Fanuc Robotic Part: AccuChop Technology

What is AccuChop?

The Accu­Chop pack­age main­tains effec­tive and effi­cient coat­ing for gel­coat (resin and cat­a­lyst) and chopped fiber­glass (resin, cat­a­lyst, and glass) applications. 

What does Accu­Chop provide?

Accu­Chop’s closed loop process con­trol sys­tem cre­ates a high­er qual­i­ty and more con­sis­tent end prod­uct by tak­ing advan­tages of the fol­low­ing features:

• Resin and glass deliv­ery rate con­trol and dis­play features
• Dif­fer­ent detec­tion alarms to help mon­i­tor and recov­er events such as dam­aged deliv­ery lines or bro­ken glass supply
• An effec­tive way to han­dle error recov­ery events
• Mate­r­i­al usage and sys­tem monitoring 
• Inde­pen­dent trig­ger­ing for resin and glass chop­per motor
• Auto­mat­ic and con­tin­u­al cal­i­bra­tion through a fast response adap­tive con­trol scheme
• Auto­mat­i­cal­ly deter­mines equip­ment char­ac­ter­is­tics dur­ing calibration
• Eval­u­ates true part costs and yields
• Quick feed­back on amount of mate­r­i­al being applied to the part
• Accu­rate tar­get weight
• Dis­play of pro­duc­tion infor­ma­tion and cycle times 

What oth­er advan­tages will Accu­Chop provide?

A com­plete reduc­tion in oper­at­ing expens­es as the resin usage can be decreased with the tight flow rate con­trol. The waste dis­pos­al costs will also be less as the end prod­uct will not have to be reworked near­ly as often with the Accu­Chop qual­i­ty provided. 

How does Accu­Chop work the Resin/​Gelcoat Control? 

The Accu­Chop resin con­trol loop pro­vides a pneu­mat­ic sig­nal from the I/P trans­duc­er to the pump air motor. A mass flow meter then mea­sures the resin flow and sends a sig­nal to the robot con­troller. Cal­cu­la­tions of the flow rate are com­plet­ed which then sends cor­rec­tive closed loop con­trol sig­nals to the I/​p trans­duc­er in order to make the cor­rec­tions to the air pres­sure pro­vid­ed by the resin pump. The soft­ware is able to achieve set point flow for the future very quick­ly as the closed loop con­trol ​“remem­bers” the com­mand val­ues required.

How does Accu­Chop work the glass control? 

The Accu­Chop glass con­trol loop pro­vides a pneu­mat­ic sig­nal from the I/P trans­duc­er to the air chop­per motor. The RPM of the chop­per motor mea­sures the glass usage and sends a sig­nal to the con­troller. Cal­cu­la­tions for glass usage are cre­at­ed and cor­rec­tive closed loop con­trol sig­nals are sent to the I/P trans­duc­er. This helps to make cor­rec­tions to the air pres­sure pro­vid­ed to the chop­per motor. As seen with the resin/​gelcoat, the Accu­Chop con­trol fea­tures ​“remem­ber” the nec­es­sary com­mand val­ues and enable the soft­ware to achieve set point flow in the short­est pos­si­ble time.

How does Accu­Chop Detect Glass Breakage?

Sen­sors are set up and used to mon­i­tor the glass as it is rout­ed through. When­ev­er glass break­age is sensed, an alarm goes off which stops the robot. This allows the user to re-feed the glass strands and con­tin­ue as normal

What is required for Accu­Chop to prop­er­ly run?

• Ensure the robot con­troller sup­ports the system
• High speed counter modules
• Fanuc 32-bit input module
• Transducer/​Regulators
• Feed­back Device
• Accu­Chop Soft­part inte­grat­ed into Paint­Tool Application
