Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work transfer device for performing work such as drilling or welding.

[0002]

2. Description of the Related Art Conventionally, a traveling crane is used to transfer a work for performing work such as drilling or welding or the like from a parallel first transport path to a second transport path.

[0003]

When transferring using a traveling crane, there is a problem that it takes a great deal of time to hook the wire. In particular, when the work becomes long, there are problems that the number of places for hanging wires increases and that skill is required for selecting the places for hanging wires.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a work transfer device capable of transferring a work very easily and quickly without the need for wire hanging.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to a bogie that travels forwards and backwards, roller conveyors arranged side by side on both sides of the bogie, and between both ends of the bogie in the traveling direction. A work transfer device including a plurality of parallel telescopic arms provided to extend and contract at a required position on the carriage and between rollers of a roller conveyor, and an elevating device provided to elevate the bogie side of each telescopic arm. It was adopted.

[0006]

After the work is fed to the head side of one roller conveyor, the telescopic arm is extended from the top of the carriage between the rollers of the one roller conveyor.

Next, the work on one roller conveyor is loaded (transferred) onto the telescopic arm while the telescopic arm is raised by the action of the lifting device.

Then, after the telescopic arm is contracted to draw the work onto the carriage, the telescopic arm is extended toward the other roller conveyor and the work is projected above the other roller conveyor.

After that, the telescopic arm is lowered by the action of the elevating device, and the work is placed (transferred) on the other roller conveyor. The telescopic arm descends between the rollers of the roller conveyor.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 shown in FIGS. 1 and 2 denotes a bogie that travels forward and backward. In the traveling of the cart 1, the wheels 3 get on the rails 2 and the wheels 3 are driven by the first motor 4 to be self-propelled.

Roller conveyors 5 and 6 are provided in parallel on both sides of the traveling path of the carriage 1.

Further, a plurality of telescopic arms 7 which are fitted between the rollers of the roller conveyors 5 and 6 in parallel with each other are provided in parallel at a required position between both ends in the traveling direction on the carriage 1, and The retractable arm 7 is moved up and down by a bobbin lifting device 8 on the trolley 1 side.

As shown in FIGS. 1 to 8, the elevating device 8 for the telescopic arm 7 is a rectangular vertical frame of the frame 11 by holding rollers 10 supported by brackets 9 at four positions on the front, rear, left and right of the carriage 1. When the rod member 14 is slid forward by the contracting action of the first cylinder 13 installed on one end side of the truck 1 while hugging the rail member 12, the rod 14 is moved to the first position.
Since the first shaft 16 connected via the projecting piece 15 rotates clockwise in FIG. 4, one side of the frame 11 connected via the link 18 to the second projecting piece 17 projecting from the first shaft 16 is pushed up. , The first gear 19 of the first shaft 16 and the second shaft 20
The second projection 21 is engaged with the second projection 20, and the third projection 22 protruding from the second shaft 20 is rotated together with the second shaft 20 in the counterclockwise direction in FIG. 5, so that the third projection 22 is connected to the third projection 22 via the link 23. The other side of the frame 11 is pushed up. In addition, in order to lower the frame 11, the first cylinder 13
Should be extended.

The telescopic arm 7 is provided with grooved guide rails 24 whose upper ends are open and fixed to the frame 11 with both ends positioned on both sides of the carriage 1. The guide arms 24 are dropped into the guide rails 24 from above and the upper and lower arms are held. Included and bottom support roller 2
5, a groove-type first slider 26 whose upper surface is open to ensure smooth horizontal sliding, and a groove 25 which is dropped into the first slider 26 from above, and, like the first slider 26, smoothly slides horizontally. In combination with the second slider 27 having a flat upper surface for ensuring the above, the second motor 28 installed on the carriage 1 rotates the third shaft 29 in the forward and reverse directions, and then the carriage 1 moves to both sides in the traveling direction.
And one of the four sprockets 30 arranged above and below the middle of the four sprockets 30 while driving one of them.
The four sprockets 30 are synchronously rotated while running the chain 31 spanned between them, and the first pinion 33 driven from one of the sprockets 30 via the fourth shaft 32.
The first rack 34 provided on the entire length of the lower surface of the first slider 26.
, The first slider 26 slides. At this time, the second slider 27 and the first slider 26
The second slider 35 and the third rack 36, which are provided along the entire length of the opposite surface to, are supported by the first slider 26 (shown in FIG. 4).
Since the second pinion 37 is meshed, the second slider 27 slides in the same direction.

With the above construction, the operation of one of the roller conveyors 5 is stopped, and the carriage 1 is horizontally mounted on the work.

Next, the first motor 28 is operated to drive the first motor.
When the pinion 33 is normally rotated, the first slider 26 slides in the extending direction.

At this time, the second slider 27 also slides in the extending direction due to the meshing of the second rack 35 and the third rack 36 with the second pinion 37, and the first slider 26 between the rollers of the one-side roller conveyor 5, Second slider 27
Pierces.

Next, when the rod 14 is slid forward by the contraction action of the first cylinder 13, the first shaft 16 rotates via the first projecting piece 15, so that the second projecting piece 17 and the link 1
One side of the frame 11 via the first gear 16, the second gear 21, the third protrusion 2 with the rotation of the first shaft 16.
2. The other side of the frame 11 is pushed up via the link 23.

As a result, the telescopic arm 7 ascends together with the frame 11, and the work on the one-side roller conveyor 5 is received on the telescopic arm 7.

Thereafter, the second motor 28 is operated to reversely rotate the first pinion 33 to slide the first slider 26 and the second slider 27 in the contracting direction, and then to the other roller conveyor 6 in the above-mentioned first direction. 1 slider 2
6 and the second slider 27 are projected.

However, when the frame 11 is lowered by the extension action of the first cylinder 13, the first slider 26 and the second slider 27 are lowered from between the rollers of the other roller conveyor 6, so that the other one of the roller conveyors 6 is lowered. The work on the telescopic arm 7 is received on the roller conveyor 6.

After receiving the load, the first slider 26 and the second slider 27 are shrunk so as to fit on the carriage 1.

If a telescopic arm 7 with an elevating device 8 is provided on each trolley 1 and the number of trolleys 1 is increased or decreased depending on the length of the work to be connected, the work length is related. Work can be transferred without the need.

[0025]

As described above, according to the transfer device of the present invention, the work can be transferred extremely easily and quickly from one roller conveyor to the other roller conveyor through the telescopic arm with the lifting device arranged in parallel. be able to. For this reason, it is possible to eliminate the problem that the efficiency of the work and the processing, which is caused by the troublesome wire hooking during the transfer by the crane, is significantly reduced.
