Hereinafter, with reference to the accompanying drawings will be described in detail a paper container manufacturing apparatus with a resin layer is proposed as a preferred embodiment in the present invention, and a paper container manufacturing method using the resin layer using the same.

Figure 1 shows the overall configuration of the paper cup manufacturing apparatus proposed as a preferred embodiment in the present invention, Figure 2 and Figure 3 and the overall configuration of the outer member molded part for paper cup manufacturing apparatus proposed in a preferred embodiment of the present invention; , And sequentially showing the forming process of the outer member through the outer member forming portion, Figure 4 and Figure 5 is a paper cup manufacturing apparatus proposed in the preferred embodiment in the present invention, the overall configuration of the post-processing portion, and through the post-processing portion It shows the post-processing process of prefabricated paper containers.

The paper container manufacturing apparatus 1 having a resin layer according to the present invention includes a bottom member molding part 10 for cutting the battery 121 having the resin layer formed thereon and forming the bottom member 120 as shown in FIG. 1. ; An outer member forming part 20 which overlaps both ends of the paper plate 111 on which the resin layer is formed, and then melt-bonds the overlapping parts to form the tubular outer member 110; Provisional assembly 30 for pre-assembled by entering the bottom member 120 formed through the bottom member forming portion 10, the inner diameter of the outer member 110 formed through the outer member forming portion 20; And a post-processing portion 40 which performs preheating, lower curling, bonding, and upper curling of the prefabricated paper container in order to complete the paper container.

Here, the bottom piece forming portion 10 generally includes a cutting table 11 having a cutting hole 11a formed therein; Lifting the cutting hole (11a) of the cutting table 11 in communication with the upper and lower, and the exit rod 12 for cutting the circular bottom member 120 from the battery 121 disposed in the lower portion of the cutting hole (11a) It is configured to include.

And, as shown in Figure 1, the outer member forming part 20 discharges the sheet of paper 111 loaded on the mounting table 21 sheet by sheet, bent in a tubular shape along the surface of the mold 23 to overlap both ends. After forming the tubular outer member 110 by joining both ends of the overlapping paper plate 111, the outer member 110 is designed to supply to the temporary assembly hole 31 of the temporary assembly part 30. .

According to the present embodiment, the outer member forming part 20 includes: a mounting table 21 forming a loading space of the paper plate 111 as shown in FIGS. 2 and 3; A conveying member 22 disposed on the lower portion of the mounting table 21 and left and right reciprocated while adhering the paper plates 111 mounted on the mounting table 21 one by one to discharge in one direction; The pair of clamping arms 24 overlapping both ends of the paper plate 111 with the upper part of the mold 23 by bringing the paper plate 111 discharged by the transfer member 22 into close contact with the outer edge of the mold 23. ; And a joining member 25 formed at an upper portion of the mold to bond both ends of the paper plate 111 overlapped by the pinching arms 24 to form the tubular outer member 110.

Referring to the drawings, the PET coating layer 111a is formed on the surface of the paper plate 111 constituting the outer member 110, and the clamping arm 24 disposed on both left and right sides of the mold 23 is the lifting rod 24a. Is connected to the link structure and configured to pivot inward or outward by the lifting action of the lifting rod.

Therefore, when the sheet of paper sheet 111 loaded on the mounting table 21 by the conveying member 22 moves to the lower part of the mold 23, the pinching arm 24 pivots inward so that the paper plate 111 is moved. The surface of the mold 23 is wrapped, and in this state, the bonding member 25 melts and joins both ends of the overlapped paper plate 111 to form the tubular outer member 110.

Then, the outer member 110 formed through this process is inserted into the temporary assembly hole 31 of the temporary assembly unit 30 by the transfer action through the transfer member 22, the temporary assembly hole of the temporary assembly unit 30 ( 31 is inserted into the outer member 110, the bottom member 120 is cut and molded from the bottom member forming portion 10 enters and is assembled, such a bottom piece forming portion, the outer member forming portion, and the overall assembly The composition and action are similar to those known.

However, in the present embodiment, by improving the outer member forming part 20 for molding and supplying the outer member 110 to the provisional assembly 30, the outer member 110 through rapid bonding of both ends of the paper piece 111. The stable forming and the paper plate 111 is configured to be adsorbed to the mold 23 during the molding process of the outer member 110, thereby ensuring the productivity and quality stability according to the production of the outer member 120.

In this embodiment, the PET resin layer 111a formed on the surface of the overlapping paper plate 11 by means of bonding means at both ends of the paper plate 11 superimposed by the sandwich arm 24 is formed on the surface thereof. The ultrasonic bonding member 25 which melt | dissolves in a short time and mutually bonds the both ends of the paper plate 111 is employ | adopted.

In addition, a plurality of intake holes 23a communicating with a vacuum pump (not shown) are formed on the outer wall of the mold 23, and surrounded by the pair of clamping arms 24 around the mold 23. The paper sheet 111 is sucked and fixed by the intake pressure provided from the plurality of intake holes 23a.

When the both ends of the overlapping paper plate 111 is bonded by adopting the ultrasonic bonding member 25 as in the present embodiment, the both ends of the paper plate are directly connected to both ends of the overlapping paper plate by conventionally heating the heater type bonding member. Productivity is improved compared to the joining form to join, and formation of a more stable joining state is possible.

In particular, as the heater type bonding member, the PET resin layer 111a, which is difficult to bond, can be stably melted and bonded in a short time, and the paper sheet adheres to the surface of the mold 23 by the intake pressure by the intake air as described above. When the joining is made in a closed state, the outer member 110 can have a stable dimensional accuracy, so that the outer diameter of the bottom member 120 and the inner diameter of the outer member 110 are inconsistent with each other, resulting in poor joining. Problems made can be solved.

Then, the outer member 110 formed through this process is inserted into the temporary assembly hole of the temporary assembly by the transfer action (transfer action through), the outer member inserted into the temporary assembly hole of the temporary assembly part is cut and molded in the bottom member molding part The bottom member is entered to form a container member in a pre-assembled state, and then the outer member and the bottom member in the pre-assembled state are molded by a paper container having a sealing property by the post-processing part.

On the other hand, the post-processing portion as shown in Figures 1 and 4 to 6 and the base 41, the preheating section (A, A '), the lower curling section (B) and the junction section (C) is arranged concentrically; It is configured to include a rotating body 42 is disposed spaced apart on the upper portion of the base 41 in an equal rotation in one direction.

Referring to the drawings, the rotating body 42, the adsorption blocks 42a for adsorbing and moving the paper containers for each section according to the isotropic rotation of the rotating body 42 are arranged in a concentric structure, pre-assembled in the temporary assembly unit 30 The drawn paper containers are adsorbed by the isotropically rotating adsorption block 42a, and the preheating sections A and A ', the lower curling section B, the joining section C, and the upper curling section D formed on the base 41 are carried out. It is molded into a paper container while moving sequentially.

Here, the adsorption block 42a disposed concentrically on the rotating body 42 in the post-processing part 40 can be lowered by pressurization of a lifting rod (not shown), thereby adsorbing and seating the prefabricated paper container. For the sake of simplicity, reference to the detailed description and drawings will be omitted for the convenience of description.

However, the post-processing part 40 of the paper container manufacturing apparatus is a paper container pre-assembled through the isometric rotation of the rotating body 42 to perform the post-process continuously, the turntable structure adopted in the present embodiment is narrow in nature Although there is an advantage that the continuous execution of different processes in the space, but the longer the time to perform any one process in comparison with the other process has the disadvantage that the overall process is delayed and the efficiency of the work is reduced.

In detail, the post-processing portion 40 of the paper container manufacturing apparatus according to the present embodiment, the resin layer is heated and softened, and the resin layer adopts a PET resin layer having a relatively higher melting point than PE and PP. As such, stable preheating through continuous heating is required.

However, when the preheating time for heating and softening the PET resin layers 111a and 120a formed on the outer member and the bottom member is relatively long, the lower curling process (B) and the bonding process requiring a relatively short process time than the preheating process are required. Since (C) and the upper curing process (D) are delayed as a whole, as a result, the cycle timing according to the post-processing of the pre-assembled paper container becomes long overall.

However, if the temperature of the heat transfer heater is set to 300 ° C. or more higher than an appropriate temperature to facilitate rapid heating of the outer member 110 and the bottom member 120, the physical properties of the PET resin layer formed on the surface of the prefabricated paper container are changed. In addition, since the lower part of the prefabricated paper container is not heated entirely and only a part of the PET resin layer of the prefabricated paper container is heated, it is difficult to form a continuous heating state thereof.

In consideration of this, in the present embodiment, the preheating sections A and A 'are separated into a first preheating furnace 41A and a second preheating furnace 41A', and the adsorption block 42a of the rotating body 42 is formed. The paper container in the temporarily assembled state, which is adsorbed on and sequentially turned, is allowed to sequentially enter and heat the first preheating furnace 41A and the second preheating furnace 41A '.

That is, in the present embodiment, the preheating section is not implemented through one preheating furnace, and is separated into the first preheating furnace 41A and the second preheating furnace 41A ', thereby ensuring sufficient time for heating and subsequent It is to solve the problem that the lower curry process (B) and the bonding process (C) and the upper curry process (D) which proceeds to the delay.

In the first preheating furnace 41A and the second preheating furnace 41A 'forming the preheating section A-A', a heat transfer heater 41A-a is built in to heat the lower portion of the paper container in the preassembled state. In general, the temperature is maintained at 200 ° C to 250 ° C.

Thus, the prefabricated paper container is preheated first in the first preheating furnace 41A in a state of being adsorbed by the adsorption block 42a installed on the rotor 42 as shown in FIG. 5A, and the first preheating is carried out. The paper container of the pre-assembled state, the lower part of which is preheated, is adsorbed through the adsorption block 42a installed on the rotating body 42 and then to the lower curling mold B constituting the lower curling section B as shown in FIG. 5B. Entering and descending, and through this process, the lower edge of the exterior member 110 is cured inward to surround the edge of the bottom member 120 protruding downward.

At this time, since the lower edge of the exterior member is sufficiently preheated through the aforementioned preheating section, physical damage does not occur during the curing process.

Subsequently, as shown in FIG. 5C, the lower part of the second preheating furnace 41A ′ is preheated secondarily to stably soften the PET resin layers 111a and 120a through the stable preheating of the lower part of the preassembled paper container. The edge of the bottom member 120 protruding downward, and the lower edge of the outer member 110 surrounding the bottom member 120 are bonded to each other through the softened PET resin layer while passing through the bonding section C.

Here, the bonding section (C) is basically a bonding mold 41C having a seating groove for seating the lower part of the preassembled paper member, and rotating in one direction along the lower inner wall of the paper container seated on the bonding mold 41C. By physically pressing the lower edge of the outer member 110 and the edge of the bottom member 120 superimposed through the lower curling process (B), to promote their adhesion through the softened PET resin layer (111a, 120a) It is comprised including the rotating piece 41C-a.

By the way, the rotating piece 41C-a is relatively lower than the temperature of the paper container heated through the preheating sections A and A ', so that when the rotating piece contacts the paper container in the bonding process, it is formed on the surface of the paper container. As the PET resin layer is quenched, it is difficult to bond the outer member and the bottom member through the PET resin layer.

In view of this, in the present invention, the heat transfer heater 41C-b for heating the rotating piece 41C-a is added to the bonding mold 41C, and the superimposed outer member 110 and the bottom member 120 are attached. The rotary member 41C-a, which is pressurized and joined, is configured to form a heated state by receiving the heat provided through the heat transfer heater 41C-b, thereby forming the outer member in which the rotary piece 41C-a overlaps. Even if it is in contact with the 110 and the bottom member 120 is formed in the outer member 110 and the bottom member 120 so that the softened PET resin layer (111a, 120a) is not quenched to form a stable bonding state.

Thereafter, the paper container in which the bonding is completed, the upper edge is pressed by the upper curry mold 41D which descends in the state seated on the support mold 41D-a of the upper curry section A, and the upper curry is achieved. .

Thus, the paper container manufacturing apparatus 1 according to the present embodiment, while sequential preheating by the first preheating furnace 41A and the second preheating furnace 41A ', stably preserves the preheating temperature and preheating time, and subsequently Since the process does not delay in proceeding the lower curing process (B), the bonding process (C) and the upper curing process (D), the cycle timing according to the production of paper containers with a longer preheating time than other processes This overall longer problem is solved and thus improved productivity can be achieved.

On the other hand, the manufacturing method through the paper container manufacturing apparatus configured as described above, the transfer member 22 of the outer member forming portion 20 as shown in Figure 3a adhered to the paper plate 111 stacked on the mounting table (22) When the transfer to the mold 23 is carried out, as shown in FIG. 3B, the clamping arm 24 pivots inward to surround the paper plate 111 on the surface of the mold 23 so as to overlap both ends of the paper plate 111.

In this state, the bonding member 125 irradiates and presses ultrasonic waves to both ends of the overlapped paper plate 111, softens the PET resin layer 111a formed on the surface of the paper plate 111, and joins through pressure to form a tubular shape. The outer member 110 is molded, and the transfer member 22 transfers the molded outer member 110 to enter the temporary assembly hole 31 of the temporary assembly part 30.

At the same time, the bottom member forming part 10 is the bottom member 120 in the battery 121 while the exit rod 12 raises the cutting hole 11a of the cutting table 11 in which the battery 121 is located at the bottom. After cutting, the bottom member 120 enters the outer member 110 that enters the temporary assembly hole 31 of the temporary assembly part 30 to temporarily assemble the bottom member 120 to the outer member 110.

Next, the adsorption block 42a of the post-processing portion 40 sucks the container member in which the outer member 110 and the bottom member 120 are assembled in the temporary assembly portion 30 and pivots at an angle to the base 41. The preheating sections A and A 'formed in FIG. 1, that is, primary preheating through the first preheating passage 41A are preheated to preheat the lower part of the prefabricated container member.

Thereafter, the adsorption block 42a adsorbs the container member in the preassembled state preheated in the preheating section and enters the lower curling mold 41B of the lower curling section B, as shown in FIG. 5B, so that the lower edge of the exterior member 110 is closed. Curing inward to wrap around the edge of the bottom member 120 protruding downward.

Then, the container member in the pre-assembled state that the lower curing is completed as shown in FIG. 5C is inserted into the second preheating furnace 41A ', and the second adsorption preheating is performed as shown in FIG. 5D. When adsorbed and entered into the joining mold 41c of the joining section, the rotary piece 42C-a preheated by the heat transfer heater 42C-b has a lower portion of the outer member 110 superimposed through the lower curing process (B). The edge and the edge of the bottom member 120 are physically pressed to bond them between the softened PET resin layers 111a and 120a.

Next, as shown in FIG. 5E, the upper currying mold 41D presses the upper edge of the paper container on which the bonding of the lower portion is completed to curry the upper portion of the container member, thereby being cured at the lower edge of the outer member 110. The member 120 is bonded, the upper part of the outer member 110 is curled to the outside, and the molding of the paper container 1 in which the PET resin layer is formed on the surface is completed.
