Description

Winding device

The present invention relates to a winding device including a chuck for winding a lid on a can and a cleaning unit for cleaning a seaming roll.

Conventionally, a can mounting unit for placing a can filled with a beverage or the like, a chuck unit provided facing the can mounting unit, and a winding device equipped with a seaming roll for winding a lid on a can have been used. It is known.
Known winding devices include, for example, a seaming turret (1) that performs a can and lid winding step, and a carry-in conveyor (supply) that supplies the can before winding to the seaming turret, as shown in Patent Document 1. Conveyor 7), the lid transport turret (supply turret 3) of the lid supply unit that supplies the lid, the discharge turret (discharge turret 5) that carries out the can after winding from the seaming turret, and the can further from the discharge turret. It is provided with a carry-out conveyor (discharge conveyor 8) for carrying out to the outside.
The seaming turret, the discharge turret, and the lid transport turret are each provided with pockets (fitting recesses 2, 4, 6) for individually accommodating and transporting the can and the lid on the outer peripheral portion.
In each pocket of the seaming turret, a can mounting unit (lifter 17) on which a can is placed, a chuck unit (seaming chuck device 10) provided facing the can mounting unit, and a lid are placed on the can. Seaming rolls (18, 19) for winding are provided.
In the winding device configured in this way, the speed and timing of each turret and each conveyor are adjusted by gears, etc., and the operation of the can mounting unit, chuck unit, and seaming unit arranged in each pocket is controlled by the gear and cam. By interlocking with the rotation of the seaming turret by a mechanism or the like, it is possible to continuously wind the can and the lid that are conveyed at high speed while delivering them.

In recent years, high-speed filling has become widespread in filling equipment for canned beverages, etc., and there is a demand for faster winding processing accordingly. Further, in a can filled with contents such as a beverage can, in order to prevent deterioration of freshness and flavor due to oxidation of the contents, a replacement gas is blown through a gap just before the lid covers the opening of the can to oxygen inside the can. Gas removal is being done. For these reasons, the contents are scattered from the can before winding, and dirt adheres to the side peripheral surface of the seaming roll. If this stain is left for a long period of time, it is not preferable in terms of hygiene such as the growth of germs, so regular cleaning and maintenance is required.

Further, a configuration having a plurality of chuck cleaning members 510, a configuration having a plurality of seaming roll cleaning members 520, and the like may be used. Further, the configuration may include a plurality of chuck cleaning members 510 and a plurality of seaming roll cleaning members 520.

The basic operation of the winding device 100 configured as described above will be described.
The can C before the lid F is wound is engaged with each attachment 103 of the carry-in conveyor 102 and conveyed, and heads toward the seaming turret 101 rotated by the drive mechanism 151 of the seaming turret 101.
On the other hand, the lid F is cut out one by one from the lid separation unit 210 and delivered to each pocket P of the lid transport turret 250, and is directed toward the seaming turret 101 by the rotation of the lid transport turret 250 (see FIG. 1).
The speed and timing of the carry-in conveyor 102 and the lid transport turret 250 are adjusted according to the speed and timing of the seaming turret 101 so that the centers of the can C and the lid F coincide with each other at the confluence point G. A can mounted on a plate 360 by raising a can mounting unit 350 whose rotation is controlled from a drive mechanism 151 to which power is applied from a source via an appropriate gear, a cam mechanism, etc. at a confluence point G. Place the lid F on C.
After that, the can mounting unit 350 is further raised, the knockout pad 322 in the chuck 321 presses the lid F, and the chuck 321 whose rotation is controlled from the drive mechanism 151 via an appropriate gear, cam mechanism, etc. is attached to the lid F. The can C is fitted and centered on the lid F, and the can C on which the lid F is placed is sandwiched between the plate 360, the chuck 321 and the knockout pad 322 with a constant axial load required for winding.
Then, the seaming turret 101 further rotates, and the plate 360 and the chuck 321 accelerate to the rotation speed required for winding before the sandwiched lid F and the can C reach the winding section E shown in FIG.
For primary winding, which is pivotally attached so as to swing the seaming lever 450 fixed to the lower end of the roll swing shaft 132 of the seaming unit 410 and rotate at both ends while passing through the winding section E. Double winding is performed by sequentially pressing two seaming rolls 451 and 452 for secondary winding from the side toward the chuck 321 against the flanges of the can C and the lid F placed on the can C. ..
The can CM that has been wound is delivered from the seaming turret 101 to the discharge turret 107, and further delivered from the discharge turret 107 to the unloading conveyor 108, and is carried out to the next process such as inspection and packing.

In the cleaning unit 500 of the present invention, when the cleaning mode is selected, the chuck unit 320 is revolved at predetermined intervals by the drive mechanism 151 of the seaming turret 101 based on the movement of the servomotor that rotates the chuck 321 ( It is stopped every 1 pitch). At this time, the chuck 321 of one chuck unit 320 is stopped at the first fixed cleaning position closest to the chuck cleaning member 510, and the seaming roll of the seaming unit 410 corresponding to the adjacent chuck unit 320. 451 and 452 are stopped at the second fixed cleaning position closest to the seaming roll cleaning member 520.
In the chuck unit 320 whose revolution is stopped at the first fixed cleaning position, the arm 517 of the chuck cleaning member 510 extends, and the movable unit including the chuck cleaning brush 511 advances in the direction from the outside toward the seaming turret 101. do. As a result, the chuck cleaning brush 511 is inserted between the two seaming rolls 451 and 452 related to the chuck unit 320, and the tip end portion thereof is pressed against the peripheral side surface of the chuck 321. After that, while the cleaning agent is injected from the nozzle 518, the chuck 321 is rotated by the drive mechanism 151 of the chuck unit 320 without revolving, and the peripheral side surface of the chuck 321 is cleaned by being rubbed by the chuck cleaning brush 511. NS.
In the seaming unit 410 whose revolution was stopped at the second fixed cleaning position, the arm 527 of the seaming roll cleaning member 520 was extended, and the movable unit including the seaming roll cleaning brushes 521 and 522 was seamed from the outside. Advance in the direction toward the turret 101. Then, the drive roller 529 simultaneously presses these seaming rolls 451 and 452, and the tips of the seaming roll cleaning brushes 521 and 522 are pressed against the peripheral side surfaces of the seaming rolls 451 and 452. After that, the seaming rolls 451 and 452 are driven by rotating the drive roller 529 while the cleaning agent is ejected from the nozzles 528 and 528, and the peripheral side surfaces of both seaming rolls 451 and 452 are the seaming roll cleaning brush 521. , 522 is rubbed to clean.
By repeating the above two types of cleaning operations over one revolution of the seaming turret 101, the chucks 321 related to each chuck unit 320 and the seaming rolls 451 and 452 of the seaming unit 410 are formed with the chuck cleaning member 510 and the seaming roll. It is sequentially cleaned by the cleaning member 520.
