Abstract

PURPOSE:To prevent a large-sized tile from development of cracking by transferring the tiles onto a pallet using a transferring device including a lift device when the tile is to be moved from the pre-process to the post-process in a tile manufacturing line. CONSTITUTION:A large-sized tile 10 fed by a roller conveyor 12 is placed on a conveyor device 14 and passed forward with traveling of a conveyor belt. When the tile 10 reaches a specified place, a pallet 18 positioned under the conveyor device 14 is raised by an elevating/sinking member together with a movable rail piece. Therein the tile 10 on the conveyor device 14 is transferred onto a support bar. The pallet 18 on which the tile 10 is placed is sent for a drying room 24 of a roller hearth kiln 22. The pallet 18 is discharged from the drying room 24 and transferred onto another conveyor device 32 at over stage by a transferring device 30, while emptied pallet 18 is sunk by a sinking device 36 and sent back to the right along the transport path in the lower stage.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a transfer device suitable for use in transferring large tiles.

(Prior Art) In the tile manufacturing process, in order to transfer a tile molded body as an intermediate product from a previous process to a subsequent process or for other purposes, it is possible to transfer it from a delivery body to a receiving body. It is being done.

As shown in FIG. 12, a commonly used transfer device is one that presses a suction head 100 against a tile molded body 102 and applies vacuum suction, thereby transferring it to the suction unit. 100, the entire suction device 104 is moved from the delivery body onto the receiving body, and then the suction is released and the tile molded body 102 is transferred to the receiving body.

(Problem 11i to be solved by the invention) However, in the case of this transfer device, the suction head 100 is strongly pressed against the tile molded object 102, which is the object to be transferred, and in this case, each suction head lOO is not necessarily attached to the tile molded object. Since the tile molded body 102 is not pressed with an even force, a strain force is applied to the tile molded body 102, causing cracks, or cracks occur when fired, although no external damage is observed at the stage of the molded body. There was a problem with doing so.

As shown in FIG. 12, this phenomenon is particularly likely to occur when transferring large tile molded bodies with large dimensions (about 300 mm square or more in size), and has been viewed as a problem.

(Means for solving 8181) (First solution) The invention of the present application has been made to solve such problems, and its gist is to transfer objects from a delivery body to a receiving body. In the transfer device, the transfer body is configured such that a plurality of support parts are arranged in parallel with a predetermined gap between the support parts, and an object to be transferred is supported on the support parts. On the other hand, the receiving body is constructed by arranging a plurality of supporting parts that can be inserted into gaps between the supporting parts at intervals corresponding to the intervals between the gaps, and each supporting part of the receiving body is The object to be transferred on the delivery body is scooped onto the receiving body by inserting it into the gap between the respective support parts of the delivery body and moving it upwards relatively. Claim 1))

Claim (6) characterized in that the object to be transferred is transferred by scooping it onto the pallet.
.

(Seventh solution) The seventh solution of the present application is related to a conveying device, which includes an outgoing path along the upper fixed rail and a return path along the lower fixed rail for carrying the pallet of claim (5). The transfer according to claim (6), wherein the movable rail piece is arranged adjacent to the upper and lower fixed rails, and the movable rail piece is lifted by the lifting device. The plurality of belt conveyor units/
Claim (7)) characterized in that the object to be transferred on the conveyor device including tt is transferred onto the pallet and then horizontally moved along the outgoing path of the upper stage.

(Eighth Solution Means) The eighth solution of the present application relates to a drying device, in which a large tile molded body as the plate-like object is transported in a drying path by the conveyance device of claim (7), and the following Claim (action and effect) characterized in that the molded body is subjected to a drying treatment by drying the molded body. Similarly, the object to be transferred is scooped up by a receiving body configured to have a plurality of support parts, and the object to be transferred is transferred from the delivery body to the receiving body.

According to the device of the present invention, unlike conventional transfer devices, the object to be transferred is not pressed from above, so no excessive force is applied during transfer, and therefore, the object to be transferred is There will be no problems such as breaking the object, creating internal stress and distortion, and later causing damage such as cracks or chips. Therefore, the present invention
Conventionally, plate-shaped objects were particularly prone to cracking during transfer,
It is particularly effective when applied to a transfer device for large tile molded bodies that have not yet developed strength and are susceptible to distortion (Claims (2) and (3)).

The invention of claim 0 is such that one of a conveyor device comprising a plurality of belt conveyor units arranged side by side at a predetermined interval and a pallet comprising a plurality of support bars arranged side by side at corresponding intervals constitutes a delivery body, and the other The recipient is the recipient.

The apparatus of the present invention differs from conventional transfer apparatuses in which an object transported by one transport means is once sucked and held in a suction device, and then transferred to the other transport means. Since the transferred object is directly transferred from one conveyance means to the other conveyance means, there is little wasted movement, and the transfer can be carried out smoothly and quickly. Simplify.

The invention of claim (5) relates to a pallet, and the pallet of this invention has wheels on a base frame and also serves as a trolley. It is possible to transport quickly and smoothly.

The invention according to claim (6) lifts the pallet that also serves as a cart together with the movable rail pieces, inserts each support frame of the pallet into the gap between the belt conveyor units at the rising end, and then relatively moves the pallet upward. A device in which objects to be transferred on a conveyor device are received on a pallet,
That is, it is designed to be transferred onto a pallet, and in this way, the objects to be transferred can be automatically transferred during the process of moving the pallet from the lower tier return trip to the upper tier outward trip. In other words, the process of moving the pallet from the return path to the outbound path and the process of transferring the objects to be transferred can be performed at the same time.This eliminates waste in the operation and facilitates the transfer and transportation of the objects to be transferred. Possible benefits arise.

The invention of claim (7) relates to a transport device including the above-mentioned transfer device, and according to the present invention, an object to be transferred can be transferred and then immediately transported together with the valet.

According to the invention of claim (8), it is possible to continuously dry the tile molded body as the object to be transferred by the conveying device in the process of conveying it together with the pallet.

(Example) Next, embodiments of the present invention will be described in detail based on the drawings.
