Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a bag feeding mechanism for feeding a plurality of grain storage bags supported at a standby position one by one to a grain filling predetermined position, The present invention relates to an automatic grain bagging apparatus provided with a bag cradle for receiving and forcibly swinging a grain storage bag on a downward inclined surface toward the bag feeding direction.

[Conventional technology]

Conventionally, when the bag at the standby position is fed to the grain filling predetermined position, the lower part of the bag is brought into contact with the upper end of the bag cradle to regulate the movement toward the grain filling predetermined position, and In the middle of filling, the lower part of the bag receives the moving force due to the weight of the grains stored up to that time, moves over the upper end of the bag holder and moves to a predetermined grain filling position. As shown in FIG. 8, when the lower part of the bag (3) is in contact with the bag receiving base (11) and is bent from the beginning of filling, the bent portion (3a) to the lower end is This is to prevent this from filling the grain. (For example, Japanese Utility Model Laid-Open No. 62-115304).

[Problems to be solved by the device]

In the case of adopting such a configuration, when the lower part of the filling bag crosses over the upper end of the bag cradle during the filling and moves to the grain filling predetermined position, if the remaining number of the standby bag is 2 to 3 bags,
In some cases, the lower part of the standby bag, which is located adjacent to and immediately after the bag being filled, also exceeds the upper part of the bag holder and is fed to the grain filling predetermined position in a state of being in integral contact with the lower part of the filling bag. . Then, it is obvious that the grain storage bag delivered onto the bag receiving base (11) causes insufficient filling as shown in FIG. 8, which is not preferable.

In addition, in this case, if the wind blows, the lower part of the bag may come off from the bag cradle, and the forced swinging force cannot be applied when filling the removed bag, which reduces the filling efficiency. Sometimes it came.

It is an object of the present invention to provide a new mechanism that can be used to favorably separate a subsequent bag from a filling bag.

[Means for Solving the Problems]

The characteristic configuration according to the present invention is to provide a bag feeding mechanism for feeding a plurality of grain storage bags supported at the standby position one by one to a predetermined grain filling position, and to direct the grain storage bags during grain filling in the bag feeding direction. In an automatic grain bagging machine equipped with a bag cradle for receiving and forcibly swinging on the descending inclined surface of the, when the bag at the standby position is fed to the grain filling predetermined position, it is moved to the grain filling predetermined position under the bag. Regulate the transition of
When the filling amount in the bag reaches a predetermined amount, a bag feeding restriction device that allows the lower part of the bag to climb over is positioned above the upper end of the bag cradle so as to abut the upper and lower intermediate portions of the peripheral surface of the standby bag. The feed-out restricting device is composed of a rotating member that is rotatable around the horizontal axis that intersects the bag feeding direction of the grain storage bag.

[Action]

In other words, by specializing it as a bag feeding restriction device, the installation height of this restriction device can be set to a position higher than the upper end of the bag cradle, so that the lower part of the filling bag overcomes this restriction device during filling. When moving to a predetermined grain filling position, the lower portion of the succeeding bag is also lifted with the lower portion of the filling bag to be moved. However, since the regulating tool is located higher than the upper end of the bag pedestal, the contact friction force required to lift the bag together with the filling bag is not reached until the lower part of the succeeding bag reaches the height of the regulating tool. It becomes weaker and the lower part of the succeeding bag cannot hang over the restraint and hangs down.

Further, due to the high position of the restricting tool, the standby bag does not get over the restricting tool even if the wind blows to some extent, and is strong against the wind.

In addition, since the restricting tool that comes into contact with the storage bag is composed of a rotatable member that can rotate freely, the lower portion of the filling bag easily crosses over the restricting tool, even though the restricting tool is placed at a higher position than before. Therefore, there is no inconvenience that the standby bag is not delivered to the proper position.

[Effect of device]

Therefore, by setting the mounting height of the restraint device to a position higher than the upper end of the bag cradle, that is, the height at which it contacts the upper and lower middle portions of the bag peripheral surface of the standby bag, it is possible to ensure that it is on the bag cradle below the succeeding bag. Can be prevented, and the standby bag can surely get over the restraint tool. As shown in FIG. 8, the lower end of the bag (3) is not filled with grains, or the bag holder (11) ) It is possible to prevent it from coming off from above and the forced swing not working.
