A pair of side rails 137 and 137, a front end rail 138, and a terminal guard rail 139, which are the sheet position regulating members for the circuit board, are provided in the sheet separation conveying device 130 for a circuit board. The side rails 137 and 137 are disposed on both sides in the sheet width direction Y of the circuit board 136 of the loading table 136, and are oriented in the width direction of the circuit board sheet which is crossed (orthogonal) with the transport direction X of the circuit board sheet 1 to be placed. Positioning on Y. The distal end guide plate 138 performs positioning in the longitudinal direction corresponding to the transport direction X of the circuit board sheet bundle 1. Furthermore, the terminal guard rail 139 performs the same rear end positioning in the longitudinal direction.

The side air nozzle 370 which is displayed on the side rails 137 and 137 of the second figure (the left inner side in the drawing) is ejected as a side end portion of the sheet for the circuit board 1 and blows out the side air. Ac (refer to Fig. 4) a separate air blowing means, and a second air ejecting means, which is an air ejecting means. As shown in Fig. 4, the side air nozzle 370 is connected to the side air blower 380 which is generated as side air which generates the side air Ac.

The sheet separation conveying device 130 for the circuit board of FIG. 2 and the floating holding conveyor device 160 of the third drawing include a driving roller 162, a driven roller 163, a conveying belt 161, and a negative pressure air chamber 310. The driving roller 162 is rotationally driven by the driving shaft 162a, and the driven roller 163 rotates with the conveying belt 161 that is driven to rotate by the driving roller 162. The conveyor belt 161 is an endless belt member having a plurality of suction holes that communicate with the negative pressure air chamber 310. The suction air chamber 310 is connected to the suction blower 390 shown in FIG. 4, and is sucked by the external suction blower 390 to maintain the negative pressure state, and sucks and sucks the uppermost circuit board sheet 1A by the suction holes of the conveyor belt 161. The suction blower 390 has a function as a suction air generating means for generating suction air.

The direction in which the air is ejected is opposite to the direction of the transport direction X, and may not necessarily be parallel. It is oblique.

The gas, that is, the air, also contains air that has been eliminated from static electricity or other gas that is used to separate the pieces of the circuit board and to be separated one by one. In particular, since the sheet for a circuit board containing the carbon fiber is not easily separated by the electrostatic interaction between the sheets for the circuit board in the laminated state, it is effective to eject the static electricity-eliminating air to the sheet bundle 1 for the circuit board in the laminated state.

As shown in FIG. 3 and FIG. 4, the floating nozzle 322 ejects the floating air Aa toward the front end portion (hereinafter also referred to as a front end portion) of the sheet bundle 1 for the circuit board, and the circuit board sheet is used for the circuit board.

The sheet separation/transport apparatus 130 for a circuit board shown in Fig. 6(a) ejects the floating air Aa from the air chamber 320 toward the tip end portion of the sheet bundle 1 for the circuit board mounted on the loading table 136, and uses the wind to The height of the conveyor belt 161 (the board holding portion for a circuit board) is floated.

Then, by the operation of the suction blower 390, the uppermost one of the sheet bundles 1 for the circuit board is held by the conveyor belt 161. The uppermost circuit board sheet 1A held on the conveyor belt 161 is not necessarily one piece, and the circuit board sheets may be held in close contact with each other. Therefore, the side air is sprayed by the side air nozzle 370 which is a separate air blowing means provided on the side rails 137, 137, and the circuit board sheet 1A held by the conveyance belt 161 is divided into one piece. Separation means that air is ejected from the side air to reduce the adhesion between the sheets for the circuit board, thereby facilitating easy separation.

Thereafter, the circuit board sheet 1A is transported to the next transport destination by the transport of the transport belt 161 (for example, the next step), and then necessary processing is performed.

Between the air chamber 320 and the sheet bundle 1 for the circuit board mounted on the uppermost portion The chip blocking member 177 for a circuit board is placed to prevent the uppermost circuit board sheet other than the circuit board 1A from being transported. In addition, the detection sensor 20 for detecting the height of the sheet for the circuit board is provided in order to keep the distance h between the uppermost position of the sheet for the circuit board and the sheet 161 to be reduced as the sheet for supplying the circuit board is constant. The detecting sensor 20 is a reflective type photo sensor.

Specifically, the sheet bundle 1 for a circuit board is mounted on the loading table 136 by an operator, and is set to match the sheet size of the circuit board, and the front end surface thereof is brought into contact with the front end guide plate 138 so as to be aligned as a reference surface. . Further, by operating the side rails 137 and 137 and the terminal guard rail 139, the side end faces and the rear end faces of the sheet bundle 1 for circuit boards are aligned. In addition, in the preparation step, for example, a robot or a dedicated device may be used instead of the operator's hand, and the loading operation of the circuit board sheet bundle 1 or the circuit board sheet size may be performed as described above.

When the chip supply command for the circuit board is sent from the control unit of the chip separation/transfer device 130 for the circuit board of Fig. 1, as shown in Fig. 6(b), the air chamber 320 of the air injection nozzle device 300 includes the side air. The nozzles 370 are separated by a blowing means. Then, the floating step of the first step of ejecting the air to the respective end portions of the sheet for the circuit board is started (step S2 of FIG. 5). The floating air Aa from the floating nozzle 322 of the air chamber 320 is ejected, and the side air Ac is ejected from the side air nozzle 370, so that the uppermost circuit board on the prepared loading table 136 is floated by the sheets 1A, 1B, 1C. . Thereby, the contact area of the uppermost circuit board sheets 1A, 1B, and 1C is changed.

At the same time, the holding step of the floating circuit board for the circuit as the second step (step S3 of FIG. 5) is started, and the air suction of the conveyor belt 161 starts. Thereby, the uppermost circuit board sheet 1A is floated, and as shown in FIG. 6(b), the uppermost circuit board sheet 1A is adhered. Hold on the conveyor belt 161.

Further, (ST) attached to the symbol of the conveyor belt 161 indicates that the conveyor belt 161 is in a stopped state.

The "separation step" of the step S4 in Fig. 5 is a step of separating the sheets for the circuit board held by the conveyor belt 161, and as described above, the separation air blowing means including the side air nozzles 370 is performed.

(2) Next, as shown in Fig. 6(c), the driving of the conveyance belt 161 is started, and the conveyance step of the sheet 1A for the circuit board held by the conveyance belt 161 is carried out (step S5 of Fig. 5).

Further, in Fig. 6(c), (AD) which is attached to the symbol of the conveyor belt 161 in parentheses indicates that it is in the rotational conveyance driving state.

(3) Next, as shown in Fig. 7(a), after the circuit board sheet 1A reaches the supply sensor 179, after a predetermined period of time elapses, the circuit board sheet 1A is separated from the conveyor belt 161, and then the rotation conveyance drive is stopped.

(4) Immediately after the sheet 1A for the circuit board is separated from the holding area of the conveyance belt 161, as shown in FIG. 7(b), the sheet 1A for the next circuit board is floated by air jet and held on the conveyance belt 161.

(5) The drive of the conveyance belt 161 is restarted in accordance with the set supply interval for the circuit board, and the supply of the circuit board sheet 1A is performed.

(6) Thereafter, by repeating the above-described FIGS. 6(b) to 7(b), the sheets for the circuit board are sequentially conveyed.

In the above-described sheet supply operation for the circuit board, the air volume of the air chamber 320, the air supply means for separation, and the suction blower 390 are not described. When the air volume of the air is fixed at a certain value, the amount of floating or separation of the sheets for the circuit board differs depending on the thickness, weight, or size of the sheet for mounting the circuit board.

For example, when the amount of floating of the sheet for a circuit board is small, no feeding (no supply) is caused, and if the sheet for the circuit board is excessively floated, the sheet for the circuit board is in close contact with each other. Multiple pieces of overlapping supply. Further, if the force of the suction blower 390 is small, the sheet for the circuit board cannot be conveyed satisfactorily, and this will not be fed.

Therefore, in order to properly supply the sheet for the circuit board, it is necessary to determine the match in advance. When the user or the operator selects a sheet for a circuit board to be supplied with a sheet for a circuit board, the user or the operator automatically selects the air volume of the sheet for the circuit board to be loaded. Then, the air volume is adjusted according to the load value of the blower.
