Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a line connecting device for connecting liner type assembly machines, each having an inlet and an outlet for feeding and discharging objects including good and defective products. Conventionally, when lines are connected between linear assembly machines, defective products are rejected in a direction perpendicular to the conveyance line, only good products are sent onto the conveyance line, and defective products are rejoined to the good product conveyance line after being reworked. A so-called bypass method was used. However, the conventional line connection method has the disadvantage that it takes up a large amount of space when the stock is large, and unless the stock is large, the operating rate of the machine decreases when the lines are connected in high-speed assembly machines. was.

Next, the operation will be specifically explained.

Receive information on whether assembly defects are mixed in the short substrates 1 fed from a pre-connection machine (not shown), whether they are good or defective, and receive information on operation and stoppage of the machines before and after the connection device. transport and storage of the short base material 1 that is fed into the line connection device;
It instructs the feeding and feeding of the stored short substrate 1, etc. When the connecting device is fed by a transport member of the machine before the connection (not shown), the feeding detection sensor 2 turns ON and detects that the short substrate 1 has been fed into the connecting device. . According to the information on the good and defective products of the machine before connection, when a short base material containing defects, that is, a defective product is fed, the defective product stopping stopper 4 stops the conveyance from the lower part of the first conveyor belt 3. It rises to the upper surface of the belt 3, and then the first
The conveyor belt 3 rotates, and the short substrate 1 on the first conveyor belt 3 hits the defective product stopper 4 and stops, and is conveyed from the entrance to just below the defective product stocker and stopped. Defective product stop detection sensor 5
When the power is turned ON, the push-up plate 6 rises, and the defective short base material 1 is lifted directly above the first conveyor belt 3, and the short base materials that have already been stacked are also lifted to a position. After the defective product support shutter 7 opens and further rises, and the defective short substrate 1 rises to the upper surface of the defective product support shutter 7, the defective product support shutter 7 closes and the push-up plate 6 descends, and the first conveyance begins. By descending below the belt 3 and stopping, the defective short substrates 1 are stacked and stored in the defective product stocker 8. Defective product stocker 8
The defective short substrates 1 piled up in the stack are manually taken out from the top of the defective product stocker 8, corrected for assembly defects, and recycled into non-defective products.
It is inserted from the top of the non-defective stocker 15 and is considered to be a non-defective stock. In addition, the defective product stocker upper limit detection sensor 9 installed on the top of the defective product stocker 8 is turned ON.
However, when it is detected that the stock of defective products is full, the machine (not shown) before connection is stopped. When a good short substrate 1 with no assembly defects is fed into the coupling device, the good product stopping stopper 11 rises from the lower part of the second conveyor belt 10 to the upper surface and connects the first conveyor belt 3 and the second conveyor belt 10. The conveyor belt 10 of No. 2 is rotated and the non-defective short substrate 1 on the belt is stopped by the non-defective stopper 1.

is turned on, the first conveyor belt 3 and the second
The rotation of the conveyor belt 10 is stopped. At this time,
When the exit stop detection sensor 19 turns OFF and detects that there is no short substrate 1 on the third conveyor belt 17, the exit stop stopper 18 moves from the bottom of the third conveyor belt 17 to the upper surface. The second conveyor belt 10 and the third conveyor belt 17 rotate, and the short substrate 1 collides with the exit stopper 18 and stops, and the exit stop detection sensor 19 is activated. By turning on, the second conveyor belt 10 and the third conveyor belt 1
7 is stopped, the exit stopper 18 is lowered, and the non-defective short substrate 1 is conveyed from directly below the non-defective stocker 15 to the exit stopper 18. Thereafter, it is fed from the coupling device to the coupled machine by a transport member (not shown) of the coupled machine. When the non-defective short substrate 1 fed into the above-mentioned coupling device has been conveyed to just below the non-defective stocker 15, the exit stop detection sensor 19 is turned on and the non-defective short substrate 1 is placed on the third conveyor belt 17. If it is detected that there is a
In other words, the non-defective product stopping stopper 11 is stopped until the short substrate 1 on the third conveyor belt 17 is fed to the connected machine by the conveying member (not shown) of the connected machine. After the exit stop detection sensor 19 is turned OFF, the product is transported from directly below the good product stocker 15 to the exit stop stopper 18 as described above. When there is a non-defective short substrate 1 waiting directly below the non-defective stocker 15, if another non-defective short substrate 1 is fed into the inlet of the coupling device, the defective product stopper 4 is raised and the first The conveyor belt 3 of No. 1 is rotated to convey the supplied non-defective short substrate 1 until it hits the conveyance stopper 4, that is, right below the defective article stocker 8. At the same time, another non-defective short substrate 1 that was waiting directly below the non-defective stopper 15 raises the second push-up plate and moves the second conveyor belt 10 up.
The good product support shutter 14 is opened at a position where it hits the good short substrate that has already been picked up by the good product stocker 15, and the push-up plate 13 is further raised to lift the short substrate 1 from the upper surface of the good product support shutter 14. Later good quality shutter 14
is closed, the second push-up plate is lowered, and the non-defective short substrates 1 that have been waiting on the second conveyor belt 10 are stacked on the non-defective stocker 15. After that, the defective product stopping shutter 4 is lowered, the first conveyor belt 3 and the second conveyor belt 10 are rotated,
After conveying the non-defective short substrate 1 temporarily stopped directly below the defective stocker 8 until it hits the non-defective stopper 11, that is, directly below the non-defective stocker 15,
The first conveyor belt 3 and the second conveyor belt 10 are stopped. When the non-defective short substrate 1 is transported from directly below the non-defective stocker 15 to the exit stopper 18 and the non-defective short substrate 1 is not fed into the inlet of the coupling device, the non-defective products stacked on the non-defective stocker 15 In order to unload the short substrate 1 onto the second conveyor belt 10 directly below the non-defective stocker 15,
After raising the second push-up plate 13 to the upper surface of the non-defective product support shutter 14 and place the non-defective short substrate 1 on the second push-up plate 13, the non-defective product support shutter 14 is opened and the second push-up plate is lowered. At the position where the non-defective short substrate 1 has been lowered, the non-defective support shutter 14 is closed, and the second push-up plate is lowered to below the second conveyor belt 10, and the non-defective short substrate 1 is Grate just one piece. Also, a sensor 16 for detecting the upper limit of stacking of non-defective products installed directly above the non-defective stocker 15
is for detecting the fullness of the good stock 15, and the good stock stock pick-up upper limit detection sensor 16 is
Turns ON and stops the machine before connection when full is detected. Furthermore, if the machine after connection is stopped and the machine before connection is operating, the exit stop detection sensor 19
is ON, the short substrate 1 is placed on the third conveyor belt 17.
If so, both good and defective products are fed into the coupling device without stopping the machines before connection, and stacked in the defective product stocker 8 and non-defective product stocker 15, respectively, until the defective product stocker upper limit detection sensor 9 is activated.
ON, good product stocker upper limit detection sensor 16 is ON.
You can stack up until it becomes . In addition, if the cycle time of the machine before connection is faster due to a slight difference in the cycle time between the machine before connection and the machine after connection, the cycle time of the machine before connection is faster, it will be increased in the same way. Conversely, if the machine before connection is stopped and the machine after connection is operating, or if the cycle time of the machine after connection is faster due to a slight difference in cycle time, the stock of non-defective products is 15. The second conveyor belt 1
The good short substrates 1 that have been picked up to zero are unloaded one by one and fed into the connected machine as described above.

As described above, the present invention has a defective product stocker on the conveyance line to stack defective products, and a non-defective product stocker to stack, unload, transport, and connect non-defective products. (1) Both non-defective products and defective products can be stocked. (2) Space can be significantly reduced (3) High-speed linear assembly machine allows lines to be connected without reducing operating efficiency due to large stock capacity. It is more effective in interlinking.

(4) Even if either of the machines before or after the connection is stopped, the machine in operation can be operated until the stock amount is stacked or unloaded without stopping the machine, and the present invention further provides the above-mentioned The present invention can be applied not only to a line connecting device for conveying short substrates, but also to a line connecting device for conveying assembled base carriers such as pallets.
