Double Side Sticker Labelling Machine: The Complete FAQ Guide in 2024

Label is an adhesive piece of paper stuck to a bottle, box, medical appliances etc. that holds all the necessary information pertaining to the content held within a container. Available in vibrant colors and designs labels are also used as a mean of advertisement that increases the likeability of the product and attracts customers.

Historians believe that first labels originated in Egypt when artifacts with labels were found during excavation. Till 19th century labels were hand written and pasted manually using glue but with the improvement in packaging and printing technology, printed and self-adhesive labels were introduced in the last century that laid the foundation for the development of first ever sticker labelling machine.

    1.A journey from labels and stickers to the invention of first sticker labelling machine.

    sticker labelling machine

    The first known hand written labels were used on wine bottles and small medical containers around the year 1700 that were handmade and glued to the product using a wooden press. In 1798 advancement in technology lead to two inventions that made label production more efficient i.e. the paper machine and the lithographic principle.

    lithographic principle

    Between 1850 and 1860 colored labels were introduced that increased the likeability of the products increasing their demand and sale.

    demand

    Pietro Cavagnino and Antonio Gatti are credited with the invention of first labelling machine bearing their name in 1955. After mere six years in 1961 they developed CG 61/D; the first automatic labelling machine one of a kind used for labelling bottles. Sales of this machine rose exponentially, particularly in France and Italy where over 4,000 units were sold.

    3.Single side sticker labelling machine vs double side sticker labelling machine.

    Single side and double side sticker labeling machines are two types of labeling equipment used in labelling process having more or less same working mechanism. However, there are few differences between them:

    Single Side Sticker Labeling Machine Double Side Sticker Labeling Machine
    Single Side Sticker Labeling Machine Double Side Sticker Labeling Machine
    These equipment glue stickers on one side of the containers and are called front side labelers. These equipment apply stickers or both sides of containers so are known as front/back labelers.
    They are equipped with one dispensing or labeling head. They have two labeling head for dispensing sticker on front and back of containers.
    Single side labeling has less labeling area which limits the product information display These machines offer more area for presenting product information.
    The running cost of these instruments is low. These require less glue and sticker materials. The cost of running these equipment is high in comparison to front side labelers because they need more adhesives and labeling film.
    The production capacity of these machines is low compared to double side labelling machine. The machine has a labeling speed of up to 150 bottles per minute (BPM). The production capacity of these equipment is a bit high than single side labelling machine. This machine can label up to 300 BPM depending on the product and label size

    The function of label sensor is to detect the gap between stickers. This part transmits signal to control system for halting containers labeling process in case of malfunction.

    Label Sensor
    Unwind Reel

    The labeling film is placed on unwind reel for uncoiling.

    Unwind Reel
    Guide Rails

    These are fixed on the side of conveyors and facilitate the movement of containers in right direction keeping them in place.

    Guide Rails
    Dispensing plate

    The stickers are attached on bottles by the dispensing plate or labeling head.

    Dispensing plate
    Conveyors

    They carry out transport of bottles to different parts via servo motor that provide necessary mechanical energy for driving conveyors.

    Conveyors
    Drive rollers

    These are used for pulling the labeling sticker from unwind reel and keep labeling paper under proper tension.

    7.What is the working principle of double side sticker labelling machine?

    Every part of double side labeling machine works in complete synchronization for efficient labeling of containers. Some steps involved in working of these equipment include:

    double side sticker labelling machine-4

    Sticker Film Loading

    The sticker roll is put on supply plate or unwind reel. Afterwards, the film is unwind and moved across tension rollers for controlling the rotational speed of film roll. The sticking film is placed between the forks of sensors for dispensing labels.

    Feeding of Containers

    The containers are placed on conveyors and are transported to labeling area. Space correcting device is used for maintaining certain distance between containers.

    Labeling

    Optical sensor detects bottles and transmits signal to PLC unit. The PLC unit conveys message to stepper motor for labeling. Dispensing head place stickers one by one on the bottles. Brushes are used for removing wrinkles from labels.

    The correct positioning of labels is determined by label sensors. The labels are applied to both sides of bottles by labeling head.

    Discharging

    Immediately after gluing of labels, the containers are removed by discharge chute. Machine automatically reject inaccurately labeled products by means of sensors which are collected in rejection bin.

    • Keep hands off of moving parts of machine; these include roller, conveyer and axis.
    • Do not wear loose clothing, expose hair, jewelry etc. while operating machine as most accidents occur due to entanglement of loose objects in unguarded moving parts.

    10.How to insert label applicator?

    Some steps for inserting label inserters are as follows:

    First place the labeling roll on the supply reel. The film is then moved around tension rollers to generate tension in the film. This is done to prevent slipping of labels.

    insert label applicator

    If machine is equipped with printers then put the labeling paper between print head and printing pad.

    Labels must be slipped amid bifurcations of label sensors for controlling the dispensing of labels.

    The driver roller and aluminum roller should be in close contact with each other to effectively pull the sticker paper.

    11.How to adjust label sensors and other parts?

    Some tips of adjusting various parts of double side sticker labeling machines are discussed below:

    Label sensors

    • The positioning of sensor must be precise for proper dispensing of stickers on the apex of containers.
    • If sensors are at far right position then stickers will get delayed and will not be glued to containers.
    • If positioning of sensors is at the extreme left then labels will appear quickly from roll and be wrinkled.
    Label sensors
    Conveyors

    • For maintaining proper tension of conveyor belt, undo the screw nut located at the back of conveyor. Tighten the belt and afterwards redo the screw nuts.
    • For reduced nose level conveyor belt should always be in middle.
