Benefits of technology

[0006] An object of the present invention is to provide a sheet take-out apparatus for surely correcting the posture of paper-like materials by a simple constitution and stably taking out paper-like materials.

Problems solved by technology

However, in the aforementioned conventional take-out apparatus, the driving mechanism for the lever to be inserted between postal matter is complicated and a problem arises that the cost is increased.
Further, when the lever causes malfunctions, postal matter may be damaged.

operation example 1

[0052] When the tolerance of the take-out position in the conveying direction where postal matter P can be stably taken out is assumed as buffer B, the moving speeds of floor belts 4 and 7 can be expressed as a function of buffer B, the projection position of each of rollers 11a, 11b, 16a, and 16b respectively detected via sensors 13a, 13b, 18a, and 18b mentioned above, and processing speed K [sheets / h] of take-out apparatus 1. Further, assuming the projection position of each of take-out rollers 11a and 11b detected via sensors 13a and 13b as P1, the projection position of each of auxiliary rollers 16a and 16b detected via sensors 18a and 18b as P2, and the tilt angle of postal matter P supplied to the take-out position as L, the moving speed functions of floor belts 4 and 7 are expressed by the following formulas (1) to (3).

V1=f(L, V2)  (1)

V2=f(B, K)  (2)

B=f(P1, P2, L)  (3)

[0053] When controlling V1 and V2 on the basis of the formulas (1) to (3) and grouping possible cases, a ...

operation example 2

[0064] Here, it is premised to guide a user by handling precautions and serviceman's explanation so as to preset postal matter P in a forward falling state (the state shown in FIG. 4) in take-out apparatus 1 and control not to set postal matter P in a backward falling state (the state shown in FIG. 5) and in an upright state. Further, on the assumption of such control, moving speed V1 of lower-stream side floor belt 4 is not made lower than moving speed V2 of upstream side floor belt 7. Namely, postal matter P is all set in a forward falling state, so that a case of an occurrence of backward falling may not be considered. On the other hand, as explained in operation example 1, when correcting the posture of backward falling, there is the possibility that according to the state of postal matter P, the take-out operation by take-out roller 11 may be stopped temporarily. However, in operation example 2, it is not required, so that the reduction in the processing speed due to the tempor...

operation example 3

[0067] Here, the projection positions of two take-out rollers 11a and 11b are detected by sensors 13a and 13b and the falling state of postal matter P is detected by take-out roller 11. Therefore, the posture of postal matter P is detected at four locations of two take-out rollers 11a and 11b and two auxiliary rollers 16a and 16b in total as a projection position of each roller and all the postures of postal matter P can be detected accurately.

[0068] In this case, the control operation by take-out apparatus 1 can be explained basically by adding detection angle Lp by take-out roller 11 to the relational expression in operation example 1 mentioned above. The functions at this time are expressed by the following formulas (4) to (6).

V1=f(L, Lp, V2)  (4)

V2=f(B, K)  (5)

B=f(P1, P2, L, Lp)  (6)

[0069] Further, a control table at this time can be obtained by adding Lp to the table of operation example 1 mentioned above. The control table in operation example 3 is shown in Tables 3a and ...

Abstract

A sheet take-out apparatus has a table for loading a plurality of postal matter upright, a backup plate for pressing postal matter in the stacking direction and supplying them to a take-out position, a lower stream side floor belt installed so as to be partially exposed from the table in the neighborhood of the take-out position, an upper stream side floor belt, a take-out roller, and two auxiliary rollers. A difference in the projection position between the auxiliary rollers pressed by the postal matter supplied to the take-out position is detected and the inclination of the postal matter is detected. And, on the basis of the detection results, the moving speeds of the floor belts are controlled so as to correct the posture of the postal matter upright.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2003-387199, filed Nov. 17, 2003, the entire contents of which are incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to a sheet take-out apparatus for taking out a plurality of paper-like materials particularly such as postal matter one by one. BACKGROUND OF THE INVENTION [0003] Conventionally, as a sheet take-out apparatus, as described in Japanese Patent Application Publication No. 2002-68490, an apparatus for taking out a plurality of postal matter one by one in an upright state. This take-out apparatus has two sets of floor belts that make contact with the lower end sides of a plurality of postal matter dropped side by side and are extended in the lining direction of the postal matter. The postal matter is transferred by the two sets of floor belts, is moved to the take-out position...
