ABSTRACT
Bottles are usually manufactured and filled at two different plants. Let’s say Bottles
are manufactured at 500bpm and if we use manual labour to unscramble the bottles
for filling, the output will be 60-80bpm at max. This creates a bottleneck. In order to
remove this problem, Automation of Unscrambling process is a necessity in the
packaging line industries. The intention of this project is to create an integrated
Unscrambling machine using basic mechanical approaches. The functions to be
incorporated in our machine are Unscrambling, Orientation and Air-rinsing – All this
in a compact & user-friendly machine. The Usefulness and the Economical advantage
of the Rotary Unscrambler has a great future scope for Commercialisation.

1.1 PROBLEM DEFINITION
Going back 15 years, most of the bottling companies would use depalletizing
systems to introduce empty bottles to the filling line. At that time, the 500 ml water
bottles were in the 23–28 gram range. As lightweighting began in the late 1990s,
depalletizing of bottles proved to be inefficient with fallen bottles being a significant
problem. Bottle unscramblers were introduced to eliminate the problem of trying to
maintain bottle orientation off the depalletizer. With an unscrambler it didn’t matter if
the bottles fell over during the depalletizing process. From the depalletizer, the bottles
would be conveyed in mass to the unscrambler, which had the responsibility of
orienting the bottles in an upright position.
Let’s say Bottles are manufactured at 500 bpm in a Mineral bottled water
company and if they use manual labour to unscramble the bottles for filling, the
output will be 60-80bpm at max. This mismatch creates a bottleneck. Manual
Unscrambling output is a very slow tedious process. The Bottle filling plant receives
the bottles in scrambled positions and need to be properly unscrambled and oriented
before filling.
Another problem faced in Manual unscrambling is improper Hygiene and
Inconsistency in Unscrambled output is often faced while manual unscrambling of
bottles, meaning there can be problems like improper placing of bottles in upright
position or bottles falling off from the filling conveyors.
Manual unscrambling does not ensure proper handling and protection.
Despite such Limitations of Manual Unscrambling, the cost of hiringabout 15 laborers
is around 1-2lacs/month.
15. LJIET Ahmedabad | GTU | Mechanical Engineering | Hrishikesh Barad 15
There is a shortage of labor due to increased literacy, which has led to a
declination of blue-collar workforce. This can be used to our advantage by assigning a
skilled worker to operate machines like Automated bottle unscrambler.
Manual Unscrambling and Orientation leads to lower production rates and
decreases Performance.Overall efficiency of the manual process is very less and cost
is higher.Manual Unscrambling Output is only 60 bpm, while automated
unscrambling output is about 600 bpm, which means that efficiency of manual
unscrambling is about 90% lesser than automated process.
Talking about the presently existing automatic unscrambling machines, the
maintenance and initial costs are high. Hang up of bottles during operation of the
drum is a characteristic of some of the presently existing systems.Air rinsing is also
not provided integrated with the common Unscrambling Machines.
16. LJIET Ahmedabad | GTU | Mechanical Engineering | Hrishikesh Barad 16
1.2 TYPES OF UNSCRAMBLERS
A Bottle Unscrambler & Orienter is an automatic, variable speed packaging
machine that receives empty bottles in bulk, then orients, processes, and positions
them onto a moving conveyor for further downstream processing, like filling and
capping. There are several mechanical approaches to bottle unscrambling.
It is designed to provide oriented bottles to the production line, which means
that the bottles are positioned vertically upright in the machine before they reach the
filling line.
There are 4 types of bottle unscramblers:
• Vision Based Unscrambler
• Linear Bottle Unscrambler
• Gravity Based Unscrambler
• Rotary Bottle Unscrambler
The unscrambler I have designed with the help and support of J.P Machines and Tools
will be a Rotary Bottle Unscrambler. The limitations of the former three unscramblers
are discussed on the next page.
17. LJIET Ahmedabad | GTU | Mechanical Engineering | Hrishikesh Barad 17
Limitations of:
• Vision Based Unscrambler: It consists of cameras and sensors that sense the
position and alignment of the bottles but these equipments are very costly and
increas the overall cost of the system.
• Linear Bottle Unscrambler: This unscramble is a horizontally spread
unscramble that requires lots of ground. Thus, increased floor space
requirements is a limitation of the linear unscramble. Linear air rinsing
machines have high space requirements which increases production and
assembly time.
• Gravity Unscrambler: This unscramble uses catchers and vacuum settlers that
are very costly in nature.

1.3 ROTARY BOTTLE UNSCRAMBLER
A rotary unscramble is used for rearranging a plurality of incoming bottles
into a stable conveyable orientation.This machine reduces human resource and can be
made automatic by using design of a Hopper and sprocket mechanism.Automated
Bottle unscrambling is a Simplistic approach to container handling.
Randomly oriented bottles are received in a bulk into the hopper and supplied
to the centrifugal rotating disc by means of a conveyor. The bottles are supplied to the
orienting unit & are set upright in a vertical position, stabilized and placed on the
conveyor.
• If the bottle arrives in the topside down position it will pass through the
orienting guides without any effect.
• If the bottle arrives in the wrong position, it will be turned 180° topside down
when it passes through the orienting guides.
• In the next phase, the bottles are air-rinsed using nozzles that are mounted
below them.
• In the final phase, the bottles are turned 180° in topside up position using
curved guides.

2.3 MARKET SURVEY
There is a great need of fast production in packaging line industries which
requires faster packaging processes too and an Integrated Bottle Unscrambler along
with multiple functions can serve the industries well.
Going back 15 years, most of the bottling companies would use depalletizing
systems to introduce empty bottles to the filling line. At that time, the 500 ml water
bottles were in the 23–28 gram range. As light weighting began in the late 1990s,
depalletizing of bottles proved to be inefficient with fallen bottles being a significant
problem. Bottle unscramblers were introduced to eliminate the problem of trying to
maintain bottle orientation off the depalletizer. With an unscrambler it didn’t matter if
the bottles fell over during the depalletizing process. From the depalletizer, the bottles
would be conveyed in mass to the unscrambler, which had the responsibility of
orienting the bottles in an upright position.
The targeted industries are:
• Beverage companies
• Dairy industries
• Food processing industries
• Chemical industries
• Household products’ manufacturers
• Liquor industries
• Personal care products’ companies
• Motor oil companies
• Edible oil container companies
• Pharmaceutical Industries
• Fertilizer – agro industries
26. LJIET Ahmedabad | GTU | Mechanical Engineering | Hrishikesh Barad 26
Certain pharmaceutical companies require sterilized bottles, which can be fulfilled
by ionized air-rinsing during the bottle unscrambling process. Usually high-tech
vision based unscramble systems are used in such cases.
Average cost of the Unscrambling machines available is about 40 lacs which gives
an output of 500bpm, while the rotary unscrambling machine I will design with the
support of J.P Machines & tools will be more economical compared to the market
prices.

3.1 STEPS INVOLVED IN UNSCRAMBLING
Randomly oriented bottles are received in a bulk into the hopper and supplied to the
centrifugal rotating disc. The hopper stores bottles and prevents production line overload and
disruption, using a deflector and a blower. The orienting element has a curved shape, such
that the bottle is easily released, after it has rotated beyond vertical into a substantially neck
trailing orientation.
The unscrambling process using a rotary bottle unscrambler is an automated process n
which two steps are involved in getting the output of correctly oriented bottles on the
conveyer:
As described in US7270229 the unscrambler in one embodiment comprises of an adjustable
unscrambler having a rotatable circular horizontal floor and a circular wall perpendicular and
adjacent to the circular edge of the horizontal floor creating a bowl shape. At the outer edge
of the horizontal floor, there is a plurality of individual ring members, adjacent to each other
and extending around the floor of the unscrambler, such that each ring member from the
outermost member to the innermost member, exhibits a circumference less than the adjacent
outer member. Each of the ring members is capable of individual movement in a
perpendicular direction with respect to the relatively horizontal orientation of the floor. The
movement of ring members is not completely independent of all the other concentric rings as
will be described later. The floor of the unscrambler is generally horizontal and is also
slightly domed providing a gradually sloping convex floor surface so that when the empty
containers are loaded into the unscrambler, the sloping convex surface of the domed floor
causes the empty containers to gravitate toward the outer wall of unscrambler. Centrifugal
force caused by the floor being rotated also urges the empty containers toward the outer wall
of the unscrambler and assists in maintaining them near the outer wall. Although the sloping
floor and centrifugal force causes the containers to gravitate to the outer wall of the
unscrambler, the containers may end up in a totally undesirable random orientation. In order
for the containers to move forward in orderly fashion towards the chute - which transports the
containers to another device in the packing process, or which helps in achieving co-axial
bottles. All of the containers or bottles must be in some sort of alignment so that they will
fittingly traverse the chute or conveyer without clogging the path.

3.2 PHASES OF UNSCRAMBLING PROCESS
• Input: Loading scrambled bottles on rotating disc of hopper
• Phase 1: Making the scrambled bottles on the hopper coaxial using the chute attached
to the hopper mechanism.
• Phase 2: Orienting all the bottles in topside down position using guides mechanism
• Phase 3: Air rinsing from the bottom using nozzles
• Phase 4: Orienting all the bottles in top side up position using invertor

3.7 Novelty
Our main aim is to integrate two useful processes or functions of Bottle
Unscrambling and Air rinsinginto one machine.
For this, all the bottles are first inverted into topside down position and rinsed using a
burst air from nozzle and then are oriented into topside up position, using the guide
mechanism. This saves crucial processing time and increases productivity.
The second innovation is the very low space requirements of the machine due
to a compact structure. The above motor is set in clockwise direction while the lower
motor is set in anti-clockwise direction to speed up the process.
