るものであった。In the weighing and packaging apparatus as described above, it is easy to replace the packaging material and set the positioning,
It is used when the weight setting of the weighing package covers multiple types of weight. However, such a weighing and packaging apparatus has to perform the steps of opening the packaging bag, filling the packaging bag with the contents, and sealing the packaging bag at the same position in sequence, respectively. Since the above process cannot be operated independently, the processing capacity was extremely low. As described above, there is a drawback in that the processing capacity is low in spite of the convenience of being able to handle a plurality of types of set weights.

望まれている。In many cases, the packaging material for filling is provided with a color or a design that represents the image of the content, and in many cases, the content and the packaging bag are integrally formed into a product. In addition, the customer side only needs to purchase the required amount in the required amount, and selects the product that matches the quality of the product and the image of the packaging bag. It is in the form. Therefore, there is a demand for the development of a weighing and packaging apparatus that can handle a plurality of types of packaging materials and set weights in a small amount and has a large filling and packaging processing capacity.

As described above, the representative of the weighing and packaging apparatus disclosed in Japanese Patent No. 1001 is easy to replace the packaging material,
Although the weighing and packaging settings can accommodate a plurality of set weights, it is difficult to reduce the weighing and packaging processing time for each weight, and the number of devices is increasing in order to cover the processing capacity. Not only is it possible to set various weights in order to meet the needs of consumers, but it is also a great challenge to increase the processing capacity per weighing and packaging device in order to reduce capital investment and increase the processing capacity.

低下は全体の処理速度の低下につながっていた。By the way, an air cylinder driven by air has been frequently used as a drive device in the packaging machine for the purpose of increasing the speed. However, the above-mentioned rotating cylinder driven by the air cylinder is used. Since the linear motion of the air-cylinder is converted into the rotary motion of the rotary arm, the high speed cannot be demanded. The decrease in the operation speed in this main part has led to the decrease in the overall processing speed.

に充填作業が開始できるようになった。First, in the present invention, since the opening transfer means is provided between the transfer means and the metering and filling means, the opening transfer means transfers the packaging bag having the upper part opened to the packaging seal means. Became possible. So this is
Since an open packaging bag is supplied to the packaging seal means,
Immediately after being supplied, the contents can be supplied (dropped) from the measuring and filling means to the packaging bag. With respect to this point, in the prior art, even if the packaging bag was supplied under the filling means, the filling means had to wait for the opening of the packaging bag by another opening means before performing the filling.
That is, other functions are stopped to open the packaging bag. In the present invention, since the packaging bag is opened by the opening transfer means and is transferred to the packaging seal means provided below the weighing and filling means, when the packaging bag can be transferred to the packaging seal means, the packaging bag is opened. The time has been reduced and the filling work can be started immediately.

タイムが無くなった。Further, since the transfer means, the opening transfer means and the packaging seal means are configured separately from each other, the transfer means immediately after the transfer of the packaging bag from the transfer means to the opening transfer means. It is possible to receive the supply of the packaging bag from the packaging bag supply means, and the opening transfer means is provided in the packaging sheet.
After transferring the packaging bag to the packaging means, the opening transporting means can immediately receive the next packaging bag from the transporting means and open the upper side of the packaging bag to prepare for filling the next contents. That is,
The contents are filled in the packaging bag which has been transferred to the packaging seal means by the opening transfer means, and while the opening portion of the packaging bag is being sealed, the next packaging bag is transferred to the opening. Since it is possible to complete the operations of the transfer means and the opening transfer means for filling, one packaging bag and the next packaging bag can be filled immediately after the sealing is completed, and the packaging sheet can be filled.
With the sealing means, only the continuous operation of filling and sealing can be repeated. According to the present invention, when one packaging bag is filled and sealed as in the conventional case, the packaging bag feeding device goes to newly take the next packaging bag, the reciprocating operation time therefor and the opening of the packaging bag. Lost time, such as waiting for time and filling, has disappeared.

る。Next, the packaging bag supplying means, the transporting means, the opening transporting means and the packaging seal means are arranged so that the packaging bag supplied in a hanging state from the packaging bag supplying means can be linearly transported. Therefore, the packaging bag can be transferred linearly between the transfer means and the packaging seal means. That is, by arranging the sandwiching portions for sandwiching the packaging bag provided in each means on a straight line, the packaging bag does not move up and down between the position where the packaging bag is first sandwiched by the transfer means and the packaging seal means. Finally, it can be delivered up to the packaging seal means. From this, there is no displacement of the tip position of the packaging bag due to delivery, and it is very easy to set the packaging bag on the packaging seal means. The term "on a straight line" as used herein refers to, for example, a linear movement of the packaging bag in the width direction.

を避けることができる。By the way, a plurality of sandwiching portions of the packaging bag are provided on the circumference, and various means are arranged on the circumference of the sandwiching portions so as to perform the filling and packaging while rotating and moving.
It is a tally type weighing and packaging device. In this rotary-type weighing and packaging device, a large number of sandwiching portions of the packaging bag are arranged on the circumference, and the weighing and packaging processing capacity is greatly improved. However, since many sandwiching portions are arranged on the circumference, the device is large. It was. From the above, in the present invention, by arranging the respective means so that the packaging bag moves on a straight line, it is sufficient that the sandwiching portion has a number enough to connect the respective means, and the transfer means and the opening. Since the transfer means and the packaging seal means are provided side by side and a large amount is not required, it is possible to avoid an increase in the size of the entire apparatus.

This not only leads to gripping mistakes in the packaging bag, but also the loading port of the contents does not enter the opening of the packaging bag when filling the contents, or the seal at the opening after filling is complete. In some cases, packaging failure occurred.

包装袋の開口部先端位置は常に一定となる。The packaging bag supply means of the present invention comprises a roll-shaped packaging material holding portion for rotatably holding a hollow long roll-shaped packaging material and the roll-shaped packaging material in a suspended state. And a packaging bag forming unit for cutting the long roll-shaped packaging material supplied from the packaging material supply unit to an arbitrary length and bottom-sealing to form a packaging bag. As a result, it is very easy to set the tip of the packaging bag, which is originally difficult. That is, the packaging bag supplied in the hanging state by the packaging bag supply means,
After being sandwiched by the sandwiching portion of the transfer means, the packaging bag forming portion cuts off the roll-shaped packaging material, and the cut-off position becomes the tip of the packaging bag opening, and the packaging bag to be supplied to the transportation means. The position of the tip of the opening is always constant.

Has the opening of the packaging bag and the bottom of the sealed packaging bag at the top, and if the cutting and sealing are performed once before the operation, the bottom of the packaging bag is completed and the rest is rolled. The tip position of the opening does not change even if the feed amount of the wrapping material changes a little, and as long as the change in the feed amount does not significantly change the inner volume of the packaging bag, the packaging bag and its opening tip position are always stable. Is secured.

It suffices to hold the transfer device at that position and transfer it. Since the positional relationship between the holding device and the package forming part of the transfer device is constant, there is no need to pay attention to positioning the packaging bag or aligning the tips. It was In addition to the roll-shaped packaging material, there is also a conventional example in which a single-bag packaging bag is used. In this case, however, it is necessary to align the ends of the single-package bags that have been stacked and take other measures to prevent double packaging. I had to take it.

ら、高速化に伴う弊害は発生しない。Further, in the present invention, the linear transfer mechanism of the packaging bag in the transfer means and the opening transfer means is a rodless cylinder. Speeding up the transfer and supply of packaging bags is a necessary condition for speeding up of weighing and packaging equipment.
However, the conventional feeding and transferring of packaging materials and packaging bags are often carried out by a rotating arm having a holding means or a carrying belt. Most of this rotating arm is driven by an air cylinder, but since the linear movement of the air cylinder is converted into the rotating movement of the rotating arm, high speed is not required, let alone belt driving. I can't expect any more. In view of this, in the present invention, a rodless cylinder capable of high-speed linear movement between the transfer means and the opening transfer means and between the opening transfer means and the packaging seal means is used as a transfer means, and a rodless cylinder- Since the packaging bag is directly transferred at the moving speed of, the packaging bag can be transferred faster than ever before. Further, since the rodless cylinder is air-driven, shock-absorbing means at the time of stoppage due to speeding up of transfer can be easily realized by providing a shock absorber, so that a harmful effect due to speeding up occurs. do not do.

Can be supplied to the means 5. Similarly, the transfer means 3 can prepare the next packaging bag 8 until the process of the opening transfer means 4 is completed, so that a wasteful time such as waiting for opening the packaging bag is significantly increased. Can be reduced.

になった。According to the present invention, the packaging sheet provided below the measuring and filling means with the packaging bag opened by the opening transfer means.
Since it is transferred to the packaging means, if the packaging bag can be transported to the packaging seal means, the packaging seal means can reduce the time for opening the packaging bag and shorten the time to start the filling operation immediately. It was

が無くなった。Further, this means that while the packaging bag transferred to the packaging seal means by the opening transfer means is filled with the contents and the opening portion of the packaging bag is sealed, Since it is possible to complete the operation of the transfer means for transferring the next packaging bag and the opening transfer means, as soon as the filling and the sealing of one packaging bag are completed, the packaging bag of the next packaging bag is completed. Then, the packing seal means can repeat only the continuous operation of filling and sealing. According to the present invention, when one packaging bag is filled and sealed as in the conventional case, the packaging bag feeding device goes to newly take the next packaging bag, the reciprocating operation time therefor and the opening of the packaging bag. Lost time, such as waiting for time and filling, has disappeared.

装置全体としても大型化を避けることができる。Further, in the conventional rotary-type weighing and packaging apparatus, a large number of sandwiching portions of the packaging bag are arranged on the circumference, and the weighing and packaging processing capacity is greatly improved. However, many sandwiching portions are arranged on the circumference. In order to do so, the device was large, but in the present invention, by arranging the respective means so that the packaging bag moves on a straight line, the sandwiching part may have a number sufficient to connect the respective means, Further, since the transfer means, the opening transfer means, and the packaging seal means are provided side by side and a large amount is not required, it is possible to avoid an increase in the size of the entire apparatus.

ろえへの注意が全く必要なくなった。Further, a packaging bag formed by cutting the bottom portion sealed by the packaging material downward and supplying it to the transfer means in a suspended state, cut by the packaging bag forming section while being sandwiched by the transfer means is formed. Since the cut position is the tip portion of the packaging bag, it can be sandwiched by the transport means and transported. In other words, since the positional relationship between the sandwiching section of the transfer means and the package forming section is constant, it is not necessary to pay attention to positioning or aligning the ends of the packaging bag, which has been conventionally required and difficult.
