It provides a factor that can be increased.

In general, the straw is a convenient way to drink a variety of drinks, such as juice and milk as already known, these are sold in the above-mentioned various beverages, retail stores are purchased at the appropriate number of drinks when purchasing Will be supplied.

Since the straw is used as the mouth of the human body, the outer surface is packaged to prevent contamination by external dust, etc., and their packaging work is to pack a large amount of straw, so the packaging work by hand is productive. This extremely low relationship requires the emergence of more automated packaging machines.

Conventional packaging device appeared in response to the above requirements, to put a plurality of straw in the already completed packaging bag, to seal the inlet into which the straw is added to complete the straw package, wherein the 'already completed packaging bag' Means the plastic bag which is manufactured by another working device and opened only on the upper side to which the straw is to be fed. The packaging bags are continuously connected so that the straw is put into the open part in the intermittent conveying state to transfer and stop the bags. do.

The conventional straw supply unit has a hopper loaded with a large amount of straw, intermittent driving means for intermittently transporting the packaging bag to the lower side of the hopper, and a straw bag is transported by the driving of the intermittent driving means. It has a basic configuration consisting of an intermittent means to open and close the drop inlet of the hopper by detecting the time or the amount of falling to be introduced into the number.

In addition, the intermittent means has an operating relationship between the intermittent driving means and the intermittent means, that is, when the packaging bags are transported and stopped by driving the intermittent driving means, the number of the intermittent driving means is interrupted and the straw falls. It is equipped with a control means of several electronic, electrical components to control the.

In order to operate the packaging bag intermittently, the straw supply unit employs a motor used as a power generating means as an expensive stepping motor, and a control unit for controlling the operation relationship between the control unit and the intermittent driving unit includes various expensive electronics. This also adds to the economic burden on the user.

In addition, the operation of the intermittent drive as described above delays the working time, and when the straw is put into the packing bag, it is mainly put up and drop-in, and this working state is unevenly inputted with the number of straws formed long up and down. In many cases, the stray that has been severely dropped is caught by the bag's inlet, thereby causing a problem in the packaging.

The present invention was devised to solve the above problems, and the object of the present invention is to ensure that the straw is supplied by continuous driving instead of intermittent driving, and that the straw is supplied in a stable and uniform number. .
