Description

  The present invention relates to, for example, a sheet-like material guide device that switches sheets to be loaded on a paper stacking device in a sheet-fed rotary printing press or to pass paper without being stacked on the paper stacking device.

In the conventional sheet-like material guide device, each paper stacking device is provided with a front pad, and is advanced above and above the paper stacking device provided on the upstream side in the paper transport direction. Then, a paper guide for guiding the paper to the paper stacking device on the downstream side in the paper transport direction is provided, and when the paper guide is retracted, the paper is placed in front of the paper stacking device provided on the upstream side in the paper transport direction. The paper is brought into contact with the paper stacking apparatus (see, for example, Patent Document 1). Also, in order to reliably load the paper stacking device on the upstream side in the paper transport direction, the height of the front pad is increased, and this front pad is loaded on the paper stacking device on the downstream side in the paper transport direction as a structure that can be raised and lowered. When doing, there is also a thing which makes the front seat fall down (for example, refer patent document 2). In addition, in order to securely load paper on each paper stacking device, not only can the front contact be raised and lowered, but also an air nozzle that changes the air blowing angle in conjunction with the front and rear rise and fall is provided. When loading paper on the upstream paper stacking device, air is blown from the air nozzle to the top surface of the stacking paper of the paper stacking device, generating negative pressure between the top surface of the stacking paper and the transported paper, When loading paper on a paper stacking device on the downstream side in the paper transport direction, there is a paper that floats up by blowing air from below the paper (see, for example, Patent Document 3). In addition, the applicant could not find prior art documents closely related to the present invention by the time of filing other than the prior art documents specified by the prior art document information described in this specification. .
Japanese Patent Publication No. 6-40185 (page 3, right column, lines 1 to 11, Fig. 1) Utility Model Registration No. 2588807 (paragraphs “0020” and “0021”, FIG. 4) Japanese Patent No. 2517276 (page 3, left column, line 44 to right column, line 20, FIG. 1)

  Of the conventional sheet-like material guide devices described above, the first device described above has a structure in which the front application is always upright, so that paper is loaded on the paper stacking device on the downstream side in the paper transport direction. Considering what to do, the height of the advancement is naturally limited. For this reason, thick paper having a relatively heavy weight has a problem of overcoming the front seat due to the large inertia of the paper. In addition, in the apparatus described secondly, the front cover can be raised and lowered so that the paper does not get over the front cover, but other than a drive source for moving the paper guide forward and backward. In addition, since a drive source for making the front and rear support freely is required, there is a problem that not only the manufacturing cost increases but also the structure becomes complicated. Further, in the third apparatus, there is a problem that it is necessary to adjust the amount of blown out air according to the type of paper, that is, the thickness, size, weight, and the like, which places a burden on the operator.

  The present invention has been made in view of the above-described conventional problems. The object of the present invention is to load a sheet-like object on a predetermined stacking device without overcoming the front cover and use a single drive source. The purpose is to simplify the structure, reduce the manufacturing cost, and reduce the burden on the operator.

  In order to achieve this object, the invention according to claim 1 includes a sheet-like material conveying unit that holds and conveys a sheet-like material, and a stacking device that loads the sheet-like material conveyed by the sheet-like material conveying unit. A first state in which the sheet-like material held by the sheet-like material conveying means is released and discharged to the stacking device; and the sheet-like material held by the sheet-like material conveying means passes through the stacking device. Switching means for switching to a second state to be conveyed downstream in the sheet conveyance direction, a first regulation means for regulating the sheet-like material released in the first state, and a drive means The sheet-like material guide movable between the guide position for guiding the sheet-like material that has advanced and passed through the upper side of the stacking device in the second state and the retreat position retracted from the guide position. Means and In the sheet-like material guide apparatus provided, when the second state is switched to the first state, the driving means is positioned at a restriction position that restricts the sheet-like material on the upper side of the first restriction means, And a second restricting means that is positioned at a retracted position where the driving means does not restrict the sheet-like material when the first state is switched to the second state.

  The invention according to claim 2 is the invention according to claim 1, wherein the second restricting means is moved by the movement of the sheet-like object guiding means.

  According to a third aspect of the present invention, in the first aspect of the invention, the second restricting means is advanced to a position higher than the upper surface of the sheet-like material guiding means when in the first state, In the state 2, the sheet-like object guiding means is retracted to a lower position below the upper surface.

  According to a fourth aspect of the present invention, in the first aspect of the invention, the second restricting means is rotatably supported and an engaged portion is provided in the second restricting means, and the sheet-like material guiding means is provided. The sheet-like material guiding means is provided with an engaging portion that engages with the engaged portion by the movement to the retracted position and rotates the second restricting means to move to the restricting position.

  The invention according to claim 5 is the invention according to claim 1, wherein the second restricting means is rotatably supported by the sheet-like object guide means, and the sheet-like object guide means is moved to the retracted position. Is provided with an engaging member that engages with the second restricting means and rotates the second restricting means to move to the restricting position.

  According to the first aspect of the invention, the second restricting means for restricting the conveyance of the sheet-like material is provided on the upper side of the first restricting means, thereby restricting the sheet-like material from overcoming the first restricting means. Therefore, the sheet-like material can be reliably discharged to a predetermined stacking device. Further, since the sheet-like material guiding means and the second restricting means are driven by one driving means, the structure can be simplified and the manufacturing cost can be reduced.

  According to the invention of claim 2, since the sheet-like material guiding means and the second restricting means are interlocked with each other, it is not necessary for the worker to adjust the operation timing of the second restricting means. Can be reduced. Further, since the guide means and the second restricting means are interlocked, the second restricting means can be positioned at the restricting position in a timely manner when the switching means switches from the second state to the first state. Therefore, the sheet-like object can be reliably discharged to the stacking device.

  According to the invention of claim 3, in the first state, the second regulating means is advanced to a position higher than the upper surface of the sheet-like material guiding means, so that the sheet-like material is the first regulation. Since it is possible to reliably control overcoming the means, the sheet-like object can be reliably discharged by a predetermined stacking device.

  According to the inventions according to claims 4 and 5, the second restricting means is moved to the restricting position in accordance with the movement of the sheet guide means between the existing sheet guide means and the second restricting means. It is only necessary to provide the engaging means, and the number of parts can be minimized and the structure can be simplified.

Paper chains 4 and 4 are stretched. Between the pair of left and right paper discharge chains 4 and 4, a paper discharge claw 5 that transports paper as a sheet-like material is supported at a certain interval in the running direction of the paper discharge chain 4.

  Reference numeral 6 denotes a first pile as a stacking device located on the upstream side in the paper conveyance direction, and reference numeral 7 denotes a second pile located on the downstream side in the paper conveyance direction. Paper releasing mechanisms 8 and 9 are provided above the first and second piles 6 and 7, respectively. The paper releasing mechanism 8 provided above the first pile 6 includes switching means described later. 10 is provided. By actuating this switching means 10, the paper held by the traveling paper discharge claw 5 is released and dropped onto the first pile 6, or the paper passes through the paper discharge claw 5 while holding the paper. The choice of whether to do is made.

  The paper release mechanism 9 provided above the second pile 7 is provided with a fixed cam. The paper discharge claw 5 that has passed over the first pile 6 contacts the fixed cam, and the paper is discharged by the cam action. When paper is held on the claw 5, the paper is dropped and loaded on the second pile 7. Reference numeral 11 denotes a front pad as a first restricting means provided on the downstream side in the paper conveying direction above the first pile 6, and as shown in FIG. The paper is supported by the shaft 12 standing upright, and the front end of the paper that is released from the grip of the paper discharge claw 5 by the paper release mechanism 8 comes into contact with it and falls onto the first pile 6. Reference numeral 13 denotes a front pad provided on the downstream side in the paper transport direction above the second pile 7, and the front end of the paper P that is released from the grip of the paper discharge claw 5 by the paper release mechanism 9 and comes into contact with the first pile 7 contacts the first pile 7. 2 falls on pile 7.

  Next, the switching means 10 provided in the paper releasing mechanism 8 will be described with reference to FIG. Since this paper release mechanism 8 is disclosed in Utility Model Registration No. 2576854, its outline will be described here. Reference numeral 15 denotes a base plate fixed to the paper discharge frame 2. On the base plate 15, there is provided a screw rod 16 which is rotatable with a motor as a drive source and whose movement in the axial direction is restricted. Reference numeral 17 denotes a moving plate, which is supported so as to be movable in the direction of arrows AB with respect to the base plate 15 via a guide member 18, and the threaded portion of the pin 19 implanted in the moving plate 17 is a screw rod. 16 is screwed. Therefore, when the screw rod 16 is rotated in the forward and reverse directions by the motor, the moving plate 17 moves in the arrow AB direction.

  Reference numeral 20 denotes an air cylinder whose cylinder end is pivotally attached to the moving plate 17 via a member 21, and a distal end portion of a rod 22 that can be advanced and retracted is pivotally attached to a central portion of a lever 24 via a member 23. The base end portion of the lever 24 is pivotally supported by the base plate 15 via a screw 25, and the swing end portion of a paper releasing cam 27 is pivotally attached to the swing end portion via a screw 26. Yes. A base end portion of the paper release cam 27 is pivotally supported by the moving plate 17 via a screw 28, and a cam surface 27a is formed on the lower surface so that a cam follower 32 of a paper discharge claw 5 to be described later contacts. Yes.

  The paper discharge claw 5 is provided so that the claw base 30 and the claw 31 face each other, and a turning force in the closing direction in which the tip of the claw 31 is pressed against the claw base 30 is applied by a spring member (not shown). At the same time, when the cam follower 32 comes into contact with the cam surface 27a of the paper releasing cam 27, the claw 31 is rotated in the opening direction by the cam action.

  In such a configuration, when the rod 22 of the air cylinder 20 is advanced, the lever 24 rotates in the clockwise direction in the figure around the screw 25, so that the paper release cam 27 rotates counterclockwise around the screw 28. As a result, the cam surface 27 a advances into the travel path of the paper discharge claw 5. When the paper discharge claw 5 travels in this state, the cam follower 32 comes into contact with the cam surface 27a, and the holding of the paper P by the paper discharge claw 5 is released by the cam action. The front end abuts on the front pad 11 and falls onto the first pile 6. Hereinafter, the state of the paper releasing cam 27 is referred to as a first state in which the paper held by the paper discharge claw 5 is brought into contact with the front pad 11 and discharged to the first pile 6.

  On the other hand, when the rod 22 of the air cylinder 20 is retracted, the lever 24 rotates counterclockwise around the screw 25 in the drawing, so the paper release cam 27 rotates clockwise around the screw 28, The cam surface 27 a is retracted from the travel path of the paper discharge claw 5 by being pulled up to a position indicated by a two-dot chain line in the drawing. When the paper discharge claw 5 travels in this state, the cam follower 32 does not come into contact with the cam surface, so the paper held by the paper discharge claw 5 passes through the front pad 11 while being held. Hereinafter, the state of the paper release cam 27 is referred to as a second state in which the paper held by the paper discharge claw 5 passes through the front pad 11 and is conveyed downstream in the paper conveyance direction of the first pile 6. Further, the paper pawl 5 travels in the direction of arrow A, the cam follower 32 of the paper ejection claw 5 comes into contact with the fixed cam of the paper releasing mechanism 9, and the paper P whose grip by the paper ejection claw 5 is released by the cam action is The front end contacts the front pad 13 and falls onto the second pile 7. As described above, the switching unit 10 is configured to switch the paper release cam 27 between the first state and the second state by the operation of the air cylinder 20.

  Next, the sheet-like object guide device 35 that is a feature of the present invention will be described with reference to FIGS. As shown in FIG. 4, the sheet-like material guide device 35 is provided in the vicinity of the front pad 11, and when the paper release cam 27 is in the second state by the switching unit 10, When the pair of sheet-like material guiding means 36 for guiding the paper P that has advanced and passed over the first pile 6 and the paper release cam 27 are switched from the first state to the second state. As a second restricting means that is positioned at the retracted position and is positioned at a restricting position that restricts the conveyance of the paper P on the upper side of the front pad 11 when the paper releasing cam 27 is switched from the second state to the first state. Four auxiliary pads 37 and a pair of air cylinders 38 as drive means for driving the sheet-like object guide means 36 are provided.

  As shown in FIG. 3, the pair of sheet-like material guiding means 36 and 36 are formed in a reverse shape and a reverse shape in plan view, and are attached to the inside of the left and right discharge frames 2 and 2. Engaging protrusions that are rotatably supported by the bases 40 and 40 via shafts 41 and 41 and engage with a cam member 45 as an engaged portion described later on the lower surface as shown in FIG. 36a is provided. The air cylinders 38 and 38 for driving the sheet-like material guiding means 36 are pivotally attached to fixed paper guides 43 attached to the left and right paper discharge frames 2 and 2 via stays 42, so that they can freely advance and retreat. The distal end portion of the rod 38a is pivotally attached to the proximal end portion side of the sheet-like object guiding means 36, that is, a portion close to the shaft 41. Therefore, when the rod 38a of the air cylinder 38 moves forward, the sheet-like material guiding means 36 rotates about the shaft 41 in the direction of arrow B as shown by the solid line in FIG. 3, and as shown in FIG. In addition, it advances above the front pad 11 and above the first pile 6. On the other hand, when the rod 38a of the air cylinder 38 is retracted, the sheet guide means 36 rotates in the direction of the arrow A about the shaft 41 as shown by a two-dot chain line in FIG. As shown in the drawing, the first pile 6 is retreated from the upper side to the downstream side in the paper conveyance direction.

  As shown in FIG. 4, the auxiliary pad 37 is formed in an inverted L shape when viewed from the side, is provided with a pad part 37 a on the swinging end side, and is formed in a substantially semicircular shape when viewed from the side. The cam member 45 is integrally attached, and a first cam surface 45a and a second cam surface 45b connected to the first cam surface 45a are formed around the cam member 45. The auxiliary pad 37 and the cam member 45 are rotatably supported via a shaft 47 on the other end side of the support plate 46 attached to the fixed paper guide 43 at one end side.

  As shown in FIG. 5A, the auxiliary pad 37 is always positioned under the front pad 11 by its own weight, retreats from the transport path of the paper P, and the cam member 45 is positioned upward. The first cam surface 45a of the cam member 45 is held in a state where the first cam surface 45a has advanced into the movement path of the sheet-like object guide means 36. The state where the abutting portion 37a of the auxiliary pad 37 is located below the front pad 11 and lower than the upper surface of the sheet guide means 36 is hereinafter referred to as a retracted position.

  When the rod 38a of the air cylinder 38 starts to retreat from the state where the auxiliary pad 37 is located at the retracted position, and the sheet-like object guide means 36 rotates in the direction of arrow A about the shaft 41 in FIG. As shown in (B), the sheet-like object guiding means 36 is engaged with the first cam surface 45 a of the cam member 45. Accordingly, the auxiliary pad 37 is held in a state where it is rotated counterclockwise by a certain angle against its own weight around the shaft 47. In this state, the abutting portion 37 a is located below the front abutting 11.

  Further, when the rod 38a of the air cylinder 38 is retracted, the sheet-like object guiding means 36 moves to the position indicated by the two-dot chain line in FIG. 3, and at this time, the engaging projection 36a of the sheet-like object guiding means 36 is changed to FIG. As shown to (C), it engages with the 2nd cam surface 45b of the cam member 45. FIG. Therefore, the auxiliary pad 37 further rotates counterclockwise about the shaft 47, and the pad part 37 a is positioned above the front pad 11. As described above, when the abutting portion 37 a of the auxiliary pad 37 is positioned above the front pad 11, the pad 37 a restricts the paper from passing above the front pad 11. Hereinafter, a state in which the auxiliary pad 37 is positioned above the front pad 11 and higher than the upper surface of the sheet guide means 36 is referred to as a restriction position. A guide roller 49 is rotatably supported by the fixed paper guide 43.

  Next, an operation of selectively discharging the paper P to the first pile 6 or the second pile 7 in the sheet-like material guide device having such a configuration will be described. First, the operation of discharging the paper P to the second pile 7 will be described. The switching means 10 of the paper release mechanism 8 provided above the first pile 6 is set to the second state in advance. That is, in FIG. 2, the rod 22 of the air cylinder 20 is retracted, and the lever 24 rotates about the screw 25 in the counterclockwise direction in the drawing, so that the paper release cam 27 rotates about the screw 28 in the clockwise direction. As a result, the cam surface 27 a is retracted from the travel path of the paper discharge claw 5.

  At the same time, the rod 38a of the air cylinder 38 advances and rotates in the direction of arrow B about the shaft 41 as shown by the solid line in FIG. 3, and as shown in FIG. Advances above the front pad 11 and above the first pile 6. In this state, the auxiliary pad 37 is positioned by its own weight at the retracted position, that is, the pad part 37 a is lower than the upper surface of the sheet-like object guiding means 36. In the second state, the abutting portion 37a may be positioned at the same height as the upper surface of the sheet-like object guiding means 36.

  In this state, the paper printed by the printing unit is held by the paper discharge claw 5 and conveyed in the direction of arrow A as the paper discharge chain 4 travels. When the paper discharge claw 5 reaches the paper release mechanism 8, the paper is switched. Since the means 10 is in the second state, the cam follower 32 of the paper discharge claw 5 does not contact the cam surface 27 a of the paper release cam 27. Therefore, the paper passes through the front pad 11 of the first pile 6 so that the paper bottom is guided by the sheet-like material guiding means 36 while being held by the paper discharge claw 5. Further, the paper discharge claw 5 traveling in the direction of arrow A has the cam follower 32 of the paper discharge claw 5 abutted against the fixed cam of the paper release mechanism 9 so that the grip by the paper discharge claw 5 is released and the front end of the paper P The front end comes into contact with 13 and falls onto the second pile 7.

  Next, the operation when switching from the state discharged to the second pile 7 to the state discharged to the first pile 6 will be described. To achieve this state, the switching means 10 of the paper release mechanism 8 is switched from the second state to the first state. That is, in FIG. 2, the rod 22 of the air cylinder 20 is advanced, and the lever 24 rotates around the screw 25 in the clockwise direction in the drawing, so that the paper release cam 27 rotates around the screw 28 in the clockwise direction. Then, it is pushed down to the position indicated by the solid line in the figure, and the cam surface 27 a advances into the travel path of the paper discharge claw 5.

  At the same time, the rod 38a of the air cylinder 38 starts to retract, and the sheet-like object guiding means 36 rotates in the direction of arrow A about the shaft 41 in FIG. By this rotation, the sheet-like object guiding means 36 is engaged with the first cam surface 45a of the cam member 45 as shown in FIG. Against this, it rotates counterclockwise by a certain angle.

  Further, when the rod 38a of the air cylinder 38 is retracted, the sheet-like object guiding means 36 moves to the position indicated by the two-dot chain line in FIG. 3, and at this time, the engaging projection 36a of the sheet-like object guiding means 36 is changed to FIG. As shown to (C), it engages with the 2nd cam surface 45b of the cam member 45. FIG. By this engagement, the auxiliary pad 37 further rotates counterclockwise about the shaft 47, and the pad part 37 a is located above the front pad 11 and higher than the upper surface of the sheet-like object guide means 36, that is, in the restricting position. Positioned.

  In this state, the paper P that has been carried by the paper discharge claw 5 is conveyed by the cam follower 32 of the paper discharge claw 5 coming into contact with the cam surface 27a of the paper release cam 27. The holding of P is released, and the front end comes into contact with the front pad 11 so that it falls onto the first pile 6. Here, when the paper P is a thick paper having a relatively high weight or the like, the paper P which has been released from the grip tries to get over the front pad 11 due to inertia, but the sheet-like material guiding means 36 on the upper side of the front pad 11. Since the auxiliary pad 37 that has advanced to a position higher than the upper surface of the auxiliary pad 37 is provided, the paper P is brought into contact with the pad 37a of the auxiliary pad 37 and is restricted from being transported. It falls on the first pile 6.

  As described above, since the auxiliary pad 37 that restricts the conveyance of the paper is provided on the upper side of the front pad 11, the paper can be prevented from getting over the front pad 11, so that the paper P is placed on the first pile 6. It can be loaded reliably. Further, since the auxiliary pad 37 is indirectly driven by the air cylinder 38 via the sheet-like material guiding means 36, both the members can be driven by one driving means, so that the structure is simplified and the manufacturing cost is reduced. can do.

  In addition, since the operation of the sheet-like material guiding unit 36 and the operation of the auxiliary pad 37 are linked, the timing of the operation of the auxiliary pad 37 to the restricted position and the operation of retracting the sheet-like material guiding unit 36 are performed. Therefore, the burden on the operator can be reduced. In addition, since the sheet-like material guiding unit 36 and the auxiliary pad 37 are interlocked, when the switching unit 10 switches from the second state to the first state, the auxiliary pad 37 is positioned at the restricted position in a timely manner. Therefore, the paper P can be reliably stacked on the first pile 6.

  Further, in order to move the auxiliary pad 37 to the restricting position in accordance with the movement of the sheet-like material guiding means 36, an engaging portion 36a that engages with the cam member 45 provided integrally with the auxiliary pad 37 is provided. Since the guide means 36 is provided, the number of parts can be minimized and the structure can be simplified. Further, since the rod 38a of the air cylinder 38 for moving the sheet-like material guiding means 36 is pivotally attached to the base end side of the sheet-like material guiding means 36, that is, a portion close to the shaft 41, the lever action As a result, the moving speed of the sheet guide means 36 can be made faster than the advance / retreat speed of the rod 38a. For this reason, the switching operation between the retracted position and the restricting position of the auxiliary pad 37 that is linked to the sheet-like material guiding means 36 becomes faster, so that erroneous discharge of the paper P to the first pile 6 and the second pile 7 is prevented. be able to.

  5 and 6 show a second embodiment of the present invention. FIG. 5 is a plan view, FIG. 6 is a side view, and FIG. FIG. 5B shows a state in which the paper passing over the pile is guided, FIG. 5B shows a state in which the sheet-like material guiding means is retracted from above the pile, and FIG. The means has been retracted from above the pile, and the second restricting means is positioned at the restricting position.

  In the second embodiment, the auxiliary pad 50 as the second restricting unit is rotatably supported by the sheet-like material guide unit 36, and the auxiliary pad 50 contacts the one end 46 a of the support plate 46. Is rotated and positioned at the restriction position. That is, as shown in FIG. 5, a notch 36 b is provided in a part of the sheet-like material guiding means 36, and the base end portion 50 a of the auxiliary pad 50 rotates through the shaft 51 in the notch 36 b. It is supported freely. The auxiliary pad 50 is formed in an L shape by a base end part 50a and a pad part 50b orthogonal to the base end part 50a, and the pad part 50b is always below the front pad 11 from the upper surface of the sheet-like material guiding means 36 by its own weight. Is positioned at a lower position, and is positioned at a retracted position retracted from the transport path of the paper P. In the second state, the abutting portion 50b may be positioned at the same height as the upper surface of the sheet-like object guiding means 36.

  In such a configuration, when discharging the paper P to the second pile 7, the switching means 10 of the paper release mechanism 8 is set to the second state, and the paper release is performed as in the first embodiment described above. The cam surface 27a of the cam 27 is retracted from the travel path of the paper discharge claw 5, and as shown in FIG. 6 (A), the sheet-like material guiding means 36 is located above the front pad 11 and the first pile 6 Advance to the upper side. In this state, the auxiliary pad 37 is positioned at the retracted position by its own weight. Accordingly, the paper held by the paper discharge claw 5 passes above the front pad 11 while the paper edge is guided by the sheet-like object guiding means 36 while the paper holding claw 5 is held. Falls on the pile 7.

  On the other hand, when switching from the state discharged to the second pile 7 to the state discharged to the first pile 6, the switching means 10 of the paper release mechanism 8 is switched from the second state to the first state. Similar to the first embodiment, the cam surface 27 a of the paper release cam 27 is advanced into the travel path of the paper discharge claw 5. At the same time, the rod 38a of the air cylinder 38 starts to move backward, and the sheet-like material guiding means 36 moves in the direction of arrow A as shown in FIG. By this movement, the base end portion 50a of the auxiliary pad 50 rotatably supported by the sheet-like object guiding means 36 is engaged with the one end 46a of the support plate 46, and the auxiliary pad 50 has its own weight around the shaft 51. Against this, it rotates counterclockwise by a certain angle.

  Further, when the rod 38a of the air cylinder 38 is retracted, the auxiliary pad 50 further rotates clockwise, and the base end part 50a of the auxiliary pad 50 rides on the upper surface of the support plate 46, so that the pad part 50b moves upward. It is oriented and positioned at a position higher than the upper surface of the sheet-like material guiding means 36 above the front pad 11, that is, at a restriction position. Therefore, even if the paper released from the catch of the paper discharge claw 5 is thick paper or the like having a relatively heavy weight, the front end of the paper is placed on the contact portion 50b of the auxiliary contact 50 as in the first embodiment described above. Since it abuts, it falls on the first pile 6 without passing the upper side of the front pad 11. In the second embodiment, the auxiliary pad 50 is rotatably supported on the existing sheet-like object guiding means 36, and the auxiliary pad 50 is brought into contact with one end 46a of the existing support plate 46, thereby assisting. Since the abutment 50 is positioned at the restriction position, the number of parts can be minimized and the structure can be simplified.

  In the present embodiment, the sheet-like material guide device having two piles has been described. However, the sheet-like material guide device may have three or more piles, or one pile and one pile. The present invention can also be applied to a sheet-like material guiding apparatus in which a sheet-like material is stacked or passed without being stacked. Further, although the auxiliary pad 37 is positioned at the retracted position by its own weight, it may be positioned using a biasing member such as a torsion coil spring. Moreover, although the sheet-like material has been described with an example using paper, a sheet-like film such as vinyl chloride may be used.
