CONSTITUTION:A material board is placed on a carried board 14, transported by a conveyer 2 an stopped below a rail 9. A vacuum carrier 4 is moved by a running truck 6 over the conveyer 2 to the space above the material board 1. When the carrier 4 is moved downward to touch the upper surface of the material board 1, the material board 1 is attracted to the lower surface of the carrier 4 by suction force. Then, the carrier 4 is moved upward and further shifted toward a table 3 due to travel of the running truck 6. Then, the carrier 4 is lifted up to the height where is lower surface stays below the top end of a cutter 5. Therefore, the material board 1 is cut by the cutter 5 when the carrier 4 is shifted. Then, cut pieces of material board 1 are placed on a pallet 39 and a blower 35 is stopped in its operation to eliminate adsorptive effect to get the carrier 4 moved upward. The cycle is repeated until an assigned quantity of material board 1 are transported.

Description

[Detailed description of the invention]

[Technical Field] The present invention relates to an apparatus for cutting board materials such as asbestos slate green sheets while transferring them from a conveyor to a table.

[Background technology 1] Board materials such as asbestos slate green sheets are made using a paper-making device, cured on a conveyor, transferred from the conveyor to a table, and then packed onto pallets and sent to the next process. However, since the plate material needs to be divided into sizes that are easy to handle, it is necessary to cut the plate material when transferring it from the conveyor to the table. Therefore, various types of devices are available for cutting a board while transferring it from a conveyor to a table, such as one shown in FIG. 6. In other words, the device 6 in the ttSO diagram includes a conveyor 2 such as a roller conveyor and a table 3 with a lift 7.
A belt conveyor 8 on which a belt such as felt is suspended is disposed between the belt conveyor 8 and the rail 9 extending from above the conveyor 2 to above the table 3 so that the upper surface of the belt conveyor 8 is placed below the approximate center of the rail 9. A cutter 5 is provided which is rotationally driven so as to face the conveyor 2 and the cutter 5, and a traveling cart 10 which is driven to run along the rail 9 when the conveyor 2 and the cutter 5 are opened, and a cutter 5 which is driven to run along the rail 9 between the cutter 5 and the table 3. A traveling carriage 11 which is driven to travel is attached to a rail 9, and a vacuum carrier 12 for taking out and a vacuum carrier 13 for loading which are driven vertically are attached to each of the carriages 10 and 11, respectively. In this device, when the plate material 1, such as an iron plate, placed on the carrier plate 14 and conveyed by the conveyor 2 reaches the bottom of the vacuum carrier 12 for removal,
This vacuum carrier 12 descends, picks up the plate material 1 on the underside of the vacuum carrier 12 and picks it up, transfers the plate material 1 onto the belt conveyor 8 by moving the traveling cart 10, and then causes the belt conveyor 8 to run. While moving on the belt conveyor 8, the plate material 1 is cut by the cutter 5. The plate material 1 cut in this manner is adsorbed by a loading vacuum carrier 13 and transferred from the belt conveyor 8 onto the table 3. In this way, the plate material 1 is cut while being transferred from the conveyor 2 to the table 3. However, this device requires two vacuum carriers, one for take-out 12 and one for loading 13, and also requires a belt conveyor 8 to be installed between the conveyor 2 and table 3, making the device There were problems in that it was large-scale and complicated and required a large amount of installation space. Therefore, a device as shown in FIG. 7 is also provided. In this device, only one vacuum carrier 15 is provided and no belt conveyor is provided, but instead, a rotatably driven cutter 5 is attached to a traveling cart 16 on which the vacuum carrier 15 is provided. be. In this device, the plate material 1 on the conveyor 2 is transferred to the table 3 by moving the vacuum carrier 15 between the conveyor 2 and the table 3.
When the carrier plate 14 is moved from the table 3 side to the conveyor 2 side, the cutter 5 moves the carrier plate 14 by the traveling cart 16.
The plate material 1 placed on the conveyor 2 is cut. Therefore, this device uses only one vacuum carrier, does not require a belt conveyor, can cut the plate material 1 while being transferred from the conveyor 2 to the table 3, and can make the device compact. However, in this case, since the canter 5 is attached to the running platform L16, the running platform 16 becomes heavy, and the speed when running the running platform 11116 along the rail 9 becomes slow, resulting in a reduction in production efficiency. There is a problem that the amount decreases. [Objective of the Invention 1] The present invention has been made in view of the above points, and provides a plate material transfer/cutting device that can be formed compactly and that does not cause the risk of reducing production efficiency. The purpose is to provide [Disclosure 1 of the Invention] The plate material transfer/cutting device according to the present invention includes a conveyor 2 on which the plate material 1 is conveyed, a table 3 on which the plate material 1 is loaded, and an upper part of the conveyor 2 and one side of the table 3. a traveling trolley 6 that is driven to reciprocate when opened; a vacuum carrier 4 that is attached to the lower side of the traveling trolley 6 so as to be freely movable up and down and that sucks the plate material 1 on the lower surface and transfers it from the conveyor 2 to the table 3; It is characterized by comprising a cutter 5 disposed between the conveyor 2 and the table 3 for cutting the plate material 1 which is attracted to the lower surface of the vacuum carrier 4 and is moved from the conveyor 2 to the table 3. By configuring the apparatus in this manner, the above object is achieved.The present invention will be described in detail below with reference to Examples. The conveyor 2 is formed as a roller conveyor by rotatably attaching a row 218 between the horizontal members 19 on both sides as shown in Fig. 2, and a table 3 is installed on the side of the conveyor 2 as shown in Fig. WS1. It is arranged. Table 3 is the third
As shown in the figure, it is designed to be raised and lowered by 97 points 7. Further, a pair of parallel rails 9 are provided between the upper side of the conveyor 2 and the upper side of the table 3, which are attached to a frame 21 supported by pillars 20. The traveling trolley 6 is formed by attaching wheels 22 to both sides, and by rolling these wheels 22 along the rails 9, the traveling trolley 6 is configured to travel in an open position between the top of the conveyor 2 and the top of the table 3. . As shown in FIG. 2, one sprocket shaft 24 of the pair of sprocket shafts 24.25 is driven to rotate by the motor 23, and the sprocket 26 of both sprocket shafts 24.25 is spaced between the traveling carriage 6. A chain 27 is attached, and the carriage 6 is driven by a motor 23. The vacuum carrier 4 is mounted on the traveling base 11 as shown in Fig. 4 (aHb).
It is formed by providing a plurality of guide grooves 28 on the lower surface parallel to the traveling direction of the roller 6, that is, parallel to the toe rail 9, and the inside is hollow and a large number of suction ports 29 are provided on the lower surface as shown in FIG. It is. Further, a brush 30 made of nylon or the like is provided in the guide groove 28 so as to hang downward from the upper bottom surface of the guide groove 28, so that the guide groove 28 is filled with the brush 30. This vacuum carrier 4 is attached to the underside of the traveling carriage 6 by means of a telescopic suspension member 3 for vertical movement. A cylinder 32 is attached to the traveling carriage 6, and a wire 33 connected to the cylinder 32 is attached to the vacuum carrier 4.
is coupled to the vacuum carrier 4 via a pulley 34, and the vacuum carrier 4 can be driven up and down by being pulled up and down by a wire 33 by the operation of the cylinder 32. The frame 21 is equipped with a suction blower 3 as shown in FIG.
5 is attached, and a duct 36 connected to a suction blower 35 is connected to the upper surface of the vacuum carrier 4. Furthermore, as shown in Figure 1, conveyor 2 and table 3
A round-blade cutter 5 rotatably driven by a motor 38 supported on a base 37 is arranged between the guide grooves 28 of the vacuum carrier 4.
It is placed at a position corresponding to . Therefore, the plate material 1, such as a green sheet made of asbestos slate, is placed on the carrier plate 14, such as an iron plate, and conveyed to the conveyor 2.
However, when it reaches below the rail 9, it is stopped by a stopper or the like. Then, the vacuum carrier 4 is moved by the traveling cart 6 above the conveyor 2 onto the plate material 1, and the vacuum carrier 4 is moved down to bring the vacuum carrier 4 into contact with the upper surface of the plate material 1. Then, inside the vacuum carrier 4 is a suction blower 35.
The vacuum carrier 4 is in a reduced pressure state, and the plate material 1 is attracted to the lower surface of the vacuum carrier 4 by the suction force from the suction port 29 on the lower surface. Next, the vacuum carrier 4 is moved upward, and further, the vacuum carrier 4 is moved toward the table 3 by the running of the traveling trolley 6. At this time, the vacuum carrier 4 is moved up to a position where its lower surface is slightly lower than the upper end of the cutter 5.
Plate material 1 on the bottom surface of vacuum carrier 4
is cut by cutter 5. At this time, as shown in FIG. 5, the cutter 5 cuts the plate material 1 with the upper end inserted into the guide groove 28 of the vacuum carrier 4, but since the brush 30 is provided in the guide groove 28, Then, the upper surface of the plate material 1 is pressed by the brush 30 at the guide groove 28 portion, and the cutter 5
It is possible to prevent the plate material 1 from being bent into the guide groove 28 due to the pressure caused by the cutting process, and it is possible to make the cut surface beautiful without forming any cracks, improve the cutting accuracy, and suppress the generation of dust. . The vacuum carrier 4, which adsorbs the plate material 1 cut into a plurality of pieces by the sea urchin cutter 5 onto its lower surface, is moved above the table 3 by the traveling cart 6, and then the vacuum carrier 4
is moved downward to place the plate 1 on the pallet 39 on the table 3, and the suction blower 35 is stopped to release the suction of the plate 1 by the vacuum carrier 4. After this, the vacuum carrier 4 move up. In this way, one cycle of cutting the plate material 1 while being transferred from the conveyor 2 to the table 3 is completed, and thereafter cutting is performed while sequentially transferring the plate material 1 from the conveyor 2 to the table 3 in the same manner. When a predetermined number of plates 1 have been transferred onto the table 3, a 7 oak 4° of 7 oak lifts is inserted into a pallet 39 to transport the plates 1 to the next process, as shown in FIG. In the above embodiment, a roller conveyor is used as the conveyor 2, but a belt conveyor may also be used. If such a belt conveyor is used, the plate material 1 can be placed on the carrier plate 14. There is no need to transport it in a closed state. In this regard, in the apparatus shown in FIG. 7, the cutter 5 cuts the plate material 1 on the conveyor 2, so the conveyor 2
It is not possible to use a belt conveyor. Further, in the above embodiment, since the cutter 5 cuts the plate material 1 with its upper end housed in the guide groove 28 of the vacuum carrier 4, damage to the cutter 5 and wear and tear on the vacuum carrier 4 do not occur. In this respect, in the case shown in FIG. 6, the cutter 5 comes into contact with the surface of the belt conveyor 8, so that the cutter 5 is damaged and the belt conveyor 8 is severely worn out. [Effects of the Invention] As described above, in the present invention, a vacuum carrier is attached to the lower side of a traveling cart that is driven to reciprocate between the upper part of the conveyor and the upper part of the table, so that it can be freely driven up and down, and the vacuum carrier is moved vertically. When transferring the plate material adsorbed to the bottom surface from the conveyor to the table, the plate material is cut by a cutter placed between the conveyor and the table, so the plate material can be transferred using one vacuum carrier. It is possible to cut the material while cutting, and there is no need to use two vacuum carriers or a belt conveyor to move the board between the conveyor and the table as in the past, making the device more compact. It is something that can be done. Moreover, there is no need to attach a cutter to the traveling carriage as in the conventional case, and the running speed of the traveling carriage does not slow down, so that production efficiency does not decrease. By the way, in the device shown in Figure 7, the plate material transfer cycle is 12 seconds/
However, in the present invention, the cycle time can be shortened to 8 seconds/cycle.
