A kind of belt conveyer
Technical field
The present invention relates to a kind of belt conveyer, specifically, be that a kind of can realization keeps attitude to have the belt conveyer of positioning function when being transferred object commutation, belong to Belt Conveying technical field.
Background technology
In present logistics conveyer system, the Main Function of belt feeder and operational mode are inputted along belt direction of travel by article, through the equidirectional conveying of belt feeder, exports from the other end by belt direction of travel.For by the article of belt transport, its position on belt by belt bonding cut somebody's hair and can realize along belt direction of travel relatively fixing.Substantially be position with the baffle plate of belt feeder side for the location perpendicular to belt direction of travel, or make that belt feeder is enough wide does not position control.
Article are entered by with belt transport direction is angled, and requires to remain that this angle state exports along the translation of Belt Conveying direction, this being used in the application of belt feeder there is no.Such as, but some specific object, the mail of flats, the article such as letters, it proposes such requirement in the process of belt transport, and existing belt conveyer is difficult to strictly meet above-mentioned requirement.
In order to make belt conveyer realize above-mentioned operational mode, Curve guide impeller must be carried out to belt composition.
Summary of the invention
The technical issues that need to address of the present invention are: article be made to enter at an angle by with belt transport direction, and require to remain that this angle state exports along the translation of Belt Conveying direction, and existing belt conveyer is difficult to strictly meet above-mentioned requirement.In order to make belt conveyer realize above-mentioned operational mode, Curve guide impeller must be carried out to belt composition.
The present invention takes following technical scheme:
A kind of belt conveyer, comprises supporting seat 1, transferring roller 2, belt 4, described transferring roller 2 drives belt 4 to rotate, and it is characterized in that: described belt 4 is fixedly set up location guiding element 403, and the storage area that described location guiding element 403 surrounds is the bottom attitude of object to be transported when entering; The knock hole 401 corresponding with described location guiding element 403 offered by described belt 4, described belt conveyer is also provided with the detection and location device corresponding with knock hole 401, described belt 4 starts prelocalization and is waiting for the position that object to be transported enters; Its mode of operation is: object to be transported translation enters described storage area above described belt 4, comes to a complete stop; Described belt 4 starts, and object to be transported enters next station; Belt 4 again waits for entering of next object to be transported with knock hole 401 for benchmark is parked on fixed position after completing an action cycle.
Described location guiding element 403 is uncovered on the direction of object to be transported approaching side.
Described object to be transported is the letter of flats.
Described location guiding element comprises the barrier rib of many strips, and described barrier rib is fixed on described belt 4, and the height of barrier rib is higher than the thickness of described letter.
The inner side of described belt 4 can be provided with gib block 402 along its rotation direction.
Described belt 4 is provided with the knock hole 401 of several equidistant setting, and the array corresponding with described knock hole 401 locates guiding element 403.
Feature of the present invention is: by carrying out the improvement in structure and control method to belt conveyer self, achieving object to be transported keeps original attitude to enter above the belt of this belt conveyer from previous feedway, is convenient to follow-up sorting conveying.This belt conveyer is particularly useful for carrying out conveying sorting to the letter of flats, and because letter deadweight is lower, easily change attitude after entering belt conveyer, its neat rate lowly brings very large puzzlement to subsequent delivery sorting.The present invention well solves this technical matters, achieves the accurate control of belt and the precise delivery to article.
Although original intention of the present invention is conceived to the problem of the conveying location solving flats letters, the implementation of principle of the present invention and technical scheme is not limited to flats letters, is equally applicable to the logistics transportation of usual articles, sorting.
Beneficial effect of the present invention is:
1) technical barrier keeping original attitude is difficult to after the article solved and belt transport direction enter at an angle.
2) structure is simple, realizes easily.
3) obviously equipment cost is not increased.
4) locating effect is obvious, has the prospect extensively promoted.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described.
See Fig. 1, a kind of belt conveyer for conveying flat shape letters, comprises supporting seat 1, transferring roller 2, belt 4, and described transferring roller 2 drives belt 4 to rotate.
See Fig. 1,2, belt 4 is fixedly set up location guiding element 403, location guiding element 403 is made up of many barrier ribs, and its height need a little more than the thickness of flats letters.The shape of the storage area that many barrier ribs surround is the bottom attitude of letter to be conveyed when entering, and wherein, opens wide towards the direction that letters to be conveyed enter.The knock hole 401 corresponding with locating guiding element 403 is offered in position belt 4 being positioned at location guiding element 403 other, belt conveyer is also provided with the detection and location device corresponding with knock hole 401, confirm whether the position of knock hole puts in place for scanning, before belt 4 starts, the location guiding element 403 on its top is in the position of waiting for that letters to be conveyed enter;
Its mode of operation comprises the following steps: letters translation to be conveyed enters described storage area above belt 4, comes to a complete stop; Belt 4 starts, and letters to be conveyed enter next station; Belt 4 again waits for entering of next letters to be conveyed with knock hole 401 for benchmark is parked on fixed position after completing an action cycle.
The inner side of belt 4 is provided with gib block 402 along its rotation direction, and gib block 402 rotates with belt, belt 4 is played to the effect of guiding, departs from original position when preventing belt from rotating.
Belt 4 is provided with three knock holees 401 equidistantly arranged, and the location guiding element 403 that three groups corresponding with described knock hole 401, and belt often rotates 1/3rd length, completes the conveying of letters.
The present embodiment by reasonably conversion, can also change the shape of location guiding element 403, highly, material, and change its shape surrounded, can also realize the conveying to other article, the scope that therefore belt conveyer of the present invention is contained is not limited to the conveying to flat letter.
