Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a device that stops two mounting plates in a predetermined position on a conveyor while positioning them. This mounting plate is formed of a heat-resistant material in a plate shape, receives a plurality of aligned tile base groups, and passes through the firing furnace together with the tile base groups.

[Prior art]

Conventionally, the firing preparation process of the tile base has been performed as follows. First, while aligning a plurality of tile substrates obtained by the molding device in a plurality of rows on an aligning conveyor, an empty mounting plate from which the firing tiles have been removed after the previous firing step is removed using a conveyor. Carry in the tile base transfer position in a row. Subsequently, the group of tile substrates arranged on the aligning conveyor is transferred onto the two mounting plates stopped in parallel at the tile substrate transfer position by using the suction transfer tool. Finally, the two mounting plates receiving the tile base group are carried out to the firing step.

[Problems to be solved by the device]

By the way, the above-mentioned mounting plate expands due to thermal influence after the firing process, and the planar dimension becomes large. For example, if a 650 mm square mounting plate is repeatedly used for one month by firing once for 2 hours, one side will extend by about 1 to 2 cm. With this expansion, the stop position on the conveyor is slightly displaced from the predetermined tile base transfer position due to the expansion, and the tile base group is not transferred to the predetermined receiving area. Therefore, the tile base material located on the side edge of the tile base material group may be eroded from the mounting board and fall off from the mounting board during transportation, and may not be fired.
In particular, when the tile base material is a small piece (for example, less than 100 mm square), this dropout frequently occurs, resulting in a decrease in yield. In order to solve the above problems, an object of the present invention is to provide a positioning device for a tile base group placing plate that can position and stop two placing plates in parallel at a predetermined position on a conveyor. To do.

[Means for Solving the Problems]

The gist of a positioning device for a placing plate for tile base group according to the present invention (hereinafter referred to as “main device”) is to extend a conveying path of the placing plate for tile base group in a left-right parallel manner and along a front-back direction. Conveyor, parallel width expanding device installed side by side in the widening area on the conveyor loading side, and positioning device installed side by side in the positioning area on the unloading side of the conveyor. Left and right side-by-side lifting devices that move up and down from a standby position below the loading surface to a mounting plate lifting position above the transport surface height, and a separation / contact operation tool that moves the rising left and right lifting devices in directions away from each other. The positioning device is equipped with a stopper that advances and retreats from the standby position to the exit position of the positioning area, a reference position determining tool that is fixed at an intermediate position between the left and right of the positioning area, and the outer side of the positioning area. It is provided with a mounting plate side pressing tool to advance and retreat toward the.
