Description

A screen drive device for advertising billboards {A Screen drive for advertising board}

The present invention relates to a screen billboard, and in particular, the advertising surface of the screen billboard is made of film without using acrylic, resin fabric, iron plate, etc., and the advertising device is built in rollers mounted inside the signboard, and the driving device By rotating the rollers by changing the different advertising surface according to a certain time to the outside, and to the signboard to be easily replaced with the new advertising surface film.

The general form of the signboard is divided into the same type and the floating type in relation to the change of advertisement surface of the sign.

In the case of the floating signboard, the advertisement surface is produced by cutting one by one, so the expression of various advertisement surfaces is limited. Whenever the user of a building with a signboard is changed, there is a wasteful factor due to the removal and the installation of a new signboard and the manufacture and installation of a new signboard. It appeared to inhibit aesthetics.

On the other hand, the same type of signboards are usually made in advance of screen cuts of several cuts, and then rolled around the rollers in a vertical direction to display the advertisements expressed on the screen. The screen is made up of several advertisements, and the display is displayed intermittently or continuously in accordance with the rotation of the drum roller, so that a single signage can display various advertisements. It is limitedly used for advertisements in places with narrow rotation intervals such as advertisements or subway stations.

The screen used here is made of cloth or vinyl cloth which can transmit light, and the screen drive device includes a speed-deceleration motor, a screen drum and a roller, a belt and a chain that transmits power from the motor to the drum and the roller, and position detection. Control device including a device and a timer.

In the driving method of the screen, if the screen, the motor, and the control device are properly placed in the frame and the power is turned on, the power of the motor is transmitted to the drum and the roller through the belt or the chain according to the rotation of the motor, and the rotation of the drum starts. . As the drum rotates, the screen is wound on the drum with one direction. In this process, when the drum stops rotating, the corresponding surface of the screen is immediately displayed on the advertisement surface, and when the drum is rotated again, the other advertisement surface comes out. By controlling the rotation of the drum in this way it is possible to select and adjust the frequency and timing of the change of the advertising surface. In general, the method of controlling the cut of the advertisement surface uses a method of changing the advertisement surface by moving the screen by stopping the motor on a predetermined track when the position of the screen is changed by using a detection element, and moving the screen again after the waiting time through the timer. .

However, such a screen control device of the same type signage is difficult to precise position control when the screen is wound around the drum. This is due to the flexibility of the screen, which is related to the minimum properties of winding and unwinding the drum, so it is difficult to wind and unwind without the flexibility of the screen. Therefore, the flexibility of the screen acts as an obstacle to the winding and unwinding, and there is a limit to precisely controlling it through the drum. The corresponding cut on the face appears as a wrinkle or fold.

Such conventional iso-type signboards have the characteristics that various advertisement surface can be changed by winding the screen through the drum roller, but it is difficult to produce a long advertising surface with the problems such as wrinkles or double folding that appear in the flexibility of the screen. It worked as a problem. This appeared to be a limitation that can not provide a good advertising surface, it was difficult to apply due to the low operating reliability of the screen.

Therefore, an object of the present invention is to provide a screen drive device of the same type signage that can stabilize the dynamic movement of the screen advertising surface, which is a component of the same type signage, and give the reliability of the operation of the position control of the advertising surface.

As the same type signboard of the present invention has a horizontally arranged screen surface, the front window has a horizontal orientation, drum rollers are disposed at both sides thereof, and a driving motor is located at the center thereof, so that the force balance and the screen are pulled out. It was designed to wind while giving.

The main part of the case (1) and the front window (2) is located horizontally in the case (1), and the two sides of the case (1) are divided into a feeding roller (3) and a winding roller (4), respectively, the surface contact The drum roller 5 is disposed on the case 1 in the longitudinal axis, and the winding roller 4 is a tension spring 7 whose rotation center is changed according to the winding thickness of the screen 6, and the shaft 8 is Supported by the case (1), the feeding roller 3 has a pulley (9) and the motor 10 is located in the center of the case 1 is configured to transfer power to each feeding roller (3), The surface of the feeding roller 3 in contact with the winding roller 4 is configured by arranging the gripper 11 supported by the spring 7 in a circumferential manner, and the screen 6 includes the gripper of the feeding roller 3. 11 is formed by the engaging groove 12 is formed symmetrically with the distance between each gap of the winding and unwinding to the drum roller (5) of both sides Is a lock portion.

The screen 6 is made in accordance with the size of the signboard's width front window 2 like a film for a projector, and coincides with the gripper 11 of the feeding roller 3 of the drum roller 5 located on both sides of the case 1. Drilling the hooking groove 12 to the surface is deposited by printing or printing a color adhesive sheet to produce an advertising surface for illumination in one cut and then fixed to fit the gripper 11 of the feeding roller (3). At this time, while fixing the winding roller (4), while engaging the engaging groove 12 and the gripper (11), winding the advertising surface by one cut on the winding roller (4) and connecting the other advertising surface as above, the required amount of advertising surface After winding the screen, the last screen is connected to the opposite drum roller (5) in the same way to wrap the screen (6) to the drum roller (5), where there is no need to connect the screen (6) by one cut. This is to remove the advertising surface to be connected to the new advertising surface screen (6) to the portion.

At this time, a position-sensitive element capable of controlling the motor 10 embedded in the case 1 is provided at the lower end of the advertisement surface screen 6 of each cut, and a detection element is installed at the lower end of the feeding roller 3 inside the signboard. As the screen 6 passes, it is manufactured to control the driving of the motor 10.

Motor 10, drum roller 5, and other power transmission components built into the case 1 are each arranged with a group of drum rollers 5 on both sides of the case 1, and an advertisement surface screen at the front. (6) the feeding roller (3) is arranged so that the advertisement surface screen is rotated in a constant track without being pulled out and pulled, and the winding roller (4) which winds, stores and unwinds the advertisement surface screen (6) at the rear thereof. Install. The winding rollers 4 are supported by the tension springs 7 so as to always be in surface contact with the feeding rollers 3 so that the screens 6 move along them, and pass between the rollers 3 and 4. And then rolled out the advertisement surface screen (6) and also serves to release when rotating on the contrary.

When the feeding roller 3 and the winding roller 4 rotate in close contact with each other, the gripper 11 protruding from both ends of the feeding roller 3 contracts the spring 7 only when the winding roller 4 contacts and contacts. Rotate in while leaving the rest as it is. These grippers 11 are arranged in plural numbers symmetrically up and down of the feeding roller 3 to prevent sagging, rolling and meandering of the screen 6.

The motor 10 located near the center of the case 1 is applied by adjusting to a low speed rotation by applying a reduction motor. When the belt 13 connected to both sides of the front feeding roller 3 is rotated by the rotation of the motor 10, the belt 13 of the motor 10 merely serves to rotate the advertisement screen screen 6. In addition, by the elasticity of the flexible belt 13, the front feeding roller 3 is always pulled outwards, which serves to act to allow the advertisement surface screen 6 to be unfolded and rotated. That is, for this purpose, the fixed position of the motor 10 is set to the center of the signboard, and the belt 13 in which the pulley 14 attached to the motor 10 is straight cannot be rotated, so the pulley 14 of the motor 10 cannot rotate. Rotating pulleys 15 and 15a are respectively installed on both sides, and the belt 13 passing through the rotating pulley 15 on one side is wound around the pulley 14 of the motor 10, and again the opposite rotating pulley ( When passing through 15a), the belt 13 is configured to U turn the motor pulley 14 so that the motor 10 can rotate the belt 13, and at this time, the rotating pulleys installed on both sides of the motor pulley 14 15) 15a are connected to each other with a spring so that they are always pulled inwards, so that the belt 13 wound around the feeding roller 3 is pulled toward the motor 10, so that the gripper 11 of the feeding roller 3 The rolled advertisement surface screen 6 is always rotated in a stretched state.

The motor drive control device basically consists of a detection element such as a photosensor for detecting the movement of the screen 6, and a control unit for controlling the power applied to the motor 10 and opening and closing the switch. The driving method is that the advertisement surface screen 6 is completely wound on one side of the feeding roller 3 and connected to the opposite winding roller 4, so that the power is turned on with the advertisement surface 1 being displayed. When the switch is turned on, the motor 10 is driven and the drum roller 5 is rotated through the belt 13 while the motor 10 is driven. The advertisement surface screen 6 is rotated while being wound on the drum roller 5. .

At this time, if a detection line marked at the lower end of the advertisement surface screen 6 is recognized by the detection element at a point where one cut of the rotating advertisement surface screen 6 is displayed on the signboard, the motor 10 is stopped. In the stopped state 10) again waiting for the first time specified in the previous step, the motor 10 is rotated by the number of cuts of the advertising surface in the order in which the drive is driven again and reversely rotated, and the motor 10 is driven If the controller is configured to remember the stopped state of the motor even when the power switch is turned off and then on again, the advertisement surface is reversed or the advertisement surface in the designated order rotates without change in the first specified sequence.

In addition, to keep the advertising screen screen rotated in the signboard to be kept clean at all times, and to prevent contamination without exposing the driving device and rollers, a cover is attached to the front window of the signboard and only the advertising surface is displayed. At this time, if the transparent film for the glass is attached to the back covering the front window, the internal electrical components can be safely protected against leakage caused by dust or rainwater from the outside.

In addition, in order to prepare the internal temperature to rise due to the heat irradiated from the internal lighting of the signboard to form an appropriate air inlet and discharge passage to lower the internal temperature of the case.
