The mid-track switch reversing arrangement of electric drive
The utility model relates to a kind of logistics delivery track or guide rail, and the particularly track switch reversing arrangement between two tracks specifically, is the mid-track switch reversing arrangement of a kind of electric drive.
In prior art, utilize roller to walk in trapped orbit or guide rail, can make roller connect object or workpiece by preset path displacement, in transport and conveying technology, generally use this technology, but in the time that two tracks occur to intersect in same plane, need to a direction reverser be set at cross section, at the track of a corresponding appointment of the time of an appointment, make the track of specifying form passage completely, part Channel-shifted member of the prior art or allied equipment are without realizing conversion by external force, its design of part relative complex and difficulty of processing are large, the stability of its work and reliability are also subject to the impact of factors.
Need just can not complete auto reversive Channel-shifted member by external force at present and have a kind of form, structure as shown in Figure 1, track 1 and track 3 are at same straight line, walking roller is along track 1 to track 3 direction walkings, first roller contact is to plate one B1, make plate one B1 around axle left-hand revolution, plate one B1 and plate two B2 link together by axle two Z2, plate one B1 drives plate two B2 to clockwise rotate around axle three Z3 when rotation, thereby plate two B2 have connected track 1 and track 3, make it form path, walking roller just can be along track 1, by plate two B2, arrive track 3, complete whole walking process, dotted line represents the action of other direction, move identical, just opposite direction, walking path becomes the path of track 2 and track 4.
Though this device is without direction that just can auto-changing passage by external force, its part that still comes with some shortcomings in actual use:
One, when walking roller contacts with plate one B1, because the running velocity of walking roller is larger, cause in the time that moment contacts, producing greater impact power between the two, the long-time service life that uses serious reduction part
Two, because of walking roller contact with one B1 moment of plate produce impulsive force very large, therefore moment produce impact noise also larger.Affect Whole Equipment noise index.
Three, respectively there is respectively a cushion blocking J plate two B2 both sides as can be seen from Figure, initial object is to clash into the noise producing when reducing plate two B2 and to turn to end position, though so design, noise reduces really to some extent, but cushion blocking J is elastic material, in two B2 contact cushion blocking moments of plate, plate two B2 can be subject to the antagonistic force of cushion blocking and eject certain distance, thereby cause plate two B2 and walking roller to have the phenomenon of touching, have potential safety hazard.
Four, plate one B1, plate two B2 and cushion blocking J are independent parts, when installation, locate separately, and this just causes existing accumulated error in installation process, finally cause cannot meeting set-up function after equipment installation.
Summary of the invention
The utility model technical issues that need to address are: existing mid-track switch reversing arrangement, though without direction that just can auto-changing passage by external force, there are four deficiencies as described in the background art, the utility model is intended to solve these weak points.
The utility model is taked following technical scheme:
The mid-track switch reversing arrangement of a kind of electric drive, comprises adapter plate 4, S. A. 1, reversing plate 2, walking roller 3, the walking passage that a pair of mutual intersection is symmetrical: de passage and bf passage; Described reversing plate 2 is equicrural triangle, and equicrural triangle base place is hinged by S. A. 1 and adapter plate 4; Described walking roller 3 is walked in a pair of walking passage that intersection is symmetrical mutually; Described reversing plate 2 is driven and is swung by o, the be alternately communicated with/sealing of described a pair of walking passage.
The feature of the technical program is: adopt the power of o as track switch commutation, two sides of the reversing plate of equicrural triangle have played the directional tagging to walking roller, by swinging of reversing plate, alternately realize the connection/sealing of two walking passages.
Further, when described reversing plate 2 swings left, equicrural triangle right edge and described de channel parallel.
Further, when described reversing plate 2 swings to the right, the limit, left side of equicrural triangle and described bf channel parallel.
Further, described de passage and bf passage are equipped with guide plate separately.
Further, the rectangular structure of described adapter plate 4.
The beneficial effects of the utility model are:
1) overall structure form, has reduced the quantity of part.Structure of the present invention is an independent assembly, after assembly installation independently, only module whole need be arranged on certain stay bearing plate, so just greatly reduces accumulation installation error, reduction installation difficulty.
2) in actual applications, current mid-track switch reversing arrangement there will be the antagonistic force or other various reasons that produce due to cushion blocking moment impact, cause reversing plate to have the phenomenon that rests on midway location, thereby cause commutation action to have failed hidden danger, in the present invention, owing to relying on electric drive to retrain the position of deflecting plate, can have actv. ensure walking roller safety, smoothly by the position of deflecting plate.
3) use electric drive, sensor and control circuit, working stability, reliable.
4) sorting arrangement integral structure is light, and alerting ability is good, and cost performance is high, greatly reduces client's actual use cost and maintenance cost.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
The present invention is mainly used in logistics automatic sorting apparatus, particularly, in slide block type sorter, moves to the commutation function of specifying track switch for the slide block of realizing on sorter
Detailed description of the invention is as follows:
Referring to Fig. 2, the mid-track switch reversing arrangement of electric drive, always has three vital parts compositions, comprising: adapter plate 4, reversing plate 2 and S. A. 1.
Further illustrate the course of action of this device as an example of Fig. 2 example, first walking roller 3 enters position a in this device by outside other tracks, walks to position b along the indicated direction of walking arrow.At walking roller from before outside other track in-positions a, system just judges that reversing plate should forward b position to, make position a, b, f form path, walking roller just can be from position a in-position f after the b of position, complete commutation action, molar behavior is steady, nature, reliable, and vibrations and noise are all lower.
Shown in dotted line, operating principle is identical, and just opposite direction, realizes two-way commutation function.
Adopt finite element analysis, material to vital part and structure are carried out design of Simulation and optimization process, part service life and serviceability are improved, impulsive force and noise that slide block on slide block type sorter is produced in the time of automatic reverse reduce greatly, the stability and the reliability that provide equipment to use.
On slide block type sorter, adopt the mid-switch reversing mechanism of electric drive of the present invention to substitute current mid-switch reversing mechanism, can realize the high speed commutation function of slide block at mid-switch location, make percentage error and the fault rate of track switch commutation greatly reduce simultaneously, no matter theoretically or in reality, all can there is not the phenomenon of slide block and reversing plate collision, make running velocity, sorting efficiency, life cycle, the use cost of the sorting mechanical equipment that uses the technology of the present invention all have significantly and improve than current similar sorting product.
