Arrows such as white lines shown as appropriate in each figure indicate the direction in which air enters and leaves each apparatus.

As shown in FIGS. 1 and 2, the circuit board sheet bundle 1 is formed by laminating a plurality of circuit board sheets. In the circuit board sheet separating and conveying apparatus 130, the circuit board sheet bundle 1 is stacked and arranged in a stacked state on a stacking board 136 serving as a bottom plate.
The circuit board sheet, which is an object to be separated and transported according to the present invention, is a thin plate-like member, and includes sheets used for all known circuit boards in addition to electronic circuit board materials. For example, a fibrous reinforcing material such as carbon fiber or glass cloth is impregnated with a thermosetting resin mixed with additives such as a curing agent and a colorant, and is heated or dried to be in a semi-cured state. Reinforced plastic molding material (prepreg) is included. Moreover, what processed copper foil, gold foil, etc. to the prepreg and the resin sheet etc. which do not contain a prepreg are also contained.

As an example of the width size of the circuit board sheet, a sheet of about 100 mm to 700 mm is used. The thickness is about 0.02 mm to 0.2 mm.
The width size and thickness of the circuit board sheet are merely examples, and it is needless to say that those having a width size and thickness outside the above range are used.
Here, the conveyance direction X corresponds to the conveyance direction of the circuit board sheet. The vertical direction Z corresponds to the stacking direction of the circuit board sheets. The width direction Y of the circuit board sheet corresponds to a direction orthogonal to the conveyance direction X of the circuit board sheet and the up-down direction Z which is the stacking direction of the circuit board sheets.

  The loading table 136 is also called a supply table, and functions as a preparation unit that prepares circuit board sheets in a stacked state. The stacking table 136 can be moved in the vertical direction Z by an elevating mechanism that is a circuit board sheet stacking unit driving unit. The circuit board sheet separating and conveying device 130 controls the drive of the detection sensor 20 shown in FIG. 3 that functions as a circuit board sheet detecting means for detecting the upper surface position of the circuit board sheet bundle 1 and the drive of the lifting mechanism. Circuit board sheet position control means for controlling the upper surface position of the sheet bundle 1 for use. As a result, when the upper surface of the circuit board sheet bundle 1 on the stacking table 136 occupies a predetermined height position detected by the detection sensor 20, the uppermost circuit board sheet 1A is separated through an operation described later. Then transported.

  The circuit board sheet separating and conveying apparatus 130 is provided with a pair of circuit board sheet position regulating members, side fences 137a and 137b, a front end guide plate 138, and an end fence 139. The side fences 137a and 137b are arranged on both sides in the width direction Y of the circuit board sheet of the stacking board 136, and the width of the circuit board sheet intersecting (orthogonal) with the conveyance direction X of the arranged circuit board sheet bundle 1 Positioning in the direction Y is performed. The side fences 137a and 137b are also contact members that come into contact with respective side end surfaces of the circuit board sheet bundle 1, and function as circuit board sheet width positioning means for positioning the circuit board sheets in the width direction Y. In addition, a side end surface part means that a side end surface and the side end edge connected to this are also included.

  The front end guide plate 138 positions the front end in the length direction corresponding to the conveyance direction X of the sheet bundle 1 for circuit boards. Further, the end fence 139 also positions the rear end in the length direction. The side fences 137 a and 137 b are configured to be movable in the width direction Y of the circuit board sheet according to the width size of the circuit board sheet bundle 1. The end fence 139 is configured to be movable in the conveying direction X of the circuit board sheet bundle 1 according to the length size of the circuit board sheet bundle 1.

  A side air nozzle 370 indicated by a two-dot chain line on one of the side fences 137a and 137b in FIG. 2 (left rear side in the figure) ejects side air Ac (see FIG. 4) to the side end of the circuit board sheet bundle 1. It functions as a second air jetting member that is a blower for blowfish and air jetting means. As shown in FIG. 4, the side air nozzle 370 is provided on both side fences 137a and 137b, and is connected to a side air generating means for generating side air Ac or a side blower 380 which is a side air blowing means. . As the side blower 380, for example, a sirocco fan that is a centrifugal blower is used, but an axial flow blower may be used.

  As shown in FIGS. 1 to 4, the floating holding and conveying device 160 constituting the circuit board sheet separating and conveying device 130 includes a driving roller 162, a driven roller 163, a conveying belt 161, a negative pressure air chamber 310, A suction blower 390. As shown in FIG. 2, the driving roller 162 is rotationally driven in the direction of the arrow in the drawing by a driving shaft 162s connected to a driving motor as a belt conveying means. The driven roller 163 is integrally formed with a driven shaft that is rotatably supported, and rotates in the direction of the arrow in the drawing along with the conveying belt 161 that rolls by driving of the driving roller 162. The conveyor belt 161 is an endless belt member provided with a number of suction holes communicating with the negative pressure air chamber 310. The negative pressure air chamber 310 is connected to a suction blower 390 via a suction duct, which will be described later. Air is sucked from an external suction blower 390 to maintain a negative pressure state. The substrate sheet 1A is sucked and adsorbed.

The suction blower 390 has a function as suction air generation means for generating suction air Ad. As the suction blower 390, for example, a sirocco fan that is a centrifugal blower is used, but an axial flow blower may be used. A centrifugal blower (sirocco fan) provided with a multiblade fan is small and inexpensive, and has an advantage that it is easy to obtain a large pressure increase in one stage and less noise than an axial blower.
As described above, the conveyance belt 161 of the levitation holding conveyance device 160 includes the holding means for attracting and holding and separating the floated circuit board sheet with the negative pressure by air suction, and the conveyance means for conveying the held circuit board sheet.

The levitation holding and conveying apparatus 160 may increase the size of the levitation holding and conveying apparatus 160 according to the size of the circuit board sheet.

  At a position facing the front end of the stacked circuit board sheet bundle 1, an air injection nozzle device 300 that is also an air blowing means is arranged. The air injection nozzle device 300 is provided with an air chamber 320 in which air (hereinafter, also referred to as air) that is pressurized gas from an external floating blower is sent and stored. As shown in FIGS. 3 and 4, the air chamber 320 is provided with two floating nozzles 322.

As described above, the air ejection nozzle device 300 functions as an air ejection unit / levitation unit that floats the end of the air ejection circuit board sheet onto the circuit board sheet loaded and prepared on the stacking table 136.
The air, which is a gas, includes air that has been neutralized and other gases that are used to float the circuit board sheets and separate them one by one. In particular, a circuit board sheet containing carbon fibers is not easily separated because the circuit board sheets in the laminated state are in close contact with each other due to the action of static electricity. It is effective to spray.

  As shown in FIG. 3, the floating nozzle 322 blows the floating air Aa toward the front end portion (hereinafter also referred to as a front end portion) of the circuit board sheet bundle 1, and from the electronic circuit board material bundle 1 to the circuit board use. Raise the sheet. The floating nozzle 322 also functions as a first air ejection member that floats and separates the circuit board sheet by ejecting air to the stacked circuit board sheet bundle in the direction opposite to the conveyance direction X. If the air to be blown out is warm air, a dehumidifying effect is added to the circuit board sheet, and the circuit board sheet can be more effectively separated and removed.

FIG. 5 is a diagram illustrating main steps performed by the circuit board sheet separating and conveying apparatus according to the embodiment. 6 and 7 are diagrams for explaining the operation transition of the circuit board sheet separating and conveying apparatus.
First, with reference to FIG. 6A, a supplementary explanation will be given on the configuration and operation of the above-described circuit board sheet separating and conveying apparatus 130. As shown in FIG. 6A, the circuit board sheet separating and conveying device 130 blows the floating air Aa from the air chamber 320 toward the front end surface of the circuit board sheet bundle 1 loaded on the stacking board 136. It is levitated to the height of the conveying belt 161 (circuit board sheet holding portion) by wind.

Then, by the operation of the suction blower 390, the circuit board sheet 1 </ b> A which is one of the uppermost surfaces of the circuit board sheet bundle 1 is held by the conveyance belt 161. The uppermost circuit board sheet 1A held on the conveyor belt 161 is not limited to a single sheet, and the circuit board sheets may be held in close contact with each other. Therefore, side air is blown by a side air nozzle 370 which is a blowing air blowing means provided on the side fences 137a and 137b, and the circuit board sheet 1A held on the conveyor belt 161 is separated into one sheet. Sabaki is to assist the separation by blowing out air from the side air, thereby reducing the adhesion between the circuit board sheets.
Thereafter, the circuit board sheet 1 </ b> A is conveyed to a target conveyance destination by conveyance of the conveyance belt 161, and then necessary processing is performed.

  A circuit board sheet retaining member 177 is disposed between the air chamber 320 and the circuit board sheet bundle 1 stacked on the uppermost portion, and circuit board sheets other than the uppermost circuit board sheet 1A are disposed. It is prevented from being conveyed. Further, a detection sensor 20 for detecting the height of the circuit board sheet is provided so that the distance h between the uppermost position of the circuit board sheet and the conveying belt 161 that is decreased by the supplied circuit board sheet is always constant. Is provided. The detection sensor 20 is a reflective photosensor. Based on the signal from the detection sensor 20, the stacking board 136 is raised and adjusted by the circuit board sheet stacking unit driving means (elevating mechanism).

  The circuit board sheet bundle 1 is aligned with the front end surface as a reference plane so as to match the circuit board sheet size on the stacking plate 136. Further, a feeding sensor 179 that detects the arrival of the circuit board sheet is provided downstream of the levitation holding conveyance device 160 in the conveyance direction X.

Next, operations and processes of the circuit board sheet separating and conveying apparatus 130 will be described in order.
(1) The preparatory process (step S1 of FIG. 5) which prepares the circuit board sheet in a stacked state is performed, for example, as follows. Specifically, the circuit board sheet bundle 1 is stacked on the stacking table 136 by the operator, and its front end surface is abutted against the front end guide plate 138 so as to be set according to the size of the circuit board sheet. Aligned as a surface. Further, by operating the side fences 137a and 137b and the end fence 139, the side end face and the rear end face of the circuit board sheet bundle 1 are aligned. In the preparation step, for example, instead of a human operator or the like, a robot or a dedicated device may perform the stacking operation of the circuit board sheet bundle 1 or the circuit board sheet size adjustment as described above. Good.

  When a circuit board sheet feeding command is received from the control unit of the circuit board sheet separating and conveying apparatus 130 in FIG. 1, as shown in FIG. 6B, the air chamber 320 and the side air nozzle 370 of the air injection nozzle apparatus 300 are turned on. Including mackerel air blowing means operates. And the floating process as a 1st process of blowing the air to each edge part of the sheet | seat for circuit boards is started (step S2 of FIG. 5). When the floating blower of the air chamber 320 and the side blower 380 of the side air nozzle 370 are operated, the floating air Aa from the floating nozzle 322 of the air chamber 320 is blown, and the side air Ac is blown from the side air nozzle 370. Accordingly, the contact areas of the uppermost circuit board sheets 1A, 1B, and 1C can be changed by floating the uppermost circuit board sheets 1A, 1B, and 1C on the prepared loading table 136.

At the same time, a holding step (step S3 in FIG. 5) as a second step of holding the floating circuit board sheet is started, and air suction by the transport belt 161 is started. As a result, the uppermost circuit board sheet 1A floats, and as shown in FIG. 6B, the uppermost circuit board sheet 1A is adsorbed and held on the conveyor belt 161.
In FIG. 6B, the reference numerals of the air chamber 320 and the conveyor belt 161 in parentheses (AD) indicate that the air chamber 320 is in the blowing drive state and the conveyor belt 161 is in the suction drive state. Yes. Further, (ST) in parentheses attached to the code of the conveyance belt 161 indicates that the conveyance belt 161 is in a stopped state.

  The “baking process” in step S4 of FIG. 5 is a process of handling the circuit board sheet held by the conveyor belt 161, and is performed by the blowing fan means including the side air nozzle 370.

(2) Next, as shown in FIG. 6C, the driving of the conveyor belt 161 is started, and a conveyance process as a third process of conveying the circuit board sheet 1A held by the conveyor belt 161 is performed. (Step S5 in FIG. 5).
In FIG. 6 (c) and FIG. 7 (a) described later, (DR) indicated in parentheses on the reference numeral of the conveyor belt 161 indicates that it is in the rotational conveyance drive state.

(3) Next, as shown in FIG. 7A, after the circuit board sheet 1A reaches the feed sensor 179, the circuit board sheet 1A has passed through the conveying belt 161 after a predetermined time has elapsed. Thereafter, the rotational conveyance drive of the conveyance belt 161 is stopped.
(4) Immediately after the circuit board sheet 1A passes through the holding region of the conveyance belt 161, the next circuit board sheet 1A is floated by air blowing and held by the conveyance belt 161, as shown in FIG. The

(5) The driving of the conveyor belt 161 is resumed according to the set circuit board sheet feeding interval, and the circuit board sheet 1A is fed.
(6) Thereafter, the circuit board sheets are sequentially conveyed by repeating the above-described FIG. 6B to FIG. 7B.

When the air flow rate is fixed at a certain value, the floating amount and the surface state of the circuit board sheet differ depending on the thickness, weight and size of the loaded circuit board sheet.
For example, if the floating amount of the circuit board sheet is small, it will lead to non-supply (non-feed), and conversely, if the circuit board sheet is too lifted, the circuit board sheet will adhere. It becomes a double feed. Moreover, if the force of the suction blower 390 is small, the circuit board sheet cannot be conveyed well, and this is not supplied.

  Therefore, in order to properly feed the circuit board sheet, the air volume according to the stacked circuit board sheet is determined in advance, and the user or operator selects the circuit board sheet to which the circuit board sheet is to be fed. If so, the air volume is automatically adjusted. The air volume is adjusted by the value of the blower duty.

By this drive motor 168, the conveyor belt 161a and the conveyor belt 161b are rotationally driven via the drive rollers 162a and 162b. The conveyor belt 161c is rotationally driven by a driven rotational force of a driven roller 163c that is driven to rotate as the conveyor belt 161a and the conveyor belt 161b are rotationally driven. As a result, the conveyor belts 161a, 161b, and 161c rotate and rotate at the same peripheral speed in the same rotational direction indicated by arrows in FIG.

  As shown in FIGS. 9 and 10, the conveying belts 161a, 161b, and 161c are formed with a large number of suction holes 164 to hold the electronic circuit board material. In FIGS. 9 and 10, the suction holes 164 are depicted as being formed in a part of the lower side in the drawings of the conveyor belts 161a, 161b, and 161c, but all of the conveyor belts 161a, 161b, and 161c are illustrated. Of course, it is formed over the lap.

As shown in FIG. 13, when the suction blower 390 is driven, a flow of suction air Ad is generated, and the suction duct 311 connected to the suction blower 390 and the negative pressure air chamber 310 connected to the suction duct 311 are negative pressure. become. As a result, the suction air Ad is sucked from the suction holes 164 of the transport belts 161a, 161b, and 161c, whereby the circuit board sheet is sucked and held on the belt holding surfaces of the transport belts 161a, 161b, and 161c.
As shown in FIG. 10, a transparent holding area 166 for holding the circuit board sheet is formed in the width direction Y of the circuit board sheet of the levitation holding conveyance device 160 </ b> A. The holding area 166 is an area where a number of suction holes 164 are formed in the transport belts 161a, 161b, and 161c.

  Here, the levitation process to the holding process described in the above (1) to (2) will be supplemented using FIG. Similarly to the embodiment shown in FIG. 3, when the floating air is blown from the floating nozzle of the air injection nozzle device and the side air is blown simultaneously from the side air nozzle, the circuit board sheet is floated and separated as shown in FIG. To do. By the suction air Ad from the belt holding surface of the divided central conveying belt 161c, the front end central portion 1Ac of the circuit board sheet 1A is curved and deformed into a convex shape (inverted U shape). FIG. 11 shows a state where the front end center portion 1Ac of the circuit board sheet 1A is attracted and held on the conveyance belt 161c at the center step portion in a convex shape.

  The central both sides 1Aa and 1Ab of the circuit board sheet 1A corresponding to the conveying belts 161a and 161b on both sides are held on the belt holding surface within the formation range of the belt holding surface by the suction air Ad from the belt holding surface. Then, both ends 1Aaa and 1Abb of the tip portion away from the belt holding surface have a shape that is sagging toward the end of the circuit board sheet 1A.

  On the other hand, the first circuit board sheet 1A has no holding surface by the floating holding and conveying device 160A toward the rear end portion of the circuit board sheet 1A, so that the circuit board sheet 1A can be It becomes almost horizontal. Further, the circuit board sheet 1A faces the rear end of the circuit board sheet, and maintains the floating form by the inflow of side air, so that the center part of the circuit board sheet 1A swells, and the rear end part of the circuit board sheet 1A When viewed from above, it changes to an upwardly convex arch shape (semicircular shape).

  As shown in FIG. 11, the second and subsequent circuit board sheets 1B and 1C are bent into a convex shape (inverted U shape) by the floating air and side air, with the center portion at the tip thereof being upwardly convex. It floats so that it hangs down under its own weight as it comes to both sides of the tip. The floating separation state shown in FIG. 11 is merely an example in which the thickness of a certain type of circuit board sheet is 0.02 mm to 0.2 mm. That is, although depending on the type of material, the degree of bending increases as the thickness approaches 0.02 mm and becomes thinner, and the degree of bending decreases as the thickness approaches 0.2 mm and rises in a substantially horizontal state. Become. When the side air stops working, the circuit board sheets 1B and 1C cannot float and are held in the same state as in the initial stage of stacking.

  In the above-described floating process, holding process, and buckling process, as a separated state, a difference in shape occurs between the first circuit board sheet 1A and the second circuit board sheet 1B, and the circuit in the belt holding direction. The circuit board sheets are reliably separated from each other by the deformation of the circuit board sheets. Therefore, the double feeding of the circuit board sheet can be reliably prevented.

  On the other hand, when the first circuit board sheet 1A is conveyed, the holding shape of the first circuit board sheet 1A is maintained by the belt holding force and the first circuit board sheet 1A is conveyed. The conveyance shape changes from moment to moment, and it becomes easy to separate the circuit board sheet by constantly applying stress to the first circuit board sheet 1A. The circuit board sheet after floating in the floating process was shaped in a direction away from the circuit board sheet held in the holding process and the laminated circuit board sheet.

  As shown in FIG. 12, in the levitation holding conveyance device 160A of the first embodiment, a step D is formed in the vertical direction Z between the conveyance belt 161c, the conveyance belt 161a, and the conveyance belt 161b. Accordingly, the circuit board sheet 1A is sucked and held along the step D of the belt holding surface at the central both sides 1Aa and 1Ab of the circuit board sheet 1A corresponding to the transport belts 161a and 161b. The width BL2 is narrower than the width BL1 of the sheet bundle 1 for circuit boards. Therefore, the circuit board sheet does not contact the side wall surfaces of the circuit board sheet 1A with the inner wall surfaces of the side fences 137a and 137b, and the side fences 137a and 137b are not shaved.

  As described above, in the first embodiment, the side fences 137a and 137b are not shaved, but the locations where the side fences 137a and 137b are shaved will be described with reference to FIG. FIG. 13 is a side view for explaining a side fence occurrence portion.

16 and FIG. 17, in place of the circuit board sheet separating and conveying apparatus 130 as compared with the circuit board sheet separating and conveying apparatus 130 of the embodiment examples such as FIGS. 1 to 4, The difference is that the circuit board sheet separating and conveying device 230 is used.
The circuit board sheet separating / conveying device 230 controls the driving of the detection sensor 20 and the lifting mechanism similar to those of the circuit board sheet separating / conveying device 130 of FIGS. Although a circuit board sheet position control means and a front end guide plate 138 to be controlled are provided, they are not shown in FIG. The circuit board sheet separating and conveying apparatus 230 includes a pair of side fences 137, end fences 139, side air nozzles 370, and side blowers 380, similar to the circuit board sheet separating and conveying apparatus 130. FIG. However, illustration is abbreviate | omitted. Similarly, the circuit board sheet separating and conveying apparatus 230 includes an air injection nozzle apparatus 300 having an air chamber 320 and a floating nozzle 322, which is the same as the circuit board sheet separating and conveying apparatus 130, but is illustrated in FIG. Is omitted.

  The circuit board sheet separating and conveying apparatus 230 shown in FIGS. 16 and 17 is different from the circuit board sheet separating and conveying apparatus 130 in place of the floating holding and conveying apparatus 160 shown in FIGS. The difference is that 260 is used. The levitation holding and conveying device 260 is mainly different from the levitation holding and conveying device 160 shown in FIGS. 1 to 4 in that a suction roller 261 shown in FIGS. 16 and 17 is used instead of the conveying belt 161. Hereinafter, a detailed configuration of the levitation holding and conveying apparatus 260 different from the levitation holding and conveying apparatus 160 will be described.

As shown in FIGS. 16 and 17, the levitation holding conveyance device 260 includes a suction roller 261, a negative pressure air chamber 263, a shutter 270, an air pipe 235 that is a suction duct, and suction air generation means that generates suction air. As a suction fan 280. The suction fan 280 is not limited to this, and suction air generation means such as an air compressor may be used.
The suction roller 261 has a shaft 261s rotatably supported on the main body frame. The shaft 261s is connected to a drive motor 268 as a drive unit, and the suction roller 261 rotates in a direction in which the circuit board sheet is fed out and conveyed by the rotational drive of the drive motor 268.
The shutter 270 is a valve member that performs on / off control of flowing suction air generated by driving the suction fan 280 to the negative pressure air chamber 263 and the suction roller 261 on the downstream side.

  The suction roller 261 is a roller-like suction rotation member in which a large number of suction holes 264 are formed on the outer periphery. A negative pressure air chamber 263 is provided inside the suction roller 261. The negative pressure air chamber 263 communicates with the shutter 270 through a telescopic / flexible air pipe 235, and communicates with and is connected to the suction fan 280 through the air pipe 235. In the suction roller 261, the suction hole 264 is disposed at an upper position facing the front end portion of the sheet bundle 1 for circuit boards stacked in a stacked state on the stacking table 136. Thus, the suction roller 261 communicates with the shutter 270 via the air pipe 235 connected to the negative pressure air chamber 263 and is connected to the suction fan 280. The suction roller 261 sucks and sucks the uppermost circuit board sheet 1 </ b> A through the suction hole 264 of the suction roller 261 when the negative pressure air chamber 263 is sucked air from the external suction fan 280 and maintains a negative pressure state. .

As described above, the suction roller 261 of the levitating holding and conveying device 260 conveys the held circuit board sheet, the holding means / holding member that holds and separates the floated circuit board sheet by sucking with negative pressure by air suction. It has a function as a conveying means.
The levitation holding and conveying device 260 may increase the size of the levitation holding and conveying device 260 according to the size of the circuit board sheet.

The operation of the circuit board sheet separating / conveying device 230 provided with the levitation holding / conveying device 260 will be described with reference to FIGS. 18 and 19.
When a circuit board sheet feeding command is received from the control unit provided in the circuit board sheet separating / conveying device 230 in FIG. 18, as shown by a thick arrow in FIG. Stop in place. The predetermined position is a position at which the uppermost circuit board sheet 1A of the circuit board sheet bundle 1 loaded on the stacking board 136 floats and can be sucked by the suction roller 261 as described later. At this time, the shutter 270 is closed.
Next, as shown in FIG. 18B, the flying air Aa is blown from the floating nozzle of the air chamber toward the front end surface of the sheet bundle 1 for circuit boards loaded on the stacking table 136, and at the same time, the side air nozzles Blow air. This wind causes the circuit board sheets 1A, 1B, and 1C on the top of the stacking board 136 to float, and the uppermost circuit board sheet 1A of the circuit board sheet bundle 1 is attracted by a suction roller 261 (circuit board sheet holding unit). Ascend to near the height of. The contact areas of the uppermost circuit board sheets 1A, 1B, and 1C can be changed by floating the uppermost circuit board sheets 1A, 1B, and 1C on the prepared loading table 136 (the floating process).

Then, the suction fan 280 is activated and operated while the shutter 270 is closed to generate suction air to generate negative pressure. Next, as shown in FIG. 18C, the suction roller 261 is brought into a negative pressure state by opening the shutter 270, and the uppermost circuit board sheet 1A is sucked and held by the suction roller 261 (holding step).
At this time, the uppermost circuit board sheet 1A held by the suction roller 261 is not limited to one sheet, and may be held in a state where the circuit board sheets are in close contact with each other. Therefore, side air is blown by a side air nozzle, which is a blower means for suckling provided on the side fence, and the circuit board sheet 1A held on the suction roller 261 is separated into one sheet (baking step).

Thereafter, as shown in FIG. 19A, the suction roller 261 is rotationally driven in the direction of the arrow in the drawing, so that the circuit board sheet 1A that has been suction-held and separated is intended to be transported downstream in the transport direction X. It is conveyed ahead (conveyance process).
It is determined that the circuit board sheet 1A has reached the target conveyance destination by a feed sensor that detects the arrival of the circuit board sheet provided downstream in the conveyance direction X of the circuit board sheet separating and conveying apparatus 230. Then, as shown in FIG. 19B, the shutter 270 is closed, and the inside of the negative pressure air chamber 263 is set to atmospheric pressure.
After the predetermined time elapses, the circuit board sheet 1A passes through the suction roller 261, and then the rotation conveyance drive of the suction roller 261 is stopped (FIG. 19C). In addition, when conveying a circuit board sheet | seat continuously, operation | movement of Fig.19 (a) will continue.

  When the air flow rate is fixed at a certain value, the floating amount and the surface state of the circuit board sheet differ depending on the thickness, weight and size of the loaded circuit board sheet. For example, if the floating amount of the circuit board sheet is small, it will lead to non-supply (non-feed), and conversely, if the circuit board sheet is too lifted, the circuit board sheet will adhere. It becomes a double feed. Also, if the force of the suction fan 280 is small, the circuit board sheet cannot be conveyed well, and this is also not supplied.

  Therefore, in order to properly feed the circuit board sheet, the air volume according to the stacked circuit board sheet is determined in advance, and the user or operator selects the circuit board sheet to which the circuit board sheet is to be fed. If so, the air volume is automatically adjusted. The air volume is adjusted by the value of the blower duty.

  As described above, also in the circuit board sheet separating and conveying apparatus 230 according to another embodiment using the suction roller 261 and the like, the same problem as in the above embodiment can be solved and the same effect can be obtained. Can do.

  Also, in the circuit board sheet separating and conveying apparatus 230, as in the first and second embodiments, the floating holding and conveying apparatus 260 is arranged as a plurality of units in the width direction or the conveying direction according to the size of the circuit board sheet. To do. And the effect similar to Embodiment 1 and 2 can also be acquired by enabling the change of the position or making it removable.
