Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar tanning apparatus used for producing irregularly shaped glass products, such as oval or oblong glass dishes and containers.

To manufacture an oval glass plate, molten glass is press-molded into an oval shape, and then the periphery of the opening is burned with a burner to make the periphery of the opening round and round with no corners.

The simplest method for tanning as described above is to arrange burners in an oval shape around an oval glass plate, with each burner heating the periphery of the mouth. Not only is this method unsuitable for mass production because it heats parts one by one, but it also has the problem of not being able to uniformly finish the entire mouth periphery because each burner flame heats a certain position on the mouth periphery.

In addition, if the glass plate is perfectly circular, by rotating the glass plate while moving and heating the rim of the mouth with a burner placed midway through the movement, the distance between the periphery of the mouth and the burner can be kept constant. Moreover, since the entire periphery of the opening is continuously heated by the rotation of the glass plate, the periphery of the opening can be uniformly finished, and at the same time, mass production through automation becomes possible.

However, in the case of an elliptical glass plate, when solar tanning is performed using the method described above, due to the rotation of the glass plate, the distance between the mouth periphery and the burner becomes closer in the long axis direction of the ellipse. As a result, the spacing in the direction of the short axis becomes too large, resulting in insufficient firing, making it impossible to finish the periphery of the mouth uniformly.
At present, it is impractical to do so, and as demand for oval glass plates increases, there is a strong desire to automate the solar tanning process.

This invention has been made in view of the above-mentioned points, and provides a tanning device that can completely automatically tan glass products of irregular shapes such as oval shapes, efficiently and uniformly. The purpose is to

The structure of the present invention is to give movement and rotation to a glass product of different diameters, to arrange the glass product so that it can move forward and backward with respect to the glass product passing through a large number of burners in the direction of movement of the glass product, and to arrange each burner to have the same shape as the glass product. The burner is moved forward and backward by a cam that rotates integrally with the burner, and the distance between the periphery of the mouth of the glass product passing through and each burner is kept constant to perform tanning.

Hereinafter, the present invention will be explained based on embodiments shown in the accompanying drawings.

As shown in the figure, the running body 1 is formed into an endless oval shape.
A supply mechanism 2 for an oval glass plate A is provided at one end of the elliptical glass plate A, a heating mechanism 3 for solar tanning is disposed in the middle of one straight traveling portion of the traveling body 1, and a heating mechanism 3 for solar tanning is provided at the other end of the same. A take-out mechanism 4 for taking out the rear glass plate A is provided.

The traveling body 1 has two sprockets 7 and 8 attached to each end of a frame 6 provided on a movable trolley 5, each having two upper and lower stages.
Endless chains 9 are wound around the upper and lower sprockets at both ends, and the chaino 9 is moved in the direction of arrow B in FIG. 2 by a motor 10 that drives the sprocket 8 at one end.

A holder 11 is placed at a constant interval around the outer circumference of the chino 9.
Each holder 11 holds a vertical rotating shaft 12 so as to be movable in a straight line.

As shown in FIG. 3, the holder 11 has wheels 13 on both sides thereof, and an inner guide rail 14 and an outer guide rail 15 arranged on the frame 6 so as to sandwich the chino 9.
The wheels 13 are placed on the wheels 13, and each holder 11 is mounted together with the chino 9.
is designed to move smoothly.

A pinion 16 is attached to the lower end of each rotating shaft 12, and a support base 18 on which the glass plate A is placed is fixed to the upper end via an intermediate pedestal 1T.

Although the details of the support stand 18 are omitted, the upper surface is formed into four steps, and the lower part of the intermediate holder 11 is removably fitted into this recessed part, and the lower end grounding part of the glass plate A is just placed on the upper surface of the support stand 18. It is provided with a recessed hole to fit into, so that the glass plate A can be supported to rotate together with the rotating shaft 12.

Therefore, as many intermediate pedestals 17 as the types of glass plates A are prepared,
If you select and use this, you can respond to changes in glass dishes.

A cam 19 having the same planar shape as the glass plate A is fixed in the middle of the rotating shaft 12.

This cam 19 is arranged so that its long axis and short axis are in the same direction as the glass plate A placed on the support stand 18.

Various types of cams 19 are available that match the planar shape of the glass plate A, and the one that corresponds to the glass plate to be processed is attached to the rotating shaft 12.

The heating mechanism 3 includes a large number of burners 2 at approximately the same height as the glass pan A in the portion where the chino 9 moves linearly.
1 are arranged at regular intervals in the direction of movement, and are moved forward and backward by a cam 19 of a glass plate passing through each burner 21.

Each burner 21 is arranged perpendicularly to the moving direction of the chino 9 so that a nozzle 22 at the tip can move forward and backward relative to the periphery of the opening of the glass plate A.

As shown in FIG. 3, directly below each burner 21, a reciprocating rod 25 is connected to the burner 21 by being supported by rollers 24 attached to a support frame 23 on the movable cart 5 at the same height as the cam 29. The rollers 2 are arranged parallel to each other and are mounted on the support frame 23.
The rear end of the burner 21, which is partially supported at 6, is connected to the advance/retreat rod 25 by a link 27, and the rear end of the advance/retreat rod 25 is connected to the lower end of the sliding arm 28, whose upper end is pivotally fixed to the support frame 23, and the elongated hole. A spring 29 stretched between the sliding arm 28 and the support frame 23 imparts forward elasticity to the advancing/retracting rod 25 in the direction in which the trochanter 30 at the tip is always in pressure contact with the cam 19.

The advancing/retracting rod 25 and the burner 21 are linked so as to move forward and backward in unison, and when the advancing/retracting rod 25 advances or retreats due to the rotation of the cam 19, the burner 21 moves equally with respect to the rotating glass plate A.

Note that the burner 21 has a trochanter 30 of the advancing/retracting rod 25 connected to the cam 19.
The nozzle 22 is set so as to maintain a predetermined distance between the nozzle 22 and the periphery of the opening of the glass plate A when the nozzle 22 comes into contact with the glass plate A.

A rack 31 with which the moving pinion 16 meshes is disposed below the burner parallel portion of the heating mechanism 3. When the glass plate A passes through the heating mechanism 3, the rack 31 and the pinion 16 mesh with each other, so that the rack 31 is engaged with the moving pinion 16. It is designed to rotate.

When the cam 19 attached to the rotating shaft 12 passes through the heating mechanism 3, it sequentially presses each advancing/retracting rod 25 and simultaneously moves while rotating. The burner 21 passes through the glass plate A
The robot must move forward and backward while maintaining a constant distance between it and the periphery of the mouth.

Further, FIG. 4 shows another advancing/retracting mechanism for the burner 21 in which advance/retreat is given by the cam 19, and the tip of the burner 21 is moved forward/backward by the cam 19.
The pipe 4 has an advancing/retracting rod 25 fixed to a support frame 23.
1 and a bush 42, the rear end of the advancing/retracting lever 25 is connected to the sliding arm 28, the lower end is connected in the middle of the advancing/retracting lever 25, and the upper end of the vertical lever 43 is attached to the support frame 23. It is held by a guide 44, and a vertical rod 43 moves horizontally.

The burner 2 is inserted through the angle adjustment mechanism 45 in the middle of the vertical rod 43.
1 is fixed, a nozzle 22 faces the periphery of the opening of the glass plate A, and a spring 29 is connected to the lower end of the sliding rod 28.

If such a structure is adopted, the height position of the nozzle 22 can be adjusted freely, and the burner 21 will move horizontally while remaining in an inclined state, so that the height position of the nozzle 22 with respect to the glass plate A can be adjusted. There is no change, and the entire periphery of the mouth can be heated uniformly.

The mouth-baking device of the present invention has the above-mentioned configuration, and the supply mechanism 2 sends the glass plate A press-molded on the turntable 32 onto the intermediate conveyor 34 using the vacuum type take-out machine 33; The glass plate A that has been placed is fed by the take-out machine 35 onto the intermediate pedestal 17 of the support 18 located at the left end in FIG. 2 of the traveling body 1.

The traveling body 1 moves in the direction of the arrow B in FIG. Align the arrangement of 19.

As shown in FIG. 2, this guide 36 is formed of a sliding plate that slides on each of the glass pan A and the cam 19, and for example, the guide 36 is configured so that the long axes of the glass pan A and the cam 19 are both along the moving direction. It is.

When the glass plate A faces the tip of the heating mechanism 3, the pinion 16 first engages with the rack 31, so that it moves forward while rotating, and then the cam 19 comes into contact with the advancing/retracting rod 25 while rotating.

Each burner 21 is activated by the flame from the nozzle 22 at the tip.
The periphery of the opening of the passing glass plate A is heated, but by the rotation and movement of the cam 19, the burner 21 facing the glass plate A moves back and forth so as to maintain a constant distance between it and the periphery of the opening. work

Therefore, as shown in FIG. 2, the rotating and moving glass plate A is heated continuously by each burner 21 under equal conditions at its mouth periphery, so that the mouth is baked to a predetermined degree.

The glass plate A that has passed through the heating mechanism 3 stops rotating because the pinion 16 is released from the rack 31, and the glass plate A passes through the guide 37.
When it passes through, its attitude is controlled again and it advances to the take-out mechanism 4, where it is taken out onto the cooling conveyor 38.

In this way, the support stands 1 are attached to the traveling body 1 at regular intervals.
Each time 8 faces the supply mechanism 2, the glass plate A is supplied, and while the glass plate A is moved, the heating mechanism 3 rotates it, and the cam 19 and the advancing/retracting rod 25 give each burner 21 movement. The distance between the burner 21 and the periphery of the mouth of the glass dish is kept constant, and the periphery of the mouth is continuously heated under equal conditions.

As described above, according to the present invention, since the structure is as described above, the periphery of the mouth of the irregularly shaped glass product can be heated continuously under exactly the same conditions, and the mouth-burning of the irregularly shaped glass product can be automatically performed. become.

Furthermore, since the irregularly shaped glass products can be baked without being moved, mass production of irregularly shaped glass products is possible, and manufacturing costs can be significantly reduced.
