A kind of transmission turning device that is used for mail irradiation system
Technical field
The present invention relates to utilize accelerator that mail is carried out the system of irradiation sterilization, especially for the transmission turning device of mail irradiation system.
Background technology
Since outburst anthrax at the beginning of 10 months calendar year 2001s, case is infected in existing many of the U.S. whole nation, wherein existing many people death.This class the infected, all being identified as is to have contacted the mail that has anthrax bacillus or parcel and infected.Anthrax is a kind of killed pathogenic bacteria that is difficult to, so be easy to be propagated with modes such as mail, parcel and other express mails.And utilize the electron beam irradiation of certain energy can kill anthrax.At present, bring bigger harm for fear of anthrax to the mankind, each state all kills anthrax stepping up to develop relevant various device.In the prior art, but Beijing Atom HighTech Co., Ltd. has developed the system at the self-shileding of mail sterilization.So-called self-shileding is exactly that system finishes protective shielding by the preventer of self, and does not need the help of extraneous medium.This system is positioned in the common house, a building, and its machinery is made up of preventer, transmitting device two parts.During irradiation sterilization, the staff is placed on the transmitting device porch with mail, and transmitting device is sent mail into irradiation zone, by accelerator mail is carried out radiation sterilizing, after irradiation is finished, by transmitting device mail is sent again, finishes sterilization process.The shortcoming that adopts this technical scheme is because transmitting device is an one-way transmission, is subjected to the restriction of accelerator energy, so the irradiation depth that can reach is very limited.
Summary of the invention
In order to overcome the shortcoming that exists in the above-mentioned prior art, the purpose of this invention is to provide a kind of transmission turning device that is used for mail irradiation system, it can transmitted in both directions and makes mail thing turn-over, to increase its irradiation sterilization thickness.
In order to achieve the above object, technical scheme of the present invention realizes with following mode: a kind of transmission turning device that is used for mail irradiation system, it comprises the mail turnover box, horizontal transport mechanism and vertical slide mechanism, its construction features is, described mail turnover box places on the described horizontal transport mechanism can carry out horizontal reciprocating movement, described vertical slide mechanism places horizontal transport mechanism both sides, vertical slide mechanism can be mentioned mail turnover box at the volley, gravity by mail turnover box self will become vertical state by level, be advanced by horizontal transport mechanism to make the mail turnover box realize upset in horizontal transport mechanism again.
According to technique scheme, described mail turnover box is closed box body, and box body outer wall both sides are provided with the relatively protruding axle on one side.Described horizontal transport mechanism is made up of framework, motor, sprocket wheel, chain and tray carriage, motor is by the variator drive sprocket, mesh chain on the sprocket wheel, the two ends of chain are connected with the front and back end of the tray carriage that can carry the mail turnover box respectively, and the bottom of tray carriage is provided with the wheel of frame in the framework upper surface.Described vertical slide mechanism is made up of two framings, sprocket wheel, chain, driving slide block and a motor.Each framework vertically places the both sides of horizontal transport institutional framework respectively.The upper and lower side of each framework is installed sprocket wheel, meshes chain on the sprocket wheel, and the two ends of chain are connected with two front ends up and down that drive slide block respectively.Each drives slide block and is inlaid in the slideway set in the framework, and each medial surface that drives slide block is provided with the groove that matches with the set protruding axle of being partial on one side in described mail turnover box both sides.
The present invention is that mail is packaged in the box body of sealing when irradiation owing to adopted above-mentioned version, in the irradiation process mail turnover box is carried out turn-over.Compare with prior art, the present invention is under situation about using with the accelerator irradiation of homenergic, and it is above that the depth of radiation sterilizing is doubled, and enlarged the scope of application of sterilizing article.
Description of drawings
Fig. 1 is a population structure sketch map of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left side view of Fig. 1;
The present invention is described further below in conjunction with the drawings and specific embodiments.
The specific embodiment
Referring to Fig. 1~Fig. 3, a kind of transmission turning device that is used for mail irradiation system comprises mail turnover box 3, horizontal transport mechanism 1 and vertical slide mechanism 2.Described mail turnover box 3 places on the described horizontal transport mechanism 1, can carry out horizontal reciprocating movement.Described vertical slide mechanism 2 places horizontal transport mechanism 1 both sides.Vertical slide mechanism 2 can be mentioned mail turnover box 3 at the volley, will become vertical state by level by the gravity of mail turnover box 3 self, is advanced by horizontal transport mechanism 1 to make mail turnover box 3 realize overturning in horizontal transport mechanism 1 again.
The concrete embodiment of the present invention adopts: described mail turnover box 3 is closed box body, and box body outer wall both sides are provided with the relatively protruding axle 31 on one side.Described horizontal transport mechanism 1 is made up of framework 11, motor 12, sprocket wheel 13, chain 14 and tray carriage 15.Motor 12 meshes chain 14 by variator drive sprocket 13 on the sprocket wheel 13, the two ends of chain 14 are connected with the front and back end of the tray carriage 15 that can carry mail turnover box 3 respectively.The bottom of tray carriage 15 is provided with the wheel 16 of frame in framework 11 upper surfaces.Described vertical slide mechanism 2 is made up of two framings 21, sprocket wheel 22, chain 23, driving slide block 24 and a motor 25.Each framework 21 vertically places the both sides of horizontal transport mechanism 1 framework 11 respectively.The upper and lower side of each framework 21 is installed sprocket wheel 22, engagement chain 23 on the sprocket wheel 22, and the two ends of chain 23 are connected with the two ends up and down that drive slide block 24 respectively.Each drives slide block 24 and is inlaid in the slideway set in the framework 21, and each medial surface that drives slide block 24 is provided with protruding axle 31 grooves that match 26 relatively set with described mail turnover box 3 both sides on one side.When the protruding axle 31 of embracing mail turnover box 3 when groove 26 moves up, because the protruding axle 31 in the both sides of mail turnover box 3 relatively on one side, gravitate mail turnover box 3 becomes vertical state by level, and tray carriage 15 propellings by horizontal transport mechanism 1 make mail turnover box 3 realize upset on tray carriage 15 again.
The present invention in use can replace transmitting device of the prior art, is placed on the radiation source place, under computer program control, realize control operation automatically, make mail turnover box 3 through an irradiation, then turn-over is sent by horizontal transport mechanism 1 through behind another irradiation again.The present invention is applicable in various dissimilar mail irradiation systems and other plant equipment.
What be worth to propose is, in above-mentioned technical scheme, the kind of drive of described sprocket engagement chain also can otherwise be equal to replacement, passes through the kinds of drive such as belt, screw mandrel of usefulness as employing.The technical scheme that suchlike transmission and transmission form form all should belong to protection scope of the present invention.
