Description

Rotary lift cutter {rotated and lifted cutter}

The present invention relates to a rotary lifting type cutting device for cutting a glass fiber mat, which is a heat insulating material for a sandwich panel, in a direction perpendicular to the fiber layer forming surface, into a plurality of three pieces. More specifically, the glass fiber mat may be formed of a plurality of cutters. The present invention relates to a rotary lifting type cutting device that can be cut into a plurality of three pieces by selectively using any one cutter.

In general, sandwich panels are filled with insulation such as mineral fiber boards such as rock wool or glass wool. However, the sandwich panel has to be molded in different thicknesses according to its use, and for this purpose, the insulation is cut to different widths to correspond to it and then rotated by 90 ° in the subsequent process to be inserted and filled between the upper and lower steel plates. do.

The cutting device of the glass fiber mat, which is required for the production of the sandwich panel, is configured such that a cutter unit installed to cross the transport path of the glass fiber mat is rotated by a drive motor, and the cutter unit is installed to cross the heat transport material path. The rotating shaft and a plurality of circular cutters fixed on the outer circumference of the rotating shaft at predetermined intervals with respect to the longitudinal direction of the rotating shaft.

Therefore, when the glass fiber mat is cut by the cutting device, the glass fiber mat is cut to a width corresponding to the gap between the circular cutters.

However, in order to control the cutting width of the glass fiber mat by such a cutting device, a plurality of fixing means for fixing the cutter unit to the frame is dismantled one by one to separate the cutter unit, and then the other one having a different interval between the circular cutter blades. The removal and removal work such as replacement with the cutter unit is cumbersome, and the work of other processes must be stopped during the replacement of the cutter unit, which reduces the productivity of the product and pauses the manufacturing process of the sandwich panel, which must be produced continuously. Therefore, when restarting, there are various problems such as cutting raw materials such as steel sheets to a certain length.

Therefore, recently, a plurality of cutter units having different spacings between the circular cutter blades are arranged in a row so as to be liftable under the transport path of the glass fiber mat, thereby selectively raising and lowering the cutter units having the desired spacing between the circular cutter blades. A lifting type cutting device that can cut a glass fiber mat has been developed and used. This lifting type cutting device, as shown in Figure 1, simply by up / down the cutter unit 30 of the desired interval by the lifting means 80, it is possible to easily adjust the cutting width of the glass fiber mat is convenient to use There is this.

However, such a lifting type cutting device is arranged in a row in each cutter unit 30, the expensive drive motor 35, the dust discharge duct 70, the cutter unit lifting means 80 including the lead screw 83, etc. in a row. Since the number of parts, the equipment is enlarged, there is a problem that the manufacturing cost, maintenance cost of the cutting device accordingly increases.

In order to prevent this, a plurality of cutter units having different spacings between the circular cutter blades are arranged on a predetermined circumference so as to be rotatable about one central axis under the transport path of the glass fiber mat, so that the interval between the desired circular cutter blades can be adjusted. A rotary lifting type cutting device has been developed and used to cut the glass fiber mat by selectively rotating the rotary shaft so that the rotating shaft of the excitation cutter unit is located at the highest point. This rotary lifting type cutting device rotates the cutter unit at a desired interval about the central axis so that the rotary shaft of the cutter unit is at the highest point, and then advances the spline or key of the clutch means connected to the rotary shaft drive motor, thereby rotating the rotary shaft positioned at the highest point. By selectively combining with, and only driving the rotary shaft located at the top, there is a convenient advantage that can easily cut the glass fiber mat to the desired cutting width, as well as compared to the conventional cutting device arranged in a row of circular cutters The number of parts is reduced, and the equipment is reduced, thereby reducing the manufacturing cost and maintenance cost of the cutting device.

However, in the rotary lifting cutting device, the spline or the key of the clutch means must be reversed when the rotary shaft is divided and rotated so as to position the rotary shaft of the cutter unit having the interval between the desired circular cutter blades at the highest point, and the desired circular Since it must be advanced when driving the rotary shaft of the cutter unit with the gap between the cutter blades, the drive means for driving the spline or key of the clutch means and the control means for controlling the same, it is necessary to further reduce the number of parts In addition, there is a problem that high precision positioning control is required for coupling and disengaging of the spline or key of the clutch means and the rotational shaft.

The present invention has been made to solve the problems as described above, when the rotary shaft of the cutter unit having the interval between the desired circular cutter blades at the highest point, the glass configured to engage with the drive gear for automatically driving the rotary shaft without the clutch means It is to provide a rotary lifting cutting device for the fiber mat.
