に構成してある穀物の自動袋詰め装置に関する。[Detailed description of the invention] [Field of industrial application] The invention is mainly used mounted on combine harvesters, harvesters, etc. The storage bag is configured to be forcibly fed progressively in the axial direction at a constant pitch through a threaded portion formed on the rotating shaft, and placed parallel to the lower end of the grain outlet. A swinging opening/closing type shutter member is provided, and this shutter member is moved in conjunction with the downward sliding movement of a movable discharge port that can protrude further downward from the lower end of the grain discharge port, so that its tip portion is fed out and positioned. The present invention relates to an automatic grain bagging device configured to be inserted into an opening of a bag.

〔従来の技術〕[Conventional technology]

（実願昭58−148016号）。 Conventionally, the pair of rocking opening/closing type shutter members are formed so that their tips are in a positional discrepancy when they are in a closed state, and both are operated simultaneously to insert the shutter member into the opening of the bag and to release the shutter member inside the bag. The tip ends of the shutter members were configured to cross each other and be inserted deeply into the bag and further opened (Utility Application No. 148016/1983).

〔考案が解決しようとする問題点〕[Problem that the invention attempts to solve]

前記シヤツター部材が閉塞状態から袋開口作動
をするに、同時に作動するように構成されている

の繰出し方向前後等分にならざるを得なかつた。
しかし乍ら、吐出口の巾方向中央に袋の繰出し停
止位置を設定していても、前記回転軸の回転停止
精度その他によつて、袋は前記停止位置を越えて
停止するものが多いものである。 Since the shutter member is configured to operate simultaneously when the bag is opened from the closed state, as shown in FIG. 1
The allowable amount of the bag delivery stop position due to the gap A with 0a had to be equally divided in the front and back of the delivery direction from the position of the two-dot chain line to the one-dot chain line position.
However, even if the bag dispensing stop position is set at the widthwise center of the discharge port, the bag often stops beyond the stop position due to the rotational stopping accuracy of the rotating shaft and other factors. be.

従つて、袋の前記のような停止特性に対して、
正規の停止位置を越えた際の許容量に不足をきた
すことがあり、袋の開口が旨く行なえないことが
あつた。 Therefore, for the above-mentioned stopping characteristics of the bag,
When the bag exceeds the normal stopping position, the capacity may be insufficient, making it difficult to open the bag properly.

本考案の目的は前記袋の停止特性を考慮して
も、袋の開口作業が円滑に行なえるものを提供す
る点にある。 An object of the present invention is to provide a bag opening operation that can be carried out smoothly even when the stopping characteristics of the bag are considered.

に対して、一定のタイムラグを持つて、前記可動
吐出口に連動して揺動させる機構を設けてある点
にあり、その作用効果は次の通りである。 The characteristic configuration according to the present invention is such that a shutter member located on the lower side in the bag dispensing direction is connected to the movable discharge opening with a certain time lag between the shutter member and the other shutter member. The mechanism is provided with a mechanism for swinging in conjunction with the movement, and its effects are as follows.

〔作用〕[Effect]

つまり、第２図に示すように一方のシヤツター
部材１０Ａを先行作動させることによつて、この
一方のシヤツター部材１０Ａが袋３に挿入される

り、図中２点鎖線の場合）その一方のシヤツター
部材１０Ａが先行して開口することによつて他の
シヤツター部材も追従して開口作動できる。 In other words, by pre-activating one shutter member 10A as shown in FIG. If it is within the width, the tip 1 of the other shutter member 10A
Even if 0a is not located within the opening width (in other words, in the case of the two-dot chain line in the figure), one of the shutter members 10A opens in advance, so that the other shutter members follow and open. Can operate.

従つて、従来のように両シヤツター部材の先端
部が袋の開口幅内に位置しなければならない従来
のものに比べてその停止位置の許容量を大きくで

で、その大きくなつた許容量を袋の基準停止位置
を越えた側へ設定できるので、袋の停止特性に合
致したシヤツタ作動が可能である。 Therefore, the permissible amount of the stop position can be increased compared to the conventional one in which the tip ends of both shutter members must be located within the opening width of the bag, and also Since the shutter member located on the lower side in the feeding direction is configured to operate later than the others, its increased tolerance can be set beyond the bag's standard stopping position, so that the bag stops. It is possible to operate the shutter in accordance with the characteristics.

〔考案の効果〕[Effect of idea]

その結果、袋の繰出停止精度の許容量が大にな
つた分、シヤツター部材での開口作動ミスが抑え
られ、自動袋詰め作業の全体効率を向上させるこ
とができる。 As a result, since the allowable amount of bag delivery stop accuracy is increased, errors in opening operations by the shutter member can be suppressed, and the overall efficiency of automatic bag filling work can be improved.

It is a second arm for opening and closing operations, and 18 is an engaging member for contacting and operating a rocking operation member 24 for unlocking the shutter 7 in the open state, which will be described later, and is installed in the opening 1 of the storage bag 3. These locking arms serve as locking arms for moving the slider 9 of the fastener 20 in the closing direction. 1
Due to the rotational movement, the first arm 16 lowers the lift operation lever 5a, the locking arm 18 brings the swing operation member 24 into contact (in this case, there is no direct action on the lock mechanism), and the second arm The opening operation of the opening operation lever 7a by the second arm 17 is performed in the order of description, and the second rotational movement from the second position to the third position via the first position causes the second arm 17 to open the opening operation lever 7a. Closing operation of the shutter 7 due to release of contact and release of the lock by contacting and swinging of the locking arm 18 against the swinging operation member 24, operation of raising the elevator operating lever 5a by the first arm 16, and slider 9 by the locking arm 18. so that the closing movement operations are performed in the order listed.
Moreover, they are integrally molded and attached so that they can be attached to the same chain link. A case 3 disposed in front of the bag outlet side of the discharge port 5
When the switch 34 detects that the rotary chain 19, which is wound and housed in the bag 3, is transferred to a position below the discharge port 5 of the bag 3, the first rotary movement is automatically started, and the movable discharge port 5A into the bag opening 1 and the opening operation of the first shutter 7.
The rotational movement is automatically stopped, and the movable discharge port 5A
The second rotational movement is started based on the detection by the fullness detection switch S2 provided at , the first shutter 7 is operated to close, and at this point it is temporarily stopped.
That is, a limit switch S3 is provided which senses the swinging of the swinging operation member 24 of the locking mechanism relative to the first shutter 7 to the unlocked position, and the operation of the limit switch S3 causes the chain 19 to
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 restarted after a certain period of time has elapsed. By starting the chain, the movable discharge port 5A rises,
When the chain 19 reaches the first position, it is temporarily stopped for a certain period of time, and then restarted to perform the fastener closing operation. By sensing through the limit switch 36 that the slider 9 has been closed during this fastener closing operation, the first
The return rotational movement to the position is automatically started, and the return rotational movement, etc. is automatically stopped based on the detection of the limit switch S4.

ように構成してある。 As shown in FIGS. 1 and 2, between the movable outlet 5A and the shutter member 10A located on the lower side in the bag delivery direction, there is a notch 5a at the lower end of the outlet 5A and a cutout 5a at the upper surface of the shutter member 10A. A mechanism 54 consisting of an arm 10b that can be fitted and engaged with the protruding notch 5b is provided, and the shutter member 10A located on the downstream side in the bag dispensing direction is moved in conjunction with the downward movement of the movable discharge port 5A. It is configured to swing downward with a delay of a time lag corresponding to the height of the notch 5b compared to the other shutter member 10A.

せた構成をとることができる。 Therefore, about 2 of the bag opening width in the bag feeding direction centering on the tip 10a of the other shutter member 10A.
The area L corresponding to twice the size can be set as the allowable amount of the bag stopping position, and the configuration can be adapted to the stopping characteristics of the bag, which often deviates to the downstream side in the feeding direction from the reference position. .
