Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a work supporting device mounted on a parallel link mechanism of a building material mounting machine that mounts a stone plate or the like to a building frame at a construction site.

[0002]

[Prior Art]

 As a building material mounting machine, a revolving structure of a bogie is provided with a parallel link mechanism, a work support device is attached to the tip of this parallel link mechanism, and a stone material is supported by this work support device and transported to the mounting position for mounting It has been known. As the above-described work supporting device, for example, as shown in FIG. 1, an X-shaped arm b is rotatably attached to a main body a, and a vacuum suction pad d is attached to a tip end of the arm b. It is known that each of the vacuum suction pads d is connected to a vacuum generation source of the main body a by a hose and the work is sucked and supported by the vacuum suction pad d.

[0003]

[Problems to be solved by the device]

 Since such a work supporting device can rotate the vacuum suction pad d about the rotation axis c with respect to the main body a, the work can be adjusted by rotating the work with respect to the main body a when mounting the work, but the work does not rotate. As described above, the worker must hold and hold it by hand, which makes the work very troublesome.

Therefore, an object of the present invention is to provide a work supporting device capable of solving the above-mentioned problems.

[0005]

[Means for Solving the Problems]

 A member provided with a work support is rotatably supported by a shaft on a first member 18 provided on the main body 10, and an arc-shaped rotation guide plate 30 having a rotation center as a center is provided on this member. A plurality of locking holes 31 are formed in the rotation guide plate 30, a lock pin 35 is provided in the first member 18 so as to face the rotation guide plate 30, and the lock pin 35 is locked by a spring 37. Work support device urged to fit into.

[0006]

[Work]

 By pulling out the lock pin 35 from the lock hole 31 and slightly rotating the member, the lock pin 35 comes into contact with the rotation guide plate 30, and further rotation causes the lock pin 35 to slide along the rotation guide plate 30. It moves to fit into the other locking hole 31 and locks the member, so that the work support can be rotated, and when the work is supported and carried by the work support, the operator does not hold it by hand and rotate it. It is easy to operate because it does not have to be set.

[0007]

【Example】

 As shown in FIG. 2, a first horizontal link 3 is vertically swingably mounted on a base frame 2 which is provided on a traveling vehicle 1 so as to be rotatable, and a second horizontal link is attached to a tip portion of the first parallel link 3. 4 comprises a balance type link mechanism 5 which is swingably mounted up and down and moves by an external force, and a work supporting device 6 is attached to the tip of the second parallel link 4. As shown in FIGS. 3 to 9, the work supporting device 6 includes a main body 10 pivotally attached to a front end portion of the second parallel link 4, and a lower portion of the main body 10 faces the X direction (vertical direction). One shaft 11 is provided, one side hole 13 of the arm 12 is rotatably attached around the first shaft 11, and a shaft rod 16 having a block 15 is rotationally installed on the other side hole 14 of the arm 12. The first rod 18 is fitted with the shaft rod 16 and is retained by the retaining pin 17 to form the first member 18, and the second shaft facing the Y direction (front-back direction) into the shaft hole 19 formed in the block 15 of the first member 18. 20 is rotatably fitted, the second shaft 20 is fixed with a nut 21, and the middle portion of the third shaft 22 in the longitudinal direction facing the Z direction (left-right direction) is fixed to the second shaft 20. Fit both sides of the third shaft 22 in the longitudinal direction into the holes 25 of the block 24 provided in the pair of frames 23. Nuts 26, and a work support, such as a vacuum suction pad 27, is attached to each frame 23. The Y-axis rotation bearing portion is offset forward from the X-axis rotation bearing portion, and the Z-axis rotation bearing portion is It is offset forward from the Y-axis rotation bearing. The third shaft 22 is provided with an arcuate rotation guide plate 30 centered on the center of the second shaft 20, and the rotation guide plate 30 has a pair of locking holes 31, 31. A stopper 32 is provided integrally with the lock hole 31 closer to the end in the rotation direction than the lock hole 31, and a cylindrical body 34 is provided on the mounting plate 33 fixed to the block 15. Then, the lock pin 35 is fitted and inserted into the cylindrical body 34, and the lock pin 35 is urged by the spring 36 so that one end fits into the lock hole 31 and the other end is fitted. A knob portion 37 is provided, and the lock pin 35 has a perfect circular shape, and the locking hole 31 has an oval shape, so that the lock pin 35 can be relatively displaced relative to the locking hole 31 in the rotational direction.

Next, the operation will be described. By rotating the first member 18 around the first shaft 11, the vacuum suction pad 27 can be pivotally moved around the first shaft 11, and by rotating the second shaft 20 with respect to the block 15, the vacuum suction pad 27 can be rotated. Can be rotationally moved around the second axis 20, and since the Y-axis rotary bearing is offset from the X-axis rotary bearing, the rotary movement range can be increased without interference between the respective parts, and the frame 23 can be moved to the third axis. By rotating around 22, the vacuum suction pad 27 can be vertically swung about the third axis 22, and since the Z-axis rotation bearing part is offset from the Y-axis rotation bearing part, each part interferes. You can increase the swing range without swinging. Further, since the shaft rod 16 can be removed by pulling out the retaining pin 17, and different work supports can be assembled by inserting a different work support, for example, a frame 23 to which a clamp is attached from above. Therefore, different work supports can be easily replaced. Can be installed. When rotating the third shaft 22 with respect to the block 15 about the second shaft 21 as described above, the lock pin 35 is pulled out against the spring 36 by holding the knob 37 and pulled out from the lock hole 31. When the third shaft 22 is slightly rotated, the knob 37 is released to bring the lock pin 35 into contact with the rotation guide plate 30, and when the third shaft 22 is rotated 180 degrees, the lock pin 35 is fitted into the other locking hole 31. Then lock it to prevent it from rotating. In this way, by pulling out the lock pin 35, the third shaft 22 can be rotated 180 degrees and the vacuum suction pad 27 can be rotated 180 degrees to be locked, so that the work is supported and the link mechanism 5 is rocked up and down. It is not necessary for the operator to hold it by hand when transporting it by hand and hold it so that it can rotate the supported work by 180 degrees if necessary, and the locked state is the looseness of the lock hole 31 and the lock pin 35. Since it can be rotated by a minute, it can be finely adjusted when mounting the work. It should be noted that two or more locking holes 31 may be formed in the rotation guide plate 30 so that the rotation guide plate 30 can be locked at an arbitrary angular position. Further, when the lock pin 35 is pulled out and rotated in the opposite direction, the lock pin 35 interferes with the stopper 32 for preventing the lock pin 35 from being removed from the rotation guide plate 30.

[0009]

[Effect of the device]

 By pulling out the lock pin 35 from the lock hole 31 and slightly rotating the member, the lock pin 35 comes into contact with the rotation guide plate, and further rotation causes the lock pin 35 to slide along the rotation guide plate 30. Since the member is locked by being fitted into the other locking hole 31 by the lock, the work support can be rotated, and when the work is supported and carried by the work support, the operator does not have to hold the work by hand and rotate it. The operation is easy because it is not necessary.
