Modular shelf vending machine

Abstract

A modular shelf-type automatic vending machine includes: a chassis with an operation screen at the front end, a control host, and a dispensing port; a machine platform located inside the chassis, forming a storage shelf and a work corridor; and a retrieval and displacement mechanism located on the machine platform and in the work corridor, electrically connected to the control host. The retrieval and displacement mechanism has a telescopic stainless steel spring on the Z-axis host, a bucket at the upper end of the telescopic stainless steel spring, and a retention buckle on one side of the machine platform. The machine platform is used to place the item on the storage shelf, and the retrieval and displacement mechanism, the Z-axis host, and the Z-axis drive mechanism are used for XYZ axis displacement to retrieve the item through the bucket and deliver it to the rear end of the dispensing port. The retention buckle is used to position the item at the dispensing port.

The side rails are located on both sides of the central slide rails arranged opposite to each other. Each central slide rail has a guide groove on its inner side and a Y-shaped guide opening at its rear end. A pick-and-place mechanism is located on the machine platform, in the work corridor, and electrically connected to the control unit of the operating screen. The upper section of the pick-and-place mechanism has at least one X-axis upper slide rail and an X-axis upper slide block. The lower section of the pick-and-place mechanism has at least one X-axis lower slide rail and an X-axis lower slide block. A Y-axis rail post and a Y-axis slide block are located on both sides of the X-axis upper slide block and the X-axis lower slide block. The X-axis upper slide block has an X-axis drive motor and chain teeth at its end. The X-axis upper slide rail is connected to the chain teeth at the front end of the X-axis drive motor. One of the X-axis chains; the Y-axis slide has a Y-axis motor and chain teeth at its end; the Y-axis slide has a Y-axis chain connected to the chain teeth at the front end of the Y-axis drive motor; the Y-axis slide has a forward-protruding Z-axis main unit; the Z-axis main unit includes multiple movable slide rails and multiple movable side rails; the movable side rails are located on both sides of the movable slide rails arranged opposite each other; the inner side of the movable slide rails has an opposing inner guide groove; the Z-axis main unit corresponds to the rail of the storage compartment shelf, and the movable slide rail has a Y-shaped guide corresponding to the guide groove. The sliding rail has a gap, and the movable side rail corresponds to the side rail and also has a gap. A Z-axis drive mechanism is provided at the lower end of the Z-axis main unit. The Z-axis drive mechanism includes a telescopic stainless steel spring wound into the shape of a measuring tape, and a Z-axis drive motor connected to the center of the telescopic stainless steel spring. The telescopic stainless steel spring is sleeved in the inner guide groove of the Z-axis main unit located inside the movable sliding rail. A bucket corresponding to the side rail and the column plate is located at the upper end of the telescopic stainless steel spring at the upper end of the Z-axis main unit. The rear end of the scooping port is provided with... The machine has two front side rails on both sides and two middle rails in the center of the front side rails. A bucket base is provided at the upper end of the bucket to provide Z-axis displacement. The front side rails and the middle rails are opposite to the front end of the side rail and the middle slide rail on one side of the storage compartment and form at least twice the space for placing items. The front side rails and the middle rails are provided with a retaining buckle at the upper end of the corresponding side rail and the middle slide rail. The front upper section has a long ear and a limiting pin at the lower end of the long ear. The upper rear section of the retaining buckle is provided with a shaft pin to allow the retaining buckle to be lifted and rotated upward. The item is placed in the storage compartment. The pick-up displacement mechanism, the Z-axis host and the Z-axis drive mechanism are used to perform XYZ axis displacement. The bucket provided at the end of the telescopic stainless steel spring is used to pick up the item and send it to the front side rail and the middle rail opposite to the Z-axis host at the rear end of the pick-up port on one side of the machine. The retaining buckle is used to fix the item to prevent it from retracting.

2. The modular shelf-type automatic vending machine as described in claim 1, wherein, The access port of the chassis is located at the bottom of the operating screen in a convenient position for easy access.

3. The modular shelf-type automatic vending machine as described in claim 1, wherein, The machine tool is equipped with a signal ruler on the left and right sides and on the top and bottom sides at the rear end, which facilitates accurate positioning of the X and Y axes.

4. The modular shelf-type automatic vending machine as described in claim 1, wherein, The Z-axis drive mechanism has a base plate on each side of the telescopic stainless steel spring. The telescopic stainless steel spring, which is wound into the shape of a measuring tape, has multiple binding bearings on the outer periphery of the base plate on both sides, so that the circular motion is converted into linear motion.

5. The modular shelf-type automatic vending machine as described in claim 4, wherein, The bucket system includes a box-shaped bucket or a bottle bucket in a semi-circular arc shape, which can be freely changed according to the shape of the item.
