What is Palletizing Machine
A palletizer is a machine that provides automatic means for sorting, transferring and stacking cases of goods or products onto a pallet; usually at the end of a manufacturing line. If you want to know the specifications and prices of Palletizing Machine, please contact us!
Advantages of Palletizing Machine
Increased Efficiency
The main advantage of using palletizing machines is their ability to increase the efficiency of production to a higher level. These machines are able to work without any breaks and achieve a higher volume of palletizing work in less time than human workers. Difficult palletizing patterns can be done easily with the help of pallet stacking robots, which are mostly challenging for humans to complete.
Improved Safety
Palletizing is a physically demanding task that can lead to injuries such as strains, sprains, and back injuries. Robotic palletizers reduce the need for human workers to undertake these jobs, minimizing the danger of injury in the workplace.
Increased Productivity
Robotic palletizers are capable of functioning continuously, meeting the demands of a busy manufacturing environment. Higher output levels, quicker turnaround times, and more effective resource use result from this increased productivity.
Consistent Quality
Palletizing robots can maintain the consistent quality in the palletizing process. They can always keep the palletized product load in a neat and uniform manner by placing them in the same orientation on every pallet.
Flexibility
Robotic palletizing equipment is easily programmed to handle a different range of products of various sizes and palletizing patterns. Without the assistance of manual adjustment, they can quickly and effectively switch between random products and palletizing patterns.
Cost-Effective
Although purchasing a palletizing robot is a bit expensive, the long-term benefits always outweigh the expenditures. Some of the main advantages are that palletizers can reduce labor costs, boost productivity, and reduce human injuries, which help save the company a lot of money in the long run.
Reduced Film Consumption
Automating your pallet wrapping process with machinery usually reduces the amount of film used considerably and can therefore also save on costs. Machinery can exert a greater stretch capacity on pallet wrap film than an individual can when handling it manually, whilst still maintaining its integrity. This allows you to achieve more wrapped pallets per each roll of stretch film your business uses. Our range of stretch films have a stretch ratio of up to 400% versus standard hand wrap films which can be far, far less. Using significantly less stretch film equates to a cost saving as you will need to purchase fewer rolls.
Labour Savings
Cost savings can also be achieved in terms of labour as the equipment can match speeds that rival the work capacity of several operators, representing a short payback on your investment. Additionally, total consistency is guaranteed when using a stretch wrapping machine compared to a hand-wrapping set-up. The equipment ensures that every part of the pallet is wrapped adequately and evenly, avoiding areas of the pallet being overlooked or more film being used than is required.
Operator Health and Safety
Automated stretch wrapping equipment can be beneficial for more than just your production efficiency and your profit margins. Manual pallet wrapping poses several risks to your operators from hazards associated with bending, lifting, repetitive movements and trips and slips. By trading the heavy lifting for the touch of a button, these common health and safety pitfalls can be avoided.
Smaller Footprint
Palletizing robots take up a fraction of the space when compared to it traditional palletizing system counterpart. Whereas an automated palletizer system is conveyor-based, palletizing robots require far fewer conveyors which allows them to fit into small-scale facilities where space is at a premium. By switching to a robotic palletizing system, you could free up floor space currently utilized by a large conveyor-based system and regain room in your warehouse to grow and expand in the future.
Scalability
Demand isn't a consistent flow for most companies. Robotic palletizing systems make it simple for you to scale back the workload during the slower production periods. Alternatively, they also allow you to ramp up production in order to meet an increased demand. This process is much easier with a robot than the traditional systems, where you would need to turn off entire lines via a time-consuming and difficult process.
Types of Palletizing Machine
Floor-level Palletizers
These palletizers typically have an infeed level of 30" to 36". As products travel through the infeed conveyor, they are oriented by a turning device or conveyor before being moved to the row-forming area. Products are arranged into rows until a row is complete. This row is then transferred to the layer-forming area. Once a full layer is formed, it is pushed forward to the stripper plate, where the products are adjusted in height and placed onto the pallet or the previous layer. The stack remains stationary during the load-building process, which continues until the pallet is fully loaded. The finished pallet is then transferred to the discharge conveyor, usually set at an 18" discharge level.
Floor-level palletizers are generally less expensive and simpler to construct compared to high-level palletizers, and they require less floor space. With most components positioned at floor level, maintenance is quicker and more straightforward due to easy access to the parts. Additionally, operators can easily monitor the machine's operation since most moving parts are at eye level. When integrating with other equipment in the packaging line, floor-level palletizers are ideal because they do not require elevation changes for the infeed conveyor, making them well-suited for pairing with packers and sealers.
High-level Palletizers
High-level palletizers typically have an infeed level ranging from 84" to 124" or more. Like floor-level palletizers, products are transported by the infeed conveyor to a turning device or conveyor that rotates them into the correct orientation before moving them to the row-forming area. Products are arranged into rows until a row is complete, then transferred to the layer-forming area. Once a layer is formed, it is moved into position on the pallet or stack. The main distinction from floor-level palletizers is the ability of high-level palletizers to raise and lower the stack with each layer added. After the stack is completed, it is lowered onto the discharge conveyor, which is usually set between 18" to 30". In many installations, a raised operator platform is built alongside the machine for easier operation and monitoring.
High-level palletizers are ideal when there is sufficient space for an inclined conveyor, allowing the packer and sealer to be positioned at a distance from the palletizer. Compared to floor-level palletizers, high-level machines offer higher throughput relative to their size, making floor space utilization more efficient. They are capable of handling throughputs of approximately 40 to 50 items per minute, regardless of the discharge elevation of the packer or sealer.
Conventional Palletizer
Conventional palletizers make use of mechanical systems for operation and have been a staple in packaging lines for decades.
They work well in settings where products are uniform in size and the volume of goods to be palletized is high. These machines are designed for speed, efficiently organizing and stacking products to maximize throughput.
Cobots (Collaborative Robots)
Cobots are a subset of robotic palletizers designed to safely work in close proximity to human operators.
They are particularly useful in environments where manual and automated processes need to integrate with each other.
Cobots are compact, easily programmable, and can be adjusted for different tasks, making them a versatile tool in the packaging process. Their design prioritizes safety and efficiency, allowing for a collaborative workspace where robots and humans can perform side by side.
Articulated Arm Robots
These robots are known for their flexibility and range of motion, capable of performing complex stacking patterns that require precise movements.
Articulated arm robots can handle products of different shapes and sizes, from small, delicate items to larger, bulkier goods. Their advanced design enables them to quickly adapt to different packaging needs, reducing downtime and increasing productivity.
This adaptability makes articulated arm robots a valuable asset in modern packaging lines, where demand and product specifications can change quickly.
How To Choose Palletizing Machine
Solutions and Simultaneous Operations
The effort to reduce secondary packaging is accelerating, which is having a significant impact on the design of palletizing equipment. The trend is driving hybrid palletizing solutions involving both conventional and robotics technology. Simultaneous operations are also becoming more prevalent, such as palletizing and stretch wrapping in a single integrated piece of equipment. Increasing numbers of package applications are better suited to fully automated equipment; thus, the need for package handling flexibility involving quick "tool-less" or fully automated technology.
Weigh Total Cost of Ownership and Future
ROI tends to favor conventional palletizing equipment at very low and very high speeds. Despite varying opinions, proponents of robotics claim to handle a wider range of SKUs and package types, and cite applications involving more than 60 cases (or multipacks, etc.) per minute. Beyond speed and costs, consider your application. For example, when one bottler's conventional palletizer was damaging lightweighted bottled-water multipacks, the company chose robotics for gentle handling and newfound sustainability cost savings.
Safety
The safety of palletizing equipment is of primary importance. These are large powerful machines that move heavy cases, bundles, and pallets at high rates of speed. The vendors must adhere to OHSA and ANSI requirements in the design of their equipment. If the system employs robots, additional OSHA regulations are in effect. Respect of these safety features is the responsibility of the end user as well as the use of good LOTO procedures.
Consumer-level developments and graphics technology may affect your machine decisions.
Warehouse stores are driving more display-type pallet loads and cases. In turn, this drives the need for graphics-out palletizing, often requiring the placement of tier sheets between layers and corner boards to improve load integrity and warehouse stackability. It may also require you to think about hooding versus stretch wrapping—a single layer of hood film will show off graphics and bar codes more easily.
Costs
Newer, lighter-weight packages with little or no secondary materials, combined with the need for greater flexibility and automated changeover are driving up the cost and complexity of palletizing equipment. It is also resulting in an accelerated use of robotics technology. Be sure to consider all bottom-line costs before purchasing equipment; assess if the investment proves its worth in empowering you to handle higher-quantity outputs and lower per-pack weights.
Stability
This capability should be planned up front because it is complex and expensive to add later. Think about how you supply slips or tiers to a palletizer; if those sheets aren't straight, a robot may not know that, and the placement might be incorrect.
Flows and Orientations
Think about how bulk pallets of sheets and empty pallets will be supplied to the palletizing equipment. If those sheets are not straight, the machine (or robot) will not know the difference and the sheet may be placed in the wrong location. Asking the vendor about options to keep the sheets straight or separate the sheets if more than one is picked for the stack may help avoid headaches in the future.
Existing Controls Standards
Keep your controls constant and up to standards on all palletizing equipment. With the increase in globalized manufacturing, you often need to meet international standards, and you should always have independent testing done to make sure your potential palletizing equipment is in compliance.
Component of Palletizing Machine
Beams
This component supports the end effector and allows linear movement along a single axis. Motion is provided by servo motors through mechanisms such as rollers and rails, rack and pinion gearing systems, or chain and sprocket drives. Beams are commonly found in Cartesian and gantry palletizers.
Columns or Mast
Mounted on a fixed base, this part supports the beam or arm and end effector assembly. It uses hydraulics, servo motors, or chain drives to enable vertical movement, allowing the connected components to move up and down.
Arms
Typically consisting of two linked segments, arms enable the end effector to move horizontally by rotating, extending, or folding.
Joints
These components provide rotational movement between various parts of the palletizer system. The number of joints can vary depending on the required versatility of the system.
End Effectors
Often referred to as end-of-arm tools, end effectors are crucial in robotic palletizer assemblies due to their versatility compared to conventional palletizers. They are responsible for picking up and placing products in the correct location and orientation on the stack. Designed to handle a variety of products with a single tool, they can also be equipped to retrieve pallets from a pallet rack or to pick slip sheets, tier sheets, or top caps from a dispensing rack. These features enhance the robot's functionality and efficiency.
Following are the most common types of end effectors.
Clamps
Clamps lift products by gripping the sides, enabling the handling of multiple items with the same orientation simultaneously, which speeds up throughput. They are particularly useful for stable products or those not suited for vacuum handling, such as HSC (cases with no top) or display cases.
Forks
Fork tools are used for delicate, unstable, or special cases like HSC (cases with no top) or warm/hot shrink-wrapped products where gentle handling is necessary. The tool features cutouts that allow it to slide underneath the product for lifting and cradling. A clamp can be added to the fork tool for added stability during movement.
Fingers
Finger end effectors are mechanical tools that open and close in two directions, providing support underneath the product. They are commonly used for handling bags.
