Description

Weight sorts scale

Technical field

It the utility model is related to automatic weighting and sort field, more particularly to weight detecting scale and weight grading scale.

Background technology

In the productions such as food, medicine, chemical product and packaging process, it is necessary to by production standard and metrological legislation to the weight of product Amount is checked and overweight and ultralight product is picked out that what is also had needs the weight progress range by product, this A little processes are required for weight detecting scale and weight grading scale.

When weight detecting scale and weight grading scale work, object is usually that object is served one by one by charging belt conveyer Scale is examined again；It is usually dynamic duty to examine scale again, and object moves, while carrying out weight detecting, i.e. the weight detecting Ministry of worker is most Also using belt conveyor conveying object, the moiety by weight detection Ministry of worker also is moved on to using tilting slide plate using the potential energy of object Object；To ensure production and detection efficiency, general object can all remove the detection Ministry of worker with certain speed；One after the completion of detection As be that object is moved on on follow-up belt conveyor, object to be detected by measured weight in fact and is sorted by standard selected thereon Not, rejecting, go-on-go or classification.At present, reject, go-on-go or classification mechanism are usually to add blow-out nozzle or rotation on belt conveyer Driving lever or line handspike, or using vacuum slot, or directly upset or hoisting belts conveyer.They have various ask Topic：

Blow-out nozzle：Noise is big, to ultralight, ultra-thin object, such as paper, facial mask, the especially empty pack of small pack, rejects effect Fruit is poor, otherwise fixed object is usually blown, otherwise object disorderly flies, can not fall into material-receiving device.May discontinuously occur not on production line Certified products, defective work can also continuously occur.If continuous unqualified, the noise of air blowing will very disturb people, and sometimes Air pressure is caused to decline so that can not normal work.

Rotate driving lever：Also referred to as swing rod, the rougher object of heavy objects or its bottom surface is promoted to wear belt；High speed motion Push rod or swing rod can damage weighed object；Be not suitable for ultra-thin object, such as paper, facial mask, small empty pack, easily ultra-thin object Folder is got lodged between lever and belt conveyor.

Line handspike：Problem with rotating driving lever, also continuous substandard product by when, push rod will move back and forth Make, noise will very disturb people, and sometimes results in air pressure and decline so that can not normal work.

Vacuum slot：Quasi- mobile object, the control cost that object is removed again height are inhaled, resetting time is grown, and efficiency is low.

Belt conveyor or hoisting belts conveyer are overturn by axle of weighing unit discharging opening：Manufacturing cost is high, upset or The big loads such as hoisting belts conveyer cause aerodynamic noise big.

In addition, belt conveyor takes, production space of lines is big, and dismounting is pretty troublesome, and belt cleaning is inconvenient, motor and The waterproof cost of swivel bearing is high.Further, nozzle, push rod, swing rod can only all carry out the go-on-go of 2 ranks.

It can be seen that weight sort scale prior art be respectively provided with complicated, manufacturing cost is high, cleaning is difficult, work noise is big, Be not suitable for frivolous object sort rejecting, poor reliability, belt conveyor is fragile, space-consuming is big etc., and rejecting sorts asking for mechanism Topic.

Utility model content

Researcher utilizes belt conveyor always when solution weight sorts scale and sorts the existing issue of technology at present Carry out mobile object and carry out rejecting sorting operation thereon.All do not notice or ignore always the efficiency of the production line of factory With speed more and more higher, object already has the enough inertia moved along production line direction, sufficiently small in resistance In the case of can be along production line persistent movement for quite a long time and a considerably long segment distance.Known, smooth slide plate Or guide rail etc., object long range can be made, slided for a long time.

For the deficiency of the prior art of the rejecting of weight detecting scale and weight grading scale, go-on-go or classification mechanism, sheet Utility model using object remove weighing unit still when with certain speed, with certain movement inertia the characteristics of, proposition A kind of mechanism that sorts has the characteristics that simple in construction, manufacturing cost is low, the easy weight of cleaning sorts scale.

The application is adopted the technical scheme that：A kind of weight sorts scale, including the first frame and switch board, feed material list Member, the weighing unit that is arranged in the first frame, in addition to it is at least one sort mechanism, each sort mechanism and be correspondingly arranged at least One splicing unit, it is characterized in that：Sorting mechanism includes the second frame, slide rail, and upper surface, the lower surface of slide rail are smooth Slideway, slide rail are connected with the second frame by rotating shaft, and turnover driving mechanism driving slide rail is also set up in the second frame around the shaft Rotate, feeding unit material, weighing unit, turnover driving mechanism electrically connect with switch board respectively.

Turnover driving mechanism driving slide rail upset, slide rail can at least rest on two positions.First static state of slide rail Position integrates with for the upper surface of slide rail with object supplied materials direction, and optimal is parallel docking；Object can be slipped over from slide rail upper surface, fallen Enter the splicing unit at slide rail rear.Second static position of slide rail is met to object supplied materials direction for the lower surface of slide rail, changed Object follow-up operation direction；The lower surface of slide rail and object traffic direction are in that included angle A is acute angle less than 45 °, can make inclination Slide rail lower surface reduce shock and damage to object, the object that guiding is head-on brought falls into the splicing list of the slide rail back lower place Member.

Turnover driving mechanism can drive slide rail to be at least foregoing 2 static positions, real using the motional inertia of object Now sort purpose.

Weight detecting screening scale only needs one to sort mechanism, and weight grading scale can select multiple to sort mechanism as requested With the splicing unit of respective amount.Weighing unit can be that belt conveyor is installed on weighing sensor, i.e. conventional inspection scale again； Can also be installation hard slide plate, i.e., the slide plate scale weighed in object taxiing procedures, the weighing platform of slide plate scale on weighing sensor Upper surface can be horizontal, can also be tilted down along object traffic direction.Feeding unit material may be mounted in the first frame, also may be used There is independent rack with oneself, can also directly be the discharging opening of conveyer on production line or packing machine, it is therefore an objective to feeding and handle Spacing between object is pulled open, and makes object sequentially weighing platform successively；During for weighing precision and less demanding vibration control, second Frame and the first frame are combined into one.

The specific feature of this programme also has, and in weighing unit and sorts and is additionally provided with delay protective unit between mechanism, prolongs When protective unit upper surface object input at position be slightly less than weighing unit object exit position, delay protection is single The position in the object exit of first upper surface is slightly above the position at the object input of slide rail upper surface.

On the one hand, for many high speed dynamic weighing control systems, when object to be detected removes weighing unit, otherwise do not have also Obtain weight test result, signal can not be sent to turnover driving mechanism, otherwise it have issued drive signal but overturn driving Mechanism can not allow slide rail to be in correct position in time；So object needs certain time-delay to be selected after removing weighing unit Do not move work.On the other hand, the range of weighing unit is limited, to ensure the quick response of turnover driving mechanism, turnover driving mechanism Strength it is all very big；Do not pressed due to object and conveyer is arrived on specific length interval, or occurred wrapping without such as sky of identification, even wrap The problems such as, it may cause drive signal that switch board provides and wrong section occurs in the beat of object movement, during slide rail closure or openness Object may be clamped, may not only cause damage of product, it is most important that also results in the damage of precision overload, the skin of weighing unit Band infringement.

By weighing unit and sort among mechanism set transition delay protective unit, dexterously solve above-mentioned two Individual problem.The length of delay protective unit should be greater than object and remove the speed of weighing unit and weighing unit be removed since the object At the time of play the product that switch board controls turnover driving mechanism at the time of institute's interlude section in place according to weighing results.Control Turnover driving mechanism processed in place at the time of it is more late, the length for the protective unit that is delayed is longer；As weighing results in object start to move Go out before weighing platform just obtained and turnover driving mechanism in place also quickly, control turnover driving mechanism in place at the time of will be earlier than At the time of object starts to remove weighing unit, the length can for the protective unit that is delayed is not required to delay function, need to only prevented close to zero Protective function is sufficiently strong, and weighing platform can be protected not damaged just by slide rail malfunction.The weighing platform of high speed go-on-go scale is all very short, weight result Drawn mostly after object goes out weighing platform, during using the utility model, be typically necessary setting delay protective unit.

Delay protective unit is hard plate, and the upper surface of hard plate is smooth slideway.

Object is weighed for most of, its surface is all very smooth, and the line speed of production line is also quickly, by title thing Body all has certain speed and inertia.So weighed object can be in smooth slideway sliding way certain time；Slideway can be with A kind of means as delay.Just in case wrong section occur in drive signal and the beat of object movement, the slideway of hard will not be because sorting The quick of the slide rail of mechanism is hit and damaged easily energetically.

Delay protective unit is belt conveyor, and belt conveyor electrically connects with switch board.

For sliding it is bad be weighed object, or line speed it is relatively low be weighed object, it is necessary to using belt Conveyer is delayed, and the infringement not brought using the accurate weighing unit of its protection by the slide rail malfunction for sorting mechanism.

Feeding unit material, weighing unit, sort mechanism and be sequentially arranged, the first static position, i.e. upset driving are parked in slide rail Mechanism drives slide rail upper surface and object supplied materials direction to integrate with, object from slide rail upper surface it is smooth slip over position when, on slide rail Position at the object input of surface is slightly below the position in weighing unit object exit.

For the weighing instrument of ultrahigh speed reaction, or the weighing unit that weighing platform is longer（Object is weighed when removing weighing platform table top As a result just out and turnover driving mechanism, slide rail have been sent to also in place）, cunning can be directly connect behind weighing unit Rail, centre are not provided with the protective unit that is delayed.

The slideway of slide rail upper surface is prismatic structure.

The sticky object of the object special to some surface configurations and surface, prismatic structure can improve sliding and reduce Abrasion to slide rail upper surface.Slide rail upper surface can be smooth plane or along object traffic direction prism, U grooves or the prism-shaped groove of V grooves or W grooves or other special shapes, can also be row's side-by-side parallel along object traffic direction Smooth shaft.

The upper surface of slide rail and lower surface are plane.

It is typically chosen and meets that the desired object that is weighed is slipped in the upper surface of slide rail into the splicing list for connecing qualified products Member, the undesirable lower surface for head-on rushing at slide rail fall into the splicing unit of undesirable product, and splicing unit can be with It is charging basket, belt conveyor can also be made.Structure is most simple, manufacturing cost is minimum, the slide rail of cleaning most convenient is flat board bending Structure.Rush at the whereabouts posture for being weighed object of slide rail lower surface for control, the lower surface of slide rail and upper surface can with it is parallel, Can also be not parallel, it can also be parabolic shape；For example, slide rail upper surface is plane slideway structure, lower surface moves ahead along object Direction is parabola slideway structure.

Turnover driving mechanism is cylinder, and slide rail jointed shaft is provided with slide rail, and the second frame is provided with the second frame and is cut with scissors Spindle, one end and the slide rail of cylinder are hinged axis connection, the other end and the second frame and are hinged axis connection.

Turnover driving mechanism is motor, and motor is fixed in the second frame, and rotating shaft and slide rail are rigidly connected, motor and rotating shaft Connection, motor drive slide rail to overturn by rotating shaft.

Turnover driving mechanism can also be electric pushrod or electromagnetism push rod, electric pushrod or electromagnetism push rod and slide rail side Slide rail beyond rotating shaft is hinged axis connection；Turnover driving mechanism can also be motor or Pneumatic rotary element, motor or pneumatic rotation The rotating shaft for turning element with slide rail side is connected.

Weighing unit is tilted-putted slide plate scale, and feeding unit material, weighing unit, be delayed protective unit, slide rail cloth successively Put, feeding unit material is parallel with weighing unit relatively, tilts down.

The utility model also includes：Photoelectric detection system is set sorting device front end certain distance, moved according to object Speed, object length and Photoelectric Detection moment confirm to be weighed the particular location of object, further confirms that turnover driving mechanism Action.Weight grading scale can according to the response of multiple photoelectric detection systems for sorting device front end to determine when, which Turnover driving mechanism acts.

A kind of weight of the present utility model sorts scale, compared with prior art, while has beneficial effect prominent as follows：

First, sort that mechanism is simple in construction, manufacturing cost is low, cleaning is easy.

2nd, the action of sweeping the floor of no swing rod or push rod, it is particularly suitable for the light, weight of thin product and sorts.

3rd, hard slide rail is more more robust than belt conveyor, sorts that device longevity is higher, reliability is higher.

4th, in light weight, slide rail that size is small is driven, sorts that action is quieter, and aerodynamic noise is small.

5th, inexpensive multipass sort, a set of mechanism that sorts can realize 3 grades or more level sortings：The lower surface of slide rail meet to Object supplied materials direction, the drop point of object can be controlled well.Control slide rail the lower surface elevation angle, can both allow different shape, Falling into for the object of friction speed is a little identical, can also allow same type objects（By different weight scope）Fall into a difference.

6th, sort that mechanism space-consuming size is very small, suitable for compact production space of lines：

For soft thin object, exemplified by overturning belt conveyor rejecting mechanism, when production line belt speed is close to 0, turn over The half for the length that the length for turning belt conveyor is at least greater than object could allow object center of gravity to tilt downwards, and this practicality It is new needed for length be only can be stopped when slide rail lower surface is dug object required slide rail height, only need to allow slide rail lower surface with Object supplied materials direction is in the acute angle that included angle A is less than 45 °；When production line belt speed is very high, belt conveyor is overturn Length need to grow very much, parallel rearmounted splicing unit otherwise will be bumped against during object fall.And length needed for the utility model is still Object length so is much smaller than, need to only allow slide rail lower surface with object supplied materials direction in the acute angle less than 45 °.

By taking swing rod rejecting mechanism as an example, belt conveyor length is at least greater than object length, is also greater than oscillating bar length In maximum pendulum angle in the projection of object traffic direction.

By taking push rod rejecting mechanism, air-blowing, vacuum slot, hoisting belts conveyer as an example, belt conveyor length at least will More than object length.

7th, go-on-go is more efficient：

1st, with line speed 60m/min, object length 80mm height 10mm, sort belt conveyor roller behind mechanism For for overturning belt conveyor rejecting mechanism, object front end upper surface falls on roller lower edge needs exemplified by the diameter 40mm of cylinder Time is about 0.1s, and object length translation takes 0.08s, and the time that object is integrally fallen under roller amounts to 0.18s；And this reality Slide rail lower surface is all fallen on novel object only needs 0.08s.Object is shorter, two schemes to sort efficiency difference bigger.

If the 2, defective work continuously occurs in production line, slide rail need to only be maintained at a static position；And straight line pushes away Bar or air-blowing mode then need perseveration.

In a word, above-mentioned all advantages greatly extend the scope of application that weight sorts scale.
