ScanMeg BBS ULTRA S

1. ScanMeg BBS+ & ULTRA S Type BBS Single-point, Laser Scanner The BBS series of laser scanners has been one of the most popular units in our product line. There are presently four models using the same technology but designed for different purposes: BBS+4� - used where high resolution is required such as in planer mills, veneer and board plants etc. BBS+48� - identical to the BBS+4 but with a longer range with slightly less precision SE - similar electronics but with a much greater range of up to 14� (4.2m) Ultra S - slightly different electronics with a much greater scan frequency, designed for multiple installations There are many uses for the different modules including: thickness monitoring, trimmer fence checking, cant height at horizontal and vertical resaws, photocell where it is impossible to use a thru beam, low-cost edger optimizer scanner, and the SE has been designed to determine the position of a log on Step-feeders for gap control & board length measurement.Type BBS Single-point, Laser Scanner The BBS series of laser scanners has been one of the most popular units in our product line.

2. BBS+ Scanner Body Each of our single-point lasers are manufactured from a solid aluminium block that is milled out to accept the electronics and PCB board. Due to the special features in the manufacture, there is no need to temperature correct the scanner�s output unlike other manufacturers. The signal remains constant throughout the scanners temperature range. The enclosure is water-tight so there is no problem when welders water down areas where they have been working. Stainless steel screws are used to fasten the back together to form a waterproof enclosure.Scanner Body Each of our single-point lasers are manufactured from a solid aluminium block that is milled out to accept the electronics and PCB board.

3. BBS+ In Differential Mode Differential mode for Quality Control Use BBS+48� at sawmill sorter and BBS+4� in planermill applications Outputs thickness directly in inches in 4-20 mA or serial Differential communication modules for single or multiple scanners in daisy chain (eg. Transverse scanning applications) The BBS4 and BBS48 can be used in differential mode to monitor the thickness or widths of cants and boards as well as the thickness of veneer, plywood and other board products. In some cases both models are used together depending on the situation. This is a very cost effective way to control target sizes such that early warnings can be issued to alert personnel of problems in the manufacturing process. The installation is very simple, with each BBS sensor plugging into a DIFF module that does the differential calculation in the on-board CPU to determine the objects thickness. Special statistical programs residing in the unit can determine average and medium values.The BBS4 and BBS48 can be used in differential mode to monitor the thickness or widths of cants and boards as well as the thickness of veneer, plywood and other board products.

4. Differential Communications Module(3 analog outputs 4-20mA, 2 PNP contacts, RS-485 serial communication, 2 plug-in BabyS or BBS+) The DIFF or differential module allows one to link two BBSs together and the thickness or width measurements are automatically calculated using the on-board CPU. This relieves the PLC from doing all the math calculations. All the setup can be done on this module including Baud rates, calibration, Mode, as well as trouble-shooting. The DIFF module recognizes which BBS model is attached and makes the calculations accordingly. Using this combination is a very economical method to monitor target sizes of boards and cants as well as veneer and plywood sheets. Output from the DIFF module includes analog, RS-485 serial and PNP. Everything that needs to be done for proper operations can be done through the DIFF module. Calibration is a snap. Just put the calibration piece in the field of view of both lasers and push the calibration button. The system auto-calibrates. All the information from each laser is outputted on the digital readout. Error codes help in identifying any problems that may arise.The DIFF or differential module allows one to link two BBSs together and the thickness or width measurements are automatically calculated using the on-board CPU.

Maunganui in New Zealand show their board classifier utilizing the BBS48 in differential for determination of board thickness and the Type SE for the position of the far end of the board. Since the boards come off of a fixed fence, all that is needed is the far end to determine the board�s length. The BBS48 determines the board�s thickness using the 4-20 mA output as well as the boards width, using the PNP output from the BBS in conjunction with the pulse encoder.Automation & Electronics of Mt.

10. Veneer Application Monitor veneer thickness across veneer or composed panels. DIFF Module provides thickness in inches or mm � all calculations done in on-board CPU, not in PLC or PC Daisy-chain modules together 0.001 � 0.005� precision Co-ordinates with TVeneer defect scanner for composing lines This installation at Tolko (ex Riverside) in Armstrong BC is used to determine the thickness of the veneer feeding into the composer. Any part of the veneer sheet that is out of specification is clipped and sent to the chipper. Four pairs are used to measure thickness across the sheet. Also in the picture is the Type TVeneer light-curtain scanner that is designed to detect defects including splits, holes and broken edges. Sheet orientation is also outputted in case the machine has the capabilities to skew the sheet to square it up with the clipper to eliminate extra clipping. The installation was done by the mill personnel with assistance from Iron Code Engineering Co. Ltd. of Salmon Arm, BC.

11. Board Length Application For stud length measurement place BBS48� at each end Provides accurate length measurement through Differential module For longer boards the Type SE has a range of 4� � 14�4� The BBS can be used to measure the length of boards on a transfer deck. Since this is a stud application the BBS48 is used for both the near end as well as the far end. In random length the Type SE would have been used for the far end due to its longer range (14 feet or 4.4m)The BBS can be used to measure the length of boards on a transfer deck.

13. This illustrates the use of the BBS48 and the SE to determine the position of a log on the top step of a Step-feeder and the log�s rough diameter for log sorting. The same setup could be used to control the logs going into a canter line for gap control, utilizing the setback distance from the log line as well as the log�s diameter to set the gap. Automating the system increases the throughput of the line by moderating the flow as well as reducing downtime from poor gap control.This illustrates the use of the BBS48 and the SE to determine the position of a log on the top step of a Step-feeder and the log�s rough diameter for log sorting.

16. Either the BBS48 or the SE can be used to determine the distance from the Log Line to the log that is presently in the top step of the Step-feeder. In this way, better gap control can be effected. With the increases in feed speeds of canter lines, it becomes imperative to get the gap as close as possible right from the start. In this case, another scanner at the far end determines the log�s length as well.

20. The new Ultra S was designed as a single-point laser with a high frequency, 1200 scans/sec. This makes it very useful for monitoring the target sizes of boards travelling in a lineal manner such as a planer. Each pair plugs into the DIFF or Differential Module that automatically calculates the thickness or width and outputs in Serial or Analog to a PC or PLC. All the math is done on-board the CPU so it makes it very easy to set up.The new Ultra S was designed as a single-point laser with a high frequency, 1200 scans/sec.

22. C-Link 10 Concentrator The C-Link receives the inputs from up to 10 Single-point laser scanners per C-Link module. Modules can be daisy-chained together up to 32 C-Links on one circuit. The communication from each sensor to the C-Link is serial. The C-Link assigns an IP address to each connector and therefore all the data from each sensor can be communicated to the controller over TCP/IP Ethernet protocol.C-Link 10 Concentrator The C-Link receives the inputs from up to 10 Single-point laser scanners per C-Link module.
