Processing apparatus of processing wafer sheets

A processing apparatus comprising:

• one or more processing parts for processing plural sheets of objects to be processed;
• a rotary processing part for collectively rotating and drying said objects processed by said processing parts;
• a balance adjusting mechanism having at least one counterweight for adjusting the balance of said rotary processing part by moving said at least one counterweight in accordance with the number of said objects;
• counting means for counting the number of said objects before said objects are processed by said processing parts;
• and
• control means for controlling the balance adjusting operation by said balance adjusting mechanism in accordance with a predetermined relationship between the number of said objects and respective positions of said at least one counterweight, wherein
• said control means controls said balance adjusting mechanism in a manner so that the balance adjusting operation of said balance adjusting mechanism is finished by the time said objects are accommodated in said rotary processing part, wherein
• a period provided from a beginning of the balance adjusting operation to the end is represented by a letter A, while a period from a beginning of transferring said object from a former processing part just before said rotary processing part, to said rotary processing part to the end of transferring, after which said objects are able to be rotary-processed, is represented by a letter B, and wherein
• said control means is constructed so that, in case of A.ltoreq.B, the transferring of said objects into said rotary processing part is started as soon as the balance adjusting operation has been started, while in case of A>B, the objects wait for at least a time AB since the balance adjusting operation was started, at the former processing part just before said rotary processing part, then the transferring of said objects into said rotary processing part is started.

A processing apparatus comprising:

• a rotary processing part for rotating and drying plural sheets of objects to be processed collectively;
• a balance adjusting mechanism having at least one counterweight for adjusting the balance of said rotary processing part by moving said at least one counterweight in accordance with the number of said objects;
• counting means for counting the number of said objects accommodated in said rotary processing part;
• and
• control means for controlling the balance adjusting operation by said balance adjusting mechanism in accordance with a predetermined relationship between the number of said objects and respective positions of said at least one counterweight, wherein
• said control means controls said balance adjusting mechanism in a manner so that the balance adjusting operation of said balance adjusting mechanism is finished by the time said objects are accommodated in said rotary processing part, and wherein
• said predetermined relationship between the number of said objects and the position of said at least one counterweight is introduced from a predetermined relationship between the number of said objects and resultant force of said at least one counterweight, and wherein,
• providing that the number of said objects is represented by a variable x while the resultant force is represented by a variable y, and certain constant values are represented by constants a and b, said predetermined relationship between the number of said objects and the resultant force is expressed by an equation as below:
• y=ax+b.
