Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
A kind of online checking weight weigh based on electromagnetic force balance sensor as shown in Figure 1-2, comprisesElectromagnetic force balance sensor 1, frame 2 and be arranged in frame 2 along rectilinear direction successivelyFor sending into the input mechanism 3 of product to be measured, for transmitting the connecting gear of product in the position of weighing4, survey the output mechanism 5 of product and for rejecting bad part eject conveying mechanism 6 for exporting,Connecting gear 4 has the support portion 41 along vertical elastic deformation, electromagnetic force balance sensor 1Be positioned at this 41 belows, support portion, this electromagnetic force balance sensor 1 and rejecting conveying mechanism 6 electricityConnect, the throughput direction of this rejecting conveying mechanism 6 is crossing with the throughput direction of output mechanism 5.
Electromagnetic force balance sensor 1, also claims electromagnetic sensor or magnetoelectric sensor, and it certainlyBody has that precision is high, resolution ratio is high, respond fast characteristic, therefore, and when product introduction to be measured passesSend the support portion 41 of mechanism 4 and occur after elastic strain, the weight of product to be measured can be passedBe handed to electromagnetic force balance sensor 1, then by the accurate detection of electromagnetic force balance sensor 1, justCan obtain accurately the weight of product. Because the weight detecting process of product is at readerIn the running of structure 3, connecting gear 4, output mechanism 5 and rejecting conveying mechanism 6, carry out, therefore, applicable to the weight detecting to product in streamline, production efficiency is higher. ItsIn, reject conveying mechanism 6 crossing with the throughput direction of output mechanism 5, thereby can be quicker,Reject in time substandard products.
For promoting the stability of carrying, this routine input mechanism 3, connecting gear 4 and output machineStructure 5 is the first belt type conveying mechanism, and has respectively conveyer belt, and support portion 41 is biographySend the conveyer belt of mechanism 4, input mechanism 3, connecting gear 4 and output mechanism 5 are along straight line sideTo docking successively.
For in time, effectively reject substandard products, reject conveying mechanism 6 and comprise valve 61, reclaim cover62 and second belt type conveying mechanism 63, valve 61 is fixed on frame 2, the second ribbon conveyersStructure 63 is installed on and reclaims in cover 62, reclaims cover 62 and has the opening relative with valve 61. WhenWhen the weight numerical value that electromagnetic force balance sensor 1 detects and setting value are not inconsistent, will send signal extremelyReject conveying mechanism 6, order about valve 61, the second belt type conveying mechanism 63 operates, with will timeProduct are rejected to reclaiming cover 62.
