Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a pair of eyelets of a grain storage bag in which eyelets for hanging support are attached to both ends in the width direction of the bag near the bag opening. By forcibly transferring the grain storage bags in one direction in the axis direction of the rotation shaft through a threaded portion formed on the rotation shaft for hanging support, the grain storage bags are successively fed out and positioned in parallel under the pesticide discharge port. This invention relates to an automatic grain bagging device.

[Conventional technology]

In this type of automatic bagging device for grains, conventionally, the rotary shaft has a threaded portion on its tip side, a bag standby position portion on the upper side of the threaded portion in the transfer direction, and a bag standby position further on the upper side. A spring biasing force is used to push the inner bag toward the threaded portion, and a push-out tool is provided, which combines this pushing force with the rotating part of the rotating shaft! IFIK allows the eyelet of the bag to engage the starting end of the threaded part, and the engagement effect between this eyelet and the threaded part (
Therefore, the grain was configured to be delivered under the grain outlet (
For example, Utility Model Application No. 59-159647).

[Problem that the invention seeks to solve]

However, the threaded portion is threaded in order to ensure an opening area large enough to insert the movable discharge port into the opening of the bag and carry out the entire bag filling operation for the bag placed under the discharge port. Since the pitch is constant K over the entire length and is relatively large, even if the bag is pushed out toward the threaded part with the extrusion tool, the bag can be smoothly bit into the threaded groove of the eyelet. There were times when it wasn't.

An object of the present invention is to provide a modification of the threaded portion (thus, solving the problems associated with the conventional structure).

[A precautionary measure to resolve the problem]

A characteristic feature of the present invention is that the thread pitch of the threaded portion is continuously set to Sakhalin in the latter half of the bag delivery direction, and its effects are as follows.

[Effect]

In other words, since the thread pitch of the threaded part can be made small in the first half, the eyelet of the waiting bag can be smoothly engaged with this threaded part (the second half). Since the pitch of the parts is large, the opening area of the bag can be secured within a range that does not interfere with the insertion of the movable discharge port.
In addition, since the pitch between the front half and the rear half varies continuously, the bag can be transferred smoothly even in the middle section.

〔Effect of the invention〕

As a result, by simply changing the thread pitch of the threaded part, the button can be made to transfer the bag more reliably and smoothly using the rotating shaft. We were able to provide something useful.

〔Example〕

Below the grain discharge port (5) of the hopper (8) storing grains, a pair of left and right rotation shafts (4), (4) for supporting hanging bags is installed, and on these rotation shafts f4+, +41,
The grain storage bag (3), which has hanging support eyelets f2) Tjz) attached to both ends in the opening width direction near the bag opening fl), is stored and supported, and the eyelets +21,
+21 and the rotation shaft f4) and the threaded portion () of +41 engage with each other, and as the bag (3) rotates, the bag (3) is sent out sequentially at a constant pitch in the direction of the rotation axis (, the eyelet (21, +21) A strip plate-shaped reinforcing material f6r provided on opposite sides of the bag (3) in a continuous state and on opposite sides of the bag (3),
The bag opening (1) is automatically opened by the cooperative action of the fat and the threaded portion having a lead angle in the same direction, and the grain discharge port (6) of the hopper (81) is vertically slid. The movable discharge port (5A) held movably is connected to the opening fi.
This constitutes an automatic grain bagging device mounted on a combine harvester or the like, in which bags (3) K are filled with grains by opening the first shutter (7) while the bag is inserted into the bag (3).

The feeding means for the bag (3) will be explained in detail based on FIGS. 3 and 4. One of the left and right rotation shafts (4), (4) When installing and fixing the protruding frame (b) K that can be retracted horizontally (and this rotating shaft (4)
) is urged in a direction away from the other frame by a compression spring (3) provided between the protruding frame (B) and the stationary frame (To).

4 to constitute the threaded portion +211 and rotate the rotating shafts (4), (4).
There are 3.

Immediately above the rotating shaft [4), +41, a presser frame ■ is placed along the axial direction, and the bag opening +
1) It is installed on the upper edge so that it can be contacted from above, and the left and right presser frames ■, (301) are pivotally supported at the rear fulcrum so that they can swing up and down integrally. This presser frame ■ and the fixed side frame A spring (2) for overcoming the dead point is stretched between the frame (1) and the upper edge of the bag opening (1), and a horizontal state in which it can touch the upper edge of the bag opening, and a state in which it is lifted upward (l'lJ). In addition, a detection limit switch (■) that can be operated by an actuating piece provided on the presser frame (2) is provided near the rear support point of the presser frame (2), so that the presser frame (2) can maintain the vertical position when the presser frame (2) performs the bag pressing function. The limit switch (support) is activated only when in the posture, and the self-cut bag filling switch provided at a separate position is activated to drive the rotary shaft (4) in the forward bag feeding direction.
FIA movement of the rotary shaft (4) in the bag reverse rotation direction is possible only when the presser frame ■ is in a non-lifting position and the automatic switch is set to the above-mentioned position. (This allows the operator to replenish and load the bag onto the rotating shaft (4).

At the front end of the presser frame (■) in the bag feeding direction, an elastically actuated piece is protruded through an opening toward the rotating shaft (4) side. A limit switch (to) is provided to detect upward movement due to contact with the grain outlet (5), and is configured to detect when the bag (3) is fed out below the grain outlet (5). In addition, the tip of the other presser frame (■) is a bag opening (1) K, which will be described later with swinging pieces (up and down) pivoted in two upper and lower stages that can horizontally swing around the vertical axis. The slider (9) of the provided fastener (1) is stretched in two stages, upper and lower, so that it can come into contact with the movable locking arm (to) and the slider (9), and the swinging piece (to) ), 13!il locking arm (to) and a switch (to) that contact-senses swinging due to contact with the slider (9).

(to) is equipped, and if only the upper swinging piece (to) is activated, it is determined that the locking arm (to) has operated without locking the slider (9), and the fastener is re-fastened. The locking arm a8t is actuated to perform the closing operation.

A horizontal axis head is located on the outer side of the lower end of the movable discharge port (5A), and a shutter member (1 (4), (I
OA) in its occluded state at its tip (10a).

(10m) The shutter member (10m) is formed in a concave and convex shape in plan view, and the shutter member (
IOA), (IOA) t” The lowering operation of the movable discharge port (5A) is automatically swung to the open position while the bag opening (1) of the storage bag (3) is opened wide. Thus, the movable discharge port (5A) is configured to be guided to be inserted into the bag (3).

The sensor @ is used to confirm the open position of the bag (3), and this detection operation causes the first lifting operation lever (5a) of the rotating chain (6), which will be described later, to be lowered. It allows rotation.

To explain in detail the automatic bagging mechanism attached to the hopper (8) side, (4) is @1 arm for lifting and lowering the lifting operation lever (5a) with respect to the movable discharge port (5A), and αη is A second arm for opening and closing the opening operation lever (7a) for the shutter +71K,
(to) is a retaining member for contacting and operating the swinging operation member (241) for unlocking the shutter (7) in the open state, which will be described later;
In addition, the slider (9) of the zipper (E) equipped with the opening (fl)K of the storage bag (3) is also used as a companion locking arm that moves in the direction of full closure, and these are configured to rotate. The first rotational movement from the first position to the second position via the chain α causes the first arm (
(g) to lower the elevation control lever (5a) and the locking arm (to) to bring the swinging operating member (2) into contact (in this case, there is no direct action on the locking mechanism).
The opening operation of the opening operation lever (7a) by the second arm αη is performed in the order described, and the second rotational movement from the second position to the third position via the first position causes the second arm (1 ?) Closing operation of the shutter (7) by releasing the lock (by releasing the lock by releasing the locking arm (70) and swinging the locking arm (to) to the swinging operation member (to))
The lifting operation of the lift operation lever (5a) by the arm (G) and the closing operation of the slider (9) by the locking arm (To) are performed in the order described, and so that they are attached to the same chain link. Molded and attached as one piece. The rotary chain α, which is wound and stored in a case (toward) disposed in front of the bag discharge side of the discharge port (5), is arranged under the discharge port (5) of the bag (3) (transfer detecting that the switch is in the first position;
The rotary movement starts automatically, and the movable discharge port (5A) is lowered into the bag opening (ll) and the first shutter (7) is opened (and the limit switch (Sρ) is Based on the detection, the first rotational movement is automatically stopped, and based on the detection of the full detection switch (Sρ) provided in the movable discharge port (5A) K, the second! The shutter (7) is operated to close and is temporarily stopped at this point.

In other words, a limit switch (9) is provided that senses the swinging of the swinging operation member (2) of the locking mechanism for the first shutter (7)K to the unlocking position, and the chain m is When the limit switch (S3) is activated, a timer (not shown) in the control circuit of the entire system is activated, and the system is configured to restart after a certain period of time has elapsed.

When the chain is activated, the movable discharge port (5A) is raised, and when the chain (19) reaches the $1 position, it is temporarily stopped for a certain period of time, and then activated again to perform the zipper closing operation. The limit switch (to) indicates that the slider (9) is closed.
(Thus, the return rotational movement to the first position is automatically started, and the return rotational movement etc. is automatically stopped based on the detection of the limit switch (S4).

As shown in Fig. 1 (thread pitch (L) of the threaded part surface)
In the bag delivery direction, the first half is small and the second half is large, and
The intermediate portions of these darknesses are formed so that the pitch (L) as a whole changes continuously so that the pitch gradually increases. Therefore, while pressing and moving the eyelet (2) of the bag (3) in the standby position by the spring (2), it is relatively easy to engage the threaded portion 0 because the one thread pitch L+ is small. I can do it.

In addition, since the thread pitch (L) of the rear half of the threaded portion is set to be relatively large, the movable discharge port (5A)
A sufficient opening area of the bag (3) can be secured to insert the bag into the bag opening (1). Furthermore, since the pitch fL)K is set to change continuously between the latter half and the first half, the bags (3) can be fed smoothly.

[Another example]

■ As shown in FIG. 5, the threaded portion (211) may be formed over approximately the entire length of the rotating shaft (4), and the pitch ILI may be configured to continuously become Sakhalin in the latter half of the bag delivery direction. In this case, since the thread is engraved over the entire length, it is not necessary to press the eyelet (2) into the thread groove α with a pressing member to engage it, and for that reason, the spring A pressing member such as (2) is not required.Furthermore, since the pitch fL) is small in this part, it can be advantageously stacked with bags (3) and can be used as a standby position.

@ The thread rIIt of the threaded portion 21+ (t4 is the pitch (
The smaller (L) is, the shallower it is, and the larger it is, the deeper it is. Therefore, since the first half of the threaded portion 1211 is shallow, there is little contact resistance between the eyelet (2) and the thread groove α→, making it relatively easy to transfer, and the second half is deep, so the posture regulating force against the eyelet (2) is large. This makes it easy to insert the movable discharge port (ii5A) into the bag opening (1).
