Description

  The present invention relates to a method of connecting a bottle and can filling device and a lid clamping device, and a container filling lid clamping device, and more particularly to a rotary liquid filling machine (filler) and a capper or seamer as a lid clamping device. This is related to the formation (arrangement) of the transport. In the present invention, the bottle a has a mouth portion for screwing or plugging a cap whose diameter is reduced from the body portion, and is a synthetic resin bottle blow-molded using a resin material such as a metal bottle or polyethylene terephthalate. Or glass bottles. The can b includes a beverage can filled with a beverage, a can filled with food and seasonings, and the like.

Recently, it is desirable to process cans of different sizes or bottles and cans with a common filler (filler) in order to improve the efficiency and space saving of the apparatus. Further, there is a demand for conveyance to a capper (cap screwing and forming machine) or lid tightening machine (seamer).
Conventionally, containers that are used in storage containers for beverages, etc., are mass-produced and distributed in the market, have a diameter that is significantly reduced in diameter from the trunk, and have a mouth for screwing or molding or plugging the cap. There are glass bottles called bottles and synthetic resin bottles that are blow-molded using resin materials such as polyethylene terephthalate and are mainly called PET bottles.
In the production line for beverages, glass bottles are transported from the filling device to the capping device mainly by pushing or sucking the body or bottom of the container with a transport device etc. For the purpose of preventing breakage or the like, not so high speed conveyance is required. Further, in modern synthetic resin bottles, due to the strength property of the thinned container body, it has become the mainstream to grasp the neck and convey it along a continuous circular path.
On the other hand, there is a metal can which is mainly called an aluminum can or a steel can, and does not have a mouth portion whose diameter is significantly reduced from that of a barrel portion for screwing or molding or plugging a cap.
Cans are transported at high speed in the production line for beverages, etc., from the filling device to the lid tightening device with a dog chain called a hook-up chain at the bottom or body, corresponding to the required production volume. .
In recent years, metal bottles called bottle cans have been developed and are beginning to be adopted, which have a mouth part that is molded from aluminum and steel materials used in canned cans and beverage cans and has a diameter that is significantly smaller than the body part. .

The assignee of the present invention has already disclosed Japanese Patent Publication No. 3-39916 as a rotary liquid filling apparatus that processes containers of different sizes with a common filling machine (filler) and transports them to a plurality of lid wrapping machines (seamers). Invented the issue. Japanese Patent Laid-Open No. 2003-200997 has already been invented as such a bottle conveying device. Japanese Patent Laid-Open No. 8-229625 discloses such a can and lid transport device.
Further, Japanese Patent Application Laid-Open No. 2001-122433 discloses that a container having a circular cross section is shifted from a circular orbit without causing an impact on a linear orbit.

Japanese Patent Publication No. 3-39916 JP 2003-200997 A JP-A-8-229625 JP 2001-122433 A

However, although the above Japanese Patent Publication No. 3-39916 is sent from the filling machine 1 to the different container processing devices 6 and 6 'by the carry-out conveyor 5 or 5', the amount of the filling machine can be reduced due to the arrangement. A large installation area is required, and the carry-out conveyor 5 or 5 'has disadvantages such as requiring a drive system. Furthermore, when the conveyor 5 is selected depending on the filling conditions, the filling machine 1 may not have a sufficient filling angle, and the object of the invention may not be achieved.
The above Japanese Patent Application Laid-Open No. 2003-200997 discloses a technology of a rotary bottle transport device that grips and transports a neck portion of a bottle along a continuous circular trajectory. If it is required to transport at the same high speed as a can in order to meet the required production volume, it cannot be applied due to its structure, and the filling device is transported by the filling pitch of the filling valve or filling nozzle. If the pitch does not match the transport pitch of the capping device due to the mounting pitch of the capping head such as the capping head or the sealing head, it cannot be adapted due to its configuration.
Japanese Patent Application Laid-Open No. 8-229625 suggests a technique for preventing a shock at a gassing turret in a container closing machine. However, the technique seams the feed pitch of a can in a can lid clamping machine. It is a technology to match the head pitch, and it is not sufficient and cannot be applied to a bottle cap tightening machine generally called a capper that does not have a gassing turret for feeding a can lid.
Japanese Patent Laid-Open No. 2001-122433 discloses a conveying method for transferring a circular cross-section container from a circular orbit to a straight orbit, and it is preferably employed at the filling machine outlet also in the practice of the present invention. .

The present invention solves such a problem, and uses a bottle container as a can beverage production line and extends linearly from a filling device to a lid tightening device. The bottom or body of the container is a dog chain called a hook-up chain. By connecting with a carry-out conveyor that is transported at a high speed, the take-out device can take out containers to the lid-clamping machine while changing to a suitable conveyance pitch even from a carry-out conveyor with a different pitch and conveyance pitch of the lid-clamping device. Thus, it is possible to connect a plurality of capping machines having different transport pitches to a single carry-out conveyor due to the convenience of production line equipment, and to provide an efficient and space-saving container capping device. .
In addition to the can lid that is wrapped around the can body by a seamer, the lid is formed with a metal roll-on cap that engraves a screw with a roller when the lid is tightened along the screw formed on the bottle. Caps, crowns, stoppers, etc. made of synthetic resin, etc. can be mentioned, but there are a sealing machine, a capping machine, a crowner, a plugging machine, etc. as each of the lid clamping devices or lid clamping machines.

A bottle a or can b is fed from a supply conveyor 2 to a filling machine 1, and a straight line is provided at the outlet of the filled bottle a or can b. A carry-out conveyor 3 provided with a dog chain 3a that regulates and conveys the conveyance interval of the containers extending in a shape, and the capper 4 of the bottle a is disposed in the middle of the carry-out conveyor 3 provided with the dog chain 3a extending in a straight line, Further, a lid baffle 5 for the can b is disposed at the end of the carry-out conveyor 3 provided with the dog chain 3a.

  A take-out device 8 is arranged at a branching portion 9 between the dog chain 3a and the capper 4. The take-out device 8 is provided with a take-out turret 10 and a receiving turret 11. The take-out turret 10 is provided so as to be freely disengaged from the container fed by the dog chain 3a.

  The take-out turret 10 of the take-out device 8 has a shape that pushes the bottle a with a surface that does not give an impact to the container of the bottle a, that is, a curved surface that gives a continuous mountain-shaped acceleration, Above them, guides 13, 14 that are curved toward the receiving turret 11 in the direction of travel are provided.

Next, the take-out device 8 will be described.
The take-out device 8 is constituted by a take-out turret 10, a receiving turret 11, and guides 13 and 14. At the branching section 9, the receiving turret 11 is carried out in the tangential direction of the container carrying PCD (pitch circle diamond-bottle a carrying center). The bottles a traveling center of the conveyor 3 are arranged so that they contact each other, and the take-out turret 10 is set slightly offset from the position where the bottle conveying center of the receiving turret 11 contacts the bottle a traveling center of the carry-out conveyor 3 slightly closer to the filling machine 1. .
This offset amount is in contact with the center of the pocket turret 10 near the center of the takeout turret 10 in contact with the running center of the bottle a of the carry-out conveyor 3, and the bottle a moves toward a portion farther from the center of the takeout turret 10 as it progresses. The receiving turret at the position where the shape of the portion pushing the bottle a reaches the bottle delivery speed, that is, the transport speed of the receiving turret in accordance with the transport pitch of the capper 4 and at the position in contact with the bottle a traveling center of the carry-out conveyor 3 It arrange | positions so that the part which pushes the bottle of 11 pockets may be touched.
