Abstract
The invention relates to a caching device for letter sorting, which is characterized by comprising a letter supply belt for supplying a letter caching area; a movable caching boat is arranged on the letter supply belt, and comprises a first letter clamping belt pulley set, a second letter clamping belt pulley set and a pressure sensing device; the first and second letter clamping belt pulley sets form a letter transfer passage; and the tail end of the letter transfer passage is connected with the upper part of the letter supply belt. A letter enters the caching area in a position above the letter supply belt as soon as leaving the letter transfer passage; during work, the movable caching boat conducts reciprocating pushing movement in the letter supply direction, so as to ensure that letters entering the caching area are kept parallel to a separation belt pulley, and a certain clearance, namely tightness, is kept between letters in the caching area through the pressure sensing device; the movable caching boat moves under the action of a servomotor; the operating speed of the separation belt pulley is larger than or equals to the transferring speed of the letter transfer passage; and the pushing position of the movable caching boat is defined according to the pressure of the pressure sensing device.
Description
Technical field
The present invention relates to a kind of buffer storage for letter sorting, belong to logistics sorting technical field.
Background technology
The process of letter sorting can simply be expressed as: two belts clamp letter and move forward by envelope, code-reading apparatus is set in course of conveying, the information such as the parcel received of letter or outbox address are read, according to different reading informations, letter is delivered to corresponding diverse location with belt by shunting, for improving sorting speed, Belt Conveying speed also needs to improve, Belt Conveying speed is generally 4m/s at present, and need analyzing and processing after needing after the code-reading apparatus reading code information that reads identified, present analysis is processed the needed time and is generally 9s, and therefore, letter needs to continue the rice with belt walking 4*9=36 at least after by reading code, just can be sorted out, because track is very long, to take up an area too greatly, prior art generally adopts Postponement module to solve this problem, shown in Figure 1 is existing a kind of Postponement module, allow the belt that drives the letter walking carry out repeatedly bending a module, thereby reduce its entire length, reduce floor space.It is larger that but this Postponement module still takes up an area, and, along with requiring degree of refinement, present sorting improves, the increasing of reading code information content, the time of after the reading code information analysis being processed also prolongs to some extent, and what have extends to 20s, Postponement module needs more XXL, production cost is also higher, and equipment too greatly also can't enter the postal terminals such as delivery office, needs company and the department of high speed processing large information capacity on also can't entering society.
Summary of the invention
The technical issues that need to address of the present invention are: along with the information content increasing of letter sorting reading code, the analyzing and processing time lengthening, the volume of letter Postponement module is increasing, production cost is too high, simultaneously volume is excessive is difficult to enter relevant postal terminal, needs company and the department of high speed processing large information capacity on also can't entering society.
The present invention adopts following technical scheme:
A kind of buffer storage for letter sorting, described buffer storage comprises provides the letter that supplies of letter buffer zone to be with 1, the described letter that supplies is with 1 to be provided with the mobile caching boat, described mobile caching boat comprises first, second folder letter belt pulley set of vertical setting, described corresponding applying of belt that first, second presss from both sides the letter belt pulley set forms the letter transfer passage, and the drive letter moves along the belt rotation direction; The end of described letter transfer passage is connected with 1 top for letter with described, and described mobile caching boat can be with 1 direction reciprocating and with to separate belt pulley 2 corresponding along described confession letter; Described letter breaks away to be buffered in behind the described letter transfer passage describedly is with 1 top for letter, and simultaneously between separation belt pulley 2 and mobile caching boat, the position that described mobile caching boat is corresponding with separating belt pulley 2 is provided with pressure sensor device 4b; Described mobile caching boat is driven by servomotor 3, the running speed of described separation belt pulley 2 is more than or equal to the transporting velocity of letter transfer passage, and corresponding with the little progress speed of mobile caching boat, the propelling position of described mobile caching boat is determined by the pressure setting of described pressure sensor 4b; Described buffer storage is arranged on the support platform.
Further, described mobile caching boat comprises drive transfer combination 4, described drive transfer combination 4 is slidingly matched with the slide combination, described servomotor 3 drives described drive transfer combination 4 and slides in described slide combination, described drive transfer combination is set in the first folder letter belt pulley set, the part belt pulley of described the first folder letter belt pulley set is fixed in the described drive transfer combination 4, carry combination 4 to move and mobile with described transmission, comprise a compensation belt pulley 4a in the described part belt pulley, described compensation belt pulley 4a compensates the Belt Length of described the first folder letter belt pulley set, so that described drive transfer is combined in when sliding in the described slide combination, the all the time tensioning of belt of described the first folder letter belt pulley set, and keep Belt Length not change.
Further, the described letter that supplies is with 1 to be provided with gas hole, and described gas hole is blown to described letter, makes it loose.
A kind of method of work of buffer storage is characterized in that, may further comprise the steps:
1) driven by servomotor drive transfer combination 4 is moved to separating belt pulley, and with separate the corresponding applying of belt pulley;
2) letter enters the letter transfer passage by envelope, move with the letter transfer passage, drive transfer combination 4 is driven to away from the direction of separating belt pulley adjusting microinching progressively by servomotor 3, and letter enters described buffer zone successively, until drive transfer combination 4 moves to desired location;
3) separate belt pulley 2 and start, the letter in the buffer zone separates by envelope successively by separating belt pulley 2 drive letters, and the letter of follow-up letter transfer passage enters the buffer zone successively simultaneously;
When 4) treating that the letter transfer passage provides without new letter, drive transfer combination 4 reduces synchronously forward adjusting microinching with the letter of buffer zone, until the buffer zone is without letter;
5) drive transfer combination 4 resets, and moves to initial, set position along the slide combination.
Characteristics of the present invention are: by using the form of mobile caching boat, for letter provides a buffer zone, the time of setting buffer memory is slightly greater than time of reading code information analysis and processing, so that letter is before further being sorted, code-reading apparatus has the sufficient time to carry out analysis and the processing of information, simultaneously, equipment continued running and uninterruptedly, does not affect starting of sorting conveying equipment when letter was buffered.
Beneficial effect of the present invention is:
1) improves the large information capacity analyzing and processing time.
2) the existing Postponement module of volume ratio reduces greatly, lowers the module production cost more than 80%.
3) make product can come into eventually postal as end delivery office after the device miniaturization, entering society simultaneously needs the company of high speed processing large information capacity and department, and widely promotion prospect and commercial value are arranged.
