Identification products in Logistics industry 1 – Barcodes

Our recent newsletters has to a large part been focused on products and their implementations in the process industry, but they are also well suited for the logistics and warehousing industry. In the coming month, we will present a series of newsletters were we introduce our products in this sector, and how they can be implemented. 

We will start in this mail by our EVS138/144 series of barcode readers, and in the next mail we will discuss RFID reader, followed by accessory equipment and implementation services.

Our range of EVS138/144 barcode scanners are ideal for the transportation and logistics sector. Being rugged and robust with a wide reading area, they are suited for both stationary placements as well as mobile on for example a forklift. Our range cover models well suited for outdoor use in strong sunlight where many ordinary readers might have trouble reading the codes, we have also models equipped with LED spotlights for indoor readings in dark warehouses.

For larger reading ares on a wide forklift mount, two units can be Master/Slave coupled and together work as one wide angle reader, or with each reader working separately to fail proof the reading. For stationary use our readers could be placed by a conveyor belt, reading the codes as they pass by. With a wide reading range, our readers easily pics up codes as they pass by.

For special conditions with hight demands on barcodes robustness, our readers can handle barcodes cut out in metal sheets.

A typical use for our code readers would be for container- or pallet handling and identification, the interface is a standard RS-232 and integrate with most Warehouse management systems.

We can also help customers to a complete system covering handheld barcode reader solutions for portable use through our network of suppliers.

Replacing OIS-L 76/77 in Cimat AGV system

One of our most recent request from a customer was to help them update their old Baumer OIS-L readers whish was beginning to show their age. The update was complicated by the fact that the Tag Data needed to be translated by a resolver database in real-time to positional data for the Cimat AVG:s that were and integrated part of their system. Part of this was also the need to send a tag-in-field signal to their PLC when a tag was in the antenna field for reading.
We solved this by adapting our previous Protocol Converter, make it modular and develop modules where a resolver database, as well as tag-in-field functionality, could be added.

The MPC is a further development and merge of our ZIOX host unit and Protocol converter. Following customers needs, it evolved and “MPC” now stands for Modular Protocol Converter – making it possible to add desired functions to the base unit, and thereby simplify the development of customer-specific requests. There are for example a complete keyboard emulator as well as a Tag-In-Field circuit that will send a signal as soon as a tag is within reading distance of an RFID antenna.

The basic MPC still keep the basic functions:

  • Bit rate converter that also converts stop/start bits and parity.
  • ZIOX-host controller.

Which can be extended with for example

  • Logic controller – database with resolver data.
  • Keyboard emulation
  • Customer-specific modules
  • Tag-In-Field circuit that will send a signal as soon as a tag is within reading distance of an RFID antenna

Barcode and RFID working in harmony

In some cases, RFID is the most efficient solution to a specific issue, at some times it is barcodes. At other times you might have to use both technologies to make the best outcome for the customer.

Ident System has in a couple of cases successfully combined the technologies in warehouse/logistics settings where the forklift has been equipped with both our EVS138 in a master-slave configuration to increase the reading area and an IDeal125, with an antenna mounted under the forklift to read tags embedded in the concrete floor.

When the WMS process is started, the forklift approaches the pallet to be moved and the RVS138 automatically start scanning for the code and read it- Thanks to the Master-Slave configuration of two EVS138, a large area can be scanned at a distance up to 13 meters. When the code is read the driver will get instructions where the pallet should be delivered on his terminal. This truck-mounted terminal will be communicating with both EVS138 and IDeal125 through an RS232 interface.

When the truck reaches the drop-off location, for example, a container to be loaded, the antenna mounted at the underside of the forklift reads a tag embedded in the concrete floor and either confirm that the correct destination has been reached, or raise a warning that the wrong tag has been read.

This whole WMS process is set so that it is totally automatic, with only input from the driver being when the process is started, right before the pallet is picked up. Closure of the process is done automatically only when the pallet has been dropped off at the correct destination, if the tag at the location is wrong,m the process will not close.

Introducing our Smart Protocol Converter

Early this year we introduced our EVS Signal Interface Converter (EVS-SIC) as our next product in a series of new releases where refocus on increasing the life and compatibility of your existing system. We have now merged this unit with all the functions form our ZIOX-Host Controller and included more useful features and changed its the ma to EVS-SPC.

  • Keyboard emulator
  • Serial Data Conversion
  • Logic controller
  • ZIOX Host Controller

By connecting the USB port to your forklifts, our EVS-SPC can act as a keyboard emulator instead of Protocol Converter. This means that a readers output when connected to the input of EVS-SPC can be transferred to a truck terminal as if typed on a keyboard. As for the serial data conversion, the connection is made through standard RS232 interfaces both in and out, and the transfer rate on both ports can be selected between 1.200 to 115.200 kbit/s. Parity and/or Stop bits can also be converted. The EVS-SPC can also be used for logic control, i.e. the unit can be programmed with a database for verification of approved ID numbers, which are either used for verification that the tag is correctly read or for control purposes of a connected unit. Lastly, we have integrated the functions of our ZIOX Host converter conveniently into the EVS-SPC to facilitate communication between main systems set up for communication with older devices protocol, in our case often the Baumer Ident ZIOX16 system. EVS-SPC can both act as a polling device for the new system and also converting the host protocol and message to ZIOX16, which means that customers can connect the new IDEAL134,2 system more or less directly in an existing environment. Finally, the EVS-SPC has a software-controlled 5V/1A voltage output that can be externally accessed on the serial port pin 9.

Dynamic pallet volume measurement – Cargospect

Identsystem AB are now adding the Cargospect volume measurement system from CIND to our product portfolio. 

Cargospect is an optical system for precise measurement of the volume of a pallets load – for example when a loaded forklift passes the system and is ideal to use for optimising vehicle loading and for invoicing according to shipping volume. Cargospect work fast and with high accuracy.

Cargospect can be combined with barcode and RFID-readers like our own EVS138 and IDeal series for seamless integration and identification of the goods being measured.

The dimensions of the new and old units will be different, so for existing customers who want to replace units, or add more to their operations we are offering reduced prices on the old units until the end of the year.For more information and orders, please contact us at contact@identsystem.com, or through your ordinary contact within our company. 
Please note that the picture above shows the Pan/Tilt unit with the imager camera mounted. The camera is not part of the offer.

More features in our Signal Interface Converter

A couple of weeks ago we introduced our EVS Signal Interface Converter (EVS-SIC) as our next product in a series of new releases where refocus on increasing the life and compatibility of your existing system.

That release was focusing on presenting the Serial Interface Conversion aspect of the Converter, but it has a second function.

By connecting the USB port to your trucks (or other devices) USB port, our EVS-SIC can act as a keyboard emulator instead of Signal Converter. This mean that a readers (RFID, Barcode) output when connected to the input of EVS-SIC can be transferred to a truck terminal as if typed on a keyboard.

As for the serial data conversion, the connection is made through standard RS232 interfaces both in and out, and the transfer rate on both ports can be selected between 1.200 to 115.200 kbit/s. Parity and/or Stop bits can also be converted.

The EVS-SIC can also be used for logic control, i.e. the unit can be programmed with a databse for verification of approved ID numbers, which are either used for verification that the tag is correctly read, or for control purposes of a connected unit.

Note that EVS-SIC can only be used as Signal Converter or keyboard emulator, not both simultaneously. 

EVS138 Master/Slave configuration

If you have need to cover a large area to find the location of your code, or if your goods vary in size to a significant degree we suggest that you use 2 EVS138 in a Master/Slave configuration.

With EVS138 cameras in Master/Slave configuration you can search and scan the code over a large area and when any of the cameras find the code, the data will be sent through the common RS232 interface.

The Master/Slave connected cameras can also be used for read verification which results in a “good read” or “no read” signal on the digital I/O.

EVS138 is able to read codes at a distance up to 13 meters, depending on the code size and density.

EVS144 series code scanners

Identsystem AB EVS144 Series are code scanners developed especially for forklift mounting. The EVS144 scanners are available in 2 versions with different read heads depending on requirements and application. Both scanners are operated by the forklift driver by means of a joystick, which in turn, works a read head mounted on a movable unit. The driver then controls the camera that reads the codes accordingly. The System is easy to install because of the small dimensions.

EVS144 imager reads barcodes and 2-dimensional codes (2D) it has a reading distance between 0,2 m up to more than 13 m.

Imager series is based on the latest matrix technology and is designed to handle a tough industrial environment. Readers are equipped with auto-focus system and have built-in error correction.

EVS144 line scanner read code at distances of 3-6 meters, depending on the size of the barcode. The scanner is operated by the forklift driver by means of a joystick, which in turn, works a read head mounted on a movable unit. The driver then controls the camera that reads the codes accordingly. The EVS144 line reader is equipped with a specially developed LED. The Line scanner is a CCD line based reader which works extremely good at reading poorly printed codes directly on the surface and also works in outdoor conditions. It can also read inverted codes.

Both these readers can be set up with a very easy-to-use setup software. The readers can be configured to open and close processes in SAP to really make your inventory system work with as little man-made input as possible.
