Description

[Detailed description of the invention] Industrial field of application This invention is a system that connects a plurality of carriers traveling on a rail and includes a carrier connection body including a frame for loading transferred objects, which is provided between a drive chain and a removable structure. An engagement hook removal device for driving a carrier of a floor conveyor, which can be pushed by an engagement hook of the floor conveyor, and automatically pull out the engagement hook in the storage section of the transfer path to stop the carrier connected body front and rear in contact with each other. Regarding.

BACKGROUND ART In a conventional floor conveyor having the above-mentioned structure having a carrier linkage, the carrier linkage is stopped by projecting a tripping piece provided in the transfer path into the passage of the engagement hook and engaging the hook. The hook is tripped. Since the carrier coupling body usually coasts forward after the hook is removed, it has conventionally been necessary to provide a stopper separate from the above-mentioned tripping piece. This stopper, for example, engages with a pedestal for loading objects to be transferred, and has a different action area and operating time from the tripping piece, so it is difficult to integrate the two, and therefore, conventional devices have a complicated structure. It also had the disadvantage of being troublesome to control.

Problems to be Solved by the Invention The purpose of the present invention is to simplify the structure and control by integrating the conventional hook tripping piece and the escape prevention stopper.

Means for Solving the Problems This proposal consists of a wide pusher plate provided on the leading carrier of a carrier linkage having a frame for loading transferred objects, and a drive chain that engages with the pusher plate to advance the carrier linkage. A narrow pusher which can be raised and lowered and is biased to the engaging upright position is provided on the rear carrier of the carrier connection body and collides with the pusher of the subsequent carrier connection body, causing the pusher and the pusher plate to engage with each other. a narrow release piece for releasing the pusher; a hook at the tip of the pusher plate that is supported outside the movement path of the pusher and the release piece so as to be able to move in and out of the movement path of the pusher plate, and that locks the pusher plate within the movement path; A carrier drive engagement hook tripping device has a stopper for preventing the carrier from running away, and a stop member integrally formed with a cam portion at the rear end that comes into contact with a wing projecting outwardly to release the engagement. This is the summary.

Operation When the stop member is entering the passage of the pusher plate, when the pusher being pushed by the carrier coupling body arrives, the wing is pushed down by the cam part of the stop member and the pusher is pulled out from the pusher plate. Then, the carrier coupling body loses its driving force, and after some coasting, the wide pusher plate is stopped by the end hook of the stop member.
The pusher of the succeeding carrier assembly collides with the release piece of the stopped preceding carrier assembly, is pulled off from the pusher plate, and is stopped substantially in contact with the preceding carrier assembly, and is stored.

Next, when the stop member is moved out of the path of the pusher plate, the carrier coupling body, which has been locked to the end hook of the stop member, engages the incoming pusher with the pusher plate and starts moving. Immediately after the start, the stop member is moved into the passage of the pusher plate again, and the subsequent carrier connection is stopped in the same manner as described above. Therefore, even if the carrier linkage is stopped in a storage section with a downward slope and the following carrier linkage starts at the same time as the leading carrier linkage starts, the subsequent carrier linkage can be reliably moved by operating the stop member. It can be stopped.

Embodiment In FIG. 1, a carrier coupling body 1 connects carriers 4a, 4b, 4c, and 4d running on a carrier rail 3 with a running roller 2 to a coupling rod 5 and a conveyed object M.
A drive chain 9 is coupled to and suspended from a trolley 8 which runs on a trolley rail 7 provided directly below the rail 3, and the trolley 8 and the leading carrier 4a An engaging device 10 is provided between them, and the drive chain 9 pushes the carrier link 1 in the direction of the arrow.

The engagement device 10 includes a pusher plate 1 having a width close to the full width of the carrier, which is protruded from the lower part of the carrier 4a.
1, and a pusher 13 pivotally supported by a pin 12 at the center of the front part of the trolley 8.The pusher 13 is biased by a weight part 14 protruding forward of the trolley 8, and a narrow hook 15 at the rear part is pushed. It engages approximately in the center of the rear inclined surface 11a of the pusher plate 11.
A wing 16 is fixed to the pusher 13 above the pin 12 and projecting to one or both sides.
The wing 16 consists of a plate-shaped body whose front part is tilted downward.
Although the front surface is flush with the front slope 17 of the pusher 13, it may be formed by penetrating and fixing a round bar to the pusher 13.

The rear carrier 4d is provided with a release piece 18 that engages with the front slope 17 of the pusher 13 in order to release the engagement between the trailing carrier connector and the drive chain when the carrier connector 1 approaches forward and backward.

In FIGS. 2 to 4, the carrier 4a has a vertical shaft guide roller 19 fixed to a guide plate 20 fixed to the rail 3.
Run guided by. A pusher plate 11 is attached to one side of the front end of the storage section of the carrier coupling body 1.
A stop member 21 is provided for disengaging the hook 15 from the hook 15. The stop member 21 is made of a strip-like body elongated in the transport direction, and the lower ends of columns 22 and 23 fixed to the front and rear are pivotally supported on the floor by hinges 24 so as to be tiltable laterally, and the air cylinder 2 acts on the intermediate fixing member 25.
6 to push the stop member 21 to the pusher plate 11.
entrance and exit from the passageway. The stop member 21 has a carrier escape prevention hook 27 formed at the front end and a cam portion 28 inclined slightly upward at the rear end. When the stop member 21 is in the passage of the pusher plate 11, the hook 27 is The cam portion 28 can engage with the front inclined surface 11b of the pusher plate 11 to stop the carrier coupling body 1, and the cam portion 28 presses down the wing 16 to remove the hook 15 from the pusher plate 11. The pulled pusher 13 is stopped by the stop member 2
Pass through the inside of the carrier connector 1 in a lying down position.
After coasting a little, the pusher plate 11 is stopped by the hook 27.

In the above embodiment, the width of the pusher plate 11 is set to be equal to or less than the interval between the rails 3, but the pusher plate 1
1 below the rail 3, the width can be made wider than the rail spacing.

Effects of the invention In the present invention, the cam portion that pulls out the pusher for pushing the carrier coupling body from engagement with the pusher plate and the hook that stops the carrier coupling body coasting after the removal are formed on the same stopping member. Moreover, since the stop member does not enter or leave one side of the pusher plate and obstruct the passage of the pusher, the stop member, its support, and operation structure are simple and reliable, and it is easy to remove the pusher and connect the carrier connection body. Since the stop and stop operations are performed simultaneously, there are advantages such as simple stop control.
