Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier device using a self-propelled body used for supporting and carrying a body in, for example, an automobile manufacturing factory.

2. Description of the Related Art As a device for supporting and carrying the body of an automobile, which is an example of an object to be carried, there is provided a carrying device disclosed in Japanese Utility Model Laid-Open No. 63-39070. This transporting device is provided with a trolley device supported and guided by a pair of left and right truck rails, a workpiece support device is provided on an upper part of the trolley device, and a passive protrusion is provided at a front end. A guide rail is arranged from the lower side to the side of the rail for the carriage, and a roller chain type endless rotating body supported and guided by the guide rail is provided, and the passive protrusion is provided at a plurality of positions of the endless rotating body. It has a drive projection that can be engaged and disengaged.

According to this conventional type, by engaging the drive projection with the passive projection, the moving force of the endless rotating body is transmitted to the trolley device,
As a result, the body supported through the receiving tool of the transported object support device can be transported on a fixed path. A similar transport device is also provided in Japanese Patent Laid-Open No. 59-107846.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above-mentioned conventional type, there are a plurality of types of bodies to be conveyed via the supporting device. Therefore, after stopping the empty trolley device at the body loading place, the body is to be loaded depending on the type of vehicle to be loaded. As a result, manual work such as replacement and placement of the receiving tool must be performed, and the working time for that purpose reduces the overall efficiency. Also, when the trolley device is stopped by separating the drive protrusion from the passive protrusion, the stop position is constant, so a structure such as body positioning and operation time are required on the body supply device (lift device etc.) side. And, special piping and wiring were required.

The object of the present invention is to make the arrangement of the receivers optimal for the model of the article to be loaded when it arrives at the loading location of the article, and to adjust the stop position arbitrarily. In addition, it is possible to provide a carrier device using a self-propelled body that does not require special piping and wiring.

 Next, the operation of the above embodiment will be described.

The self-propelled body 4 travels on the transport path 5 while being supported and guided by the guide rail 1 by rotating the pinion 15 by the traveling drive device 12. At that time, the wheels 8, 23, 29 are supported and guided by the upper surface of the plate body 1B, and the floating prevention rollers 9, 24, 30 are provided.
Is guided by the lower surface of the plate body 1B and the lateral deviation prevention rollers 10, 25, 31 are guided by both side surfaces of the pipe body 1A, so that the self-propelled body 4 travels stably.

When the empty self-propelled body 4 comes in front of the body loading place 54, the body 53 to be loaded next from the control unit 55 provided at the body loading place 54 or the central control unit (not shown). The vehicle type signal (model information) is given to the control panel 21 of the running vehicle 4 via the rail group 19 and the transfer device 20. This control panel 21 is currently equipped with respective receiving members 35A, 35B, 42A, 42B,
It remembers which vehicle type the 43A, 43B, 49A, 49B are in, and therefore, when the vehicle type signal is met, the self-propelled body 4 is put into the body loading place 54 without any operation.

If it is different from the vehicle type signal, it is operated so as to match the vehicle type signal and then placed in the body loading place 54. That is, the operation of the gear motors 44, 55 causes the rotating shafts 38A, 3
Rotate 8B, 39A, 39B forward and backward to move each rear movable support 42A, 42B,
43A and 43B are erected as shown by the solid line in FIG.
As shown by the phantom line in the figure, it is laid down sideways. In this way, the self-propelled body 4 is put in the body loading place 54 in the receiving posture corresponding to the vehicle type signal.

When the above-mentioned self-propelled body 4 travels as described above, the power supply and the signal transmission / reception to / from the self-propelled body 4 are performed by the rail group 19 by the transfer device 20.
Is performed by sliding contact with the ground control unit and control panel.
Signals are exchanged with 21 to stop, control traveling, and confirm seating.

The empty self-propelled body 4 in which each of the receiving members 35A, 35B, 42A, 42B, 43A, 43B, 49A, 49B is adjusted to match the vehicle type signal stops at the body loading place 54. And the body via the transfer device 56
53 is loaded, and at that time the transfer device 56
On the other hand, when the body 53 is displaced, the stop position of the self-propelled body 4 is corrected in the front-back direction (travel direction) with respect to the displaced body 53. As a result, the self-propelled body 4 can be correctly opposed to the body 53, and the desired loading is performed.

At this time, the front receiver 35A, 35B serves as a reference point, and either one is used according to the vehicle type. In the rear part, the rear movable receivers 42A, 42B that have been erected, the rear movable receivers 43A, 43B that have been erected, and both rear movable receivers 42A, 42B, 43A, 43B.
The receiving posture by the rear fixed receivers 49A and 49B in a state of being laid down is selected and used. In some vehicle models, the rear fixed receivers 49A, 49B become an obstacle when using any of the rear movable receivers 42A, 42B, 43A, 43B, but at this time, the front end receivers 49a, 49b are springs. You will be forced to retreat.

EFFECTS OF THE INVENTION According to the present invention having the above-described configuration, the self-propelled body collects power and transmits / receives signals to / from the ground side via the power supply / control signal transmission / reception rail group and the transmission / reception device. It can be guided and run, and stopped at the desired location. Then, the rear movable receiver is erected or laid down sideways via the actuating device and combined with a fixed front receiver or the like, so that it is possible to always stably support the conveyed objects of various models. At that time, in front of the place to load the transported object, the above-mentioned signal transfer configuration gives the control panel the model information according to the model of the transported object to be loaded, so that the working device can be operated quickly. The rear movable receiver can be erected or laid down, and when this self-propelled body stops at the place where the transported object is loaded, it can be ready to receive the corresponding transported object, and thus can immediately move to the loading work, The overall work can be streamlined. Immediately after stopping, the self-propelled body can be moved forward or backward depending on the supply position of the transported object, so that even if the supply position is disturbed, the self-propelled object can be corrected. On the (supply device) side, it is possible to dispense with a positioning device for the transported object, operation time, and special piping and wiring.
