Description

{Container blow molding automation system and molding method}

The present invention relates to a device for manufacturing containers using blow and automatic replacement of blow molds. More specifically, when manufacturing synthetic resin containers or PET containers by blow, everything from the preform, which is the basic molding product of the container, to blow molding can be performed automatically. At the same time, it relates to a container blow molding automation system and molding method with artificial intelligence (AI) function so that the mold suitable for the container specifications can be automatically replaced when the blow mold (mold) is replaced.

In general, a blow molding device heats a preform, stretches it using a stretching rod, and blows compressed air to form a hollow container.

For example, a stretch blow molding device is known as a device for manufacturing hollow containers made of synthetic resin, such as plastic containers. This stretch blow molding device generally molds preforms, which are basic products. In order to blow mold this preform using air, a blow mold is formed using a rotating table while the neck of the preform is supported. The hollow container is blow molded by stretching the preform within the blow mold using a stretching rod and sending high-pressure air into the preform through a blow core mold that blocks the entrance. Accordingly, a hollow container of a desired shape can be formed.

The blow molding device as described above has the inconvenience that only some processes are automated and the remaining parts must be manually managed by humans.

In other words, after molding the preform, which is a basic molding product, it is done manually to move it to the blow molding line. Additionally, to blow mold a small container after blow molding a wide-mouth container, a blow mold (mold) is used. There is a problem in that replacement time is delayed because each product has to be replaced manually, which reduces productivity.

Looking at the prior art in this field, the container manufacturing device of Patent Registration No. 10-1585152 (registration date January 7, 2016) uses a resin material to form a container, as shown in Figure 1. ) a preform molding module that forms the shape of; an injection module connected to the preform molding module to supply resin material to the preform molding module; a container molding module including a container mold that injects air into the preform completed in the preform molding module to expand the preform to form the shape of the container; It includes a rotation table on which a lip plate on which the preform or container is mounted while rotating between the preform molding module and the container molding module, wherein the preform or container is placed upside down on the lip plate and is positioned on the top of the lip plate. By being supported to be disposed in an extended form, the lip plate is disposed below the preform or container, the inlet of the preform or container disposed on the lip plate is disposed to look downward, and the upper part of the rotary table The lip plate is detachably seated and supported, and the lip plate is moved by the operation of the preform molding module or the container molding module with respect to the rotary table during the work stage process by the preform molding module or the container molding module. A container manufacturing apparatus that can be removed from the rotary table and move up or down or remain seated on the rotary table has been disclosed.

The prior art of FIG. 1 includes a preform molding module that forms the shape of a pre-form of a container using a resin material; a container molding module including a container mold that injects air into the preform completed in the preform molding module to expand the preform to form the shape of the container; It includes a rotation table on which a lip plate on which the preform or container is mounted while rotating between the preform molding module and the container molding module, and is provided adjacent to the container molding module to form a cavity corresponding to the shape of the container. It is characterized by further including a label supply module that supplies labels before preform expansion inside the mold.

That is, in the prior art of Figure 1, the container is formed by forming a container preform and blow molding the container by injecting air while stretching the preform, but a label supply module that supplies the label before the preform expands inside the mold where the cavity is formed is used to supply the label. It is being formed.

This prior art consists of preforming the container in a blow molding machine → label forming → blow molding → unloading the molded container. When replacing the blow molding mold or preform mold, it must be replaced manually, which delays work time and increases safety. There are problems with the risk of accidents and low productivity.

In particular, recently, the Serious Accident Punishment Act has been newly established, and if a safety accident occurs at an industrial site, the CEO of the company will be subject to legal punishment. As the risk of safety accidents is very high when replacing heavy blow molds, an alternative to solve this problem is required.

An automated system for blow molding of containers, characterized in that it includes an automatic control device to control each of the driving units. According to paragraph 1,
The preform delivery robot is an automated blow molding system for containers, characterized in that it combines a delivery jig in which a plurality of preforms molded in the preform injection unit are combined and then supplies the preform to the preform alignment unit along the delivery guide rail. According to paragraph 1,
An automated system for blow molding of containers, characterized in that the rotary exchange mold part is provided with a rotating member sequentially rotated by a driving unit installed at the bottom, and an exchange mold disposed radially on the rotating member. According to paragraph 1,
The gantry loader is installed to be connected to the top of a first support installed on one side of the rotary exchange mold part and a second support formed on one side of the blow molding part, and a mold transfer lift is installed to be guided by the gantry loader and move back and forth. , The mold transfer lift is a container blow molding automation system, characterized in that a mold jig robot is installed at the bottom of the lift boom to move the mold from the rotary exchange mold section to the blow molding mode section. According to paragraph 1,
The automatic control device is connected to wireless or wired Internet and can be remotely controlled by mobile or computer. The blow molding process of the container is,
After the PET raw material in the hopper is melted in the preform injection unit according to a signal from an automatic control device, injection molding a preform, which is the basic product of the container, using a preform mold;
A step of removing the preform injected from the preform injection unit from the preform mold and cooling it with an air cooler while it is inserted into the discharging jig at the bottom of the preform discharging robot;
Elevating the preform delivery robot connected to the delivery jig in which the preform is inserted and transferring it to the preform alignment unit along the delivery guide rail;
Transferring and preheating the preform transferred to the preform alignment unit along a guide rail and then seating it at the mold entrance of the blow molding mold unit;
forming a container by blowing while stretching the preform seated in the blow molding mold;
Transferring the molded container to a packaging box prepared in the container discharging unit through a container discharging and transporting device;
Holding and lifting the exchange mold of the rotary exchange mold part installed on one side of the container carrying unit with a mold transfer lift;
A blow molding method for a container, characterized by the step of holding the replacement mold and transporting the raised mold transfer lift along a gantry loader to exchange the used mold of the blow molding mold portion.
