The wooden panel feeder 3 takes out the wooden panel 4 from the wooden panel storage section 5 and places it on the belt conveyor 2.The operation will be explained in detail below. The lifting cylinder 13 is lowered on the storage section 5, the plurality of suction cups 14 are brought into pressure contact with the wooden panel 4, and the inside of the suction cup 14 is brought into a vacuum state by the operation of the vacuum device 21, so that the wooden panel 4 is sucker 14
adsorbs to. After the lifting cylinder 13 rises, the movable plate 12 on which the suction plate 15 and the lifting cylinder 13 are arranged is guided in a direction perpendicular to the traveling direction of the belt conveyor 2 by the operation of the sending cylinder 11. It slides along the rail 10 and stops at a position above the belt conveyor 2 on which the wooden panel 4 is placed by the wooden panel feeder 3 . Then, the lifting cylinder 13 is lowered until there is a slight gap between the suction cup 14 and the belt conveyor 2, and the switching valve 18 is switched to supply compressed air from the compressor 20 to the suction cup 14. The wooden panel 4 falls and is placed at a predetermined position on the belt conveyor 2. At this time, if the raised position of the lifting cylinder 13 is set to be slightly higher than the height of the belt conveyor 2, there is no need to lower the lifting cylinder 13 again due to the falling of the wooden panel 4. still,
A separate vacuum device 21 is provided for each of the plurality of suction cups 14.
If a compressor 20 is provided to supply a vacuum state and compressed air, the adsorption of the wooden panel 4 can be made more reliable. Then, the movable board 12 returns to the wooden panel storage section 5 again, and the next wooden panel 4 is adsorbed.

By the way, as shown in FIG. 6, the length W of the wooden panel 4 is almost constant depending on the cutting of the wood, but
When slicing cut wood, the width L differs depending on whether it is closer to the center or closer to the circumference. Therefore, in the width direction of the belt conveyor 2, the overlapping width A of the wooden panels 4 is constant without any special operation, but in the direction of movement, the width L of the wooden panels 4 is constant. Since there are variations in the width, if the wooden panel feeder 3 supplies the wooden panels 4 at regular intervals, the overlapping width B will vary. On the other hand, in this embodiment, the photocell 17
Taking advantage of the fact that the light irradiated from the wooden panel 4 is absorbed by the wooden panel 4 and reflected by the belt conveyor 2 to put the phototube 17 in a detection state, the phototube 17 is installed in each wooden panel feeder 3 and the belt conveyor 2 also moves, and when the end of the wooden panel 4 passes the light emitted from the phototube 17, this light is reflected by the belt conveyor 2 and the phototube 17 enters the detection state. Become. Depending on this detection state, the wooden panel feeder 3 feeds the next wooden panel 4 onto the belt conveyor 2.
Place it on top. At this time, by setting the timing between the moving speed of the belt conveyor 2 and the supply speed of the wooden panel 4, a constant overlapping width B can be obtained regardless of the difference in the width L of the wooden panel 4.

In this way, as the belt conveyor 2 moves, each wooden slat feeder 3 sequentially places the wooden slats 4 in its row, thereby allowing the wood siding feeder 3 at the last stage to
At the rear, that is, in the wide part of the machine stand 1, the overlapped portions of the four groups of wood panels arranged in parallel are sewn together by the first sewing machine 5 to form the wood panel sewn body 7. The waterproofing material 23 paid out from the roll 23' is superimposed on the upper surface of the wood stitched body 7 by the supply mechanism 22 via guide rollers 25 and 26, and the waterproofing material 23 and the wooden stitched body 7 are The sheets are transported in an overlapping state by the belt conveyor 2, and both ends thereof are sewn by the left and right second sewing machines 27, 27A to manufacture the roof base material 28.

The roof base material 28 manufactured in this way is transferred by the belt conveyor 2 via the feed roller 29, and is wound up by the winding roller 32 and rolled into the roll 3.
4 is formed. In this case, the feed length of the roof base material 28 is counted by a counter 30, and the cutter 33 cuts the roof base material 28 to a predetermined length.

As shown in FIGS. 8 and 9, the roof base material 28 manufactured in this manner includes the wood feather sewn body 7 and the waterproof material 23.
A one-piece roll 34 in which the edges are sewn into one piece.
Therefore, it only needs to be roofed once. Furthermore, no perforation holes are formed that penetrate the entire surface of the roof base material 28, and the sewn portions 36 at both ends of the roof base material 28 serve as overlapping margins, so that rain leakage is prevented.

FIG. 7 shows another embodiment of the wooden board feeder 3, in which the same parts as in the above embodiment are denoted by the same reference numerals. A delivery cylinder 42 with a pinion 41 is fixed. 43
is a moving rack that meshes with the pinion 41, and slides along the guide rail 44 in a direction perpendicular to the traveling direction of the belt conveyor 2 by being fed out by the feeding cylinder 42. A suction plate 15 having a plurality of suction cups 14 is disposed below the movable rack 43. 45 is this suction plate 1
It is a vibrator that vibrates 5 several times. The wooden panel storage section 5 is vertically movable by a push-up cylinder 46, and is pushed upward so that the top of the stored wooden panel 4 is always located above the belt conveyor 2.

According to such a configuration, the top of the wooden panel 4 is positioned above the belt conveyor 2 by the push-up cylinder 46. This top wooden panel 4
Since the suction cup 14 and the suction cup 14 are arranged to face each other with a slight gap, when the suction cup 14 is brought into a vacuum state, the wooden panel 4 is sucked up. At this time, the vibrator 45 vibrates to prevent the wooden panel 4 from being removed in two pieces. Next, the delivery cylinder 42 pushes out the pinion 41, so that the moving rack 43 meshing with the pinion 41 slides along the guide rail 44 and stops at a predetermined position. At this time, the movable rack 43 moves at about twice the speed of the cylinder 42 due to the engagement between the fixed rack 40 and the pinion 41. next,
When the vacuum state of the suction cup 14 is released and compressed air is supplied, the wooden panel 4 that has been sucked is forcibly dropped onto the belt conveyor 2 and placed thereon. In this way, since the suction plate 15 moves only in the horizontal direction, the time for supplying the wooden panel 4 is shortened. Furthermore, even when the suction plate 15 moves horizontally, the movable rack 43 can be moved faster than the speed of the delivery cylinder 42 due to the engagement with the fixed rack 40, pinion 41, and movable rack 43. Supply time can be shortened. Furthermore, since the vibrator 45 is provided, there is no need to take two wooden panels 4, and each wooden panel 4 can be reliably placed on the belt conveyor 2.

Note that the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, in the above embodiment, the wood panel feeder is used to automatically feed the wood panel, but the wood panel feeder may be used to feed the wood panel manually.
