In the process of labeling no adhesive substances such as glues are being used instead of which the label remains in place on the package due to the active elastic forces achieved through the process of putting the label in place using sliding a label on to a package of somewhat smaller diameter.
The advantages of this procedure over the previously used traditional methods of labeling are as follows: This roll of polyethylene foil is placed on the foil suspender and is secured with a safety switch.
The polyethylene foil rolls over a system of cylinder shaped rollers and a wire lever that serves a purpose of controlling the motor that in hand unravels the foil. The motor is controlled by this wire lever through a pair of initiators that are positioned on the axis of the wire lever a.
Thus the motor in charge of the unraveling of the foil continuously creates an amount of foil that stands as a reserve and enables the foil to be drawn by pincers or claws in regular recurring intervals encountering minimal resistance. The foil travels further over the system of cylinder shaped rollers and winches, through the system of two rubber rollers that do the task of correcting the position of the foil. After that the foil reaches the confirmatory unit and travels further to the photocell.
The pincers capture the foil and drag it further. Because the extraction of the label takes place in the air without any support for the foil the motor that corrects the position of the foil drags the foil slightly backwards to the photocell that is directed towards the brim of the foil. A single label carried by the pincers then slides on the bottle. The pincers are of mechanic-pneumatic type and the opening and closing of the pincers is done through the system of cams and a single pneumatic cylinder.
The uptake of the label is done through the action of the pneumatic cylinder which spreads the inner pincer towards the outer pincer covered with rubber and that results in grabbing a single label. After that the inner pincer is being led over the cam and the outer pincer is tightened over the springs.
The moment in which the label is being released is determined by the cam of the outer pincer and by adjusting this cam it is possible to adjust the level on which the label is released. The pincers than return to the upper position and the next bottle is brought in to the operating zone through the action of the bottle pusher.
In the operating zone in which the sliding-on of the label takes place the bottle is held by the force of the vacuum created by the vacuum pump. In case that the bottle gets lifted due to the retrieval of the pincers in their previous position upwards than the photocell of the lifted bottle will signal to the controller to stop the machine.
The machine also has an entrance transporter that takes the bottles to the bottle pusher. Travelling of the pincers upwards and downwards is done through the cams of the central axis.
The process of starting and stopping the machine is enabled through the system of friction bond-breaks. These bond-breaks function in a way that when the bond is in action the breaks are not and vice versa. Description of the label installment process Pos.

The machine is delivered to you along with two tool sets intended for two different types of bottles of two different diameters. Also we will supply you with two different programmers that ensure adequate installment of two different label sizes.
The selection between these programs is done through the switch inside the main electric cabinet. The machine independently through this system brings the bottles one by one into the operating zone. That means that the main executive elements of the machine operate in a sequence of synchronized rhythmic motions.
The machine has a foreseen capacity of between and bottles per hour. The movement of the main components is ensured through the transmission of power over the mechanical system and further through the curve mechanism with the buffering effect of amortization pneumatic cylinders.
These pneumatic cylinders have a role of keeping the curven rolls of these mechanisms with the curves preventing uncontrollable oscillations or jumping that might occur at higher velocities.
The machine is controlled with a programmable controlling unit that receives signals from the machine about the conditions of the executive parts of the machine through the system if sensors. This system of sensors also controls the security systems that protect the machine operator.
The stand of the machine is made from steel profiles covered with construction type steel sheets. The zone in which the installment of the label takes place is protected with a door made of Plexiglas and every attempt to open this door will cause the machine to stop working instantly. The bearing panels and all of the moving parts are made of an aluminum based alloy for the purpose of reducing inertial forces present.
The machine is composed of the following functional compartments: The mechanism of the main drive 2. Supplying the bottles 4. The suspender of the foil roll 5. Winch or reel 8.
Air distribution system 9. Coverings and sheet panels Main electric cabinet 4. The main drive pos. On this axis there are the copying unit of the main motion pos. The transmission of the momentum between the axis and a belt transmitter is done through the pneumatic junction pos. The lever mechanism of this structure is manufactured if full form aluminum based alloy in order to reduce any inertial forces present.
To ensure the safe and tight placement of the curven rolls of the curve mechanisms upon both lever mechanisms main movements and the supplying of the bottles have amortization pneumatic cylinders.
This pneumatic cylinder switches on each time the machine is put in motion and switches off each time the machine is put to a halt. This enables the machine operator to manually lift the pincers every time the machine is turned off in case that a bottle gets stuck under the pincer mechanism.
When the pincer mechanism is in the upper position the inner pincer pos. Over the cylinder for the label uptake pos. On the outer pincers there are rubber coverings that increase the friction force between the pincers and the labels. The main drive mechanism enables the pincers to move downwards. In this way the unraveling process does not encounter any friction or resistance.
The label extractors extract a single label and slides it on the bottle, after the machine has drawn just enough foil, a portion that needs to be little longer than a single label.
At a certain moment during its traveling downwards through the mechanism of the inner pincer pos. In a designated place for label release the outer pincer opens through the lever for label release. The label remains on the bottle due to the existing elastic force, and the inner pincer is automatically withdrawn during the downwards movements of this mechanism. In the down position the inner pincer is being activated once more that is it opens once again.
While this part of the cycle takes place the pressure in the cylinder for label release is increased to prevent the inner pincer to close during the descend of the outer pincer from the label release cam.
The bearer of this mechanism pos. This feature reduces any inertial forces that might occur when the machine operates at high velocity. This structure gets its momentum from the motion transmitting lever pos. The motion transmitting lever through the receiving lever pos. Pushing the bottle forward is done while the pincers are in an upper position. The curl spindle has a role of fixating the bottle pusher in its starting position. The bottle pusher always makes the same motion but a certain part of the way, depending on the fine tuning; it travels without pushing the bottles forward.
The difference between the length of this pathway and the entire pathway of the bottle pusher is to be equal to the transverse measurement of a single bottle. That means that between the onsets of the bottle pushing process and its completion the bottle pusher travels a pathway equal to the transverse measurement of a single bottle. This is essential because the perforated foil is very sensitive to the traction forces along the foil.
The unraveling of the foil roll is powered by the unraveling drive pos. The counter ballast pos. The foil roll is imbedded on the suspender pos. The confirmatory unit lean over the confirmatory unit bearer pos. The foil extractors which are also there pos. These foil extractors actually stop the row of labels that comes from the foil roll and thus allows the preceding label to be separated. It is comprised from a series of cylinder shaped rollers, tin sheets and springs.
In the moment of the label uptake these tin sheets are withdrawn in order to prevent the straining of the label and a sub sequential tearing of the label. After the separation of label these tin sheets spread once more to keep the foil tight. The confirmatory unit hangs on a confirmatory bearing cylinder shaped roller pos.
