Description

[Detailed description of the invention] The present invention is a transport device using a trolley, which is constructed by providing a driven pin on a trolley that can travel along a fixed route, and disposing a drive device that can engage with the driven pin along the fixed route. It is related to.

Conventionally, in this type of conveying device, there would be no problem if the fixed path always consisted of only horizontal sections, but if the fixed path included an ascending section or a descending section, these sections Care must be taken to ensure that the carrier's object support platform is in a horizontal position.

The object of the present invention is to provide a conveyance device using a trolley that can run the trolley with the object support stand always in a horizontal position in a fixed path including all of the horizontal section, the ascending path section, and the descending path section. At the point.

In order to achieve the above object, the conveyance device using a trolley according to the present invention is provided with a driven pin provided on a trolley capable of traveling along a fixed route, and a drive device having a drive protrusion that can be engaged with the driven pin along the fixed route. The truck is arranged as follows: a truck body; a rocking table capable of vertically swinging, the rear end of which is attached to the truck body via a first left-right axis; and a front end of the truck; a vertically swingable conveyed object support stand attached via a second left-right axis; a first roller attached to the side of the rocking stand; and a first roller attached to the side of the conveyed object support stand. A first cam rail that acts on the first roller is disposed in a descending path portion of the constant path, and a second cam rail that acts on the second roller is disposed in a rising path portion. It is set up and configured.

According to this configuration, in the horizontal part, since the rocking table and the object support stand are stacked on top of the cart main body in a horizontal position, the horizontality of the object support stand can be maintained. In,
The second cam rail acts on the second roller to move the object support base upward around the second left-right axis. In addition, in the descending path section, the first cam rail acts on the first roller to move the rocking table upward around the first left-right axis, thereby tilting the main body of the cart. However, it is possible to maintain the horizontal level of the conveyed object support table together with the swing table. In this way, the cart can be run with the object support stand always in a horizontal position on a fixed path including all of the horizontal portion, the ascending path portion, and the descending path portion.

An embodiment of the present invention will be described below based on the drawings. In FIGS. 1 and 2, 1 is a truck, and a truck main body 3 has a pair of left and right wheels 2 at the front and rear, respectively.
and a rocking table 5 whose rear end is attached to the truck body 3 via the first left-right shaft 4 and which can swing up and down.
and a vertically swingable conveyed object support stand 7 whose front end is attached to the front end of this rocking table 5 via a second left-right axis 6; a conveyed object support section 8; a first roller 9 attached to both sides (or one side) of the rocking table 5;
A second roller 10 attached to both sides (or one side) of the conveyed object support table 7, a driven pin 12 with a guide roller 11 hanging from the front part of the truck body 3, and a second roller 12 attached to the front side of the truck body 3 In the horizontal part, the swing table 5 and the conveyed object support stand 7 are stacked on top of each other with respect to the cart main body 3, so that the conveyed object support stand 7 is It is designed to remain horizontal. 14 indicates an object to be transported. The truck 1 has wheels 2 on a floor plate 15.
By positioning both guide rollers 11 and 13 within the groove 16 formed in the floor plate 15, it is possible to run on a fixed path. floorboard 15
A guide rail 18 for guiding a roller chain type drive device 17 is disposed below, and the drive device 1
A driving protrusion 19 that can be engaged with the lower end of the driven pin 12 is provided on the 7 side. A first cam rail 20 that acts on the first roller 9 from below is disposed in the descending path portion of the constant path, and a first cam rail 20 that acts on the second roller 10 from below is provided in the ascending path portion. A second cam rail 21 is provided.

In a fixed path, the driving force of the drive device 17 is transmitted to the truck 1 via the drive protrusion 19 and the driven pin 12, causing the truck 1 to travel. And Figures 1 and 2
As shown in the figure, since the cam rail does not act on both rollers 9 and 10 in the horizontal path section, the swing table 5 and the conveyed object support stand 7 are in a stacked state with respect to the cart main body 3 in a horizontal position. Thus, the object supporting table 7 can be made horizontal. In addition, in the descending path portion shown in FIG.
, thereby making it possible to horizontalize the conveyed object support table 7 together with the rocking table 5 even though the cart main body 3 is inclined. Furthermore, in the ascending path section shown in FIG.
Acting on the cam rail 21, the conveyed object support stand 7 is moved upward around the second left-right axis 6, and thereby the conveyed object support stand is moved even though the trolley body 3 and the swing table 5 are inclined. 7 can be made horizontal.
