Description

Rolling device

The present invention relates to a crimping device with a cleaning unit, wherein the cleaning unit cleans a rolling head and a crimping roller for crimping a can cover onto a can body.

Previously, a kind of rolling and sealing device has been known, which is equipped with: a can body loading unit, which carries a can body filled with beverages, etc.; a roller head unit, which is arranged to be opposite to the can body loading unit; and a can sealing roller, which rolls the can lid onto the can body. For example, as shown in Patent Document 1, a well-known crimping device is provided with: a can crimping turntable (1) for crimping cans and can lids; an infeed conveyor belt (supply conveyor belt 7) for supplying cans before crimping to the can crimping turntable; a can lid conveyor turntable (supply turntable 3) of a can lid supply unit for supplying can lids; a can discharge turntable (discharge turntable 5) for discharging the crimped cans from the can crimping turntable; and a discharge conveyor belt (discharge conveyor belt 8) for further discharging the can bodies from the can discharge turntable to the outside. Pockets (engaging recesses 2, 4, 6) that can accommodate and transport can bodies and can lids individually are provided on the outer periphery of each of the can sealing turntable, the can unloading turntable, and the can lid conveying turntable. In each of the pockets of the can sealing turntable, there are: a can body loading unit (can lifter 17) for loading the can body, a roller unit (can sealing roller device 10) that is arranged opposite to the can body loading unit, and a can sealing roller (18, 19) that rolls the can lid onto the can body. In the above-mentioned rolling and sealing device, the speed and timing of each turntable and each conveyor belt are made consistent by gears, etc., and the movement of the can body loading unit, roller head unit and can sealing unit arranged in each groove is linked with the rotation of the can sealing turntable by gears, cam mechanisms, etc., so that the can bodies and can lids being transported at high speed can be continuously rolled and sealed.

In recent years, high-speed filling is widely used in equipment for filling canned beverages, and correspondingly, there is a demand for high-speed rolling processing. In addition, in order to prevent the freshness and flavor of the can body filled with contents such as beverage cans from deteriorating due to oxidation, before the can lid is covered on the opening of the can body, replacement gas is blown into the gap to remove the oxygen inside the can. Due to such operations, the contents fly out of the can body before rolling, and dirt adheres to the side surface of the canning roller. If the dirt is left for a long time, bacteria will multiply and the hygiene will be poor, so regular cleaning and maintenance are required. [Prior technical literature] [Patent literature]

(Invent the problem you want to solve)

The can sealing roller of the crimping device revolves along with the can sealing turntable, and at the same time, it rotates in coordination with the rotation of the roller head of the roller head unit that revolves simultaneously through the can body and the can lid. Therefore, there are the following problems: when there is no can body and can lid, the roller head cannot rotate, and when cleaning and sterilizing the can sealing roller, the operation of the crimping device must be stopped, and the can sealing roller must be rotated manually for cleaning, so cleaning is more laborious. In addition, there are the following problems: the roller head is located further inside the can sealing roller when viewed from the outside, and it is difficult for the cleaner to reach it. Moreover, if the roller head is rotated to clean the entire circumference of the side surface, the can sealing turntable connected by the gear must be rotated. Furthermore, in the present invention, the so-called can sealing turntable is used for the rolling and sealing step of rolling the can lid onto the can body. In general, it refers to the following components in this step: a loading unit for loading the can body that is rotated integrally, a roller head unit for positioning the can lid onto the can body, a moving turntable with a groove for supporting the can body, a can sealing unit for rolling the can lid onto the can body, and a shell containing the same.

In the roller head cleaning member 510, the roller head cleaning brush 511 and the nozzle 518 are integrally provided as a movable unit that can move forward and backward by means of an arm 517. The movable unit of the roller head cleaning member 510 is provided to move forward and backward along the radial direction of the central axis X of the canning turntable 101, specifically, along the direction from the outside toward the adjacent canning rollers 451, 452.

The can-sealing roller cleaning component 520 has a driving roller 529 and can-sealing roller cleaning brushes 521, 522. The driving roller 529 can be pressed against both adjacent can-sealing rollers 451, 452, and the can-sealing roller cleaning brushes 521, 522 can abut against each of the two can-sealing rollers 451, 452. As shown in FIG5, the can-sealing roller cleaning component 520 has an arm 527, and the driving roller 529 composed of a roller brush, a rubber roller, etc. is fixed at the front end of the arm 527. As shown in Fig. 6, the driving roller 529 is arranged to rotate around an axis parallel to the rotation axis of the canning rollers 451, 452 by means of an electrically or pneumatically driven motor 523. An arm 527 is arranged at the lower part of a supporting part 526 so as to be retractable along the advancing and retreating direction of the movable unit, and the upper part of the supporting part 526 is fixed to the fixed part, i.e., the inner casing, by means of a bolt 525. The sealing roller cleaning brushes 521 and 522 are in contact with the peripheral surfaces of the sealing rollers 451 and 452 rotated by the driving roller 529, and have the same flat, roughly rectangular shape as the roller cleaning brush 511 of the roller cleaning member 510, and are arranged in a posture extending in an inclined direction relative to the forward and backward direction of the movable unit. In addition, a nozzle 528 for spraying a cleaning agent on the cleaning area is provided on the side of the sealing roller cleaning brushes 521 and 522.

The crimping device 100 of the present invention has a cleaning control mechanism. When the cleaning mode is selected, the revolution of the canning turntable 101 performed by the roller head unit 320 is stopped, and when the roller head 321 of the roller head unit 320 is set to be rotatable, the following cleaning actions are performed: the roller head cleaning component 510 including the movable unit of the roller head cleaning brush 511 and the canning roller cleaning component 520 including the movable unit of the canning roller cleaning brushes 521 and 522 automatically move forward toward the canning turntable 101 along the forward and backward direction of the cleaning component. The following control is performed in the cleaning control mechanism: the cleaning action is performed at a predetermined interval of each revolution of the roller unit 320 performed by the canning turntable 101. Specifically, the cleaning action is performed at each pitch of the roller 321 by the servo motor that rotates the roller 321.

In the present embodiment, an example of having two cleaning components (a roller head cleaning component 510 and a canning roller cleaning component 520) has been described, but the present invention does not exclude an example of having only a roller head cleaning component 510 or a canning roller cleaning component 520. In addition, it may also be a configuration having a plurality of roller head cleaning components 510, or a configuration having a plurality of canning roller cleaning components 520. Furthermore, it may also be a configuration having a plurality of roller head cleaning components 510 and a plurality of canning roller cleaning components 520.

The basic operation of the sealing device 100 constructed as above is described below. The can body C before the can cap F is sealed is engaged with each attachment 103 of the conveyor belt 102 and is transported toward the can sealing turntable 101 which is rotated by the driving mechanism 151 of the can sealing turntable 101. On the other hand, the can cap F is cut out piece by piece from the can cap separation unit 210, and then transferred to each groove P of the can cap conveying turntable 250, and is directed toward the can sealing turntable 101 by the rotation of the can cap conveying turntable 250 (refer to Figure 1). The speed of the conveyor belt 102 and the can lid conveying turntable 250 is adjusted in time with the speed of the can sealing turntable 101 in such a way that the centers of the can body C and the can lid F coincide at the confluence point G, and the driving mechanism 151 which obtains power from the driving source (not shown) rotates the controlled can body loading unit 350 through appropriate gears, cam mechanisms, etc., and rises at the confluence point G, thereby loading the can lid F on the can body C loaded on the flat plate 360. Afterwards, the can body loading unit 350 is further raised, and the ejection pad 322 in the rolling head 321 presses the can cover F, so that the driving mechanism 151 rotates the controlled rolling head 321 through appropriate gears, cam mechanisms, etc., and engages with the can cover F, and performs the center correction of the can cover F. The can body C carrying the can cover F is clamped by the flat plate 360, the rolling head 321 and the ejection pad 322 using the predetermined axial load required for rolling. Then, the canning turntable 101 is further rotated, and before the clamped can lid F and can body C reach the rolling section E shown in FIG. 1 , the flat plate 360 and the roller head 321 are accelerated to the number of rotations required for rolling. During the process of passing through the rolling section E, the canning unit 410 is fixed to the lower end of the roller swing shaft 132. The rolling rod 450 is swung, and the two canning rollers 451 and 452 for primary and secondary rolling, which are pivoted at both ends for rotation, are pressed against the flanges of the can body C and the can lid F placed on top of it from the side toward the roller head 321, thereby performing double rolling. The rolled can body CM is transferred from the can-sealing turntable 101 to the can-discharging turntable 107, and then transferred from the can-discharging turntable 107 to the carrying-out conveyor belt 108, and is carried out to the next step of inspection, packaging, etc.

In the cleaning unit 500 of the present invention, when the cleaning mode is selected, the revolution of the roller head unit 320 performed by the driving mechanism 151 of the canning turntable 101 is stopped at each predetermined interval (each pitch) based on the action of the servo motor that makes the roller head 321 rotate. At this time, the roller head 321 of one roller head unit 320 stops at the first fixed cleaning position closest to the roller head cleaning component 510, and the canning rollers 451 and 452 of the canning unit 410 corresponding to the adjacent roller head unit 320 stop at the second fixed cleaning position closest to the canning roller cleaning component 520. In the roller head unit 320 whose revolution is stopped at the first fixed cleaning position, the arm 517 of the roller head cleaning member 510 is extended, so that the movable unit including the roller head cleaning brush 511 moves forward from the outside toward the canning turntable 101. Thereby, the roller head cleaning brush 511 is inserted between the two canning rollers 451 and 452 of the roller head unit 320, and its front end is pressed against the peripheral surface of the roller head 321. Thereafter, while the cleaning agent is sprayed from the nozzle 518, the driving mechanism 151 of the roller head unit 320 causes the roller head 321 to rotate without orbiting, so that the roller head cleaning brush 511 slides and rubs the peripheral surface of the roller head 321, thereby cleaning. In the canning unit 410 whose orbit is stopped at the second fixed cleaning position, the arm 527 of the canning roller cleaning component 520 is extended, so that the movable unit including the canning roller cleaning brushes 521 and 522 moves forward from the outside toward the canning turntable 101. Then, the driving roller 529 presses the sealing rollers 451 and 452 at the same time, and the front ends of the sealing roller cleaning brushes 521 and 522 are pressed against the peripheral surfaces of the sealing rollers 451 and 452. Afterwards, while the cleaning agent is sprayed from the nozzles 528 and 528, the sealing rollers 451 and 452 are driven by rotating the driving roller 529, so that the sealing roller cleaning brushes 521 and 522 slide and rub against the peripheral surfaces of the two sealing rollers 451 and 452 to clean them. By repeatedly performing the above two cleaning actions within one revolution of the canning turntable 101, the roller head cleaning component 510 and the canning roller cleaning component 520 can sequentially clean the roller heads 321 of the roller head units 320 and the canning rollers 451 and 452 of the canning unit 410.
