Description

Technical Field

[0001] The present invention relates to a packaging machine, and more particularly to a mirror-type rotary automatic packaging machine, which puts various raw materials into bags and seals the bag openings. Background Art

[0002] A widely known rotary automatic packaging machine, which breaks away from the existing assembly line-style product packaging in order to more effectively utilize space and improve product mass production, makes the turntable intermittently rotate (stepping motion) along a prescribed arc trajectory, sequentially performing a series of product packaging-related processes.

[0003] The rotary automatic packaging machine uses a method in which packaging paper such as bags (pouches) is loaded onto the packaging machine. The subsequent process, including the supply of packaging paper, the measurement of the packaging contents, the filling of the container, and the sealing of the container mouth, is automatically performed step by step along an arc trajectory.

[0004] In other words, the rotary packaging machine has the following structure: starting from the process of clamping the packaging paper such as a bag on the gripper, the process of opening the packaging paper inlet to fill the clamped packaging paper with contents, the process of filling the packaging paper with contents through the filling nozzle into the packaging paper with the opened inlet, the process of sealing the packaging paper inlet with a sealing bar after filling the contents, and the process of cooling the sealed packaging paper inlet, so that a series of processes to complete the packaging are gradually and sequentially performed on the intermittently rotating turntable.

[0005] The rotary packaging machine, based on the intermittent rotation of the turntable, is available in two types: a single-type packaging machine, which processes one wrapper in a single step, and a dual-type packaging machine, which processes two wrappers simultaneously in a single step. The single-type packaging machine is suitable for heavier packages, but it only processes one wrapper in a single step, resulting in poor overall product mass production. The dual-type packaging machine, on the other hand, can process multiple wrappers in a single step, making it ideal for high-volume production of a wide variety of products. As a result, it has been widely used in the packaging industry in recent years.

[0006] Figure 1 The present invention shows an existing single-type rotary packaging machine, in which a single packaging bag (P) is vertically supported by a clamp (2b) provided on a rotating disk (10), the rotating disk (10) is rotated, and after the packaging bag (P) is filled with content through a content filling part (B), the rotating disk (10) is continued to rotate, and after the entrance of the packaging bag is heat-sealed, the packaging bag is dropped from the clamp and transported to the outside, and the single packaging bag (P) is supplied by a packaging bag supply part (A).

[0007] Figure 2The present invention schematically shows an existing double-type rotary packaging machine. The existing double-type rotary packaging machine is based on a rotating turntable (10) equipped with various connecting rod mechanisms, so that the clamps (2) are arranged at a certain interval along the circumferential surface of the rotating turntable (10) and form a plurality of groups of structures. The various connecting rod mechanisms convert the lifting motion of the roller relative to the cam surface into the swinging motion of the clamp, and the swinging motion is suitable for clamping the packaging paper and opening the entrance of the packaging bag (P).

[0008] The existing single rotary packaging machine has low productivity. The double rotary packaging machine has the problem that it is very large and can only produce sealed bag products with specifications smaller than those required by consumers. Summary of the Invention

[0009] The object of the present invention is to provide a mirror-type rotary automatic packaging machine, which symmetrically replicates the five sections of the forward function so that the other side can also realize the same function.

[0010] According to the present invention, the mirror-type rotary automatic packaging machine includes: a turntable, which is configured to rotate around a rotation axis; a pair of rotators, which make a pair of bag loading and feeding parts, a pair of bag opening parts, a pair of raw material filling parts, a pair of heat bonding sealing parts, and a pair of cooling forming sealing and discharge parts arranged in sequence on both sides in a mirror-symmetrical manner with a symmetry line passing through the rotation axis as a reference around the turntable, and operate in sequence according to the rotation operation of the rotation axis; and a clamper, which is arranged in multiple groups along the periphery of the turntable, configured to grasp both sides of the bag, and move along the symmetrical rotation zone formed by the two side surfaces of the turntable, so as to transfer the bag in sequence to each bag loading and feeding part, each bag opening part, each raw material filling part, each heat bonding sealing part, and each cooling forming sealing and discharge part of the pair of rotators.

[0011] The pair of rotators include: a first rotator, which is composed of a first bag loading and input part, a first bag opening part, a first raw material filling part, a first heat bonding sealing part, and a first cooling forming sealing and discharge part arranged in sequence around one side of the turntable; a second rotator, which is composed of a second bag loading and input part, a second bag opening part, a second raw material filling part, a second heat bonding sealing part, and a second cooling forming sealing and discharge part arranged in sequence around the other side opposite to the turntable.

[0012] The turntable has a disc shape, the bag loading and feeding unit may include a bag loading rack, the bag opening unit may include a blade extending from the rotating shaft toward each bag opening unit, and each raw material filling unit may include a hopper for feeding the raw material into the bag.

[0013] It may further include a control panel, which controls each bag loading and input part, thereby controlling the input of the bags, controls each bag opening part, thereby opening the entrance of the bags, controls each raw material filling part, thereby filling the bags with raw materials, controls each heat bonding sealing part, thereby performing heat bonding sealing on the opened openings of the bags, and controls each cooling molding sealing and discharge part, thereby realizing cooling molding and discharge.

[0014] In the existing double rotary packaging machine, the system is exactly the same as that of the existing single rotary packaging machine, except that a device is added next to the existing device so that two bags can be packaged at a time. However, according to the mirrored rotary automatic packaging machine of the present invention, the five sections of the forward function are symmetrically replicated so that the same function can be achieved on the other side.

[0015] The advantage of the mirror-type rotary automatic packaging machine according to the present invention is that, compared with a single-type rotary packaging machine, the production efficiency is more than twice that of the single-type rotary packaging machine, and compared with a double-type rotary packaging machine, the mechanical specifications are smaller and larger-sized sealed bag products can be produced.
