In FIG. 1, a transport line 2 on which a game board 1 is mounted and transported in a transport direction X is formed on a pair of conveyor frames 2a which are opposed to each other at a predetermined interval in a front-rear direction orthogonal to the transport direction X of the game board 1. It is formed on a roller conveyor in which a plurality of rollers 2b are arranged in parallel in the transport direction X. A defective discharge space 3 having a flat area in which only one game substrate 1 can be taken in the transfer posture is formed in the transfer line 2. Actually, the transport line 2 is divided at an intermediate portion in the transport direction X, and the divided upstream and downstream line components are separated from each other in the transport direction X, and a defective discharge space is formed between the line components. 3, for simplicity, only the upstream line components are shown as the transport line 2 in FIG. 1 and the downstream line components are omitted in FIG. The apparatus main body 4 is arranged in the defective discharge space 3 so as not to interfere with the game board 1 carried out from the transport line 2.

The apparatus main body 4 is provided with a pair of transport mechanisms 5 facing each other at a predetermined interval in the front-rear direction. Each transport mechanism 5 has a plurality of rollers 5c arranged in a row in the transport direction X inside a movable plate 5b that moves forward and backward in the front-rear direction crossing the transport direction X by an actuator 5a such as an air cylinder attached to the apparatus main body 4. , Which is rotatably mounted, and a shaft (not shown) supporting each roller 5c on the movable plate 5b is connected to a driven pulley 5d coupled to a rear end protruding outward from the movable plate 5b and the apparatus main body 4 (not shown). An endless belt 5g is stretched over a drive pulley 5f connected to an output end of a motor 5e attached through the stay.

In the transport mechanism 5 of this embodiment, when an inspection device (not shown) provided on the upstream side of the defective discharge space 3 does not detect defects such as the outer dimensions, thickness, squareness, and warpage of the game board 1. In a state where the pair of movable plates 5b are stopped at the forward limit position where they approach each other, and the plurality of rollers 5c are driven to rotate in one direction by the motor 5e, each roller 5c is moved from the transport line 2 to the defective discharge space 3. The unloaded game board 1 is transported in the transport direction X and transported to a downstream transport line (not shown). The inner surface of the movable plate 5b protruding above each roller 5c is formed as a guide portion for accurately guiding the game board 1 conveyed by the rollers 5c in the conveying direction X.

The inspection device (not shown) detects a defect in the game board 1, and when the game board 1 detected as a defect reaches the defective discharge space 3, the pair of movable plates 5b are moved to the retreat limit position where they are separated from each other.

The game board 1 is dropped during the period.

A pair of substrate stoppers 6 are disposed downstream of the defective discharge space 3 in the transport direction X at predetermined intervals in the front-rear direction. The substrate stopper 6 is provided so as to be able to advance and retreat in the same direction as the roller 5c of the transport mechanism 5 by an actuator 6a such as an air cylinder attached to the apparatus main body 4. While the inspection device (not shown) does not detect a defect in the game board 1, the board stopper 6 is located at the retreat limit position so as to retreat from the transfer path of the game board 1 formed by the upper transfer section of the roller 5 c in the transfer mechanism 5. It is stopped, and the function of the transport mechanism 5 for transporting the game substrate 1 in the transport direction X is continued. The inspection device (not shown) detects a defect of the game board 1, and when the game board 1 detected as a defect reaches the defective discharge space 3, the board stopper 6 advances from the retreat limit position and moves by the transport mechanism 5. By stopping at the forward limit position so as to protrude above the transport path of the game board 1 to be transported, the transport of the game board 1 is forcibly stopped.

In the defective discharge space 3 in the transport direction X
A delivery mechanism 7 is provided downstream and in the front-rear direction. That is, the delivery mechanism 7 is provided corresponding to each of the four corners of the defective discharge space 3. The delivery mechanism 7 corrects the falling posture of the game substrate 1 that falls from between the transport mechanisms 5 by retreating the movable plate 5b into a horizontal plane similar to the transport attitude of the transport line 2 and the transport mechanism 5. A receiver 7b provided to be able to advance and retreat in the same direction as the roller 5c of the transport mechanism 5 by an actuator 7a such as an air cylinder attached to the main body 4, and a casing such as an actuator 7a near each receiver 7b. And an abutment rod 7c attached to the stationary part.

The vertical piece of the receiving body 7b closely approaches the front and rear side surfaces of the game board 1. After the movable board 5b of the transport mechanism 5 retreats and the game substrate 1 that falls from between the rollers 5c is mounted on a horizontal piece of the receiver 7b, the receiver 7
When b stops at the retreat limit position, the interval between the horizontal pieces of the receivers 7b facing each other in the front-rear direction is set to be larger than the width of the game board 1, and the receivers 7b facing each other in the front-rear directions are set. The game board 1 falls from between.

The leading end of each abutting rod 7c is located at the notch 5h of the movable plate 5b stopped at the forward limit position of the transport mechanism 5.
The movable plate 5 is positioned so as to be closely opposed to the front and rear side surfaces of the game board 1.
It is located substantially flush with the inner surface of b, so that it does not interfere with the game board 1 transported by the transport mechanism 5. or,
The tip of each abutting rod 7c protrudes inward from the notch 5h of the movable plate 5b when the transport mechanism 5 stops at the retreat limit position, and when the receiver 7b stops at the retreat limit position, the game board 1 The game board 1 is accurately dropped in a horizontal plane without tilting while preventing the game board 1 from being accompanied by the receiver 7b.

In the defective discharge space 3, a discharge mechanism 8 is provided below the transport mechanism 5. The discharging mechanism 8 discharges the game board 1 dropped from between the transport mechanism 5 and the delivery mechanism 7 to the outside of the apparatus. In this embodiment, the lifter stacks a large number of the dropped game boards 1 to form a block. 9 and a transfer unit 10 for transferring blocks from the lifter 9 to the transport trolley 11. Lifter 9
Performs forward / backward movement of the substrate stopper 6, backward / forward movement of the transport mechanism 5 and forward / backward movement of the transfer mechanism 7 each time a defect is detected, so that the dropped game boards 1 are stacked from bottom to top each time they are received. At the same time, each time one game board 1 is stacked, the game board 1 descends by the thickness of one sheet, and the next falling game board 1 is dropped by a predetermined distance as small as possible, and the uppermost game board 1 on the lifter 9 is dropped. It is designed to be stacked on top.

The lifter 9 has a lift base 9a that can be moved up and down and transported. The lift base 9a is lifted and lowered via a bolt / nut mechanism 9c by an actuator 9b such as a motor mounted on the back of the apparatus main body 4 located behind the defective discharge space 3, and stands on the back of the apparatus main body 4. Lateral run-out is prevented by a guide mechanism 9d such as a cross roller composed of the left and right guide rails and a slider fixed to the lift base 9a in sliding contact with these guide rails. The lift base 9a is the game board 1
And a plurality of rollers 9e for transporting the block B in the discharge direction Y forward of the apparatus main body 4 intersecting with the transport direction X. Some of these rollers 9e are formed as motor rollers that rotate in the discharge direction Y by electromagnetic action such as a motor, and the remaining rollers 9e are free rollers that rotate freely. Multiple rollers 9
At both ends in the axial direction of e, the lift base 9a is provided with left and right guide plates 9f. Each guide plate 9f accurately guides the block of the game substrate 1 conveyed by the roller 9e in the discharge direction Y.

The transfer unit 10 includes a seesaw 10 a attached to a lower part of the apparatus main body 4. Seesaw 10
Reference numeral a denotes an actuator 10b such as an air cylinder attached to the apparatus main body 4, which swings up and down around a shaft member 10c. A drive roller 10d, a free roller 10e, a stopper 10f, and a sensor 10g are provided at a distal end of the seesaw 10a protruding outward from the inside of the apparatus main body 4.

A block in which a predetermined number of game boards 1 are stacked is formed on the lifter 9 of this embodiment. When the lift base 9a reaches the lower limit position, the tip of the seesaw 10a rises to the upper limit position indicated by the solid line. Then, the drive roller 10 d is driven to rotate in the same direction at the same speed as the roller 9 e of the lifter 9, so that the block of the game substrate 1 is driven from the lifter 9 via the relief roller 12 attached to the apparatus main body 4. 10d and the free roller 10e. At or before the block comes into contact with the stopper 10f, the rotation of the drive roller is stopped, and the operator is informed that the block of the game board 1 has been carried out of the apparatus by the block discharge completion notification display means (not shown). Inform

In response to this notification, the operator inserts the transport vehicle 11 into a space formed below the tip of the seesaw 10a at the ascending limit position, and the sensor 10g detects the transport vehicle 11 using the transport vehicle 11. Then, after the striker (not shown) fixes the position of the transport trolley 11 to the apparatus main body 4, the tip of the seesaw 10a descends from the upper limit position to the lower limit position. During this lowering, the block of the game board 1 on which the seesaw 10a is mounted at the tip is mounted on the loading section 11a
Hand over to

Reference numeral 13 in FIG. 1 denotes a substrate guide which is vertically attached to the apparatus main body 4 downward from the side of the transport mechanism 5 behind the lift base 9a, and the substrate guide 13 is provided on the lift base 9a. Prevents the blocks of the game board 1 from collapsing when descending. In FIG. 1, a low-profile board guide (not shown) is provided on the front side of the apparatus main body 4 corresponding to the board guide 13.
Are guided by the delivery mechanism 7 to drop the game board 1 between them horizontally, and the game board 1 is mounted on the lift base 9a.

The operation of this embodiment will be described with reference to FIGS. When the movable plate 5b of the transport mechanism 5 is stopped at the forward limit position and the game board 1 is transported from the transport line 2 through the transport mechanism 5 in the transport direction X, a defect detection (not shown) is performed. The device outputs a defect detection signal, and the game board 1 which is determined to be defective from which the defect detection signal is output is placed on the roller 5 along the movable plate 5b.
When the game board 1 arrives at the defective discharge space 3 as shown in FIG. 2, the game board 1 comes into contact with the board stopper 6 protruding on the transfer path, and the transfer of the game board 1 is regulated, as shown in FIG.

Next, as shown in FIG. 3, the receiving plate 7b of the delivery mechanism 7 moves forward and sinks below the front and rear direction of the game board 1 on the roller 5c.

Thereafter, as shown in FIG. 4, the movable plate 5b retreats, the roller 5c escapes from the game board 1, and the game board 1 is supported by the receiver 7b.

Subsequently, as shown in FIG. 5, the receiver 7b is retracted. At the time of retreat, the abutting rod 7c corresponds to the front and rear side surface of the game board 1, so that even if the game board 1 tries to accompany the receiver 7b, the game board 1 abuts on the abutting rod 7c. In this way, the game board 1 is prevented from tailgating, and the game board 1 falls from the receiving plate 7b while maintaining a horizontal plane from the solid line to the virtual line shown in FIG. Roller 9 of lift base 9a stopped at the receiving position
e. The receiving position of this lift base 9a is
When the gaming board 1 has already been mounted on the lift base 9a, the game board 1 at the uppermost stage at that time is close to the game board 1 mounted on the receiving plate 7b of the delivery mechanism 7 and is close to a certain distance. Each time a game board 1 that has been determined to be defective is ejected so as to be positioned, the rotation is controlled by the rotation amount of the motor 9b taking into account the thickness of one game board 1.
The board stopper 6 shown in FIG. 3 does not hinder the traffic of the normal game board 1 if the normal game board 1 retreats after stopping the game board 1 until the next normal game board 1 comes to the defective discharge space 3. For example, the game board 1 that has been determined to be defective is
If it is retracted after dropping from b to the lift base 9a,
The defective game board 1 is moved from the receiver 7b to the lift base 9a.
When the game board 1 falls, the board stopper 6 functions as a positioning, and the game board 1 can be accurately stacked on the lift base 9a.

Then, as shown in FIG. 6, the lift base 9a receiving the game board 1 is lowered to the retreat position. In the retreat position, the game board 1 mounted on the lift base 9a and indicated by a solid line and detected as a defect does not interfere with the transport mechanism 5 or the delivery mechanism 7. During the lowering of the lift base 9a, the game board 1 is guided by the board guide 13 so as not to collapse. The retreat position of the lift base 9a is such that, when the game board 1 is already mounted, the uppermost game board 1 at that time is transferred to the transport mechanism 5
Each time a defective ejection operation of the game substrate 1 is performed,
It is controlled by the rotational drive amount of the motor 9b taking into account the thickness of one game board 1.

Thereafter, the movable plate 5b of the transfer mechanism 5 stops at the forward limit position from the retreat limit position, and returns to the normal state in which the game board 1 from the transfer line 2 is transferred in the transfer direction X. This normal state is a mode in which the substrate stopper 6 stops at the retreat limit position and retreats from the transport path of the game substrate 1 in FIG. 5A.

By repeating the steps shown in FIGS. 2 to 6 each time a defect is detected, a predetermined number of game boards 1 are stacked on the lift base 9a, and each time, only the thickness of one game board 1 is added. As shown in FIGS. 7 and 8, the upper transport portion of the roller 9 e in the lowered lift base 9 a reaches a lower limit position that is substantially the same height as the upper transport portion of the drive roller 10 d of the discharge mechanism 10 at the upper limit position. In this case, the operator inserts the transport cart 11 into a space below the tip of the seesaw 10a.

The striker (not shown) is the transport trolley 1
After fixing the position of the roller 9 with respect to the apparatus main body 4, the roller 9
e and the drive roller 10d rotate to convey a block in which a predetermined number of game boards 1 are stacked in the discharge direction Y, and the block is moved from the lift base 9a to the seesaw 10a from the lift base 9a as shown by the solid line to the imaginary line in FIG. Is moved to the lower limit position from the upper limit position to the lower limit position, and the block is transferred from the front end portion of the seesaw 10a to the mounting portion 11a of the carriage 11 during the lowering. In this state, the worker moves the carrier 1
1 is pulled out in front of the seesaw 10a and stored in a predetermined defective material storage.

In short, according to the configuration of this embodiment,
When the game board 1 determined to be defective is transferred from the transfer line 2 to the transfer mechanism 5 and stopped by the substrate stopper 6 in the defective discharge space 3, the receiver 7 b of the transfer mechanism 7 falls under the game board 1. . Then, when the movable plate 5b of the transport mechanism 5 retreats, the game substrate 1 falls from between the front and rear directions of the rollers 5c of the transport mechanism 5 and is received by the receiver 7b. Thereafter, the receiver 7b is retracted and the game board 1 is
When the game board 1 falls from the front-back direction, the abutment rod 7c of the delivery mechanism 7 prevents the game board 1 from falling along with the receiver 7b, and the game board 1 can be dropped horizontally. The falling game board 1 is mounted on the lift base 9a stopped at the receiving position closest to the receiver 7b under the game board 1 and the game board 1
This can eliminate the inconvenience of being hit by a sharp angle when hitting the other portion when it falls and being damaged. In parallel with this mounting, the substrate stopper 6 stops at the retreat limit position, and the movable plate 5b of the transport mechanism 5 returns to the forward limit position,
One operation of discharging one game board 1 determined to be defective from the transfer line 2 for manufacturing a game machine is completed. This discharge operation is repeated each time the game board 1 conveyed on the conveyance line 2 is determined to be defective, so that a predetermined number of the game boards 1 determined to be defective are stacked on the lift base 9a and blocks are formed. When the block is formed, the roller 9e of the lifter 9 and the drive roller 10d of the transfer mechanism 10 are driven to rotate in the same direction at the same speed, and the block can be discharged out of the apparatus. The discharged blocks can be transferred from the transfer mechanism 10 to the transport trolley 11, transported to the defective material storage, and stored.

In the above-described embodiment, the game board 1 on which the design drawing is drawn has been described. However, for example, a game board in which the cell sheet on which the design drawing is drawn is connected to one surface of the game board 1 is a game board. The same applies to the case where 1 is used. In this case, by replacing the gaming board 1 of the embodiment with a gaming board,
It should be clear that this can be done. Note that the design drawing is drawn on the game board means that the design drawing is directly printed on one surface of the game board 1 or the cell sheet on which the design drawing is printed is connected to one surface of the game board 1. included.

The discharge mechanism 8 may be formed as a shooter that slides the game board 1 or the game board dropped from the transport mechanism 5 obliquely downward.

Of course, the present invention can be applied to a structure in which one or both of the delivery mechanism 7 and the substrate stopper 6 are omitted.

In the above-described embodiment, when the game substrate 1 stays in the processing area on the downstream side of the defective discharge space 3, the substrate stopper 6 projects onto the transport path of the game substrate 1 by the rollers 5c of the transport mechanism 5. Then, the normal game board 1 is stopped on the roller 5c, and when the stay of the game board 1 in the processing area on the downstream side is resolved, the board stopper 6 is retracted from the transport path, and the stop is performed. If the substrate stopper 6 is operated in relation to the staying state of the game substrate 1 in the downstream processing region, such as flowing the normal game substrate 1 placed in the downstream processing region, the downstream processing region Work can be made sounder.
