Description

Adhesive tape roll for cleaning and an apparatus for manufacturing adhesive tape roll for cleaning

The present disclosure relates to an adhesive tape roll for cleaning by winding an adhesive tape a plurality of times, and a manufacturing apparatus for manufacturing the same.

In general, it is difficult to clean foreign substances such as dust or hair due to static electricity. Accordingly, an adhesive tape roll cleaner that attaches and removes foreign substances using an adhesive is mainly used for cleaning such foreign substances.

The adhesive tape roll cleaner is provided with a tape roll coated with an adhesive on one surface. Accordingly, when the tape roll is brought into close contact with a place to be cleaned and rotated, foreign substances are attached to the surface of the tape roll and cleaning is performed.

The tape roll may have a structure in which an adhesive tape coated with an adhesive is laminated in multiple layers. Accordingly, when the adhesive force on the surface of the tape roll is lowered, a new adhesive tape can be used by peeling and removing one layer of the adhesive tape wound on the tape roll.

Such a tape roll may be manufactured by continuously winding an adhesive tape in the form of a film on which an adhesive is applied on one surface to a cylindrical paper tube or the like.

The present applicant has developed various devices for more effectively manufacturing a tape roll. For example, Patent Registration 10-1097242 (Name: Adhesive Tape Roll Winding Device for Cleaning, Publication Date: January 02, 2020) discloses a device developed by the present applicant and received a final registration decision. The adhesive tape continuously released from the supply roll is continuously wound on a cylindrical paper tube by forming a cutting line at a required position during the transfer process.

In the process of winding the adhesive tape on the paper tube, perforations are formed on the adhesive tape at regular intervals. Accordingly, the user can use it by easily removing the adhesive tape along the perforation line.

However, in the conventional structure, as the process of forming a perforation line on the continuously supplied adhesive tape and winding it on a paper tube is repeatedly performed, the process of decelerating and accelerating the movement speed of the adhesive tape inevitably occurs, resulting in a high defect rate and low productivity. there is.

In addition, the adhesive tape roll manufactured in this way has a disadvantage in that the interval between the perforated lines is not constant, and the position of the perforated line cannot be properly found, making it inconvenient to use.

Recently, the use of an adhesive tape roll is increasing for a more convenient life. Accordingly, improving and providing the technology for manufacturing the conventional adhesive tape roll can provide many advantages to the user.

An object of the present invention is to provide an adhesive tape roll for cleaning and an apparatus for manufacturing an adhesive tape roll for cleaning, which can minimize the occurrence of defects due to fluctuations in the transport speed of the adhesive sheet by effectively forming a perforation line while transporting the adhesive sheet at a constant speed.

An object of the present invention is to provide an adhesive tape roll for cleaning and an apparatus for manufacturing an adhesive tape roll for cleaning, so that perforations can be formed on the adhesive sheet at regular intervals.

An object of the present invention is to provide an adhesive tape roll for cleaning and an apparatus for manufacturing an adhesive tape roll for cleaning capable of forming a perforation line at a predetermined position.

An object of the present invention is to provide an adhesive tape roll for cleaning and an apparatus for manufacturing an adhesive tape roll for cleaning in which the perforation line formation position can be easily confirmed.

The cut-out portion is a lower roller supporting and supporting the pressure-sensitive adhesive sheet under the pressure-sensitive adhesive sheet, is disposed above the lower roller, and a blade for forming a perforation line is installed along the axial direction to form a perforation line in the width direction on the pressure-sensitive adhesive sheet passing through the lower roller It may include an upper roller, an upper roller driving unit for rotating the upper roller, and a regulating unit for regulating the position of the cutting edge of the knife for the adhesive sheet.

The regulating unit controls the rotation speed of the lower roller driving unit according to an output signal of a detection sensor for detecting the recognition mark formed on the adhesive sheet, a speed sensor for detecting the rotation speed of the upper roller, and the detection sensor and the speed sensor It may include a speed control unit for matching the position of the recognition mark and the position of the blade.

The recognition mark is formed on at least one tip of the adhesive sheet, and the detection sensor is spaced apart from the lower roller and disposed on the tip of the adhesive sheet to detect the recognition mark formed on the tip of the adhesive sheet.

The length of the major axis of the recognition mark may be 4 to 5 times the length of the minor axis.

The speed control unit determines that the blade is lower roller top dead center according to the time at which the recognition mark reaches the lower roller top dead center and the upper roller rotation speed at the time of detection of the recognition mark formed on the adhesive sheet according to the moving speed of the adhesive sheet It may be a structure for controlling the rotational speed of the upper roller by comparing the time to reach.

The pressure-sensitive adhesive tape roll of this embodiment may include a cylindrical paper tube, an adhesive tape wound on the paper tube a plurality of times and installed, an adhesive is applied to the surface, and perforated lines formed in the width direction at regular intervals.

The adhesive tape may include a recognition mark formed at the same position as the perforation line on at least one distal end along the perforation line to indicate the position of the perforation line.

A design of a single color may be printed on the surface of the adhesive tape, and the recognition mark may be formed in the same color as the design.

As described above, according to the present embodiment, a perforation line can be formed while continuously transferring a large amount of adhesive sheet fabric at a constant speed. Accordingly, in the process of forming the perforated line, deceleration or acceleration of the pressure-sensitive adhesive sheet transfer speed is not unnecessary or generated, so that the perforated line can be formed more accurately and productivity can be maximized.

It is possible to form perforated lines at precise intervals on the adhesive sheet, making it possible to manufacture more sophisticated products with uniform perforation line formation intervals. It is easier to use the adhesive tape roll because the intervals of the perforated lines are constant.

In addition, the perforated line can be formed only at the position where the recognition mark is formed, so that the perforated line and the recognition mark do not deviate, and a high-quality product that is always consistent can be manufactured.

In addition, the user can easily check the position of the perforated line through the recognition mark formed on the adhesive sheet, thereby reducing the hassle of finding the perforated line and cutting the adhesive sheet more conveniently.

In addition, even if the recognition mark is formed in the same color as the design printed on the adhesive sheet, the position of the recognition mark can be accurately detected to form a perforation line. Accordingly, it is possible to increase the productivity and lower the cost by omitting the additional process of using a different color for the recognition mark.

As shown, the manufacturing apparatus 100 of this embodiment is provided in the frame 10 constituting the framework of the facility, and the supply unit 20 for continuously supplying the adhesive sheet (S), forming a perforation line on the adhesive sheet (S) The perforated portion 30, the winding portion 40 for rewinding the adhesive sheet S with the perforated line L, and the pressure roller 44 for attaching the adhesive sheet S to the winding shaft 42 of the winding portion 40 ) may be included.

Accordingly, the perforated lines L may be continuously formed at regular intervals while continuously transferring a large amount of the adhesive sheet S fabric at a constant speed through the present manufacturing apparatus 100 .

In the case of the conventional apparatus, a series of processes of forming a perforation line on the adhesive sheet, winding it on a paper tube to a certain length, and then cutting are performed, so the process of decelerating and accelerating the transport speed of the adhesive sheet was repeated. In the case of this embodiment, only the process of forming the perforated line L on the adhesive sheet S can be performed, so that deceleration or acceleration of the transport speed of the adhesive sheet S does not occur. Therefore, it is possible to form the perforation line (L) more accurately, it is possible to maximize productivity.

The supply unit 20 continuously releases the adhesive sheet (S) from the coil on which the adhesive sheet (S) is wound and supplies it. The supply unit 20 may include an unwinding shaft 22 installed on the frame 10 to support the coil, and a driving motor (not shown) for rotating the unwinding shaft. Accordingly, it is possible to continuously supply the adhesive sheet S from the coil to the cutout 30 while fixing the coil to the unwinding shaft 22 and rotating the unwinding shaft by operating the driving motor.

The winding portion 40 is disposed at the rear end of the cutout 30 and winds the pressure-sensitive adhesive sheet S having the cutout line L formed thereon through the cutout 30 into a cylindrical coil again. The adhesive sheet (S) coil wound in the winding unit 40 may be transferred to a post-process, wound to a predetermined length on a paper tube, and then divided into set sizes to manufacture an adhesive tape roll product.

The winding unit 40 is installed on the frame 10 and includes a winding shaft 42 on which a core on which the adhesive sheet S is wound is installed, and a driving motor (not shown) for rotating the winding shaft 42 . can Accordingly, the adhesive sheet S is continuously wound on the core of the take-up shaft 42 while fixing the adhesive sheet S to the core of the take-up shaft 42 and rotating the take-up shaft 42 by operating the driving motor. there is.

A pressing roller 44 is provided adjacent to the winding shaft 42 of the winding unit 40 . The pressure roller 44 is installed movably horizontally on the frame 10 . The pressure roller 40 is moved toward the take-up shaft 42 to press and adhere the tip of the adhesive sheet S to the core of the take-up shaft 42 . The pressure roller 44 moves to the take-up shaft 42 and presses and adheres the tip of the pressure-sensitive adhesive sheet S lowered by the pressure roller 44 to the core of the take-up shaft 42 .

The pressure roller 44 is horizontally moved outward from the take-up shaft 42 as the diameter of the coil increases while the adhesive sheet S is continuously wound on the take-up shaft 42 . Accordingly, the pressure-sensitive adhesive sheet S released from the supply unit 20 can be accurately rewound into a coil by continuously pressing and closely adhering to the winding shaft by the pressure roller 44 to the end.

Here, the adhesive sheet (S) may mean a sheet fabric in which at least one adhesive portion (P) formed to fit the size of the adhesive tape roll product is continuously arranged at intervals along the width direction. The adhesive portion P may mean a portion to which an adhesive is applied. That is, the adhesive sheet (S) can be understood as a large-sized fabric before being divided into a plurality of adhesive tape roll products. Hereinafter, for clear distinction, the subunit adhesive sheet (S) divided by cutting between the adhesive parts (P) in the adhesive sheet (S), which is the original fabric, is referred to as an adhesive tape (see T in FIG. 4 ).

The pressure-sensitive adhesive sheet (S) may be supplied to the next process after the perforated line (L) is continuously formed through the device. And after being wound to a predetermined length on a paper tube in a later process, it may be finally cut between the adhesive portions P to manufacture a plurality of adhesive tapes T.

This embodiment has a structure in which the perforated line (L) is formed at the exact position set at regular intervals on the pressure-sensitive adhesive sheet (S), which is an intermediate material.

To this end, the cutout 30 may be disposed at the rear end of the supply unit 20 to form a cutout line L in the width direction according to the position of the recognition mark of the adhesive sheet S.

The cut-out portion 30 of this embodiment is disposed above the lower roller 32 and the lower roller 32 for supporting and supporting the pressure-sensitive adhesive sheet S in the lower portion of the pressure-sensitive adhesive sheet S, and the perforation line L is formed along the axial direction. The upper roller 34 for forming a perforated line L in the width direction in the adhesive sheet S passing through the lower roller 32 by installing a blade 36 for The driving unit 38 and the pressure-sensitive adhesive sheet (S) may include a regulating unit for regulating the perforated line (L) formation position of the blade 36.

It is possible to accurately form the perforated line (L) at a predetermined position of the pressure-sensitive adhesive sheet (S) by the regulating unit.

The cut-out portion 30 is a blade 36 installed on the upper roller 34 while the upper roller 34 and the lower roller 32 arranged vertically with the adhesive sheet S interposed therebetween, and the adhesive sheet (S) A perforated line (L) is formed in the width direction.

1, a plurality of guide rollers 39 for adhering the adhesive sheet S to the lower roller 32 at the front and rear ends of the lower roller 32 along the moving direction of the adhesive sheet S. can be placed. Each guide roller 39 is rotatably installed on the frame 10 to support the conveyed adhesive sheet S in a horizontal state in a flat state.

The adhesive sheet (S) released from the coil passes while wrapping the upper side of the lower roller (32) by a plurality of guide rollers (39) on both sides of the lower roller (32). Accordingly, the pressure-sensitive adhesive sheet (S) can be moved while sufficiently in contact with the lower roller (32). The guide roller 39 applies tension to the pressure-sensitive adhesive sheet (S) to move the pressure-sensitive adhesive sheet (S) in a taut state. The installation position or number of the guide rollers 39 may be variously modified.

The upper roller 34 is disposed above the lower roller 32 and extends long along the axial direction of the lower roller 32 . The upper roller 34 is installed to protrude the blade 36 for forming the perforated line (L) on the outer surface. A plurality of blades 36 may be arranged at intervals along the circumferential direction of the upper roller 34 . In the case of this embodiment, the two blades 36 are arranged and installed at 180 degree intervals. Each blade 36 has the same structure and extends long along the axial direction of the upper roller 34 . Accordingly, the blade 36 may be disposed in the width direction of the adhesive sheet S to form a perforation line L on the adhesive sheet S in the width direction according to the rotation of the upper roller 34 .

The blade 36 may have, for example, a sawtooth-like structure to form a perforated line L in the form of a dotted line. Accordingly, when the upper roller 34 is rotated by the driving of the driving unit 38 , the cutting line L is formed at regular intervals in the adhesive sheet S passing through the lower roller 32 by the blade 36 . The adhesive sheet S on which the perforated line L is formed while passing through the cutout 30 is wound on the winding shaft 42 of the winding portion 40 via the guide roller 39 .

When the perforated line L is formed by the perforated portion 30, the control unit controls the positions of the adhesive sheet S and the blade 36 to precisely form the perforated line L at the set position of the pressure-sensitive adhesive sheet (S).

The regulation part of this embodiment includes a detection sensor 52 for detecting the recognition mark 51 formed on the adhesive sheet S, a speed sensor 54 for detecting the rotational speed of the upper roller 34, a detection sensor 52 and It may include a speed control unit 50 for controlling the rotation speed of the upper roller driving unit 38 according to the output signal of the speed sensor 54 to match the position of the recognition mark 51 and the position of the blade 36 .

The recognition mark 51 marks the position of the perforated line (L) and guides the position of the perforated (L) on the finally manufactured adhesive tape roll product. In this embodiment, the recognition mark 51 may be formed on both ends of the adhesive sheet (S). The recognition mark 51 may be formed in a non-adhesive part between the adhesive part P and the adhesive part P in addition to the front end of the adhesive sheet S. Accordingly, when the adhesive tape is manufactured by dividing between the adhesive portions P of the adhesive sheet S, a recognition mark 51 may be formed at the tip of each adhesive tape. The structure of such an adhesive tape will be described later.

The recognition mark 51 may be a pattern of a predetermined shape printed in a color different from the color of the adhesive sheet (S). For example, the recognition mark 51 may be formed in a color other than white with respect to the white adhesive sheet S. Accordingly, the detection sensor 52 can easily identify and detect the recognition mark 51 . The shape of the recognition mark 51 may be variously modified if it can be detected by the detection sensor 52 .

In addition, the pressure-sensitive adhesive sheet (S) is printed on the surface of a single color design, the recognition mark 51 may be formed in the same color as the design. A design can be understood as expressing various patterns, shapes, drawings, letters, shapes, etc. The pattern may be formed on the adhesive portion P. Accordingly, it can be formed by printing the design and the recognition mark 51 on the original fabric of the adhesive sheet S at the same time.

Accordingly, it is possible to reduce the effort of separately forming the recognition mark 51 in a color different from that of the design.

The detection sensor 52 may identify the presence or absence of the recognition mark 51 . For example, the detection sensor 52 may have a structure that detects the recognition mark 51 by recognizing a difference in contrast between the front end of the adhesive sheet S and the recognition mark 51 . The detection sensor 52 may have various structures other than the contrast difference detection structure.

The detection sensor 52 may be spaced apart from the lower roller 32 to match the position of the recognition mark 51 formed on the tip of the adhesive sheet S, and may be disposed on the tip of the adhesive sheet S. Accordingly, the recognition mark 51 formed on the front end of the adhesive sheet S of the adhesive sheet S in the process of moving the adhesive sheet S may be detected by the detection sensor 52 .

The recognition mark 51 is formed on both the non-adhesive part and the other tip between the adhesive part P along the width direction of the adhesive sheet S in addition to the tip of the adhesive sheet S corresponding to the detection sensor 52 . Accordingly, when the perforated line L is formed at the position of the recognition mark 51 in the cutout 30 according to the detection signal of the detection sensor 52 , on all the recognition marks 51 in the width direction of the adhesive sheet S A perforated line L may be formed.

The recognition mark 51 at the tip of the adhesive sheet S detected by the detection sensor 52 may have a rectangular shape extending for easier detection. In this way, by extending the length of the recognition mark 51 sufficiently long, it is possible to minimize the recognition error by the detection sensor (52).

3, in the present embodiment, the recognition mark 51 may have a major axis length (A) of 4 to 5 times the minor axis length (B).

If the major axis length (A) is less than 4 times the minor axis length (B), the detection sensor 52 may not properly recognize the color of the recognition mark 51 if the color is light. When the major axis length (A) exceeds 5 times the minor axis length (B), the recognition effect does not particularly increase, and the length of the tip end of the adhesive sheet (S) must also be increased, which may result in an increase in cost.

Moreover, an adhesive is applied to the tip of the adhesive sheet (S) with a predetermined width for cutting the tip. interfere Accordingly, when the recognition mark 51 is formed in the ratio of the above-described length, the detection sensor 52 can accurately detect the recognition mark 51 without being affected by the pressure-sensitive adhesive formation region (D).

Accordingly, the detection effect by the detection sensor 52 can be enhanced even when the color of the recognition mark 51 is pale, such as pastel tone, and is not clearly distinguished from the color of the tip of the adhesive sheet S.

In addition, since the detection sensor 52 can properly detect the recognition mark 51, even when the color of the pattern formed on the adhesive part is light, the product is printed in one color without separately printing the recognition mark 51 in another color. can be manufactured.

The speed sensor 54 may, for example, be installed on the rotation shaft of the upper roller 34 to detect the rotation speed of the upper roller 34 through the speed of the rotation shaft. The speed sensor 54 is sufficient as long as it can detect the rotation speed of the upper roller 34, and its installation position or structure can be variously modified.

The speed control unit 50 receives the output value for the movement speed of the adhesive sheet S, the recognition mark 51 detection signal, and the rotation speed of the upper roller 34, and compares and calculates them.

The speed control unit 50 determines the time at which the recognition mark 51 formed on the pressure-sensitive adhesive sheet S is detected according to the moving speed of the pressure-sensitive adhesive sheet S. According to the rotation speed of the upper roller 34, the time for the blade 36 to reach top dead center of the lower roller 32 is compared and calculated to control the rotation speed of the upper roller 34.

For example, at the time of detection of the recognition mark 51 , the blade 36 of the upper roller 34 reaches top dead center of the lower roller 32 rather than the time when the recognition mark 51 reaches top dead center of the lower roller 32 . When the time is late, the rotation speed of the upper roller 34 is increased by controlling the upper roller driving unit 38 .

Accordingly, as the upper roller 34 rotates rapidly, the blade 36 reaches top dead center of the lower roller 32 more quickly, and the position of the recognition mark 51 of the adhesive sheet S and the position of the blade 36 coincide will do

Conversely, the time for the blade 36 of the upper roller 34 to reach TDC of the lower roller 32 rather than the time for the recognition mark 51 to reach TDC of the lower roller 32 at the time of detection of the recognition mark 51 In this fast case, the rotation speed of the upper roller 34 is lowered by controlling the upper roller driving unit 38 .

Accordingly, as the upper roller 34 rotates slowly, the blade 36 reaches the top dead center of the lower roller 32 later, and the position of the recognition mark 51 of the adhesive sheet S matches the position of the blade 36 will do

In this way, the rotation speed of the upper roller 34 is controlled by the speed control unit 50 so that the blade 36 accurately forms the perforation line L in the width direction of the adhesive sheet S at the recognition mark 51 position. be able to

In addition, in this embodiment, the infeed 60 and the outfeed 70 for matching the transport speed of the adhesive sheet S at the front end and the rear end of the cutout 30 along the transport direction of the adhesive sheet S, respectively. may be further provided.

The in-feed 60 and the out-feed 70 may include driving rolls 62 and 72 disposed vertically and driven rolls 64 and 74 selectively pressed into contact with the driving rolls, respectively.

The pressure-sensitive adhesive sheet S released from the supply unit 20 according to the operation of the driving roll 62 of the infeed 60 is engaged between the driving roll 62 and the driven roll 64 and moved at a constant speed to move the cut-out portion 30 ) can be supplied.

According to the operation of the driving roll 72 of the outfeed 70, the adhesive sheet S that has passed through the cutout 30 is engaged between the driving roll 72 and the driven roll 74 and can be pulled and moved at a constant speed.

In this way, the infeed 60 pushes the adhesive sheet S to the cutout 30 with the cutout 30 interposed therebetween, and the outfeed 70 pulls the adhesive sheet S. Accordingly, the pressure-sensitive adhesive sheet (S) can be cut while passing the cut-out portion 30 at a constant speed.

Accordingly, the position of the recognition mark 51 of the adhesive sheet S and the position of the blade 36 of the upper roller 34 are more precisely matched, and the perforation line L can be formed at the position of the recognition mark 51 .

It may include the formed adhesive tape (T).

Here, the adhesive tape T may be formed by cutting the adhesive sheet S on which the perforated line L is formed according to the present embodiment for each adhesive portion P.

A recognition mark 51 is formed between both ends of the adhesive sheet (S) and the adhesive part (P) and the adhesive part (P). The recognition mark 51 is provided.

Accordingly, the adhesive tape T of this embodiment may include a recognition mark 51 formed at the same position as the perforation line L at at least one distal end along the perforation line L to indicate the position of the perforation line L.

Accordingly, the user can easily know the position of the perforation line (L) by checking the recognition mark 51 formed on the adhesive tape (T) without having to find the position of the perforation line (L), and the adhesive tape used along the perforation line (L) can be used. can be easily removed.

In addition, the adhesive tape (T) may be formed by further printing a single color design on the adhesive portion (P).

The design may be formed in the same color as the recognition mark 51 . In this embodiment, the design and the recognition mark 51 may be formed by printing in a single color. In this way, by forming the recognition mark 51 on the adhesive tape T and forming a predetermined pattern on the adhesive portion P, the marketability of the adhesive tape roll product can be improved.
