It is configured to rotate the one end of the axis to the axis to recover the pizza.

Various types of vending machines are used, and pizza vending machines are one of them. First, the schematic structure and operating state of the pizza vending machine will be described with reference to FIG.

As shown, FIG. 1 is a front view showing the schematic structure of the pizza vending machine 2 conventionally used, with the front cover removed. On the upper side of the vending machine 2, a freezer (freezer) 4 having a plurality of stacking boxes 6 for loading pizza therein is rotatably installed on the side wall of the vending machine, and the lower side is for heating the pizza sold. The microwave oven 14 is provided. The pizza tray 22 is fixed to the inner surface of the door 16 of the microwave oven 14 to accommodate the pizza.

Installed below the freezer 4 is a take-out mechanism 10 for selecting and dispensing pizzas. When the buyer selects the pizza, the pizza takeout disk 8 rotates to eject the pizza selected by the buyer from the plurality of stackers 6 of the freezer 4 so that the ejected pizza can be eaten by the takeout mechanism 10. In order to be heated, it is discharged to the pizza tray 22 of the microwave oven 11.

The pizza tray 22 of the microwave oven 14 is attached to the inside of the door 16 of the microwave oven, and is not movable in the vertical direction and has a separate operation rod in the tray moving hole 26 in the horizontal direction. It is fixed by the hinge so that it can be inserted and moved.

Although not shown, a rod extending from the microwave oven body is connected to an inner surface of the microwave oven door 16 to open and close the door 16. The pizza tray 22 is also integrally formed of a material which is hardly heated by electromagnetic waves generated in a microwave oven.

After the pizza is discharged into the pizza tray 22, the microwave oven door 16 is automatically closed, and the microwave oven 14 is operated by pressing the switch sw1 installed under the door 16 to generate electromagnetic waves. Let's do it. The pizza thrown into the microwave oven 14 by the carrying out mechanism 10 is blocked by the movement preventing rod 24 so that the position is fixed correctly.

However, conventionally, during the sale of the pizza, the consumer does not collect the pizza selected or the pizza detection sensor may not be detected due to a failure of the pizza detection sensor that detects the presence of the pizza through the sensor detection hole 28. It became. In this case, the control unit automatically outputs the pizza sale stop signal to stop the sale of the pizza.

Therefore, for a long time, that is, until the pizza vending machine is repaired and sold normally again, the pizza is placed in the pizza tray and the pizza vending machine is not available, which causes the sale.

In this state, the administrator of the vending machine checks from time to time to repair the problem is not a problem, but in the case of managing a large number of pizza vending machines troubleshooting was often delayed.

The present invention was devised to solve the above problems, and the object of the present invention is a pizza vending machine capable of recovering a product automatically discarding it when a pizza is loaded in a pizza tray even after a predetermined time has elapsed. To provide a tray structure.

The tray structure of the present invention for achieving the above object is attached to the inner surface of the door of the microwave oven, a pizza tray in which a rod protruding from the surface to fix the pair of walls and the pizza in place, the pizza tray Separating the tray frame and the tray pivot located in the tray frame and rotatably fixed to each other, and forming a tray projection on the bottom bottom of the tray pivot; A tray inserted into the tray protrusion and rotating the tray pivot around a rotation shaft, the tray including a first rod, a second rod connected to the first rod, and a driving motor having a rotation shaft connected to the first rod; It is characterized by consisting of the operating means.

Hereinafter, a tray structure of a pizza vending machine capable of collecting a product of the present invention will be described in detail with reference to FIGS. 2 to 4.

2 is a perspective view showing a tray structure according to the present invention. As shown, the conventional pizza tray is separated into a tray frame 22 'and a tray pivot 22-2. In brief, this structure can be easily configured by cutting the bottom surface of the conventional tray 22 (refer to FIG. 1) into a quadrangular shape.

In addition, a fixing groove is formed at the free end of the tray frame 22 'so that the rotating shaft 30 (shown in dashed lines) formed on both sides of the tray pivot 22-2 is fixed. Therefore, the tray pivot 22-2 can rotate about the front end of the tray frame 22 'by applying an appropriate force from the lower side.

In addition, a tray protrusion 22-4 is formed on a lower surface of the tray pivot 22-2. The tray protrusion 22-4 is used to rotate the tray pivot 22-2, and the second rod 38 of the tray operating means M described later is inserted therein.

The tray protrusion 22-4 is shown as a long and thin groove in the present invention, but it will be readily understood by those skilled in the art to which the present invention pertains that its shape can be changed depending on the type of rod used.

In addition, the tray protrusion 22-4 is preferably installed adjacent to one of both side ends of the tray rotating unit 22-2 so as not to disturb the course when the pizza is recovered.

The tray operating means M, which is a means for rotating the tray pivot 22-2, includes a drive motor 32, a rotation shaft 34 extending from the drive motor 32, and the rotation shaft 34. The first link 36 is connected, and the second link 38 is connected to the first link (36). In particular, the rotary shaft 34 and the first link 36, the first link 36 and the second link 38 are connected by the moving shaft 44, 42, respectively, the second link 38 in the middle It is impossible to move by the fixed shaft (40). Accordingly, the second link 38 rotates about the fixed shaft 40.

As shown in FIG. 2, the fixed shaft 40 may have a structure such as an extension rod a that may be fixed to a wall surface (not shown) existing on the lower side of the microwave oven.

The tray operating means M according to the present invention, in particular, is spaced apart from each other so as not to prevent the tray frame 22 'and the tray pivot 22-2 from moving horizontally in order to eject the pizza to the buyer.

Although not shown, the drive motor 32 is operated by a control signal output from the controller to rotate the rotation shaft 34 along the arrow A in the circumferential direction. When the rotating shaft 34 rotates, the first rod 36 moves toward the driving motor 32, and the second rod 38 connected to the first rod 36 is centered on the fixed shaft 40. Free end (e) that is not connected by rotating to move upward. The free end e thus moved is inserted into the tray protrusion 22-4 to rotate the pizza tray pivot 22-2 about the rotation shaft 30.
