Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a multi-lid seal for attaching a can lid to a can or a cap to a bottle after filling the can or bottle with contents, for example. It's about machines.

BACKGROUND ART Conventionally, for example, in a dual-purpose filling machine for filling cans and bottles with contents, a seamer for attaching a can lid and a cap for attaching a bottle cap are independently provided on the downstream side thereof.

Problems to be Solved by the Invention According to the above conventional configuration, since the seamer and the capacitor are provided independently, the installation area becomes large, and when one of them is operating, the other stops. However, it has poor operational efficiency and is expensive.

Means for Solving the Problem In order to solve the above problem, the multi-lid sealing machine of the present invention includes a fixed shaft, a lid sealing section and a rest section around the fixed shaft, and A turntable that rotates in one direction is provided, container mounting tables are arranged on the turntable at appropriate intervals in the circumferential direction so as to be able to be raised and lowered, and a fixed cam is provided in the lid sealing section to raise each container mounting table. A rotary tube is provided which is rotatably fitted onto the fixed shaft, a through hole at the base end is rotatably fitted onto the rotary tube, and a rotating body for cans is provided which has a plurality of can lid attachment devices at the tip. A connection in which a rotating body for a bottle is provided, the through-hole at the end is rotatably fitted onto the rotary cylinder, and the tip thereof has a plurality of bottle lid attachment devices, and one of the rotating bodies is connected to the rotary cylinder in the lid-sealing section. At the same time, a fixing device is provided to fix the other rotary body to the stationary body in the rest section, and a one-way clutch is provided to interlock the rotary cylinder only with the rotation of the turntable in one direction, and when the one-way clutch is released, A rotary cylinder drive device is provided for rotating the rotary cylinder by a predetermined angle in a direction opposite to that of the turntable.

In the above configuration, for example, when filling a can with contents, the can rotating body is brought to the lid sealing section and connected to the rotary cylinder by a coupling, and the other lid rotating body is brought to the resting section. It is fixed to a fixed body by a fixing device, and then the rotating cylinder is rotated in the same direction by the rotation of the turntable via a one-way clutch, and during this rotation, the can lid is double wrapped around the can by the rotating body for cans. After the work is completed, the rotary barrel drive device rotates the rotary barrel by a predetermined angle in the direction opposite to the turntable, thereby returning the can rotating body to the upstream end of the lid sealing section and sealing the can lid again. Perform installation work. Next, for example, when filling a bottle with contents, the bottle rotating body in the rest section is brought to the lid sealing section, and connected to the rotating cylinder by a connecting device,
Further, the rotating body for the can is brought to the rest area and fixed to the stationary body by a fixture, and then the bottle cap is attached to the bottle in the same procedure as for the can lid.

Hereinafter, the effects of the above configuration will be explained. First, when filling the can 1 with contents, the can rotating body 44 is brought to the position shown by B in the lid sealing section α, and the can rotating body 44 is moved by the connecting bolt 52.
4 is fixed to the lower end flange 53 of the elevating tube 41. Further, the bottle rotating body 55 is brought to the rest interval β and fixed to the fixed body 63 by the fixing tool 62. In this state, the empty can 1 sent in the direction of arrow (B) by the supply conveyor 10 is sent into the filling machine 3 by the inlet side star wheel 7 rotating in the direction of arrow (C), and the contents are filled into it. be done. The filled can 1 sent out from the filling machine 3 is sent into the sealing machine 6 by a transfer wheel 8 that rotates in the direction of arrow (D), and is transferred to each container mounting table of the turntable 28 that rotates in the direction of arrow (A). It is placed on 38. Also, the can lid 4 is supplied from the can lid supply device 13 to the upper opening of the can 1.
is supplied and fitted. Next, the container mounting table 38 supporting the can 1 with the can lid 4 fitted is moved in the direction of the arrow (A) by the turntable 28, and the cam roller 39 rides on the fixed cam 37, causing it to rise, and the three In the lid attaching device 48, the can lid 4 is double-sealed to the can 1 by a seamer roller 49 and a chuck 50, respectively. When the can rotation body 44 comes to the position shown by C in FIG. situation).
Then, the motor 36 rotates the rotating plate 20 in the opposite direction of the arrow (A) via the drive gear 33 and the circular arc gear 32. At this time, since the one-way clutch 30 is disengaged (connected state), the turntable 28
Although the rotating plate 20 continues to rotate in the direction of the arrow (A), the rotating plate 20 is allowed to rotate in the opposite direction of the arrow (A). Note that, prior to the rotation of the rotating plate 20 in the opposite direction of the arrow (A), the cam roller 39 is lowered from the upper surface 37A of the fixed cam 37, and the container mounting table 38 is lowered. When the can rotating body 44 is brought back to the position B in FIG. 2, the clutch 34 is released and the work of attaching the can lid 4 begins again. The can 1 sent out from the sealing machine 6 is conveyed in the direction of arrow (F) by the discharge conveyor 12 via the exit side star wheel 9 which rotates in the direction of arrow (E).

Next, when filling the bottle 2 with contents, the connecting bolt 52 is removed, the can rotating body 44 is brought to the rest zone β, and the bottle rotating body 55 is moved to the position shown by B in the lid sealing zone α. Then, the bottle rotating body 55 is fixed to the connecting plate 54 with the connecting bolt 61.
In this state, similarly to the case of the can 1, the empty bottle 2 is filled with the contents by the filling machine 3. A cap 5 supplied from a cap supplying device 14 is placed on the filled bottle 2 sent out from the filling machine 3. The bottle 2 with the cap 5 is placed on the container mounting table 38. Next, while the bottle rotating body 55 moves from the A position to the C position, the cap 5 is tightened onto the bottle 2 by the cap sealing head 58. Thereafter, it is transported in the same manner as can 1.

In addition, if it is necessary to adjust the height of each rotating body 44, 55, the handle 18C may be turned to move the elevator cylinder 41 up and down as appropriate.

Effects of the Invention As described above, according to the present invention, lids can be attached to cans and bottles after one unit is sealed, and the installation area is smaller than that of the conventional method.
High operating efficiency and low cost.
