In the conventional palletizing hand 1, when the bag 4 held by the pawls 5a, 5b for preventing displacement and the claws 6a, 6b for holding is transferred, the holding direction of the bag 4 The protrusion in the direction (arrows A 1 , A 2 in FIG. 6) perpendicular to the direction of movement is caused by the frictional force caused by the pressing force of the positional shift prevention claws 5 a, 5 b and the bag 4.
Is prevented by the frictional force between the holding claws 6a and 6b due to the weight of the holding members.

As described above in detail with the embodiments of the present invention, according to the robot hand of the first invention,
In a robot hand provided with a position-shift preventing claw for holding both sides of the work and a holding claw for holding the work from both sides, the work held by the position-shift preventing claw and the holding claw is viewed from above. By pressing with the holding plate, the holding plate and the holding claw are sandwiched vertically, so that the friction force between the holding claw and the work increases, so large acceleration and deceleration during transfer of the work is performed. Even if added, the work can be prevented from jumping out.

According to the robot hand of the second aspect of the present invention, in the robot hand provided with the claw for preventing displacement and holding the work from both sides, and the claw for holding the work from both sides, the claw for preventing displacement is provided. The work held by the holding claws and the holding claws is configured to be suppressed by the protrusion preventing plate from both sides in the direction perpendicular to the holding direction, so that even if a large acceleration or deceleration is applied during the transfer of the work, the protrusion preventing plate is used. The work can be prevented from jumping out. In addition, in the first invention, it is necessary to consider that an excessive load is not applied to the holding claws or the like. However, in the second invention, it is possible to easily prevent the work from jumping out without such consideration.
