It is rotatably supported by.

  That is, in the present embodiment, a square bar-shaped weight 31 for applying a biasing force is coupled to the outer surface of the upper end portion of each opening / closing plate 3 at a right angle. The end portions of the weights 31 connected to the opening / closing plate 3 are rotatably attached to the support arm 22 via the pins 32 so that the opening / closing plate 3 is rotatable.

  The weight 31 is positioned substantially in the horizontal direction when the open / close plate 3 is disposed substantially vertically downward (opened state) as shown by the two-dot chain line in FIG. 1 and the left portion in FIG. The load effectively acts as an urging force for the opening / closing plate 3. The opening / closing plate 3 is always given a biasing force by the load of the weight 31 in the direction of the inclined state (closed state) indicated by the solid line in FIG. 1 and the right part in FIG.

  At this time, as shown by a solid line in FIG. 1, the pair of opening / closing plates 3 is adapted to be fitted in a V shape in which each lower end portion has an acute angle in the closed state. And the opening part 10a of the gusset bag 10 is inserted in the front-end | tip part of the opening-and-closing board 3 used as V shape as shown by the dashed-two dotted line in the figure. In the present embodiment, when the opening / closing plate 3 is in the closed state, the distal end portion of the weight 31 abuts against the stopper 33 provided on the support arm 22 so that no extra load is applied to the closed closing plate 3. It is like that.

  As shown in FIG. 4, the gusset bag 10 includes a front surface 11 and a back surface 12 that are formed in a substantially rectangular shape, and a pair of side surfaces 13 that continuously connect the sides of the front and back surfaces 11 and 12. The lower end portions of the surfaces 11, 12, and 13 are sealed by, for example, heat sealing (may be bonded) to form a sealed portion 10b. Both side surfaces 13 are folded in a flat state by being gusseted (valley folded) inward. And the gusset bag 10 is distribute | circulated in the state folded in this way flatly. Moreover, the upper end part of each surface 11, 12, 13 is open | released and becomes the opening part 10a.

  Therefore, in order to manually load the gusset bag 10 with the contents, for example, a large umeboshi P indicated by a two-dot chain line in the figure, the gusset bag 10 is opened by opening the opening 10a of the folded gusset bag 10 widely. After inflating the entire bag 10 into a square tube shape, the dried plum P is put into the bag through the opening 10a.

  On the other hand, in the present embodiment, the folded gusset bag 10 may be in a slightly opened state without opening the opening 10a greatly, and the slightly opened opening 10a is opened and closed in the above-described closed state. It will be inserted into the outside of the lower end of the plate 3. At this time, as shown in FIG. 2, in order to make it easy to insert the opening 10a of the gusset bag 10, the front end of the opening / closing plate 3 is formed in a substantially wedge shape.

  As shown in FIG. 2, a shaping member 5 is disposed at the tip of the slide arm 4 so as to be positioned above the pair of opening and closing plates 3. The shaping member 5 is formed by a hollow tube 52 having a hopper 51 at the top, and the upper end portion of the hollow tube 52 is coupled to the slide arm 4, and the shaping member 5 is wholly attached to the slide arm 4. It can be raised and lowered freely.

  The hollow tube 52 is formed in a rectangular shape whose cross-sectional shape is substantially along the fully opened inside of the gusset bag 10. Then, when the shaping member 5 moves down together with the slide arm 4, as shown on the left side in FIG. 3, the pair of opening and closing plates 3 in which the lower end portion of the hollow tube 52 is closed are pushed open against the urging force. However, it is inserted into the inside of the gusset bag 10. At this time, the lower end of the hollow tube 52 is finally inserted to the vicinity of the bottom of the gusset bag 10.

  Therefore, when the pair of opening and closing plates 3 is pushed open as the shaping member 5 is lowered, the opening 10a of the gusset bag 10 inserted into the lower ends of the opening and closing plates 3 is opened widely, and the hollow tube 52 is opened. Further insertion of the gusset bag 10 allows the gusset bag 10 to be entirely inflated and shaped into a rectangular tube.

  On the other hand, an air cylinder 6 for vertically moving the slide arm 4 is attached to the side surface of the apparatus main body 2. Is bound to.

  Next, by operating the switch of the controller 7 to retract the piston rod 61 of the air cylinder 6, the shaping member 5 descends as shown by the two-dot chain line in FIG. The opening / closing plate 3 is pushed open (see the left side in FIG. 3). As a result, the opening 10a of the gusset bag 10 is greatly opened, and the lower end of the hollow tube 52 is inserted into the gusset bag 10 by further lowering the shaping member 5, and the gusset bag 10 is shaped into a rectangular tube shape. .

  In the stage where the gusset bag 10 is shaped into a rectangular tube shape, that is, in the state where the shaping member 5 is lowered, the dried plum P, which is the contents, is put into the hopper 51. Then, the poured umeboshi P is guided to a loading path 53 formed inside the hopper 51 and the hollow tube 52 and loaded into the bottom of the gusset bag 10. Therefore, the dried plum P can be loaded without contacting the opening 10a of the gusset bag 10, so that the dried plum P can be prevented from being damaged or damaged. Can be prevented.

  Thereafter, the shaping member 5 is lifted by operating the switch to project the piston rod 61 of the air cylinder 6, and accordingly, the hollow tube 52 also comes out of the gusset bag 10 and is detached from the pair of opening / closing plates 3. To return to the initial state. Then, the opening / closing plate 3 is closed by the urging force of the weight 31, and the gusset bag 10 loaded with the umeboshi P in this state can be easily removed from the opening / closing plate 3.

  In addition, after removing the gusset bag 10 from the opening / closing plate 3, the opening 10a is sealed by a sealing means (not shown).

  As described above, according to the content loading device 1 of the present embodiment, the shaping member 5 is lowered while the opening 10a of the gusset bag 10 is inserted into the lower ends of the pair of opening and closing plates 31 in the closed state. By doing so, the pair of opening and closing plates 3 is pushed open, and the gusset bag 10 can be shaped into a rectangular tube shape while the opening 10a of the gusset bag 10 is completely opened. Then, in the state where the gusset bag 10 is shaped, that is, in the state where the lower end portion of the hollow tube 52 is inserted into the gusset bag 10, the umeboshi P can be loaded into the bottom portion of the gusset bag 10 from the charging path 53.

  Therefore, the process of shaping the gusset bag 10 into a rectangular tube shape and the process of loading the contents of the umeboshi P into the gusset bag 10 can be performed at the same time, thereby simplifying the overall device and reducing the cost. can do.

  At this time, since the pair of opening and closing plates 3 are biased in the closing direction, it is not necessary to close the opening and closing plates 3 each time the gusset bag 10 is set, and the workability can be further improved. it can.

  Further, according to the present embodiment, the shaping member 5 is constituted by the hollow tube 52 having the hopper 51 at the upper portion, and the inside of the hopper 51 and the hollow tube 52 is used as the input path 53. The configuration of the charging path 53 can be further simplified.

  At this time, by providing the hopper 51 on the upper part of the hollow tube 52, it becomes easy to put in the umeboshi P which is the contents.
