DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention places paper loaded on a horizontal lift table or the like on an inclined lifting table of a paper aligning machine in order to stack the paper with the paper edges aligned. The present invention relates to a paper transport device for a paper aligning machine that transports onto a placed pallet.

[Conventional technology]

The sheet feeding device of the sheet-fed printing press is provided with a paper loading platform for loading printing paper, and the loaded sheets are sucked one by one from the upper layer by the stacking device and delivered to the differential plate. After that, it is supplied to the printing unit for printing. In this case, the paper supplied to the paper stack is conveyed to the paper feeding position by a lift or the like in a state where it is highly stacked on the pallet at another place and is supplied, but the end of the paper stacked on the pallet is supplied. If the sheets are not aligned, the printing register is misaligned and a waste sheet is generated. Therefore, a sheet aligning machine that stacks the sheets while aligning the edges of the sheets is provided at a place where the sheets are stacked high on the pallet.

In an automated printing work system that has been developed in recent years, paper alignment and reversal stations are incorporated in the system, and paper stored in a warehouse, for example, several hundred sheets each, is stored on a conveyor. Is transported to the lift table of the above, and is supplied and aligned while unwrapping the packages on the pallet which is supplied from the lift table to the paper aligning machine in advance. In addition, when printing on the back side of the paper printed with the printing unit, after printing, the paper stacked on the paper stack of the paper discharge device is conveyed to the above station with the conveyor as it is in the pallet, and the paper is aligned in the paper aligner. After reversing it with the reversing machine attached to it, the paper is fed from the lift table to the paper aligning machine to perform paper alignment.

Therefore, an outline of the paper aligning machine will be described with reference to FIGS. 13 and 14. FIG. 13 is a schematic perspective view showing this paper aligning machine in a state where a pallet is supplied, and FIG. 14 is a schematic perspective view showing a state in which papers are similarly loaded on the pallet. In the figure, an L-shaped base 1 is also provided with a L-shaped frame body 2 in a plan view, and an elevating table 3 that is driven by a drive device (not shown) to ascend and descend is provided in the frame body 2. It is provided. The above-mentioned lift table has one side 2a of the frame body 2
Is arranged with the center line of the table substantially positioned on the vertical bisector. The frame body 2 is rotatably supported at the lower end portion thereof, and the position where the elevating table 3 shown in FIG. 13 is in a horizontal state and from this state, the tips 2c of the two sides 2a and 2b,
2d is raised by the same amount, and is rotated between the elevation table 3 shown in FIG.

In the paper aligning machine 4 configured in this way, the pallet 5 is supplied from the lift table onto the horizontal elevating table 3 shown in FIG. 13 along the direction of the arrow orthogonal to the side 2a, and after the supply, the frame The body 2 is tilted as shown in FIG. The paper conveyed to the lift table during this period is supplied onto the pallet 5 by a predetermined number and is stacked as indicated by reference numeral 6, and the elevating table 3 descends according to the stacking amount of the paper 6. During such stacking, the paper 6 slides on the slanting pallet 5 so that the paper edge contacts the inner surface of the frame body 2, and a vibrating plate (not shown) provided on the frame body 2 side with respect to the paper edge. By reciprocating and giving vibration, the paper edges can be aligned. After the stacking, the frame body 2 is brought into a horizontal state again and the stacked paper sheets are taken out onto the lift table in the form of pallets.

By the way, development of a paper conveying device for a paper aligning machine is being attempted in order to incorporate such a paper aligning machine in the above-described automation process of the printing work. This paper transport device reciprocates the paper gripper between the lift table and the paper aligner, and transports the paper held by the paper gripper from the lift table to the lifting table of the paper aligner. To do.

[Problems to be solved by the invention]

However, in such a paper transport device, when the paper gripping tool holds the paper on the lift table,
If you do not hold the paper by holding it so that the gripping edge of the paper is at right angles to the conveying direction, the paper may interfere with the frame or be skewed when stacked, causing the paper to tear or the paper alignment to be poor. To do. And the distortion of this paper generally occurs because one end of the paper is clamped before the other end, and this does not fix even if the other end is clamped, so both ends must be clamped at the same time. However, the workability is extremely poor and skill is required, which has been an obstacle to the practical use of the paper conveying device.

[Means for solving problems]

In order to solve such a problem, in the present invention, a paper gripping tool that grips and conveys paper is provided with a pair of fixed disks supported on the traveling arm side, and a pair of fixed disks facing each fixed disk and vertically moved to the traveling arm side. The movable disk is movably supported and a driving means for the movable disk, and the fixed disk and the movable disk are rotatably supported around an axis perpendicular to the plane of the drawing.

[Action]

With this configuration, the paper loaded on the horizontal plane is lifted and held separately between the upper and lower discs on one side and between the upper and lower discs on the other side. Even if you have cancer, you can correct the distortion by rotating the previous disk when holding it on another disk.

It is fixedly supported via 104. On the opposite side of the rail 74 to the groove cam 103, the other cam is provided in parallel with the groove cam 103 and the rail 74. That is, three types of cam bases 105, 106, 107 of high and low are fixed and erected by bolts 108 at three positions on the frame 16. A plate-shaped cam 109, which is similar to the cam plate 99 in a side view, is fixedly supported via a support fitting 110. The plate cam 109 is provided with a paper gripping operation which will be described later.
The height of the starting end on the side of the cam base 105 is the groove.
It is considerably lower than the height of the starting end on the 5th side, and the inclination from the starting end to the V-shaped bent portion is steeper than that on the groove cam 103 side. This is shown in FIG. 6 by showing the groove cam 103 and the plate cam 109 in a disassembled state into a starting end portion and a terminating end portion, respectively, and showing the cam base 105 considerably lower than the cam base 95. ing. Then, the rollers 93 and 94 are engaged with the cams 103 and 109 on both sides configured as described above, respectively. In this case, the roller 94 on the plate cam 109 side is constantly pressed against the plate cam 109 by the weight of a paper gripping tool or the like, which will be described later, fixed to the arm shaft 88, and the roller 93 on the groove cam 103 side is on the upper side of the groove cam 103. It is pressed against the cam plate 98. Therefore, the cam plate 99 on the lower side of the groove cam 103 plays a role of restricting the roller arm 90 from largely swinging.

As described above, the arm shaft 88, which is integrated with the roller arm 90 that can be raised and lowered and rotated, has a projecting end portion formed in a U shape as shown in FIG. A square bar-shaped arm 111 as a gripper holding member extending in a direction orthogonal to the axis 88 is fixed by a bolt 112.

By doing so, it is configured to be compatible with the paper size.

The operations of the paper aligning machine and the paper transporting device configured as described above will be described. The frame 42 of the paper aligning machine 11 is placed upright so that the lifting table 49 is horizontal, and the pallet 5 is placed on the descending lifting table 49 from the lift table 123 side.
Supply 0. At this time, as the pallet 50, a pallet corresponding to a paper size is used, and the pallet 50 is inserted from the square hole provided in the cover 41.
2 Leave it outside. Then, the motor 28 is started to rotate the elevating drive shafts 29 and 33, and the chains 46 and 4
After elevating the elevating table 49 to the ascending limit position via 7, 48, when the motor 24 is started, the pinion 25
The prism 20 descends due to the engagement of the rack 26 with the rack 26,
The whole 2 tilts. In this case, the prism 2 with the rollers on both sides of the brackets 18 on the diagonal line in FIG.
Since the frame 42 inclines so that 0 descends,
Symbols A, B, C, D as shown in the figures on each corner of the pallet 50
If a mark is added, points A and C do not move in the vertical direction, point D descends, and point B rises. When this is seen from the lift table 123 side in FIG. 10, the right side is lowered and the left side is raised. Also, when viewed from the side of the paper transporting apparatus in FIG. 1, the pallet 50 is facing rightward, that is, the lift table 12
The front side on the side far from 3 descends, and the rear side on the side close to the lift table 123 rises. In the following description, the paper aligning machine 11, the lifting table 49, the pallet 50, and the paper 5 will be referred to by the reference numerals attached to the respective corners of the pallet 50 in FIG.
The corners such as 1 are called A side, B side, C side, and D side.

On the lift table 123 which has finished supplying the pallet 50, the paper 51 is conveyed from the warehouse by the conveyor and loaded. In this case, as for the paper 51, which is packed in a predetermined number of sheets in the warehouse, the seal part of the package is cut during transportation, and several packages are stacked on the lift table 123 in a state of only being covered with the wrapping paper. . The operator stands facing the lift table 123 at a position near the A side of the paper aligning machine 11 and
The paper 51 for each package is placed on the upper and lower discs 121 of the paper transport device 60,
Perform the work of holding between 122. At the start of the work, the disks 121 and 122 held by the arm 111 are in a position slightly protruding from the paper aligning machine 11 to the lift table 123 side as shown by the chain line in FIG. At this time, the rollers 93 and 94 for the cams 103 and 109 are at the lower positions which are the starting ends of the cams 103 and 109, and are descending on the lifting guide shaft 83 to the arm bearing 87, and as shown in FIG. In the section, the cam base 105 is considerably lower than the cam base 95, so that the roller arm 90 rotates counterclockwise in FIG. As a result, if the cam bases 103 and 109 are at the same height, the roller arm 90, which should be inclined according to the inclination of the frame 42, is in a horizontal state without being inclined. That is, the inclination of the frame 16 and the inclination of the roller arm 90 in the opposite direction are offset to each other, and the arm 111 coaxial with the roller arm 90 is in a horizontal posture, so that the discs 121 and 122 on one side and the discs 121 and 1 on the other side.
22 is flush with paper 51. The height of the disc 122 at this time is B on the rising side of the lifting table 49.
Side and the height of the paper 51 on the lift table 103 are almost the same, and the height is lower than the C side which is the non-elevating side of the elevating table 49.

Therefore, the operator opens the wrapping paper of the uppermost paper 51 and holds two front ends of the paper 51 for one wrapping.
I'll insert it between two. The inserted paper edge is the limit switch 1
When the contacts of 25 are closed, the air cylinder 115 operates and the upper disk 121 descends, so that the paper 51 is connected to the lower disk 122.
Hold on to. In this case, even if the paper 51 may be distorted by holding the paper 51 between the discs 121 and 122 on one side first and holding the paper 51 to the discs 121 and 122 on the other side a little later than this. , The discs 121 and 122 are rotatably formed, so that the paper 51 that is distorted by holding one of the discs 121 and 122 in the other disc 121,122 is distorted.
The distortion is corrected by the rotation of the disks 121 and 122 when the paper 51 is held, and the paper 51 is correctly held. Then, when the pedal 62 is rotated to rotate the motor 62, the chain 73 travels, and the traveling platform 76 travels along the rail 74 via the eccentric plate 79, whereby the arm 111 causes the rollers 93, 9 to move.
4 is engaged with the cams 104 and 107 on both sides to run. The running locus of the trailing edge of the paper 51 at this time follows the side view shape of the groove cam 103 shown in FIG. 1 and the height difference between the left and right cams 104, 107. That is, when the frame 16 is tilted from the state shown in FIG. 1, the groove cam 103 is substantially horizontal from the starting end to the bent portion and has a downward slope from the bent portion to the trailing end. Further, the other cam 109 has almost the same downward slope from the bent portion to the end as the grooved cam 103, but has an upward slope from the start end to the bent portion. As a result, the gripping edge of the paper 51 changes from the horizontal posture to the inclined posture before reaching the elevating table 49, and after reaching the elevating table 49, it is parallel to the upper surface thereof and faces a position slightly higher than this toward the end. Drive downhill. The link pin 82 connecting the eccentric plate 79 and the chain 73 orbits the sprocket 68 on the terminal side, whereby the traveling direction of the chain 73 is changed from the forward direction to the backward direction. At this time, the disks 121 and 122 holding the paper 51
By engaging the cut groove 16a of the frame 16 shown in FIG. 5 to close the contact of the limit switch, the air cylinder 115 is actuated to raise the disc 121, the paper 51 is released from the grip, and the pallet is released. 50 is loaded. The discs 121 and 122 which have released the grip of the paper 51 return to the chain line position of FIG. 2 through the reverse trajectory at the time of paper conveyance by the backward movement of the chain 73, and stop by the action of the limit switch. Worker is paper 5
During the conveyance of 1, the wrapping paper of the next paper 51 is opened and waits, and then the above operation is repeated. The lifting table 49 is a paper 5
Automatically lowers by loading 1 and lift table 123
Is automatically raised every time the paper 51 is conveyed. And
After the papers 51 are stacked on the pallet 50, the edges of the papers are aligned because the frame 42 is inclined and the vibrating plate 53 is swinging.

As is clear from the above description, according to the present invention, in the paper transporting device for the paper aligning machine, the paper gripping tool for gripping and transporting the paper is provided with a pair of fixed disks supported on the traveling arm side,
The movable disk is opposed to each fixed disk and is supported on the traveling arm side so as to be movable up and down, and the drive means for driving the movable disk, and the fixed disk and the movable disk have an axis line perpendicular to the plane of the drawing. Since it is supported rotatably around the axis, even if the paper that has been caught in the front is lifted by separately holding the paper between a set of upper and lower discs from a flat surface such as a lift table, another disc is used. Since this distortion is corrected when the paper is gripped, it is not necessary to hold the paper for all the paper grippers anytime, which improves workability and makes it easy to incorporate the paper conveyor into automated processes. Therefore, automation of printing work is promoted.
