DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for identifying a master storage and an ink storage container, a method for identifying a master storage and an ink storage container, a printing apparatus, a method for identifying a master storage, and a method for identifying a master storage and an ink storage container. And an ink container.

[0002]

2. Description of the Related Art Generally, a printing apparatus is used while supplying a master (plate) and ink as supplies. And
The printing apparatus body has detection means such as a sensor for detecting the end of a master roll (master storage item) formed by winding a master and a sensor for detecting the absence of ink in an ink storage container storing ink. If they indicate a supply end, the operator can continue to use it by setting a new supply.

[0003] There are several different types of master rolls for stencil type stencil printing machines depending on the size and the type of master. There have been proposed several methods and methods for preventing them from being confused and accidentally mounting a different master roll on a stencil printing machine. The simplest is (1) a method of setting a plurality of types by changing the inner diameter (d) of the paper core around which the master roll is wound. There is also a method of (2) providing a specific mark (identifying means) inside or outside a paper core and detecting the mark with a sensor. An example of this is disclosed in, for example, JP-A-5-290227.

On the other hand, the most suitable ink for printing has been developed according to the type of master, the difference in the required print image, the difference in the use environment, and the difference in various other conditions. It has been used in the right combination. The types of ink are variously set for each color of ink, each machine type, each country and region used, and each sales channel. Several methods and methods have been proposed for preventing the ink storage containers provided for each type of ink from being confused and preventing a wrong ink storage container from being mounted on a printing apparatus by mistake. ing. The simplest ones are:
(3) a concave portion is provided at a different position on a part of an outer surface of the ink container, and a receiving portion for setting the ink container has a convex portion which can be fitted to correspond to the concave portion; There is a method for preventing erroneous mounting of the ink container by fitting the concave portion and the convex portion. This example is disclosed, for example, in Japanese Patent Application Laid-Open No. 10-264357 proposed by the present applicant.

However, the above-mentioned methods (1) and (2) for identifying the master roll and the method (3) for identifying the ink container have the following problems. The method (1) for identifying the master roll is the easiest and simplest to understand since the inner diameter (d) of the paper core is changed, but it is very troublesome to change this by going back to the manufacturing process of the paper core. In addition, there is a problem that a master roll that is "large also serves as small" and has a large inner diameter (d) of the paper core can be mounted and set on a device adapted to a smaller master roll.

In (2), for example, JP-A-5-290
The method of providing a specific mark (identifying means) inside or outside of a paper core disclosed in Japanese Patent Publication No. 227 is also troublesome since it is necessary to go back to the manufacturing process of the paper core and make many kinds of these. is there. Although there is a method of printing on the paper core later, there is a problem that the printing device becomes special and expensive because the inner diameter of the paper core is very narrow.

In the method (3) for identifying the ink container,

Next, the operation of the stencil printing apparatus will be described below. First, when a user or an operator (hereinafter, referred to as “user”) turns on a power switch (not shown),
An operation panel (not shown) (see FIG. 6 showing a first embodiment described later) and a control device (not shown) provided in the stencil printing machine enter a startable state, and a state in which power can be supplied to each device / unit. Become. Before or after the operation of turning on the power switch, for example, when there is a shortage of the printing paper 38 to be used in the current printing on the paper feeding table 39 using the main body paper feeding unit 73, After appropriately replenishing and loading the printing paper 38 of the paper type to be used for printing on the paper feed tray 39, for example, pressing a paper feed tray elevating key (not shown), the uppermost surface of the print paper 38 loaded on the paper feed tray 39 is pressed. To the position where paper can be fed (paper feed position).

Before and after the above operation, the original 29 is placed on the contact glass of the original reading section 70 and the pressure plate 31 is closed, and then a start key (see FIG. 6) arranged on an operation panel (not shown) push. Then, the scanner unit 30
Operates to read the image of the original 29. The scanner unit 30 performs scanning while illuminating the surface of the document 29 with a fluorescent lamp (not shown), reflects light reflected on the surface of the document 29 by a mirror (not shown), and then passes the reflected light through a lens (not shown). The light is made incident on the image sensor, and the image of the document 29 is read. Then, the image signal photoelectrically converted by the image sensor is input to an A / D converter (not shown) of the main body frame 77. When it is desired to continuously read an image of a plurality of originals and make a plate, the originals are placed on an original receiving table (not shown) of the ADF unit 32, and the originals are automatically separated one by one and the original is placed on the contact glass. The image is read in a state where the scanner unit 30 is fixed at a fixed position while feeding the image to the scanner.

On the other hand, in parallel with the reading of the image of the original 29, the plate making section 71 performs thermal processing based on the digital image signal processed and sent out by the A / D conversion section and the plate making control section. A plurality of heating elements arranged linearly on the head 34 selectively generate heat, and the thermal head 3
4, the thermoplastic resin film portion of the master 1a pressed by the platen roller 33 is selectively melted and perforated. Then, the leading end of the perforated master plate 1a thus perforated and made as described above is conveyed in the direction of the arrow shown in FIG. It is transmitted to the expanded master clamper 36.

Next, the master clamper 36 is closed at a predetermined timing to clamp the leading end of the master 1a, and the printing drum 35 is rotated in the direction of the arrow in FIG. 1a is wound around the outer peripheral surface of the printing drum 35. And
When a controller (not shown) determines that the plate making is completed by driving a stepping motor (not shown) that rotates the platen roller 33 by a predetermined number of steps, the master 1a is cut into a predetermined length by the cutter 37, and this cutting is performed. The finished master 1a is wound around the outer peripheral surface of the printing drum 35.

After the master 1a, which has been made, is wound around the outer peripheral surface of the printing drum 35, the printing process is started. First,
When the paper feed roller 40 and the separation roller 40A of the main body paper feed unit 73 rotate, the uppermost printing paper 38 stacked on the paper feed table 39 is moved by the cooperation of the separation roller 40A and the separation pad. Registration rollers pair 4 separated by sheets
Sent to 1. Next, at a predetermined timing synchronized with the rotation of the printing drum 35 by the registration roller pair 41, the printing paper 38 is
Is sent. Then, the press roller 42 that has been separated from the outer peripheral surface of the printing drum 35 moves upward, and a master (not shown) wound around the outer peripheral surface of the printing drum 35 that rotates in the direction of the arrow in FIG. 2), the ink is transferred from the perforated portion of the master 1a to the surface of the printing paper 38 to form a printing image corresponding to the stencil image, and stencil printing is performed. At this time, the ink supply roller 43 shown in FIG. 5 also rotates in the same direction as the rotation direction of the printing drum 35, and supplies ink to the inner peripheral surface of the printing drum 35. Then, the printed paper 38a is peeled off from the outer peripheral surface of the printing drum 35 by the peeling claw, and is sucked by the suction fan constituting the paper discharge transporting device 48, and is wrapped around the rotating suction roller and rotated. The back side is suction-conveyed along the conveying belt,
9 sequentially.

After the end of the printing, the press roller 42 separates from the print drum 35 and returns to the initial position, and enters a printing standby state. After the printing is completed, the user sets the output tray 49.
The printed matter discharged above is appropriately visually checked to determine whether or not a normal printing operation may be performed. If it is OK, the number of prints is set using a ten-key (not shown) on an operation panel (not shown) (see FIG. 6). Then, when a print key (not shown) is pressed, the steps of paper feeding, printing and paper discharging are repeatedly performed for the set number of prints in the same steps as described above, and the entire stencil printing process is completed. .

When printing is completed and the image of the next document is to be printed, the newly mastered master is transferred to the printing drum 3.
Before being wound around the outer peripheral surface of the printing drum 5, the used master previously used is peeled off from the outer peripheral surface of the printing drum 35. At this time, the print drum 35 is rotated in the direction opposite to the direction of the arrow in FIG. 3, and the print drum 35 stops at the plate discharging position. At the same time, an opening / closing device for opening and closing the master clamper 36 is operated, and the master clamper 36 is expanded. The locking state of the moving means is released by the locking means, and the lower plate discharging roller 50 occupies the peeling position as shown by a two-dot chain line in FIG. 9, and the plate discharging motor is turned on. As a result, the lower plate discharging roller 50 is pressed against the outer peripheral surface of the printing drum 35 corresponding to the tip of the used master (not shown) locked by the master clamper 36 while rotating. The leading end of the used master is picked up from the outer peripheral surface of the printing drum 35 by the lower plate discharging roller 50 and peeled off. Immediately after this, the lower plate discharging roller 50 is returned to the original separated position again by the moving means as shown by the solid line in the figure, and is held rotatably together with the upper plate discharging roller 50. After the opening / closing device is operated again and the master clamper 36 is closed, the printing drum 3 is closed.
5 is rotated in the direction of the arrow in FIG. The used master that has been peeled off is conveyed while being peeled off from the outer peripheral surface of the printing drum 35 by a rotation and conveyance operation while being held between the nip portions of the plate discharge roller pair 50, and is discarded inside the plate discharge storage box 51. It will be.

When the same printing process as described above is performed, the ink in the ink reservoir 45 shown in FIG. 6 is consumed and gradually decreases, and the ink detecting needle stops contacting the ink in the ink reservoir 45. Accordingly, an ink-out signal is transmitted from the ink detection sensor 46 to the control device. Upon receiving the ink-out signal, the control device operates the ink pump drive motor 5 to drive the ink pump 47.
A command signal for turning on the motor 3 is transmitted to the ink pump drive motor 53. Accordingly, the ink pump drive motor 53 starts operating and rotates, so that the piston rod of the ink pump 47 reciprocates, that is, the ink pump 47 pumps, so that the ink in the ink storage container 110 is sucked and drawn. The ink is supplied through the ink supply pipe 47A, drops into the ink reservoir 45, and is supplied and supplied to the ink reservoir 45.

When the ink is supplied to the ink reservoir 45, the ink detecting needle comes into contact with the ink in the ink reservoir 45 again, and the capacitance detected by the ink detecting needle increases. The ink detection sensor 46 detects the presence of ink, and transmits an ink presence signal to the control device. The control device stops the operation of the ink pump drive motor 53 based on the ink presence signal from the ink detection sensor 46. In the printing process, the above-described ink supply operation and supply stop operation are sequentially repeated, and the ink supply operation is performed so as to keep the ink amount in the ink pool 45 substantially constant.

The first embodiment differs from the stencil printing machine shown in FIG.
As shown in FIG. 1, a master roll 1 and an ink storage container 10 each having a unique identification means and being detachable as described above are used as supplies instead of the master roll 1 and the ink storage. The main difference lies in having the detection means 25 commonly used for discriminating both types of the container 10 and having the operation panel 60 shown in FIG. A configuration in which the master roll 1 has a detection unit 25 added to the stencil printing apparatus shown in FIG.

The tag 3 has a first coil 4, a second coil 5, and a resonance circuit 6. Since the tag 3 is affixed to the inner surface of the paper core 2, the presence of the tag 3 is not easily recognized from an external appearance. By changing the capacity of the capacitor or the number of turns of each of the coils 4 and 5, the tag 3 is different in size and type of the master (such as the material of the master 1 a and the material of the master 1 a) in accordance with the model and destination. Several different types can be easily set as the type based on the thickness or the type based on the number of printings of the master 1a.

Is done. It is desirable to form the tags 3 and 11 in this manner in order to reduce the size and thickness of the tags 3 and 11 and to reduce the storage space, mass productivity, and manufacturing cost.

The method of attaching the tag 3 to the paper core 2 of the master roll 1 and attaching the tag 11 to the outer box of the ink container 10 are, for example, a method of attaching and fixing with a double-sided adhesive tape. Although it is preferable in terms of the number of mounting steps and the number of man-hours, it is also possible to bond and fix with an appropriate adhesive or the like, or to form the base material of each of the tags 3 and 11 with a heat-fusible resin and fix them by heat fusion.

When the size of the plate is reached, the end mark portion 57 made of a black band provided on the final portion of the master 1a wound around the paper core 2 is changed by the master roll end detection sensor 55 made of a light reflection type sensor. Upon detection, based on the master end detection signal output from the master roll end detection sensor 55, the control device 22 causes, for example, the liquid crystal display unit 64 to display a message indicating the master roll end.

Then, according to the master roll end information displayed on the liquid crystal display section 64, the user mounts and sets a new master roll 1 on the roll supporting section 2A. When a new master roll 1 is set,
, The control device 22 operates the switching circuit 18 at a specific timing to electrically connect the detection control unit 19 to the detection unit 7 for the master roll, and the tag attached to the paper core 2 of the master roll 1. 3 is to detect and identify whether it is sensitive to a specific frequency.

That is, the frequency of the predetermined voltage generated by the high frequency generator 20 is applied to the master excitation coil 8. The voltage of a predetermined frequency applied to the master excitation coil 8 causes a current of a predetermined frequency to flow through the resonance circuit 6 via the first coil 4 of the tag 3 and induces a voltage of a predetermined frequency. The voltage of the predetermined frequency induced in the resonance circuit 6 induces the voltage of the predetermined frequency in the second coil 5 of the tag 3, and the voltage of the predetermined frequency induced in the second coil 5 detects the master signal. A voltage having a predetermined frequency is induced in the coil 9. Whether or not the voltage of the predetermined frequency induced by the master detection coil 9 is the predetermined voltage is determined by the voltage determination unit 21 of the detection control unit 19 via the switching circuit 18. The determined voltage determination signal is input to the control device 22. Control device 2
2 judges whether or not the resonance circuit 6 of the tag 3 is appropriate based on the voltage judgment signal output from the voltage judgment unit 21, and finally judges and identifies the type of the master roll 1. It will be.

If the set new master roll 1 is not a proper product, the control unit 22 displays the fact on the liquid crystal display unit 64 on the operation panel 60 to notify the user. At this time, a specific content displayed on the liquid crystal display section 64 is, for example, "The type of master roll is different. Please set the correct master roll." If the set new master roll 1 is not a proper product, the control device 22 prohibits the operation of the thermal head drive circuit and makes the thermal head 34 inoperative. As a result, the use of a master roll 1 that is not a proper product can be prevented twice and reliably. When the set new master roll 1 is a proper product, the plate making operation is automatically performed without any trouble. At this time, it is of course possible to prevent the use of the master 1a of the master roll 1 which is not a proper product by using other notification means such as a buzzer.

On the other hand, the same operations as those in the printing step and the plate discharging step described with reference to FIG. 9 are performed, and the ink is consumed by the printing and the plate discharging, and the amount of ink in the ink pool 45 is reduced. Is turned off, that is, when the ink-out signal is output, the control device 22 operates the ink pump 47 by driving the ink-pump drive motor 53 on to supply the ink to the ink reservoir 45. I have. Here, for example, in the case where the ink detection sensor 46 is still turned on even though the ink pump 47 is operated 15 times, that is, the ink detection signal is not output, the control device 22
Determines that ink has run out in the ink container 10 based on the ink empty signal output from the ink detection sensor 46, and displays an indication to that effect on the liquid crystal display unit 64.
It is made to be.

The user mounts and sets a new ink container 10 on the ink container receiver 54 in accordance with the ink empty information displayed on the liquid crystal display 64. When a new ink container 10 is set,
In FIG. 1, the control device 22 operates the switching circuit 18 at a specific timing to electrically connect the detection control unit 19 to the ink storage container detection unit 15, and the tag 11 affixed to the ink storage container 10. Is sensitive to a specific frequency.

That is, the frequency of the predetermined voltage generated by the high frequency generator 20 is applied to the ink excitation coil 16. The voltage of a predetermined frequency applied to the ink excitation coil 16 causes a current of a predetermined frequency to flow through the resonance circuit 14 via the first coil 12 of the tag 11 and induces a voltage of a predetermined frequency. The voltage of the predetermined frequency induced in the resonance circuit 14 causes the second coil 1 of the tag 11
3, a voltage of a predetermined frequency is induced, and the second coil 1
A voltage of a predetermined frequency is induced in the ink detection coil 17 by the voltage of the predetermined frequency induced in 3. Whether or not the voltage of the predetermined frequency induced by the ink detection coil 17 is a predetermined voltage is determined by the voltage determination unit 21 of the detection control unit 19 via the switching circuit 18. The determined voltage determination signal is input to the control device 22. The control device 22 controls the resonance circuit 1 of the tag 11 based on the voltage determination signal output from the voltage determination unit 21.
4 is determined to be appropriate, and finally the type of the ink storage container 10 is determined and identified.

If the set new ink container 10 is not a proper one, the control unit 22 operates the operation panel 60.
This is displayed on the upper liquid crystal display unit 64 to notify the user. At this time, a specific content displayed on the liquid crystal display section 64 is, for example, "Ink type is different. Please set correct ink." If the set new ink container 10 is not a proper product, the control device 22 prohibits the operation of the ink pump driving motor 53 and makes the ink pump 47 inoperative. As a result, the use of the ink in the ink container 10 that is not a proper product can be prevented twice and reliably. When the set new ink storage container 10 is a proper product, the ink supply operation is automatically performed without any trouble. At this time, it is of course possible to prevent the use of the ink in the ink storage container 10 which is not a proper product by using other notification means such as a buzzer.

As described above, the control device 22 operates the switching circuit 18 at a specific timing, and
Is connected to the detection unit 7 for the master roll. In this way, at a necessary timing, it is detected and identified whether or not the tag 3 attached to the paper core 2 of the master roll 1 is sensitive to a specific frequency. Next, the control device 22 operates the switching circuit 18 at another timing to electrically connect the detection control unit 19 to the ink storage container detection unit 15. In this way, it is detected at a necessary timing whether or not the tag 11 attached to the ink storage container 10 is sensitive to a specific frequency. As described above, the switching circuit 18 is controlled by the control device 22, and the detection and identification of the ink storage container 10 and the detection and identification of the master roll 1 can be performed by one detection control unit 19 with the detection timing shifted.

In the case where the master exciting coil 8 of the master roll detecting section 7 is replaced by the oscillation antenna and the master detecting coil 9 is replaced by the detecting antenna,
The configuration and operation of the detection means 25 in the case where the oscillation antenna is used instead of the ink excitation coil 16 of the ink storage container detection unit 15 and the detection antenna is used instead of the ink detection coil 17 are used for the master roll. The “master exciting coil 8” of the detecting unit 7 is “the oscillation antenna”, the “master detecting coil 9” of the master roll detecting unit 7 is “the detecting antenna”, and the ink container detecting unit 15
"Ink excitation coil 16" is replaced with the "oscillation antenna"
The "ink detection coil 17" of the ink storage container detection unit 15 can be easily understood and implemented by replacing the respective components with the "detection antenna" described above. Is omitted.

From the above, it can be said that in the first embodiment, the following method for identifying the master storage item and the ink storage container according to claims 1 to 4 is used. First
The master storage device and the ink storage container having detection means for identifying the type of the master storage device and the ink storage container which are detachable from the printing device main body and provided with the identification means on the printing device main body side The identification method of the type of the master storage item (master roll 1) and the identification method of the type of the ink storage container 10 are the same method, and the detecting means 25 detects the master storage item (master roll 1). ) And the ink container 10. Secondly, the detecting means 25 shifts the time of identifying the type of the master storage item (master roll 1) and the time of identifying the type of the ink storage container in time to thereby determine the type of the master storage item (master roll 1). And the type of the ink container 10 were sequentially identified.

Third, the tag 3 as the means to be identified of the master roll 1 and the tag 11 as the means to be identified of the ink container 10 belong to the same type. In other words, the tag 3 and the tag 11 are configured to be detectable by the detection unit 7 for the master roll and the detection unit 15 for the ink storage container having the same configuration.

Fourth, the tags 3 and 11 of the same type as the means to be identified are provided with the resonance circuits 6 and 14, and the detecting means 25 uses the respective exciting coils provided on the main body frame 77 side. A voltage of a predetermined frequency is induced in each of the resonance circuits 6 and 14 by a voltage of a predetermined frequency applied to each of the oscillating antennas 8 and 16, and a voltage of a predetermined frequency is induced in each of the resonance circuits 6 and 14. As a result, a voltage of a predetermined frequency is induced in each of the detection coils 9, 17 or each of the detection antennas disposed on the main body frame 77 side, and the voltage induced in each of the detection coils 9, 17 or each of the detection antennas is converted into a voltage. By making a determination via the determination unit 21, the master storage item (master roll 1) and the ink storage container 10 are identified.

Therefore, according to the first embodiment, the method of identifying the type of the master roll 1 (master storage) and the method of identifying the type of the ink storage container 10 are the same, and the master roll 1 (master storage) is used.

Can be detected or detected in a non-contact manner even if the distance is several tens of millimeters away. Therefore, the resonance tag has an advantage that the structure is simple and mass production is easy, so that the cost is low. In addition, even if the tag is tens of mm away, it can be detected or detected in a non-contact manner. It is easy to make it invisible from the appearance.

The above-mentioned resonance tag method is judged to be the most suitable identification means from the viewpoints of the technology and economy in the field of the current printing apparatus, because of its simple structure, easy mass production, and low cost.
