Further, as shown in FIGS. 2 and 3, the trolley conveyor 2 has a power rail 9 and a free rail 10 disposed below the power rail 9. A driven power chain 11 is suspended, and a front trolley 12 and a rear trolley 13 are guided on the free rail 10. Furthermore, the power chain 11 has rollers 15 guided by the rail 9 at predetermined intervals, and has hook pieces 16 projecting downward. Further, the front trolley 12 has a trolley main body 17, and the main body 17 has a rail 1.
A roller 19 guided by a roller 19 is rotatably supported, and a main door 20 and a lever 20 and a lever holding door 21 are provided to protrude upward. The actuating piece 22 is swingably supported. In the main dock 20, the chain 11 is caught on the piece 16 in the normal state, but the main dock 20 is interlocked with the actuating piece 22, and when the actuating piece 22 swings upward, Lord Do, Ri 20
Insert the hook so that it comes off from piece 16. Also, Ba,
The holding lever 21 is designed to be able to rotate only forward, and prevents the front trolley 12 from moving beyond the hook 16 due to inertia or the like. Also, the rear trolley 1

On the other hand, in the empty hanger storage area 3, the free rail 1° is branched into two by a branching means and installed in parallel at a predetermined distance apart, and the power rail 9 is (6) on one of the free rails 10a. It is installed only at the top of the drawing. Therefore, the front trolley 12 is guided by one free rail 10a and pulled by the common chain 11, and the rear trolley 13 is guided by the other free rail 10a.
You will be guided to b. As a result, the hanger 28 is suspended across the two free rails 10m and 10b, and runs and waits at an angle of about 45 degrees with respect to the rail running direction.

Furthermore, the empty container supply section 4 is constructed by merging the free rails 10 from the empty hanger storage section 3 into one rail by a merging means, and stopping the travel of the hanger 28 due to strikes, pars, etc. Then, in the empty container supply section 4, an operator attaches the empty container taken out from the empty container storage area 8 to the hanger 28 using an inlet bag opening device or by automatic means such as a robot.

Furthermore, as shown in detail in FIG. 4, the filling section 5 includes two turntables 33&, each having a free rail 10.

It is turned 90 degrees by 33b and is branched into two, with the front trolley 12 being guided by one free rail 10c and the rear trolley 13 being guided by the other free rail 10d. Furthermore, power chains 11 are disposed above these two free rails 10c and 10d, and the chain 11a on the other free rail 10d is disposed low, so that it cannot be caught at a normal chain height. The front trolley 12 and the rear trolley 13 are both driven by the engagement of the auxiliary lever 27 which cannot be hooked onto the piece 16, so that the front trolley 28 is moved laterally, i.e. out of the normal direction of travel. It runs in the orthogonal direction. Further, a hopper 35 for supplying powder and granules is arranged above the middle part of the filling section 5 consisting of the two parallel rails 10c and 10d, and the hopper 35 is arranged so as to stop at the holler 235 position A-A. The hopper 35 is also provided with a discharge port that can be moved up and down so that it can be inserted into the cylindrical portion 29- of the hanger 28. Further, the discharge port portion is configured to open as the discharge port moves downward, and to lift upward when the shutter is closed so that the discharge port does not interfere with the hanger 28.

In addition, after the two parallel rails 10c and 10d are once merged from the filling section 5 by the merging means,
