Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a transfer device for transferring motorcycles between lines.

(Prior art) In the assembly line for small two-wheeled vehicles,
Up until now, a front wheel positioning jig for positioning the front wheel of a motorcycle and an engine positioning and mounting jig, which also serves to position the center stand, have been run on the line, and the process from joining the engine and frame to the final process has been carried out on the line. I tried to do all the assembly work.

However, on such an assembly line, even though the engine positioning and mounting jig is not required after the engine is connected, this jig also serves as the positioning of the center stand, so this jig is placed on the line unnecessarily. In addition, the number of jigs required will be increased accordingly, and costs will be wasted when dealing with new species.

Of course, in order to eliminate this inconvenience, it would be best to separate the line from the engine assembly to the final process and reduce the number of engine mounting jigs to the minimum necessary. In addition to requiring a complicated transfer device to transfer small motorcycles to another line, another problem arises in that the transfer device requires a lot of manpower and time.

(Purpose) The present invention has been made in view of these problems, and its purpose is to provide a device with a simple structure that requires almost no work for transfer.

(Means for Achieving the Object) That is, the present invention is a device for achieving the object, in which a frame suspension support that can be moved up and down, which runs so as to connect two assembly lines, has a frame suspended at the front end.
A handlebar suspension body is provided, which consists of a supporting piece that can swing upward to take a supporting position facing forward in the running direction of the line, and a retaining member that moves up and down to restrain and release the handlebar on the supporting piece. At the same time, a frame rear end holder having a support portion facing the running direction of the line and swingable back and forth is disposed at the rear end of the frame suspension support.

(Example) The details of the present invention will be explained below based on the illustrated example.

FIG. 1 shows an embodiment of the present invention, and this device consists of an engine coupling line L ₁ , that is, an engine coupling line L in which a front wheel positioning jig J ₁ and an engine and stand positioning jig J ₂ flow alternately. ₁ and the frame assembly line, that is, the front wheel positioning jig J ₁
and the frame assembly line _L2 , which alternately runs the stand positioning jig _J3 .

Reference numeral 1 in the figure is a horizontal beam installed on this contact point, and on the bottom surface of this beam 1, a main rail 4 and a rack rail 5 are installed below via a beam 3 which also serves as a storage area for the cable carrier 2. It is attached at both ends by brackets 6 and 7 which also serve as stoppers.

Reference numeral 9 denotes a running body that runs on this main rail 4. A pinion (not shown) is meshed with the rack rail 5, and the running body 9 is configured to run back and forth by being driven by a drive motor 10.

Reference numeral 12 denotes a lifting mechanism suspended below the traveling body 9 via a coupling fitting 13. Here, a link body 14 that horizontally supports a frame suspension rod 18 at the lower end is connected via a parallelogram link 15. It is mounted so that it can be moved up and down by a drive motor 16.

FIG. 2 shows the suspension rod 18. Arms 19 extending left and right are integrally fixed to the tip of the suspension rod 18, that is, to the front end in the running direction of the conveyor. A suspension body 21 for suspending the handlebar _w1 of the frame w is attached in a position adjustable manner, and a frame rear end suspension body 43 for hanging the hook _w2 at the rear end of the frame is attached to the rear end of the suspension support rod 18. is pivoted so that it can swing back and forth.

FIG. 3 shows details of the above-mentioned handlebar suspension body 21, in which a pair of slide rails 22 are provided along the upper and lower surfaces of the end of the arm 19 fixed to the tip of the suspension rod 18. 23 are integrally attached by screws 25, 25, and sliders 26, 26 are swingably attached to these, respectively. One of the vertical rods 28 that restrains the handlebar _w1 of the two-wheeled vehicle w is connected to the upper and lower arm rods 29,
It is integral with these sliders 26, 26 via a lower arm 30 and slider 26 is connected to the lower arm 30.
The pin 31 is inserted through the slide rail 23 so that the pin 31 is always projected upward by the biasing force of the spring 32, and its tip is engaged with a plurality of positioning holes 24 bored at intervals on the lower surface of the slide rail 23. In this way, the handlebar is positioned according to the length of the handlebar.

On the other hand, a fulcrum pin 34 is inserted into the lower end of this vertical rod 28, and a handlebar support piece 36, which is always held horizontally and facing forward by a stopper 35, is rotatably movable upward. At the tip of the upper arm 29 which is pivotally supported and projects forward of the stem 28, a retaining rod ₃₈ is provided at a distance sufficient to allow the handlebar w1 to be inserted between the stem 28 and the stem 28. The rod 38 is attached so as to be able to swing up and down, and as shown in FIG. The handlebar _w1 is configured to be restrained and released by moving up and down.

On the other hand, FIG. 5 shows a frame rear end holder 43 of the suspension rod 18, which is attached to an upper rod 45 which is pivotally supported at the rear end of the suspension rod 18 via a pin 44. and a lower rod 46 provided with a forward-facing hook 47 at its lower end.
It is configured to be able to swing back and forth by a cylinder 50 attached via 7 and 48.

Next, the operation of the above-described device will be explained.

When the frame is locked in the final step A of the engine coupling line _L1 , the frame suspension support rod 18, which was waiting just above it, descends with the frame rear end holder 43 tilted backward, and first suspends the handlebar. The support piece 36 of the base body 21 is brought into contact with the handlebar w ₁ and rotated upward about the pin 34 at the lower end of the stem 28 as a fulcrum, while the handlebar w ₁ is moved between the stem 28 and the retaining rod 38. accommodated between
At the same time, the cylinder 50 at the rear end of the hanging holder 18 is contracted to lower the frame rear end holder 43, and the hook _w2 at the rear end of the frame is hooked by the hook 47 provided at its lower end.

Then, in this state, the lifting mechanism 12 is operated to raise the suspension rod 18, and the frame w supported by the suspension body 21 and the hanging body 43 is pulled up.
Next, in this state, the traveling body 9 is run to the end B of the main rail 4, and at that position, the frame suspension support rod 18 is lowered to place the suspended frame w between the front wheel positioning jig _J1 and the stand positioning jig. Place it on J ₃ . And finally, the handlebar suspension body 21
Activate the upper cylinder 39 and remove the retaining rod 3.
When you pull up 8, the handlebar is released.
W ₁ comes off from the handlebar hanging holder 21 as the frame w starts to move with the conveyor, and at the same time, the hook w ₂ at the rear end of the frame w also comes off from the hook 47 of the hanging holder 43 and goes directly to the line L. ₂
Go with the flow.

(Effects) As described above, according to the present invention, the front end of the frame hanging support that travels between lines and moves up and down has a supporting piece that can swing upward and takes a supporting position facing the running direction of the line. A swingable handlebar suspension body is provided which includes a retaining member that moves up and down to restrain and release the upper handlebar, and a support portion facing the running direction is provided at the rear end of the frame suspension support. Since a frame rear end hanging support is provided, the handlebar and the frame rear end can be supported by simply lowering the frame suspension support onto the frame, and after the frame is placed on the transfer line. By simply raising the retaining member, the frame can be removed by moving the line, making it possible to greatly reduce the effort and time required for transfer, as well as the transfer device itself. It can be constructed more simply with fewer moving parts.
