DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vertical bag-making bag filling and packaging method according to an embodiment of the present invention will be described with reference to FIGS. In the method of the present invention, as shown in FIG. 1, a continuous wrapping film F is hung on a former 1 and bent in a tubular shape so as to wrap a product dropping / filling tube 2 and a film edge f is paired with a pair of vertical sealing heaters 5.
Vertically seal the product by dropping it as a packaging cylinder H below the product drop-filling cylinder 2, and drop-fill the packaged object W into the packaging cylinder H through the product drop-filling cylinder 2. The horizontal seal / cut is performed by a pair of heaters 3 and 3 for horizontal seal / cutting cutters that perform box motion. The pair of horizontal seal / cutting heaters 3 and 3 are supported by a pair of heater blocks 8 and 8 which are separated from each other by an air cylinder 6 and a link mechanism 7 which is operated symmetrically, and further, a pair of heater blocks 8 are provided. , 8 are connected to a winding belt 17a of a winding device 17 driven by a servo motor 16 (not shown) by a coupling tool 18 and supported by a lift table 9 which is moved up and down by the reciprocating movement of the winding belt 17a. There is. The pair of horizontal seal / cutting heaters 3 and 3 are closed at the raised position, lowered as they are, opened at the lowered position and then raised. The pair of shutters 4 and 4 includes an air cylinder 10 and a link mechanism 11 that is operated bilaterally.
It is designed to be separated by and. The pair of flat film pinching means 12, 12 provided on the upper surfaces of the pair of horizontal sealing / cutting heaters 3, 3 are attached to the upper surface of the heater and project several millimeters from the heater surface. When the upper side of the horizontal sealing portion of the packaging cylinder H is closed integrally with the closing operation of the heaters 3 and 3, the flat sealing is performed prior to the horizontal sealing, and after the compression, the spring 13 contracts and is opposed to the upper surface of the heater. It can be slid.
The pair of flat film pinching means 12, 12 have a role of preventing wrinkles from being generated at the lateral sealing portion and a role of separating the packaging film F from the upper surface of the heater, but they may be omitted.

In the method of the present invention, as shown in FIGS. 1 and 2, the object W to be packaged is a sphere such as a deodorant ball, a candy ball, or an elastic plastic ball. Is slightly larger than the diameter of the sphere W, and the sphere W is supplied from a part feeder (not shown) through the chute 20 so as to be superposed in a line in the product dropping and filling cylinder 2. Then, the space between the pair of shutters 4 and 4 is narrowed so that the packaging cylinder H has a required flatness just below the product drop filling cylinder 2 to prevent the sphere W from being fed out from the lower end of the product drop filling cylinder 2. In this state, the pair of heaters 3 and 3 for horizontal seal / cutting cutters are closed immediately below the pair of shutters 4 and 4 to horizontally seal the packaging cylinder H and cut between the seals. Next, after opening the pair of shutters 4 and 4, the pair of horizontal seal / cutting heaters 3 and 3 are lowered to pull down the packaging cylinder H, so that the sphere W in the packaging cylinder H is equivalent to one bag. When the shutters 4 and 4 are passed by the number, the operation of narrowing the interval between the pair of shutters 4 and 4 is performed. Subsequently, the heaters 3 and 3 with cutters for horizontal sealing / cutting are slightly lowered to pull the packaging cylinder H to separate the sphere W immediately below the shutters 4, 4 from the sphere W stopped by the shutters 4, 4. . Next, the pair of horizontal seal / cutting cutter heaters 3,
After opening 3 to separate the package and return to the ascending position, the pair of lateral seal
The sealing / cutting operation of the heaters 3 and 3 with a cutter for cutting is performed. The above operation process is one packaging cycle.

The mutual relationship between the opening / closing operation of the pair of shutters 4 and 4 and the box motion of the heaters 3 and 3 with cutters for horizontal sealing / cutting is performed by the following aging operation. When the elevator 9 supporting the heaters 3 and 3 for cutters for horizontal sealing / cutting stops ascending, the projection 21 attached to the elevator 9 is fixed to an appropriate fixing member so that the height can be adjusted freely. When the first proximity sensor 14 outputs the detection signal, the air cylinder 6 operates to close the heaters 3 and 3, and the air cylinder 9 operates to operate the pair of shutters 4. 4 is opened, and when the heaters 3 are closed, the servo motor 16 is activated to start lowering the elevator 9, and the fourth sphere W is slightly lowered from the shutter 4. At this time, the protrusion 21 projecting from the lift 9 is attached to the second proximity sensor 15
Is detected, the air cylinder 10 is reversely actuated based on the detection signal of the proximity sensor 15 to close the pair of shutters 4 and 4, and when the elevator base 9 continues to descend to the lower limit position, the protrusion is generated. 21 is detected by the third proximity sensor 19, the servo motor 16 stops driving based on the detection signal of the proximity sensor 19, the air cylinder 6 operates, the heaters 3 are opened, and then the servo motor 16
Is driven in a recoil manner, and the heaters 3 are raised and returned.

In FIG. 2 (a), a pair of shutters 4 and 4 provided immediately below the product dropping and filling cylinder 2 includes a packaging cylinder H.
In order to flatten the packaging cylinder H with a space between them, the spacing is narrowed to the radial distance of the sphere W to prevent the sphere W from being fed out from the lower end of the product dropping and filling cylinder 2, and also to form a pair of horizontal seals. It is in a state where the heaters 3 and 3 with cutters for cutting are closed to perform horizontal sealing and cutting. The horizontal double-row seal of the packaging cylinder H by the horizontal seal / cutting heaters 3 is composed of a top horizontal seal on the upper side of the bag below the heater and a bottom horizontal seal of the next bag on the upper side of the heater. is there.
The pair of shutters 4 and 4 have horizontally rotatable rollers 4a and 4a, each of which has a diameter slightly smaller than the diameter of the spherical body W, so as to face each other horizontally and in parallel.
a and 4a are used to flatten the packaging cylinder H to a desired level to prevent the spherical body W from being fed out from the lower end of the product drop filling cylinder 2.

FIG. 2B shows the next step of FIG. 2A, in which the pair of shutters 4 and 4 are opened and the spheres which are prevented from falling by the shutters are a pair of film flats. It is in a state of falling by gravity onto the pinching means 12, 12. Therefore, the sphere W is clogged at the bottom of the bag and the packaging becomes tight. The film flattening and pressing means 12 and 12 also serve to prevent the packaging film from being pressed against the upper surfaces of the heaters 3 and 3 with cutters for lateral sealing and cutting under the weight of the sphere W to melt and break. By laminating a material having low heat conductivity on the upper surface of the heater, it is possible to prevent the packaging film from being melted and broken by the heat of the heaters 3 and 3 with cutters for lateral sealing / cutting. It is not necessary to receive sphere W at.

FIG. 2 (c) shows the next step of FIG. 2 (b), in which a pair of horizontal seal / cutting heaters 3 and 3 for cutters are packaged with the pair of shutters 4 and 4 opened. Tube H
Is in a state of being horizontally sealed, and is lowered to pull the packaging cylinder H downward. Therefore, as the packaging cylinder H is pulled downward, the spherical body W also descends and passes through the shutter 4. A film transfer means (not shown) is provided on the side surface of the product dropping / filling cylinder 2, and the pair of horizontal seal / cutting heaters 3, 3 pulls down the packaging cylinder H in synchronism with the film. The intermittent transfer is preferable because the force of pulling the packaging cylinder H of the horizontal seal / cut heaters 3, 3 downward is reduced.

FIG. 2D shows the next step of FIG. 2C, in which the fourth sphere W is passed through and the fifth sphere W is passed through from the pair of shutters 4 and 4. To prevent the horizontal seals even after the pair of shutters 4 and 4 are closed.
This is a state in which the heaters 3 and 3 with cutters for cutting are successively lowered by a required dimension and the packaging cylinder H is pulled downward. As a result, the fourth sphere W that has passed between the shutters 4 and 4 and the sphere W stopped by the shutters 4 and 4 are separated from each other by a required distance, and this space between spheres is set as the next horizontal seal / cut position. It has become. In this case, the closing timing of the pair of shutters 4 and 4 is set to the second proximity sensor 1 as described above.
It is based on the detection signal of 5. As described above, when the packaging cylinder H is sandwiched by the heaters 3 and 3 and pulled downward, sliding friction occurs between the packaging body H and the spherical body W blocked by the shutters 4 and 4. In this case, if the shutters 4 and 4 are provided with the freely rotatable horizontal rollers 4a and 4a as described above, there is an advantage that the sliding friction can be suppressed to be small.

FIG. 2 (e) shows the next step of FIG. 2 (d), in which the heaters 3 and 3 with cutters for horizontal sealing / cutting are opened and the sphere W is packaged in four rows. As the product S falls by gravity, the film flat clamping means 12, 12 are simultaneously opened, and the four spheres W below the shutters 4, 4 are packaged by a certain dimension up to the bottom of the bag which is laterally sealed at the bottom. The state which descended in H is shown. At this time, the distance between the uppermost sphere W in the fourth sphere W and the shutters 4 and 4 is further increased, and in this state, the pair of horizontal seal / cutting heaters 3 and 3 with cutters are arranged. When the heater is closed at the position shown in FIG. 2 (a), the heater is at a level capable of horizontally sealing the upper side of the uppermost sphere of the fourth sphere. This is to make the packaging tight.

FIG. 2 (f) shows the next step of FIG. 2 (e), in which the heaters 3 and 3 with cutters for horizontal sealing / cutting are shown.
Is in an open state and raised. As shown in FIG. 2A, which shows the next step, when the package is closed toward the packaging cylinder H, one packaging cycle is completed.
