Description
Technical field
The utility model relates to packing scale and feeding gate mechanism thereof.
Background technology
At present feeding gate adopts cylinder to control opening and closing of bin gate at the bottom of the awl that uses in the packing scale, realizes thick, smart two-stage feed according to the value of feedback of LOAD CELLS real-time sampling.Bin gate action is subjected to the cylinder stroke limitation, opens fixing aperture in can only the weighing process to realize thick, smart two-stage feed, is subjected to the material shock effect, prevent that " material overshoot " phenomenon from taking place, thick reinforced bin gate aperture can not be excessive, and the finishing material value of setting is bigger, influences package speed; Simultaneously because aperture is fixed, and it is also relatively poor that the pattern of action single caused the comformability of different material, weighing precision is relatively poor.
The utility model content
The purpose of this utility model is to provide a kind of packing scale and servo-type awl end feeding gate mechanism thereof, its wide application range of material.
For realizing the packing scale servo-type awl end feeding gate mechanism of described purpose, be characterized in, comprise servomotor, transmission device and awl bed material door, transmission device comprises rotating element and the olinear motion part that couples mutually, rotating element and servomotor couple, olinear motion part and awl bed material door couple, so that the rotation of servomotor is converted to the movement of awl bed material door.
For realizing the packing scale of described purpose, comprise feeding warehouse and awl end feeding gate mechanism, be characterized in, feeding gate mechanism comprises pulser, servomotor, transmission device and awl bed material door at the bottom of this awl, transmission device comprises rotating element and the olinear motion part that couples mutually, rotating element and servomotor couple, and olinear motion part and awl bed material door couple, so that the rotation of servomotor is converted to the movement of awl bed material door; This pulser is exported a plurality of impulse singlas to servomotor, so that between this awl bed material door and the feeding warehouse multiple aperture is arranged.
In the preferred embodiment of the present utility model, described mechanism also comprises guide holder, and guide holder can move up and down along the guide rail on the feeding warehouse, and the olinear motion part of transmission device is captiveed joint with guide holder.
In the preferred embodiment of the present utility model, described transmission device is nut screw mechanism, synchronous pulley mechanism or flute profile chain-wheel mechanism.
In the preferred embodiment of the present utility model, this mechanism also comprises near switch, is installed in the moving direction of guide holder.
In the preferred embodiment of the present utility model, matching relationship between the impulse singla of described pulser, servomotor, transmission device, the awl bed material door is: hoisting speed and the material falling speed in the feeding warehouse of awl bed material door are linear, awl bed material door is up to a closed conditional curve by aperture and is matched with in the packing material from zero incremental rate curve to target weight so that do not do in the whole blanking process of awl bed material door pause and also when bin gate is closed in the packaging bag weight of material just in time reach target weight.
The characteristic of utilizing servomotor just can be controlled awl bed material door by different pulse output and stop in different positions, realizes the variety of bin gate aperture, and raising is to the applicability of different material.
Aforementioned purpose of the present utility model, characteristics and advantage will describe in detail in embodiment described later.
Description of drawings
Fig. 1 is the front view of packing scale.
Fig. 2 is the section-drawing along A-A line among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, packing scale comprises servo-type awl end feeding gate mechanism, and it comprises servomotor 1, transmission device 2 and awl bed material door 6.
Utilize leading screw helical pitch (a) with the rotation number of turns (n) of servomotor 1 and vertical direction miles of relative movement (S) generation fixed relationship: the S=an of awl bed material door 6, make awl bed material door 6 and feeding warehouse 5 keep suitable aperture to satisfy the blanking demand by the rotating cycle of controlling servomotor 1.
Therefore, in embodiment of the present utility model, packing scale also comprises pulser (not illustrating in the drawings), provide impulse singla to servomotor 1 by it, and the characteristic of utilizing servomotor 1 just can be controlled awl bed material door 6 by different pulse parameter settings and stops in different positions, realize the variety of bin gate aperture, improve the applicability to different material.Utilize the variety of bin gate aperture simultaneously, realize multistage flexible feed: in an actuation cycle process, utilize the multiple aperture of bin gate that material is done material and do the classification buffered, solve under " material overshoot " prerequisite at actv., improved running velocity.Further, matching relationship of respectively forming in the packing scale is that hoisting speed and the material falling speed of servomotor control bin gate is linear, bore the bed material door and be matched with the interior material of packing from the zero incremental rate curve that weighs to target by the conditional curve that aperture is up to closure, do not make any pause just changes bin gate by servomotor hoisting speed in the whole blanking process of awl bed material door, when bin gate was closed, weight of material just in time reached target setting weight in the packaging bag.
In a contriver's of the present utility model test, with respect to the technical scheme before improving, the package speed of awl bed material gate-type packing scale be promoted to 300 bags/hour, precision 0.1%, wider to the material applicability simultaneously, different material switches only to be needed when producing can finish the matching operation by the parameter setting.
In other embodiment of the present utility model, transmission device 2 can also replace with synchronous pulley, the flute profile sprocket wheel, and awl bed material door 6 is fixed on synchronous band or the chain by attaching parts, and transmission device 2 also can be other mechanisms that rotation are converted to straight line.
