  The control means that has received the selection signal operates the operation mechanism 14 of the carry-out means 8 based on the selection signal, moves the carry-out holding hand units 13a, 13b, and 13c onto the selected measuring unit 5, The carrying-out holding hand units 13a, 13b, and 13c are lowered at the position, and the measurement object A is gripped by the hands 32a and 32b.

  Then, the holding hand units for unloading 13a, 13b, and 13c are lifted while holding the measurement object A, and in this state, the holding hand units for unloading 13a, 13b, and 13c are refilled along the unloading rail 11 into the refill chamber 4. The holding hand units 13a, 13b, 13c for unloading are moved down to the position on the temporary placement table 15, and the objects to be measured are placed on the temporary placement tray on the temporary placement table 15 by the hands 32a, 32b. Place and complete transfer.

  On the other hand, the replenishing means 9 performs the replenishment work to the empty measurement unit 5 simultaneously with the carry-out work of the objects A, A.

  First, as shown in FIG. 8A, the control means moves the rearrangement trays 40a, 40b, 40c to the rearrangement mechanism 41 so that they are arranged in a slightly shifted arrangement in the direction between the measurement unit rows (the origin). return).

  At this position, new measurement objects A, A... Supplied by the supply conveyor 43 are placed on the rearrangement trays 40a, 40b, 40c using the transfer mechanism 44.

  In this operation, first, the stopper cylinders 83, 83... Are operated, and the supply trays 82, 82... Flowing on the supply conveyor 43 are placed in a predetermined stop position, that is, each rearrangement tray at the origin position. 40a, 40b, and 40c are stopped at positions aligned in the direction between the measurement unit rows.

  Next, the transfer slide unit 88 of the transfer mechanism 44 is operated to move the transfer holding hand unit 87 over the supply trays 82, 82... At the stop position, and change holding at that position. The hand unit 87 is lowered and the measured object A is held by the hands 103, 103.

  Then, the transfer holding hand unit 87 is raised and the transfer slide unit 88 is operated to move the transfer holding hand unit 87 onto the rearrangement trays 40a, 40b, 40c, and FIG. 14 (b). As shown in FIG. 15B, the rotating unit 108 is operated to rotate the hands 103, 103... By 90 degrees, and the directions of the measured objects A, A ... are rearranged trays 40a, 40b,. Match the direction of 40c.

  In this state, the transfer holding hand unit 87 is lowered and the claws 104, 104 of the hands 103, 103 ... are opened, and the objects A, A ... are placed on the rearrangement trays 40a, 40b, 40c. After that, the transfer holding hand unit 87 is raised. This operation is repeated in synchronization with the operations of the carry-out means 8, the rearrangement mechanism 41, and the transfer mechanism 42.

  On the other hand, when the objects to be measured A, A,... Are replenished to the rearrangement trays 40a, 40b, 40c at the origin position, the control means then operates the rearrangement mechanism 41 to move the rearrangement trays 40a, 40b, 40c. 40a, 40b, and 40c are rearranged.

  The rearrangement by the rearrangement mechanism 41 is performed by a combination of operations of the rearrangement slide units 47a, 47b, 47c and the extrusion units 50b, 50c. In addition, the example of a rearrangement pattern is shown to FIG. 16, FIG. 17, and the position of the selected measurement part on the combination scale 2 is specified by a blank part.

  For example, as shown in FIGS. 16 (a) and 16 (b), when three objects to be measured are selected with a bias toward either one of the measurement unit rows a and b, only the rearrangement slide units 47a, 47b and 47c are selected. Each of the rearrangement trays 40a, 40b, and 40c is moved so as to be aligned in a line on the upstream extension line of one of the measurement unit rows a and b, and the two trays 40a, 40b, and 40c are moved as shown in FIG. When the measurement object is selected from the measurement unit row a and one measurement object is selected from the measurement unit row b, the rearrangement trays 40a and 40c are arranged on the measurement unit row a side in the rearrangement slide units 47a and 47c. The rearrangement tray 40b is moved to the measurement unit row b side to the intermediate rearrangement slide unit 47b.

  On the other hand, when objects to be measured arranged in the direction between the measurement unit rows a and b are selected as shown in FIG. 16C, the rearrangement supported by the rearrangement slide unit 47a on the measurement means side is selected. The tray 40a is moved to the measurement unit row b side, the other rearrangement trays 40b and 40c are moved to the measurement unit row a side, and the extrusion units 50b and 50c are operated to move the rearrangement tray 40b to the rearrangement tray 40a. The rearrangement tray 40c is moved to the position aligned in the direction between the measurement unit rows and the rearrangement tray 40b at the origin position.

  When the rearrangement by the rearrangement mechanism 41 is completed in this way, the measurement object A, A...

  First, the control means synchronizes the movement of the transfer mechanism 44 to the conveyor side and the operation of the rearrangement mechanism 41, and moves each transfer hand unit 62 a, 62 b, 62 c to the front end of the transfer rail 60 on the front side of the work line. The transfer holding hand units 62a, 62b, and 62c are moved onto the rearrangement trays 40a, 40b, and 40c that have been rearranged.

  At that position, the holding hand units 62a, 62b, 62c for transfer are lowered, and only the hand 79 at the position corresponding to the rearrangement trays 40a, 40b, 40c is operated based on the selection signal, and the measured objects A, A. Gripping ..

  For example, as shown in FIG. 16C, when the objects to be measured arranged in the direction between the measurement unit rows a and b are selected, the operations of the hands 79a and 79b are based on the selection signal. Both hands 79a and 79b of the transfer holding hand unit 62c on the upstream side in the direction are not operated, and in the intermediate transfer holding hand unit 62b, only the hand 79a on the conveyor side is operated to close the claw portions 80 and 80, and the downstream In the transfer holding hand unit 62a on the side, both hands 79a and 79b are operated to close the claw portions 80 and 80. In addition, the other hand 79 which is not operated is left in a state where the claw portions 80 are kept open.

  On the other hand, when the selected objects to be measured do not overlap in the direction between the measurement unit rows a and b as shown in FIGS. 13 (g) and 13 (h), each of the transfer holding hand units 62a, 62b, and 62c is one of them. The object to be measured is gripped by operating only the hand.

  Then, the control means raises each transfer holding hand unit 62a, 62b, 62c in a state where the objects to be measured A, A ... are gripped, and operates the transfer slide units 63a, 63b, 63c, The transfer holding hand units 62a, 62b, and 62c are slid to the corresponding positions of the empty measurement units 5, 5.

  Then, at each position, the transfer holding hand units 62a, 62b, 62c are lowered, and the claws 80, 80 of the closed hands 79a, 79b are opened, whereby a new object to be measured is replenished to the empty measuring unit 5. The
