The machine function of tonic chord is set to " sending the mark device " on man-machine interface, and mark speed is sent in setting, the decals position, stop cursor position, tag length parameters such as (tag length of this moment are by the length setting of individual label), label is marked the device label around installing (label detection and location sensor can detect the gap between the label) on the machine to figure (permanent tension force or permanent moment of torsion) according to sending, then when machine run, in case the survey thing sensor (not drawing among the figure) of machine detects by the object of decals or receives other outward sign when needing decals, being converted into a time delays according to the decals position of setting starts main motor and (becomes impulse rate output pulsed drive master's motor (stepping motor or servomotor) by control system according to the mark rate conversion of setting of sending, or by external pulse direct drive master motor), main motor drives the label operation by messenger chain transmission driven roller, on the peel plate place pastes label peeling by the decals object (or other connects in the mark mechanism), the label tail band is then collected by wind-up roll.When the slit between label detection and location sensor to two label, stop cursor position (being converted into the pulse count that continues output by control system) stop pulse output (or disconnecting external pulse) to stop main motor and driven roller according to what set (when the slitter edge between the label on the label roll is not removed, or lose label on the label roll, when label sensor can not detect label gap, then be converted to the output pulse count by control system according to the tag length of setting, after finishing pulse count, stop main motor and driven roller), finish and once send the mark action.

2) the device function setting of unrolling:

The machine function of tonic chord is set to " device unrolls " on man-machine interface, and mark speed, tag length (tag length of this moment is by the total length setting of every volume label that unrolls), label quantitatively (being the number of labels on every volume) are sent in setting, with label according to unroll the device label around to figure (permanent tension force or permanent moment of torsion) install (label detection and location sensor can detect the gap between the label), when then starting the machine, main motor promptly drives driven roller driving label according to the mark speed of sending that is provided with, and rolling-up mechanism then reclaims label.Machine accurately stops when tag length is finished.The sensor in tags detected gap does not stop driven roller at every turn under the device function of unrolling when detecting label gap, only give other external equipment (as the chopping machine of on label, printing the label position signal output, or the check implement of tags detected quality), write down the number of labels of process simultaneously.If stop when also needing to set the quantity that arrives every volume label, then set the number of labels (label is quantitative) that needs, and parameter is provided with " number of labels " in the interface sets other " stopping/not stopping " button settings and be " stopping ", can accurately stop when setting number of labels arriving.If every volume label quantity is main setting requirement, and every volume label length is for reference only the time, then need tag length to be set to be not less than total length under the specified number of labels, in order to avoid when number of labels did not reach as yet, machine stopped after having finished rewinding label length.Whenever finish and once unroll when stopping, meter output is finished one.

3) permanent tension rolling function setting:

This function need be matched winding motor and rolling energy disperser and buffer position sensor.All can use this function sending under mark device or the device function of unrolling.

Enable label winding motor 2 on man-machine interface, the wind-up roll transmission is with on the synchronous driven pulley 16 of wind-up roll that is connected on the winding motor 2 synchronously, and 4 pieces of joint bolts of wind-up roll 9 torque plates 24 outer rims are loaded onto, wind-up roll 9 is promptly driven by winding motor 2.Label during according to permanent tension rolling is around to figure (sending the mark device or the device that unrolls) label being installed.The start and stop of winding motor 2 are to be triggered by the buffer position sensor of rolling energy disperser under state of runtime machine, therefore in wrapup procedure, the tension variation of rolling only is the tension variation of rolling energy disperser when diverse location, its variation range is very little, therefore this rolling mode is permanent tension force, is not subjected to the influence of label roll vary in diameter.The structure of the rolling-up mechanism and the energy disperser that unrolls and principle of work are seen below and are stated.

4) permanent tension rolling send the mark function;

Simultaneously, compare with the existing mark device that send on the market, the utility model also has following characteristics:

In axle, the wheel of the messenger chain of driven roller 6, wind-up roll 9 these stepping rotating mechanisms connect, adopt elasticity wedge key 21 to connect, eliminated the gap that axle, wheel connect fully, can compensate the gap that reasons such as manufacturing errors cause, and install and remove very convenient, solved like product axle, the elimination of wheel key connection clearance, compensation difficulty or torn the problem of changeing difficulty open, the equal conditions subscript is signed bit error and has been reduced 30%～50% than like product.

Adopt the resilient wedge key connecting on the driven roller messenger chain: adopt elasticity wedge key 21 to connect between synchronous pulley (by main motor through strap drive synchronously) and the drive roller shaft 61 to drive drive roller shaft 62, employing elasticity wedge key 21 connects drive driven roller 6 between drive roller shaft 61 and the driving roll wheel 62.Because driven roller 6 is that the high-frequency stepping is rotated in sending the mark process, the gap of therefore eliminating between its messenger chain send mark precision and parts life-span extremely important for raising.

Adopt the resilient wedge key connecting on wind-up roll 9 messenger chains: when adopting permanent tension rolling function (4 pieces of screws of torque plate outer rim are loaded onto among the figure), the wind-up roll synchronous pulley is by the synchronous strap drive of winding motor 2 warps, through 4 pieces of screws (being aided with the friction force between the dish of clutch-plate and belt wheel limit) on the torque plate 24 moment of torsion is sent on the torque plate 24, adopt elasticity wedge key 21 to connect drive rolling roll shaft 91 between torque plate 24 and the rolling roll shaft 91, form between synchronous driven pulley 16 of wind-up roll and the rolling roll shaft 91 and be fixedly connected, adopt elasticity wedge key 21 to connect between rolling roll shaft 91 and the wind-up roll flange 25 and drive wind-up roll flange 25 and wind-up roll 9 rotations.Because wind-up roll also is that frequent starting stops when rolling, it is extremely important for keeping rolling to stabilize and increase parts life-span therefore to eliminate its drive gap.

When inactive permanent tension rolling, when using permanent moment of torsion rolling instead, remove 4 pieces of screws of torque plate outer rim, the synchronous driven pulley 16 of wind-up roll changes by main motor 1 through synchronous strap drive (seeing the transmission diagram under the permanent moment of torsion rolling pattern), be not fixedly connected between synchronous driven pulley 16 of wind-up roll and the rolling roll shaft 91 this moment, compress stage clip 32 by housing screw 31, stage clip 32 is pressed on clutch-plate 35 on the dish 36 of belt wheel limit (pressure is born by torque plate and fluted nut in the opposite) by pin 33 and platen 34, by clutch-plate 35 and belt wheel limit dish 36, friction force between the torque plate 24 is delivered to the moment of torsion on the synchronous driven pulley 16 of wind-up roll on the torque plate 24, be delivered to rolling roll shaft 91 by elasticity wedge key 21 again, rolling roll shaft 91 is delivered on the wind-up roll 9 by elasticity wedge key 21 again.When machine run, because wind-up roll 9 linear resonance surface velocities calculate all the time greater than driven roller linear resonance surface velocity (stating calculation specifications as follows) according to being fixedly connected, therefore label (label tail band or film) is slack-free all the time in the wrapup procedure, in case during the moment of torsion that the moment of torsion that its tension force produces produces greater than clutch-plate 35, clutch-plate 35 promptly skids, and makes wind-up roll 9 surperficial actual linear velocity consistent with driven roller 6 linear resonance surface velocities.It is the friction force of scalable clutch-plate 35 that housing screw 31 is regulated stage clip 32.Along with the increase of take-up diameter, the tension force of rolling will reduce gradually.When being used to send mark device function, driven roller 6 and wind-up roll 9 all start continually and stop, and driven roller 6 is when stopping, the rolling part overcomes clutch-plate 35 under effect of inertia friction force is rotated further, make label continue tensioning, unilateral bearing 37 prevents that then rolling roll shaft 91 and wind-up roll 9 from stopping the counter-rotating that the back produces owing to label tension force, therefore compensated reducing of rolling tension force to a certain extent.Take-up diameter is big more, and rolling speed is high more, and the start and stop frequency is high more, and this tension compensating effect of being brought by inertia is obvious more.So under permanent moment of torsion rolling pattern, reducing of rolling tension force is not to increase with take-up diameter to be 1: 1 reciprocal relation, but is the trend that slowly reduces.
