Abstract
Abstract A new and improved automatic label printing apparatus for printing a label onto various types and shapes of packages and containers including a probe unit adapted to have mounted therewith a printing head. The probe unit is mounted for movement in three mutually perpendicular directions for locating a printable area on a container and for thereafter indexing the probe and printing head over the printable area for applying a label thereto. The probe unit is releaseably mounted to break away from its normal directional movement in order to prevent probe damage. In an alternate embodiment of this invention, a label printing apparatus is provided for printing a label onto a curved surface. And, in a further alternate embodiment, label printing apparatus is provided for printing a label at a rate coordinated with conveyor speed.

Claim 3
Dependent Claim
34 words
The structure set forth in claim 1, including: said third axis being vertical; and means continuously urging said carriage assembly upwardly in order to at least partially neutralize the weight of said carriage assembly.
Claim 4
Dependent Claim
47 words
The structure set forth in claim 1, wherein said third axis mount means includes: an endless belt drive supported by spaced pulley members; means attaching said carriage assembly to said endless belt drive; and power means for driving one of said pulleys for rotating said belt drive.
Claim 5
Dependent Claim
48 words
The structure set forth in claim 3, including: said power means includes a drive shaft operably connected to one of said spaced pulley means; and said drive shaft having a torsion spring mounted therewith for urging said carriage assembly upwardly to neutralize the weight of said carriage assembly.
Claim 6
Dependent Claim
73 words
The structure set forth in claim 1, wherein said second axis mount means includes: a support rod extending parallel to said second axis; said carriage assembly including a carriage frame mounted for movement along said support rod; second axis drive means including an endless belt mounted on pulleys which are oriented along said second axis; and connector means connecting said carriage frame to said endless belt for bi-directional movement along said second axis.
Claim 7
Dependent Claim
50 words
The structure set forth in claim 5, wherein said connector means includes: pivot means for pivotally connecting said carriage frame to said endless belt; and means mounting said pivot means for movement along said third axis whereby said carriage frame reciprocates in response to continuous movement of said endless belt.
Claim 8
Dependent Claim
61 words
The structure set forth in claim 1, wherein said break-away means includes: pivot means mounting said probe unit onto said carriage assembly for pivotal movement with respect thereto; and means releaseably maintaining said probe unit in position for movement along said first axis, said probe unit being released for pivotal movement in response to said probe unit engaging an undesirable resistance.
Claim 9
Dependent Claim
100 words
The structure set forth in claim 1, including: a carriage assembly including a carriage frame mounted for movement along said second axis; said break-away means including a break-away platform having said probe unit and probe unit mount means mounted therein; pivot means pivotally mounting said break-away platform for pivotal movement with respect to said carriage frame; and detent means releaseably holding said break-away platform in position for said probe unit to move along said first axis and for releasing said break-away platform for pivotal movement away from said first axis in response to said probe unit engaging an undesirable force.
Claim 10
Dependent Claim
50 words
The structure set forth in claim 1, including: said probe unit including an elongated housing supporting said printing head; said elongated housing having a rack gear mounted therewith; and probe drive means including a gear drive for engaging said rack gear for moving said probe unit along said first axis.
