Further, according to the width of the accommodation space 17, that is, the width of the shutter 19, the shutter 19 can be supported and opened and closed using only the driving device 21.

  The arm 33 that supports the shutter 19 includes an arm main body 34 and an arm plate 35. The arm body 34 has a shaft fixing portion 34a fixed to the drive shaft 32, a shutter fixing portion 34c to which the shutter 19 is fixed, and a connecting portion 34b for connecting the shaft fixing portion 34a and the shutter fixing portion 34c. ing. That is, the shaft fixing portion 34a and the shutter fixing portion 34c are separated. For this reason, compared with the arm member in which the shaft fixing portion and the shutter fixing portion are continuously formed, interference when rotating is difficult.

  For example, in the component shelf 10 shown in FIG. 1, the lid opening / closing device 20 disposed on the front surface of the uppermost accommodation space 17 can rotate the shutter 19 by 180 degrees or more from a position where the component outlet 17a is blocked. it can. That is, the angle range in which the shutter 19 can rotate is expanded. For this reason, even if an operator approaches the parts shelf 10, it does not interfere with the shutter 19, that is, the shutter 19 does not interfere with the work. For this reason, picking of parts becomes easy.

  The drive mechanism 70 includes a first support member 71 and a second support member 72. The first support member 71 and the second support member 72 are fixed to each other, and the motor fixing portion 71b and the bearing fixing portion 72b are arranged to face each other. Between the motor fixing portion 71b and the bearing fixing portion 72b, a sleeve 75 that engages with a flange portion 32d formed at the base end of the driving shaft 32 to restrict axial movement of the driving shaft 32, and the driving shaft Light shielding plates 76 and 77 for detecting the 32 rotational positions are provided. A motor 73 is fixed to the motor fixing portion 71b, and a motor shaft 74 fixed to the output shaft 73c is inserted into a recess formed at the base end of the drive shaft 32.

  For example, when the motor fixing portion 71b and the bearing fixing portion 72b are formed by bending one plate material, a space for fitting each member is required, and therefore, between the motor fixing portion 71b and the bearing fixing portion 72b. Is longer than that of the present embodiment. For this reason, compared with the case where one board | plate material is used, the magnitude | size of the axial direction of the drive shaft 32 of the drive mechanism 70 of this embodiment becomes small. That is, the apparatus main body 31 can be reduced in size.

Here, a method for assembling the drive mechanism 70 of the present embodiment will be described.
First, the motor 73 is fixed to one surface (left surface in FIG. 7A) of the motor fixing portion 71b with a screw inserted into the screw insertion hole 71f of the motor fixing portion 71b.

Next, the motor shaft 74 is fixed to the output shaft 73 c of the motor 73.
Next, the sleeve 75 inserted through the drive shaft 32 is screwed into the screw hole 71g of the motor fixing portion 71b and fixed to the other surface (the right surface in FIG. 7A) of the motor fixing portion 71b.

Then, the light shielding plates 76 and 77 are attached to the drive shaft 32.
Next, the second support member 72 is fixed to the first support member 71. Then, the bearing 78 is fixed to the bearing fixing portion 72 b of the second support member 72 with a fixing screw 79.

  In this assembling method, each component and screw can be attached from the right side and the upper side in FIG. Further, there is no need to change the members assembled so far during assembly. Therefore, the drive mechanism 70 can be easily assembled and the time required for the assembly is shortened.

As described above, according to the present embodiment, the following effects can be obtained.
(1) The parts shelf 10 has a plurality of storage spaces 17. The front surface of each storage space 17 is a component outlet 17a. A lid opening / closing device 20 is attached to the frame 12 above the component outlet 17a. The lid opening / closing device 20 includes a driving device 21 and an auxiliary device 22. The drive device 21 and the auxiliary device 22 are attached to the frame 12 by frame attachments 41 and 61. The driving device 21 and the auxiliary device 22 have arms 33 and 53, and the arms 19 support the shutter 19. The drive device 21 has a motor 73. The driving device 21 rotates the arm 33 by a motor 73 to open and close the shutter 19. The arm 53 of the auxiliary device 22 supports the shutter 19 and is rotated following the drive device 21.

  As described above, the lid opening / closing device 20 that opens and closes the shutter 19 includes the driving device 21 and the auxiliary device 22 that are respectively attached to the frame 12. The attachment positions of the driving device 21 and the auxiliary device 22 are set by frame attachments 41 and 61. For this reason, by adjusting the attachment positions of the driving device 21 and the auxiliary device 22, it is possible to easily cope with the shutters 19 having various shapes.

  For example, when the drive device is provided with a pair of arms to open and close the shutter, it can be attached only to the center of the shutter. On the other hand, in the present embodiment, since the driving device and the auxiliary device are separate, each can be attached to an arbitrary position, for example, both ends of the shutter.

  (2) The shutter 19 is formed in a rectangular plate shape. The arm 33 of the drive device 21 is fixed to the end of the shutter 19 (the right end in the left-right direction). The driving device 21 has a lever switch 39. Therefore, by fixing the arm 33 to the end portion of the shutter 19, when the shutter 19 is opened, the part taken out from the accommodation space 17 is unlikely to interfere with the lever switch 39, and the part can be easily taken out.

Is formed. The upper part of the clamp piece 41b is formed in an arc shape and is formed along the outer periphery of the frame 12 together with the upper part of the base 41a.

  By tightening the fixing screw 42, the base 41 a and the clamp piece 41 b clamp the frame 12, and the apparatus main body 31 is fixed to the frame 12. By loosening the fixing screw 42, the frame attachment 41 and the apparatus main body 31 to which the frame attachment 41 is attached can be moved along the frame 12. The fixing screw 42 is inserted into the screw insertion hole of the base 41a and is screwed into the screw hole of the clamp piece 41b disposed on the rear side of the base 41a. Therefore, the apparatus main body 31 can be fixed and the position can be set by work from the front side of the apparatus main body 31.

  (4) The support shaft 52 of the auxiliary device 22 is arranged coaxially with the drive shaft 32. For this reason, the shutter 19 can be held by the arm 53 having the same shape as the arm 33 of the driving device 21, and the shutter 19 can be rotated on the same axis.

In addition, you may implement the said embodiment in the following aspects.
In contrast to the present embodiment, the shutter 19 may be changed as appropriate, such as a sheet-like member.
