Each piece is transferred and placed on a plate, carried into a baking kiln and baked.

As described above, as a method of stacking on a baking trolley before being carried into the baking kiln, for example, a method of manually transferring the raw green board after demolding to a shelf board is usually used. A large number of people lift or push it to transfer it from a wooden stand on which a raw base plate is placed to a shelf plate for firing.

In addition to this, as disclosed in Japanese Utility Model Publication No. 62-868, there is a method of adsorbing a green base plate by a vacuum suction action, lifting and moving it, and transferring it.

[0005]

However, in the method of manually transferring to a shelf board, the raw green board is large and not completely dried, so that it is apt to be bent, bent or damaged.
Further, it has a drawback that it is heavy and requires a large number of people, and the method of sucking up and transferring the green base plate by utilizing a vacuum suction action requires a large-scale vacuum suction device and The operation is complicated and the installation space is disadvantageous, and further, when packing the multi-tiered shelves, the work of sucking and releasing is repeated, resulting in poor work efficiency. Was there.

[0006]

According to the present invention, a multi-stage shelf board is provided on a baking carriage, and a green base plate is transferred and placed on the shelf board and loaded into a baking kiln. In the method, the level of the upper surface of the cushioning member and the sliding sheet laid on the shelf board and the lower surface of the raw green board are matched, the raw green board is slid to the shelf board side, and the cushioning member is slid on the shelf board. It is intended to provide a method for stuffing a large porcelain plate into a kiln, which is characterized in that the green base plate is transferred onto a shelf plate.

Further, in the present invention, the cushioning member has substantially the same length as that of the green base plate, one end of the cushioning member is placed on the front of the shelf, and the other end is hung from the front end of the shelf. In addition, the sliding sheet is laid on the upper surface of the shelf board covering the cushioning member placed on the front part of the shelf board and extending from the front part of the shelf plate to the rear part, and the tip part of the green ground plate is placed on this.

It also intends to provide a kiln packing method.

[0008]

According to the present invention, when the green base plate to be the ceramic plate is transferred onto the shelf plate provided on the firing carriage, the buffer member is made to have substantially the same length as the green base plate, and one of the buffer members is Place the tip part on the front part of the shelf plate and the other end part hanging from the front end of the shelf plate.Furthermore, the sliding sheet covers the cushioning member placed on the upper part of the shelf plate, Laying on the upper surface of the shelf board extending from the rear to the rear part, and on the rear part of the sliding sheet that overlaps with the front part of the cushioning member, first, while manually or mechanically sliding the front part of the green base plate placed on the dedicated pallet. Place it,
When the raw green base plate is pushed toward the shelf plate as it is, both the cushioning member and the sliding sheet slide to the edge of the shelf plate while the front part of the raw green plate is partially placed, and the sliding sheet moves to the shelf. With the cushion member interposed between the raw green board and the shelf board, the raw green board is entirely transferred onto the shelf board.

In this state, the rear end of the sliding sheet and the cushioning member are interposed between the shelf plate and the lower portion of the front part of the green base plate. Pull out from between the main plate and the cushioning member.

In this way, the raw green board can be transferred to each shelf board one after another while adjusting the level of the dedicated pallet to the surface of each shelf board.

Then, a firing trolley in which the green substrate is transferred to each shelf is carried into a firing kiln to fire a large ceramic plate.

[0012]

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

FIG. 1 shows a firing carriage A which is carried into a firing kiln and a dedicated pallet C which is lifted by a lifter B.

The firing carriage A supports a wheel 1 arranged on a passage leading to a firing kiln (not shown), a shelf D provided on the wheel 1 in a multi-stage overlapping manner, and a shelf D. It is composed of a pillar 2 for doing.

The shelf plate D is constructed by fitting a plate made of a refractory furnace material into a refractory brick pillar 2.

The lifter B has a fork 3 which can be raised and lowered, and the fork 3 lifts a dedicated pallet C to raise and lower the pallet.

The dedicated pallet C is a dedicated wooden stand on which the green base plate X is placed, and has leg pieces 4 on its lower surface to form a space for inserting the fork 3.

On the special pallet C, a green base plate X is placed.

Here, a method of manufacturing the green base plate X will be described.

The green base plate X is formed by pouring sludge into a plate-shaped mold to solidify it, and removing the mold from the wooden mounting plate.

A cloth is laid in advance on the wooden placing plate to prevent the green substrate X to be removed from the wooden substrate from shrinking and being damaged during drying.

The raw green board placed on the wooden board is further transferred to the dedicated pallet C and dried at room temperature here.

A cushion material such as polyethylene foam (trade name: mirror mat) is laid on the upper surface of the dedicated pallet C.

The green base plate X transferred onto the dedicated pallet C is surface-finished with sandpaper or the like.

As described above, the dried green base plate is placed on the dedicated pallet C.

Next, the work of transferring the green base plate X from the dedicated pallet C to the shelf plate D of the baking carriage A will be described with reference to FIGS.

First, before transferring the green base plate X, the front end portion of the cushion member S as a cushioning member having substantially the same length as the ceramic plate is placed on the front portion of the shelf plate D in advance. The rear part is hung from the front end, and the sliding sheet M is laid on the front and rear of the shelf D (see FIG. 3).

The cushion member S as a cushioning member is made of a sheet-shaped polyethylene member having a large number of convex portions in which air is enclosed, and the sliding sheet M is a Teflon sheet or the like whose surface easily slides.

The cushion member S is placed on the front end portion and the shelf plate D, and the rear portion thereof slightly hangs down from the transfer side edge of the shelf plate D and bends downward to form a hanging portion n. .

The cushion member S and the sliding sheet M may be laid over the entire width of the shelf D, or may be laid at required intervals.

Next, the lifter B is moved to raise the exclusive pallet C so that the surface of the exclusive pallet C and the surface of the sliding sheet M are brought to the same level (see FIG. 1).

Then, the green base plate X is slid manually or mechanically from the dedicated pallet C so that a part of the front end of the green base plate X is placed on the sliding seat M above the front end of the cushion member S. Move it so that it rests (see FIG. 4).

Since the sliding sheet M is a material whose surface easily slides, the green base plate X can be easily slid by hand.

In this state, the front part of the green base plate X is pressed against the rear part of the sliding seat M and the front end part of the cushion member S by the weight of the green base plate.

In this way, the tip of the green base plate X is placed on the rear part of the sliding sheet M of the shelf plate D,
In this state, the green base plate X is further pushed into the depth direction of the shelf plate D together with the sliding seat M and the cushion member S in the pressed state (see FIG. 5).

The green base plate X has a sliding sheet M only at the front end.
Since the cushion member S is pushed in while being placed on the shelf member, the cushion member S hanging from the front end edge of the shelf plate D is gradually pulled up and extended onto the shelf plate D, and at the same time, the sliding sheet M.
Is pushed out from the other side surface of the shelf plate D by pushing the green base plate X (see FIG. 5).

In this way, as shown in FIG. 6, when the green base plate X is entirely transferred onto the shelf plate D, the entire surface of the cushion member S is located between the raw base plate X and the shelf plate D. It remains held, and only the rear part of the sliding seat M is clamped by the green base plate X and the front part of the cushion member, and the front part of the seat M hangs down from the front end edge of the shelf plate D. (See Figure 6).

Then, by pulling the sliding sheet M, it is pulled out from between the cushion member S and the green base plate X,
The green base plate X is entirely transferred onto the shelf plate D via the cushion member S (see FIG. 7).

In this way, the green basin board X is sequentially transferred to each shelf board D while lowering the exclusive pallet C of the lifter one by one to match the level with the surface of the shelf board D.

After all the transfer to the shelf board D is completed, the baking carriage A is carried into the baking kiln and baked to make a large-sized ceramic plate.

A cushion member S as a cushioning member
Since the sliding sheet M on the upper surface of the sheet has a smooth surface,
When both are piled up, a gap in which air is stored is formed in multiple stages, and the gap supports the weight when the green base plate X is placed, prevents the cushion member S from being crushed, and the shelf plate. It has the function of smooth sliding on D.

Further, the sliding sheet M has a function of improving the sliding of the drawing because it is in a surface sliding state during the drawing work in the final step.

[0043]

According to the present invention, a cushion member as a cushioning member and a sliding sheet are laid on a shelf plate, and a green basin plate is slid and transferred from a dedicated pallet having a level adjusted on the cushion member. Therefore, it is possible to move while sliding the green base plate without requiring much manpower, and since the sliding seat and the cushion member are pressed by the weight of the green base plate, the cushion member and the sliding seat are pushed when the raw base plate is pushed. With that, slide movement can be done integrally,
There is no need for a large number of workers, so there is the effect that safe and simple transfer is possible with a simple work of lifting and pushing with a lifter.Furthermore, since the sliding sheet is a smooth surface, it can be used as a cushioning member in the lower layer. Since a gap is formed between these, this gap serves as an air storage space to support the weight of the green base plate, eliminate the crushing of the buffer member due to the weight of the green base plate, and Has an effect of making the sliding of the sliding sheet good, and furthermore, the sliding sheet can be easily pulled out in the final step.
