Description

Device for rotating a plurality of cut pieces at an angle of 90 degrees}

The present invention cuts a plurality of cut pieces formed by laminating a plurality of mineral fiber sheets and forming a plurality of mineral fiber boards used as fillers in sandwich panels in a thickness direction in a predetermined size, and streaks formed by laminating a plurality of mineral fiber sheets. The present invention relates to a device for rapidly rotating 90 ° so as to be in the longitudinal direction and the thickness direction of the piece.

In the existing sandwich panel used as a wall of a building, styrofoam excellent in sound insulation, heat insulation, and strength is inserted as a filler between the two plates. However, Schirofoam, which is the filler, does not have fire resistance, and thus has a disadvantage in that the building easily burns out when a fire occurs in the building.

Therefore, in order to overcome the above disadvantages, instead of the filler of the styrofoam material in the sandwich panel, a board made of mineral fiber material having excellent fire resistance has been used as a filler until now.

The board of the mineral fiber material used as the filler in the sandwich panel is a board in which the sheets of the mineral fiber material are stacked in multiple layers. This board is small in strength in the direction perpendicular to the ply and is not suitable as a component of a sandwich panel.

Therefore, the board is cut into a plurality of equally cut pieces cut in the longitudinal direction by equally distributed from the left side to the right side direction or from the right side to the left side direction, and in front of the plurality of cut pieces cut in the horizontal direction or In such a way that the back sides are bonded to each other by an adhesive, it is necessary to modify the structure to have a strength greater than the original strength.

Structural modification treatment process for making the mineral fiber board to have a greater strength is usually a step of cutting the mineral fiber board into a plurality of cut pieces, the step of rotating the plurality of cut pieces 90 °, the plurality of rotated 90 ° Joining the cut pieces to each other, cutting the plurality of cut pieces joined to each other to a predetermined standard, and stacking the plurality of cut pieces cut to a predetermined standard.

Among the various steps, the cutting device 10 for performing the step of cutting the mineral fiber board to make a plurality of cut pieces and the cutting piece rotating device 20 for performing the step of rotating the plurality of cut pieces 90 ° 1 is shown.

As shown in FIG. 1, the mineral fiber board 2 is cut by the cutting device 10, made into a plurality of cutting pieces 2 ′, and then transferred to the guide conveyor 30. The plurality of cutting pieces 2 'transferred to the guide conveyor 30 are rotated by the guide conveyor 30 while the cutting pieces 2' are cut by the cutting device 10. 20).

The cutting piece rotating device 20 has a first conveyor 21 and a second conveyor 22 at a level lower than that of the first conveyor, as shown in FIG. 1. In addition, as shown in FIG. 2, the second conveyor 22 has a carrier wall 24 fixed to the belt 23 at a predetermined interval, and the first conveyor 21 is attached to the second conveyor 21. The plurality of cutting pieces 2 'to be transported are separated by a predetermined interval and then transferred to the next process.

The process of transferring the plurality of cutting pieces 2 'from the first conveyor 21 to the second conveyor 22 while rotating by 90 ° will be described in more detail as follows.

First, the state in which the cutting piece 2 'is empty in the space A partitioned by the carrier wall 24 of the second conveyor 22 located closest to the first conveyor 21 side is not shown. The first step of checking with a non-shown first sensor and confirming the state in which the cutting member is loaded on the first conveyor 21 with a second sensor (not shown), operates the first conveyor 21 for a predetermined time. (2 ') A second step of stopping the first conveyor 21 after dropping one on the second conveyor 22, that the separated cutting piece 2' is loaded on the second conveyor 22. The third step of operating the second conveyor 22 for a predetermined time and the second and third steps are repeated to check with the first sensor and to receive the next cut piece 2 '. When 2 'is transferred to the second conveyor 22, the desired number of cutting pieces 2' is transferred to the next step. It includes the step of.

As described above, in the conventional process of transporting the plurality of cutting pieces 2 'while rotating by 90 °, the mineral fiber board is cut by the cutting device 10, and then transferred by the process of being rotated by 90 °. Although the mineral fiber board is cut by the cutting device 10 into a plurality of cut pieces, the plurality of cut pieces are not spaced at regular intervals, so that the fiber grains formed on the plurality of cut pieces Since (stripes) are tangled with each other so that the plurality of cut pieces are in contact with each other so that they cannot be easily separated from each other, the plurality of cut pieces are moved with respect to each other when moved from the first conveyor 21 to the second conveyor 22. There is a problem that is not easily separated naturally.

In addition, when the plurality of cut pieces fall from the first conveyor 21 to the second conveyor 22, the cut pieces fall on the top surface of the belt 23 of the second conveyor 22 so that the cut pieces fall into a uniformly arranged shape. Although the space partitioned by the carrier wall 24 arrange | positioned at regular intervals was provided, even after cutting of the board, a plurality of cut pieces are stuck together by fiber grain, and the plurality of cut pieces are long rod-shaped, Not only the plurality of cut pieces could not be accommodated in the space partitioned in the second conveyor 22, but rather, the first conveyor and the second conveyor were alternately used to sequentially receive the cut pieces in the partitioned space. Since the first and second conveyors must be repeatedly started and stopped since the cutting pieces must be transported in order to move the cutting pieces sequentially, the working time is long. , There is the problem of low productivity.

Accordingly, the present invention has been made to solve the above problems, the belt is moved in a rectangular shape and the carrier wall is formed on the belt so that the plurality of cut pieces of the mineral fiber board discharged from the cutting device are separated from each other and transported It is to provide a plurality of cutting piece rotating device having a second conveyor.
