The invention relates to an automatic protection device for steel billet roller ways. Incoming steel billets are conveyed to a weighing roller way through a conveying roller way, wherein a guide device is arranged between the weighing roller way and the conveying roller way adjacent to the weighing roller way, and a guide plate of the guide device is operated by a hydraulic cylinder to ascend and descend to control the ascending and the descending of the steel billets on the conveying roller way; a proximity switch for detecting whether the guide plate ascends and descends or not is arranged on the guide device; a cold metal sensor for tracking and detecting following steel billets is arranged in front of the guide device according to an incoming direction; the proximity switch, the cold metal sensor and the output end of a weigher are connected to a PLC (programmable logic controller) of a conventional roller way control system; one output end of the PLC is connected with a control circuit of the hydraulic cylinder. According to the device, the following moving steel billets are kept out of contact with the steel billet which is weighed, the number of the steel billets contacting with the roller ways and the contact areas of the steel billets and the roller ways are reduced, the magnitude of stress and the stress direction are eliminated, and equipment damage caused by collision between the steel billets is eliminated.

The invention discloses an unmanned vending method, relating to the field of unmanned supermarkets. The method comprises the steps of: firstly, obtaining an initial mass of a first commodity before the current purchase operation, and opening a discharge control valve of a storage bin corresponding to the first commodity; collecting the mass value of the storage bin continuously and intermittently;then, according to the mass value and the initial mass, solving the discharge mass of the first commodity discharged by an unmanned vending machine; and finally, in response to the difference betweenthe discharge mass and the purchase mass being less than a first threshold, closing the discharge control valve to complete the purchase and discharge task of the first commodity. The method solves the weighing problem of unmanned vending, increases the variety of commodities in unmanned vending by weighing and selling the commodities, and enhances the adaptability of the unmanned supermarkets tothe commodity requirements, and meanwhile, the method also avoids the condition that a user takes out the first commodity discharged without weighing, thus reducing the commodity loss rate of the unmanned supermarkets.

The invention discloses a logistics packaging information collection device based on the Internet of Things, which includes a bottom plate, and is characterized in that: the bottom plate is fixedly connected to a vertical plate, the vertical plate is fixedly connected to a U-shaped groove, and the U-shaped groove is fixedly connected to a round rod. One end of the round bar one, the other end of the round bar one is fixedly connected to the base plate, a square plate one is arranged in the U-shaped groove, the square plate one is fixedly connected to the round bar three, and the round bar three is fixedly connected to a distance sensor Two, the U-shaped groove is fixedly connected to the second round bar, the second round bar is fixedly connected to the other distance sensor two, the vertical plate is fixedly connected to the symmetrical round bar four, and the vertical plate is fixedly connected to the horizontal bar, so The horizontal bar is fixedly connected to a group of evenly distributed distance sensors 1, and the vertical plate is fixedly connected to the collection mechanism. The invention relates to the field of logistics equipment, in particular to a logistics packaging information collection device based on the Internet of Things. The invention facilitates the collection of packing box information.

The invention discloses an automatic static metering system and an automatic control method for continuous material unloading at a dock. The automatic static metering system comprises a material distributor of a material conveying device, a material weighing device, a metering operation station, a local metering server, a PLC and a basic automatic operation station. The material weighing device is composed of a first weighing hopper, a second weighing hopper, a first weighing sensor set, a second weighing sensor set, a first weighing instrument and a second weighing instrument. The PLC controls the material distributor and a hydraulic drive device of the material weighing device. The PLC, the first weighing instrument and the second weighing instrument are connected with the metering operation station. The metering operation station is used for reading signals of the PLC and data displayed by the first weighing instrument and the second weighing instrument in real time and storing the data in the local metering server. The basic automatic operation station controls the PLC. Information of bulk materials on ships from the moment when the materials enter the dock to the moment when the materials are weighed and unloaded is mastered comprehensively, and the material metering accuracy is improved.
