Description
Technical field
The invention belongs to the technical field of mass transport.
Background technology
Feedway is used for transported material, and by workpiece along being delivered to next operation, but the weight of some workpiece detects one of its whether standard compliant index, therefore needs to weigh it while transport.When conveying is the material of particulate species, when weighing, as exceeded the weight of regulation, needs unnecessary rejecting.
But existing meausring apparatus is all the electronic balance structure adopted, detected by the weight of erection weight sensor to workpiece in lane of traffic, but first will be considered that actual working environment residing for sensor (is not such as placed in same pipeline weight sensor signal wire (SW) and forceful electric power power lead and control line with weight sensor, attachment face should be smooth, clean, without any oil film, the existence such as glued membrane), this point is most important to correctly selecting weight sensor, can it be related to sensor and normally work and its safety and service life, and even the reliability of whole weighing apparatus and safety.And the working environment of lane of traffic is usually poor, weight sensor can not be made to be in suitable working environment, therefore weight sensor is easily damaged.And the price of weight sensor costly, the cost manufacturing lane of traffic can be increased.
And the not automatic function of being picked out by unnecessary material of existing meausring apparatus, needs manual operation, is not easy to the production of automation.
Summary of the invention
The invention provides a kind of quantitative conveyer, to solve the problem adopting the perishable and not automatic function of being picked out by unnecessary material of weight sensor on a conveyor.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of quantitative conveyer, comprise base, weighing unit and feed pipe, feed pipe is arranged on base, also comprise bar of weighing, be arranged on the radius stay on base and cramp bar, described weighing unit comprises holding thing plate and being connected to the montant holding longitudinal direction below thing plate of horizontally set, montant is connected to weighs on bar, the weigh middle part of bar is hinged on cramp bar, that weighs bar is provided with Weight box away from the one end of holding thing plate, the side of the other end is provided with metal level, radius stay is near the one end being provided with metal level of bar of weighing, radius stay is provided with coupler body, coupler body is higher than the hinge-point in the middle part of bar of weighing, coupler body slidably connects push rod, push rod can offset with holding thing plate, radius stay is provided with conductive layer towards the one side of bar of weighing, conductive layer is contour with the hinge-point in the middle part of bar of weighing.
Herein, the weigh side of bar refers to face parallel with bar plane of rotation of weighing on bar of weighing.
Principle of the present invention is: when one end that bar of weighing is provided with metal level is higher than hinge-point in the middle part of heavy bar, illustrate that the material held on thing plate is overweight, can rise in one end that bar of weighing is provided with metal level, thus by the push rod jack-up on radius stay, push rod can clash into holding thing plate, under unnecessary material is shaken, until push rod not with hold thing plate and offset.When weighing, bar is horizontal, and illustrates that to hold material on thing plate suitable, the metal level of bar of weighing can with the conductive contact of radius stay, can external motor and push pedal, make metal level, between conductive layer and motor, form C/LOOP, material is pushed in feed pipe.
Compared with prior art, the invention has the advantages that: hold thing plate and form a lever construction with bar of weighing, judge whether the weight of workpiece meets the requirements by the position of bar of weighing.When bar of weighing is in correct position, the metal level of weighing on bar is understood and radius stay conductive layers make contact, can connect outward motor by mass transport to next process.When one end that bar of weighing is provided with metal level is higher, automatically unnecessary material can be picked out in the mode of vibration and hold outside thing plate.Present invention employs machinery mode, as weight sensor, requirement higher need not be had to working environment, and of the present invention draw materials comparatively common and cheap, lower relative to weight sensor cost.And can automatically be picked out by unnecessary material holds outside thing plate, manually need not carry out picking out of unnecessary material, be convenient to automated production.
Further, described Weight box is provided with lid, prevents counterweight from dropping out in Weight box.
Further, described lid is hinged on Weight box, prevents lid from losing.
Further, also comprise extension spring, one end of extension spring is connected with push rod, and the other end is connected with coupler body, is convenient to push rod and is returned to initial position.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the structural representation of the meausring apparatus embodiment in lane of traffic of the present invention.
Detailed description of the invention
Reference numeral in Figure of description comprises: base 1, bar 2 of weighing, feed pipe 3, radius stay 4, push rod 5, hold thing plate 6, Weight box 7, montant 8, coupler body 9.
As shown in Figure 1, a kind of quantitative conveyer in the present embodiment, comprises base 1, weighing unit, feed pipe 3, bar 2 of weighing, extension spring, is arranged on radius stay 4 on base 1 and cramp bar.Feed pipe 3 is arranged on base 1, and described weighing unit comprises holding thing plate 6 and being connected to the montant 8 holding longitudinal direction below thing plate 6 of horizontally set, and montant 8 is connected to weighs on bar 2.The weigh middle part of bar 2 is hinged on cramp bar, bar 2 of weighing be provided with Weight box 7 away from the left end holding thing plate 6, Weight box 7 is hinged with lid, and the side of bar 2 right-hand member of weighing is provided with metal level.Radius stay 4 is near the right-hand member of bar 2 of weighing, and radius stay 4 is provided with coupler body 9, and coupler body 9, higher than the hinge-point in the middle part of bar 2 of weighing, coupler body 9 slidably connects push rod 5, and push rod 5 can offset with holding thing plate 6, and one end of extension spring is connected with push rod 5, and the other end is connected with coupler body 9.Radius stay 4 is provided with conductive layer towards the one side of bar 2 of weighing, and conductive layer is contour with the hinge-point in the middle part of bar 2 of weighing.
When this structure uses, the counterweight of approrpiate wts need be put in Weight box 7, need necessary electromotor and push rod, when metal level and conductive layers make contact, metal level, form C/LOOP between conductive layer and motor, the material held on thing plate 6 pushes in feed pipe 3 by electric opportunity driven push rod.
When the weight of material exceedes predetermined weight, the right-hand member of bar 2 of weighing can rise, bar 2 of weighing can drive push rod 5 to rise, push rod 5 can with hold thing plate 6 and offset, push rod 5 and hold after thing plate 6 offsets, can decline, weight as now material still exceedes predetermined weight, push rod 5 can continue to rise, and declines, the weight standard until weight conforms with the regulations.
When the weight of material conforms with the regulations weight standard, metal level and conductive layers make contact, drive push rod to be pushed in feed pipe 3 by material.
Lid is hinged on Weight box 7, prevents lid from losing.One end of extension spring is connected with push rod 5, and the other end is connected with coupler body 9, is convenient to push rod 5 and is returned to initial position.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
