着装置に移されるという問題がある。(Prior Art) A suction belt type bag opening device that opens the bag opening to the maximum extent on the exit side while transporting the bag using a pair of linear endless suction belts is disclosed in JP-A-53-74989. ing. This suction belt-type bag opening device opens the bag mouth while transporting the bag, and the closing of the bag mouth to insert items into the bag is now done at a separate location outside the bag opening device. ing. Therefore, an extra punch is required to maintain the shape of the opened bag opening, which not only complicates the structure, but also because there is nothing to actively maintain the shape of the bag opening when inserting items into the bag. Input of goods becomes uncertain, and
There is a problem in that after the articles are loaded, the bag opening piece is displaced and transferred to the welding device in the subsequent process.

期機構７が設けられている。 Reference numerals 1 and 1' designate endless transfer belts that absorb and transfer the bags 13, and as shown in FIG.
It is provided symmetrically in a plane with respect to the line of travel of the The transfer belts 1, 1' are guided in an annular manner by a guide wheel 2 on the inlet side, a guide wheel 3 in the middle, a drive wheel 4 and an air box 5 on the outlet side, and after first moving in parallel, they move below the chute inlet 8. The bag mouth opens at the point where it hits,
It is arranged so that powder and granular material can be introduced. The pair of transfer belts 1, 1' are connected via the drive wheel 4,
A synchronization mechanism 7 is provided for driving the drive device 6 in the direction of the arrow shown in FIG. 2 and synchronizing the speed and phase of both.
一方、移送ベルト１，１′には複数個の空気孔

うになつている。 On the other hand, the transfer belts 1 and 1' have a plurality of air holes 9, and the air box 5 has a plurality of air holes 10 (FIGS. 4 and 5) on the surface that contacts the transfer belt. Furthermore, the air in the air box 5 is sucked in by an air suction pump 12 via a piping part 11. A total of four air boxes 5 are installed, and each air box is provided with an inclined wall 5a in the center to form a bagging section. By symmetrically opposing the inclined walls 5a in a plan view, a substantially rhombus-shaped space is formed.
従つて移送ベルト１，１′の空気孔９と空気箱
５の空気孔１０とが一致する様にしておけば空気
吸引ポンプ１２を運転することにより、移送ベル

る。 Therefore, by aligning the air holes 9 of the transfer belts 1, 1' with the air holes 10 of the air box 5, the air suction pump 12 can be operated to contact the transfer belts 1, 1'. The bag 13 is attracted to the transfer belts 1, 1' and is transferred together with the transfer belt.
（作用）
この発明の袋口開閉装置は以上のような構成で
あつて、人力あるいは別に設けた自動給袋機によ
り袋１３が本装置に供給される。以下第６図を参
照して本装置の作動について説明する。(Function) The bag opening/closing device of the present invention has the above-described configuration, and the bags 13 are fed to the device manually or by a separately provided automatic bag feeding machine. The operation of this device will be explained below with reference to FIG.
供給された袋１３は移送ベルト１，１′の間
に挟着かつ吸着されながら移送ベルトの回転に
より連続的に図の右方（矢印）へ移送される
（第６図−イ）。 The supplied bag 13 is continuously transferred to the right (arrow) in the figure by the rotation of the transfer belt while being sandwiched and attracted between the transfer belts 1 and 1' (FIG. 6-a).
袋１３が移送ベルト１と１′の間隔が拡がる
部分に達すると袋１３は移送ベルト１，１′に
吸着されているため、袋口片は移送しつつ離間
され、次第に袋の口部を開いていく（第６図−
ロ）。 When the bag 13 reaches the part where the gap between the transfer belts 1 and 1' widens, since the bag 13 is attracted to the transfer belts 1 and 1', the bag opening pieces are separated while being transferred, and the bag opening is gradually opened. (Figure 6-
B).
袋の口部が完全に開いた状態（第６図−ハ）
でシユート投入口８により粉粒体を袋１３に投
入する。 When the mouth of the bag is completely open (Fig. 6-C)
Then, the powder and granular material is charged into the bag 13 through the chute input port 8.
粉粒体の投入完了後、移送ベルト１，１′の
間隔が挟まり始め、袋１３は移送ベルトに吸着
されているため、移送ベルトと共に次第に袋口
部を閉じ始める（第６図−ニ）。 After the loading of the powder and granules is completed, the gap between the transfer belts 1 and 1' begins to narrow, and since the bag 13 is attracted to the transfer belt, the bag opening gradually begins to close together with the transfer belt (FIG. 6-D).
再び移送ベルト１，１′は接触しかつ平行と
なり（第６図−ホ）、袋口部は移送ベルト１，
１′の間に挟まれ完全に閉鎖される。 The transfer belts 1, 1' are again in contact and parallel (Fig. 6-E), and the bag opening is connected to the transfer belts 1, 1'.
1' and is completely closed.
以上の一連の工程が完了したならば、袋１３は
次工程の封口装置へ渡される。 When the above series of steps are completed, the bag 13 is transferred to a sealing device for the next step.
尚、粉粒体投入後の袋及び粉粒体の重量は袋の
