Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a bag feeding mechanism for feeding a grain storage bag from a bag standby position to a grain filling predetermined position, and a filling bag filled with grains by the grain filling mechanism. The present invention relates to a grain bag filling device which is provided with a bag releasing mechanism for releasing and a bag receiving base for receiving and forcibly rocking a filled bag at a predetermined grain filling position.

[Conventional technology]

Conventionally, when the bag at the bag standby position is fed to the grain filling predetermined position as shown in FIG. The lower part of the bag contacts the side of the bag standby position on the bag cradle to regulate the movement toward the grain filling predetermined position, and while the grain filling progresses, the weight of the grain accumulated until then causes The lower part was configured to receive the moving force, go over the upper end of the bag holder, and move to the grain filling predetermined position. As shown in FIG. 5, when the lower portion of the bag (3) is in contact with the bag receiving base (11) and is bent from the beginning of filling, the bent portion (3
This is to prevent this because grain is not filled from a) to the bottom. (For example, actual development Sho 62-115304
(See FIG. 1 of the publication).

[Problems to be solved by the invention]

In the case of adopting such a configuration, since the lower portion of the filling bag fed to the grain filling predetermined position only at the upper end at the bag standby position side end of the bag receiving stand is position-controlled to the standby position, the standby bag is If there are many standby bags, there will be no problem, but if the number of standby bags becomes a few, such as two or three, the unfilled bags will be fed out on the bag cradle due to wind, etc., and will bend as shown in Fig. 5. If the bag is filled with some parts left, or if the lower part of the bag is moved out of the bag cradle by the wind and is filled as it is, the forced rocking action does not work on the bag being filled at all. Therefore, there was a case that the filling was insufficient.

An object of the present invention is to provide a bag cradle with a simple mechanism so that a bag before being filled will not be fed to a predetermined grain filling position by wind or the like.

[Means for solving problems]

The feature of the present invention is that it is provided on the wall surface on the hand side in the bag feeding direction from the bag standby position and the lower end of the grain storage bag fed to the grain filling predetermined position is brought into contact with the lower end of the bag. An elastic pressing body for regulating the position is provided at the end of the bag receiving stand on the side of the bag standby position, and when this elastic pressing body reaches a predetermined amount in the middle of filling, the lower end portion of the storing bag itself due to its own weight. It has a structure that allows it to move over the upper surface of the bag cradle, and its action and effect are as follows.

[Action]

When the swinging arm biased toward the standby bag shown in FIGS. 1 and 2 is used as the elastic pressing body (15) as in the characteristic configuration, as shown in FIG. 1, the standby bag (3 ) Is large, the elastic pressing body (15) is swung forward by the total weight of the standby bag, and as shown in FIG. Even when the number of standby bags (3) is small, the standby bag can be sandwiched between the wall surface (22) and the standby bag (3) so that the standby bag cannot be pushed up even if wind blows. . Moreover, even in the above-mentioned sandwiched state, since the standby bag is only held in the standby posture by the urging force of the elastic pressing body, when the filling reaches a predetermined amount as in the characteristic configuration. However, the tensile force applied to the lower end of the bag cannot be resisted, and the elastic pressing body is elastically displaced to allow the lower end of the bag to move to the upper surface of the bag receiving base.

[Effect of device]

Therefore, irrespective of the number of bags at the standby position, it is possible to prevent transfer of bags to the upper surface of the bag cradle in the unfilled state, and eliminate insufficient filling due to inability to swing. In addition to the above, the structure for that purpose only needs to additionally include the elastic pressing body.
