-VI arrow view, FIG. 59 is a IX-IX arrow view of FIG. 55.
Further, FIG. 60 is a perspective view of the state where the shielding mechanism 310 is opened, and FIG. 61 is a view taken in the direction of arrow II in FIG. As shown in FIGS. 60 and 61, the shielding mechanism 310 includes a pair of first shielding plates 31 for covering the upper side and the upper side of the component box 2.
1, a second shielding plate 312 and a third shielding plate 313 for covering the upper rear surface of the component box 2 are provided, and the ends of the respective shielding plates 311, 312, 313 are connected to each other by a hinge 314. It is designed so that it can be folded.

The hinge 3 is attached to the first shield plate 311.
Short pin 3 at the lower end of the side opposite to the side where 14 is fixed
11m (see FIG. 56) is fixed, and the long pin 311n is fixed to the upper end of the side coaxially with the short pin 311m. The short pin 311m is inserted in a through hole 310k formed in the lower frame 310d, and the long pin 311n is inserted in a through hole 310h formed in the upper frame 310u. With this structure, the left and right first shield plates 311 can rotate about the axes of the short pins 311m and the long pins 311n.
Further, a pulley 311p is fixed to the upper end of the long pin 311n of each first shielding plate 311, and a ring-shaped drive wire 311w is twisted once on both pulleys 311p. Here, the pulley 311p and the drive wire 311w are connected to the block 3 as shown in FIG.
It is connected at the position 11b so that no slippage occurs between the pulley 311p and the drive wire 311w. Further, the drive wire 311w has a pulley 31
An arm 311a is fixed in the middle of 1p,
The piston rod of the cylinder 311y is connected to the arm 311a.

With this structure, when the cylinder 311y is actuated in the direction in which the piston rod is extended, as shown in FIG.
In, the left pulley 311p rotates clockwise and the right pulley 311p rotates counterclockwise by the same angle.
When the cylinder 311y is actuated in the direction for accommodating the piston rod, the left pulley 311p rotates counterclockwise and the right pulley 311p rotates clockwise by the same angle. As a result, the left and right first shield plates 31 connected to the respective pulleys 311p via the long pins 311n.
1 rotates around the axis of the long pin 311n or the like in opposite directions to open and close like a door. Here, the diameter of the pulley 311p and the stroke of the cylinder 311y are set to values such that the left and right pulleys 311p can rotate about 90 °. Further, the connecting position (position of the block 311b) between the pulley 311p and the drive wire 311w is
It is adjusted so that the left and right first shield plates 311 are closed substantially parallel to the W axis in a state where the cylinder 311y extends the piston rod. Further, as shown in FIG. 55, the upper frame 310u supporting the long pins 311n of the first shielding plate 311 has a slit 310 in the center in the L-axis direction as shown in FIG.
s is formed, and a center pin 313p provided at the center of the upper end of the third shielding plate 313 is formed in the slit 310s.
Has been inserted. As a result, the center of the third shield plate can move along the slit 310s.

With this structure, when the first shielding plate 311 is closed substantially parallel to the W axis, that is, when the shielding mechanism 310 is folded as shown in FIG. 55, the cylinder 311y is moved to the piston rod. When operated in the direction to store the
Rotated, the first shield plate 311 on the right side rotates about clockwise in the figure.
It is rotated 90 °. As a result, the left and right first shield plates 31
1 is opened like a door, these first shielding plate 311 and hinge 3
The second shield plate 312 connected by 14 is rotated by the first shield plate 311 to a position substantially parallel to the L axis while being pressed by the first shield plate 311. Further, as the second shield plate 312 rotates, the third shield plate 313 moves in the L-axis direction while being pushed by the second shield plate 312. Here, as described above, the central pin 313p of the third shielding plate 313 is not connected to the upper frame 31.
Since the third shield plate 313 does not shift in the width direction (W axis direction) because it moves following the 0 u slit 310s, the left and right second shield plates 312 rotate at substantially equal angles. As a result, the shielding mechanism 310 operates in the manner shown in FIGS.
As shown in, it is spread out in a square shape. Further, by operating the cylinder 311y from this state in the direction of extending the piston rod, the first shielding plate 311, the second shielding plate 312, and the third shielding plate 313 are moved in the opposite direction to the above, As shown in FIG. 55 and the like, the shielding mechanism 3
10 is folded.

A device box take-out device 30 according to this embodiment.
When the desired component is taken out by 0, first, the device 300 is operated with the shielding mechanism 310 folded, and the predetermined component box 2 is transferred from the stock section or the like (not shown) to the component supply shelf 370. Supplied. Here, the procedure for supplying the component box 2 to the component supply shelf 370 is the same as in the case of the first embodiment. Then, after the component box 2 is supplied to the component supply shelf 370, the cylinder 311y is operated and the shielding mechanism 310 is expanded in a square shape. As a result, the upper space of the component box 2 is covered from the surroundings by the first shielding plate 311, the second shielding plate 312, and the third shielding plate 313, and the upper space of the component box 2 is divided into the first rail, the second rail, and the bracket ( It is separated from the operating space (not shown).
As a result, the worker can safely take out the parts from the parts box 2 even when the parts box take-out device 300 is in operation. Further, the shielding mechanism 310
Does not require a large installation space because it can be folded.
