  Since the conventional apparatus disclosed in Patent Document 1 is cleaned only by the pre-brush (3) with an ejector and the main brush (4) with an ejector, most of the ink attached to the wiping roller (1) is provided with the ejector. Washing with the pre-brush (3) and then washing with the main brush (4) with the spraying device, but the wiping roller (1) and the pre-brush (3) with the spraying device perform cleaning while in contact with each other. It does not reach the main brush (4) with an injection device. As a result, there is a possibility that ink that cannot be cleaned by the pre-brush (3) with the ejecting device or ink residue may be sent to the main brush (4) with the ejecting device.

  Also, normally, ink residue and precipitates remain in the piping through which the wiping solution is circulated. If this is used for many years, the piping may become clogged, resulting in poor circulation of the wiping solution. May cause paper generation and damage to the rollers.

  As a result, intervention of an operator is indispensable for cleaning the wiping device, and a considerable amount of time is required. Furthermore, the work of removing heavy wiping rollers is not only dangerous, but also causes the situation that the roller surface is damaged when the wiping rollers are removed and installed, and the rollers must be replaced. was there.

  The device disclosed in Patent Document 2 is a device that automatically puts and removes the wiping tank from the printing machine main body, but does not perform automatic cleaning in the wiping tank after completion of printing, and starts printing from the end of printing. About the wiping cleaning work up to that time, there still remains a problem of achieving automation.

  The present invention aims to solve the above-described problems. Specifically, in the wiping device in an intaglio printing machine, an irradiating device for cleaning the wiping roller and the wiping tank is provided. It is an object of the present invention to provide an automatic cleaning device and an automatic cleaning method for automatically performing wiping cleaning work while the wiping device is set in a printing machine by spraying cleaning water from an injection device installed in the printer. Is.

  The automatic wiping cleaning device of the present invention includes a wiping roller for wiping off excess ink on the intaglio plate surface and a wiping solution or cleaning water sprayed on the lower front side of the wiping roller and in contact with the wiping roller. A pre-brush with a device, a main brush with a spray device which is located on the lower rear side of the wiping roller and sprays the wiping solution or cleaning water while being in contact with the wiping roller; and a solvent or cleaning water sprayed on the wiping roller. In the wiping apparatus having a finishing blade scraped off while being in contact with the wiping roller, an intermediate injection apparatus that is located between the pre-brush with the injection apparatus and the main brush with the injection apparatus and injects cleaning water without contacting the wiping roller And at the bottom of the wiping tank A wiping tank lower cleaning device, which is provided at the corner of the wiping tank and cleans excess ink deposited in the wiping tank, and a cleaning water supply tank for supplying cleaning liquid to the brushes, the intermediate spray device, and the wiping tank lower cleaning device are connected to each other. The inside of the wiping tank is automatically cleaned by the cleaning liquid sent from the cleaning water supply tank.

  In the automatic wiping cleaning method of the present invention, upon receiving a signal to start cleaning of the wiping device, the solution supply electromagnetic valves are closed at the same time, and at the same time, the cleaning water flow switching valve is opened. Wash water is supplied from the supply tank to the laminar flow device installed in the wiping tank, the pre-brush with the injection device, the main brush with the injection device, the intermediate injection device, and the lower cleaning injection device of the wiping tank through the cleaning water feed pipe. The pre-brush with the injection device and the main brush with the injection device are ejected from the pre-brush with the injection device and the main brush with the injection device without bringing the pre-brush with the injection device and the main brush with the injection device into contact with the wiping roller. The pre-brush with the spraying device and the The surface of the wiping roller is cleaned by wiping the surface of the wiping roller by bringing the cleaning brush into contact with the rotating wiping roller and spraying laminating water from the laminar flow device, pre-brush with spray device, main brush with spray device and intermediate spray device The cleaning water adhering to the roller surface is scraped off by a finishing blade, and the cleaning water is sprayed from the lower cleaning jetting device of the wiping tank to remove the ink accumulated in the lower part of the wiping tank. It is characterized by automatically transferring waste liquid to the outside.

  In the automatic wiping cleaning method of the present invention, the wiping tank, the wiping roller, the pre-brush with the spraying device, the main brush with the spraying device, and the cleaning of each solution pipe are performed with the wiping bath fixed to the printing machine by the automatic wiping cleaning device. It is a method performed simultaneously.

  By installing the intermediate spraying device between the pre-brush with the spraying device and the main brush with the spraying device, the cleaning water is sent to the main brush with the spraying device, and excess ink and ink residue are removed from the main brush with the spraying device. The life of the main brush with the injection device can be extended.

  Automatic cleaning of the inside of the wiping tank is possible at the same time as cleaning each part of the printing machine, so there is no need to stop the machine to move the wiping device, cleaning work, and wiping device installation work, saving labor and improving work safety Work time can be shortened and productivity can be improved.

  Also, after printing, cleaning water is sent to each pipe where the solvent was circulated during printing to remove ink residue deposited on the inner wall of the pipe, and the cleaning liquid is discharged without being circulated. It is also possible to perform cleaning inside. In addition, since a good quality wiping solution can be supplied at all times during printing by cleaning the inside of the pipe, an effect of preventing clogging of the injection port can be obtained, and printing with stable quality can be performed.

  Furthermore, since there is no manual intervention such as removing and cleaning the wiping roller, wiping tank, cleaning member and finish cleaning member, the removal work is eliminated, so there is no damage to the roller when it is reinstalled, and time is wasted. This has the effect of reducing the cost of the material.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of the inside of a wiping tank of a wiping apparatus according to the present invention. FIG. 2 shows a wiping piping system diagram of the wiping apparatus according to the present invention. FIG. 3 shows a flowchart of the automatic cleaning operation of the wiping apparatus of the present invention.

First, the configuration of the automatic wiping cleaning device will be described with reference to FIG. In the wiping tank (10) in which the wiping device is integrally formed, a wiping solvent is poured over the wiping roller (1) by the laminar flow device (2). The wiping roller (1) is rotatably supported by the wiping tank (10), and rotates in the opposite direction by contacting the intaglio plate mounted on the intaglio plate cylinder (18) in the circumferential direction. .

  Two sets of lever mechanisms (30a, 30b) are respectively attached to the inner surfaces of the left and right side walls of the wiping tank (10), and one lever mechanism (30a) supports a pre-brush (3) with an injection device, and The main brush (4) with an injection device is supported by the other lever mechanism (30b). Further, an intermediate injection device support member (43) is provided between the devices, and the intermediate injection device (5) is supported by the support member.

  Between the left and right brush arms (31a, 31b) in the two sets of lever mechanisms (30a, 30b), brush support shafts (32a, 32b) that are slightly longer than the wiping roller (1) are rotatable and adjustable (33a) 33b) is pivotally supported so as to be positioned and fixed at a predetermined inclination angle. Moreover, although the intermediate | middle injection apparatus (5) is fixed to a support member (43), it has a function which can change an angle.

  Frame-shaped brush holders (34a, 34b) as unit holders are respectively fixed to the brush receiving shafts (32a, 32b), and stainless meshes are stretched on these brush holders (34a, 34b). A brush device having a brush mounted thereon is supported, and an intermediate spray device (5) is supported by a support member (43) in the middle of the device, and the pre-brush (3) with spray device as a cleaning unit body and the spray device An attached main brush (4) and an intermediate injection device (5) are formed.

  The intermediate injection device (5) is installed between the pre-brush (3) with the injection device and the main brush (4) with the injection device, and is provided below the wiping tank (10) or on the side surface of the wiping tank (10). It is fixed by a support member (43). The intermediate spray device (5) is provided with spray ports arranged in a zigzag at regular intervals in the upper portion so as not to contact the wiping roller (1), and sprays cleaning water from the spray port to the wiping roller (1). It is a mechanism.

  When cleaning is performed only with the pre-brush (3) with a spraying device and the main brush (4) with a spraying device provided in the conventional device, most of the ink attached to the wiping roller (1) is pre-brush with the spraying device (3). After that, the main brush (4) with the spray device is cleaned, but the wiping roller (1) and the pre-brush (3) with the spray device perform cleaning while being in contact with each other. ) As a result, there is a possibility that ink that cannot be cleaned by the pre-brush (3) with the ejecting device or ink residue may be sent to the main brush (4) with the ejecting device. The intermediate spray device (5) is installed between the pre-brush (3) with the spray device and the main brush (4) with the spray device, thereby sending the cleaning water to the main brush (4) with the spray device. Ink or ink residue is prevented from being sent to the main brush (4) with a jetting device.

  Further, the wiping tank lower cleaning / injection device (6) is installed and fixed on the bottom surface of the front lower portion of the wiping tank (10), and is periodically provided from an injection hole or a long hole arranged on one side of the wiping tank lower cleaning / injection device (6). The washing water is sprayed onto the ink and the ink scraped off by the pre-brush (3) with the spraying device and the main brush with the spraying device is accumulated on the bottom surface of the wiping tank (10).

  Although the bottom surface of the wiping tank (10) is inclined to reduce ink accumulation, it is impossible to eliminate ink accumulation on the bottom surface, and the conventional cleaning operation is performed after printing is finished and the machine is stopped. The roller was removed and the ink deposited on the bottom surface was removed manually. Therefore, the lower wiping tank cleaning and ejecting device (6) automatically removes the ink accumulated in the wiping tank (10) by ejecting the cleaning water onto the bottom surface of the wiping tank (10), and automatically removes the ink accumulated in the wiping tank (10). It can be washed.

  Further, the cleaning water feed pipe (39) and the cleaning water feed pump (37) are used to connect the cleaning water supply tank provided outside the wiping tank (10) and the wiping tank (10).

  Next, circulation of the wiping solution or the washing water will be described according to the wiping piping system diagram of the wiping apparatus shown in FIG.

  During printing, the washing water flow switching valves (16, 17) for feeding washing water from the washing water supply tank (12) to the wiping tank (10) are in a closed state, and the wiping solution circulation tank (11) The wiping solution supply electromagnetic valve group (13) and the wiping solution return valve (14) for feeding the wiping solution from the wiping tank (10) to the wiping tank (10) are in an open state.

  The wiping solution fed from the wiping solution circulation tank (11) through the solution circulation feed pipe by the wiping solution circulation feed pump (35) when the wiping solution supply electromagnetic valve group (13) is in the open state. The solution is sent to a laminar flow device (2), a pre-brush (3) with an injection device and a main brush (4) with an injection device in the wiping tank (10), and intaglio plate cylinder (18 ) The excess ink on the intaglio printing plate wound around is wiped off by the wiping roller (1), and the excess ink scraped off is accumulated in the lower part of the wiping tank (1). The wiping solution is circulated by returning to the wiping solution circulation layer (11) by the solution circulation return pump (36) and being sent again during printing.

  Excess ink deposited in the wiping tank (19) is discharged from the waste liquid port (8) by opening the waste liquid switching valve (15).

  After printing, the wiping solution supply electromagnetic valve group (13) for sending the wiping solution from the wiping solution circulation tank (11) to the wiping tank (10) is closed by a signal from a control device (not shown). Instead, the washing water flow switching valves (16, 17) for feeding the washing water from the washing water supply tank (12) to the wiping tank (10) are opened.

  When the wash water flow switching valve (16, 17) is opened, the wash water fed from the wash water supply tank (12) by the wash water feed pump (37) through the wash water feed pipe (39) is , Laminar flow device (2) in wiping tank (10), pre-brush with injection device (3), main brush with injection device (4), intermediate injection device (5) and wiping tank lower cleaning injection device (6) Washed away.

  Usually, ink residue and precipitates remain in the pipe circulating the solvent. If this is used for many years, it will cause clogging of the piping, resulting in poor circulation of the solvent, and may also cause the generation of broken paper and damage to the rollers. By sending cleaning water to the piping where the solvent was circulated during printing, and draining the cleaning liquid that passed through the piping without circulation, the ink residue and sediment in the piping It is possible to keep the inside of the pipe clean, and to prevent trouble of solvent circulation and generation of waste paper due to wiping. The waste liquid that has been washed with the washing water is discharged from the waste liquid port (8).

  Next, the cleaning procedure will be described according to the automatic cleaning operation flow shown in FIG.

  After the printing is completed, the cleaning start button on the wiping operation control panel (27) is set to “ON”, and automatic wiping roller cleaning starts (STEP 01).

  First, it is confirmed whether or not the wiping tank (10) is fixed to the machine (STEP02). Usually, it is in a fixed state during printing and at the end of printing. As a result of confirmation, if already fixed, the process proceeds to STEP 03, and if not fixed, the wiping tank is fixed, and the process proceeds to STEP 03.

  After confirming that the wiping tank (10) is fixed, it is confirmed that the wiping roller (1) is not in contact with the plate surface. At the same time, it is confirmed that the pre-brush (3) with an injection device and the main brush (4) with an injection device are not in contact with the wiping roller (1) (STEP 03). If they are not in contact and are in a detached state, the process proceeds to STEP 04. If not removed, the wiping roller (1) is brought into a non-contact state with the plate surface, and the pre-brush (3) with the spray device and the main brush (4) with the spray device are brought into a non-contact state with the wiping roller (1). Then proceed to STEP 04.

  The wiping roller attaching / detaching member (42), the cleaning member attaching / detaching members (25a, 25b), and the finish cleaning member attaching / detaching member (26) are interlocked. Normally, when the wiping roller (1) is detached from the printing plate, It is desirable that the pre-brush with the spray device (3), the main brush with the spray device (4), and the finish cleaning member (7) also have a mechanism for detaching from the wiping roller (1).

  After confirming that the wiping roller (1) is not in contact with the printing plate, the wiping roller (1) is rotated (STEP04), and the process proceeds to STEP08.

  Further, when the cleaning start button is “ON”, the wiping solution supply electromagnetic valve group (13) is closed at the same time, whereby the laminar flow device from the wiping solution circulation tank (11) through the solution circulation feed pipe (44). (2) The wiping solution sent to the pre-brush (3) with an injection device and the main brush (4) with an injection device stops all at once. At the same time, the flush water flow switching valves (16, 17) are opened (STEP 05).

  Next, in order to confirm that the circulating layer is cleaning water, it is confirmed whether or not the valve is switched (STEP06). If the valve is switched and it can be confirmed that the cleaning water is used, the process proceeds to STEP08. If the wiping solution is not the cleaning water, the valve is switched to the cleaning water flow and the process proceeds to STEP08.

  When the wash water flow switching valve (16, 17) is opened, the wash water fed from the wash water supply tank (12) by the wash water feed pump (37) through the wash water feed pipe (39) is , A laminar flow device (2) installed in the wiping tank (10), a pre-brush (3) with an injection device, a main brush (4) with an injection device, an intermediate injection device (5), and a wiping tank lower cleaning injection device ( 6) (STEP08).

  It is confirmed that the manual / automatic selection switch of the finishing cleaning member (7) on the wiping operation control panel (27) is selected to the interlocking mode (STEP09). If the interlock mode has been selected, the process proceeds to STEP 12. If the interlock mode has not been selected, the interlock mode is switched (STEP 10). The switching operation is confirmed again (STEP 11), and after confirming, the process proceeds to STEP 12.

  First, the pre-brush (3) with an injection device and the main brush (4) with an injection device that are not in contact with the wiping roller (1) are washed with the supplied cleaning water (STEP 12).

  After the pre-brush (3) with the spray device and the main brush (4) with the spray device are cleaned, the finish cleaning member (7) is attached to the wiping roller (1) (STEP 13), and the pre-brush (3) with the spray device And the main brush (4) with a spraying device is put on the wiping roller (1) (STEP 14).

  The pre-brush (3) with the jetting device and the main brush (4) with the jetting device that have been cleaned come into contact with the rotating wiping roller (1) to clean the surface of the wiping roller (1), and further, the lower wiping tank cleaning jet The ink deposited on the lower part of the wiping tank (10) is removed by washing with the apparatus (6) and washed.

  Cleaning is performed until the timer for automatic cleaning of the wiping device set in advance on the wiping operation control panel (27) ends (STEP 16), and when the timer ends, the process proceeds to STEP 17.

  After the timer setting time of the wiping device automatic cleaning ends, the pre-brush (3) with the injection device and the main brush (4) with the injection device are removed (STEP 17), and the flow and injection of the cleaning water are stopped (STEP 18).

  Next, the finish cleaning member (7) is removed (STEP 19), and the rotation of the wiping roller (1) is stopped (STEP 20).

  The washing water or warm water used for washing passes through the waste liquid circulation feed pipe (40) from the waste liquid port (8) by closing the wiping solution return valve (14) and automatically opening the waste liquid switching valve (15). Waste liquid.

  After completion of the cleaning, all the cleaning water supply valves are closed, and the wiping solution supply valve is closed and waits until a printing start signal is received (STEP 21).

  The wiping device automatic cleaning ends (STEP 22).

  In the best mode for carrying out the present invention, the intermediate spraying device (5) and the wiping tank lower cleaning spraying device (6) do not operate during printing, and are cleaned when the wiping device after printing is cleaned. Although described as a device for injecting water, it need not be limited to this.

  For example, the intermediate spray device (5) may be operated during printing to spray the wiping solution onto the wiping roller (1). In this case, first, the ink on the surface of the wiping roller (1) is dissolved by the wiping solution ejected from the laminar flow device (2), and most of the ink adhering to the wiping roller (1) is scraped with the pre-brush (3) with the ejector. Then, the surface of the wiping roller is finished by the main brush (4) with a spraying device.

  The laminar flow device (2) feeds the wiping solution along the outer periphery of the wiping roller, but the prebrush (3) with the ejecting device scrapes ink while contacting the wiping roller (1), so that the wiping solution is ejected by the ejecting device. It does not reach the main brush (4). As a result, there is a possibility that ink that cannot be scraped off by the pre-brush (3) with the ejecting device or ink residue accumulated on the pre-brush (3) with the ejecting device may be sent to the main brush (4) with the ejecting device.

  Therefore, by installing the intermediate spraying device (5) between the pre-brush (3) with the spraying device and the main brush (4) with the spraying device, the two inks that could not be scraped off by the pre-brush (3) with the spraying device. It is possible to promote the subsequent dissolution and to prevent excessive ink or ink residue from being sent to the main brush (4) with the ejecting device.

  Further, the wiping tank lower cleaning jetting device (6) may be operated during printing so that ink does not accumulate on the bottom surface of the wiping tank (10). In this case, the ink scraped off by the pre-brush (3) with an ejector and the main brush (4) with an ejector falls on the bottom surface of the wiping tank (10), and the ink scraped off on the bottom surface of the wiping tank (10). Before depositing, the cleaning water is ejected from the wiping tank lower cleaning spray device (6) to be discharged out of the wiping tank. As a result, there is no accumulation of ink on the bottom surface of the wiping tank (10), and the automatic cleaning operation after the printing can be performed efficiently.
