Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment 1：

As shown in figure 1, a kind of detect that being provided with multiple confession articles in pallet, including tray body 1, tray body 1 places Accommodating chamber 11, in Fig. 1, accommodating chamber 11 is provided with 3.It is provided with to detect that article has on the side wall of each accommodating chamber 11 The optoelectronic switch 2 of nothing.

Optoelectronic switch 2 includes transmitter 21 and receiver 22.As shown in Fig. 2 transmitter 21 is just to receiver 22, article is put It is placed in one to both and occurs barrier.The bottom of accommodating chamber 11 is provided with the button switch AN1 to be triggered according to article gravity, Button switch AN1 includes pressure part 41 and is arranged in the spring 42 of the bottom of pressure part 41, tray body 1 to be provided with to limit Pressure part 41 processed moves down the limited block 43 of stroke.Load-bearing effectively can be carried out to article, then, by limited block 43 to pressure part 41 progress are effectively spacing, while the elastic ability to bear of spring 42 can be protected, it is to avoid spring 42 occurs exceeding recoverable shape Variable.
