The plug lifting fluid pressure cylinder 213 is fixed by appropriate supporting means (not shown).

Next, with reference to FIGS. 7-9, a container supply operation is demonstrated.

In FIG. 7A, the front and rear body 91 is located at the exchange station S1. The lifting body 92 is in the upper limit, and the left and right fuselage 93 is in the left upper limit. In this state, the roller 143 is in contact with the left end of the cam surface 164, and the front and rear chuck 94 is in a spaced state. The second chuck member 152 protrudes from the first chuck member 151 to the left side, and a gap is formed between the tips of both chuck members 151 and 152.

In this state, as shown in Fig. 7 (b), when the container 11 is loaded to the exchange position by the container extraction suction member 44, the second chuck member 152 is moved to the right, so that both chucks are moved. The gap between the ends of the members 151 and 152 is closed. As a result, the front and rear ends of the opening forming edge portion 28 of the container 11 are fixed by the chuck 94. As shown in FIG.7 (c), the container extraction | suction adsorption member 44 is removed in order to pick up the next container 11. As shown in FIG.

In FIG. 8A, the front and rear fuselage 91 moved from the container exchange station S1 to the container supply station S2 is shown. Subsequently, as shown in Fig. 8 (b), the left side adsorption member 98 for opening the container is moved to the right side, and the both opening members 95 and 98 for opening the container are adsorbed. Thereby, the front-back direction center part of the container 11 is attracted by the both adsorption members 95 and 98. As shown in FIG. As shown in Fig. 8 (c), when both of the adsorption members 95 and 98 are moved in the direction away from each other, and thus the left and right body 93 are moved to the right, the roller 143 moves the cam surface 164. While rotating, it is moved to the right. Accordingly, both chucks 94 are moved in a direction approaching each other. As a result, the opening forming edge portion 28 is opened. Both adsorption members 95 and 98 are removed by adsorption and leave as they are.

Fig. 9A shows the state shown in Fig. 8C as viewed from the rear. When the opening forming edge portion 28 is opened, as shown in Fig. 9B, the piston rod 214 of the plug lifting fluid pressure cylinder 213 protrudes, and the plug 201 waiting at the upper limit. Is lowered simultaneously with the contact plate 212. In the process of lowering the contact plate 212, the lowering of the plug 201 is stopped by the contact plate 212 contacting the engagement plate 123. At this time, the plug 201 is fitted into the opened opening forming edge portion 28 so that the opening is closed. When pressure air is supplied to the air passage 203, the entire container is expanded and the container 11 is opened.

When the plug 201 is inserted into the opening forming edge portion 28, the opening of the opening forming edge portion 28 initially has a shape similar to an ellipse, but as the plug 201 is inserted into the opening forming edge portion 28, The ellipse is deformed to be circular by being opened by being pressed by the plug 201. The opening of the opening forming edge portion 28 becomes circular while the inner surface of the opening forming edge portion 28 is in contact with the plug 201 outer surface over its entire length in the circumferential direction thereof, but in this state, the However, the plug 201 is forcibly pushed into the opening forming edge 28 so that the opening forming edge 28 is taut. As a result, air is hard to leak between the container opening edge 28 and the plug 201. To this end, the chuck 94 chucks the lower portion at the contact of the container opening edge 28 with respect to the plug 201.

Next, as shown in FIG.9 (c), the lifting body 92 is lowered. In this case, the chuck 94 is lowered together with the lifting body 92, the container 11 is lowered while being fixed by the chuck 94, and is held by the holder 51. The engagement plate 123 is also lowered as the lifting member 92 descends, while the piston rod 214 of the plug lifting hydraulic cylinder 213 is pressed to protrude, and the contact plate 212 is lowered. ) Is lowered together with the plug 201 in contact with the engagement plate 123. Therefore, the plug 201 is lowered while being inserted into the opening of the container 11. As a result, the container 11 is held in the holder 51 in an open state.

When the container 11 is held by the holder 51, the supply of pressure air is stopped, the chuck of the container 11 by the chuck 94 is released, the plug 201 is raised, and the lifting body 92 is raised. Raise). The front and rear body 91 is moved from the supply station S2 to the exchange station S1, and the chuck 94 is returned to the open state to prepare for the supply of the next container.

When the holder 51 holding the container 11 is taken out from the supply station S2, and the empty holder 51 is brought into the supply station S2, the container supply operation in one cycle is completed.

In the above, a fluid pressure cylinder is used as a driving source of the operation means, the plug and the lifting means, but it is naturally conceivable to use a general driving source such as a motor instead.

According to the present invention, there is provided a bag-type container supplying device capable of reliably supplying a container to a holder, and capable of reliably opening a container even without the troublesome work of releasing the container in advance.
