Abstract
The utility model provides a hanging chain hook scale, which is an electronic scale which is installed on an overhead conveyor by a weight-bearing force transferring mechanism, and is characterized in that the utility model adopts a weighing sensor to hang a novelplatform whose shape is like the Chinese character 'jing', applies an A/D conversion channel and a single-board microcomputer system to control the utility model with the overhead conveyor to realize the dynamic automatic weighting and display, print, and automatic removing tare to material which is conveyed by a chain hook, can accumulate tabulation, and can also do static weighting. The highest accuracy class of an automatic scale can be achieved, and the operation is stable and reliable.
Description
The utility model relates to a kind of dynamic auto electronic scales, also can be used for static weighing.
Suspension type chain hook scale is that the load-bearing force transmission mechanism is installed on the online dynamic auto weighing system on the overhead chain conveyer, and amorphous products still both at home and abroad is all in the development stage.Existing micro computer suspension electronic scale does not reach the requirement of dynamic calibration precision 0.2% through test of many times, can not successful Application.Its subject matter is the stable bad of load-bearing force transmission mechanism, and may introduce than mistake, and the Dynamic Data Processing model that is difficult to select to be suitable for reaches the weighing requirement.
The purpose of this utility model is to provide a kind of suitable high precision chain hook scale, with the needs of the supporting on-line automatic weighing system of solution introducing equipment, and can be supporting with the overhead chain conveyer of other use occasion, as commercial scale.
The utility model is achieved in that the top that the weighing platform of electronic scales is installed in the overhead chain conveyer track, and the weighing platform table top is a suspension type.Adopt novel class intersecting parallels weighing platform, fulcrum adopts the strong S type sensor of lateral force resistance all outside emphasis, hangs weighing platform with the movable syndeton, can self-poise, stablize center of gravity; Corresponding this structure adopts heading spacing, and it is little to introduce the additional force influence, has carried out sensor uniformity compensation and weighing linear compensation, adopts quick 16 A/D ALT-CH alternate channels of high precision and single boar microcomputer system, comprises suitable application software.In addition, sensor directly is suspended on the conveyor support beam with crossbeam, must not establish support in addition.
The utility model relatively has original characteristics with existing similar technology, in March, 1989 by measurement verification department by the measurement verification regulations JJG(AG that adopts international standards to formulate) 09-89 " suspension type chain hook scale " assay approval, static accuracy meets III level scale standard, dynamic accuracy reaches 0.1%, meets pin-point accuracy grade 0.2 grade standard of automatic balance of OIML (OIML) regulation.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Below in conjunction with accompanying drawing utility model is further described in detail.
Accompanying drawing is the mounting structure figure of the utility model weighing table part.
With reference to accompanying drawing; bearing sensor and upper end are fixed on entablature 3 two ends with connecting rod movable web member 4 respectively; crossbeam 3 usefulness fixed heads 2 are fixed in conveyor support beam 1; sensor 5 lower ends hang sill 7 with steel cable movable web member 6 respectively; sill 7 is connected with weighing platform girder 8; and connect weighing tracks 11 with web member 9; weighing track 11 aligns with conveyor rail and joins; gap 3～5mm; weighing platform is spacing with 4 groups of heading stops 10; the apical grafting gap is adjusted into 0.5～1mm, and two groups of chain type safety features are arranged between entablature 3 and the sill 7, but to do safeguard protection and to guarantee more emat sensor or conveyor operate as normal still during web member.When hanging the chain hook weighing, the chain hook and the weight of carrying are subjected to the single successively weighing platform weighing rail that passes through of chain control, and its Control System of Microcomputer is same as the prior art, in use deducts the chain hook deadweight automatically, can show data such as printing net weight and cumulative weight, stable and reliable operation.
Claims (2)
1, a kind of by the weight-scale table plane system, weighing sensor, the suspension type chain hook scale that major parts such as A/D ALT-CH alternate channel and single boar microcomputer system are formed is characterized in that:
A, described weight-scale table plane system are the whole novel class intersecting parallels weighing platform structure outside emphasis of fulcrum.
B, described weighing sensor, entablature is fixed in connecting rod movable web member in the upper end, is fixed on the conveyor support beam by crossbeam, and the lower end hangs sill with steel cable movable web member, hangs weighing platform by crossbeam.
2, suspension type chain hook scale according to claim 1, it is characterized in that novel class intersecting parallels weighing platform and hanging active structure is to adopt the heading stop means.
