The present application relates generally to a container carrier application system, which applies container carriers to groups of multiple containers, and more particularly to container carrier application systems that apply container carriers that extend vertically down outside surfaces of the containers.
Container carriers are used to secure groups of containers so that they may be grasped and carried by a user as a single unit. Specialized machines may be used to apply a container carrier to a group of containers in a manufacturing line. These machines typically utilize rotary wheels to align containers for the application of the container carrier, and the containers in a leading group are in contact with containers in a lagging group. Conventionally, the container carriers are shaped to remain within an area bounded by a footprint of the group of containers, and do not to interfere with adjacent groups. A challenge exists in positioning groups of containers for the application of container carriers that extend vertically down the outside surfaces of the containers, thereby requiring a space between the containers in the leading group and the containers in the lagging group.
To address the above issues, a container carrier application system and a method therefor are provided. According to a first aspect, a container carrier application system may comprise a controller, a conveyor, a container positioning device, and an application device. The conveyor may be configured to, under the command of the controller, convey a plurality of groups of containers from a supply side to an output side, a container of a first group being in contact with at least one container of a second group. The container positioning device may be configured to, under command of the controller, position each group of containers on the conveyor for application of a container carrier to the group of containers. The application device may be configured to, under command of the controller, apply the container carrier to the group of containers. A motion of the container positioning device and a motion of the application device may be synchronized to coordinate a position of the group of containers with a position of the container carrier to be applied to the group of containers. The controller may be configured to control a conveyance speed of the plurality of groups of containers such that a gap is introduced between the first group and the second group of the plurality of groups as they are conveyed along the conveyor toward the application device, the gap being spaced in a conveyance direction of the groups of containers. A potential advantage of this configuration is that a container carrier may be securely applied the first group of containers without interference from the second group of containers.
In this aspect, the controller may be a programmable logic controller, and a first servomechanism and a second servomechanism may be electronically linked to one another and controlled via the programmable logic controller. A potential advantage of this configuration is two components of the applicator system may be cooperatively controlled via the programmable logic controller such that the conveyance of the containers coordinates with the application of the container carrier.
In this aspect, the first servomechanism may be configured to control the container positioning device to refrain from conveying the second group of containers until the first group of containers reaches a predetermined distance from the container positioning device to introduce the gap between the first and second groups of containers. A potential advantage of this configuration is that a container carrier may be securely applied to the first group of containers without interference from the second group of containers.
In this aspect, the second servomechanism may be configured to control the application device to accelerate when seating the container carrier on the first group of containers to introduce the gap between the first and second groups of containers. A potential advantage of this configuration is that a container carrier may be securely applied to the first group of containers without interference from the second group of containers.
In this aspect, the application device may include a roller applicator to secure the container carrier onto top surfaces of the containers, and the roller applicator may be formed in a shape complimentary to a shape of a top surface of the container carrier. A potential advantage of this configuration is that a container carrier may be firmly seated on a group of containers.
In this aspect, the roller applicator may be adjustable in height. A potential advantage of this configuration is that the roller applicator of the system may be used to firmly seat container carriers on containers of different heights.
In this aspect, the application device may include a stomp applicator that applies a downward force to press the container carrier onto top surfaces of the containers. A potential advantage of this configuration is that a container carrier may be firmly seated on a group of containers.
In this aspect, the stomp applicator may be adjustable in height. A potential advantage of this configuration is that the stomp applicator of the system may be used to firmly seat container carriers on containers of different heights.
In this aspect, the container carrier application system may further include a sensor configured to detect when the first group of containers reaches a predetermined distance from the container positioning device. A potential advantage of this configuration is that gaps between groups of containers can be consistently and accurately timed.

The PLC 12A may command a control engine 34 and an operating system 36 via the processor 30. At least one signal (I/O) module 38 may be included for connecting the PLC 12A to other devices, and a serial real-time communication system (SERCOS) interface module 40 may allow a user to control motion of components of the system 10, such as a motion of the container positioning device 16 and a motion of the application device 18 as described below, via a user interface 42 provided on the PLC 12A.

The first servomechanism 44 may be configured to control the container positioning device 16, and the second servomechanism may be configured to control the application device. Motors M1, M2, and M3 may be included in the system 10 to drive the motion of the container positioning device 16, the motion of the application device 18, and a motion of the conveyor 14, respectively. When applying the container carrier 24 to the group G of containers C, the motion of the container positioning device 16 and the motion of the application device 18 may be synchronized to coordinate a position of the group G of containers C with a position of the container carrier 24 to be applied to the group G of containers C. Sensors S1 and S2 may be included in the system 10 to detect the position of the group G of containers C at predetermined locations with regard to the application device 18.
As the containers move along the conveyor 14 toward the application device 18, a container C of a first group G1 may be in contact with at least one container C of a second group G2. By controlling the motion of the container positioning device 16 and/or the motion of the application device 18, the controller 12 may be configured to control a conveyance speed of the plurality of groups G of containers C such that a gap is introduced between the first group G1 and the second group G2 of the plurality of groups G as they are conveyed along the conveyor 14 toward the application device 18, the gap being spaced in a conveyance direction CD of the groups G of containers C.
