The object to be packaged is introduced into the payout opening 85. Further, a weight detecting means 91 such as a load cell is provided at the rear of the device,
The output from this is fed back to the packaged material supply means 73. With respect to the packed object filling device 77, a vertically movable packaged object supply port 93 provided below the dispensing port 85 of the quantitative weighing device 75, and the packaged object supply port 9

きることになるのである。これは、装置の汎用性と高い
充填速度とを両立する上で重要な技術である。Here, the package supply port 93 is provided separately from the dispensing port 85 of the quantitative measuring device 75,
By setting the area of the lower opening 99 smaller than the area of the upper opening 101, it is possible to apply the packaging bag of various standards from small to large. And, in particular, with respect to the passing amount of the packaged object per unit time at the dispensing port of the quantitative weighing device, depending on the falling speed and the lower opening area when the packaged object freely falls in the cylinder and reaches the lower opening. The feature is that the lower opening area and length of the tubular body are set so that the amount of the packaged object per unit time that can be passed through the determined lower opening is large. That is, in the conventional automatic weighing and packaging apparatus, the object to be packaged is directly filled into the packaging bag 11 through the dispensing port 85, but if the packaging bag of various standards from small size to large size is targeted, the dispensing port 85 is inevitable. Since it is necessary to reduce the diameter, it takes a long time to fill a large packaging bag. However, the above-mentioned packaged material supply port 93
Is used, the object to be packaged is accelerated by gravitational acceleration while the object to be packaged falls freely, and the lower opening 99 is moved to the upper opening 1
The vehicle will pass at a higher speed than when 01 is passed. On the other hand, since the passing amount of the packaged object per unit time is determined by the product of the passing speed and the cross-sectional area, by setting the cross-sectional area of the upper and lower openings and the length of the tubular body to the optimum values, the upper opening 1
Although the cross-sectional area is smaller than 01, it is possible to realize the same amount of passage per unit time in the lower opening 99 as in the upper opening 101. Therefore, it is possible to obtain a high filling speed even for a large packaging bag while targeting a small packaging bag. This is an important technique for achieving both versatility of the device and high filling speed.

を得ることができる。Next, detailed operations of such an automatic weighing and packaging apparatus will be described. First, the shutter 83 of the package supplying means 73 is opened to introduce the package into the quantitative measuring device 75, and the weight is detected by the weight detecting means 91 to reach the preset specified weight at the same time. By closing the shutter 83 of the package supply means 73, the weighing of a fixed weight of the packaged object is completed, and the quantitative weighing device 7 is temporarily operated.
A predetermined amount of items to be packaged is pooled in 5. Next, in the packaging bag supply device 79, the packaging bag clamping means 9, 9 clamps one packaging bag 11, and the opening 105 of the packaging bag 11 forms the packaging bag opening / closing means 95 by the rotational movement of the rotating arms 3, 3. It is transported to the facing position. At this time, as described above, the packaging bag clamping means 9, 9 clamps the optimum position which does not come near or far from the opening, so that various narrowed portions in the packing object filling device 77 can be easily carried out. In addition, it can be securely inserted, and the packaging bag 11 is not picked up by stacking two sheets. Although not shown in the drawing, it is necessary to clamp both sides of the packaging bag 11 in the width direction with respect to the packaging bag opening / closing means 95 by appropriate clamping means. When the packaging bag 11 is sandwiched, the packaging bag opening / closing means 95 adsorbs the packaging bag 11 and opens it, and the opening 105 of the packaging bag 11 opens to a predetermined size. When the packaging bag 11 is opened, the article supply port 93 is lowered and the packaging bag 11 is opened.
The shutter 89 is inserted by the driving means such as the fluid cylinder 87, and the article to be packaged is introduced into the dispensing port 85. At the same time, the items to be packed are introduced into the dispensing port 8
5 is sequentially filled into the packaging bag 11 through the article-to-be-wrapped supply port 93, but since the supply speed to the delivery port 85 is overwhelmingly high, the product is delivered to the article-to-be-packaged supply port 93 while being delivered into the delivery port 85. It will accumulate temporarily. Then, the material is supplied to the object-to-be-packaged supply 93 at a certain discharge speed. Further, as described above, the discharging speed from the packaged material supply port 93 to the packaging bag 11 is the discharge port 85.
Since it is almost the same as the discharge speed from the packaged material supply port 93 to the packaged material supply port 93, it is possible to obtain a high filling speed even with a large packaging bag while setting the cross-sectional area of the lower opening 99 of the packaged material supply port 93 to be small. .

直後から充填終了時の間で適宜設定すればよい。In this way, as the packaging bag 11 is filled with the article to be packaged, the lifting lifter 103 rises to support the weight of the article to be packaged. Then, when a predetermined amount of the object to be packaged is filled, the lift lifter 103 descends to discharge the filled packaging bag. The rising timing of the lifting lifter 103 may be appropriately set between immediately after the start of filling and at the end of filling depending on the size of the packaging bag 11, the content of the packaged object, and the like.
