sleeve shrink BOTTLE LABELLER

Only professional persons can operate the electric units. Particularly, before any handling in the control cabinet, all power supple to the machine shall be disconnected. The main power supply may be switched off by disconnecting the main circuit breaker.

• Electric shock risk: Even though the main power of the machine is turned off, or the main circuit breaker is disconnected, there are some electric elements in the circuit charged with electricity.
• Burning risk: The current may lead the electric elements to be temporary or long period hot, be careful when touching power line cable, control cable, power supply cable, junction box cover and motor casing.
• Even the machine is turned off, as long as the breaker of the power supply circuit is closed, the power line cable is still charged with electricity. For details refer to the electric principle diagram.
• Dust collector shall be used for cleaning the control cabinet. Direct cleaning with unfiltered compressed air is not allowed because water and oil content in the compressed water may lead to short circuit and reduction of insulation resistance.

• Before turning on, check the bolts of each mechanism to see if there is any loose situation.
• Upon turning on, try to run each mechanism with Manual key to see if there is any abnormal situation, Automatic running can be carried out only under no abnormal situation.
• When the emergency stop switch is turned on the cutting mechanism will search the original point automatically. Before turning on, make sure that the central column has been tightened in the right position, otherwise the central column and the cutter may be damaged.
• After replacing the cutter blade, check and see if the blade is too long. Too long blade may damage the cutter.
• During standby or normal running situation, do not put hands into the working area of the cutter.

Manual label feeding will not work in case the clean-down unit is not turned on.

The main machine, conveyor and shrinking oven etc. shall be adjusted to be in one straight line. The centre of the conveyor and the cutter head centre of the main machine shall be aligned with each other and the reference plane shall be adjusted to be level. The foundation bolts of the main machine shall enter the support ground without any clearance. Check and confirm the voltage of the power supply. Enough space shall be left for positioning of the main machine for the convenience of future spot check and repair. The ambient temperature shall be not higher than 45°C to avoid defects of bought out components. The placed location of the main machine shall be free from direct blow of fan or cold air, and flowing air may impact label sleeving.  

• Turn on procedure                                                                                      ● Turn off procedure

• As showed in above figure, put the label film material on the material rack, insert film material pressing plate and slightly apply pressure before tighten the rack screw.
• The material comes out along the direction as showed in the figure, and the material feeding roller opens clockwise so that the film material will pass through the rollers.
• Pull the label film material through various rollers as per the figure and then pull it into the tailplane of the central column.
• Open the driving wheel before pulling the film material into the central column, and then hold the bottom of the central column with left hand and lift it up so that the roller of the central column disengaged slightly from the main driving wheel. Pull the film material through the cutting position with right hand and then pull back the central column with right hand and secure it.
• After the central column returns to the original position, pull back the upper driving wheel and secure it with slight contact. Then the label installation has completed.

• Since the color, shade and thickness are different for different labels, sensitivity of the electric eye may influence label sleevingwhen replacing different label film material even though we have adjusted and set up the machine before dispatch and during installation. Too high or too low sensitivity will result in abnormal insertion of clean-down label during operation. Normally too high sensitivity may lead to shorter label length, while too low sensitivity may lead to the situation that a series of label film material has been pulled down. In case of the above situations, sensitivity of the electric eye has to be adjusted so as to meet the condition of the related label film material.
• Before adjustment of sensitivity, pull the label to be near the electric eye and confirm that the printing transparent point is at this position. Check if the red lamp and green lamp on the electric eye sensor are off. If moving the label up and down cannot make the red lamp off, it means the transparent sensitivity is weak. Align the transparent section of the label with the electric eye and adjust the sensitivity button on electric eye until the red and green lamps are just off, and then adjust backward until the red lamp is on.
• In principle both red and green lamp shall be adjusted to lighting. Sometimes too strong transparency of printings etc. on the label film material may lead to misjudgment of detected position of electric eye, resulting in abnormal insertion of label.

In case it remains abnormal after adjustment, repeat the above steps and adjust the sensitivity knob on the sensor a little bit more or less in order to detect the proper position of the sensitivity knob.

Adjust as per the following figure, in case the label inserts to the bottle as showed in figure A, move the electric eye toward B direction. In case of figure C, move the electric eye from C towards B direction, until the label inserts to the bottle like showed in figure B.

• This electric eye is reflection type with removable structure as the main body installed on the guide way. The main body reflects the projected light on the object with label sleevedand then it is reflected to the main body for receipt as the signal transmission of label sleeve.
• When there is no object for inserting, the lamp on the main body sensor shall be OFF. If under this situation the lamp is still ON, use small screwdriver to adjust this sensitivity knob until the lamp is OFF.
• When there are objects for inserting, the projected light is reflected by the bottle and the lamp on the sensor shall be ON. If the lamp is still OFF, it means that the projected light of the main body is too weak to reflect, and the sensitivity knob shall be adjusted until the lamp is ON.
• Repeat the above adjustment until proper sensitivity of the sensor is confirmed.

• Inconsistent linear speeds of three units: conveyor line, screw of bottle separation and bottle carrying positioning belt, may result in impossible insertion or unstable insertion of label.
• The following shows forward inclination of bottle: reasons: 1. too fast running of bottle carrying belt; 2. too slow running of conveyor line.
• In case the bottle inclines backwards, the situation will be the other way round.

The following phenomenon can be adjusted to be consistent through the knob on the panel.

• The label cannot be sleevedto the right position
• Reasons:

1. The hairbrush does not touch the label;
2. The bottle carrying belt is too high;
3. The lower part of the label is not in proper position;

• The lower part of the label is in proper position (due to the following two reasons)

     Figure 2: Move the bottle monitoring sensor towards the direction of bottle coming

• In case of replacing the blade, dismantle the unit as showed in the above figure.
• When replacing the blade, pay attention to number of remaining lattice of the original blade, i.e. the length of the blade. The new blade shall have the same length as the old one, otherwise the film material may not be broken when cutting the label, or the label may not be cleaned down.
• When assembling the blade, pay attention to the followings: A. Check if there is a blade groove on the blade for inserting to the blade rest; B. After determination of the blade length, do not operate at the blade edge and its sharp end; C. The blade shall be assembled as per the original assembly direction of the cutter head.
• After assembly of the blade, pay attention to the marks on the belt and put on the belt properly to avoid blocking of label before normal operation.
• Be careful to dismantle the blade and avoid getting hurt by the blade. When dismantling it with tools, the hands shall be away from the blade area. Hold and tighten the belt with the left hand before dismantling blade press plate screw. Pay attention to properly tighten the press plate so as to avoid deformation of the press plate.
• In case the blade angle of each unit is abnormal, or there is abnormal noise, please notify this company for troubleshooting.
