Description

  The present invention can be applied to a sheet-like workpiece including a film-like member such as plastic, paper, metal foil, composite paper, etc., which is continuously or intermittently displaced, up to an intermediate position of printing, die cutting, cutting, and thickness. When performing half-cutting, for example, when performing a series of processing related to each other across multiple stages of a work station that includes a support roll and a work roll that are rotationally driven together and are opposed to each other. The present invention relates to a position adjustment method of a work roll suitable for correcting a positional deviation of a processing position with respect to a sheet-like workpiece between the respective work stations, and a position adjustment apparatus used for carrying out the method. Yes, in particular, the work roll, and therefore the work provided there, while the connected state of the driven gear attached to the work roll to the drive side member remains unchanged The circumferential position of the stage, simply and easily, moreover, is to propose a precise adjustment technique.

  The sheet-like work is spread over a plurality of stages of a work station including, for example, a printing plate for rotary printing, a work roll provided with a punching blade for other half-cutting and other work means, and a support roll that is paired with the work roll. Work stations that are adjacent to each other when multiple sheets of multi-color printing, concentric shapes, etc., are performed under the cooperation of both rolls that run and work in pairs Therefore, for example, the relative displacement of the working means in the circumferential direction of the roll between the work station on the front stage and the work station on the rear stage is, for example, related to each other. When this occurs, a print misalignment, a cut misalignment, or the like occurs.

  For this reason, with respect to the occurrence of relative displacement of the work means, directly the work roll provided with the work means, the circumferential position of at least one work roll is adjusted to remove the displacement. It will be necessary.

  Therefore, conventionally, as illustrated in FIG. 7, in a work station St including a large-diameter support roll 111 and a smaller-diameter work roll 112, the two rolls 111 and 112 are respectively connected to the gears 114. In order to enable the adjustment of the circumferential position of the work roll 112, for example, the end face of the body portion of the work roll 112 when the support roll 111 is connected to the drive side and the drive roll is connected by meshing with the 115. While maintaining the meshing state of the gear 115 tightened and fixed by the bolt 116 and the support roll gear 114, the bolt 116 is loosened, the tightening of the gear 115 to the work roll 112 is released, and the work roll 112 is fixed to the bolt 116. At the same time, it has been proposed that the gear 115 can rotate relative to the gear 115 within the formation range of the arc-shaped hole 117 as shown in the perspective view of FIG.

  However, the position adjustment of the work roll according to this prior art is performed by loosening the bolt 116 and rotating the work roll 112 released from the restraint by the gear 115 by the operator's manual work. Therefore, there is a problem in that the trouble of the position adjustment work cannot be denied, and in addition, in order to make a fine and accurate adjustment, it is necessary to make adjustments that require repeated or relatively long time.

  The present invention has been made to solve such problems of the proposed technology, and the object of the present invention is to easily and quickly adjust the position of the work roll, and always accurately. An object of the present invention is to provide a work roll position adjustment method that can be used, and a position adjustment device that is used to implement the method.

  According to the present invention, there is provided a work roll position adjustment method comprising: a work roll connected to a drive side member via a gear; and a support roll; When the workpieces are sequentially passed through and the workpiece is subjected to the predetermined machining, the relative position between the work roll of the front work station and the work roll of the rear work station is corrected with the central axis of the work roll. Each bearing block that supports both ends of the bearing is displaced in parallel with the rotational displacement of the gear in the direction of the tangent to the support roll, and the peripheral surface of the work roll is rotated relative to the support roll. It is in.

  Here, the parallel displacement of each bearing block causes the bearing block contact surface of one clamping member of the pair of clamping members that sandwich the block from both sides to move forward and backward with respect to the block, and the other side. It is preferable to carry out by displacing the holding member by following the forward / backward displacement.

  Further, preferably, the forward / backward displacement of the bearing block contact surface of the holding member on one side is performed based on the approaching / separating displacement of the holding member along the cam surface with respect to the surface of the support roll.

  On the other hand, the follow-up displacement of the holding member on the other side is the movement of the holding member in the forward / backward displacement direction of the bearing block contact surface of the one-side holding member, or the support roll surface orthogonal to the forward / backward displacement direction. It is preferable that the movement is performed by approaching and moving away from.

  Further, the work roll position adjusting device according to the present invention is provided with a driven side gear that is always meshed with the drive side gear, and the work roll paired with the support roll has, for example, a rectangular parallelepiped shape or a cubic shape. Each bearing block is supported by each bearing block, and each bearing block is clamped from both sides by a pair of clamping members in a notch formed in the support frame, and either side clamping member forms an inclined cam surface It is possible to displace in the direction approaching and separating from the peripheral surface of the support roll opposite to the work roll under the contact with the notched edge surface, and based on this displacement, the clamping member, and consequently the bearing block thereof The contact surface is one side of the bearing block, for example, the vertical or horizontal side parallel to the plane passing through the central axis of each of the work roll and the support roll. The holding member on the other side is always pressed against the other side surface of the bearing block under the bias of the spring means, and one end portion is engaged with the holding member on the one side. The swing lever is attached to the holding frame.

  Here, the holding member on the other side is, for example, in a direction perpendicular to the other side surface of the bearing block in a vertical posture in relation to the biasing direction by the spring means, in other words, the forward and backward movement of the one side holding member. In addition to being movable in the direction, it is also possible to be movable in a direction orthogonal to the forward / backward direction.

  In such an apparatus, preferably, the support frame is provided with screw means for abutting against the other end of the swing lever and specifying the swing posture thereof. Also preferably, each swing lever for each bearing block is fixed on one shaft member. In this case, the screw means can be disposed only at one position corresponding to one of the swing levers.

  In the position adjusting method of the present invention, each bearing block that supports both ends of the work roll is supported in the extending direction of the tangent to the support roll, for example, in the horizontal direction, with the rotational displacement of the gear fixed to the work roll. Based on this, the working means, which can be the peripheral surface of the work roll, and hence the printing plate, punching blade, etc. provided there, is advanced in the direction in which it functions at a faster timing or slower. By rotating relative to the delay direction that will function at the timing as required, the position of the work roll can be adjusted accurately, easily and quickly regardless of the amount of adjustment. .

By the way, the parallel displacement of each bearing block in this case is the following movement of the holding member on the other side caused by the forward and backward displacement of the block contact surface, for example, the vertical surface of the holding member on one side that holds the block. When performing displacement, the position of the work roll can be easily and easily adjusted only by external operation of the holding member on one side, and it is always highly accurate without requiring the operator's feeling or experience. Can be done.

  When the above-mentioned forward / backward displacement of the holding member on one side is performed based on the approaching / separating displacement of the holding member along the inclined cam surface with respect to the surface of the support roll paired with the work roll, Under the selection of the inclination angle of the surface, the position adjustment of the work roll can be performed with higher accuracy even if the adjustment amount is small.

  On the other hand, in the case where the following displacement of the other side clamping member is performed by the movement of the one side clamping member in the advancing / retreating direction, the following displacement can be made sufficiently smooth. Also, when the holding member on the other side is moved by approaching and moving away from the surface of the support roll, for example, in the direction orthogonal to the advancing and retreating direction under the action of the inclined cam surface, for example, the bearing block is held by both the holding members. The force can be increased and the work roll can be held more stably.

  In the position adjusting device according to the present invention, one of the pair of clamping members that clamp the bearing block from both sides thereof in the notch provided in the support frame is formed as a notched edge surface that forms an inclined cam surface. The contact block is displaced in a direction approaching and separating from the peripheral surface of the support roll under the contact with the base, and based on this, the bearing block contact surface of the clamping member is moved forward and backward with respect to one side surface of the bearing block, Then, due to this forward / backward displacement, the other side clamping member is caused to follow the displacement under the sufficient clamping of the bearing block based on the action of the spring means, as described above for the position adjustment method of the work roll. The bearing block can be displaced in parallel with the rotational displacement of the gears. As a result, the position of the work roll and thus the working means provided there can be easily and quickly And it can be accurately adjusted.

  In this case, since the clamping member on one side also functions as a cam follower, an inclined surface corresponding to the cam surface is provided on the surface facing the notched inclined cam surface. The opposing surface to the bearing block is a flat surface that is in contact with the side surface of the block and has no inclination, for example, a vertical surface.

  Such a holding member on one side can be arranged in the notch so as to sandwich the inclined cam surface of the support frame from the inside to the outside of the notch, for example, with a substantially U-shaped cross section. Such an arrangement posture can be made substantially the same for the holding member on the other side.

  Also, here, by swinging and displacing a swinging lever having one end engaged with the holding member on one side with respect to the support frame, and changing the relative position of the holding member on one side with respect to the support roll, The position can be changed smoothly and easily from the outside, and the amount of advancement and retraction of the bearing block abutment surface of the clamping member is highly accurate in relation to the inclination angle of the inclined cam surface. Can be easily identified.

  In the apparatus as described above, the holding member on the other side is movable under the biasing force of the spring means in the other side of the bearing block, for example, the direction perpendicular to the heavy face or the direction along the other side. In this case, as described above, the holding member can be displaced to follow in the advancing / retreating direction of the one-side holding member or the direction approaching or separating from the support roll surface.

  In the latter case in which the other side clamping member is movable in the direction along the other side surface of the bearing block, the clamping member can be displaced following, for example, in the direction of the central axis of the bearing block.

  In addition, in the case where screw means for contacting the other end portion of the swing lever and specifying the swing posture thereof is provided, for example, by adjusting the screwing amount of the male screw member, the effect of the cam surface is compatible. Thus, fine adjustment of the work roll position can be performed more easily.

  By the way, when each rocking lever for each bearing block is fixed on one common shaft member, both the rocking levers are operated synchronously by rotating the shaft member, Each bearing block can be translated by the same amount at the same time.

  Therefore, when the one screw means is provided in relation to one of the swing levers, both the swing levers can be operated by operating the screw means, and the structure of the apparatus can be simplified. In addition, the apparatus can be miniaturized.

  FIG. 1 is a front view showing a working apparatus to which the position adjusting device according to the present invention is applied, with a support frame on the front side such as a supporting roller and a working roller removed, and FIG. 2 is an enlarged view of a main part of the working apparatus. It is a perspective view.

  In FIG. 1, reference numeral 1 denotes a housing that houses a drive system of a working device, and reference numerals 2 a, 2 b, 2 c, and 2 d denote sheet-like workpieces that protrude from the housing 1 and have a tape-like form, for example. 3a, 3b, and 3c are also provided on the housing so as to wind an unnecessary portion of the composite paper that is half-cut by a punching blade, for example. Respective take-up shafts are shown, and 4 denotes a product take-up shaft after a required processing is performed on the sheet-like workpiece.

  Here, a common support roll 5 is projected from the central portion of the housing 1, and a plurality of, in the figure, six nip rolls 6 are arranged around the support roll 5 at intervals in the circumferential direction. Then, between these nip rolls, three work rolls 7 a, 7 b, and 7 c that face the support roll 5 and are paired with the support roll 5 are provided so as to protrude from the housing 1.

  Here, the nip roll 6 functions to press the sheet-like workpiece fed continuously or intermittently from the winding roll against the support roll 5, and the work rolls 7a, 7b, 7c are all, for example, magnets. A punching blade 9 made of a flexible etching blade, which is an example of a working means, is magnetically attracted to the roll 8, and each working roll 7 a, 7 b, 7 c is under cooperation with a single common support roll 5. Thus, it functions to make a half cut on the sheet-like workpiece.

  For this reason, as shown in FIG. 1 and FIG. 2, each of the three work rolls 7 a, 7 b, 7 c disposed at a 90 ° interval around one support roll 5 and one common roll These support rolls 5 are paired at three locations to form three-stage work stations S1, S2, and S3.

According to such a configuration, each work station is provided with one support roll, and the structure is simplified as compared with a tandem type work apparatus in which the work stations are arranged in parallel with each other. It can be downsized.
In the figure, the working means serving as the punching blade 9 can be, for example, a printing plate such as offset printing, and the number of work stations can be appropriately increased or decreased as compared with that shown in the figure. You can also

  By the way, in the illustrated working apparatus, for example, the sheet-like workpiece W fed from one feeding shaft 2a has the respective work rolls 7a, 7b and 7c of the three stages of work stations S1, S2 and S3. In order to sequentially perform the punching process related to the above, it is assumed that the work roll 7b of the station S2 and, consequently, the punching blade 9 provided therewith are relative to the punching blades 9 of the other work rolls 7a and 7c. If there is a significant phase lag or advance, it will be necessary to correct it to enable proper machining in three stages as expected. 7a and 7c may occur in the same manner.

  Therefore, here, at least one work roll 7a, 7b, 7c (hereinafter represented by "work roll 7") supported at both ends by the front and rear support frames 11 via the bearing block 10 is shown in FIG. As shown in the enlarged view of FIG. 4 and the perspective view of FIG. 4, a gear 14 that is always meshed with the drive-side gear 13 is provided on one end portion of the central shaft 12 of the work roll 7. Under the state of being screwed and fixed via the boss portion 15, each bearing block 10 is paired in a notch 16 provided in the support frame 11 and extending in the radial direction of the support roll 5. Is supported with a sufficiently large force from both sides thereof.

  In this case, both of the holding members 17 and 18 have a substantially U-shaped cross section, and the holding frame 11 is interposed between the holding members 17 and 18 from the inside to the outside of the notch 16. However, for example, the sandwiching members 17 and 18 are notched as an aspect in which the cross-sectional shape thereof is a saddle shape and the inner surface of the flange portion is in contact with the edge surface of the notch 16. It can also be arranged in 16.

  As shown in FIG. 3, as shown in FIG. 3, the width of the notch 16 is gradually inserted toward the opening side of the notch 16. The inclined cam surface 19 that inclines linearly in the direction, and the opposing surface of the holding member 17 on one side straddling the inclined cam surface 19 with the cam surface 19 is inclined at the same angle in the same direction. As the linear inclined surface 20 in surface contact with the cam surface 19, the clamping member 17 is relatively displaced with respect to the cam surface 19 in the direction away from the surface of the support roll 5 and in the direction adjacent thereto, Under the contact between the cam surface 19 and the linear inclined surface 20, the clamping member 17, and hence the contact surface 21 that makes surface contact with one side surface of the bearing block 10, which is heavy in the figure, is formed into the block. Advance to the side And it can be displaced in both the direction and the backward direction.

  On the other hand, the holding member 18 on the other side in the notch 16 is on the side opposite to the notch cam surface 19 described above, and this is also the notch edge surface 22 which is a heavy face in the drawing, that is, the center of the work roll 7. The holding member 18 is arranged in a posture straddling a notch edge surface parallel to a plane including the axis and the center axis of the support roll 5, for example, one end is provided on the edge surface 22 of the notch 16. Bearing blocks by spring means 23 respectively seated on the bottom wall of the recess and on the bottom wall of the recess provided at the other end of the holding member 18 facing the notch edge surface 22, which also faces the notch Always energize to the 10 side. As a result, the abutting surface 24 of the clamping member 18 that comes into surface contact with the other heavy face of the bearing block 10 presses the block 10 toward the clamping member 17 on one side with a large force, and both clamping members The holding of the bearing block 10 by 17 and 18 is realized.

  Further, here, for example, FIG. 5 is an exploded perspective view of FIG. 4 in order to enable smooth and easy external operation of the holding member 17 on one side with respect to the support roll 5 as described above. As is clear from the figure, each flange member 17a sandwiching the support frame 11 of each holding member 17 on one side is formed by extending the material in a direction perpendicular to the block contact surface 21 thereof. While the notch portion 25 is provided, the intermediate portion is supported by the support frame 11 so as to be swingable. In the figure, the tip of the swing lever 26 that forms a pair with the support frame 11 being spaced apart is shared by them. The support frame 11 is provided with an arc-shaped hole 28 that allows the pin 27 to move in a circular arc.

  According to such a configuration, the oscillating lever 26 is oscillated and the engaging pin 27 at the tip thereof is displaced within the notch 25, so that the one-side clamping member 17 is brought along the cam surface 19. The holding member 17 can be moved forward and displaced in the direction of the other side holding member 18, that is, in the direction of the tangent to the support roll 5 together with the bearing block 10. In addition, the holding member 18 on the other side can be displaced backward together with the bearing block 10 against the spring force of the spring means 23 for biasing it.

  In the figure, the cam surface 19 of the notch 16 is an inclined surface that gradually narrows the notch width toward the notch opening, but the inclined direction of the inclined surface is opposite to that. In this case, the displacement direction of the holding member 17 on one side accompanying the displacement of the swing lever 26 can be set to the opposite direction to the above case.

  By the way, the required swing displacement of the swing lever 26 is screwed into a bracket 29 fixed to the support frame 11 while being biased in a direction perpendicular to the paper surface, as shown in FIG. By adjusting the screwing amount of the adjusting screw 30 that directly contacts the surface of the swinging lever 26 opposite to the pin 27 with respect to the fulcrum, it is as expected regardless of the amount of displacement. Preferably, the rocking lever 26 can be reliably held at a required position by specifying the screwing amount with the lock nack 31.

  Further, as shown in FIGS. 4 and 5, for example, as shown in FIG. 4 and FIG. 5, the adjustment screw 32 screwed into the support frame 11 is used for both swing levers. 26 can be brought into contact with the connecting rod 33 which brings about the mutual connection, and in this case, by operating the adjusting screw 32, the pair of swing levers can be swung directly by an equal amount. it can.

  Here, each of the pair of swing levers 26 is, for example, a pivot 34 that is rotatably supported by the support frame 11, or a cylindrical shape that is attached to the rotation itself around an axis fixed to the support frame 11. The support frame 11 is fitted on the pivot, and the width of the slit 35 formed in each lever 26 reaching the fitting hole to the pivot 34 is tightened by a bolt 36, so that both levers 26 are equal. By firmly fixing to the pivot 34 in a posture, the support frame 11 can be swingably supported.

  In this case, as shown in FIGS. 4 and 5, one pivot 34 is supported by the two support frames 11. When one of the swinging levers 26 is swung in common with each pair of swinging levers 26, all the swinging levers 26 can simultaneously swing at the same amount. Since the adjusting screws 30 and 32 are disposed only on one of the support frames 11, each of the holding members 17 on one side can be caused to perform a required displacement.

  4 and 5, two swing levers 26 are engaged with one holding member 17, but one is provided per one holding member 17 as illustrated in FIGS. 1 to 3. Of course, only the oscillating levers can be arranged, for example, inside the support frame 11. In this case as well, each oscillating lever can also be fixed on one common pivot 34. .

  Although not shown, for example, a spring member such as a beard spring or a coil spring disposed on the pivot is used to urge the swing lever in a direction in which it is always pressed against the tips of the adjustment screws 30 and 32. When the adjustment screws 30 and 32 are loosened, the return displacement of the rocking lever is made more reliable, and the tips of the adjustment screws 30 and 32 are screwed directly or indirectly into the rocking lever to The rocking lever can be surely displaced according to the screwing amount to the lever.

  For example, when the position of the work roll 7 of the work station S2 shown in FIG. 1 is adjusted with respect to the work roll 7 of the work station S1 shown in FIG. At the station S2, the set screw 40 of the work roll 7 is loosened, and the adjustment screws 30, 32 are tightened or loosened in a state in which the work roll 7 can be displaced in the width direction of the notch 16. The oscillating lever 26 is displaced, and based on this, the holding member 17 on one side is displaced along the notch cam surface 19 upward or downward in the drawing.

  This displacement of the pinching member 17 is performed under the sliding contact movement of the linear inclined surface 20 with respect to the cam surface 19, and as a result, the pinching member 17 advances in the direction in which the bearing block 10 advances or A horizontal displacement in the backward direction is performed.

  Here, as for the case where the clamping member 17 is moved forward, the bearing block 10 causes the clamping member 18 on the other side to resist the pressing force of the spring means 23 by the pressing force of the clamping member 17 on one side. Displaces horizontally while moving backward. In this case, since the gear 14 of the work roll 7 is always in mesh with the drive-side gear 13, such a horizontal displacement of the bearing block 10 causes, for example, normal rotation of the gear 13 with respect to the drive-side gear 13. Therefore, the punching blade 9 as the working means of the work roll 7 is provided on the holding member 17 with the rotational displacement in the direction and the rotational displacement in the normal rotation direction of the work roll itself. It is rotationally displaced in the advance direction over an angle range corresponding to the advance displacement position.

  Therefore, when the punching processing position at the work station S2 is located behind the processing position at the work station S1, for example, on the front side in the traveling direction of the sheet-like workpiece, it is clamped on one side. By moving the member 17 forwardly, the deviation can be easily and easily removed accurately.

  On the other hand, when the holding member 17 is moved backward, the bearing block 10 is horizontally displaced in the direction of the holding member 17 on the one side together with the holding member 18 on the other side under the action of the spring means 23. Thus, the gear 13 and the work roll 7 are rotationally displaced in the reverse direction. Accordingly, here, the punching blade 9 is rotationally displaced in the delay direction, and the punching position by the work roll 7 is relatively biased to the rear side in the running direction of the sheet-like workpiece. The work roll position is adjusted to an appropriate position.

  After finishing the position adjustment of the work roll 7 in this manner, the punching process for the sheet-like workpiece can be resumed by tightening the set screw 40 and restraining the work roll 7 at the operating position.

  The case where the position of the work roll 7 in the work station S2 is adjusted has been described above. This is because the position adjusting device described above is provided in at least one of the work stations S1 and S3. Can be performed in the same manner.

FIG. 6 is an enlarged view of a main part showing another embodiment of the apparatus according to the present invention.
Here, the notch 16 provided in the support frame 11 has an inclined cam surface 41 extending substantially parallel to the inclined cam 19 over which the holding member 17 straddles the edge surface over which the other holding member 18 straddles. In addition, a linear inclined surface 42 that comes into surface contact with the inclined cam surface 41 is provided on the other clamping member 18, and the clamping member 18 is moved to the support roll 5 side, which is the lower side in the drawing, by a spring member 43. In addition, the position of the clamping member 18 is regulated by the male screw member 44, and the configuration is different from that of the device in this respect.

For this reason, in this state, with the male screw member 44 loosened, the holding member 17 on one side is displaced relative to the bearing block 10, and the bearing block 10 is pressed against the holding member 18 on the other side. Under the action of the cam surface 41, the clamping member 18 escapes and displaces upward in the figure against the spring force of the spring member 43, and as a result, the clamping member 18 on the other side of the bearing block 10. In the figure in the direction of, horizontal displacement is performed.
Here, the upward displacement of the clamping member 18 in the direction away from the support roll 5 is smoothly performed under the action of a small force as the gradient of the cam surface 41 is reduced. .

  On the other hand, when the holding member 17 on one side is displaced backward, the bearing block 10 is pressed by the holding member 18 that is displaced downward in the drawing by the spring member 43, and the holding member 17 on the one side thereof. Will be displaced horizontally in the direction of.

  Even if the bearing block 10 is displaced in any direction, the gear 14 and the work roll 7 are rotated according to the displacement direction and the displacement amount of the bearing block 10. The punching blade 9 is also displaced in the same manner.

  After finishing the position adjustment of the work roll 7 in this way, the male screw member 44 is tightened to identify the position of the clamping member 18, and the set screw 40 is tightened to restrain the work roll 7 to the operating position. Work can be resumed.

  Incidentally, 45 in FIG. 6 is provided with a long hole provided in the holding member 17 on one side so as to extend in parallel with the inclination direction of the cam surface 19, and 46 is provided on the support frame 11. The pins that fit into the elongated holes 45 are shown, respectively, and both function to guide smooth displacement of the clamping member 17 under mutual cooperation.

In the above description, the work roll is provided with a punching blade as a work means. However, the work means can be a rotary printing plate, and the work roll itself can be a printing plate cylinder.
Further, the working means may be a die cutting blade, a cutting blade or the like for completely punching a sheet-like workpiece.
