Description

[Detailed Description of the Invention] The present invention relates to a loading/unloading device for handling chemicals, bacteria, and other dangerous substances that cannot be directly touched or approached by workers.

In conventional loading and unloading machines, a drive source such as a motor is often located close to the gripping, movable, and moving mechanisms of the machine. However, if you are handling dangerous objects that cannot be touched or approached more than a certain distance, such as containers, or if the operation site is widely contaminated due to an accident and the operator cannot enter, it may be relatively malfunctioning. There was a problem in that it was impossible to inspect, adjust, repair, replace parts, etc. on drive sources such as motors, which are prone to causing damage, making them unusable. The present invention aims to provide a loading/unloading device for handling dangerous materials based on a new idea that solves these problems.

The present invention will be explained below based on examples.

The embodiment is a device for inserting and storing a container 16 containing a dangerous substance into a storage hole 19 of a transport container 18 installed under a floor 17, and for taking out the container 16 from the storage hole. A rotating post 1 is attached at a predetermined distance from the underfloor space that accommodates the transport container 18, an elevating carriage 2 is attached to the rotating post, a horizontal arm 3 is provided protruding from the elevating carriage, and it is movable to the horizontal arm. A holding device 5 is swingably suspended from the lower part of the carrier via a suspension arm 20. The drive source of this device is electric motors 6, 6', 6'', 6, all of which are
A long ball screw 7 and two torque shafts 8 and 9 are disposed at the bottom of the swing post 1, and are installed vertically close to the swing post 1. The lower end of the ball screw 7 is interlocked with the electric motor 6, and the upper end is screwed into the main body of the elevating carriage 2.
Also, the lower ends of the torque shafts 8, 9 are connected to the electric motors 6',
6″ and a bevel gear 12 above.
13 is fixed. Further, torque shafts 10 and 11 are horizontally suspended on the horizontal arm 3, and bevel gears 14 and 15 are fixed to the tips on the post side, and mesh with the bevel gears 12 and 13 of the torque shafts 8 and 9. Furthermore, one torque shaft 10 is threadedly engaged with the main body of the carrier 4 at a threaded portion 21, and the other torque shaft 11 has a
A gear mechanism 23 is attached that converts the rotation of the torque shaft into lifting and lowering of the operation suspension arm 22 of the gripping device 5. The gripping device 5 includes an operating suspension arm 2
A chucking arm 24 that opens and closes with a claw is attached. Furthermore, 25 in the figure is the turning post 1.
26 is a rotating seal, 2 is a large gear driven by an electric motor 6, and 26 is a rotating seal.
7 is a safety shield, 28 is a base, and 29 is a lifting guide rail for the lifting carriage 2.

In this embodiment, the elevating carriage 2 is raised and lowered by operating the electric motor 6 to rotate a ball screw 7, and the rotation of the ball screw causes the elevating carriage 2 screwed therewith to be raised and lowered. Further, when the electric motor 6 is operated, the turning post 1 can be turned by the engagement of a large gear 25 with a gear attached to the drive shaft of the electric motor. Further, horizontal movement of the carrier 4 along the horizontal arm 3 is achieved by operating the electric motor 6', which rotates the torque shaft 8, and the rotation is transmitted to the torque shaft 10 via the bevel gears 12, 14. The rotation of the torque shaft is converted into horizontal movement of the carrier 4 by the threaded portion 21 with the carrier 4, allowing the carrier 4 to freely move horizontally from side to side. Further, the opening/closing operation of the claws of the chucking arm 24 is performed by operating the electric motor 6''. When the electric motor 6'' is operated, the torque shaft 9 rotates, and the torque shaft 9 rotates through the bevel gears 13 and 15 to horizontally rotate the chuck. The torque shaft 11 of the arm 3 is rotated, and the rotation of the torque shaft is converted by the gear mechanism 23 into the vertical movement of the operating suspension arm 22, and the operating suspension arm is linked to this lower end by moving up and down. The chucking arm 24 is moved to open and close the claws. As described above, the electric motor 6 raises and lowers the elevating carriage 2, the electric motor 6' moves the carrier 4 horizontally, the electric motor 6'' opens and closes the claws of the chucking arm 24, and the electric motor 6' moves the carrier 4 horizontally. The motor 6 provides the entire turning motion, and the electric motors 6 to 6
By the operation 6, the gripping device can be moved up and down, left and right, rotated, and opened and closed with its claws.

As described above, according to the present invention, by having the above-mentioned structure, the gripping device can be moved up and down, left and right, rotated, and released from the grip, and not only can cargo be quickly and easily carried in and out, but also can be repaired in case of failure, inspection, or repair. By gathering the electric motors 6, 6', 6'', and 6, which are the drive sources that have a high degree of You can get the same effect.
