Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for automatically marking a predetermined position on a plate glass, and in particular to a device for automatically marking a plate glass at a predetermined position on a plate glass that is suspended by a pair of tongs and subjected to heat treatment. The present invention relates to a plate marking device.

For example, one method of manufacturing tempered glass by heat-treating a glass plate is to suspend the glass plate to be heat-treated at a plurality of predetermined points on the upper part using tongs, carry it into a heating furnace using a banger conveyor, and heat it to a predetermined temperature. If necessary, there is a method of press forming and rapidly cooling it to make tempered glass.

However, in this manufacturing method, the tongs gripping position is
It is necessary to select the tongs so that the glass plate load acting on each tong is equal.

If the glass plate load is applied unevenly, the portion of the glass plate at the gripping position where the dog load is applied will be more deformed than at other gripping positions, resulting in loss of commercial value.

Therefore, in order to eliminate the causes of deformation as described above, conventionally, the hanging grip position of the glass plate is selected according to the shape of the glass plate, and the glass plate is placed horizontally on a mounting table and then positioned. Since markings were placed on one side, there was a risk of the product falling off during transportation due to insufficient slip prevention when it was hung with tongs.Also, because the markings were placed on one side, there would be a difference in the thermal history on both sides of the hanging point. This had the disadvantage of reducing the strength of the ridge.

SUMMARY OF THE INVENTION An object of the present invention is to provide a glass plate marking device that eliminates the above-mentioned drawbacks of the conventional apparatus and can mark a glass plate efficiently and in a stable posture.

The present invention will be described in detail below with reference to the drawings.

The device of the present invention is roughly divided into a lifting device for a glass plate in an upright position, a tilting device for tilting a glass plate on a lifting platform, and a marking device. After setting some parts, they will automatically operate in sequence.

A frame body 2 provided at the front of the lifting device frame 1 can be guided up and down by guide tubes 3 fixed to both sides thereof fitting into a guide rod 4 fixed to the frame 1. The height of the frame 2 is set to a height suitable for the size of the glass plate by connecting both ends of the chain 7, which is run between the sprocket 6 of the member 5 and the reducer 9 rotated by the bundle 8, to the frame 2. do.

A guide sleeve 10 is fixed to the front part of the frame body 2, a mounting table 12 is fixed to the upper end of the guide rod 11 fitted into the guide sleeve 10, and a pneumatic pressure plate is pivoted to the front center of the frame body 2 so as to be swingable back and forth. cylinder 1
3 is connected to the lower surface of the mounting table 12.

An L-shaped rear glass stopper 16 is fixed to an arm 15 rotatably connected to both sides of the mounting table 12 with bolts 14, and a glass holder bar 17 is attached to this.

In the glass holder, the bar 17 can be expanded or contracted to a desired length by inserting the tube 17b into the rod 1-7a fixed to the glass stopper 16 and using the screw 17c.

Front glass stoppers 18 are fixed on both sides of the mounting table 12,
The glass holder is placed against a bar 17, and the lower part of the glass plate G placed on the mounting table 12 is held between the glass stoppers 16 and 18.

With the above structure, the glass plate G can be further raised by the cylinder 13 from the frame 2 at a set height, and the upper end of the glass plate can be held between the tongs (not shown).

A vertical part of the bracket 19 fixed to the tilting device mounting table 12 is extended into the hollow part of the frame 2, and a pneumatic cylinder 20 is attached to the vertical part.
A shaft 21 that is pivotally supported to be able to swing back and forth and connected to the rod.
Both ends of the arm 15 are rotatably connected to the arm 15.

With the above structure, when the cylinder 20 expands and contracts, the arm 15 swings up and down around the bolt 14, and the glass holder is moved to the bar 1.
7 can be tilted back and forth to give the glass plate G an arbitrary inclination angle.

A pair of guide rods 22 protruding forward are fixed to the horizontal member 5 so as to be adjustable in lateral position, and the lateral position of the glass plate G is restricted with respect to the tilting movement.

Blocks 23 that can be guided back and forth on both sides of the mark punching device frame 1
is provided, and the screw shaft 24 screwed into the block is attached to the bundle 2.
5, the front and rear positions of the block 23 are determined.

A pneumatic cylinder 27 is pivotably supported vertically in the center of a channel member 26 whose both ends are fixed to the block 23, and sliding members 29 are fixed to both ends of a channel horizontal member 28 connected to the rod. A guide shaft 32 whose both ends are attached to the frame 1 with metal fittings 31 is attached to the IJ-bu 30 fixed to the
is inserted so that the sliding member 29 is slid back and forth by the cylinder 27.

Both ends of a rectangular support rod 33 are fixed to the front parts of the sliding members 29 on both sides, and a support column 35 is fixed to a pair of fittings 34 fitted thereto so as to be able to adjust the lateral position.

As will be described later, the support column 35 is inclined rearward by about 10 degrees so as to be parallel to the inclined posture of the glass plate G.

A support frame 37 of a marking machine 36 is attached to a support post 35 so that its vertical position can be adjusted.

The marking machine 36 includes a pair of rotating arms 38 that are reversibly rotated at a constant angle in opposite directions by air pressure or a motor, and have a marking stamp 39 at the tip thereof.

The marking machine 36 has a tilted position, and the temporary glass holder is positioned directly above the glass plate G leaning against the bar 17, and is moved back and forth by the cylinder 27. When the marking machine 36 is in the rear position, the rotary arm 38 opens in a substantially horizontal direction to mark the glass plate G. The stamp 39 is in a standby state protruding downward (FIG. 3).

The cylinder 27 causes the marking machine 36 to move the inclined glass plate G.
When the rotary arm 38 moves upward, the rotary arm 38 tilts about 10 degrees (to the position indicated by the chain line in FIG. 3), and the mark stamp 39 simultaneously makes marks indicating the tongs clamping point on both sides of the glass plate G.

A parallelogram link 42 is pivotally supported by upper and lower pins 41 on a support plate 40 fixed to the block 23, and the link 43
Both ends of a connecting rod 45 and a supporting rod 46 each having a square cross section are fixed to the rear end and the upper end of the vertical link 44, respectively, and a rod of a pneumatic cylinder 47 that is pivotally supported to the channel member 26 so as to be swingable back and forth is attached to the connecting rod 45. Connect to.

A pair of fittings 48 whose horizontal position is adjustable are fixed to the support rod 46, and an inverted L-shaped support 49 is fitted and fixed into the fittings 48 so that its vertical position is adjustable.

The upper horizontal portion 49a of the support 49 is located below the marking machine 36 in the standby position, and a pair of marking agent storage containers or saucers 50 which are slidable back and forth are fixed to the horizontal portion 49a directly below the mark printing 39. do.

When the handle 25 is rotated, the marking machine 36 and the saucer 50
It moves forward and backward in unison with the glass plate G, and is set at a forward and backward position suitable for the upper position of the inclined glass plate G.

Next, the present invention will be explained in detail.

The height of the frame 2, the lateral position of the guide rod 22, the height and front and rear positions of the marking machine 36 are determined according to the size of the glass plate G to be marked, and the glass plate G is automatically placed on the mounting table by hand or by a vacuum lift. 12, and the glass plate G is propped up by the cylinder 20 in a posture inclined backward by about 10 degrees.

Next, when the mark making machine 36 is advanced by the cylinder 27 and stopped above the glass plate G, the rotary arm 38 rotates downward and the mark stamps 39 make marks at predetermined left and right positions on both sides of the glass plate G.

Then, the rotary arm 38 reverses and opens, and the marking machine 3
6 retreats to the standby position, the cylinder 47 moves the saucer 5
0 rises and the mark stamp 39 is replenished with marking agent for the next marking.

Once said reversal of the rotating arm 38 is completed, the cylinder 20 is actuated to return the marked glass plate G to the vertical position.

Next, the cylinder 13 raises the glass plate G to the height of the tongs, and the tongs hold the glass plate G at the marked position and carry it out.

Next, the rear glass stopper 16 is tilted by the cylinder 20, and the mounting table 12 is lowered to its original position.

This completes one marking operation, and the above operation is repeated thereafter.

The control device that performs the sequential operations of the above-mentioned operations can be easily assembled according to well-known circuits using ordinary relays, limit switches, etc., so a detailed explanation thereof will be omitted.

Since the present invention has the above configuration, it can produce the following remarkable effects.

(1) Since the glass plate is marked at the tongs gripping position in an upright position, it is possible to mark both sides at the same time, and as a result, the tongs are reliably prevented from slipping, which prevents them from falling during transportation and improves yield.

(2) When the glass plate is air-cooled and strengthened after the conveyance, both sides of the tongs gripping position receive the same thermal history, so there is no decrease in strength (poor polarization) at the gripping position, and the gripping Fractures due to location are reduced.

(3) Since the mark is a dot, the tongs hanging position is accurate, and marking agent does not adhere to areas other than the hanging point, so a post-process of wiping and cleaning is not necessary.

(4) Since the marking agent is replenished to the mark stamp each time, the mark will not be blurred.

(5) Since marking is performed with the glass plate in an inclined position, the glass plate is stabilized by its own weight and does not fall over during marking.

Furthermore, there is no risk that the mark striking device will come into contact with the tongs or the conveyance device.
