A front and rear cam 17 having a cam groove 17a carved on its surface is attached to the coaxial lower part of the swing cam 15, and a cam follower 18, which is a second engagement means, slides into the cam groove 17a of the front and rear cam 17. They mesh freely. The cam follower 18 is connected to the pivot shaft 4
At the center of a lever 21, a lever 21 is installed between a shoe 19 that is fitted into the rear part of the sleeve 11 and has a groove carved on its outer periphery, and a shaft (pushing shaft) 20, one end of which will be described later, serves as a fulcrum for its own swing. installed. Of course, a cam follower 22 is interposed between the lever 21 and the groove of the shoe 19, and a pin 2 is interposed between the lever 21 and the pushing shaft 20.
It is supported by 3. Therefore, the pivot shaft 4 is configured to move in the front-back direction by the front-back cam 17, the lever 21, and the like. The pushing shaft 20 is movably provided on the rear side of the box body 3, and one end is rotatably connected to the other end of the lever 21. Reference numeral 25 denotes a pressing member (spring), and this spring 25 is provided between a bushing 24 (described later) inside the box 3 and the pushing shaft 20, so that the hand 6 in the direction of the axis of rotation of the pushing shaft 20 is always Press W in the direction to bring it into close contact with chuck C. Furthermore, 24 is a bush, and this bush 24 has an insertion hole into which the rear end of the pushing shaft 20 is slidably inserted. 24a is an adjustment nut that allows the pushing shaft 20 to be adjusted in the axial direction with respect to the box body 3. After the work W and chuck C are brought into close contact, the lever 21 is subsequently swung using one end of the lever 21 as a fulcrum to relieve the pressing force that brings the work W and chuck C into close contact. That is, one end of the lever 21 (on the pivot shaft 4 side) is used as a fulcrum to prevent the lever 21 from pressing the workpiece W toward the chuck C side with an increased pressing force along the cam groove of the second cam follower 18. The structure is such that moving the lever 21 alleviates excessive pressing force. In addition, since the pushing shaft 20 is movable in the axial direction with respect to the box 3, the position of the fulcrum of the other end of the lever 21 can be changed. In addition,
26 is a camshaft, 27 is a motor for driving the camshaft, 28 and 29 are pulleys, and 30 is a belt.
A dog 31, a detection body 32, etc. for detecting the cam position are provided at the upper end of the camshaft 26.

Further, according to the present invention, after the object to be transported and the gripping body are brought into close contact with each other, the lever is subsequently swung using one end of the lever as a fulcrum to relieve the pressing force that brings the object to be transported and the gripping body into close contact with each other. It becomes possible to do so. That is, by moving the lever using one end of the lever (swivel axis side) as a fulcrum, the lever can prevent the lever from pressing the conveyed object toward the gripping body along the second cam groove with increasing pressing force. This has the effect of alleviating excessive pressing force. Further, according to the present invention, since the shaft body is movable in the axial direction with respect to the main body of the loading/unloading device, the position of the fulcrum of the other end of the lever can be changed. That is, when the axial position of the gripping body is changed, the hand can be easily adjusted to the conveyed object transfer position of the gripping body by adjusting and moving the shaft body in the axial direction.
