  Next, the operation of the sheet feeding device K provided with the remaining sheet winding device 1 of the present invention will be described with reference to FIGS. 1, 2, 7 and 8 to 11. FIG.

  In the normal printing operation of the rotary press (not shown), the paper feeding device K stops the web support arm pair 6A, 6B at the position shown in FIG. 8, and the first web R1 supported by the web support arm pair 6A. Alternatively, the continuous paper is supplied from the second web R2 supported by the web support arm pair 6B.

  For example, a sensor (not shown) detects when the first web R1 supported by the web support arm pair 6A and having the continuous paper P1 drawn out has a predetermined first diameter, and the arm rotation shaft 5 is used for arm rotation. The motor 52 is rotated in the clockwise direction, and the web support arm pair 6A and the web support arm pair 6B are rotationally displaced, and are supported by the first web R1 and the web support arm pair 6B supported by the web support arm pair 6A. The second web R2 is also rotationally displaced.

  Due to this rotational displacement, the first web R1 moves to the position shown in FIG. 9, ie, the paper splicing position. When this movement is detected by a sensor (not shown), the arm rotation motor 52 stops, and the web support arm pair 6A, 6B stops at the position shown in FIG. When the first web R1 from which the continuous paper P1 supported by the web support arm pair 6A is pulled out at the paper splicing position reaches a predetermined second diameter, a sensor (not shown) detects this and waits. The second web R2 to be rotated is rotated counterclockwise by a driving device (not shown). The rotational peripheral speed of the second web R2 is accelerated until it reaches the same speed as the running speed of the continuous paper P1 that is drawn out from the first web R1 and travels. At this time, the paster arm 8 is displaced from the position of FIG. 9 to the position of FIG.

  Then, as shown in FIG. 10, when a sensor (not shown) detects that the first web R1 has reached a predetermined third diameter, the brush 80 is actuated at an appropriate timing to remove the continuous paper P1. Press against the circumferential surface of the second web R2. As a result, when the paper end Q of the second web R2 is stuck to the continuous paper P1 by the sticking portion, the temporary fixing is released and the paper is started to be pulled out together with the continuous paper P1. At substantially the same time as this operation, the cutter 81 acts on the upstream side of the splicing position of the continuous paper P1, the continuous paper P1 from the first web R1 is cut, and the rest becomes the remaining paper RS, and the spliced first paper The continuous paper P2 of the two roll paper R2 is pulled out and starts running.

  When the first web R1 is cut by the cutter 81, the rotation is stopped by the operation of a braking means (not shown) provided on the web support rotating shaft 62a, and the remaining paper RS in the state drawn out from the first web R1. Hangs down and the paster arm 8 returns to its original position and enters a standby state (FIG. 11).

  In FIG. 10, when the arm rotation motor 52 rotates, the arm rotation shaft 5 rotates counterclockwise, and when the arm rotation shaft 5 reaches a predetermined rotation phase, a sensor (not shown) detects it. The arm rotating motor 52 is stopped, the web support arm pair 6A and the web support arm pair 6B are rotationally displaced, and the first web R1 and the second web support arm pair 6B supported by the web support arm pair 6A are supported. The web R2 is also rotationally displaced and stops. This stopped position is a stop position during normal printing operation and is shown in FIG.

  As shown in FIG. 11, the stop position of the web support rotating shaft 62a of the web support arm pair 6A is such that the end surface 620 of the web support rotating shaft 62a protruding from the web support arm 60a is linked to the remaining paper wind device 1 of the present invention. This is a position facing the linkage portion 20 that is the circular end surface of the member 2. And the position of this 1st winding paper R1 is a remaining paper winding position, and the remaining paper winding of 1st winding paper R1 is performed by the remaining paper winding apparatus 1 in this position.

  Next, the operation of the remaining sheet winding device 1 of the present invention will be described with reference to FIGS. After the paper splicing is completed, when the first web R1 on which the drawn out residual paper RS hangs stops at the remaining paper winding position shown in FIG. 11, the air cylinder 41 of the moving means 4 shown in FIG. Expands. The linkage member 2 and the rotation driving means 3 attached to the substrate 40 by the extension of the cylinder rod 410 are moved toward the end surface of the winding support rotating shaft 62a supporting the first winding paper R1, and are shown in FIG. As described above, the linking portion 20 is pressed against the end surface 620 of the winding support rotating shaft 62a.

  When the linkage member 2 and the rotation driving means 3 are moved, the movement shaft 42 having the tip attached to the substrate 40 in common with the cylinder rod 410 moves in accordance with the movement guide 43. Assist and stabilize the straight movement of the means 3. At this time, the pressure input to the air cylinder 41 is adjusted and set in advance so that the pressing force by which the linking portion 20 of the linking member 2 presses the end surface 620 of the winding support rotation shaft 62a is appropriate.

  Next, the winding motor 30 is activated, and the rotation of the rotation shaft 300 causes the drive gear 31, the driven gear 32, and the linkage member rotation shaft 33 to rotate, and the linkage attached to the tip of the linkage member rotation shaft 33. The member 2 also rotates. With the rotation of the linkage member 2, the web support rotating shaft 62a whose end face 620 is pressed by the linkage portion 20 also rotates. This rotation direction is opposite to the direction in which the continuous paper P1 is rotated by the normal operation during printing, and is the clockwise direction in FIGS.

  At this time, the rotational speed of the web support rotating shaft 62a does not have to be the same as the rotational speed of the linkage member 2, and even if the contacting end surfaces slip, the web support rotating shaft 62a rotates and the remaining paper RS It is only necessary to be able to transmit the number of rotations that can be wound.

  The rotation of the winding motor 30 causes the winding paper support rotating shaft 62a and the winding paper R1 to rotate in the opposite direction to the rotation at the time of normal printing, and the remaining paper RS hanging down upstream from the cutting point at the time of paper joining is rewound. . The take-up motor 30 stops rotating when a timer that has been set in advance has a sufficient time sufficient to complete the rewinding of the remaining paper RS.

  After the rotation of the winding motor 30 is stopped, the cylinder rod 410 of the air cylinder 41 is shortened, and the linking part 20 of the linking member 2 is separated from the end surface 620 of the winding paper support rotating shaft 62a, and the linking member 2 and the rotation driving means are separated. 3 moves to a standby position (FIG. 3). Also in this movement, since the moving shaft 42 whose tip is attached to the substrate 40 in common with the cylinder rod 410 moves according to the moving guide 43, the linear movement of the linking member 2 and the rotation driving means 3 is assisted. Stabilize. Thereafter, the remaining core which is the first web R1 is removed from the web support rotary shafts 62a and 63a and collected. A new web R3 (not shown) is supported and mounted between the same web support rotating shafts 62a and 63a. The web R3 is located at the position of the web R2 shown in FIG. 8, and the operations of FIGS. 9, 10, and 11 are successively repeated a plurality of times as described above.

  FIG. 5 is an explanatory diagram when the paper roll R4 and the paper roll R5 to be used are narrower than the paper rolls R1 and R2. Even when the paper roll R4 and the paper roll R5 to be used are narrow, by providing a sufficient stroke amount of the cylinder rod 410 of the air cylinder 41 of the moving means 4, the linkage portion 20 of the linkage member 2 can be connected to the roll support shaft 62a. It is possible to press against the end surface 620 with an appropriate pressing force.

  When the linkage member 2 and the rotation drive means 3b move, the two movement shafts 42b and 42b move in accordance with the two movement guides 43b and 43b, respectively, so that the linkage member 2 and the rotation drive means 3b can be moved in a straight line. And stabilize. At this time, the pressure input to the air cylinder 41b is adjusted and set in advance so that the pressing force by which the linking portion 20 of the linking member 2 presses the end surface 620 of the winding support rotating shaft 62a is appropriate.

  Next, the winding motor 30b is activated, and the rotation of the rotation shaft 301 also rotates the linkage member 2 fixed to the rotation shaft 301 at the rotation center. With the rotation of the linkage member 2, the web support rotating shaft 62a whose end face 620 is pressed by the linkage portion 20 also rotates. This rotation direction is the reverse of the direction in which the continuous paper P1 is rotated by the normal operation during printing, and the remaining paper RS drawn from the web R is rewound.

  The above-described remaining paper winding device 1b according to the second embodiment of the present invention is more compact, can be easily maintained, can be manufactured at a low cost, and can easily cope with a change in the paper width of the winding paper as in the first embodiment. Is possible.

  Further, the moving means 4 of the remaining paper winding device 1 or the moving means 4b of the remaining paper winding device 1b according to the present invention may be constituted by a mechanism (not shown) including a rack and a pinion instead of the fluid pressure cylinder. . That is, the substrate 40 or 40b is attached to one end of the rack, and the pinion is attached to a pinion rotation driving means (not shown) to be engaged with the rack. Then, it is possible to reciprocate the rotation drive means 3 or 3b and the linkage member 2 by rotating the pinion by the rotation drive means and reciprocating the rack in the same direction as the expansion and contraction direction of the cylinder rod 410 by this rotation. .

  Further, the web paper support arm pair 6A, 6B when the remaining paper is taken up is stopped at a position 180 degrees apart from the normal printing operation stop position shown in FIG. It is preferable to provide the remaining paper winding device 1 or 1b so that the rotation can be transmitted to the remaining paper. However, as another example of the stop position of the web support arm pair 6A, 6B, at a position between the paper splicing position shown in FIG. 10 and the normal printing operation stop position shown in FIG. The stop position may be determined at a predetermined rotation phase, and the remaining paper may be wound in a state where the stop position is stopped.

  The present invention improves the number of parts compared to the prior art by improving the remaining paper winding device of the paper feeding device that continuously feeds the rolled paper in a printing device such as newspapers that are continuously printed in large quantities. Therefore, the printing efficiency is improved and the applicability in the printing industry is high.
