Hereinafter, with reference to the accompanying drawings will be described in detail the outer member molding machine for paper cup manufacturing apparatus proposed as a preferred embodiment in the present invention.

Figure 1 shows the overall configuration of the paper cup manufacturing apparatus having an outer member molding machine proposed as a preferred embodiment in the present invention, Figure 2 is a whole of the outer member molding machine for paper cup manufacturing apparatus proposed as a preferred embodiment in the present invention 3 is a view showing the forming process of the outer member through the outer member forming part shown in FIG. 2 in sequence, Figure 4 is produced through the outer member forming machine proposed as a preferred embodiment in the present invention It shows the outer member.

The outer sheet molding machine 100 for a paper cup manufacturing apparatus proposed as a preferred embodiment in the present invention, a paper cup manufacturing apparatus 1 including a bottom piece molding machine 200 and a cup molding machine 300 as shown in FIG. Installed in the stack 110 to discharge the sheet of paper 10 sheet by sheet, bent in a cylindrical shape along the surface of the mold 130 to overlap both ends (11, 11 '), this overlapping paper plate Both ends 11 and 11 'of (10) are designed to form a tubular outer member 10' and to be supplied to the bottom piece molding machine 200.

Here, the bottom piece molding machine 200 generally includes: a mounting table 210 for inserting the outer member 10 ′ discharged through the outer member molding machine 100 into the fixing hole 211 to rotate isometrically; A cutting table 220 disposed at a lower portion of the mounting table 210 to conformally rotate and have a cutting hole 221 sequentially communicating with the fixing hole 211 of the mounting table 210 in the body; And elevating the cut holes 221 of the cutting table 220 and the fixing holes 211 of the mounting table 210 to communicate with each other up and down, and the bottom of the circle in the battery 20 disposed below the cutting holes 221. It is configured to include an exit rod 230 for taking out the plate 20 'and inserting it into the inner diameter of the outer member 10'.

In addition, the cup molding machine 300 is rotated at an angle and inserts the outer member 10 'into which the bottom piece 20' is inserted into the forming groove 311 of the forming table 310 in which the heater is installed. (Not shown) is configured to insert the edge of the bottom piece 20 'into the inner diameter of the outer member 10' to form the paper cup 30, these bottom piece forming machine 200 and the cup forming machine 300 ) Is similar to the known one.

However, in the present embodiment, by improving the outer member forming part 100 for molding and supplying the outer member 10 'to the bottom piece molding machine 200, the end of the paper piece 10, both ends 11, 11' In order to improve the productivity and quality of the outer member (10 ') through the bonding, in particular, the paper plate 10 is configured to be bonded in a stable state to the mold 130 to ensure improved working stability. .

According to the present embodiment, the outer member forming part 100 includes: a mounting table 110 forming a loading space of the paper plate 10 as shown in FIGS. 2 to 3; A transfer member 120 disposed on the lower side of the mounting table 110 and left and right reciprocated while adhering the paper plates 10 mounted on the mounting table 110 one by one to discharge in one direction; A pair of the paper plate 10 discharged by the transfer member 120 in close contact with the outside of the mold 130 to overlap both ends (11, 11 ') of the paper plate 10 to the upper portion of the mold 130 Stenosis cancer 140; And a joining member disposed on the mold 130 to bond both ends 11 and 11 'of the paper plate 10 overlapped by the pinching arms 140 to form a tubular outer member 10'. And 150.

Then, the clamping arm 140 disposed symmetrically on both sides of the mold 130 is connected to the lifting rod and the link 141 to pivot inward or outward by the forward and backward driving of the lifting rod.

In this embodiment, as shown in FIG. 4, the PET coating layer 12 is formed on the surface of the paper plate 10 constituting the outer member 10 ′.

In addition, as a means for forming the tubular outer member 10 'by joining both ends 11 and 11' of the paper plate 10 overlapped by the holding member 140, the overlapping paper plate 10 Ultrasonic bonding members 150 are applied to both ends 11 and 11 'of the paper plate 10 by melting the PET coating layer 12 formed on their surfaces by emitting ultrasonic waves at both ends.

When both ends of the paper plate 10 are bonded through the ultrasonic bonding member 150, the conventionally heated heater-type bonding member is directly connected to both ends of the overlapping paper plate to prepare for the bonding form for bonding both ends of the paper plate. Productivity is improved, while more stable bonding can be formed.

In addition, in the present exemplary embodiment, a plurality of intake holes 131 communicating with the vacuum pump 132 are formed on the outer wall of the mold 130 in a radial structure, and the mold is formed by the pair of clamping arms 140. The plurality of intake holes 131 provide the intake pressure to the paper plate 10 wrapped around the outer side of the 130, so that the paper plate 10 formed on the outer side of the mold 130 closely adheres to the surface of the mold 130. In this state, both ends 11 and 11 'are quickly joined by the ultrasonic bonding member 150.

When the bonding is performed in a state where the paper plate 10 is in close contact with the surface of the mold 130 by the intake pressure by the intake holes 131 as described above, the outer member 10 'may have stable dimensional accuracy. Since the outer diameter of the bottom piece 20 and the inner diameter of the outer member 10 'are inconsistent with each other, the problem of poor bonding can be solved.

And, in the manufacturing process of the paper cup through the outer member forming machine 1 configured as described above, as shown in Figure 3a, the transfer member 120 affixed to the paper plate 10 loaded on the bottom of the mounting table 110 Adhesion through the 122 to transfer the lower portion of the mold (130).

Thereafter, the pinching arm 140 pivots inward as shown in FIG. 3B so that the paper plate 10 positioned at the lower portion of the mold 130 surrounds the outside of the mold 130. Both ends 11 and 11 'form an overlapping state at the top of the mold 130.

In this state, as shown in FIG. 3C, the plurality of intake holes 131 formed on the surface of the mold 130 are wrapped in the outer portion of the mold 130 by the sandwich arm 140 pivoting inwardly. By providing an intake pressure to the surface of the mold 130, the paper plate 10 is in close contact with and fixed.

Thereafter, the ultrasonic bonding member 150 disposed on the upper portion of the mold 130 descends as shown in FIG. 3d and emits ultrasonic waves in a state in which both ends 11 and 11 'of the overlapping paper plate 10 are pressed. By melting the PET coating layer 12 formed on both ends 11 and 11 'of 10, the tubular outer member 10' to which both ends 11 and 11 'of the paper plate 10 are joined is formed. .

When the molding of the outer member 10 'is completed through this process, the supply of the intake pressure by the intake hole 131 is stopped to release the adsorption state of the outer member 10' and the mold 130, and the transfer member 120 moves the molded outer member 10 ′ in one piece to enter the fixing hole 211 of the bottom piece molding machine 200.

Subsequently, a disk-shaped bottom piece 20 'is inserted into the inner diameter of the outer member 10' by the bottom piece molding machine 200, and then the outer member 10 'into which the bottom piece 20' is inserted is The heater is supplied to the shaping groove 311 of the built-in cup molding machine 300 to finally form the paper cup 30 in which the edge of the bottom piece 20 'is melted and bonded to the tubular outer member 10'. .

Figure 1 shows the overall configuration of the paper cup manufacturing apparatus having an outer member molding machine proposed as a preferred embodiment in the present invention,
