Abstract

PURPOSE:To re-charge even a soft material to be kneaded in a well-balanced state without generating the collapse of a shape by converting the direction of the substance kneaded by rolls by a turntable and again charging said substance in the rolls by a conveyor. CONSTITUTION:A conveyor 2 whose length is slightly longer than the width of each roll 1 and whose width is almost same to that of the roll 1, the freely rotatable turntable 3 supporting the conveyor 2 and a lift apparatus 4 moving the turntable 3 up and down are mounted to be arranged by the roll 1. At first, the conveyor 2 receives a material (a) to be kneaded from the roll 1 on the upper surface of the lateral half part thereof at a position where the conveyor 2 falls in a posture parallel to the roll 1. Next, the conveyor 2 is rotated by 180 deg. and receives the material (a) to be kneaded on the upper surface of the remaining lateral half part thereof from the roll 1. Subsequently, the conveyor 2 is rotated by 90 deg. at a rising position and a belt 5 is driven to allow the material (a) to be kneaded to drop and charge the same on the roll 1. Thereafter, the conveyor 2 is rotated by 90 deg. to again fall in a posture parallel to the roll 1 to complete a process of one cycle.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an apparatus for changing the orientation of a substance kneaded by rolls and feeding it again to the rolls.

(Prior Art) When kneading a substance using rolls, if the substance is passed through the rolls only once, the substance will only be stretched in one direction, resulting in insufficient cross-mixing. Therefore, it is necessary to increase the degree of kneading by changing the direction of the material that has been kneaded and feeding it into the rolls again.

Conventional devices for this purpose include those shown in FIGS. 4 to 6. This device consists of a rectangular chute (6) whose length is slightly longer than the width of the roll (1) and whose width is narrower, and a rotating table (3) that supports the chute (6) on one side of the upper surface and is rotatable. ), a lifting device (4) that moves the rotating table (3) up and down, and a seat (6) in the raised position.
and a pair of scraping plates (7) that can be advanced toward the roll (1) by entering inside the roll (1), and installed near the roll (1);
First, shoot (6) is in a posture parallel to roll (1) (6th
(See Figure (a)) and in the lowered position, the material to be kneaded (A) is received and taken from the roll (1) (See Figure 4), and then the chute (6) is in the raised position and rotates 900 times to the left. and roll (
In a state perpendicular to 1) (see Figure 6 (b)), the scraper plate (7) advances to push out the material to be kneaded (a) and drop it onto the left half of the roll (1). (See Figure 5)
Next, at the position where the chute (6) is again parallel to the roll (1) and lowered, the material to be kneaded (
(a), and then, with the chute (6) in the raised position, rotate it 90' clockwise in the opposite direction to take a position perpendicular to the roll (1) (see Figure 6 (c)). (7
) moves forward again and pushes out the material to be kneaded (a) and rolls (
1), and then shoot again (
6) was configured to return to the original state (see FIG. 6 (dJ)) and complete the 1-cycle process.

(Problem to be solved by the invention) The above conventional device has the following drawbacks.

First, the material to be kneaded (
When the material (a) is dropped, the material to be kneaded (a) is pushed out by the scraping plate (7) K, so if the material to be kneaded (a) is a hard material, the directionality can be maintained in a sheet form. Although this is not a problem, if the material to be kneaded (a) is a soft material, it loses its shape and directionality when pressed by the scraping plate (7), so there is a drawback that direction change cannot be achieved. Next, when dropping the material to be kneaded (a) from the shoe (6) onto the roll (1), it is thrown only into the left or right half of the roll (1). The distribution of the material to be kneaded (a) is biased and does not spread uniformly across the entire width of the roll (1).
) may come into direct contact with the kneaded material (a), which serves as a lubricant, without passing through the kneaded material (a), and the resulting frictional heat may cause seizing on the roll (1). Furthermore, the provision of the scraping plate (7) and its auxiliary equipment increases the size of the apparatus.

The present invention is an apparatus that eliminates the above-mentioned drawbacks, that is, even when a soft material to be kneaded is re-introduced into the rolls, the direction of the material to be kneaded can be reliably changed, and the entire width direction of the roll can be The purpose of the present invention is to provide a re-feeding device for changing the direction of kneaded materials in a roll-type kneading machine, which can be re-injected in a well-balanced manner so that the materials to be kneaded are evenly distributed, and furthermore, the device can be made more compact.

(Means for Solving the Problems) In order to achieve the above object, the re-feeding device for changing the direction of the material to be kneaded in the roll kneader of the present invention has a length slightly longer than the width of the roll (1) and a width of the roll (1). A conveyor (2) whose width is approximately the same as the width of the roll (1), a rotating table (3) that supports the conveyor (2) and is rotatable, and a lifting device (4) that moves the rotating table (3) up and down. ) is installed near the roll (1), and first, the conveyor (2) is in a position parallel to the roll (1) K and in a lowered position, and the material to be kneaded is transferred from the roll (1) to the upper surface of the horizontal half of the conveyor (2). (A), then the conveyor (2) rotates 180' and receives the material to be kneaded (A) from the roll (1) on the upper surface of the remaining horizontal half, and then the conveyor (2) moves to the raised position. Rotate 90° and roll (
1), the belt (5) is driven and the material to be kneaded (a) is dropped onto the roll (1),
After that, the conveyor (2) rotates 90 degrees and rolls (1) again.
) is characterized in that it is constructed so that one cycle of travel is completed by descending in a posture parallel to ). , 5° (Example) An example will be described with reference to FIGS. 1 to 3.

A device of the present invention, in which a plurality of rolls (1) are arranged in parallel on the same horizontal plane, and a conveyor (2), a turning table (3), and a lifting device (4) are provided near the rolls (1) at the ends thereof. The conveyor (2) is slightly longer than the width of the roll (1) and has a width that is approximately the same as the width of the roll (1), and a drive motor (8) is disposed at the base end of the conveyor (2) in the longitudinal direction. The belt (5) on the upper surface side is configured to move from the proximal end toward the distal end by opening the opposite end.The conveyor (2) is equipped with a rotating table that can freely rotate in both left and right directions. (3), and the revolving table (3) is further attached to a lifting device (4) that can move up and down.

In the apparatus of the present invention, the conveyor (2) first transfers the material to be kneaded (A) from the roll (1) to its horizontal half in a position parallel to the roll (1) (see Figure 3) and in a lowered position. The receiver is placed on the upper surface of the conveyor (see Fig. 1), and then the material to be kneaded ( 4) is received and received (3rd
(see Figure (1))], then ■ rise and rotate 90' to take a vertical position with its tip facing the roll (1) (see Figure 3 (0)). ) is activated to drop the material to be kneaded (a) onto the syringe roll (1) (see Figure 2), and then return to the state of ■ (see Figure 3 (■)) for one cycle. The conveyor (2) is configured to complete the process.In the above ■, the conveyor (2)
is rotated 1800 times, but this is because there is no rotation space under the roll (1) in the lowered position.
If sufficient rotation space can be obtained under the roll (1), it is of course possible to rotate in the lowered position without raising it.

Effects) The structure of the present invention is as described above. First, when the material to be kneaded is re-injected onto the rolls, the scraping plate of the conventional device described above is used. Since a conveyor is used in step (b), even if the material to be kneaded is a soft material, it will not lose its shape and the direction change will be reliably achieved. 1 after receiving the material to be kneaded on the top surface of the section.
After 800 rotations, the material to be kneaded is also collected on the upper surface of the remaining side part and then re-injected into the roll, so that the material to be kneaded is uniformly distributed over the entire width of the roll without being biased to a part of the roll. It is possible to prevent the roll from seizing, and since there is no need to provide a scraping plate and its attached devices as in the conventional device, the device can be downsized.
