Description

[Detailed Description of the Invention] The present invention provides a means for supporting an object to be transported via a support on the transport vehicle, and a movement path of a drive chain equipped with a pusher for propelling the transport vehicle below the movement path of the transport vehicle. The object of the present invention is to provide a conveyance device equipped with the above-mentioned conveyance cart and drive chain, in which the conveyance cart and drive chain are moved below the floor surface, and only the conveyed object supporting means is moved above the floor surface.

Hereinafter, one embodiment of the present invention will be explained based on the attached illustrative drawings. In FIG.
3 is the object to be transported, and 3 is a drying oven. Figures 2 and 3
In the figure, 4 is the front truck, 5 is the rear truck,
Bearing members 10 and 11 are pivotally attached to the upper ends of columns 6 and 7 erected from both carts 4 and 5 by horizontal horizontal shafts 8 and 9, and support means 13 for supporting an object to be transported (such as an automobile body) 2. The front and rear ends of the bearing member 10,
11 with vertical shafts 14 and 15. 1
Reference numeral 6 denotes a pair of left and right guide rails that support both the front and rear bogies 4 and 5 via wheels 17 and 18. 19,
Reference numeral 20 denotes a steady rest roller pivotally supported by both the front and rear carts 4 and 5.

Reference numeral 21 denotes a cylindrical drive chain guide rail temporarily installed below the center of the movement path of both the front and rear carts 4, 5, and has a pusher movement slit 22 on the upper side. Pushers 23 are provided upwardly projecting from the drive chain 24 moving within the guide rail 21 at appropriate intervals, and project upwardly from the slit 22. Reference numeral 25 denotes a driven dog which is pivoted to the lower front end of the front truck 4 about a horizontal horizontal shaft 26 so as to be able to swing up and down within a certain range, and has a hook portion 27 at the front end that engages with the pusher 23. Reference numeral 28 denotes an operation piece for stopping the following truck which projects rearward from the lower part of the rear end of the rear truck 5, and pushes up the driven dog 25 of the following truck when approaching the vehicle to separate it from the pusher 23.

29 is a groove formed under the floor surface of the drying oven 3, and as shown in FIG. It is constructed within the groove 29.
A drying hearth 31 covers the groove 29 and is provided with a heat insulating layer like the side walls and ceiling. This drying hearth 31 is formed with a slit 32 through which the supports 6 and 7 move. 33 is a drying hot air discharge means.

Both the front and rear carts 4 and 5 that support the conveyed object 2 by the support means 13 have a driven dog 25 that supports the pusher 2.
3, it is moved in the direction of arrow 34, but before entering the drying oven 3, it enters the groove 29 through a downward slope and moves under the drying hearth 31. In this drying oven section, the supports 6 and 7 move vertically through the slit 32, and move the support means 13 for supporting the object 2 into the drying oven 3 at a low position near the drying hearth 31. The conveyed object 2 on the supporting means 13 is dried in the drying oven 3.

In the above embodiment, the conveying device of the present invention is used as a conveying means in the drying oven section, but the conveying device of the present invention can also be used as a conveying means in other conveyance routes. For example, it can be used as a transport means in a work line where various operations are performed on objects to be transported, or simply as a transport means to transport objects from one place to another. Further, the conveyance device of the present invention can be used over the entire length of the conveyance route, or it is also possible to use the conveyance device of the present invention only in a specific section of the conveyance route as shown in the embodiment.

A feature of the conveyance device of the present invention that can be implemented as described above is that a pair of front and rear conveyor carts that move under the floor are provided with supporting columns that loosely fit into slits provided in the floor surface, and that the upper ends of both of these supports are protruded from each other. Further, the front and rear ends of the conveyed object support means on the floor are connected by a flexible connection structure, and a movement path of a drive chain with a pusher for propelling the pair of front and rear conveyance carts is provided under the floor. .

According to the conveyance device of the present invention, only the object to be conveyed and the support means for supporting it move on the floor, and the entire conveyance device including the conveyance cart and drive chain moves on the floor. Compared to a moving conveyance device, the height of the conveyed object above the floor surface can be significantly lowered, which is convenient when performing various operations on the conveyed object. In addition, since the floor surface is provided with only slits through which the pillars supporting the support means move, it is easy for people, work carts, etc. to cross the conveyance route on this floor surface, and the floor surface can be effectively used. It can be used.

Furthermore, as described above, columns are provided that protrude from the pair of front and rear transport vehicles to loosely fit into the slits in the floor surface, and both front and rear ends of the means for supporting the transported object on the floor surface are freely attached to the upper ends of these two columns. Because they are connected by a connecting structure, they can be used not only in horizontal curved route sections, but also in downhill sections where the traveling routes of the front and rear transport vehicles move from above the floor to below the floor, or vice versa. The transport vehicle can be made to run smoothly. Moreover, since the flexible connecting structure portion is always exposed above the floor surface, it is not only convenient for maintenance and inspection, but also the portion that passes through the slit on the floor surface can be made thinner to make the width of the slit narrower. However, the supporting strength of the conveyed object supporting means can be sufficiently increased by providing necessary reinforcement under the floor surface to the pillars protruding from the conveying carriage.
