At the same time, the lock lever 9 moves the engaging pins 4 and 5 at the lower limit position and the upper limit position.
This is an engagement pin switching means designed to lock 5. Reference numeral 10 denotes an auxiliary wheel, which is supported by fixed horizontal horizontal shafts facing in two places, front and rear, at positions closer to the left and right sides, and its ground contact level is slightly higher than the ground contact level of each of the swivel wheels 3. It is configured as follows. Reference numeral 11 denotes an attachment for supporting a transported object attached to the transport vehicle 1.

As shown in FIGS. 1 to 5, the trolley conveyor 2 is disposed on the floor side of the transport vehicle 1, is movably supported by a guide rail 12, and is connected to a drive chain 13. It is composed of a driving trolley 14 and a trolley connection body 16 for driving a bogie that is movably supported by a guide rail 15 disposed above the guide rail 12. The trolley connection body 16 for propulsion of the bogie
comprises a first trolley 20 to a fourth trolley 23 which are connected to each other by connecting rods 17 to 19 so as to be relatively movable vertically and horizontally. and a pusher claw 25 that engages with the pusher 24 held at the upper limit position by a spring,
The second trolley 21 to the fourth trolley 23 have drive release tools 26 to 2 that push down the pusher 24.
8 is provided protrudingly. Further, the second trolley 21 and the third trolley 22 have engagement plates 29 and 30 provided with engagement holes into which the pair of front and rear engagement pins 4 and 5 of the transport vehicle 1 are fitted at the lower limit position. It is provided. In particular, the engagement hole 30a provided in the engagement plate 30 of the third trolley 22 is formed long in the front-rear direction. The engaging plates 29, 30 and the connecting rods 17 to 19 protrude upwardly from the plate surface 31 that supports the flexible wheels 3 of the transport vehicle 1, and the guide rails 12, 15 protrude downwardly from the plate surface 31. It is arranged.

In FIGS. 2 and 4, reference numeral 32 denotes a guide rail for auxiliary wheels installed in a specific section of the movement route of the transport vehicle 1, such as a storage line. Auxiliary wheel 1
This is a guide rail with a triangular cross section that fits into the circumferential groove of 0. When the pair of front and rear auxiliary wheels 10 rides on this guide rail 32, the transport vehicle 1 is supported in a slightly inclined state in the left and right direction. A pair of front and rear swivel wheels 3 on the upper side of the incline are on the plate surface 31

In FIGS. 7 to 9, reference numeral 33 indicates a first drive release tool 28 protruding from the fourth trolley 23.
The second drive release tool has a longer rearward protrusion than the first drive release tool 28, and is detachably attached to the side surface of the first drive release tool 28 with a bolt nut 34. This second drive release tool 33 is a pusher 2
It acts on an overhanging portion 35a of an inclined cam surface 35 formed on the front end side of the push rod 4, and is positioned laterally away from the movement path of the pusher claw 25. Therefore, as shown in FIG. 9, even when the second drive release tool 33 is attached, the front and rear trolley coupling bodies 16 are connected to the fourth trolley 23 regardless of the second drive release tool 33. Contact portions 23a and 2 provided on one trolley 20
They can abut each other at 0a.

To explain how to use the conveyance device configured as described above, the pair of front and rear engagement pins 4 and 5 of the conveyance cart 1 are lowered, and the engagement plate of the second trolley 21 of the trolley coupling body 16 is By engaging the engagement plates 30 of the 29 and third trolleys 22 through their respective engagement holes, and coupling the transport vehicle 1 and the trolley coupling body 16, the drive trolley 14
As the pusher 24 engages with the dog 25 of the first trolley 20 in the trolley coupling body 16 and pulls the trolley coupling body 16, the transport vehicle 1 is pulled together with the trolley coupling body 16. , move along a fixed route. When the moving carrier 1 approaches the stopped preceding carrier as shown in FIG. 6, the drive trolley 14
The fourth trolley 2 in the trolley connection body 16 in which the pusher 24 is integrated with the preceding stop conveyance truck
The trolley is pushed down by the first drive release tool 28 of No. 3, and is separated from the dog 25 of the trolley connection body 16. Therefore, the transport vehicle 1, together with the integrated trolley connection body 16, is automatically stopped and stored in a line with the preceding stopped transport vehicle.

As shown in FIGS. 8 and 9, when the second drive release tool 33 is attached to the first drive release tool 28, the second drive release tool 33 pushes down the pusher 24. Therefore, Figures 6 and 7
As is clear from the comparison of the figures, the pusher 2
4 is pushed down earlier, and the first trolley 2 in the subsequent trolley connection body 16 is released from driving.
The coasting distance of the stopped trolley connection body 16 until it collides with the fourth trolley 23 becomes longer.

In order to automatically stop the transport vehicle 1 at the head of the storage line, as shown in FIG. A stopper 36 is used. Therefore, a second drive release tool 37, which operates in the same manner as the second drive release tool 33, can be removably attached to this stopper 36 with a bolt nut 38.

The pusher 24 removed from the dog 25 releases each drive release tool 26 to 2 in the trolley connection body 16.
8, and also for the dog 25, as shown in FIG. (Second drive release tool 33
(including this second drive release tool 33), if the dog 25 is continuous with the dog 25, it is possible to pass under it in the same way.

The drive release tools 26 and 27 provided on the second trolley 21 and the third trolley 22 are used when the transport vehicle 1 is stored diagonally. The tools 26 and 27 can be omitted. Further, when these drive release tools 26 and 27 are used, the second drive release tool 33 can be detachably attached to these drive release tools 26 and 27 as well.

The transport vehicle 1 that is propelled as described above is
When entering the section where the auxiliary wheel guide rail 32 is laid, the auxiliary wheels 10 of the transport vehicle 1 ride on the guide rail 32, engage with this guide rail 32, and roll. As a result, the transport vehicle 1 is tilted so that the side where the auxiliary wheels 10 are located is slightly higher, and moves with the free wheels 3 on the same side floating above the plate surface 31. In this state, the transport vehicle 1 has a pair of front and rear auxiliary wheels 10.
The engagement between the guide rail 32 and the guide rail 32 completely suppresses the vibration in the left and right lateral directions, and the guide rail 32
Go straight along.

The transport vehicle 1 raises the pair of front and rear engagement pins 4 and 5 to connect the engagement plate 2 of the trolley connection body 16.
By detaching it from the trolleys 9 and 30, it can be separated from the trolley connection body 16 and removed from the fixed conveyance path.

The conveying device of the present invention can be implemented and used as described above, and includes a drive provided on the rear end side of the conveying moving body (a combination of the trolley connection body 16 and the conveying cart 1 of the embodiment). As a release tool, a first drive release tool with a short amount of rearward protrusion from the conveyance moving body and a second drive release tool with a long amount of rearward protrusion and which can be attached and detached are provided. The drive release tool is configured so that it does not come into direct contact with the conveying moving body that follows the drive being released, so it can be When the object to be conveyed by the conveying moving body is a heavy object, the engagement between the pusher and the pusher of the succeeding conveying moving body is released by attaching the second drive release tool. The distance between the following conveyance moving body and the stopped conveyance moving body is increased, and the deactivated subsequent conveyance moving body collides with the stopped conveyance moving body and stops. Since the coasting distance can be increased, the shock at the time of a collision stop can be reduced, and the occurrence of cargo collapse etc. can be eliminated. Of course, if the pusher movement speed is not particularly fast,
When the object to be transported is a lightweight object, the second drive release tool is removed, and the subsequent transport moving body is automatically stopped by the first drive release tool with a short rearward protrusion, It is possible to minimize wasted time when automatically stopping the following conveyance moving body and improve efficiency even a little.

In particular, as shown in the embodiment, in the storage line, means (auxiliary wheels 10 and guide rails 32) for preventing the transport moving body from swinging in the left and right lateral directions.
When used in combination, the conveyance moving body can be stopped even more safely.

In the embodiment, a conveyance device in which the pusher is movable in detachment is shown, but the present invention can also be implemented in a conveyance device in which the pusher is movable in detachment. Furthermore, although a trolley-type vehicle is shown as the conveyance moving body, it may also be of a type in which the object to be conveyed is suspended and conveyed.
