Abstract
The utility model discloses an array electronic belt weigher. An array weigher frame is formed by a plurality of single-idler weigher frames orderly arranged on a travelling belt according to requirements, an independent lead of the single-idler weigher frame is connected with a multi-path signal amplifying conditioner providing the functions of amplifying and debugging the weighting signal of each path independently and overlaying and conditioning the amplified signal into a one-path current output signal, the velocity of the travelling belt is detected by a pulse type velometer, the velocity pulse signal and the weighting current signal are input in a microcomputer for processing and calculating to obtain the material flow data, and the material integrating flow data can be obtained by integrating of the material flow data. The array electronic belt weigher in the utility model is particularly suitable for material flow detection under the conditions of longer travelling belt and larger change of belt tension and has detection precision far higher than that of the traditional electronic belt weigher.
Description
Technical field
The utility model relates to a kind of electronic installation that the travelling belt mass flow is accurately detected, and the mass flow that especially can be fit to longer equipment of conveyer detects.
Background technology
At present, industrial process generally adopts belted electronic balance to detect for the travelling belt mass flow, and the scale frame of employing mainly contains single mount roll-type, double bracket roll-type, many roller-types and floated etc.Though single mount roll-type scale frame compact conformation, easy for installation, but measuring accuracy is lower, double bracket roll-type, many roller-types and floated scale frame have higher precision under the prerequisite that application conditions satisfies, but the scale frame is long, have more than several meters, because the horizontal stress section of these scale framves is shorter, change belt greatly, long travelling belt (more than the 50m), the travelling belt that there is break-in the centre simultaneously for belt tension, be difficult to reach the higher detection precision, even can't satisfy minimum accuracy requirement.
Summary of the invention
Mass flow is detected the deficiency that exists in order to overcome existing belted electronic balance, a kind of array electronic belt conveyer scale is provided, this belted electronic balance detects for the mass flow of the bigger travelling belt of long or long travelling belt, tension variation, can reach very high accuracy of detection, have very strong adaptability.
The technical solution of the utility model is: under the prerequisite of travelling belt length permission, a plurality of single-idler receptors (general more than six) are installed, adorn one every 0.8 to 1 meter ampere, generally the many more measuring accuracy of single-idler receptor are high more, but when quantity acquires a certain degree, accuracy of detection does not have significant change, is principle to satisfy the accuracy of detection requirement generally.The scale frame must be chosen in roller place (more than the 2m) installation far away before and after equipment of conveyer, and guarantees that all stress points are on a line.All single-idler receptors outgoing cable respectively are connected with multiple signals amplification conditioner, after multiple signals amplify conditioner amplification, stack, conditioning, export the current signal of 4～20mA, are transported to computer processor by the current signal shielded cable.The travelling speed of travelling belt is detected by the pulsed velometer, and the pulse signal corresponding with speed of generation sent into computer processor.Current signal is calculated weight data after the AD conversion, pulse signal is calculated belt speed behind counting, and weight data and belt speed are in conjunction with calculating the flow that can obtain the travelling belt material.Outstanding feature of the present utility model is: (1) because single-idler receptor quantity is more, it is longer to cover belt, and the weight of material that is born is more much bigger than travelling belt tension variation amount, so the travelling belt tension variation is little to the accuracy of detection influence; (2) because single-idler receptor is that array is independently installed, its stress envelope horizontal segment is longer, helps obtaining higher precision; (3) single-idler receptor is installed and is debugged more convenient; (4) multiple signals amplification conditioner can be debugged each road signal amplification circuit separately, can guarantee the consistance of signal.
Description of drawings
Fig. 1 is an overall installation synoptic diagram of the present utility model.
Fig. 2 is a local scheme of installation of the present utility model.
Among the figure, the 1-single-idler receptor, 2-sensor mask cable, the 3-multiple signals amplify conditioner, 4-current signal shielded cable, 5-computer processor, 6-pulse signal shielded cable, 7-pulsed velometer, 8-fastening bolt, 9-belt frame, 10-travelling belt.
Embodiment
As shown in Figure 1 and Figure 2, array scale frame is made up of six (or more) single-idler receptors 1, roller does not have the place of break-in to install than far away and belt before and after the chosen distance travelling belt, single-idler receptor 1 evenly distributes, be about 0.8 meter to 1 meter apart, be fixed on the travelling belt frame by fastening bolt 8, travelling belt directly is pressed on the single-idler receptor 1, and the stress point that must make all single-idler receptors 1, travelling belt, belt roller is on same straight line.Each single-idler receptor 1 is drawn sensor mask cable 2 separately, load cell signal is connected to multiple signals amplifies conditioner 3, signal amplifies conditioner 3 can be debugged separately each road signal, has identical characteristic to guarantee each road signal amplification circuit.All measuring-signals are exported the current signal of 4～20mA through after amplifying, superpose, nursing one's health, and are transported to computer processor 5 by the current signal shielded cable.Pulsed velometer 7 is used to measure the speed of travelling belt, and the pulse signal of generation is connected to computer processor 5 via pulse signal shielded cable 6.Computer processor 5 calculates the mass flow data after treatment with weight signal and rate signal.
