  The above-mentioned conventional paper splicing device displaces the pressing arm by the air cylinder, presses the running web against the outer peripheral surface of the winding body by the pressing roller (brush roller), and winds the web using the sticking part. The web splicing is completed by cutting the web while the cutter is running after the web is pulled out from the winding body. By the way, when the running web is pressed against the outer peripheral surface of the new winding body by the movement of the pressing roller, the pressing roller is blown off by the repulsive force due to the contact and pressed against the outer peripheral surface of the winding body. The web may not be pressed by the roller, and paper splicing may not be performed.

  Moreover, the winding body described above is formed by winding a web into a roll shape, and the outer peripheral surface does not necessarily have a perfect circular shape, and some unevenness is generated. Therefore, when the web on which the pressing roller is traveling is pressed against the outer peripheral surface of the winding body, when the uneven portion of the winding body reaches the pressing roller, the pressing roller is blown away by contact with the uneven portion. In some cases, the web is not sufficiently pressed by the pressing roller against the outer peripheral surface of the winding body, and the paper splicing cannot be performed.

  In the paper splicing device described in Patent Document 1 described above, the outer peripheral surface of the pressing arm that supports the brush roller moves with the movement of the brush roller, and the output of the air cylinder that is an impact mitigating means is extended. By pushing the tip of the rod and retracting the output rod, the impact force caused by the collision between the brush roller and the outer peripheral surface of the winding body is reduced. For this reason, when the web is pressed against the winding body by the movement of the pressing roller, the pressing roller is prevented from rebounding and the web is not pressed sufficiently, and the paper splicing can be performed properly.

  However, even in this paper splicing device, when there is an uneven portion on the outer peripheral surface of the winding body, when this uneven portion reaches the pressing roller, the pressing roller is blown off by contact with the uneven portion, and the web Cannot be properly pressed against the outer peripheral surface of the winding body, and there is a problem that paper splicing cannot be performed. Although it is conceivable to increase the pressing force by the pressing roller, in this case, the winding body may be damaged by the pressing force of the pressing roller.

  The paper feeding device 11 has a reel stand on which two winding bodies (web rolls) are mounted, and a web drawn out from one winding body and traveling is used as a web of the other winding body. The web splicing device 21 can be continuously fed by connecting to the web. The infeed device 12 supplies the web of the paper feeding device 11 to the printing device 13 side. The printing apparatus 13 includes four printing units 22, 23, 24, and 25 for four ink colors, ie, Cyan, Magenta, yellow, and black, along the web running direction. Are arranged side by side. The drying device 14 is for drying the ink on the web that has been printed by the printing device 13, and the cooling device 15 is a suitable temperature for the web that stores excess heat after drying in the drying device 14. It is to cool down. The web pass device 16 conveys a dried and cooled web, and the folding device 17 cuts the web after being vertically folded and folds it to a predetermined size to form a folded book. The paper discharge device 18 carries out the folded or folded book outside the apparatus.

The multi-color printing is performed, and the printed web W is dried by the drying device 14, cooled by the cooling device 15, and a folded book is created by the folding device 17 conveyed through the web pass device 16. It is carried out by the paper device 18.

  Here, in the offset rotary printing press of the present embodiment, the paper feeding device 11 and the paper splicing device 21 provided in the paper feeding device 11 will be described in detail.

  In the paper feeding device 11, as shown in FIG. 3, a main shaft 31 is rotatably supported by a pair of left and right frames (not shown) and can be rotated by a turning device (not shown). The main shaft 31 is connected to the base end portions of a pair of left and right support arms 32 a and 32 b and is movable along the axial direction of the main shaft 31. Support shafts 33 and 34 are attached to the distal ends of the support arms 32a and 32b, respectively, and the first winding body R1 and the second winding body R2 are sandwiched from outside in the axial direction by the support shafts 33 and 34. Can be supported rotatably.

  A base plate 35 is fixed to the main shaft 31 so as to intersect the support arms 32a and 32b, air cylinders 36 and 37 are attached to the respective ends of the base plate 35, and guide rollers 38 and 39 are attached to the distal ends thereof. ing. A guide roller 40 is rotatably provided facing the guide roller 38.

  A paper splicing device 21 is disposed between the guide rollers 38 and 40. In the paper splicing device 21, a pair of upper and lower guide rails 41 and 42 are fixed to a pair of left and right frames, and a slide plate 43 is movably supported on the guide rails 41 and 42, and a drive motor 44. Thus, it can be moved via a cable (not shown). On the slide plate 43, a paster roller 45 is rotatably supported at an intermediate position in the vertical direction, and guide rollers 46 and 47 are rotatably supported on the upper and lower sides thereof. A cutter 48 adjacent to the paster roller 45 is supported. Is provided. The paster roller 45, the guide rollers 46 and 47, and the cutter 48 are disposed so as to face the second winding body R2. The paster roller 45 is a rubber roller or a sponge roller, and has an elastically deforming portion having elasticity at the outer peripheral portion.

  Therefore, when the web W1 is pulled out from the first winding body R1 (or the second winding body R2) and printing is performed, the web W1 from the first winding body R1 is guided by the guide rollers 38, The paper splicing device 21 is in a standby state at the standby position. Then, when performing web splicing by pressing the web W1 that is drawn from the first winder R1 by the paper splicer 21 against the outer peripheral surface of the second winder R2, the slide plate 43 is moved by the drive motor 44. By doing so, as shown in FIG. 4, the paper splicing device 21 can be moved to a contact position approaching the outer peripheral surface of the second winding body R2, and at this time, the web W1 traveling by the paster roller 45 is moved. The paper splicing can be performed by pressing against the outer peripheral surface of the second winding body R2.

  That is, as shown in FIG. 1, a base end portion of a paster arm 52 as a pressing arm is rotatably supported by a support shaft 51 on a slide plate 43 as a frame. A paster roller 45 as a pressing member is rotatably supported. In addition, an air cylinder (fluid cylinder) 53 as a roller moving means is mounted on the slide plate 43, and the distal end portion of the cylinder rod 54 is connected to the intermediate portion of the paster arm 52. The air cylinder 53 is divided into two chambers 53a and 53b by a piston connected to the cylinder rod 54, and an air supply / discharge device 55 is connected to each of the chambers 53a and 53b.

  Further, the slide plate 43 is provided with a damper device 56 as a spring restraining means, and the distal end portion of the drive rod 57 is connected to the intermediate portion of the paster arm 52. The damper device 56 moves at a high speed in the direction in which the drive rod 57 extends, and a reaction force is generated in the direction in which the drive rod 57 contracts to reduce the moving speed, thereby limiting the amount of movement. can do. That is, the damper device 56 is partitioned into two chambers 56a and 56b by a piston connected to the drive rod 57, and each of the chambers 56a and 56b has a small-diameter connecting hole 56c and a large-diameter and has a check valve. It communicates with the connecting hole 56d and is filled with hydraulic oil.

  Accordingly, when air is supplied to the chamber 53a of the air cylinder 53 from the state where the paster roller 45 is in the standby position by the air supply / discharge device 55, the cylinder rod 54 extends as shown in FIG. Is rotated, and the paster roller 45 can be moved to the pressing position for pressing the outer periphery of the second winding body R2. At this time, the paster roller 45 tries to rebound due to the impact coming into contact with the outer peripheral surface of the second winding body R2, but when the drive rod 57 contracts in the damper device 56, the check hole opens the connecting hole 56d. Is closed, and the hydraulic oil in the chamber 56a flows into the chamber 56b through the connecting hole 56c, so that the moving speed and the moving amount thereof are limited, and the amount of rebound from the outer peripheral surface of the second winding body R2 in the paster roller 45 Can be suppressed.

  By the way, as shown in FIG. 6, 2nd winding body R2 (R1) is formed by winding web W2 (W1) in roll shape, and the edge part of web W2 has the cut | interruption T1. While being temporarily fixed by a plurality of tabs T, a double-sided adhesive tape S is affixed. Therefore, as described above, the web W1 running by the paster roller 45 is pressed against the outer peripheral surface of the second winding body R2 rotating at the same peripheral speed, and the double-sided adhesive of the second winding body R2 is pressed. When the tape S moves to the surface of the web W1, the web W1 and the second winding body R2 are in close contact with each other, and the end of the web W2 of the second winding body R2 is pulled by the web W1, thereby causing a break. The tab T is cut from T1, and the web W2 is pulled out from the second winding body R2.

  In this case, the paster roller 45 presses the running web W1 against the outer peripheral surface of the rotating second winding body R2 at least for one rotation of the second winding body R2. In general, the wound bodies R1 and R2 are formed by winding the webs W1 and W2 in a roll shape, but the outer peripheral surface is not necessarily a perfect circle and may have irregularities. For this reason, when the uneven portion of the second winding body R2 reaches the paster roller 45 when the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2, the paster roller 45 And the web W1 may not be properly pressed against the outer peripheral surface of the second winding body R2.

  However, in the present embodiment, the damper device 56 serving as the above-described splash suppressing means can suppress the splash of the paster roller 45 due to the impact received from the second winding body R2. That is, when the uneven portion exists on the outer peripheral surface of the second winding body R2, the damper device 56 causes the paster roller 45 to be affected by the impact received from the second winding body R2 when the uneven portion contacts the paster roller 45. No splashing can be suppressed.

  More specifically, as shown in FIG. 3, the web W1 is drawn from the first winding body R1 by the paper splicing device 21 from the state where the web W1 is drawn out and printed, and then the second winding body R2. When the paper splicing is performed by pressing against the outer peripheral surface of the paper, first, the paper splicing device 21 (slide plate 43) in the standby position is moved by the drive motor 44 to the contact position as shown in FIG. The web W1 traveling by 45 is supported and moved to the outer peripheral surface side of the second winding body R2.

  Next, as shown in FIG. 1, the air cylinder 53 is operated by the air supply / discharge device 55 as shown in FIG. 2 from the state where the paper splicing device 21 is in the contact position and the paster roller 45 is in the standby position. By doing so, the paster arm 52 is rotated, and the paster roller 45 is moved to the pressing position to be pressed against the outer peripheral surface of the second winding body R2 while supporting the web W1. In this case, the second winding body R2 rotates at the same peripheral speed with respect to the running web W1, and the double-sided adhesive tape S (see FIG. 6) of the second winding body R2 is the paper splicing device. Immediately after passing through 21, it is preferable to move the paster roller 45 and press the web W1 against the outer peripheral surface of the second winding body R2.

  Then, since the web W1 travels and the second winding body R2 rotates while the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2, the double-sided adhesive tape of the second winding body R2 is rotated. When S reaches the paper splicing device 21 again, the web W1 traveling and the end of the web W2 in the second winding body R2 are connected by the double-sided adhesive tape S, and the web W1 of the web W2 of the second winding body R2 is connected by the web W1. By pulling the end portion, the tab T is cut from the cut line T1, the web W2 is pulled out from the second winding body R2, the web W1 and the web W2 travel together, and the web W1 is cut by the cutter 48. This completes the paper splicing operation.

  During this paper splicing operation, the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2, and then the second winding body R2 rotates and the double-sided adhesive tape S reaches the paper splicing device 21. During this time, when the uneven portion of the second winding body R2 reaches the paster roller 45, an impact force acts on the paster roller 45. However, since the damper device 56 is coupled to the paster arm 52, even if an impact force acts on the uneven portion of the second winding body R <b> 2 with respect to the paster roller 45, the paster roller 45 is moved by the damper device 56. Splash is suppressed. That is, when a contraction force acts on the drive rod 57 from the concave and convex portion of the second winding body R2 via the paster arm 52 in the damper device 56, the connection hole 56d is closed by the check valve, and the hydraulic oil in the chamber 56a Flows into the room 56b through the connecting hole 56c, and thus the moving speed and moving amount thereof are limited. Therefore, the paster arm 52 hardly rotates, and the paster roller 45 suppresses the amount of rebound from the outer circumferential surface of the second winding body R2, and continuously presses the web W1 against the outer circumferential surface of the second winding body R2. be able to.

  As described above, in the paper splicing device according to the first embodiment, the web W1 drawn out from the first winding body R1 is pressed against the outer peripheral surface of the rotating second winding body R2 to perform paper splicing. In the joining device 21, a paster roller 45 capable of pressing the web W1 from the first winding body R1 to the outer circumferential surface of the second winding body R2, and the paster roller 45 from the outer circumferential surface of the second winding body R2. An air cylinder 53 movable between a separated standby position and a pressing position to be pressed, and a damper device 56 as a spring restraining means for suppressing splashing of the paster roller 45 due to an impact received from the second winding body R2 are provided. Yes.

  Therefore, when the paster roller 45 is moved from the standby position to the pressing position by the air cylinder 53 and the web W1 from the first winding body R1 is pressed against the outer peripheral surface of the second winding body R2, the damper device 56 2 In order to suppress the splash of the paster roller 45 due to the impact received from the winding body R2, the web W1 from the first winding body R1 can be properly pressed against the outer peripheral surface of the second winding body R2, and the web Paper splicing can be performed smoothly by properly splicing.

  Further, in the paper splicing device and the printing machine of the present embodiment, when the uneven portion is present on the outer peripheral surface of the second winding body R2, the damper device 56 performs the second operation when the uneven portion is in contact with the paster roller 45. Splashing of the paster roller 45 due to an impact received from the winding body R2 is suppressed. Therefore, when the paster roller 45 is moved to the pressing position by the air cylinder 53 and the web W1 from the first winding body R1 is pressed against the outer peripheral surface of the second winding body R2, the concavo-convex portion contacts the paster roller 45. Even so, the damper device 56 appropriately presses the web W1 from the first winding body R1 against the outer peripheral surface of the second winding body R2 in order to suppress the splash of the paster roller 45 due to the impact at this time. Can do.

  In this embodiment, the paster roller 45 is rotatably supported at the distal end portion of the paster arm 52 whose base end portion is rotatably supported by the slide plate 43, and the paster arm can be rotated by the air cylinder 53.

  FIG. 7 is a schematic diagram illustrating a paster roller in the paper splicing device according to the second embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the member which has the same function as what was demonstrated in the Example mentioned above, and the overlapping description is abbreviate | omitted.

  In the paper splicing device in the paper feeding device of the printing press according to the second embodiment, as shown in FIG. 7, the base end portion of the paster arm 52 is rotatably supported on the slide plate 43 by the support shaft 51. A paster roller 45 is rotatably supported at the tip of the paster arm 52. In addition, a hydraulic cylinder (fluid cylinder) 61 as a roller moving means is mounted on the slide plate 43, and the distal end portion of the cylinder rod 62 is connected to the intermediate portion of the paster arm 52. The hydraulic cylinder 61 is connected with an air hydro unit 63 as a spring restraining means, and an air supply / discharge device 64 is connected to the air hydro unit 63. In the air hydro unit 63, the converter and the valve unit are integrated in a compact manner, and the air pressure of the air supply / discharge device 64 is converted into the same pressure to drive the hydraulic cylinder 61. Therefore, the problem due to the compressibility of air is solved by hydraulic pressure while maintaining the high speed of air. Therefore, the air hydro unit 63 moves at a high speed due to the nature of air in the direction in which the cylinder rod 62 extends, and reduces the moving speed due to the incompressibility of hydraulic pressure in the direction in which the cylinder rod 62 contracts. Therefore, the amount of movement can be limited.

  Accordingly, when the paper splicing device of the present embodiment is in the contact position where the web W1 is pressed against the outer peripheral surface of the second winding body R2 to perform paper splicing, the air supply / discharge device 64 hydraulically presses the air through the air hydro unit 63. By actuating the cylinder 61, the paster arm 52 is rotated, and the paster roller 45 is moved to a pressing position for pressing against the outer circumferential surface of the second winding body R2 while supporting the web W1. In this case, the second winding body R2 rotates at the same peripheral speed with respect to the running web W1, and immediately after the double-sided adhesive tape of the second winding body R2 passes through the paper splicing device, It is preferable to move the paster roller 45 and press the web W1 against the outer peripheral surface of the second winding body R2.

  At this time, the paster roller 45 tries to rebound due to the impact coming into contact with the outer circumferential surface of the second winding body R2, but the paster roller 45 is separated from the outer circumferential surface of the second winding body R2 by the air hydro unit 63. The moving speed and the moving amount are limited, and the amount of rebound from the outer peripheral surface of the second winding body R2 in the paster roller 45 can be suppressed.

  Since the web W1 travels and the second winding body R2 rotates while the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2, the double-sided adhesive tape of the second winding body R2 is rotated. When the sheet reaches the paper splicing device 21 again, the web W1 traveling and the end of the web W2 in the second winding body R2 are connected by the double-sided adhesive tape S, and the end of the web W2 of the second winding body R2 is connected by the web W1. When the portion is pulled, the tab is cut from the cut, the web W2 is pulled out from the second winding body R2, the web W1 and the web W2 travel together, and the web W1 is cut by the cutter 48. This completes the paper splicing operation.

  Further, at this time, the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2 until the second winding body R2 rotates and the double-sided adhesive tape reaches the paper splicing device. When the uneven portion of the second winding body R2 reaches the paster roller 45, an impact force acts on the paster roller 45. However, since the air hydro unit 63 is connected to the hydraulic cylinder 61, even if an impact force acts on the concavo-convex portion of the second winding body R <b> 2 with respect to the paster roller 45, the paster roller 45 remains in the air hydro unit. 63 prevents splashing. Therefore, the paster arm 52 hardly rotates, and the paster roller 45 suppresses the amount of rebound from the outer circumferential surface of the second winding body R2, and continuously presses the web W1 against the outer circumferential surface of the second winding body R2. be able to.

  As described above, in the paper splicing device according to the second embodiment, the paster roller 45 capable of pressing the web W1 from the first winding body R1 to the outer peripheral surface of the second winding body R2, and the paster roller 45 is connected to the second winding body R2. 2 Hydraulic cylinder 61 movable between a standby position separated from the outer peripheral surface of the winding body R2 and a pressing position to be pressed, and a splash suppression that suppresses splashing of the paster roller 45 due to an impact received from the second winding body R2. An air hydro unit 63 is provided as a means.

  Therefore, when the paster roller 45 is moved to the pressing position by the hydraulic cylinder 61 and the web W1 from the first winding body R1 is pressed against the outer peripheral surface of the second winding body R2, the unevenness of the second winding body R2 is detected. Even if the portion contacts the paster roller 45, the air hydro unit 63 suppresses the web roller W1 from the first winding body R1 to the second winding body R2 in order to suppress the splash of the paster roller 45 due to the impact at this time. Can be appropriately pressed against the outer peripheral surface of the paper, and the paper splicing operation can be performed smoothly.

  And the splash suppression means is comprised by the air hydro unit 63, the splash of the paster roller 45 can be suppressed with respect to the impact received from 2nd winding body R2 using the existing apparatus, Also, it is possible to cope with a large impact received from the second winding body R2.

  FIG. 8 is a schematic diagram illustrating a paster roller in a paper splicing device according to a third embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the member which has the same function as what was demonstrated in the Example mentioned above, and the overlapping description is abbreviate | omitted.

  In the paper splicing device in the paper feeding device of the printing press of the third embodiment, as shown in FIG. 8, the base end portion of the paster arm 52 is rotatably supported by the slide plate 43 by the support shaft 51. A paster roller 45 is rotatably supported at the tip of the paster arm 52. An air cylinder 53 is attached to the slide plate 43, and the tip of the cylinder rod 54 is connected to the intermediate portion of the paster arm 52. The air cylinder 53 is connected with an air supply / discharge device 55.

  Further, as the bounce suppressing means, a virtual outer peripheral face setting means for setting a virtual outer peripheral face from the degree of unevenness of the outer peripheral face in the second winding body R2 and a paster roller 45 moved by the air cylinder 53 are pressed against the virtual outer peripheral face. Positioning means for positioning at a position is provided. In the present embodiment, as the virtual outer peripheral surface setting means, a laser sensor 71 that measures the distance from a predetermined position to the outer peripheral surface of the second winding body R2, and the second winding body based on the measurement result of the laser sensor 71. A control device 72 for setting the virtual outer peripheral surface of R2 is provided. Further, a stopper mechanism 73 capable of adjusting the stop position is connected to the paster arm 52 as positioning means, and can be operated by the control device 72.

  Therefore, when the paper splicing device of the present embodiment is in the contact position where the web W1 is pressed against the outer peripheral surface of the second winding body R2 to perform the paper splicing, the laser sensor 71 has the entire circumference of the second winding body R2. The distance from the predetermined position to the outer circumferential surface of the second winding body R2 is measured, and the control device 72 sets the virtual outer circumferential surface of the second winding body R2 based on the measurement result. That is, the second winding body R2 does not have a perfect circular shape when the outer peripheral surface has an uneven portion, but its radius varies along the circumferential direction. For this reason, the control device 72 calculates the radius of variation in the circumferential direction of the second winding body R2 based on the measurement result of the laser sensor 71, and calculates the virtual radius by averaging the radius of variation in the circumferential direction. Then, a virtual outer peripheral surface is set from this virtual radius.

  When the virtual outer peripheral surface of the second winding body R <b> 2 is set by the control device 72, the control device 72 adjusts the positioning stop position of the paster arm 52 by the stopper mechanism 73. The positioning stop position of the paster arm 52 is a pressing position where the paster roller 45 contacts the virtual outer peripheral surface of the second winding body R2 when the paster roller 45 is moved by the air cylinder 53 via the paster arm 52. . When the air cylinder 53 is actuated to rotate the paster arm 52 and the paster roller 45 is moved to the outer peripheral surface side of the second winding body R2 while supporting the web W1, the paster roller 45 is moved. Is moved to a pressing position where the virtual outer peripheral surface of the second winding body R2 is pressed by the stopper mechanism 73. In this case, the second winding body R2 rotates at the same peripheral speed with respect to the running web W1, and immediately after the double-sided adhesive tape of the second winding body R2 passes through the paper splicing device, It is preferable to move the paster roller 45 and press the web W1 against the outer peripheral surface of the second winding body R2.

  At this time, since the stop position of the paster roller 45 is set by the stopper mechanism 73, there is little impact coming into contact with the outer peripheral surface of the second winding body R2, and the second winding body R2 in the paster roller 45 has a small impact. The amount of rebound from the outer peripheral surface can be suppressed.

  The paster roller is a rubber roller or a sponge roller, and has an elastically deforming portion having elasticity at the outer peripheral portion. Therefore, even if the paster roller stops at the virtual outer peripheral surface of the second winding body R2, the web W1. Can be pressed against the outer peripheral surface of the second winding body R2, and when the web W1 travels and the second winding body R2 rotates, the double-sided adhesive tape of the second winding body R2 reaches the paper splicing device 21 again. And the end of the web W2 in the second winding body R2 is connected by the double-sided adhesive tape S, and the end of the web W2 of the second winding body R2 is pulled by the web W1, The tab is cut, the web W2 is pulled out from the second winding body R2, the web W1 and the web W2 travel together, and the web W1 is cut by the cutter 48 to complete the paper splicing operation.

  Further, at this time, the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2 until the second winding body R2 rotates and the double-sided adhesive tape reaches the paper splicing device. When the uneven portion of the second winding body R2 reaches the paster roller 45, an impact force acts on the paster roller 45. However, the paster roller stops at the virtual outer peripheral surface of the second winding body R2 by the stopper mechanism 73 and has an elastically deforming portion on the outer peripheral portion. The impact force received from the concavo-convex part of the body R2 is very small, and splashing is suppressed by the elastic deformation part. Therefore, the paster arm 52 hardly rotates, and the paster roller 45 suppresses the amount of rebound from the outer circumferential surface of the second winding body R2, and continuously presses the web W1 against the outer circumferential surface of the second winding body R2. be able to.

  As described above, in the paper splicing device according to the third embodiment, the paster roller 45 capable of pressing the web W1 from the first winding body R1 to the outer peripheral surface of the second winding body R2, and the paster roller 45 is connected to the second winding body R2. 2 Air cylinder 53 movable between a standby position separated from the outer peripheral surface of the winding body R2 and a pressing position to be pressed, and a splash suppression that suppresses splashing of the paster roller 45 due to an impact received from the second winding body R2. A laser sensor 71, a control device 72, and a stopper mechanism 73 are provided as means.

  Therefore, the laser sensor 71 measures the distance from the predetermined position to the outer peripheral surface of the second winding body R2 over the entire circumference of the second winding body R2, and the control device 72 determines the second winding based on the measurement result. The virtual outer peripheral surface of the body R2 is set, and the positioning stop position of the paster arm 52 by the stopper mechanism 73 is adjusted. In this state, when the paster arm 52 is moved by the air cylinder 53, the paster roller 45 stops at a position in contact with the virtual outer peripheral surface of the second winding body R2, and the first roller contact with the virtual outer peripheral surface of the second winding body R2. Even if the web W1 from the winding body R1 is pressed and the uneven portion of the second winding body R2 comes into contact with the paster roller 45, the paster roller 45 receives from the uneven portion of the second winding body R2. Since the impact force becomes small and the elastic deformation part suppresses the splashing, the web W1 from the first winding body R1 can be properly pressed against the outer peripheral surface of the second winding body R2, and the paper splicing work can be performed smoothly. Can be done.

  FIG. 9 is a schematic diagram illustrating a paster roller in a paper splicing device according to a fourth embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the member which has the same function as what was demonstrated in the Example mentioned above, and the overlapping description is abbreviate | omitted.

  In the paper splicing device in the paper feeding device of the printing machine according to the fourth embodiment, as shown in FIG. 9, the base end portion of the paster arm 52 is rotatably supported on the slide plate 43 by the support shaft 51. A paster roller 45 is rotatably supported at the tip of the paster arm 52. An air cylinder 53 is attached to the slide plate 43, and the tip of the cylinder rod 54 is connected to the intermediate portion of the paster arm 52. The air cylinder 53 is connected with an air supply / discharge device 55.

  Further, as a bounce suppressing means, a stopper mechanism 81 as positioning means for positioning the paster roller 45 moved by the air cylinder 53 at a pressing position with the outer peripheral surface of the second winding body R2, and a paster positioned at the pressing position. An absorption mechanism 82 that allows minute movement of the second winding body R2 in the radial direction of the roller 45 is provided. The stopper mechanism 81 is connected to the paster arm 52. The position of the outer peripheral surface is obtained in advance from the radius of the second winding body R2, and the paster roller 45 presses the outer peripheral surface of the second winding body R2. The amount of rotation of the paster arm 52 is regulated so as to stop at the position where it moves. The absorption mechanism 82 has a long hole 52 a formed at the tip of the paster arm 52, a rotation shaft 45 a of the paster roller 45 fitted into the long hole 52 a, and a second winding of the paster roller 45 with respect to the paster arm 52.

  Accordingly, when the paper splicing device of the present embodiment is in the contact position where the web W1 is pressed against the outer peripheral surface of the second winding body R2 to perform paper splicing, the air supply / discharge device 55 operates the air cylinder 53. Then, the paster arm 52 is rotated, and the paster roller 45 is moved to the pressing position for pressing against the outer peripheral surface of the second winding body R2 while supporting the web W1. In this case, the second winding body R2 rotates at the same peripheral speed with respect to the running web W1, and immediately after the double-sided adhesive tape of the second winding body R2 passes through the paper splicing device, It is preferable to move the paster roller 45 and press the web W1 against the outer peripheral surface of the second winding body R2.

  At this time, since the stop position of the paster roller 45 is set by the stopper mechanism 81, there is little impact coming into contact with the outer peripheral surface of the second winding body R2, and the second winding body R2 of the paster roller 45 has a small impact. The amount of rebound from the outer peripheral surface can be suppressed. The paster roller 45 slightly contacts the outer peripheral surface of the second winding body R2, but the impact force with which the paster roller 45 contacts is absorbed by the absorption mechanism, and the outer peripheral surface of the second winding body R2 in the paster roller 45 is absorbed. The amount of rebound from can be suppressed.

  Since the web W1 travels and the second winding body R2 rotates while the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2, the double-sided adhesive tape of the second winding body R2 is rotated. When the sheet reaches the paper splicing device 21 again, the web W1 traveling and the end of the web W2 in the second winding body R2 are connected by the double-sided adhesive tape S, and the end of the web W2 of the second winding body R2 is connected by the web W1. When the portion is pulled, the tab is cut from the cut, the web W2 is pulled out from the second winding body R2, the web W1 and the web W2 travel together, and the web W1 is cut by the cutter 48. This completes the paper splicing operation.

  Further, at this time, the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2 until the second winding body R2 rotates and the double-sided adhesive tape reaches the paper splicing device. When the uneven portion of the second winding body R2 reaches the paster roller 45, an impact force acts on the paster roller 45. However, since the absorbing mechanism 82 is provided between the paster arm 52 and the paster roller 45, even if an impact force acts on the uneven portion of the second winding body R2 against the paster roller 45, the paster roller. In 45, splashing is suppressed. That is, when the paster roller 45 is pushed by the uneven portion of the second winding body R2, the paster roller 45 moves through the long hole 52a against the urging force of the spring member 83, and absorbs the impact force. You can suppress the splash. Therefore, the paster arm 52 hardly rotates, and the web W1 can be continuously pressed against the outer peripheral surface of the second winding body R2.

  As described above, in the paper splicing device according to the fourth embodiment, the paster roller 45 capable of pressing the web W1 from the first winding body R1 to the outer peripheral surface of the second winding body R2, and the paster roller 45 is connected to the second winding body R2. 2 Air cylinder 53 movable between a standby position separated from the outer peripheral surface of the winding body R2 and a pressing position to be pressed, and a splash suppression that suppresses splashing of the paster roller 45 due to an impact received from the second winding body R2. A stopper mechanism 81 and an absorbing mechanism 82 are provided as means.

  Accordingly, when the paster roller 45 is moved to the pressing position by the hydraulic cylinder 61 and the web W1 from the first winding body R1 is pressed against the outer peripheral surface of the second winding body R2, the paster arm 52 is in the stop position. Even if the concavo-convex portion of the second winding body R2 is in contact with the paster roller 45 by the stopper mechanism 81, there is little impact on the outer peripheral surface of the second winding body R2, and the impact at this time Since the absorbing mechanism 82 suppresses the splashing of the paster roller 45 caused by the web W1, the web W1 from the first winding body R1 can be properly pressed against the outer peripheral surface of the second winding body R2, and the paper splicing work can be performed smoothly.

  FIG. 10 is a schematic diagram illustrating a winding body used in a paper splicing device according to a fifth embodiment of the present invention, and FIG. 11 is a schematic diagram illustrating an operating state of a paster roller in the paper splicing device according to the fifth embodiment. . In addition, the same code | symbol is attached | subjected to the member which has the same function as what was demonstrated in the Example mentioned above, and the overlapping description is abbreviate | omitted.

  In the paper splicing device in the paper feeding device of the printing machine according to the fifth embodiment, as shown in FIG. 10, the winding body R2 is configured by winding the web W2 by a predetermined length, and in the circumferential direction. A double-sided pressure-sensitive adhesive tape S as a paper joint is provided on the surface separated from the position of the maximum radius D by a predetermined distance L on the upstream side in the drawing direction of the web W2 (arrow A in FIG. 10).

  That is, as described above, the second wound body R2 is formed by winding the web W2 in a roll shape, but the outer peripheral surface is not necessarily a perfect circle but has irregularities. Therefore, when the paster roller 45 presses the web W1 against the outer peripheral surface of the second winding body R2, when the convex portion of the second winding body R2 reaches the paster roller 45, the paster roller 45 The double-sided pressure-sensitive adhesive tape S may cause the web W1 and the web W2 of the second winding body R2 to not be properly spliced.

  Therefore, in the present embodiment, when the convex portion 91 is formed at the position of the maximum radius D on the outer peripheral surface of the second winding body R2, the predetermined distance L from the convex portion 91 to the upstream side in the drawing direction of the web W2. The double-sided adhesive tape S is affixed on the surfaces that are spaced apart from each other. In this case, the operator inspects the second winding body R2 to find the convex portion 91 where the maximum radius D is located on the outer peripheral surface, and a predetermined distance L from the convex portion 91 to the upstream side in the drawing direction of the web W2. The double-sided pressure-sensitive adhesive tape S is affixed to the surface separated by a distance, and the web W2 is further cut on the upstream side, and the ends of the web W2 are temporarily fixed with a plurality of tabs T.

  Therefore, as shown in FIG. 11, when the paper splicing device of the present embodiment is in a contact position where the web W1 is pressed against the outer peripheral surface of the second winding body R2 to perform the paper splicing, the air supply / discharge device 55 By actuating the cylinder 53, the paster arm 52 is rotated, and the paster roller 45 is moved to the pressing position for pressing against the outer peripheral surface of the second winding body R2 while supporting the web W1. At this time, the paster roller 45 reaches the double-sided adhesive tape S of the second winding body R2 before reaching the convex portion 91 while pressing the web W1 against the outer peripheral surface of the second winding body R2. The web W1 and the web W2 in the second winding body R2 are connected by the double-sided adhesive tape S, and the end of the web W2 of the second winding body R2 is pulled by the web W1, thereby cutting the tab from the cut. Then, the web W2 is pulled out from the second winding body R2, the web W1 and the web W2 travel together, and the web W1 is cut by the cutter 48, whereby the paper joining operation is completed.

  In this case, as shown by a two-dot chain line in FIG. 10, the paster roller 45 has the second winding body R2 while the web W1 is pressed against the outer peripheral surface of the second winding body R2 and reaches the convex portion 91. Therefore, the web W1 and the web W2 in the second winding body R2 can be appropriately connected by the double-sided pressure-sensitive adhesive tape S. Thereafter, when the paster roller 45 reaches the convex portion 91 of the second winding body R2, the paster roller 45 jumps away from the outer peripheral surface of the second winding body R2.

  Thus, in the paper splicing device of Example 5, when the convex portion 91 is formed at the position of the maximum radius D on the outer peripheral surface of the second winding body R2, the web W2 is drawn out from the convex portion 91. A double-sided adhesive tape S is affixed to a surface separated by a predetermined distance L on the upstream side in the direction.

  Therefore, since the paster roller 45 reaches the double-sided adhesive tape S of the second winding body R2 before reaching the convex portion 91 while pressing the web W1 against the outer peripheral surface of the second winding body R2, the web roller W1 The web W2 of the second winding body R2 can be connected by the double-sided adhesive tape S, and the web W1 from the first winding body R1 is appropriately pressed against the outer peripheral surface of the second winding body R2, thereby making the paper joint Work can be performed smoothly.

  The paper splicing device, the printing press, and the winder according to the present invention facilitate the paper splicing work by properly splicing the web, and can be applied to any printing press.
