Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for lowering a group of ceramic bodies stacked in stacks from a cart after being conveyed through each ceramic furnace for drying, bisque firing, 9-fired, etc. This invention relates to a counter-transfer loading device that lifts up the group of ceramic blanks, changes their posture, and transfers them to a conveyance means for the next process.

In the case of drying or firing in a production line for ceramics (for example, tiles), multiple ceramic bodies are stacked on a cart in a stacked manner, and the stacked cart is conveyed through each ceramic furnace. There are cases where it is done. Conventionally, in the above-mentioned cases, it has been considered impossible to operate a ceramic manufacturing line continuously from beginning to end in an automatic conveyance manner. This is because the ceramic bodies removed from each ceramic furnace must be unloaded from the trolley by hand in order to proceed to the next process (for example, glazing, etc., where they are distributed and transported separately). Traditionally, in such cases, the ceramic bodies were generally packed in large boxes. This is because each process in the firing process is overproduced in order to distribute the ceramic bodies arranged on a conveyor belt such as a belt conveyor without being interrupted during processes after glazing (for example, during firing, etc.). This is for the purpose of stocking large boxes and increasing the efficiency of moving ceramic bodies71). However, the intervention of this large box had the following drawbacks: 1) The work of filling the large box and the work of taking it out from the large box and arranging it on the glazing conveyor was done manually, so it was very time consuming. It's hard work 0
2) A wide range of floor space is required for preparing and stocking large boxes. 3) VJ for transporting large boxes is carried out by a forklift.
The floor space required for transportation routes is quite large, and ceramic bodies are often damaged during transportation by forklifts.

5) To ensure uninterrupted drying and firing, a stock of ceramic bodies must be kept at all times, and the molding equipment must be in excess of the ceramic conveyance capacity (for example, a dry pressure press stand). Must keep 062'
! ! :Friend, with the stock shown in 5) above, it is difficult to obtain ceramics of consistent quality because the residence time (curing time) of each ceramic body is different from molding to feeding into the drying oven. 6 fc.

Furthermore, each of the above-mentioned drawbacks has become a factor that requires at least two or more buildings to separate each process up to firing in the production line for ceramic bodies. This was done in view of the above-mentioned circumstances, and the group of ceramic bodies stacked in stacks is lifted onto the cart carried out from each ceramic furnace, and placed on the conveyance means that continues to the next process. The purpose of this project is to provide a counter-transfer loading device that changes the posture and transfers the item, thereby fully automating the transfer from the trolley, thereby making it possible to thoroughly save labor and manpower in ceramic manufacturing factories. The present invention will be described below based on one embodiment thereof.

This device as described above is installed in the ceramic production line.
It is installed in the delivery area between the conveyance paths provided in front and behind each other. For example, this is the boundary area between the running rail of the trolley installed through the dry wire furnace or bisque furnace, and the transfer conveyor connected to the next process. A cross-sectional view is shown and its movement will be explained below. In the figure, 35 is a rail, 34 is a trolley, and 36 is a roller conveyor that is directly connected to the rail 35.

After the cart 34 on which the ceramic bodies 37 are stacked in a stacked manner is taken out of the valley furnace (not shown), it is guided by a rail 35 and placed directly on the UJ of this device. In order to hold the ceramic body group 37' in the front row on the advancing direction side, the advancing/retracting frame 3 moves forward within the rotating frame 2 and the chuck mechanism 2

Next, the advancing/retreating frame 3 retreats to the back of the rotating frame 2, and the base frame 1 rises. After the base frame 1 is fixed upward (indicated by a dotted line), the rotating frame 2 moves forward of the base frame 1. Flip to . After the reversal, the holding mechanism 6 holds the ceramic element by allowing the holding frame 4 to slide on the front curve of the advancing/retracting frame 3 (on the downward side in the dotted line drawing) and moving the advancing/retracting frame 3 forward again (downward in the dotted line drawing). The body group 37' is transferred to the conveyor belt of the roller conveyor 36. Next, by releasing the chuck mechanism 22 and the pressing mechanism 23, the ceramic body group 37' is transferred to the roller conveyor 36.
It is transported to the next process. Trolley 34Ir! Each time the laminated group is transferred onto the roller conveyor 36, it is fed at a pitch of '1i-1 by the side length of the ceramic body 37, and waits for the next transfer operation.

In addition, in the Fufu example, the transfer position of the ceramic body group 37 was moved to a roller conveyor 36 installed above the stacked cart.
As mentioned above, a device equipped with an elevating mechanism such as the rail member 13 is shown, but for example, a roller conveyor 36 or , When the ceramic body group 37 is to be counter-transferred onto another conveying means in a parallel manner, the heavy equipment W may be placed on a turntable. In this way, the detailed configuration and structure of this device can be changed as appropriate depending on the mode of implementation. Furthermore, the number of stacked rows of ceramic bodies to be held can be arbitrarily set depending on the size of the cart.

As is clear from the above description, according to the counter-transfer loading device according to the present invention, ceramic bodies stacked in a stacked manner on a cart can be automatically and quickly and efficiently reversed and placed horizontally. It is possible to do so.

Therefore, for example, a group of ceramic bodies taken out of a drying furnace or an unglazed furnace can be continuously transported to the glazing process as is, so that the conventional effort of using a large box or the like is no longer necessary. In other words, it is not just a fool's errand that eliminates all the drawbacks of large boxes, but it can also be said to be a revolutionary invention in terms of cost and production efficiency, as the introduction of this device makes it possible to make ceramic production lines unmanned. .
