The embodiment of the utility model provides a detection mechanism and a meal distribution machine, and as shown in figure 1, the detection mechanism comprises: the lunch box comprises a lunch box frame 1, two support tables 2 and a detection device, wherein a lunch box 3 is arranged on the lunch box frame 1, the lunch box frame 1 comprises a guide groove 11, a left wing 12, a right wing 13 and a support passage 14 (shown in figure 3), wherein the guide groove 11 is arranged in a gap between the two support tables, and the left wing 12 and the right wing 13 are detachably erected on the table surfaces of the two support tables and are fixed by screws; the bracket passage 14 is arranged at the near tail end of the guide groove 11 and is opened downwards; the lunch box 3 moves to a required position along with a conveyer belt, a conveyer rail or other conveyer devices on the guide groove, and the detection device is fixed above an external detection mechanism or on the lunch box frame 1 at the tail end of the guide groove 11.

Specifically, the width of cutlery box 3 slightly is less than the width of guide slot 11, and the clearance width between two brace tables 2 is slightly bigger than the width of guide slot, and left wing 12 and right wing 13 of cutlery box frame 1 fix on two brace table 2 mesas, guarantee the stability of cutlery box 3 on cutlery box frame 1. Specifically, the opening of the holder passage 14 is not larger (smaller than or equal to) the width of the guide groove.

In the embodiment of the application, in order to judge the in-place situation of the lunch box, the detection device comprises the following three embodiments: fig. 1 to 3 show an example of a first mode; FIGS. 4 and 5 illustrate a second embodiment; fig. 6 to 8 show a third embodiment.

In the embodiment shown in fig. 1-3, the detection device provided in this embodiment is an optoelectronic switch device 4, and the detection mode is diffuse reflection. The photoelectric switch device 4 comprises a photoelectric switch 41 and a switch bracket 42, wherein the photoelectric switch 41 is fixed above the lunch box frame by the switch bracket 42 and is used for irradiating the lunch box 3 and judging whether the lunch box 3 is in place. The photoelectric switch 41 has the advantages of small volume, multiple functions, long service life, high precision, high response speed, long detection distance and strong light, electricity and magnetic interference resistance, and the detection efficiency is greatly improved by using the mode for detection.

Specifically, the light emitted from the diffuse reflection type photoelectric switch needs to be reflected back to the receiver of the diffuse reflection switch by the surface of the object to be detected, so the detection distance and the surface reflectivity of the object to be detected determine the intensity of the light received by the receiver, and the material of the bracket channel and the material of the lunch box should be avoided from meeting certain reflection parameter requirements. Therefore, the present embodiment does not limit the setting position and the light emitting angle of the photoelectric switch, and should be adjusted accordingly according to the actual situation.

The diffuse reflection type photoelectric switch 41 is a sensor integrating a transmitter and a receiver, when the meal box 3 moves to the end of the guide groove, as shown in fig. 1, the meal box 3 reflects a sufficient amount of light emitted by the transmitter of the photoelectric switch 41 to the receiver, and then the photoelectric switch 41 generates a switching signal, i.e. determines that the meal box is in place. When the lunch box 3 is removed, as shown in fig. 2, the light emitted from the photoelectric switch 41 irradiates the bracket passage 14, and the photoelectric switch 41 cannot receive the reflected signal, so as to determine that the lunch box rack has no lunch box or the lunch box is not in place.

Fig. 4-6 show a second embodiment of the detection mechanism and the meal-dispensing machine according to the embodiment of the utility model, which provides a detection device in the form of a proximity switch device 5 mounted in the vertical direction at the end of the guide slot of the frame of the meal box. The proximity switch type device 5 comprises a swing detection piece 51, a swing piece bracket 52 and a proximity switch 53, wherein the swing detection piece 51 is arranged at the horizontal center line of the swing piece bracket 52, one end of the swing detection piece is connected to the swing piece bracket 52 in a swing mode, the other end of the swing detection piece is in an off state, and the proximity switch is correspondingly arranged at the other side of the center line of the swing piece bracket 52 and penetrates through the swing piece bracket 52; the rotation range of the swing detection piece 51 touches the proximity switch 53, and the specific structure can be referred to fig. 5. The proximity switch is used as a switch type sensor (namely a non-contact switch), has the characteristics of a travel switch, has sensing performance, and has the characteristics of reliable action, stable performance, fast frequency response, long service life, strong anti-interference capability, water resistance, shock resistance, corrosion resistance and the like.

Specifically, the principle of the proximity switch of the present embodiment is similar to that of the magnetic switch, and the structural arrangement is common. In other embodiments, magnetic switches may be used.

The proximity switch 53 is a position switch that can be operated without mechanically directly contacting a moving member, and when the sensing surface of the object proximity switch 53 reaches an operating distance, the switch can be operated without mechanically contacting and applying any pressure. In this embodiment, as shown in fig. 4, when the lunch box 3 is pushed forward to the end along the guide slot 11 of the box frame 1, the edge of the lunch box 3 touches the swing detection piece 51, the swing detection piece 51 can swing along the swing shaft, the swing detection piece 51 approaches the proximity switch during the swing process, the proximity switch 53 is turned on by magnetic force induction, and the lunch box is determined to be in place. When the lunch box 3 is taken away, as shown in fig. 6, the swing detection piece 51 is far away from the proximity switch 53 under the action of gravity or spring force (not shown), and the proximity switch 53 is turned off, so that it can be determined that no lunch box or the lunch box is not in place.

Fig. 7-8 show a third embodiment of the detection mechanism and the meal-dispensing machine according to the embodiment of the utility model, which provides a detection device in the form of a microswitch-type device 6, also mounted in the vertical direction at the end of the guide slot 11 of the frame of the meal box. The microswitch-type device 6 comprises a rocker 61, a microswitch 62 and a microswitch bracket 63. The swing rod 61 is arranged in a vertical plate at the tail end of the guide groove 11, and the micro-switch support 63 is arranged outside the vertical plate. The micro switch has the advantages of micro contact interval, short action stroke, small pressing power, quick on-off and the like, and greatly improves the detection efficiency.

In this embodiment, the lunch box 3 is pushed forward along the guide slot 11 of the lunch box frame 1, as shown in fig. 7, the edge of the lunch box 3 touches the swing link 61 of the micro switch device 6 and continues to be pushed forward, and the swing link 61 presses down the micro switch 62 of the detection device by the force effect, so that the micro switch 62 is turned on, and it can be determined that the lunch box is in place. When the lunch box 3 in the guide groove 11 is taken away, the swing rod 61 automatically resets under the self elastic action, and the micro switch 62 is switched off at the moment, so that the lunch box is judged to be not in place.

Therefore, the detection mechanism and the meal distribution machine adopting the detection mechanism provided by the embodiment of the utility model can solve the problem of in-place detection of the meal boxes during automatic meal distribution, improve the efficiency and avoid dirt and waste caused by wrong distribution.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
