Abstract
Abstract A system and method are disclosed for automatically stamping designs onto candles under computer control. For a given stamped mark, a turret selects the tool with a specific die is to be stamped. The turret orients the tool angle about the axis defined by the tool's travel line during stamping by use of a planetary gear system. A rotatable chuck mounted on a movable bed selects the location on the candle surface to receive the die. A linear solenoid plunges the selected and oriented tool onto the candle. This process is repeated until all marks in a desired design are completed. The planetary gear system is designed so that all tool orientations are controlled by one motor, and tool anti-rotation during travel is controlled by the face length of a sun gear.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
254 words
A computer controlled apparatus for stamping a design into a work piece's surface comprising: (a) stepper motor driven turret means for: (i) selecting a working tool having a die and a vertical axis from a plurality of tools, said working tool being placed in an operating position and having a line of travel normal to the work piece surface; (ii) orienting the working tool die about said vertical axis; (iii) maintaining the orientation of the working tool die during stamping travel; and (iv) controlling the orientation of the other tools in the turret; wherein the orientation of the working tool and the other tools are controlled with one stepper motor; (b) movable support means for holding the work piece which is capable of positioning the work piece in relation to the operating position of the working tool; whereby a selected position on the surface of the work piece is positioned along the line of travel of the working tool; (c) plunger means for striking said working tool into the work piece thereby stamping the die of the working tool into the surface of the work piece; (d) computer means for: (i) selecting the working tool; (ii) orienting the die of the working tool; (iii) positioning the work piece in relation to the working tool; and (iv) controlling and actuating the plunger means to stamp the die onto the work piece; and (e) computer means for controlling and repeating steps (a) to (d) until the design is stamped into the surface of the work piece.
Claim 2
Dependent Claim
254 words
A computer controlled apparatus for stamping a design into a work piece's surface comprising: (a) stepper motor driven turret means for: (i) selecting a working tool having a die and a vertical axis from a plurality of tools, said working tool being placed in an operating position and having a line of travel normal to the work piece surface; (ii) orienting the working tool die about said vertical axis; (iii) maintaining the orientation of the working tool die during stamping travel; and (iv) controlling the orientation of the other tools in the turret; wherein the orientation of the working tool and the other tools are controlled with one stepper motor; (b) movable support means for holding the work piece which is capable of positioning the work piece in relation to the operating position of the working tool; whereby a selected position on the surface of the work piece is positioned along the line of travel of the working tool; (c) plunger means for striking said working tool into the work piece thereby stamping the die of the working tool into the surface of the work piece; (d) computer means for: (i) selecting the working tool; (ii) orienting the die of the working tool; (iii) positioning the work piece in relation to the working tool; and (iv) controlling and actuating the plunger means to stamp the die onto the work piece; and (e) computer means for controlling and repeating steps (a) to (d) until the design is stamped into the surface of the work piece.
Claim 3
Dependent Claim
165 words
The apparatus of claim 1 wherein the stepper motor driven turret means for selecting and orienting the working tool comprises a stepper motor driven planetary gear system comprising a sun gear operatively engaged with a plurality of planet gears each operatively connected to a separate tool slidably passing through a base of the planetary gear system wherein a first stepper motor selects a working tool from a plurality of tool positions by rotating the base of the planetary gear system which positions the planet gears in relation to the sun gear and the plunger means; a second stepper motor operatively connected to the sun gear, orients the working tool and all non-working tools simultaneously while the first stepper motor prevents undesirable rotation of the base of the planetary gear system; and a plunger means which drives the working tool and the planet gear in operative connection therewith, said planet gear being slidably engaged with the sun gear thereby preventing reorientation of the die during translation.
Claim 4
Dependent Claim
12 words
The apparatus of claim 2 wherein the work piece is a candle.
Claim 5
Dependent Claim
119 words
The apparatus of claim 3 wherein a first stepper motor means drives the base of a planetary gear system turret to select a working tool from a plurality of tools into the operating position; a second stepper motor means drives the sun gear of said planetary gear system to simultaneously orient the working tool and the non-working tools; a third stepper motor means drives a chuck holding the candle to position the candle rotationally in relation to the working tool said chuck being attached to a movable platform; a fourth stepper motor means positions said movable platform linearly in relation to the working tool, and a linear solenoid means drives the die of the working tool into the candle.
Claim 6
Dependent Claim
21 words
The apparatus of claim 2 wherein the planetary gear system turret supports a plurality of tools each having a different die.
Claim 7
Dependent Claim
147 words
A process for stamping a predetermined ornamental design into the surface of a candle comprising; (a) selecting and angularly orientating a working tool from a plurality of tools, each tool having a die thereon; (b) selecting a location on said candle to receive the stamp of the working tool die, the candle being mounted on a motorized rotational chuck mounted on a motorized linear platform; (c) stamping said die of said working tool into the candle positioned to receive said die; (d) controlling, by computer means, the selection of the working tool, the angular orientation of the working tool, the linear and angular position of the candle in relation to the working tool and the stamping of the die of the working tool into the candle; and (e) repeating steps (a) to (d) until a predetermined ornamental design has been stamped into the surface of the candle.
