る。[Detailed Description of the Invention] The present invention relates to a loading device with a length detection function for building boards that automatically detects and loads the length of building boards.
The gist is that a conveyor 1 carries a building board 2 on it and conveys it, and a conveyor 1 that grabs the building board 2 conveyed by the conveyor 1 and is placed above the end of conveyance of the building board 2 by the conveyor 1. a building board transfer/loading device 5 for transferring and loading building boards 1 to another location; and a front end detector 3 for detecting the front end 2a of the building board 2 being conveyed on the conveyor 1.
At the same time as detecting the front end 2a of the building board 2, a rear end detector 4 moves to the opposite side of the conveyor 1 at the same speed as the transport conveyor 1 and detects the rear end 2b of the building board 2.
and a timer 6 that operates simultaneously with the detection of the rear end 2b of the building board 2 by the rear end detector 4 and stops the conveyor 1 so that the center of the building board 2 and the center of the building board transfer/loading device 5 coincide. A loading device with a building board length detection function is characterized by comprising:

た。 In conventional building board loading devices, a proximity switch is placed at the center of the building board transfer device to stop the building board by aligning the center of the building board transfer device with the center of the building board. Previously, the operator set a stop timer to control the stop of the conveyor according to the length of the building board, but with this method, the stop timer was set to match the length of the building board every time the length of the building board changed. There was a drawback that I had to change it.

The building board transfer/loading device 5 is located at the final end of the building board production line (A) as shown in Fig. 1, and 7 is an uncoiler, 8 is a roll forming machine, 9 is a foam resin injection device, and 10 is an uncoiler. A double conveyor 11 for foam curing of foamed resin is a cutting device for cutting molded building boards into predetermined dimensions, and a transport conveyor 1 is installed from this cutting device 11 to a building board transfer/loading device 5. As this conveyor 1, for example, a roller conveyor is used. A detector conveyor 12 having a rear end detector 4 is disposed below the conveyor 1 . A building board transfer/loading device 5 is disposed above the terminal end of the conveyor 1. Reference numeral 13 denotes a plurality of suction ports provided on the lower surface of the building board transfer/loading device 5. Usually vacuum suction is used. In this embodiment, the front end detectors 3 are provided at two locations below the conveyor 1, one at the front and the other, the front one being a long length front end detector 3a, and the rear one being a short length front end detector 3b. As the front end detector 3, for example, a proximity switch is used, and as the rear end detector 4, for example, a reflection type phototube is used. However, the cut short building board 2
When the short building board 2 is sent on the conveyor 1, the short building board 2 passes over the front end detector 3b for short lengths, and the front end 2a of the building board 2 is detected by the front end detector 3b for short lengths.
is detected. Then, the detector conveyor 12 moves at the same speed as the building board 2 in the opposite direction to the conveying direction. When the rear end 2b of the short building board 2 is detected, the timer 6 is activated, and the conveyor 1 is stopped after a predetermined period of time to align the center of the building board 2 with the center of the building board transfer/loading device 5. When the detector conveyor 12 detects the rear end 2b, it is reversely rotated by switching the clutch, and when the rear end detector 4 reaches its original position, it stops and prepares for detecting the next rear end 2b of the building board 2. Now, in this case, if the detection movement distance of the rear edge detector 4 is l 1 , then l 1 = L 1 (short building board (2)) - L 2 (front edge detector for short length (3b) and rear edge detector (4))/2 At this time, the center of the short building board 2 is located at the center between the front end detector 3b (origin) for short lengths and the rear end detector 4. Therefore, the set distance S1 of the timer 6 (of course, the distance is set by converting it into time) is: S1 = L2 /2+ L3 (short length front end detector (3b) and building board transfer/loading device ( 5)) Here, if L 2 = 1800 and L 3 = 800, then S 1 = 1700
(unit: mm), and the time corresponding to S 1 is set by timer 6.
All you have to do is set it to . In this case, since both the building board 2 and the rear end detector 4 move at the same speed and in opposite directions, the dimension of S 1 is constant regardless of the length of the building board 2. Therefore, even if the length of the building board 2 is different, there is no need to reset the timer 6. Furthermore, by providing the timer 6, slippage of the building board 2 and other errors can be absorbed and corrected. In this way, the short building board 2
When the conveyor 1 is moved by S 1 , the timer 6 works to stop the conveyor 1, and then the building board transfer/loading device 5 descends and picks up the two suction ports 13 on the inside of the short building board 2. Then, the building board transfer/loading device 5 is moved to transfer the building board 2 to the loading location, and then, as it descends, the suction is removed and the building board 2 is loaded.
以上の点は長尺の建築板２の場合でも同じで、
この場合は、長尺用前端検出器３ａを基準にす

長尺用前端検出器３ａまでの距離である。また、
この場合、吸着口１３は４個使用するので、建築

尺に切換える時は内側の２個の吸着口１３のみが
働くように連動しておく。 The above points are the same in the case of long building board 2,
In this case, the long front end detector 3a is used as a reference. In the figure, L4 is the distance from the center of the building board transfer/loading device 5 to the long front end detector 3a. Also,
In this case, four suction ports 13 are used, so when switching from short to long building board 2, all four suction ports 13 work, and conversely, when switching from long to short building board 2, all four suction ports 13 work. The two inner suction ports 13 are linked together so that only they work.

3500mm, L 2 = 1800mm, L 3 = 800mm, L 4 = 2600
mm, the measurement range of the front end detector 3b for short lengths is 1800 to 8800mm, and the front end detector 3a for long lengths is 1800 to 8800mm.
Then it will be 5200 to 12200mm. In addition, when there is no switching switch (not shown) for the front end detectors 3a and 3b for long and short lengths, that is, when the front end detector 3 is located at one location, when measuring a 12 m long building board 2, The moving distance of the end detector 4 is 5.1 m (that is, (12 m - 1.8
m)/2=5.1m), but when the front end detector 3b for short length and the front end detector 3a for long length are provided, by detecting with the front end detector 3a for long length, the rear end detector 4 can be detected. The amount of movement is 3.4m (that is, (12m - 2.6m - 1.8m)
-0.8m)/2=3.4m), and compared to the case where there is one front end detector 3, the front end detector 3
By locating the rear end detector 4 at two locations in this way, the amount of movement of the rear end detector 4 can be kept to a minimum, improving accuracy and solving installation problems. Further, the detector conveyor 12 is linked with the conveyor 1,
When the transport conveyor 1 stops during length measurement, the detector conveyor 12 also stops, so that accurate length measurement can be continued.
本発明は叙上のような構造であるので、
建築板に無接触で測長を行うことができ、装
置による疵の発生がない。 Since the present invention has the above-mentioned structure, the length can be measured without contacting the building board, and no defects are caused by the device.
記憶装置等を使用せず、直接建築板を測長す
るので、建築板移送積載装置をオフにして建築
板を搬送コンベア上を通過させる場合でも測長
できる。 Since the length of the building board is directly measured without using a storage device, the length can be measured even when the building board transfer/loading device is turned off and the building board is passed on the conveyor.
前端検出器を基準とし、後端検出器の移動及

長さの建築板の測長が行えるものである。 Using the front edge detector as a reference, the rear edge detector always detects the rear edge of the building board even if the length of the building board changes as appropriate during transfer and loading operations due to the movement of the rear edge detector and the action of the timer. The center of the building board is located a certain distance from the center of the building board transfer/loading device, and the length of building boards of various lengths can be measured without adjusting the timer.
タイマの使用により、建築板の滑りや誤差な
ど現実に発生する誤差を吸収及び補正ができて
実際の現場作業に合せた操業が可能になる。 By using a timer, it is possible to absorb and compensate for errors that actually occur, such as slippage and errors in building boards, making it possible to operate in line with actual site work.
建築板がどのようなタイミングで流れて来て
も現物測定方式なので自動的に測長が可能であ
り、建築板移送積載装置にて移送積載できる。 No matter what timing the building boards come in, the length can be automatically measured using the actual measurement method, and the building boards can be transferred and loaded using the building board transfer and loading device.
装置が簡単で安価である。 The device is simple and inexpensive.
