Depalletizer Solutions for Beverage Packaging

Bottle depalletizers are used during primary packaging and initiate the start of bottles traveling down a bottling line. Depalletizers remove empty bottles from layered pallets and place onto an accumulating conveyor and are then transported into the production area. Once they have been transferred onto the conveyor, they are formed into a single file and then continue downstream to other machines in the bottling line. On a beverage line, depalletizers are usually capable of handling bottles, jars, and plastic containers.

Maintaining a consistent speed on the depalletizer machine is crucial to the beverage industry because steady streams of empty bottles helps maximize profits by preventing unnecessary filling and packaging downtime. Using automatic systems for unloading pallets is also a great way for companies to save money on labor costs.

Bottle depalletizers present many opportunities for using automation solutions from Banner Engineering and work together to create an adaptable and highly productive system. Bottle depalletizers can get rather large and include many moving robotics, such as sweep bars, which could easily become dangerous for operators. Installing light curtains could protect operators while monitoring the hazardous areas. Other solutions include barcode readers for verification of pallet contents and sensors for monitoring load level as well as detecting accumulations on the conveyor to maximize efficiency.

Banner’s Type 4 EZ-Screen with a muting is ideal for depalletizer stations with robots because the screens ensure safety standards are maintained while allowing for a free flow of pallets, increasing throughput. The muting allows for a pallet skid to be transferred without shutting down the conveyor or robot cell, helping optimize product flow throughout the distribution center. There is a timing function set at a constant speed that allows for a continuous flow of pallets.

Banner’s RP-LS42F rope pull switches run along the length of a conveyor so the operator can grab and pull it from anywhere to immediately stop the conveyor. Spans of rope range from 6 m to 100 m, providing the flexibility to safeguard long or short conveyors. The RP-LS42 switches are compact and have a variety of accessories available for easy installation and rope tension. They are also made with heavy-impact thermoplastic housing for use in demanding industrial settings.

Safety Light Screens Guard Operators from Sweep Bar
Safety Light Screens Guard Operators from Sweep Bar

The EZ-Screen LPs Type 4 Safety Light screens guard the operators of a depalletizer from the motion of the sweep bar. To guard individuals from the sweep bar, a 14mm resolution between beams prevents access and injury. If an individual or item breaks the beams of the EZ-Screen, the sweeping motion will stop to prevent harm. The low-profile design of the light curtains allows for easy installation along a machine and does not require a PC or additional equipment for setup.

The Q60 background suppression sensor detects when the staging area is clear of bottles or cans and the system is ready for the next layer of containers. The integral timing delay on the Q60 filters out any potentially unstable signal from the bottles as they move in a cluster. Indication is then only made when the area is truly clear and the staging area is ready for more containers.
