Background
According to the relevant standard regulation, when the steel pipe is produced, a single or a plurality of color rings with certain width are sprayed at the corresponding position of the steel pipe body, and the steel pipes with different steel grades have corresponding color ring combinations (such as two bright green color rings of a K55 steel-grade oil sleeve). At present, the steel pipe color ring spraying equipment adopts two modes of spraying a color ring by a spray gun or printing the color ring by a roller. The efficiency is low and the shape is easy to distort when the color ring is sprayed. The disadvantages of spraying the color ring by using a spray gun are as follows: the width of the color ring is not easy to control, the angle and the position of the nozzle are often adjusted to meet the process requirements, the production efficiency of the whole production line is reduced, and more serious, the sprayed gasified paint is easy to diffuse all around, generates environmental pollution and especially brings damage to nearby process equipment. When carrying out steel pipe body colour ring spraying operation, the steel pipe body need be circumferential direction rotary motion under the drive of rotatory bearing roller, and the axial float of certain degree can take place for the steel pipe body usually when doing circumferential direction rotary motion, if nozzle or gyro wheel can not follow the steel pipe body and remove, then the colour ring or the coincide that the head and the tail can not be intact of production, perhaps the shape distortion, steel pipe appearance quality receives very big influence this moment.

Although the printing automation of the girdle band is realized, only one steel pipe can be rolled and coated each time, and a plurality of steel pipes are queued subsequently, so that the efficiency is low. The phenomenon that the turnover pipe can not fall into the ink box groove often occurs, special manual supervision is needed, faults are eliminated in time, and printing is recovered.
The novel patent (CN205904051U, 20170125) of Shanghai Baoshan iron and Steel works Limited discloses a floating steel pipe color ring printing device, places the steel pipe in rotatory compression roller pair 123, 123 'and the rotatory bearing roller 118, 118' that sets up in the ink horn, rotatory compression roller drives the steel pipe and rotates, and the steel pipe is rotatory to drive rotatory bearing roller and rotates, and rotatory bearing roller rotates and scribbles the steel pipe excircle with color ring paint.

The working principle is as follows:
in order to solve the problem of 'automatically rolling and coating a plurality of pieces', the utility model discloses a following technical means:
1) vertically and transversely arranging pipes at intervals, wherein the intervals ensure that one-time multi-pipe walking and fixing are all in correct positions
For 6 tubes, coating requires a fixed spacing L0Rotating in the roller coating groove, 6 steel pipes at a time with a fixed interval L0The transverse pipes can be ensured to move forwards or roll-coated at a fixed interval after entering the pipe. In the direction, only vertical pipes and horizontal pipes are arranged, the production line which is connected one by one and cuts off the steel pipes forwards along the roller way is easy to connect, and the production line only needs to connect the upper stream of the vertical pipes through a parallel header device and vertically arrange the pipes after 6 steel pipes are arranged side by side. The header device is easy to arrange 6 tubes side by side, and as long as the header device moves forwards at a constant speed along the transverse direction, each tube arrives from the roller way at a fixed time interval, and the counting is only needed when the tube moves forwards.
Meanwhile, a vertical distance is arranged in the pipe, when the pipe is arranged, the distance input is also carried out on the transverse pipe arranging mechanism, and the distance row teeth of the transverse pipe arranging mechanism move forwards by 6L0Braking is carried out, and after braking, the 6 steel pipes are still in a fixed distance L at a new position0Are arranged at intervals and are positioned by the distance row teeth.
In addition, it should be noted that this parallel header apparatus is not necessary for the vertical pipe of this apparatus, because as long as you are going into the pipe 6 at a time with a fixed interval, even if 6 steel pipes are manually arranged side by side, the vertical pipe-entering mechanism of the present invention can work as well.
2) The arc groove, the rolling coating groove and the row teeth are mutually matched, the walking is a group of distances, and the fixed is L0To realize dynamic distance setting
The arc groove of the feeding roller, the row teeth of the row pipe chain and the rolling coating groove of the ink box have equal and fixed intervals L0Each forward moving distance of the calandria chain is a group with a fixed distance L0The width of the aligned steel tubes, i.e. n L0. When the row teeth move forwards, the distance of one group of steel pipes is certainly moved forwards, the foremost group of steel pipes of the storage pipe track is just positioned right above the rolling coating grooves, and when the first lifting track 11 descends, the n steel pipes are just positioned in the n rolling coating grooves; when the calandria chain stops, the steel pipes arranged on the storage pipe rail 12 are at a fixed interval L0Spacing, therefore, by the mutual cooperation of the arc grooves, the roll coating grooves and the row teeth, the distance is determined by ' walking ' and the distance is determined by ' L0And realizing dynamic distance setting.
3) Period design of binary intermittent action of roll coating automation
① jacking the first and third tracks, moving the rear row of teeth by a set distance for a time period t, lowering the ② first and third tracks, erecting the feeding mechanism 20 into n new steel pipes for the same time period t, finishing the roll coating of the n steel pipes by the roll coating groove, circularly returning to the step ①, and realizing the roll coating automation of finishing the roll coating of a set of n steel pipes in 2t time length by the binary intermittent rhythm arrangement.
The division is carried out according to the forward moving and the non-forward moving of a plurality of groups of steel pipes on the track, the new pipe feeding action of the feeding roller belongs to the fixed state relative to the steel pipes on the track, the roll coating groove roll coating belongs to the fixed state relative to the steel pipes on the track, and the new pipe feeding outlet pipe and the roll coated steel pipe outlet pipe belong to the moving state relative to the track, so the division is carried out in a binary way.
According to the time length required by 'moving' and 'fixing', the jacking/descending actions of the first track and the third track before moving are added in a matching way, and the automatic cycle period is designed as (t is the time length, the unit is second):
step 1) tStarting point+ t (first time section), first, third track jack-up,the back row of teeth are spaced by a group;
step 2) tStarting point+2t (second time period), descending the first track and the third track, feeding by a feeding roller, and simultaneously rolling and coating by a rolling coating groove;
Tstarting point＝tStarting point+2t, perform step 1).
