Abstract

The utility model relates to a signature device for indicating event time in mailing letters or other similar situations. On the basis of the existing letter stamping machine, a letter separating part is changed into a turning separating structure which comprises a turning pre-separating feeding device and a turning separating unit, feeds along a tangential line and travels along a curved line. The signature device has the advantages of steady and reliable letter separation without the influence of the self factors of the letters, 100% separation, small size, simplified structure, reduced cost and reduced operating cost.

Description

Steering separated stamper

The utility model relates to send by post a kind of seal device of letter indication event time or other similar applications.

All must be on mail after which kind of letter service by post delivery office cancelling land date stamp.This work is finished by manually-operated usually, requires the necessary high concentration of staff's notice, careful conscientious, to prevent that the date stamp cancelling is unclear or the Cancellation Missed accident to occur.So this labor intensity is big and work efficiency is low, has to increase the staff sometimes and accelerate cancelling.A kind of letter dater-stamp application machine has been finished in relevant department's design, it is by transport portion, the mail separating part, roll the stamp part, photoelectric detection part, hop and electronic circuit control etc. are partly formed, transport portion is delivered to the workspace to mail in a pile, the separating part of workspace is the key device of stamping machine, it adopts by air pump, pipeline, suction is chewed and is stopped belt, counter-rotating stops that wheel waits the straightaway aspirated-air type structure that constitutes, to wait that the mail that stabs was adsorbed onto the surface of transport tape, because mail is subjected to stopping that belt and counter-rotating stop the inhibition of wheel in the absorption transmission.And the separation one by one between the realization mail---only allow an envelope letter to pass through at last.Finish this work through actions such as rolling stamp, Photoelectric Detection counting, transmission again.This device performance is comprehensive, automaticity is high, obviously improves working condition, improves work efficiency.But its weak point is: the aspirated-air type structure of separating part, the suction size of aspiration is set up by a certain standard sample letter, when the papery of mail, thickness, size, the equal standard of weight, the leakage branch rate that aspiration separates can be controlled in the critical field of 1-6%; And always there is certain difference in these factors of mail in the real work, can not be balanced consistent, to thin, light just might adsorb two envelopes or more than, cause Cancellation Missed to land date stamp usually between 10-20%, even reach more than 20%, the phenomenon of doing over again is serious, i.e. working stability, poor reliability.Next is exist to adopt air pump equal power device and straightaway transmission structure, makes the volume of device big, complex structure, and benzene is heavy, and operating noise is big, all more high drawback of cost and usage charges.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of working stability, reliable is provided, and volume is little, simply constructed stamping machine product.

Can take following technical scheme to realize purpose, on the basis of existing letter dater-stamp application machine, the mail separating part be changed the tangential admission, the curve that are made of revolution pre-separation feed arrangement and the revolution break-in separator break-in isolating construction of advancing.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of steering separated stamping machine separating part.

The steering separated stamping machine also comprises transport portion, separating part, rolls parts such as stabbing part, photoelectric detection part, hop and electronic circuit control, and the function of each several part is same as the prior art.Advance the break-in isolating construction except that separating part adopts tangential feed pre-separation, curve, all the other each funtion parts can keep according to prior art fully, also can take the circumstances into consideration to remove certain part or use other structure instead.

The effect of the revolution pre-separation feed arrangement of separating part is the mail in a pile that transport portion is sent here to be flowed to revolution break-in separator with the least possible quantity from the bottom up successively proceed to separate, guarantee the reliability of separation by twice separation, especially turn round the break-in separator, even be that feed arrangement is once sent two, three envelope mails to, in long curve distance, along with continuous revolution break-in, under the effect of different directions power, make between letter and the letter and continue to increase dislocation, particularly by fully being separated behind the summit.

Can adopt separating part structure as shown in drawings, also can adopt other combination form to realize that the revolution break-in separates.In the accompanying drawing, revolution pre-separation feed arrangement mainly is made of revolution friction pulley (1), baffle plate (2) and metal runners (3); Revolution break-in separator mainly separates wheel (4) by revolution, wrap in separate the outer semicircle shape band (6) that is subjected to extension spring (5) control of wheel and metal runners, directive wheel (7) constitutes; Metal runners (3) be installed in respectively tangentially that the revolution friction pulley separates with revolution between the wheel and gyroscope wheel and directive wheel between.Mail enters revolution break-in separator through revolution pre-separation feed arrangement and obtains single mail at last, single mail separates under the effect of inertia of wheel in revolution, send, be subjected to the effect of directive wheel along the metal runners tangential direction and quicken to travel forward, behind Photoelectric Detection counting, rolling stamp, borrow the mail deadweight to fall then, finish cancelling and land date stamp.Extension spring (5) one ends are connected with band (6), and the other end and frame are fixed; Semicircle shape band (6) can adopt the manufacturing of rubber, plastics or rubber and plastic and so on material.

More effectively form the interrupted mail that separates for making revolution separate wheel (4), the periphery that separates wheel (4) in revolution is evenly equipped with 8 protrusion crossbeams (8) vertically, guarantee that the mail separating stable is reliable, reduce of the influence of factors such as mail papery, thickness, size, weight separating.

Revolution separates wheel (4) and wraps in that to separate between the outer semicircle shape band (6) that is subjected to extension spring (5) control of wheel with slight contact be good, and promptly the pulling force of spring can not be excessive or too small, otherwise influence service life or separating effect.

The relative prior art of the utility model has following advantage:

1, the mail separating stable is reliable, and is complete at peak position one front cover envelope mail Separated coming is not subjected to the impact of mail oneself factor, and effect is fairly obvious, can reach 100% and separate, avoids fully the Cancellation Missed phenomenon;

2, whole stamping machine volume reduces greatly, and the structure of separating part is obviously simplified, and noise is little during work, and cost and the usage charges of whole product all descend.

Claims

1, a kind of steering separated stamping machine, it by transport portion, separating part, roll and stab part, photoelectric detection part, hop and electronic circuit control part branch are formed, and it is characterized in that: its separating part is to be made of revolution pre-separation feed arrangement and revolution break-in separator.

2, steering separated stamping machine as claimed in claim 1 is characterized in that: revolution pre-separation feed arrangement mainly is made of revolution friction pulley (1), baffle plate (2) and metal runners (3); Revolution break-in separator mainly separates wheel (4) by revolution, wraps in and separates outside the wheel, constituted by the semicircle shape band (6) of extension spring (5) control and metal runners, directive wheel (7); Metal runners (3) tangentially is installed in friction pulley respectively and separates between the wheel and separate between wheel and the directive wheel.
