Abstract

PURPOSE:To obtain the same effect as that of a multistages stack in a device for transferring workpieces to a pallette dry furnace, by providing such an arrangement that the transferring device is driven by a chain while pallettes being guided with the repetition of horizontal transfer and turn within a vertical plane. CONSTITUTION:A motor 9 rotates right and left sprockets 3, synchroneously with each other, to drive a chain 2 to transfer pallettes 1 fixed to the chain 1. In the rectilinear transfer section rollers 6 of the pallettes 1 roll and travel on a guide rail 7, and in the vertical descending section the pallettes 1 are supported by two points under tension which is exerted to the chain 2 by the sprockets 3. That is, the pallettes 6 are transferred by being successively rotated in the combination of two point support by the chain 2 and three point support by guide rings 9 and rollers 6. With this arrangement, it is possible to aim at effectively utilizing the drying space in the furnace.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parallel conveyance system for pallets, and more particularly to a conveyance system for a drying oven for drying works on pallets.

In order to continuously dry pallets of workpieces from a molding machine lined up manually or with a handling device, it is common to dry the pallets by blowing temperature-controlled air from a direction perpendicular to the direction of conveyance while conveying the pallets with a conveying device. It is true. However, if pallets are transported one by one, the area occupied becomes large and the installation space is used inefficiently (the drying efficiency is also poor because the drying cross-sectional area is small).

Conventionally, as a countermeasure, pallets were stacked in multiple stages and dried while being transported. However, in order to stack pallets after arranging workpieces in multiple tiers and take out the workpieces from the stacked pallets after drying, it is necessary to have a device that stacks the pallets in multiple tiers and a device that separates the stacked pallets one by one. At that time, there was a risk that the workpiece would fall and become deformed due to the shock. When the pallets are piled up in multiple stacks, the height increases, which has the disadvantage that the pallets themselves tend to topple over.

Another method is to use a multi-stage button on the transport path to transport the pallet independently, or use a special cam to transfer between each stage, but this would complicate the transport system, increase costs, and The disadvantage was that the shape of the

The present invention eliminates these drawbacks, and uses space three-dimensionally by guiding a pallet on which molded bodies are lined up while being driven by a chino, and repeating horizontal conveyance and rounding within a vertical plane. It is an object of the present invention to provide a conveying device that continuously conveys pallets one by one and has the same effect as multi-tiered stacking.

The features of the present invention are that pallets are rotatably attached to a cheno that is conveyed in parallel by shifting the mounting pitch, and that guide rails and guide links are installed in the linear conveyance section and rotating section to convey the pallets so that they are always horizontal. There is a particular thing.

An embodiment of the present invention will be described below with reference to the drawings.

Here, FIG. 1 is an overall perspective view of one embodiment, and FIG. 2 is an overall perspective view of one embodiment.
74 rotation section, FIG. 3 is a schematic diagram of the 1/2 rotation section. In the figure, 1 is a pallet, 2 is a driving chino, 3 is a tin rocket,
4 is a guide roller that receives the cheno, 5 is a guide ring that guides the pallet reroller, 6 is a pallet roller,
7 is a guide rail, 8 is a take-up section, 9 is a drive motor, and 10 (indicates a drive system).

In the above configuration, in order to convey the pallet, the drive motor 9 is driven, the left and right sprockets 6 are synchronously rotated via the drive system 10, the left and right drive chinos 2 are synchronously driven, and the left and right drive chinos 2 are synchronously driven. A pallet 1 pinned to a cheno 2 is transported. In the linear conveyance section, the pallet 10a-26 rolls on the guide rail 7, so it is supported at three or four points and is stably conveyed while maintaining a horizontal position. At the vertically descending part, tension is applied to the drive chino 2 by the driving force from the sprocket 6, and although it is supported at two points, it has a horizontal maintenance function.

At the 1/4 rotation section, the paper is supported and conveyed at two points due to the tension support and at three points due to contact between the guide link 5 and the roller 6. At the 172-rotation section, it is supported at two points by the chino support and three points by the contact between the inner ring or outer ring of the guide link 5 and the row 26, and is conveyed while going around. The conveying device is covered, and the molded bodies on the pallet are dried by blowing temperature-controlled air from a direction perpendicular to the direction of conveyance, and the works arranged on the uppermost surface are rotated once and taken out when they reach the uppermost surface. The conveyance device according to the present embodiment is capable of conveying a pallet attached to a cheno to be conveyed in parallel while maintaining the pallet horizontally by guiding it using a kite rail and a guide link.

As described above, the conveyance device according to the present invention has advantages such as being able to effectively utilize drying space with a simple conveyance mechanism, without having to keep the pallet horizontal while conveying it around the pallet in multiple stages. It has the following.
