The present invention relates to a paper sheet taking out device for taking out a plurality of paper sheets such as a mailing sheet in sheet units.

A paper sheet taking out device so far known is a taking out device which takes out a plurality of pieces of mail in a vertical posture (for example, see Japanese Patent Laid-Open No. 2005-145671). This take-out apparatus has a mounting base where the lower edges of the paper sheets abut in a state where a plurality of paper sheets are stacked for mounting the plurality of paper sheets in a vertical posture, and a stacking direction of the paper sheets for feeding the paper sheets to the take-out position.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate the principles of the invention, together with the general description given above and the following detailed description of the embodiments thereof.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a plan view showing the paper taking out device 1 (hereinafter, simply referred to as taking out device 1) according to the first embodiment of the present invention from above, and Fig. 2 is a front view of the taking out device 1 of the present invention. to be. The take-out apparatus 1 of the present invention takes out one sheet at a time, for example, in order to feed a plurality of pieces of postal matter P put in one bundle to a processing zone of a back stage.

As shown in Fig. 1, the takeout apparatus 1 includes a feeding unit 10 for supplying a postal matter P to a takeout position, and a discharge unit 20 for releasing one piece of postal matter P delivered to a takeout position one by one. Has

The feeding unit 10 has a flat mounting base 2 in which the lower edges of the plurality of pieces of mail P put in a stacked state are in contact with each other to mount the plurality of pieces of mail in a vertical posture. A backup plate 3 is arranged at the right end of the mounting base 2 shown (i.e., the end spaced apart from the extraction position). The backup plate 3 is arranged in a substantially vertical direction across the mounting base 2 at substantially right angles.

The backup plate 3 presses the postal matter P in the arrangement direction of the postal matter, that is, the stacking direction (the direction of the arrow T1 in FIG. 1), and supplies all of the postal matter P in the direction of the arrow T1. As a result, the postal matter P present at the distal end portion in the feeding direction is fed to the take-out position at the left end of the mounting base 2 shown.

Two endless downstream bottom belts 4a and 4b (first and second bottom belts) are provided near the take-out position. The downstream bottom belts 4a and 4b are spaced apart from each other in a direction substantially crossing the feeding direction (the arrow T1 direction) of the postal matter P (in the direction of the arrow T2 in FIG. 1), and are arranged substantially parallel to each other, These belts extend along the feeding direction T1 of the postal matter P, respectively.

As shown in Fig. 2, the downstream bottom belts 4a and 4b are tension wound around the plurality of pulleys 5 and a portion of the bottom belt is exposed from the mounting base 2 toward the lower edge of the postal matter P. As shown in FIG. . In addition, the downstream bottom belts 4a and 4b are endlessly driven by one bottom motor 6, and a portion of the belt upwardly exposed from the mounting base 2 moves the mail P toward the take-out position. To contact the lower edge of the mail P.

In this embodiment, two pulleys 5a and 5b having different diameters are attached coaxially to the drive shaft 6a of the motor 6 and downstream along the take-out direction of the postal matter P (arrow T2 direction). The downstream bottom belt 4a (first bottom belt) disposed on the side is wound around the pulley 5a (first pulley) having a relatively large diameter, and downstream disposed on the upstream side in the direction of the arrow T2. The side bottom belt 4b (second bottom belt) is wound around the pulley 5b (second pulley) having a relatively small diameter.

That is, the diameters of the pulleys 5a and 5b for transmitting the driving force of the bottom motor 6 are different in order to vary the traveling speeds of the two downstream bottom belts 4a and 4b. Therefore, the feed force of the postal matter P by the downstream bottom belt 4a arrange | positioned downstream in the take-out direction T2 is set by the downstream bottom belt 4b arrange | positioned upstream in the take-out direction T2. It is set larger than the feeding power of the postal matter P. FIG. In the present specification, the feeding force is a force for feeding the postal matter P in the stacking direction, that is, a force for feeding the postal matter P in the takeout position, and the take-out roller 11 for describing the postal matter P at the distal end in the transfer direction. And the force (press use) pressurized onto the auxiliary roller 18.

In addition, one endless upstream bottom belt 7 is disposed between the two downstream bottom belts 4a and 4b. The upstream bottom belt 7 is tension wound around the plurality of pulleys 5 and is positioned so that a portion of the belt is exposed upward from the mounting base 2. This upstream bottom belt 7 is driven by the motor 8, and the exposed part moves toward the take-out position along the loading direction.

The downstream bottom belts 4a and 4b protrude upward from the upstream bottom belt 7 near the take-out position, and the postal matter P moved by the upstream bottom belt 7 is moved to the downstream bottom belts 4a and 4b. It moves to 4b) and moves. That is, the leaked portion of the downstream bottom belts 4a and 4b can move only a few pieces of mail P near the take-out position among the mails P mounted on the mounting base 2. On the other hand, the exposed portion of the upstream bottom belt 7 meets the lower edge of the post except for a few posts P adjacent to the take-out position among all posts P mounted on the mounting base 2. That is, the postal matter P adjacent to the backup plate 3 is moved by the upstream bottom belt 7 and is transferred to the downstream bottom belt 4 and fed to the take-out position.

The backing plate 3 is slidably attached to the shaft 9 extending along the feeding direction T1 of the postal matter P, and the vicinity of the lower end of the backing plate is connected to the upstream bottom belt 7. Further, the backup plate 3 moves along the shaft 9 in the feeding direction T1 of the postal matter P by the movement of the upstream side bottom belt 7. That is, the backup plate 3 is moved toward the take-out position by the motor 8 at the same speed as the upstream bottom belt 7.

The discharge unit 20 is disposed adjacent to the take-out position of the postal matter P. FIG. The discharge unit 20 has a take-out roller 11 which rotates in the take-out direction T2 in contact with the postal matter P fed to the take-out position by the feeding unit 10. As shown in Figs. 2 and 3A, the take-out roller 11 has a lower take-out roller 11a and a lower take-out roller 11a which rotate in contact with a portion near the bottom edge of the mail item P fed to the take-out position. ) Has a top take-out roller 11b disposed rotatably spaced apart from the top. As shown in Fig. 3A, the upper ejection roller 11b is spaced apart from the upper portion of the lower ejection roller 11a to such an extent that the upper ejection roller can contact the smallest postal matter Pmin to be operated by the ejection apparatus 1. Are arranged.

The take-out rollers 11a and 11b (hereinafter, commonly referred to as take-out rollers 11 in some cases) extend in a substantially vertical direction in which the rotation axes of the rollers cross at right angles with the directions T1 and T2, respectively, and the outer peripheral surface of the rollers The posts are arranged in contact with the surface of the postal matter P to rotate. The take-out roller 11 is disposed at a position inclined on the downstream side in the take-out direction T2 of the postal matter P so that the postal matter P of all sizes can be taken out. In addition, when the take-out roller 11 is rotated counterclockwise in FIG. 1, the mail P delivered to the take-out position substantially crosses the loading direction at right angles (in the direction of arrow T2 in FIG. 1) ( Hereinafter, the extraction direction is taken out, that is, in the upper direction in FIG.

The rotating shafts of the extraction rollers 11a and 11b are rotatably attached to the distal end of the first arm 12. The rotational distal end of the second arm 13 is rotatably attached to the proximal end of the first arm 12 and the torque control server motor 14 is attached to the proximal end of the second arm 13. At a substantially central portion of the first arm, the rotational end of the third arm 15 is rotatably attached. As a result, the take-out roller 11 can be moved in the feeding direction of the postal matter P, i.e., in a direction substantially parallel to the stacking direction, by this parallel link mechanism, and the roller is subjected to pressure based on the control of the servo motor 14. Is pressed onto the postal matter P which is fed to the take-out position.

In addition, the rotary shafts of the take-out rollers 11a and 11b are connected to the motor 17 via three timing belts 16a, 16b and 16c, and the motor 17 takes the take-out roller 11 in the take-out direction of the postal matter P. FIG. It is rotated in a predetermined direction so as to rotate.

Moreover, the auxiliary roller 18 is arrange | positioned in the position spaced apart from the take-out roller on the upstream side of the take-out roller 11 along the take-out direction T2 of the postal matter P feeding in the take-out direction. The auxiliary roller 18 has three roller portions 18a, 18b, and 18c arranged spaced apart from each other along the rotation axis of the auxiliary roller 18. The roller portions 18a, 18b, 18c are rotatable independently about a rotation axis extending in a substantially vertical direction, and the outer circumferential surface of the auxiliary roller contacts the surface of the postal matter P to rotate along the taken out postal matter P. Done. For example, as shown in Fig. 3B, in order to discharge a relatively large postal matter P, the auxiliary roller 18 has an upstream side along the takeout direction from the position where the takeout roller 11 is in contact with the postal matter P. FIG. Serves to support the mail (P).

 The axis of rotation of the auxiliary roller 18 is rotatably attached to the pivot end of the pivot arm 19. The pivot arm 19 rotates about an axis of rotation 19a disposed substantially in the center of the pivot arm. The proximal end of the revolving arm 19 is connected to a spring 19b for urging the revolving arm 19 about the axis of rotation 19a of the arm in the counterclockwise direction in the figure. That is, the swinging arm 19 presses the auxiliary roller 18b attached to the distal end of the swinging arm at a predetermined pressure onto the postal matter P fed to the ejection position.

Further, a feeding roller and a reversing roller (not shown) are arranged on the downstream side of the take-out direction T2 of the postal matter P fed to the take-out position. The feeding roller is disposed at a position such that the take-out roller 11 is rotatably in contact with the surface of the postal matter P to be taken out on the side where it is rotatably in contact with the postal matter. When the feeding roller rotates with the postal matter P held between the feeding roller and the reversing roller, the postal matter P is fed in the direction of the arrow T2. The reversing roller applies a separation torque to the postal matter P in the reverse direction of the take-out direction of the postal matter, and functions to separate the second and subsequent postal matters P after one piece of postal matter P taken out by the feeding roller.

The guide plate 21 is adjacent to the mounting base 2 on the rear surface of the feeding unit 10 described above, that is, on the downstream side (upper side in FIG. 1) of the mounting base along the take-out direction T2 of the postal matter P. FIG. Is placed in position. The guide plate 21 guides the distal end portion of the postal matter P in the take-out direction T2, wherein the postal matter is taken out by the backup plate 3, the upper bottom belt 7 and the downstream bottom rollers 4a and 4b. Is dispatched to. The guide plate 21 is slightly curved toward the downstream side in the ejection direction T2 near the ejection position of the postal matter P. FIG.

In addition, the above-mentioned discharge unit 20 has a guide plate 22 disposed to face the feeding unit 10 along the postal matter P fed to the take-out position by the feeding unit. The guide plate 22 has a plurality of openings (not shown) that expose the take-out roller 11 and the auxiliary roller 18 toward the feeding unit 10. As shown in FIG. 2, the guide plate 22 is slightly bent in the direction away from the feeding unit 10 near the roller portion 18c located on the uppermost side of the auxiliary roller 18. As shown in FIG. Therefore, even when the mail P mounted on the mounting base 2 in the vertical position falls onto the discharge unit 20 side, a part of the mail P near its upper end does not contact the guide plate 22. Do not.

4 and 5, the functions and effects of the extraction apparatus 1 of the first embodiment described above will be described.

In the above-described take-out apparatus 1, the diameter of the pulley 5a on which the downstream bottom belt 4a (hereinafter simply referred to as the bottom belt 4a) is wound is the downstream bottom belt 4b [hereinafter simply referred to as bottom belt ( 4b)] is set larger than the diameter of the wound pulley 5b. Of the two downstream bottom belts 4a and 4b of the feeding unit 10, the bottom belt 4a is disposed downstream in the takeout direction T2 of the postal matter P and the bottom belt 4b is taken out. It is arrange | positioned upstream by T2. In addition, since the two pulleys 5a and 5b are attached to the drive shaft 6a of one motor 6, a difference occurs between the traveling speeds of the two bottom belts 4a and 4b.

Specifically, the traveling speed (moving speed) of the bottom belt 4a is set higher than the traveling speed of the bottom belt 4b. As a result, the feeding power of the postal matter P by the bottom belt 4a becomes larger than the feeding power of the postal matter P by the bottom belt 4b, and the pressure between the take-out roller 11 and the postal matter P is the auxiliary roller. It is greater than the pressure between 18 and the mail P.

For example, if the traveling speed of the upstream side bottom belt 7 is V1, the traveling speed of the bottom belt 4a is V2, and the traveling speed of the bottom belt 4b is V3, as described above, the bottom belt 4a is The driving speed is higher than the traveling speed of the other bottom belts 7 and 4b (V1 = V3 <V2). Therefore, the postal matter P extending substantially parallel to the takeout direction T2 as shown in FIG. 4 is a position in which the distal end of the postal force is pressed onto the takeout roller 11 as shown in FIG. 5 in the takeout direction. Is changed to

Further, although not shown, according to the present embodiment, even when the postal matter P is inclined in the reverse direction (when the rear end of the postal matter P is in contact with the auxiliary roller 18 in the take-out direction), Even while the discharge operation is continued, the posture of the postal matter P is gradually changed as shown in Fig. 5 (so that the distal end of the postal matter P is pushed onto the takeout roller 11 in the takeout direction).

On the other hand, in the above-described conventional apparatus, the posture of the mail delivered to the take-out position is controlled to be substantially parallel to the take-out direction. Therefore, the pressure of the postal mail on the take-out roller becomes substantially the same as the pressure of the postal mail on the subsidiary roller, and the load resistance of the auxiliary roller along the taken-up postal mail acts greatly on the postal mail. Further, as in the conventional apparatus, when the posture of the postal mail is controlled to be substantially parallel in the take-out direction, the postal mail is easily in contact with the guide plate or the like. When the mail comes in contact with another member, a load resistance is created. If the load resistance acts on the mail in the reverse direction of the take-out direction in this manner, the discharge operation of the mail becomes unstable.

However, as in the take-out device 1 of the present invention, when the posture of the mail delivered to the take-out position is controlled to the above-described posture, the postal matter P can be separated from the auxiliary roller 18 (or weak force). Pressurized by the auxiliary roller 18] and the load resistance by the auxiliary roller 18 and the guide plate 22 can be reduced and the ejection force of the take-out roller 11 can be efficiently applied to the postal matter P and the postal matter. (P) can be taken out stably.

In this embodiment, the traveling speed V1 of the upstream side bottom belt 7 is set equal to the traveling speed V3 of the bottom belt 4b, and the traveling speed V2 of the bottom belt 4a is larger than the traveling speed. The set relationship V1 = V3 <V2 is obtained, but at least the traveling speed V2 of the bottom belt 4a is set higher than the traveling speed V3 of the bottom belt 4b and the running of the upstream bottom belt 7 The relationship V3 <V2 to which the speed V1 is not linked may be satisfied.

6 to 9, a paper sheet taking out device 23 (hereinafter referred to simply as taking out device 23) according to a second embodiment of the present invention will be described. The same reference numerals will be used for components that function in the same manner as the above-described extraction apparatus 1, and the detailed description thereof will be omitted.

As shown in Fig. 6, the take-out device 23 has two downstream bottom belts 24, 25 driven by the same motor 6 at the same traveling speed. In the above-described first embodiment, the diameters of the pulleys 5a and 5b are different from each other so as to vary the traveling speeds of the downstream bottom belts 4a and 4b. In this embodiment, the rotation shaft 6a of the motor 6 is different. The diameters of the two pulleys 5 attached to the same are the same and the two downstream bottom belts 24 and 25 run at the same speed.

Instead, in this embodiment, the coefficient of friction of the surface of the downstream bottom belt 24 (first bottom belt) (hereinafter simply referred to as the bottom belt 24) on the downstream side in the take-out direction of the postal matter P is referred to. Is set to be relatively larger than the coefficient of friction of the surface of the downstream bottom belt 25 (second bottom belt) (hereinafter simply referred to as the bottom belt 25) on the upstream side in the take-out direction of the postal matter P. FIG. Therefore, the frictional force (first frictional force) of the bottom belt 24 acting on the lower edge of the postal matter P is set to be greater than the frictional force (second frictional force) of the bottom belt 25 acting on the lower edge of the postal matter P. FIG. do. Therefore, the feeding force for feeding the postal matter P by the bottom belt 24 becomes relatively larger than the feeding force for feeding the postal matter P by the bottom belt 25.

For example, the gravity of the postal matter P acting on the bottom belts 24 and 25 is W, the friction coefficient of the surface of the bottom belt 25 is µ1, and the feeding force acting by the bottom belt 24 is F1, the bottom belt. Assuming that the friction coefficient of the surface of (25) is µ2 and the feeding force acting by the bottom belt 25 is F2, µ1> µ2. Therefore, F1 (= mu1 · W)> F2 (= mu2 · W).

When the friction coefficients of the bottom belts 24 and 25 are different in this manner, even when the traveling speed of the bottom belt 24 is the same as the traveling speed of the bottom belt 25, the feed force F1 of the bottom belt 24 is reduced. ) May be set relatively larger than the feed force F2 of the bottom belt 25. As a result, the pressing force between the take-out roller 11 and the postal matter P can be set relatively larger than the pressing force between the auxiliary roller 18 and the postal matter P. FIG.

That is, even when the postal matter P is fed to the takeout position in a posture substantially parallel to the takeout direction T2 as shown in FIG. 8, the postal matter at the distal end of the takeout direction T1 as shown in FIG. After P has been fed to the take out position, a part of the postal matter P at the takeout position near the distal end of the takeout direction T2 can be pressed relatively strongly onto the takeout roller 11 and the posture of the postal matter P May be changed as shown.

Also, although not shown, the posture of the postal matter P is not changed in some cases as shown in Fig. 9, but is fed by the bottom belt 24 acting on the portion of the postal matter P close to the distal end of the take-out direction. The force is relatively larger than the feeding force exerted by the bottom belt 25 acting on a part of the postal matter P close to the rear end in the take-out direction. Therefore, the load resistance by the auxiliary roller 18 acting on the postal matter P and the load resistance by the guide plate 22 can be reduced, and the ejection force of the take-out roller 11 is applied to the postal matter P with good efficiency. Release operation can be stabilized.

10 to 13, a paper sheet taking out device 31 (hereinafter referred to simply as taking out device 31) according to a third embodiment of the present invention will be described. The same reference numerals are used for components that function in the same manner as the extraction apparatus 23 of the second embodiment described above, and the detailed description thereof will be omitted.

As shown in Figs. 10 and 11, instead of varying the coefficients of friction of the surfaces of the bottom belts 24 and 25 in the above-described second embodiment, the ejection device 31 has a plurality of detent-type projections (profiles) ( 33 is arranged on the surface of the downstream bottom belt 32 (first bottom belt) (hereinafter simply referred to as bottom belt 32) which is downstream in the take-out direction. These protrusions 33 act on the lower edges of the postal matter P mounted on the mounting base 2, and the lower edges of each postal matter P are sandwiched between the protrusions 33 in the loading direction T1. Is moved. That is, also in this embodiment, the feeding power of the postal matter P by the bottom belt 32 becomes relatively larger than the feeding power of the postal matter P by the bottom belt 25 which has no projection at all.

Thus, for example, as shown in Fig. 12, even when the mail P is fed to the take-out position in a posture substantially parallel to the take-out direction T2, at the distal end of the feed direction T1 as shown in Fig. 13. After the postal matter P is fed to the takeout position, a part of the postal matter P in the takeout position near the distal end of the takeout direction T2 can be pressed relatively strongly onto the takeout roller 11 and the postal matter P The posture of may be changed as shown.

Therefore, also in this embodiment, in the same manner as in the above-described second embodiment, the pressing force between the postal matter P and the take-out roller 11 is relatively larger than the pressing force between the postal matter P and the auxiliary roller 18. Can be set. The load resistance by the auxiliary roller 18 acting on the postal matter P and the load resistance by the guide plate 22 can be reduced and the ejection force of the take-out roller 11 can be applied to the postal matter P with good efficiency. Release work can be stabilized.

14 to 17, a paper sheet taking out device 41 (hereinafter referred to simply as taking out device 41) according to a fourth embodiment of the present invention will be described. The same reference numerals are used for components that function in the same manner as the extraction apparatus 23 of the second embodiment described above, and the detailed description thereof will be omitted.

As shown in Figs. 14 and 15, instead of varying the coefficients of friction of the surfaces of the two downstream bottom belts 24 and 25 in the above-described second embodiment, the take-out device 41 has a downstream side in the take-out direction. Downstream bottom belt 42 (second bottom belt 42) (hereinafter simply referred to as bottom belt 42) in the width along the downstream side bottom belt 25 (second side) in the upstream side in the take-out direction Bottom belt) (hereinafter simply referred to as bottom belt 25).

As such, the width of the bottom belt 42 is set to be relatively larger than the width of the bottom belt 25 so that the length of the bottom belt 42 coming into contact with the lower edge of the postal matter P is set relatively large, and the postal matter P The frictional force acting on the lower edge of the can be relatively large. Therefore, also in this embodiment, the feeding power of the postal matter P by the bottom belt 42 becomes relatively larger than the feeding power of the postal matter P by the bottom belt 25.

Thus, for example, as shown in Fig. 16, even when the postal matter P is fed to the take-out position in a posture substantially parallel to the take-out direction T2, at the distal end portion of the feed direction T1 as shown in Fig. 17. After the postal matter P is fed to the takeout position, a part of the postal matter P in the takeout position near the distal end of the takeout direction T2 can be pressed relatively strongly onto the takeout roller 11 and the postal matter P The posture of may be changed as shown.

As a result, even in the case of this embodiment, in the same manner as in the above-described second embodiment, the pressing force between the postal matter P and the take-out roller 11 is relatively higher than the pressing force between the postal matter P and the auxiliary roller 18. It can be set large. The load resistance by the auxiliary roller 18 acting on the postal matter P and the load resistance by the guide plate 22 can be reduced and the ejection force of the take-out roller 11 can be applied to the postal matter P with good efficiency. And the release operation can be stabilized.

18 to 21, a paper sheet taking out device 51 (hereinafter referred to simply as taking out device 51) according to a fifth embodiment of the present invention will be described. The same reference numerals are used for components that function in the same manner as the extraction apparatus 23 of the second embodiment described above, and the detailed description thereof will be omitted.

As shown in Figs. 18 and 19, instead of varying the coefficients of friction of the surfaces of the two bottom belts 24 and 25 in the second embodiment described above, the take-out device 51 is located downstream in the take-out direction. The friction coefficient and width of the surface of the downstream side bottom belt 52 (first bottom belt) (hereinafter simply referred to as bottom belt 52) are downstream side bottom belt 25 (second side) in the upstream side in the extraction direction. Bottom belt) (hereinafter simply referred to as bottom belt 25) is set equal to the friction coefficient and width. In addition, an elongate strip-shaped friction member 53 is disposed adjacent to the bottom belt 25.

The friction member 53 functions to exert a predetermined frictional force on the lower edge of the postal matter P mounted on the mounting base 2 in a vertical posture and extends along the feeding direction T1 of the postal matter P. FIG. do. In particular, the friction member 53 is disposed at a position facing the auxiliary roller 18 which is a main factor for the load resistance acting in the reverse direction of the take-out position of the postal matter P, but is slightly spaced apart from the guide plate 22. . That is, the friction member 53 is disposed to exert a frictional force in the reverse direction of the feeding direction T1 with respect to the lower edge of the postal matter P fed toward the take-out position and is fed by the bottom belt 25 adjacent to the friction member. It weakens the force.

On the other hand, when the friction member 53 extends to the take-out position, when the postal matter P delivered to the take-out position is taken out from the takeout position in the direction of the arrow T2, the friction force applied in the reverse direction of the takeout direction is the postal matter P. It is generated upstream in the extraction direction of, causing disadvantages contrary to the scope of the present invention. Therefore, in the present embodiment, the friction member 53 is disposed at a position spaced apart from the guide plate 22 to prevent the postal matter P to be ejected from the ejection position from colliding with the friction member 53, which is undesirable. The load resistance is prevented from being applied to the postal matter P to be taken out in the direction of the arrow T2.

When the feeding by the bottom belt 25 is weakened as described above, the feeding force applied by the bottom belt 25 (friction member 53) on the upstream side in the take-out direction is the postal matter P at the take-out position. It can be set smaller than the feeding force applied by the bottom belt 52 on the downstream side in the take-out direction of. In the same manner as in the above-described embodiment, the pressure between the postal matter P and the take-out roller 11 can be set relatively higher than the pressure between the postal matter P and the auxiliary roller 18 and acts on the postal matter P. FIG. The load resistance by the auxiliary roller 18 and the load resistance by the guide plate 22 can be reduced and the discharge force of the take-out roller 11 can be applied to the postal matter P with good efficiency and the discharge operation can be stabilized. Can be.

Thus, for example, as shown in Fig. 20, even when the postal matter P is fed to the takeout position in a posture substantially parallel to the takeout direction T2, the postal matter P is moved to the takeout position as shown in Fig.21. As it is fed, the posture of the postal matter P can be changed and a part of the postal matter P in the takeout position near the distal end portion of the takeout direction T2 can be pressed relatively strongly onto the takeout roller 11. As a result, the load resistance by the auxiliary roller 18 acting on the postal matter P and the load resistance by the guide plate 22 can be reduced, and the ejection force of the take-out roller 11 can reach the postal matter P with good efficiency. Can be applied and the release operation can be stabilized.

22 to 25, a paper sheet taking out device 61 (hereinafter simply referred to as taking out device 61) according to a sixth embodiment of the present invention will be described. The same reference numerals will be used for components that function in the same manner as the above-mentioned extraction apparatus 1 of the first embodiment, and detailed description thereof will be omitted.

As shown in Figs. 22 and 23, the ejection device 61 of this embodiment is a downstream bottom belt 4a (first bottom belt) (hereinafter simply referred to as a bottom belt 4a) which is downstream in the ejection direction. A bottom motor 62 (first motor) for driving a bottom motor 4b (second bottom belt) (hereinafter simply referred to as a bottom belt 4b) on an upstream side in the ejection direction; 63) (second motor).

In other words, the ejection device 61 of the present embodiment has two bottom motors 62 and 63 for independently driving two downstream bottom belts 4a and 4b. That is, in the above-described first embodiment, one motor 6 is used and the running speeds of the downstream bottom belts 4a and 4b are changed by varying the diameters of the pulleys 5a and 5b. The bottom motors 62 and 63 are driven independently to vary the running speed of the bottom belts 4a and 4b.

For example, if the traveling speed of the upstream side bottom belt 7 is V1, the traveling speed of the bottom belt 4a is V2, and the traveling speed of the bottom belt 4b is V3, as described above, the bottom belt 4a is The driving speed is higher than the traveling speed of the other bottom belts 7 and 4b (V1 = V3 <V2). Thus, as shown in Fig. 24, the postal matter P substantially parallel to the takeout direction T2 is changed to a position in which the distal end of the postal matter is pressed onto the takeout roller 11 in the takeout direction.

Further, although not shown, according to this embodiment, even when the postal matter P is inclined in the reverse direction (the posture of the rear end portion of the postal matter P in contact with the auxiliary roller 18 in the take-out direction) is released. As the operation continues, the posture of the postal matter P is gradually changed as shown in Fig. 25 (so that the distal end of the postal matter P is pushed onto the takeout roller 11 in the takeout direction).

As described above, also in this embodiment, effects similar to those of the above-described first embodiment can be produced. That is, the traveling speeds of the bottom belts 4a and 4b can be different so that the mail P can be separated from the auxiliary roller 18 (or the mail can be pressurized with the same force). The load resistance by the 18 and the guide plate 22 can be reduced and the ejection force by the take-out roller 11 can be applied to the postal matter P with good efficiency and the postal matter P can be stably taken out. .

In this embodiment, the traveling speed V1 of the upstream side bottom belt 7 is set equal to the traveling speed V3 of the bottom belt 4b, and the traveling speed V2 of the bottom belt 4a is higher than the traveling speed. Although the set relationship is obtained (V1 = V3 <V2), the traveling speed V2 of the bottom belt 4a is set higher than the traveling speed V3 of the bottom belt 4b and the traveling speed of the upstream bottom belt 7 is obtained. The relationship V3 <V2 to which (V1) is not linked may be satisfied.

26 and 27, a paper sheet taking out device 71 (hereinafter referred to simply as taking out device 71) according to a seventh embodiment of the present invention will be described. The same reference numerals will be used for components that function in the same manner as the extraction device 61 of the sixth embodiment described above, and detailed description thereof will be omitted.

As shown in Figs. 26 and 27, the ejection device 71 is pushed out by the ejection roller 11 projecting from the guide plate 22 toward the ejection position by a value exceeding a predetermined threshold in the direction of the arrow T1. Is a second detection unit for detecting whether the first detection unit 72 for detecting and the auxiliary roller 18 protruding from the guide plate 22 toward the ejection position are pushed to a value exceeding a predetermined threshold in the direction of the arrow T1. Has (73). The take-out device 71 also has a control section 74 for driving and controlling two bottom motors 62 and 63. The extraction apparatus 71 of this embodiment has a structure similar to the extraction apparatus 61 described above except that these two detection units 72 and 73 and the control unit 74 are arranged.

The first detection unit 72 is arranged to detect whether there is a postal matter P near the guide plate 22 near the take-out roller 11. In this embodiment, the projected position of the take-out roller 11 is detected by the encoder 72 provided in the servo motor 14 to press the take-out roller 11 toward the postal matter P. FIG. That is, in this embodiment, the servo motor 14 also acts as the first detector 72.

The second detection unit 73 is arranged to detect whether there is a postal matter P near the guide plate 22 near the auxiliary roller 18. In this embodiment, the photo reader 73 detects whether or not the pivot arm 19 to which the rotational axis of the auxiliary roller 18 is rotatably attached is rotated at a specific rotational position. Thus, the auxiliary roller 18 detects whether the auxiliary roller 18 is pushed to a value higher than the predetermined threshold value.

In this embodiment, an encoder is used as the first detection unit 72, but a photo reader may be used, and a proximity sensor may be used. In the following description, when the take-out roller 11 and the auxiliary roller 18 are pushed to a value higher than a specific threshold by the postal matter P, the first and second detection units 72 and 73 are turned on. The first and second detectors are turned off when the postal matter P is separated from the guide plate 22.

Hereinafter, with reference to the flowchart of FIG. 28 and the operation explanatory drawing of FIGS. 29-32, the operation | movement of the extraction device 71 mentioned above is demonstrated. At this time, it is assumed that the traveling speed of the upstream bottom belt 7 is V1, the running speed of the upstream bottom belt 4a is V2, and the running speed of the downstream bottom belt 4b is V3.

When a plurality of pieces of postal matter P are put into the take-out apparatus 71 and start the feeding operation as the object to be processed (step 1 in Fig. 28), the control section 74 is the downstream side bottom belt 4a located downstream in the take-out direction. Is driven at a traveling speed higher than the upstream bottom belt 7 and the downstream bottom belt 4b (general speed: V1 = V3 < V2).

 Thereafter, the control unit 74 checks the state of the postal matter P delivered to the take-out position via the first detection unit 72 and the second detection unit 73 (step 2), and shown in FIGS. 29 to 32. One of the states is determined (step 3). Further, based on the determination result, the bottom motor 62 (first motor) and the bottom motor 63 (second motor) are driven and controlled, and the driving of the bottom belt 4a and the bottom belt 4b is controlled. (Step 4).

Thereafter, the process from Steps 2 to 4 is repeated (Steps 2 to 4) until there is no postal matter P as the object to be fed on the mounting base 2 (Step 5: Yes), thereby completing the feeding operation. do. Although not shown in the flowchart of Fig. 28, the upstream bottom belt 7 repeats driving and stopping in the same manner as the bottom belt 4a.

More specifically, as shown in FIG. 29, when the postal matter P is separated from the take-out roller 11 and the auxiliary roller 18, that is, the first detection unit 72 and the second detection unit 73 are each turned-off. When turned off, the bottom belt 4a is operated at a running speed higher than the bottom belt 4b (V2 > V3). Therefore, when the bottom belts 4a and 4b continue to be driven as before, as shown in Fig. 30, the posture is such that a part of the postal matter P close to the distal end portion in the ejection direction is pressed onto the ejection roller 11. Is changed.

In addition, when it is determined in the above-described step 3 that the postal matter P has the posture shown in Fig. 30, that is, when only the first detection unit 72 is turned on, the posture of the postal matter P is appropriate, and therefore The bottom belts 4a and 4b are stopped.

Further, when it is determined in the above-described step 3 that the postal matter P has the posture shown in Fig. 31, that is, only the second detection unit 73 is turned on, the bottom belt 4a (and the upstream bottom belt) (7) is driven to press the distal end portion of the postal matter P onto the takeout roller 11 in the takeout direction. At the same time, in order to reduce the load resistance applied from the auxiliary roller 18 to the postal matter P, the bottom belt 4b facing the auxiliary roller 18 is reversed. According to this operation, the postal matter P is changed from the posture shown in FIG. 31 to the posture shown in FIG.

In addition, when the postal matter P is determined to have the posture shown in FIG. 32 in step 3 described above, that is, when both the first and second detection units 72 and 73 are turned on, the postal matter close to the distal end portion in the take-out direction. The portion of P is already pressed onto the take-out roller 11. Thus, the bottom belt 4a (and the upstream bottom belt 7) are stopped. At the same time, in order to reduce the load resistance applied from the auxiliary roller 18 to the postal matter P, the bottom belt 4b facing the auxiliary roller 18 is reversed. According to this operation, the postal matter P is changed from the posture shown in FIG. 32 to the posture shown in FIG.

As described above, according to this embodiment, the load resistance applied from the auxiliary roller 18 and the guide plate 22 to the postal matter P is reduced, regardless of the posture of the postal matter P introduced into the take-out apparatus 71. The ejection force of the take-out roller 11 can be applied to the postal matter P with good efficiency.

In this embodiment, the driving of each of the bottom motors 8, 62, 63 is such that the traveling speed V1 of the upstream side bottom belt 7 is set equal to the traveling speed V2 of the bottom belt 4b and the bottom bell The travel speed V3 of the track 4a is controlled to be set higher than the travel speed (V1 = V3 < V2). However, at least the traveling speed of the bottom belt 4a on the downstream side in the take-out direction of the postal matter P can be set higher than the traveling speed of the bottom belt 4b on the upstream side (V3 < V2), and the upstream bottom The running speed V1 of the belt 7 is not linked. In this embodiment, the work (drive or stop timing) of the upstream bottom belt 7 is matched to the work of the bottom belt 4a, but the work timing of the upstream bottom belt 7 is the work timing of the bottom belt 4b.
