A device 36, a top heater device 37 for heating the upper part 7, and a top press device 38 for sealing the second part 7 are arranged, and the completed carton 2 is discharged from the three discharge devices.

The spout inserting device 30 takes out the spout 9 at the most distal end of the spout conveying chute 66 from among the spouts sequentially passed through the spout conveying chute 66 from the spout supply unit, and inserts the spout 9 into the carton 2. It is configured to be inserted into a plug-fitting press hole 2a previously bored in the upper wall surface from the mountain side. Note that the spout 9 may be inserted from the outside. The carton 2 into which the spout 9 has been fitted is welded with the spout 9 by a spout welding device 31 .

This spout welding device 31 ultrasonically welds the mutually opposing surfaces of the flange of the spout 9 and the opening edge of the spout insertion hole. In this plug welding device 31, there is a risk that foreign matter such as waste may adhere to the inside of the carton 2. A cleaning device 33 is then provided to remove this foreign material.

As shown in FIG. 4, this cleaning device 33 has a blow pipe having an injection hole on the outside of the lower end for ejecting air injected from an air inlet 50, and a suction port for sucking foreign matter at the lower end.
A cleaning pipe 11 made of a double pipe with a suction pipe on the saw side is provided. These blow pipes and suction pipes may be connected to an air seat height and a vacuum pressure source through appropriate control valves, respectively. Further, this cleaning device 33 includes a cleaning pipe elevating means that lowers the cleaning pipe 11 and enters the cleaning pipe into the carton from the upper opening of the carton 2 when the carton 2 is positioned directly below the cleaning pipe 11. 12.

Since this elevating means 12 is driven by the drive source of the conveying device, the structure of the entire filling and sealing machine becomes simple and its control becomes easy.

This cleaning pipe 11 is supported via a bracket 70 fixed to a rod 13 constituting the elevating means 12, and is raised and lowered by the vertical movement of this rod 13. The range of elevation of this clean pipe 11 is as follows:
The position of the bracket 70 can be shifted and adjusted.

When the cleaning pipe 11 having a double pipe structure is lowered by the lifting means 12, air is injected onto the inner wall surface of the carton 2 from an injection port formed at the lower end of the outer passage of the blow pipe. Paper powder etc. blown up by this jet,
Since it is immediately sucked up by a suction pipe having a suction port at the lower end of the inner passage of the cleaning pipe 1.1, there is no fear that heavy paper dust and the like will remain at the bottom of the carton.

When the inside of the carton 2 has been cleaned, the air injection and suction of foreign matter are temporarily stopped, and the cleaning pipe 11 is lifted up by the elevating means 12. By the above-described operation, it is possible to efficiently remove odors and the like that adversely affect the quality of the material to be filled.

In the above-mentioned cleaning process, air can be injected from the blow pipe and at the same time foreign matter can be suctioned by the suction pipe only during the process in which the cleaning pipe 11 is placed in the carton 21 and raised. Further, in the process 1 of ascending and descending, the cleaning pipe 11 is inserted into the carton 2, and while descending, injects air from the blow pipe, and at the same time suctions foreign matter with the suction pipe, and while ascending, air is sucked out from the blow pipe. While spraying, you can also use the suction pipe to suck up foreign objects at the same time.

The cleaning device 33 can be placed between a first top breaker device 34 and a contents filling device 35, which will be described later, but if it is placed after the first top breaker device, it will clean the inside of the folded carton. It may be difficult to clean the wall surface in the shadow, and there is also a risk of damaging the top of the carton when inserting the cleaning pipe 11. Therefore, as described above, it is necessary to place the cleaning pipe 11 in front of the first top breaker device 34. It is preferable to do so.

This folding member 120 is connected to a block 73 via a suitable link 74, and this block 7
When the carton 3 and the frame 72 are lowered, they fall inward, and the opening at one end of the carton 2 is once folded into a roof shape along the ruled lines to form a crease. The carton 2 whose upper part has been temporarily folded is gradually restored due to its rigidity and is moved to the official goods filling device 35 (c).

This content filling device 35 has a filling tank 10 for storing content, and two filling nozzles 80 extending from this filling tank 10. When the carton 2 is positioned directly below these filling nozzles 80, the two nozzles simultaneously fill the insides of separate cartons 2 with the materials to be filled.

Since two cartons 2 can be filled at the same time, a predetermined amount of material to be filled can be poured into the cartons 2 even during a short stoppage time.

As a filling method, first half of the material to be filled is injected into the carton 32 using the filling nozzle 80 located on the upstream side when viewed from the carton conveyance path. Subsequently, the filling nozzle 80 located on the downstream side injects the remaining half of the material into the carton 2 into which half of the material has been filled, thereby completing the filling operation.

The carton 2 filled with the material to be filled is then
It is conveyed to the top breaker device 36.

The transported carton 2 is again pushed inward by a pair of folding members 121 connected to the frame 84 through the inwardly folded portion of the upper end opening of the carton 2 along the ruled line. The carton 2 that has been temporarily folded again is then conveyed to the top heater device 37 in order to complete the carton 2 called a Goebel top.

This top heater device 37 includes a block 85 having a pair of heater parts 85a, each heater part 85a is interposed in the upper end opening of the carton 2, and heats the resin layer around the upper end opening. The heated carton 2 has a pair of blocks 123 (see FIG. 3) that presses the top end of the carton 2, and a pair of claw members 122 that bends the side surface of the top of the carton 2 adjacent to the spout 9 inward. It is transported to a top press device 38 equipped with. When the top press device 38 descends onto the carton 2, the claw side 122 bends the side surface of the upper part of the carton 2 inward, and at the same time, the block 12B firmly connects the upper end of the carton. The completely sealed carton 2 is discharged from three ejection devices (see FIG. 1).
