Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned supermarkets, unmanned vending machines and automatic warehouses, and particularly relates to a cargo aisle control device for unmanned vending machines and automatic warehouses. Background Art

[0002] While vending machines on the market offer a wide variety of functions, their aisle types are quite limited. There are common spring and spiral aisles and crawler aisles, as well as sophisticated S-shaped stacking aisles and clustered lattice cabinets. The following briefly describes the advantages and disadvantages of these aisles, and how to choose the right one for your vending machine business.

[0003] 1. Spring spiral cargo channel

[0004] Spring spiral aisles offer a simple structure and a wide variety of merchandise, including common snacks and bottled beverages. Their advantages are low cost and a wide variety of merchandise. Their disadvantages are that they cannot be adjusted freely, limiting the variety of merchandise available. They can also easily get stuck when selling bottled beverages, making restocking difficult.

[0005] 2. Crawler cargo track

[0006] Tracked aisles are an extension of spring aisles and have more restrictions. They are suitable for selling products with fixed packaging that are not prone to tipping over. Their advantages include being able to sell a variety of stable products such as short canned beverages, short boxed snacks, and boxed lunches. Their disadvantages are that the aisle width cannot be adjusted arbitrarily, limiting the variety of products sold. Products that are not stable can easily tip over, making restocking difficult.

[0007] 3. S-shaped stacking aisle

[0008] The S-shaped stacking aisle is a specialized aisle developed specifically for beverage vending machines. It can handle a variety of bottled and canned beverages. Drinks are stacked layer by layer within the aisle, and the containers are discharged by gravity, preventing jams. The advantages of this stacking aisle are high space utilization, a wide variety of beverages can be sold, no jams, and simple delivery. However, the disadvantages are its complex structure, high design and processing requirements, and high manufacturing costs.

[0009] 4. Multi-door lattice cabinet

[0010] A multi-door lattice cabinet is a cluster of lattice cabinets. Each lattice has a separate door and control mechanism. Each lattice can hold one product or a set of products.

[0011] The advantage is that it can sell a variety of goods without restrictions on shape and size, and its construction is simple and its manufacturing cost is low; the disadvantage is that it can accommodate a relatively small number of goods and the space utilization rate is relatively low. Summary of the Invention

The pulley is connected to the track, the tension spring is arranged between the fixed wheel and the movable pulley, the movable pulley is slidably installed on the guide rail through the slide seat, there are two pull wires, one of which is connected between the rear end of the crawler and the ratchet, and one end of the other pull wire is connected to the front end of the crawler, and the other end is fixed to the casing after passing through the fixed wheel, the first fixed pulley, and the movable pulley in sequence. The crawler is slidably installed on the frame, and the frame is fixed to the casing. A micro switch is provided at the shipping port of the frame, and the micro switch is connected to the motor; the working principle of this device The principle is: when loading goods, an electric wrench is used to drive the ratchet to rotate, thereby pulling the crawler of the cargo aisle from the front end to the rear end through the line connected to the rear end of the crawler, so that the entire crawler is laid flat on the frame, and at the same time the tension spring is stretched to the maximum. Because there is a one-way ratchet device, the ratchet remains stationary when the electric wrench is removed, and the crawler will not slide forward due to the return force of the tension spring. When the goods need to be shipped, the motor will rotate, thereby driving the eccentric mechanism composed of the driving gear, the driven gear, the eccentric shaft and the transmission mechanism to move, so that the ratchet can rotate in a controlled manner, and then the pull wire connected to the ratchet is relaxed, and the crawler moves under the action of the return force of the tension spring, so that the front end of the crawler passes around the fixed wheel and moves to the lower side of the frame, so that the goods are shipped from the front end of the frame. When the goods fall, the micro switch will be triggered, and the micro switch controls the motor to stop rotating. The crawler will remain stationary due to the action of the ratchet, thereby completing a shipment. At the same time, this device can adjust the width of the cargo aisle according to the size of the goods. It only needs to adjust the distance between the two pulleys and replace the corresponding crawler.

[0014] Furthermore, the crawler track is a half-circle crawler track, two guide rails are arranged in parallel, and the tension spring is arranged between the two guide rails, which has a reasonable structure and stable operation.

[0015] Furthermore, a ratchet pawl mechanism is formed between the ratchet and the latch, and a reset spring is provided; two latches are arranged circumferentially along the ratchet, and the transmission mechanism includes a rocker arm and a connecting rod, the middle part of the rocker arm is rotatably mounted on the casing through a rotating shaft, the two ends of the rocker arm are respectively connected to a latch, and the connecting rod is connected between the rocker arm and the eccentric shaft; the eccentric shaft rotates one circle, driving the rocker arm to swing one cycle, so that the two latches complete a forward and backward action respectively, and then control the ratchet to rotate one tooth, and repeat this cycle, so that the crawler track moves forward in a controlled manner, thereby realizing the delivery of the goods on the cargo aisle.

[0016] Furthermore, the driven gear, the eccentric shaft and the connecting rod form an eccentric rotation mechanism, which converts the rotation of the motor main shaft into the reciprocating motion of the two bayonet pins.

[0017] Furthermore, a hexagonal shaft is provided on the side of the ratchet. The hexagonal shaft makes it convenient to insert the hexagonal shaft into the electric wrench with a 90-degree hexagonal angle when loading goods. The electric wrench drives the ratchet to rotate, thereby pulling the track of the cargo channel from the front end to the rear end through the pull wire connected to the track, and at the same time the tension spring is pulled to the maximum.

[0018] Furthermore, baffles are provided on the crawler tracks. This device adjusts the width of the cargo aisle according to the size of the cargo.
