Description
Technical field
The invention belongs to and relate to the packing technique field, particularly a kind of automatic labeling machine with constant tension mechanism.
Background technology
Automatic labeling machine is a kind of manufacturing line that is used for, and product (commodity) is sticked automatically the equipment of sign (trade mark).
One, the structure of automatic labeling machine and principle of work:
Automatic labeling machine mostly is made up of following components (parts) both at home and abroad at present: referring to Fig. 1.
1-marks storehouse (unreeling structure):
The mark storehouse of automatic labeling machine is the device that is used to store marker tape and unwinding tension is provided for tape roll.Labelling machine uses the dish type marker tape, and marker tape is as shown in Figure 2.The matrix of marker tape is the antiseized paper tape of strip shape, attaches the non-drying glue of wearing sign (trade mark) on it.Use for ease of automatic labeling machine, marker tape all coils rolling (dish), pan of a steelyard shape marker tape again.Get loose voluntarily from the marker tape dish for preventing that marker tape is in operation, generally be provided with the mechanism that utilizes spring force or friction, marker tape is tightened up, to produce so-called unwinding tension.
2-dancing bar:
The dancing bar is the response agency of labelling machine unwinding tension.Labelling machine is in operation, owing under the effect of the tractive force that paper-feeding mechanism (marker tape trailer coupling) is produced, marker tape is involved in the marker tape dish; Because the marker tape dish has certain inertia, thus in a single day spur marker tape, owing to the reason of inertia; Have long marker tape and in the marker tape dish, get loose, at this moment, unwinding tension disappears; But under the effect of the spring force of dancing bar, can make marker tape tensioning again again, the marker tape unwinding tension recovers.
3-marker tape braking force mechanism:
This system of mechanism has a guide pulley and an elastic pressuring plate to constitute, and marker tape passes through between cylinder and the compressing tablet, and the pressure of compressing tablet is regulated by spring.Pressure is different, and marker tape is suffered that friction force is also just different, and this friction force also is the part of marker tape tension force.
4-decals head and stripping plate:
The decals head of labelling machine is the parts of labelling machine near affixed object, the decals head the stripping plate is housed foremost, its function is with sign (trade mark), under the effect of marker tape tension force, peels off out and transfers on the affixed object (commodity) from marker tape.
5-identifies photocell eye:
The sign photocell eye is the motion that is used to detect marker tape, and after marker tape has moved a step pitch (L) (referring to Fig. 2), it just sends instruction stops the marker tape conveying mechanism immediately, to guarantee only to paste a sign (trade mark) on each affixed object.
6-marker tape conveying mechanism (or claiming the marker tape trailer coupling):
The motion of marker tape in labelling machine is to be realized by the tractive force that paper-feeding mechanism (marker tape trailer coupling) is produced.One piece of sign of every subsides (trade mark), paper-feeding mechanism just make marker tape move a step pitch (L) (referring to Fig. 2).
The 7-rolling-up mechanism:
Sign on the marker tape (trade mark) is attached to after affixed object (commodity) goes up, and marker tape just becomes the blank base stock that does not have sign (trade mark), and rolling-up mechanism is just collected coiling with it and got up.
8-is support fixedly;
Be used for fixing various parts.
9-marker tape transition roller;
Marker tape in the process of walking, to the change of marker tape direction of travel.
The 11-marker tape.
Affixed object (goods or commodity) detector:
It is the external device (ED) of labelling machine, is used to detect affixed object.In manufacturing line, when affixed object arrives the desired location, just instruct automatic labeling machine that it is sticked sign (trade mark).The affixed object detector can be an electromechanical detector, also photoelectric detector.
Two, the job analysis of automatic labeling machine:
1, the working process of automatic labeling machine:
In the manufacturing line of operation; When the affixed object detector finds that affixed object (commodity) arrives preposition; It just orders the marker tape conveying mechanism to start immediately; Traction marker tape motion, marker tape be during through the front end of the stripping plate on the decals head, and the sign on the marker tape (trade mark) is just peeled off out and changeed and be attached on the affixed object from marker tape.When marker tape had been walked a step pitch (L) (referring to Fig. 2), the sign photocell eye stopped with regard to immediate command marker tape conveying mechanism.This has just accomplished the automatic poster process of a sign (trade mark).When the affixed object on the manufacturing line was sent here continually, automatic labeling machine just constantly sticked sign (trade mark) to each affixed object; Sign (trade mark) also just constantly transports out from the mark storehouse of labelling machine with marker tape, the concise and to the point working process of Here it is automatic labeling machine.
2, the dynamics analysis of automatic labeling machine working process:
Can know that from above-mentioned introduction the work of automatic labeling machine has following characteristic:
A, automatic labeling machine be always with gap mode work, the process that one piece of sign of every subsides (trade mark) all have startup, stop.
B, because its mode of operation is frequent startup, stopped process, therefore, the tension force in the marker tape just always is among the rapid variation.
Analyze the Changing Pattern of the tension force in the marker tape.When labelling machine begins poster process, at first be to start the marker tape conveying mechanism, the pulling marker tape; Marker tape dish in the mark storehouse receives the effect of pulling force and will rotate, because the inertia of marker tape dish is bigger, its marker tape length of seeing off can be much larger than a step pitch (L) (see figure 2); Can make the marker tape of CDEF section be in relaxed state fully, promptly the tension force of this segment mark band just changes to zero tension force (lax fully) once by the required tension force (unwinding tension) of pulling marker tape dish, because marker tape has relaxed; The dancing bar can be swung to counterclockwise under the effect of torque spring power; With the marker tape tension, therefore, the tension force in this segment mark band is to be in the steep variation again; Change to zero from unwinding tension, progressively return to the unwinding tension of former setting again suddenly.Also having, produce the device of mark storehouse unwinding tension, all is to adopt a torque spring, and its moment of torsion is set by manual work, is a definite value in the whole service process.But, in the labelling machine operational process, get on because sign (trade mark) constantly is attached to affixed object; The diameter of tape roll is constantly to reduce; Along with reducing of diameter, unwinding tension just constantly increases (because of the torsional moment of spring is a definite value), therefore; Itself also changes unwinding tension, is not constant.Owing to after marker tape is lax, the dancing bar progressively recovers unwinding tension under the effect of torque spring again, but in this process, dancing pole pair marker tape also has the effect of impulsive force, just makes the tension variation situation more complicated.More trouble is, mentioned strain changes, the process of adjustment can not be synchronous with the beat of labelling machine decals, and particularly in the process of high speed decals, the decals speed of general automatic labeling machine can both reach the level of per minute hundreds of piece, and promptly the decals cycle is very short.But because the inertia of mark storehouse, tape roll and dancing bar is bigger, the cycle of its tension adjustment, therefore, in the cycle, the Changing Pattern of tension force was all different in the marker tape at each decals much larger than the decals cycle.Marker tape tension change law non-constant, just cause having pasted a mark after, the sign (trade mark) that next preparation is pasted makes the decals position unstable at the stopping of the stripping front edge of board of decals head, holding fix different (referring to does not have repeatability).Also promptly be difficult to sign (trade mark) accurately is affixed on the affixed object appointed positions.The major cause of the current various labelling machine decals positional precisions of influence that Here it is.
Further analyze marker tape tension force to the decals position effects.Investigate the tension force in the ABC segment mark band again, the tension force in the ABC section is made up of two parts, the tension force of first CDEF section, and it two is friction force that pressure produced of damping leaf.Know from top analysis; The tension change law of CDEF section all is different in the cycle at each decals; And the friction force that damping leaf produces; Because spring leaf pressure is constant when labelling machine is worked, the friction force of its generation also is constant, so just constant at the Changing Pattern of each decals in the cycle by the tension force of its generation.Therefore, tension force is caused by CDEF segment mark band tension change law difference in the difference of the Changing Pattern of each decals in the cycle in the ABC segment mark band.After tension change law difference in the ABC section will cause a sign (trade mark) to paste, the sign (trade mark) that next preparation is pasted produced deviation (error) in the position that the front end of decals head stripping plate stops, waiting for, and this will cause decals position generation error.Must analyze and can know from above, the tension change law in the ABC segment mark band is in the difference of each decals in the cycle, be owing to the tension change law in the CDEF segment mark band each decals all different causing in the cycle.Therefore, in order to improve the decals positional precision of labelling machine, will make the marker tape tension force in the CDEF section all identical at the Changing Pattern of each decals in the cycle, these are in existing all automatic labeling machines both at home and abroad, because physical construction all can't be accomplished.
