Abstract

PURPOSE:To utilize a device for the positioning of continuous sheets of other sizes by displacing two of four tapered pins provided at positions corresponding to sprocket holes on both sides of the butt joint section of continuous sheets in response to the sizes of the continuous sheets. CONSTITUTION:Two tapered pins 61 on the movable side are protruded downward by a cylinder 67, and a splice section 82 is lowered. During this descent, a tapered pin (on the reference plane side) on the lower side of a presser plate 63 and a protruded pin 61 on the movable side are inserted into sprocket holes on both side edges of a sheet, and the rear end section of the preceding sheet and the front end section of the succeeding sheet are correctly positioned. In this case, even if the continuous sheet is displaced within tolerance equal to the radium of the tapered pin, it is corrected to a correct position while it is being engaged with pins. Accordingly, continuous sheets of many sizes can be positioned by fitting a tapered pin on one side to a member at the fixed position on the reference side and fitting a tapered pin on the other side to a member displaced in response to sizes of sheets.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for automatically connecting and feeding the ends of zigzag-folded continuous sheets of paper, and in particular to a device for automatically connecting and feeding the ends of continuous sheets of paper that are to be interconnected. It concerns a device for precisely positioning the ends of each other in a connecting position with respect to each other.

BACKGROUND OF THE INVENTION Continuous paper is used for data output from computers and the like. This continuous paper is folded in a zigzag shape and is housed inside the case.

is attached to the top of the

In addition, on the feeding direction side of this belt conveyor 107, there is a second
As shown in Figure 1, an auxiliary conveyor 128 is provided,
It is driven by a drive motor 129 and a belt pulley 130 at a faster speed than the conveyor 107. Further, a connecting conveyor 119 is provided as necessary between the hopper device 2 and the belt conveyor 73 of the connecting positioning device 5, and drives the continuous paper 9 in the feeding direction when necessary.

By the way, the above device is a sequence type control device 131.
The system is controlled sequentially while checking the operation of each process. This control device 131 is installed at an appropriate position on the frame 8, detects the movement of each part using limit switches and the aforementioned sensor group, and drives a motor etc. as an operating part.

Effects of the Invention As already mentioned, the continuous paper 9 is folded in a zigzag shape and stored in a size that can be 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 shifting device 7, etc. move the movable member to a predetermined position, and also set the necessary vacuum butt 49, vacuum nozzle 70, etc. in an operable state according to the size.

Feeding operation In this state, the operator takes out the continuous paper 9 from the storage case, etc., opens the guide 10, places the continuous paper 9 on the lower layer on the guide 10 with only one sheet hanging down, and feeds the continuous paper 9. push in the direction. At this time, the insertion sensor 25 detects the presence of the continuous paper 9, and the drive motor 2
4 is activated and the carry-in conveyor 11 is moved in the feeding direction of the arrow, thereby moving the continuous paper 9 toward the back. During this movement, the fixed position sensor 26 detects the movement of the continuous paper 9 and immediately stops the carry-in conveyor 11.

At this time, the continuous paper 9 stops with the leading edge side corner in the feeding direction hitting the vertical stopper 29. Also, during this time or 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. After that, 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 attached to the guide 10.
The continuous paper sheets 9 are stored in the hopper device 2 in contact with the rear end surface of the stacked continuous paper sheets 9 along with the paper sheets 9.

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 backward by the drive cylinder 31 by the operator's operation, and the continuous paper 9 becomes movable in the feeding direction.

In the feeding process, when the continuous paper 9 enters the hopper device 2 at the bottom in a positioned state, the position is detected by the fixed position sensor 26, and the connecting conveyor 131, belt conveyor 73, and belt conveyor 107 operate in the feeding direction. In this way, the continuous paper 9 at the bottom row is placed on top of them and is automatically fed to the top of the belt conveyor 107. In the process, the tail end 9b of the continuous paper 9 falls backwards, and is detected by the sensor 66 in front of the vacuum nozzle 69,700. 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 is moved to the belt conveyor 107 of the offsetting device 7, the motor 11
7 is operated, and the pressing member 106 presses the stacked continuous sheets 9 toward the reference side lid one side plate 32a by reciprocating several times in a biased state. 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 this belt conveyor 107 stops,
Since the electromagnetic brake 126 operates immediately, the tail end 9
b is correctly positioned on the fixed guide 62. In this way, even lower! Paper 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 32 is raised by the feed nut 33 and the feed screw 34, and automatically stops at the middle of the continuous paper 9 in the middle row. . At this time, the arm portion 48 and the splice portion 8
2 is rotated by the respective vertical movement motors 41 and 85, and is slightly lowered, and stops at a height such that it can be inserted above the continuous paper 9 in the middle tier without hitting the guide 10 in the upper tier. 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 above 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 the slide member 42
When is moving, the tip pulling device 4 and the splicing device 6 provided thereon are also moving at the same time.

By this movement of the arm section 48, the upper end portion of the middle continuous sheet 9 in the feeding direction is aligned with the reference surface 52 of the swing arm 52.
a, and is pushed in a little to ensure accurate positioning.

The arm portion 48 descends again, and the vacuum butt 49 suctions 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 upward movement, the swing arm 52 moves towards the cylinder 5.
8, but in the process the blow nozzle 53
The air is blown 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 horizontally moved in the feeding direction by the large cylinder 44 and the small cylinder 46, and then moved along the guide bar 37 by the feed screw 38 and the vertical movement motor 41.
The leading edge 9 of one sheet of continuous paper 9 that is being sucked is lowered by
a onto the fixed guide 62 of the connection positioning device 5, as shown in FIG. At this time, the vacuum nozzle 69
．． Since the negative pressure air is guided to 70, the leading end 9a of the continuous paper 9 in the middle stage and the tail end 9b of the continuous paper 90 fed first are ? It is placed on the fixing guide and drawer 2 in the aligned state. Thereafter, the suction of the vacuum butt 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, the swing arm 52 also returns to its original position.

In the positioning process, the large cylinder 44 and the small cylinder 46 then
The connection positioning device 5 and the splicing device 6 move in the opposite direction to the feeding direction, and the movable body 64 for taping is positioned above the connection portion of the continuous paper 9.

After that, the two tapered pins 61 on the movable side are made to protrude downward by the driving cylinder 67, and then the splice part 8
2 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 protruding movable side are inserted 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 pin 60.61, they are corrected to the correct position in the process of fitting into the tapered pin 60.61.

After that, the tip end 9a and the tail end 9b in the aligned state
is pressed down by the temporary presser foot 63, and is in a positioning state. In this pressed state, the splice portion 82 automatically stops descending.

Splicing process Next, the tapered pin 61 on the movable side is raised, and then the movable body 64 is moved. It is moved in the direction of the side plate 13 of the DI, stopped at the end of the continuous paper 9, and then moved in the direction of the side plate 12 on the reference side by the feed motor 79.

During this movement process, the tape feeding motor 101 rotates the drive roller 92 in the feeding direction, so the tape 8
7 is guided by a tape guide 94 as shown in FIG.
It is applied one after another while straddling the abutting surfaces. Thereafter, the heater 96 heats the tape 87 to attach it to the mating 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. Since the movable body 64 continues to move even after this cutting,
The tape 87 is attached to the leading end 9a and the trailing end 9 of the continuous paper 9.
b are joined together in a state of complete abutting along the entire width in the abutting direction up to the end. 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.

After that, the arm part 48 and the splice part 82 are moved horizontally in the feeding direction by the large cylinder 44 and the small cylinder 46, and then the lifter 32 is lowered, so that the middle belt conveyor 18 and the connecting conveyor 131 are at the same height. becomes a continuous state. At this time, both the arm portion 48 and the splice portion 82 rise to their original positions.

Next, all loading conveyors 11 and belt conveyors 7
3. Since the belt conveyor 107, the auxiliary conveyor 128, and the connecting conveyor 131 are driven in the feeding direction, the preceding continuous sheet 9 is fed from the belt conveyor 107 to the next auxiliary conveyor 128. Also, continuous paper 9 in the middle row
is fed to the position of the belt conveyor 107 of the shifting device 7, and stops after the shifting process in the same way as described 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 the hopper device 2 is replenished with new continuous paper 9 before all of the continuous paper 9 at the supply position is consumed, the replenishment interval of continuous paper 9 becomes longer, and this replenishment operation increases the consumption rate of the printing device. This means that you can do it easily without being affected by it.

Modifications of the Invention The tapered pins 60, 61 are not limited to conical shapes, but may have other shapes as long as they are tapered, and the protruding direction thereof is as follows:
It is not limited to the downward direction from above, but may be made to project upward from the fixed guide 62 portion. In addition, the one-sided shifting operation is
This 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.

Further, the means for moving the slide member 42 in the feeding direction or the opposite direction does not depend on the large cylinder 44 or the small cylinder 46;
It can also be configured with a feed unit. Furthermore, 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.

Effects of the Invention In the present invention, four tapered pins are fitted into the sprocket holes of the continuous paper, making it possible to easily and accurately position the paper. Furthermore, since two of the tapered pins are movable, it is possible to handle continuous paper of various sizes.

In addition, if the tapered pin on the movable side is provided in a part of the taping unit as in the embodiment, a dedicated moving means for the tapered pin is not required. However, if the holding plate of the splice part is provided with a tapered pin on the fixed side, positioning and holding can be performed automatically by lowering the pin.
