and between a pair of horizontal heat sealing members 12, 12' provided below, respectively, and set to a lower position. Next, as shown in FIG. 5B, first, the pair of horizontal heat-sealing members 19, 19' to be temporarily heat-sealed are moved forward in the direction of the arrows, and the empty stake package 8 is clamped and pressed for temporary heat-sealing. At the same time, a pair of horizontal heat-sealing members 19, 19 temporarily heat-seal the solid filling 16, which is periodically taken out from the rotary weighing machine 17, with most of it inside the cylindrical wall 5. ' causes a temporary stop. At this time, a pair of horizontal heat-sealing members 12, 12' located at a lower position also operate at a predetermined lower position to press and clamp the stake package 8 at a predetermined location. Next, as shown in FIG. Part 1
2 and 12' downward, and the stick package 8 is moved downward by a required length (one bag), as shown in FIG. 5D. The moment the stick package 8 is moved to the predetermined lower position, the cut member 14, which is interlocked with the horizontal heat seal members 12, 12', is operated to cut off the lowermost portion of the stick package 8. This cut staple package 8 is an empty bag that is not filled with solid filler. In FIGS. 5C and 5D, the pair of horizontal heat-sealing members 19 and 19' for temporarily heat-sealing remain released from pressing and holding the stake package 8. When the cutting operation by the cutting member 14 is completed, as shown in FIG. 5E, a pair of horizontal heat sealing members 19 and 19' for performing temporary heat sealing are moved forward in the direction of the arrow as in the case shown in FIG. 5B. When activated, the stick package 8 is clamped and pressed, and at the same time, the solid filling 16 is
The filling of one bag is temporarily stopped by a pair of horizontal heat sealing members 19, 19' which supply the liquid into the cylindrical wall body 5 and perform the temporary heat sealing. At this time, the horizontal heat-sealing members 12, 12' and the cut member 14, which are already in the lower position, return to their original positions, and this pair of horizontal heat-sealing members 12, 12' are attached to the previously temporarily heat-sealed stake package 8. A predetermined location is pressed and held.

It is adjusted and positioned at approximately the uppermost end of the solid filler 16 filled in the stick package 8. Next, as shown in FIG. While moving the sealing members 12, 12' downward and pressing and clamping the temporarily heat-sealed portion of the stick package 8 to heat-seal (in some cases, the sealing effect may be improved by cooling after heat-sealing), The stick package 8 is moved downward by a required length (one bag). Then, the moment the horizontal heat sealing members 12, 1 are transferred to a predetermined position,
The cutting member 14 interlocking with the stick package 2' is operated to cut off the lower part 8'' of the stick package 8. In this case as well, the cut off stick package 8'' has the solid filler 16. Although it is an empty bag that has not been filled, as the operation is continued one after another, the stay package 8'' filled with the solid filler 16 will be cut off, and the temporary heat seal will be cut off. A pair of horizontal heat sealing members 1
9 and 19', the height and thickness detecting means component 22 attached thereto for detecting the filling height and thickness of the solid filler 16 in the stick package 8 is activated. The amount is to be detected. That is, when the solid filler 16 is filled in a fixed amount, the detection rod 25 constituting the detection means component 22 moves to the right in FIG. 4 while compressing the spring 27 due to the resistance of the solid filler 16. , one end of the detection rod 25 is connected to the detection member 26
By detecting this, it is possible to display and confirm that quantitative filling has been carried out using an appropriate display means (not shown), and if the bag is empty or the amount of filling is small, the detection Since the resistance to the rod 25 is weak and the detection rod 25 does not move to the right in FIG. 4 and the detection member 26 does not operate, abnormalities in the filling of the solid filling are appropriately displayed and confirmed by the display means. It is something.

【Effect of the invention】

By configuring as described above, the present invention provides a pair of horizontal heat-sealing means for temporarily heat-sealing, which is provided immediately below the cylindrical wall, to hold the solid filling filled into the cylindrical bag. A receiving member and a detecting rod which can move forward and backward with respect to the receiving member by means of a spring are attached through almost the top end portion, and the height of the solid filling inside the cylindrical bag and the filling height of the solid filling in the cylindrical bag are measured in the forward and backward direction of the sensing rod. Since a mechanical detection member consisting of a sensor such as a proximity switch is attached to simultaneously detect the thickness, the pair of horizontal heat sealing means temporarily heat seals the cylindrical bag and at the same time the mechanical detection member Since the height and thickness of the solid filling inside the cylindrical bag can be detected simultaneously, the cylindrical bag can be made of either transparent or opaque materials such as plastic film or paper. Generally, the material is not limited in any way, and the filling amount of solid filler can be measured during the packaging process of filling a cylindrical bag with a predetermined amount of solid filler, and the detection means By making it possible to change the installation position of the cylindrical bag along the transport direction of the cylindrical bag, when the height of the solid filling to be filled into the cylindrical bag changes, that is, the filling amount can be changed. Even if the filling amount is the same, the filling amount can be measured accordingly, and it can be detected and displayed to confirm whether or not the filling amount satisfies the specified amount. It is possible to easily, quickly and reliably determine the quality of a fixed-quantity filling package (empty bag, small amount of filling, etc.) without any restrictions during the constant flow of filling and packaging. It has the advantage of being able to perform work with high efficiency.
