OBJECT OF THE INVENTION Therefore, an object of the present invention is to properly regulate the ends of the front and rear continuous sheets at the butting position when automatically connecting the front and rear continuous sheets during the replenishment process of this type of continuous paper. This makes it possible to commonly use continuous paper of other sizes.

Solution to the Invention Therefore, in the process of connecting continuous paper, the present invention focuses on the sprocket holes at both ends of the continuous paper, and inserts two tapered pins into the sprocket holes straddling each end. As a result, the connection position in the feeding direction and the width direction of the continuous paper are correctly regulated at the butting position, thereby making it possible to connect the continuous paper in almost the same state as in the middle of the paper.

The belt conveyor 107 is made of an endless belt made of fluororesin with a small coefficient of friction, and is wound around a roller 120 over a wider area than the width of the continuous paper 9. It is adapted to move on the surface of the belt guide 122 on the upper surface side thereof. Note that the tension of this belt conveyor 107 is adjusted by the position of a tension roller 121 provided in the middle. The roller 120 is supported by the lifter side plates 32a and 32b by two shafts 123, and is supported by a conveyor motor 124 and a timing belt/pulley 125 wound around them.

Further, this belt conveyor 107 is connected to an electromagnetic brake 126 at one end of its shaft 123 so that it can be stopped immediately after the conveyance operation. Note that this electromagnetic brake 126 is attached to the upper surface of the lifter 32 by a bracket 127.

In addition, as shown in FIG. 21, an auxiliary conveyor 128 is provided on the feeding direction side of this belt conveyor 107, and a drive motor 129 and a belt conveyor 128 are provided.
The conveyor 107 is driven by a pulley 130 at a faster speed than the conveyor 107.

Incidentally, the above-mentioned apparatus is sequentially controlled by a sequence type control device 132 while checking the operation of each process. This control device 132
is installed at an appropriate position on the frame 8, detects the movement of each part using a limit switch and the aforementioned sensor group, and drives a motor etc. as an operating section.

Effects of the Invention As already mentioned, the continuous paper 9 is folded in a zigzag shape and stored in the case. It should be noted that the following description will proceed on the assumption that the automatic connection and supply device 1 does not have any continuous paper 9 at all.

Preparation Work First, a worker confirms the size of the continuous paper 9 and inputs data corresponding to the size into the control device 132. As a result, the hopper device 2, the tip puller device (4), the connection positioning device 5
The biasing device 7 and the like move the movable members to predetermined positions, and set the necessary vacuum parts 49, vacuum nozzles 70, etc. to operable states according to their sizes.

Supply work In this state, the worker takes out the continuous paper 9 from the storage case etc., opens the guide 10, and places the bottom continuous paper 9 on the guide 10 with only one sheet hanging down. Push in the feed direction. At this time, the insertion sensor 25 detects the presence of the continuous paper 9, starts the drive motor 24, and moves the carry-in conveyor 11 in the feeding direction of the arrow, thereby moving the continuous paper 9 toward the back. let During this movement, the fixed position sensor 26
detects the movement of the continuous paper 9 and transfers it to the carry-in conveyor 11.
stop immediately.

At this time, the leading edge side corner of the continuous paper 9 in the feeding direction comes into contact with the vertical stopper 29 and stops. Also, during this time, during the feeding process, the feed motor 21 rotates the feed screw 20 to reciprocate the movable side plate 13 several times in the direction of the reference side side plate 12. , it comes into contact with the side plate 12 on the reference side and is in a positioning state. Thereafter, when the worker closes the guide 10 in the open state, the tail end 9b of the continuous paper 9 after being carried in is in contact with the rear end surface of the stacked continuous paper 9 together with the guide 10 inside the hopper device 2. is stored in

In this way, the continuous sheets 9 are sequentially fed into the three-stage hopper device 2 as shown in FIG. Thereafter, the vertical stopper 29 is moved back by the drive cylinder 31 by the operation of the worker.
The continuous paper 9 becomes movable in the feeding direction.

Feeding process When the continuous paper 9 enters the bottom hopper device 2 in a positioned state, the position sensor 26
The input conveyor 11, belt conveyor 73, and belt conveyor 107 operate in the feeding direction. In this way, the bottom row of continuous paper 9
rides on them and is automatically sent to the top of the belt conveyor 107. In the process, the tail end 9b of the continuous paper 9 falls backward, and is detected by the sensor 66 in front of the vacuum nozzles 69, 70, and is detected by the conveyor 11, the belt conveyor 73, and the belt under predetermined conditions. conveyor 1
07 all stop. At this time, the tail end portion 9b is stopped on the center line in the width direction of the fixed guide 62, that is, at a substantially fixed position.

Offsetting process During or after the continuous paper 9 moves to the belt conveyor 107 of the offsetting device 7, the motor 117 operates, and the pressing member 106 moves the stacked continuous paper 9 onto the lifter side plate on the reference side. It is pressed in the direction of 32a in a biased state by reciprocating several times. As a result, the continuous paper 9 slides on the belt conveyor 107 while remaining on the guide plate 111 with one side, and enters the positioning state. Note that when the belt conveyor 107 stops, the electromagnetic brake 126 immediately operates, so that the tail end portion 9b is correctly positioned on the fixed guide 62. In this way, the lowest continuous sheet 9 is first fed into the automatically connected and fed sheet 1, as shown in FIG.

Tip drawing process Next, the reducer/drive motor 35 is automatically started, the lifter 32 is raised by the feed nut 33 and the feed screw 34, and automatically stops at the middle height of the continuous paper 9 in the middle tier. do. At this time, the arm portion 48 and the splice portion 82 are rotated by the respective vertical movement motors 41 and 85, and are slightly lowered so that the continuous paper 9 in the middle tier can be inserted above the continuous paper 9 without hitting the hopper device in the upper tier. Stop at height. Thereafter, the large cylinder 44 operates and the slide member 42 moves in the opposite direction to the feeding direction, so that the vacuum pad 49 of the arm portion 48 faces onto the continuous paper 9 in the middle stage.

Next, the arm section 48 descends, and when the sensor 48a of the arm section 48 detects the upper surface of the middle continuous sheet 9, the arm section 48 automatically stops descending. Thereafter, the small cylinder 46 operates to further horizontally move the slide member 42 in the direction opposite to the feeding direction. Note that when the slide member 42 moves, the tip pull-out device 4 provided thereon
and the splicing device 6 are also moving at the same time.
By this movement of the arm portion 48, the upper end portion of the middle continuous sheet 9 in the feeding direction is moved to the swing arm 52.
It hits the reference surface 52a of , and is pushed in a little for reliable positioning.

The arm portion 48 descends again, and the vacuum pad 49 adsorbs the topmost continuous sheet 9 and ascends. This suction portion corresponds to a portion that is slightly elevated by the inclined guide plate 23 of the hopper device 2. During this ascent, the swing arm 52
is driven by the cylinder 58, and in the process, the blow nozzle 53 blows air onto the end surface of the continuous paper 9 on the feeding side, thereby preventing the vacuum pad 49 from suctioning a plurality of sheets.

Thereafter, the arm portion 48 is moved horizontally in the feeding direction by the large cylinder 44 and the small cylinder 46,
Next, along the guide bar 37, the feed screw 38 and the vertical movement motor 41 are used to lower the leading end 9a of the continuous paper 9 being sucked, as shown in FIG. guide onto the guide 62. At this time, the vacuum nozzles 69, 70
Since negative pressure air is introduced into the continuous paper 9, the leading end 9a of the continuous paper 9 in the middle stage and the tail end 9b of the continuous paper 9 fed in first are brought into contact with each other and placed on the fixed guide 62. Thereafter, the suction of the vacuum pad 49 is released, and the arm portion 48 rises to its original position with the tip portion 9a placed on the fixed guide 62. At this time, swing arm 52
also returns to its original position.

Next, the large cylinder 44 and the small cylinder 46 move the connecting positioning device 5 and the splicing device 6 in the opposite direction to the feeding direction, and the movable body 64 for taping moves above the connecting portion of the continuous paper 9. Located in

After that, the two tapered pins 61 on the movable side are projected downward by the driving cylinder 67, and then
The splice portion 82 is lowered by the vertical movement motor 85. During this downward movement, the tapered pin 60 on the lower surface side of the presser plate 63 and the tapered pin 61 on the movable side in the protruding state move into the sprocket holes 9c formed on both side edges of the continuous paper 9, as shown in FIG. The tip portion 9a and the tail portion 9b are accurately positioned. At this time, even if the leading and trailing continuous sheets 9 are deviated within a tolerance range equal to the radius of the cone of the tapered pins 60 and 61, they are corrected to the correct position in the process of fitting into the tapered pins 60 and 61. That is, since the pins 60 and 61 have the same thickness as the sprocket hole 9c, they are automatically corrected when lowering.

Thereafter, the tip end 9a and the tail end 9b in the aligned state are pressed down by the presser plate 63, and the positioning state is achieved. In this holding plate state, the lowering of the splice portion 82 is automatically stopped.

Splicing process Next, the tapered pin 61 on the movable side is raised, and the movable body 64 is moved slightly to the left in FIG. 14, stopped at the end of the continuous paper 9, and then is moved by the feed motor 79 in the direction of the side plate 32a (to the left in FIG. 14).

During this movement, the tape feeding motor 101 rotates the drive roller 92 in the feeding direction, so that the tape 87 is guided by the tape guide 94 as shown in FIG. Then, they are sequentially applied while straddling the abutting surfaces of the tail end portions 9b. Thereafter, the heater 96 heats the tape 87 to attach it to the abutting surfaces. Shortly before the end of this taping, when the cutter 95 faces the ends of the tip end 9a and the tail end 9b, it is pushed out by the operating cylinder 97 and cuts the tape 87. Even after this cutting, the movable body 64 moves, so the tape 87
The leading end 9a and the trailing end 9b of the continuous paper 9 are spliced along the entire width in the mating direction to the end in a state where they are completely mated. At this time, the punch unit 105 automatically operates to punch a mark at the abutting portion. After this process, the splice portion 82 rises and the joining process is completed.

Thereafter, arm portion 48 and splice portion 82
is horizontally moved in the feeding direction by the large cylinder 44 and the small cylinder 46, and then the lifter 32 is lowered, and the middle belt conveyor 11 and the belt conveyor 73 are in a continuous state at the same height. At this time, both the arm portion 48 and the splice portion 82 rise to their original positions.

Subsequently, all the carry-in conveyors 11, the belt conveyor 73, the belt conveyor 107, and the auxiliary conveyor 128 are driven in the feeding direction, so that the preceding continuous paper 9 is fed from the belt conveyor 107 to the next auxiliary conveyor 128. Furthermore, the continuous paper 9 in the middle stage is transported to the belt conveyor 107 of the shifting device 7.
It is fed to the position and stops after the shifting process in the same way as above. Note that since the feeding speed of the auxiliary conveyor 128 is faster than that of the other conveyors, the food is fed to the predetermined supply position quickly.

The continuous paper 9 on this auxiliary conveyor 128 is guided to a printing device or the like, and is drawn in sequentially as the printing progresses. Each time the continuous paper 9 on the auxiliary conveyor 128 runs out, the series of operations is repeated, and the continuous paper 9 is replenished at a predetermined supply position in a connected state. Therefore, if new continuous paper 9 is replenished into the hopper device 2 before all of the continuous paper 9 at the supply position is consumed, the replenishment interval for continuous paper 9 becomes longer, and this replenishment operation becomes more difficult for the printing device. This means that it can be done easily without being affected by consumption speed.

Modification of the invention The tapered pins 60, 61 are not limited to conical shapes,
It may have any other shape as long as it is tapered, and its protrusion direction is not limited to downward from above, but may be upwardly protruded from the fixed guide 62 portion. Further, the shifting operation may be performed during the feeding operation of the continuous paper 9, or may be performed while the continuous paper 9 is stopped as described above.

Furthermore, if the belt conveyor 107 is made of a material with low frictional resistance and is used in one piece, or in combination with a plurality of pieces with no steps in the width direction, it is possible to shift the lifter side plate 32a to one side in the direction of the reference surface. It can be done with relatively light force.

Furthermore, the means for moving the slide member 42 in the feeding direction or in the opposite direction may be configured by a feed screw unit instead of the large cylinder 44 and the small cylinder 46. Further, in order to prevent more than one sheet from being pulled out, the blow nozzle 53 is provided in the above embodiment, but such a function can also be realized by a simple blowing action of the swing arm 52.

Effect of the invention The present invention provides the following unique effects.

In the process of loading, aligning, and connecting continuous paper, accurate positioning and fixing of continuous paper after alignment are performed in an orderly manner, and the continuous paper is securely fixed and positioned. It becomes possible to automate work.

Two of the four tapered pins are movable, so it can flexibly handle continuous paper of various sizes.Furthermore, the two movable pins are provided so that they can be moved forward and backward using the advance and retreat means, so it is easy to set the size. By setting the pins on the movable side in a relaxed state, the size can be easily set in a wide space regardless of the presence of the two tapered pins on the movable side.

When the tapered pins advance, the four tapered pins fit into the sprocket holes of the two continuous papers to be connected, accurately positioning them, and in the positioned state, hold down the continuous paper to be connected with the press plate and fix it. Therefore, the tapered pin on the movable side is released, a splice is made, and the movable body can move in the paper width direction.This allows the tapered pin to move in the paper width direction and the splice unit to move in the paper width direction. The drive source can be used for both purposes, and the configuration of the movable parts can be simplified.
