1 shows a plan view of a flat plate work.

The planar view shape of the plate work 1 is not particularly limited, and examples thereof include substantially rectangular shape (approximately rectangular shape is substantially rectangular shape or substantially square shape), approximately polygonal shape such as approximately triangular shape, approximately hexagonal shape, and approximately circular shape. A shape, a substantially elliptical shape, a different shape in which these shapes are combined, and the like are enumerated. "Approximately" in the above-mentioned substantially rectangular shape, substantially triangular shape, and substantially polygonal shape includes, for example, a shape in which the corners are chamfered, a shape in which some of the sides are slightly raised or recessed, a shape in which the sides are slightly curved, and the like. In addition, "approximately" of the above substantially circular shape and substantially elliptical shape includes, for example, a shape in which a part of the circumference slightly rises or sinks, a shape in which a part of the circumference is slightly straight or oblique, and the like.

1 shows a flat plate work having a substantially rectangular shape in plan view. The approximate rectangle is a plan view shape having a long side (a side along the major axis) and a short side (a side along the minor axis). In addition, although Fig. 1 shows a substantially rectangular flat plate work in which four rectangular corner portions are chamfered, the corner portions may be at right angles.

Reputation work is obtained from any web.

The type of the flat plate work (and the web underlying the flat plate work) is not particularly limited, and any synthetic resin film, any plastic plate, any thin metal plate, and a laminated plate in which two or more types of arbitrary layers are laminated, etc. are listed For example, in the present invention, a flat plate work containing an optical film (and a web containing an optical film) is used. The flat plate work containing an optical film may be comprised only of an optical film, and may have components other than an optical film and an optical film.

FIG. 2 is one structural example of a flat plate work containing an optical film, and FIG. 3 is another structural example of a flat plate work containing an optical film.

Referring to FIG. 2, the flat work 1 is an optical film 11, a separator film 13, and an adhesive interposed between the optical film 11 and the separator film 13 to adhere both films 11 and 13. It has a layer (12). The pressure-sensitive adhesive layer 12 is strongly adhered to the optical film 11 and adhered to the separator film 13 so that peeling is possible. The separator film 13 may be peeled at the interface with the pressure-sensitive adhesive layer 12 . In the case of use of the flat work 1, it peels and removes the separator film 13 normally. In addition, the flat plate work 1 does not have to have the said adhesive layer 12 and the separator film 13.

The optical film 11 includes an optical function film. Examples of the optical functional film include a polarizer, a retardation film, a light diffusion film, a luminance enhancing film, an antiglare film, and a light reflecting film. A polarizer is a film having a property of transmitting light (polarized light) vibrating in one specific direction and blocking light vibrating in other directions. The retardation film is a film exhibiting optical anisotropy, and representative examples thereof include stretched films such as acrylic resins, cycloolefin resins, and cellulose resins. Moreover, the optical film 11 may contain the protective film. A protective film is laminated for the purpose of protecting the optical function film. As the protective film, a colorless and transparent film is typically used.

The optical film 11 of the flat work 1 illustrated in FIG. 2 has the 1st protective film 111, the polarizer 112, and the 2nd protective film 113 sequentially from the bottom of a drawing. By adhering the respective films 111 to 113 to each other, one laminated film (optical film 11) is constituted.

Referring to FIG. 3 , another flat plate work 1 has a retardation film 115 as an optical film 11 . Moreover, the surface protection film 16 is laminated|stacked on the surface of the said optical film 11 (the surface of retardation film 115) via the adhesive layer 17. The surface protection film 16 may be peeled off from the surface of the optical film 11 (retardation film 115) along with the pressure-sensitive adhesive layer 17, for example. In addition, although it has the adhesive layer 12 and the separator film 13 on the back surface of the optical film 11 in FIG. 3, you may not have the said adhesive layer 12 and the separator film 13. In addition, the flat work 1 including the optical film 11 is not limited to the layer structure of FIGS. 2 and 3 and can be variously changed. For example, the flat work 1 may contain two or more layers of optical function films, or may be composed of only one layer of optical function films.

[Overview of System Including Plate Work Accumulator]

4 and 5 show a system incorporating the integrated device of the present invention. The system of this illustrated example can be implemented at least until the flat work obtained from the web is collected and collected and sent to the next process.

Referring to FIGS. 4 and 5 , the system comprises a work production zone Z1 for producing flat workpieces, and a work transfer zone for transporting flat workpieces 1 obtained in the work production zone Z1 to a work accumulation zone Z3. (Z2), a work accumulation zone Z3 in which flat workpieces 1 are accumulated and collected, and an accumulation in which the accumulated object 100 of flat workpieces 1 accumulated in the work accumulation zone Z3 is conveyed to the next step It has a water conveyance zone Z4 and a next process zone Z5 in which an arbitrary process is performed on the accumulated object 100 .

In the work production zone Z1, a work forming device D1 for forming a flat work 1 including a conveyor 26 conveying the flat work 1 downstream is installed. Hereinafter, this conveyor 26 is referred to as "upstream conveyor 26". The upstream conveyor 26 has, for example, an endless belt and is rotated by rollers. The upstream conveyor 26 transfers the formed flat plate work 1 to a conveyor described later. The work forming device D1 forms the flat work 1 from the web 180 . The work forming device D1 is, for example, a cutting device. The cutting device (work forming device D1) includes a cutting blade 21 for cutting the flat workpiece 1 from the web 180, and a cutting edge receiving sheet 22 for accommodating the tip of the cutting blade 21, It has a pedestal (23) arranged on the back side of the blade receiving sheet (22). The blade receiving sheet 22 is endless and is rotated by rollers. A plurality of flat plate works 1 can be continuously formed by cutting the web 180 by pressing the cutting blade 21 with the long strip-shaped web 180 conveyed from the upstream side. Also, usually, at least both sides of the web 180 in the width direction are recovered as the cut remainder 182 (so-called removed residue). The conveying direction of the web 180 and the recovery direction of the cut remainder 182 are indicated by arrows. As described above, the web 180 (and the flat work 1 to be formed) is a film including, for example, an optical film. In addition, in the illustrated example, a cutting pattern in which the remaining cut portion 182 occurs only on both sides is exemplified. In the case of this pattern, a plurality of flat works 1 in which the gaps between adjacent flat works 1 are substantially equal to the blade thickness of the cutting blade 21 are obtained. In addition, the web 180 may be cut in a cutting pattern in which the remainder of the cutting occurs between adjacent flat plate works 1 . In the case of this pattern, a plurality of flat workpieces 1 in which the gap between adjacent flat workpieces 1 is sufficiently larger than the blade thickness are obtained.

The conveyor 3 which conveys the flat workpiece|work 1 from the upstream side to the downstream side is installed in the work conveyance zone Z2. This conveyor 3 sequentially conveys the plurality of flat workpieces 1 from the upstream side to the downstream side.

Here, the transport direction is a direction orthogonal to the width direction in plan view. The downstream side is the side opposite to the upstream side. The downstream side refers to the side on which the flat plate work 1 is conveyed.

The flat plate work 1 is conveyed downstream by the conveyor 3 in a state in which a plurality of rows in the width direction and a plurality of rows in the conveyance direction are lined up. The number of rows of the flat plate work 1 is not particularly limited, and is two or more rows, preferably three or more rows. In FIG. 5, for convenience, the case where the flat work 1 is formed in 5 rows from the web 180, and the flat work 1 is lined up in 5 rows in the width direction and conveyed is illustrated. In addition, the number of rows refers to the number of flat workpieces 1 lined up in the width direction.

In addition, in FIG. 5, the case where the planar view substantially rectangular (substantially rectangular shape) flat plate workpiece 1 is formed by the workpiece|work forming apparatus D1 is illustrated. However, the flat plate work 1 formed is not limited to a substantially rectangular shape (substantially rectangular shape).

In addition, in FIG. 5, the case where the planar view substantially rectangular flat plate work 1 is conveyed in the state in which one side (for example, the side along the long axis) is substantially parallel to the conveyance direction is illustrated. However, it is not limited to this, and flat work 1 may be conveyed in a state in which one side (for example, the side along the long axis) is inclined with respect to the conveyance direction. An inclination with respect to the conveying direction means that it is approximately parallel and not approximately perpendicular. The approximate parallel is meant to include not only strict parallelism, but also an error range. For example, approximately parallel is within a range of ±5 degrees of strict parallelism, and preferably within a range of ±3 degrees of strict parallelism. The approximate right angle is meant to include an error range as well as a strict right angle. For example, the approximate right angle is within the range of exact right angle ±5 degrees, preferably within the range of exact right angle ±3 degrees.

The conveyor 3 has a conveying surface 3a on which the flat workpiece 1 is loaded and conveyed. The conveyor 3 has, for example, an endless belt and is rotated by rollers. The upper surface of the belt constitutes the conveyance surface 3a. In Fig. 5, a belt-shaped belt is used as the belt. Moreover, as a belt of the conveyor 3, as shown in FIG. 6, you may use the linear belt 32. A plurality of linear belts 32 are installed at predetermined intervals (an interval at which the flat workpiece 1 does not fall) in the conveying direction. In the case of using the linear belt 32, the conveying surface 3a of the conveyor 3 is composed of the upper surfaces of the plurality of linear belts 32 in succession.

The circumferential speed of the conveyor 3 is set equal to or faster than that of the upstream conveyor 26 . In the illustrated example, the circumferential speed of the conveyor 3 is higher than the circumferential speed of the upstream conveyor 26 . Accordingly, the flat workpiece 1 transferred to the conveyor 3 from the upstream conveyor 26 is rapidly conveyed downstream. For this reason, the space between the flat workpieces 1 during conveyance on the upstream conveyor 26 is dense, but the space between the flat workpieces 1 during conveyance on the conveyor 3 becomes relatively large. As the circumferential speed of the conveyor 3 increases, the space between the flat plates 1 conveyed on the conveyor 3 increases.

In the work accumulation zone Z3, the flat work 1 accumulation device D3 is installed. The accumulator D3 is arranged outside the downstream edge 3b of the conveyor 3 . The accumulation device D3 has a holding member 4 holding the accumulation 100 . The accumulation 100 is formed by overlapping a plurality of flat workpieces 1 in the thickness direction. Details of the integrated device D3 will be described later.

A conveyance device D4 for moving the holding member 4 of the accumulation device D3 is installed in the accumulation object conveyance zone Z4. The conveying device D4 connects at least the work accumulation zone Z3 and the next process zone Z5, and is endless (annular) in a planar view shown in FIG. 5, for example. The conveying device D4 includes a passage part 9 disposed annularly in plan view, including a work accumulation zone Z3 and a next process zone Z5, and a plurality of movable bodies movably installed in the passage part 9 (shown). omitted). The holding member 4 carrying the accumulated object 100 (plural flat workpieces 1) is moved to the next process zone Z5 via the conveying device D4, and the accumulated material 100 is moved to the next process zone Z5. ) is withdrawn. The empty holding member 4 is again moved to the work accumulation zone Z3 via the conveying device D4, and the flat workpiece 1 is accumulated on the holding member 4 again. By repeating this, a series of operations of integrating and collecting the flat work 1 continuously manufactured from the web 180 and conveying it to the next step are performed. The movement of the holding member 4 is indicated by arrows in FIGS. 5 and 6 . 5 and 6 show a state in which five holding members 4 as one set are arranged in a dispersed manner at three locations in the transport device D4, but the number of holding members 4 is not limited to this. no. In practice, a number of holding members 4 are attached to the conveying device D4.

In addition, it goes without saying that the operation of each device and members and parts constituting the device in the present invention is controlled by a control unit (not shown) including a computer.

The next process zone Z5 is a zone in which an arbitrary process is performed on the accumulated object 100 or each flat work 1 constituting the accumulated object 100 . As the next step, inspection of the flat workpiece 1, box packaging of the accumulated object 100, and the like are listed. Symbol D5 denotes a work table or the like of the next process.

[Platform Work Accumulator]

FIG. 7 is a plan view of the integrated device D3, FIG. 8 is a right side view seen from the direction of arrow VIII in FIG. 7, and FIG. 9 is a front view seen from the direction of arrow IX in FIG. In each figure, the upstream side of the conveyor 3 is abbreviate|omitted. In FIG. 7, the drive devices 72 and 82 of the stopper portion 7 and the false bottom portion 8 are not shown, and the conveyor 3 and the transport device D4 are not shown in FIG.

Referring to FIGS. 7 to 9 , a holding member 4 having a partition 5 is disposed outside the downstream edge 3b of the conveyor 3 . The holding member 4 has a partition part 5 and a receiving part 6 provided under the partition part 5. The receiving part 6 is a part for loading the accumulated object 100. The receiving part 6 extends to one side of the partition part 5 (one side in the width direction). The holding member 4 having the receiving portion 6 has a substantially L-shape in a front view.

The partition part 5 (holding member 4) is provided at least corresponding to each row of the flat workpiece|work 1 conveyed by the conveyor 3. Adjacent partitions 5 divide accommodating portions 42 for accumulating the flat workpieces 1, and preferably, adjacent partitions 5 and receiving portions 6 between the partitions 5 are The accommodating part 42 is partitioned off. The accommodating part 42 is a space accommodating the accumulated object 100 . The minimum number of partitions 5 (holding members 4) disposed outside the downstream edge 3b of the conveyor 3 is the number of rows of the flat workpiece 1. In order to reliably form the accommodating portion 42 for accumulating the flat work 1 with the adjacent partition 5, the outer side of the downstream edge 3b of the conveyor 3 has the hot water of the flat work 1 + It is preferable that the number of partitions 5 (holding members 4 having partitions 5) of 1 are disposed at intervals in the width direction. 7 to 9 exemplify a case in which four rows of flat workpieces 1 are conveyed by the conveyor 3, and therefore five partitions 5 (holding members) are placed on the downstream edge 3b of the conveyor 3. (4)) is arranged. However, as described above, the number of heats of the flat plate work 1 is not limited. The number of partitions 5 (holding members 4) disposed outside the downstream edge 3b of the conveyor 3 is appropriately set according to the number of rows of the flat workpiece 1.

A plurality of holding members 4 lined up in the width direction are each independently fixed to a movable body (not shown) of the transport device D4 via a connecting portion 91 . A moving body not shown is installed in the passage part 9 of the conveying device D4. The movable body can stop at an arbitrary position of the passage part 9 and can move along the passage part 9 at an arbitrary speed. Therefore, the plurality of holding members 4 are each independently attached to the passage portion 9 via a movable body in a movable state. In addition, the passage part 9 is fixed to its installation place (a frame of an apparatus, etc.). A plurality of holding members 4 having partitions 5 are each independently displaceable in the width direction in the movable body. The displacement means positioning and stopping at an arbitrary position, and arbitrarily changing the stopped position. That is, each of the partitions 5 (holding member 4) can independently stop at a predetermined position and move along the passage 9 at a predetermined speed. Therefore, it is possible to arbitrarily change the interval (interval in the width direction) of the neighboring partitions 5 (holding member 4), and the interval is determined at the time of accumulation of the flat work 1 or of the accumulation of the accumulation 100. It is appropriately set at the time of conveyance or the like.

In addition, the number of partitions 5 (holding member 4) attached to the conveying device D4 is not limited to the number of rows of the flat work 1 + 1, and in practice, the number of partitions ( 5) (Holding member 4) is each independently attached to conveying device D4.

Each of the partitions 5 has an upper surface 5a temporarily supporting the flat plate work 1 going out of the downstream edge 3b by conveyance of the conveyor 3. The upper surface 5a of the partition part 5 is flat. Although the upper surface 5a of the partition part 5 may be inclined with respect to the horizontal, it is preferably horizontal. In addition, each partitioning part 5 is arranged so that the upper surface 5a of each partitioning part 5 is in the same plane as the conveying surface 3a of the conveyor 3, or located slightly below the conveying surface 3a. . In the example of illustration, the upper surface 5a of each partition part 5 is located slightly below the conveying surface 3a of the conveyor 3 (refer FIG. 8). Since the upper surface 5a is located below, the flat workpiece 1 is smoothly carried and transferred from the conveyor 3 to the upper surface 5a of the partition part 5, and falls into the receiving part 42 by gravity. it becomes easier to do

Specifically, in the side view shown in FIG. 8 , the partition portion 5 has an upper portion 51 having an upper surface 5a extending in the transport direction and a side wall portion extending in the vertical direction. A sliding treatment may be applied to the upper surface 5a of the partition 5 as needed. As the sliding treatment, methods such as applying a sliding agent such as silicone to the upper surface 5a of the partition portion 5 or attaching a slipping tape (a tape having a surface) to the partition portion 5 are listed. In the illustrated example, a slip tape 56 is attached to the partition portion 5, and in this case, the upper surface of the tape 56 constitutes the upper surface 5a of the partition portion 5. By applying the sliding treatment to the upper surface 5a of the partition 5, the flat workpiece 1 moves while sliding smoothly on the upper surface 5a. Preferably, a slip tape 56 having conductivity is used. By using the slip tape 56 having conductivity, generation of static electricity can be prevented. The side wall portion may have a plate shape. Since the bottom part 8 described later protrudes upward from the receiving part 6, in the illustrated example, the side wall part is composed of a plurality of rod-shaped parts 52. Upper portions of the plurality of rod-shaped portions 52 are connected to upper portions 51, respectively, and receiving portions 6 are connected to lower portions of the plurality of rod-shaped portions 52, respectively. The plurality of rod-shaped portions 52 are connected to the upper portion 51 with gaps 52c therebetween. When the plurality of rod-shaped portions 52 are continuous while having the gap 52c, the plurality of rod-shaped portions 52 form a wall.

The plurality of holding members 4 may be the same or different. In the illustrated example, two types of holding members 4 having different receiving portions 6 are alternately arranged in the width direction. In the following description, when it is necessary to distinguish between two types of holding members, one is referred to as "first holding member 4-1" and the other is referred to as "second holding member 4-2", Both are collectively referred to as "holding member 4".

10 and 11 show the first holding member 4-1.

The 1st holding member 4-1 has the partition part 5 and the receiving part 6 provided under the partition part 5. The receiving part 6 of the 1st holding member 4-1 is called "1st receiving part 6-1". As described above, the partition portion 5 has an upper portion 51 having a sliding upper surface 5a and a side wall portion composed of a plurality of rod-shaped portions 52 (a plurality of rod-shaped portions 52). The 1st receiving part 6-1 is provided in multiple numbers, and each consists of a rod-shaped member. Since the plurality of first receiving parts 6-1 are continuously arranged with a gap therebetween, the plurality of first receiving parts 6-1 form an accommodation bag. The some 1st receiving part 6-1 is arrange|positioned at mutually same height position (horizontal), as shown in FIG.10(b). In addition, regarding the height position of the some 1st receiving part 6-1, it is not limited to mutually same height, The 1st receiving part 6-1 on the left side of the paper shown in FIG. 10(b) is on the right side of the paper It may be lower than the 1st receiving part 6-1.

Each of the plurality of first receiving portions 6-1 is provided extending from below the plurality of rod-shaped portions 52 to one side in the width direction. The base of the first receiving portion 6-1 is connected downward to the rod-shaped portion 52, and the distal end of the first receiving portion 6-1 (the end on the opposite side to the base portion) is free. The outer diameter of the 1st receiving part 6-1 becomes small toward the tip part in order to be able to reliably insert into the insertion hole 66 of the 2nd receiving part 6-2 mentioned later. The length (length in the extending direction) of the first receiving portion 6-1 is not particularly limited, as long as it is greater than or equal to the extent that the accumulated object 100 is loaded and does not fall naturally.

The 1st receiving part 6-1 may be connected so that it may extend at right angles with respect to the partition part 5 (the side wall part which consists of rod-shaped part 52). Alternatively, when conveying the accumulated object 100 to the next process zone Z5, in order to prevent the accumulated object 100 from falling inadvertently, the upper surface of the first receiving portion 6-1 is provided with the partition portion 5 ( It may make an acute angle with respect to the rod-shaped part 52, and may extend. That is, the first receiving portion 6-1 so that the angle α formed by the upper surface of the first receiving portion 6-1 and the side surface of the partition portion 5 (the side wall portion composed of the rod-shaped portion 52) becomes an acute angle. may be inclined with respect to the partition part 5. In this case, the front end of the 1st receiving part 6-1 is located above the base part of the 1st receiving part 6-1. The angle α is not particularly limited, but when it is too close to 90 degrees, it does not substantially change to a right angle. From this point of view, the angle α is greater than 0 degree and less than or equal to 20 degrees, and more than 0 degree and less than or equal to 5 degrees, for example.

12 and 13 show the second holding member 4-2.

Like the first holding member 4-1, the second holding member 4-2 has a partition 5 and a receiving part 6 provided below the partition 5. The receiving part 6 of the 2nd holding member 4-2 is called "the 2nd receiving part 6-2". The partition portion 5 has an upper portion 51 and a side wall portion (a plurality of rod-shaped portions 52). Preferably, the partition part 5 of the 2nd holding member 4-2 is the same structure as the partition part 5 of the 1st holding member 4-1.

The 2nd receiving part 6-2 is provided in multiple numbers, and each consists of a rod-shaped member. Since the plurality of second receiving portions 6-2 are continuously arranged with a gap therebetween, the plurality of second receiving portions 6-2 form a receiving base. As shown in Fig. 12(b), the plurality of 2nd receiving parts 6-2 are arrange|positioned at mutually same height positions (horizontal). In addition, regarding the height position of the some 2nd receiving part 6-2, it is not limited to the mutually same height, The 2nd receiving part 6-2 of the left side of the paper sheet shown in FIG. 12(b) is on the right side of the paper sheet It may be lower than the 2nd receiving part 6-2. The plurality of second receiving portions 6-2 are provided extending from below the plurality of rod-shaped portions 52 to one side in the width direction, respectively.

The second receiving portion 6-2 has an insertion space 64 into which the first receiving portion 6-1 is inserted in the extending direction. For example, the second receiving portion 6-2 is made of a long and thin rod having a continuous U-shape in the direction in which it extends (the second receiving portion 6-2 is shaped like a pipe with the upper surface removed done). The base of the second receiving portion 6-2 is connected downward to the rod-shaped portion 52, and the distal end of the second receiving portion 6-2 (the end on the opposite side to the base portion) is free. In addition, an insertion hole 66 is opened below the rod-shaped portion 52 so that the first receiving portion 6-1 can be inserted therein. The length (length in the direction of extension) of the second receiving portion 6-2 is not particularly limited, as long as it is greater than or equal to the extent that the accumulated object 100 is loaded and does not fall naturally.

The 2nd receiving part 6-2 may be connected so that it may extend at right angles with respect to the partition part 5 (rod-shaped part 52). Alternatively, when conveying the accumulated object 100 to the next process zone Z5, in order to prevent the accumulated object 100 from falling carelessly, the upper surface of the second receiving portion 6-2 is the first receiving portion 6 -1), it may make an acute angle with respect to the partition part 5 (rod-shaped part 52), and may extend. Also about the angle α of the second receiving portion 6-2, similarly to the first receiving portion 6-1, for example, it exceeds 0 degrees and is 20 degrees or less, and also exceeds 0 degrees and is 5 degrees or less. am.

The 1st holding member 4-1 and the 2nd holding member 4-2 are arrange|positioned alternately in the width direction. The adjacent 1st holding member 4-1 and the 2nd holding member 4-2 may overlap the 1st receiving part 6-1 and the 2nd receiving part 6-2.

Specifically, as shown in FIG. 14 and FIG. 15, each holding member 4 is moved so that the space|interval of the adjacent holding member 4 may become small. At this time, the 1st receiving part 6-1 passes through the insertion hole 66 of the 2nd holding member 4-2, and enters the insertion space 64 of the 2nd receiving part 6-2.

In this invention, the receiving part 6 of the adjacent holding member 4 may have the same structure. However, when the receiving part 6 has the same structure, if adjacent holding members 4 are brought close to each other, the front end of the receiving part 6 of one holding member 4 is the receiving part of the other partition part 5. (6) interfere with the donation. Therefore, when the receiving part 6 has the same structure, the minimum value of the space|interval of the holding member 4 (partition part 5) becomes the length of the receiving part 6. When this point and the 1st holding member 4-1 and the 2nd holding member 4-2 are arrange|positioned alternately in the width direction, as mentioned above, the 1st receiving part 6-1 is the 2nd receiving member It enters the insertion space 64 of the part 6-2, and the 1st receiving part 6-1 and the 2nd receiving part 6-2 overlap without interference. For this reason, it is also possible to bring adjacent holding members 4 close, and to make the space|interval of those holding members 4 (partition part 5) smaller than the length of the receiving part 6. Thus, by alternately arranging the 1st holding member 4-1 and the 2nd holding member 4-2 which mutual receiving part 6 does not interfere, as shown in FIG. 1 and FIG. 15, several It is also possible to make the holding member 4 all at once.

The forming material of the holding member 4 (the 1st and 2nd holding member 4-1, 4-2) is not specifically limited. The holding member 4 is made of a material with excellent strength, such as metal or hard resin.

7 to 9, the integrated device D3 has a stopper portion 7. The stopper portion 7 is disposed on the downstream side of the partition portion 5 . The stopper portion 7 is provided to prevent the flat plate workpiece 1 from advancing while sliding on the upper surface 5a of the partition portion 5. The stopper portions 7 are respectively provided between the partition portions 5 adjacent to each other at least. In the illustrated example, the same number of stopper portions 7 as the number of holding members 4 arranged outside the downstream edge 3b of the conveyor 3 is provided. The stopper portion 7 is arranged so as not to come into contact with the partition portion 5 . For example, the stopper parts 7 are respectively arranged in the middle of the adjacent partition part.

As shown in FIG. 8, the stopper part 7 should just be provided so that it may intersect at least the upper surface 5a of the partition part 5 with respect to the same plane. For example, the stopper portion 7 is constituted by a plate-like body. The stopper portion 7 made of a plate-shaped body includes a portion intersecting the upper surface 5a of the partition portion 5 with respect to the same plane, and extends vertically from the portion.

It is preferable that the stopper part 7 extends to the vicinity of the receiving part 6, as shown in FIG. In the illustrated example, the stopper portion 7 is extended to such an extent that the lower end portion 7d of the stopper portion 7 is located slightly above the receiving portion 6 . The length of the stopper portion 7 in the width direction is not particularly limited, and it is preferable that it does not come into contact with the partition portion 5.

The material for forming the stopper portion 7 is not particularly limited. The stopper portion 7 is made of a material having excellent strength, such as metal or hard resin.

Each stopper part 7 can be moved in the vertical direction. For example, each stopper part 7 is attached to the driving device 72 via a coupling part 71 . The drive device 72 is fixed to its installation site (a frame of the device, etc.). When the plate work 1 is stacked, each stopper portion 7 is arranged so as to intersect the upper surface 5a of the partition portion 5 on the same plane. When the holding member 4 is moved, each stopper portion 7 is moved upward by a driving device 72 so that the holding member 4 does not interfere with the stopper portion 7 . For example, each stopper part 7 is evacuated upward from the upper surface 5a of the partition part 5 so that it may not intersect with the upper surface 5a of the partition part 5.

If necessary, you may set a driving device so that each stopper part 7 can be moved in the conveyance direction. The moving direction of the stopper part 7 is indicated by a thick arrow in FIG. 8 . Depending on the plan view shape and size of the flat workpiece 1, there is a possibility that the stopper portion 7 may not touch the flat workpiece 1 advancing over the upper surface 5a of the partition portion 5. If the stopper part 7 is movable on the downstream and upstream sides in the conveying direction, the position of the stopper part 7 is closer to the downstream edge 3b of the conveyor 3 or away from the downstream edge 3b can do. By appropriately adjusting the position of the stopper portion 7 according to the plan view shape and size of the flat workpiece 1, the advancing flat workpiece 1 can be brought into contact with the stopper portion 7 reliably.

If necessary, you may set a driving device so that each stopper part 7 can be moved in the width direction. Since the stopper portion 7 can be displaced in the width direction, the position of each stopper portion 7 in the width direction can be appropriately adjusted according to the spacing between the partition portions 5 adjacent to each other.

In addition, the integrated device D3 has a flexible bottom 8 capable of moving up and down. The false bottom part 8 functions as a support for temporarily supporting the flat plate work 1 falling into the receiving part 42.

The false bottom 8 is provided so as to be able to enter and exit the receptacle 42 . For example, the tentative bottom 8 is made of a plate-like body (or may be a rod-like body) through which the gap 52c of the rod-shaped portion 52 of the holding member 4 can enter. In the illustrated example, the tentative bottom portion 8 is composed of a plurality of plate-like bodies entering the gaps 52c of all the rod-like portions 52. The material for forming the false bottom 8 is not particularly limited. The false bottom 8 is made of a material having excellent strength, such as metal or hard resin. The upper end 8a of the false bottom 8 may have a flat shape, but is preferably an arc shape as shown in FIG. 8 from the viewpoint of preventing scratches on the falling flat workpiece 1. Further, the upper end 8a of the false bottom 8 may be formed of a cushioning material such as rubber, or a cushioning material such as rubber may be provided on the upper end 8a of the false bottom 8 (not shown).

The plurality of tentative bottoms 8 may be positioned at the same height. That is, when viewed from the side, a plurality of false bottoms 8 may be provided so that a virtual line connecting the upper ends 8a of each false bottom 8 is horizontal. Alternatively, as shown in FIG. 8, it is preferable that the plurality of tentative bottoms 8 gradually lower toward the stopper portion 7 side (downstream side). That is, it is preferable that a plurality of false bottoms 8 are provided so that an imaginary line connecting the upper end 8a of each false bottom 8 is inclined in the side view. Since the upper end 8a of each tentative bottom part is inclined so as to be lowered toward the stopper part 7 side, the flat plate work 1 falling into the housing part 42 and loaded on the upper end part 8a of the tentative bottom part 8 is It moves to the stopper part 7 along the . Since the moved flat workpiece 1 comes into contact with the stopper portion 7 and stops, the flat workpiece 1 is stacked in a state in which the flat workpieces 1 are aligned up and down. The degree of the inclination is not particularly limited, but if it is too small, it becomes difficult for the flat workpiece 1 to move toward the stopper portion 7 side. The inclination angle β of the upper end 8a of the false bottom 8 is, for example, 5 degrees or more and 20 degrees or less, and preferably 7 degrees or more and 15 degrees or less. As shown in FIG. 8, the inclination angle β refers to an angle forming an imaginary line connecting the upper end 8a of each lower part 8 and the horizontal plane.

A false bottom 8 may be provided for each holding member 4 so that each holding member 4 can independently enter and exit the accommodating portion 42 of the plurality of holding members 4 . Further, a false bottom 8 may be provided so as to be able to simultaneously enter and exit the accommodating portion 42 of the plurality of holding members 4 . In the illustrated example, the tentative bottom portion 8 can simultaneously enter and exit the accommodating portions 42 of the plurality of holding members 4 disposed outside the downstream edge 3b of the conveyor 3. In this case, the plate-like body constituting the tentative bottom portion 8 has an elongated shape that crosses each holding member 4 and extends in the width direction (see Fig. 9).

The false bottom 8 is attached to the drive device 82 via a connecting portion 81 so as to be able to move in the vertical direction. The drive device 82 is fixed to its installation site (a frame of the device, etc.). When stacking the flat work pieces 1, the tentative bottom portion 8 enters the gap 52c between the adjacent bar-shaped portions 52 and protrudes upward from the receiving portion 6 of the holding member 4 (Fig. 8 and 9).

[Accumulation method of flat work]

Next, the procedure of integrating and collecting the plate work 1 will be described.

The method of integrating flat workpieces 1 of the present invention includes a conveyor 3 for conveying a plurality of flat workpieces 1 from an upstream side to a downstream side, and a conveyor 3 disposed outside the downstream edge 3b of the conveyor 3. This is implemented using an integrating device D3 having a plurality of partitions 5 and a stopper 7 disposed on the downstream side of the partitions 5 .

The method is a state in which a plurality of flat workpieces 1 are lined up in a plurality of rows in the width direction and a plurality of rows in the conveying direction, which is a direction perpendicular to the width direction, on the conveying surface 3a of the conveyor 3, each of the flat workpieces 1 In the process of sequentially conveying, each flat workpiece 1 coming out of the downstream edge 3b by the conveying of the conveyor 3 is advanced while sliding over the upper surface 5a of the partition part 5. The step of making the flat plate work 1 fall from the upper surface 5a of the partition part 5 while bringing the flat plate work 1 into contact with the stopper part 7, and between the neighboring partition parts 5 It has a process of sequentially integrating into the accommodating part 42.

Here, the case where the flat workpiece 1 is formed in a state in which one side (for example, the side along the long axis) is inclined with respect to the conveying direction by the work forming device D1, and conveyed in the inclined state Explain.

16 is a plan view showing a state in which the flat workpiece 1 is conveyed by the upstream conveyor 26 and a state conveyed by the conveyor 3.

Referring to Fig. 16, a plurality of flat workpieces 1 formed by the work forming apparatus D1 are lined up in a dense state between rows and rows, and conveyed downstream on an upstream conveyor 26. For example, the conveyor 3 has a higher circumferential speed than the upstream conveyor 26 . Each flat workpiece 1 moved from the upstream conveyor 26 to the conveyor 3 is conveyed with the inter-row and inter-column widths widened while maintaining an inclined state with respect to the conveying direction.

On the other hand, outside the downstream edge 3b of the conveyor 3, a plurality of holding members 4 including partitions 5 are set at predetermined positions. As shown in FIG. 17, the distance W5 between the cores Y and Y of the neighboring partitions 5 is the distance W1 between the centers X and X of the flat workpieces 1 adjacent to each other in rows. As such, the holding member 4 including the partition portion 5 is positioned and set. In addition, the holding member 4 including the partition part 5 is shifted in one direction in the width direction from the center X of the plate work 1 of each row in which the core Y of each partition part 5 is conveyed. It is positioned and set. Preferably, the holding member 4 including the partition part 5 is positioned so that the center X of the flat workpiece 1 of each row being conveyed does not overlap with the upper surface 5a of each partition part 5. It is determined and set.

Further, as shown in Fig. 14, the plurality of holding members 4 before being disposed outside the downstream edge 3b are compactly arranged and moved by the conveying device D4. Then, on the outer side of the downstream edge 3b of the conveyor 3, the arranged plurality of holding members 4 are each spread out and positioned, and are arranged at the above-mentioned intervals.

The flat workpiece 1 conveyed by the conveyor 3 goes out of the downstream edge 3b and is carried on the upper surface 5a of the partition 5. By the extrusion of the conveyor 3, as shown in Figs. 18(a) and (b), the flat plate work 1 advances while sliding on the upper surface 5a of the partition part 5. In other words, the conveyor 3 advances the flat workpiece 1 while sliding over the upper surface 5a of the partition 5. As shown in FIG. 19 , the front end corner portion 1d of the flat plate work 1 is further extruded while touching the stopper portion 7, and the flat work 1 rotates. In the figure, a flat plate work in the middle of rotation is indicated by a two-dot dashed line and is indicated by the reference numeral 1'. Since the center (X) of the plate work 1 is out of the core (Y) of the partition part 5 to one side in the width direction, the flat plate work 1 rotates between adjacent partition parts 5 (center (X) Gravity falls to the receiving portion 42 on the shifted side (see Fig. 20). In addition, in FIG. 20, the stopper part 7 is shown by the dashed-dotted line, and the drive device and conveyance device D4 are not shown (same as FIG. 25).

The flat workpieces 1 that have fallen into the accommodating portion 42 are sequentially accumulated in a state of inclination with respect to the horizontal. By rotating in detail, the flat workpiece|work 1 falls into the accommodating part 42 with the short side (side along the long axis) of one side along the width direction facing down. That is, by rotating itself, the flat plate workpiece 1 falls into the housing part 42 while the long axis becomes a state substantially parallel to the width direction in a planar view. The flat plate work 1 that has fallen is in contact with a corner partitioned by the bottom part 8 and the partition part 5 on one side of the short side, and the short side on the opposite side of the flat plate work 1 is in contact with the partition part 5 next to it. to contact Accordingly, the flat plate work 1 is inclined and accommodated in the accommodating portion 42 . When the inclined shape is made in this way, the edges (short side on one side and short side on the opposite side) on both sides of the flat work 1 only come into contact with the partition portion 5, so that the back surface of the flat work 1 is not scratched. It can be prevented.

In addition, since the tentative bottom 8 is provided, the drop distance of the flat workpiece 1 can be made as small as possible, and the drop impact on the flat workpiece 1 can be reduced. That is, in the present invention, the false bottom part 8 does not have to be provided, but in the absence of this, the flat workpiece 1 falls from the upper surface 5a of the partition part 5 to the receiving part 6 at once. In this respect, by locating the false bottom 8 above the receiving portion 6, the distance at which the flat workpiece 1 falls at one time can be reduced.

Further, since the upper ends 8a of the plurality of false bottoms 8 are inclined, the flat plate work 1 in contact with the upper ends 8a of the false bottoms 8 moves to the stopper portion 7 according to the inclination. For this reason, in the accommodating part 42, the flat workpieces 1 are accumulated in a state in which they are in contact with the stopper part 7, and an accumulation in which the upper and lower flat workpieces 1 are neatly arranged is obtained.

In this way, each flat workpiece 1 conveyed sequentially by the conveyor 3 rotates on the upper surface 5a of the partition portion 5 corresponding to each row, and is accommodated in the accommodating portion 42, respectively. It is necessary to prevent the plate work 1 accommodated in each accommodating part 42 from protruding upward from the upper surface 5a of the partition part 5. Because of this, when the number of accumulated flat works 1 is increased, the false bottom 8 is lowered accordingly. When a planned number of flat workpieces 1 are accumulated in the accommodating portion 42, as shown in FIG. is raised to evacuate to the upper surface (5a) of the partition part (5). When the bottom part 8 is lowered, the inclined accumulation 100 is carried on the receiving part 6 and moved. By retracting the false bottom portion 8 and the stopper portion 7, the holding member 4 can be moved. Although the holding member 4 may be conveyed to the next step while the stacked object 100 is inclined, it is unstable as long as it remains inclined. For this reason, from the state shown in FIG. 21, each holding member 4 is moved in the width direction, and the space|interval of the adjacent holding member 4 is expanded, respectively. In this way, as shown in FIGS. 22(a) and (b), the back surface of the accumulated object 100 is placed along the receiving portion 6 top. When the holding member 4 is moved in a state where the back surface of the accumulated object 100 is in contact with the receiving portion 6, the accumulated object 100 can be stably conveyed to the next step. In particular, since the receiving portion 6 extends at an acute angle with respect to the partition portion 5, as shown in the figure, the accumulation 100 in contact with the receiving portion 6 faces the front end of the receiving portion 6. It slopes upward as a whole. For this reason, when conveying the accumulated object 100 held by the holding member 4, it can prevent that the flat workpiece|work 1 falls off from the front end side (free end side) of the receiving part 6.

When the holding member 4 accommodating the accumulated objects 100 is moved, the waiting empty holding member 4 is immediately disposed outside the downstream edge 3b of the conveyor 3 . After disposing the empty holding member 4, the stopper portion 7 is lowered and the tentative bottom portion 8 is raised, thereby setting the state shown in FIGS. 7 to 9. And similarly, flat work 1 is accumulated in accommodating part 42 . After that, this is repeated, the plate work 1 can be continuously accumulated and collected, and conveyed sequentially to the next step.

<Second Embodiment>

In the column of the above <First Embodiment>, the case where the flat work 1 is lined up on the conveying surface 3a and conveyed in a state where one side of the flat work 1 is inclined with respect to the conveying direction has been described, but here 1 A case where the flat workpiece 1 is conveyed in a state in which the sides are substantially parallel to the conveying direction will be described.

A plurality of flat workpieces 1 formed by the work forming apparatus D1 are conveyed downstream in a state in which one side is substantially parallel to the conveyance direction (see Fig. 5). For example, the flat workpiece 1 is conveyed in a state in which the major axis is substantially parallel to the conveyance direction.

Fig. 23 is a plan view of an integration device D3 implementing the integration method of the second embodiment.

Referring to Fig. 23, outside the downstream edge 3b of the conveyor 3, a plurality of holding members 4 including partitions 5 are set at predetermined positions. As described in the first embodiment, in each holding member 4, the distance W5 between the cores Y of the neighboring partitions 5 is the center (X) of the flat workpieces 1 adjacent to each other in rows. , X), and the holding member including the partition part 5 so that the core Y of each partition part 5 is shifted from the center X of the corresponding flat plate work 1. (4) is positioned and set.

The flat workpiece 1 conveyed by the conveyor 3 goes out of the downstream edge 3b and is carried on the upper surface 5a of the partition 5. By the extrusion of the conveyor 3, the flat plate work 1 advances while sliding along the upper surface 5a of the partition 5 along the extension direction of the upper surface 5a of the partition 5.

As shown in FIGS. 24 and 25, when the leading edge of the flat work 1 in the traveling direction touches the stopper portion 7, the impact causes the flat work 1 to lose balance, and the flat work 1 Gravity falls to the accommodating part 42 on the side where the center X is shifted. In detail, the flat plate work 1 advancing the upper surface 5a of the partition part 5 is one in which the center X of the flat plate work 1 does not overlap with the upper surface 5a of the partition part 5 and a flat plate When the workpiece 1 touches the stopper portion 7, it falls so as to collapse sideways. In the case of this embodiment, the plate work 1 does not rotate, and the plate work 1 on the upper surface 5a of the partition part 5 is off center with respect to the upper surface 5a of the partition part 5. It collapses on its side and falls into the receiving part 42 on that side. Therefore, the flat workpiece 1 is accommodated in the accommodating portion 42 in the same direction as during conveyance (that is, the flat workpiece 1 is accommodated in the accommodating portion 42 in a state in which the long axis is substantially parallel to the conveyance direction). ).

Since the distance between the adjacent partitions 5 is smaller than the minor axis length of the flat work 1, the flat work 1 that has fallen into the housing part 42 is tilted with respect to the horizontal, as in the first embodiment. are sequentially accumulated. In this way, the flat plate workpieces 1 of each row are dropped from the upper surface 5a of the partition section 5 corresponding to each row to the accommodating section 42 and accumulated one by one.

After that, as in the first embodiment, when a predetermined number of flat workpieces 1 are accumulated in the accommodating portion 42, the stopper portion 7 and the false bottom portion 8 are evacuated, and the accumulated objects 100 are placed in the receiving portion. (6) The holding member 4 is transported to the next step in a state of being in contact with the top.

Further, in this embodiment, the case where the flat workpiece 1 is conveyed in a state in which the major axis is substantially parallel to the conveying direction has been described with illustration, but the flat work 1 is conveyed in a state in which the minor axis is substantially parallel to the conveying direction. In the case of conveyance, it can be carried out in the same way.

<Third Embodiment>

In the holding member 4 of each of the above embodiments, the receiving portion 6 extends to one side of the partition portion 5 and is provided, but the receiving portion 6 extends to one side of the partition portion 5 and the opposite side thereof. You may use the holding member 4 which becomes.

26 shows the holding member 4 of the third embodiment.

This holding member 4 has the partition part 5, the right receiving part 6R, and the left receiving part 6L provided below the partition part 5. The right receiving part 6R extends to one side of the said partition part 5 in the width direction, and the left receiving part 6L extends to the opposite side. The right receiving portion 6R and the left receiving portion 6L are portions for loading the accumulated object 100. The holding member 4 which has these two receiving parts 6 has comprised the inverted T-shape in front view.

The right receiving part 6R and the left receiving part 6L are a shape extended long, and both receiving parts 6R and 6L may have the same shape. In order to prevent interference between the right receiving portion 6R of one holding member 4 and the left receiving portion 6L of the neighboring holding member 4 when the interval between the adjacent partitions 5 is reduced. , it is preferable to employ the same configuration as the first embodiment.

For example, the right receiving part 6R consists of a rod-shaped member similarly to the 1st receiving part 6-1 of the said 1st Embodiment. The left receiving part 6L has the insertion space 64 similarly to the 2nd receiving part 6-2 of the said 1st Embodiment. In addition, the upper surfaces of the right receiving part 6R and the left receiving part 6L make an acute angle with respect to the partition part 5, and may extend, or may extend at right angles (horizontal) with respect to the partition part 5.

Fig. 27 shows a state when the holding member 4 of the third embodiment is disposed outside the downstream edge 3b of the conveyor 3 at intervals. However, the conveyor 3 and the like are omitted and only the holding member 4 is meant.

In the case of using the holding member 4 of the third embodiment, the accommodating portion 42 is divided by the partitioning portion 5, the right receiving portion 6R, and the left receiving portion 6L adjacent to each other. During use, the flat workpiece 1 is accumulated in the accommodating portion 42 .

<Fourth Embodiment>

Although the receiving part 6 (the 1st receiving part 6-1 and the 2nd receiving part 6-2) of the holding member 4 of each said embodiment is mutually arrange|positioned at the same height position (horizontal), You may arrange|position in an inclined shape.

For example, as shown in FIG. 28, the plurality of receiving parts 6 may be gradually lowered toward the stopper part 7 side (downstream side) in the side view. That is, the some receiving part 6 may be provided so that the virtual line which connected the lower end part 6d of the some receiving part 6 in side view may incline. Since the plurality of receiving portions 6 are inclined toward the stopper portion 7 side, the plate work 1 falling to the receiving portion 42 and loaded on the upper end portion 8a of the tentative bottom portion 8 moves along the inclination to the stopper portion. It becomes easy to move to (7). The inclination angle γ of the plurality of receiving portions 6 exceeds 0 degree and is 5 degrees or less, for example, Preferably it exceeds 0 degree and is 3 degrees or less. As shown in FIG. 28, said inclination-angle (gamma) says the angle used as the virtual line which connected the lower end part 6d of the receiving part 6, and a horizontal plane.

<Fifth Embodiment>

Although the plurality of false bottoms 8 in each of the above embodiments are inclined, for example, as shown in FIG. 29, the upper ends 8a of the respective false bottoms 8 may be positioned at the same height. In this case, in the side view, the imaginary line connecting the upper end 8a of each false bottom 8 becomes horizontal.

<Sixth Embodiment>

In the present invention, in addition to the flat plate work 1 shown in the description of each of the above embodiments, flat plate works 1 of various planar view shapes can be integrated.
