Specific embodiment
The technical solution of the utility model is illustrated with reference to the accompanying drawings and embodiments, so that those skilled in the art
Be clearly understood that, but including and be not limited to following embodiments, equivalent technical solution is still within the protection scope of this case.
Embodiment one
Such as main view, top view and the axis side view that Fig. 2, Fig. 3, Fig. 4 are weighing-appliance, including pilot unit, rise
Unit, weighing unit, blocking unit and feedboard 5, body plate 2 and base anchor 1 drop, and the precision needed due to weighing data will be
Within 5%, so base anchor 1 and body plate 2 are fixed with anchoring bolt, to prevent generating vibration.
Most importantly weighing unit in whole equipment, since the error of whole system and the quantity of weighing sensor are into
Inverse relation cannot support entire weighing platform 3 using a weighing sensor, and weighing sensor is using two beam type sensings
Device in order to make weighing sensor 9 by the effect of single power and the moment of flexure of very small part, therefore is equipped with V-type on weighing platform 3
Block 4, the effect of V-block 4 are exactly to keep toilet paper 10 placed in the middle on weighing platform 3.The distribution of weighing sensor 9 is also wanted simultaneously
It asks, weighing platform 3 and toilet paper 10 is simplified to beam stress simply and are uniformly distributed, then the force diagram of beam and bending moment diagram simply is as schemed
Shown in 1, two o'clock is supported at the 1/4 of beam simply and at 3/4, and beam institute bending moment simply is minimum, moment of flexure maximum be at fulcrum,
The amount of deflection of beam is also minimum value at this time, the stress size at supporting point be also it is the same, Impact direction is also consistent.Or it selects
Strain gauge transducer, weighing sensor 9 has deformation under the effect of gravity, since weighing sensor 9 and weighing platform 3 are rigid
Property connection, therefore the layout direction of weighing sensor 9 is consistent, and the deformation direction of such weighing sensor 9 is also consistent, weighing
Influence of 3 rigidity of platform to weighing sensor 9 will be eliminated.
As shown in Fig. 2, toilet paper is rolled out by end sealing machine outlet, entered on weighing platform by feedboard 5, weighing-appliance work
Make the cylinder 7 that state initial position is blocking unit and be in stretching state, the cylinder 15 of lifting unit is also stretching state, guiding
The cylinder 11 of unit is to retract, and the photoelectric sensor above weighing-appliance has detected toilet paper, then lifting unit and resistance
The cylinder of gear unit starts to retract, and after weighing sensor 9 obtains a stationary value, can analyze weight, if weight
Setting value is had exceeded, then the signal adjusted to mono- joint number of rewinding machine PLC.Specifically:
Toilet paper is rolled on lifting unit supporting plate 13 by feedboard 5, the photoelectric sensor detection above equipment to be weighed
To there is toilet paper, then photoelectric sensor can input a digital quantity signal to the PLC of weighing-appliance, and PLC is by operation at this time
Reason, then output signal obtains the electromagnetic valve coil of lifting unit cylinder electric, to control the retraction of lifting unit cylinder 15.
As shown in figure 4, being weighing state at this time, after weighing sensor 9 obtains stationary value, lifting unit drags paper roll
It rises, at this time the cylinder 7 or retracted mode of blocking unit, therefore paper roll can be rolled out from lifting unit, be waited above lifting units
Sensor can't detect paper roll, and the cylinder 7 of blocking unit will be stretched out, be weighed to next paper roll, so recycle repeatedly.
Specifically:
Toilet paper is fallen completely on weighing platform 3, and display instrument shows the weight of toilet paper at this time, and weighing sensor obtains
The final weight of toilet paper can be compared with the specification weight of the toilet paper currently produced.Such as currently used body paper grammes per square metre
It is 15g/m2, base paper web width is 2860mm, and the toilet paper specification currently produced is diameter 80mm length 155mm, three-ply paper,
The length of every section paper is the toilet paper of 200 sections ability production department 80mm diameter needed for 115mm event, and the weight of this specification is 160 grams.
According to national regulation, the error of hygienic paper weight is within 5%, therefore the hygienic paper weight of production department is 160 ± 8 grams.2860mm
The paper web of width can produce the toilet paper of 18 155mm length, and the length of waste material end to end remaining at this time is 35mm, due to production
Middle health paper weight is random fluctuation, and the weight of the toilet paper of each section is 14.8 grams (15*0.155*2.86*3).If
The weight that weighing-appliance detects does not adjust within 1 times of every section health paper weight with required specification weight error, in 1-2
A section is adjusted within times, two sections are adjusted within 2-3 times, and so on.Weighing-appliance feeds back the joint number signal for needing to adjust
To the PLC of rewinding machine, the joint number of rewinding machine will be adjusted.
The specification for the toilet paper being able to satisfy due to the utility model is diameter 60mm to 140mm, random length, largest production
Speed is 20/min, and as 20/min of speed of production >, weighing-appliance carries out interval weighing to paper roll.When lifting unit falls
Paper roll is put into weighing platform 3 to weigh, the cylinder 11 of pilot unit can then stretch out, next paper roll smoothly seen off, to
Detection finishes, and the cylinder 11 of guiding mechanism can then retract.For safety, the cylinder of elevating mechanism and guiding mechanism has one mutually
The design of lock, avoids lifting unit from interfering with pilot unit.
The speed of production that weighing-appliance is met by is 20/min, and the speed of rewinding machine is lower than 20/min, weighing-appliance
It can weigh to each toilet paper of rewinding, record the weight data of each toilet paper.Weighing sensor
To time of data is stablized within 0.5s, so the magnetism after the cylinder 15 of lifting unit is retracted to lowest order, on cylinder
As soon as switch can export a signal, recur after 0.5s stretching with unifying time delay module and can control lifting unit cylinder, general
Toilet paper is removed from weighing platform.
If the speed of rewinding machine is higher than 20/min, weighing-appliance just needs to weigh to toilet paper interval at this time, works as lifting
After the cylinder 15 of unit is fully retracted, pilot unit cylinder 11 can then stretch out, and the guide plate 12 on guide cylinder guides health
Paper is fallen into storage paper frame.After subject-oriented unit cylinder 11 retracts, the gas circuit of lifting unit will be connected again, at this time lifting unit
Cylinder 15 can stretch out, toilet paper is removed from weighing platform.Such mechanism will carry out stable weight inspection to toilet paper
It surveys.
Embodiment two
On the basis of example 1, lifting unit cylinder 15 has a gas circuit Cushioning Design, in order to realize that cylinder has
Two kinds of speed of high low speed, such toilet paper, which can steadily be fallen in, will not generate vibration on weighing platform, paper can be allowed finally to delay
Slow falls on weighing platform 3, reduces detection time and improves detection accuracy.
Embodiment three
On the basis of example 1, so weighing unit cylinder 15 can there are three sensor, lowest order and highest orders point
There is not a magnetic switch, the very good position for touching weighing platform 3 of toilet paper is fallen under cylinder a magnetic switch, this
The effect of magnetic switch is to change the movement velocity of cylinder for switching gas circuit.Realize that the movement of weighing unit cylinder is divided into two
A part just touches weighing platform from cylinder range to toilet paper, this section is high speed apart from cylinder, and it is flat to enter weighing
It is low speed after platform.
