Description

  The present invention relates to an improvement of a plate-like body conveyance device.

  Conventionally, as a conveying apparatus that sucks and conveys a plate-like body such as a veneer single plate or a thin metal plate from the upper surface side, for example, as disclosed in Patent Document 1, an appropriate number of elements constituting a belt conveyor-like conveyance mechanism is provided. Intake air having an intake member having an appropriate number of intake ports connected to an intake port of an appropriate number of intake devices via an open / close member such as an open / close valve that can be opened and closed in a timely manner on the inner peripheral side of the perforated belt The mechanism is arranged so that the intake port of the intake member faces an appropriate number of rows with respect to the row of holes of the perforated belt, and sucks the plate-like body indirectly through the perforated belt. As disclosed in Patent Document 2, Patent Document 3, and the like, an appropriate number of intake air and an appropriate number of intake air connected to the intake port of the intake air through an opening / closing member that can be opened and closed in a timely manner. An intake mechanism including an appropriate number of intake members having openings, and the intake port of the intake member is configured to carry a plate-like body. In addition to being arranged so as to be arranged in a double row following the direction, a suitable number of conveying belts and a regulating member that regulates the running position of each conveying belt on the inner peripheral side of each conveying belt (the regulating member is A conveyance mechanism having another function), and the conveyance belt is arranged so that each conveyance belt protrudes downward in the vicinity of each row of the intake ports. However, each type has the disadvantages and weak points described later.

  That is, in any of the above types, the suction force is generated by lowering the air density on the upper surface side of the plate-like body by sucking air through the suction mechanism. Since the suction force is restricted regardless of the number and size of the holes in the belt, in order to obtain a suction force sufficient for sucking and transporting the plate-like body, the capacity of the intake device is considerably large. As a result, there is a drawback that the cost of installing the intake mechanism and the cost of power consumption are increased, and the perforated belt is easily damaged from the hole portion. There is also a weak point that the cost increases. On the other hand, the latter type has the advantage that the transport belt is less likely to be damaged than the perforated belt, so that the maintenance cost of the transport belt can be relatively low. In addition, since the suction force is limited, it is necessary to considerably increase the capacity of the intake device, and there is still a problem that the cost of disposing the intake mechanism and the power consumption cost are increased.

  More specifically, as is apparent from the drawings of Patent Documents 2 and 3, the known type of this type is the intake member of the intake mechanism over substantially the entire surface facing the upper surface of the plate-like body. A portion facing the upper surface of the plate-like body by arranging a member such as a shielding plate that also serves as a regulating member that regulates the traveling position of the conveying belt on the inner circumferential side of the conveying belt of the conveying mechanism The substantially entire surface is substantially non-open to the atmosphere.

  Thus, when the configuration as described above is adopted, for example, when the plate-like body carried in via the carry-in conveyor positioned at the front of the carrying device is sucked and adsorbed to the carrying belt, the intake air of the intake member is drawn. The inflow of intake air to the mouth is mainly performed from the lower side or the obliquely lower side of the intake member in the vicinity of the intake port on the front end side of the plate-like body. And the rear side in the vicinity of the intake port of the intake member at the position facing the plate-like body immediately before the suction, but between the intake ports adjacent to each other in the direction orthogonal to the conveyance direction of the plate-like body In order to obtain a suction force necessary for stably adsorbing the plate-like body to the conveyor belt, the intake air is made narrow so that the interval between the rows of intake ports is narrow. The number of rows of mouths is considerably increased, and there is an intake device with a capacity adapted to the total area of the intake ports, or the intake air If the spacing of columns is wide of the need to Chodai the capacity of the intake device provided for each column of each intake port, consequently, the difficulty is real.

  Furthermore, the problem of insufficient suction force as described above is caused not only when the plate-like body is sucked from the carry-in conveyor, but also when the plate-like body adsorbed on the conveyor belt is transported. Naturally, for example, a veneer veneer having general-purpose dimensions (width in the fiber direction = about 2 m to 2.5 m, length in the direction perpendicular to the fiber direction = about 1 m to 1.3 m) (hereinafter simply referred to as a veneer) Thus, when sucking and transporting a plate-like body having a relatively large plate surface, the suction force acting on the central portion of the plate-like body is compared with the suction force acting on the four peripheral end portions of the plate-like body. As a result, the suction force tends to be insufficient as a whole. It needs to be large.

Incidentally, as described above, when a plate-like body having a relatively large plate surface is sucked, the suction force acting on the central portion of the plate-like body is changed to the suction force acting on the four peripheral end portions of the plate-like body. The reason for the significant decrease is considered to be that there is a difference between the density of air flowing around the four-circumferential edge of the plate-like body and the density of air that tends to stay near the central part. Was attached to the suction port of the vacuum cleaner, and an experiment was conducted to suck the flour spread on the floor from above through the suction tool. As expected, there was enough flour near the center of the suction tool. The phenomenon that could not be completely sucked was confirmed. Furthermore, to add another problem, intake / exhaust by a large-capacity intake machine causes a loud noise, and there is a disadvantage that the working environment is deteriorated.

  The present invention was developed to solve the problems and problems of the known conveying device. In a conveying device of the type that directly sucks a plate-like body in the vicinity of the conveying belt, Even if the interval between the intake ports adjacent to each other in the direction orthogonal to the transport direction is relatively wide, the board is configured so that effective intake is performed at the intermediate portion between the adjacent intake ports. The suction force and the power consumption of the intake mechanism are reduced so that the suction force acting on the four peripheral edges of the plate-like body also reaches the central portion perpendicular to the conveyance direction of the leaf-like body and a large suction force that is not significantly different from the suction force. It is intended to significantly reduce energy and noise compared to known transport devices.

  As a specific basic device, an appropriate number of intake devices and an appropriate number of intake members having an appropriate number of intake ports connected to the intake ports of the intake device through opening and closing members that can be opened and closed in a timely manner. An intake mechanism provided with the intake ports so that the intake ports of the intake member are arranged in a double row following the conveyance direction of the plate-like body, and at least the same number of conveyance belts as the number of the rows of the intake ports, A conveying mechanism provided with a regulating member that regulates the travel position of each conveying belt on the inner peripheral side of each conveying belt, and each conveying belt approaches at least one side of each row of the intake ports. A transport device that transports while sucking the plate-like body from the upper surface side, and has an appropriate width and a length corresponding to the length of the row of the intake ports. A plate-like suction assisting member having an air inlet row of each of the conveyor belts does not exist. Providing a space close to one side and at the same height as the restricting member, and between another suction assisting member or a row of air intakes located in the vicinity, enough to suck air from above. Thus, a plate-shaped conveyance device (claim 1) characterized by being arranged in a double row is proposed.

  Furthermore, as a suitable practical example, a plate-like material conveying device according to claim 1, further comprising a conveying mechanism in which a conveying belt and a suction assisting member are provided on both sides of each row of intake ports. ), The intake port of the intake member is divided into a plurality of compartments in the conveying direction of the plate-like body, and an opening / closing member is provided for each compartment to convey the plate-like body in accordance with the progress of the plate-like body. The plate-like body conveying device (claim 3) according to claim 1 or 2, wherein the opening / closing members are sequentially opened from the upper side to the lower side in the direction.

  According to the conveying device according to the first aspect, the suction assisting member is arranged in parallel on each of the conveyor belts, so that the suction action is extended over a wider range than when the suction assisting member is not juxtaposed and the air is sucked only by the intake member. Therefore, it is possible to generate a larger suction force than when suctioning only with the suction member, as well as a suction assisting member arranged in parallel with each conveyor belt, and another suction assisting member or intake air located nearby. Since there is sufficient space between the mouth row and the air to be easily sucked from above, intake air is also formed at the intermediate portion between the suction ports adjacent to each other in the direction perpendicular to the plate-shaped conveyance direction, Since the phenomenon of air stagnation in the intermediate portion is eliminated, even if the number of rows of intake ports is relatively small, a plate-like body can be sucked from the carry-in conveyor without any special trouble and adsorbed to the conveyor belt. And the plate surface is relatively Even when conveying a large plate-like body, a large suction force that does not greatly differ from the suction force acting on the four peripheral end portions of the plate-like body reaches the central portion in the direction orthogonal to the conveyance direction of the plate-like body, In general, the plate-like body can be stably sucked and conveyed by using a small number of intake members and a small-capacity intake device as compared with the conventional case.

  Furthermore, as described in claim 2, according to the configuration in which the conveyance belt and the suction auxiliary member are provided on both sides of each row of the intake ports, the suction force generated by the suction action of the suction member and the suction auxiliary member is The most effective use is beneficial because the plate-like body can be adsorbed to the conveyor belt. According to a third aspect of the present invention, inhalation by the intake port for each of the sections divided into a plurality of sections in the conveyance direction of the plate-like body is performed from the upper side to the lower side in the conveyance direction in accordance with the progress of the plate-like body. However, according to the configuration that starts sequentially, unnecessary intake is not required, so that the required capacity of the intake device can be remarkably reduced, which is extremely beneficial.

  Hereinafter, the present invention will be described in more detail together with an example of the embodiment illustrated in the drawings. However, the form of each member constituting the apparatus is not limited to the form of the illustrated example, and may be a form having a required function. If necessary, the shape of each member can be appropriately changed in design as needed. However, since the practical range is already known about the width of the row of the intake ports of the intake member, it should be mentioned in advance that if the width of the row of the intake ports is too small, the intake range Naturally, the range becomes narrow and the flow resistance of air during intake increases, so there is a tendency that the suction force cannot be exhibited effectively. On the contrary, when the amount is excessive, the front end side of the plate-like body is sucked. Since a large intake device is required for excessive intake of air, both are inappropriate and practically, it is preferably 50 mm to 250 mm, more preferably 100 mm to 200 mm. is there.

It is a cross-section part enlarged explanatory view in the YY line.

It has a trapezoidal opening and closing member 3h and the like, and obtains control of a control mechanism (not shown) so that the opening and closing member 3h is sequentially lowered from the upper side to the lower side in the conveying direction as the single plate 2 advances. Then, the fluid cylinder 3f is actuated and carried in via the carry-in conveyor 1. The single plate 2 is sequentially sucked from the front end side to the rear end side, and is adsorbed to a conveyance belt 4c of the conveyance mechanism 4 described later, and when the front end of the single plate 2 reaches a predetermined position, all the opening / closing members 3h are moved together. The fluid cylinder 3f operates to release the single plate 2 and the single plate 2 is dropped onto the floor plate 7 placed on the deposition table 6 to be described later.

  4 is a conveyance conveyor-like conveyance mechanism constituting the conveyance device for a plate-like body according to the present invention, and includes a rotating shaft 4a, a pulley 4b, a plurality of conveyance belts 4c, a regulating member 4d, and the like. The restricting member 4d for restricting the position of each conveyor belt 4c has a hole having the same diameter below the intake port 3b of the intake member 3a so as to have a part of the function of the intake member 3a. The conveying belts 4c are respectively disposed on both sides of each row of the air inlets 3b of the air intake member 3a. The thickness of the belt itself is the same as that of the regulating member 4d having a part of the function of the air intake member 3a. Each of them is disposed so as to protrude and is rotated in the direction of the arrow by a drive source (not shown) composed of a servo motor, an electric motor with a clutch and a brake, and the like by the intake mechanism 4. Transport bed The veneer 2 adsorbed to preparative 4c, conveyed in the direction of the arrow in FIG.

  Reference numeral 5 denotes a width W2 that is equal to or greater than the width W1 of the row of intake ports 3b of the intake member 3a (the illustrated example is substantially the same), and a length that corresponds to the length of the row of intake ports 3b of the intake member 3a. A plate-like suction assisting member having the same height as that of the regulating member 4d in the vicinity of one side where the row of the intake ports 3b of the respective conveyor belts 4c does not exist. The air is easily sucked from above with the suction assisting member 5 (or between the suction inlet row in the case where the conveying belt and the suction assisting member are present only on one side of the inlet row). Are arranged in a double row with a sufficient interval 5A, which helps to amplify the suction force associated with the intake action of the intake mechanism 3.

  6 is a stacking table having a carry-out conveyor 6a, which is controlled by a control mechanism (not shown), and is moved up and down in the direction of the arrow in a timely manner, and dropped from the plate-like material transport device according to the present invention. Are always received through the floor plate 7 with a substantially constant height and deposited, and whenever the deposition reaches a desired height, it is carried out to the left or right side via the carry-out conveyor 6a.

  Reference numeral 8 denotes a single plate detector composed of a reflection type phototube detector or the like, which detects the arrival of the front end of the single plate 2 carried in via the carry-in conveyor 1, and a control mechanism (not shown) The detection signal at the front end of the single plate, which is necessary for operating the fluid cylinder 3f of the intake mechanism 3 so as to sequentially lower the opening / closing member 3h from the upper side to the lower side in the transport direction as the travel proceeds, is not shown. Sends to the control mechanism.

  Reference numeral 9 denotes a single plate detector composed of a reflection type phototube detector or the like, which detects the arrival of the front end of the single plate 2 conveyed through the conveyance mechanism 4, and a control mechanism (not shown) A detection signal at the front end of the single plate necessary for operating the fluid cylinder 3f of the intake mechanism 3 is transmitted to a control mechanism (not shown) so as to raise 3h all at once. Based on the detection signal at the front end of the single plate transmitted by the single plate detector, the suction cylinder by the intake mechanism is turned off by operating the fluid cylinder of the intake mechanism so as to raise all the open / close members all at once. When the single plate is dropped, it is preferable to adopt a configuration controlled by a control mechanism (not shown) so that the conveyance of the single plate by the conveyance mechanism is suspended for a while, because the single plate drop position is further stabilized.

  The plate-shaped material conveying apparatus according to the present invention is configured as described above, for example. Hereinafter, the operation mode will be described with reference to the operation explanatory diagrams illustrated in FIGS. 4, when the front end of the single plate 2 carried in via the carry-in conveyor 1 arrives at the position of the single plate detector 8, the single plate detector 8 sends a detection signal of the single plate front end to a control mechanism (not shown). The control mechanism operates the fluid cylinder 3f of the intake mechanism 3 located on the uppermost side in the single plate conveyance direction to lower the opening / closing member 3h, and the intake air located on the uppermost side in the single plate conveyance direction. Since the intake port 3b of the member 3a is opened, as shown by the dotted arrow indicated by the symbol a in FIGS. 4 and 5, the lower side or the diagonal of the vicinity of the intake port of the intake member 3a mainly on the front end side of the single plate 2 Inhalation will be made from below, As shown by the dotted arrows in FIG. 1, intake air is also made from the sides of the left and right ends of the veneer 2 and the rear side near the intake port of the intake member 3a at the position facing the veneer 2 just before suction. As shown in FIG. 5, as indicated by the dotted line arrow c, intake air is also generated from the portion of the space 5 </ b> A provided between the adjacent suction assisting members 5.

  Then, due to the air flow as indicated by the dotted arrow indicated by the symbol a, the front end side of the single plate 2 is easily lifted upward, and the air pressure near the intake port of the intake member 3a on the front end side of the single plate 2 is increased. And the difference between the atmospheric pressure and the atmospheric pressure directly below the veneer 2 causes the front end of the veneer 2 to be sucked upward, and the conveyance belt of the conveyance mechanism 4 as illustrated in FIGS. 4c will be adsorbed. Then, the control mechanism (not shown) sequentially opens the intake port 3b of the intake member 3a by operating the fluid cylinder 3f from the upper side to the lower side in the transport direction in correspondence with the progress of the single plate 2. As illustrated in FIG. 8, the suction and the conveyance are continued as they are, but eventually the front end of the single plate 2 reaches the position of the single plate detector 9 and a single plate detection signal is transmitted from the single plate detector 9. Then, the control mechanism (not shown) operates all the fluid cylinders 3f to simultaneously close the intake ports 3b of the intake members 3a, so that the single plate 2 is released from suction / adsorption and falls toward the deposition table 6 To do.

  Thus, this kind of known transfer device is mainly configured as shown by the dotted arrow indicated by the symbol a, and the intake air from the lower side or the obliquely lower side near the intake port of the intake member on the front end side of the single plate, As shown by the dotted arrows shown in Fig. 2, with side air intake from the sides of the left and right ends of the veneer and the rear side near the intake port of the intake member at the position facing the veneer just before adsorption, Since the front end side of a single plate is sucked, in order to perform stable and reliable suction / adsorption, for example, the number of rows of intake ports is considerably increased, and the interval between the rows of intake ports is reduced. At the same time, it is necessary to provide an intake device having a capacity adapted to the total area of the intake port, or when the interval between the intake port rows is wide, the capacity of the intake device provided for each intake port row must be increased. However, as described above, the plate-like material conveying apparatus according to the present invention has a suction assisting member arranged in parallel on the conveying belt of the conveying mechanism. As indicated by the dotted arrow indicated by the reference symbol c, the intake air from the space provided between the adjacent suction assisting members is also utilized, so that generally a small number of intake members and a small capacity compared to the conventional case. It is possible to stably suck and convey the veneer using the intake air.

  Incidentally, although not shown as a comparative example, a test apparatus having a structure that is a combination of only the intake mechanism and the transport mechanism in the illustrated example, that is, a structure in which the attachment of the suction auxiliary member is completely omitted, is separately provided. As a result of assembling and experimenting, the number of rows of intake ports is about twice that of the illustrated example (5 to 6 rows), and the capacity of the intake device attached to each row is used in the illustrated example. The same function could not be achieved unless the capacity was substantially equal to the capacity of (total capacity was about twice).

  The above experimental results clearly prove the effectiveness of the suction assisting member. According to the structure composed of only the intake mechanism and the transport mechanism, the air pressure decreases with the intake of the intake mechanism, that is, the pressure reducing action. Is limited to a width slightly exceeding the width (W1 + W4 × 2) obtained by adding the width W4 of the conveyor belt to the width W1 of the row of intake ports (addition is doubled if present on both sides as in the illustrated example). However, when a suction assisting member is provided, the width W2 of the suction assisting member is further added (addition is doubled if present on both sides as in the illustrated example) (W1 + W4 × 2 + W2 × Since it is amplified to a degree slightly exceeding 2), a larger suction force (push-up force due to atmospheric pressure) is generated, and the single plate can be reliably sucked. However, if the width of the suction assisting member is too small, such suction assisting action is only slightly increased, and conversely, if the suction assisting member is excessively large, the decompression action itself is difficult to reach the full width, or the rows of the intake ports It is preferable to avoid an excess or an excess because the interval of the intake air is excessively wide, and it is preferable to avoid an excess or an excess. It was appropriate to set the width W2 of 1 to about 1 to 3 times.

  Further, as another comparative example, although not shown in the figure, the experiment was performed by closing the portion of the space 5A between the suction assisting members in the illustrated example so that the space was completely eliminated by using another plate material. However, if the capacity of the intake air used in the illustrated example is increased by about 100%, that is, if the intake air having about twice the capacity is not used, the same function cannot be achieved. The experimental results prove the utility of the interval, and according to the structure without the interval, the effect that the air pressure decreases with the intake of the intake mechanism, that is, the pressure reducing effect is compared from the row of intake ports. As a result, the suction force gradually decreases, and stable suction and adsorption cannot be achieved. In particular, the center of a single plate (plate-like body) There is a tendency for problems to occur easily in the portion.

  That is, in the series of operations described above, for example, at the central portion of the single plate 2 near the line YY in FIG. In principle, it is adsorbed to the conveyor belt 4d, but the intake air by the intake device is inferior in uniformity and hermeticity compared to the strong suction by the vacuum pump, for example, open or semi-open state. Intake port part, or for example, the suction port part that sucks the part where there is a gap between the conveyor belt and the single plate (plate-like body), and further, for example, cracks / chips in the single plate As the air is preferentially sucked from the portion of the air inlet that sucks the air gap portion, etc., if the state shown in FIG. As a result, a phenomenon in which air stays occurs, and the suction force tends to gradually decrease compared with the initial adsorption. Accordingly, for example, an abnormal situation in which the central portion of the single plate 2 is separated from the transport belt 4d of the transport mechanism 4 and falls downward due to warpage / abare of the single plate 2, fluctuation of the single plate's own weight, vibration, or the like. However, according to the structure having no gap, there is almost no room for air to flow into the portion of the corresponding inlet 3b except from the sides of the left and right ends of the single plate 2. As described above, it is difficult to prevent the fall by restoring the suction force, and there is a high possibility that the veneer falls as it is.

  On the other hand, when an interval is provided, when an abnormal situation occurs in which the central portion of the single plate 2 is separated from the transport belt 4d of the transport mechanism 4 and falls downward as illustrated in FIG. Since the air immediately flows in through the interval 5A as indicated by the arrow, the suction force is restored as in the initial stage of adsorption, the adsorption is restored to the state shown in FIG. 3, and the fall is prevented. However, if the width W3 of the interval 5A is too small, it is easy to inhibit the inflow of air, and conversely, if it is excessive, the interval between the rows of intake ports becomes excessively wide, so both are inappropriate. Therefore, it is preferable to avoid an excess or an excess. As a guideline, the width W3 of the interval 5A is ½ (half) to 1 times (equivalent to the width W1 of the row of inlets). ) Was appropriate.

  Thus, in order to most effectively utilize the suction force generated by the suction action of the suction member and the suction auxiliary member as described above, and to adsorb the plate-like body to the transport belt, as shown in the above-described example, It is appropriate to adopt a configuration in which a conveyance belt and a suction auxiliary member are provided on both sides of each row of intake ports, and a configuration in which a conveyance belt and a suction auxiliary member are provided only on one side of each row of intake ports is denied. Not a thing, but not a positive recommendation.

  Further, as shown in the illustrated example, the intake port of the intake member is divided into a plurality of compartments in the conveying direction of the plate-like body, and an opening / closing member is provided for each compartment, corresponding to the progress of the plate-like body. If the opening and closing members are sequentially opened from the upper side to the lower side in the conveying direction of the plate-like body, useless intake air is sucked when the front end side of the single plate (plate-like body) is sucked in sequence. Therefore, the required capacity of the intake air can be significantly reduced, which is extremely beneficial, and its utility is particularly remarkable when the width of the row of intake ports is 100 mm or more. Compared with the case where all the intake ports are left fully open from the beginning, the required capacity of the intake device can be reduced to a fraction.

  In the illustrated example, the intake member and the restricting member are formed integrally, and the restricting member has a part of the function of the intake member (intake port). The members may be provided separately as separate bodies, and if necessary, the structure may be a mixture of integral and separate bodies. Further, in the illustrated example, a plurality of funnel-shaped intake members are used in a line, but in this case, the intervals between the intake members are not necessarily close, as shown in the figure. There is a slight gap between the intake members, and even if the intake air at the slight gap is slightly incomplete, the single plate (plate-like body) in the middle of conveyance Since the inertia force in the same direction acts, there is no possibility that a special trouble will occur in the transport as long as the transport is performed at a relatively high transport speed.

  However, the shape of the intake member is not limited to a funnel shape, and is not shown. However, as in the illustrated example, as a method of separating into a plurality of rows and arranging them in a row, for example, a cylindrical shape, a quadrangular prism shape, an elliptical shape, etc. Various shapes including known shapes such as columnar and truncated pyramids can be adopted, and when adopting a method of separating the intake members into a plurality of rows in such a manner, as required In accordance with the aspect disclosed in Patent Document 2, the suction members arranged in the direction orthogonal to the conveyance direction of the plate-like body are connected with a suitably shaped ventilation pipe, and an opening / closing member is provided for each ventilation pipe. It is possible to take a form in which an air intake is attached, and although there is a problem that the required number of vent pipes and air intakes is increased, this is not a problem that causes a practical problem.

  On the other hand, in the case of adopting a configuration in which the width of the row of intake ports is relatively narrow, illustration is omitted, but a non-separable intake member having a long and narrow rectangular intake port, such as a dust hood of a wide sander, is adopted. However, even if the non-separation method is adopted, a partition is provided inside the intake port, and an opening / closing member is provided for each portion divided by the partition, corresponding to the progress of the plate-like body, It is desirable that the opening / closing member is sequentially opened from the upper side to the lower side in the conveying direction of the plate-like body.

  Further, the shape of the suction assisting member is basically a plate shape, but it does not restrict the attachment of a mounting tool, a reinforcing tool, etc., and is omitted from illustration, but for example, a plate shape such as a spherical flat steel shape is used. A shape in which an appropriately shaped reinforcing protrusion is provided on a portion other than the bottom surface of the main body, or a shape in which an appropriately shaped mounting arm is attached to a portion other than the bottom surface of the main body, etc. It suffices if the bottom portion facing the body is a smooth plate having an appropriate width and length, and the material is not necessarily the same as that of the regulating member. Various materials such as metal, synthetic resin, wood, etc. It is possible to use a material, and the attachment mode must be detachable except that it is attached to a position at the same height as the regulating member in the vicinity of one side where there is no row of inlets of the conveyor belt. There are no particular restrictions such as A is, a height including some tolerance, for example to be significantly inhibited the progression of the plate, slightly above the regulating member positioned below, no problem even lightly contacts the plate-like body. Furthermore, although not shown, if necessary, for example, in order to prevent vibration of the suction assisting member, an appropriate member is disposed in a part of the interval 5A, and adjacent suction assisting members are connected to each other. Even if it does, if it is a form which does not prevent the inhalation | air-intake from this space | interval remarkably, there will be no special trouble practically.

  In the example shown above, a plate-shaped member having a perforated intake port is used as the restricting member of the transport mechanism, and the transport belt is slidably supported. There is no problem even if the rollers (rollers) arranged in a row are used to support the rolling of the conveyor belt. Further, the conveyor belt of the conveyor mechanism has a rectangular shape with a simple cross section as shown in the above example. Although not shown, it is not limited to a common conveyor belt, but, for example, the front side is provided with a protrusion having an appropriate shape for increasing the friction coefficient against the plate-like body, or the back side, for example, It is possible to change the design appropriately as necessary, such as those that are provided with tooth-like projections that engage with teeth provided separately on the pulley.

  As can be seen from the above, the plate-like body conveying device according to the present invention can reduce the arrangement cost of the air intake mechanism and the consumption power cost by about half compared with this kind of known conveying device. In addition, because it also enables noise reduction, it is effective not only for the single plate shown in the previous illustration but also for conveying various plate-like objects such as metal thin plates, synthetic resin plates, glass plates, cardboard, etc. The utility value in the industry related to the plate-like body is extremely high.
