Abstract

A work management data collection system 1 is provided with a data collection mechanism in a tool 2, and by counting a number of times a work operation has been executed or the like, obtains a work data identifying the work task that has been executed and detects a time data required for the work task. The system is provided with an RFID tag 3a on an ID card 3 held by a worker, and by writing data into the ID card 3 of the worker who carried out the work task, using an RFID reader/writer 4 provided on the tool 2, the system obtains data necessary for the work management from the ID card 3 of the worker.

Claims

1. A portable tool comprising;

a work data acquisition device configured to obtain a work data which identifies a work task that has been performed;

a storage device configured to store the work data obtained by the work data acquisition device;

a clocking device configured to clock a working time;

a read and write device configured to read and write data into an external data storage device which is independent from the portable tool;

a control device configured to identify a worker by reading out a worker identification data using the read and write device, and write the work data stored on the storage device and a working time data clocked by the clocking device into the external data storage device using the read and write device; and

a consumable supply container which contains a consumable supply used during the work task, and which can freely be attached to and removed from the body of the portable tool;

wherein the external data storage device comprises a consumable supply data storage device provided on the consumer supply container, the consumable supply data storage device storing a consumable supply identification data identifying a type of the consumable supply and a consumable supply quantity data;

the control device identifies the type of the consumable supply by reading out the consumable supply identification data and the consumable supply quantity data using the read and write device,

the control device recognizes the quantity of the consumable supply before the work task is carried out, the control device calculates a remaining quantity of the consumable supply left within the consumable supply container from a number of the consumable supply used while the work task is carried out, and

the control device writes the remaining quantity data of the consumable supply into the consumable supply data storage device of the consumable supply container using the read and write device.

2. A portable tool comprising:

a work data acquisition device configured to obtain a work data which identifies a work task that has been performed;

a storage device configured to store the work data obtained by the work data acquisition device;

a clocking device configured to clock a working time;

a read and write device configured to read and write data into an external data storage device which is independent from the portable tool; and

a control device configured to identify a worker by reading out a worker identification data using the read and write device, and write the work data stored on the storage device and a working time data clocked by the clocking device into the external data storage device using the read and write device,

wherein the portable tool is a screwing machine.

3. The portable tool according to claim 2, wherein the external data storage device comprises an ID card of the worker, and

the control device writes the work data and the working time data into the ID card of the worker identified by the worker identification data using the read and write device.

4. The portable tool according to claim 2, wherein the external data storage device comprises a wireless tag which transmits and receives data wirelessly, and

the read and write device reads and writes data through wireless communications.

5. A portable tool comprising:

a work data acquisition device configured to obtain a work data which identifies a work task that has been performed;

a storage device configured to store the work data obtained by the work data acquisition device;

a clocking device configured to clock a working time;

a read and write device configured to read and write data into an external data storage device which is independent from the portable tool; and

a control device configured to identify a worker by reading out a worker identification data using the read and write device, and write the work data stored on the storage device and a working time data clocked by the clocking device into the external data storage device using the read and write device,

wherein the portable tool is a nailing machine.

6. The portable tool according to claim 5, wherein the external data storage device comprises an ID card of the worker, and

the control device writes the work data and the working time data into the ID card of the worker identified by the worker identification data using the read and write device.

7. The portable tool according to claim 5, wherein the external data storage device comprises a wireless tag which transmits and receives data wirelessly, and

the read and write device reads and writes data through wireless communications.

8. A work management data collection system for collecting data necessary for work management of work tasks, wherein a portable tool used for the work tasks comprises:

a work data acquisition device configured to obtain a work data which identifies a work task that has been performed;

a storage device configured to store the work data obtained by the work data acquisition device;

a clocking device configured to clock a working time;

a read and write device configured to read and write the data into an external data storage device which is independent from the portable tool; and

a control device configured to identify a worker by reading out a worker identification data using the read and write device, and write the work data stored on the storage device and the working time data clocked by the clocking device into the external data storage device using the read and write device,

wherein the portable tool is one of a screwing machine and a nailing machine.
