Is moved onto the pallet receiving member 71 via the pallet connecting portion 64. Thereafter, the stocker 40 is moved to the rising end by the lifting device 48. At this time, the left and right edge portions of the pallet P pass between the front end portions of the left and right pallet receiving members 72 retracted to the retracted end by the actuator 73. When the stocker 40 moves to the rising end, the pallet receiving member 72 is advanced by the actuator 73, and the three protrusions of the pallet receiving member 72 enter below the left and right edges of the pallet P. When the stocker 40 is lowered in this state, the pallet P is held by the three protrusions of the pallet receiving member 72 and detached from the pallet receiving member 71. The pallet P on which the empty tray Th is placed is taken out of the housing 30 by opening the open / close door 31 a provided at the upper end of the cover 31 so as to be openable and closable.

A plurality of two-dimensional displacement sensors 78 are arranged in a row direction perpendicular to the direction in which the pallet P is taken into the housing 30 by the supply tray supply device 51, and are arranged in a plurality of cavities C arranged in the supply tray Ta in the horizontal direction. The presence or absence of Q can be detected at a time.

  Reference numeral 80 denotes a control device connected to the two-dimensional displacement sensor 78. When the pallet P on which the supply tray Ta is placed is taken into the housing 30 by the supply tray supply device 51 of the take-in device 50, each of the supply trays Ta is provided. The back position of the part Q accommodated in the cavity C is detected by the two-dimensional displacement sensor 78, and the presence / absence of the part Q in each cavity C is detected and stored based on the detection signal from the two-dimensional displacement sensor 78.

  Next, the operation of the tray component supply apparatus 20 configured as described above will be described. When the tray component supply device 20 receives information on the component Q to be mounted from the electronic component mounting device 10, the stocker 40 is moved by the lifting device 48, and the pallet on which the tray T for storing the component Q to be mounted is placed. Guide grooves 41 a and 42 a holding P are aligned with the belt conveyor 62. The belt 63 is rotated by the motor 63, and the pallet P that engages with the pallet connecting portion 64 is drawn from the stocker 40 to the pallet supply position 66.

That is, the controller 80 extends from the plurality of two-dimensional displacement sensors 78 fixed above the intake port 58 to the row of cavity C portions facing the two-dimensional displacement sensors 78 of the cavity C arranged in a grid pattern. The measurement distance a is measured by a plurality of two-dimensional displacement sensors 78 for each row (step S1). As shown in FIG. 8, the measurement distance a to the cavity C is the distance to the back of the component when the component Q is accommodated in the tray T, and the cavity C when the component Q is not accommodated in the tray T. It is the distance to the bottom of the. From the dimension of the tray T, the dimension of the component Q to be accommodated, etc., the back position of the component Q when the component Q is accommodated in the cavity C, that is, the distance b from each two-dimensional displacement sensor 78 to the back position of each component Q , And the distance d from each two-dimensional displacement sensor 78 when the part Q is not accommodated to the bottom of each cavity C in the opposite row is calculated (step S2). If the measurement distance a to each cavity C portion measured by each two-dimensional displacement sensor 78 is within the allowable value α with respect to the distance b to the back position of each component Q (step S3), the cavity C If the measured distance a exceeds the range of the allowable value α, it is determined whether or not the measurement distance a is smaller than the difference (b−α) between the distance b and the allowable value α (step S5). . If it is smaller, it is determined that the part Q is housed in the cavity C in an abnormal posture, and an abnormal signal is transmitted (step S6). If it is larger, it is determined whether or not the measurement distance a is within the allowable value β with respect to the distance d to the bottom of each cavity C (step S7). If it is within the allowable value β, it is determined that there is no part Q in the cavity C (step S8). If the allowable value β is exceeded, an abnormal signal is transmitted (step S9). As described above, the control device 80 detects the presence / absence of the component Q for each cavity C arranged in a grid pattern based on the detection signals from the plurality of two-dimensional displacement sensors 78 and stores it in the storage device.
