Description

[Detailed Description of the Invention] This invention relates to a transfer device for an uncured inorganic extrusion molded product.

BACKGROUND ART Conventionally, it has been widely known and practiced to manufacture inorganic molded products mainly composed of cement, gypsum, etc. by extrusion molding.

By the way, unlike synthetic resins, the inorganic hybrid material used as the molding material for the above-mentioned inorganic molded product cannot be rapidly cured by applying heat treatment after extrusion molding.
Transfer immediately after molding must be carried out carefully to avoid deformation due to external forces.

That is, as shown in FIG. 1, conventionally, after extrusion molding an inorganic kneaded material G, it is cut into appropriate dimensions with a cutting blade A.
When transferring the molded product G' to the curing process (not shown), it is customary to transfer the molded product G' onto a pallet B, but in order to reduce the gap between the belt conveyor C and the pallet B,
Even if the inclined belt conveyor E is used, the molding material is placed in two places E.
t, E2, and due to the internal stress caused by the extrusion pressure remaining in the extruded product G' at this time, the molded product G' is bent near the cut portion as shown in FIG.
was often deformed.

In order to solve such difficulties, the applicant of the present application arranged the pallets B against each other to form a series of belts, transferred the extruded inorganic mixed material G onto the belts,
We proposed a device that cuts the pallets after they are transferred to the top, but when the pallets B are butted against each other and arranged, the row of pallets B is slightly accelerated in the advancing direction due to the collision of pallet B1, and this impact causes the forming There were concerns that the part of the product being transferred could become deformed.

In view of the above, it is an object of this invention to provide a transfer device for uncured inorganic extrusion molded products, which can minimize the impact caused by collision when pallets are arranged in a series, and which will not cause deformation of the molded products. A roller conveyor is provided below the end of the belt conveyor, and pallets are arranged in series on the roller conveyor in a series of abutting positions, and are transported at a speed synchronized with the belt conveyor. The belt conveyor is characterized in that the roller diameter of the roller conveyor at the supply start end side of the pallet is gradually larger than that at the lower end of the belt conveyor.

Next, this invention will be explained using examples.

FIG. 3 is a side view of an embodiment of this invention.

The device 1 for transferring an uncured inorganic extrusion molded product of this invention is as follows:
A roller conveyor 5 is provided below the end of a belt conveyor 4 which is disposed continuously to the discharge port 3 of the extruder 2 for extrusion molding the inorganic mixed substance G, and on this roller conveyor 5 pallet bodies 6... 6 are arranged in a series of butts, and the arrow P is moved at a speed synchronized with the belt conveyor 4.
The diameter d of the roller 5' of the roller conveyor 5 at the supply start end 5A side of the pallet body 6 is gradually larger than that at the lower end of the belt conveyor 4. ing.

In the figure, reference numeral 7 denotes a motor for driving the roller conveyor 5, and the motor 7 rotates each roller 5' at the same rotational speed.

A cutting blade 8 is provided to cut the molded product G' on the pallet 6 at the butt joint of the pallet 6.

Next, the operation of the embodiment of this invention will be explained.

Molded products G' extruded from the extruder 2 and sent out by the belt conveyor 4 are sequentially transferred onto pallets 6... , the pallet 6 is fed to the starting end 5
When placed on the A side, the pallet 6 is transported at a high speed even though the outer diameter d of the roller in this portion is increased, and the speed gradually decreases as the diameter of the roller 5' changes.

At this time, the speed of the pallet 6 decreases as it approaches the pallet 6' located in front, and at the time of the butt, the speed is almost the same as that of the preceding pallet 6', so the impact at the time of the butt is almost eliminated. be.

Incidentally, the interval S between the pallets 6 at the supply start end is the distance between the rollers 5'
Although it is determined by the rate of change in the diameter of the pallet 6, it is preferable that the feeding interval of the pallets 6 be within a certain value S.

That is, by feeding in this manner, the pallets 6 are transported while maintaining the state in which they are butted against each other, and since the rollers 5' slip on the surfaces of the pallets 6, there is no risk of excessive pressing force being applied, and the pallets 6 However, this is because it is possible to effectively prevent impact from occurring.

This invention is constructed as described above, so when pallets are butted together and connected in series, the rollers that gradually change diameter allow the trailing pallet to approach the preceding pallet relatively quietly. The molded products are butted together without any impact, which makes it possible to transfer the molded products in the direction of transport without giving any shock to them.Furthermore, the transport speed of the roller conveyor can be changed by changing the diameter of the rollers. This method has various practical effects, such as requiring only one type of drive device and simple equipment.
