In the batch stacking apparatus 1, a corrugated cardboard sheet 3 that is cut by dividing it into two laterally symmetrical planes having a predetermined length is conveyed between the conveying belts 2 arranged in parallel, and the conveying belts 2, Two-stage and one-stage batch conveyors 4 arranged in parallel on the horizontal plane
And a two-stage batch conveyor 5 which is bent in a substantially V shape and arranged side by side on the first-stage batch conveyor 4, and a one- or two-stage switching flap between the one-stage batch conveyor 4 and the two-stage batch conveyor 5. 6, the corrugated cardboard sheet 3 (cut into two sides at the center) is distributed to the first-stage batch conveyor 4 or the second-stage batch conveyor 5 and conveyed.

The first-stage batch conveyor 4 includes pulleys 21, 2
The lower belt 4a is composed of a lower belt 4a, and the upper belt 4b is composed of pulleys 23 and 24 at both ends and a tension pulley 25 in the center, leaving the starting end of the lower belt 4a.
The corrugated cardboard sheet 3 is conveyed between the lower belt 4a and the upper belt 4b.

The two-stage batch conveyor 5 is formed in a substantially V shape, and has a pulley 26 on the starting end of the lower belt 4a.
And belt 27 composed of 27 and tension pulley 28
a, the pulleys 29, 30 and the tension pulleys 31, 32, 33 on the upper belt 4b at the rear of the upper surface belt 5a.
And a lower surface belt 5b formed by interposing. Then, the corrugated cardboard sheet 3 is conveyed between the upper surface belt 5a and the lower surface belt 5b.

The 1st / 2nd-stage switching flap 6 is interposed between the 1st-stage batch conveyor 4 and the 2nd-stage batch conveyor 5, and a tapered flap 35 is fixed to the shaft portion 34. The tip end of the flap 35 is formed to move up and down by the reverse rotation. The conveyed corrugated cardboard sheet 3 is conveyed to an open path between the first-stage batch conveyors 4 when the flaps 35 are located above, and is conveyed to an open path between the second-stage batch conveyors 5 when the flaps 35 are located below. Are formed.

Downstream of the one-stage batch conveyor 4 or the two-stage batch conveyor 5, there are provided a width determining conveyor 7 and a feed conveyor 8 arranged side by side according to the present invention.
A center guide 10 having a reverse V-shaped cross section for dividing the corrugated board sheet 3 into two surfaces is arranged at the center of the width determining conveyor 7 so that the downstream is gradually higher. The width determining conveyor 7 is provided with a center partition plate 11 that gradually lowers from the height of the downstream side 10a of the center guide 10 toward the downstream side, and side joggers 12 that prevent the corrugated cardboard sheet 3 from protruding. ing.

The width determining conveyor 7 comprises a lower belt 7a consisting of pulleys 36, 37 and 38, 39 arranged side by side.
And the upper belt 7b composed of the pulleys 40 and 41, the corrugated cardboard sheet 3 is conveyed between the corrugated cardboard sheet 3 and the upper belt 7b.
It is divided into faces.

The feed conveyor 8 comprises pulleys 42, 4 on both sides.
The corrugated cardboard sheet 3 is accurately divided into two surfaces by a center partition plate 11 which is composed of a lower belt 8a composed of 3 and 44 (not shown) and 45, and which is arranged at the center of the corrugated cardboard sheet 3. Therefore, the two sheets do not overlap each other in the central portion and can be stacked in a batch.

The center guide 10 is positioned so as to be flush with or slightly lower than the surface of the lower belt 7a of the width determining conveyor 7 when it is not used.
The rear end is arranged so as to be movable upward with the front end as the fulcrum.

The center partition plate 11 is formed of a substantially rectangular plate, and has a rotatable fixing portion 11a protruding at a lower end and an upper tip 11b protruding at an upper end. When the two-faced corrugated cardboard sheet 3 is conveyed, the fixing portion 11a of the center partition plate 11 is rotated to move the upper tip 11b upward so that the center guide 10 has a downstream side 1a.
It is configured to push the inside of 1a upward, and is provided with a switching means for switching between use and non-use of the center guide 10 and the center partition plate 11. In addition, the center guide 10 and the center partition plate of the above-described embodiment are the one-stage batch conveyor 4
May be applied to the line.

Next, a method of carrying the corrugated board sheets 3 by the batch stacking apparatus 1 will be described. The cut corrugated cardboard sheet 3 is conveyed between the conveying belts 2 arranged side by side, and the flaps 3 are rotated by the rotation of the one- and two-stage switching flaps 6.
When 5 is located above, an open path is formed between the flap 35 and the second-stage batch conveyor 5, and the open path between the first-stage batch conveyors 4 is conveyed. Further, when the flap 35 is located below, a closed path is formed between the flap 35 and the first-stage batch conveyor 4, and the corrugated cardboard sheet 3 is formed to be conveyed in an open path between the second-stage batch conveyor 5.

The switching of the 1- and 2-step switching flaps 6 is usually performed alternately in 1-step or 2-step. Also, if necessary, you can switch the 1 and 2 stage switching flap 6 according to the order,
When the corrugated board sheet 3 is a double-sided liner paper, it may be conveyed to the first-stage batch conveyor 4, and when it is a single-sided liner paper, it may be conveyed to the second-stage batch conveyor 5. Further, the corrugated cardboard sheets 3 may be arbitrarily distributed to one or two stages by controlling the one- and two-stage switching flaps 6.

The corrugated cardboard sheet 3 conveyed to the above-mentioned one-stage batch conveyor 4 or the two-stage batch conveyor 5 is passed through the husband-width determining conveyor 7, the feeding conveyor 8, the discharging conveyor 9 and the press-feeding belt 13 which are provided downstream. Then, the sheets are successively conveyed and a predetermined number (for example, 60 sheets) are stacked in a batch.

From the viewpoint of the efficiency of the corrugated board manufacturing machine, the corrugated board sheet 3 divided into two symmetrical planes at the center of the corrugated board sheet 3 has an inverted V-shape when passing through the width determining conveyor 7 as described above. On the center guide 10 and the feeding conveyor 8 of FIG. In addition, batch loading on the feed conveyor 8 and conveyance to the discharge conveyor 9 are performed by the press feed belt 13 and the back stopper 14 that aligns the end surfaces of the corrugated cardboard sheet 3.
Are placed in batches. As a result, the corrugated cardboard sheet 3 can be smoothly fed to the back stopper 14.

This batch of corrugated cardboard sheets 3
As shown in FIG. 4, it is lowered from the lifting device 15 and is stacked on the pallet 18 by the down stacker device 17 through the reversing device 16 which reverses the 180 ° batch stacking in the case of single-sided liner paper by the reversing device 16. , And is sent by the roller 19.

The reversing device 16 can be applied to a single-sided liner paper to prevent load collapse due to batch stacking. On the other hand, in the case of double-sided liner paper, in order to prevent the warp of the sheets, the batch is similarly inverted by the reversing device 16 and stacked on the pallet 18 by the down stacker device 17.
