DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for loading a white background on a firing jig for supporting a white background on a firing cart while tilting the white background.

[0002]

2. Description of the Related Art Heretofore, the present applicant has filed Japanese Patent Application No. 7-185.
As No. 08, a pair of holding members for holding a plurality of white backgrounds or fired products at a time below a carriage which is reciprocally movable in the width direction of the firing carriage and which is inclinedly supported by a white background carrying line or a shelf board lowered from the firing carriage. An empty shelf board or a fired product is carried out by disposing a plate so as to be able to move up and down in a white background or the inclined direction of the fired product, and by transporting the flat roof tile sandwiched by the holding plate and lowering in the tilt direction of the fired product. We have developed a loading / unloading method and a loading / unloading device for a white background or fired product in a flat roof tile firing system that automatically loads a white background or fired product on the line.

[0003]

However, in the above-mentioned loading / unloading apparatus, since a white background or a baked product is pinched, it is fixed between the holding plates, and the firing jig and the white background are distorted. Due to this, all the white backgrounds do not contact the firing jig at the same time, and the gap between the holding plates is expanded while a part of the white background is in the separated state, or the holding plate descends until the separated white background contacts the firing jig In other words, since the sandwiching plate is slid with respect to the already stopped white background, there is a risk that at least one of the firing jig and the white background may be damaged when the white background collides with the firing jig. There were issues that had to be solved.

[0004]

SUMMARY OF THE INVENTION According to the present invention, there is provided a mounting method for supporting a white background on an upper surface of a substrate in consideration of the problem that at least one of a firing jig and a white background is damaged. A horizontal moving unit capable of reciprocatingly moving between a conveying line of a firing jig in which the plates are arranged in series and an upright conveyor on a white background, a vertical moving unit provided in front of the horizontal moving unit, and a vertical moving unit. In the lower part, a white background supporting / transporting section is provided so as to be movable horizontally in a direction perpendicular to the horizontal moving section. A plurality of back support members are arranged in the upper portion in the width direction of the side plate, and both lower end portions of the lower end side of the white background are supported by the lower support portions, and the upper side of the white background. Lean on the backing member, and carry the white background in an inclined posture. By, in the manner simultaneously or successively white background will be transferred to the firing jig in the middle oblique descent of the side plates, to solve the above problems.

It is almost the same as.

Next, a method of loading the white background W into the firing jig 30 and the operation of the white background loading apparatus 1 will be described in detail. (1) The white background W conveyed in a flat state is raised by the upright conveyor 2 in an inclined manner, and when a predetermined number of white backgrounds W are lined up on the upright conveyor 2 in an inclined state, the white background W is waiting on both sides of the upright conveyor 2. The space between the side plates 13 and 13a of the white background loading device 1 narrows and rises slightly upward, so that the lower supporting member 2
, 21a, 21a, etc., both sides of the lower end of the lower side of the white background W are supported downward, and the upper side of the white background W is leaned on the back members 22, 22,..., 22a, 22a,. (FIG. 5
(See (a) and (b)). (2) The white background W is lifted by raising the side plates 13 and 13a obliquely upward by the advance of the white background supporting and transporting unit 6 and the elevation of the vertical moving unit 5 (see FIG. 5C). (3) The firing jig transport line 3 is moved by the reciprocation of the horizontal moving unit 4.
It moves to the upper part of the upper empty baking jig 30 and retreats obliquely downward by the retreat of the white background supporting and transporting unit 6 and the lowering of the vertical moving unit 5 to insert the white background W between the mounting plates 32, 32a,. 6
(See (a) and (b)). (4) After that, the white background W is slightly lowered by the lowering of the vertical moving unit 5 so that each white background W is brought into contact with the upper surface of the firing jig 30.
All the white backgrounds W are transferred to the firing jig 30 by leaning on the mounting plates 32, 32a,... (See FIG. 6C). (5) After the transfer, the space between the side plates 13 and 13a is expanded, and at the same time, is raised upward, moved to the position above the upright conveyor 2 by the forward movement of the horizontal moving unit 4, and then lowered by the vertical moving unit 5 to move the side plates 13 and 13a. Is lowered, and the side plates 13 and 13a are made to stand by the side of the upright conveyor 2 (see FIG. 5A).

In summary, the present invention provides a white background W
Are vertically movable between a conveying line 3 of a baking jig 30 in which mounting plates 32, 32a... Are arranged in an inclined manner and above a standing conveyor 2 on a white background W; 4
, And a white background supporting / transporting unit 6 disposed below the vertical moving unit 5 so as to be horizontally movable in a direction orthogonal to the horizontal moving unit 4, so that the white background W stands upright. It can be transferred from the conveyor 2 to the firing jig 30 on the transport line 3 while being inclined. Also, the white background supporting and conveying section 6
, A plurality of lower support members 21, 21..., 21a,
.., And a plurality of back members 22, 22,.
22a are arranged in the width direction of the side plates 13 and 13a.
Are merely placed on the lower support members 21, 21,..., 21a, 21a, so that even if the white background W abuts on the firing jig 30, the side plates 13, 13a descend as they are. Unnecessary external force does not act on the jig 30 and the white background W and the firing jig 30
Can be prevented from being damaged, and the practical effect thereof is extremely large.
