Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet discharge device in a conveyor-type sheet-feed collating machine as shown in the drawings, in which sheets are placed on a conveyance table provided on a conveyor via a collating machine paper feed section. A chain conveyor installed at the top of the chain conveyor conveys a few sheets of collated paper while decelerating it on its outward journey, and receives the front end of the collated paper with a paper receiving claw that moves in parallel with the conveyance platform, temporarily aligning the sheets. When the receiving claw returns, the sheet of collected paper is slipped between it and the conveyance table that continues to advance, and is dropped onto the discharged paper pile to be stacked.

Fig. 1 is an explanatory diagram of a conventional sheet-fed collating machine and paper ejecting device, 14 is a transport platform equipped with a vertical paper aligning claw 26 at the rear, 19 is a paper ejection pile, 20 is a chain, and 2T is a paper feeder. 28 is a suction port, 29 is a collating paper, 30 is a vibrader sorting machine, and a plurality of conveyance tables 14 are attached to an endlessly rotating chain 20 at appropriately equal intervals. Paper feed piles 2T loaded with paper sheets to be collated are arranged in parallel at equal intervals on the lower side.

The paper sheets to be collated from each paper feed pile 2T are suctioned by the suction port 28 that moves up and down from the bottom side of the conveyance table 14 to the upper side. The collated sheets 29 on the conveyor table are sent out by a feed belt or the like, and piled up as a discharge pile 19 on 30 vibrader leveling machines for each number of sheets to be collated. Generally, such conveyor sheet-fed collating machines are popular in the A-half size, but the number of sheets to be collated is more than single-sheet collation, and most of them use a vibrator method for paper alignment. This was inconvenient for full-size work, especially when the number of sheets to be collated was large.

The present invention enables stable paper ejection and good paper alignment during collation work when collating a few or more full-size sheets, contributing to improved efficiency in sheet collation work. It is something to do.

If the present invention is explained according to the drawings, a plurality of conveyance tables 14 which convey sheets while collating them, are attached to a chain 20 at appropriately equal intervals, and have notched recesses 25 on the upper surface along the conveyance direction. and a plurality of paper feed piles 2T located below the conveyance table and stacking sheets to be sequentially sucked and collated onto the conveyance table.
Two or several paper ejection piles 19 are arranged in parallel at the rear, and each of the paper ejection piles 19 is positioned above the paper ejection pile 19 and moves in translation with respect to the conveyance table 14 while decelerating on the outward journey, and is moved to a desired position at the rear upper part of the paper ejection pile. A paper receiving pawl 9 that can reciprocate within the conveyor table cutout recess 25 so as to return to its original position, a pawl lifting guide 11 that moves the final receiving pawl up and down, and a solenoid 13 that moves the pawl lifting guide up and down. Then, the solenoid is linked with the reset counter and can be instantly switched to operate the paper receiving claw of the next paper output pile 19'', so that the collated paper 29 that is discharged to the paper output pile is
a paper receiving rod 15 that receives the primary paper, and rear and side paper alignment plates 22 that align the collated papers stacked on the output pile.
. This is the paper ejection device of the machine.

Further, the present invention will be explained with reference to the drawings.

In FIG. 2, the conveyor platform 14 is
The conveyor table has a space at the front and rear thereof for feeding sheets of a sheet pile 27 prepared for collation from the lower part of the chain by a suction feeder 28.

A paper aligning claw 21 is provided at the rear end of the conveyance table 14 . The paper receiving claw 9 located above the conveyor chain 20 is connected to and operated by an operating rod 10 having rollers via a support shaft,
It is fitted into a mounting bracket 7 which is secured to the slide rod 5 by a locking bolt 8. The slide rod 5 reciprocates in connection with a rod 4 that is fitted into a guide 6 and communicates with a swing rod 2 which swings as the cam 3 rotates. Said operating rod 10
The roller portion moves along a claw lifting guide 11 whose one end is connected to a lever 12 and the other end is connected to an arm 12', and the claw lifting guide 11 is activated in accordance with an electrical input signal from a solenoid 13 connected to the lever 12. The rod 10 and paper receiving claw 9 are moved up and down. The paper receiving rod 15 is moved back and forth by the swinging of a lever 16 which is actuated by the rotation of the cam 1r.
The operation of the sheet discharging device of the sheet collating machine of the present invention begins with the conveyor conveyance table 14 shown in FIG. Immediately before the front end of the stand 14 passes the paper output pile 19, the solenoid 13 turns to zero.
When the N state is reached, the guide 11 is lowered and the paper receiving claw 9 is lowered to the upper surface of the conveyor table 14. While decelerating, the conveyor table 14 is translated for a while, and at this time,
The tip of the paper receiving claw 9 enters the notch 25 of the conveyance table 14, aligns the sheets while contacting the front end of the collated sheets, and when the front end of the conveyance table 14 has slightly passed the end of the discharged paper pile 19, As the cam 3 rotates, the paper receiving claw 9 returns to its return state, the paper aligning claw 21 opens, and the sheet collating paper 29 comes into contact with the paper receiving claw 9. During this time, the conveyance table 14 stops moving. Because of this, the sheet collated paper 29 on the conveyance table falls onto the paper receiving rod 15 of the paper discharge pile 19, and after the conveyance table 14 passes the paper discharge pile 19, the cam 17 By pulling out the paper receiving rod 15 by rotation, the sheets are loaded onto the discharge pile 19, and at the same time the rear and side alignment plates 22, 23 completely align the collated sheets.

Two or more paper discharge devices according to the present invention are installed in parallel at the rear of a sheet-fed collating machine, and the upper surface of the paper discharge pile 19 is always kept at a constant height by a detection unit 31 such as a photoelectronic switch or a micro switch. and maintain the optimal position required for paper ejection by the paper ejection pile elevating chain 24, and set the set number of collated papers side by side after ejection bye by the set counter. The solenoid 13 is activated so that the paper receiving pawl 9'' is lowered by the operation of the solenoid 13'' above the next paper output pile 19'', and the sheet collated paper can be automatically discharged to the paper output pile 19''. By automatically switching from one solenoid to the next solenoid 13'', it is possible to continuously discharge a set number of sheet collated sheets onto the output pile without stopping the sheet collating machine. By making it possible to switch manually by operating a button, it is possible to eject collated sheets properly during collation work, align the sheets, and reliably eject the set amount of collated sheets. As explained above, the present invention is capable of continuously and stably discharging paper onto a pile in a collating operation in which a large number of sheets are collated. The present invention provides a paper discharging device that can perform paper discharging and good paper alignment, and significantly contributes to improving the efficiency of sheet collating work and stabilizing quality.
