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.

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 continuous 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 or during the feeding process, the feed motor 21
rotates the feed screw 20 to remove the side plate 13 on the movable side.
In order to reciprocate several times in the direction of the side plate 12 on the reference side, the continuous paper 9 is pushed by the side plate 13, 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
is detected, and the carry-in conveyor 11, belt conveyor 73, and belt conveyor 107 operate in the feeding direction. In this way, the lowest 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 backwards, which is detected by the sensor 66 in front of the vacuum nozzles 69, 70, and under predetermined conditions, the tail end 9b of the continuous paper 9 falls backward. 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 extrusion member 106 moves the stacked continuous paper 9 to the lifter side plate 32a on the reference side. Press it in a biased state by reciprocating several times in the direction of . 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 automatic connection and feeding device 1, as shown in FIG.

Tip drawing process Next, the reducer/drive motor 35 is automatically started, the lifter 2 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, arm portion 4
8 and the splice part 82 are rotated by the respective vertical movement motors 41 and 85, and are slightly lowered and stopped at a height that allows continuous paper 9 to be placed above the middle continuous sheet 9 without hitting the upper hopper device. do. 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 opposite direction. Note that when the slide member 42 moves, the distal end puller device 4 and the splicing device 6 provided thereon are also moving at the same time. Due to this movement of the arm section 48, the upper end portion of the middle continuous sheet 9 in the feeding direction comes into contact with the reference surface 52a of the swing arm 52, 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 distal end portion 9a and the tail end portion 9b in the aligned state are pressed down by the presser plate 63, and the positioning state is achieved. In this pressed state, the splice portion 82 automatically stops descending.

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

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 operation 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.

The tapered pins 60 and 61 are not limited to conical shapes.
It may have other shapes as long as it is tapered, and the direction in which it protrudes is not limited to downward from above, but may also be made to protrude upward 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. Furthermore, in order to prevent more than one sheet from being drawn 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.

Effects of the Invention In the present invention, since the reference surface accurately regulates the position of the tip during suction, the positioning of the tip can be reliably regulated within a necessary tolerance during suction and subsequent guidance. Also, before the vacuum patch hits the top surface of continuous paper, the sensor detects its approach and stops the arm body from descending.
When the vacuum pad is pressed in, that is, when moving in the backward direction, the top surface of the continuous paper is not disturbed and remains aligned during the feeding process, so that alignment can be ensured in each subsequent process.

Further, as in the embodiment, if the swing arm has a swinging function and a blow nozzle has a jetting function, only one sheet of continuous paper can be reliably pulled out. Furthermore, if the vacuum pad is supported in a floating state, control of the amount of vertical movement of the arm body can be simplified. Further, in an embodiment in which the arm main body and the splice portion are commonly supported by the slide member, the horizontal movement movement can be shared, so that the drive means for them becomes structurally simple.
