Abstract

PURPOSE:To cause a packing bag to have a cylindrical form for preventing partial drying, by compressing the bag by vibration and by pulling the bag at the near-by top to shape the bag, and binding a seal part bundled like a bar. CONSTITUTION:Specified culture earth for mushroom is charged in a packing bag 22 binded at the bottom by a screw conveyor 17 and compressed by a vibrator 25 to force the package bag 22 to be cylindrical. Next, the packing bag 22 is stretched by lateral pushing with a bag press 30 to form a straight line at the top of the bag, being held at the top of the charged bag and at the same time the packing bag 22 is further compacted to form a flat face and bound at two points by a binding sealer. After an intermediate point between the two bound points is cut off by a cutter 51, holding members 34, 35 of a squeezer 29 is moved back and the packing bag is dismounted from the bottom plate 27 by a discharger 55 to be taken out by a conveyor or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a packaging device for filling and packaging powdery mushroom culture medium made of sawdust, nutrients for mushroom fungi, and the like.

(2) Prior Art The apparatus shown in FIG. 1 is conventionally known as a filling and packaging apparatus for powdery substances, which is the object of the present invention.

To explain the filling and packaging apparatus, a sheet-like packaging material 2 wound around a roller 1 is moved through tension pulleys 3 to 6.
The cylindrical material engages with the collar-shaped sailor 8 of a garment that is provided around the cylindrical filling injection tube 7 through the cylindrical material, passes between the filling injection tube 7 and the sailor 8, and wraps around the core part 7. formed into a shape. Then, the combination 9 is made with a heat sealer 10.
Further, the packaging bag 12 is sealed in the upper and lower directions by horizontal seal heaters 11, respectively.

On the other hand, in the filling cylinder 7 , a packaging material pull-out device 15 consisting of a pair of p-rollers 13 and a belt 14 is installed below the sailor 8 and is pressed against the filling cylinder 7 through the packaging material 2 . Then, the packaging material 2 is intermittently drawn out by the drawing device 15.

In the conventional device configured as described above, the filling stored in the hopper 16 is weighed by a screw conveyor (not shown) inserted through the filling cylinder 7, and transferred into a cylinder. The lower part of the bag is placed in a packaging bag 12 which is sealed by a horizontal sealing device 11. Next, a specified amount of the packaging bag 12 is removed from the drawer device 1.
5, the upper part is sealed at two places by a horizontal sealing device 11 as shown in the figure, and a cutter (
(not shown) to complete the filling and packaging process.

On the other hand, the remaining seal portion will form the bottom of the packaging bag in the next step.

(3) Problems to be Solved by the Present Invention In the case of products packaged using the conventional apparatus as described above, the sealing surface of the packaging bag 12 is flat as shown in the figure, so that the sealing portion of the packaging bag 12 becomes a thin plate. Therefore, when the mushroom culture medium is filled with this device, the mushroom culture medium located near the seal part tends to partially dry out, and as a result, the mushroom bacteria contained in the culture medium often die, leaving room for improvement. was.

In particular, when filling with a mushroom culture medium, it is necessary to provide small holes in the packaging material, such as polyethylene, in order to maintain the activity of the mushroom bacteria, so this drying tendency is even more pronounced.

Under these circumstances, as a result of intensive research to form the packaging bag into a cylindrical shape that is difficult to dry, the packaging bag is vibrated to compress the filling, and the packaging bag is pulled while pulling the packaging bag near the top of the filling. The present invention was completed based on the finding that a packaging bag can be formed into a cylindrical shape that is difficult to dry even partially by molding the bag and binding and sealing the sealed portion into a rod shape.

That is, the present application provides a filling device configured to form a sheet-like packaging material into a cylindrical shape and fill the inside with a powdery granular material, which is formed from the sheet-like packaging material and filled with a powdery mushroom culture medium. A vibrating device for placing a packaging bag and vibrating it; a device for squeezing the area just above the filled part of the packaging bag; and a binding device for tying the packaging bag in the squeezed area into a rod shape and sealing it in at least two places at the rod-shaped portion. This is a mushroom culture medium filling and packaging device comprising a sealing device and a cutting device for cutting the middle packaging bag at each sealing location.
