Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for suspending and supporting a pair of left and right bags through eyelets provided at the left and right ends of the opening of a grain storage bag equipped with a zipper at the opening. The grain storage bag is inserted and supported by the rotating shaft, and the pushed-out tool elastically presses the grain storage bag inserted and supported toward the leading end of the rotating shaft. The present invention relates to an automatic grain bagging device configured to forcibly transfer grain storage bags to the tip side of a rotating shaft and sequentially pay them out below a grain discharge port by rotation of the grain storage bag.

[Conventional technology]

As shown in FIG. 4, this type of extrusion tool (028) has a contact surface that elastically presses the insertion portion of the grain storage bag (03) supported by the rotation shaft (04), and a rotation shaft threaded portion (014). The eyelet is formed on an inclined surface along the direction of the lead angle inclination, and the suppressing action of the inclined surface corrects the position of the rotating shaft insertion part in accordance with the lead angle of the threaded part, and allows the eyelet to smoothly engage the threaded part. It was designed to be carried out by

[Problem that the invention seeks to solve]

However, even though the grain storage bag is constructed such that the rotation shaft insertion portion is inclined, the bag thickness at this portion is reduced due to the presence of one end of the fastener located near the insertion portion of the grain storage bag. If the bag is thicker than the thickness of the shaft insertion part and the number of layers at this hanging position increases, the bag located on the threaded part side will not be able to maintain the desired tilted posture, and the bag will not be able to reach the threaded part. Sometimes I couldn't bite properly.

The point is to provide something that can be done more smoothly.

[Failure to solve the problem]

The characteristic configuration of the present invention is that a protrusion is provided on the side of the eyelet to abut and restrict the rotating shaft insertion portions of grain storage bag groups superimposed in the front and back in parallel with each other, and its effects are as follows. It is as follows.

[For production]

Due to the abutment regulating action of the protrusion, the insertion parts of the bag group rotating shafts, which are about to change their posture due to the influence of one end of the fastener, can be forced to be parallel to each other, so the bag group can be maintained in the desired posture. This allows for smooth engagement with the threaded part of the rotating shaft.

〔Effect of the invention〕

As a result, it has become possible to provide a useful automatic grain bagging device with a simple structural addition of just the provision of a protrusion, without any other major modification.

The bag (3) is configured to be automatically opened below the discharge port (5) by cooperation with the threaded portion Q4i (141) having a lead angle.

The rotation shaft (4), +4+, is such that the one on the - side can freely swing near and far with respect to the other one around the base end vertical axis (a),
In addition, it is swing-biased in the reaching direction via a spring 01), and is configured so that it can be stretched without sagging with respect to the inserted and supported bag (3).

As shown in FIG. 2, the grain automatic filling mechanism (2) is described in detail. A movable discharge port (5A) that moves downward is provided below the grain discharge port (5), and a movable discharge port (5A) is provided below the grain discharge port (5). The shutter members (l0A) and (IOA) that can be vertically pivoted around # The shutter member (IOA) is configured to be in a state where it can be moved in a position formed in a shape.

(IOA) is automatically swung to the open position in accordance with the downward movement of the movable discharge port (5A), thereby widening the bag opening +1) of the storage bag (3) while The outlet (5A) is inserted into the bag (3), and the shutter member (IOA), based on the bag (3) open position sensing activation of the limit switch (S6) attached to the bottom surface of the shutter member (IOA), The structure is such that the first sliding shutter (7) located above the shutter member (IOA), cIOA) is placed in an open position and grain is automatically filled.

To explain the drive mechanism for the above in detail, a drive chain (19) stretched parallel to the bag (3) is connected to a drive chain (19) that swings a lever that raises and lowers the movable discharge port (5A). 1 arm (I6), a first arm η for operating the lever (7a) for opening and closing the first shutter (7), and a zipper-closing slider (9) equipped on the opening edge of the storage bag (3). ) and move in the zipper closing direction are protruding locking arms (l@), respectively. These three arms net, o7) and oa are chains (1 The first rotational movement of @ from the first position to the second position causes the first arm to lower the lift operation lever (5a) and the second arm (17) to open the opening and closing operation lever (7a). The closing operation of the opening/closing operation lever (7a) by the second arm (I7) is performed so that The chain is attached to the chain (l) so that the lifting operation of the lifting operation (5a) by the first arm and the closing operation of the slider (9) by the locking arm α are performed in the order described.
