The process of bottle line consists of many steps that are meticulous and repetitive. Now you see why so many factories across the world have started using machines to handle their packaging process.
To save money, keep workspaces tidy, and cut down on human mistakes, automatic liquid bottling systems are a significant investment. Take a look at the following to learn about the different steps that comprise bottling.
The Process of Bottle Line
Liquid bottling solutions are vital in the process of bottle line for many fields, including the pharmaceutical, cosmetic, and beverage sectors. This article will walk you through the fundamentals of using automatic technology to fill, cap, label, and organize liquid products in bottles.
Step 1. Bottle Filling
Containers are filled with products of varying viscosities using a liquid packing machine. Anything in a liquid state might have a thickness anywhere from extremely thin to extremely watery. Filling a beverage can, and an ointment tube are two very different tasks. Therefore, a variety of filling techniques are necessary.
When selecting a suitable liquid filling machine, considerations go beyond viscosity. Different containers require different filling technologies due to factors such as the product’s chemical compatibility with the container, the size of the product’s particles, the temperature of the packing environment, and necessary filling accuracy.
Bottle Filling Machines for Commercial Use
Liquid filling machines come in several types, which consist of:
Inline Filler
One way to fill bottles of liquid is using an inline filling machine, which works by using a conveyor system. Depending on the production needs, these systems may be adjusted with multiple types of filling nozzles. Different containers and products may benefit from their adaptability, affordability, and flexibility. Many companies select inline fillers because they allow for easy flaw identification, which is especially useful for low to moderate production rates.
Rotary Filler
The rotary liquid filling machine tends to be bigger and faster than the inline liquid filler. With its many filling heads, this machine can fill bottles quickly, allowing them to produce more bottles per minute. Furthermore, bottle capping and cleaning technology are integrated into several rotating machines. Companies seeking to accelerate total production may, however, use either rotary or inline fillers, which are fast and easy alternatives.
Monoblock Filler
Several pieces of packaging machinery may be housed on one structure in a monoblock filling system. Standard components include a machine for filling and machinery for sealing. A star wheel is a common component of monoblock fillers and is used to transfer containers between pieces of packing machinery. The footprint of a single-star wheel is much less than that of lengthy, intricate conventional conveyors. Monoblock systems are a great choice for buildings that are short in square footage.
When it comes to filling, all machines are basically the same. A conveyor carries the container as it moves through an automated system. Once the bottle is filled, the machine is prepared to proceed to the next step.
A liquid filling machine is an efficient, accurate, and time-saving equipment that speeds up the filling process while decreasing the need for laborious human work.
Step 2. Bottle Capping
The capping machine reliably and firmly fastens a metal or plastic cap on a container. A clean work environment, reasonable prices, and fast speeds are all benefits of this.
The cap hopper receives closures like lids, caps, and plugs via a feeding system. After that, the caps are fed into a sorting bowl by the cap elevator. For a more efficient method of delivering caps, a sorting bowl is a useful tool.
Before the caps are set on the capping machine to be attached to the containers, they are all sorted in the sorting bowl. In other situations, a hopper or sorter may be all that is needed to sort caps more effectively.
The wide variety of caps and containers on the market demands various capping machines. From compact, semi-automatic ones to massive, fully automatic ones, their speeds and complexity may vary significantly. You may often see two kinds of cappers:
Single-Head Capper
To fasten lids, a single-head capper system pauses bottles at stations. Even though they are often built to be inline, single-head cappers may also include a star wheel that takes the cap and bottle off the line. Prior to returning the parts to the assembly line, the star wheel fastens the lid.
Rotary Chuck Capper
To seal the containers, a rotating chuck capper applies the caps and then feeds them into the machine. To create a tight seal, the machine spins the bottle and cap.
Step 3. Bottle Labeling
Before you can label the container, make sure the cap is snug and secure. Labeling machines apply labels to containers at constant rates using a conveyor system. Common components include a driving wheel, a reel, and two wheels for labeling.
The driving wheel pulls the label tape from the spool by dragging the label belt. The label spindle rubs up against the container. The tension on the label strips is maintained by the reel’s open-loop displacement switch. The constant stopping and starting of the label belt is necessary due to the close proximity of the labels on the label strip.
In tandem with the container’s and wheel’s motion, the label is affixed to the bottle. To keep up with the conveyor’s speed, the driving wheel starts to accelerate as soon as it reaches a certain point. The machine comes to a full halt when labeling is finished.
Because labels tend to slide a little, they often come with a unique mark and sensor to ensure they’re put on correctly. The driving wheel may compensate for label mistakes by adjusting its location during deceleration.
Similar to filling and capping equipment, labeling systems provide several advantages, such as higher productivity, faster processing times, and aesthetically pleasing results.
Step 4. Bottle Orientation
Orienting the final products is the last step. Containers frequently get mixed up and come in a chaotic form for the packaging procedure. Before packaging the bottles, their orientation must be changed from random to regular.
To keep all the bottles in the same place as they go down the assembly line, a bottle orientation machine is a useful tool. It spins the containers around so they are all facing the right way. The necessary machine type is dictated by the kind of container and the direction in which it must be rotated. Vertical orientation is the only option for many orientation devices.
After vertical alignment, axial container orientation may be necessary in some instances. This stage may be completed using an axial orientation machine or a secondary machine.
For containers like detergent that have handles or openings that aren’t in the exact middle, orientation is a lifesaver. By constantly turning the container’s handle to the left or right, an orientation machine can align the filler nozzle with the off-center opening.
Various non-standard-shaped liquid containers, such as honey bear bottles, trigger spray bottles, and many more, may be handled using orientation technology.
Summary
Bottles go through many steps in the process of bottle line, including setting, cleaning, counting, inserting, capping, sealing, and labeling. Down to filling, capping, labeling, and orienting. There are many methods to optimize a bottling line, such as adding or removing specific machines as required and establishing a direct correlation between the bottling pace and the slowest equipment on the packing line. To get the optimum cost performance, there are so several factors to consider.
