1 is a view for explaining an apparatus for manufacturing an interdental hygiene tool that can be used together with a dental floss tool and an interdental brush according to an embodiment of the present invention.

In the interdental hygiene tool according to the present embodiment, a dental floss is provided on one side and an interdental brush is provided on the other side so that the floss function and the interdental brush function can be used as a single product. In addition, the interdental hygiene device manufacturing apparatus according to the present embodiment is not performed at a distance in various processes having a temporal difference or in various facilities having a spatial difference in manufacturing of components for the dental floss function and the interdental brush function. In a single process, it is sequentially automated and performed.

For this purpose, the interdental hygiene device manufacturing apparatus according to this embodiment includes a winding unit 110, a first forming unit 120, a second forming unit 130, a heat treatment unit 140, a collection rod unit 150, and a transfer unit ( 160).

The winding unit 110 is provided in a state in which the dental floss 210 is wound, and serves to place the wound dental floss 210 in a partially unwound state to be placed on the first molding unit 120. This winding unit 110 may play a role of pulling the dental floss with a predetermined level of tension in order to prevent the dental floss 210 from being indiscriminately released.

However, as will be described later, when the dental floss is molded in the wound dental floss 210 and is combined with the dental floss, the position of the dental floss may be misaligned or may be implemented so as not to have a tension enough to pull the dental floss.

In some cases, such a winding unit 110 may allow one dental floss 210 line to be laid loose on the first forming unit 120, and two or three or more lines may be included in the first forming unit 120 together. It can also be implemented to be laid loose.

Hereinafter, for convenience of description, a description will be made on the premise that the two dental floss 210 lines are released together in the first molding part 120.

The line of the dental floss 210 partially unwound from the winding part 110 is seated on the first molding part 120 to be integrated with the dental floss molded in the first molding part 120.

The first molding part 120 is composed of a first upper mold 121 and a first lower mold 125, and the first upper mold 121 and the first lower mold 125 are opened and closed. As it repeats, the process of molding the dental floss and the process of transferring the formed dental floss to the second molding part 130 are repeated.

That is, the dental floss is molded in a state where the first upper mold 121 and the first lower mold 125 are closed, and the first upper mold 121 and the first lower mold 125 are opened. The dental floss is transferred to the second molding unit 130.

Both the first upper mold 121 and the first lower mold 125 are closed to form a cavity, and a molding resin is injected into the cavity to form a dental floss.

The cavity of the first molding part 120 has a shape corresponding to a state in which the interdental brush is excluded from the interdental hygiene tool that can be used together with a dental floss tool and an interdental brush as a final product.

In addition, the molding resin injected into the cavity of the first molding part 120 may be a material such as PE or PP.

On the other hand, the dental floss 210 partially unwound from the winding part 110 is seated on the first molding part 120, and the first molding part 120 and the first upper mold 121 and the dental floss 210 are seated. The first lower mold 125 is closed and a cavity is formed so that the dental floss 210 is hooked and connected to the dental floss molded in the first molding part 120.

In particular, the dental floss 210 partially unwound from the winding unit 110 is arranged in a position corresponding to the floss table of the dental floss among the cavities formed by closing the first upper mold 121 and the first lower mold 125, and When the dental floss is molded in the first molding part 120 in a state in which the dental floss 210 is hung in the dental floss.

In addition, when there are two dental floss 210 lines as described above, the first upper mold 121 and the first lower mold 125 are provided to form a cavity corresponding to each dental floss on the left and right. , When manufactured to mold a total of 7 dental floss in one dental floss 210 line, the first upper mold 121 and the first lower mold 125 correspond to a total of 14 dental floss, 7 each on the left and right It may be provided to form a cavity.

Hereinafter, for convenience of explanation, two dental floss 210 lines are used, and a description will be made on the premise that 7 dental floss are formed in each dental floss 210 line.

On the other hand, for simultaneous molding of a total of 14 dental floss provided in the two dental floss 210 lines as described above, the cavity has not only the shape of 14 dental floss, but also a runner and a runner and 14 dental floss as a passage through which the molding resin is discharged. It may have a shape including a shape of a plurality of gates each connecting the other side.

That is, the molding resin is injected through the runner, and is injected into the shape of each of the 14 dental floss via a gate connected from the runner to each of the 14 dental floss.

After the molding of the dental floss is completed in the first molding part 120, the dental floss is transferred to the second molding part 130 by the transfer part 160.

In this way, when the dental floss is transferred to the second molding unit 130, the dental floss 210 is connected to the dental floss, so the dental floss 210 wound around the winding unit 110 is the transfer unit 160 2 As much as the distance transferred to the forming part 130 is unwinding.

As described above, the winding unit 110 can wind the dental floss 210 with a predetermined level of tension, but has a force in a direction opposite to the direction in which the conveying operation is performed by the conveying unit 160, so the conveying unit 160 ), the position of the dental floss is distorted or pulled up to the dental floss by interfering with the transfer operation, or in particular, the tension should not be set too large so that a situation in which the dental floss 210 is broken does not occur.

The second molding part 130 is composed of a second upper mold 131 and a second lower mold 135, and the second upper mold 131 and the second lower mold 135 are opened and closed. As it repeats, the process of forming the interdental brush and the process of transferring the dental floss to which the formed interdental brush is attached to the heat treatment unit 140 are repeated.

That is, the interdental brush is formed in the state where the second upper mold 131 and the second lower mold 135 are closed, and the interdental brush is formed in the state where the second upper mold 131 and the second lower mold 135 are open. The dental floss with the brush attached is transferred to the heat treatment unit 140 and at the same time the dental floss formed in the first forming unit 120 is transferred.

The second upper mold 131 and the second lower mold 135 are both closed to form a cavity, and a molding resin is injected into the cavity to form an interdental brush.

The cavity of the second molding part 130 has a shape corresponding to an interdental hygiene tool that can be used together with a dental floss tool and an interdental brush, which is a final product, but has a shape that is blocked so that the molding resin is not injected into the part except the interdental brush. Have.

That is, the cavity of the second shaping part 130, as well as the interdental brush, has a shape including a runner and a gate for forming a dental floss part and a dental floss part previously formed in the first shaping part 120. Although formed, it may be formed such that additional injection of the molding resin is impossible in the dental floss portion, runner and gate excluding the interdental brush.

To this end, the second molding part 130, unlike the first molding part 120, does not have a single molding resin injection part (not shown), but has a total of 14 molding resin injection parts (not shown) individually. I can.

In addition, the molding resin injected into the cavity of the second molding part 130 may be a material such as rubber or silicone.

After the formation of the interdental brush is completed in the second forming part 130, seven one side of the dental floss is connected to the dental floss 210 of two lines, and the interdental brush is molded on the other side of each dental floss.

The moldings that have passed through the first and second molding units 120 and 130 are transferred to the heat treatment unit 140 by the transfer unit 160.

When the molded product is transferred to the heat treatment unit 140 in this way, since the dental floss 210 is connected to the molded product, the dental floss 210 wound around the winding unit 110 is transferred to the heat treatment unit 140. It is additionally unwinding as much as the distance transferred to.

The heat treatment unit 140 cuts unnecessary parts by applying heat to the moldings received from the second molding unit 130 by the transfer unit 160 and cuts unnecessary parts of the dental floss 210 so that the moldings can be used as interdental hygiene tools. Plays a role. This will be described in more detail later.

The heat treatment unit 140 may be implemented so that the top and bottom constitute one set, and the first heat treatment unit 141 on the upper and the second heat treatment unit 145 on the lower part are in different parts according to the design change. It may be implemented to apply heat, or it may be implemented to apply heat by engaging the same parts with each other.

Interdental hygiene tools, in which unnecessary portions of the dental floss 210 are cut off by heat treatment in the heat treatment unit 140 are transferred to the collection rod unit 150 by the transfer unit 160.

On the other hand, since an unnecessary portion of the dental floss 210 is cut by the heat treatment unit 140, the dental floss 210 is not further unwound as the interdental hygiene tool is transferred to the collection rod unit 150.

However, the operation of forming the dental floss by the first forming unit 220, the operation of forming the interdental brush by the second forming unit 230, and the operation of performing heat treatment by the heat treatment unit 140 are synchronized with each other and performed simultaneously. At the timing when the interdental hygiene tools are transferred from the heat treatment unit 140 to the collection rod unit 150, the dental floss molded in the first molding unit 220 is transferred to the second molding unit 230, and the second molding Since the interdental brush formed in the unit 230 is transferred to the heat treatment unit 140, the dental floss 210 may be additionally unwound by the transfer operation in the first and second shaping units 220 and 230. I would say only.

In addition, the operation of forming the dental floss by the first forming unit 220, the operation of forming the interdental brush by the second forming unit 230, and the operation of performing heat treatment by the heat treatment unit 140 are synchronized with each other. By doing so at the same time, more economical and efficient automated mass production becomes possible.

The collection rod unit 150 is provided with a total of 14 rods and serves to mount a total of 2 rows * 7 interdental hygiene tools transferred by the transfer unit 160 to each rod.

In particular, the interdental hygiene tool in a heat-treated state by the heat treatment unit 140 is connected between the two floss tables constituting the dental floss, so that the two floss tables and the dental floss 210 have a ring shape. The collection rod part 150 serves to allow the interdental hygiene tools to be collected without indiscriminately disengaging by allowing such an annular shape to be fitted to fixed 2*7 rods.

The transfer unit 160 operates in a first direction, so that the dental floss molded in the first molding part 120 is transferred to the second molding part 130, and the molded product formed in the second molding part 130 is heat treated. It serves to be transferred to the part 140, and the interdental hygiene tool completed by heat treatment in the heat treatment part 140 is transferred to the collection rod part 150.

In addition, the transfer unit 160 operates in a second direction opposite to the above operation, and returns to the first molding part 120 to collect the dental floss molded in the first molding part 120, and the second molding part It returns to the second molding unit 130 to collect the molded product formed at 130, and serves to return to the heat treatment unit 140 to collect the interdental hygiene equipment that has been heat treated at the heat treatment unit 140. .

To this end, the transfer unit 160 is a first transfer unit for collecting the dental floss molded in the first molding unit 120, transferring it to the second molding unit 130, and being seated on the second molding unit 130 ( 161), a second transfer unit 163 for collecting the molded product formed in the second molding unit 130 and being transferred to the heat treatment unit 140 and seated on the heat treatment unit 140, and the heat treatment unit 140 The interdental hygiene tool completed by heat treatment at is collected and transferred to the collection rod unit 150 and includes a third transfer unit 165 for collecting in the collection rod unit 150.

The first transfer unit 161, the second transfer unit 163, and the third transfer unit 165 collect and transfer dental floss, molded products, and interdental hygiene items, respectively, but a suction unit for collection by a suction method, physical It can be implemented in any one of the mounting portions for lifting and collecting in a manner.

In addition, when the first upper mold 121 and the first lower mold 125 are released and opened, the operation in the first direction and the second direction may be performed with the second upper mold 131. It is performed when the closing of the second lower mold 135 is released and opened, and when the first heat treatment unit 141 and the second heat treatment unit 145 are spaced apart from each other and the heat treatment operation ends, the timings Are mutually synchronized.

On the other hand, the transfer unit 160 at the timing until the operation in the first direction is completed and the operation in the second direction starts again, the first transfer unit 161 is located between the second molding unit 130, The second transfer unit 163 is positioned between the heat treatment unit 140, and the third transfer unit 165 is maintained on the collection rod unit 150.

That is, there is no problem in forming in the first forming unit 120 and collecting in the collecting rod unit 150, but in the forming process in the second forming unit 130 and in the heat treatment in the heat treatment unit 140, the transfer unit The 160 is positioned between the second upper mold 131 and the second lower mold 135, and between the first heat treatment unit 141 and the second heat treatment unit 145.

In this case, the first transfer unit 161 is in a state in which the second upper mold 131 and the second lower mold 135 are closed so that interference with the molding process in the second molding unit 130 does not occur. It can be formed in a state having a corresponding intaglio shape.

In addition, the second transfer unit 163 is intaglio corresponding to a state in which the first heat treatment unit 141 and the second heat treatment unit 145 abut each other so that interference with the heat treatment process in the heat treatment unit 140 does not occur. It can be formed in a state having the shape of. This will be described in more detail later.

In the illustrated example, it is assumed that the first transfer unit 161 has an opening of a rectangular parallelepiped shape as a whole, but has a shape protruding only a certain portion from both sides.

That is, the shape of the first transfer unit 161 is the second upper mold 131 and the second lower mold so as not to interfere with the closing when the second upper mold 131 and the second lower mold 135 are closed. (135) can be formed to have an intaglio corresponding to the closed state.

On the other hand, the first transfer unit 161, its original role is to collect the dental floss molded in the first molding unit 120 and deliver it to the second molding unit 130.

To this end, the shape of the first transfer unit 161 has an intaglio corresponding to the closed state of the second upper mold 131 and the second lower mold 135, but the portion other than the intaglio is the first molding part 120 ) Can be formed to have a structure such as a suction unit, a mounting unit, etc. that can collect the molded article.

In the illustrated example, two parts protruding to the inside of the shape of the first transfer unit 161 are used to suck the molded product formed by the first molding part 120 from the first molding part 120 through an air suction method. It was assumed to operate as a suction part.

In both the case of operating as a suction unit or a mounting unit, the two parts protruding into the interior as described above are implemented so that the process of being retracted after protruding into the interior according to the design change is repeated, or the process of changing the protruding shape is repeated. It can be implemented, thereby avoiding interference and facilitating collection.

As described above, since the first transfer unit 161 is formed in an intaglio, interference with the operation of the second molding unit 130 can be eliminated, and at the same time, the molding formed by the operation of the first molding unit 120 It will be possible to transfer about.

In the above description, the first transfer unit 161 has been described, but this is an example for convenience of description, and may be applied to the second transfer unit 163.

That is, the molded article collected by the second transfer unit 163 also has a shape in which a total of 14 dental floss is not individually separated but is attached to one based on the runner. It can be implemented so as not to be significantly different from the transfer for the molded article collected by.

On the other hand, in the case of the third transfer unit 165, it should be implemented to collect a total of 14 interdental hygiene tools in a separately separated state by heat treatment by the heat treatment unit 140, for this purpose, a total of 14 air intakes. It may be implemented in a state in which a device or the like is provided.

Accordingly, by unifying the process of connecting the dental floss to the dental floss and the process of forming the interdental brush on the dental floss, it is possible to provide high-quality interdental hygiene equipment that does not provide discomfort to the user while promoting high productivity and economy.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and is generally used in the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Various modifications are possible by those skilled in the art, as well as these modifications should not be individually understood from the technical idea or perspective of the present invention.
