Description
?
Technical field:
The present invention relates generally to crawler type color selector technical field, relates in particular to a kind of device for transporting objects that is used for the crawler type color selector.
Background technology:
The characteristics of crawler type color selector are the materials that can not sort to common color selector institute, adopt the feeding of load-transfer device driving device, and material is when leaving load-transfer device, because action of inertia is dished out with parabolic path, entering color selector separation system sorts.In the color selector separation system; Photodetection system at first detects and is differentiated by judgement system being in material in the dropping process; When judgement system judges that this material particles belongs to heterochromatic (nonconformity material) needs rejecting; Control system can be sent instruction to the spray valve that the below is positioned at the perpendicular parallel with the load-transfer device sense of motion, and the spray valve is rejected heterochromatic grain through high pressure gas.In order to guarantee that look selects effect, require the path of motion of material to be in the perpendicular parallel, to guarantee that can be positioned at this perpendicular inner nozzle of below after heterochromatic grain comes to light rejects with the load-transfer device sense of motion.
But; Because the out-of-shape of material; The running orbit of material is not in the perpendicular parallel with the load-transfer device sense of motion; This just caused the heterochromatic grain that in this plane, is detected because go to other planes not by below the spray valve that is in this plane reject, and the qualified material other planes in is disallowable because go to this plane, this directly has influence on two most important indexs of color selector: precision of color separation and take ratio out of.Cause the reason of above-mentioned adverse consequences to be, drop to moment of load-transfer device at material, the load-transfer device of uniform movement is applied to the tangential velocity of material one horizontal direction; Cause material unstability and rolling backward on load-transfer device; Because the out-of-shape of material, material has produced the componental movement vertical with the load-transfer device sense of motion in the process of rolling, and its whereabouts track when leaving load-transfer device does not have to remain in the perpendicular parallel with running direction of conveyor belt; This material can not be by correct sorting after getting into the color selector separation system; That promptly should reject is not disallowable, and should not reject disallowable, thereby influenced precision of color separation and taken ratio out of with having strengthened.
To above problem, existing solution has two kinds: one, the length of lengthening material conveying track; Two, between vibrations feed appliance and load-transfer device, add arc.
The purpose of first kind of scheme is the contact time that prolongs material and load-transfer device; Utilize friction force between load-transfer device and the material that material is reached and load-transfer device between static relatively; And then guarantee that material running orbit when track ends leaves is in the perpendicular parallel with running direction of conveyor belt, improve precision of color separation, reduce and take ratio out of.But this solution exists significantly advancing the track and load-transfer device length, takes up room, increases the drawback of cost.
Second kind of scheme is to utilize gravitional force to change into kinetic energy theory; The material that is fallen by the hopper that shakes makes material form the speed of a horizontal direction through on arc, sliding, and regulates the size of arc and the height of landing, makes this horizontal velocity approach the linear velocity of load-transfer device; When getting into load-transfer device; The tangential velocity that is applied to material one horizontal direction with load-transfer device reaches relative equilibrium, makes material and load-transfer device reach static relatively fast, thereby realizes that material keeps relative stability on load-transfer device.But this kind method has certain limitation, is affected for the sliding of moist, flat its arc of material, cause accumulation in the arc lower end easily, and the speed of sliding for its arc of difform material also has certain difference.
In addition, the size of arc and landing height adjustment are inconvenient, need make corresponding arc according to the difference of the shape of different material, friction coefficient etc., this spare part quantity that has just increased arc with change frequency.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of prior art; A kind of device for transporting objects that is used for the crawler type color selector is provided; It falls the material that gets into the color selector separation system in the perpendicular parallel with running direction of conveyor belt, solved because of the inconsistent precision of color separation that causes of mass transport track not high with take out of than a high difficult problem.

A kind of device for transporting objects that is used for the crawler type color selector is characterized in that: the one-level feedway is identical with the speed of transmission of two-stage conveying device, and the discharge end height of one-level feedway is higher than two-stage conveying device feed end height.
A kind of device for transporting objects that is used for the crawler type color selector is characterized in that: be arranged at intervals with the convex tendon or the groove that are parallel to running direction of conveyor belt on the load-transfer device of said one-level feedway.
The present invention changes the feeding of original one-part form load-transfer device the feeding of into two sectional type load-transfer device.During the work of crawler type color selector, material at first drops on the one-level feedway through the hopper that shakes, and arrives the two-stage conveying device through the transmission of one-level feedway, dishes out from the discharge end of two-stage conveying device at last.
The main effect of one-level feedway is that the material that drops on this load-transfer device is quickened, and makes its speed reach the running velocity of two-stage conveying device.
Material after the discharge end discharging of one-level feedway, material because of inertia dropping on the two-stage conveying device with the identical speed of two-stage conveying device speed of transmission, and static relatively with the maintenance of two-stage conveying device rapidly.Like this, when material was dished out from two-stage conveying device discharge end, its running orbit can remain in the perpendicular parallel with running direction of conveyor belt, and then had improved precision of color separation, reduced and taken ratio out of.
In order to make material can on the one-level feedway, be rapidly accelerated to the running velocity of two-stage conveying device, the present invention adopts the big one-level feedway of friction coefficient, and on its load-transfer device, is arranged at intervals with convex tendon or the groove that is parallel to running direction of conveyor belt.So, material is after falling on the one-level feedway, because receive the restriction of convex tendon on the load-transfer device or groove; The componental movement vertical with running direction of conveyor belt eliminated rapidly; And because the friction coefficient of load-transfer device is big, material can reach rapidly and the static relatively state of load-transfer device, like this; When material was dished out by the one-level feedway, its running orbit can remain in the perpendicular parallel with running direction of conveyor belt.
Between one-level feedway and two-stage conveying device; Because there is certain clearance, the foreign material of light specific gravities such as dust, cogongrass fall from the gap because receiving the relative big resistance of its quality of air, thereby have reduced the foreign material that get into separation system; Improve the precision of look choosing to a certain extent; Simultaneously, also reduced dust and checked colors and select the influence of electromechanical equipment, reduced rate of breakdown, prolonged service life of equipment.
In addition, because the restriction of crawler type color selector separation chamber structure space, the diameter of cylinder of discharge end is less in the two-stage conveying device, and promptly the turn radius of load-transfer device is less, and this has just caused the load-transfer device life-span significantly to lower.Because after the present invention adopts the two sectional type structure; The diameter of cylinder of one-level feedway can not receive the influence of separation chamber's space size; Can freely select the diameter of cylinder size; The size of diameter of cylinder designs with the minimum diameter that is not less than this load-transfer device and requires, thereby has improved greatly the service life of one-level feedway.Compare with original one-part form mode of movement, what the two sectional type mode of movement need be changed according to original frequency only is the two-stage conveying device, and the replacing frequency of one-level feedway load-transfer device then reduces greatly, and then has reduced the maintenance cost of equipment.
