It is configured to be movable between a retracted position (not shown).

Next, operation | movement of the apparatus 20 which cuts the rod lens array original plate of this embodiment is demonstrated.
First, a plurality of rod lens array original plates 1 are accommodated side by side in an upright state so that the rod lens array 2 extends in the horizontal direction in the receiving portion 32 of the original plate accommodating portion 22. A cylindrical member 43 made of metal is arranged on the rear side of the plurality of rod lens array original plates 1 arranged in the above. Next, the vibration device 42 is operated to vibrate the receiving portion 32 in small increments.

  The plurality of rod lens array original plates 1 housed in a standing state in the receiving portion 32 slides down on the rail 34 in the A direction due to the vibration by the vibration device 42, the inclination of the receiving portion, and the columnar member 43. It is surely gathered on the 24 side. A sensor (not shown) for detecting that the leading rod lens array original plate 1 has reached one end (lower end) of the receiving portion 32 is provided at one end (lower end) portion of the receiving portion 32, It is detected that the leading rod lens array original plate 1 has reached one end (lower end) of the receiving portion 32.

In this state, by the air cylinder 44 of the transfer mechanism 26, the protrusion plate 46 of the transfer mechanism 26 is in the lower (retracted) position to the upper (protrusion) position where the leading rod lens array original plate 1 is located. And raise.
When the projecting plate 46 moves upward from the lower position toward the upper position, the push-up plate 46 in which the leading rod lens array original plate 1 at the head of the plurality of rod lens array original plates 1 accommodated in the receiving portion 32 has moved upward. Is pushed upward and obliquely upward from below, and is pushed outward from the receiving portion 32.

  Then, the extruded rod lens array original plate 1 falls toward the stage 24 while rotating as indicated by the arrow B so that the upper end draws a locus indicated by a dotted line in FIG. 9 is transferred onto the stage 24 which is arranged in the receiving (rear) position shown in FIG. The rod lens array original plate 1 surely falls on the stage 24 as its tip extends along the guide wall 29.

  At this time, a portion that is bent inward of the pressing plate 38 is formed above the second to several rod lens array original plates 1 from the front of the plurality of rod lens array original plates 1 accommodated in the receiving portion 32. Therefore, only the top one is reliably pushed up and transferred to the stage 24.

  When the protruding plate 46 reaches the upper position and the leading rod lens array original plate 1 is pushed out and dropped onto the stage 24, the protruding plate 46 is lowered to the lower position by the air cylinder 44. When the protruding plate 46 is lowered from the upper position to the lower position, initially, the second rod lens array original plate 1 from the front is the leading rod lens array original plate 1 in the receiving portion 32 due to the inclination of the receiving portion 32 or the like. Slide down on the rail 34 to the position.

On the other hand, the leading rod lens array original plate 1 that has fallen on the stage 24 along the guide wall 29 is the rear end of the front surface of the stage 24 by the rear end determination block 50, and both side ends by the side end determination members 52. Is positioned at a predetermined position with respect to the stage 24. Furthermore, each claw portion 54 is loosely fitted in the groove between the adjacent rod lens arrays 2 and 2 of the rod lens array original plate 1 placed on the stage 24, so that the rod lens array original plate 1 can be obtained with higher accuracy. Is positioned relative to the stage 24.
At this time, the stage 24 is vibrated by the vibration mechanism, so that the rod lens array original plate 1 is reliably positioned by the rear end determination block 50, the side end determination member 52, and the claw portion 54.

  In the apparatus 20 of this embodiment, when the rod lens array original plate 20 is positioned on the stage 24, the suction device connected to the suction hole 48 is operated, and the rod lens array original plate 1 positioned on the stage 24 is operated. Is sucked and fixed to the surface of the stage 24.

  After confirming that the rod lens array original plate 1 is fixed to the surface of the stage 24 by a vacuum sensor (not shown), the moving mechanism 30 disposed below the stage 24 is operated, and the stage 24 receives (rear). From the position (FIG. 9), the feed lens (front) position (FIG. 10) where the tip of the rod lens array original plate 1 placed on the stage 24 is sandwiched between the upper and lower disk blades 58, 58 rotated by the cut forming device 28. Moved to.

  When it is detected by a sensor (not shown) that detects the tip position of the stage 24 that the stage 24 has reached the delivery position, the suction of the rod lens array original plate 1 to the stage 24 is stopped. When the stage 24 is in the delivery position, the rod lens array original plate 1 placed on the stage 24 is sandwiched between the upper and lower disk blades 58 and 58 rotating by the cut forming device 28, so that the disk blade 58 , 58 is fed between the disk blades 58, 58 while sliding on the stage 24 in the direction of arrow D.

  Since each disk blade 58 is disposed at a position corresponding to each exposed rod lens portion 4 of the rod lens array original plate 1, all the exposed rod lens portions 4 of the rod lens array original plate 1 are vertically moved by the disk blade 58. A break is formed.

The front end portion of the rod lens array original plate 1 in which a cut is formed by the disk blade 58 is supported from below by a support shaft 64 disposed on the downstream side of the rotary blade 56 (FIG. 11), thereby making a cut to the rear end portion. Until the formation is completed, the rod lens array original plate 1 is maintained in a substantially horizontal state.
At substantially the same time as the rear end of the rod lens array original plate 1 is released from the rotary blade 56, the support shaft 64 is retracted to the retracted position, and the rod lens array original plate 1 in which a cut is formed in the exposed rod lens portion 4 is stored. Drop into box 66.

  The rod lens array original plate 1 in which the cuts are formed in each exposed rod lens portion 4 is bent at the exposed rod lens portion 4 so that the rod lens material 10 is folded at the exposed rod lens portion 4 and separated into individual rod lens arrays 2. Is done. Thereafter, final finishing is performed such as polishing of the end face from which the rod lens material 10 is exposed.

According to the device for cutting the rod lens array master plate having such a configuration, it is possible to cut all exposed rod lens portions of the rod lens array master plate at the same time. Work efficiency is improved.
Further, since the upper and lower disk blades are configured to form a cut in the upper and lower sides without cutting the exposed rod lens portion 4, the advantages that the disk blades do not contact each other and the life of the blades is prolonged, and There is an advantage that there is little generation of garbage. Further, since the sheet can be discharged in the form of a cut, it is less bulky in the storage box 66, such as being easy to handle after passing through the cutting device 28, and the advantage of being easy to adjust the clearance of the blade. is there.

Further, when making a cut in the exposed rod lens portion 4, the rod lens array original plate 1 is sent by the rotation of the disk blade 58 with the disk blade 58 inserted in the groove between the adjacent rod lens arrays 2, 2. Accordingly, since the disc blade 58 enters the groove of the rod lens array original plate 1, the positioning of the rod lens array original plate 1 with respect to the disc blade 58 is automatically performed, so that a cut can be surely formed in the exposed rod lens portion. it can.
In addition, the cutting apparatus according to the above embodiment is safe because a series of processes in which the blade is used is performed without human intervention.

  Without being limited to the above-described embodiment of the present invention, various changes and modifications can be made within the scope of the technical idea described in the claims.

  In the above embodiment, the rotary blade only forms a cut in the exposed rod lens part, but the upper and lower rotary blades may be arranged so as to completely separate the exposed rod lens part.
