Description

  The present invention relates to a device for intermittently feeding a folded sheet member and a developing device for developing the sheet member in conjunction with the intermittent device, and more particularly, to a sheet bundle in which a plurality of sheet members are stacked. The present invention relates to a device capable of intermittent supply or development.

  In the processing of industrial products, some require intermittent supply of sheet members, and in OA equipment, intermittent supply of sheet members for use in printing or the like may be required. However, these supply devices are generally a mechanism that takes out one sheet at a time from a sheet member stacked in a lump or a bundle and supplies it. Then, one sheet member taken out (separated) from the mass or bundle is intermittently supplied. For example, when the special paper in the OA equipment is intermittently supplied, a part of the lump of the sheet member is levitated, and on the other hand, the floating is regulated so that one sheet member is separated from the lump and the specific lump is separated. There has been a technique for transporting one sheet member using a transport element (see Patent Document 1). Also, in the field of foods, a technology for storing a layer of laver sheets vertically in a storage case and feeding one laver sheet taken out by a suction head with a driving roller when supplying the laver. (See Patent Document 2).

  However, although the above-described technique is considered to be one mode of an intermittent sheet supply device for sheet members, a predetermined number of sheet members (hereinafter, referred to as a sheet bundle) are stacked while maintaining the stacked state. It was not an intermittent supply (the entire sheet bundle). In particular, in the folded sheet bundle, the shape (edge shape) of the bent portion (bent portion) is greatly different from that of the other portion, and it is extremely difficult to automate the transfer. there were.

  Further, in a processing site using a folded sheet bundle, a step of returning (deploying) the bent portion of the sheet bundle is often required. For example, a seaweed bundle received from a fishery industry is grilled. It was developed during the production of laver and sent to a heating device. At that time, when the sheet bundle is transferred to the processing device, the operation of supplying the folded sheet bundle (seaweed bundle) and expanding the sheet bundle cannot be automated. Was done by hand.

  Various technologies have been developed in the laver folding and bundling processes, and a device for detaching the laver from the laver bundle when the laver is distorted (see Patent Document 3) and a device for removing irregular laver (See Patent Document 4, for example), but these are intended to recover defective products, and do not intermittently supply and develop a laver bundle.

  As described above, it is extremely difficult to automate a process of intermittently supplying a sheet bundle in which a plurality of sheet members are stacked in a state of being folded in two, and further expanding and transferring the sheet member to a processing apparatus. Was. For this reason, the process was forced to be performed manually, but the process was delayed compared to the speeds of the transport and processing steps before and after the process, and thus became a bottleneck in the entire processing process. . In addition, there is a further difference in speed between a skilled person and a beginner in the process, and there has been a long-awaited need for automation of the process while the number of skilled people tends to decrease in recent years.

  The present invention has been made in view of the above points, and an object thereof is to provide an apparatus capable of intermittently supplying a sheet bundle in which a plurality of sheets are stacked in a folded state, The invention is to provide a device that is developed in conjunction with the system.

  Therefore, the present invention relating to an intermittent sheet supply device for a sheet member is an apparatus for intermittently supplying a sheet bundle formed by stacking a plurality of sheet members in a state of being folded in two, and bending each sheet bundle. With the section facing downward and the generatrix direction of the bent portion being parallel, a stocker for aligning a plurality of sheet bundles, and pressing the sheet bundle aligned with the stocker in a direction orthogonal to the generatrix direction of the bent portion A holding portion for holding one bundle of sheet bundles with the bent portion facing down in the vicinity of the edge of the stocker with respect to the pressing direction of the pressing portion; and a holding portion for one bundle held by the holding portion. An extruding portion for extruding the sheet bundle in a generatrix direction of the bent portion.

  According to the above configuration, the sheet bundle with the bent portion facing down is aligned on the stocker, and in this state, the sheet bundle is pressed by the pressing portion in a direction perpendicular to the generatrix direction of the bent portion. Therefore, the outermost sheet members of the sheet bundle arranged adjacent to each other can be sequentially moved in the pressing direction while contacting each other. Since a holding unit for holding one bundle of sheets is provided near the edge of the stocker, the sheet bundle sequentially moved by the pressing of the pressing unit is held by the holding unit at the edge of the stocker. And is separated by one bundle. Further, since the pushing section pushes out one bundle of sheets held in the holding section in the generatrix direction of the bent section, the pushing section pushes the sheet bundle from the stocker and the holding section without being affected by other sheet bundles arranged in the stocker. Can be moved outward.

  In the invention according to the intermittent sheet member feeding device having the above-described configuration, the holding portion supports at least one portion on both sides of the lowermost end of the bent portion on the surface of the outermost sheet member forming the sheet bundle. It is possible to adopt a configuration that includes a supporting region.

  In the case of such a configuration, the holding unit holds one bundle of sheet members in a state where both sides thereof are supported within a range where the sheet member is bent. The outer cross-sectional shape of the bent portion of the sheet member is approximately circular or elliptical, and its lowest point is a point of contact with a horizontal straight line. Due to the contact and support, the sheet bundle can be arranged at the center of the holding section (the center of the support area). This enables simple positioning of the held sheet bundle.

  Further, in the invention according to the intermittent sheet member feeding device having the above-described configuration, the holding portion may be formed in a substantially V-shaped, substantially U-shaped, or substantially semicircular gutter shape in cross section.

  In the case of the above configuration, since the support area is linearly supported along the generatrix direction of the bent portion, frictional resistance is reduced by line contact, and the sheet bundle moves (slids) in the generatrix direction. ) Has made it easier. This is remarkable in the case of a gutter shape having a substantially V-shaped cross section. On the other hand, in the case of a substantially U-shaped gutter shape, the sheet bundle may be supported at a plurality of places or an appropriate range on both sides of the lowermost end of the bent portion. Although the frictional resistance of (a) slightly increases, the holding state of the sheet bundle can be stabilized.

  In each of the above-described inventions related to the intermittent sheet member feeding device, the holding unit is provided at a lower position than the stocker, and the one sheet bundle is moved from the edge of the stocker to the holding unit. It may be supplied by dropping.

  According to the above configuration, of the plurality of sheet bundles arranged in the stocker, one of the sheet bundles that has moved to the vicinity of the edge of the stocker deviates from the stocker, and the sheet bundle is moved to the holding unit. be able to. If the drop supply is based on natural fall, no power is required. It should be noted that the sheet bundle can be prevented from being damaged by performing a natural fall of a slight step instead of a large drop. Further, if the device is dropped under the action of the pressing force of the pressing portion, the falling speed becomes extremely slow, and the impact due to the natural drop can be reduced.

  Further, in each of the inventions relating to the intermittent sheet member supply device described above, the pushing section is provided so as to be able to advance and retreat from the outside of the one bundle of sheets held by the holding section toward the generatrix direction. The sheet bundle can be moved in the generatrix direction by extruding the sheet bundle from the edge in the generatrix direction.

  According to the above configuration, by operating the push-out portion that can move forward and backward, it is possible to move the sheet bundle in the generatrix direction while abutting on the generatrix end edge of the sheet bundle at the time of advance, and the sheet bundle separates the individual sheet members. It is possible to move (slide) as a unit without performing the operation. At this time, the extruded portion (abutting surface) of the extruded portion is brought into contact with the end edges of all the sheet members constituting the sheet bundle at the same time, thereby ensuring the integrity of the sheet bundle.

  In the invention according to the sheet member intermittent supply device having the above-described configuration, the holding section has a gap formed between the holding section and the stocker, and the pushing section further includes the pushing section, which is provided from the outside of the sheet bundle. The sheet bundle may be provided with a contact area that can contact the edge in the generatrix direction of the sheet bundle in a range reaching the gap.

  In the case of such a configuration, the gap formed between the holding unit and the stocker is near the bent portion of the sheet bundle held by the holding unit. It will come into contact with the terminal edge near the part. When the pushing section pushes out the sheet bundle at such a contact position, the sheet bundle is pushed out below the center of gravity, and the posture is stabilized. In addition, since a plurality of stacked sheet members are concentrated in the vicinity of the bent portion of the sheet bundle, the sheet members have appropriate strength against the action of external force, and reduce the possibility of deformation or breakage due to the pushing force. Can be.

  In the invention relating to the sheet member intermittent supply device according to each of the above-described configurations, in addition to these configurations, the configuration further includes a detection unit that detects a position of a bent portion of the sheet bundle held by the holding unit. Is also good.

  According to the above configuration, it is possible to determine whether or not the holding state of the sheet bundle by the holding unit is normal by detecting the position of the bent portion. By inputting the detection result of the detection means to the control device and judging its suitability, it is possible to automate the intermittent supply. Note that the detection unit can be configured by an imaging unit for acquiring an image and an analysis unit for analyzing the state of the sheet bundle from the acquired image. As an analysis method in this case, an internal space formed in the bent portion of the sheet bundle can be detected from the image. The inner space of the sheet bundle is a space in which the sheet member does not exist inside the innermost layer of the area where the bent portion of the sheet member is curved, and this portion is detected as the space.

  On the other hand, the present invention according to the sheet member unfolding device is interlocked with an intermittent supply device by moving a sheet bundle formed by a plurality of folded sheet members in the generatrix direction of the bent portion of the sheet bundle. An apparatus for unfolding the sheet bundle, comprising: a widening member provided in front of the sheet bundle in the moving direction and having a sharp end disposed near the center of the bent portion of the sheet bundle. It is a feature.

  According to the above configuration, since the widening member having the tip is disposed in front of the direction in which the sheet bundle moves, the tip enters the center of the bent portion of the sheet bundle as the sheet bundle moves, and The movement of the sheet bundle makes it possible to develop the folded sheet bundle. Since the cross section of the folded portion of the folded sheet bundle is substantially circular or elliptical, the bent portion of the sheet member located at the innermost layer has a slightly hollow portion. The widening is made possible by making the point penetrate. That is, the hollow portion as described above is formed at the center of the bent portion of the sheet bundle, and the pointed tip is disposed in front of the sheet bundle moving direction toward the vicinity of the center of the hollow portion (the center of the bent portion). By doing so, it becomes possible to make the point enter the hollow portion.

  In the invention according to the sheet member expanding device having the above-described configuration, the widening member includes a pointed tip formed in a pointed shape in both a plan view and a side view, and a widened portion that is widened at least in a plan view. It can be.

  In the case of the above configuration, the point can be made to enter the inside of the sheet bundle from the vicinity of the center of the bent portion, and after this entry, the sheet bundle is spread in the left-right direction as the sheet bundle moves. Thus, the form is changed from the folded state to the developing direction. Note that the widening portion may have a shape that is widened in a side view. In this case, the widening member enters between corresponding surfaces of the sheet member located at the innermost layer of the sheet bundle, and a gap between both members is formed. It will work to expand.

  In the invention relating to the sheet member unfolding device of each of the above configurations, it is possible to further include a conveyor belt provided below the widening member at an appropriate distance from the widening member.

  In the case of the above configuration, the moving sheet bundle is initially moved by the supply device, and the movement can be continued by the conveyor belt even when the sheet bundle is appropriately unfolded. In addition, the conveyor belt does not need to be disposed immediately below the widening member, but may be provided at a position where the unfolded sheet bundle is placed, and is mounted on the surface of the conveyor belt by its own weight. It is transported in an unfolded state.

  In the invention according to the sheet member expanding device having the above-described configuration, the apparatus further includes a collection unit for separating a sheet bundle with poor expansion from being conveyed to a subsequent process in front of the sheet bundle conveyed by the conveyor belt. can do.

  According to the above configuration, if the spread of the sheet bundle by the widening member becomes insufficient, or if the spread position is asymmetric in the left-right direction, it causes a problem when moving to a subsequent process. For this reason, it is possible to provide a collecting means and to separate from the normal conveyance. As a collecting means, there is a method of dropping below the position of the conveyor belt, and in this case, there is a method of using a second conveyor belt that changes the direction of conveyance in the end of the conveyor belt.

  In the invention relating to the sheet member expanding device according to each of the above-described configurations, the sheet member expanding device may further include a detection unit that detects a state of the sheet bundle expanded by the widening member.

  According to the above configuration, by detecting the state of expansion by the widening member and the state of the sheet bundle after expansion, it is possible to quickly remove a sheet bundle with poor expansion or to deviate from the transport path. For detecting the state of the sheet bundle, there is a method in which an image is analyzed and a determination is made based on whether or not a sheet bundle developed at a predetermined position exists. In this case, it is configured by the photographing means for acquiring the image and the analyzing means for analyzing the developed state of the sheet bundle from the acquired image, but it is possible to easily determine by fixed point observation. Become.

  ADVANTAGE OF THE INVENTION According to this invention which concerns on the intermittent supply apparatus of a sheet member, the sheet bundle formed by laminating | stacking several sheet members turns down the bending part folded for two-fold in the state folded in half. In this manner, a large number of sheet bundles to be aligned are sequentially moved to the holding unit one by one, and are extruded in the direction of the generatrix of the bent portion at the holding unit, thereby intermittently making one bundle at a time. Can be supplied to In a configuration in which the holding unit is disposed below the stocker, relocation by natural fall from the stocker becomes possible, and when a gap is formed between the holding unit and the stocker, the pushing unit is moved to the gap. , And the sheet bundle can be easily and reliably extruded.

  On the other hand, according to the present invention relating to the sheet member unfolding device, the intermittent supply device of the sheet bundle causes the widening member to unfold the sheet member as the sheet bundle moves in the generatrix direction of the bent portion. As a result, the width of the two pieces folded in two can be expanded, and the two pieces can be developed in conjunction with intermittent supply. In the configuration in which the conveyor belt is provided, the sheet bundle after the development can be conveyed to the next step depending on the state of being placed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, an embodiment of the intermittent sheet member supply device will be described, and then, an embodiment of the intermittent sheet member supply device will be described.

  FIG. 1 is a diagram schematically illustrating an embodiment of an intermittent sheet member supply device. As shown in this figure, the present embodiment includes a stocker 1 having an appropriate capacity, and two partition plates 2 and 3 supported above the stocker 1. The holding portion 4 is formed, and has a pushing means 5 outside thereof.

  The stocker 1 includes a bottom portion 11 having an appropriate area and side portions 12 and 13 having an appropriate height in the front-rear direction, so that a plurality of sheet bundles can be placed on the bottom portion 11. The edges of the placed sheet bundle in the front-rear direction can be arranged by the side portions 12 and 13.

  The partition plates 2 and 3 are supported by sliders 22 and 32 slidable on slide shafts 21 and 31 disposed above the stocker 1, and can abut the flat portion of the sheet bundle in an appropriate range. It is composed of a plate member having an area. The slide shafts 21 and 31 are oriented in the longitudinal direction in the direction in which the sheet bundle should be moved, and guide the sliders 22 and 32 to slide in the axial direction (the direction in which the sheet bundle should be moved). The sliding of the sliders 22 and 32 is controlled by an actuator (not shown).

  When the first slider 22 is stopped, a driving force is transmitted to the second slider 32 in the moving direction, so that a pressing force can be applied. Therefore, the second partition plate 3 supported by the second slider 32 functions as a pressing portion.

  The pressing by the second partition plate 3 allows a plurality of sheet bundles (a bundle of sheet bundles) to be sandwiched between the first partition plate 2 and the two partition plates 2 and 2 simultaneously in the sandwiched state. By moving 3, the lump can be moved collectively. Further, by bringing the two partition plates 2 and 3 close to each other, it is possible to pinch one bundle of sheets.

  When the sheet bundle is not moved, the first partition plate 2 is stopped above the end edge of the holding unit 4 so as to function as the wall surface of the holding unit 4. By moving the second partition plate (pressing portion) 3 with respect to the first partition plate 2 to gradually reduce the interval between the first partition plate 2 and the sheet bundle to be intermittently supplied. Are sequentially moved.

  The holding section 4 is provided at a position deviating from the bottom section 11 of the stocker 1. In the present embodiment, it is formed in a gutter shape having a substantially V-shaped cross-section, and as a whole, is formed below the bottom surface 11 near the edge of the bottom surface 11 of the stocker 1. Therefore, in the V-shaped gutter, two inclined surfaces 41 and 42 are arranged to face each other, and the center is the lowest bottom 43. In addition, a vertical surface 44 is formed on the inclined surface that is continuous with the stocker 1, and a side wall 45 is formed on the opposite side with an appropriate thickness between the inclined surface 42 and the inclined surface 42. Note that the interval between the wide portions (the interval between the upper ends of the inclined surfaces 41 and 42) of the holding unit 4 is set to one bundle of sheet bundles, and the holding unit 4 can hold only one bundle of sheet bundles. . As described above, the holding unit 4 that can hold only one bundle of sheets is provided below the bottom part 11 of the stocker 1, so that one bundle of sheets exceeds the bottom part 11. When moving to the holding section 4, the user can drop the sheet onto the holding section 4.

  The pushing means 5 includes a pushing portion 51 that can be inserted slightly upward from the outside of the holding portion 4, and a first rail 52 and a second rail 53 that control the moving direction of the pushing portion 51. Configuration. The base of the pushing section 51 is slidably contacted with the first rail 52, and the base slides along the rail 52, thereby enabling movement in the pushing direction. The first rail 52 is supported by the second rail 53, and its base is slidable along the second rail 53 by being in sliding contact with the second rail 53. Has become. Each of these slides is driven by an actuator (not shown), and the sliding direction of both rails 52 and 53 is orthogonal, and the direction of one (first rail 52) is the X-axis direction. In this case, the position of the pushing section 51 can be controlled with the direction of the other (second rail 53) as the Y-axis direction.

  The sheet bundle to be intermittently supplied is, for example, a laver bundle. As shown in FIG. 2, a normal laver bundle is a fishery or aquaculture company, in which a plurality of laver sheets processed into a sheet shape are laminated to form a bundle, and further, this is folded in two in a state P1 to P10. Further, a plurality of bundles are overlapped to form a block P0. In this state, it is delivered to the processor in a state of being bound by the paper (band) R. The processor removes the knot R1 of the band seal R and puts the folded seaweed bundles P1 to P10 into a baking processing device or the like in units of units. The processing trader here is a trader of grilled laver processing.

  As described above, the folded sheet bundles P1 to P10 cannot be put into the processing apparatus as they are, and the folded state is developed (the bent portion Q is flattened). As a result, a flat laver sheet is laminated. Until now, because of the difficulty in automation, it has been developed manually and supplied to the input section of the processing equipment.

  In the present embodiment, the sheet bundles P1 to P10 are intermittently supplied in the state of being folded in two as described above. Therefore, the stocker 1 of the present embodiment is based on the premise that the sheet bundles P1 to P10 are aligned with the bent portions Q facing downward. Therefore, the operation state of the present embodiment will be described below while showing the moving state of the sheet bundles P1 to P10.

  As shown in FIG. 3, the plurality of sheet bundles P <b> 1 to P <b> 10 are all placed on the bottom surface 11 of the stocker 1 with the bent portions Q facing downward. At this time, the above state is maintained by sandwiching both sides of the plurality of sheet bundles P1 to P10 between the two partition plates 2 and 3. In this state, by moving the two partition plates 2 and 3 simultaneously (sliding the sliders 22 and 32), the partition plates 2 and 3 can be moved while maintaining the state in which all the sheet bundles P1 to P10 are sandwiched. Note that the first partition plate 2 can be moved to a position where the first partition plate 2 has passed through the holding unit 4.

  FIG. 4 shows a state in which the whole is moved in this way. As shown in this figure, the first partition plate 2 is disposed immediately above the side wall 45 of the holding portion 4 with a gap. By stopping the first partition plate 2 at this position, it functions as the wall surface at the end (end) of the stocker 1. In this state, the second partition plate 3 is pressed in the direction of the first partition plate 3 and functions as a pressing portion. The pressing direction is orthogonal to the generatrix direction of the bent portion Q formed by bending the sheet bundles P1 to P10. Note that the generatrix direction means the generatrix of the column because the shape of the bent portion Q is substantially cylindrical. In other words, the pressing direction is the same as the stacking direction of the plurality of sheet bundles P1 to P10.

  As described above, the state in which the sheet bundles P1 to P10 are arranged, that is, the first partition plate 2 is located above the side wall of the holding unit 4, and presses the sheet bundles P1 to P10 toward the partition plate 4. In such a state, the sheet bundle P1 for one bundle located at the forefront can be moved to above the holding unit 4. By naturally dropping the frontmost sheet bundle P1, the sheet bundle P1 for the one bundle can be supplied to the holding unit 4. This state is shown in FIG.

  As shown in FIG. 5, the sheet bundle P <b> 1 supplied to the holding unit 4 naturally has the bent portion Q facing downward, and two generatrixes of the curved surface (cylindrical curved surface) are V-shaped gutter portions. Abut each other on both inclined surfaces 41 and 42. Details at this time are shown in FIG.

  That is, as shown in FIG. 6A, the cross-sectional shape of the outermost layer of the bent portion Q is substantially circular or substantially elliptical, or a curve similar thereto (this may be referred to as a curve near a circle). It is a state having. When two opposed inclined surfaces 41 and 42 come into contact with such a curve near the circle, each comes into contact only at each one point. Further, when the two inclined surfaces 41 and 42 facing each other have the same inclination angle, the contact points of the curve near the circular shape have the same height on both sides of the lowermost end, and the weight is equally distributed between both contact points. It is supported in the state where it was done. As described above, the sheet bundle P1 in a state where the sheet bundle P1 is uniformly supported on both sides of the lowermost end of the bent portion Q, is held in a vertically upright posture with the bent portion Q facing down. . Accordingly, the sheet bundle P1 is supplied to the holding unit 4 in the same posture as the posture of the sheet bundle P1 placed on the bottom surface portion 11 of the stocker 1.

  As described above, when one sheet bundle P1 is supplied to the holding unit 4 by natural fall, the bent portion Q of the sheet bundle P1 is located below the lower end edge of the first partition plate 2. Then, the gap H between the side wall 45 of the holding unit 4 and the first partition plate 2 is closed by the flat portion S of the supplied sheet bundle P1. This means that the sheet bundle P1 exists inside the holding unit 4 from the gap H.

  Therefore, as shown in FIG. 6B, at a height at which a part (projection piece 51 a) of the pushing portion 51 of the pushing means 5 can be inserted from the gap H into the inside of the holding portion 4, The sheet bundle P1 can be moved in the direction of the generatrix by abutting the edge and pushing the sheet bundle P in the direction of the generatrix of the bent portion Q.

  FIG. 7 shows a state in which the sheet bundle P1 is moved in the generatrix direction of the bent portion Q. As shown in this drawing, the protruding piece 51a of the push-out section 51 is kept in contact with the rear edge (end edge) of the sheet bundle P1 in the generatrix direction, and is pushed out to thereby form the sheet bundle P1. Can be moved. Since the moving direction is parallel to the plane portion of the adjacent sheet bundle P2 and parallel to the surface of the first partition plate 2, it can be moved without any trouble. Although frictional resistance between the holding unit 4 and frictional resistance between the adjacent sheet bundle P2 and the two surfaces of the partition plate 2 is generated, they can be moved by applying a pushing force against them. . The movement of the push-out section 51 at this time is in the direction along the first rail 52.

  If such a state is shown in plan view, the state shown in FIG. 8 is obtained. FIG. 8A shows a state before the movement is started, and FIG. 8B shows a state during the movement. It should be noted that the boundaries between the two pieces of the folded sheet bundles P1 to P10 are omitted from the drawing. As shown in this figure, it is preferable that the leading end of the protruding piece 51a of the extruding portion 51 does not reach the adjacent sheet bundle P2, and it is preferable that the tip abuts on the entire edge of the sheet bundle P1 to be moved. .

  According to the above-described procedure, the individual sheet bundles P1 to P10 can be sequentially moved outward one by one from the stocker 1, and intermittent supply is possible while maintaining the folded state. is there.

  After the first sheet bundle P1 is moved (intermittently supplied), as shown in FIG. 9A, a gap corresponding to one bundle is generated. Since the second partition plate 3 functions as a pressing portion, the entire sheet is pressed from the side of the sheet bundle P10 in the final order, and immediately after the gap is generated, as shown in FIG. The sheet bundles P2 to P10 are moved to the first partition plate 2, and then the next-order sheet bundle P2 is supplied to the holding unit 4 by natural fall. At this time, since the protruding piece 51a of the extruded portion 51 is located above the holding portion 4, when the extruded portion 51 is retracted, the protruding piece 51a is moved laterally along the second rail 53, and the protruding piece 51a is moved. That is, the vehicle can be moved backward beyond the holding portion 4. Thus, even after the next sheet bundle P2 is supplied to the holding unit 4, the pushing unit 51 can be moved backward. After the pushing part 51 is retracted, the protruding piece 51a is moved again to a position above the holding part 4, and the pushing is repeated.

  Although the present embodiment is as described above, other configurations can be added to them. For example, as shown in FIG. 5, a camera CA1 for acquiring an image from outside the holding unit 4 can be installed toward the bent portion Q of the sheet bundle P1 to be supplied. The image captured by the camera CA1 is the rear end of the sheet bundle P1, and is in a state as shown in FIG. Therefore, in the state as shown in FIG. 6A, the central region of the bent portion Q (the circular shape in the innermost layer) is obtained from the image of the rear end of one bundle of sheets P1 supplied to the holding portion 4. It is also possible to detect a region Q0 indicating a recent shape). The detection of the central area Q0 can be used to determine whether the supply state of the sheet bundle P1 to the holding unit 4 is good or not, and the information is input to the control device. By setting a threshold value of whether or not it has been detected, it is possible to determine whether the detection is appropriate. If the sheet is fed to a defective position in accordance with the propriety determined by the control device, if the sheet bundle is removed, the propriety determination can be automated.

  As shown in FIG. 5, an image is also acquired from above by the camera CA2 for the sheet bundle P1 to be supplied intermittently. This is provided to detect the state of the posture during supply (movement by the pushing unit 51). These two cameras CA1 and CA2 acquire images from different directions with respect to the sheet bundle P1.

  That is, as shown in FIG. 10A, the moving direction of the stocker P1 to be supplied by the stocker is the X-axis direction, the direction to be supplied (moved) is the Y-axis direction, and the vertically downward direction is the Z-axis direction. As for the direction, the first camera CA1 is installed toward the Y-axis direction, and the second camera CA2 is installed toward the Z-axis direction. Then, as shown in FIG. 10B, the first camera CA1 captures the periphery of the bent portion Q and detects the position of the center region Q0 of the bent portion Q. As shown in FIG. 10C, the camera CA2 captures an image from above the sheet bundle P1 to be supplied, and detects the height of the edge.

  The detection of the central region Q0 by the first camera CA1 is as described above, and the detection of the attitude of the sheet bundle P1 by the second camera CA2 can be performed by the following method. That is, the sheet bundle P <b> 1 to be supplied (moved) is pushed out by the pushing unit 51 in the vicinity of the bent portion Q. At this time, when the sheet bundle P1 is normally supplied (moved), the upper end edge of the sheet bundle P1 is substantially horizontal as shown in FIG. In this case, as shown in FIG. 11B, the front is in a floating state. The reason for such a poor posture state is that the sheet is in surface contact with the next sheet bundle P2, so that the frictional resistance is excessively large, For example, a case where a strong pushing force acts may be considered. Since the sheet bundle P1 to be supplied slides along the holding portion 4 (FIG. 4), it is difficult to assume that either the front end or the rear end of the moving sheet bundle P1 floats up and a defective state is assumed. .

  Therefore, the height of the upper edge of the sheet bundle P1 is detected by the second camera CA2, and the quality of the posture is determined based on the detection result. That is, the second camera CA2 is a depth camera that detects the depth, and plots the depth at a plurality of points on the upper edge of the sheet bundle P1 and analyzes the numerical values.

  This analysis method will be described with reference to FIG. For example, as shown in FIG. 12A, a case is assumed where the front end in the traveling direction is greatly raised. The image from the upper edge side at this time is as shown in FIG. In addition, since the sheet bundle P1 is formed by stacking a plurality of sheet members, strictly, an image related to an aggregate of the edges of the individual sheet members is obtained. With respect to the position of the edge, a plurality of depths (values in the Z-axis direction) obtained by averaging a plurality of points in a minute range △ x in the X-axis direction are plotted in the Y-axis direction and converted into YZ coordinates. . By connecting these points with straight lines, two types of straight lines L1 and L2 are obtained. These two straight lines can be represented by L1: Z = a1Y + b1 and L2: Z = a2Y + b2, respectively (however, a1, a2, b1, and b2 are straight line parameters). Therefore, the direction (posture angle to θ) of the long side (L2 in the figure) of the two straight lines is calculated. Θ at this time indicates the degree to which the front end of the sheet bundle P1 is consequently lifted. In the case of the above example, | tanθ | = | a2 |.

  Therefore, when judging whether the posture of the sheet bundle P1 is good or bad, a threshold value is set in advance for the magnitude of θ, and if the value is less than the threshold value, the posture is judged to be good. Can be determined to be in a good state. In setting this threshold value, it is possible to use the angle (θ) as a large value as a guideline when a problem occurs in the next process at the supply destination (for example, the developing device). If the front end does not rise, there is only one straight line, which is determined by the inclination angle (θ) of the single straight line. Will be done. If the degree of lifting is small or the edge is not a uniform straight edge from the beginning, these are processed as an error so that the number of straight lines becomes one, and the straight line is similarly not inclined (θ = 0). ).

  The above processing can be performed by the control device to determine whether the posture of the sheet bundle P1 is good or not, and when a state where the posture is poor is detected, a means for notifying the state is provided. Is also possible. If the posture of the sheet bundle P1 is not good, the sheet bundle P1 is removed from the supply device by a manual operation or the like in order to stop the conveyance to the next process.

  Next, an embodiment according to the sheet member expanding device will be described. FIG. 13 shows an outline of the configuration of the developing device. FIG. 13A is a perspective view of a widening member used in the developing device, FIG. 13B is a plan view, and FIG. 13C shows a state around the widening member in a side view.

  As shown in FIG. 13A, the widening member 6 has a pointed end 61, and forms a widened portion 63 whose diameter is entirely increased from the pointed end 61 toward the main body 62. Here, the widened portion 63 is bilaterally symmetric in plan view, and is configured to gradually increase at least the width dimension (see FIG. 13B). Since the width is symmetrical and the width is gradually enlarged, it is possible to expand the sheet bundle folded in two so that two pieces on both sides are pushed and spread.

  In the present embodiment, the height dimension is also gradually increased (see FIG. 13C). This is because, as shown in the drawing, since the point 61 is arranged at a lower position, the sheet bundle started to be expanded by the point 61 is also subjected to the above-described state of expansion. In the present embodiment, as an example, the position of the point 61 is lowered to the height of the bottom surface 67 of the widening member 6. Since it is assumed that the sheet bundle to be unfolded is supplied with the folded portion in the folded state facing downward, the unfolding is to start the unfolding from the pointed end. As a result, the widened portion 63 of the present embodiment has a shape in which a conical shape as a whole is turned sideways, and a bottom surface 67 is formed by cutting the lower side from the position of the point 61.

  A flat portion 60 is formed on the upper portion of the main body portion 62 of the widening member 6, and connection holes 60 a, 60 b, 60 c, and 60 d in which female screws are formed in the flat portion 60 are provided. As shown in FIG. 13C, the connection holes 60a to 60d are used for screwing bolts 64, 65 for supporting the widening member 6 from above, and the bolts 64, 65 are connected to the upper frame of the deployment device. It is fixed in a state of hanging from 66. The deploying member 6 supported by the upper frame 66 via the bolts 64 and 65 has its bottom surface 67 installed with a gap from the base 68 of the deploying device. By forming the gap in this manner, the sheet bundle can pass through the gap.

  The sheet bundle to be developed is sent from the right side to the left side in the figure, and a conveyor belt 69 is disposed below the widening member 6. The sheet bundle to be transferred onto the conveyor belt 69 is further moved to the left. To be transported to Further, by installing a camera CA3 for acquiring an image above the widening member 6, it is also possible to acquire an image of a sheet bundle in a developed state. The image acquired here is for judging the appropriateness of the state of the developed sheet bundle, and when there is a problem in a subsequent process such as when the image is unbalanced to the left or right, the image of the image is acquired. Judging from the state, it is possible to collect a sheet bundle that has been badly developed.

  Since the unfolding device of the present embodiment has the above-described configuration, as shown in FIG. 14, the sheet bundle P in a state where the bent portion Q is directed downward is moved from the outer side of the pointed end 61 of the widening member 6. As a result, the point 61 enters the central region Q0 of the bent portion Q, is pushed and spread in the left-right direction by the widened portion 63 of the widened member 6, is gradually expanded, and finally is expanded to a flat state. It becomes.

  That is, as shown in FIG. 14A, the center line of the widening member 6 having a symmetrical shape is made coincident with the direction in which the sheet bundle P is supplied (moved), and the position of the tip 61 is determined. It is adjusted to be inside the central region Q0 of the bent portion Q formed in P. The generatrix of the bent portion Q of the supplied sheet bundle P is maintained parallel to the center line of the widening member 6, and the feeding direction is the generatrix direction. Since the widening member 6 is fixed, the central region Q0 of the bent portion Q can be made closer to the point 61 by moving the sheet bundle P. Note that the movement of the sheet bundle P at this time can be performed by extrusion by the extrusion unit 51 in the above-described intermittent supply device.

  When the sheet bundle P moves in the generatrix direction of the bent portion Q, the tip 61 enters the central region Q0 of the bent portion Q, as shown in FIG. Due to the (wide) structure, the two pieces Pa and Pb that are folded in half are pushed right and left. At this time, the widening portion 63 applies a widening force to the sheet bundle P around the bent portion Q, and the bottom surface 67 of the widening member is moved so that the sheet bundle P does not move in a direction deviating from the widening member 6. The bent portion Q of the sheet bundle P is gently held by the gap between the sheet bundle P and the platform 68 of the developing device. Due to this sandwiching state, the bent portion Q moves in a state where it is regulated in the moving direction. In addition, since the widened portion 63 is also gradually increased in height, the widened portion 63 does not enter the central region Q0 of the bent portion Q and tilts the two pieces Pa and Pb left and right. be able to.

  By further moving the unfolded sheet bundle P, the left and right pieces Pa and Pb of the sheet bundle P are tilted laterally to both sides as shown in FIG. The whole P is in a developed state. At this time, since the sheet bundle P has been sufficiently moved, the sheet bundle P is already mounted on the conveyor belts 69a and 69b, and thereafter is conveyed by the conveyor belts 69a and 69b.

  Although the illustrated conveyor belts 69a and 69b are arranged below both sides of the widening member 6, they may be arranged immediately below, or a wide belt including both left and right sides and immediately below may be used. When a wide belt is used, at the time when the sheet bundle P is supplied to the widening member 6, at least the bent portion Q is guided by the conveyor belt in the conveying direction (the direction in which the sheet bundle is developed), and the development of the sheet bundle P proceeds. As a result, the left and right pieces Pa and Pb are placed on the surface of the conveyor belt and moved as a whole in the transport direction.

  Further, in the above configuration, based on an image acquired by the camera CA3 installed above the widening member 6, when the state of the unfolding of the sheet bundle P is defective, the collection method is as follows. There is a way to deviate from the route. For example, as shown in FIG. 15, a configuration may be adopted in which a rejected product collection unit 7 is provided in the sheet bundle conveyance direction by the conveyor belt 69. The collection means 7 is constituted by a conveyor belt provided rotatably with the upstream side of the conveyance path as a fulcrum. Passed products are conveyed as they are, but rejected products are conveyed at the free end. It rotates downward and sends it out to the lower collecting section 70. For the determination of the rejected product, the above-described processing using the image can be performed.

  As described above, since the unfolding operation is enabled by moving the sheet bundle P with respect to the fixedly supported widening member 6, the intermittent power is used as the power for moving the sheet bundle P. If the movement by the supply device is used, it can be a deployment device linked to the intermittent supply device. FIG. 16 shows the entire state in this case. As shown in this figure, the plurality of sheet bundles P1 to P10 aligned on the stocker 1 are sequentially moved toward the developing device B by the pushing means 5 of the intermittent supply device A, and in the course of the movement. In this case, the sheet is unfolded by the widening member 6 of the unfolding device.

    Here, a flow when each device is automated (systemized) will be described. FIG. 17 shows a processing flow in the stocker 1, FIG. 18 shows a processing flow of the pushing means 5, and FIG. 19 shows a processing flow for collecting a defectively developed sheet bundle P in the developing device. When these are linked, all of them are started at the same time, but individual devices may be operated individually.

  First, the processing flow of the system in the stocker will be described with reference to FIG. When the control of the stocker is started, the partition plate moves to the initial position, and the operation is controlled based on the initial position (S101). Then, in order to hold a predetermined number of sheet bundles (lumps of sheet bundles) by the partition plate of the stocker, the sheet bundle is moved to its receiving position (S102). Here, the lump of the sheet bundle can be moved to the stocker by the supply conveyor (conveying cart). At the time of the transfer, the partition plate is moved to the outside of the stocker, the mass of the sheet bundle is moved by the supply conveyor to the middle of the partition plate greatly widened on both sides, and then the partition plate is approached from both sides. Thereby, both sides of the lump can be clamped by the partition plate. In this state, the setting of the mass of the sheet bundle is completed (S103). By simultaneously moving the partition plates on both sides in this sandwiching state, the surface of the supply conveyor can be moved and further reach the surface of the stocker while maintaining the sandwiching state (S104). When the end point of this movement moves the first sheet bundle to the holding unit, the supply (drop) of the first sheet bundle to the holding is completed.

  Subsequently, the position of the central region (Q0) of the bent portion of the sheet bundle supplied (dropped) to the holding portion is determined (S105), and if normal, the pressing portion is operated (S106). After confirming the existence of the sheet bundle to be continuously supplied (S107), the movement of one sheet bundle (pressing by the pressing unit) is performed (S108), and the position of the central region (Q0) of the sheet bundle is performed. It repeats similarly from judgment of. If the position of the central area (Q0) is abnormal, an error is immediately notified (S109), and in this case, the sheet bundle is manually removed. When removing the sheet bundle, the apparatus is temporarily stopped at the same time as the error warning in consideration of safety.

  Next, the processing flow of the pushing means will be described with reference to FIG. The pushing unit is in a standby state until the pushing unit is operated, but when the process is started, the pushing unit is moved to the initial position as a waiting state (S201). Here, when there is an operation command for starting the movement in the above-described control of the stocker (S202), the subsequent processing starts. Upon receiving the movement command, the extruding section is advanced (S203). This advance is extrusion for feeding (moving) the sheet bundle, and moves in the Y-axis direction along the first rail of the extrusion unit. The movement of the push-out unit is stopped at the time when the push-out unit is advanced to the predetermined position (S205). During the movement, the posture of the sheet bundle is checked (S204).

  When the posture of the sheet bundle is normal, the forward movement of the pushing unit is continued as it is and is continued until it stops (S205). However, when an abnormality is detected in the posture of the sheet bundle, an error is notified and (S206) The movement stops (S207). In a state where the pushing section is stopped, the sheet bundle in the bad posture is manually removed. After the removal, the processing is restarted, and the extruding unit advances to the expected final position and stops (S205).

  Regardless of whether the posture of the sheet bundle is normal or abnormal, the pushing section is stopped at the scheduled end point (S205), and then separated from the holding section (moved in the X-axis direction) (S209). Is retracted (moved in the Y-axis direction) (S210), and further moved toward the holding unit (in the X-axis direction) to return to the initial position (S211). The movement in the X-axis direction is movement along the second rail. The movement in the positive direction moves away from the holding unit, and the movement in the negative direction returns. Further, the movement in the Y-axis direction is movement along the first rail, and moves forward by moving in the positive direction and retreats by moving in the negative direction.

  By these processes, the extruding unit waits at the initial position, but if there is a sheet bundle to be continuously supplied, it waits for a movement command in the standby state, and if there is no sheet bundle to be supplied, The process ends. In this way, by interlocking the processing of the stocker and the processing of the pushing means, intermittent systematization of the sheet bundle is realized.

  Next, a process of removing a sheet bundle having a deployment failure in the deployment device will be described with reference to FIG. The operation of expanding the sheet bundle in the developing device is performed by supplying the sheet bundle to the fixed widening member as described above. Therefore, the supply mechanism for the widening member is not described here. The supply mechanism can be configured by intermittently supplying the sheet bundle by the above-described intermittent supply device. However, the sheet bundle may be supplied by another supply device. May be supplied.

  In any case, when the processing is started, the conveyor belt of the developing device starts (S301). At the same time, the development state of the sheet bundle that has passed through the widening member is acquired (S302), and its suitability is determined (S303). If the developed state is normal, the sheet is conveyed by the conveyor belt as it is, and if there is a continuous sheet bundle, the above is repeated (S304).

  On the other hand, when a failure is detected in the spread state of the sheet bundle, the sheet bundle is forcibly discharged (S305). When the discharge (recovery) method at this time is to discharge to a different transport path depending on the discharge conveyor belt as described above, the conveyor belt is operated (S205), and the conveyor belt is returned after the discharge (S206). ).

  As described above, the system control of the operation of the stocker and the operation of the extruding means makes it possible to automate the intermittent supply of the sheet bundle, and to provide the developing device so as to interlock with the movement during the intermittent supply. This makes it possible to consistently automate the operation from the supply of the mass of the sheet bundle to the developing operation. Further, by detecting the developing state of the developing device and controlling the elimination process by the system, it is also possible to automate the transfer of only the normally developed sheet bundle to the next process device.

  Although the embodiment of the present invention is as described above, the above embodiment is an example, and the present invention is not limited to the above embodiment. Therefore, it is possible to appropriately modify the components of the above-described embodiment, and to add other components. For example, as shown in FIG. 20, one extrusion means 5 is provided, and stockers 1A and 1B are arranged symmetrically on both sides thereof, so that two rows of intermittent supply are alternately provided by one extrusion means 5. It can be carried out. In this case, it is possible to construct a transport path for the sheet bundles developed in two rows by arranging the carrier developing device also at the supply destination. In this case, the push-out portion 51 can be moved forward and backward by two-dimensional control of the X axis and the Y axis by using the first and second rails.

  Furthermore, the shape of the holding portion 4 is not limited to the V shape, and may be a substantially U shape as shown in FIG. Further, the holding portion 4 does not need to be formed continuously with the stocker 1, but may be separated from the edge of the stocker 1 and may be formed with an appropriate interval as shown in FIG. . In this case, the tip of the protruding piece 51a of the extruded portion 51 can reach the gap between the two, and it becomes easy to apply a pushing force to all the sheet members forming the sheet bundle P, Can be reliably pushed out.
