Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for centering an automatic glass plate lifting device.

Generally, when bending a glass plate, the upper end of the glass plate is held by a hanging tool and carried into a heating furnace, and the glass plate is heated to near its softening point and then press-formed. In this case, the glass plate is positioned, a paste-like substance is applied to a predetermined location on the top edge of the glass plate to prevent seizure and slippage, and then multiple locations on the top edge of the glass plate are hung using multiple hanging tools. However, when holding the glass plate, the hanging tool must securely hold the part of the paste-like substance applied to the glass plate surface for the purpose of preventing seizure and slipping, and all The hangers shall be aligned along the top edge of the glass pane. Previously, the work of suspending glass plates using multiple hanging tools had to be done manually.
It was inefficient.

Therefore, an automatic lifting device that automatically performs this work has been proposed, but this device includes a plurality of hanging tools and a plurality of hanging tools arranged above the glass plate and along the length of the glass plate. The glass plate was suspended and supported by a swingable support plate, each of these hanging devices was lifted and the chips were aligned in an open state, and a paste-like substance was applied to the glass plate hanging device using a coating device. After that, the glass plate is lifted and its upper end is interposed between each chip of the hanging tool, and the glass plate and the hanging tool are lowered synchronously, so that the glass plate is suspended from the hanging tool. This is what I did.

By the way, the paste-like substance is applied to prevent the tip of the hanging tool from slipping between the glass and the tip from fusing to the glass plate, and therefore, the paste-like substance is applied to the glass plate. The position and hanging position must match accurately.

However, due to the bending of the hook bar, which suspends and supports the hanging tools via turnbuckles and supporting plates arranged in a tournament shape, it is actually difficult to accurately adjust the paste-like material application position and hanging position of the glass plate. It is extremely difficult to match them.

The present invention has been made in view of the above circumstances.
The purpose is to center all the hanging tools before hanging the glass plate, and to match the paste-like material application position on the glass plate with the hanging position with high precision.
It is an object of the present invention to provide a method for centering an automatic glass plate lifting device, which enables stable initial lifting work.

In order to achieve such an object, the present invention suspends and supports a plurality of hanging tools by a turnbuckle and a plurality of swingable support plates arranged above the glass plate and along the length of the glass plate. , lift each of these hanging tools and line them up in an open state, apply a paste substance to the suspended position of the glass plate using a coating device, then lift the glass plate and place the chips on the hanging tools. In an automatic glass plate lifting device that suspends a glass plate by interposing its upper end between each chip and lowering the glass plate and a hanging tool synchronously, the turnbuckle is moved to a predetermined position.

Next, the glass plate W is placed on the supports 7B, 7B provided at the lower part of the inner frame 4, and then the movable supports 7B, 7B, 7L are driven.
The glass plate W has an immovable support part 7U as a stopper,
7U, 7R, and when the edge of the glass plate W comes into contact with these immovable support parts, the glass plate W is moved until it comes into contact with all the support parts 7U, 7U, 7B, 7.
It is fixedly set in a predetermined position with high precision by B, 7L, and 7R.

After the glass plate W is fixedly set on the inner frame 4 in this way, the cylinder unit 5 is driven again to return the inner frame 4 to the vertical position.
The glass plate W is also set vertically.

Thereafter, the cart 8 is moved forward to approach the rear of the glass plate W, and while the glass plate W remains supported by the inner frame 4, the attachment/detachment mechanism 9 provided on the cart 8 is driven to remove the upper edge of the glass plate W. is held, and the lower edge of the glass plate W is supported by the support mechanism 10, so that the glass plate W is also supported on the cart 8 side. That is, the arm members 28, 28 are waiting in an open state above the glass plate W, and from this state, the cylinder unit 22 is driven and its piston rod 22b is moved.
When the arm members 28, 28 are moved downward, first, the arm members 28, 28 descend until their gripping portions 28a, 28a are located on both sides of the upper end of the glass plate W. When the piston rod 22b is further moved downward, the claw body 30 moves downward and engages the engagement groove 28b, closing the arm members 28, 28, thereby causing the gripping portions of these arm members 28, 28 to close. 28a, 28a are in close contact with both surfaces of the glass plate W, as shown, and support the upper end of the glass plate W.

On the other hand, the air cylinder unit 33 is driven to move the support 35 upward, and the support piece 34 provided thereon is moved upward.
After contacting the lower edge of the glass plate W, the electromagnet M is operated to attract and fix the suction plate 36, so that the lower edge of the glass plate W is supported by the support 35.

After that, if all the supports 7U, 7U, 7B, 7B, 7L, and 7R provided on the inner frame 4 side are released, the glass plate W is attached to the inner frame 4.
From there, it is delivered to the trolley 8 while maintaining the same state.

The glass plate W thus delivered to the cart 8 is lifted upward as it is, and a paste-like substance is applied to predetermined locations on both sides of the glass plate W by a coating device 19 waiting above, and then the entire glass plate W is returned to its original state. lower to position.

Incidentally, the application of the paste-like substance is performed as follows. That is, in FIG.
5 to rotate the cam plate 47,
The push rod 42 is moved down via the cam follower 44 that comes into contact with this, and the link members 52, 5
2 is further deformed into a sharp V shape, and due to this deformation, the sliding members 50, 50 and the supporting members 53, 53 move inward, and the chips 56 and 56 supported by the supporting members 53, 53 are separated from each other by the glass plate. It comes into contact with predetermined locations on both sides of the W, and the paste-like substance flowing out from the chips 56, 56 adheres to the contact locations. Thereafter, when the cam plate 47 is driven to move the push rod 42 upward, the chips 56, 56 are separated from the glass plate W, and the paste-like substance is reliably applied to both sides of the glass plate W.

Meanwhile, at the same time as the coating operation, the centering mechanism 1
20 operates to set all the hanging tools 60...into predetermined positions. That is, all the hanging tools 60... are initially located below the predetermined position. When the cylinder unit 123 is driven to move the hook 121 upward, the tapered groove 121a of the hook 121 is tightly fitted into the tapered hole 102a of the turnbuckle 102, and the turnbuckle 102 is then lifted to a predetermined height and suspended. Set the lower fittings 60... in a predetermined position. At this time, since both turnbuckles 102, 102 and the hook bar 101 are insulated, the hanging tool 60...
is set at a predetermined position with extremely high precision, regardless of the deflection of the hook bar 101. Mata hook 12
〓〓〓〓
Since the taper groove 121a of No. 1 is tightly fitted into the taper hole 102a of the turnbuckle 102, the turnbuckle 102 is positioned in the front-back direction (left-right direction in FIG. 8) at the same time as the fitting, and both turnbuckles 102, 102 are on the same plane As a result, all the hanging tools 60... are also arranged on the same plane.
