Shuttle Feed Positioner

Industrial Automation - Material Positioning

Shuttle Feed Controller

Whether you are doing short or large production runs, Shuttle Feed Controllers are available for punching, drilling, or cutting operations.

For example, the Saw Controller, operator's console shown above, will automatically measure and feed material to be cut to various lengths under program control, using automatic or manual saw cut operation. The operator can also quickly specify single cuts or multiple cuts.

Result? No time lost in checking and rechecking measurements. Accuracy of every punch, cut, or drilling operation is assured. Stop wasting material. Bottom line? Higher productivity. Time and money saved every day.

This is a true CNC controller and can be programmed and operated using traditional industry standard ISO code (G & M codes) or by using a “Cut List” programming feature. Up to 10 line entries are permitted in a Cut List Table and 50 Cut List Tables can be stored in the controller. Each line entry in the Cut List Table consists of Quantity, Length of Part, and Speed of Saw Blade. Initialization of the Cut List Table permits the entry of the length of raw material being used. An “I/O” input for an optional “end of material” sensor, is also provided.

Description and Features

	Operator console is machined out of solid aluminum and features a durable, user friendly membrane keypad.
	Controller is programmed either by using the industrial standard ISO code (G & M codes), or by using the Cut List programming feature.
	Controller uses standard 120 VAC single phase current.
	Controller functions in English (inches) or metric (mm) units.
	Left or right hand configuration parameter allows the unit to be installed to the right or left of the work station (saw).
	The console provides full program Editing functions. Dry Run and Optional Stop features are provided as well as program Single Step mode.
	There are four displays: Two large 4 digit 7-segment displays, one large 8 digit 7-segment display, and one 4x20 character backlit LCD display.
	Coolant pump, chip auger, fixed vise, shuttle vise, and saw down feed are all controllable from dedicated console keys as well as by the programs.
	Four different Counters are maintained. These Counters can be reset from the console, or from the programs. - The Part counter is continuously displayed on the console for the operator. - The Total Cut counter (to determine saw blade wear), the List counter (number of times the Cut List has been run), and the Program Cycle counter (number of times G & M code programs have been run) are accessible and maintained by the factory or shop supervisor.
	Counter functions are accessible in manual increment/decrement mode as well as from all program modes.
	An emergency stop (E Stop) switch is provided on the console as well as an input port for additional E Stops.
	There are two analog "I/O" output ports to control motors. There is a –10VDC to +10VDC standard industry interface used to control the servo motor for the linear axis. The second port is an industry standard interface 0 to +10VDC port used to control an optional AC motor inverter drive (saw arbor).
	There are 3 communication ports: One RS-232 and two RS-485 ports.
	Output I/O: There are 14 relay contact outputs. (11 assigned, 3 free, 10 under M code control)
	Input I/O: There are 22 opto-isolated inputs (13 assigned, 9 free, 14 under M code control)
	Industry standard Quadrature encoder ports: One is provided as standard and three are optionally available).
	Write and download programs from any PC to the controller’s PC port (RS-232). The IBM-compatible PC host download program is supplied with the unit.
	Program memory is stored in EEPROM circuits. Optionally, additional EEPROM circuits can be added for additional program storage space. Standard capacity is configurable, such as 55 programs of 25 lines or 11 progams of 125 lines, etc. This capacity can be increased.
	The supervisor mode, protected by a physical key lock, is used for modifying traverse speeds and acceleration parameters.
	Parameter settings are provided for specifying system values such as zero position, width of the kerf cut, offsets, and left or right operation related to the work station (saw).

	Parameters for kerf cuts and offsets are automatically calculated in the distance the material is to be moved.
	Several other parameters are provided at installation time, such as Backlash, if required, and are automatically calculated when material is moved.
	There is an Emergency Stop (E Stop) switch on the console as well as an "I/O" input port to permit installation of additional E Stop switches.
	An optional sensor may be used to monitor the speed of rotation of the saw blade, allowing for the "closed loop" operation of an inverter driven saw blade motor.
	Security input can be used to interrupt saw operation when a saw cover is opened.

Remote synchronization of the saw controller can be implemented with another controller through 3 I/O ports for Remote Start, Remote Stop, and Operation Complete.
