Next, the method of using the above equipment will be described. As shown in FIG. 1, the self-propelled transport train 4 of the suspension transport device 2 is placed at a predetermined position above the starting end of the stacked rear sheet transport conveyor 1. If stopped, the lifting / lowering body 6 of the train 4 is lowered to a predetermined level by the unwinding of the belt 5. As a result, the horizontal support portion 8a of the hanger 8 descends below the conveyor chains 1a, 1b of the conveyor 1, and the two sheets 7a, 7b leaning diagonally on the hanger 8 are conveyed by the conveyor 1 Transfer to the conveyor chains 1a and 1b. At this time, it is assumed that the upper sheet 7b slides forward and is obliquely supported between the front end of the upper surface of the lower sheet 7a and the conveyor chains 1a and 1b as illustrated. Of course, two sheets 7
Even if the a and 7b are horizontally stacked on the horizontal support portion 8a of the hanger 8, when the conveyor chains 1a and 1b are unloaded to the rotating state, the lower sheet 7a The leading sheet 7b, which is on the upper side, is the sheet 7
It may be supported obliquely between the rear end of the upper surface of a and the conveyor chains 1a and 1b.

In any case, the sheets 7a and 7b transferred from the hanger 8 onto the conveyor 1 are
Of the conveyor chains 1a and 1b, but before the sheets 7a and 7b arrive at the sheet stacking state correcting device 11 of the next stage, the stopper 13 of the device 11 is lowered by the cylinder unit 19 to the lower limit position (action). position)
And lower it. Of course, the seat rear pusher 14 is returned to the backward rising limit position and made to stand by, and the seat support plates 16a ...
16c is lowered from the sheet supporting surfaces of the conveyor chains 1a and 1b, the sheet pressing tool 17 is made to stand by at the upper limit position, and a pair of left and right sheet moving tools 18a,
18b are kept waiting at the backward limit position.

Sheets 7a conveyed by the conveyor 1,
Of the 7b, the preceding sheet (sheet 7 in the illustrated example
After the tip of b) contacts the stopper 13, the conveyor chains 1a and 1b are stopped with a slight time delay, and then the sheet post-pressing device 14 and the sheet supporting plates 16a to 1b.
6c, sheet pressing tool 17, and sheet moving tool 18
Each of a and 18b is moved from the standby position to the working position.
That is, as shown in FIG. 4, seat support plates 16a to 16a
After c is raised to the upper limit position by the cylinder unit 29 and the sheets 7a and 7b are lifted above the sheet supporting surfaces of the conveyor chains 1a and 1b, the pair of left and right sheet shifters 18a and 18b are moved to the cylinder unit 3.

After that, the rodless cylinder unit 23 is moved forward to push the seats 7a and 7b on the seat support plates 16a to 16c at the delayed position (the seat 7a in the illustrated example) with the seat pusher 14. Then, the sheets 7a and 7b are corrected to a normal stack state. The sheet 7a is pushed by the sheet back pushing tool 14.
If the sheet pressing member 17 is lowered to the lower limit position by the cylinder unit 32 before pushing, the inclined sheet 7b is prevented from standing up, and the pushed sheet 7a is securely moved. You can enter the lower side.

When the operation of the above-described sheet stacking state correction device 11 is completed, the stopper 13, the sheet post-pressing tool 14, the sheet supporting plates 16a to 16c, the sheet pressing tool 17, and the sheet moving tools 18a, 18b are respectively removed. To the standby position, and the sheets 7a and 7b in the stacked state on the sheet support plates 16a to 16c are returned to the original conveyor chain 1.
By returning the sheets 7a and 7b to the normal stacking state, the sheets 7a and 7b corrected to the normal stacked state can be conveyed again by the conveyor 1, but these sheets 7a and 7b are transferred to the stacked sheet feeding device 12 at the end of the conveyor. Before arriving, as shown in FIG.
.. to 35c are returned to the standby position A, and the stopper 37 is lowered by the cylinder unit 44 to the lower limit position (the position for receiving the sheet). Of course, the sheet pressing / fixing platen 38 is raised to the ascending limit position by the cylinder unit 45 and kept in standby.

When the stacked sheets 7a and 7b are received by the stopper 37 of the stacked sheet feeding device 12 as shown in FIG. 1, the conveyor chains 1a and 1b are stopped with a slight time delay. Next, the sheet pressing / fixing platen 38 is lowered by the cylinder unit 45, and the sheet lifting bases 35a to 35c are rotated by the cylinder units 41 and 42 of the driving means 36 toward the sheet discharging position B around the horizontal rotation shaft 39. Let

As a result, the stacked sheets 7a and 7b on the conveyor 1 are raised by the ascending sheet lifting table 35a.
35c, the seat lifting platform 35a ~ 35
At the same time as being lifted by c, it is pressed and fixed to the sheet lifting bases 35a to 35c by the sheet pressing / fixing platen 38 descending with respect to the sheet lifting bases 35a to 35c. Then, as shown in FIG. 7, when the sheet lifting bases 35a to 35c arrive at the sheet discharging position B and stop, the stopper 37 is lifted and opened by the cylinder unit 44. At this time, the sheets 7 in the stacked state are stacked.
Since a and 7b are sandwiched between the sheet pressing and fixing plate 38 and the sheet lifting bases 35a to 35c, as the stopper 37 is opened, the sheets 7a and 7b are sequentially lifted from the lower side. It does not slide down from the top of the tables 35a to 35c.

When the stopper 37 reaches the upper limit position and is completely opened, the sheet pressing and fixing plate 38 is raised by the cylinder unit 45 to release the fixed sheets 7a and 7b. Sliding down from the sheet lifting bases 35a to 35c all at once and receiving box 5
Since the sheets are housed in 0, there is no risk that the two sheets 7a and 7b will come apart and lose their posture.

[0021]

As described above, according to the stacked sheet feeding apparatus of the present invention, the sheet lifting table is rotated upward after the sheet conveyed in the stacked state on the conveyor is received by the stopper. The sheet pressing and holding plate, which moves integrally with the sheet lifting base, is lowered to clamp and hold the stacked sheets between the sheet lifting base and the sheet lifting base. Can be done.

Therefore, when the sheet lifting base reaches the sheet discharging position and opens the stopper, the sheets in the stacked state are sequentially slid down from the lower side of the sheet lifting base along with the opening movement of the stopper. Since the sheet pressing and fixing platen is lifted after the stopper is completely opened, the released sheets in the stacked state are slid off from the sheet lifting table all at once, and the sheet is sent out. There is no risk that the sheets will fall apart and the order of arrangement will change, or that the posture will change significantly.
