Description

CRANE MOUNTED AUTO-PRINTER CAPABLE OF DEVISION PRINT}

The present invention relates to an automatic printing apparatus configured to print color images directly on the outer wall of a building using a crane.

In detail, when a printing surface to be output is relatively large, such as in an exterior wall of an apartment, such a printing image may be divided into arbitrary sections to be divided and output so that one large image may be expressed as if it were a live action. In addition, even if the print job is interrupted due to mechanical defects or external environment during printing, the crane-mounted automatic printing device capable of split output configured to output partly and selectively instead of reprinting the entire image. It is about.

To paint on the outer wall of a high-rise building, use a gondola or the like to hang the workbench on the rope so that it can be moved up and down, and paint the work directly while the worker is on the workbench, or by the worker on the rooftop. I've been painting down as I came down on the rope fixed to it.

However, this type of painting work requires the worker to work directly at a high position on the outer wall of the building, which is always exposed to the risk of falling accidents, and the risk of an accident increases even more on windy days. have. In addition, since the worker does the painting work at a high place, the movement of the worker is not free, as a result of this, the painting work is delayed, resulting in a problem that the working air is long. In addition to the risk of industrial accidents, the labor cost is unnecessarily increased due to the characteristics of the painting work performed by the worker by hand, which has been an increase factor of the painting work cost.

On the other hand, in order to draw a special image such as paintings, texts, symbols, and logos on the exterior walls of buildings such as apartments in order to provide aesthetics to the viewer, the designer may draw sketches on the walls of the apartments through the same means and methods as described above. After that, the painter draws the text that is marked with a brush or paint roller.

As the printing process of the exterior walls of buildings, especially high-rise buildings, is performed by hand, it is natural, but it is difficult to expect realistic value, especially in the production of pictures, patterns, and photographs by large prints. As it was not easy to represent a large image, the size of the output object had to be extremely limited.

Therefore, a large picture, a pattern, and photographs of the entire image are divided into several parts and produced in the form of a frame, and there has been a limit of expression in order to realize an image such as photorealism.

The present invention has been made in order to actively solve the above problems, it is possible to print a variety of images on the exterior walls of buildings such as apartments more accurately and quickly without errors using an automated device implemented by remote control, photos or Its purpose is to process pictures and other desired images, texts, phrases, logos, symbols, etc. in a short and sophisticated manner.

Another object of the present invention is to enable continuous color printing of a large-scale image close to live-action.

Another object of the present invention is to implement a structure that can be moved and installed more simply and easily.

In configuring the automatic printing device of the present invention to realize the above object,

A support frame having a diffraction link; And a main body frame accommodated in the support frame, wherein the main body frame has both vertical members; and a nozzle cradle interposed between the upper and lower vertical members so as to adjust the position of the transfer nozzle unit in the up, down, left and right directions. The main body frame, the nozzle cradle, and the position of the transfer nozzle portion is variable so that ink of various colors is sprayed by the transfer nozzle unit according to a previously input program.

The annular protrusion is formed downward on the bottom of the support frame, and the support member and the main body frame accommodated therein are rotated by being fixedly mounted on the outer member of the annular protrusion so as to be engaged with the gear axially coupled to the motor. Include what can be.

In addition, the rod of the driving cylinder integrally coupled to the fixing member of the crane boom is fixedly coupled to the inside of the diffraction link, and the support frame and the main body frame accommodated therein are forwarded by pushing or pulling the diffraction link by driving the rod. Or it can be tilted rearward.

And, at least one wheel is mounted to the horizontal axis of the support frame.

A rack gear is installed in each interior space of the nozzle cradle and the vertical member, and a reinforcement angle is fixedly mounted at both ends of the nozzle cradle so as to cover the outer edge of the vertical member, and a motor and a shaft coupled thereto are fixed to the reinforcement angle. The pinion gear is meshed with the rack gear of the vertical member to configure the nozzle holder to be driven up and down when the motor is driven.

In addition, the transfer nozzle unit is a jet port for ejecting ink; A laser sensor that emits light in an area where the image starts and ends to enable position adjustment through a monitor; And a fiber sensor for sensing whether the object surface is refracted or not.

In addition, the transfer nozzle unit is mounted with a motor coupled to the pinion gear and the pinion gear is configured so that the transfer nozzle unit can be reciprocated horizontally on the nozzle mount as the pinion gear is guided to the rack gear of the nozzle mount.

In addition, the transfer nozzle unit may include a position that can be moved back and forth by the engagement driving of the rack and pinion gear according to the measured value of the fiber sensor.

In particular, the position identification by the sensor is possible, so that there is no shortage of performing more precise and realistic color printing of large images.

In addition, in the case of an extra-large image having a relatively large printing surface as an output target, such a printing surface may be divided into arbitrary sections to be divided and output so that one large image may be expressed as if it is real. Even if the print job is interrupted due to a mechanical defect or an external environment during the print job, it is possible to minimize the consumption of ink by partially or selectively outputting the image rather than reprinting the entire image.

In particular, by operating the automatic printing device fixedly mounted to the crane, not only the operation method is monotonous, but also more efficient in movement and installation.

The main body frame 200, the cross support 210 which is disposed transversely at the upper end; and both vertical members 230 for supporting the cross support 210; and the transfer nozzle interposed between the upper vertical member 230 It may include a nozzle cradle 250 to enable the upper, lower, left, and right position adjustment of the portion 240, and a fixed support 260 extending from each corner point to be in close contact with the target surface.

The nozzle holder 250 is a component that enables the free positioning of the transfer nozzle unit in a state in which the transfer nozzle unit 240 is mounted, and the reinforcement angle 251 is integrally fixed to both ends. The reinforcement angle 251 is provided in a "c" shape is disposed to overlap the vertical member 230, the pinion gear 253 is fixed to the motor 252 by drilling a through hole on one side of the angle 251 To be received internally (see FIG. 8). As a result, the pinion gear 253 described above is engaged with the rack gear 231 provided in the inner space of the vertical member 230 to implement the vertical movement of the nozzle cradle 250. In addition, by mounting another rack gear 254 on one side of the nozzle cradle 250 can be made to drive the left and right of the transfer nozzle unit 240, which will be described later.

The transfer nozzle unit 240 is a component in which ink of various colors are ejected according to a pre-programmed, similar to the conventional technology. However, in the present invention, the pinion gear 256 and the motor coupled to the shaft 255 is mounted to guide the pinion gear 256 to the rack gear 254 of the nozzle cradle 250, the nozzle cradle 250 The transfer nozzle unit 240 is characterized in that the horizontal reciprocating movement. A bottom plate 242 having one side opened to form the outer edge of the nozzle cradle 250 is formed, and the pinion gear 256 enters the bottom surface of the bottom plate 242 so that the rack gear of the nozzle cradle 250 may be formed. 254), but not shown in the drawing, the bottom surface of the nozzle cradle 250 is formed so that the pinion gear 256 can be moved horizontally therein.

In addition, in the present invention, the transfer nozzle unit 240 may have a separate rack gear 244 so that the transfer nozzle unit 240 may be driven not only in the left and right directions (see FIG. 9) but also in the front and rear directions (see FIG. 10). ) And pinion gear 243 may be further installed. The rack gear 244 is disposed on an upper surface of the bottom plate 242 of the transfer nozzle part 240, and a top plate 241 on which a plurality of inks are mounted is fitted to the bottom plate 242, and one of the top plates 241 is coupled. By drilling the side to fix the pinion gear 243 associated with the motor 245, the upper plate 241 is driven back and forth in accordance with their engagement drive.

The transfer nozzle unit 240 is an injection hole 246 through which ink is injected; A laser sensor 247 that emits light in an area where the image starts and ends to enable position adjustment through a monitor (not shown); And a fiber sensor 248 for detecting whether the object surface is refracted.

The laser sensor 247 is a component for grasping the start point and the end point of a virtually partitioned space in outputting a large image. That is, the automatic printing device of the present invention is moved to each divided point by dividing the outer wall of the apartment, and the printing operation is performed. In order to connect the divided images, the beginning and the end of the image are connected to the laser sensor 247. After confirming with), by performing a print job, a continuous image can be implemented and can be expressed like a live action. In detail, the monitor determines whether the light emitted by the laser sensor 247 exactly matches the start point or the end point of the image, and for this purpose, a predetermined camera is further mounted on the transfer nozzle part 240. It is desirable to be. As the image taken by the camera is transmitted to the monitor, it is easy to check whether the laser light and the image match, and if there is a mismatch, the moving nozzle unit 240 and the main frame 200 are moved to confirm that they are exactly matched. Next, ink is injected through the injection hole 246.

The fiber sensor 248 detects the curvature of the printing surface and enables the distance between the printing surface and the injection hole 246 to be adjusted. When the printed surface (outer wall of the apartment, etc.) is partially protruded or recessed, when the fiber sensor 248 detects this and applies a signal, the upper plate 241 of the transfer nozzle part 240 is slightly moved forward and backward. The position of the transfer nozzle part 240 is adjusted to be an ideal injection distance.

In addition, the main body frame 200 of the present invention may further include a fixing stand 260 extending from each corner point to be in close contact with the printing surface. The holder 260 is further equipped with a horizontal holding sensor for detecting a horizontal state of the printing surface; and the length of the holder 260 can be changed according to the measured value. The pinion gear 263 connected to the motor 262 is accommodated in the horizontal member 220 so that the length adjustment can be made in the inner space of the horizontal member 220 below the cross support 210. It is the structure which engages with the attached rack gear 261 (refer FIG. 11). As a result, the fixing stand 260 can be adjusted in length while being drawn out or drawn out from the inside of the horizontal member 220.

On the other hand, look at the operation of the present invention made of the above configuration as follows.

As shown in FIG. 1, when a large image is to be printed on an exterior wall of an apartment, first, the entire surface is divided into virtual partitioned spaces, and then the main body frame 200 is positioned in each of the partitioned spaces. Will print.

The up, down, left and right positioning of the main body frame 200 can be performed by manipulating the boom 30 of the crane 10, and move the boom 30 up, down, left, and right to accurately position the main body frame 200 in a desired partition space. By applying power to the transfer nozzle unit 240 can be printed. Here, when it is difficult to properly arrange the body frame 200 with respect to the printing surface only by the operation of the boom 30, the most ideal positioning can be made by the operation of the rotating member 120 or the driving cylinder (50,270). .

That is, the rotation member 120 is rotated by the gear 21 coupled with the motor 20 to rotate the main body frame 200 in a clockwise or counterclockwise direction while adjusting the distance from the printing surface, as well as the case. Accordingly, the main frame 200 is leaned forward by relaxing the rod 51 of the driving cylinder 50 to push the diffraction link 110, or conversely, the rod 51 of the driving cylinder 50 is contracted to diffract the diffraction link 110. By pulling the link 110 backward, the main body frame 200 can be tilted backwards. In addition, by operating the driving cylinders 270 provided on both sides of the fixing member 40, the inclination of the main body frame 200 in the left and right directions can be adjusted. By this driving method, it is possible to implement the arrangement state of the main body frame 200 to perform the most efficient and precise work even in the printing operation in different positions up, down, left and right.

In addition, in the present invention, a plurality of rack gears and pinion gears engaged therewith are provided so that vertical, horizontal, left and right driving of the transfer nozzle part 240 on the main body frame 200 is free. The conveying nozzle unit 240 is mounted on the nozzle holder 250 and moved in the horizontal direction, as well as in the vertical direction by the pinion gear 253 which is driven in engagement with the rack gear 231 of the vertical member 230. Can also be driven.

The automatic printing apparatus of the present invention implemented in this manner is further equipped with a laser sensor 247 to enable continuous output of the image, and closely grasp whether the laser light matches the start and end points of the image through a predetermined monitor. By doing so, the images drawn in the partitioned space are perfectly connected to each other to produce a large-scale image close to the real world.

In particular, the fiber sensor 248 is applied to the transfer nozzle unit 240 to accurately determine whether the printed surface is bent, and according to the determination, the transfer nozzle unit 240 is configured to be moved forward and rearwards so that the injection hole ( 246) and the distance between the print surface can be properly maintained to increase the completeness of the print job.

The automatic printing apparatus of the present invention, by fixing the support frame 100 and the main body frame 200 to be able to operate the main body frame 200 on the support frame 100, these fixing means is a binding such as bolts It would be desirable to use a member. In addition, by applying a computer and various controllers for the overall operation control of the device, it is possible to finely adjust the position of the main body frame 200, as well as the transfer nozzle unit 240 in accordance with a pre-programmed, remote In order to enable accurate control at, the signal distance extender can be connected by cable to transmit the signal.
