Note that the above heat sealing device is equipped with a first heat sealing device 80 and a second heat sealing device 81, and also has a cooling device having a cooling element such as a water cooling pipe instead of a heating element from the above-mentioned -1-sealing device. 82 DJs are set up. Further, 83 is a thermocouple.

Now, take out the empty bags 1 one by one using the vacuum suction cup 9, and
The bag 1 is fed to the feed roller 10 as shown by the two-dot chain line in the figure, and the bag 1 is fed to a predetermined position between the movable claw 11a and the fixed claw 11b of the bag gripping claw 11 by the roller.

The chain converter 12 is then moved by two dimensions and, after stopping, the bag is opened by means of the suction M20.

The rear load 1 remains open due to the rigidity of the bag +A'ft, is transferred to the nostle 34 of the filling device 33, stops there, and is filled with the contents. The breech-pack 1 is hermetically sealed by the sealing bars 35a and 35b of the first and second heat sealing devices 80, 81, and is cooled by the cooling device 82.

Here, the sealing procedure will be explained in detail.

When the presser +A69 descends from the position indicated by the two-dot chain line by a link mechanism (not shown) while pushing down the roller 59.60 against the tension spring 66.67, the clamp 44.53
rotates around the shaft 47 to the position shown by the solid line in FIG. 6, grips the opening of the bag 1 with the sealing squares 35a and 35b, and heat-seals and cools the bag.

Next, the presser member 69 is raised to release the bag 1 and p =
When the bag is conveyed using the J method and the above steps are repeated to complete the first heat roll, second heat seal and cooling steps, the bag 1
is dropped onto the discharge heald 32 and discharged outside the machine in the form of bag products 1a.

The above explanation describes the case where bags 1 are filled and sealed while being transported in a single row. However, when changing to a multi-row transport method with two or more rows, the above-mentioned sealing device and cooling device are added to increase the number of rows. In addition to adding more water to the river, the disadvantage was that the entire device not only became larger, but also had a more complicated structure and increased cost.

Further, a Teflon sheet 73 is wrapped around the sealing squares 35a and 35b, and the contents inside the bag 1 are washed out from the sealing squares 35a and 35b.
5a, 3.5b from being contaminated or scorched, and in the case of a Teflon sheet containing glass fiber, a mesh or lattice shape is formed on the sealing surface to seal the bag 1.
It has a beautiful appearance of 41. However, each time the Teflon sheet 1-73 on the sealing surface becomes contaminated or scorched, it is necessary to pull out the roll of Teflon sheet 73 wound around the rod 70 and provide a new sheet surface, and each time the Teflon sheet 1-73 on the sealing surface becomes contaminated or scorched. The multi-row system has the disadvantage that the operation of the entire apparatus must be stopped, which consumes time.

In addition, if the seal angle 'rA' 35 a, 35b in which the seal angle and thermocouple are embedded in the car 1 is arranged in multiple rows, the device f becomes large and the structure becomes complicated, making maintenance and inspection difficult9:1f. was there.

- The required bath length of the Teflon sheet 180 between the feeding roll 178 and the winding roll 183 changes depending on when the bag is sealed (the state shown in FIG. 9) and when the bag is opened (the state shown in FIG. 12). However, the variable length is the same as that of the movable guide bar 1.
Absorbed by 91's 20 motions, Tef 1'n sheet 1

Move by <L, as shown in the figure. On the other hand, the seal Haza boats 151c, 126b, and 151a also have a drive shaft 153, a double-sided grooved cam 156, an upper lever 157, and a sleeve 159.
- The lower lever 164 is converted into a linear motion via the connecting member 165, and is moved by an amount L in the direction opposite to the transport direction of the bag 1 as shown in FIG. 15, and the upper opening of the bag 1 is opened as shown in FIG. is heat-sealed and cooled to solidify (at this time, the movable seal bar 1
16 is designed to bend the compression spring 119 by l as shown in FIG. 15).

Seal Harsabo) 126c, 1511), 126a and 151c, 126b, 151a are L in opposite directions.
Before moving forward, the bag 1 is moved upward while being held by a carrier (not shown) (Japanese Patent Application No. 58-107284).
It increases by 1 (Figure 9).

The difference between H and the distance between the upper end of the bag 1 and the lower end of the seal bar 144 before rising becomes the heat seal iJ.

After the predetermined time has passed, the sealper sabo) 126c
, 151.1), 126a and Seal Parsabo 1-1
51c, 126b, and 151a move in the opposite direction to open the bag 1. The above-mentioned operations are then repeated to sequentially heat-seal, cool and assimilate the bag 1. Next, the procedure for renewing the Teflon sheet 180 will be explained with reference to FIGS. 18 to 21.

In order to update the sealing surface from the state shown in FIG. 18 to a new sealing surface, rotate the winding roll 183 and wind up the tensile sheet 180 to a length of 2 m. As shown in FIG. 19, the new sealing surface (X part). Also, at the next update,
Similarly, by winding up a length of 2rn, a new sealing surface (0m portion) is created as shown in FIG. Next, at the time of the third update, the length is 14 m and the state shown in FIG. 18 is restored by winding it up, and subsequent updates can be made in the same manner.

Ju-IJ￥ As described in detail, the present invention provides means for preventing the saw bag from moving downward when held by a carrier, and a pair of seal bars in a direction perpendicular to the general feeding direction of the bag; Bag II
By configuring the feeding device with means that move forward and backward parallel to the feeding direction and in directions opposite to each other, it is possible to change to a multi-row single general feeding system with two or more rows without increasing the size of the device. In addition, the seal bar attached to the Seal Parthebo 1 was divided into a fixed beaver 1-bar in which a heat pipe, cartridge heater, and thermocouple were embedded, and a movable seal bar in which only the heat pipe was embedded. By using a method that heats the movable seal bar by heat conduction,
It becomes possible to adjust the temperature and surface pressure of the movable seal bar other than both ends. Furthermore, by burying the heat pipe,
A uniform temperature distribution in the lateral direction is achieved, and the sealing performance of the bag can be improved.

By setting a commercially available Teflon sheet between the winding roll for feeding out and the winding roll for winding up, it is possible to renew the new knoll surface even during operation without stopping the machine, significantly shortening the replacement time. It becomes possible. Note that it is also possible to automate the winding of the Teflon sheet using a motor or the like. On the other hand, fixed guide bar, sealper sabot 1-1
By setting the dimensional relationship of the FiJ moving guy 1 bar as shown in FIG. 18, the entire surface of the TEF I-J sheet can be used without wasting it, and the yield of the DEF I-J is improved. In addition, the cam followers at both ends of the seal bar Saho-1-
The seal bar support is supported by the rail, the driving force is transmitted through a connecting block fixed with bolts, etc., and the longitudinal positioning of the seal bar support is performed by the guide block in the center, the support plate, and the cam. By using a follower, it is possible to change the temperature based on the difference in set temperature (for example, 1st heat 1 - sole 1
80℃, 2nd heat 1-seal 150℃, cooling 40℃)
It is possible to absorb the difference in elongation of the seal bar support due to thermal expansion, and also the expansion and contraction of the individual sealer sabots 1 (for example, from room temperature to setting 180'cl volume temperature rise H4). In addition, in Fig. 22, by deleting the A'ζ bush 203 and changing the port 205 to a J bolt, the connecting bush 1! Also, the bag does not necessarily need to be conveyed in the thickness direction, but may be conveyed in the 111 direction.
