DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show a first embodiment. 1, the game board 3 is positioned and mounted on the table 2 of the apparatus main body 1 with the design board surface of the game board 3 facing up, and a game board sensor (not shown) for detecting that the game board 3 has been positioned and mounted. Alternatively, any manual switch (not shown) that is turned on by the operator's operation in place of the game board sensor outputs the game board type signal and the nail driving start signal to the control unit 4 in which the computer is built. To do. Then, the computer extracts the driving position and order of the nail 5 from the nailing data 4a corresponding to the model of the game board 3 stored in the storage device of the control unit 4 in advance, The table driving unit 6 is controlled according to the above. The table driving unit 6 moves the table 2 in the X direction and Y direction as vertical and horizontal directions in a plane, and moves the predetermined position of the game board 3 to the nail holder mechanism 8 attached to the set plate 7 above and The positioning is stopped below the hammer mechanism 9. A number of nails 5 called game nails supplied from the nail supply unit 10 such as a parts feeder to the nail holder mechanism 8 are driven into the game board 3 by the hammer mechanism 9 to be hit on one game board 3. Are automatically driven into the game board 3 one by one.
[0007]
Each time this nail 5 is automatically driven into the game board 3, the detecting means 11 detects the form of the nail 5 that has been driven into the game board 3, such as a bend or a drive error, by image processing. A morphological abnormality signal is generated when the presence of a bend or a driving error 5 is detected.
[0008]
The detection means 11 of this embodiment detects, by image processing, the manner in which the nail 5 that has been driven into the game board 3 has been driven in the previous position immediately before the position in which the nail 5 has been driven into the game board 3. Since the abnormal shape signal is generated when the bending or driving error of the nail 5 is detected, the sensor head 11a provided on the set plate 7 is connected to the nail holder mechanism 8 and the hammer at a predetermined position of the game board 3. Each time the positioning is stopped below the mechanism 9, the sensor drive unit 11 b controlled by the control unit 4 is parallel to the table 2 with a predetermined vertical interval so as not to interfere with the nail 5 already driven into the game board 3. As shown in FIG. 2, the measurement light 11c emitted from the semiconductor laser is moved to the head of the nail 5 in one direction shown in FIG. of Irradiation is performed so as to scan in the direction (the same direction as either the X direction or the Y direction), and the reflected light is condensed on the position detection element to measure the measurement position data in the scanning direction and the measurement position data in the height direction. The signal converted into is output to the form determination unit 11d built in the control unit 4.
[0009]
The shape determination unit 11d collates the measurement position data in the scanning direction and the measurement position data in the height direction output from the sensor head 11a, and converts the shape of the irradiation field into a two-dimensional image. For example, in the case of a nail 5 that has been successfully driven, the converted measurement figure has the shape depicted by the phantom line L1 in FIG. 1b, and in the case of a nail 5 that has been bent and driven, In the case of a driving mistake in which the nail 5 has not been driven into the driving position, although not shown in the drawing, it has a straight line shape. Then, the form determination unit 11d compares the converted measurement figure with the reference figure set in advance in the form determination unit 11c (substantially the same shape as the measurement figure indicated by the virtual line L1 in FIG. 1b). It is determined whether the nail 5 is bent or misplaced, and if the measured figure is outside the allowable range including the reference figure, it is estimated that the nail 5 is bent or the nail 5 is misplaced. The signal is output to the configuration history unit 11e built in the control unit 4.
[0010]
The form history unit 11e correlates the driving position of the nail 5 that caused the generation of the abnormal shape signal and the measurement form based on the driving position and order of the nail 5 of the nail driving data executed by the control unit 4. The attached inspection data 11e-1 is stored, for example, in a form in which the first ceiling nail and its measurement figure are written together as shown in the form history part 11e in FIG. In the game board 3, the number of times that one or both of the nail 5 bends and driving mistakes occur discontinuously, or the nail 5 is given a preset number of times in the form history section 11e. , Or when either one or both of the bending and driving mistake of the nail 5 occur continuously, a mechanism abnormality signal is output to the control unit 4.
[0011]
As a result, the control unit 4 interrupts the subsequent nail driving operation and operates the alarm means 11f such as a buzzer, a lamp, or a sound generator (not shown) to generate an abnormal shape of the nail 5 driven into the operator. Notify that the nailing operation is interrupted. The control unit 4 stores the inspection data 11e-1 in the nail driving operation each time the form history unit 11e completes every nail driving operation for one game board 3 by the nail driving data 4a. If there is, the inspection data 11e-1 is output and displayed on one or both of the display 11g and the printer 11h.
[0012]
According to this embodiment, the predetermined position of the game board 3 is moved directly below the set of the nail holder mechanism 8 and the hammer mechanism 9 by the movement of the table 2, for example, from the starting point position a of the nail driving operation shown in FIG. By repeatedly moving and stopping to the end point b of the nail driving operation via the position, position B, position C, the nail 5 is driven into the game board 3 one by one in the position B, position B, position C. In this case, the sensor head 11a actually places the nail 5 in the game board as shown in the relationship between the stop position of the pair of the nail holder mechanism 8 and the hammer mechanism 9 and the stop position of the sensor head 11a as shown in FIG. The movement stops at the past position one position before the position to be driven into 3. First, when the set of the nail holder mechanism 8 and the hammer mechanism 9 is stopped at the starting point position a, the sensor head 11a is stopped at the initial position without performing the detection operation. This initial position is a position preset in the control unit 4 so that the sensor head 11a stops at both the nail holder mechanism 8 and the hammer mechanism 9 with a predetermined lateral distance. Next, when the pair of the nail holder mechanism 8 and the hammer mechanism 9 moves from the starting position a and stops at the position a, the sensor head 11a moves from the initial position without performing the detecting operation and stops at the starting position a. To do. Subsequently, when the pair of the nail holder mechanism 8 and the hammer mechanism 9 moves from the position A and stops at the position B, the sensor head 11a moves from the starting position a and stops at the position A, and then the detection operation is performed. When the pair of the nail holder mechanism 8 and the hammer mechanism 9 moves from the position B and stops at the position C, the detection operation is performed after the sensor head 11a moves from the position A and stops at the position B. Further, when the pair of the nail holder mechanism 8 and the hammer mechanism 9 moves from the position C and stops at the end position b, the sensor head 11a moves from the position B and stops at the position C, and after performing the detection operation. Return to the initial position.
[0013]
When the nail 5 is driven normally at each of the positions A to C, the control unit 4 continues the subsequent control operation without the form determining unit 11d generating a form abnormality signal.
[0014]
On the other hand, if the nail 5 is bent and driven at any of the positions i to c, or if the nail 5 does not exist at the driving position where the nail 5 is to be driven, the form determination unit 11d sends a form abnormality signal to the form history part. 11e, and the form history unit 11e stores the inspection data 11e-1, and every time a nail 5 is bent or a driving error occurs in one game board 3, or a bending or driving error of the nail 5 occurs. When the number of occurrences of one or both of them discontinuously reaches a predetermined number, or when one or both of the nails 5 are bent or driven mistakenly, the mechanism abnormality signal is transmitted to the control unit 4. , The control unit 4 interrupts the subsequent control operation and performs the notification operation of the notification means 11f. Then, an operator who has received the warning by the notification unit 11f is worn condition and the Horudaa over arm for supporting the nails 5 of the nail holder mechanism 8 examines the like axial runout of the hammer head driving a nail 5 of the hammer mechanism 9, If necessary, after performing repairs, the starting switch (not shown) is turned on to resume the nail driving operation, whereby the subsequent nail driving operation can be continued.
[0015]
Further, according to this embodiment, since the detecting means 11 detects the presence or absence of the bending of the nail 5 at the past position immediately before the nail driving position for driving the nail 5 into the game board 3, one sheet If the presence or absence of bending of the last nail 5 is detected after the nail driving operation on the game board 3 is completed, the nail driving operation and the inspection operation for one game board 3 are completed, and the nail driving time is reached. And the total time of inspection time can be shortened.
[0016]
Further, every time when all the nailing operations for one game board 3 are completed, when the inspection history data 11e-1 is stored in the form history section 11e, the inspection data 11e-1 By displaying one or both of the display 11g and the printer 11h and the like, the operator can quickly and accurately correct the corrected portion with reference to the output display from the display 11g and the printer 11h in the post-nail process. The bent nail 5 is removed from the game board 3 and a new nail 5 is driven into the removal position, or the bending of the nail 5 is corrected with a hand-held hammer. The nail 5 can be driven into the hand with a hammer.
[0017]
FIG. 5 shows a second embodiment, and the detection means 11 of this embodiment is driven by the nail 5 driven into the game board 3 at the driving position every time the nail 5 is driven into the game board 3. The form is detected by image processing, and a form abnormality signal is generated when a bending or driving error of the nail 5 is detected. The sensor head 11a can move the nail holder mechanism 8 to the set plate 7. The sensor head 11a is positioned at a predetermined position of the game board 3 below the nail holder mechanism 8 and the hammer mechanism 9 to stop the hammer. After the hammer 9 starts to rise after the driving operation of the nail 5 where the mechanism 9 descends, the predetermined position of the game board 3 is set as the next driving position below the set of the nail holder mechanism 8 and the hammer mechanism 9. Place Before starting the movement, the measurement light 11c emitted from the semiconductor laser is irradiated so as to scan the head of the nail 5, and the reflected light is condensed on the position detection element to obtain the measurement position data in the scanning direction. By outputting the signal converted into the measurement position data in the height direction to the form determining unit 11d built in the control unit 4 and detecting the driven form of the nail 5 immediately after being driven into the game board 3, 1 The inspection operation is completed simultaneously with the completion of the nail driving operation on the single game board 3, so that the total time of the nail operation and the inspection operation for one game board 3 can be shortened most. In particular, according to this embodiment, the structure can be simplified by omitting the sensor driving unit 11b shown in FIG.
[0018]
The measurement figure converted by the form determination unit 11d in each embodiment changes the scanning direction of the measurement light 11c with respect to the head of the nail 5, or the characteristics such as the measurable depth of the sensor head 11a, or the nail driving Depending on conditions such as allowable measurement time in the process, it is possible to obtain a shape as shown in FIG. 6, for example. That is, in FIG. 6A, when the nail 5 is driven normally, the head of the nail 5 is irradiated with measurement light as indicated by reference numeral 11c-1 and scanned in the front and back direction of the paper. The measurement figure has a shape drawn by a solid line L3 in FIG. Further, in FIG. 6a, when the nail 5 is bent and driven, when the head of the nail 5 is irradiated with measurement light as indicated by reference numeral 11c-2 and scanned in the front and back direction of the paper surface, The measurement figure is a shape drawn by a dotted line L4 in FIG. In addition, in the case of a driving mistake in which the nail 5 is not driven into the driving position, although it is not illustrated, it exhibits a linear shape. In short, one or both of the size and the position of the measurement figure are different from the reference figure, so that the presence of the nail 5 being bent or a driving error of the nail 5 can be determined by the form determination unit 11d. .
[0019]
In each embodiment, every time a nail 5 is bent or a driving error occurs, if the subsequent nail driving operation is interrupted, the number of maintenance inspections of the nail driving machine increases, but each time it is necessary for the nail driving machine. By performing the repair, it is possible to reduce the number of repaired parts where the nail 5 is bent or a driving error occurs. In particular, when a driving error occurs, the subsequent nail driving operation is immediately interrupted, so that, for example, the nail 5 that has fallen to the game board 3 from the nail holder mechanism 8 is subjected to the nail holder mechanism during the subsequent nail driving operation. 8 and the game board 3 are not caught, and the inconvenience that the dropped nail 5 damages the design board surface of the game board 3 can be solved.
[0020]
In each embodiment, the control unit 4, the notification unit 11 f, the display 11 g, and the printer 11 h are illustrated as being incorporated in the apparatus main body 1, but the control unit 4, the notification unit 11 f, the display 11 g and the printer 11 h are included in the apparatus main body. 1, the table drive unit 6, the sensor drive unit 11b, the notification unit 11f, the display 11g and the printer 11h are individually connected to the control unit 4 with electric wires, and the display 11g and the printer 11h are connected after the nailing process. Even if it is arranged in the nail bending correction area as a process, the same effect is obtained.
[0021]
In each embodiment, the case where the set plate 7 is stationary and the table 2 is driven is illustrated and described. However, the table 2 is stationary and the set plate 7 is driven so that the nail holder mechanism 8 and the hammer mechanism 9 The same effect can be obtained by moving the pair in the XY direction or moving the table 2 in the X direction and moving the pair of the nail holder mechanism 8 and the hammer mechanism 9 in the Y direction.
[0022]
Furthermore, it can be used as a windmill mounting machine by changing the shape of the nail supply unit 10 and the holder arm 8a.
