Claims (1)

[Scope of claim for utility model registration] (1) A first magazine that stores trays loaded with workpieces in a grid pattern, a second magazine that stores empty trays after all the workpieces have been extracted, and a tray. a guide member for guiding the trays from the first magazine to the second magazine; a carrying-out means for carrying out each tray from the first magazine to the starting end of the guiding member; A conveyance means that intermittently conveys in the X-axis direction, a conveyance means that conveys each tray from the end of the guide member to the second magazine, and a conveyance means that moves in the Y-axis and Z-axis directions and stops each tray during intermittent conveyance. A tray loader comprising a supply means for sequentially extracting each workpiece on a predetermined workpiece row in a tray and supplying it to a predetermined location. (2) The conveying means includes a driven shaft supported by a frame so as to be movable in the Z-axis direction, a main cam mechanism that provides intermittent Z-axis reciprocating motion to the driven shaft, and
a conveyance beam supported by a driven shaft so as to be movable in the axial direction; and a lever pivotally connected to the frame so as to be swingable within a plane containing the conveyance beam and slidably intersect with the conveyance beam at a predetermined position. ,
Gives the lever a swinging motion synchronized with the main cam mechanism,
A sub-cam mechanism configured to give the transport beam forward and backward motion in the X-axis direction at its upper limit position and lower limit position, respectively, a coupling mechanism that connects the transport beam and the tray at the upper limit position of the transport beam, and a supply means. 2. The tray loader according to claim 1, further comprising a sensor that detects the completion of extraction of the last workpiece on a predetermined row of workpieces in the tray and provides a signal to the main cam mechanism and the subcam mechanism to start the next conveyance operation. . (3) The conveying means includes a driven shaft supported by the frame so as to be movable in the Z-axis direction, a tray stand fixed to the driven shaft, and an intermittent Z-axis reciprocating motion to the driven shaft, and a second A cam mechanism that takes two positions: an upper limit position that reaches the lowest tray inside the first magazine and a lower limit position that is at the same height as the guide member, and a cam mechanism that moves the tray in the first magazine to the tray stand at the upper limit position of the tray stand. 2. The tray loader according to claim 1, comprising a transfer mechanism and a sensor for detecting the position of the tray on the tray base and guide member and providing a signal to the cam mechanism to initiate the next tray unloading operation. (4) The carrying means includes a driven shaft supported by the frame so as to be movable in the Z-axis direction, a tray stand fixed to the driven shaft, and an intermittent Z-axis reciprocating motion to the driven shaft, and a second movement to the tray stand. 2. A cam mechanism that allows the toilet to take two positions, an upper limit position reaching the lowest tray inside the magazine and a lower limit position at the same height as the guide member, and a cam mechanism that moves the toilet received from the guide member onto the tray stand at the upper limit position of the tray stand. 2. The tray according to claim 1, comprising a transfer mechanism for transferring the tray to the second magazine, and a sensor for detecting the position of the tray on the tray stand and the guide member and providing a signal to the cam mechanism to start the next tray carrying operation. loader.
