Description

Technical Field

[0001] The utility model relates to the technical field of lifting containers, in particular to a front and rear over-pallet detection mechanism for a vertical lifting container. Background Art

[0002] The automated warehousing system is composed of high-rise stereoscopic shelves, stackers, various types of forklifts, warehousing systems, unmanned guided vehicles, control systems and peripheral equipment. The automated warehousing system can make full use of storage space, realize online control of equipment through computers, handle items quickly and accurately based on the principle of first-in-first-out, and reasonably carry out inventory management and data processing. In the automated warehouse vertical lifting containers, there are automatic height measuring devices for goods, but there is no over-pallet detection technology before and after the goods. When the operator places the goods without paying attention to the goods exceeding the front and rear fences of the pallet, there is a risk of the pallet hitting other pallets during the lifting process, causing damage to the goods or jamming the pallet to generate failures. Therefore, how to realize the over-pallet detection function before and after the goods and completely avoid such equipment failures has become the direction of research.

[0003] However, the traditional technology for detecting the front and rear over-pallet of goods cannot meet people's needs, and it has the following defects: First, it is necessary to require operators to place the goods in the pallet enclosure. For stacked goods, special attention should be paid to whether the pallet is neatly stacked in the front and rear directions and whether it exceeds the outer edge of the pallet. However, it is inconvenient to check the back of the pallet. Once a collision occurs, the goods will be squeezed and damaged. More seriously, it may cause mechanical deformation of the pallet and the lifting trolley. Professionals are required to troubleshoot the problem, which results in a large loss of time and economic costs. Second, due to the principle structure of the vertical lifting container, the lifting trolley is limited in the horizontal pushing and pulling direction of the pallet and cannot increase the distance travel, resulting in the inability to install an independent front and rear distance measuring device. It can only rely on manual detection, which requires high experience and is relatively inefficient. Utility Model Content

[0004] The utility model aims to provide a mechanism for detecting the front and rear over-pallet of goods in a vertical lifting container, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a front and rear over-pallet detection mechanism for a vertical lifting container cargo, comprising a loading pallet, both ends of the loading pallet are fixedly connected with a front connecting piece and a rear connecting piece, a second pallet position detection hole is opened on one side outer wall of the front connecting piece, and a first pallet position detection hole is opened on one side outer wall of the rear end connecting piece.

[0006] As a further technical solution of the utility model, a height measuring light curtain is arranged at one end of the loading tray, a light curtain emitting hole is opened on one outer wall of the height measuring light curtain, and a light curtain receiving hole is opened on the other outer wall of the height measuring light curtain.

[0007] As a further technical solution of the utility model, a support frame is sleeved on one side outer wall of the height measuring light curtain, a second bolt is threadedly connected to the support frame, and the second bolt is threadedly connected to one side outer wall of the height measuring light curtain.

[0008] As a further technical solution of the utility model, a mounting bracket is sleeved on one end of the altimeter light curtain, a first bolt is threadedly connected to an outer wall of one side of the mounting bracket, and the first bolt is threadedly connected to an outer wall of one side of the altimeter light curtain.

[0009] As a further technical solution of the utility model, the other end of the height measuring light curtain is fixedly connected to a mounting base.

[0010] As a further technical solution of the utility model, a cable is fixedly connected to an outer wall of one side of the mounting base, and the cable is arranged on the height measuring light curtain.

[0011] As a further technical solution of the utility model, a cargo body is arranged on the top of the loading tray.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model uses a novel design with two sets of side through holes on the pallet, which can be used in conjunction with a detection device to detect the front and rear directions of the stacked goods on the pallet, effectively judging whether the goods are neatly stacked or exceed the outer edge of the pallet, etc. It is more convenient and quicker than manual detection, and can effectively prevent collisions between goods, resulting in damage to the goods by squeezing, mechanical deformation of the pallet and the lifting trolley, and other faults; at the same time, there is no need to add new independent detection devices, and the existing height measuring light curtain of the container is used for detection, which does not occupy the horizontal push-pull pallet space size of the lifting trolley in the container, effectively avoiding the distance limitation of the lifting trolley for hooking the pallet in the horizontal direction, and solving the technical defects in this regard.

[0024] Working principle: When using the utility model to detect the front and rear over-pallet of the vertical lifting container, first stack the cargo body 5 on the loading pallet 4, and put it into storage after stacking. At this time, the height measuring light curtain 1 is started through the cable 13, and the infrared light beam is emitted through the light curtain emitting hole 10 on the height measuring light curtain 1, and the reflected light is received through the light curtain receiving hole 15. When the object enters the light beam, the object blocks part of the light, causing the light beam received by the light curtain receiving hole 15 to change. By monitoring the change of the light beam, the controller on the height measuring light curtain 1 can determine the position and movement of the object. When the first pallet position detection hole 2 on the rear end connecting piece 12 passes through the detection range of the height measuring light curtain 1, the height measuring light curtain 1 extracts all detected signals to determine whether there is cargo on the pallet exceeding the longitudinal facade of the first detection position. When the second pallet position detection hole 3 on the front connecting piece 11 passes through the detection range of the height measuring light curtain 1, the height measuring light curtain 1 also extracts all detected signals to determine whether there is any cargo on the pallet exceeding the longitudinal elevation of the second detection position, thereby realizing the function of detecting the out-of-tolerance dimensions of the cargo in the front and rear of the cargo. Regardless of the first detection position or the second detection position, when a cargo blocking signal is detected at the position, it is determined that the cargo exceeds the pallet, and the system automatically returns the pallet to the operating table and clearly prompts the operator on the operating terminal that the front / rear dimensions of the cargo exceed the pallet range, requiring the operator to re-arrange the cargo before it can be put into storage again; wherein the mounting bracket 6 is fixed to the height measuring light curtain 1 by the first bolt 9, the support frame 8 is fixed to the height measuring light curtain 1 by the second bolt 14, and the height measuring light curtain 1 is fixed by the mounting bracket 6, the mounting base 7 and the support frame 8.
