Description

  The present invention relates to a wiping device for an intaglio printing press, and more particularly to a wiping drive device.

  As shown in FIG. 1, the printing operation in a normal intaglio printing machine is performed by transferring ink to the intaglio plate surface on the intaglio cylinder (2) by the inking device of the intaglio inker (4), and the intaglio plate surface of the transferred ink. After wiping off the ink adhering to the portion other than the concave portion with a wiping roller, the ink in the concave portion of the remaining intaglio plate surface is transferred to the paper passing between the intaglio cylinder (2) and the intaglio impression cylinder (3). Printing. At this time, the wiping roller was pressed by manually moving the eccentric bearing on the intaglio plate surface, and the rotational force of the drive motor was fixed to one shaft end of the wiping roller (11) via the pinion gear. The gear is transmitted to the gear and comes into contact with the intaglio cylinder (2) so that the contact peripheral surfaces rotate in opposite directions.

  As a driving device for a wiping roller of an intaglio printing machine, a wiping device by the applicant of the present application has been proposed. In this wiping device, a wiping roller is suspended, an operation side bearing mounted on the left and right end shafts of the wiping roller, a mechanism for fixing the driving side bearing with an openable / closable metal cover, and an advancing and retracting direction by hydraulic pressure. Wiping roller support frame enabling free movement, guide rail for horizontally moving the wiping roller support frame against the intaglio plate cylinder, a bracket for connecting the wiping roller support frame and the wiping tank, and a bracket A metal net is attached to the base frame built in the holder that can follow the set pressure in the axial direction of the wiping roller as the wiping roller fluctuates. Has an opening on the top that does not prevent ink dropout and is flexible A plurality of cleaning members carrying synthetic fiber scrubbers, a pressure gauge that measures the reaction force in the horizontal direction from the intaglio cylinder, and a direct-acting screw that is pivotally attached to the servomotor, idle gear, and detachable hydraulic mechanism cylinder The pressure adjustment mechanism that changes the position of the wiping roller by the mechanism screw and nut, the pressure gauge that measures the reaction force of the wiping roller against the intaglio cylinder, and the pressure adjustment of the wiping roller against the intaglio cylinder at preset values The structure is provided with a control device that can be automatically performed (for example, see Patent Document 1).

  However, this driving device for transmitting the driving force of the wiping roller transmits the motive power generated by the prime mover to the wiping roller via the speed reducer, pinion gear, and wiping roller gear. In this method, when driving the wiping roller, torque in the rotational direction acts on the wiping roller gear by the driving-side pinion gear.

  As a result, a force is applied to the wiping roller gear to leave the intaglio cylinder. For this reason, the driving side bearing of the wiping roller receives a strong force in a direction away from it, and the operation side bearing receives an acting force in the opposite direction with the driving side bearing as a fulcrum. As a result, the left and right pressures are in an unbalanced state, causing the wiping roller to wear unevenly.

  Therefore, in order to solve the above-described problems and further improve workability, an improved wiping device has been proposed by the present applicant so that the pressure on the driving side and the operation side can be evenly performed. This wiping device has a mechanism for suspending the wiping device and fixing the bearing installed at the shaft end of the wiping roller with an openable / closable metal cover, and the wiping roller can be moved back and forth by oil pressure in the attaching / detaching direction. A wiping support frame composed of a finishing blade mechanism enabling movement, a guide rail for horizontally moving the wiping roller support frame with respect to the intaglio cylinder, and a wiping roller support frame and the wiping tank are joined together. Braking, pressing mechanism composed of a hydraulic cylinder part connected to the bracket, a hydraulic mechanism piston part and a hydraulic control part, and the axis of the wiping roller as the wiping roller wears and changes in diameter due to temperature changes Base frame built into a holder that can follow the set pressure in the direction A plurality of cleaning members on which a metallic net is stretched and an opening that does not hinder ink removal and on which a flexible synthetic fiber scrubber is placed, a wiping roller shaft and a wiping roller drive shaft are provided. It has a structure having a universal joint mechanism (coupling) for direct connection (see, for example, Patent Document 2).

  As shown in FIG. 2, the wiping drive device transmits the drive from the wiping drive motor (5) to the speed reducer (6), and transmits the drive from the speed reducer to the coupling (9) through the drive transmission shaft (7). The driving force is transmitted to the roller shaft (10) to rotate the wiping roller (11).

  The drive transmission shaft (7) and the machine frame (13a) of this apparatus are fixed by a drive transmission bearing (8), and thereby, a wiping roller disposed inside the machine for driving a motor installed outside the machine. Communicated.

  Further, by connecting the drive transmission shaft (7) and the drive-side wiping roller shaft (10) with a coupling (9), the drive transmission shaft (7) and the wiping roller shaft (10) can be prevented from being misaligned. Drive can be transmitted.

  The shape of the coupling is shown in FIG. The coupling is attached to the tip of the drive transmission shaft (7) on the wiping roller side via the drive transmission bearing (8), and the drive side hub (20) is attached to the two convex portions of the drive side hub (20). Two concave portions corresponding to the intermediate hub (21) are fitted, and further, the roller side hub (22) is inserted into two concave portions different from the concave portion into which the driving side hub (20) of the intermediate hub (21) is fitted. ) Is a mechanism in which the two convex portions to be slid are fitted.

  Further, the convex portion of the driving side hub (20) and the convex portion of the roller side hub (22) are arranged so as to be 90 degrees (cross).

  As shown in FIG. 4, the drive transmission shaft (7) and the coupling (9) arranged and formed as shown in FIG. 3 are fixed to the drive-side machine frame (13a) by the drive transmission bearing (8). Is done.

  If the wiping roller prints for a long time, its diameter will be reduced due to wear.If the wiping roller continues to be printed at the same position, the contact pressure between the intaglio plate and the wiping roller will be weak or a gap will be created. As a result, excess ink on the intaglio plate surface cannot be scraped off, resulting in a problem in print quality. Therefore, the wiping roller is moved to the intaglio plate side to obtain an appropriate wiping pressure. At this time, the roller side hub (22) following the wiping roller shaft (10) also moves, so that the driving side hub (20) and A shaft misalignment occurs. This axial misalignment is eliminated by the sliding of the intermediate hub (21).

  The movement of the wiping roller shaft during printing with this mechanism is constant on both the driving side and the operation side, and the wiping roller (11) must be parallel to the intaglio plate surface (2 '). However, due to uneven wear or the like of the wiping roller (11), a slight front-rear difference, that is, a deviation occurs between the driving side of the wiping roller shaft and the operation side of the wiping roller. FIG. 5 shows the movement of the wiping roller shaft during actual printing.

  FIG. 5 is a graph in which the position of the wiping roller (11) during printing is detected separately from the left and right by a sensor for detecting the position of the wiping roller shaft (10). The movement amount of 10), and the rotation axis of the wiping roller (11) is shown on the horizontal axis.

  The wiping roller rotation (25) in FIG. 5 is a line showing the state of rotation of the wiping roller shaft (10), and a pin is provided on the axis of the wiping roller shaft (10), and the pin is measured by a sensor. It is a method of measuring by detecting. The wiping roller driving side waveform (23) is a line indicating at which position the driving side shaft core of the wiping roller is pressed against the intaglio plate surface (2 '), and the measurement is performed on the wiping roller driving side shaft. A sensor is provided in the vicinity of, and the behavior of the shaft on the wiping roller driving side with respect to the intaglio plate surface (2 ′) is measured by the sensor. Similarly, the wiping roller operation side waveform (24) is a line indicating at which position the shaft side on the operation side of the wiping roller is pressed against the intaglio plate surface (2 ′), and the measurement is performed on the wiping roller. A sensor is provided in the vicinity of the operation side shaft, and the axis of the wiping roller operation side with respect to the intaglio plate surface (2 ′) is measured by the sensor.

  Therefore, if the intaglio plate surface (2 ′) and the axis of the wiping roller (10) are parallel, the wiping roller driving side waveform (23) and the wiping roller operation side waveform (24) have the same numerical value. When the numerical values are different, the wiping roller (10) is eccentric with respect to the intaglio plate surface (2 ').

  While the wiping roller (11) makes one rotation, the waveform (23) on the wiping roller driving side shows four peaks and four valleys during one rotation of the wiping roller. Further, from the waveform (24) on the operation side, it can be seen that the operation side of the wiping roller (11) is substantially parallel to the intaglio plate surface (2 '), but is slightly influenced by the driving side. Can be confirmed.

  The phenomenon in which peaks appear in this waveform results in that larger peaks and valleys appear in the waveform on the driving side of the wiping roller as the misalignment between the axis of the drive side hub (20) and the axis of the roller side hub (22) increases. .

  In this state, the pressing force contacting the intaglio plate surface (2 ') is different between the driving side of the wiping roller (11) and the operating side of the wiping roller (11), and the four peaks and valleys shown in FIG. Thus, it can be confirmed that the shaft center of the drive side hub (20) and the shaft center of the roller side hub (22) are misaligned. As a result, the intaglio plate surface (2 ') and the wiping roller (11) cannot be evenly contacted, and it is impossible to stably wipe off the ink on the intaglio plate surface, and stable printing quality cannot be maintained.

  The present invention aims to solve the above-mentioned problems. Specifically, a flexible joint is provided on a drive shaft in a wiping device of an intaglio printing press, and a mechanical frame on a driving side and a drive transmission bearing are provided. The connecting part is separated, a frame through hole is provided in the machine frame on the driving side, and a sub-frame for fixing the drive bearing is provided in the frame through hole so that it can be moved back and forth (sliding).

It is attached to the back.

Thus, the print quality can be improved.

  Further, adjustment by a person for controlling the drive transmission shaft and the wiping roller shaft is unnecessary, and wiping can be automated.

FIG. 7 shows a drive transmission shaft and a coupling in the present invention. FIG. 8 shows the angular relationship between the flexible joint and the coupling in the present invention. FIG. 9 shows a state in which the drive transmission shaft and the frame through hole are inserted in the present invention. FIG. 10 shows a side view of the control device portion in the present invention.

  First, the driving device according to the present invention will be described with reference to the plan view of FIG.

  In the wiping drive device, the drive from the wiping drive motor (5) is transmitted to the speed reducer (6), and is transmitted from the speed reducer (6) to the coupling (9) through the drive transmission shaft (7). 9) is transmitted to the wiping roller (11) through the wiping roller shaft (10) connected to the wiping roller, and the wiping roller is rotated by the transmitted drive.

  The drive to the wiping roller (11) transmitted from the wiping roller drive motor (5) is a drive that is the first point for smoothly transmitting the drive from the wiping drive motor (5) to the wiping roller (11). This is performed by the transmission means, the drive transmission shaft moving means as the second point, and the wiping roller moving means as the third point.

  The first point, the second point, and the third point for transmitting the drive from the wiping drive motor (5) to the wiping roller (11) will be described in detail below.

  First, drive transmission means, which is the first point for smoothly transmitting the drive from the wiping drive motor (5) to the wiping roller (11), will be described with reference to FIG.

  As a drive transmission means, a drive transmission shaft (7) joined at a desired position by a flexible joint (14), a wiping roller shaft (10), a drive transmission shaft (7), and a wiping roller shaft (10) are connected. Coupling (9).

  The joint position of the flexible joint (14) is a substantially intermediate position of the drive transmission shaft (7), in other words, a position closer to the drive side than the drive transmission bearing (8) attached to the drive transmission shaft (7). And

  The drive side hub (20) is attached to the tip of the drive transmission shaft (7) to which the drive transmission bearing (8) is attached, and the intermediate hub (21) is opposed to the two convex portions of the drive side hub (20). The two recesses are inserted into two recesses different from the recesses into which the drive side hub (20) of the intermediate hub (21) is inserted. The convex part slides and is fitted.

  In the best mode for carrying out the present invention, the two convex portions of the drive side hub (20) and the roller side hub (22) are described, but there may be many such as four or six locations. Absent.

  As shown in FIG. 8, the joint state of the flexible joint (14) is flexible on an extension line of 45 degrees, which is an intermediate angle between the convex part of the driving side hub (20) and the convex part of the roller side hub (22). It is desirable to connect in such a state that there is a joint part of the joint.

  The relationship between the axis of the normal drive transmission shaft (7) and the axis of the wiping roller shaft (10) is linear. The axis of the drive transmission shaft (7) and the axis of the wiping roller shaft (10) are linear. If they are shifted, backlash (backlash) is generated among the drive side hub (20), the intermediate hub (21), and the roller side hub (22). Due to the backlash (backlash), the drive side hub (20), the intermediate hub (21), and the roller side hub (22) do not rotate smoothly. The flexible joint (14) eliminates the backlash (backlash), and is a joint that connects the rotation axes for transmitting the rotation of the shaft core at an angle.

  Next, drive transmission shaft moving means as a second point for smoothly transmitting the drive from the wiping drive motor (5) to the wiping roller (11) will be described with reference to FIG.

  The drive transmission shaft moving means includes a drive transmission bearing (8) for inserting and supporting the drive transmission shaft (7) in the frame through hole of the drive side machine frame (13a) provided with the frame through hole (27). The drive bearing fixing subframe (16) for fixing the drive transmission shaft (7) via the drive transmission bearing (8), and the drive bearing fixing subframe (16 in the frame through hole of the machine frame (13a)) ) Is a slidable linear motion mechanism.

  In the conventional wiping drive device, as shown in FIG. 2, the drive-side machine frame (13a) and the drive transmission bearing (8) are fixed.

  In order to cope with the phenomenon that the diameter of the wiping roller is worn during printing, the wiping roller is moved to the intaglio plate side to obtain an appropriate wiping pressure as described above. At this time, the wiping roller shaft (10) Since the roller side hub (22) following this also moves, the drive side hub (20) is misaligned with the axis. This axial misalignment was eliminated by the sliding of the intermediate hub (21).

  However, if the axis of the drive transmission shaft (7) which should be linear and the axis of the wiping roller shaft (10) are misaligned, the drive side hub (20), the intermediate hub (21) and the roller side A state like backlash (backlash) occurs between the hubs (22). This backlash (backlash) is solved to some extent by providing the flexible joint which is the first point described above.

  However, since the drive-side machine frame (13a) and the drive transmission bearing (8) are fixed, the axis of the drive transmission shaft (7) and the axis of the wiping roller shaft (10) should be straight. The movable range of the shaft core was small, and it was not possible to cope with irregular wiping roller wear.

  Therefore, in order to increase the movable range of the shaft core, first, in the machine frame (13a) on the drive side, a part for attaching the drive bearing (8) to a part of the machine frame (13a) is cut into a square, A frame through hole (27) is provided.

  The drive transmission shaft (7) provided with the flexible joint (14) is fitted into the frame through hole (27) via the drive transmission bearing (8) and fixed to the drive bearing fixing subframe (16). To do.

  The sub-frame (16) for fixing the drive bearing to which the drive transmission shaft (7) is fixed is slid by a linear motion mechanism such as an LM guide (17) into the frame through hole (27) provided in the machine frame (13a). Fix it as possible.

  In order to maintain a linear state between the shaft center of the drive transmission shaft (7) and the shaft core of the wiping roller shaft (10), the subframe (16) for fixing the drive bearing is aligned with the rotation of the drive transmission shaft (7). Slides horizontally with respect to the horizontal axis of the machine frame (13a). Even when irregular fluctuations of the wiping roller occur, fine adjustment is possible by the slide amount, so that the linear state of the axis of the drive transmission shaft (7) and the axis of the wiping roller shaft (10) is maintained. Thus, the drive from the wiping drive motor (5) can be transmitted smoothly.

  Next, the wiping roller moving means as the third point for smoothly transmitting the driving from the wiping drive motor (5) to the wiping roller (11) will be described with reference to FIG.

  The wiping roller moving means includes a wiping roller shaft position detection sensor (26a, 26b) for detecting the position of the wiping roller (11) relative to the intaglio plate surface (2 '), and the wiping roller (11) relative to the intaglio plate surface (2'). A position adjustment mechanism that adjusts the position by pressure, and a position control unit that is connected to the wiping roller shaft position detection sensors (26a, 26b) and the position adjustment mechanism and controls the position of the wiping roller (11) relative to the intaglio plate surface (2 '). 19).

  This control device smoothly transmits the drive from the wiping drive motor (5) to the drive transmission shaft (7), the wiping roller shaft (10), and the wiping roller (11), so that the wiping roller bearings (12a, 12b) are transmitted. ) Of the wiping roller (2) with respect to the wiping roller (2) is moved to an appropriate position by separately pressing the drive side and the operation side.

  As described above, in order to smoothly transmit the drive from the wiping drive motor (5) to the wiping roller (11), the shaft core of the wiping roller shaft (10) and the shaft core of the drive transmission shaft (7) are connected. It is necessary to match it linearly.

  As a means for this, at the first point, the drive transmission shaft (7) is joined by the flexible joint (14), and at the second point, the drive bearing fixing subframe (16) is connected to the machine frame (13a). In the provided frame through hole (27), the LM guide (17) was fixed so as to be slidable.

  With these two means, the shaft core of the drive transmission shaft (7) and the shaft core of the wiping roller shaft (10) can be maintained in a linear state, but due to wear of the wiping roller (11) or the like. If there is no backlash between the hubs of the coupling (9) that occurs, this means will not be activated.

  Accordingly, the wiping roller bearings (12a, 12b) are driven so that backlash (backlash) does not occur in the drive side hub (20), intermediate hub (21) and roller side hub (22) of the coupling (9). A means for moving the front and rear positions with respect to the wiping roller (2) separately to the appropriate positions on the drive side and the operation side is provided.

  Therefore, a position adjusting mechanism for adjusting the front / rear position of the wiping roller bearings (12a, 12b) with respect to the wiping roller (2) by the pressure of the air cylinder, for example, a position adjusting air cylinder (18a, 18b) is installed on the machine frame (13a). ) And fix the front ends of the position adjusting air cylinders (18a, 18b) to the left and right of the drive bearing fixing sub-frame (16).

  Further, in order to align the axis of the wiping roller shaft (10) with the axis of the drive transmission shaft (7), the position of the wiping roller bearing (12a, 12b) fixing the wiping roller shaft is detected and adjusted. There is a need to. For this reason, the wiping roller shaft position detection sensors (26a, 26b) are attached to the rear of the wiping roller bearings (12a, 12b), and the wiping roller shaft position detection sensors (26a, 26b) are connected to the wiping roller bearings (12a, 12b). The front and rear positions of the wiping roller (2) are separately detected on the wiping roller driving side and the wiping roller operation side.

  Further, the position data detected by the wiping roller shaft position detection sensors (26a, 26b) is stored, and the shaft core of the wiping roller shaft (10) and the shaft core of the drive transmission shaft (7) are stored based on the position data. Position control for calculating the pressure of the position adjusting air cylinders (18a, 18b) for adjusting the position, or sending a control command for pressure adjustment of the position adjusting air cylinders (18a, 18b) based on the calculated pressure A part (19) is provided in the wiping remote control part on the operation stand which is not illustrated.

  In this way, the front and rear positions of the wiping roller bearings (12a, 12b) with respect to the wiping roller (2) are moved to the appropriate positions by separately pressing the driving side and the operating side, thereby allowing the coupling (9) to move. Backlash (backlash) does not occur in the drive-side hub (20), intermediate hub (21), and roller-side hub (22), or even if it occurs, the amount of deviation is minimal, so the drive transmission shaft (7) Drive transmission is possible by the first point and the second point for keeping the shaft center of the shaft and the shaft core of the wiping roller shaft (10) in a linear state.

  As a procedure for detecting and adjusting the wiping roller bearings (12a, 12b), first, the wiping roller bearings (12a, 12b) are detected by the wiping roller shaft position detection sensors (26a, 26b) attached to the rear of the wiping roller bearings (12a, 12b). The front-rear position of 12b) with respect to the wiping roller (2) is detected as position data separately on the drive side and the operation side, and the detected position data is sent to the position controller (19).

  Based on the position data sent, the position control unit (19) adjusts the position of the air cylinder (18a, 18a,) for aligning the axis of the drive transmission shaft (7) and the axis of the wiping roller shaft (10). The optimum pressure of 18b) is calculated. Based on the calculated pressure, the pressure of the position adjusting air cylinders (18a, 18b) is adjusted, and the front and rear positions of the wiping roller bearings (12a, 12b) with respect to the wiping roller (2) are changed between the driving side and the operating side. By pressing separately, it moves to an appropriate position, and the axis of the wiping roller shaft (10) and the axis of the drive transmission shaft (7) are aligned.

  As described above, in order for the wiping roller (11) to keep a uniform pressure against the intaglio plate surface (2 '), smooth driving from the wiping roller drive motor (5) to the wiping roller (11) is performed. Communication is essential. In order to smoothly transmit the drive from the wiping roller drive motor (5) to the wiping roller (11), the axis of the drive transmission shaft (7) and the axis of the wiping roller shaft (11) are linear. Need to be kept

  Further, in order to keep the shaft core of the drive transmission shaft (7) and the shaft core of the wiping roller shaft (11) in a linear state, the drive side hub (20) and the intermediate hub (21) of the coupling (9). And backlash (backlash) generated between the roller side hub (22) and the drive side hub (20), the intermediate hub (21) and the roller side hub (22) of the coupling (9). As described above, the drive transmission shaft (7), which is the first point, is joined by the flexible joint (14) and the drive bearing is the second point, as described above The fixing subframe (16) is slidably fixed by the LM guide (17) in the frame through hole (27) provided in the machine frame (13a).

  Further, the present invention may be configured by taking the means of the first point and the second point, but in addition to them, the position of the front and rear of the wiping roller (2) is controlled by the pressure of the air cylinder, which is the third point. The position adjustment air cylinders (18a, 18b) for adjustment may be provided on the machine frame (13a, 13b).

Although the LM guide is used as the motion mechanism, it is not limited to this as long as it has a slidable mechanism.

  Further, although the air cylinders (18a, 18b) are used as the position adjusting mechanism, the present invention is not limited to this, and a hydraulic cylinder and a ball screw mechanism may be applied.
