随着Motion Tech Automation的工程帮助(www.motiontech.com) and servo technology from the electric drives and controls group of Bosch Rexroth (www.boschrexroth.com), Thiele built a machine that can erect up to 2,200 containers/min, in sizes from 6.5 to 16 oz., in a variety of heights and configurations. Containers can be cans or bottles. From 4-packs to 30-packs to the two-by-six configuration of the increasingly popular refrigerator pack, the ServoBeverage Packer stands ready. It relies on 10 independent Rexroth MKD servo motors with absolute feedback, each controlled by a Rexroth DKC servo drive. Also a key component is the master PPC motion controller. Running Visual Motion software, this SERCOS-based controller synchronizes all of the machine’s operations. It also has a DeviceNet interface and an integral programmable limit switch (PLS). The 10 servo axes on the machine are rotary placer, six infeed starwheels, carton flights, barrel cam loader, and overhead confiner.
Compact DKC伺服驱动器电子设备允许使用标准300毫米橱柜进行紧凑的机器设计。伺服驱动系统的另一个元件,MKD伺服电机是IP65额定的,它为机器冲洗功能提供。电机提供高达187nm的峰值扭矩,并且它们的免维护操作归因于无刷设计,并具有终身润滑的轴承。
Stephen Kaye,Thiele Cartoning和Case Packing Product Product Manager表示,由于其伺服控制的包装模式改变,这款盒装是特殊的。“此前,这种机械变化需要一个小时,现在需要不到十分钟,”他指出了。他补充说,伺服控制的星轮进给,提供温和的容器处理,以便最小化刮擦和凹陷。
Kaye notes that the ServoBeverage Packer uses a proprietary method of opening and erecting square cartons with great efficiency. Also, its servo-driven rotary carton setup is electronically timed to match the carton flight system. This minimizes debugging time during the startup process and also greatly simplifies the fine-tuning required to accommodate material variations on the customer’s production floor.
Kaye说,也显着的是Pack模式转换。六个伺服驱动的星形轮料件负责形成包装模式,并且在改变容器配置时,它是以电子方式的而不是机械完成的。
“If a customer wants to run a two-by-six 12-pack configuration and then change to a three-by-four 12-pack configuration, for example, the operator simply selects the pack pattern change on the HMI touchscreen, which alters the servo parameters to achieve the new pack pattern,” says Kaye.
Two additional machine features, he adds, are noteworthy. One is the overhead guide system. The refrigerator pack is only two cans wide, and the pattern could separate when containers are being pushed into the carton. So incorporated into the machine is a servo-driven overhead guide system, which eliminates the possibility of pack separation during the carton-loading process.
The final machine feature of significance is the special glue pattern required for the can dispensing feature built into the carton. The specific glue patterns are controlled through the Rexroth servo drive so that the glue pattern automatically changes, depending on the selected pack pattern. The servo drive also automatically adjusts the glue pattern timing, depending on machine speed.
ServoBeverage Packer最近在墨西哥领先的啤酒厂和Corona和Modelo BEERES的生产商开始生产Modelo。Modelo将运行12个计数冰箱包以及18次纸箱。
