1 to 3 show a trolley for moving a packaging material and the like according to an embodiment of the present invention. FIG. 1 is a front view showing a state in which the packaging material and the like are being gripped, and FIG. FIG. 3 is a front view showing a state in which the user is not gripped, and FIG. The base 101 has a driven wheel 1
02 is rotatably supported, and the drive wheel 104 and the steering wheel 103 are connected. On the base 101, several balance weights 105 are stacked and mounted. By adjusting the balance weight 105, even if a heavy packaging material or the like is gripped, the movable cart of the packaging material or the like is prevented from tilting or falling. On the left side of the base is a work board 1
08 is attached. Lifter 1 on the left side of the base
10 stands upright. A push handle 107 is mounted on the left side of the lifter 110. The second horizontal arm 120 (second arm) moves up and down along the lifter 110. In the second horizontal arm 120, a linear motion guide is attached to a horizontal arm that projects horizontally to the right, and a turning fulcrum 121 is attached to a linear motion block that smoothly moves linearly along the linear motion guide. ing. The turning fulcrum 121 is provided with a shaft projecting vertically downward, and the vicinity of the left side of the first horizontal arm 130 (first arm) is rotatably supported on this shaft. Therefore, the first horizontal arm 130 can freely rotate in a horizontal plane. A shaft protruding vertically downward is attached to the right end of the first horizontal arm 130, and a vertical member 140 is attached to the shaft extending vertically downward. To that end, the vertical member 140 is rotatable about an axis. A gripper 150 is pivotally supported near the lower end of the vertical member 140, and a rear end of the gripper 150 is connected to a swing cylinder 141 attached to the vertical member 140. Therefore, by driving the rod of the swing cylinder 141 to expand and contract, the gripper 150 can reversibly change the swing attitude from the horizontal attitude to the vertical attitude. At an outer position of the gripper 150, an outer surface clamp 142 supported by a base end of the gripper is supported.
With the change of the posture of 0, the posture of the outer surface clamp 142 can also be changed. An operation box 144 and an operation handle 143 are attached to the vertical member 140.

Next, the gripper 150 of the mobile trolley according to the embodiment will be described in detail with reference to FIGS. The tip 152 has a shape in which a truncated cone and a cylinder are combined, and a cylinder shaft 153 having a common axis is coupled to the cylinder portion. A cylindrical shaft 153 is inserted into the hollow holes of the two ring-shaped rubber members 151, and a metal washer is interposed between the rubber members 151. The washer on the front side is in contact with the frame of the vertical member, and the cylindrical shaft 153 passes through a hole in the frame and is connected to a gripper drive cylinder 154 mounted on the back side of the frame. When the gripper drive cylinder 154 is extended, the tip 152 extends forward, and the diameter of the rubber material 151 becomes the original size and is reduced (see FIG. 8). On the other hand, when the gripper drive cylinder 154 is retracted, the tip 152 moves toward the front, compressing the rubber material 151 in the axial direction and expanding the diameter (see FIG. 9). In this way, the rubber material 151, which is an example of the elastic body, is expanded and contracted. Unlike the present embodiment, it is also possible to change the design so that the rubber material is compressed in the axial direction and expanded by fixing the distal end portion and moving the root portion toward the distal end. Using the gripper having the structure of the present embodiment,
The method of chucking and joining a hollow shaft core hole of a packaging material or the like is as follows. The reduced-diameter gripper is inserted into a shaft hole of a packaging material or the like (see FIG. 5). Gripper tip 152
Has a frusto-conical shape, which facilitates insertion into the hollow core. After insertion, the gripper is expanded to firmly couple the gripper with the packaging material (see FIG. 7). Then, to release the connection, the gripper is again reduced in diameter and then pulled out.

Next, the outer surface clamp will be described with reference to FIGS. The two holding pieces 142 whose inner surfaces have a curved surface corresponding to the curvature of the outer surface such as a packaging material approach or move away along the guide shaft 146. This drive is performed by the holding piece drive cylinder 145. A method for gripping a packaging material or the like using the outer surface clamp having such a structure is as follows. First, the holding piece driving cylinder 145 is extended, and the holding pieces 142 are moved away from each other.
Open the external clamp. At the same time, the diameter of the gripper 150 is reduced, and the gripper 150 is
And the outer surface clamp is positioned around the outside of the packaging material 2 (see FIGS. 4 and 5). Next, the holding piece driving cylinder 145 is contracted, the holding pieces are brought close to each other, the two sides of the packaging material or the like are sandwiched and gripped by the holding pieces, the gripper 150 is expanded, and the gripper 150 is expanded by the gripper 150. Of the shaft hole 201 (see FIGS. 6 and 7)
