Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an angle adjustment device for an iron hand used for moving a workpiece.

[Conventional technology]

Generally, an iron hand device is used to move, for example, a pressed workpiece from a press machine to another location.

FIG. 4 shows such a conventional iron hand device. In this device, a workpiece is held by the suction cup 2 of the iron hand jyo 3, which is composed of a support rod 1 and a suction cup 2 fixed to the tip of the support rod 1. 4 is adsorbed. The iron hand 3 moves horizontally along a guide rod 6 by driving an air cylinder 5. On the other hand, as the support member 8 disposed on the iron hand main body 7 moves up and down, the iron hand 3 is moved in the vertical direction.

In such an iron hand device, the horizontal and vertical angles of the iron hand 3 with respect to the work 4 are important issues in order to securely attract the work 4. Therefore, in the conventional iron hand angle adjustment device, a vertical position holding member 9 is supported on a support member 8 disposed on the iron hand body 7 so as to be freely rotatable in the vertical direction with a pin 10 as a fulcrum, and the nut 12 is rotated. The position of the bracket 11a relative to the bolt 11 is changed by the movement, and the vertical angle of the support member 8 and the vertical position holding member 9 disposed on the iron hand body 7 is changed, thereby changing the vertical angle of the iron hand jaw 3. is being carried out. On the other hand, the horizontal angle of the iron hand holder 3 can be adjusted by supporting an iron hand holder rotatably supported by a horizontal position holding member 13 fixed to a vertical position holding member 9, as shown in FIG. This is done by rotating the member 14. That is, this is done by loosening the adjustment bolt 15 that supports the iron hand jaw support member 14, and moving the adjustment bolt 15 along the elongated hole 17 using the pin 16 as a fulcrum.

[Problem that the invention attempts to solve]

However, in the iron hand angle adjustment device configured as described above, the vertical angle is adjusted by the nut 12 screwed onto the bolt 11, and the horizontal angle is adjusted by the adjustment bolt 15. However, there is a problem in that adjusting the angle is very troublesome and takes a lot of time. Additionally, when adjusting the angle, it is necessary for a worker to get close to the iron hand device and manually adjust the angle. For example, if a conveyor is placed below the iron hand device, work efficiency will be extremely poor. There's a problem.

[Purpose of invention]

The present invention has been developed in response to the above-mentioned problems, and makes it possible to quickly and accurately adjust the angle of the iron hand jyo, as well as to easily enable remote control and improve work efficiency. The present invention aims to provide an angle adjustment device for iron hands.

[Means for solving problems]

To achieve the above object, the present invention is an iron hand device in which a suction cup is movable back and forth through an iron hand jaw using a power cylinder such as an air cylinder or an oil cylinder, and is supported on the iron hand body. A vertical position holding member is rotatably supported in the vertical direction on a support member that is attached to the support member, a horizontal position holding member is fixed to the vertical position holding member, and an iron hand jyo is rotated horizontally on the horizontal position holding member. The supporting member supported by the iron hand body is provided with a power cylinder such as an air cylinder or an oil cylinder for vertical angle adjustment to vertically rotate the vertical position holding member, and A power cylinder such as an air cylinder or an oil cylinder for horizontal angle adjustment for horizontally rotating the iron hand jig is provided on the horizontal position holding member, and the power cylinder is connected to the operation panel via electrical wiring. It is characterized in that it is operated by an operation button provided on the.

[Effect]

By operating a power cylinder such as an air cylinder or an oil cylinder for vertical angle adjustment that is fixed to a support member supported by the iron hand body, the vertical position holding member rotates in the vertical direction. The vertical angle of the iron hand jyo supported via the horizontal position holding member is adjusted. On the other hand, by operating a power cylinder such as an air cylinder or an oil cylinder for adjusting the horizontal angle fixed to the horizontal position holding member, the iron hand jigyo is rotated in the horizontal direction and the horizontal angle is adjusted.

〔Example〕

Hereinafter, details of the present invention will be described with reference to an embodiment shown in the drawings.

In the figures, reference numeral 3 denotes an iron hand consisting of a support rod 1 and a suction cup 2 for suctioning a workpiece 4. Showing hand jiyo. This iron hand 3 is moved horizontally along a guide rod 6 by driving an air cylinder 5. The air cylinder 5 is supported by an iron hand jaw support member 19 via a bracket 18.

In FIG. 1, reference numeral 8 indicates a support member supported by the iron hand body 7, and this support member 8 is movable up and down by an air cylinder 20. A vertical position holding member 9 is rotatably supported by a pin 10 at the lower end of the support member 8 . A vertical angle adjustment actuator 22 consisting of a power cylinder is fixed to the support member 8 by a bracket 21, and a piston 23 of this actuator 22 is fixed to the opposite side of the pin 10 of the vertical position holding member 9. A horizontal position holding member 13 is fixed to the vertical position holding member 9 . As shown in FIG. 2, this horizontal position holding member 13 is formed with a pin hole and a long hole 17 (not shown), and these holes are provided with a pin 24 and a pin 15 that support the iron hand support member 14. It is supported through insertion. A bracket 25 is fixed to the horizontal position holding member 13, and a horizontal angle adjusting actuator 26 consisting of a power cylinder is fixed to this bracket 25. The piston 27 of the horizontal angle adjustment actuator 26 is connected to the connecting plate 28
