Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for conveying a continuous extruded body, and is useful for conveying a continuous body when cement is extruded into a continuous body.

When continuously extruding cement strips using an extruder, the compacts may be placed on continuously fed pallets and transported, but by the time the compacts are placed on the pallets, there is a A gap may occur in the cement strip, and the cement band-shaped compact may fall into this gap, causing cracks in the compact.

The method for conveying a continuous extrusion molded body according to the present invention is a method in which a continuous extrusion molded body can be conveyed by a pallet without returning the above-mentioned cracks, and the continuous extrusion molded body from an extruder is continuously fed. In the method of placing the extruded product on a pallet and transporting it, the position where the extruded molded product is placed on the pallet
The movement of the pallet from the rear to the front of the extruded body conveyance is carried out at the same speed as the extruder speed and by a synchronized conveyor that operates in conjunction with the extruder speed, and the pallet is moved between the rear position and the pallet supply position. This method is characterized in that the movement is carried out at a speed slightly higher than the speed of the extruder and by a rapid conveyor that operates in conjunction with the speed of the extruder.

The present invention will be explained below with reference to the drawings.

In the figure, 1 is an extruder.

2a, 2b, 2c, . . . are continuously supplied pallets.

3 is an extruded body receiving rechelt conveyor, and 4 is an auxiliary roll conveyor.

P is a strip-shaped cement product continuously extruded from an extruder, placed on a continuously supplied pallet at position A, and thereafter transported by this pallet.

Reference numeral 5 denotes an extrusion speed detector, which is provided immediately after the die of the extruder 1 and includes, for example, an endless belt that rotates to follow the extruded product without slipping, and the rotation of this belt is transmitted to a speed generator.

61 is a position A slightly behind the mounting position A of the molded body.
.

This is a synchronized roll conveyor that takes part in the movement of the pallet from the to the front of the molded body conveyance, and is operated at the same speed as the extruder speed and in conjunction with the extrusion speed based on the output signal of the extrusion speed detector 5. .

62 is the rear position A mentioned above. This is a rapid roll conveyor that takes part in the movement of pallets between the pallet supply position A1 and the pallet supply position A1, and is driven at a speed slightly higher than the extruder speed (several percent to 10% faster) according to the output signal of the extrusion speed detector 5. , and is operated in conjunction with the extrusion speed.

Therefore, since the pallet 2b following this pallet moves at a faster speed than the pallet 2c on which the cement 1 [shaped body P is placed], it is possible to prevent gaps between the pallets.

Furthermore, if the extrusion speed changes, the speed of the pant 2c on which the extruded product P is placed also changes immediately in response to the change (because the synchronized conveyor 61 is linked to the speed of the extruder). , there is no generation of tensile or compressive stress in the extruded body due to changes in extrusion speed.

In this case, the pant) 2b that follows the pant) 2c on which the extrusion molded product is placed also changes immediately in response to changes in the extrusion speed (the rapid conveyor is linked to the speed of the extruder). ), there is no fluctuation in the force of the pallet 2b pushing the pallet 2c, and the pallet 2 on which the extrusion molded product is placed
It is possible to maintain synchronization between c and extrusion speed.

As described above, according to the present invention, continuously extruded molded bodies from an extruder are conveyed by continuously feeding pallets, eliminating the generation of gaps between pallets, and ensuring synchronization between the pallet conveying speed and the extruder speed. It is possible to go.

Therefore, the generation of gaps between pallets causes clutches in the compacts, and even a slight deviation in the synchronization causes significant tensile and compressive strains in the compacts, making it extremely useful for conveying cement continuous extrusion compacts. .

2 is a rapid conveyor.

Claims (1)

[Claims] 1 In a method in which continuously extruded molded bodies from an extruder are placed on a continuous supply pallet and transported, the extruded molded bodies are transported from the position behind the position where the extruded molded bodies are placed on the pallet to the front of the extruded molded body conveyance. The pallet is moved between the two locations by a synchronized conveyor that operates at the same speed as the extruder speed and in conjunction with the extruder speed, and the pallet is moved between the rear position and the pallet supply position at a speed that is faster than the extruder speed. A method for conveying a continuous extrusion molded article, which is carried out at high speed using a rapid conveyor that operates in conjunction with the extruder speed.
