a state where it can be taken out.In addition to this type of paper feed amount control, the amount of paper that is fed for printing is also controlled. This is set and controlled as a separate series, and specifically, several types of signals are set in the feed position setting device (2) by classification.

The state of printing on the label (2) will now be explained with reference to FIGS. 14 to 16. First, Figure 14 (-1~(
4) uses two printers (4) to print on the label, and there are two sizes of labels (2). First, Figure 14 shows the relationship between a stationary label (2), a printer (4), and a release plate (5).
Let the arrangement pitch of labels (2) be Ll, and the leading edge e when stopped
Let A be the distance between υ and the label detector (b). and,
When there is a label issue command, the label (2) remains in the stopped state.
Printing is performed on the image, and the feed 9 is performed. Is this done at the leading edge in Figure 14 (in the peak condition, and on the label detector)? After detecting hair, it sends only (LI A) and then stops. This condition also applies to labels (2) of different sizes as shown in FIG. 14 (ct).

Next, in Fig. 14 (Ol shows the printer (4)
In the case that the position and the printing position on the 7th bell (2) are different by X, 69, when a label issue command is issued, the label (2) is first fed by X and stops, and then returns to that position. is printed, and then sent again by (Ll-Xt).

However, the exact position at which the bell (2) stops is determined from when the label detector detects the leading edge 9I.
L + A) is due to #)'1k, and the transport 9
Even if printing is not performed continuously and the printing is stopped midway due to printing, the printing will be stopped under correct control as a whole. This state is carried out in exactly the same way even if the size of the label (2) changes as shown in FIG. 14 (number).

Next, based on FIG. 15, a case will be described in which there are two types of printing items, D and U, by one printer (4). First, what is shown in Fig. 15 (1) is the case where the arrangement pitch of labels (2) is Ll and the distance from the leading edge e1 to the label detector @ when stopped is A, as in Fig. 14 (-1). 15 (41), when there is a label issue command, the printer (
4) to print the printing items, and then
After sending os, print item U,
In addition, the label detector) is the leading edge G! After detecting υ, (LIA) is fed 9 and stopped.

Next, in the case shown in FIG. 15 (dl), after receiving a label issue command, the print item is printed by performing X feed, and then from the initial position by Xtt feed, and then printing U is printed, the label detector detects the leading edge of the label, and then stops at the position of (Ll-A).

However, in the case of ``C1 Fig. 15 (+1 (dl),
Feed amount xol, X, , x2. The setting is free. Therefore, the items to be printed on the surface of the label (2), the position of U, the distance between the two, etc. are determined according to specifications.

Next, what is shown in FIG. 15 (-1) is the feeding state when only one print item is printed even if there are two print items and the print program U is set. That is,
When there is a label issue command, the label is fed by XIO, then the printing items are printed, and then the printer (
4) is such that even when the program for printing the print item U starts to be executed, the label (2) is not allowed to stop a second time and is sent to the final position. Therefore, it is possible to increase the printing speed of the label (2).

Next, the printing state by the two printers (4) will be explained based on Fig. m16. That is, the printer (4
) Product name stamp (4b) Printer that prints numbers (4b)
). First, Fig. 16 (exploration) shows the arrangement of two types of printers (4) and the labels (2) arranged at a pitch of L, and the distance between the leading edge (■ and the label detector) is B. Indicates the condition.

However, in the case shown in Fig. 16 (4), when there is a label issue command, the product name stamp (44) and the printer (44) operate simultaneously at position 11, and after printing two items, In this case, the label detector (2) detects the leading edge (c), and then the label is fed at a pitch of L.
LB) and then stops.

Next, in the case shown in Fig. 1i16 (6), when a label issue command is issued, first the printer (4) operates to print data, then it sends a letter ``i'', then ``Xl'', and then prints the product name. (Printing is performed in a continuous manner, and then the label (2) is fed to a fixed position.

The rounded and printed line spacing is narrower than the spacing between the four product name stamps and the printer (44).
As shown in Figure (d), after the label issuance command is issued,
The printer (44) performs the X8 feed and prints the product name (44), and then performs the X8 feed to print the product name (44). ).Therefore, the structural arrangement of the product name mark (44) and the printer (44) should be set so that there is sufficient room for rounding up their maintenance and inspection. In addition, the print position can be appropriately determined by setting the feed amount and the operation timing of the printer (4).

Next, a second embodiment of the present invention will be described based on FIGS. 17 to 21. First, as mentioned above, the device has labels (2) arranged at equal pitches, a label detector (2) that detects the leading edge Qυ, and stops at a fixed position relative to the peeling plate (5). is set to. The printer (4) consists of two types of printers: four Jlil printers and a second printer (44).

These are mechanically attached and cannot be moved. Therefore, the first printing device #S (is for data printing and can be printed within the range α on the surface of the label (2), and the second printing device (4 is the product name stamp). It is possible to print within the range β.

However, a pulse motor is used as the drive unit,
It is connected to FEEDX10r4 which is connected to CPU (2). A waveform shaping circuit to which a label detector 4 is connected is connected to this FEED 510@. That's it,
The CPU o4 is connected to a ROM@, a RAM wheel, a keyboard controller wheel, and a printer controller, the keyboard controller is connected to a numeric keypad wheel, and a function key-1 display (turn), and the printer controller is connected to a printer controller. (4) That is, the first printing device (44) and the second printing device (44) are connected.

Next, what is shown in FIG. 19 is a RAM map, which has print positions 1-5. print position l
- 3 is for the first printing device (4), and its printing position is specified and corresponds to print data 1 to 3. Printing position 4 is for the second printing device (44), which is the product name stamp, and its printing position is specified. The print position is specified, and the corresponding print data 4 has no content.The print position 5 is used to set the feed amount after the label detector 4 detects the leading edge, and is a type of feed length. There are also feed length counters and label feed counters.
When the print key is pressed and a label issue command is issued, the bell feed counter is incremented by 1 every time the pulse motor @ rotates one pitch, and compared with each print position RAM, it prints out the data that is the same and corresponds to it. It is something. The conveyor flag is an auxiliary flag for comparing the contents of the print position RAM and the two-bell feed counter.

Therefore, the routine is @70- in Figure 20 and Figure 21.
This is done as shown in the chart. First, the manner mK of setting the feed die will be explained. After the start, if the print key is not pressed after the scale etc. are processed, the feed amount setting state is entered, the weight display is turned off, and 1 is displayed in the unit price field on the display section. Then, the print position RAM corresponding to the unit price column display area is displayed in the price column. Then, it is in a standby state for key-in, and each time a key-in is performed, the contents of the entered number are displayed in the price column, and when the execution key is pressed, the contents displayed in the price column are transferred to the print position RAM corresponding to the display of the unit price column, Check whether the unit price display is 5.

Right now, I have only set it up once, so click + to display the unit price field.
1 and return to position ■. In this way, the unit price display is 5
When the content has been set, it means that the feed amount setting has been completed and the process returns to step (3).

Next, when the print key is pressed to issue a label issue command, the routine shown in FIG. 21 is started. That is, the contents of the print position RAM 5 are transferred to the feed length counter, the label feed force and counter are cleared, the conveyor flag is set, and the contents of the print position specified by the conveyor flag are compared with the label feed counter, and if they match. Check whether it was done or not. If they do not match, check whether the conveyor flag is 4. Otherwise, add 1 to the d% conveyor flag and check the match again. If they match in this way, the specified pudding F data RA on the conveyor 72
The contents of M are sent to the printer controller 594, and the printer (4) is driven to print data or product name.

When the conveyor flag reaches 4, the label feed counter is increased by 1, the pulse motor is rotated by 1 pitch, and the leading edge is detected by the label detector (2). Drive the pulse motor until υ is detected. and.

When the label detector) detects the leading edge of the label (2), the feed length counter to which the contents of the print position IIIYAMs are transferred is decremented by 1, and the feed length counter is sent one pulse at a time until it becomes zero, and the process returns to (2).

As described above, the present invention detects the leading edge of two bells and then controls the label stop position setting to feed the label by a certain amount and then stop the label, as well as to detect that the label detector is not detecting the label based on the label issuing command. Feed the label to the printing position according to the conditions9.
As a result, we have provided a metered feed means that performs two types of control, one for controlling the printing operation, and the other for controlling the printing operation, so printing can be performed at any position on the label surface. By setting the and printing timing, you can easily set not only the printing position but also the line spacing and the order of printing columns. Even if it is set, any printing state can be obtained, and if the use of any printing device is prohibited, the paper feed 9 can be stopped during the operating time of that printing device. This is to allow high-speed issuance.
