The present invention relates to a seaming apparatus, which comprises: a chuck to crimp the lid to the can; and a cleaning unit that cleans the hemming-joining roller.
Background
Conventionally, a seaming apparatus is known which includes: a can placing unit for placing a can filled with a beverage or the like; a chuck unit disposed opposite to the can placing unit; and a seaming roll that crimps the lid to the can.
For example, as shown in patent document 1, a known seaming apparatus includes: a seaming turntable (1) for seaming the can and the lid; a carry-in conveyor (supply conveyor 7) that supplies cans before seaming to the seaming turret; a cap conveying turntable (supply turntable 3) of a cap supply unit for supplying caps; an unloading turntable (discharge turntable 5) for carrying out the seamed cans from the seaming turntable; and a carrying-out conveyor (discharge conveyor 8) for carrying out the cans further from the unloading turret to the outside.
The seaming turret, the unloading turret, and the lid conveying turret are provided with recesses (fitting recesses 2, 4, and 6) for individually accommodating and conveying the cans and the lids, respectively, on the outer peripheral portions thereof.
Each recess of the hemming-joining turntable is provided with: a tank mounting unit (elevator 17) on which a tank is mounted; a chuck unit (seaming chuck device 10) provided to face the can loading unit; and seaming rollers (18, 19) that seam the lid to the can.
In the seaming apparatus configured as described above, the speeds of the turntables and the conveyors are made to correspond to each other by gears or the like, and the operations of the can placing unit, the chuck unit, and the seaming unit disposed in the pockets are linked to the rotation of the seaming turntables by gears, cam mechanisms, or the like, whereby the seaming can and the lid conveyed at high speed can be continuously performed while being delivered.
In recent years, filling equipment for canned beverages and the like has been widely used for high-speed filling, and accordingly, there is a demand for high-speed seaming. In order to prevent deterioration in freshness and flavor due to oxidation of contents, a can such as a beverage can is filled with the contents, and oxygen in the can is removed by blowing a replacement gas through a gap immediately before the lid covers the opening of the can. Therefore, the content is splashed from the can before seaming, and dirt adheres to the side peripheral surface of the seaming roll. If the dirt is left for a long time, it is not preferable from the viewpoint of hygiene such as propagation of germs, and regular cleaning and maintenance are required.

The speed and timing of the carry-in conveyor 102 and the lid conveying turret 250 are adjusted in accordance with the speed and timing of the hemming-joining turret 101 so that the centers of the cans C and the lids F coincide at a junction point G, and the can placing unit 350 whose rotation is controlled by a drive mechanism 151 to which power is applied from a drive source, not shown, via an appropriate gear, cam mechanism, or the like is raised to the junction point G, thereby placing the lids F on the cans C placed on the plate 360.
Then, the can placing unit 350 is further raised, the push-out pad 322 in the chuck 321 presses the cap F, the chuck 321 whose rotation is controlled from the driving mechanism 151 is fitted to the cap F through an appropriate gear, a cam mechanism, or the like to center the cap F, and the can C on which the cap F is placed is clamped by the plate 360, the chuck 321, and the push-out pad 322 with a constant axial load required for seaming.
Further, the seaming turret 101 is further rotated, and the plate 360 and the chuck 321 are accelerated to a rotation speed necessary for seaming before the clamped lid F and can C reach the seaming zone E shown in fig. 1.
While passing through the seaming zone E, the seaming lever 450 fixed to the lower end of the roller swing shaft 132 of the seaming unit 410 is swung so that 2 seaming rollers 451, 452 for 1-time seaming and 2-time seaming pivotally mounted at both ends respectively are sequentially pressed against the flanges of the can C and the lid F placed thereon from the side toward the chuck 321, thereby performing double seaming.
The seamed cans CM are delivered from the seaming turret 101 to the unloading turret 107, and further delivered from the unloading turret 107 to the carry-out conveyor 108, and are carried out to subsequent processes such as inspection and bundling.
When the cleaning mode is selected, the cleaning unit 500 of the present invention stops the revolution of the chuck unit 320 by the driving mechanism 151 of the hemming-joining turntable 101 at predetermined intervals (at 1 pitch) based on the operation of the servo motor that rotates the chuck 321. At this time, the chucks 321 of 1 chuck unit 320 are stopped at the 1 st fixed cleaning position closest to the tool cleaning member 510, and the hemming roller 451, 452 of the hemming roller 410 corresponding to the adjacent chuck unit 320 are stopped at the 2 nd fixed cleaning position closest to the hemming roller cleaning member 520.
With respect to the chuck unit 320 which stops its revolution at the 1 st fixed cleaning position, the arm 517 of the chuck cleaning member 510 is extended, and the movable unit including the chuck cleaning brush 511 is advanced and retreated in a direction from the outside toward the hemming-joining turntable 101. Thereby, the chuck cleaning brush 511 is inserted between the 2 crimping rollers 451, 452 relating to the chuck unit 320, and the tip end portion thereof is pressed against the peripheral surface of the chuck 321. Then, the cleaning agent is ejected from the nozzle 518, and the chuck 321 is rotated by the drive mechanism 151 of the chuck unit 320 without revolving, and the peripheral surface of the chuck 321 is cleaned by sliding friction with the chuck cleaning brush 511.
With respect to the hemming-engagement unit 410 that stops its revolution at the 2 nd fixed washing position, the arm 527 of the hemming-engagement roller washing member 520 is extended, and the movable unit including the hemming-engagement roller cleaning brushes 521 and 522 is moved in and out in a direction from the outside toward the hemming-engagement turntable 101. The drive roller 529 simultaneously presses the crimping roller 451, 452, and the tip end portions of the crimping roller cleaning brushes 521, 522 are pressed against the peripheral surfaces of the crimping roller 451, 452. Then, the cleaning agent is ejected from the nozzles 528 and 528, and the drive roller 529 is rotated to drive the hemming-engaging rollers 451 and 452, and the peripheral side surfaces of the both hemming-engaging rollers 451 and 452 are cleaned by sliding friction with the hemming-engaging roller cleaning brushes 521 and 522.
By repeating the above-described 2 kinds of cleaning operations while the hemming turntable 101 revolves for 1 revolution, the chucks 321 of the chuck units 320 and the hemming rollers 451, 452 of the hemming unit 410 are cleaned in order by the chuck cleaning member 510 and the hemming roller cleaning member 520.
