Abstract

The present invention relates to a packing system including a transporting device, an erecting device, and a guiding device. The packing system is configured to reduce the number of packing operations and to simplify the packing process, thereby improving production efficiency, compared with a conventional system. The packing system is configured to minimize wrinkling of a packing material and to adjust position of ends of the packing material in a way that the packing material is always supplied to a predetermined position, thereby reducing a failure rate of a packed product. It is possible to pack various sizes of packing target objects using a single system.

First claim

The invention claimed is:

1. A packing system, comprising:
a transporting device transporting a packing material and a packing target object provided on the packing material;
an erecting device including a pair of parts, which are placed near an end of the transporting device and are spaced apart from each other, the erecting device being configured to allow width-directional both ends of the packing material entered into the transporting device to be transported in a direction perpendicularly crossing a transportation direction of the packing material and in a standing manner; and
a guiding device allowing the width-direction both ends of the packing material transported by the transporting device to become close to each other and guiding the packing material to be folded and packed toward a top surface of the packing target object; and
an endpoint positioning device that presses one and opposite end portions of the packing material, which are moved toward each other during passing through the guiding device, and that allows the one and opposite end portions of the packing material to pass therethrough in a direction of the packing material transported by the transporting device,
wherein the endpoint positioning device comprises:
a pair of first rollers configured to rotate in opposite directions, with the one end portion of the packing material interposed therebetween, thereby allowing the packing material to pass therethrough;
a pair of second rollers configured to rotate in opposite directions, with the opposite end portion of the packing material interposed therebetween, thereby allowing the packing material to pass therethrough; and
a detection part configured to sense positions of the one and opposite ends of the packing material passing through the first pair of rollers and the second pair of rollers, thereby allowing the one end or the opposite end of the packing material to be tightened or loosened by the first pair of rollers or the second pair of rollers, and
wherein the endpoint positioning device comprises a structure, in which rotation speeds of the first pair of rollers and the second pair of rollers are adjusted depending on a transportation speed of the packing target object transported by the transporting device.

2. The packing system of claim 1 , wherein the guiding device is configured to include a pair of a first guide body and a second guide body, which are spaced apart from each other and face each other,
the guiding device is spaced apart from the packing target object and is placed on the transporting device to be in contact with the packing material, which is erected by the erecting device and is in motion, thereby providing a space, allowing the packing material to be folded toward the top surface of the packing target object, and
a space between the first guide body and the second guide body decreases in the transportation direction of the packing target object.

3. The packing system of claim 2 , wherein the guiding device comprises a structure configured to adjust a space between the pair of separate facing the first and second guide bodies depending on one or both of a size and a material of the packing target object.

4. The packing system of claim 1 , wherein the erecting device has a triangular vertical section shape, and the packing material is in contact with an inclined surface of the erecting device.

5. The packing system of claim 4 , wherein the inclined surface of the erecting device has an adjustable angle with respect to a horizontal plane.

6. The packing system of claim 1 , further comprising a tension adjusting device pressing the packing material to be entered into the transporting device.

7. The packing system of claim 6 , wherein the tension adjusting device comprises one or more of a pressing-position adjusting member, which is provided in the transporting device and adjusts a pressing position of the packing material, and a direction-changing rod, which changes a direction of the packing material to be entered into the transporting device.

8. A packing method, comprising:
an input step of inputting a packing material and a packing target object placed on the packing material into a transporting device;
a packing material erecting step of transporting the packing material transported by the transporting device in a direction perpendicularly crossing a transportation direction and in a standing manner, using a pair of separated erecting devices provided at an end of the transporting device;
an endpoint closing step of allowing width-directional both ends of the packing material transported by the transporting device to become close to each other through a guiding device;
an endpoint positioning step of pressing one and opposite end portions of the packing material, which are moved toward each other through the endpoint closing step, using an endpoint positioning device, and of passing the one and opposite end portions of the packing material in a direction of the packing material transported by the transporting device; and
a packing step of folding and packing the both ends of the packing material toward a top surface of the packing target object, using the guiding device,
wherein the endpoint positioning device comprises:
a pair of first rollers configured to rotate in opposite directions, with the one end portion of the packing material interposed therebetween, thereby allowing the packing material to pass therethrough;
a pair of second rollers configured to rotate in opposite directions, with the opposite end portion of the packing material interposed therebetween, thereby allowing the packing material to pass therethrough; and
a detection part configured to sense positions of the one and opposite ends of the packing material passing through the first pair of rollers and the second pair of rollers, thereby allowing the one end or the opposite end of the packing material to be tightened or loosened by the first pair of rollers or the second pair of rollers, and
wherein the endpoint positioning device comprises a structure, in which rotation speeds of the first pair of rollers and the second pair of rollers are adjusted depending on a transportation speed of the packing target object transported by the transporting device.

9. The method of claim 8 , wherein the guiding device is configured to include a pair of a first guide body and a second guide body, which are spaced apart from each other and face each other,
the guiding device is spaced apart from the packing target object and is placed on the transporting device to be in contact with the packing material, which is erected by the erecting device and is in motion, thereby providing a space, allowing the packing material to be folded toward the top surface of the packing target object, and
a space between the first guide body and the second guide body decreases in the transportation direction of the packing target object.

10. The method of claim 9 , wherein the guiding device comprises a structure configured to adjust a space between the pair of separate facing the first and second guide bodies depending on one or both of a size and a material of the packing target object.

11. The method of claim 8 , wherein the erecting device has a triangular vertical section shape, and the packing material is in contact with an inclined surface of the erecting device.

12. The method of claim 11 , wherein the inclined surface of the erecting device has an adjustable angle with respect to a horizontal plane.

13. The method of claim 8 , further comprising a tension adjusting step of adjusting tension of the packing material to be entered into the transportin
