Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to paper sheets called stickers, cards, tickets, etc. made of paper, plastic, etc., which are sent out for automatic sales, etc. The present invention relates to a method and device for sending out the same.

(Prior technology) It was developed in the 1980s as a device for feeding paper sheets one by one.
This is disclosed in Japanese Patent Application Laid-open No. 104966 (first example) and Japanese Patent Application Laid-Open No. 167143/1983 (second example).

In the prior art of the first example, the front part of the paper sheets stacked in the case is supported by a delivery roller, and the rotation of the delivery roller moves the paper sheets from below the front screen plate to the lowest paper sheet. It is configured to send out the types one by one forward.

In the second example of the prior art, the loaded paper sheets are placed on a push-out member, the lowest paper sheets are pushed out by the push-out step at the rear upper part of the push-out member, and the paper sheets higher than that are pushed out by a screen plate. Preventing movement. A guide surface facing forward and downward is formed at the lower part of the rear surface of the screen plate, and this guide surface abuts at the same time as the tips of the various sheets of paper.

(Problem to be solved by the invention) Paper sheets are very thin and tend to adhere to each other due to oil film or static electricity on the surface. The weight of the higher-ranking paper sheets is added to the paper sheets, and the paper sheets are compressed and become thinner, reducing the accuracy of single-sheet feeding.

In the first example, a gap for one paper sheet is provided between the lower end of the screen plate and the feed roller, and the screen plate prevents all sheets except the lowest one from being fed. The screen plate does not have the strength to peel off the adhered paper sheets, and if the paper sheets become thin or deformed due to the load, two-sheet feeding will occur immediately.

In addition, in the second example, since the lowest paper sheet is sent out from the rear at the stepped portion of the sliding extrusion member, even if the paper sheet is attached, it can be peeled off and sent out one by one. However, it is difficult to apply this method to very thin sheets, such as damaging the upper sheet during the return stroke of the extrusion member or causing the sheets to have different wall thicknesses. The screen board is formed with a front downward guiding surface, which presses the first sheet with the second or higher sheet to prevent the leading edge of the sheet from floating up. It is not possible to actively separate the leading end from the second or more sheets, and on the contrary, there is a possibility of promoting the delivery of two sheets.

The present invention solves the problems of these conventional techniques and processes paper sheets with extremely high precision, even if the paper sheets are extremely thin, even if the top and bottom are stuck together, or even if weight is added from above. An object of the present invention is to provide a method and device for feeding out paper sheets one by one.

(Means for Solving the Problems) The specific means in the method of the present invention for solving the problems is to bring a delivery roller 3 into contact with the laminated paper sheets A, and rotate the delivery roller 3.
The first paper sheet A that is in contact is fed out while being in contact with the inclined guide surface 10 of the screen plate 5, and at the time of this feeding, the paper surface of the paper sheet A is deformed into a curved shape in the vertical direction when viewed from the front in the moving direction. A paper sheet feeding method, wherein when the paper sheet A is deformed into a vertically curved shape when viewed from the front in the moving direction, the paper surface is also deformed into a vertically curved shape when viewed from the side in the moving direction. In addition, the first specific means of the apparatus of the present invention is that the front part of the paper sheets A is placed in a storage case 2 that stores the paper sheets A in a stacked manner, and the front part of the paper sheets A is rotated. A delivery roller 3 that sends out the lowest paper sheet A forward, and a paper that is erected in front of the stacked paper sheets A in front of this delivery roller 3 in the feeding direction and that is the second or higher sheet from the bottom. A screen plate 5 that prevents the paper sheets A from being sent out, and a guide stand 9 that guides the paper sheets A sent out from the screen plate 5 forward and upward are provided. A guide surface 10 that is inclined forward and downward is formed to guide the leading edge of the lower paper sheet A to the front and downward. The paper sheet feeding device is formed in an uneven shape to curve the paper sheet, and the feeding roller 3
The upper part of the screen and the upper surface of the guide stand 9 are the lower end surface 5a of the screen plate.
Paper sheet A that comes into contact with these at the same time as it comes into contact with
In order to curve vertically in the side view of the moving direction, the upper part of the feed roller 3 is located at the upper rear of the lower end surface 5a, and the upper surface of the guide table 9 extends from below the lower end surface 5a toward the front and upper side. In addition,
The second specific means of the device is that the front part of the paper sheets A is placed in a storage case 2 that stores the paper sheets A in a stacked manner, and by rotating, the lowest sheet A is moved forward. A feed-out roller 3 that sends out the paper sheets A, and a roller 3 that is erected in front of the stacked paper sheets A in front of the feed-out roller 3 in the feed direction and prevents the second or more sheets A from being sent out from the bottom. A screen board 5, a guide stand 9 that guides paper sheets A sent out from the screen board 5 forward and upward;
A receiving surface 18 for receiving the rear part of the stacked paper sheets A is provided, and a front-downward inclined guide is provided on the lower rear surface of the screen plate 5 to guide the leading edge of the lowest paper sheet A to be sent forward and downward. A paper sheet feeding device is provided with a surface 10, and the lower end surface 5a of the screen plate 5 is formed in an uneven shape to curve the feeding paper sheet A in the vertical direction when viewed from the front in the moving direction. The upper part of the feed roller 3 is placed at a height halfway between the upper and lower ends of the guide surface 10 of the screen plate 5, and a protrusion 13 is formed on the rear surface of the screen plate 5 to slightly shift the upper sheet A to the rear. A holding guide portion 17 is formed above the surface 18 for holding the rear portion of the superior sheet A that has been shifted rearward.

(Function) When the delivery roller 3 is rotated, the lowest sheet A loaded in the case 2 is sent forward, and its leading edge is free on the front downward guiding surface 10 of the screen plate 5. They touch each other and move while curving downward. The second and higher sheets A hit the screen plate 5 above the guide surface 10 and are separated from the lowest sheet A1.

When the second paper sheet A2 was not separated,
The two lower sheets A1 and A2 move forward and downward while slidingly contacting the guide surface 10, and the lower end surface 5a of the screen plate 5
has an uneven shape, and the frictional resistance of the sliding contact of the tip of paper sheet A during transfer is on the lower side A1 is on the upper side A1
2, a separation force acts on the upper and lower paper sheets A1, and when the lower paper sheet A1 comes into contact with the lower end surface 5a, its leading edge is curved downward, and the paper sheet A1 After the tip of type A passes through the lower end surface 5a, it is guided by the guide table 9 that is inclined from below to the front and upper side, and is curved upward, so that the midway portion thereof is curved into a downwardly convex shape when viewed from the side in the direction of movement. Further, since the paper sheet A is pressed against the lower end surface 5a in a state of being curved in the vertical direction when viewed from the side, and is also curved in an uneven shape when viewed from the front in the direction of movement, the lower paper sheet A squeezing force is applied to the paper sheet A1 in the longitudinal and lateral directions, and a force is applied to the upper paper sheet A2, which does not reach the lower end surface 5a and remains in a horizontal position, to separate it, thereby making it possible to feed out one sheet more reliably. It will be done.

In addition, the rear of the loaded paper sheets A is received by the receiving guide part 17 of the upper one, so that much weight is not added to the lower one, and the rear part is stably supported by the partially flat receiving surface 18. It is accepted. The weight of the lowest sheet A is lighter than that of the upper sheet A, and the resistance at the start of feeding is small, and when the trailing edge leaves the receiving surface 18, the weight of the sheet A is 2. The sheet is separated from the sheet A, the frictional resistance becomes extremely small, and the receiving roller 8 only prevents drooping.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the embodiment shown in FIGS. 1 to 7, reference numeral 1 denotes a paper sheet feeding device built into a sticker vending machine or the like, and there are dozens of sheets in a case 2 having left and right side walls 2a and a back plate 2b formed of sheet metal or the like. Paper sheets A ranging from one sheet to several hundred sheets are stored in a stack, and a feed roller 3 and a receiving member 4 are arranged at the bottom thereof, and a screen plate 5 is erected in front of it.

The delivery roller 3 is provided on a delivery roller shaft 6 pivotally supported by the case 2 in order to receive the front part of the loaded paper sheets A, and is made of rubber, sponge, or a metal roller with a rough surface. A rotating member 7 such as a gear, a rubber roller, or a sprocket is provided at the outer end of the delivery roller shaft 6 to which driving force is transmitted from a handwheel or an electric motor. Behind this delivery roller 3 is a receiving roller 8.
However, at the front, guide stands 9 that are inclined forward and upward are arranged.

The lower part of the screen plate 5 is located at a distance above and in front of the delivery roller 3, and on the rear surface of the lower part, a guide surface 10 is formed which is inclined forward and downward at an inclination angle α of 30 to 70 degrees with respect to the perpendicular line. , the upper end 10a of this guide surface 10, that is, the lower end of the side surface of the stacked paper sheets of the screen plate 5, is higher than the delivery roller 3 by a height H, and this height H is larger than the wall thickness t of the paper sheets A. It is smaller than 2 tons for two sheets, and the lower end of the guide surface 10, that is,
The lower end surface 5a of the screen plate 5 is located below the upper part of the delivery roller 3 by a distance h.

Therefore, as shown in FIG.
The paper sheet A 1 at the lowest level contacts the screen plate 5 above the upper end 10 a and is prevented from being fed out, and the lowest paper sheet A ₁ contacts the screen plate 5 below the upper end 10 a and is deflected downward while slidingly contacting the guide surface 10 . It is transformed in the longitudinal direction from a horizontal position to a forward downward curved position.

Further, the lower end surface 5a of the screen plate 5 has fifth and sixth
As shown in the figure, it is formed into a downwardly convex circular arc surface within the width when viewed from the front, and intersects with the guide surface 10, making the lower end of the guide surface 10 downwardly convex.

After the lower paper sheet A1 passes under the lower end surface 5a while being in contact with the lower end surface 5a, it is guided by the upper surface of the guide table 9 and moves upward from the lower end surface 5a while curving, as shown in FIGS. 2 and 4. Then, it curves into a downwardly convex shape when viewed from the side in the direction of movement, and since the direction of curvature changes, a strong squeezing force is applied.

Further, since the leading end of the lower paper sheet A1 curves downward and comes into elastic contact with the lower end surface 5a, when it reaches the guide stand 9, the feed roller 3 and the guide stand 9
Because it is pressed against the lower end surface 5a between the fourth and
As shown in Figure 6, approximately along the lower end surface 5a,
It curves into a downwardly convex shape when viewed from the front in the moving direction, and further squeezing force is applied, and the lower paper sheet A
As the left and right sides of the paper sheet 1 spring up, a force is exerted to push up the upper paper sheet A2, and the almost entire length of the paper sheet A is fed out, which acts to loosen the adhesion state. A bending means D is formed between the guide surface 10 and the upper surface of the guide stand 9 for further bending the paper sheet A which is curved in the vertical direction when viewed from the side in the vertical direction when viewed from the front.

8 and 9 show two modified examples of the lower end portion of the screen plate 5, and the lower end surface 5a constituting the bending means D.
The shape is not limited to a downwardly convex shape, but is also a downwardly concave shape as shown in Fig. 8, in other words, a downwardly convex shape at both left and right ends, or a shape in which only the center in the left and right direction protrudes downwardly as shown in Fig. 9. It's okay to be. This downwardly projecting portion may form an independent projecting member, and this projecting member may be fixed to the lower part of the screen plate 5. Note that the corner 1 between the lower end surface 5a and the guide surface 10
1, it is preferable to provide a chamfered radius in order to make the transfer of the paper sheets A smooth.

Forming the lower end surface 5a of the screen plate 5 in an uneven shape also changes the shape of the front downward guide surface 10. That is, when the lower end surface 5a is horizontal, the guide surface 1
0 has the same width over the entire length in the left and right direction, but by making it uneven, the width differs between the center part and both sides in the left and right direction, and the leading edge of the paper sheet A and the guide surface 10 The length of contact with the guide surface 1 becomes shorter as it goes downward, and the frictional resistance during sliding contact also decreases.
It is large at the top of 0, and is minimum at the bottom. Therefore, in the case of double-layered sheets A, the magnitude of the frictional resistance that the upper and lower sheets A receive are completely different, and the frictional resistance is large from the guide surface 10. The upper sheet A2 which does not receive the feeding force from the feeding roller 3 is the lower sheet A2.
A ₁ cannot be attached to it.

A step portion 12 is formed on the rear surface of the screen plate 5 above the guide surface 10, and the portion above the step portion 12 is a protrusion 13. Due to this protrusion 13, more than, for example, 10 to 20 of the stacked paper sheets A are slightly shifted rearward.

The receiving member 4 that receives the rear part of the loaded paper sheets A has attachment parts 14 at both left and right ends welded or bolted to the case 2, and one or more tongue pieces 15 are provided in the middle in the left and right direction. The tongue piece 15 is formed with a vertical wall portion 16 and a holding guide portion 17 that slopes rearward and upward from the upper end of the wall portion 16.

The receiving surface 18 of the receiving member 4 is set at the same height or slightly higher than the upper part of the delivery roller 3, and is also set slightly higher than the receiving roller 8, and partially receives the rear part of the paper sheet A. There is. In addition, the holding guide section 1
The lower end of 7 is at the same height as the stepped portion 12 or slightly lower, and the distance from the wall portion 16 to the protrusion 13 is shorter than the front-to-back length of the paper sheet A by the depth of the stepped portion 12. It's summery.

For this reason, paper sheets AP lower than the stepped portion 12 have their rear ends held by the receiving surface 18, while paper sheets AQ higher than the stepped portion 12 have their rear ends received by the receiving surface 17. , and the upper sheet AQ is shifted forward by the holding guide section 17 when descending.

Therefore, the entire weight of the stacked paper sheets A is applied to the delivery roller 3 on the front side, but the weight is applied to the receiving surface 1 on the rear side.
8, only the weight of the lowest sheet AP is added to the sheet A1, and the weight applied to the rear end of the lowest sheet _A1 that is about to be sent out is significantly reduced, and even if the number of loaded sheets A increases The delivery resistance remains light and small and remains approximately constant.

The receiving roller 8 prevents the rear end of the paper sheet A to be sent out from hanging down after leaving the receiving surface 18, and the guide stand 9 guides the front end of the paper sheet A to be sent out to the outlet. It is something to do. 22 indicates a weight, and 23 indicates the trajectory of the weight.

In addition, the screen plate 5 or the delivery roller 3 may be made vertically adjustable, the screen plate 5 may be formed of two upper and lower members, the receiving member 4 may be made longitudinally and vertically adjustable, or the tongue piece 15 may be formed as a separate member. The receiving member 4 is formed with
It may also be attached to.

An actuating body 33 that selectively engages and abuts the stopper portion 32 is provided, and this actuating body 33 is formed by driving a pin into the delivery roller shaft 6.

The engaging portion 31 has the rotating member 7 connected to the driving rotating body 30.
The stopper portion 23 engages with the operating body 33 to transmit power to the delivery roller shaft 6 when the delivery roller shaft 6 is driven by the paper sheet A. This prevents the actuating body 33 from being separated from the engaging portion 31 by more than a certain distance when reversely driven, and prevents the inertial free rotation of the delivery roller shaft 6.

When a predetermined number of coins are inserted into the operating mechanism 26,
The handle 29 is rotatable at a certain angle, and in the embodiment, two ten yen coins are inserted, the handle 29 is rotated 390 degrees, the rotating member 7 is rotated the required amount, and then the handle 29 is rotated 30 degrees. It is configured to rotate back.

A coin detection section 40 is formed between them. Further, a return lever 41 is pivotally supported on the outer surface of one of the frame walls 36, and a return body 42 that engages with the return lever 41 is fixed to the drive shaft 28.

When two coins B enter from the slot 43, they are held by the coin detection section 40 on one side of the operating disk 37, and the second coin B closes the detection recess 44 on the outer periphery of the operating disk 37, causing the coin to be detected. disables engagement with body 38. This allows the drive shaft 28 to rotate via the handle 29, and the drive shaft 28
Rotate 390°. When the drive shaft 28 has rotated 360 degrees, the return body 42 engages with the return lever 41, and the drive shaft 28 is rotated up to 390 degrees against the spring 45. When the drive shaft 28 rotates through 390 degrees, if the next coin is not in the coin detection section 40, the coin detection body 38 engages with the detection recess 44 and prevents the operation disk 37 from rotating. Then handle 2
9, the drive shaft 28 is rotated back by the tensile force of the spring 45 via the return lever 41 and the return body 42, and when the drive shaft 28 returns to 360°, the ratchet pawl 39 is inserted into the ratchet groove 46. This engages and restricts the return rotation of the operating disk 37.

Reference numeral 51 denotes a sell-out mechanism, which is configured to operate when the weight 22 reaches the lowest position.
A detection bar 52 and an actuation bar 53 are pivotally supported on the inner surface of the front wall of the outer case 48 via pins 54 and 55, respectively, so as to be freely rotatable around the front and rear axes. The detection bar 52 has an L-shape when viewed from the front, has a spring 56 connected to one end, a hook 57 at the other end, and an engagement protrusion 58 of the weight 22 on the other end. .

The weight 22 has rollers 60 on the left and right sides for moving up and down along the track 23, and the upper end of a spring 61 for elastically pulling it down is locked, and the front groove 62 of the screen plate 5 is attached to the front part. Engagement protrusion 5 protruding from
8, and has a lifting part 63 at the rear for lifting it up artificially. The lower ends of the spring 61 are secured to the left and right side walls 2a.

The actuating lever 53 has an L-shaped latch 64 at its lower end.
A tensile force is applied in the clockwise direction in the figure, and the hooking portion 64 engages with the hooking portion 57 of the detection bar 52 to prevent it from swinging.

A long groove 66 is formed in the upper part of the actuation bar 53.
A stopper pin 67 is inserted into this long groove 66. This stopper pin 67 is attached to the outer case 48, and together with the long groove 66, the actuating bar 53
The oscillation range is set.

The actuating bar 53 has a beak 68 projecting sideways from the top, and the tip of the beak 68 can be freely inserted into and retracted from the coin slot 69 of the coin selector, so that the actuating bar 53 is moved from the solid line position in Fig. 15. By swinging to the two-dot chain line position, it protrudes into the coin slot 69 and prohibits coin insertion.

Furthermore, a pair of left and right bent tongues 70 protrudes from the upper surface side of the beak 68 .
The tip of the release lever 71 is inserted between them. The release lever 71 is rotatably supported by the side wall 2a,
The tip is bent into an L-shape, and by rotation, the actuating bar 53 can be swung counterclockwise via one of the tongue pieces 70.

The operation of the sold-out mechanism 51 is such that when the remaining amount of stacked paper sheets A becomes zero or one to two sheets, the engagement protrusion 58 of the weight 22 that has reached the lowest position pushes the detection bar 52 against the spring 56. Rotating, the hanging part 57 and the hanging part 64
