Description

[0002] Central bundling device of wrapping paper [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a center binding device for wrapping paper, and more particularly to a device for automatically binding openings of a wrapping paper containing contents.

Jumbo roll toilet paper (hereinafter referred to as "jumbo roll") refers to a large roll toilet paper, and is commonly used in public toilets used by many people. Because jumbo rolls are large in size and heavy in weight, it is necessary to pay special attention to packaging so that cleaning personnel can conveniently transport them.

The way in which jumbo rolls are distributed is usually a method in which a certain number of jumbo rolls (usually four units) are packed in a plastic wrapper to form a bundle, and a plurality of bundles are delivered in a paper box. The box provided is stored in a warehouse in the building, and the cleaning staff picks up and transports them as needed.

However, the conventional vinyl packing method is merely a storage rather than a packaging. That is, a jumbo roll was put in a plastic wrapped with one side and then folded simply without opening the open part.

In this case, although it is easy to take out the jumbo roll from the plastic wrapping paper, there is a problem that the wrapping paper can not hold the contents firmly and is difficult to carry. That is, the opening of the plastic wrapper was always open, so the cleaning agent had to carefully carry the jumbo roll bundle using both hands.

In addition, since the open portion of the plastic wrapper is folded at random, there is a problem that the appearance of the product is not clean.

Of course, if the openings of the wrapping paper are tied up after the product is put in, the transporting becomes a little easier. However, the manufacturing efficiency is lowered because the openings must be manually tied, and if the products are simply bundled, the product may not be able to bear the load properly.

On the other hand, Korean Patent Laid-Open No. 10-1996-0034011 (April 22, 1996, "Toilet paper automatic packaging apparatus") relates to a technique related to the technique of wrapping roll toilet paper.

The present invention has been conceived to solve the problems of the prior art as described above, and it is an object of the present invention to provide a jumbo roll which can be easily transported by bundling a product having a center hole formed therein, And to provide a technique for finishing the appearance neatly so as to enhance the merchantability.

According to an aspect of the present invention, there is provided a center binding apparatus for a wrapping paper, comprising: an inner ring having a circular opening with an inner side and a first band connecting portion provided at a plurality of points on a circumference; An outer ring disposed around the inner ring and having a circular shape having a diameter larger than that of the inner ring, a second band connecting portion provided at a plurality of points on the circumference; A plurality of band portions having one side fixed to a specific first band connection portion of the plurality of first band connection portions and the other side fixed to a specific second band connection portion of the plurality of second band connection portions; A rotation driving unit for rotating the inner or outer ring; And the inner ring or the outer ring is rotated in a state where the open portion of the wrapping paper is positioned inside the inner ring and the outer ring so that when the plurality of band portions located outside the opening collect the center of the open portion of the wrapping paper, And bundling means for bundling the openings to form a bundle.

When the wrapping paper enters the inside of the inner ring and the outer ring, the distance between the first band connecting part and the second band connecting part connected to the band part is shortened And when the open portion of the wrapping paper is collected at the center, the inner ring or the outer ring may be rotated such that the distance between the first band connecting portion and the second band connecting portion connected to the band portion is relatively far.

The bundling unit may be a center fusing tip for fusing the opened portion of the wrapping paper.

In the centering device of the wrapping paper according to the present invention, the opening part of the wrapping paper that has been opened for receiving the product is gathered in the center to form a bundling part, so that the product does not come out from the wrapping paper. Therefore, the user can easily carry the handle while grasping the handle with one hand.

In addition, the process of collecting the opening portion of the wrapping paper is performed according to the movement of the band portion connected between the outer ring and the inner ring, and the forming process of the bundling portion is also automatically performed by the center fusion tip. Therefore, Efficiency can be shown.

When the wrapping paper on which the bundle is formed enters the unfolding-preventing fusion apparatus, the open portion of the bundle portion is inserted into the center hole of the product and the fusion portion is formed around the center hole so that the folded wrinkle is not spread and the appearance is neatly finished A rigid packaging structure can be completed.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, some configurations which are not related to the gist of the present invention may be omitted or compressed, but the configurations omitted are not necessarily those not necessary in the present invention, and they may be combined by a person having ordinary skill in the art to which the present invention belongs. .

Although the jumbo roll 10 (large rolled toilet paper) is illustrated and described as an example of a product in which the central hole 11 is formed, the idea of the present invention must be applied to the packaging of the jumbo roll 10 And is applicable to all products in which the central hole 11 is formed.

FIG. 1 is a view for explaining a packaging system to which a central bundling apparatus according to an embodiment of the present invention is applied. As shown in FIG. 1, the packaging system 100 includes a central bundling device 110 and an unfolding fusion device 120. Of course, the packaging system 100 may include means for transporting the jumbo roll 10, means for containing a certain number of jumbo rolls 10 on the wrapping paper 20, a packaging paper 20 containing a certain number of jumbo rolls 10, A means for laying down, a means for transporting the wrapped product, and a means for putting the wrapped product in a box, but is not dealt with in the present invention.

The central bundling device 110 is a device for bundling the openings 21 of the wrapping paper 20 at the center when a certain number of the jumbo rolls 10 are contained in the wrapping paper 20, The openings 21 bundled in the central bundling device 110 are inserted into the central holes 11 of the jumbo roll 10 and the wrinkles 22 of the wrapping paper 20 generated during the bundling process are fused Device. Hereinafter, a description of the unfolding fusion bonding apparatus 120 will be omitted and the central binding apparatus 110 will be described in detail.

Fig. 2 is a plan view (a) and a front view (b) of the central bundling apparatus when the bundling unit and the bundling unit forming means are open in the packaging system shown in Fig. 1, And FIG. 4 is a view for explaining a state in which the outer ring is rotated in the center binding apparatus shown in FIG. 2 to collect the open portion of the wrapping paper.

2 to 3, the center binding device 110 includes an inner ring 111, an outer ring 113, a band portion 115, a rotation driving portion 116, and a bundling portion forming means.

The inner ring 111 is circular with its inner side opened, and the first band connecting part 112 is provided at a plurality of points on the circumference. Here, the inner ring 111 also serves as a frame for supporting other configurations of the central bundling apparatus 110. That is, the inner ring 111 is fixed to the floor, and a circular through hole is formed at the center at the front and rear surfaces, and a first band connecting portion 112 is provided around the through hole.

The outer ring 113 is provided around the inner ring 111 and has a circular shape with a larger diameter than the inner ring 111. The inner ring 113 is open and the second band connecting portion 114 is provided at a plurality of points on the circumference. The outer ring 113 is rotatably mounted on the inner ring 111 via a bearing (not shown).

The band portion 115 is an elastic band having a variable length, and both ends are fixed to the first band connecting portion 112 and the second band connecting portion 114. Therefore, the length of the band portion 115 is variable according to the distance between the first band connection portion 112 and the second band connection portion 114 connected at both ends.

A total of twelve first band connecting portions 112 and second band connecting portions 114 are provided on the inner and outer rings 111 and 113 at intervals of 30 degrees to connect the band connecting portions 112 and 114 to each other And 12 band parts 115 are also installed. That is, the second band connecting portion 114 at the 3 o'clock direction is connected to the band portion 115 at the 12 o'clock direction first band connecting portion 112 and the outer ring 113 at the inner ring 111 on the basis of Fig. 2 (b) The inner ring 111 and the outer ring 113 are rotated in the same manner as in the case of the inner ring 111 at 1 o'clock and the outer ring 113 at 4 o'clock, And a band portion 115 is provided at 2 o'clock.

2 (b), the angle between the both ends of each band portion 115 is 90 degrees with respect to the center of rotation of the outer ring 113, so that the distance between both ends of the band portion 115 is relatively short. However, as the angle between both ends of the band portion 115 increases, the distance between both ends of the band portion 115 becomes longer, and the band portion 115 also becomes more elastic. Theoretically, when the angle between the ends of the band portion 115 is 180 degrees, the distance between both ends of the band portion 115 becomes the longest. At this time, the band portion 115 passes the rotation center of the outer ring 113. That is, in the state of FIG. 2 (b), as the outer ring 113 rotates and the angle between the both ends of the band portion 115 increases, the band portion 115 also faces the rotation center of the outer ring 113.

Referring to FIG. 4B, when the angle between the both ends of the band portion 115 becomes close to 180 degrees (approximately 170 degrees), all the twelve band portions 115 pass near the rotation center of the outer ring 113 . In other words, as the band portions 115 meet, the space of the hexagonal shape formed at the rotation center of the outer ring 113 becomes narrow.

Here, since the twelve band portions 115 move in a state of being adjacent to each other, interference is minimized. 3 is a top view of a portion of the central bundling device 110 to illustrate the connection of the band part 115. FIG. Referring to FIG. 3, the first band connecting part 112 formed on the inner ring 111 and the second band connecting part 114 formed on the outer ring 113 have different height differences with respect to the rotating surface of the outer ring 113. The point at which the band portion 115 is connected to the first band connection portion 112 is lower than the point at which the band portion 115 is connected to the second band connection portion 114. Even if movement of the band portion 115 occurs due to the rotation of the outer ring 113, the respective band portions 115 are connected to the adjacent band portion 115 or the first band portion 115, It is not interfered with the band connection 112 or the interference is minimized (negligible level).

The operation of the band portions 115 will be described again below.

The rotation drive unit 116 is provided for rotating the outer ring 113. The mechanism that rotates the outer ring 113 by the power of the rotation driving unit 116 may be variously implemented. However, in the present embodiment, the rotation driving unit 116 is provided with an example in which the rotation power is transmitted by being engaged with the periphery of the outer ring 113 Respectively.

The bundling portion forming means bundles the opening portion 21 of the wrapping paper 20 and bundles the bundle portion 23 when the banding portion 115 collects the wrapping paper 20 while the banding portion 115 is gathered toward the center of the outer ring 113 by the rotation of the outer ring 113 ).

In the present invention, the expression 'bundling' the opening 21 of the wrapping paper 20 may be used to bind the bundle 20 with a string, but in the functional sense, a more extended definition means that the open portion is unwound Thereby preventing the contents from escaping through the opening 21.

According to the present invention, a center fusing tip 117 for fusing the opened portion 21 of the wrapping paper 20 is applied as the fusing portion forming means. The center fusing tip 117 is provided symmetrically on both sides of the outer ring 113. When the opening 21 of the wrapping paper 20 is gathered by the band portion 115, (21) is heat-pressed on both sides. Accordingly, the packaging paper 20 is temporarily melted and hardened by both the central fusing tips 117, so that the fused portion 23 of the fused shape can be formed, so that the opening 21 is not unfolded again do.

In addition, it is preferable that the cross-section where the central fusion tips 117 on both sides come together and come into contact with each other is a saw tooth shape. This is to secure a maximum welding area within a limited range. If the portion to which the center fusing tip 117 contacts is flat, the fusing area is only the vertical cross-sectional area of the center fusing tip 117. However, if the central fusing tip 117 is in the serrated shape, the fusing of the wrapping paper 20 can be achieved in a much larger area than the vertical cross-sectional area of the central fusing tip 117. Therefore, it is possible to transfer more heat in a large area, and thus the heat fusion fixing becomes more clear.

When the open portion 21 of the wrapping paper 20 is inserted into the triangular groove of the tooth which is the longitudinal end face of the center fusing tip 117, the open portion 21 is heated and pressed in a state of collecting the open portion 21 by the toothed groove, The width of the bundle portion 23 formed by fusion bonding becomes small. If the vertical end face of the central fusing tip 117 is flat, the bundle portion 23 will be formed broadly and the bundle portion 23 will have a large width. This is not only aesthetically pleasing but also disadvantageous when inserted into the center hole 11 of the jumbo roll 10 in the future. That is, in the process of inserting the opening 21 having the bundling portion 23 in the central hole 11, there is a high possibility that the bundling portion 23 having a large area interferes with the peripheral portion of the central hole 11 .

On the other hand, the center fusing tip 117 is disposed immediately in front of the outer ring 113, more specifically, in front of the band portion 115. Therefore, in a state in which the opening portion 21 of the wrapping paper 20 is gathered by the band portion 115, the wrapping paper 20 containing the jumbo roll 10 is immediately transferred through the center fusing tip 117 The bundling portion 23 can be formed.

As an alternative to the central fusing tip 117 of the heating and pressing method, means for bundling the opening 21 of the wrapping paper 20 gathered with a string or means for taping may be applied as a bundling means forming means.

Hereinafter, with reference to FIG. 5, a description will be made of a process of collecting the openings 21 of the wrapping paper 20 at the center by using the central bundling device 110. FIG.

The wrapping paper 20 containing the jumbo roll 10 is introduced into the through hole between the outer ring 113 and the inner ring 111 of the central binding device 110 as shown in FIG.

The wrapping paper 20 is clogged on one side and opened on the other side, and an appropriate number of jumbo rolls 10 are stacked through the opened openings 21 to be stacked. This can be done automatically on a separate device.

The clogged portion of the wrapping paper 20 containing the jumbo roll 10 is first directed to the through hole between the outer ring 113 and the inner ring 111. When all the portions containing the jumbo roll 10 pass through the through hole The open portion of the wrapping paper 20, that is, the open portion 21, is maintained across the outer ring 113. In this state, when the wrapping paper 20 containing the jumbo roll 10 passes through the through hole between the outer ring 113 and the inner ring 111, the distance between both ends of the band portion 115 is adjacent to each other, The planar area of the flat surface should be as shown in Fig. 2 (b). In addition, the center fusing tip 117 should also be opened as shown in FIG. 2 (a).

The wrapping paper 20 containing the jumbo roll 10 passes through the twelve-angled planar space virtually formed by the band portions 115 and then is transported to the open portion 21 of the wrapping paper 20 as shown in FIG. 5 (b) The rotation driving portion 116 rotates the outer ring 113 as shown in Figs. 5C and 4B.

The initial position of the band portion 115 is in a state as shown in FIG. 2 (b). That is, the angle between the opposite ends of the band portion 115 is relatively close to 90 degrees with respect to the center of rotation of the outer ring 113. Therefore, the planar area of the hypothetical hypothetical shape composed of the band portions 115 is relatively large. If the rotation drive unit 116 rotates the outer ring 113 and the distance between the first band connection part 112 and the second band connection part 114 that fix both ends of the specific band part 115 is increased The band portion 115 becomes longer and gets closer to the center of rotation of the outer ring 113 gradually.

Therefore, if the outer ring 113 rotates until the angle between both ends of the band portion 115 becomes approximately 170 degrees, all the twelve band portions 115 are directed to the rotation center of the outer ring 113, the planar area of the hexagonal shape becomes very narrow as shown in Fig. The openings 21 of the wrapping paper 20 located in the imaginary 12-angular planar spaces between the band portions 115 are naturally collected toward the rotation center of the outer ring 113.

The center fusing tip 117 provided on both sides of the outer ring 113 operates as shown in Figs. 5 (c) and 4 (a) to thermally compress both of the openings 21 of the wrapping paper 20 The gathered openings 21 of the wrapping paper 20 are momentarily melted and hardened to form the fused portions 23 of the fused form.

5 (d) and 2 (c), after the band portion 115 collects the open portion 21 of the wrapping paper 20 and the central fusing tip 117 forms the bundling portion 23 by the rotation of the outer ring 113, The center fusing tip 117 is opened again as shown in (a) of FIG. 2, and the rotation driving unit 116 rotates the outer ring 113 again in a reverse direction so that the plane area of the hexagonal shape becomes wider as shown in FIG. 2 (b). The wrapping paper 20 on which the bundling portion 23 is formed in the opening portion 21 is transferred to the unfolding fusing device 120 through the separate transport means (not shown) A portion of the opening 21 formed with the opening 23 is inserted into the central hole 11 of the jumbo roll 10 and a concentric welded portion is formed around the central hole 11 to finish the wrapping paper 20 .

When the wrapping paper 20 is put into the center binding device 110 to form the binding portion 23 at the opening 21 of the wrapping paper 20, A portion blocked by the packaging paper 20 is first inserted into the through hole between the outer ring 113 and the inner ring 111. [ Accordingly, as shown in FIG. 5, when the open portion 21 is gathered and the bundle portion 23 is formed by the center fusion tip 117 in a state where the open portion 21 is located between the band portions 115 later , The wrapping paper 20 containing the jumbo roll 10 is turned in a counterclockwise direction in the drawing so that the opening 21 having the bundling portion 23 formed thereon can be positioned in the upward direction. Therefore, the process of inserting and fusing the opening 21 into the center hole 11 can be facilitated even if the position of the additional wrapping paper 20 is not changed for the subsequent process.

6 is a view for explaining a wrapping paper in which the openings are bundled at the center by using the central bundling apparatus shown in FIG.

6, the underside of the wrapping paper 20 is in a closed state, and a knob 26 is provided at this portion. The upper side of the wrapping paper 20 is initially opened and the jumbo rolls 10 are housed inside the wrapping paper 20 through the opening 21. The remaining portions of the wrapping paper 20, that is, the openings 21, are gathered at the center of the central bundling apparatus 110 and then fused to form the bundling portions 23 above the jumbo rolls 10. Therefore, since the opening 21 is not closed in a clogged state, the user can grip the grip 26 with one hand and carry the wrapping paper 20 containing the jumbo roll 10.

The wrapping paper 20 may be made of vinyl material or the like so that the wrinkles 22 are necessarily formed in the process of gathering the opening 21 of the wrapping paper 20 in the center in the central binding device 110. That is, since the opened wrapping paper 20 is gathered in a narrow space, the opening portion 21 is folded and the fold 22 is generated.

Of course, since the opening portion 21 is tied, a large problem does not occur even if the user grasps and transports the grip 26. However, if the jumbo roll 10 is transported with the grip 26 downward in the wrapping paper 20 state of FIG. 6, the load of the jumbo roll 10 is concentrated on the portion where the wrinkles 22 are formed. In this case, it is also possible that the folded wrinkles 22 are unfolded during the conveying process so that the opening 21 is opened or opened.

To this end, the jumbo roll 10 wrapping paper 20 in which the open portion 21 of the wrapping paper 20 is bundled and bundled in the central bundling apparatus 110 enters the fusion bonding apparatus 120 for spreading prevention, The open portion 21 formed with the bundle portion 23 is inserted into the center hole 11 of the jumbo roll 10 to form a clean appearance and then a fused portion is formed around the center hole 11. Then, Since the corrugations 22 are fixed by the fused portion, even if an external force is applied, the possibility that the corrugated portion 22 is unfolded and the open portion 21 is broken can be prevented in advance.

As described in detail above, the central bundling device 110 of the wrapping paper 20 according to the present invention collects the opening 21 of the wrapping paper 20, which has been opened for storing the product, So that the product does not come out of the wrapping paper 20. Therefore, the user can easily carry the handle 26 while grasping the handle 26 with one hand.

The process of collecting the opening 21 of the wrapping paper 20 is performed according to the movement of the band portion 115 connected between the outer ring 113 and the inner ring 111. The process of forming the bundling portion 23 is also the same as that of the center fusion tip The process efficiency can be fast and accurate as compared with the case where the open portion 21 is manually tied.

When the wrapping paper 20 on which the bundling section 23 is formed enters the fusion bonding apparatus 120 for unfolding expansion, the opening 21 of the bundling section 23 is inserted into the center hole 11 of the product, By forming the fused portion around the hole 11, the folded wrinkles 22 can be unfolded, and the appearance can be neatly finished and a solid packaging structure can be completed.

In the above description, the inner ring 111 functions as a frame for supporting other structures, and the outer ring 113, which is rotatably installed on the inner ring 111 via a bearing (not shown), rotates The outer ring 113 is fixed to perform the function of a frame supporting the other structures. After the inner ring 111 having a relatively small diameter is rotatably installed on the outer ring 113, The driving portion 116 may rotate the inner ring 111 to cause the band portion 115 to move.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
