Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for drying clay roof tiles. [0002] It is known that clay roof tiles are manufactured from raw materials mainly composed of clay containing water. Therefore, since the tile body immediately after molding contains moisture, it is necessary to dry the undried tile body with a drying furnace. Therefore, a large number of undried tiles are placed horizontally on a drying pallet, the drying pallet on which the tiles are placed is sent to a drying furnace, and the drying pallet is heated by hot air from the drying furnace. It is widely practiced to dry tile tiles. However, conventionally, a drying pallet used for drying tile tiles is provided with a receiver for placing all tile tiles in one direction. The substrate was placed on a drying pallet with all tiles oriented in one direction. For example, a tile is placed on a drying pallet in a horizontal state with the head of the tile facing one side and the buttocks facing the other side, and alternately from one side of the drying pallet and the other side. Hot air is supplied to dry tiled materials. In this example, when hot air is supplied from one side of the drying pallet,
The head of the tiles located on the most side of the drying pallet is located on the most upstream side of the hot air supplied from one side, so it receives the hot air supplied from one side strongly, while being located on the other side. Since the bottom of the tile is located at the most downstream side of the hot air on one side, it receives weak hot air from one side. When hot air is supplied from the other side, the tail of the tile material located on the other side of the drying pallet is located on the most upstream side of the hot air supplied from the other side. The head of the tile located farthest to one side is weakest to the hot air from the other side because it is located at the most downstream side of the hot air at the other side. In this case, when the tile on the most side and the tile on the other side of the drying pallet are compared, the directions of the hot air received by both tiles are opposite to each other, and the direction of the hot air of both tiles is The receiving condition is different. In other words, in the conventional drying pallet, there is a problem that a difference occurs in a process of drying and shrinking of the tile substrate depending on a position of the pallet on which the tile substrate is placed, and the form of the tile substrate after drying varies. . Therefore, in order to solve the above-mentioned problem, for example, a tile-drying apparatus employing a shelf board disclosed in Japanese Patent Application Laid-Open No. 8-231263 is known. This drying device is to dry tiled material placed on a truck by supplying hot air from both outer sides to the inside of a truck traveling in a drying oven in two rows. And the other side of the trolleys are placed with the tiles facing in opposite directions (symmetric). According to this drying apparatus, it is supposed that the above-mentioned problem is solved. However, the drying apparatus includes a receiver in which the orientations of the tiles of all the drying pallets stacked on the cart are oriented in one direction. there were. Therefore, in addition to the space required for the carriage to travel in two rows in the drying furnace, the drying pallet (shelf) or the carriage needs to be turned 180 ° in the horizontal direction. It was inevitable that ancillary facilities for inverting in the horizontal direction would be large. [0007] The problem to be solved by the present invention is that, in the conventional drying pallets, in order to eliminate variations in the form of the tiles, the drying pallets are not provided in a drying furnace. If the tiles are arranged in opposite directions to correspond to the hot air supplied alternately in the horizontal direction in the drying furnace, it is necessary to invert the drying pallet by 180 ° in the horizontal direction. It is unavoidable that ancillary equipment for reversing the horizontal direction inevitably becomes large-scale, and is limited to a drying oven in which two rows of carts can travel. An object of the present invention is to reduce the size of a tile placed on a drying pallet, which may cause a difference in the state of receiving hot air depending on the position where the tile is placed on the drying pallet. An object of the present invention is to provide a pallet for drying tiled tiles without requiring additional equipment. In order to achieve the above object, a pallet for drying a shingle according to the first aspect of the present invention has a terrain provided with a receiving member that follows the upper surface of the shingle. A pallet for drying, wherein an area on the upper surface of the pallet for drying is divided into an area on one side and an area on the other side, and a receiver for one side is provided in the area on one side, and another area is provided in the area on the other side. Side receiving members are provided, and the tiles placed on the one side region and the other side region are arranged so that the directions thereof are opposite to each other. According to the first aspect of the present invention, the area on the upper surface of the drying pallet is divided into an area on one side and an area on the other side,
The one-side area is provided with the one-side receiver, and the other-side area is provided with the other-side receiver, and the tile pallet placed on the one-side area and the other-side area of the drying pallet is provided. Since the directions are opposite to each other, simply send the drying pallet to the drying furnace and arrange tile tiles in the drying furnace in opposite directions in the drying furnace in response to the hot air supplied alternately and horizontally in the drying furnace. Can be done. The invention according to claim 1 is as described above, and has the following effects. By simply feeding the drying pallet into the drying furnace, the tiles on one side and the other side are arranged in the drying furnace in opposite directions to each other in accordance with the hot air alternately supplied in the horizontal direction in the drying furnace. This makes it possible to prevent the tiles placed on the drying pallet from causing a difference in the state of receiving hot air depending on the position where the tiles are placed on the drying pallet. There is no need to turn the cart 180 ° in the horizontal direction, and no additional equipment for turning the pallets for drying in the horizontal direction is required. Further, since the number of carts that can travel in the drying furnace is not limited, even in a drying furnace in which only one row of carts can travel, the tiles placed on the drying pallet can be tiled on the drying pallet. It has become possible to suppress the point where the state of receiving hot air varies depending on the position where the substrate is placed. Therefore, space saving can be realized as well as cost reduction of the entire drying equipment.

, Six sets of one-side receiving members 18 are fixed. Therefore, when the pair of support members 14 and 14 and the six sets of other-side receiving members 18 are regarded as one row, three rows and 18 tile substrates W are provided on the other side in the area on the other side of the drying pallet 10. It will be placed with its head turned. Next, a method of using the drying pallet 10 according to this embodiment will be described. First, a tile W W is placed on one side of the receiving pallet 16 of the drying pallet 10 and the other side of the receiving pallet 18.
Is placed. At this time, the tiles W in the area on one side from the center of the drying pallet have the head of the tiles W directed to one side, while the tiles W in the other area are the heads of the tiles W Is supported facing the other side. When the tile W is placed on the drying pallet 10, the drying pallet 10 is placed on the drying pallet 1.
Zeros are sequentially loaded on a truck 30 for loading. In this embodiment, the drying pallet 1 is mounted on one carriage 30.
Pallets 1 for drying.
The cart 30 in which the loading of 0 is completed is sent to the drying furnace 20. In addition, the code | symbol "Q" of FIG. 2 represents the boundary of the tile W on one side and the tile W on the other side for convenience of explanation. The drying furnace 10 of this embodiment is a tunnel-type drying furnace 10 in which a truck track 22 is provided.
Are laid, and the trucks 30 can run on the truck track 22 in a line. Further, blowing fans 24 and 26 for supplying hot air to the carriage 30 in the drying furnace 10 from both sides are provided. Blow fan 2
4 is provided near the side wall on one side of the drying furnace 20, and the blower fan 26 is provided near the side wall on the other side, and both of the blower fans 24, 26 travel through the track 28 for the fan. Can travel back and forth in the furnace in parallel with.
Further, a plurality of these blowing fans 24 and 26 are provided at predetermined intervals in the longitudinal direction of the drying furnace 10. Therefore, the tile substrate W sent into the drying furnace 10 is dried while the bogie 30 passes through the drying furnace 10, and the tile substrate W is dried while the tile substrate W is dried. Hot air is intermittently supplied from one side to the drying pallet 10 loaded on the cart 30 by the blower fan 24. On the other hand, since the hot air is also intermittently supplied from the other side from the blower fan 26, the tile fabric W in the drying pallet 10
The hot air is supplied alternately from one side and the other side,
Drying of the tile body W is promoted. The pallet 10 for drying is blown by the blower fan 24.
When the hot air is supplied from one side, the head of the tile fabric W located at the one side of the drying pallet 10 is located at the most upstream side of the hot air supplied from the one side. Receive strong hot air. On the other hand, since the head of the tile body W located on the other side is located on the most downstream side of the hot air on one side, it receives weak hot air from one side. Further, when hot air is supplied from the other side of the drying pallet 10 by the blower fan 26, the head of the tile substrate W located at the other side of the drying pallet 10 at the head of the hot air supplied from the other side becomes the most. Because it is located on the upstream side, it strongly receives the hot air supplied from the other side, while the head of the tile fabric W located on the most one side is located on the most downstream side of the hot air on the other side, so You will receive hot air weakly. Looking at the state of the hot air received by the tile substrate W, when the hot air is supplied alternately and equally from one side of the drying pallet 10 and the other side, the area is located on one side from the center of the drying pallet 10. Comparing the placed tile substrate W and the tile substrate W from the center of the drying pallet 10 to the region on the other side, it can be understood that the state of receiving the hot air becomes equal.
In other words, the tiles W are placed symmetrically in the area on one side and the other side from the center of the drying pallet 10, and the hot air supplied from one side and the other side of the drying pallet 10 This is because of the same conditions. As described above, the tiles W are placed symmetrically on the one side and the other side from the center of the drying pallet 10, so that the tiles W are placed on the drying pallet 10. It is possible to suppress the difference due to the state of the hot air depending on the position. Therefore, the difference in the drying shrinkage of the tiles W is suppressed, and the variation in the form of the dried tiles W is reduced. In addition, by using the drying pallet 10 according to this embodiment, a large-scale pallet reversing device and ancillary equipment are not required, so that the equipment can be significantly reduced and space can be saved. It can also be used in a drying oven that can only pass through it, and there is no restriction on the implementation depending on the type and structure of the drying oven. Next, a drying pallet 40 according to another embodiment will be described. This drying pallet 40 is for drying the tile base Wf of the F-shaped tile,
This is provided with a substantially rectangular frame 42 as in the previous embodiment. The one-side receiving member 44 is provided in a region on one side from the center of the drying pallet 40, and the other-side receiving member 46 is provided in a region on the other side from the center of the drying pallet 40. The one-side receiving member 44 and the other-side receiving member 46 of this embodiment are in the shape of a square bar, are laid horizontally on the frame 42, and have one-side receiving member 44 and the other-side receiving member. 46 are fixed to the frame 42 so as to be parallel to each other. In the case of the tile body Wf of the F-shaped tile, in order to support the substantially horizontal back surface thereof, for example, a square bar having a rectangular cross section having a horizontal plane is used for the one-side receiving member 16 and the other-side receiving member 18. The receiving members 44 and 46 can be adopted as they are without forming a special shape. In this embodiment, the one-side receiving member 44 is used.
The head of the tile body Wf placed on the other side faces the one side, and the head of the tile ground Wf placed on the other side receiver 46 faces the other side. The receiving tools 46 are provided respectively. The one-side receiving member 44 and the other-side receiving member 46 are each a set of three, and support the tiled fabric Wf. It supports six tiles Wf each time. Therefore, since there are three rows in each of the areas on one side and the other side, the drying pallet 40
Can place 30 tiles Wf. The receiving surfaces of the one-side receiving member 44 and the other-side receiving member 46 follow the shape of the back surface of the tiled fabric Wf. However, since the back surface of the tiled fabric Wf of the present embodiment is flat, the receiving surfaces correspond to each other. It is formed in a flat shape. Drying pallet 40 according to this embodiment
Since the method of using is basically the same as that of the drying pallet 10 according to the above embodiment, the description of the above embodiment is referred to (see the description of paragraphs “0019” to “0026”). Also, in these embodiments, the head of the tile in one area is directed to one side, and the tile in the other area is directed to the other side. However, it goes without saying that the present invention can be applied not only to the head and tail direction of the tiled fabric but also to the cross collar direction. Furthermore, in these embodiments, the areas on one side and the other side of the drying pallet are set to be equal.
The area on one side and the area on the other side may be set to have different area ratios according to the supply state of hot air from the drying furnace. Further, the one-side receiving member and the other-side receiving member on which the tile substrate is placed may be detachable from the supporting member or the frame, or the supporting member to which each receiving member is fixed may be detachably attached to the frame. It may be free. The orientation of the tile can be changed by making each of the receiving members or the supporting members detachable, and mounting each of the receiving members or the supporting members on the drying pallet in the opposite direction. This makes it easy to set the area on one side and the area on the other side to different area ratios according to the supply state of the hot air from the drying furnace as described above, and, if necessary, to use the conventional drying pallet. It is also possible to place all tiles in the same direction. Also,
The inventor also plans to stack and fix the drying pallets according to these embodiments on a trolley, and to integrate the pallets with the pallet for drying.
