[0019] The conveyors (111, 112, 113) are provided in multiple numbers to transport the product (1) with measured specifications. The conveyors (111, 112, 113) are, for example, belt conveyors, but are not necessarily limited thereto and can be configured with various types of transport devices, including roller conveyors. As in the present embodiment, the rear conveyor (113) can be configured as a roller conveyor, thus forming a different type of transport device. However, they are not limited thereto and can be configured with various arrangement types and numbers corresponding to the packaging path of the product (1).

[0020] In order to measure the specifications of the product (1) supplied through the conveyors (111, 112, 113), a device for measuring the specifications of the product (1) may be installed at the front end of the conveyor (111) on the front side. For example, the device for measuring the dimensions of the product (1) can be configured such that, due to an array structure in which multiple optical sensors are arranged horizontally on the upper side of the product and multiple optical sensors are arranged vertically on the side of the product, the height and width of the product (1) are measured according to the number and position of the optical sensors that recognize the product, and the front-to-back length of the product (1) is measured from the conveying speed of the product (1) being transported by the conveyor (111) and the time required for the product (1) to pass through as measured by the optical sensors. As another example, the device can be configured to measure the dimensions of the product (1) using a laser displacement sensor. As yet another example, the dimensions of the product (1) can be obtained as information through image processing of the product (1) using a vision measurement sensor. As yet another example, the dimensions of the product (1) can be obtained as information through the shape and cross-section measurement of the product (1) using a profile sensor. In addition to this, the dimensions of the product (1) can be obtained in various other ways.

[0021] The packaging film supply unit (120) is folded in the longitudinal direction to form two layers, and also supplies a packaging film (2) capable of heat sealing and cutting to the conveyor (111, 112, 113).

[0022] The packaging film supply unit (120) may include at least one guide roller (121) for guiding the movement of the packaging film (2) to ensure a path and smoothness necessary for supplying the packaging film (2), and may be configured to continuously supply the packaging film (2) using the conveying force of the product (1) by the conveyor (111, 112, 113), and may be configured to provide the conveying force of the packaging film (2) using the frictional force of the guide roller (to which driving force is applied), and may also be configured to convey the packaging film (2) by various other methods.

[0023] The guide section (131, 132) guides the packaging film (2) supplied by the packaging film supply section (120) to be supplied with each side spread open on the upper side of the conveyor (111, 112, 113). For example, as in the present embodiment, each can be formed in the shape of a right triangle and is installed on the upper and lower sides of the front conveyor (111) among the conveyors (111, 112, 113), thereby guiding the packaging film (2), which was supplied to the upper and lower sides of the front conveyor (111) with each side spread open, to be supplied to the upper side of the subsequent conveyor (112) by switching the packaging film (2), which was supplied to the upper and lower sides of the front conveyor (111) with each side spread open (see FIG. 4).

[0024] The cutout section (140) is installed vertically between the conveyors (111, 112, 113), specifically the front conveyor (111) and the subsequent conveyor (112), so that when a product (1) is fed into the packaging film (2) opened by the guide section (131, 132) by the operation of the conveyor (111, 112, 113), specifically the front conveyor (111), the rear end of the product (1) in the packaging film (2) is heat-sealed and cut in the width direction.

[0025] The cutout section (140) may be installed vertically between the front conveyor (111) and the subsequent conveyor (112). For this purpose, for example, it may include a base (141) installed to be located on the lower side between the front conveyor (111) and the subsequent conveyor (112), a heating cutter (142) installed to be vertically movable on the upper side of the base (141), a guide (143) composed of a guide rail, a sliding coupling member, or a guide shaft to guide the vertical movement of the heating cutter (142), and a cut drive unit (144) for vertically moving the heating cutter (142). The cut drive unit (144) may use a rotary motor to convert the rotational driving force into linear motion to provide the lifting driving force of the heating cutter (142), or may use a linear actuator such as a cylinder or a linear motor, and various other linear motion devices may also be used.

[0026] The base (141) may have the same or similar shape as the heating cutter (142), may be installed facing the heating cutter (142), and may be made of a material that withstands the heat of the heating cutter (142) and also withstands the cutting force of the heating cutter (142).

[0027] A heating cutter (142) may be connected to and installed in a cutting drive unit (144), and a heater may be provided to provide heat for heat sealing or heat fusion of the packaging film (2). A cutter for cutting the packaging film (2) and a sealing member that receives heat from the heater and seals the packaging film (2) may be formed to form a single body, or they may be formed separately and arranged side by side with each other. In addition, they may be formed or arranged in various other ways. If the sealing member is formed separately from the cutter, multiple sealing members may be provided to be arranged on both sides with the cutter in between. A heat conducting member may also be provided to uniformly transfer heat from the heater to the sealing member.

[0028] The trimming section (150) is installed on the side of the conveyor (111, 112, 113), specifically the rear conveyor (113), and heat-seals the open side of the product receiving packaging film (2) that is moved by the conveyor (111, 112, 113) with the front and rear ends sealed by the continuous operation of the cutout section (140).

[0029] The trimming unit (150) may include a base (151) on which the rear side of the conveyor (113) is located, a heating cutter (152) that can be located above the base (151) and cuts the product receiving packaging film (2) located between the base (151) and the base by pressing downward to seal it with heat, a trimming drive unit (153) that raises and lowers the heating cutter (152), and a mounting stand (154) installed so that the trimming drive unit (153) is connected to the heating cutter (152). A guide part for guiding the raising and lowering of the heating cutter (152) may be provided on the mounting stand (154).

[0030] The base (151) may have the same or similar shape as the heating cutter (152), may be installed facing the heating cutter (152), and may be made of a material that withstands the heat of the heating cutter (152) and also withstands the cutting force of the heating cutter (152).

[0031] A heating cutter (152) may be connected to and installed in a trimming drive unit (153), and a heater may be provided to provide heat for heat sealing or heat fusion of a product receiving packaging film (2). A cutter for cutting the product receiving packaging film (2) and a sealing member that receives heat from the heater and seals the product receiving packaging film (2) may be formed to form a single body, or they may be formed separately and arranged side by side with each other. In addition, they may be formed or arranged in various other ways. If the sealing member is formed separately from the cutter, multiple sealing members may be provided to be arranged on both sides with the cutter in between. A heat conducting member may also be provided to uniformly transfer heat from the heater to the sealing member.

[0032] The position variable section (170) moves the product receiving packaging film (2) to the trimming section (150) on the conveyor (111, 112, 113), specifically on the rear conveyor (113).

[0033] Referring to FIG. 3, the position variable unit (170) can be positioned higher than the rollers (113a) by the lifting drive unit (173) so that the conveyor belt (172), which is installed to move in an endless loop along the longitudinal direction of the rollers (113a) of the roller conveyor corresponding to the rear conveyor (113; see FIG. 1 and FIG. 2), is positioned higher than the rollers (113a) by the lifting drive unit (173) to support and transport the product receiving packaging film (2) that was supported by the rollers (113a). Here, the conveyor belt (172) can be supported at least at both ends by belt rollers (not shown) to move in an endless loop, and the rotational driving force of a rotary motor is applied to one of the belt rollers, and all belt rollers can be installed to be rotatable by the roller bracket (171). That is, a number of belt rollers arranged along the longitudinal direction of the roller (113a) of the roller conveyor by the roller bracket (171) can support the conveyor belt (172) to move in an endless loop. This roller bracket (171) is connected to the lifting drive unit (173) so that it moves up and down together with the conveyor belt (172). For example, when the conveyor belt (172) protrudes from the roller (113a) that has stopped rotating by being raised (A) by the lifting drive unit (173) and moves in an endless loop, it supports and conveys the product receiving packaging film (2) that was supported by the roller (113a) instead. When the product receiving packaging film (2) is transported to the trimming section (150) by the operation of the lifting drive unit (173), the roller bracket (171) returns to a lower position (B) than the roller (113a) together with the conveyor belt (172), thereby allowing the trimming process of the product receiving packaging film (2) to be performed by the trimming section (150), and when this is completed, the product receiving packaging film (2) can be transported along a predetermined path through the rear conveyor (113).

[0034] The control unit (180) receives information regarding the specifications of the product (1) loaded to the trimming unit (150) and controls the position variable unit (170) to transport the packaging film (2) to a trimming position that meets the over-packaging prevention standard set according to the specifications of the product (1). Here, the over-packaging prevention standard can be a standard for packaging specifications that are not considered over-packaged with respect to the specifications of the product (1), but due to the characteristics of the packaging, it is not necessary to define it precisely, and it can be appropriately determined by the user within a range having a size of 100 to 200% of the size of the corresponding part of the product (1), and the trimming position on the open side of the product receiving packaging film (2) can be determined by the control of the position variable unit (170) according to the specifications of the product (1). In addition, to enable position control by the control unit (180), various actuators including the motor used in the present invention may be devices capable of controlling the rotation angle or driving distance.

[0035] In one embodiment of the present invention, a one-sided trimming type automatic packaging system (100) for compliance with the overpackaging prevention standard may additionally be provided with a scrap recovery unit (160) that collects and recovers scrap cut from the packaging film (2) by the trimming unit (150).

[0036] The scrap recovery unit (160) comprises a scrap gripper (161) that allows the end of a packaging film (2) to be trimmed by a trimming unit (150) to be gripped by a finger (161a) that performs closing and opening operations by a grip driving unit (161b); a gripper shaft (162) that is installed parallel to one side of the trimming unit (150) and fixed so that the scrap gripper (161) rotates together with it; a shaft driving unit (163) that allows the scrap gripper (161) to drop the scrap by rotating the gripper shaft (162) when the end of the product receiving packaging film (2) held by the scrap gripper (161) is cut by the trimming unit (150) and becomes scrap; a collection duct (164) provided to allow scrap to flow into the lower side of the scrap gripper (161); and the collection duct (164) that [receives] the scrap It may include a blower (165) that provides airflow for suction.

[0037] The scrap gripper (161) can be connected to the grip drive unit (161b) so that each of the pair of fingers (161a) rotates around a parallel hinge axis, and when the fingers (161a) are closed to 0 degrees while extended to 180 degrees, it is possible to grip the scrap. To this end, the grip drive unit (161b) can be configured to rotate the fingers (161a) by the rotational driving force of a motor, the driving force transmitted by a cylinder and a link member, or various other methods.

[0038] The grip shaft (162) can be rotatably installed on, for example, a mounting base (154), and by rotating it by means of a shaft member (163) that provides rotational force by means of a motor, etc., the position of the scrap gripper (161) can be rotated so that the scrap placed by the fingers (161a) spreads can be smoothly collected on the side of the collection duct (164) by its own weight.

[0039] The collection duct (164) can be connected to an external collection container, and scrap sucked in by the blowing force of the blower (165) can be collected in this collection container to perform subsequent processing.

[0040] According to the one-sided trimming type automatic packaging system for compliance with the overpackaging prevention standards of the present invention, by preventing overpackaging of a product, it is possible to align with the trend of minimizing packaging through the reduction of packaging materials at the source, and furthermore, it not only provides consumers with a positive perception of resource conservation but also eliminates negative perceptions regarding product exaggeration and has the effect of preventing a decrease in repurchase due to damage to the credibility of the product brand.
