Description

Mirror-type rotary automatic packaging machine

[0001] The present invention relates to a packaging machine, and more specifically, to a mirror-type rotary automatic packaging machine that puts various raw materials into a bag and seals the entrance of the pouch.

[0002] In order to utilize space more efficiently and improve product mass production, a rotary type automatic packaging machine has been known that sequentially performs a series of processes related to product packaging while the turntable intermittently rotates (step motion) along a set circular path, departing from the existing line-type product packaging.

[0003] Rotary type automatic packaging machines adopt a method in which packaging materials such as pouches are loaded onto the packaging machine, and a series of processes such as subsequent packaging material supply, weighing of contents to be packaged, filling of contents in containers, and sealing of container entrances are automatically performed step by step along a circular path.

[0004] That is, the rotary type packaging machine has a structure in which a series of processes are sequentially performed step by step on a rotating plate that intermittently rotates, starting from the process of holding packaging such as a pouch on a gripper, the process of opening the opening of the packaging to fill the contents into the held packaging, the process of filling the contents into the packaging with the opened opening through a filling nozzle, the process of sealing the packaging opening using a sealing bar after filling the contents, and the process of completing the packaging by cooling the packaging opening after the sealing is completed.

[0005] The above rotary type packaging machine is divided into a single type that processes one packaging sheet per step through the intermittent rotation of the rotary plate, and a dual type that processes two packaging sheets simultaneously per step. The single type is suitable for relatively heavy packaging, but since only one packaging sheet is packaged per step, it has the disadvantage of low overall product mass productivity. On the other hand, the dual type has a structure that allows for packaging of multiple packaging sheets per step, making it highly suitable for mass production of a variety of products, and therefore has been widely used in the packaging industry recently.

[0006] Fig. 1 shows a conventional single-type rotary packaging machine, in which individual packaging bags (P) supplied through a packaging bag supply section (a) are vertically supported by a gripper (2b) provided on a turn plate (10) and erected, and then the turn plate (10) is rotated to fill contents into the packaging bag (P) through a contents filling section (b), and then the turn plate (10) is continuously rotated to hot-seal the inlet of the packaging bag, and then the packaging bag is dropped from the gripper and taken out.

[0007] FIG. 2 is a schematic drawing of a conventional dual-type rotary packaging machine. The conventional dual-type rotary packaging machine is based on a rotating plate (10) equipped with various link mechanisms that convert the lifting and lowering motion of a roller with respect to a cam surface into the swinging motion of a gripper suitable for holding packaging paper and opening the entrance of a packaging bag (P), and has a structure in which a plurality of grippers (2) are installed at a predetermined interval along the circumference of the rotating plate (10).

[0008] These conventional single rotary packaging machines have low productivity, and dual-type rotary packaging machines have the problem of being very large in size and only being able to produce bags with specifications smaller than those desired by consumers.

[0009] The purpose of the present invention is to provide a mirror-type rotary automatic packaging machine that symmetrically copies five sections of a pure function and performs the same function on the opposite side.

[0010] A mirror-type rotary automatic packaging machine according to the present invention is characterized by including: a rotary plate rotatably installed about a rotation axis; a pair of vacuum chamber rotaries, each of which is sequentially arranged mirror-symmetrically on both sides of a line of symmetry passing through the rotation axis, around the periphery of the rotary plate, wherein a pair of pouch loading and inputting sections, a pair of pouch opening sections, a pair of raw material filling sections, a pair of heat-bonding sealing sections, and a pair of cooling molding sealing and discharging sections are respectively arranged in order and mirror-symmetrically on both sides of the symmetrical line passing through the rotation axis, and sequentially operated according to the rotational motion of the rotation axis; and a gripper arranged in a plurality of groups along the periphery of the rotary plate and installed to hold both sides of a pouch, and moving along a symmetrical rotation section formed on both sides of the rotary plate to sequentially transfer the pouch to each pouch loading and inputting section, each pouch opening section, each raw material filling section, each heat-bonding sealing section, and each cooling molding sealing and discharging section of the pair of vacuum chamber rotaries.

[0011] The above pair of vacuum chamber rotarys may include a first vacuum chamber rotary comprising a first pouch loading and dispensing portion, a first pouch opening portion, a first raw material filling portion, a first heat-bonding sealing portion, and a first cooling molding sealing and discharging portion, which are sequentially arranged around one side of the rotary plate, and a second vacuum chamber rotary comprising a second pouch loading and dispensing portion, a second pouch opening portion, a second raw material filling portion, a second heat-bonding sealing portion, and a second cooling molding sealing and discharging portion, which are sequentially arranged around the facing side of the rotary plate.

[0012] The above-mentioned rotating plate may have a circular shape, and each pouch loading and dispensing section may include a pouch loading platform. The pouch opening section may include a blade that extends from the rotation axis to each pouch opening section, and each raw material filling section may include a hopper for dispensing raw materials into the pouch.

[0013] The device may further include a control panel that controls each pouch loading and feeding section to control feeding of the pouch, controls each pouch opening section to open the entrance of the pouch, controls each raw material filling section to fill the pouch with raw materials, controls each heat-sealing sealing section to heat-seale the open opening of the pouch, and controls each cooling forming sealing and discharge section to cool and form and discharge.

[0014] The existing dual-type rotary packaging machine has a system that is completely identical to the system of the existing single rotary packaging machine, and only adds one device next to the existing device so that two bags can be packaged at a time, but the mirror-type rotary automatic packaging machine according to the present invention symmetrically copies the five sections of the primary function and performs the same function on the opposite side.

[0015] The advantages of the mirror-type rotary automatic packaging machine according to the present invention include twice the productivity compared to a single-type rotary packaging machine, and the machine size is smaller than that of a dual-type rotary packaging machine, and the production of bag products of larger size is possible.
