[0015] Hereinafter, each embodiment will be described with reference to the drawings. In all the drawings, the same or corresponding configurations are denoted by the same reference numerals, and common descriptions are omitted. In the present disclosure, the drawings are associated with one or more embodiments.

[0016] <First Embodiment> Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 1, a supply system 1A includes a holding portion 2 and a conveying device 3A. The holding portion 2 holds a plurality of sheet-like articles 200 stacked in the vertical direction Dv. Examples of the sheet-like articles 200 include paper sheets, films, and the like. The conveying device 3A sends out the sheet-like articles 200 one by one from the holding portion 2 on which a plurality of sheet-like articles 200 are stacked.

[0017] In the following description, the direction in which the sheet-like article 200 moves when the conveying device 3A feeds it out from the holding unit 2 is referred to as the conveying direction D. In this embodiment, the conveying direction D is aligned with the horizontal direction. The direction in which the sheet-like article 200 is fed out from the holding unit 2 is referred to as the forward direction Df of the conveying direction D, and the opposite direction is referred to as the backward direction Dr of the conveying direction D. Furthermore, the direction intersecting the conveying direction D in the horizontal plane is referred to as the width direction Dw.

[0018] The holding part 2 includes a support base 21, a stopper member 22, and a guide member 23.

[0019] The support base 21 has a support surface 21f that extends along a plane (horizontal plane) that intersects the vertical direction Dv. The support base 21 places multiple sheets of stacked sheet-like articles 200 on the support surface 21f. The support base 21 is provided to be able to move up and down by a lifting mechanism (not shown). The lifting mechanism sequentially raises the support base 21 according to the number of sheet-like articles 200 held on the support base 21, so that the uppermost sheet-like article 200T of the multiple stacked sheet-like articles 200 is positioned at a predetermined height.

[0020] The stopper member 22 is provided above the front end Df of the support base 21 in the transport direction D. The stopper member 22 has a rearward-facing surface 22f that faces rearward Dr in the transport direction D. The stopper member 22 prevents other sheet-like articles 200 below the uppermost sheet-like article 200T from moving forward Df in the transport direction D by abutting against the rearward-facing surface 22f.

[0021] The guide member 23 extends forward Df in the conveying direction D from the upper end of the stopper member 22. The guide member 23 is provided on the underside of the conveying path R of the sheet-like article 200 being fed out from the holding unit 2. The guide member 23 has an upward-facing guide surface 23f. The guide member 23 guides the sheet-like article 200 forward Df in the conveying direction D by aligning the lower surface of the sheet-like article 200 being fed out from the holding unit 2 along the guide surface 23f.

[0022] The conveying device 3A feeds out one sheet at a time from the holding section 2, where multiple sheet-like articles 200 are stacked, selecting the top sheet-like article 200T from among the multiple sheet-like articles 200. As shown in Figures 1 and 2, the conveying device 3A includes a feed roller 31, an upper roller 32, a lower roller 33, and a monitoring mechanism 5A.

[0023] The feed roller 31 is provided above the holding section 2. The feed roller 31 is provided so as to contact the plurality of sheet-like articles 200 held by the holding section 2 from above. The feed roller 31 is provided so as to be rotatable around a rotation axis 31c that extends in the width direction Dw. The feed roller 31 is formed in a cylindrical or disc shape that extends in the width direction Dw. The feed roller 31 is made of, for example, synthetic resin or metal. The feed roller 31 may be provided with a ring member (not shown) on its outer circumferential surface, which is made of, for example, a rubber-based material and increases the frictional force between it and the sheet-like articles 200.

[0024] As shown in Figure 2, the feed roller 31 is rotationally driven in the rotational direction Dc1 around the rotation axis 31c by a drive mechanism such as a motor (not shown). In this embodiment, the feed roller 31 applies a frictional force F0 directed forward Df in the conveying direction D to the uppermost sheet-like article 200T so as to feed the uppermost sheet-like article 200T forward Df in the conveying direction D. The feed roller 31 may also be biased downward by a biasing member such as a spring (not shown) relative to the plurality of sheet-like articles 200 held in the holding part 2.

[0025] The upper roller 32 and the lower roller 33 are positioned in a direction Df forward in the conveying direction D relative to the holding section 2. As shown in Figures 1 to 3, the upper roller 32 is located above the transport path R of the uppermost sheet-like article 200T that is fed out by the feed roller 31. The upper roller 32 is rotatably mounted around a rotation axis 32c parallel to the rotation axis 31c. The upper roller 32 is formed in a cylindrical or disc shape extending in the width direction Dw. In this embodiment, the upper roller 32 is formed in a disc shape and multiple rollers (for example, two) are provided on the rotation axis 32c at intervals in the width direction Dw.

[0026] The upper roller 32 is made of, for example, synthetic resin, metal, etc. The upper roller 32 may have a ring member (not shown) on its outer circumferential surface, which is made of, for example, a rubber-based material to increase the frictional force between it and the sheet-like article 200. The upper roller 32 may be formed from the same material as the feed roller 31, or from a different material than the feed roller 31.

[0027] As shown in Figure 2, the upper roller 32 is rotationally driven in a rotational direction Dd1 around the rotation axis 32c by a drive mechanism such as a motor (not shown). This rotational direction Dd1 is the same as the rotational direction Dc1 of the feed roller 31. In this embodiment, the upper roller 32 applies a first frictional force F1 directed forward Df in the conveying direction D to the uppermost sheet-like article 200T so that the uppermost sheet-like article 200T is fed forward Df in the conveying direction D. The upper roller 32 may also be biased downward relative to the uppermost sheet-like article 200T by a biasing member such as a spring (not shown).

[0028] As shown in Figures 1 to 3, the lower roller 33 is located below the transport path R of the uppermost sheet-like article 200T that is fed out by the feed roller 31. The lower roller 33 is positioned opposite the upper roller 32 in the vertical direction Dv. The lower roller 33 is positioned overlapping the upper roller 32 in the transport direction D. The lower roller 33 is rotatably mounted around a rotation axis 33c parallel to the rotation axes 31c and 32c. The lower roller 33 is formed in a cylindrical or disc shape extending in the width direction Dw. In this embodiment, the lower roller 33 is formed in a disc shape and multiple (e.g., two) are provided on the rotation axis 33c at intervals in the width direction Dw. In this embodiment, the number of lower rollers 33 and the spacing between them in the width direction Dw are the same as those of the upper rollers 32. Each lower roller 33 is positioned in the same location as the upper roller 32 in the width direction Dw.

[0029] The lower roller 33 is made of, for example, synthetic resin or metal. The lower roller 33 may have a ring member (not shown) on its outer circumferential surface, which is made of, for example, a rubber-based material to increase the frictional force between it and the sheet-like article 200. The lower roller 33 may be formed from the same material as the feed roller 31 and the upper roller 32, or from a different material than the feed roller 31 and the upper roller 32.

[0030] As shown in Figure 2, the lower roller 33 is rotationally driven in a rotational direction De1 around the rotation axis 33c by a drive mechanism such as a motor (not shown). The rotational direction De1 of the lower roller 33 is opposite to the rotational directions Dc1 and Dd1 of the feed roller 31 and upper roller 32. In this embodiment, the lower roller 33 applies a second frictional force F2 to the lower surface of the uppermost sheet-like article 200T toward the rear Dr in the conveying direction D. The lower roller 33 may also be biased upward relative to the uppermost sheet-like article 200T by a biasing member such as a spring (not shown).

[0031] As shown in Figures 1 and 2, the monitoring mechanism 5A comprises a detection unit 50, a retractable member 55A, and a control unit 6. The detection unit 50 detects the state of the uppermost sheet-like article 200T among the multiple sheet-like articles 200 that have been fed out from the holding unit 2. In this embodiment, the detection unit 50 includes a multiple feed detection sensor (second sensor) 51, a jam detection sensor (third sensor) 52, and a scratch detection sensor (first sensor) 53.

[0032] The jam detection sensor 52 is provided, for example, at the rear Dr in the transport direction D relative to the upper roller 32 and the lower roller 33, and at the front Df in the transport direction D relative to the feed roller 31. The multiple feed detection sensor 51 and the scratch detection sensor 53 are provided, for example, at the front Df in the transport direction D relative to the upper roller 32 and the lower roller 33.

[0033] The multiple feed detection sensor 51 can detect a multiple feed state in which multiple sheet-like articles 200 are fed out from the holding unit 2 by the feed roller 31, not just the top sheet-like article 200T. The multiple feed detection sensor 51 can detect the multiple feed state by detecting the thickness of the sheet-like articles 200 fed out from the holding unit 2 by the feed roller 31 and their length in the transport direction D.

[0034] The jam detection sensor 52 can detect the jammed state of the uppermost sheet-like article 200T that has been fed out from the holding section 2 by the feed roller 31. The scratch detection sensor 53 can detect the occurrence of scratches on the leading edge 200s of the uppermost sheet-like article 200T, which is fed out from the upper roller 32 and the lower roller 33. The scratch detection sensor 53 is a line sensor that extends in the width direction Dw and scans the leading edge 200s of the uppermost sheet-like article 200T to detect the presence or absence of scratches.

[0035] As shown in Figures 2 and 3, the reciprocating member 55A is capable of pressing the uppermost sheet-like article 200T, which is fed out from the holding unit 2, upward. The reciprocating member 55A is provided below the transport path R of the uppermost sheet-like article 200T fed out from the holding unit 2. In this embodiment, the reciprocating member 55A is provided in a position that overlaps with the upper roller 32 and the lower roller 33 in the transport direction D. In the width direction Dw, the reciprocating member 55A is positioned between multiple adjacent sets of upper rollers 32 and lower rollers 33.

[0036] The reciprocating member 55A is made movable in the vertical direction Dv by a support member (not shown). The tip (upper end) 55s of the reciprocating member 55A in this embodiment is formed in a curved shape that is convex upward when viewed from the width direction Dw. Furthermore, the tip (upper end) 55s of the reciprocating member 55A in this embodiment is restricted in a curved shape that is convex upward when viewed from the conveying direction D. By forming the tip 55s of the reciprocating member 55A in a curved shape in this way, the frictional force generated between the reciprocating member 55A and the uppermost sheet-like article 200T is reduced. This configuration effectively exerts the first frictional force F1 and the second frictional force F2 generated between the upper roller 32 and the lower roller 33 and the uppermost sheet-like article 200T.

[0037] The reciprocating member 55A is driven to move forward and backward in the vertical direction Dv by a predetermined stroke by a drive mechanism 56. In this embodiment, the drive mechanism 56 includes, for example, an eccentric cam 57 and a motor 58 that rotationally drives the eccentric cam 57. The eccentric cam 57 is rotationally driven around a horizontal axis by the motor 58, thereby driving the reciprocating member 55A to move forward and backward in the vertical direction Dv by a predetermined stroke.

[0038] The reciprocating member 55A, which is driven to move back and forth in the vertical direction Dv by the drive mechanism 56, has its tip 55s positioned a predetermined distance above the lower end of the upper roller 32 in the vertical direction Dv at the upper end position of a predetermined stroke. The reciprocating member 55A has its tip 55s positioned a predetermined distance below the upper end of the lower roller 33 at the lower end position of a predetermined stroke. The drive mechanism 56 may be, for example, a cylinder actuator, as long as it can drive the reciprocating member 55A to move back and forth in the vertical direction Dv.

[0039] (Configuration of the control unit) The control unit 6 controls the retractable member 55A based on the state of the uppermost sheet-like article 200T that has been fed out from the holding unit 2, as detected by the detection unit 50. As shown in Figure 2, the control unit 6 comprises a Central Processing Unit (hereinafter referred to as "CPU") 310 and a memory 320.

[0040] The CPU 310 functionally includes an acquisition unit 311 and a forward / backward control unit 312. In other words, the CPU 310 performs its functions as an acquisition unit 311 and an advance / reverse control unit 312 by operating according to a predetermined program. The memory 320 stores various data acquired by the control unit 6.

[0041] The acquisition unit 311 acquires the state of the uppermost sheet-like article 200T detected by the detection unit 50. When the acquisition unit 311 acquires a signal from at least one of the multiple feed detection sensor 51, jam detection sensor 52, and scratch detection sensor 53 indicating the detection of a multiple feed state, a jam state, or the occurrence of a scratch, it notifies the forward / backward control unit 312 that it has given a signal. If the acquisition unit 311 receives a signal from the multiple feed detection sensor 51 indicating that multiple feeds have occurred in the uppermost sheet-like article 200T, it notifies the reciprocating control unit 312 that multiple feeds have occurred. If the acquisition unit 311 receives a signal from the jam detection sensor 52 indicating that a jam has occurred in the uppermost sheet-like article 200T, it notifies the reciprocating control unit 312 that a jam has occurred. If the acquisition unit 311 receives a signal from the scratch detection sensor 53 indicating that a scratch has occurred in the leading edge 200s of the uppermost sheet-like article 200T, it notifies the reciprocating control unit 312 that a scratch has occurred.

[0042] The reciprocating control unit 312 moves the reciprocating member 55A up and down so that it can switch between the following first state A1 and second state A2 based on the state of the uppermost sheet-like article 200T. Based on the notification from the acquisition unit 311, if at least one of the following occurs in the uppermost sheet-like article 200T—multiple feed condition, jam condition, or damage—the reciprocating control unit 312 moves the reciprocating member 55A up and down to switch to the first state A1 or the second state A2. In this embodiment, the reciprocating control unit 312 moves the reciprocating member 55A up and down to switch to the first state A1 or the second state A2 if the occurrence rate of each of the multiple feed condition, jam condition, and damage in the uppermost sheet-like article 200T exceeds a preset rate. Furthermore, the forward / backward control unit 312 may move the forward / backward member 55A up and down to switch to the first state A1 or the second state A2 if a multiple feed condition, jam condition, or damage occurs in the uppermost sheet-like article 200T more than a preset number of times (including once).

[0043] As shown in Figures 4 and 5, in the first state A1, the reciprocating member 55A is raised to the upper end position of a predetermined stroke. In the first state A1, by raising the reciprocating member 55A to the upper end position, the tip portion 55s is positioned a predetermined distance above the lower end of the upper roller 32 in the vertical direction Dv. As a result, the uppermost sheet-like article 200T fed out from the holding unit 2 is pushed upward from below by the reciprocating member 55A, and the tip portion 200s of the uppermost sheet-like article 200T at the front Df in the conveying direction D contacts the upper roller 32.

[0044] As shown in Figure 6, in the second state A2, the reciprocating member 55A is lowered to the lower end position of a predetermined stroke. In the second state A2, by lowering the reciprocating member 55A to the lower end position, the tip portion 55s is positioned a predetermined distance below the upper end of the lower roller 33 in the vertical direction Dv. As a result, the uppermost sheet-like article 200T sent out from the holding unit 2 does not come into contact with the reciprocating member 55A, and its tip portion 200s tends to hang downward due to its own weight. Consequently, the tip portion 200s of the uppermost sheet-like article 200T at the front Df in the conveying direction D is more likely to come into contact with the lower roller 33.

[0045] In the reciprocating control unit 312, if the acquisition unit 311 has not received a detection signal from at least one of the multiple feed detection sensor 51, the jam detection sensor 52, and the scratch detection sensor 53, the reciprocating member 55A is positioned at a predetermined reference position, as shown in Figures 2 and 3. In other words, if the uppermost sheet-like article 200T fed out from the holding unit 2 is not in a multiple feed state, jam state, or scratch state, the reciprocating member 55A is positioned at a predetermined reference position. Here, the reference position of the reciprocating member 55A is set such that, for example, the tip 55s of the reciprocating member 55A is slightly higher than the upper end of the lower roller 33. The reference position of the reciprocating member 55A may also be set such that, for example, the tip 55s of the reciprocating member 55A is at the same height as the upper end of the lower roller 33. The reference position of the retractable member 55A is not limited to this; for example, the tip portion 55s of the retractable member 55A may be set to be located a predetermined distance below the upper end of the lower roller 33.

[0046] When the reciprocating control unit 312 detects a multiple feed state using the multiple feed detection sensor 51, it switches to a second state A2, as shown in Figure 6, by lowering the reciprocating member 55A by a predetermined distance, so that the leading edge 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D contacts the lower roller 33 before the upper roller 32. Here, the first frictional force F1 is the frictional force between the upper roller 32 and the uppermost sheet-like article 200T. The second frictional force F2 is the frictional force between the lower roller 33 and the other sheet-like article 200 that is overlapping the uppermost sheet-like article 200T. The inter-sheet frictional force Fs is the frictional force between the uppermost sheet-like article 200T and the other sheet-like article 200 that is overlapping it. In the multiple feed state, the first friction force F1, the second friction force F2, and the inter-sheet friction force Fs have the following relationship (1). F1 > F2, and Fs > F2...(1)

[0047] In this state of multiple feeds, the reciprocating member 55A is lowered by a predetermined distance, causing the front end 200s of the uppermost sheet-like article 200T at the forward Df in the conveying direction D to contact the lower roller 33 before the upper roller 32. As a result, the second frictional force F2 between the lower roller 33 and the other sheet-like articles 200 overlapping the lower side of the uppermost sheet-like article 200T increases, and the relationship in (1) above changes to the relationship in (2) below. F1 > F2, and F2 > Fs ... (2) The second frictional force F2 applied from the lower roller 33 to the other sheet-like articles 200 overlapping the uppermost sheet-like article 200T increases, thereby preventing the other sheet-like articles 200 from being fed forward Df in the conveying direction D. This suppresses the occurrence of multiple feeds.

[0048] When the jam detection sensor 52 detects a jam, the forward / backward control unit 312 raises the forward / backward member 55A by a predetermined dimension, as shown in Figures 4 and 5, to bring the leading edge 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D to contact the upper roller 32 before the lower roller 33, thus entering a first state A1. Jamming of the uppermost sheet-like item 200T often occurs when the leading edge 200s of the uppermost sheet-like item 200T, in the forward direction Df of the conveying direction D, droops down and abuts against the lower roller 33. When a jamming condition is detected, the leading edge 200s of the uppermost sheet-like item 200T is brought into contact with the upper roller 32 before the lower roller 33, thereby suppressing the occurrence of jamming.

[0049] In the forward / backward control unit 312, if the scratch detection sensor 53 detects the occurrence of a scratch, the forward / backward member 55A is raised by a predetermined dimension, and the leading edge 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D contacts the upper roller 32 before the lower roller 33, resulting in a first state A1. Damage to the leading edge 200s of the uppermost sheet-like article 200T often occurs when the leading edge 200s at the front Df in the conveying direction D of the uppermost sheet-like article 200T droops down and strikes the lower roller 33. When damage is detected, the occurrence of damage can be suppressed by making the leading edge 200s of the uppermost sheet-like article 200T contact the upper roller 32 before the lower roller 33.

[0050] (Control method for conveying equipment) As shown in Figure 7, the control method for the conveying device includes the steps of: S11 to acquire the state of the uppermost sheet-like article; S12 to determine whether or not there is an abnormality in the state of the sheet-like article; and S13 to switch to either the first state or the second state.

[0051] In step S11, which involves acquiring the state of the topmost sheet-like article, the acquisition unit 311 of the control unit 6 acquires the state of the topmost sheet-like article 200T detected by the detection unit 50 at predetermined time intervals. In step S11, if multiple feeds occur in the topmost sheet-like article 200T, a signal indicating that multiple feeds have occurred is acquired from the multiple feed detection sensor 51. In step S11, if a jam occurs in the topmost sheet-like article 200T, a signal indicating that a jam has occurred is acquired from the jam detection sensor 52. In step S11, if a scratch occurs in the topmost sheet-like article 200T, a signal indicating that a scratch has occurred is acquired from the scratch detection sensor 53.

[0052] In step S12, which determines whether or not there is an abnormality in the condition of the sheet-like article, in step S11, the forward / backward control unit 312 determines whether or not it has acquired a signal from at least one of the multiple feed detection sensor 51, jam detection sensor 52, and scratch detection sensor 53 indicating the detection of a multiple feed state, a jam state, and the occurrence of a scratch. In step S12, if a signal indicating the detection of a multiple feed state, a jam state, and the occurrence of a scratch has been acquired from at least one of the multiple feed detection sensor 51, jam detection sensor 52, and scratch detection sensor 53, the forward / backward control unit 312 calculates the occurrence rate of the multiple feed state, jam state, and scratch. In step S12, if the calculated occurrence rates of multiple feeds, jams, and scratches are below a preset standard (step S12: No), the process ends, and after a predetermined time has elapsed, the process from step S11 is repeated. In step S12, if the calculated occurrence rates of multiple feeds, jams, and scratches are above a preset standard (step S12: Yes), the process proceeds to step S13.

[0053] In step S13, which switches between the first and second states, if the multiple feed detection sensor 51 detects a multiple feed state, the reciprocating control unit 312 lowers the reciprocating member 55A by a predetermined distance, as shown in Figure 6, and switches to the second state A2, in which the leading edge 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D contacts the lower roller 33 before the upper roller 32. Furthermore, when the jam detection sensor 52 detects a jam, the forward / backward control unit 312 raises the forward / backward member 55A by a predetermined dimension, as shown in Figures 4 and 5, to bring the leading edge 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D to contact the upper roller 32 before the lower roller 33, thus creating a first state A1. When the scratch detection sensor 53 detects the occurrence of a scratch, the retraction control unit 312 raises the retraction member 55A by a predetermined dimension, bringing the leading edge 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D to contact the upper roller 32 before the lower roller 33, thus entering a first state A1.

[0054] In the supply system 1A of this embodiment, based on the state of the uppermost sheet-like article 200T, the system can switch between a first state A1, in which the leading edge Df of the uppermost sheet-like article 200T in the transport direction D is brought into contact with the upper roller 32 located above the transport path R of the uppermost sheet-like article 200T, and a second state A2, in which the reciprocating member 55A is lowered based on the state of the uppermost sheet-like article 200T, bringing the leading edge of the uppermost sheet-like article 200T into contact with the lower roller 33 located below the transport path R. Therefore, based on the state of the uppermost sheet-like article 200T, the relationship of frictional force and contact state between the uppermost sheet-like article 200T and the upper roller 32 and the lower roller 33 can be adjusted. Consequently, errors in the supply of the sheet-like article 200T can be more effectively suppressed.

[0055] (Modification of the first embodiment) As shown in Figure 8, in the supply system 1B of this disclosure, the monitoring mechanism 5B of the transport device 3B comprises a detection unit 50, a retractable member 55B, and a control unit 6.

[0056] In this embodiment, the reciprocating member 55B is provided below the transport path R of the uppermost sheet-like article 200T being fed out from the holding unit 2. In this embodiment, the reciprocating member 55B is provided rearward Dr in the transport direction D relative to the upper roller 32 and the lower roller 33. The reciprocating member 55B is provided forward Df in the transport direction D relative to the feed roller 31.

[0057] Even in a supply system 1B equipped with a monitoring mechanism 5B with this configuration, it is easier to more effectively suppress supply errors of the sheet-like articles 200T being dispensed.

[0058] <Second Embodiment> An embodiment of this disclosure will be described below with reference to the figures. As shown in Figure 9, the monitoring mechanism 5C comprises a detection unit 50, a retractable member 55C, and a control unit 6.

[0059] The detection unit 50 detects the state of the uppermost sheet-like article 200T among the multiple sheet-like articles 200 that are fed out from the holding unit 2 in which multiple sheet-like articles 200 are stacked.

[0060] The reciprocating member 55C is provided on the lower side of the transport path R. The reciprocating member 55C is capable of moving back and forth in the vertical direction Dv. The reciprocating member 55C is capable of pressing the uppermost sheet-like article 200T that has been fed out upwards.

[0061] The control unit 6 is switchable between a first state A1 and a second state A2 based on the state of the uppermost sheet-like article 200T. In the first state A1, the retractable member 55C is raised to bring the front end 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D into contact with the upper roller 32 located above the transport path R of the uppermost sheet-like article 200T. In the second state A2, the retractable member 55C is lowered to bring the front end 200s of the uppermost sheet-like article 200T into contact with the lower roller 33 located below the transport path R.

[0062] The monitoring mechanism 5C of this embodiment can be switched between a first state A1 and a second state A2 based on the state of the uppermost sheet-like article 200T. Therefore, the relationship of frictional force and contact state between the uppermost sheet-like article 200T and the upper roller 32 and lower roller 33 can be adjusted based on the state of the uppermost sheet-like article 200T. Consequently, errors in the supply of the unfed sheet-like article 200T can be more effectively suppressed.

[0063] <Third Embodiment> An embodiment of this disclosure will be described below with reference to the figures. As shown in Figure 10, the transport device 3D includes a feed roller 31, an upper roller 32, a lower roller 33, a detection unit 50, a reciprocating member 55D, and a control unit 6.

[0064] The feed roller 31 feeds out the uppermost sheet-like article 200T from the holding section 2, where multiple sheet-like articles 200 are stacked. The upper roller 32 is positioned above the transport path R of the uppermost sheet-like article 200T that has been fed out. The upper roller 32 applies a first frictional force F1 to the upper surface of the uppermost sheet-like article 200T in the forward direction Df of the transport direction D of the uppermost sheet-like article 200T. The lower roller 33 is located below the transport path R of the uppermost sheet-like article 200T that is being fed out. The lower roller 33 applies a second frictional force F2 to the underside of the uppermost sheet-like article 200T in the direction of rear Dr in the transport direction D.

[0065] The detection unit 50 detects the state of the uppermost sheet-like article 200T among the multiple sheet-like articles 200 that are fed out from the holding unit 2 in which multiple sheet-like articles 200 are stacked.

[0066] The reciprocating member 55D is provided on the lower side of the transport path R. The reciprocating member 55D is capable of moving back and forth in the vertical direction Dv. The reciprocating member 55D is capable of pressing the uppermost sheet-like article 200T that has been fed out upwards.

[0067] The control unit 6 is switchable between a first state A1 and a second state A2 based on the state of the uppermost sheet-like article 200T. In the first state A1, the retractable member 55D is raised to bring the front end 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D into contact with the upper roller 32 located above the transport path R of the uppermost sheet-like article 200T. In the second state A2, the retractable member 55D is lowered to bring the front end 200s of the uppermost sheet-like article 200T into contact with the lower roller 33 located below the transport path R.

[0068] The conveying device 3D of this embodiment can switch between a first state A1 and a second state A2 based on the state of the uppermost sheet-like article 200T. Therefore, the relationship of frictional force and contact state between the uppermost sheet-like article 200T and the upper roller 32 and lower roller 33 can be adjusted based on the state of the uppermost sheet-like article 200T. Consequently, errors in supplying the sheet-like article 200T can be more effectively suppressed.

[0069] <Fourth Embodiment> An embodiment of this disclosure will be described below with reference to the figures. As shown in Figure 11, the supply system 1E comprises a holding unit 2, a feeding roller 31, an upper roller 32, a lower roller 33, a detection unit 50, a reciprocating member 55E, and a control unit 6. The holding section 2 is formed by stacking multiple sheet-like articles 200 on top of each other.

[0070] The feed roller 31 feeds out the uppermost sheet-like article 200T from the holding section 2, where multiple sheet-like articles 200 are stacked. The upper roller 32 is positioned above the transport path R of the uppermost sheet-like article 200T that has been fed out. The upper roller 32 applies a first frictional force F1 to the upper surface of the uppermost sheet-like article 200T in the forward direction Df of the transport direction D of the uppermost sheet-like article 200T. The lower roller 33 is located below the transport path R of the uppermost sheet-like article 200T that is being fed out. The lower roller 33 applies a second frictional force F2 to the underside of the uppermost sheet-like article 200T in the direction of rear Dr in the transport direction D.

[0071] The detection unit 50 detects the state of the uppermost sheet-like article 200T among the multiple sheet-like articles 200 that are fed out from the holding unit 2 in which multiple sheet-like articles 200 are stacked.

[0072] The reciprocating member 55E is provided on the lower side of the transport path R. The reciprocating member 55E is capable of moving back and forth in the vertical direction Dv. The reciprocating member 55E is capable of pressing the uppermost sheet-like article 200T that has been fed out upwards.

[0073] The control unit 6 is switchable between a first state A1 and a second state A2 based on the state of the uppermost sheet-like article 200T. In the first state A1, the retractable member 55E is raised to bring the front end 200s of the uppermost sheet-like article 200T at the front Df in the transport direction D into contact with the upper roller 32 located above the transport path R of the uppermost sheet-like article 200T. In the second state A2, the retractable member 55E is lowered to bring the front end 200s of the uppermost sheet-like article 200T into contact with the lower roller 33 located below the transport path R.

[0074] The supply system 1E of this embodiment is switchable between a first state A1 and a second state A2 based on the state of the uppermost sheet-like article 200T. Therefore, the relationship of frictional force and contact state between the uppermost sheet-like article 200T and the upper roller 32 and lower roller 33 can be adjusted based on the state of the uppermost sheet-like article 200T. Consequently, errors in the supply of the sheet-like article 200T can be more effectively suppressed.

[0075] <Fifth Embodiment> An embodiment of this disclosure will be described below with reference to the figures. As shown in Figure 12, the control device 6F controls the transport device 3F. The conveying device 3F comprises a feed roller 31, an upper roller 32, a lower roller 33, a detection unit 50, a reciprocating member 55F, and a control device 6F.

[0076] The feed roller 31 feeds out the uppermost sheet-like article 200T from the holding section 2, where multiple sheet-like articles 200 are stacked. The upper roller 32 is positioned above the transport path R of the uppermost sheet-like article 200T that has been fed out. The upper roller 32 applies a first frictional force F1 to the upper surface of the uppermost sheet-like article 200T in the forward direction Df of the transport direction D of the uppermost sheet-like article 200T. The lower roller 33 is located below the transport path R of the uppermost sheet-like article 200T that is being fed out. The lower roller 33 applies a second frictional force F2 to the underside of the uppermost sheet-like article 200T in the direction of rear Dr in the transport direction D.

[0077] The detection unit 50 detects the state of the uppermost sheet-like article 200T among the multiple sheet-like articles 200 that are fed out from the holding unit 2 in which multiple sheet-like articles 200 are stacked.

[0078] The reciprocating member 55F is provided on the lower side of the transport path R. The reciprocating member 55F is capable of moving back and forth in the vertical direction Dv. The reciprocating member 55F is capable of pressing the uppermost sheet-like article 200T that has been fed out upwards.

[0079] The control device 6F includes an acquisition unit 311F and a forward / backward control unit 312F. The acquisition unit 311F acquires the state of the uppermost sheet-like item 200T detected by the detection unit 50.

[0080] The forward / backward control unit 312F is switchable between a first state A1 and a second state A2 based on the state of the uppermost sheet-like article 200T. In the first state A1, the forward / backward member 55F is raised to bring the front end 200s of the uppermost sheet-like article 200T, in the forward direction Df of the transport direction D, into contact with the upper roller 32. In the second state A2, the forward / backward member 55F is lowered to bring the front end 200s of the uppermost sheet-like article 200T into contact with the lower roller 33.

[0081] The control device 6F of this embodiment can switch between a first state A1 and a second state A2 based on the state of the uppermost sheet-like article 200T. Therefore, the relationship of frictional force and contact state between the uppermost sheet-like article 200T and the upper roller 32 and lower roller 33 can be adjusted based on the state of the uppermost sheet-like article 200T. Consequently, errors in the supply of the unfed sheet-like article 200T can be more effectively suppressed.

[0082] <Sixth Embodiment> An embodiment of this disclosure will be described below with reference to the figures. As shown in Figure 13, the control method for the conveying device includes step S71 of acquiring the state of the top sheet-like article, and step S72 of switching to either the first state or the second state.

[0083] The conveying device comprises a feed roller, an upper roller, a lower roller, a detection unit, and a retractable member.

[0084] The feed roller feeds out the top sheet-like material from a holding section where multiple sheet-like materials are stacked on top of each other. The upper roller is positioned above the transport path of the uppermost sheet-like article that is being fed out. The upper roller applies a first frictional force to the upper surface of the uppermost sheet-like article, directed forward in the transport direction of the uppermost sheet-like article. The lower roller is located beneath the conveying path of the uppermost sheet-like article that is being fed out. The lower roller applies a second frictional force to the underside of the uppermost sheet-like article, directed towards the rear in the conveying direction.

[0085] The detection unit detects the state of the topmost sheet-like material among multiple sheet-like materials that are fed out from a holding unit where multiple sheet-like materials are stacked on top of each other.

[0086] The reciprocating member is located on the underside of the transport path. The reciprocating member is capable of moving back and forth in the vertical direction. The reciprocating member can press the uppermost sheet-like article being fed out upwards.

[0087] In step S71, which involves acquiring the state of the topmost sheet-like item, the state of the topmost sheet-like item detected by the detection unit is acquired.

[0088] In step S72, which switches between the first state and the second state, the switch is made based on the state of the top sheet-like article. In the first state, the reciprocating member is raised so that the front end of the uppermost sheet-like article in the direction of transport contacts the upper roller. In the second state, the reciprocating member is lowered so that the front end of the uppermost sheet-like article contacts the lower roller.

[0089] The control method of the control device in this embodiment is switchable between a first state and a second state based on the state of the uppermost sheet-like article. Therefore, the relationship of frictional force and contact state between the uppermost sheet-like article and the upper and lower rollers can be adjusted based on the state of the uppermost sheet-like article. Consequently, errors in the supply of the dispensed sheet-like article can be more effectively suppressed.

[0090] The programs for the control unit 6 and the control device 6F described above may be for the purpose of implementing some of the functions described above. Furthermore, they may be programs that can implement the functions described above in combination with programs already recorded in the computer system, so-called differential files (differential programs).
