「産業上の利用分野」
本考案は、袋の開口の両端を挟持するチヤツク
を有して、袋詰時には袋を開口し、袋詰完了時に
は口張りをして密閉する形式の自動袋詰機に用い
られる袋口強制口張装置に関するものである。[Detailed description of the invention] "Industrial application field" This invention has a chuck that clamps both ends of the opening of the bag, opens the bag during bagging, and seals it by sealing it when bagging is completed. This invention relates to a bag opening forced opening device used in an automatic bag filling machine of the type.
「従来の技術」

主として用いられるが、空袋にはしばしば底方向
に向いて袋口から皺が生じており、特に薄い袋に
おいては著るしい。``Conventional technology'' When filling empty bags with products in an automatic bagging machine, the empty bag is held under the bagging chute with a chuck, the bag opening is expanded from both sides with a suction cup, etc., and the filling valve is inserted into the empty bag. After filling, the chuck is pulled outward and a so-called opening is performed to make the opening of the bag straight and seal it, and then the bag is transferred to the next sealing process. Generally, soft resin bags such as polyethylene bags or kraft paper bags are mainly used as bags, but empty bags often have wrinkles from the bag opening facing toward the bottom, which is especially noticeable in thin bags.
上述の皺を有する袋に袋詰する場合において、
従来の自動袋詰機にあつては、製品充填後チヤツ
クは口張りのため袋口を外方に引張るが、最初に
チヤツクが空袋挟持した位置(以下「原位置」と

張らない構造になつていた。 When packaging in the wrinkled bags mentioned above,
In a conventional automatic bagging machine, after filling the product, the chuck pulls the bag opening outward to seal the bag, but the chuck first places the empty bag in the position (hereinafter referred to as the "original position" and is represented by P). ), and the bag was not pulled any further.
「考案が解決しようとする問題点」
しかしながら、上記従来の技術では初期の皺は
袋口においては依然としてほぼそのまま残り、こ
れをシール機にかけるシール不良を惹起してい
た。"Problems to be Solved by the Invention" However, in the above-mentioned conventional technology, the initial wrinkles remain almost intact at the bag opening, causing sealing failure when applied to a sealing machine.
さらに皺のない袋でも、製品の充填の結果袋の
銅体部が膨み、その影響を受け袋口も若干伸びた
形状となり、上述の場合同様シール不良の原因と
なつていた。 Furthermore, even in bags without wrinkles, the copper body of the bag swells as a result of filling with product, and the mouth of the bag also becomes slightly elongated, which causes a seal failure as in the case described above.
本考案は、上述の従来の欠点を解消し、充填後

をも目的としている。 The present invention solves the above-mentioned conventional drawbacks and provides a forced bag opening device that can remove the cause of seal failure by pulling and sealing the bag opening to a position where no wrinkles remain after filling. To provide a bag opening forced closing device which eliminates excessive tension by setting the maximum closing distance to the width of the bag, thereby eliminating damage to the bag opening. It is also aimed at

The opening closing mechanism is provided with a closing mechanism that opens the bag during bagging, and a closing mechanism that seals the opening of the bag when bagging is completed. The clamping mechanism is composed of a mechanism that moves the pair of chucks from the original position in a direction toward each other at an equal distance, and then returns them to the original position. The opening distance is made smaller than the closing distance, and the closing distance is adjustable, and the maximum distance is set to the width of the bag. It consists in a bag mouth forced opening device with a wide width.

ルをするものである。"Operation" The bag openings held between the pair of chucks are moved from the original position P toward each other by the action of the bag shrinking mechanism. During this movement, the suction cups on both sides of the bag mouth attract the bag mouth and spread it outward, and the material to be filled is filled into the opened bag mouth. Thereafter, it moves away from the original position P by the action of the closing mechanism. However, if this moving distance is too long, the bag opening will be damaged, so the movement should be within the width of the bag at most. The initial wrinkles at the bag mouth are then removed and the bag becomes completely straight. In this state, the bag is transferred to a sealing machine and sealed completely.

When the bag 1 is supplied, the pair of chucks 2, 2
Pinch both ends of the bag opening. The position of the pair of chucks 2, 2 which are first held is the original position P described above, and in the state where the chucks 2, 2 are located at the original position P, some bags have already wrinkled. (FIG. 5 1) Next, by the action of the mouth tightening mechanism A, the pair of chucks 2, 2 move from the original position P in the direction X1 in which they approach each other (FIG. 5 2). At the same time as the chuck begins to move to X1 , the suction cups S on both sides of the bag mouth suck the bag mouth and expand it outward, and after inserting the opened filling valve into the opened bag mouth, the product is filled. ,
Thereafter, by the action of the closing mechanism B, the pair of chucks 2, 2 are moved in a direction X2 away from each other outward from the original position P. The initial wrinkles at the mouth of the bag are then removed and the bag becomes completely straight (Fig. 5, 3).
If the bag is transferred to a sealing machine in such a state and sealed, a perfect seal can be expected.
以下実施例について詳述する。 Examples will be described in detail below.

いる。 Reference numeral 1 denotes a bag body (empty bag), and a pair of chucks 2, 2 are both constituted by a pair of claws 21, 21, and hold both ends of the bag opening. The chucks 21, 21 are opened and closed by the operation of a cylinder 22. The cylinder 22 is moved along with the chuck 2 in the lateral direction (X 1 ,
It is movable in the X2 direction) and is connected to the links that constitute the mouth closing mechanism A and the mouth closing mechanism B, and to the cylinder 1 for driving the links. The mouth tightening mechanism A has an immovable shaft 31 located between the left and right cylinders 22, 22.
and a rotatable rod 3 at both ends of a link 32 which is fixed to the shaft 31 and rotates together with the shaft 31.
3, 33 are attached, and the other ends of the rods 33, 33 are rotatably connected to the cylinders 22, 22, while another link 34 is attached to the shaft 31.
A cylinder rod 35 serving as a driving source for the mechanism A is rotatably connected to the other end of the link 34, and the other end of the cylinder 35 is supported by a pin 39. Next, the lip closing mechanism B is realized by making the position of a pin 39 that supports the cylinder 35, which is the driving source of the mouth closing mechanism A, movable. In other words, pin 39 has cylinder 4.
1 is connected. In order to adjust the stroke, a stopper 42 is disposed in contact with the pin 39 support portion, and the length of the stopper 42 is variable so that the length of the opening can be adjusted.

すくした。 To explain the operation of the mouth tightening mechanism A and the mouth tightening mechanism B of the above embodiment, when the mouth tightens, when the rod of the cylinder 35 contracts, the link 34 and the ring 35 rotate clockwise around the shaft 31, and the rod tightens. 33, 33 are both pulled inward, and accordingly, the cylinders 22, 22 attached to the tips of the rods 33, 33 are pulled inward,
As a result, the chucks 2, 2 move inward, that is, in the X1 direction. Next, when the mouth is tightened, the odor is released from the cylinder 41 at the same time as the rod of the cylinder 35 is extended.
The rod shrinks. Then, the rods 33, 33 operate in exactly the opposite manner as described above due to the expansion of the cylinder 35, and return to the original position P. However, at the same time, the rod of the cylinder 41 is extended, so the cylinder 35 becomes nearly horizontal, and the link 34 is rotated counterclockwise by that amount, so that the rods 33, 33, that is, the chucks 2, 2 are moved from the original position P. also on the outside
It will be located in the X 2 direction. In addition, in Figure 3,
The rod of the cylinder 41 is shown in a state in which it is in contact with the stopper 42 to make it easier to understand their relationship.

It can also be used as a reminder.

Therefore, no matter what kind of bag or filling conditions are used, the bag opening can be completely sealed without wrinkles after filling, contributing to the improvement of packaging operations. Furthermore, since the opening distance was set to the maximum width of the bag, there was no damage to the bag opening.
