Description

Transfer material to be transported, apparatus and method for manufacturing molding container using same {TRANSFER DEVICE, AND APPARATUS AND METHOD FOR PRODUCING MOLDED CONTAINER USING THE SAME}

The present invention relates to an apparatus for conveying an object to be transported, such as a plastic container, and an apparatus and a method for manufacturing a molding container using the same. More particularly, when manufacturing a plastic container having a molding container, in particular, an inlet, It can be transported while rotating in the direction, the object to be conveyed to the object to be transported to improve the production productivity through the production of the molding container production, and also to reduce the cost, and a molding container manufacturing apparatus and method using the same.

A molding container such as a plastic container is molded in a mold while inflating a parison, a molten preform supplied through extruding of a resin raw material, to produce a container, particularly a plastic container having an inlet.

Such a molding container is mainly produced in the form of a cylinder or a square cylinder for storing oil or liquid, and is usually provided with an inlet opening and closing with a stopper.

For example, FIGS. 1 and 2 illustrate a known molding machine 200 for forming and manufacturing molding containers such as plastic containers.

1 illustrates a molding machine for producing the container 100a in a state where the container inlet is positioned upward, and FIG. 2 illustrates a molding machine for producing the container 100b in which the container inlet is located downward.

Therefore, for clarity below, reference numeral '100a' denotes a molding container in which the container inlet is positioned upward in the molding step, and '100b' denotes a molding container in which the container inlet is positioned downward in the molding step.

Meanwhile, the molding machine 200 illustrated in FIGS. 1 and 2 commonly has an extruder 210 and a parison 110 for supplying a parison 110 by extruding a (resin) raw material in a hollow form. A mold unit 220 formed of left and right molds 222 and 224 to be molded, a carrier 230 for transferring the mold, and upper and lower punching 242 and 244 for processing scrap of a molded container. It is configured to include a scrap processing unit 240.

However, since the production is performed in a state where the container inlet is positioned upward in the molding machine 200 of FIG. 1, the carrier 250 having the blowing pin 252 for injecting air into the container formed by the mold unit 220 is It is provided separately.

In addition, in the molding machine 200 of FIG. 2, the mold carrier 230 is provided with a blowing pin 232 and an expanding pin 234, and the molding container 100b having the container inlet is located at a lower portion in the mold unit. It further comprises a scrap holder unit 250 'to be transferred to the unit 240.

By the way, the manufacturing of the molding container through the known molding machine 200 had the following problems.

For example, in the case of FIG. 1, since the container is formed and manufactured in a shape in which the molding container 100a, that is, the injection port of the plastic container is positioned upward, the frame 212 and the blowing pin 252 of the extruder 210 are provided. Due to the interference of one carrier 250, the moving width (stroke) of the mold unit 220 is longer than that of the molding machine of FIG. 2, thereby increasing the size of the equipment.

In addition, in the case of the molding machine of FIG. 1, the extruder 210 for blowing air into the container through the inlet of the container should be provided with a sealing cutter 214 for precisely forming the container inlet.

Then, the left and right molds 222 and 224 of the mold unit 220 moved to the parison 110 position through the carrier 230 are closed (compressed each other), and then return to the blowing pin through the container inlet. Since 252 cools the container as it descends, the mold return is moved slowly for cooling, at least from the parison position to the blowing position, so the blowing must be performed long.

In addition, as shown in the main part in Figure 1, when the left and right molds are closed (compression each other), the upper part of the parison 100 is first contacted with the mold, the molding failure of the container inlet portion that must be precisely formed easily occurs do.

For example, unlike the molding machine of FIG. 2, the molding machine of FIG. 1 utilizes a space where the blowing pins 232 and the expanding pins 234 are to be installed (the injection hole is upward, so that the rising of the blowing pins is impossible and thus the lower parison space is used). 2), as shown in FIG. 2, the mold initial interval 'H1' of FIG. 1 is expanded while the parison 110 is expanded using the blowing pin 232 and the expanding pin 234 moving to the carrier 230. Since it is difficult to narrow down to "H2" of FIG. 2, especially in the case of container shaping | molding, a joining part will become bad.

However, in the case of Figure 1, because the container inlet is positioned upward, the finishing process such as container inspection, transfer or packaging after the mold is advantageous than the molding container (100b) located below the inlet as shown in FIG.

Therefore, compared to FIG. 1, since the container 100b injection hole is positioned downward in the case of FIG. 2, in view of the fact that the blowing pin or the expanding pin is integrated with the carrier and the lower part of the parison is opened, in particular, the parison lower part In that space can be utilized, the use of the molding machine of FIG. 2 solves the problems of using the molding machine of FIG. 1 described above.

For example, in the case of Figure 2, during the mold operation of the parison 110, the blow pin integrated into the carrier is quickly operated from the initial operation of the mold to realize the container cooling by that much, in particular, the problem that the container joint, such as Figure 1 bursting Is removed.

In particular, as shown in FIG. 1, a separate upper carrier is not required, and a space in which the carrier moves under the parison is secured, thereby reducing the overall device size.

However, in the case of FIG. 2, as described above, since the injection hole is positioned downward, a scrap holder unit 250 ′ for transferring the container from the mold unit 220 to the scrap processing unit 240 is required.

In addition, in the case of Figure 2, the molding container 100b in which the injection port is located below has a problem of making it difficult to inspect the actual container (injection or handle portion of the container where mold failure is easily generated), container transportation, and container packaging.

That is, when the container is made in a state in which the container inlet is directed downward as shown in FIG. 2, a cumbersome operation of having to rotate the container by holding the molded container by hand is necessary.

Therefore, based on the molding machine of Figure 2, when the injection port is rotated to the molding container 100b in which the injection port is located downwards automatically to the molding container 100a in which the injection port is located upwards, fully automated production of the molding container It would be preferable because it would be possible to utilize all the advantages of FIGS. 1 and 2.

Accordingly, the applicant of the present invention is used in the molding machine of Figure 2 to solve the problem occurring in the molding machine of Figure 1, the injection port is located downwards so that the injection port is automatically positioned in the molding machine of Figure 2 The present invention has been proposed to solve the problems caused.

The present invention has been proposed to solve the conventional problems as described above, the object of the aspect, in the production of a plastic container having a molding container, in particular, the injection port, by allowing the container inlet to be transported while rotating in the desired direction up or down, It is to provide a conveyed material conveying device, and a molding container manufacturing apparatus and method using the same to improve the production productivity through the full automation of the molding container manufacturing line.

The rotating shaft 72 rotates by a predetermined rotation angle, and the rotary holder arm 64 of the double structure, which is fixed to the rotating plate 71 to which the rotating shaft 72 is connected, is formed of the vertical table 42. When the horizontal drive cylinder 44 is operated, the molding container is rotated while being held.

Accordingly, as shown in FIGS. 10 and 13, the molding container 100b having the injection hole positioned downward is rotated in a state of being held by the holder arm 64 of the rotary holder unit 60 to form the injection container having the injection hole positioned upward ( The position is adjusted to 100a).

At this time, as shown in FIG. 8, the gear block 66 is fixed to the end of the holder arm 64 of the holder unit 40 as a bolt, and thus the holder when the horizontal drive cylinder 44 of the vertical stand is advanced. The holder arm 46 of the unit 40, the rotary drive means 62 of the rotary holder unit 60, and the rotary holder arm 64 connected to the rotation shaft 72 are integrally advanced to hold the molding container. Move it.

Therefore, using the holder unit arms of the present invention, it is possible to transfer up to three containers and rotate one container.
