Description

Swing arm mechanism of vending machine

The present invention relates to a rotating arm mechanism, and more particularly to a vending machine for transporting items sold by a vending machine in a rotating swing arm.

It is known that the existing vending machine controls the internal control circuit of the vending machine to activate a two-axis (XY axis) or three-axis (XYZ) robot arm after the customer operates the order through the human-machine interface, so that the two-axis or three After the mechanical arm of the shaft is moved to the display area of the item to be removed, the two- or three-axis robotic arm moves the item to the sliding track, allowing the item to automatically slide to the vending machine exit, or The two- or three-axis robotic arm directly delivers the item to the vending machine outlet for the customer to pick up.

Due to the above-mentioned two-axis or three-axis robotic arm design of the vending machine, the goods sold by the customer can be sent to the outlet of the vending machine. However, the two- or three-axis robotic arm of such a vending machine is only suitable for transporting bottles, canned beverages or articles packed in bags or boxes, and is not suitable for handling hot foods with soups. In the sale of goods, because the two-axis or three-axis robotic arm is transported at a faster speed, it is easy to cause the hot soup to spill when carrying the hot food containing the soup. Therefore, in order to be able to carry a merchandise containing hot soup, it is necessary to redesign the mechanism for carrying the merchandise.

The opening 52 enables the rotating arm 50 to be fixed. Connected to the transmission shaft 43, a bent-shaped hook portion 53 extends from the other end of the arm portion 51. The hook portion 53 can hook out the merchandise items carried on the adjacent mechanism (shown in the figure).

The transition module 60 is disposed on the side of the upper plate 11 of the fixed base 10. The transition module 60 has two symmetrical pivoting portions 61, and an actuating plate 62 is pivotally connected between the two pivoting portions 61. The transition module 60 is reset by a magnet, and functions to compensate for the gap between the adjacent mechanism and the carriage 30, so that the item to be withdrawn is stably introduced onto the carriage 30.

Please refer to Figure 3-6, which is a schematic diagram of the three-dimensional motion of the rotating arm mechanism and the top view of the items. As shown in the figure: in the present invention, the swing arm mechanism 100 is disposed inside the vending machine, and after the adjacent institution (not shown) takes out the sold item, the control circuit of the vending machine (not shown) The stepping motor 20 is driven to rotate, so that the rotating shaft 21 of the stepping motor 20 drives the transmission module 40 to rotate. When the rotating arm 50 is driven, the rotating arm 50 first swings to one side, and the adjacent mechanism will be The item is sent to the side of the tray 30. When the item is the bowl 200, the hook portion 53 of the rotating arm 50 will hook the bowl 201 of the bowl 200 to make the bowl 200 The protruding portion 202 spans the upper edge of the hook portion 53 and is sent to the carriage 30 after the rotating arm 50 hooks the bowl 200, and the mechanism is adjacent to the other side of the rotating arm mechanism 100 (not shown) When it arrives, the control circuit drives the stepping motor 20 again, causing the rotating arm 50 to hook the bowl 200 to the mechanism on the other side.

When the rotating arm mechanism 100 hooks the bowl 200 onto the carriage 30, the actuating plate 62 of the transition module 60 will actuate to compensate for the gap between the adjacent mechanism and the carriage 30, so that the items to be withdrawn are stably introduced. On the carriage 30.
