RFID: The future for order pickers and trilateral
May 10, 2010
The control of the order pickers and trilateral in the corridors and areas of the store is a decisive factor to ensure safe operation and compliance with all the functions required by law, such as the protection of end of corridorthe disconnection of the functions of lifting or reduction of the speed. Traditional systems are predominantly used magnets installed on the ground to carry out this control. However, with these switches only mechanical, it is possible to pass on a very limited amount of information to the stacker. Often that no longer enough for the increasingly complex installations and the increasing security requirements of today.
To control the new machines of Jungheinrich not installed magnets on the floor of the store, but RFID transponders. The vehicle itself is equipped with a device for reading and writing RFID that communicates with the transponders. These perform two functions: on the one hand, to identify the corridors and areas of the store, on the other hand, recorded and permanently notified the tour of the stacker. This makes it possible to determine the exact location within the store at all times. What is more: control of the vehicle has commands all the topology of the store. Therefore, it is possible to trigger activation/deactivation and functions of safety in any place, for example, the reduction of the speed through corridors of evacuation or disconnection of the functions of elevation in corridors of limited height.
Optimization of performance depending on the topology of the soil
Not only RFID ground control offers advantages from the point of view of security, but it also allows us to optimize profiles depending on the topology of the ground walking speed. In practice, the maximum speed of movement of a vehicle is usually determined by the flatness of the land. In many cases, the quality of the soil it is not uniform, and until now was not forced to reduce the speed of progress in general because of a few bad stretches. Now, with the new system, it is possible to optimize profiles speed according to each specific situation and move more slowly only when really required by the soil. As a result, the performance in the firm of pallets has been able to raise up to 5% in each case despite the considerable differences in the conditions of the soil.
Automatic displacement: "Has reached its destination"
The 'Navigation by warehouse RFID' module for the automatic posting of the order pickers and trilateral of narrow corridors to the position of destination already had been included in various projects of warehouse. The basic function is the determination of the exact location for RFID. In addition, control of the vehicle is integrated into the system of management of the warehouse (SGA). Transport and order picking orders are transmitted directly from the computer of the warehouse to the vehicle through the system radio frequency. Displacement correction and erroneous are excluded in this way. Control elements that make up this system include the horizontal positioning, a pre-selection of the height of elevation and to the trilateral stacking automatic cycle.
"The system of management of the warehouse information is transferred directly to the driver of the truck", explains Tobias Thiele. The advantages for the user are a high quality of stacking and picking and a considerable saving of time. "The vehicle is automatically directed to the desired position of the shelf by the shortest route, at the optimum speed and with the lowest possible energy consumption as the user enables the corresponding function," continues Thiele. The first practical tests have resulted an increase in performance in the clearance of goods and picking up to 25% approximately.
In addition, relieved the workload of the driver, which can relax completely and to be guided to the appropriate destination. Similar to the principle 'pick by light', when you reach the correct position turns on a driver to the corresponding point of the vehicle. This pilot indicates to the driver if you must collect the goods right shaft or the left cavity of the shelf.
Intelligent control of performance
The productivity of the machines of Jungheinrich has increased rapidly in recent years thanks to the use of the technology of three-phase current. Vehicles of the future not only must deliver high performance, but it must also be equipped with intelligent technologies in order to attach to the IT system and integrated into the logistic processes in an optimal way. The application of RFID technology for soil control and browsing through the store is an excellent starting point for this.
Jungheinrich is one of the leading companies at the international level in the field of trucks and storage and material flow technologies. The company, as a provider of logistics services of own production, offers its customers a wide range of products: stackers, shelves, services and advice for the entire internal logistics systems.
Jungheinrich, specialist for more than 30 years provide logistical solutions to its clients, presents its new logistics consulting service based on that, since Jungheinrich, qualify as r & d in the logistics consulting in the Village of SIL 2010 exhibition, with analysis of flows of materials and simulators of latest generation design tools.
In the words of its director of logistics systems, Asier Barredo, "we will present in the SIL a new way for customers to understand much more participatory, logistics consulting".
Jungheinrich offers well in the village of SIL exhibition a free initial study of the needs of stakeholders that pass through the booth.
Through its design and calculation tools, visitors may provide at the time of an initial analysis on the current situation and the different alternatives to value to improve the internal logistic flow.
At the same time, through a simple set of questions, customers will know the actual needs of automation of their facilities and the type of optimal Automation to do so.
"Ultimately, we want that logistics experts, can have very intuitive tools with clear and reliable results that help them to make decisions for themselves about future changes that should be undertaken in your store, advised course at all times by Jungheinrich consultants", says Asier Barredo.
The new logistics consulting of Jungheinrich provides popularize to maximize the use of material flow calculation tools and demystify the complexity in the decision-making process.
According to Asier Barredo, "if we have sufficient operating data (number of lines per day, ABC classification, number of references, etc.) the final solution on the different possible scenarios may be taken by the customer on the basis of more strategic approaches."
Jungheinrich has different audiovisual media to show to visitors of the SIL development live of different projects that are exposed by the interested parties.
