Self service key duplicating machine with automatic key model identification system
An automatic key duplicating machine is disclosed. A master key identification module includes at least one key blade cross-section detector with a plurality of sliding elements, the master key identification module being configured to determine a key type for a master key based at least in part on engagement of the plurality of sliding elements with a blade profile of the master key. A key extraction module is configured to retrieve a key blank of an identified key type. A key cutting module is configured to cut the key blank in accordance with a tooth pattern of the master key.
1. An automatic key duplicating machine, comprising:
a master key identification module including at least one key blade cross-section detector with a plurality of sliding elements configured to slide in a thickness direction of the master key, the master key identification module being configured to determine a key type for a master key based at least on engagement of the plurality of sliding elements with at least one side of a blade profile of the master key;
a key extraction module configured to retrieve a key blank of an identified key type; and
a key cutting module configured to cut the key blank in accordance with a tooth pattern of the master key.
2. The automatic key duplicating machine of claim 1 , wherein the master key identification module further includes a blade length sensor configured to determine a length of the master key, wherein the key type for the master key is also determined based on the length.
3. The automatic key duplicating machine of claim 1 , further comprising:
a master key clamping module configured to receive and secure the master key.
4. The automatic key duplicating machine of claim 1 , wherein the plurality of sliding elements include a plurality of sliding element pairs, each of the plurality of sliding element pairs having a profile corresponding to a different key type.
5. A method of automatically duplicating a master key, comprising:
moving a plurality of sliding elements in a thickness direction of the master key such that the elements engage with a blade of the master key;
determining a key type for the master key based at least on engagement of the plurality of sliding elements with at least one side of a blade profile of the master key;
retrieving a key blank of an identified key type; and
cutting the key blank in accordance with a tooth pattern of the master key.
6. The method of claim 5 , further comprising:
determining a length of the master key, wherein the key type for the master key is also determined based on the length.
7. The method of claim 5 , wherein the plurality of sliding elements include a plurality of sliding element pairs, each of the plurality of sliding element pairs having a profile corresponding to a different key type.
