Abstract

A mixing machine includes a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool. A drive train including a motor having an output operatively connected to drive a planetary gear system that effects rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis. A control system includes a master control unit and a slave control unit, the master control unit connected with a first sensor located along the drive train between the motor and the planetary gear system, the slave control unit connected with a second sensor, wherein both the slave control unit and the second sensor rotate with a part of the planetary gear system, wherein the master control unit and the slave control unit are configured for wireless communication with each other.

First claim

What is claimed is:

1. A mixing machine, comprising:
a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool;
a drive train including a motor having an output operatively connected to drive a planetary gear system, where the planetary gear system effects rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis;
a user interface;
a control system including:
a master control unit connected with a first sensor located along the drive train between the motor and the planetary gear system, the master control unit also connected to the user interface;
a slave control unit connected with a second sensor, wherein both the slave control unit and the second sensor rotate with a part of the planetary gear system, wherein the master control unit and the slave control unit are configured for wireless communication with each other.

2. The mixing machine of claim 1 wherein the slave control unit and the second sensor are connected to be powered by a battery, wherein the battery rotates with the part of the planetary gear system.

3. The mixing machine of claim 2 wherein the second sensor includes a standby mode.

4. The mixing machine of claim 1 , further comprising a third sensor connected with the slave control unit, the third sensor rotates with the part of the planetary gear system.

5. The mixing machine of claim 4 , wherein the second sensor is a planetary oil level sensor and the third sensor is a planetary oil temperature sensor.

6. The mixing machine of claim 5 wherein the master control unit is configured to request data from the second sensor and the third sensor through the slave control unit.

7. The mixing machine of claim 6 wherein the master control unit is configured to store data obtained from the second sensor and the third sensor in an on-board historical database.

8. The mixing machine of claim 7 wherein the master control unit is configured to analyze data from the second sensor to identify whether (i) the planetary oil level is increasing over time and/or (ii) the planetary oil level is gradually decreasing and/or (iii) the planetary oil level is rapidly decreasing or has rapidly decreased and/or (iv) the planetary oil level fails to drop once mixer operation begins, and in the event of such an identification to generate an alert message.

9. The mixing machine of claim 7 wherein the master control unit is configured to analyze data from the third sensor to identify (i) a rapid rise in planetary oil temperature in excess of a threshold rate and/or (ii) a planetary oil temperature in excess of a threshold temperature, and in the event of such an identification to generate an alert message.

10. The mixing machine of claim 1 wherein the second sensor is a planetary oil level sensor, and the master control unit is configured to (i) obtain data from the second sensor through the slave control unit, (ii) store data obtained from the second sensor in an on-board historical database, and (iii) identify a condition in which the planetary oil level fails to drop once mixer operation begins, and in the event of such condition identification to generate an alert message indicating that a planetary oil pump has failed or is failing.
