The continuous feeder 30 is provided with at least one pressure roller 31 on one side of the guide 33, and a plurality of feed rollers 32 on the opposite side thereof. The corrugated cardboard 10 passes between the guide portions 33 and between the pressure roller 31 and the transfer roller 32. That is, the corrugated cardboard 10 is introduced into the continuous feeder 30 through ruled lines and the cutter 21, and the cardboard 10 passed through the continuous feeder 30 is inserted into the full coater 22. Here, the corrugated cardboard 10 can be moved by the rotation of the transfer roller 32, it is possible to use a conveyor belt (not shown).

The pressure roller 31 surrounds the roller core member 31b with a rubber roller skin 31a. The roller core material 31b may be a metal material having a high rigidity, preferably iron, and the roller skin portion 31a may be a rubber material. Since the rubber material has a slight adhesive force, the cardboard 10 can be securely grasped and stably transported. The rubber is silicone rubber, fluorine rubber, acrylic rubber, polyurethane rubber, polyamide rubber, natural rubber, polyisobutylene rubber, polyisoprene rubber, chloroprene rubber, butyl rubber, nitrile butyl rubber, styrene-butadiene rubber, styrene- Any one or mixture thereof selected from butadiene-styrene rubber, styrene-isoprene-styrene rubber, styrene-ethylene-butadiene rubber, styrene-ethylene-butylene-styrene rubber, styrene-isoprene-propylene-styrene rubber, chlorosulfonated polyethylene rubber It may be made of.

In some cases, the pressing roller 31 may have a recessed area on the surface of the core material 31b without having the skin portion 31a. The recessed area of the surface generates a frictional force to hold the cardboard 10 and adjust the feed rate. The recess region is formed with a groove or the like, and conceptually includes trenches, grooves, irregularities, and texturing. The recess region may include at least one of various recesses such as trenches, grooves, irregularities, and texturing. The recessed areas are not necessarily limited to the cross-sectional view, but various recessed areas may be singly or combined, such as polygons, arcs, and inclined sidewalls. Similarly, the skin portion 31b can also form the recessed region as described above.

The pressure roller 31 may apply pressure so that the cardboard 10 is not shaken through the linear motion of moving forward or backward with respect to the guide part 33. The pressure applied to the cardboard 10 by the pressure roller 31 may be determined to the extent that the pressure roller 31 moves toward the cardboard 10. That is, when the pressure roller 31 moves a lot, the pressure increases, and when the pressure roller 31 moves less, the pressure decreases. Of course, within the scope of the present invention it may be equipped with a means for regulating the pressure applied to the cardboard (10) by the pressure roller (31). The pressure roller 31 can be manually rotated in accordance with the movement of the corrugated cardboard 10, may be added a separate rotation means in some cases. The diameter of the pressure roller 31 and the thickness of the skin 31a may be set in consideration of the size, thickness, length, material, and the like of the cardboard 10. The pressure roller 31 may adjust the position installed in the guide part 33 in consideration of the size, thickness, length, material, etc. of the cardboard (10).

The guide part 33 may be divided into a guide part inlet 33a, a guide body 33b, and a guide part outlet 33c. The guide part inlet 33a receives the corrugated cardboard 10, and the guide part outlet 33c directs the corrugated cardboard 10 to the gluer 22. The guide part inlet 33a becomes narrower toward the guide part body 33b. When the width is narrowed, the cardboard 10 is stably introduced into the guide body 33b. The point where the guide part inlet 33a and the guide part body 33b meet is a curved surface, so that the movement of the corrugated cardboard 10 can be prevented. The space between the guide body 33b is set to be close to the width of the cardboard 10 so that the cardboard 10 does not shake. The guide part outlet 33c has a gap such that the cardboard 10 is directly supplied to the gluer 22 without any separate alignment. Preferably, the spacing between the guide body 33b and the guide part outlet 33c is the same. At this time, the pressure roller 31 operates in the region of the guide body 33b.

In order to smoothly move the cardboard 10, the guide body 33b has a plurality of guide rollers 34 in contact with the side surface of the cardboard 10 at both sides thereof. Guide roller 34 has a shape such as a cylindrical or spherical bearing, in consideration of the size of the guide body 33b, the feed rate of the corrugated cardboard 10, the size and number can be adjusted. Sensors 35a and 35b capable of checking the conveyance of the cardboard 10 may be mounted on both sides of the guide body 33b. That is, the inlet-side sensor 35a is located in the guide part inlet 33a, and the outlet-side sensor 35b is located in the guide part outlet 33c. Sensors 35a and 35b are preferably optical sensors. By means of the sensors 35a and 35b, the conveying speed of the cardboard 10 can be calculated. If the conveying speed of the corrugated cardboard 10 is low, the rotation of the conveying roller 32 can be accelerated or the pressure of the pressure roller 31 can be reduced.

As such, the pressure roller 31 of the present invention can smoothly move the cardboard 10 by constantly adhering the cardboard 10, and can adjust the pressure applied in consideration of the moving speed of the cardboard 10. have. If the pressure roller 31 has a rotation means, it is possible to control the moving speed of the cardboard 10 by adjusting the rotational speed of itself. That is, when the rotational speed of the pressure roller 31 is high, the moving speed of the cardboard 10 is increased, and the moving speed of the cardboard 10 may be slowed by slowing the rotating speed. On the other hand, the length of the guide portion 33 can be appropriately designed in consideration of the continuity of the process of cutting and full coating, and the conveying speed of the cardboard (10). By doing so, it is possible to prevent the process from accumulating in the continuous feeder 30 of the present invention. This cutting, continuous transfer and full-line can be controlled through a separate controller.

The packaging container continuous manufacturing apparatus according to an embodiment of the present invention can significantly reduce the time to manufacture a packaging container compared to the conventional manufacturing apparatus for supplying by moving the cardboard cut by hand with a full baler. That is, the manufacturing apparatus of the present invention can continuously produce corrugated cardboard without manual work. In addition, the corrugated cardboard can be fed to the full sprayer without additional alignment by restricting the corrugated cardboard by the guide portion before being supplied to the full sprayer. On the other hand, if the cardboard is transported and supplied by hand, the cardboard may be damaged by carelessness of the operator. However, according to the apparatus of the present invention, by controlling the conveying speed of the cardboard with a pressure roller, by limiting the space to be transferred to the guide portion, it is possible to reduce the damage of the cardboard to the maximum.

As mentioned above, although the present invention has been described in detail with reference to preferred embodiments, the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is possible.
