Game consoles such as pachinko machines are no exception, and inspections of nailing conditions or component mounting conditions are performed many times during the manufacturing process. Among them, since many components are attached to the front and back of the board in the final inspection, when moving the conveyor line for inspection, the method of erecting the board and moving it on the conveyor line is used. ing. Although various conveyor lines used for this inspection have been developed, the conveyor 10 shown in FIG.
0 is common. This conveyor 100 is a conveyor 10
There is a rail 101 that goes around the outer circumference of 0, and a large number of pallets 102 are fitted in the rail 101 so as to be movable along the rail 101. This pallet 102
A jig 103 is attached to and is configured to hold a substrate such as a game table as a work upright.
Further, a cable is arranged over the entire length of the rail 101, and this cable is connected to an outlet 104 provided at each station on the rail 101, and a worker connects a power cord extending from the work at the time of inspection to energize the work. It is constructed so that it can be tested.

[0003]

SUMMARY OF THE INVENTION Conveyor 1 having the above structure
In 00, when the work is carried in from one end of the conveyor 100 by the worker, the carried-in work is transferred to the pallet 102.
It is transferred to the upper jig 103 and moves on the rail 101 together with the pallet 102. Then, when the pallet 102 reaches the station where the operator who carries out the inspection stands by,
Stoppers provided on the pallet 102 side and the rail 101 side stop the pallet 102 and the work in front of the operator. When the lever is operated by the operator after the stop, the jig 103 becomes rotatable, and it becomes possible to inspect the front and back of the work thoroughly. After the inspection is completed, the jig 103 is fixed again and the work is moved to the next station. After the completion of all the inspections on the conveyor 100, the work is taken out from the other end of the conveyor 100 and moved to the next process. At this time, the pallet that has been emptied by unloading the work continues to move along the rails and returns to the work loading side. In addition, with respect to the stations on the conveyor that require an energization test, the worker can check the energization state by connecting the work cord to the outlet 104 attached to each station.
However, since the conveyor 100 is configured to support and convey only the lower side of the work, the work is unstablely supported, and sometimes the work is dropped from the jig and the inspection is delayed. Is occurring. Moreover, the jig 10 is used in the inspection at each station position.
Since 3 becomes rotatable, the work becomes more unstable, and at the time of inspection, the worker must support the upper side of the work with one hand and work with the other hand, which makes the inspection extremely difficult. There is a problem. Further, since the outlet 104 for the energization test is arranged for each station, the worker has to insert and remove the power cord of the work for each station, and in the inspection in which the energization test is required many times. In addition to a large work loss, there is a problem in that the pallet 102 moves as it is because the power cord is forgotten and the power cord is broken.

[Operation] At the same time as the work is placed on the roller rail,
The work is supported on the jig on the upper side and on the roller rail on the lower side, and moves on the roller rail while being pressed by the pressing plate of the jig as the pallet device moves.
When the work is taken into the jig, the pressing plate rotates and deviates from the movement path of the work, so that the work can enter below the jig. After that, when the pallet device is stopped by the stopper device, the jig is rotatably switched at its lower portion by the operation of the cylinder provided in the stopper device. On the other hand, since the roller rail below the stopper device mounting position can be swung, the work can be swung by the upper and lower support portions, and the worker can rotate the work and inspect the front and back of the work thoroughly. At such a stopper device mounting position, a power supply test is performed in addition to the component confirmation inspection.Because the power source is attached to the jig, the power cable of the work should be connected at the upstream end of the conveyor frame. If
Electricity is constantly supplied to the work from the power supply rail, and it is possible to obtain a state in which the energization test can be performed at any time. After that, when each inspection is completed and the pallet device is sent to the downstream end of the conveyor frame, the pallet device is taken into the pallet transfer device together with the jig and the work. When the pallet device is taken into the pallet transfer device, the pressing plate of the jig is opened and the work is transferred to the carry-out section and carried out to the next step. Also, the pallet device is transferred to the second conveyor frame by the pallet transfer device and is transported to the upstream portion, and is further transferred to the first conveyor frame by the pallet transfer device in the upstream portion to support and transport the next work. To do. Since a plurality of pallet devices are installed in this upright conveyer, it is possible to convey works one after another.

The reversing device is connected.

Next, the operation of the embodiment will be described. The upright conveyer 1 having the above-mentioned configuration is connected to a production and assembly line such as a game table, and is a device for taking in, transferring and discharging a work which was raised upright in the previous process. When the work is transferred to the upstream side of the upright conveyor 1, the roller 3 in the roller rail 38 at the upstream end of the guide rail portion 3 is transferred.
8c rotates with the drive of the motor 41, the work is taken into the upright conveyor 1, and the lower side of the work is placed on the roller 38c of the roller rail 38. At this time, since the pressing plate 29 of the conveyor unit 2 is rotated to the front side of the conveyor unit 2, the work upper side of the work is fitted into the guide groove 26a of the work guide tool 26 and the work upper side of the work guide groove 26a. The pressing plate 29 is rotated when it is fitted into the inside, and closes the movement path of the work, that is, both ends of the work guide tool 26. When the work power cable is connected to the power supply unit 33 of the jig 24 after the work is taken in, the power supply rail 11 of the pallet transfer frame 8 is always energized, so that the work terminal 3 is energized.
The electric power is always supplied from 2 through the power supply unit 33 during the transportation. After that, when the endless chain 10 in the conveyor unit 2 is driven, a frictional force is generated between the endless chain 10 and the friction plate 23f of the pallet device 23 that comes into contact with the attachment 10a of the endless chain 10, and the pallet device causes the frictional force. As 23 moves, jig 24 also moves. At this time, the workpiece abuts the end surface of the pressing plate 29 of the jig 24 and moves on the roller rail 38 while being pressed by the pressing plate 29. As described above, when the upper side of the work is supported and pressed and conveyed, the work is positioned on the roller rail 38 by its own weight, so that the conveyance device can be simplified and efficient conveyance can be obtained.

When the pallet device 23 arrives at the station position, first, as shown in FIG. 10, the damper 14d of the rear stopper 14 of the stopper device 12 of the stopper installation frame 9 is moved to the rear cam follower 2 of the pallet device 23.
Since it is located on the moving path of 3e, the rear cam follower 23e of the pallet device 23 moving there comes into contact. At the same time, the cylinder 13b of the front stopper 13 is actuated, the stopper block 13c is lowered onto the moving path of the front cam follower 23d of the pallet device 23, and the front cam follower 23d is pressed and fixed. At this time, since the front cam follower 23d is located in front of the front stopper 13, the stopper block 13c is in a state of pressing the front cam follower 23d from the rear. Also, damper 1
4d is a rear cam follower 23 before the pallet device 23 arrives.
Then, the rear cam follower 23e is pressed from the front by descending on the moving path of e. By the action of these two stoppers 13 and 14, the pallet device 23 is restrained from moving forward and backward,
Stop on the spot.

When the pallet device 23 stops at the station, as shown in FIG. 10, the cylinder 15 provided on the stopper table 12a for each station operates to push down the slide shaft 35 of the jig 24. As a result, the right angle link 35a is attached to the base 2 of the jig 24.
The mounting portion of 5 and the connecting portion of the slide shaft 35 are rotated as fulcrums, and the stopper 35b at the tip thereof is operated to be removed from the grooved block 36, while the cylinder 40d of the swivel unit 40 below the roller rail 38 is operated. Cylinder rod is revolving table 40b
Of the through hole 40c. As a result, the work guide tool 26 and the turning table 40b can be turned, and as the slide shaft 35 descends, the bush 34 at the tip of the slide shaft 35 abuts against the upper side of the work and presses the work. The work is not unstable even when it is turned, and the operator can inspect the front and back of the work thoroughly. In addition, since the power cable of the work is connected to the power supply section 33 of the jig 24 at the time of taking in the work, the energization inspection can be easily performed without connecting the power cable to each station. After the inspection of the work is completed, when the lock release switch (not shown) is pressed by the operator, the cylinder 13b of the front stopper 13 is actuated to rotate the topper block 13 to rotate the front cam follower 23d. While opening the movement path,
The cylinder 14e of the rear stopper 14 is activated and the damper 1
4d counters the spring force of the tension spring 14f and pivotally separates from the moving path of the rear cam follower 23e. As a result, the pallet device 23 becomes movable and is moved to the next station by the endless chain 10. When the pallet device 23 is disengaged from the lower surface of the pallet passage sensor 14g, air is discharged from the cylinder 14d of the rear stopper 14, and the damper 14d is again returned to the moving path of the rear cam follower 23e by the spring force of the tension spring 14f.

After that, when the work inspected at each station reaches the downstream end of the conveyor section 2 as the pallet device 23 moves, the friction plate 23 of the pallet device 23 is moved.
f gradually separates from the endless chain 10 and instead contacts the endless belt 22 of the pallet transfer device 16, and as the endless belt 22 is driven by the motor 20, the pallet storage frame of the pallet transfer device 16 is f. It is taken in in 17. After the pallet device 23 is completely stored, the pressing plate 29 is rotated to the front side of the upright conveyor 1.
Immediately after that, the roller 38c of the roller rail 38 self-rotates,
The work is transferred to the unloading section 4 connected to it. At this time, the rollers of the lower rotation unit 4b of the carry-out unit 4 also rotate by themselves,
The transfer of the work to the carry-out section 4 is carried out very smoothly. The workpiece transferred to the carry-out section 4 has its upper side at the upper rotation section 4a.
, And the lower side is supported by the lower rotating portion 4b,
After being rotated in a fixed direction by the reversing unit, the roller of the lower rotation unit 4b is rotated again to be carried out to the next step.

On the other hand, the pallet device 23 after the work is transferred to the carry-out section 4 moves to the end of the second conveyor frame 7 together with the pallet storage frame 17 in accordance with the operation of the rodless cylinder 16c, and also the pallet. The endless belt 22 is driven in the reverse rotation to the time when the pallet device 23 is taken into the storage frame 17, and the pallet device 23 is transferred to the second conveyor frame 7. Then, as with the first conveyor frame 6, the endless belt conveys the pallet transfer device 16 on the upstream side, and the pallet transfer device 16 moves the pallet transfer device 16 to the upstream end face of the first conveyor frame 6, where the next workpiece is transferred. The work is taken in and the above-described operation is repeated to carry the work upright.

In this embodiment, an endless chain is fried as an example of means for conveying the pallet device, but the pallet device is not limited to this, and a belt conveyor or other well-known conveyor device can achieve the same effect.
