Description

Technology Field

[0001] The present invention relates to a high-speed sealing machine using a rotary guide. In particular, the box supply utilizes a box supply side belt and an acceleration lower servo belt to open the box when the box is opened, and the rotary guide servo device continuously drives a rotary guide for folding the box flap according to the box position to fold the flap, then apply hot melt adhesive, seal, and discharge the box. Background Technology

[0003] Generally, to deliver goods to consumers or others, they are placed in a standard-sized box, sealed, and then shipped to prevent damage.

[0004] In the past, such work, namely putting items into a box and folding the flaps to tape them, was done manually, which increased labor costs and lowered productivity, and consequently increased the cost of the items.

[0005] Accordingly, a box sealing machine was developed that automatically taps the flaps of a box while the goods are placed in the box, thereby increasing production efficiency through improved workability and reducing the burden of labor costs, making it possible to reduce the cost of goods.

[0006] In the conventional production method, only one product of the same size was produced on a single line. However, with the recent continuous production of new products in response to diverse consumer demands, it is now required to produce various products simultaneously on existing lines and package them in different types of boxes, rather than installing separate production lines for each new product to improve productivity and efficiency.

[0007] As shown in FIG. 1, a conventional sealing machine transfers a box (12) from a box supply inlet (11) in a chain transfer manner using a box transfer attachment (17). At this time, the box spacing control is mainly based on a mechanical structure, and when the flap is folded, the inner flap is folded once each time the box is moved through a single folding mechanism that rotates using an inner flap folding cylinder (13) at the rear end. At this time, the outer flap of the box is a fixed guide and cylinder combination method that is controlled by a box outer flap guide up and down adjustment device (14).

[0008] In addition, in the case of hot melt bonding, a box hot melt bonding part (15) is fixedly installed on the upper part, and the nozzle angle is 20 degrees, and the following ability according to the box height is limited, and in the case of the upper guide, it is mechanically adjusted after hot melt, and when the box size is changed, manual adjustment by the upper guide adjustment part (16) after box hot melt bonding is required.

[0009] In conclusion, conventional sealing machines consisted simply of cylinders and mechanical structures, resulting in low responsiveness to changes in box specifications and limitations in speed and precision control. Prior art literature

Effects of the invention

[0017] The present invention, as described above, utilizes a side belt and a lower belt for acceleration to open the box for supplying the box, and a rotary guide servo device continuously drives a rotary guide for folding the box flap according to the box position to fold the flap, then apply hot melt adhesive and seal it to discharge the box, thereby increasing responsiveness to changes in box specifications and enabling speed and precision control. Brief explanation of the drawing

[0019] FIG. 1 is a drawing showing a conventional box sealing machine. FIG. 2 is a drawing showing a high-speed sealing machine using a rotary guide of the present invention. FIG. 3 is a detailed view of the rotary guide servo device of the present invention. Specific details for implementing the invention

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0021] FIG. 2 is a drawing showing a high-speed sealing machine using a rotary guide of the present invention, and FIG. 3 is a detailed drawing of a rotary guide servo device for folding an inner flap at the rear end of a box according to the present invention. As shown in the figure, the device is composed of a lower belt conveyor (1) for accelerating a box to spread the box spacing, a side belt (2) for supplying a box, a box (3) being transported by the side belt (2) for supplying a box, a rotary guide (4) for folding a box flap to fold an inner flap at the rear end of the box when the box (3) is brought in, a box outer flap guide up and down adjustment device (5) installed at the rear end of the rotary guide (4) for folding a box flap, an upper guide automatic adjustment servo device for automatically adjusting an upper guide after hot melt bonding of the box, a box pressing conveyor (6) for pressing the box while the inner flap at the rear end of the box is folded by the rotary guide (4) for folding a box flap, and a box transport attachment (7) for transporting a sealed box.

[0022] However, the above box spacing is controlled by servo acceleration, and the upper guide is configured to be automatically servo-adjusted.

[0023] The operation of the present invention configured as described above will be explained step by step.

[0024] First, the box supply and transfer steps of the present invention are as follows.

[0025] First, the box (3) is fed from the supply unit and transported to the sealing process via the side belt (2) and the lower belt conveyor (1). At this time, stable high-speed transport is possible by automatically adjusting the spacing between boxes through servo acceleration control, and the lower belt conveyor (1) for box acceleration is used to widen the spacing between boxes.

[0026] That is, in the present invention, automatic box spacing (acceleration control) is performed by the lower servo belt through the combination of the side belt (2) + lower belt conveyor (1).

[0027] Second, the flap folding operation steps of the present invention are as follows.

[0028] During box transport, the inner flap at the rear end of the box is folded in a rotating guide manner by the box flap folding rotating guide (4), and at this time, servo control is applied so that the accurate folding position can be maintained even with changes in box dimensions.

[0029] That is, the folding of the inner flap at the rear end of the box (3) is controlled by a rotating guide (4) for folding the box flap, and the box size can be adjusted using a servo position value.

[0030] Third. The hot melt bonding step of the present invention is as follows.

[0031] The rear inner flap of the box (3) is folded by the box flap folding rotary guide (4), and hot melt is applied from the top after the flap is folded. The application timing and position are maintained consistently in conjunction with the servo transfer, thereby improving the adhesive quality.

[0032] In other words, the application timing and positional accuracy are improved through servo-controlled transfer while the nozzle is maintained at 20 degrees.

[0033] Fourth, the upper and outer flap guide control steps of the present invention are as follows.

[0034] As described above, after hot melt bonding, the upper guide and outer flap guide are automatically height-adjusted via a servo device, allowing for rapid adaptation to various box sizes.

[0035] That is, after hot melt bonding of the box, the upper guide can be adjusted in height using the box outer flap guide upper and lower adjustment device (5) and the upper guide automatic adjustment servo device, and the upper and lower parts of the box outer flap guide can also be servo controlled.

[0036] However, the box outer flap guide upper / lower adjustment device (5) and the upper guide automatic adjustment servo device are configured as a single unit.

[0037] Fifth, the sealing stabilization step of the box is as follows.

[0038] In the sealing section, the box is stably compressed through the box pressing conveyor (6), box pressing roller, and side belt, and in this process, sealing defects and appearance defects can be minimized.

[0039] Meanwhile, as an additional stabilization element, a box pressing roller can be applied, and shaking of the box can be minimized by side belt transport, and when the box sealing is completed, it is transported through the box transport attachment (7).

[0040] Accordingly, the present invention can significantly improve automation, precision, flexibility, etc. through a servo-centered structure, and is excellent for high-speed operation and adaptation to changes in specifications. This difference can be clearly understood by referring to [Table 1], which is a comparison table with the following prior art.
