Pick to Light Carts Picking, sorting and packing

Exercises for reading and writing, historical themes presented clearly, learning modules for environmental studies or geography: Noordhoff Uitgevers is the largest education and schoolbook publisher in the Netherlands. Over 400 employees use a great deal of fun, creativity and professionalism to create educational material for Dutch primary and secondary schools. Noordhoff Uitgevers is also involved in vocational training, further education and higher education with books, journals, supplementary digital learning materials and other services. Millions of items pass through the distribution centre in Groningen each year. Since April 2010, nine specially customised order picking carts from Wanzl have been supporting the efficient logistics management of Noordhoff Uitgevers. Within three months of the contract being signed at the end of 2009, Wanzl developed a cart solution tailored to the requirements and wishes of Noordhoff Uitgevers.

In the second step, INTHER Logistics Engineering, which has been a software specialist for the integration of automatic warehouse and order picking systems for the last ten years, equipped the Wanzl order picking carts with the INTHER LC automation software for Pick to Light Carts. "In order to exactly meet the individual requirements in each case, INTHER develops the pick carts for the customer in question," explains Mike Strijbos, INTHER Manager in the Project Department. The number of order picking positions per cart is dependent on the order profile; at Noordhoff Uitgevers it is twelve places per cart. For every one of these twelve order picking positions, a Pick to Light module was installed on the pick cart, which is powered by a battery integrated in the pick cart. Thanks to the static installation of the Pick to Light modules on the pick carts, instead of on the numerous storage spaces in the Noordhoff Uitgevers warehouse, significantly fewer modules were needed and therefore substantial cost savings were made.

A wireless RF module was installed for the connection of the pick carts' INTHER LC software to the Noordhoff Uitgevers Warehouse Management System. This module works according to the latest wireless network technology. The order picking itself saves time, money and legwork: incoming orders are grouped together according to identical item positions using IT. The picker then  receives their order batch and the associated pick cart. The first order picking position is displayed on the central display of the pick cart: the employee goes to this position with the pick cart and confirms the position or the item barcode with an RF scanner. Then the Pick to Light modules on the pick cart light up for the orders that require these items. At the same time, the respective display shows the required order picking quantity. The employee picks the item quantity as shown on the display and presses the switch on the Pick to Light module to confirm. A great advantage of the Pick to Light Cart System is the possibility to complete numerous orders at once (multi order picking). "The integrated INTHER LC software calculates the ideal batch for a Pick to Light cart on the basis of the ABC sorting of items and on order priority. This procedure reduces the walking distance in the warehouse enormously," says INTHER Project Manager Willem Verhalle.

The items picked are immediately distributed across the various orders in the pick cart. A further time saving is achieved during packaging by directly order picking into the cartoned shipping container. This all results in a system that simultaneously picks, sorts and packages.

One-Stop-Shop 
For more than ten years, INTHER Logistics Engineering has specialised in software for the integration of automatic warehousing and order picking systems. Their own developments include a voice recognition system and order picking with Pick to Light and Sort by Light systems, for example. Additionally, INTHER also uses RF scanning and RFID integration. The automation system INTHER LC is used in warehouses, logistics centres and production facilities worldwide. As an executive system integrator, INTHER is therefore the one-stop shop for its customers and therefore on hand for all matters relating to logistical automation. Today, with subsidiaries in the Netherlands, Germany, Moldova and the USA, INTHER operates in many different types of business as a general contractor: logistics, retail/food, fashion, pharmaceuticals, cosmetics, books and magazines, spare parts and multimedia.
