Further, as shown in FIG. 5, in the towing conveyance line 2, the hook 40 of the self-propelled towing trolley 6 is engaged with the towed engagement piece 17 of the front trolley 9 of the conveyance moving body 4. In this state, the self-propelled cart 6 is moved forward by the rotation of the drive wheels 65, and the transportation vehicle 4 is towed and moved by the self-propelled cart 6, and the object supported on the hanger 11 is
The general goods 45 can be conveyed once along the traction conveyance line 2. The action of pulling the general transportation vehicle 4 by the self-propelled towing truck 6 can be canceled by moving the hook 40 upwardly by the solenoid 42 and disengaging it from the towed engagement piece 17.

When the transport moving body 4 is to enter the storage line 6 from the boosting transport line 1, the route switching means 7 is switched as shown in FIG. The transfer body 4 is entered into the target storage line 6. At this time, before the boosting self-propelled trolley 5 is transferred onto the route switching means 7, the front trolley 9 in the conveyance moving body 4 is transferred onto the guide rail 12 of the storage line 6, and the driven roller 20 is transferred to the third As shown in the figure, it begins to come into pressure contact with the drive shaft 26 which rotates and moves from the lateral side. Due to the pressure contact between the driven roller 20 and the drive shaft 26, a thrust is applied to the transport moving body 4, and this thrust causes the till transport moving body 4 that has entered the storage line 6 to guide the storage line 6. It will move forward on the rail 12. On the other hand, the self-propelled boosting trolley 5 that has pushed the conveying moving body 4 into the rear end of the storage line 6 moves straight on the boosting conveyance line 1 without entering the storage line 6 by switching the route switching means 7. This can be used to boost another conveyance moving body 4.

Enter storage line 6 as described above and receive! 9
The transportation moving body 4 moves forward on the storage line O by the thrust applied by the IlO roller 20 and the drive shaft 26, and the lever 21 is pushed up by the stopper 45 provided at the end, and the bracket 19 is pushed up. The driven roller 2o is rotated backward against the puller 2i5, and the driven roller 2o is switched to an idle rotation position parallel to the drive shaft 26, thereby automatically stopping. The conveyance movable body 4 that approaches the rear of the conveyance movable body 4 that has stopped in this way is
As shown by the imaginary line in the figure, the transportation moving body 4 has stopped first.
The driven roller 20 is switched to the idle rotation position by the cam 25 in the same way as the stopper 43 described above, so that the driven roller 20 is automatically stopped in a state connected to the conveying moving body 4 that has stopped previously. In this way, one transporting moving object 4 that enters each storage line 6 is automatically stored sequentially from the head position of the line.

When transporting the transport vehicle 4 in the storage line 6 to the traction transport line 2, as shown in FIG. A self-propelled towing trolley 6 is kept on standby on the lower side. On the other hand, in the storage line 6, the stopper 45 is released, and the driven roller 20 of the leading transport moving body 4 is moved by the spring 2? ) by returning it to the driven position with the urging force of ), a thrust force is again applied to the conveyance moving body 4, and it is propelled toward the route switching means 8. The driven roller 20 of the transport moving body 4 started in this way is moved to the drive shaft 2.
6, the feeder 44 is driven, and the conveyance moving body 4 is driven by the feeder 44, and its front trolley 9 passes through the path cutting means 8 to the towing conveyance line 2.
60 self-propelled carts for towing and 40 hooks have entered the area and are waiting.
is pushed back to the position where the towed engagement piece 17 engages. After this, the self-propelled towing vehicle 6 pulls the transportation vehicle 4 onto the towing conveyance line 2, and the self-propelled vehicle 6 tows and moves the single transportation vehicle 4 along the towing conveyance line 2 as described above. Good.

In the storage line 6, the conveyance movable body 4 that follows the started conveyance movable body 4 is moved when the cam 25 is separated from the cam driven roller 22 (the driven roller 20 is automatically moved by the biasing force of the spring 26). Since it is automatically returned to the driven position and starts automatically following the started transport moving body 4, it is only necessary to automatically stop this 112 transport moving body 4 with the stopper 43 U'.

In addition, without using the feeder 44, the self-propelled towing trolley 6
It is also possible to use the self-propelled traction trolley 6 to move the transport vehicle 4 backwards into the storage line 6 without pulling it out from the storage line 3 to the traction line 2. Alternatively, the feeder 44 may be configured to feed the conveyance moving body 4 to a position where the entire conveyance body 4 exits into the traction conveyance line 2 . Furthermore, in this case, the transporting mobile body 4 can be propelled along the transport line 2 by using the self-propelled rearing trolley 5 instead of the self-propelled towing trolley 6. Of course, on the contrary, a feeder that pulls the conveyance movable body 4 from the boost conveyance line 1 into the slage line 6 may also be used, and when such a feeder is used together, the conveyor line 1 may be It is also possible to propel the conveyance moving body 4 with the drag 11 self-propelled cart 6.

In addition, in the embodiment, a self-propelled trolley 5 exclusively used for boosting and a self-propelled trolley 6 exclusively used for towing are used, but it can be used for both boosting and towing, as it is equipped with a pusher medium 64 for boosting and a hook 40 for towing. It is also possible to use a self-propelled trolley. In this case, if a combination of the pusher 64 for boosting and the hook 40 for towing is provided on each of the front and rear sides of the self-propelled cart, the self-propelled cart can also be used in the backward direction. Of course, even in the self-propelled trolley 5 dedicated to boosting and the self-propelled trolley 6 dedicated to traction as in the above-described embodiment, the pusher i for boosting is used as described above.
54 and towing hooks 40 can be provided on both the front and rear sides so that these self-propelled carts can be used in either direction.

As in the above embodiment, the conveyance equipment of the present invention includes a conveyance moving body movable along a guide rail, and a detachable self-propelled trolley (in the embodiment The self-propelled vehicle for boosting 5) and the self-propelled vehicle for towing 6) and the transportation vehicle that has been separated from the self-propelled vehicle described in 6:1 and entered the storage line are propelled on the storage line and automatically stored. and a drive shaft rotatably supported along the storage line, and the feeding device is provided on each of the conveying moving bodies and is in pressure contact with the drive shaft in an oblique driven position. A driven roller that can be switched to a state in which no force is applied, and a driven roller that is provided on each conveying moving body to propel the driven roller of the subsequent conveying moving body from the driven state when the following conveying moving body approaches. It has a means (a cam 25 in the embodiment) for switching to a state where it does not receive force and automatically stopping the following +a<transfer moving body (cam 25 in the embodiment). (Although it can be reliably propelled with the necessary thrust and speed, in the storage line, the conveyance moving body is moved by a simple feeding device that uses a drive shaft and a driven roller as described in Ail. Since it can be loaded and automatically stored, it is possible to use a self-propelled cart as a propulsion means for carving into a plurality of movable bodies for narrowing down, and it is possible to use a self-propelled trolley as a propulsion means to carve into a plurality of movable bodies for transportation, which is expensive compared to the number of movable bodies for transportation. By reducing the number of trolleys, it can be expected to reduce the cost of the entire facility.
