Abstract

According to one implementation, a drilling machine includes at least one drilling structure, a travelling machine, a reader and a controlling device such as a controlling circuit. The at least one drilling structure drills an object to be drilled. The travelling machine positions the at least one drilling structure in a travelling direction of the travelling machine by travelling in a direction different from a drilling direction. The reader reads information recorded on at least one integrated circuit tag attached to at least one drilling plate attached to the object to be drilled. The controlling device controls the travelling machine based on the information read by the reader.

First claim

What is claimed is:

1. A drilling machine comprising:
at least one drilling structure that drills an object to be drilled;
a travelling machine that positions the at least one drilling structure in a travelling direction of the travelling machine by travelling in a direction different from a drilling direction;
a reader that reads information recorded on at least one integrated circuit tag attached to at least one drilling plate attached to the object to be drilled;
a sensor that detects a position of the at least one drilling plate; and
a controlling circuit that controls the travelling machine based on the information read by the reader and the detected position of the at least one drilling plate.

2. The drilling machine according to claim 1 ,
wherein the controlling circuit comprises:
storage that stores information showing a relationship between pieces of identification information of drilling plates and drilling positions;
a control signal generation part that obtains a piece of identification information of one drilling plate by wireless, generates a control signal for controlling the travelling machine to position the at least one drilling structure on at least one drilling position specified based on the obtained piece of the identification information of the one drilling plate and the information stored in the storage, and transmits the generated control signal by wireless, the piece of the identification information of the one drilling plate having been read by the reader; and
a control signal receiver that receives the control signal by wireless and gives the received control signal to the travelling machine,
wherein the control signal receiver is placed on the travelling machine while the storage and the control signal generation part are placed outside the travelling machine.

3. The drilling machine according to claim 1 ,
wherein the travelling machine is configured to travel using a structural object as a guide, the structural object being included in the object to be drilled.

4. A method of manufacturing a drilled product, using the drilling machine according to claim 1 .

5. A drilling machine comprising:
at least one drilling structure that drills an object to be drilled;
a travelling machine that positions the at least one drilling structure in a travelling direction of the travelling machine by travelling in a direction different from a drilling direction;
a reader that reads information recorded on at least one integrated circuit tag attached to at least one drilling plate attached to the object to be drilled; and
a controlling circuit that controls the travelling machine based on the information read by the reader,
wherein the at least one drilling structure comprises:
a first drilling structure that drills a hole having a first diameter; and
a second drilling structure that drills a hole having a second diameter different from the first diameter,

wherein the first drilling structure is configured to drill the hole having the first diameter in an outward path of the reciprocating travelling machine while the second drilling structure is configured to drill the hole having the second diameter in a return path of the travelling machine.

6. The drilling machine according to claim 5 , further comprising:
a sensor that detects a position of an end portion of the at least one drilling plate,
wherein the controlling circuit is configured to control the travelling direction of the travelling machine based on the position of the end portion of the at least one drilling plate detected by the sensor.

7. The drilling machine according to claim 6 ,
wherein the at least one integrated circuit tag comprises:
a first integrated circuit tag attached on an end portion of the at least one drilling plate in a start side of the outward path of the travelling machine; and
a second integrated circuit tag attached on an end portion of the at least one drilling plate in a start side of the return path of the travelling machine,
wherein the reader is configured to read first information from the first integrated circuit tag and second information from the second integrated circuit tag, the first information being for specifying a first drilling position of the hole having the first diameter, the second information being for specifying a second drilling position of the hole having the second diameter; and
the controlling circuit is configured to control the travelling machine to position the first drilling structure at the first drilling position of the hole having the first diameter while the controlling circuit is configured to control the travelling machine to position the second drilling structure at the second drilling position of the hole having the second diameter.

8. The drilling machine according to claim 7 ,
wherein the at least one drilling plate comprises drilling plates attached to the object to be drilled in the travelling direction of the travelling machine; and
the reader is configured to read the first information from the first integrated circuit tag and the second information from the second integrated circuit tag, for every drilling plate.

9. The drilling machine according to claim 8 ,
wherein the controlling circuit is configured to reset a reference position for every drilling plate in order to control the travelling machine.

10. The drilling machine according to claim 5 ,
wherein the at least one integrated circuit tag comprises:
a first integrated circuit tag attached on an end portion of the at least one drilling plate in a start side of the outward path of the travelling machine; and
a second integrated circuit tag attached on an end portion of the at least one drilling plate in a start side of the return path of the travelling machine,
wherein the reader is configured to read first information from the first integrated circuit tag and second information from the second integrated circuit tag, the first information being for specifying a first drilling position of the hole having the first diameter, the second information being for specifying a second drilling position of the hole having the second diameter; and
the controlling circuit is configured to control the travelling machine to position the first drilling structure at the first drilling position of the hole having the first diameter while the controlling circuit is configured to control the travelling machine to position the second drilling structure at the second drilling position of the hole having the second diameter.

11. The drilling machine according to claim 10 ,
wherein the at least one drilling plate comprises drilling plates attached to the object to be drilled in the travelling direction of the travelling machine; and
the reader is configured to read the first information from the first integrated circuit tag and the second information from the second integrated circuit tag, for every drilling plate.

12. The drilling machine according to claim 11 ,
wherein the controlling circuit is configured to reset a reference position for every drilling plate in order to control the travelling machine.

13. The drilling machine according to claim 5 ,
wherein the at least one drilling plate comprises drilling plates attached to the object to be drilled in the travelling direction of the travelling machine;
the reader is configured to read information, showing an attachment order of the drilling plates to the object to be drilled, from the at least one integrated circuit tag attached to each of the drilling plates; and
the controlling circuit is configured to output error information when the information showing the attachment
