Description

Screen Rotator for Advertising {Rotating System for a poster screen}

The present invention relates to an advertisement rotating device, and more particularly, to an advertisement screen rotating device designed to display various advertisement contents by sequentially changing contents printed on a surface by rotating a screen.

In general, advertisements are installed in places where many people, such as subways, public offices, express bus terminals, and stations, enter or leave the city to inform specific information to a large number of unspecified people. Usually, these advertisements come in various forms, such as billboards, monitors, posters and signs. The advertisements are different in production cost and installation conditions depending on the form. As an example of such advertisements, a billboard-type advertisement is often installed for the purpose of providing decorativeness to a relatively narrow space and delivering necessary contents, which can be commonly seen in subways or stations. However, these advertisements are 3 ~ 5m in size, and the advertising content required for polyethylene film is usually printed, attached to the front, and the lighting is installed inside.

As such, the interstitial advertisements do not cause visual interest in the advertisement itself because they are static advertisements, and thus there is a problem in that the advertisement effect decreases. Therefore, there are dynamic advertisements that display advertisement contents such as a monitor or a display board, but this requires a lot of cost and a lot of constraints due to securing an installation space.

Therefore, the present invention is a design devised to solve the above problems.

The purpose of the present invention is to provide a screen rotating device for advertising that can enhance the advertising effect by moving the advertising content to bring visual interest to the advertisement itself so that the viewer can see a wider range of advertising content so as not to feel unwell. have.

Advertisement screen rotating apparatus according to the present invention and the bracket is coupled to each of the upper, lower, left and right corners in the frame so as to be spaced apart a certain distance from each other;

Respective rollers wound or wound around an advertisement screen rotatably installed between the upper and lower brackets;

Rotating means for rotating the roller (30);

Clutch means for connecting or disconnecting power and rotatably supporting the rollers when the rollers are rotated clockwise and counterclockwise;

The roller rotated by the rotating means may be implemented as a brake means for preventing the screen loosening phenomenon due to rotational inertia.

Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail according to the accompanying drawings.

1 is a perspective view showing the main portion of the sign of the present invention cut, Figure 2 is an excerpt perspective view showing a bracket and a roller 30 installed inside the screen rotating apparatus according to the present invention, reference numeral 10 in the drawings Is an advertisement assembly frame, 20 is a bracket that is coupled within the frame, 30 is a roller 30 that is rotatably coupled on the bracket so that the screen on which the advertisement content is printed can be wound or rolled up, and 40 is the roller. Drive means for driving, 60 is a brake means for providing a constant resistance to the roller so that the screen is further discharged while being rotated by the rotational inertia when the roller 30 is rotated and stopped.

The above-described frame 10 constitutes an exterior of an advertisement, and has a fixing flange for fixing itself on one side thereof. The bracket 20 is fixed to the inside of the frame by bolts and is fixed to each of the upper, lower, left and right corners of the frame 10. Each bracket 20 fixed to the upper and lower sides fastens the upper and lower brackets 20 to each other through a plurality of connecting rods 12 on the surface thereof to provide mutual reinforcement. On the surface of the bracket 20, a plurality of large and small through holes 13 and slots 14 are provided. The through hole 13 is rotatably coupled to the roller 30 is wound or wound around the screen (SR) is printed advertising content. The guide roller 14a is coupled to the slot 14 so as to be slidably moved along the slot, and the guide roller 14a exerts a tension force to the outside of the frame 10 by the tension spring s1. One end of the spring s1 is coupled to the guide roller 14a and the other end of the spring s1 is coupled to the connecting rod 12. In addition, when the rollers are replaced, the guide rollers 14a may move the guide rollers 14a to the left to secure a space for the rollers to enter and exit. In addition, since the screen SR wound or wound on the roller 30 increases or decreases in volume depending on the wound state, the screen is not positioned parallel to the frame in front of the frame, but the guide roller 14a surrounds the guide roller. As a result, the screen SR is positioned in parallel with the frame 10.

The rollers 30 described above are rotated by driving means independently coupled to each other. As an example of the driving means of the roller, as shown in FIG. 2 or FIG. 4, a driving motor 40 which is rotated by a power source is fastened to the bracket 10 by bolts. The sun gear 41 is fastened to the motor shaft of the drive motor 40, and the sun gear meshes with the planetary gear 51. The planetary gear 51 is coupled to the clutch means 50 for selectively transmitting or interrupting power to the roller.

The clutch means 50 should be free to rotate so that the roller 30 on the other side of the roller 30 is rotated while the screen is wound while the roller is rotated. The two rollers alternately rotate to move the screen from side to side or right to left.

Therefore, when one of the rollers 30 rotates, power must be cut off so that the other side must be idling so that the screen can be alternately transferred from side to side. Thus clutch means 50 must be included to connect and disconnect power.

One example of the clutch means includes a clutch housing 51b having a through hole 51a therein and bolted to the bracket 20 as shown in FIGS. 2, 4 and 5;

A copper 31b coupled to one end of the roller 30 and having a clutch groove 31a on the surface thereof;

A shaft hole 54 inserted into the through hole 51 a of the clutch housing 51 b together with a bearing b1 to be rotatably fastened and penetrated therein, and formed to penetrate from the circumferential surface toward the shaft hole 54. A driven shaft 55 including a helical groove 54b and having a planetary gear 51 engaged with the sun gear 41 of the driving motor 40;

An end portion includes a clutch pin 52a inserted into the clutch groove 31a, and includes a sliding pin 52b coupled to be positioned in the spiral groove 54b, and is inserted into the driven shaft 55. It may be implemented as a clutch shaft 53 that is rotatably fastened.

As an example of the action on the clutch means according to the above configuration, as shown in FIGS. 4 and 5, the power is transmitted to the driven shaft 55 to rotate. In this case, the clutch means 50 is formed symmetrically on the left and right rollers, respectively, and describes the process of moving the screen SR from left to right.

When the sun gear 41 rotates counterclockwise, the planetary gear 51 rotates clockwise while the driven shaft 55 also rotates clockwise. At this time, the sliding pin 52b inserted into the spiral groove 54b of the driven shaft 55 slides on the surface of the spiral groove 54b and moves upwardly of the spiral groove 54b. Therefore, the sliding pin 52b is lifted to the upper side of the spiral groove 54b to act to lift the clutch shaft 53. Therefore, since the clutch pin 52a coupled to the end of the shaft 53 is inserted into the clutch groove 31a of the lower side 31b, power is transmitted to the lower side 31b by the clutch pin 52a and the lower side The roller 30 coupled to the copper 31b rotates. Therefore, the screen SR is wound around the circumferential surface of the roller so that the screen is moved from left to right.

In this way, the screen SR is moved, and the screen is required to control the driving and stopping of the driving motor 40 by displaying the print content while repeating the transfer and stop operation by a predetermined period. Therefore, as a means for repeatedly moving and stopping the screen, an optical sensor (not shown) is attached to the frame 10, and one screen is preferably displayed at a predetermined interval on the back of the screen. It can be realized by attaching a reflective tape at frame intervals. When the reflective tape reaches the optical sensor position while the roller 30 is rotated by the rotation of the driving motor 40, the light emitted from the optical sensor is reflected by the reflective tape and the incident signal is input again. When detected, the signal is transmitted to the microcomputer (not shown) as an electrical signal. The microcomputer is cut off the power supplied to the drive motor 40 in a programmed process for a predetermined time.

In addition, after a certain time, the power is supplied again by the microcomputer to drive the driving motor. In addition, the signal detected by the optical sensor counts the number of detections in the microcomputer, and when the number of times is set, the power is supplied to the opposite driving motor to rotate the opposite driving motor.

In this case, the unwinding roller 30 stops without the driving motor operating. The roller 30 rotates counterclockwise by the screen and its rotational force is applied to the spiral groove 52b of the driven shaft 55. As the sliding pin 52b positioned is lowered along the surface, the clutch pin 52a is released from the clutch groove 31a of the roller 30 so that the roller 30 is provided on the clutch housing 51b together with the lower flank 31b. The screen SR is released while rotating.

However, in this process, the roller 30 on the opposite side of the clutch means may be fastened using a conventional bearing, but in this case, the roller 30 is rotated by the rotational inertia when the roller 30 stops rotating. The further rotation without stopping immediately can cause the screen to sag or hang.

In order to compensate for the screen sagging phenomenon, the roller 30 further includes a brake means for giving a constant resistance.

As an example of the brake means, referring to FIGS. 6 and 7, FIGS. 6 and 7 are examples of brake means for providing a resistance force when the screen SR is wound or rotated on the wound roller 30 according to the present invention. A cross-sectional and exploded perspective view of an example.

The brake means includes a bearing cover 72 having a through hole 70 having a bearing b2 therein and bolted to a through hole 13 on the bracket 20;

A support shaft 74 having a Y-shaped connector 74a at one end thereof and inserted into the through hole 70;

A pulley (73) having a unidirectional clutch bearing (73a) in the shaft hole engaged with the support shaft (74) and coupled to an end of the support shaft (74);

A belt v placed on the pulley 73 and the bracket 20 adjacent to the belt fixing rod 78 and fixed between the belt fixing rod 78 and the pulley 73;

An upper corner 76 fastened to an end of the roller 30 and having a shaft hole 75 into which a spring s2 is inserted;

A groove is formed in the end to which the E-ring (e) is fastened so as not to retreat through the shaft hole (75) of the upper flange (76), and the stepped portion where the end of the spring (s2) is caught, and the Y-shaped connector (74a) And a connecting shaft 77 including a corresponding connector 77a.

The operation by the brake means configured in this way will be described.

First, in order to mount the roller 30 to the roller rotating device, the vertical position is set so that the clutch pin 52a is coupled to the lower portion of the roller 30, that is, the clutch groove 31a, and the opposite side thereof has the connecting shaft 77 downward. When pressed, the connecting shaft 77 is reduced in length while being inserted into the upper flap 76 while overcoming the elasticity of the spring s2. Therefore, in this state, the end of the connecting shaft 77 is positioned to engage with the connector 74a of the supporting shaft 74, and then the pressure is removed, and the connecting shaft 77 is elastically acting toward the supporting shaft 74. The connectors 74a and 77a mesh with each other. Therefore, since the connecting shaft 77 and the support shaft 74 are connected through the Y-shaped connector 74a, the support shaft 74 rotates while supporting the roller 30 when the driving motor 40 is rotated. At this time, the roller 30 is rotated by the belt v fixed between the pulley 73 and the belt fixing rod 78 while the roller 30 is rotated, thereby receiving s resistance according to the rotation released. Therefore, the roller 30 is subject to rotational resistance by the frictional resistance of the belt, thereby preventing the loosening of the screen SR due to the rotational inertia of the roller 30. In addition, the connecting shaft 77 is very convenient even when each roller 30 is easily separated or exchanged from the bracket 20.

The pulley 73 is turned by the one-way clutch bearing 73a coupled to the shaft hole when the roller 30 winds up the screen, and the one-way clutch bearing 73a when the rolled screen is released from the roller. The pulley 73 rotates due to the rotation of the pulley 73 while overcoming the frictional resistance of the belt v.

As another embodiment of the brake means, as shown in Figs. 2 and 4, the clutch shaft 53 is further extended to engage the pulley 73 on its axis, and the bracket 20 in a position adjacent to the driven shaft pulley 73 is shown. Similarly, the belt fixing bar 78 may be attached to the belt fixing rod 78 and the belt v may be fixed to the end of the belt fixing rod 78, and then the belt may be wound around the pulley 73 to be connected.

In addition, since the screen SR is placed on the front surface of the guide roller 14a, the screen SR can be maintained in a more taut state by the tension of the spring s1 pulling on both sides.

As described above, according to the present invention, not only is it advantageous to provide various information by sequentially showing advertisement contents, but also the advertisement contents can be increased or decreased according to the degree of curling of the rollers, and the viewer is visually interested by moving the screen. It can raise the advertising effect will be improved.
