Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ceramic product pallet that can be placed on any form of ceramic product used in a baking furnace or a drying furnace.

[0002]

[Prior art]

 Conventionally, in a pallet where ceramic products such as roof tiles are placed and used in a baking furnace or a drying oven, the mounting portion should correspond to the form of the ceramic product so that the form of the ceramic product is not damaged. However, every time the shape of the ceramic product changed, many pallets corresponding to this had to be used.

Therefore, the pallet is wasted and the cost required for the production is wasted, and each time the form of the ceramic product changes, the pallet must be replaced with a corresponding one, which lowers the work efficiency. Was invited.

[0004]

[Problems to be solved by the device]

 The present invention configures a pallet used in a baking furnace or a drying furnace so that it can be applied to all types of ceramic products. The purpose is to provide a ceramic product pallet that eliminates waste, improves work efficiency, and lowers the cost of ceramic products.

[0005]

[Means for Solving the Problems]

 According to the present invention, the pallet used for placing and using the ceramic products such as roof tiles in the firing furnace or the drying furnace based on the above-mentioned conventional technology uses the pallet corresponding to each time the form of the ceramic product changes. In view of the issues that must be addressed, we will support the ceramic product form while supporting the ceramic product by minimizing the contact area with the ceramic product in order to eliminate deformation factors due to its own weight.

From this point of view, the base frame is provided with an appropriate number of support holes, and support pins having protruding heights are set in the respective support holes so that the support pins can be freely inserted and removed, thereby supporting the form of ceramic products. In order to do this, select a support pin with a protruding height as appropriate and insert it into the support hole to support the appropriate location of the ceramic product on the support pin so that the ceramic product is stably placed on the base frame. At the same time, the contact point with the ceramic product is minimized so that the deformation factor due to the self-weight of the ceramic product can be eliminated and supported, and the above drawbacks are not solved.

Further, by providing a through hole in the base frame, the bottom portion of the base frame is blown through, and the ceramic products are supported by the support pins while floating above the base frame. Therefore, the entire surface of the ceramic product can be uniformly baked or dried.

Furthermore, since the support pin that is in contact with the ceramic product is made of a heat-resistant metal, even if the glaze flows down to the support pin during firing, the support pin does not expand the glaze. Since the coefficient is different, the supporting pins do not adhere to the ceramic products, and the ceramic products can be easily removed from the pallet after firing.

[0009]

[Action]

 According to the present invention, in order to stably mount the ceramic product on the base frame, a support pin having a protruding height is appropriately selected and inserted into the support hole so as to correspond to the form of the ceramic product. , Support the appropriate places of the ceramic products on the support pins, and place the ceramic products on the pallet.

Since the ceramic products placed on the pallet in this manner are supported by the support pins in a state of slightly floating above the base frame, the entire surface of the ceramic products is evenly burned or evenly baked. Allows drying.

In addition, in the case where the base frame is provided with the through hole, the bottom portion of the base frame is opened through the through hole and is in a blow-through state, and the ceramic product is supported as described above. Since it is supported by pins floating on the base frame, the entire surface of the ceramic product can be evenly and uniformly baked or dried.

[0012] Furthermore, since the support pins that are in contact with the ceramic products are made of heat-resistant metal, when the ceramic products are picked up from the pallet, it is possible that the glaze may flow down to the support pins during firing. However, since the support pin has a different expansion coefficient from that of glaze, the supporting pin does not adhere to the ceramic product and the ceramic product can be easily removed from the pallet.
