Puck wear detection
View Patent ↗A transport puck vertically aligns a caulking cartridge, nozzle-down. The puck includes (i) a substantially solid lower plug portion, having a lead face and a bottom face and an center passageway that is at least partially inverted frustum-shaped that forms a side contact face that tapers from a wider lead face opening to a narrower bottom face opening; and or to a tubular sleeve from the side contact face to the bottom face opening; (ii) an upper sleeve, shaped to receive the caulking cartridge in a desired vertical alignment to the lower plug portion; and (iii) at least one funnel-shaped bore into the bottom face with an inserted connector comprising a head and stem, the head spaced within the bore to define a spacing that has been determined to identify bottom face wear.
1. A nozzle-down cartridge transport puck to detect surface wear, comprising:
(i) an upper sleeve, shaped to receive a caulking cartridge, nozzle-down in vertical alignment to a lower plug portion; and
(ii) a substantially solid lower plug portion, comprising
a lead face and a bottom face for stable contact and frictional engagement with level planar surface;
a center passageway at least partially shaped with a side contact stop collar that includes a surface that tapers from a wider lead surface opening to a narrower bottom surface opening or to a tubular sleeve from the side contact face to the bottom face opening; and
at least one funnel-shaped bore into the bottom face with an inserted connector comprising a head and stem, the head spaced within the bore to define a spacing that has been determined to identify bottom face wear.
2. The nozzle-down cartridge transport puck of claim 1 , wherein the head of the connector has an indicator that visually contrasts with the bottom face surface.
3. The nozzle-down cartridge transport puck of claim 1 , wherein the substantially solid lower plug portion having a lead face and a bottom, includes a nozzle receiving channel having a shaped center passageway that defines an inclined side contact face tapering from a wider lead face opening to a narrower bottom face opening.
4. The nozzle-down cartridge transport puck of claim 1 , wherein the substantially solid lower plug portion having a lead face and a bottom includes a nozzle receiving channel in the form of an inverted frustum-shaped or modified frustum shaped center passageway that defines an inclined side contact face that tapers from a wider lead face opening to as narrower bottom face opening and the tapering contact face defines a plane that forms an acute angle at least greater than 15° at intersection with a plane of the lead face.
5. The nozzle-down cartridge transport puck of claim 1 , wherein the substantially solid lower plug portion having a lead face and a bottom defines a nozzle receiving channel in the form of an inverted frustum-shaped or modified frustum shaped center passageway that defines an inclined side contact face that tapers from a wider lead face opening to a narrower bottom face opening and the tapering contact face defines a plane that forms an acute angle between 20° to 75° at intersection with a plane of the lead face.
6. The nozzle-down cartridge transport puck of claim 1 , wherein the substantially solid lower plug portion having a lead face and a bottom defines a nozzle receiving channel in the form of an inverted frustum-shaped or modified frustum shaped center passageway that defines an inclined side contact face that tapers from a wider lead face opening to a narrower bottom face opening and the tapering contact face defines a plane that forms an acute angle between 40° to 60° at intersection with a plane of the lead face.
7. The nozzle-down cartridge transport puck of claim 1 , wherein an intersection of a plane of the lead face and the plane of the side contact face defines an acute between 20° to 75°.
8. The nozzle-down cartridge transport puck of claim 1 , wherein an intersection of a plane of the lead face and the plane of the side contact face defines an acute angle between 40° to 60°.
9. The nozzle-down cartridge transport puck of claim 1 wherein the lower plug portion has a weight and the bottom face has a breadth to maintain a center of gravity of the puck and a filled caulking cartridge, below a plane passing through any single fulcral point or edge of the bottom face and extending upward through the sleeve from the level planar surface at an angle of about 60°.
10. The nozzle-down cartridge transport puck of claim 1 wherein the lower portion comprises a material having a specific gravity greater than about 2.
11. The nozzle-down cartridge transport puck of claim 1 wherein the upper sleeve comprises a material having a specific gravity of less than 2.
12. The nozzle-down cartridge transport puck of claim 1 wherein the upper sleeve to lower portion weight ratio is a maximum of about 2/3.
13. The nozzle-down cartridge transport puck of claim 1 wherein the upper sleeve to lower portion height ratio is greater than about 3/2.
14. The nozzle-down cartridge transport puck of claim 1 wherein the lower portion comprises materials selected from the group consisting of metal filled plastic.
15. The nozzle-down cartridge transport puck of claim 1 wherein the upper sleeve comprises materials selected from the group consisting of plastic and wood.
16. The nozzle-down cartridge transport puck of claim 1 wherein the ratio of maximum height to maximum width exceeds about 1/1.
17. The nozzle-down cartridge transport puck of claim 1 wherein the head is signified by a contrasting head surface material or by an added pigment, paint or chalk.
18. A nozzle-down tilling system for filling cartridges with a viscous material, comprising a cartridge loading station comprising a transport puck adapted to receive the cartridge in a nozzle-down vertical alignment, the transport puck comprising (i) a substantially solid lower plug portion, having a lead face and a bottom face and a center passageway that is at least partially in the form of a side contact stop collar having a face that tapers from a wider lead face opening to a narrower bottom face opening or to a tubular sleeve from the side contact face to the bottom face opening; (ii) an upper channel, shaped to receive the caulking cartridge in the vertical alignment to the lower plug portion; and (iii) at least one funnel-shaped bore into the bottom face with an inserted connector comprising a head and stem, the head spaced within the bore to define a spacing that has been determined to identify bottom face wear;
a filling station adapted to receive the cartridge with a viscous material;
a capping station to cap the cartridge; and
a conveyor adapted to receive a cartridge dispensed by the loading station and for conveying the cartridge in turn to the filling station and then the capping station.
19. A method for filling a nozzled caulking cartridge comprising:
vertically aligning the cartridge in a transport puck, nozzle down, by an apparatus to unscramble and load the puck comprising (i) a substantially solid lower portion, having a bottom face for stable contact and frictional engagement with level planar surfaces, and attached thereto, opposite the bottom face, (ii) an upper sleeve, shaped to receive the caulking cartridge in a nozzle-down alignment; and (iii) at least one funnel-shaped bore into the bottom face with an inserted connector comprising a head and stem, the head spaced within the bore to define a spacing that has been determined to identify an extent of bottom face wear; wherein the lower portion has a weight and the bottom face has sufficient breadth to maintain the center of gravity of the puck and filled caulker, below a tipping plane;
transporting the puck to an apparatus for filling the caulking cartridge;
filling the cartridge; and
capping the cartridge.
20. The nozzle-down filling system for filling cartridges with a viscous material of claim 18 , wherein the head of the connector has an indicator that visually contrasts with the bottom face surface.
