During the rotation from the position 56 to the position 57, the can mouth portion of the can C held by the can body holding means 10 at the position 56 is sealed with a lower portion of the filling valve 6 and centering and sealing described later. Thus, the filling liquid is filled from the filling valve 6.
Here, for convenience of explanation, the can SC will be described by first taking the case of filling the filling liquid containing gas.
When the can SC is filled with the gas-filled liquid, when the can SC comes near the position 56 shown in FIG. 1, the guide shaft 78 is engaged with a roller 78r and a bracket 78c, which are engaged and guided by a cam (not shown). When the centering bell 62 that moves down and moves together with the guide shaft 78 is lowered, the seal packing 62p comes into contact with the can opening SC1 of the container SC.

  As shown in FIG. 8, when the can mouth part SC1 and the seal packing 62p are brought into contact with each other, the can SC placed on the can base 14 is in a state of a body part SCb indicated by a two-dot chain line. When the center SCc of the SC and the center 6c of the filling valve 6 are not concentric (eccentric), the can SC is lightly sandwiched between the fixed acceleration arm 11 and the movable arm 21 of the can body holding means 10 as described above. Since the can mouth portion SC1 is brought into contact with and engaged with the inclined seal surface 62pa of the seal packing 62p, the arrow A along the inclined portion of the seal surface 62pa. The can SC is in the state of the body SCa indicated by the solid line, and the center SCc of the can SC and the center 6c of the filling valve 6 are centered in a concentric state.

  As described above, after the can SC is centered and the inside of the container SC is hermetically sealed by the seal packing 62p, the on-off valve 82v remains closed and the on-off valve 81v is opened for a predetermined time by a command from a control device (not shown). The pressure gas in the liquid tank (not shown) is supplied into the can SC through the gap 67c and the hole 67h. After the pressure in the can SC becomes the same as the gas pressure in the liquid tank, the pressure gas is supplied from a control device (not shown). , The on-off valve 81v is closed, the actuator 75 is actuated to raise the liquid valve 64, the liquid valve packing 64p is separated from the liquid valve seal surface 65s, and the filling liquid passage is opened as shown in FIG. When a predetermined amount of the filling liquid is filled in the can SC, the liquid valve 64 is closed by the operation of the actuator 75 according to a command from the control device, and the flow of the filling liquid is stopped. That.

After stopping the flow of the filling liquid into the can SC, the open / close valve 82v is opened by a command from a control device (not shown), and the pressure gas in the filled can SC opens the gap 67g, hole 67v, pipe 82, open / close After the inside of the filled can SC is at the same pressure as the atmosphere after being sniffed via the valve 82v, the guide shaft 78 ascends via the roller 78r due to the locus of the cam (not shown), and the centering bell 62 and the can SC The sealing seal with the can mouth portion SC1 is released, and the filling is completed.
As shown in FIGS. 5A and 5B described later, the can SC that has been filled is released from being held by the can body holding means 10.

  The above description has been given for the case of the can SC, but the same applies to the case where the can body diameter is an intermediate size between the can SC and the can LC. Similarly, when the center LCc of the can LC is slightly shifted from the center 6c of the filling valve 6 when being held by 10, the filling liquid is filled after being centered and hermetically sealed. Detailed description is omitted.

FIG. 5A shows a state immediately before the can SC after completion of filling by the filling valve 6 at the position 57 shown in FIG. 1 shifts from the holding state by the movable arm 21 to the open state, and FIG. 1 shows a state in which the can SC after completion of the filling is discharged to the conveyor 52 by the fixed acceleration arm 11 at a position 58 shown in FIG.
While the rotating disk 1R rotates from the position 57 to the position 58, the movable arm 21 swings from the closed to the open direction by the action of the roller 24 and the cam 26 against the action of the tension spring 30. The can SC is moved from the holding state to the open state, and the can SC is accelerated and discharged in the conveying direction of the conveyor 52 from the can barrel engaging portion of the fixed acceleration arm 11 at the position 58 shown in FIG.
5A and 5B, the two-dot chain line 14r and the two-dot chain line 52c indicate the rotation trajectory of the can 14 and the transport trajectory of the can SC on the conveyor 52, respectively. 14r shows a state offset from the two-dot chain line 52c.

In addition, since the pitch interval of the finger chain 52F is set larger than the pitch interval of the filling valve 6 of the can filling device 1, a device for adjusting the correlation of the pitch with the can filling device 1 in the seamer 53, that is, Adjustment is performed by an in-motion timer (not shown), but detailed description is omitted.
In the above description, the state where the can SC is held and opened in FIGS. 2 to 5 is explained. However, in the case of the can LC, or the can C between the minimum value and the maximum value of the can body diameter to be handled is the same. Since there is, overlapping description is omitted.
According to the present embodiment, the can body can be held corresponding to the can C of any body diameter from the can SC to the can LC, and the can C is moved to the conveyor 52 by the fixed acceleration arm 11. It can be accelerated and discharged.

In the above description, the case where the filling liquid filling the can C is a gas-containing filling liquid has been described, but the filling valve 6 can be applied even when the filling liquid is a gas-free filling liquid.
In this case, the opening / closing valve 81v is kept open, the centering bell 62 is lowered, and the can C is centered by the seal packing 62p in the same manner as in the case of filling the filling liquid containing gas. After sealing and sealing, when the liquid valve 64 is opened, the space on the liquid surface of the liquid tank (not shown) is at atmospheric pressure, so that the filling liquid is filled into the can C by gravity drop, and the inside of the can C Air is vented (discharged) to an upper space in a liquid tank (not shown) through the hole 67h, the gap 67c, the pipe 81, and the on-off valve 81v.

As for the filling of the gas-free filling liquid, the seal packing 62p may be filled without sealingly sealing the mouth of the can C depending on the kind of filling liquid and the kind of can (also referred to as non-seal filling).
At the time of non-seal filling, the roller 78r is not engaged with the cam (not shown), and the actuator 73 is operated to keep the centering bell 62 in the raised state via the plate 74 and the guide shaft 78. The filling liquid from the filling valve 6 to the can C is kept in the non-contact state (non-sealed state) between the lower part of the filling valve 6 and the mouth of the can C and without centering the center of the filling valve 6 and the center of the can C. Can also be filled.
As described above, in the can filling device of the present embodiment, the lower portion of the filling valve 6 and the mouth portion of the can C can be used for both the sealing filling in a contact state (sealed state) and the non-sealing filling.

  As described above, in the present embodiment, the compatibility between the can C and the can diameter of the can C from the can SC to the can LC, the compatibility with the type of the height of the can C, and the above Any type of can C can be used for filling liquids of gas-filled liquid and gas-free (non-gas) filling liquid, and can be used for both filling and non-sealing filling. Even if it is necessary to change the type of liquid, it can be filled without so-called remodeling, so that productivity can be greatly improved, and it is possible to cope with diversification of production forms and to have versatility.
