- FIG. 1 is an external view of an electric driver according to a first embodiment of the present invention. It is a functional block diagram of the electric driver of FIG. It is a figure which shows the condition setting data preserve
- the electric driver (tool) 100 As shown in FIGS. 1 and 2, the electric driver (tool) 100 according to the first embodiment of the present invention is rotated by the tool housing 110, the electric motor 112 built in the tool housing 110, and the electric motor 112. And a driven bit holder 114. A driver bit 116 appropriately selected according to a target screw is removably attached to the bit holder 114.
- the tool housing 110 is provided with an input interface 122 having a display unit 118 and an input button 120, and a connection cable 124 for connecting the motor-driven driver 100 to a programmable logic controller (PLC) 123.
- PLC programmable logic controller
- a motor drive circuit 126 for controlling the drive of the electric motor 112 a control circuit 128 for controlling the entire electric driver 100, and a rotational position of the rotor of the electric motor 112 are detected. Hall sensors 130 are provided.
- the control circuit 128 includes an arithmetic unit 131 and a memory (information storage unit) 132 in which setting data is stored.
- the calculation unit 131 controls the motor-driven driver 100 based on the setting data stored in the memory 132.
- the setting data stored in the memory 132 includes condition setting data for setting control conditions in each work process.
- the memory 132 of the motor-driven driver 100 can store first to thirtieth condition setting data corresponding to the first to twentieth work processes.
- the condition setting data includes setting values indicating the tightening torque and the number of tightening screws in the screw tightening operation. Besides these, for example, setting values for controlling the rotational speed of the electric motor 112 can also be included.
- the condition setting data in the motor-driven driver 100 further includes a pass reference value indicating a pass standard for the operation of the motor-driven driver 100 in each work process.
- set values for setting the minimum rotation time and the maximum rotation time of the electric motor 112 when the screw tightening operation is performed are included as the pass reference values. For example, when the rotation of the electric motor 112 is stopped in a time shorter than the minimum rotation time, it is expected that the head of the screw is seated earlier than the expected time, and the electric motor 112 in the time longer than the maximum rotation time. It is expected that when the rotation has stopped the screw head has been seated later than expected. That is, when the electric motor 112 is stopped earlier than the minimum rotation time or later than the maximum rotation time, it can be determined that there is a high possibility that the wrong screw is selected and screwing is performed.
- the condition setting data further includes a pass signal output setting value for setting whether or not to output a pass signal to the outside when the pass criteria are satisfied.
- the calculation unit 131 can output a pass signal when it is determined that the operation of a certain work process satisfies the pass criteria, but whether to output a pass signal depends on the pass signal output setting value It is determined.
- the pass signal output setting value is a setting value (ON) for outputting a pass signal
- the pass signal is output to the PLC 123
- a setting value (OFF) for not outputting a pass signal
- the pass signal is It does not output to PLC123.
- the setting data further includes a plurality of order setting data for setting the execution order of the work process.
- the first to thirtieth execution orders can be set in the memory 132 of the motor-driven driver 100, and data indicating each execution order is stored in the memory 132 as order setting data. There is. Up to eight work processes can be registered in each order setting data.
- the order setting data further includes a next operation setting value for setting the next operation after the series of work processes are completed.
- a setting value (termination) for stopping the operation of the electric driver 100 a setting value (loop) for re-executing a series of work processes in the same execution order, and It is possible to select from setting values (transition to another execution order) to shift to a series of work processes in the execution order based on the order setting data.
- condition setting data and order setting data included in the setting data can be arbitrarily changed by the operation of the input interface 122.
- setting data can be rewritten by transmitting corresponding data from an external device such as a personal computer.
- the calculation unit 131 reads necessary setting data from the memory 132. Which one of the plurality of execution orders is to be executed can be arbitrarily selected, and is usually specified in advance.
- the arithmetic unit 131 reads predetermined order setting data corresponding to the specified execution order, and sets the execution order of the work process. For example, when the first execution order is specified, the first order setting data is read, and as shown in FIG. 4, the first operation process, the second operation process, the third operation process, and the fourth operation process Are set as a series of work processes, and these work processes will be sequentially performed.
- the calculation unit 131 operates the electric driver 100 while sequentially changing the control conditions for each work process based on the first to fourth condition setting data respectively corresponding to the work processes.
- the first work process assumes that four screws are temporarily tightened
- the second work process assumes that the temporarily tightened screws are completely tightened. . Therefore, when the first work process is normally completed, the four screws are screwed in with their heads not seated, and in the second work process, these temporarily tightened screws are further screwed to seat the screw heads. Further tightening is performed with a predetermined tightening torque. As a result, the four screws are completely tightened.
- the computing unit 131 Since the pass signal output setting value of the first condition setting data is “OFF”, the computing unit 131 does not output a pass signal even if the first work process is normally completed and the pass criteria are satisfied. On the other hand, since the pass signal output setting value of the second condition setting data is "ON”, the computing unit 131 outputs a pass signal when the second operation process is normally completed and the pass criteria are satisfied. Similarly, in the third operation process, eight screws are temporarily tightened, and in the fourth operation process, the temporarily tightened eight screws are fully tightened, and when the fourth operation process is normally completed. A pass signal is output. Since the next operation setting value in the first order setting data is “end”, the operation of the electric driver 100 is stopped when the fourth operation process is completed.
- the pass signal is not output at the completion of the first and third working steps which are the temporary tightening step, but is output only when the second and fourth working steps which are the final tightening step are completed.
- PLC 123 will only receive a pass signal when screw tightening is complete.
- the PLC 123 controls the operation of the other peripheral devices etc. in conjunction with the operation of the electric driver 100, but does not necessarily perform some control every time each work process is completed, and a predetermined work process Control is often performed only when it is completed.
- a pass signal is outputted every time each work process is completed, and therefore, it is necessary to set the PLC 123 side so as to ignore an unnecessary pass signal.
- the second order setting data is read, and the third operation process, the 30th operation process, and the 7th operation process are set as a series of operation processes, for each operation process.
- the electric driver 100 operates while sequentially changing the control conditions. Since the next operation setting value in the second order setting data is "loop", when the seventh operation process which is the last operation process is completed, the process returns to the third operation process which is the first operation process, and so on. The work process will be repeated.
- the third order setting data is read, and eight operation steps from the first first operation step to the last thirteenth operation step are set as a series of operation steps.
- the electric driver 100 operates while sequentially changing the control conditions for each work process. Since the next operation setting value in the third order setting data is "transition to the fourth execution order", when the final thirteenth working process is completed, the designated fourth order setting data is read and the fourth execution order Are set, and the process shifts to a series of work steps in the fourth execution order.
- the next operation after completion of a series of work steps based on certain order setting data can be selected from “end", "loop", and "transition to another execution order".
- the electric driver 100 since it is possible to shift to an execution order based on another order setting data, the electric driver 100 itself sets a work process in a more complicated execution order without depending on control of an external device such as the PLC 123. It is possible to In addition, if the basic execution order that is often used is set in each order setting data, setting the execution order to be shifted appropriately as compared with the case where the execution order is reassembled from the beginning Thus, process changes can be made more quickly and easily. It is not necessary to necessarily include the above-described three as the selectable next operation, and may include another next operation instead or additionally.
- the motor-driven driver 100 is further configured to store in the memory 132 a history of work processes executed across a plurality of execution orders based on a plurality of order setting data. Due to some work errors, it may be necessary to redo the work process or, in some cases, to start from the previous work process. In that case, based on the history of the work process stored in the memory 132, it is possible to return to the work process that needs to be redone. Specifically, by operating the input button 120 of the input interface 122, it is possible to return to the previous work process remaining in the history.
- the operation of the input button 120 returns only one work in the current work process, returns to the previous work process, returns to the last work process in the execution sequence of the previous order setting data, or It is possible to return to the first work process in the execution order of the previous order setting data.
- the memory 132 in the motor-driven driver 100 is a combination of a readable and writable non-volatile memory and a volatile memory such as a cache memory for temporarily storing data necessary for the program operation.
- the setting data is stored in the non-volatile memory, and the work process history is stored in the volatile memory.
- An electric driver 200 includes an electric driver main body 202 and a controller 204 for controlling the electric driver main body 202, as shown in FIGS.
- the motor-driven driver main body 202 and the controller 204 are connected by a communication cable 206 via communication units 238 a and 238 b respectively provided.
- a communication cable 224 connected to the PLC 223 is provided on the controller 204 side.
- an electric motor 212, a motor drive circuit 226, and a hall sensor 230 similar to the electric driver 100 according to the first embodiment are provided.
- the input interface 222 is provided on the controller 204 side.
- calculation units 231a and 231b are provided in the electric driver main body 202 and the controller 204, respectively.
- the two arithmetic units 231a and 231b communicate with each other via the communication cable 206, and the two arithmetic units 231a and 231b perform the same function as the arithmetic unit 131 in the first embodiment.
- memories 232a and 232b are respectively provided in the motor-driven driver main body 202 and the controller 204, and these two memories 232a and 232b perform the same function as the memory 132 in the first embodiment. That is, in the motor-driven driver, the control circuit 228 is dispersedly disposed in the motor-driven driver main body 202 and the controller 204.

It is also possible to use other power tools such as an air tool that uses an air motor instead of an electric motor as a power source while having a control circuit such as the above.
- the tool according to the invention can also be a hand tool without power. As such a hand tool, for example, there is a torque wrench having a torque detection function.
