The support 1 has a rectangular cross section and is disposed such that its longitudinal surface 1a (vertical direction in FIG. 1) directly faces a position 2a of the bottle stand 2 where the container is placed.

Reference numerals 3 and 4 designate a pair of gripper members, each of which is comprised of a pair of upper and lower plates 3a, 3b, 4a, 4b connected via spacers 5, 6, 7, 8. The gripper members 3 and 4 are provided with grooves 3d and 4d cut out in a direction perpendicular to the opposing surfaces 3c and 4c, and the support column 1 is fitted into these grooves 3d and 4d. It matches.
Further, a support plate 9 is fixed to the upper part of the support column 1, and the upper plates 3a and 4a of both gripper members 3 and 4 are supported by this support plate 9. Therefore,
Both gripper members 3 and 4 are supported by a support plate 9, and are guided by longitudinal surfaces (guide surfaces) 1a and 1b of the column 1 fitted in grooves 3d and 4d, and are moved in parallel toward or away from each other. It is now possible to do so. Approximately arc-shaped notches 3e and 4e forming article support portions are formed on opposing surfaces of the tip ends of both gripper members 3 and 4 extending toward the container placement position 2a. By moving the notches 4 closer to each other or farther apart, the interval between the two notches 3e and 4e can be set to an arbitrary size.

10 is a guide plate arranged on both gripper members 3, 4. This guide plate 10 has a hole 10a formed in the center thereof, and a nut 11 that is disposed above and passes through this hole 10a is inserted into the support column 1.
It is designed to be fixed by screwing onto the top surface of the. The guide plate 10 has a substantially rectangular shape, and the four sides 10b, 10c, 10d, and 10e have different distances from the center ₀₁ of the support column 1, respectively. Then, two fitting holes 10f, 1 are provided on each side.
0f, 10g, 10g, 10h, 10h, 10
i, 10i are formed, and these respective sets of fitting holes 10f, 10f, 10g, 10g, 10h, 1
The distances between 0h, 10i, and 10i are different. In this embodiment, the fitting hole 1 is formed on the side 10b having the smallest distance from the center ₀₁ of the support 1.
The distance between 0f and 10f is the largest, and as the distance from the center ₀₁ of each side increases, the distance between the fitting holes provided on each side becomes smaller. On the other hand, one pin 12, 13 is provided on each of the gripper members 3, 4. Then, from the center 0 ₁ of the support 1, each set of fitting holes 10f, 10f, 10g, 10g, 10h, 10
The distances to the lines that connect h, 10i, and 10i, respectively, and the distances to the lines that connect the two pins 12 and 13 are all equal. By arranging both pins 12 and 13 in the fitting hole 1 of which pair
0f, 10f, 10g, 10g, 10h, 10
h, 10i, and 10i can also be fitted.

In the article holding device configured as described above, when holding a large container, the guide plate 10 connects the edge 10b of the gripper members 3, 4 closest to the center ₀₁ of the support 1, as shown in FIG. Notch 3e, 4
Both gripper members 3,
4 are moved in a direction away from each other, and when the distance between the pins 12 and 13 of the gripper members 3 and 4 matches the distance between the fitting holes 10f and 10f of the guide plate 10, they are respectively fitted and fixed by nuts 11. . In this state, from the center ₀₂ of the container on the bottle stand 2, the notches 3e of the gripper members 3, 4,
The distance to the tip of the guide plate 4e and the distance to the side 10b on the notch side of the guide plate 10 are almost the same, and it is constituted by both these notches 3e, 4e and one side 10b of the guide plate 10. Articles such as containers are stably held within the article receiving section 14.

Next, when switching to a smaller container, loosen the nut 11, lift the guide plate 10, remove it from the pins 12 and 13, rotate it, and move it a predetermined distance from the center 0 ₁ of the support column 1. The side 10d (shown by imaginary lines in Figure 1) with
e, 4e side. Next, bring both gripper members 3 and 4 close together, match the distance between both pins 12 and 13 to the distance between fitting holes 10h and 10h on side 10d, and insert pins 12 and 13 into holes 10h and 10h. Tighten the nut 11. In this way, by bringing both the gripper members 3 and 4 close to each other and rotating the guide plate 10 to direct one side 10d of the column 1 having a large distance from the center ₀₁ toward the notches 3e and 4e, these three The size of the article receiving section 14 constituted by the members 3e, 4e, and 10d can be reduced. Also, the center of support 1 is 0 ₁
The fitting holes 10f, 10f, 10 of each set are arranged according to the distance from the side to each side 10b, 10c, 10d, 10e.
Since the distance between g, 10g, 10h, 10h, 10i, and 10i is set, the gripper members 3 and 4
Positioning in the width direction (vertical direction in FIG. 1) is automatically performed.

As described above, the size of the part that holds the article can be changed by the relative movement of the pair of gripper members 3 and 4 and the rotation of the guide plate 10, so special parts are prepared according to each article. This is not necessary, and the time required for switching can also be significantly reduced.

In the above embodiment, the guide plate 10 basically has a rectangular shape, but it goes without saying that the guide plate 10 is not limited to this and other polygonal shapes may be used. Moreover, the shape of the article support part is not limited to the above-mentioned arcuate notch, but can also be formed by a straight line or other curved line.
