The operation of the entire machine is controlled by an automatic control system, an advertisement stepping machine can contain 30 spray paint posters of 108m#+[2], the advertisement stepping machine can stop and advance automatically and be operated left and right in a reciprocating way for 15 hours per day. The utility model is automatically opened and closed.

Description

The advertisement stepper

Technical field

The utility model is a kind of large automatic advertisement machinery (model machine 6m * 18m) can hold the 108m2 painting advertisement to draw 30 width of cloth, applicable to the public place that personnel such as station, square, harbour concentrate, be the cheap advertisement machinery that complements each other with electronic large screen.

Background technology

At present, the advertisement machinery of driving painting advertisement cloth all is that picture is at 10m on the market ²Following small-sized machine.And the electronic large screen cost is high, be difficult for to popularize and power consumption big.Light emitting diode damages easily, also is the reason that the inconvenience of most of advertising companies is used.

At above-mentioned reason and market demands, the utility model is by research and practice, has solved advertisement cloth the be in operation problem of dangling and the variable motion in the mechanical movement, and through model machine operation more than a year, has made the utility model become ripe advertisement machinery.

Summary of the invention

Advertisement step machine can be divided into four parts: mechanical part, automatic control system, support body and cover part, set up part.

One, mechanical part

Two groups of running gears (Fig. 1) that the advertisement stepper is made up of four 6.6m long main drive shaft, driven shaft.Main drive shaft is by corresponding motor-driven, and configuration wheel box and autobrake system.After painting advertisement cloth is wrapped on the main drive shaft, by about two groups of motors drive intermittent duty in turn.

The technological difficulties of this machine are to solve dangling and because of the problem of long term wear, aging formed wrinkle influence operation, having designed all kinds of corresponding assistors for this reason of the advertisement cloth that is in operation.

1. lifter (1) dangles: in the middle of picture top, freely swing with the picture operation, promote the picture (Fig. 2) that dangles.

2. assistor: on picture top, 1 every meter, its function only keeps picture parallel, does not possess lifting force.

3. main drive shaft removes the device that wrinkles: each 1 up and down on main drive shaft, can swing with picture, and also can move forward and backward with the thickness of advertisement cloth on the main drive shaft.Main effect is to remove the wrinkle that form because of the motion of advertisement cloth on the main drive shaft, makes advertisement cloth twine standard (Fig. 3).

4. driven shaft removes the device that wrinkles: each 1 up and down of driven shaft, and function is similar with the main drive shaft device that goes to wrinkle, and unique difference is following 1 effect (Fig. 2) with evener.

5. automatic straightening device: each 2 of picture top and the bottom.The edge of the artificial 540m picture of pasting is difficult to guarantee cause picture to fluctuate up and down easily on a horizontal line, and is very big repeatedly.The function of automatic straightening device is exactly to accept the instruction of sensor, is responsible for rectifying a deviation of picture, makes picture keep balance (Fig. 3).

6. evener: be installed in the lifter that dangles just below.Make it and the lifter that dangles forms equilibrium of forces (Fig. 2) up and down with fine setting.

The task of various assistors in the advertisement stepper is to make the advertisement picture open and flat no wrinkle that is in operation, and fluctuates up and down less than 6cm, makes advertisement cloth twine standard, neat on main drive shaft.

Two, automatic control system: the control system of advertisement stepper can be divided into four relatively independent parts and form.

1. operation part: the advertisement stepper be in operation because of about twine the variation of advertisement cloth thickness and weight on two main drive shafts, make travelling speed all the time in variation, therefore, control system with a Frequency Converter Control about the running frequency and the torque of two motors, make advertisement stepper picture move relative uniform motion.

2. left and right sides knuckle section: turning to behind intact 30 width of cloth of the every operation of advertisement stepper, be responsible for by a near sensor that is arranged on the driven shaft, being responsible for of the left side turn right to, the sensor on the right side is responsible for turning left.

3. middle pause part: the advertisement stepper whenever advances middle dead time of a width of cloth, is finished by two sensors and the time relay.

4. automatic straightening part: four independent high frequency sensor that are provided with of the work of automatic straightening device are responsible for, each high frequency sensor control automatic straightening device (Fig. 2).

Three, support body and cover part

The support body of advertisement stepper is made of steelframe, and its structure has two characteristics:

1. the support body front is arc (Fig. 1), is to solve the part that picture dangles.

2. the integral body of doing the tinned sheet iron of arc frame dignity plate must be smoothly not have protrusion, to the picture not damaged, is convenient to slide about advertisement cloth.

The cover part of advertisement stepper is made of steelframe, and anti-dust, windproof, rainproof, snow defence are made of in the front transparent organic glass.

Four, set up part

Set up part for to beat the light part outward, control by the micro computer time switch.

Description of drawings

Fig. 1 is the synoptic diagram of arc support body of the present utility model and the trajectory diagram of advertisement cloth operation;

Among the figure, 1 main drive shaft, 2 driven shafts, 3 arc support bodys.

Fig. 2 is lifter, the driven shaft location drawing of device, evener, high frequency sensor that goes to wrinkle that dangles;

Among the figure, 1 dangle lifter, 2 driven shafts go to wrinkle device, 2 ' time driven shaft go to wrinkle device, 3 high frequency sensor, 4 eveners.

Fig. 3 is main drive shaft go the to wrinkle location drawing of device and automatic straightening device.

Among the figure, 1 main drive shaft go to wrinkle device, 2 automatic straightening devices.

Embodiment

Among Fig. 1, direct motor drive main drive shaft traction advertisement cloth, when a side move, advertisement cloth was along arc support and driven shaft slip, move 30 width of cloth after, move to the opposing party again, run so forth.

Among Fig. 2, the position of the lifter that dangles promotes picture when being responsible for the picture operation in the middle of the top of whole image, make the picture keeping parallelism, four driven shafts go to wrinkle device be in operation promote and under pull picture, make not occur wrinkle on the driven shaft.Evener can be finely tuned, and makes its strength of pulling down keep balance with the lifting force of the lifter that dangles.

Among Fig. 3, the main drive shaft device that goes to wrinkle is after advertisement cloth moves one or two months, draws limit wearing and tearing, aging, upwards puts the effect of pulling, and it is smooth that main drive shaft advertisement cloth is twined.Four automatic straightening devices play correction in that picture is in service under the control of high frequency sensor.
