Description

  The present invention is provided with a force sensor in the hand part, holds and holds the cargo handling object by the hand part attached to the hand, and handles the cargo handling object according to increase / decrease of the electric signal of the force sensor attached to the operator's hand. The present invention relates to a hand portion of a material handling machine to be moved up and down.

  Prior art will be described. The hand part of FIG. 2 of the cited document 1 describes that the glove-like hand part 6 is attached to the connector 7, and the band and glove that look like a ring are fixed and integrated with the hand part 6. is there. It is a configuration in which only the gloves cannot be removed. Therefore, it took time and effort to put in and out of the glove-like thing, and the degree of freedom of the hand was small.

  Although Cited Document 2 is a mittens-type glove, it takes time to put in and out of the glove.

  Cited Document 3 is effective for a cargo item having a handle in a box. However, when filling out a slip, there are times when the hand is pulled out from the hand unit during the work, the work is interrupted, and the work starts immediately. At that time, the operation of putting in and out of the support belt was troublesome. The hand parts of Cited Documents 1 to 3 use force sensors and the lifting control is smooth, but all the hand parts are cumbersome to put in and out of the hands, the configuration is not simple, and the degree of freedom of the whole hand is limited. It was.

  In Cited Document 4, the tip of the hand portion is L-shaped, and the cargo handling object is held by narrowing the L-shaped claw with an opening prevention tool. However, Cited Document 4 is suitable for holding the cardboard box obliquely with L-shaped claws, and cannot be operated with the sensation of hands and fingertips. Further, in the cited document 4, the cargo handling device ascending / descending command unit is not provided with a force sensor, and the configuration including the raising / lowering switch is not simple.

  The problem to be solved is that the configuration is not simple, and it is troublesome to put the hand in and out of the hand part.

  The present invention has a right hand ring part and a left hand ring part or ring part in the hand part, the overall configuration is simple, and the right hand ring part and the left hand ring part or ring part are most easily put in and out of the hand. Main features.

  The hand part of the material handling machine of the present invention has a simple configuration and is easy to put in and out. In addition, the wrist is not painful because the degree of freedom of the wrist is greater both in the lower and upper positions than in the glove type. In addition, when writing a slip during work, it is possible to smoothly remove the hand from the hand portion. It is also possible to hold a writing instrument with a finger while putting a hand in the ring part for the right hand and the ring part for the left hand or the ring part. Since it is a simple configuration, there is an advantage that it is easy for the operator to handle. The cargo handling equipment is a cargo handling machine that assumes up to about 30 kg, and grips and supports the cargo handling with the gripping force of the hand, but if it is up to about 30 kg, it can be held and supported without problems because it uses both hands. Since the lifting force is performed by the lifting mechanism of the cargo handling equipment, the burden on the operator's waist is small and labor saving is achieved.
