The overall operation of the crushing device 1 including the operation of the control unit 1B will be briefly described below. The operator turns on the power switch 26 after confirming the working pressure of an air source and an air pressure adjusting regulator (not shown). After turning on the power switch 26, the operator sets the following conditions in accordance with the type of the sample 2 to be crushed before operating the crusher 1. (1) Selection of manual operation or automatic operation (2) Setting of upper limit stop time and lower limit stop time of percussion cylinder 7 (3) Torque setting of drive motor 13 (4) Work time setting (5) Return to origin (The origin is arbitrarily determined depending on the operation of the striking means, but in this case, the origin is the position when the striking means 6 is at the rear limit position and the left limit position.) Each of the above After inputting the conditions (or before inputting), the operator sets the packed sample 2 in the fixed frame 5 provided on the support base 3 and confirms that there is no foreign matter on the striking surface. The starting switch 27 is turned on to activate the crushing mechanism 1A.

(Regarding Automatic Operation) When the start switch 27 is input, the striking air cylinder 7 is driven and the hammer head 9 moves up and down to start crushing the sample 2 located below. At this time, at the same time, the drive motor 13 rotates to advance the striking means 6 together with the guide plate 10. As a result, the striking means 6 moves forward and crushes the sample 2. When the front position sensing means 21 senses the front limit position of the guide plate 10 (that is, the striking means 6), the control unit 1B stops the rotation of the drive motor 13 and moves the left-right moving air cylinder 17 to the right ( That is, it is driven to the pull-in side. As a result, the striking means 6 moves to the right and further crushes the sample 2. When the left / right position sensing means senses the right limit position of the left / right moving air cylinder 17 (that is, the striking means 6), the controller 1A stops the left / right moving air cylinder 17 and causes the drive motor 13 to rotate in the reverse direction. The striking means 6 is retracted together with the plate 10. After that, when the rear position sensing means 22 senses the rear limit position of the guide plate 10 (that is, the striking means 6), the control unit 1B stops the reverse rotation of the drive motor 13 and causes the left-right moving air cylinder 17 to move. The striking means 6 is moved to the left by driving to the left (that is, to the pushing side). The above-mentioned movement of the hitting means 6 is continuously continued until the set work time is reached, and when the work time elapses, it is automatically returned to the origin. As a result, during the working time, the striking means 6 automatically and uniformly grinds the sample 2 while moving forward, backward, leftward and rightward as shown in FIG.

(About Manual Operation) In the case of manual operation, when the start switch 27 is input, the impact air cylinder 7 is driven and the hammer head 9 moves up and down to crush the sample 2. In this embodiment, in this case, the striking means 6 does not move from the origin, and the sample 2 is crushed at that position. Regardless of automatic operation or manual operation, the control unit 1B automatically adjusts the striking pressure of the striking means 6 on the basis of the detection signal from the pressure sensing means, even if there is a thin portion or a thick portion of the sample. , The sample is evenly crushed to evenly crush the sample.

(Regarding Another Embodiment) In the present embodiment described above, the hammer head 9 is fixed to the piston 8 of the striking air cylinder 7, but this is not limited to this embodiment. The hammer head 9 may be attached to the piston 8 so as to be rotatable around the axis of the striking air cylinder 7. By rotatably mounting the hammer head 9 in this manner, for example, when crushing a sample long in the lateral direction, the hammer head 9 is rotated 90 degrees from the state shown in the present embodiment, and the length of the sample 2 is increased. There is an effect that it becomes possible to cope with the crushing of a wider range of samples, such as proceeding the crushing work along the direction. Further, in the present embodiment, the front and rear position sensing means 21, 22 and the left and right position sensing means 23 are fixed to the fixed frame 2 and the guide plate 10, but the configuration of these sensing means is not limited to this embodiment. The front-rear direction detecting means 21 and 22 can be moved back and forth, and the left-right direction detecting means 23 can be moved left and right. By thus configuring the position of each sensing means as necessary, for example, when the sample to be crushed is small, the moving range of the striking means is narrowed, and the sample to be crushed is When it is large, the movement range of the striking means can be arbitrarily changed, for example, the movement range of the striking means can be widened, and the crushing work can be performed more efficiently. Further, in the present embodiment, the crushing time is set according to the working time, but this is not limited to this embodiment, and for example, the crushing time is set by setting the number of hits. Good. Further, in the present embodiment, the crushing is performed in a state where the striking means is stopped at the origin during the manual operation, but this is not limited to the present embodiment, and for example, the drive motor 13 only The operation switch for the left and right moving air cylinders 17 is provided, and the operator operates these switches as needed while observing the crushing condition of the sample 2 during the crushing work by the striking means. Then, the striking means 6 may be configured to be movable back and forth and left and right. Further, in the present embodiment, the striking means is configured to be moved forward, backward, leftward, and rightward by the control device, but the movement pattern of the striking means is not limited to that in the present embodiment, and the striking means can be moved forward, backward, leftward, rightward, or leftward. A movement pattern that moves diagonally may be used by combining the movements of.
