CONSTANT TENSION COILER WITH ELECTROMAGNETIC BRAKES

Abstract

An apparatus, system, and method for a new and improved constant tension application spooler and or coiler system that provides PID loop controls for an electromagnetic braking system to regulate torque and tension while the material is coiled and or wound onto and or off a reel so that the tension is maintained at a desired amount during the winding and or unwinding process.

Claims

1. A constant tension application spooler and coiler system that provides constant desired tension on elongated material into the coil and reel during the winding process and unwinding process comprising: a frame; a spindle rotationally fixed to said frame; a feed system for moving said elongated material into and out of said spindle; proportional-integral-derivative controlled electromagnetic brake system attached to said spindle that provides constant desired tension on said elongated material during the winding process and unwinding; and a computer control in communication with said spindle and said proportional-integral-derivative controlled electromagnetic brake system.

[0022] FIG. 2 is a general perspective view of a preferred embodiment in accordance with current invention.

DETAILED DESCRIPTION OF INVENTION

[0023] Referring to the illustrations, drawings, and pictures, and to FIG. 1 in particular, reference character 10 generally designates a new and improved spooling and or coiling apparatus, system, and method of using the same constructed in accordance with the present invention. Invention 10 is generally used with elongated material(s) 15 (not depicted) needing to be made into smaller segments for distribution from a larger spool and or reel. Elongated material(s) 15 may be but is not limited to plastic profiles, such as but not limited to hollow profiles, flexible extrusions, hoses electrical cables, steel cables, wire cables, felt, and so forth. For purposes of convenience, the reference numeral 10 may generally be utilized for the indication of the invention, portion of the invention, preferred embodiments of the invention and so on. It is also to be understood that invention 10 should not be considered limited to just a spooling and coiling and the terms should not be considered to limit the invention to such.

[0024] Invention 10 may comprise a frame 20, a spindle(s) 30, a feed system 40, a computer control 50, and a power source 60. It is understood that spindle 30 may be utilized with a spool and or reel 70 (not depicted) although it is understood that spindle 30 may be utilized without a reel 70 when coiling elongated materials.

[0025] The invention contemplates a proportional-integral-derivative system 80 (also referred to as PID) controlled electromagnetic brake system 90 (also referred to as EMB) wherein tension on the electromagnetic brake system 90 goes up/down with respect to outer diameter (also referred to as OD) of reel 70, torque on spindles 30 go up/down with respect to OD of the reel 70, a pneumatic roller clamp forces material against roller controlled by the electromagnetic brake system 90, adjusting tension/torque allows the spindle(s) 30 to maintain a constant speed to match extruder 100 (not depicted).

[0026] It is understood a proportional-integral-derivative controller (PID controller or three-term controller) is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control. The basic idea behind a PID controller is to read a sensor, then compute the desired actuator output by calculating proportional, integral, and derivative responses and summing those three components to compute the output. It is also understood that electromagnetic brakes (also called electro-mechanical brakes or EM brakes) slow or stop motion using electromagnetic force to apply mechanical resistance (friction).

[0027] It is therefore contemplated that invention 10 may be a constant tension application spooler and coiler system that provides constant desired tension on elongated material into the coil and reel during the winding process and unwinding process comprising: a frame; a spindle rotationally fixed to said frame; a feed system for moving said elongated material into and out of said spindle; proportional-integral-derivative controlled electromagnetic brake system attached to said spindle that provides constant desired tension on said elongated material during the winding process and unwinding; and a computer control in communication with said spindle and said proportional-integral-derivative controlled electromagnetic brake system.

[0028] Changes may be made in the combinations, operations, and arrangements of the various parts and elements described herein without departing from the spirit and scope of the invention. Furthermore, names, titles, headings, and general division of the aforementioned are provided for convenience and therefore, should not be considered limiting.
