Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an automobile window glass conveying device.

<Prior Art> In order to assemble the windshield glass to the car body, the windshield glass is automatically conveyed one by one from the windshield stock position to the car body conveyance line.

As shown in FIG. 7, the conventional window glass conveyance device has a conveyor 2 suspended on a running rail 1 so that it can run, and a conveyor 3 equipped with a suction pad 4 using air that can be moved up and down. The structure is such that the window glass W is suctioned by the suction pad 4 and conveyed to a predetermined location.

<Problems to be solved by the invention> In the conventional device described above, the air hose 6 connecting the negative pressure air source and the suction pad 4 and the air hose routing for expanding and contracting this air hose as the conveying device 3 moves. In addition, it is necessary to provide a movable net 8 to prevent the window glass W from falling when the air is cut off, an actuator 9 for opening and closing the movable net 8, and a transport path for the window glass W. It requires a permanent fall prevention/inspection net 7, etc., which is difficult to transport over long distances, and there are problems in terms of space and cost due to ancillary equipment.

<Means for Solving the Problems> The present invention was proposed to solve the above-mentioned conventional problems, and its main structure is to install a hanger that is movably suspended from a traveling rail and attached to a conveyor. An arm support is provided so that it can be raised, lowered and rotated by a lifting device and a rotation device, and two pairs of hanger arms curved in a substantially C shape are supported on the hanger arm support so as to be openable and closable by a hanger arm opening and closing device. , a window glass receiving piece is provided at the tip of the hanger arm to support the window glass in a flat state when the hanger arm is closed;
The hanger arm support is provided with a window glass presser piece that elastically presses the upper surface of the window glass supported on the window glass receiver piece.

<Function> The present invention supports and receives the window glass on the lifter with the window glass receiving piece by closing the window glass lifted by the lifter from the open state of the hanger arm, and at the same time, the window glass on the lifter is supported and received by the window glass receiving piece. The window glass presser presses the top surface of the window glass to hold the window glass on the hanger arm and transport it to a predetermined position.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3. 10 is a running rail. A transport machine 11 that can be automatically moved by a running motor 11a is suspended from the running rail 10.
The carrier 11 is provided with a hanger arm support 12 that can be moved up and down and rotated. Its specific structure is as follows. A rack shaft 13 extending in the vertical axis direction passes through the conveyor 11 so as to be able to move up and down, and a support plate 26 is fixed to the lower end of the rack shaft 13 . A lifting motor 16 and a gear device 17, which is driven by the lifting motor 16 and moves the rack shaft 13 up and down, are disposed on the conveyor 11.
14 indicates a stopper.

A vertical support shaft 15 is rotatably supported on the support plate 26, and the hanger arm support 12 is fixed to the support shaft 15. A sprocket 19 is fixed on the support shaft 15, and is connected to a rotation motor 18 fixed to the hanger arm support 15 by a chain.

On the hanger arm support 12 which can be raised and lowered and rotated, two pairs of hanger arms 20 which are curved in a substantially C shape are supported so as to be openable and closable by a support shaft 21 facing each other, and are fixed to the hanger arm support 12. The hanger arm opening/closing motor 22 and the support shaft 21 are linked together.

At the tip of the hanger arm 20, there is a window glass receiving piece 2 that supports the window glass W in a plane.
3 is provided and also a hanger arm support 12
is provided with a window glass presser piece 24 biased downward by a spring 25 to press the upper surface of the window glass W supported on the window glass receiver piece 23.

The present invention having the above configuration allows the window glass W to be closed by closing the hanger arm 20 from the open state.
is supported on a window glass receiving piece 23, and at the same time the upper surface of the window glass W is pressed by a window glass holding piece 24 to hold the window glass W on the hanger arm 20 in a clamped state. Then, the transport device 11 travels along the travel rail 10 to transport it to a predetermined position.

An example of this conveyance operation will be explained with reference to FIGS. 4 to 6. In FIG. 4 and FIG. 5, 30 is a lifter, and a transfer conveyor 31 installed on the floor.
It receives the window glass W and ascends to the conveying device of the present invention suspended from the traveling rail 10. As shown in FIG. 6, this lifter 30 is provided with a glass receiving piece 32 that supports the window glass W.

Reference numeral 10b is a running rail that is disposed perpendicular to the running rail 10 and guides the transport device to the position of the body B of the automobile. A direction change rail 10a is arranged at the intersection of this traveling rail 10b and the traveling rail 10, and is connected to the traveling rails 10, 10b to guide the conveying device.

Therefore, the lifter 30 that is being lowered by the transfer conveyor 31 is made to support the window glass W.
It will rise to the rising end as shown in the figure. On the other hand, the conveyance device moving to the ascending end portion of the lifter 30 is
The hanger arm 20 is kept open and on standby.

When the lifter 30 stops at the rising end,
The window glass holding piece 24 comes into contact with the upper surface of the window glass W supported by the glass receiving piece 32 on the lifter 30 side, compresses the spring 25, and moves upward together with the window glass W.
The elastic force is applied in the downward direction. After the lifter 30 stops at the ascending end, the hanger arm 20 closes, and then the lifter 30 begins to move downward toward the descending end. At this time, the window glass W supported by the glass receiving piece 32 of the lifter 30
is delivered to the window glass receiving piece 23 on the hanger arm 20 side, and the window glass W is held by the hanger arm 20 in a clamped state by the pressure of the window glass holding piece 24.

Next, the transport machine 11 starts traveling, travels on the travel rail 10, and stops at the direction change rail 10a. Then, the direction change rail 10a is rotated by 90 degrees, connected to the traveling rail 10b, and the conveyor 11 starts running again, traveling along the traveling rail 10b to the position of the body B of the automobile and stopping. At this stop position, the hanger arm 20 is moved downward and the window glass W is rotated in a direction that facilitates assembly, and the operator receives the window glass W from the hanger arm 20 and assembles it to the body B. It is. After the operator receives the window glass W, it is returned to the lifter 30 in the reverse order of the above operations.

<Effects of the invention> As described above, according to the invention, since the window glass is supported by a hanger arm that opens and closes, there is no need for an air hose or a rail for managing it unlike in the conventional air suction pad mechanism, which saves space and costs. Not only does this solve the problem, but long-distance transport and transport routes can be freely set.

Furthermore, since the window glass is configured to be flatly supported in the closed state by the receiving pieces provided at the tips of two pairs of hanger arms that can be opened and closed and are curved in an approximately C shape, the size of the window glass can be adjusted. It is versatile enough to be supported without adjustment even if the size is changed, and it is held in a clamped state by a window glass holding piece that elastically presses the top surface of the window glass supported by this hanger arm. As a result, unlike the conventional air suction pad mechanism, the falling of the window glass due to air shortage etc. is reliably prevented, eliminating the need for additional equipment for fall prevention nets, which also solves problems in terms of surrounding space and cost. In addition, since air is not used, it has the effect of saving energy.
