wwt is also a reliable partner in the food industry, encompassing the development, construction and implementation of complete systems, individual components and spare parts for special machine building. In order to make them “taste” and serve truly delicious, we thoroughly analyse specific problems and requirements. Next, we discuss them with our customers in order to optimise individual components or develop the most suitable complete solution.
Over 15 years of experience as well as outstanding knowledge of the industry and industrial processes enable us to develop individual automation solutions. We provide special mechanical engineering, always accurately reflecting the requirements of our international customers.
Our extensive experience as well as outstanding knowledge of the industry and industrial processes make us capable to guarantee the development of an optimal automation solution.
Our solutions for conveyors, transport lines, machines and components are applied all over the world. Thanks to them, production processes become more efficient, faster and safer. We know what matters in your industry. Therefore, we want to thoroughly understand the specific requirements of each process in order to deliver the best solution.
wwt is headquartered in Essen but our special machines and individual industry solutions are located all over the world. Assemblies are currently taking place in twelve international locations and, naturally, in Germany.
We offer modular and individually tailored solutions for automated food packaging and confectioning (i.e. labeling, marking, collective packaging, and others). Our unique concept of handling food and related packaging covers the entire process: from individual production, up to fully automated end product preparation, e.g. in the form of so-called stairs.
For example, 150 trays per hour
For example, 7,000 bags per hour
Some packaging, due to its shape, require special handling during selection and transport for further processing. The core of the procedure of unloading the standing bags (or similar products) are tray loading and unloading robots. They dynamically respond to the Conveyor Tracking and situation-driven switching to upcoming downstream devices in the system.
Robot grippers equipped with suction cups simultaneously lift several bags on a two-lane belt conveyor. This type of construction excludes the occurrence of failure on the belt – both robots supply both tracks independently of each other, alternately with the product. In the event of an error of one belt, both robots automatically load the running belt conveyor. A stacking robot equipped with a gripping fork rotates the unloaded trays at the end of the belt and empties the unprocessed bags. Optionally, the outfeed part of the system can be supplemented with a fully automatic product feeder and a packaging system with a palletising function (optional for discussion).
For example, 1,800 bags per hour
For example, 1,800 bags per hour
wwt combines what belongs together. Our universal labeling station for wrapping and confectioning of Flowpack bags takes over all the important operations that are required to label the products packed in bags and link them with secondary products. Flowpack bags are loaded on a conveyor belt either manually or fully automatically. Next, they are brought into the correct position to be included in the cycle.
After smoothing the bag, a LinMot biaxial handling linear motor takes the label from the dispenser using a vacuum gripper and transports it to the next station where the label and the secondary product are combined. High-precision mechanics separates the pre-perforated string of bags without damage and joins the secondary product with the label. In the third step, the Flowpack bag is labelled in a predetermined place on the packaging.
For example, 250,000 candies per hour
For example, 300 boxes per hour
Complex production processes require a particularly intelligent and integral concept. wwt offers a complete food storage system that smoothly integrates into the production process and takes over everything from feeding the product up to loading it onto pallets – all this in one device.
Before further processing, the finished product is checked by a metal detector and defective goods are automatically rejected. Approved food is transported on special belts that meet food contact standards. A batch of products subject to processing is located below the conveyor belt. An automatic system controls the motion synchronisation while the robot lines up, organises and sets the batch of product correctly on the upper belt. The product reaches the edge of the belt exactly at the predetermined point. The delivery of cargo in E1 containers is ensured by intelligent pallet management and a standardised system. In case of multi-layer storage, separation layers are automatically cut and inserted into the containers by a robot. Finished boxes are stacked back on the pallets in the system. An integrated pallet buffering system is used to deliver empty pallets.
For example, 10,000 pieces per hour
For example, 900 trays per hour
Promotional goods and delicatessen products, as well as cheese and cottage cheese products reach the supermarket’s assortment most often arranged in a form of the so-called stairs. wwt offers an intelligent, complete system for confectioning of the food packaging that covers the entire process – from product supply to collective packaging. The client precisely determines which products, in what quantity and order are selected to the stairs.
Product variants that are transported with the lid down or vice versa during production are adapted to the loading well in advance. An intelligent system arranges the products according to the requirements previously provided by the customer. Then the stairs are automatically loaded. Flexibility of the load is increased by an additional rotating buffer. The infeed of products to the packaging operation can be carried out via pallet spaces or a direct connection to a buffer warehouse. In both cases, the operation is fully automated, that is, runs unmanned. Connection to the MES system for OEE determining and for product tracking is integrated into the control system. The method of packing and confectioning shipping pallets is also selected at the control level. Full or top wrap only, bottom label or no wrap – the customer specifies it all.
