Flat articles transported along feed belts are guided to enter'into a space between a pair of endless belts moving in the reverse direction to the flat-article transport. Responsive to the detection of the passage of the trailing edge of the flat article in the flat-article transport, thespace between the pair of endless belts is narrowed by pressing one of the endless belts sideways with respect to the motion of the belt by means of a movable roller.
3 Claims, 4 Drawing Figures TRANSPORT-DIRECTION REVERSING APPARATUS FOR AN AUTOMATIC MAIL HANDLING, SYSTEM AND THE LIKE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a transport-direction reversing apparatus for an automatic mail handling system and the like.
2. Description of the Prior Art In a conventional mail handling system, such flatarticles as cards, envelopes and postcards must be ocasionally reversed in their transport-direction. For this purpose, various kinds of transport-direction reversing apparatuses have been proposed. One of those conventional apparatuses is described in the United States Patent No.3,339,705. However, in those conventional apparatuses, it is difficult to secure flawless handling without being affected by the variety in size, paper quality and the like of the apparatuses matter. Further, the conventional apparatuses require a large space for installation, and have a relatively low reliability.
SUMMARY OF THE INVENTION It is, therefore, an object of this invention to provide an improved automatic transport-direction reversing apparatus for flat articles, in which the transportdirection of the flat-article of a variety of sizes, paper qualities and others is unfailingly changed at high speed.
According to this invention, there is provided a transport-direction reversing apparatus for flat articles, in which the flat articles transported along feeding belts are guided to enter into a space between a pair of endless belts moving in the direction reverse to the flatarticle transport, and then the space is narrowed by pressing one of the endless belts sideways with respect to the motion of the belt by means of a movable roller, whereby the flat article is transported in the reverse direction.
BRIEF DESCRIPTION OF THE DRAWING The features and advantages of this invention will be better understood from the following detailed description of a preferred embodiment of this invention taken in conjunction with the accompanying drawing, wherein:
FIG. 1 is a perspective view of an embodiment of this invention; and
FIGS. 2(A), 2(B) and 2(C) show plan views illustrating the operation of the embodiment shown in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT stalled in a loop of the endless belt 17. The spacing D t of a gap C between the endless belts 16 and 17 is greater thanthickness of the thickest possible flat artiroller 21 is not actuated and remains in the state as shown in FIG. 2(A). Therefore, the distance D is greater than the thickness of the flat article. This allows the leading edge of the flat article to easily enter into the gap C. After a predetermined period of time from the passage of the trailing edge of the flat article between the lamp 15a and photodetector 15b, a signal is generated by which the moving roller 21 is actuated. This causes the moving roller 21 to press the endless belt 17 sideways so as to narrow the gap C and to hold the flat article by the endless belts 16 and 17, as shown in FIG. 2(B). At this moment, the trailing edge of the flat article Ma has passed by the roller 14. Furthermore, because the flat article Ma is pressed by the roller 18 and the moving roller 21, the trailing edge of the flat article for the transport direction A is pressed to the endless belt 17. Therefore, the flat article Ma is transported in the direction B by the endless belts 16 and 17. Then, the flat article Ma is fed by the endless belts l3 and 17 in the direction B, and the moving roller 22 is deactivated and returned to the initial state, as shown in FIG. 2(C). Thus, the transport direction of the flat article Ma is reversed from A to B. After the direction switching for the flat article Ma is accomplished, the following flat article Mb is fed to the gap C by the endless belts 10 and 13.
In this embodiment, because the movable roller 21 is activated in response to the detection of the trailing edge of the flat article, it is possible to handle the flat articles of a variety of sizes. Furthermore, this invention does not require the suction chamber needed in conventional apparatuses. Therefore, the installation of the apparatus of the present invention involves smaller amount of noise and space.
What is claimed is:
1. A transport-direction reversing apparatus for such flat articles as postal matter, comprising:
means for transporting a fiat article in a first transport direction;
means for detecting said flat article;
a pair of endless belts moving in a second direction substantially opposite to said first direction, the distance between said belts being greater than a thickness of the thickest flat article to be processed; and
moving roller means installed in a space surrounded by one of said endless belts for reducing said distance between said endless belts in response to said detecting means so that said flat article fed from said transporting means is transported by said endless belts.
2. A transport-direction reversing apparatus as recited in claim 1 wherein said means for detecting said flat article comprises a lamp and a photodetector on either side of said means for transporting a flat article in a first transport direction, said means for detecting being sensitive to the passage of said fiat article.
3. A transport-direction reversing apparatus as recited in claim 2 wherein said means for transporting a flat article in a first transport direction comprises a second pair of endless belts, the belts of said second pair 4 means for reducing the distance therebetween, and said fiat article is thereafter transported in said second direction by the contacting belts of saidfirst and second pairs of endless belts.
Claims (3)
1. A transport-direction reversing apparatus for such flat articles as postal matter, comprising: means for transporting a flat article in a first transport direction; means for detecting said flat article; a pair of endless belts moving in a second direction substantially opposite to said first direction, the distance between said belts being greater than a thickness of the thickest flat article to be processed; and moving roller means installed in a space surrounded by one of said endless belts for reducing said distance between said endless belts in response to said detecting means so that said flat article fed from said transporting means is transported by said endless belts.
2. A transport-direction reversing apparatus as recited in claim 1 wherein said means for detecting said flat article comprises a lamp and a photodetector on either side of said means for transporting a flat article in a first transport direction, said means for detecting being sensitive to the passage of said flat article.
3. A transport-direction reversing apparatus as recited in claim 2 wherein said means for transporting a flat article in a first transport direction comprises a second pair of endless belts, the belts of said second pair being in contact with one another and one of the belts of said second pair also contacting one of the belts of the first pair, wherEby said flat article is transported in said first direction by said second pair of endless belts, the transport direction of said flat article is reversed by the coaction of said first pair of endless belts and said means for reducing the distance therebetween, and said flat article is thereafter transported in said second direction by the contacting belts of said first and second pairs of endless belts.
