Description

The present invention relates to a sheet collecting device for stacking and collecting sheet products conveyed from a conveying device, and a sheet conveying and collecting system combining the sheet conveying device and the sheet collecting device. Furthermore, the present invention relates to a sheet collecting method using a sheet collecting device.

In the manufacturing process of paper sheets, films, steel sheets, etc., a long web is cut into a predetermined size and processed into sheets. The sheet moves along the conveying direction on a conveying surface composed of an endless belt, a plurality of rotating rollers, etc., and is collected downstream.

An inspection device is installed on the conveying path of a single-sheet conveying device, and substandard products that are judged to be out of specification by the inspection are guided to a conveying route different from that of non-conforming products that are judged to be within the standard. can selectively collect only non-defective products. For example, the conveying apparatus of Patent Document 1 has a switching gate at a connection portion between conveyors that carry out horizontal conveying. It is configured to guide the sheet to the conveyor. In such a conveying apparatus, non-standard products are horizontally conveyed on the conveying surface and collected in a non-conforming product collection section downstream of the conveying path, and non-standard products slide down the conveying surface and are accumulated and collected.

The method of guiding the non-standard product below the conveying surface utilizes the sliding of the sheet due to gravity, so that the conveying route can be switched smoothly. Therefore, when a defective sheet is conveyed onto the conveying path, it is not necessary to stop conveying to switch the sheet conveying path, and the efficiency of sorting and collecting sheet products can be improved.

JP-A-8-119491

When non-standard sheets are sorted by guiding them below the conveying surface, the sheets guided downward are urged by gravity, and the sheets may be damaged or deformed when they collide with a collection box or the like during collection. Cheap. If the sheet guided downward is a defective product that is scheduled to be discarded, there is no particular problem even if it is damaged or deformed. On the other hand, if the sheet to be guided below the conveying surface is inferior in quality to a non-defective product but usable as a product (so-called B grade product), the sheet can be handled without lowering the product value due to breakage or deformation. must be collected.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet collecting device capable of collecting sheets moving on a conveying surface of a conveying device without impairing product value.

According to the present invention, the sheet moves from the upstream side to the downstream side along the first direction on the conveying surface, and the sheet guided below the conveying surface is accumulated and collected in the sheet collecting body positioned below the conveying surface. The present invention relates to a sheet collecting method and a sheet collecting device used therein. The sheet collecting device includes a sheet moving direction guide and a sheet stacking/collecting body. The sheet moving direction guide receives the sheet moving in the first direction from the upstream side to the downstream side and changes the moving direction. The sheet accumulating and collecting body receives the sheets moving from the sheet moving direction guide and flatly collects them.

It is preferable that the movement direction guide body has a placement surface for receiving the sheet inclined downward from the minus side toward the plus side along the second direction orthogonal to the first direction. It is preferable that the mounting surface of the movement direction guide member is inclined downward along the first direction from the upstream side toward the downstream side. The sheet collection body is positioned below the mounting surface of the movement direction guide body and on the positive side in the second direction.

It is preferable that the moving direction guide has a curved surface portion that rises toward the downstream side at the downstream end of the mounting surface in the first direction. By providing the rising curved surface at the downstream end of the placement surface, it is possible to reduce the momentum of the sheet in the first direction and promote the movement of the sheet to the sheet collecting body.

It is preferable that the sheet collection body has a stacking surface that receives the sheets guided from the movement direction guide body and is inclined so as to descend from the negative side toward the positive side along the second direction. It is preferable that the stacking surface of the collected sheet body is inclined downward along the first direction from the upstream side toward the downstream side. Since the stacking surface of the sheet collection body is inclined, the impact when the sheets moving from the moving direction guide come into contact with the stacking surface can be reduced, and damage and deformation of the sheets can be further suppressed.

It is preferable that an upright wall surface for receiving the sheet guided from the moving direction guide is provided at the positive end in the second direction of the stacking surface of the sheet collection body. By providing an upright wall surface at the end in the second direction, the stacking position of the sheets on the stacking surface can be stabilized, and the efficiency of the sheet collection work can be improved.

Further, the present invention relates to a sheet conveying and collecting system comprising a sheet conveying device and the above sheet collecting device.

The sheet collection device changes the movement direction of the sheet by the action of a movement direction guide body having an inclined mounting surface, and guides the sheet onto the stacking surface of the sheet collection body. Therefore, even if the sheet guided downward from the sheet conveying surface of the sheet conveying device is urged by gravity, the impact of contact between the sheet collecting body and the sheet is small, and the product is damaged or deformed during sheet collection. Decrease in value can be suppressed.

FIG. 1 is a schematic perspective view of a sheet conveying and collecting system according to one embodiment. 2 and 3 are respectively a plan view and a front view of the sheet conveying and collecting system. The sheet conveying and collecting system includes a sheet conveying device 10 and a sheet collecting device 50 composed of a moving direction guide 30 and a sheet collecting body 40 . FIG. 4 is an xz sectional view of the sheet collecting device 50 along line IV-IV.

The sheet conveying device 10 moves from the upstream side (−y side) to the downstream side (+y side) in the first direction (y-axis direction), which is the conveying direction, on a conveying surface configured by a plurality of rollers 11. Convey the sheet 2. The sheet 2 is, for example, an optical film such as a polarizing plate.

The sheet 5 that has reached the downstream end of the conveying surface is flattened and collected in a sheet collection box 20 positioned below the conveying surface by gravity drop. If the sheet collection box 20 is provided in the vicinity of the downstream end of the conveying surface, the sheet 5 will first reach the stacking surface 21 of the sheet collecting box 20 or onto the stacking surface before it completely separates from the conveying surface and freely falls. It contacts with the sheets 26 stacked on the stacking surface 26, and is stacked so as to slide on the stacking surface 21 (or on the sheets previously stacked on the stacking surface). Therefore, the impact when the sheets 5 and the sheet collection box 20 contact each other is small, and the sheets are less likely to be damaged or deformed due to the impact during collection.

An inspection device 83 is provided on the upstream side of the sheet conveying device 10 to inspect the sheet. The examination information is stored in the storage unit 85 . The inspection information of each sheet stored in the storage unit 85 is transmitted to the control unit 88 . The control unit 88 sends a path change signal to the sheet path change mechanism when a film having specific inspection information (eg, quality abnormality) reaches the vicinity of the rollers 15 forming the transport surface. Upon receiving the path change signal, the sheet path change mechanism operates to move the sheet 2 downward (-z side) on the conveying surface.

In the sheet conveying device 10 shown in FIG. 1, an air blowing device 18 is provided above (on the +z side) the conveying surface between the rollers 15 and 16 as a sheet path changing means. The air blowing device 18 blows air downward when the sheet 103 having specific inspection information reaches the roller 15 . Since the sheet 103 is flexible, it is bent downward by air blowing from above, guided below the roller 16, and discharged below the sheet conveying surface.

The sheet guided below the sheet conveying surface retains the momentum toward the downstream side (+y side) in the first direction on the conveying surface, and further moves vertically downward (− z side) is given. A sheet 104 having momentum in the +y direction and the −z direction is received by the mounting surface 31 of the moving direction guide 30 of the sheet collecting device 50 . When the sheet received by the mounting surface 31 of the moving direction guide 30 moves on the mounting surface 31, the positive side (+x side) momentum in the second direction is imparted to the sheet, and the moving direction of the sheet changes. .

As shown in FIG. 5, the mounting surface 31 is inclined downward from the −x side toward the +x side along the second direction (x-axis direction) perpendicular to the first direction (y-axis direction). (inclination angle α in the x-axis direction). If the loading surface 31 is inclined downward from the −x side toward the +x side, the sheet 104 on the loading surface 31 is moved by the action of gravity to the positive side ( +x side) momentum is given, and the movement direction changes. The sheet 104 to which the momentum in the second direction has been applied is located vertically below (-z side) and on the positive side (+x side) of the second direction the sheet recovery body 40 with respect to the placement surface 31 of the movement direction guide body 30. recovered within.

FIG. 6 is a plan view of a conventional sheet conveying and collecting system, and FIG. 7 is a front view of the conventional sheet conveying and collecting system. The system shown in FIGS. 6 and 7 includes a sheet conveying device 10 similar to the system shown in FIGS. The sheets are stacked flat in the sheet collection box 20 and collected.

The conventional sheet conveying and collecting system and the sheet conveying and collecting system of the present invention differ in the method of collecting the sheets guided below the conveying surface. In the conventional sheet transport and collection system, the sheet 204 guided below the transport surface by the sheet path changing mechanism 18 based on the inspection results upstream of the transport path is collected by the sheet collection box 240 provided below the transport surface. be recovered.

Rollers and their power mechanisms are arranged below the sheet conveying surface, and the sheet collection box 240 is arranged away from the sheet conveying surface in order to avoid positional interference with these devices. ing. The sheet 204 guided below the conveying surface is provided on the stacking surface 241 of the sheet collection box 240, on the sheet 246 previously stacked on the stacking surface, or on the end of the stacking surface 241 on the +y side. It collides with the upright wall surface 243 . Since the sheet collection box 240 is arranged away from the conveying surface, the sheet 204 is urged by gravity while falling downward. Therefore, when the sheet 204 is collected by the sheet collection box, the movement speed of the sheet 204 is high, and the sheet 204 is loaded on the stacking surface 241 of the sheet collection box 240, the sheet 246 previously stacked flat on the stacking surface 241, or the standing sheet 204 is loaded. The sheet may be deformed, scratched, or the like due to the impact when it collides with the wall surface 243 .

If the sheet guided below the conveying surface is a defective product that is scheduled to be discarded, there is no particular problem even if the sheet is deformed or scratched during recovery in the sheet recovery box. On the other hand, if the sheet guided below the conveying surface can be used as a product, it is necessary to reduce the collision during collection in order to prevent the product value from being lowered due to damage or deformation.

The sheet conveying and collecting system of the present invention is provided with a sheet collecting device 50 below the sheet conveying surface, and the sheet guided downward from the sheet conveying surface of the sheet conveying device 10 is moved to the moving direction guide 30 and the sheet collecting unit 40. Receive and collect in two stages. Therefore, even if the sheet guided below the conveying surface is urged by gravity, the speed in the sheet moving direction (x direction) when collected by the sheet collecting body 40 is small, and deformation, damage, etc. due to collision may occur. can be prevented.

A sheet collection method by the sheet collection device 50 will be described below with reference to FIGS.

As shown in FIG. 5A, the sheet 104 guided downward from the sheet conveying surface contacts the mounting surface 31 of the moving direction guide 30 arranged below the conveying surface. In addition to the momentum in the +y direction on the conveying surface, the sheet 104 has momentum in the −z direction due to gravity when it slides down from the conveying surface. The short side of the sheet contacts the mounting surface 31 in a falling attitude with the falling leading edge.

If the placement surface 31 of the moving direction guide 30 is inclined along the y-axis direction so as to fall from the -y side toward the +y side, the sheet is in a falling posture with the side on the +y side as the falling edge. 104 lands on the mounting surface 31 at a small angle as if sliding. Therefore, the sheet 104 is less likely to be damaged or deformed due to contact with the moving direction guide 30 .

When the placement surface 31 of the movement direction guide 30 is inclined along the x-axis direction so as to descend from the -x side toward the +x side, as schematically shown in FIG. A force in the +y direction and a force in the +x direction are applied by gravity to a point P at which the sheet 104 moving to the side contacts the mounting surface 31, and the sheet 104 is given momentum in the +x direction. That is, since the placement surface 31 of the moving direction guide 30 is inclined in the x-axis direction, the sheet 104 received by the placement surface 31 moves in the +x direction.

In order to promote movement of the sheet 104 in the x direction, the inclination angle α of the placement surface 31 in the x-axis direction is preferably 3° or more, more preferably 5° or more. If the inclination angle is excessively large, the sheet may be damaged or deformed due to the impact when the sheet comes into contact with the sheet collecting body due to the increased momentum in the x direction. Therefore, the inclination angle α is preferably 40° or less, more preferably 30° or less.

As shown in FIG. 5A, the +x side edge of the placement surface 31 of the moving direction guide 30 is located on the -x side of the +x side edge of the sheet 104 guided below the conveying surface. When the sheet 104 is positioned, as shown in FIG. 5B, the −x side area is received by the mounting surface 31 of the moving direction guide 30, and the +x side area does not contact the mounting surface 31. . At the point P where the sheet 104 and the mounting surface 31 are in contact with each other, normal force from the mounting surface 31 acts on the sheet 104, whereas at the point Q which is not in contact with the mounting surface, the force of gravity is applied. There is no counteracting force against Therefore, the sheet 104 moves in the +x direction due to the action of the moment.

When the +x side edge of the placement surface 31 of the movement direction guide 30 is located on the -x side of the +x side edge of the sheet 104 guided below the conveying surface, the placement surface 31 A momentum in the +x direction can be imparted to the sheet moving on the placement surface 31 even if the sheet is not inclined along the x-axis direction. The +x side edge of the loading surface 31 is located on the -x side of the +x side edge of the sheet 104 guided below the conveying surface, and the loading surface 31 is positioned from the -x side to the +x side. If the sheet 104 is inclined along the x-axis direction so as to descend toward the +x-direction, the movement of the sheet 104 in the +x-direction becomes smoother.

In the xy plane, when the edge 32 on the plus side of the second direction of the mounting surface 31 is non-parallel to the y-axis direction and is inclined so that the x-coordinate on the downstream side (+y side) becomes smaller (Fig. 2), as the sheet 104 moves in the +y direction, the area of the sheet 104 in contact with the stacking surface 31 on the −x side becomes smaller, and the non-contact area with the stacking surface on the +x side becomes larger. Therefore, the movement of the sheet 104 in the +x direction due to the action of the moment is further promoted.

The sheet 104 imparted with momentum in the +x direction moves to the sheet collecting body 40 positioned below and on the +x side of the placement surface 31 of the moving direction guide 30, as shown in FIG. 5C. That is, the moving direction guide 30 moves the sheet 104 onto the stacking surface 41 of the sheet recovery unit 40 while moving in the x-axis direction perpendicular to the moving direction (y-axis direction) when dropped from the conveying surface. be guided.

The sheet guided onto the stacking surface 41 of the sheet recovery body 40 contacts the stacking surface 41 in a falling posture with the +x side (the long side of the rectangular sheet in FIG. 5) as the falling tip. If the stacking surface 41 is inclined downward from the −x side toward the +x side along the x-axis direction, the sheet 104 in the falling posture with the side on the +x side as the falling tip slides onto the stacking surface 41 . Since the sheet 104 lands at such a small angle, the sheet 104 is less likely to be damaged or deformed due to contact with the stacking surface 41 . Further, if the stacking surface 41 is inclined downward from the −y side toward the +y side along the y-axis direction, the angle at which the long side of the sheet 104 that is the drop tip contacts the stacking surface 41 is Since it is small, the sheet 104 is less likely to be damaged or deformed due to contact with the stacking surface 41 of the sheet collection body 40 .

It is preferable that the mounting surface 31 is provided with a rising curved portion at the +y direction end. When the sheet 104 rides on the rising curved surface 33 at the end in the +y direction, the momentum in the y direction is reduced, and the movement of the sheet 104 is predominantly in the x direction. By reducing the momentum in the y direction (stopping the movement in the y direction) of the sheet 104 that has run on the rising curved surface 33, the sheet 104 moving on the mounting surface 31 is moved to the +x direction stack at a fixed position. It can be moved and stacked on the surface 41 . Since the rising portion of the +y-direction end of the mounting surface 31 has a curved surface shape, the momentum of the sheet 104 in the y-direction can be reduced without generating an impact due to the collision between the +y-direction end of the sheet and the rising portion. can be reduced.

The sheet 104 guided onto the stacking surface 41 of the sheet collection body 40 is further moved in the +x direction and then stopped to be stacked and collected on the stacking surface 41 as shown in FIG. 5(D). An upright wall surface 42 with which the sheet 104 can abut is preferably provided at the +x side end of the stacking surface 41 . Since the standing wall surface 42 is provided, the sheet 104 moved from the moving direction guide 30 can be stopped at a predetermined position and stacked flat on the stacking surface 41 .

The upright wall surface 42 provided at the +x direction end of the sheet collection body 40 extends parallel to the extending direction of the second direction plus side edge of the placement surface 31 of the moving direction guide 30 . preferably. If the standing wall surface 42 is parallel to the edge of the placement surface 31, the impact when the leading edge of the sheet 104 moved from the moving direction guide 30 hits the standing wall surface 42 is reduced. Therefore, damage and deformation of the sheet are suppressed. Further, since the posture of the leading end of the sheet 104 when it hits the standing wall surface 42 is stabilized, the stacking position of the sheets in the sheet collecting body 40 is stabilized, and a plurality of sheets stacked in the sheet collecting body 40 can be easily collected. Become.

As described above, the sheet collecting device 50 receives the sheet 104 by the mounting surface 31 of the moving direction guide 30 and imparts momentum to the sheet in the x direction as the sheet moves on the mounting surface 31 . As a result, the sheet 104 moves in the x direction and is stacked flat on the stacking surface 41 of the sheet collection body 40 . As described above, in the sheet collecting device 50, the movement direction guide member 30 changes the movement direction of the sheet, so that the falling edge of the sheet 104 received by the sheet collecting member 40 is the same as the falling edge of the sheet when it falls from the conveying surface. is different from Therefore, in the sheet collecting method of the present invention, even if the sheet collecting device 50 is arranged at a position away from the sheet conveying surface and the sheet guided downward from the conveying surface is urged by gravity, the sheet cannot be collected. It is possible to suppress the damage and impact caused by the impact during collection by the body 40. - 特許庁

The sheets accumulated in the sheet collecting body 40 are moved to another place and supplied to the next process. The next process includes inspection, packing/shipping, bonding with other members (for example, an image display panel such as a liquid crystal cell), and the like. Sheets may be moved from the sheet collecting body to another location by using an appropriate automatic conveying device or the like, or by hand-carrying by an operator.

As shown in FIG. 6, when a worker manually carries the sheets stacked in the sheet collection box 240 located directly under the conveying surface, it is necessary to get under the conveying surface and collect the sheets accumulated in the box. There is On the other hand, in the sheet collection device 50, as shown in FIG. 3 and FIG. A sheet collecting body 40 can be arranged. Therefore, in the method of the present invention, the sheets accumulated in the sheet collecting body 40 can be easily collected, and work safety can be enhanced.

As described above, in the sheet conveying and collecting system shown in FIG. 1, the flexible sheet guided below the conveying surface is collected by the sheet collecting device 50. However, the present invention is not limited to the above embodiment.

The sheet collecting device 50 of the present invention changes the moving direction of the sheet by using the inclination of the placement surface 31 of the moving direction guide 30 and collects the sheet by the sheet collecting unit 40 . Such a sheet collection method can be applied to sheets other than sheets discharged below the conveying surface by the action of the sheet path changing mechanism. For example, the sheet collection device of the present invention may be used instead of the sheet collection box 20 to collect the sheets that have reached the downstream end of the conveying surface. As described above, at the downstream end of the transport surface, a sheet collection box can be arranged near the transport surface. Therefore, the acceleration of the sheet due to gravity is smaller than that of the sheet discharged below the conveying surface, but the use of the sheet collecting device of the present invention can further suppress breakage and deformation during collection.

The sheet conveying surface of the sheet conveying device is preferably a horizontal surface, but may be an inclined surface. For example, the sheet may be conveyed by a roller conveyor (gravity conveyor) whose conveying surface is inclined from the upstream side to the downstream side. The sheet conveying means is not limited to the rotating roller, and the sheet conveying surface may be configured by an endless belt or the like.

The sheet path change mechanism that guides the sheet on the conveying surface downward is not limited to the air blowing method. For example, a presser roller that can move up and down is provided above the conveying surface, and when a sheet to be guided downward is conveyed and the leading edge of the sheet reaches directly below the presser roller, the presser roller is lowered from above to press the sheet downward. may be guided below the conveying plane.

The sheet may be guided downward by deforming the conveying surface of the sheet conveying device. For example, as shown in FIG. 8, by moving the rotating shaft 116 of the conveyor downward, the conveying surface formed by the endless belt 110 wound around the rotating shafts 115 and 116 is tilted so that the sheet on the conveyor is moved downward. 103 can be led downwards. Further, as shown in FIG. 9, by moving the rotary shaft 125 of the conveyor upward, the conveying surface formed by the endless belt 120 wound around the rotary shafts 125 and 126 is inclined, and the sheet 103 is conveyed downwardly. may lead to

The sheet guided below the conveying surface may be directly guided from the conveying surface onto the mounting surface 31 of the moving direction guide 30, and after being guided onto the guide once, the sheet may be guided onto the mounting surface of the moving direction guide. may be accepted. Further, as shown in FIG. 8, after the sheet 103 slides down the inclined conveying path (endless belt 110), it may be received by the placement surface of the moving direction guide.

Sheets to be guided below the conveying surface and sheets to be conveyed to the downstream end of the conveying surface without being guided downward may be sorted according to a predetermined criterion. Selection criteria are not particularly limited. For example, if the inspection results of an inspection device provided upstream of the sheet conveying device are acceptable (A grade product), the sheet is conveyed to the downstream end of the conveying surface and collected in the sheet collection box 20 to satisfy the acceptance criteria. It suffices to guide those (B-class products) that do not have any but have product value (B-grade products) below the conveying surface and collect them into the sheet collecting body 40 of the sheet collecting device 50 . By using the sheet collecting device 50 of the present invention, it is possible to prevent damage and deformation of the sheet products guided below the conveying surface. Therefore, the A-grade product may be guided below the conveying surface and recovered into the sheet recovery body 40 of the sheet recovery device 50 .

The conveying device may include a plurality of sheet path changing mechanisms along the conveying direction. For example, a sheet path changing mechanism provided on the upstream side of the conveying path guides products that fail inspection below the conveying surface, and a sheet path changing mechanism provided on the relatively downstream side guides Class B products below the conveying surface. may lead to Three or more path change mechanisms may be provided along the transport direction of the transport device.

The inspection method on the upstream side of the sheet conveying device may be automatic inspection by the inspection device 83 or visual inspection by an inspector. When the sheet is an optical film, the items to be inspected include parts containing foreign substances such as foreign matter, air bubbles, and stains; deformed parts such as dents and scratches; film thickness, optical properties, and the like.

A sheet cutting device may be provided upstream of the sheet conveying device. For example, a sheet product unwound from a roll of a long web may be cut into a predetermined size by a sheet cutting device and then conveyed onto the conveying surface of the sheet conveying device. In this case, the inspection may be performed before or after cutting. A pre-inspected long web may be unwound from the roll and cut to a predetermined size by a cutting device. Defect position information obtained by preliminary inspection is stored in a storage unit, and the position information (y coordinate) of the sheet cut by the cutting device is compared with the defect position information stored in the storage unit. However, when a defective sheet is conveyed, the sheet path changing mechanism may be operated to guide the sheet below the conveying surface.

1 to 5 show an example in which a sheet is cut so that the long side of a rectangle is in the conveying direction (y direction) and the short side is in the width direction (x direction). The sheet may be cut so that the short side and the width direction are the long sides. When a sheet cut so that the long side of a rectangle in the width direction is guided below the conveying surface, the sheet is placed on the movement direction guide body 30 in a falling attitude with the long side of the rectangle as the falling tip. After being received by the placing surface 31, the moving direction is changed, and the collected sheet is received by the stacking surface 41 of the collected sheet in a falling attitude with the short side of the rectangle as the falling tip, and is flatly collected.

When the size or cutting direction of the flexible sheet changes, the curved shape and the amount of curved may change. By using the sheet collecting device of the present invention, regardless of the shape or amount of curvature of the sheet, the sheet is received by the moving direction guide body, the moving direction of the sheet is changed to reduce the speed, and then the sheet is collected by the sheet collecting body. can lead. The sheet collecting device of the present invention is applicable not only to collecting flexible sheets such as optical films, but also to collecting rigid sheets such as steel plates.

In the sheet conveying and collecting system of the present invention, the sheet collecting device 50 may be fixed to the sheet conveying device 10 or may be provided so as to be separated from the sheet conveying device 10 . The movement direction guide member 30 and the sheet recovery member 40 of the sheet recovery device 50 may be integrally fixed or may be separated. For example, the sheet collection device 50 may be configured to be movable by providing wheels 38 , 48 or the like on the lower portions of the movement direction guide member 30 and the sheet collection member 40 . If the movement direction guide body 30 is configured to be movable, the position and angle of the edge 32 of the placement surface 31 can be easily adjusted, so optimization according to the sheet cutting direction, size, dropping posture, etc. becomes possible. Further, by adjusting the position of the collected sheet body 40 according to the arrangement of the moving direction guide 30, it is possible to reduce the damage or deformation of the sheets moving from the moving direction guide to the collected sheet body 40.
