Description
Technical field
The present invention relates to a kind of reflection type optical fiber beam plastics logistics tray bending degree detecting device more particularly in plastic tray
Disk mechanics key position detects curvature device, belongs to logistics detection device technical field.
Background technology
Plastics logistics tray is the matching used Logistic Units of logistics equipments such as a kind of and fork truck, shelf.Can be used to store,
It loads, transport goods, be one of essential logistics equipment in Modern Materials Circulation storage.China Federation of Logistics ＆ Purchasing holds in the palm
The preliminary investigation of disk Professional Committee is shown：China now possesses about 50,000,000~70,000,000, various types of pallet, and annual output is passed
Increase 20,000,000 or so.Wherein plastic pallet accounts for 8%.
Plastics logistics tray often carries out sampling check for quality when manufacture circulates, up-to-standard to ensure, but makes
With in the process, because of the breakage of plastics logistics tray, aging, the Structural Faults caused by long-time service situations such as, still lack at present effective
Technology detection means.
For plastics logistics tray in manufacture, quality is general related with the batch of the material used, production, and makes daily
With the logistics links difference that in the process, each plastics logistics tray reaches, operations number is different, mode of transport is different, so
Its breakage is also just different, therefore cannot use sampling observation mode, but needs to carry out general inspection.
Unified examination criteria there is no at present with general inspection to plastics logistics tray, also only resting on artificial judgment, using year
The superseded method of limit, subjectivity is strong, and error is big, is unfavorable for plastics logistics tray scientific management.
According to retrieval, the automation of plastics logistics tray has with detection：The Chinese invention of Publication No. CN104535576A
Patent《A kind of frontlighting light source plastic pallet inspection damage device and method》, disclose and moulded using machine vision technique means automatic identification
Logistics tray breakage is expected, using the quantitative basis whether eliminated as decision；
At present, the breakage of machine vision technique detection plastics logistics tray is only limitted to the breakage of tray surface appearance, right
It can not be detected in the internal mechanical structure change of plastics logistics tray, for the mechanical features of plastics logistics tray, such as stress
The features such as feature, fully loaded weight curvature can not detect.
And fully loaded weight curvature is an important availability aspect of plastics logistics tray, because storing in a warehouse in fully automatic stereo
In system, the carrying of plastics logistics tray is completed by automating shuttle machine, and the yoke of shuttle machine is after finely debugging
Automatically it performs, plastics logistics tray is fully loaded with weight curvature increase and causes shuttle machine yoke mechanical dimension mismatch, causes to carry event
Hinder and stereoscopic warehousing system is caused to stop, so as to cause efficiency and economic loss.
With the aging of plastic material, the defect of pallet mechanical structure, the fully loaded heavy curvature of plastics logistics tray is also sent out
Raw certain variation, therefore, it is necessary to the fully loaded heavy curvature to plastics logistics tray to carry out high-efficient automatic detection.
Invention content
The purpose of the present invention is to provide a kind of reflection type optical fiber beam plastics logistics tray bending degree detecting device, system knots
Structure is made of two tray supporters, two equipment guide rails, a pressure source, four fiber optic bundle detectors, two panels barn door；

Cube structure, length are slightly longer than the mountain font side edge length of plastics logistics tray, prop plastics logistics tray from bottom respectively
Two mountains font side；
The pressure source is rectangular parallelepiped structure, length and tray supporter equal length, and is parallel to tray supporter, from plastics
Logistics tray upper side center position is depressed naturally, and constant pressure external force is generated to plastics logistics tray；
Two equipment guide rails are mounted on the outside of the stud side of plastics logistics tray, four fiber optic bundle detectors point
An Zhuan not be on two equipment guide rails, and four stress of two stud sides of face plastics logistics tray respectively are small
Beam, stress girder lower section is engraved structure, and in plastics logistics tray forklift workability, four stress girders are the pass that mechanics squeezes
Key position；
The fiber optic bundle of the fiber optic bundle detector is sends optical fiber and reception optical fiber is one-to-one is staggered, fiber optic bundle face
Stress girder position, fiber optic bundle fibre end at least cover entire stress trabecular area；
The two panels barn door is mounted between two opposite fiber optic bundle detectors, and plastics logistics tray deformation leads to light
The output intensity that fine beam part sends optical fiber is not reflected by plastics logistics tray structure, and is directly entered opposite fiber optic bundle detector
Reception optical fiber, generate opposite fiber optic bundle detector interference, two panels barn door by these interference light intensity become scattered light intensity, make
It does not enter either fiber beam detector.
In conclusion the present invention significantly has technical effect that：Plastics logistics tray is fully loaded with using reflection type optical fiber beam
The crucial force part of curvature is detected afterwards, so as to avoid that the entirety that entire plastics logistics tray is fully loaded with rear deformation is swept
It retouches, fibre diameter is thin, and fiber optic bundle resolution is high, and present apparatus high degree of automation, detection efficiency are high, accuracy is high, for high-volume
Technological means is provided with mechanical features detection in continuing for circulation plastics logistics tray, is had broad application prospects.
