First, the plate portion 110 is provided to the side guide 30. Specifically, the upper portion of the plate portion 110 is hinged to the side guide 30, and the lower portion of the plate portion 110 is rotatable about the upper hinge portion. However, it means that the rotation does not rotate 360 degrees but can be lifted to such an extent as to form an acute angle of 45 degrees or more from 0 degree, as shown in Fig. The acute angle herein means that the angle formed between the rear surface of the plate portion 110, that is, the side not facing the work 1 and the front surface of the side guide 30 is an acute angle.

The angle adjusting unit 120 adjusts the angle of the plate unit 110 provided on the side guide 30. The detailed description and subcomponents thereof will be described after the plate unit 110 is explained.

The plate portion 110 may include a fold plate 111 and a hinge pin 113.

As shown in Fig. 3, the overlapping plate 111 is provided on the surface facing the work 1, and the upper portion is hinged to the side guide 30 to raise the lower portion, as described above.

The overlapping plate 111 allows the material 1 to face the material 1 directly or indirectly in contact with the front surface so as to center the material 1 to be transported from the center of the transporting roll 10, As shown in Fig. 5, the overlapping pawls 111 also serve to support the asymmetric material 1 on both sides thereof, so that the right and left balances of the material 1 are aligned, .

3 and 4, the hinge pin 113 is protruded from upper portions of both side surfaces of the double plate 111 so that the upper portion of the double plate 111 is hinged to the side guide 30. Of course, in this case, the side guide 30 may be formed with a holding frame 114 for holding the hinge pin 113.

It is preferable that the overlapping plates 111 are disposed on each of the side guides 30 disposed on both sides of the work 1 and each of the overlapping plates 111 may be independently controlled in angle, The balance of the material 1 can be adjusted and the material 1 shifted to one side can be conveyed centered on the conveying roll 10 and the turning roll 11. [

The overlapping plate 111 may further include a roller 112 on the front surface in contact with the work 1 to minimize the frictional force with the work 1.

The rollers 112 are formed on the front surface of the double layer 111 and are configured to contact and roll as the work 1 advances.

It is preferable that the rollers 112 are provided in plural as shown in FIG.

It is preferable that a plurality of these rollers 112 are brought into contact with the raw material 1 and rolled manually according to the movement of the raw material 1 rather than aggressively rolling the raw material 1. [ This is because, if the rolling speed of the transfer roll 10 is different from the rolling speed of the roll 112, the unnecessary friction can be generated in the material 1. [

It is preferable that the overlapping plate 111 is made of a heat resistant material due to the high temperature characteristics at which the equipment is exposed and friction can be generated directly or indirectly to the material 1, So that no other scratches are generated on the substrate 1.

A collision may occur on the front surface of the side guide 30 when the double layer plate 111 is lifted upward and then downward. To prevent the impact, the double layer plate 111 has a buffer part 115 .

3 to 5, the buffer part 115 is formed on the rear surface of the double plate 111, that is, on the surface facing the side guide 30, and contacts the side guide 30 Absorbing impact between the overlapping plate 111 and the side guide 30 is absorbed.

Although the buffering portion 115 is configured to be exposed to a lower temperature than the double-layered sheet 111, a relatively high temperature of 80 to 90 degrees Celsius, a material such as a general foamed resin is not preferable, And a foamed molding resin made of a heat resistant material or the like.

When the buffer part 115 is formed on the double layered plate 111, a surface that is in contact with the front surface of the side guide 30, that is, the double layered plate 111 and is in contact with the rear surface of the double layered plate 111 It is preferable that a concave groove h1 capable of contacting the buffer part 115 is formed. However, it is preferable that the groove h1 is concave smaller than the protruded height of the buffer part 115, so that the buffer part 115 can function properly.

Hereinafter, the angle adjusting unit 120 will be described in detail.

4, the angle adjusting unit 120 is disposed at a lower portion of the side guide 30. More specifically, the angle adjusting unit 120 presses the lower portion of the overlapping plate 111 so that the upper portion of the overlapping plate 111 is hinged And the lower portion of the overlapping plate 111 is raised.

The angle adjusting unit 120 may include a cylinder 121. The cylinder 121 may be a hydraulic cylinder or the like and may be controlled by a central system or the like via a network or the like.

The cylinder 121 is fixed in a state of being inserted into the opening h2 formed in the lower portion of the side guide 30 and the length of the cylinder 121 is expanded and contracted to press the lower portion of the overlapping plate 111 to lift the overlapping plate 111 upward .

When the cylinder 121 lifts the folding plate 111, the lower back surface of the folding plate 111 can be pressed. However, when the lower portion of the folded folding plate 111 is lowered, the cylinder 121 simply contracts The hinge-connected overlapping plate 111 can be lowered by its own weight.

When the lubricating ability of the hinged portion is lowered and foreign matters are stuck to the corresponding portion, the overlapping plate 111 may not be restored due to its own weight. The cylinder 121 may have a length There is a need to positively lower the lower portion of the overlapping plate 111 by a force acting thereon.

To this end, it is preferable that the lower portion of the rear face of the double plate 111 and the cylinder head 122 of the cylinder 121 are fastened like a pin connection. However, in this case, due to the expansion and contraction of the cylinder 121, the position of the pin connecting portion is changed due to a geometrical cause. The opening 122h formed in the cylinder head 122 is formed as an ellipse, The pin 122-1 formed at the lower portion of the rear surface of the opening 122h may be inserted so as to be spaced apart from the opening 122h.

The scope of the present invention is defined by the claims, the parentheses used in the claims are not used for optional limitation but are used for the definite components and the description in parentheses is also interpreted as an essential component .
