Continuous casting process for making golf balls
View Patent ↗A system includes a dispensing station and top and bottom mold portion paths. The dispensing station is configured to dispense materials into one or more hemispherical cavities of a plurality of top mold portions and a plurality of bottom mold portions. The plurality of top mold portions are conveyed at a first speed along the top mold portion path, and the plurality of bottom mold portions are conveyed at a second speed along the bottom mold portion path. The dispensing station can include at least one nozzle coupled to a six-axis robotic member that is configured to move at variable speeds.
1. A system for forming golf balls comprising:
a dispensing station configured to dispense materials into one or more hemispherical cavities of a plurality of top mold portions and a plurality of bottom mold portions;
a top mold portion path along which the plurality of top mold portions are conveyed at a first speed along the top mold portion path; and
a bottom mold portion path along which the plurality of bottom mold portions are conveyed at a second speed along the bottom mold portion path;
wherein the dispensing station comprises at least one nozzle coupled to a six-axis robotic member, the six-axis robotic member being configured to move along and between the top mold portion path and bottom mold portion path at variable speeds, the six-axis robotic member being configured to move at the first speed when dispensing material into the hemispherical cavities of the top mold portions, at the second speed when dispensing material into the hemispherical cavities of the bottom mold portions, and at a speed different from the first and second speeds when moving between the top mold portion path and bottom mold portion path.
2. The system of claim 1 , further comprising:
a first rotary index table for receiving top mold portions; and
a second rotary index table for receiving bottom mold portions,
wherein the first and second rotary index tables are configured to move in opposite directions to assemble respective top and bottom mold portions into mold assemblies.
3. The system of claim 2 , further comprising:
a core insert member configured to insert cores into the top or bottom mold portions as the top and bottom mold portions are received on the first and second rotary index tables.
4. The system of claim 3 , wherein the first rotary index table comprises a plurality of core insert members, each core insert members being associated with one of a plurality of hubs of the first rotary index table.
5. The system of claim 2 , wherein one of the first or second rotary index tables is configured to invert the top or bottom mold portion as it moves to a position for assembly of the top and bottom mold portions.
6. The system of claim 2 further comprising a curing station comprising an infrared heating system.
7. The system of claim 6 , wherein the infrared heating system comprises at least two different temperature zones.
8. The system of claim 6 , wherein the curing station comprises a serpentine path along which the mold assemblies are conveyed.
9. The system of claim 2 , further comprising a cooling station that utilizes cold compressed air to cool mold assemblies within the cooling station.
10. The system of claim 9 , wherein the cooling station comprises a rotary index table to move the mold assemblies in a generally circular manner.
11. The system of claim 2 , further comprising:
at least one physical ejection member configured to eject balls from the top or bottom mold assemblies; and
at least one sensor configured to determine whether balls have been properly ejected from the top or bottom mold assemblies.
12. The system of claim 2 , further comprising:
a detector system configured to obtain identifying information from the top and bottom mold portions of respective mold assemblies,
wherein the detector system is configured to compare the identifying information with predetermined mold matching information to determine whether the respective mold assemblies are properly matched.
13. A system for forming golf balls comprising:
a top mold portion path along which the plurality of top mold portions are conveyed at a first speed along the top mold portion path;
a bottom mold portion path along which the plurality of bottom mold portions are conveyed at a second speed along the bottom mold portion path;
a dispensing station configured to dispense materials into one or more hemispherical cavities of a plurality of top mold portions and a plurality of bottom mold portions, the dispensing station comprises at least one nozzle coupled to a six-axis robotic member, the six-axis robotic member being configured to move along and between the top mold portion path and bottom mold portion path at variable speeds, including at least at the first and second speeds;
a first rotary index table for receiving top mold portions; and
a second rotary index table for receiving bottom mold portions,
wherein the first and second rotary index tables are configured to move in opposite directions to assemble respective top and bottom mold portions into mold assemblies.
14. The system of claim 13 , wherein the six-axis robotic member is configured to move at the first speed when dispensing material into the hemispherical cavities of the top mold portions, at the second speed when dispensing material into the hemispherical cavities of the bottom mold portions, and at a speed different from the first and second speeds when moving between the top mold portion path and bottom mold portion path.
15. The system of claim 13 , further comprising:
a core insert member configured to insert cores into the top or bottom mold portions as the top and bottom mold portions are received on the first and second rotary index tables,
wherein one of the first or second rotary index tables is configured to invert the top or bottom mold portion as it moves to a position for assembly of the top and bottom mold portions.
