For the ease of sorting, personnel are timely and conveniently small by the sorting of the transfer of packages on total pipeline to sorting conveyer belt
Che Shang, shunting pipeline 20 can be respectively set in we between the drive end and total pipeline of each sorting conveyer belt, and is sorting
A package centralised arrangement 201 is arranged in the drive end side of conveyer belt, and shunting pipeline one end is close to corresponding sorting conveyer belt
The package centralised arrangement of drive end side, the other end is close to total conveyer belt, and the controllable shunting pipeline of drive end setting is standby
The control switch switched between state and SHUNT state.When sorting personnel need package, control switch can be pressed, shunting is made
Pipeline enters SHUNT state, shunts pipeline at this time and starts, the package on total pipeline can pass sequentially through shunting pipeline into
Enter to wrap up in centralised arrangement, sorting personnel, which can easily take out of package centralised arrangement, needs the package that sorts.Work as package
When package in centralised arrangement reaches certain amount, sorting personnel can press control switch again, and shunting pipeline is made to switch to
Standby mode, at this time the package on total pipeline continue to move forward.It should be noted that package centralised arrangement can be a top
The material collecting barrel of opening.
For the ease of by the transfer of packages on total pipeline to shunting pipeline, total pipeline of the invention includes several
Along the spaced apart basic transportation section 101 of the length direction of total pipeline and be connected to the basic transportation section of adjacent two it
Between shunting transportation section 102, the quantity for shunting transportation section is consistent with the quantity of sorting conveyer belt.In addition, shunting transportation section is remote
Be rotatablely connected from shunting pipeline side and basic transportation section, to making shunting transportation section tool there are one horizontal feed status and
One switching state rotated down.Preferably, several lateral separation cloth are respectively set on basic transportation section and shunting transportation section
The conveying roller 202 set, conveying roller can be associated with power source by driving belt or transmission chain etc., to make basic transportation section
Roller transport model is constituted with shunting transportation section.Certainly, roller transport model can also be used in shunting pipeline.When shunting transportation section
When in feed status, shunting transportation section is flushed with basic transportation section, and basic transportation section is spliced into one with shunting transportation section at this time
The smooth total pipeline of item is wrapped under the driving of conveying roller and is moved forward successively by basic transportation section and shunting transportation section.
It when pressing control switch when sorting personnel needs acquisition package, shunts pipeline and switches to SHUNT state, at the same time, shunt
The close shunting pipeline side in transportation section enters the switching state tilted down after rotating down.Being wrapped on basic transportation section
It when being moved to the shunting transportation section tilted down, that is, automatically falls on the shunting transportation section tilted down, the package fallen edge again
The shunting pipeline tilted down automatically into package centralised arrangement.When the package in package centralised arrangement reaches a fixed number
When amount, sorting personnel can press control switch again, and shunting pipeline is made to back switch to standby mode, and correspondingly, shunting is defeated
Section is sent to be rotated up to the feed status flushed with basic transportation section, the package on total pipeline can continue to move along, with
Just the shunting of subsequent sorting conveyer belt.It should be noted that respectively independent power source can be used in the conveying roller of shunting transportation section

It is slid to package centralised arrangement from shunting transportation section for the ease of package, we can be below shunting transportation section
One switching support 103 is set, which is sloped downwardly close to the one of shunting pipeline, and angle of inclination and shunting are defeated
Angle of inclination when section being sent to be in switching state is consistent.Several rolling rings 104, the axis side of rolling ring are set on switching support
To, rolling ring rectangular array arrangement consistent with the length direction of total pipeline, formed on switching support several by total defeated
The row of the longitudinal arrangement of line sending, the rolling ring per a line are then arranged along the laterally equidistant of total pipeline, and rolling ring
Height is less than the gap between two neighboring conveying roller on shunting transportation section.When shunting transportation section is swung down to switching state
When, the rolling ring on switching support below is located just at the gap between conveying roller adjacent on shunting transportation section, and
And rolling ring is higher by the conveying roller of the shunting transportation section.In this way, to fall into the shunting tilted down defeated for the package on basic transportation section
When sending in section, package is directly contacted with rolling ring, you can is scrolled down through to shunting pipeline along rolling ring.It is appreciated that
It is that rolling ring can realize rolling friction, therefore, is conducive to the downslide of package.
In order to reduce floor space, as shown in Fig. 5, Fig. 6, Fig. 7, sorting conveyer belt 2 of the invention includes that left and right two is set
The sorting track 23 of the oblong in rack 1 is set, sorting track is located in perpendicular, to make sorting track have up and down
Two above and below the semicircular transfer trajectory 232 of two horizontal rails 231 and the upper and lower two horizontal rail front ends of connection, connection
The semicircular transfer trajectory of horizontal rail rear end.Certainly, the sorting track of two oblongs in left and right should be mutually parallel, so as to
Sort trolley loopy moving on sorting track.In order to ensure sorting trolley remains horizontality on sorting track, I
Need to make the sorting track in left side to arrange rearward, the forward arrangement of sorting track on right side, before being formed to two sorting tracks
Dislocation arrangement afterwards.In addition, as shown in figure 8, sorting the right side front of trolley rotatably arranged with advancing slip kinetoplast 31, advancing slip kinetoplast
It is slidably connected on the sorting track on right side, rear end is slided rotatably arranged with rear slide mass 32, rear slide mass on the left of sorting trolley
It is dynamic to be connected on the sorting track in left side, and the distance between forward and backward slide mass in the longitudinal direction is equal to two sorting rails
The dislocation distance in road.Using drive end as rear side in the present embodiment, driven end is front side, and correspondingly determines left and right side.
When sorting trolley moves forward in the horizontal rail on upper layer, the axis of the forward and backward slide mass of sorting trolley both sides
Line is in horizontality, and arranges in left-right direction, that is to say, that and the axis holding of forward and backward slide mass is mutually parallel at this time,
Therefore, sorting trolley both will not left-right rotation, will not front and back rotation, so as to make sorting trolley keep horizontality, and
Its is opening up.When the advancing slip kinetoplast for sorting trolley enters the transfer trajectory of sorting track on right side, sort on the left of trolley
For slide mass also just into the transfer trajectory of the sorting track in left side, sorting trolley at this time still maintains opening up water afterwards
Level state and gradually decline.When advancing slip kinetoplast on the right side of sorting trolley enters the horizontal rail of sorting track lower layer on right side,
The rear slide mass in small left side is sorted also just into the horizontal rail of sorting track lower layer rearward, sorting trolley at this time is still
It keeps opening up horizontality and gradually moves backward.Therefore, sorting system of the invention is ensuring to sort trolley always
, it can be achieved that the three-dimensional of sorting track is arranged, to efficiently reduce accounting for for sorting system under opening up horizontality
Ground area advantageously reduces cost, improves efficiency.
It is understood that no matter sorting trolley Forward or rear shifting, it can start unloading mechanism and deliver package into side
In the sorting mouth of side.Therefore, we can minimize the arrangement spacing of the sorting mouth of sorting track both sides in the longitudinal direction, from
And be conducive to further shorten sorting track length, reduce the floor space of sorting system, be conducive to improve sorting speed and
Efficiency.
In order to simplify the structure of sorting trolley, annular closure can be respectively set in we on the sorting track of the left and right sides
Drive chain, forward and backward slide mass are connected with the drive chain of corresponding side respectively, sorting conveyer belt drive end setting with
The driven sprocket 25 engaged with drive chain is arranged in the driven end of sorting conveyer belt in the drive sprocket 24 of drive chain engagement,
And two drive sprockets are associated with synchronous drive mechanism.In this way, when two drive sprockets in synchronous drive mechanism driving left and right
When synchronous rotation, you can drive sorting trolley to be moved along sorting conveyer belt by the drive chain of left and right two.Correspondingly, divide
Unloading mechanism action can be driven by vehicle-mounted accumulator by package is made to enter sorting mouth corresponding with address by picking trolley, to have
Conducive to the power supply system of simplified sorting trolley, and improve the reliability of sorting trolley travelling.
As shown in Figure 9, Figure 10, synchronous drive mechanism of the invention includes the linkage of driving motor 4 and left and right directions arrangement
Drive sprocket 42 is arranged on the motor shaft of driving motor, synchronous chain is coaxially disposed on the left of the drive sprocket in left side for axis 41
Wheel 43, synchronous sprocket wheel is coaxially disposed on the right side of the drive sprocket on right side, and First Transition sprocket wheel is arranged in the right end of universal driving shaft
44, in the left end of universal driving shaft, the second transition sprocket wheel 45 and third transition sprocket wheel 46, drive sprocket and the second transition are abreast set
Sprocket wheel is connected by transmission chain, and third transition sprocket wheel is connected with the synchronous sprocket wheel in left side by transmission chain, First Transition chain
Wheel is then connected with the synchronous sprocket wheel on right side by transmission chain.
When driving motor works, i.e., the rotation of the second transition sprocket wheel is driven by drive sprocket, to pass through universal driving shaft band
It moves the first of both ends, third transition sprocket wheel to rotate, and then drives the drive sprocket of the left and right sides to rotate by synchronous sprocket wheel, with reality
Drive chain synchronous drive sorting trolley on now left and right sorting track smoothly moves.
In addition, as shown in Figure 11, Figure 12, also the tensioning motor 5 controlled by controller can be arranged in the front end of rack in we
And the preceding moving frame 50 that can be moved forward and backward, the driven sprocket of sorting conveyer belt driven end is arranged on preceding moving frame, preceding
Moving frame is associated with tensioning motor by transmission mechanism.When sorting system is run after a certain period of time, drive chain can be gradually
It extends and relaxes, at this point, we can start tensioning motor, tensioning motor drives preceding moving frame to Forward by transmission mechanism
It is dynamic, it is moved forward to drive the driven sprocket of left and right two to synchronize, makes the two drive chain synchronous tensions in left and right.Specifically, if
Set tensioning motor and preceding moving frame between transmission mechanism include be tensioned motor motor shaft be connected preceding worm screw 52,
The preceding swivel nut 54 that the preceding worm gear 53 engaged with preceding worm screw in rack front end is set, is arranged on preceding moving frame, the snail of preceding worm gear
The preceding leading screw 56 being threadedly coupled with preceding swivel nut is coaxially disposed on wheel shaft.When being tensioned motor rotation, you can worm screw turns before driving
It moves, to drive preceding worm gear rotation, preceding leading screw rotation at this time, and drive preceding moving frame smoothly to move by preceding swivel nut, with
Realize the synchronous tension of two drive chains in left and right.
In addition, we can also after the rear end of rack is arranged the rear worm wheel 59 of worm screw 58 and the engagement of rear worm screw, front and back can move
Dynamic rear moving frame 51, accordingly, it is desirable to drive sprocket and synchronous drive mechanism are arranged on rear moving frame, so as to
In its overall movement.One rear thread sleeve 55 is set on moving frame again afterwards, is arranged and rear thread sleeve screw thread on the worm gear shaft of rear worm wheel
The rear leading screw 57 of connection.Preferably, sprocket wheel can be respectively set in we on the worm shaft of rear worm screw and preceding worm screw, and at two
Transmission chain is set between sprocket wheel, to keep tensioning motor associated with rear worm screw.
When being tensioned electric motor starting, moving frame moves forward before on the one hand driving, and on the other hand passes through rear worm screw, rear snail
Leading screw rotates after wheel drives, so that moving frame moves backward after being driven by rear thread sleeve, to make forward and backward moving frame can court
The opposite identical distance of direction synchronizing moving, had not only realized the tensioning of drive chain, but also the center of sorting conveyer belt can be made to begin
It remains unchanged eventually, advantageously ensures that package is delivered the accuracy into sorting mouth by sorting trolley.
Further, as shown in figure 13, preceding worm gear of the invention include key connection central axle sleeve 521 on the worm gear shaft,
The external toothing 522 engaged with preceding worm screw, the disc 523 being integrally attached between central axle sleeve and external toothing, the one of disc
Side bonding resistance foil gauge 6, resistance strain gage is electrically connected with the controller.
When controller starts tensioning motor to be tensioned drive chain, the disc of preceding worm gear generates torque and deforms, this
When resistance strain gage just will produce an electric signal corresponding with torque.When the tensile force of drive chain reaches setting value
When, electric signal caused by resistance strain gage synchronously arrives at setting value, and controller can make tensioning motor be stopped at this time.Phase
Ying Di, when drive chain gradually relaxes and tensile force becomes small, the torque that the disc of preceding worm gear is subject to is gradually reduced, at this time resistance
The electric signal of foil gauge correspondingly reduces.When the electric signal of resistance strain gage drops to setting value, controller controls tensioning
Motor works, to realize the auto-tensioning of drive chain, to ensure that the tensile force of drive chain maintains suitable section.
To accurately control the tensile force of drive chain, we can also be keyed a strain axis on the worm gear shaft of preceding worm gear
Set 524, the strain axle sleeve recline central axle sleeve, and the fanning strip 525 radially extended is arranged in the outside for straining axle sleeve.In preceding worm gear
Storage tank 526 is arranged close to the side of strain axle sleeve in disc, and fanning strip is rotatably positioned in storage tank, to make fanning strip
Surface is flushed with the side of disc.Certainly, a stair-stepping bending can be arranged in fanning strip, in order to which it is located in storage tank.
One end of resistance strain gage is bonded in the surface of fanning strip, and the other end is then bonded in the side of the disc flushed with fanning strip.This
Sample, before worm gear shaft drives when worm gear rotation, strain axle sleeve, fanning strip and worm gear shaft rotate synchronously, and preceding worm gear is by negative
The effect of load, disc under the action of load torque can and fanning strip form a dislocation, resistance strain gage at this time by
One linear tensile stress, to make the torque suffered by preceding worm gear and can be formed between the electric signal of resistance strain gage simple
Linear relationship, and then be conducive to controller and drive chain tensile force accurately controlled.
In order to improve stability when sorting trolley movement, as shown in Fig. 6, Fig. 7, Fig. 8, we can be on the right side of sorting trolley
The setting of rear end and rear slide mass corresponding position after sliding pin 34, the front end on the left of sorting trolley and advancing slip kinetoplast corresponding position
Front slide pin 33 is set.Correspondingly, horizontal rib 26 is respectively set in the outer edge on the inside of two horizontal rails in left and right, wherein right side
The inside of sorting track front end the conversion rib 27 that is connected with the horizontal rib of the side is set, the conversion rib is in semicircle
Shape, and the shape of the conversion rib is corresponding with the transfer trajectory on front side of the sorting track in left side.Analogously, point in left side
The inside for picking track rear end is arranged the conversion rib that is connected with the horizontal rib of the side, the conversion rib semicircular in shape, and
The shape of the conversion rib is corresponding with the transfer trajectory on rear side of the sorting track on right side.In addition, the sorting track rear end on right side
The rear conversion rib 29 being connected with the horizontal rib of the side, and the sorting track of the shape and left side of conversion rib afterwards are set
The transfer trajectory of rear side is corresponding.The forward shift side that the sorting track front end setting in left side is connected with the horizontal rib of the side
28, and the shape on forward shift side is corresponding with the transfer trajectory on front side of the sorting track on right side.In this way, the sorting in left side
The oblong being made of the conversion rib of the forward of upper and lower two horizontal ribs, front end shift side, rear end is formed on the inside of track
Position rib, formed on the inside of the sorting track on right side by upper and lower two horizontal ribs, the conversion rib of front end, rear turn of rear end
The positioning rib of the oblong for side composition of shifting gears.In addition, we need to also position the horizontal rib and conversion rib of rib at two
Intersection setting may be allowed the opening that forward and backward slide mass is crossed, and in opening rotatably arranged with the switching door for blocking opening
7.Certainly, we also need the lockable mechanism that setting can be such that switching door switches between open state in off position.
It should be noted that the axis of forward and backward sliding pin is the level of left and right directions as the axis of forward and backward slide mass
Arrangement, and the length of forward and backward sliding pin is less than the length of forward and backward slide mass, and corresponding one is reclined to make to slide back and forth pin
The inside of side positioning rib, and forward and backward slide mass is then crossed positioning rib and is connected in drive chain, to make sorting trolley
Form reliable four point positioning.
When drive chain drives sorting trolley to be moved forward in the horizontal rail for sorting track upper layer, forward and backward sliding
The corresponding horizontal rib that reclines respectively is sold, sorting trolley at this time forms four point positioning, to can ensure that the steady of its movement.When
When advancing slip kinetoplast on the right side of sorting trolley is moved to the horizontal rib on right side with conversion rib intersection, advancing slip kinetoplast first triggers lock
Locking mechanism and push switching door open, to continue to move forward on sorting track, until advancing slip kinetoplast enters transfer trajectory, then slide afterwards
Dynamic pin is taken advantage of a situation by switching door into conversion rib by horizontal rib.Correspondingly, sort front slide pin on the left of trolley first by
Horizontal rib is smoothly transitioned into forward shift side, and then rear slide mass is moved forward in horizontal rail up to entering transfer trajectory,
And then so that sorting trolley is remained stable and move horizontally state.
Start to enter the horizontal rail of lower layer from the transfer trajectory of front end and when moving backward, sort trolley when sorting trolley
The rear sliding pin on right side is first moved to the horizontal rib of downside by conversion rib by switching door, and then advancing slip kinetoplast triggers locking
Mechanism and push switching door open, to being entered the horizontal rail of lower layer by transfer trajectory and be moved back.Correspondingly, sorting trolley is left
The horizontal rail that the rear slide mass of side is then first smoothly entered lower layer by transfer trajectory sees that then front slide pin is shifted gears side by forward
It is smoothly transitioned on the horizontal rib of lower layer.
The conversion rib for the horizontal rib and rear side that after slide mass on the left of sorting trolley is moved rearwardly into lower layer has a common boundary
When place, rear slide mass triggers lockable mechanism and pushes switching door open, to continue to be moved after on sorting track, until rear slide mass into
Enter transfer trajectory.At the same time, front slide pin is then taken advantage of a situation by switching door into conversion rib by the horizontal rib of lower layer.Relatively
Ying Di sorts the advancing slip kinetoplast on the right side of trolley and is then moved after sorting on track until entering transfer trajectory, rear sliding pin is then under
The horizontal rib of layer converts rib after being smoothly transitioned into, and then so that sorting trolley is remained stable and move horizontally state.
When sorting trolley starts to reenter horizontal rail and the forward movement on upper layer from the transfer trajectory of rear end, sorting
Advancing slip kinetoplast on the right side of trolley is first smoothly entered horizontal rail and the forward movement on upper layer by transfer trajectory, then rear sliding pin
The horizontal rib on upper layer is smoothly transitioned by rear conversion rib.Correspondingly, the front slide pin on the left of trolley is sorted first by turning
Shift side is smoothly transitioned on the horizontal rib on upper layer, and then rear slide mass triggers lockable mechanism and pushes switching door open, until
Slide mass is entered the horizontal rail on upper layer by transfer trajectory afterwards.
And so on, sorting trolley can on sorting track smoothly loopy moving.
As shown in Figure 14, Figure 15, lockable mechanism of the invention includes being arranged in horizontal rail to horizontal shifting
Pivot pin 8, the lock pin 9 being arranged with being vertically movable on horizontal rib.One pivot pin of setting is needed to perforate 91 on lock pin, and
A resetting spring 92 is arranged on lock pin, resetting spring makes lock pin be located in lock position.One end of pivot pin reclines lock pin at this time
Side, lock pin play the role of pivot pin the locking of limitation axial movement.Rotatable switching door is set in rotation axis including one
Above the tooth with external tooth covers 71, and the rack 81 being meshed with tooth set is arranged in the other end far from lock pin on pivot pin, in switching door
One reduction torsion spring is set in rotation axis, and reduction torsion spring makes the automatic positioning of switching door in off position.
For current slide mass when moving forward to horizontal rib in horizontal rail with conversion rib intersection, advancing slip kinetoplast is first
Push lock pin, lock pin vertical shift to the pivot pin perforation unlocked position opposite with the pivot pin for the lock pin that reclines.Then advancing slip kinetoplast pushes away
Switching door is squeezed, to be inserted into the pivot pin perforation of lock pin by tooth set, rack drives pivot pin movement, switching door is converted to unlatching
State, advancing slip kinetoplast can easily cross the opening of horizontal rib and conversion rib intersection and enter transfer trajectory.Then multiple
Position torsional spring driving switching door automatically resets to closed state, and exits lock pin by tooth set, the movement of rack drives pivot pin direction
Pivot pin perforation, at this time resetting spring driving lock pin vertical shift reset lock position, switching door be locked at closing shape again
State.
It is understood that the process that rear slide mass opens switching door is similar with foregoing description, it is not repeated to retouch herein
It states.In addition, the position of lock pin should be close proximity to drive chain side, and the length of forward and backward sliding pin is ensureing the positioning that can recline
Should be short as possible on the basis of rib, in order to avoid lock pin is touched when moving.
