Description

[Technical field]

[0001] The present invention relates to a blow mould transport system and method for transporting moulds used in blow moulding bottles from preforms. [Background technology]

[0002] Beverage products are widely sold which are obtained by supplying a preform obtained by injection molding a plastic, heating the supplied preform to a moldable temperature, blow-molding the heated preform into a bottle, filling the molded bottle with a beverage, and sealing the bottle filled with the beverage. Such products are produced by a filling machine for filling a beverage, which includes a heating device for heating the preform, a blow-molding device for molding the heated preform into a bottle, a filling device for filling the molded bottle with the beverage, and a sealing device for sealing the bottle filled with the beverage. Sterilized beverage products produced by an aseptic filling machine which includes a sterilization device for sterilizing the preform and / or the bottle and fills the sterilized beverage are also widely sold.

[0003] Beverage products are manufactured in bottles of various shapes depending on the type and volume of the beverage to be filled. When changing the type of beverage, the type of beverage to be supplied is changed, and when changing the volume of the beverage to be filled, the filling amount of the filling device is changed. When changing the type of beverage, there is no need to change the filling device of the filling machine. However, when changing the volume or the shape of the bottle, the mold that gives the shape of the bottle must be replaced.

[0004] A blow molding machine has many blow molding stations, and changing the molds at all the blow molding stations is a time-consuming task for workers. In addition, a mold for one type of shape is made up of many molds, and the same number of mold sets as the number of blow molding stations must be stored. Various proposals have been made for storing many molds for one bottle shape, transporting the stored molds, and shortening the time it takes to change molds when changing bottle shapes.

[0005] A mold exchange device has been proposed that moves a cart on which a mold is placed on a conveyor rail to a molding machine to perform efficient mold exchange (Patent Document 1). A mold storage system has been proposed that is composed of a cart equipped with a driveable stacker crane and a mold push-pull device for storing molds in a mold storage slide rack arranged three-dimensionally (Patent Document 2). Furthermore, it has also been proposed to significantly shorten the mold exchange work time by storing molds in a rotating mold holding device, moving this mold holding device near a blow molding device, storing the mold to be removed from the blow molding station in the mold holding device while rotating the mold holding device, and attaching a new mold stored in the mold holding device to the blow molding station (Patent Document 3, Patent Document 4).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The present invention provides a system and method for transporting a blow molding die to be incorporated in a blow molding machine that blow molds bottles in a filling machine that supplies preforms, blow molds the supplied preforms into bottles, and fills the molded bottles with beverages. Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0022] 1 shows a blow molding die 3 being transported, a preform 1 before being molded by the blow molding die 3, and a bottle 2 to be molded in a blow molding die transportation system according to an embodiment of the present invention. The lower end of the mouth of the preform 1 is sandwiched between the blow molding die 3, and compressed air is blown into the inside of the preform 1 to mold the preform 1 into a bottle 2 having the shape of the blow molding die.

[0023] The preform 1 is a test tube-like cylindrical body with a bottom, and is provided with a mouth 1a similar to that of the bottle 2 at the beginning of molding. A male thread is formed in this mouth 1a at the same time as molding the preform 1. In addition, a support ring 1b for transportation is formed below the mouth 1a of the preform 1. The preform 1 or the bottle 2 is held by a gripper via this support ring 1b, and travels inside a filling machine that fills it with a beverage. The filling machine that fills it with a beverage is provided with a transport path for transporting the preform 1 and the bottle 2.

[0024] The preform 1 is molded by injection molding, compression molding, or the like. The material of the preform 1 is made of a thermoplastic resin such as polyethylene terephthalate, polyethylene naphthalate, polypropylene, or polyethylene, and may be a single resin or a mixture of these resins, or may contain recycled thermoplastic resin. In order to impart barrier properties, the preform 1 may contain a thermoplastic resin such as an ethylene-vinyl alcohol copolymer or a polyamide having an aromatic amine such as metaxylylenediamine as a monomer, as a layer or as a mixture.

[0025] The preforms 1 are continuously fed from a preform feeder 4 shown in FIG. 3 to a preform heating device 6 by a preform feed conveyor 5 at a desired speed.

[0026] The preform 1 supplied to the preform heating device 6 is transported by a wheel 7 equipped with many grippers at a fixed pitch, and reaches a heating device transport wheel 8. Here, the preform 1 is released from the grippers, and a spindle is inserted into the mouth portion 1a of the preform 1, and the preform 1 is transported. In the preform heating device 6, the preform 1 is heated by an infrared heater 9 or other heating means to a temperature suitable for subsequent blow molding. This temperature is preferably 90°C to 130°C. The temperature of the mouth portion 1a of the preform 1 is kept below 70°C to prevent deformation, etc.

[0027] A spindle is inserted into the mouth 1a of the preform 1, and the preform 1 is heated by an infrared heater 9 and transported by an endless chain 10 while rotating. The spindles are provided at regular intervals on the endless chain 10. The endless chain 10 rotates by a pulley. By inserting a mandrel into the preform 1 instead of the spindle, it is also possible to transport the preform 1 while rotating it in an inverted state.

[0028] The heated preform 1 is released from the spindle, gripped by a gripper, and transported via a wheel 11 to a molding wheel 13 of a blow molding machine 12. A number of blow molding stations 14 are provided around the molding wheel 13, and the preform 1 is blow-molded into a bottle 2 by a blow molding die 3 installed in the blow molding stations 14. The blow molding die 3 and a blow nozzle that blows air into the preform 1 are disposed in the blow molding stations 14. The blow molding stations 14 revolve at a constant speed together with the rotation of the blow molding wheel 13.

[0029] When the heated preform 1 arrives, the blow molding die 3 installed in the blow molding station 14 clamps the preform 1. Then, a blow nozzle is joined to the preform 1, and a stretching rod is guided to a hole in the blow nozzle and inserted into the preform 1. The inserted stretching rod stretches the bottom of the preform 1, thereby vertically stretching the preform 1, and at the same time, air is blown into the preform 1 from the blow nozzle, thereby horizontally stretching it. The preform 1 is vertically and horizontally stretched in the blow molding die 3, and a bottle 2 is molded. The molded bottle 2 is removed from the blow molding die 3, the support ring 1b is gripped by a gripper installed on a wheel 15, and the bottle is transported to the next process.

[0030] The blow molding station 14 provided in the blow molding machine 12 is usually as many as 10 to 32, and the blow molding molds 3 to be incorporated in the blow molding station 14 are required as a set of the same number as the blow molding stations 14. As shown in FIG. 1(A), the blow molding mold 3 is composed of a neck mold 3a for molding the neck of the bottle 2, a body mold 3b for molding the body, and a bottom mold 3c for molding the bottom. The neck mold 3a and the body mold 3b are split molds and form a pair. It is also possible to mold the neck using the body mold 3b without providing the neck mold 3a. The blow molding molds 3 are required as many as the blow molding stations 14, and the number of blow molding molds 3 ranges from 3 to 5. These blow molding molds 3 are stored in the mold storage device 16 as a set. A set of 3 to 5 blow molding molds 3 is 10 to 32 times the number of molds of the blow molding stations 14.

[0031] The blow molding die 3 stored in the die storage tool 16 may be stored in a disassembled state in which the blow molding die 3 for molding each part is disassembled, or may be stored assembled in a state in which it is to be incorporated into the blow molding station 14. In addition to the blow molding die 3, parts that are used simultaneously with the blow molding die 3, such as a stretching rod and a blow nozzle, may be stored together.

[0032] The mold storage tool 16 is rectangular or circular, and includes a mold holder for storing the blow mold 3. The mold holder may be a shelf for placing the blow mold 3, a shelf with a hole for inserting and holding the assembled blow mold 3, or the like, and may be of any shape as long as it can hold the blow mold 3. It is convenient for the mold replacement work if the shelf is made slidable. In addition, by making the shelf of the circular mold storage tool 16 rotatable, the mold replacement work can be performed efficiently. By performing the mold replacement while rotating, the blow mold 3 can be inserted and removed without moving the mold storage tool 16. A drive device may be provided for rotation.

[0033] It is preferable that the mold storage tool 16 shields the portion that stores the blow molding mold 3. The side of the mold storage tool 16 is shielded by an openable / closable plate-like member or an openable / closable curtain-like member. The top and bottom surfaces of the mold storage tool 16 are also shielded by plate-like members. It is preferable that at least a part of the four corners of the bottom surface of the mold storage tool 16 be made convex so that the tines of a forklift can be inserted into the bottom surface of the mold storage tool 16 for transportation.

[0034] The mold storage tool 16 is stored in an automatic warehouse 17. It is preferable that the automatic warehouse 17 supplies air from above that has been filtered to remove dust.

[0035] As shown in Fig. 5, the automated warehouse 17 is provided with multiple rows and levels of shelves 18 for storing the mold storage devices 16. The automated warehouse 17 is provided with an automated warehouse transport device 19 for placing the mold storage devices 16 on the shelves 18 and transporting them. As shown in Fig. 6, the automated warehouse transport device 19 travels between the shelves 18 provided on both sides, and transports the mold storage devices 16 to the shelves 18 provided on both sides of the traveling direction in parallel to the traveling direction of the automated warehouse transport device 19. The automated warehouse transport device 19 can also rise and fall to transport the mold storage devices 16 to the multiple shelves 18. The shelves may be provided only on one side of the automated warehouse transport device 19.

[0036] The automated warehouse transport device 19 transports the mold storage device 16 to a predetermined location on the shelf 18 by the automated warehouse control device, and also takes it out as necessary. The automated warehouse transport device 19 is equipped with a device for moving the mold storage device 16, which places the mold storage device 16 or carries it in and out of the predetermined location on the shelf 18. A signal of mold information to be transported is sent to the automated warehouse transport control device from the preform supply container transport device 23 that transports the mold storage device 16 or an operation panel provided at a predetermined location, and the automated warehouse transport device 19 carries in or takes out the mold storage device 16 that stores the appropriate molds in accordance with the signal sent.

[0037] The mold storage tool 16 storing the blow molding molds 3 used in the blow molding machine 12 stored on a shelf 18 of the automated warehouse 17 is carried out. The mold storage tool 16 stored in a predetermined location on the shelf 18 is carried out by the automated warehouse transport device 19 in response to an instruction from the automated warehouse control device. The mold storage tool 16 to be carried out is placed on a cart 20. The cart 20 on which the mold storage tool 16 is placed transports the mold storage tool 16 with the mold storage tool 16 on it. The placement from the automated warehouse transport device 19 to the cart 20 or the movement from the cart 20 to the automated warehouse transport device 19 is performed by a conveyor, a rotating roll, an automatic traveling forklift, a hanging transport device, or the like provided on the automated warehouse transport device 19 and the cart 20.

The opening and closing door 21 of the blow molding machine 12 is opened, and the cart 20 is stopped adjacent to the molding wheel 13. An unmanned cart traveling device is provided for the cart 20 to travel unmanned from the automated warehouse 17 to the vicinity of the blow molding machine. The cart 20 transports the mold storage tool 16, but it may be a forklift. The unmanned forklift traveling device allows the cart to travel unmanned.

[0039] As shown in FIG. 4, the worker 22 opens the blow molding station 14 provided on the molding wheel 13, removes the blow molding die 3 that has been used from the blow molding station 14, and stores the removed blow molding die 3 in a space that has been vacated in the die storage device 16. The worker 22 takes out the blow molding die 3 to be used this time stored in the die storage device 16, and installs it in the blow molding station 14 from which the blow molding die 3 that has been used is removed. The worker 22 removes the blow molding die 3 of the next blow molding station 14, and stores the removed blow molding die in the vacant space by installing it in the blow molding station 14. This work is repeated to replace all the blow molding dies 3. In FIG. 4, the blow molding die 3 is replaced by the worker 22, but it may be replaced by a robot. When the die replacement at one of the blow molding stations 14 is completed, the molding wheel 13 is intermittently rotated by an angle obtained by dividing 360 degrees by the number of blow molding stations 14.

[0040] After all of the blow molding dies 3 have been replaced, the cart 20 travels unmanned by an unmanned traveling device from near the blow molding machine 12 to the automated warehouse 17. The die storage tool 16 transported by the cart 20 is moved to the automated warehouse transfer device 19 in the automated warehouse 17 and stored in a predetermined position on the shelf 18.
