Description

Technical Field

[0001] The utility model relates to the relevant field of stereoscopic warehouses, in particular to a size detection device for automatic stereoscopic warehouses. Background Art

[0002] The automated stereoscopic warehouse (AS / RS system) is an automated logistics storage system that fully utilizes space to achieve high automation of goods storage, high-speed storage and information integration, and is completely controlled by computers. It is usually a complex automated logistics system composed of stereoscopic shelves, rail-mounted aisle stackers, in-and-out conveyor systems, shuttles, robots, AGV carts, size detection barcode reading systems, communication systems, automatic control systems, computer monitoring systems (WCS), computer management systems (WMS) and other auxiliary equipment such as wire and cable tray distribution cabinets, pallets, adjustment platforms, steel structure platforms, etc. Using the concept of integrated logistics, adopting better control, bus, communication (wireless, infrared, etc.) and information technology (RFID, etc.), through the coordinated linkage of the above equipment, automatic in-and-out storage operations are controlled by computers, which can automatically realize functions such as receiving, palletizing, warehousing, out-of-warehouse, picking, inventory maintenance, delivery, inventory statistics and alarms, and report generation.

[0003] Automated high-bay warehouse systems are widely used in various industries such as machinery, electronics, chemicals, medicine, tobacco, aerospace, rail transit, etc. Materials stored in high-bay warehouses need to be inspected for size before transportation and storage to see if the size meets the standards. This is mainly to detect the height. Otherwise, materials with non-compliant sizes will touch the existing structure during transportation, causing equipment downtime and affecting the normal logistics transportation and storage functions.

[0004] At present, many size detection devices use laser detection or infrared detection and other means to perform size detection, but the detection is mainly single-point detection. When the stored material is partially over-height but not over-height in other places, it is difficult for this detection method to detect that the size is not in compliance with regulations. In addition, for stereoscopic warehouse storage, it is not necessary to accurately detect the dimensions of the stored materials, but only to determine whether they are over-height. A large number of precise detection structures have a waste of functions. Utility Model Content

[0005] The purpose of the utility model is to provide a size detection device for an automatic stereoscopic warehouse to solve the problem raised in the above background technology that many current size detection devices are single-point detection. When the stored material is partially over-height but not over-height at other locations, it is difficult for the detection method to detect that the size is not in compliance with the regulations. In addition, for stereoscopic warehouse storage, it is not necessary to accurately detect the various dimensions of the stored materials, but only to determine whether they are over-height. A large number of precise detection structures have the problem of functional waste.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a size detection device for an automatic stereoscopic warehouse, comprising a support beam, a horizontal L-shaped plate is welded and fixed in the middle of the front end of the support beam, first driving cylinders are installed on both sides of the upper end of the horizontal plate of the horizontal L-shaped plate, a lower horizontal plate is arranged at the lower end of the horizontal plate of the horizontal L-shaped plate along the output rod ends of the two first driving cylinders, a center sleeve is fixed in the middle of the upper end of the horizontal plate of the horizontal L-shaped plate, an upper fixing ring is fixed at the upper end of the center sleeve, a center column is fixed in the middle of the upper end of the lower horizontal plate, an upper end of the center column passes through the horizontal plate of the horizontal L-shaped plate and the center sleeve to fix an upper fixing plate, connecting conductive sheets are arranged on both sides of the lower end of the upper fixing plate and both sides of the upper end of the upper fixing ring, and the upper and lower connecting conductive sheets conduct electricity after contact.

[0007] Preferably, a sensor plate is embedded and installed in the middle of the lower end of the lower horizontal plate.

[0008] Preferably, support columns are welded and fixed to both sides of the lower end of the support beam, and a support plate is welded and fixed to the lower end of the support column.

[0009] Preferably, a vertical L-shaped plate is welded and fixed to the lower end of the front end of the support column, a second driving cylinder is installed in the middle of the outer end of the vertical plate of the vertical L-shaped plate, and a limiting baffle is fixed on the inner side of the vertical plate of the vertical L-shaped plate along the output rod end of the second driving cylinder.

[0010] Preferably, the limit baffle is composed of a front baffle, a side baffle and an oblique guide portion, the front baffle, the side baffle and the oblique guide portion are arranged in sequence, the front baffle, the side baffle and the oblique guide portion are integrally formed, the front baffle and the side baffle are vertical, and the oblique guide portion is inclined.

[0011] Preferably, a vertical limit rod is fixed in an array on the upper end of the lower horizontal plate, a vertical sleeve is fixed on the upper end of the horizontal plate of the horizontal L-shaped plate along the upper end of the vertical limit rod, the vertical limit rod slides along the horizontal plate and the vertical sleeve of the horizontal L-shaped plate, and an end is fixed at the uppermost end of the vertical limit rod.

[0012] Preferably, the four end corners of the vertical plate of the vertical L-shaped plate are slidably connected with horizontal limit rods, the outer end of the horizontal limit rod is fixed with a limit end head, and the inner end of the horizontal limit rod is fixed to the side stop.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the output rod end of the first driving cylinder extends to drive the lower horizontal plate to move downward, and the center column and the upper fixed plate move downward. When the connecting conductive sheet at the lower end of the upper fixed plate contacts the connecting conductive sheet at the upper end of the upper fixed ring, a signal is sent to the central controller, and the output rod end of the first driving cylinder stops extending. As long as the central controller can receive the signal sent by the connecting conductive sheet, it means that the goods are not over-height and can be put into storage, which solves the problem that the current stereoscopic warehouse storage does not need to accurately detect the dimensions of the stored materials, but only needs to determine whether it is over-height, and a large number of precise detection structures have functional waste.

[0015] 2. In the utility model, the output rod end of the first driving cylinder is extended to drive the lower horizontal plate to move downward. When the sensor plate on the lower horizontal plate contacts the upper end surface of the goods, a signal is sent to the central controller. No matter which part of the upper end of the goods is super high, as long as the sensor plate on the lower horizontal plate contacts the highest point of the goods, the first driving cylinder stops driving. In this state, size detection is performed, which can solve the problem that many current size detection devices are single-point detection. When the stored material is partially super high but other positions are not super high, the detection method is difficult to detect the problem of non-compliant size, and the detection surface is more comprehensive.

[0016] 3. In the utility model, before the goods arrive, the output rod end of the second driving cylinder extends to drive the limit baffle to move toward the direction of the goods. When the goods are transported by the conveying device to the lower end of the size detection device, the oblique guide part, the side baffle and the front baffle on the limit baffle adjust the posture of the goods. After the posture is adjusted, the output rod end of the second driving cylinder shrinks. The shrinking process and the detection process occur simultaneously. After the detection is completed, this part of the structure does not affect the passage of the goods. This part of the structure does not increase the operation time, but can help the goods to be stored more regularly, which is convenient for the use of the entire logistics storage line.
