Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a conveyance device in which a pusher of a drive chain propels a conveyance moving body along a movement path, and a branch path branching from the movement path via a path switching means is provided. The purpose of the present invention is to provide a conveyance device which is equipped with the above-mentioned methods and can cause a conveyance moving body to branch into a branch route by hand-pushing or the like as necessary.

An embodiment of the present invention will be described below based on illustrative drawings. In FIGS. 1 to 3, reference numeral 1 denotes a transporting moving body, which is provided with an engaged dog 2 that can move up and down on the lower side. A leading truck 3, a second truck 5 with a front load support 4, and a third truck with a rear load support 6.
The truck 7 and the rear truck 9, which is equipped with an operating piece 8 on the lower side for removing the dog 2 of the leading truck 3 of the following conveyance vehicle from the pusher and stopping it, are connected by continuous rods 10, 11, and 12. This is a conventionally known structure in which the wires are connected to each other. 13 is the main movement route, 14
is a branch route, which includes a pair of left and right guide rails 15 that respectively support and guide each truck of the conveyance moving body 1.
, a pair of left and right guide rails 16 for guiding the drive chain arranged below the middle thereof, and a pair of left and right guide rollers 17 that support a pair of left and right guide rollers 17 provided on the load support stands 4 and 6 of the conveyance moving body 1. A guide rail 18 is provided. 19 is each trolley 3, 5,
Horizontal shaft rollers 7 and 9 are provided, and 20 is a vertical shaft roller for steady rest. 21 is the main movement route 13
A main drive chain disposed along the trolley 2 supported and guided by the guide rail 16.
2 and 23 are attached at appropriate intervals, and pushers 2 and 23 are attached to the trolley 22 at an interval that is an appropriate distance longer than the total length of the object 25 supported by the transporting moving body 1.
4 is attached, and this pusher 24 is connected to dog 2.
By engaging with , the transportation moving body 1 is propelled at a constant speed. Reference numeral 26 denotes a route switching means provided at a branch point of the branch route 14, which is conventionally known.

In the conveying device as described above, the main drive chain 21 is detoured from an appropriate position before the branch point of the branch route 14 to an appropriate position beyond the branch point, as shown in FIG. 27, the transport moving body 1 is configured so that the pusher 24 does not propel the transport vehicle 1, and the transport vehicle 1 reaches the entrance of this section 27, that is, the position A where the drive by the pusher 24 is released.
4, the intermediate drive chain 28 is moved to the position B1 shown in FIG. It is arranged along the main movement route 13. This relay drive chain 28 has a drive toothed wheel 31 that engages with the main drive chain 21 at the entrance of the section 27 and is operatively connected to a driven toothed wheel 29 via a chain transmission means 30.
and the take-up gear 32,
It is equipped with an anti-buck pusher 33 that backs up a vertical shaft roller 34 that is pivotally supported on the third truck 7 of the transport vehicle 1, and propels the transport vehicle 1 at approximately twice the speed of the main drive chain 21. It is configured as follows. Incidentally, as shown in FIG. 4, when the route switching means 26 is switched so that the transport moving body 1 enters the branch route 14, it is pushed back by the pusher 33 of the relay drive chain 28. The transportation vehicle 1 includes a leading truck 3 and a second truck 5.
is sent out to position B2 where it enters the branch path 14.

According to the above configuration, as shown in FIG. 33 at approximately twice the speed, and the distance between the front and rear adjacent transport moving bodies 1,
In other words, the distance between the objects 25 to be transported is increased by a maximum of about twice. Therefore, as shown in FIG. 4, when the path switching means 26 is switched to cause the leading end of a specific transportation vehicle 1 to enter the branch path 14 by the pusher action of the pusher 33 of the relay drive chain 28, the position B2 is reached. The transport moving body 1 or the transported object 2 that has reached
Between the rear end of 5 and the front end of the transport moving body 1 or the transported object 25 immediately after, there is a space approximately twice as wide as when moving on the main movement path 13. By using this space, the conveyance moving body 1 at the position B2 can be safely entered into the branch route 14 by manual pushing.

Note that, since the relay drive chain 28 and the main drive chain 21 are interlocked and connected to each other, the pusher of the relay drive chain 28 can be operated almost continuously without making the conveying moving body 1 wait substantially after reaching the position A. 33, and the transport moving body 1 that has reached the position B1 can also be propelled again substantially continuously by the pusher 24 of the main drive chain 28.

As shown in the embodiments above, according to the present invention, the distance between the conveyance movable bodies (or the conveyed objects supported by them) is minimized while moving on the main movement route, While increasing the transport efficiency, the speed of the transport moving body can be increased (not limited to twice) and the interval can be automatically widened only when passing a branch point on the branch route. The front end of the transportation vehicle (or the object supported by it) whose course is curving toward In addition to preventing interference such as the rear ends coming into contact with each other, even when pushing the conveyance moving body that has been backed up until the leading end enters the branch route into the branch route by hand-pushing, the following conveyor Since the space between the movable body and the movable body is widened, the worker can safely and easily carry out rearing work.
