Jute sacks with coffee: unloaded, palletized, quality assured

Unloading bags from containers is often tedious and strenuous for employees. The bag transport system developed by Copal Handling Systems not only supports automatic unloading and palletizing, but also takes care of quality assurance on the spot.

Copal's bag transport system effortlessly unloads jute bags from containers, but it can do more than just unload. At the same time, the bag transport system detects moisture, takes samples of the contents and palletizes the bags with first-class stacking quality. In addition, bags rejected due to moisture or damage are automatically removed from the system. The system thus solves a well-known, worldwide problem: the heavy physical work involved in unloading and palletizing bags from containers.

Nestlé relies on Copal solution

Nestlé, the world's largest food manufacturer, has decided to use a Copal solution for the automatic unloading and palletizing of jute bags filled with coffee beans. Copal Handling Systems and Nestlé have signed a contract for this. Several of these bag transport systems were put into operation in the second half of 2015. For Nestlé's employees, the use of the bag transport systems makes their work much easier. In addition, the automation of sampling and the rejection of damaged bags will improve the quality assurance program. This collaboration will enable Nestlé to achieve its ambitious sustainability goals. With its mission "Good Food, Good Life", Nestlé wants to create added value for society.

Rotating gripper arm lifts bags weighing up to 100 kilograms

The Copal C2 bag transport system with the Spidergripper unloads jute bags automatically.

With the spider gripper on the conveyor Copal is a specialist in the rapid unloading of containers and fast palletizing. The question is always how to relieve the strain on personnel. One focus of the product range is on unloading bags. The Spidergripper was developed for this purpose, with which sisal sacks, polypropylene and polyethylene sacks as well as jute sacks filled with cocoa, coffee, nuts or tea, for example, can be safely unloaded. The jute sacks are removed from a container fully automatically and placed on an extendable conveyor belt. The gripper can rotate 90 degrees, lift sacks weighing up to 100 kilograms and has several points of rotation and inclination. This means that it can also pick up bags or bales that are not lying flat but at an angle and place them on the conveyor belt of the Copal C2. Sensors also ensure that the gripper is positioned automatically. All the functions of this innovative gripper have been added to the operating system of the Copal C2 container unloader.

Unloading without physical effort

The bag transport system is operated by just one employee, thereby ensuring process optimization, reducing operating costs and increasing productivity. The system allows containers to be unloaded without physical effort. The system can be integrated into any warehouse management system. Mixed container loads and other non-cardboard products can also be processed on the Copal systems. All Copal systems are patented, CE-certified and TÜV-tested.

Mobile solution for unloading and palletizing

Copal also has a solution for unloading containers in places where no ramp is available or which have to be unloaded outdoors: the mobile unloading and palletizing trailer. In a special trailer, a Copal C2 container unloader with a robot can unload and palletize the goods directly. The Copal mobile unloading and palletizing solution is ready for use within 15 minutes and can be deployed at any location.

The solution is suitable for 20-, 40- and 45-foot and high-cube containers. Palletizing is possible on port pallets, industrial pallets and Euro pallets. The system can be implemented with a normal tugger train unit. The transport width is 295 centimeters. The system is clicked onto the chassis with spring pins and is therefore considered a load. A simple approval procedure is therefore used, which does not require any supervision.

Fresh air included

Overpressure is generated in the closed cabin for the machine operator, which ensures a healthy working environment for the employee. The compressed air system also blows one cubic meter of fresh air into the container per operation. This removes the residual gases remaining after degassing.
