Description

Prepreg conveyor

The present invention relates to a prepreg transport device.

Conventionally, a prepreg conveying device capable of transporting a prepreg has been known (refer to, for example, Patent Document 1).

Patent Document 1 discloses a transport device that sucks a prepreg by vacuum suction by an adsorption member provided on a moving plate of an adsorption conveyor, and then removes the sucked prepreg and places it on the transport. A device that carries the transport on the empty rack provided with it.

When the laminated prepreg is adsorbed and transported, the powder of the prepreg occurs. Among these powders, there are powders which are originally produced in the prepreg processing before separation and transportation, or powders which are generated by hitting a fence or a guide during transportation. Such a powder contains a resin component or the like, and most of the powder melts and adheres to and becomes large due to the heat of the member, and causes a problem in the suction member.

More specifically, when a suction member for adsorption transport is used, for example, a fan or the like, even if the room temperature is about 20 to 25 ° C, a high temperature is formed around the fan drive unit. At this high temperature, the powder will melt and coalesce, and when the fan is turned off, a certain amount of agglomeration will be formed. The agglomeration of a certain size may cause an abnormality to the fan.

The composition of body separation and transportation. Further, the width gauge or the thickness of the prepreg is merely an example, and the specification or thickness other than the above range may of course be used (the same as the large gauge described later).

As shown in FIGS. 1 to 3, the prepreg conveying device 100 according to the first embodiment includes an air nozzle spraying device 300 as a floating device for floating the prepreg 1A, and an adsorption transport device 23 to be floated. The prepreg 1A is adsorbed, held, separated and transported.

The adsorption transport device 23 includes a main body frame 24, a drive motor 25, a rotary drive shaft 26, a drive roller 26a, a driven shaft 27, a driven roller 27a, a conveyor belt 28, a guide plate 29, a wind guide groove 31, a fan 32, and the like. .

The rotary drive shaft 26 is rotatably supported by the main body frame 24, and is rotationally driven by a drive motor 25, and the drive motor 25 is coupled to one end portion of the rotary drive shaft 26 by a driving force transmission means such as a belt or a pulley. A plurality of drive rollers 26a are fixed to the rotary drive shaft 26. A driven shaft 27 rotatably supported by the main body frame 24 is provided on the upstream side in the transport direction X of the rotary drive shaft 26. Further, a plurality of driven rollers 27a are supported by the driven shaft 27. A plurality of conveyor belts 28 are wound between the drive roller 26a and the driven roller 27a. The conveyor belt 28 is rotated by the drive motor 25 The drive is rotationally driven in the transport direction X.

Guide plates 29 are disposed on the inner side of the loops constituting the transport belts 28, and a plurality of transport belts 28 are supported on the guide plates 29. The guide plate 29 is formed with a plurality of openings 33 for generating an adsorption force to the prepreg 1A by sucking air through the openings when the fan 32 rotates.

The guide plate 29 and the upper side of the conveyor belt 28 are provided with an air guiding groove 31 for guiding the intake air Ad, and a fan 32 as a suction member-suction device for generating the intake air Ad for sucking the prepreg 1A. As shown in the figure, the fan 32 can use a multi-blade exhaust fan such as a centrifugal blower, and the fan 32 includes an air intake port 32a for sucking in the intake air Ad, and an air discharge port 32b for discharging the intake air Ad. The air guiding groove 31 is provided with a plurality of partition plates 34, and a vent 35 is formed between the partition plates 34. In Fig. 1, a symbol 40 indicated by a two-dot chain line indicates that the fan 32 is provided on the installation surface of the apparatus main body (the same applies to Fig. 4 which will be described later).

Centrifugal fans with multi-blade blades (sirocco fan) are small and inexpensive, especially when compared to axial flow fans The advantages. However, the fan 32 can also use an axial flow exhaust fan if it is not necessary to have the advantages of the multi-blade exhaust fan described above.

As shown in Fig. 2 and Fig. 3, the stacked prepreg 1 is formed by laminating a plurality of prepregs. In the prepreg conveying device 100, the stacked prepreg 1 is placed in a stacked state and placed on a loading table 136 as a bottom plate.

The loading table 136 is movable in the vertical direction Z by the elevating mechanism of the prepreg loading unit driving device. Furthermore, the prepreg transport device 100 includes a detecting sensor 20 as a prepreg detecting device for detecting the upper position of the stacked prepreg 1 and a prepreg position control device for controlling the lifting mechanism. Drive to control the upper position of the stack of prepregs 1. With this mechanism, when the upper surface of the stack of prepregs 1 on the loading table 136 is occupied by the predetermined height position detected by the sensor 20, the uppermost prepreg 1A can be separated by the action described later. And carry it out.

The prepreg conveying device 100 is provided with a pair of side fences (137, 137), a front end guide 138, and an end fence 139 of the prepreg position regulating member. The side fences 137 and 137 are disposed on both sides in the width direction Y of the loading table 136 for positioning the stacked prepreg 1 in the width direction Y intersecting (orthogonal) with the conveyance direction X. The front end guide 138 is for performing positioning of the front end in the longitudinal direction (corresponding to the transport direction X of the stacked prepreg 1). In addition, the end fence 139 Used to perform positioning of the back end of the same length direction.

The side air nozzle 370 shown by a broken line in Fig. 3 has a function as a second air ejecting member, and is used as a separate air blowing device that blows the side air Ac against the side end portion of the stack prepreg 1 - Air ejection device. As shown in FIG. 3, the side air nozzles 370 are disposed at the side fences 137, 137 and are connected to the side blower 380, which is used to generate the side air generating device or side of the side air Ac. The air is blown out of the device. The side blower 380 can use a multi-blade blower such as a centrifugal blower, or an axial flow blower.

An air nozzle ejecting device 300, which is also an air blowing device, is disposed at a position facing the front end of the stacked prepreg 1 to be loaded. The air nozzle spraying device 300 is provided with an air chamber 320 for storing a gas (hereinafter also referred to as air) pressurized by an external floating blower. Further, as shown in FIGS. 2 and 3, the air chamber 320 is provided with two floating nozzles 322.

As described above, the air nozzle spraying device 300 has a function as a floating device that floats the prepreg loaded on the loading table 136. Further, the air nozzle spraying device 300 has an air ejecting device that ejects air to the mounted prepreg to float the end portion of the prepreg, and a first air ejecting member that ejects air in a direction opposite to the transport direction X. The air which is a gas to be ejected also includes air which is subjected to static electricity removal or other gas which is used to float the prepreg and separate the prepreg. Since the prepreg in a stacked state is closely adhered to each other by electrostatic action, and it is difficult to separate, it is effective to spray the static electricity by blowing the stacked prepreg 1 in a stacked state.

As shown in Fig. 3, the floating nozzle 322 blows the floating air Aa toward the front end portion of the stacked prepreg 1, and floats the prepreg from the stacked prepreg 1. Further, if the blown air is warm air, in addition to the dehumidifying effect of the prepreg, the separation and separation of the prepreg can be performed more efficiently.

Next, the main operation steps of the prepreg conveying device 100 will be described.

(1) First, a preparation step of preparing a prepreg in a stacked state is performed. Specifically, the operator mounts the stacked prepreg 1 on the loading table 136, and, in order to fit the prepreg specification, the front end surface thereof touches the front end guide 138 and is aligned as a reference surface. . Next, the side fences 137 and 137 and the end fence 139 are operated to align the side end faces and the rear end faces of the stacked prepreg 1 respectively.

When the control unit of the prepreg transport device 100 receives the prepreg feed command, the air blower includes a floating blower of the air nozzle spray device 300 and a separate blower for the side blower. Will act. By this mechanism, the step of floating the air to the respective ends of the prepreg is started. The uppermost prepreg 1A, 1B, 1C prepared on the loading table 136 is floated by blowing the floating air Aa from the floating nozzle 322 of the air chamber 320 while blowing the side air Ac from the side air nozzle 370. . By this action, the contact area between the uppermost prepregs 1A, 1B, and 1C starts to change. At the same time, the holding step of holding the floating prepreg is started. By the operation of the blower 32, the air in the air guiding groove 31 is sucked, the flow of the intake air Ad is generated, and the inside of the air guiding groove 31 becomes a negative pressure, and air is sucked through the plurality of openings 33 of the guide plate 29. By this operation, the uppermost prepreg 1A is lifted up, and the uppermost prepreg 1A is adsorbed and held on the conveyance belt 28.

As described above, in the first embodiment, by applying the floating air Aa from the floating nozzle 322, the stacking prepreg 1 is uniformly applied with the wind pressure to suppress excessive floating or abnormal operation, and to prevent the initial stage of the blowing. The dip is transported in an overlapping manner. At the same time, the prepreg separation process held by the conveyor belt 28 is carried out by means of a separate air supply device including the side air nozzles 370.

(2) Next, the transport belt 28 is started to be driven to carry out the transport step of transporting the prepreg 1A held by the transport belt 28.

According to the above configuration, the prepreg 1A can be adsorbed and transported without slamming during transportation. Further, it is not necessary to push and transport the prepreg 1A by a transport roller or the like. When the pressing trace or the damage remains on the prepreg, when the electronic circuit board or the like is produced, the thickness is not uniform, and a problem in electrical resistance occurs, and such a prepreg cannot be used. The adsorption transport method of the first embodiment is suitable for the transportation problem specific to the material sheet used for the electronic circuit board and the circuit board sheet.

Here, the plate for a circuit board is a thin plate-shaped member, and means a sheet including a prepreg, and includes a plate for use in all conventional circuit boards in addition to an electronic circuit board.

In the conveyance of the prepreg 1A, the powder generated by the prepreg 1A hitting a fence or a guide or the like, or the powder which is originally generated during the prepreg processing before being separated and transported, is sucked from the opening 33, via ventilation. The port 35 is carried to the vicinity of the blower 32. Since the high temperature is formed in the vicinity of the fan 32, the prepreg powder is melted and coalesced, and when the fan is turned off and cooled, a certain amount of agglomeration is formed. The formation of a certain size of agglomerates has an abnormal effect on the blower 32.

Therefore, in the first embodiment, a temperature increase suppressing means is provided to suppress The temperature around the fan 32 rises without causing agglomeration of the prepreg described above. As an example of the temperature increase suppressing device, the heat sink 41 shown in Fig. 1(a) is attached to the installation surface 40 on which the blower 32 is provided. With the radiator 41, the temperature rise around the blower 32 can be suppressed. The radiator 41 is provided on the back side 42 opposite to the conveyance belt side 43 with the installation surface 40 of the blower 32 interposed therebetween.

The installation surface 40 belonging to the installation portion of the radiator 41 is substantially in the vicinity of the heat source generating portion. Specifically, as shown in Fig. 1(a), the fan motor rotating shaft portion 32c is rotatable around the fan 32. Or in the vicinity of the fan housing portion 32d.

As described above, according to the first embodiment, the temperature rise around the blower 32 can be suppressed by the radiator 41 provided on the installation surface 40 of the blower 32. Therefore, according to the first embodiment, the occurrence of powder agglomeration which occurs during the conveyance of the prepreg can be suppressed.

(Variation 1)

The prepreg conveying device according to the first modification of the first embodiment will be described with reference to Fig. 4 . Fig. 4 (a) is a schematic view showing an arrangement state of a conveyor belt, a fan, a mounting surface, and a radiator in the first modification, and Fig. 4 (b) is a schematic diagram showing a main part of the prepreg conveying device according to the first modification. Decompose the perspective view.

The prepreg transport device 100A according to the first modification shown in FIGS. 4(a) and 4(b) differs from the prepreg transport device 100 according to the first embodiment in that the adsorption transport device 23A is used. Instead of the adsorption transport device 23. Further, the adsorption transporting device 23A differs from the adsorption transporting device 23 in that a heat dissipating guide 44 is used instead of the heat sink 41. That is, as shown in Fig. 4(a), in the first modification, the heat dissipation guide 44 belonging to a heat dissipation guide member is provided as a temperature rise suppressing means on the installation surface 40 where the blower 32 is provided to suppress the periphery of the blower 32. The rise in temperature. The heat dissipation guide 44 penetrates the installation surface 40 of the fan 32, and a part of the heat dissipation guide 44 exposes the back side 42 of the installation surface 40, and the back side 42 is not provided with the conveyance belt 28. According to the above configuration, the heat that is warmed by the blower 32 can be dissipated to the space on the back side 42 by the heat dissipation guide 44. At this time, the closer the distance between the fan 32 and the heat dissipation guide 44 is, the more suitable it is to dissipate heat.

As described above, according to the first modification, the heat that is warmed by the blower 32 can be dissipated to the space on the back side 42 by the heat dissipation guide 44 provided through the installation surface 40 of the blower 32, so that the temperature around the blower 32 The rise is suppressed. Therefore, according to the modification 1, the case where the powder generated when the prepreg is transported becomes agglomerated can be suppressed.

Further, the adsorption transport device 23 of the first embodiment and the adsorption transport device 23A of the first modification are not limited to the above-described embodiments, and a plurality of intake air passage openings (suction holes) may be provided in the transport belt 28, and The configuration in which the opening 33 of the guide 29 is deleted. In the case of such a configuration, the dimension of the width direction Y of the transport belt 28 is preferably set to be larger than the width of the guide plate 29.

Each of the driven rollers 163a, 163b, and 163c is integrally formed on the same driven shaft 163s, and is disposed on the driven shaft 163s. The drive shaft 162s and the driven shaft 163s are rotatably supported by the body frame 101 by bearings.

As described above, as shown in FIGS. 7 and 8, the transport belt 161c located at the center in the width direction Y and the belt holding surfaces 161a and the transport belt 161b disposed on the outer sides of the transport belt 161c are oriented in the vertical direction. A step D is formed.

The drive shaft 162s is coupled to a drive motor 168 belonging to the belt drive device via a toothed pulley and a toothed belt belonging to the rotary conveyor. The conveyance belt 161a and the conveyance belt 161b are rotationally driven by the drive motor 168 via the drive rollers 162a and 162b. The conveyance belt 161c is rotationally driven by the driven rotational force of the driven drum 163c that is driven to rotate by the rotation of the conveyance belt 161a and the conveyance belt 161b. In this way, the transport belts 161a, 161b, 161c are rotated in the same rotational direction as indicated by arrows in Fig. 7 and at the same peripheral speed.

As shown in Figs. 8 to 10, the transport belts 161a, 161b, and 161c are formed with a plurality of suction holes 164 and formed in a form capable of holding the prepreg. Further, in Figs. 8 to 10, in the drawings of the transport belts 161a, 161b, and 161c, the suction holes 164 are depicted as being formed on a portion of the lower side of the belt body, but the suction holes 164 are formed in the transport belts 161a, 161b. The way 161c is on the entire circumference should be of course.

The negative pressure air chamber 310 is disposed on the inner side of the loop of the transport belts 161a, 161b, and 161c, and is open to Up and down direction Z. As shown in Fig. 5, the right end portion of the negative pressure air chamber 310 in the drawing is connected to the lower end portion in the drawing of the suction air guiding groove 311. In the drawing in which the air guiding groove 311 is sucked, the upper end portion of the negative pressure air chamber 310 is connected to the air suction port 32Aa of the fan 32A connected to the upstream side. The air discharge port 32Ab of the upstream side fan 32A communicates with the air suction port 32Ba connected to the adjacent downstream side fan 32B, and discharges the intake air Ad from the air discharge port 32Bb of the fan 32B. Compared with the fan 32 shown in Fig. 1, each of the fans 32A and 32B differs mainly in the shape of the air suction port and the air discharge port, and the static pressure type or the like is the same.

In this manner, for example, the upstream side fan 32A and the downstream side fan 32B constituted by the multi-blade fan are arranged in series. In this way, the static pressure-suction force can be increased, and the prepreg can be fully sucked-maintained and transported.

As shown in Fig. 9, by driving the upstream side fan 32A together with the downstream side fan 32B (hidden, invisible in Fig. 9), a flow of the intake air Ad is generated to cause the suction guide connected to the fan 32A. The air duct 311 and the negative pressure air chamber 310 connected to the suction air guiding groove 311 form a negative pressure. In this manner, the suction air Ad is drawn from the suction holes 164 of the transport belts 161a, 161b, and 161c, and the prepreg can be adsorbed and held by the belt holding faces of the respective transport belts 161a, 161b, and 161c.

As shown in Fig. 10, a holding area 166 for holding the prepreg in a transparent direction is formed in the width direction Y of the adsorption transport device 160. The holding area 166 is a region in which the plurality of suction holes 164 are formed in the conveyance belts 161a, 161b, and 161c.

Here, the floating step of the first embodiment which is substantially the same as the floating step described in the second embodiment (2) will be described. As shown in Fig. 2 and Fig. 3, when the floating air Aa is blown from the floating nozzle 322 of the air nozzle spraying device 300, and the side air Ac is blown from the side air nozzle 370, the prepreg is as The ground separation is shown in Fig. 11. By the intake air Ad from the belt holding surface of the divided center conveyance belt 161c, only the front end center portion 1Ac of the prepreg 1A is bent and deformed into a convex shape (reverse shape). Fig. 11 shows a state in which the distal end central portion 1Ac of the prepreg 1A is formed into a convex shape and is adsorbed and held by the transport belt 161c at the central step portion.

In the center sides 1Aa and 1Ab of the prepreg 1A corresponding to the center side conveyance belts 161a and 161b, the prepreg 1A is sucked and held by the suction air Ad from the belt holding surface along the step D of the belt holding surface. 1Aaa and 1Abb on both sides of the end portion leaving the holding surface portion are oriented toward the prepreg 1A The shape of the end drooping.

On the other hand, in the first prepreg 1A, since the holding surface formed by the adsorption transport device 160 disappears toward the rear end portion of the prepreg 1A, the prepreg 1A is substantially horizontal with respect to the tape holding surface. In addition, the prepreg 1A is swelled toward the center of the prepreg 1A by the inflow of the side air toward the rear end of the prepreg, and is turned up from the rear end portion of the prepreg 1A. Convex arched (semicircular).

As shown in Fig. 11, the floating form of the prepreg 1B and 1C after the second and subsequent steps is curved in a convex shape (reverse shape) due to the floating air and the side air, and As it approaches the end portions of both sides, it floats due to its own weight. The state of the floating separation shown in Fig. 11 is, for example, only an example in which the thickness of a material prepreg is 0.02 mm to 0.2 mm.

That is, although the type of material will also be affected, the thinner the thickness is to nearly 0.02 mm, the degree of the above-mentioned bending will be larger, and the thicker the thickness is to nearly 0.2 mm, the degree of the above-mentioned bending will be smaller to form a substantially horizontal state. Going up. Further, when the side air does not act, the prepregs 1B and 1C cannot float and remain in the same state as in the initial stage of loading.

In the above-described floating step, holding step, and separating step, in the separated state, a difference in shape occurs between the first prepreg 1A and the second prepreg 1B, and the prepreg is deformed toward the belt holding direction. , so that the prepregs are indeed separated from each other. Therefore, the overlapping conveyance of the prepreg can be surely prevented.

On the other hand, when the first prepreg 1A is transported, the first prepreg 1A is transported while maintaining the shape maintained by the belt holding force, and the transport shape of the first prepreg 1A is timed. The first prepreg 1A is continuously applied to the first prepreg 1A by the stress, and a state in which the prepreg is easily separated is formed. The prepreg which has been floated by the floating step has a shape in which the end portion is separated from the prepreg held by the holding step and the prepreg in the stacked state.

During the transport of the prepreg 1A by the adsorption transport device 160, the powder generated by hitting the fence or the guide or the like, or the powder originally generated during the prepreg processing before the separation and transport, from the transport belts 161a, 161b, and 161c The suction hole 164 is sucked together with the suction air Ad. The powder of the prepreg is not carried to the vicinity of the fan 32A and the fan 32B through the negative pressure air chamber 310 and the suction air guiding groove 311. At this time, if a high temperature is formed in the vicinity of the fan 32A and the fan 32B, the prepreg powder will When the melt is coalesced and the fan 32A and the fan 32B are closed and cooled, a certain size of agglomerates is formed. The formation of the agglomerates of a certain size causes an abnormality in the fan 32A and the fan 32B.

However, in the first embodiment, as shown in FIGS. 5 and 6, the heat sinks 41 and 41 are provided corresponding to the installation faces 40 on which the fans 32A and 32B are provided, respectively. As shown in the plan view of Fig. 6(a), the fans 32A and 32B are provided on the downstream side 47 of the transport direction X, and the heat sinks are disposed on the upstream side 46 of the transport direction X, with the installation faces 40 of the fans 32A and 32B interposed therebetween. 41, 41. With these heat sinks 41 and 41, the temperature rise around each of the fans 32A and 32B can be suppressed.

As described above, according to the first embodiment, the temperature rise around the respective fans 32A and 32B is suppressed by the heat radiators 41 and 41 provided on the installation surface 40 of each of the fans 32A and 32B. Therefore, according to the first embodiment, the occurrence of powder agglomeration during the conveyance of the prepreg can be suppressed.

Further, in the first embodiment, of course, the heat radiation guide 44 may be provided as the temperature increase suppressing means similar to that shown in Fig. 4, and the above-described effects can be achieved by suppressing an increase in temperature around the respective fans 32A, 32B.

In the adsorption transport device 160 of the first embodiment, the three transport belts 161 of the second embodiment to be described later, which do not cause a step, may be used instead of the lift separation performance as described above. Belts 161a, 161b, 161c.

(Example 2)

Only the adsorption transport device 160 of the embodiment 1 can not completely transport the adsorbed and held prepreg to the destination position (for example, to be transported further, or to change direction, etc.), in this case, There is a need to re-set the adsorption transport device. Therefore, in order to be able to transport the adsorbed and held prepreg to the destination position, the second embodiment in which the adsorption transport device is additionally provided has been created.

The 32D series are connected in series. The fans 32C, 32D are constituted by, for example, a multi-blade exhaust fan.

As described above, the adsorption transport device 160A does not adsorb and hold the prepreg against the gravity like the adsorption transport device 160, but receives the prepreg transported from the adsorption transport device 160 so as not to cause skew or Adsorption and transportation in a manner such as positional shift. In addition, adsorption transport The transport speed of the 160A is controlled to be slightly faster than the transport speed of the adsorption transport device 160.

The difference between the prepreg conveying device 100D including the plurality of adsorption holding units of the third embodiment of the present invention and the prepreg conveying device 100B of the first embodiment shown in Figs. 5 to 11 is a principal axis. Fig. 15 is a perspective view of the prepreg conveying device including the plurality of adsorption holding units of the third embodiment viewed obliquely from the right, and Fig. 16 is a perspective view of the dip conveying device viewed obliquely from the right. Fig. 17 is a perspective view showing the back side of the prepreg conveying device from the obliquely upper right side, and Fig. 18 is a schematic explanatory view showing the action of various air in the prepreg conveying device.

As shown in Figs. 15 and 16, the main difference between the prepreg conveying device 100D and the prepreg conveying device 100D of the first embodiment is that it is disposed in the width direction Y and three are provided by the first embodiment. The adsorption holding units 3A, 3B, and 3C are unitized by the adsorption transport device 160. That is, pre In the dip transporting apparatus 100D, the adsorption holding means 3A, 3B, and 3C are provided to be capable of separating and transporting a prepreg having a large size (for example, a lateral dimension of 700 mm and a longitudinal dimension of 700 mm). 15 to 17 show the state in which the air nozzle spraying device 300 shown in Figs. 5 and 6 is removed, and the air nozzle spraying device 300 is disposed in each of the adsorption holding units 3A, 3B, and 3C. .

The upper prepreg 1A, 1B, 1C prepared on the loading table 136 can be floated by the floating air Aa from the floating nozzle and the side air blowing from the side air nozzles at the same time. In this way, the contact area between the uppermost prepregs 1A, 1B, and 1C changes.

At the same time, the holding step of holding the floating prepreg will also begin. The intake air Ad can be generated by operating the respective fans 32A and 32B of the adsorption holding units 3A to 3C at all three locations.

When the components of the adsorption holding units 3A, 3B, and 3C are used in common, the number of parts and the cost can be reduced. Further, depending on the specifications of the prepreg, the adsorption holding units 3A, 3B, and 3C may be configured to be detachable or configured to be movable, or even to be disposed on the downstream side in the transport direction. Further, the adsorption holding units 3A, 3B, and 3C may be selectively driven in accordance with the specifications of the prepreg.

The shaft 261s is coupled to a drive motor 268 as a drive unit, and is driven to rotate by the drive motor 268 to rotate the suction roller 261 in a direction in which the prepreg is pulled out and transported. The opening and closing door 270 is a valve member that performs ON/OFF control of the flow of the intake air generated by the driving of the suction fan 280 from the downstream side negative pressure air chamber 263 and the suction drum 261.

The adsorption roller 261 is a roller-shaped adsorption rotating member in which a plurality of suction holes 264 are formed in the outer peripheral portion. A negative pressure air chamber 263 is provided inside the adsorption roller 261. The negative pressure air chamber 263 is communicated to the opening and closing door 270 with an air duct 235, and is connected to the suction fan 280 by an air duct 235. The suction roller 261 is provided with a suction hole 264 at an upper position facing the front end portion of the stacked prepreg 1 placed on the loading table 136 in a stacked state. In this manner, the adsorption roller 261 is communicated to the opening and closing door 270 via the air duct 235 connected to the negative pressure air chamber 263, and is connected to the suction fan 280. The suction roller 261 sucks air from the external suction fan 280 by the negative pressure air chamber 263 to maintain a negative pressure state, and sucks-adsorbs the uppermost prepreg 1A by the suction hole 264 of the adsorption roller 261.

As described above, the adsorption roller 261 of the adsorption transport device 260 has a holding device-retaining member that sucks and holds the floating prepreg with a negative pressure formed by sucking air, and holds the retained prepreg The function of the transported transport device is implemented.

Further, the adsorption transport device 260 may increase the specifications of the adsorption transport device 260 in accordance with the specifications of the prepreg.

The operation of the prepreg transport device 230 including the adsorption transport device 260 will be described below using Figs. 25 and 26 .

When the prepreg feed command is transmitted from the control unit of the prepreg conveying device 230 shown in Fig. 25, the loading table 136 is raised as indicated by the thick arrow in Fig. 25(a), and is at a predetermined position. stop. The predetermined position means that the uppermost prepreg 1A of the stack of prepregs 1 loaded on the loading table 136 is floated to a position where it can be adsorbed by the suction roller 261 as will be described later. At this time, the opening and closing door 270 is in a closed state.

Then, as shown in Fig. 25(b), the floating air Aa is sprayed from the floating nozzle of the air chamber to the front end surface of the stack of prepreg 1 mounted on the loading table 136 while the opening and closing door 270 is kept closed. Blow while blowing side air with side air nozzles. The prepreg 1A, 1B, and 1C on the upper portion of the loading table 136 are floated by the air flow to be sprayed, and the prepreg 1A of the uppermost stack of the prepreg 1 is floated up to the adsorption roller 261 (prepreg holding portion). The height is nearby. By raising the uppermost prepregs 1A, 1B, 1C placed on the loading table 136, the contact area between the uppermost prepregs 1A, 1B, 1C is changed (upward step).

Next, in a state where the opening and closing door 270 is closed, the suction fan 280 is activated and actuated to generate suction air and generate a negative pressure. Next, as shown in Fig. 25(c), the adsorption roller 261 is brought into a negative pressure state by opening the opening and closing door 270, and the uppermost prepreg 1A is sucked and held by the adsorption roller 261 (holding step).

At this time, the uppermost prepreg 1A held by the adsorption roller 261 is not limited to one sheet, and there may be cases where the plurality of prepregs are held in close contact with each other. Therefore, the side air is blown by the side air nozzle provided as the side air fence as the separate air blowing means, and the prepreg 1A held by the adsorption roller 261 is divided into a single sheet (separate processing step).

Then, as shown in Fig. 26(a), the adsorption holding roller 261 is rotationally driven in the direction of the arrow in the figure, and the pre-adsorbed body 1A which is suck-hold-separated can be transported to the downstream side of the transport direction X as a target transport destination. Shipping (shipping step).

By the feed sensor disposed downstream of the conveyance direction X of the prepreg conveyance device 230 to perform the prepreg arrival detection, it is sensed that the prepreg 1A has reached the target transportation destination, that is, as shown in FIG. (b) The opening and closing door 270 is closed to form an atmospheric pressure in the negative pressure air chamber 263.

After the predetermined time elapses, the prepreg 1A is separated from the adsorption roller 261, and the rotation conveyance drive of the adsorption roller 261 is stopped (Fig. 26(c)). Further, in the case where the prepreg is continuously conveyed, the operation of Fig. 26(a) is continuously performed.

According to the above configuration, in the prepreg conveying device 230 including the adsorption transport device 260, the prepreg 1A can be adsorbed and transported without causing a squeaking during transportation. Further, it is not necessary to push and transport the prepreg 1A by a transport roller or the like. When a trace or damage is formed on the prepreg, when the electronic circuit board or the like is formed from the prepreg, the thickness is not uniform and a problem in electrical resistance occurs, and such a prepreg is not used. For solving such electronic circuit base plates - The transport problem specific to the material sheet of the board for a circuit board is suitable for the adsorption transport of the above-described embodiment.

In the transport of the prepreg 1A, the powder generated from the prepreg 1A or the powder generated during the prepreg processing is sucked from the suction hole 264 of the adsorption drum 261 and passed through the negative pressure air. The chamber 263 and the air duct 235 reach the vicinity of the suction fan 280. Since the suction fan 280 is in a high temperature state, the prepreg powder is melted and agglomerated, and when the suction fan 280 is closed and cooled, a certain size of agglomeration is formed. This agglomeration of a certain size has an abnormal effect on the suction fan 280.

Therefore, in the above-described embodiment, in order to prevent the above-described prepreg from agglomerating, a temperature increase suppressing means for suppressing an increase in temperature around the suction fan 280 is provided. As an example of the temperature rise suppressing means, a design in which a heat sink or a heat dissipation guide is disposed in the same manner as described above can be employed. In the above-described embodiment, by adopting such a configuration, it is possible to suppress the occurrence of powder agglomeration during the conveyance of the prepreg.
