Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving bolster provided in a press and a cable handling device for a traveling trolley for processing a cable for supplying power to a trolley for transporting molded articles (hereinafter referred to as a traveling trolley). .

[0002]

2. Description of the Related Art Conventionally, a traveling carriage provided in a press or the like travels on a traveling rail laid in or around the press, and travels by a traveling motor. Cables are connected. Further, when the traveling trolley is a moving bolster, since the cable is pulled out of the press body and then moved in the Y-axis direction orthogonal to the pulling-out direction (X-axis), the crossing is performed. The following cable treatment is performed. (1) A cable reel is provided on the floor of a traveling vehicle or a track on which the traveling vehicle travels, and processing is performed by feeding or winding a cable as the traveling vehicle moves. (2) The pulley that digs a pit on the floor and bypasses the cable is dropped by its own weight, and the cable is fed and wound up as the traveling vehicle moves. (3) Electricity is supplied to the rails or an overhead line is laid above the track to receive power from the rails or the overhead line.

[0003]

However, in the processing method (1), the cable is extended on the floor surface or several tens cm from the floor surface on the track as the traveling vehicle moves. There are problems such as obstructing the passage of other vehicles and people. In the above method (2), the pit must be excavated on the floor, which requires a large amount of work. In addition, when another bogie on which the products are stacked runs on the pit, the load collapses due to unevenness of the floor surface. There is a defect that causes Furthermore, in the method (3), there is a danger that there is a danger of electric shock because the live line is on the floor, and that a cable hanging from the overhead line hangs and interferes with peripheral equipment. The present invention has been made for the purpose of improving the above-mentioned problems, and an object of the invention is to provide a cable handling device for a traveling vehicle that does not interfere with traveling or interfere with peripheral equipment.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention crosses a traveling rail laid in the front-rear direction of a press body and a traveling rail laid perpendicular to the traveling rail. A guide rail and a power supply line are erected above the travel carriage in parallel with the travel rail, and a duct support is movably mounted on the guide rail, and is vertically suspended from the duct support. A cable whose one end is connected to a power supply line via a current collector is inserted into the duct, and the lower end of the vertical duct and the traveling vehicle are connected by a cable bearing. The end side is drawn into the traveling vehicle.

[0005]

[Operation] With the above configuration, even if the traveling vehicle is moved in and out of the press body, the cable bearings connected between the lower end of the vertical duct and the traveling vehicle are folded and stored in the traveling vehicle, which hinders traveling. Never be.

[0006]

[Embodiment] An embodiment of the present invention will be described in detail with reference to the drawings. 1 is a side view showing a state in which a traveling trolley such as a moving bolster is pulled out of the press body, FIG. 2 is a plan view of the same, FIG. 3 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. It is an arrow view from the B direction. In these figures, reference numeral 1 denotes a press body, which has a traveling carriage 2 which can be moved in and out.
The mold 3 is mounted on the traveling vehicle 2. The traveling vehicle 2 has wheels (not shown) at the bottom, and is provided with a traveling rail 5 laid in the front-rear direction of the press body 1 from the inside of the press body 1 and a right and left direction of the traveling rail 5 before and after the press body 1. A power supply cable 8 and one end of a cable bearing 9 supporting the power supply cable 8 are connected to a terminal box 7 provided on the traveling carriage 2. I have.

The cable bearing 8 is formed of two rows of chains 10 that are bendable in one direction, and the cables 8 are supported by pins 11 laid between the chains 10. A pit 13 is formed along the running rail 5 near the running rail laid in the front-rear direction of the press body 1, and a plurality of rollers 14 are arranged in the pit 13 as shown in FIG. It is rotatably supported in the presence of. These rollers 14 support the cable bearings 9 moving in the pit 13 from below when the traveling carriage 2 is moved in and out of the press body 1.

On the other hand, reference numeral 16 in the figure denotes a guide rail supported by an upright 17 of the press body 1 via a mount 18, and is provided along and along a traveling rail 6 laid in front of the press body 1. A duct support 19 is attached to the lower part of the guide rail 16 so as to run freely.
The duct support 19 has a plurality of rollers 20, which are movable along the guide rail 16 by the rollers 20, and a vertical duct 21 is suspended from the duct support 19.

The other end of the cable bearing 9 is connected to the lower end of the vertical duct 21, and the other end of the cable 8 extended from the cable bearing 9 passes through the vertical duct 21 to support the duct. It is disposed on the body 19 and is connected to a current collector 22 provided on the duct support 19. The current collector 22 is attached to the tip of an arm 23 urged upward by an urging means, and slidably contacts a power supply line 24 laid along the guide rail 16.

Next, the operation will be described. When the traveling carriage 2 is accommodated in the press body 1, the cable bearing 9 is extended in the pit 13 as shown in FIG. The current is supplied from the current collector 22 connected to the electric wire 24 to the traveling vehicle 2 via the cable 8. When the traveling carriage 2 is pulled out from the press body 1 as shown by a solid line in FIG. 1 by exchanging a mold or the like, the cable 8 and the cable bearing 9 are folded into a substantially U-shape and stored in the traveling carriage 2. Therefore, when the traveling vehicle 2 pulled out of the press body 1 is cross-traveled along the traveling rail 6 in this state, the duct support 19 is also moved along the guide rail 16 as the traveling vehicle 2 travels. Power can be supplied to the traveling vehicle 2.

In the embodiment described above, the moving bolster provided on the press body 1 is used as the traveling carriage 2, and the moving bolster requires a communication cable for transmitting a signal in addition to a power cable. If wireless, the communication cable can be omitted.

[0012]

According to the invention, as described in detail above, a cable bearing is connected to a vertical duct suspended from a duct support, and a cable is drawn into a traveling vehicle via the vertical duct and the cable bearing. Therefore, it is not necessary to install guide rails for guiding duct supports and overhead lines for current collection at a high position, and it is necessary to excavate pits to accommodate processing equipment and cables on the floor Because there is no, it can be installed easily and economically. Further, when the carriage is taken in and out of the press body, the cable bearing is folded and stored at the side of the carriage, so that it does not hinder the traveling.
