Pallet stretch wrapper automatic

Types of pallet stretch wrapper automatic

Automatic pallet stretch wrappers are an efficient way to wrap large and heavy loads and ensure that they are securely and tightly wrapped. Automatic pallet stretch wrappers are used to wrap products on pallets or without pallets for safe shipment or storage. They are available in various models to meet different needs and applications.

• Automatic turntable stretch wrapper: It is a stretch wrapper that uses a turntable to rotate the pallet or product while wrapping it with stretch film. The wrapped pallet is then ejected from the wrapping station, either manually or automatically. An automatic turntable stretch wrapper is easy to use and has high wrapping efficiency.
• Automatic traverse arm stretch wrapper: An automatic horizontal arm stretch wrapper has an arm that extends horizontally across a stationary pallet to wrap it. The horizontal arm moves up and down to adjust to different pallet heights, making it suitable for wrapping products of various sizes. It has a higher wrapping speed than the turntable stretch wrapper, providing greater efficiency in the packaging process.
• Automatic stretch wrapper with pallet pusher: This machine model is equipped with a pallet pusher that pushes the wrapped pallet to a film cutting and attaching unit. It is helpful for operations that have to wrap a high volume of boxes or products per day with either stretchable or non-stretchable materials.
• Rotating disc stretch wrapper: Unlike traditional methods, where items are wrapped by moving them around, this innovation involves moving a circular platform or disc while keeping the item stationary. Rotating discs can reduce wrapping expenses and film waste, particularly for products without bottoms that need wrapping from the base up.

Specifications and maintenance of pallet stretch wrapper automatic

The automatic pallet wrapper machine has many parameters that determine how it wraps products. Some of the essential parameters include the width and height of the wrapping film; the size of the pallet it can hold; the speed at which it rotates, which is sometimes called wrapping speed; and the tension control for the wrapping film.

• Width and height of wrapping film: The stretch wrapper machines come in several sizes, accommodating various widths up to 18 inches (0.46 meters). The required height depends on how tall the pallets are—film heights range up to 80 inches (2.03 meters) or more.
• Pallet size: The pallet dimensions depend on the length (up to 49 inches or 1.2 meters) and width (up to 41 inches or 1.04 meters). Most pallets that need wrapping are between these lengths.
• Wrapping speed: Turntable speed for a rotary pallet stretch wrapper is its linear speed, which ranges from 40 to 120 inches per minute (1 to 3 meters per minute). Higher turntable speeds result in saving more time and higher productivity.
• Tension control: Wrapping tension is a vital parameter in determining how much force is applied to the wrapping film when the pallet is wrapped. The tension can be customized in the stretch wrapper machines, and different constructions require different wrapping tensions. The tension is expressed in pounds and can range from 5 to 30 pounds (2.3 to 13.6 kg) or more.

TLC (tension, length, and control) is a commonly used term in stretch wrapping. Under TLC, tension is the force on the film while wrapping is done. The length refers to how much film is necessary to wrap the unit. Control is how the film's length and tension are controlled while wrapping is done, like in a programmable stretch wrapper.

To keep an automatic stretch pallet wrapper in good working condition, some maintenance tips can go a long way in keeping the machine in tip-top shape. Regular cleaning is an essential maintenance tip. It helps remove any film residue or debris that can affect performance.

Another helpful maintenance tip is lubricating moving parts like bearings, rollers, and chains. Careful inspection of electrical components and cable connections can also prevent stretching wrappers from malfunctioning.

Since some machines are automatic, it is necessary to check the hydraulic fluids from time to time. These fluid levels should be optimal for machinery to function correctly. Gear and motor should be examined occasionally so that any abnormal noises or signs of wear can be detected early, preventing further damage and eliminating the need for costly repairs.

Scenarios of automatic pallet stretch wrappers

Stretch wrapping pallets with the help of an automatic pallet wrapper is an essential step before shipment. The automatic pallet wrapping machine can guarantee consistent and high-quality wrapping, making it perfect for products in the retail supply chain and warehousing.

Around 30% of products may get damaged on a single journey, according to statistics from a well-known pallet wrapping manufacturer. Products may arrive at their destination with a clump of them scattered in the container rather than on the shelf if they are not properly wrapped and protected. Using an automatic wrapping machine reduces the likelihood of products being damaged in transit by a maximum of thirty per cent and extends the shelf life of products by up to one year if they are correctly wrapped. This has the potential to save businesses millions of dollars.

Automatic stretch wrap machines are almost always required in industries that use pallets to store products. Some of these industries include construction, food and beverage, pharmaceutical, logistics and transportation, and retail. In addition to these industries, several others use automatic stretch wrap machines.

Instead of being manually wrapped with stretch film, which is a type of plastic that is pulled tightly around the pallet, automatic stretch wrapping machines wrap pallets automatically. Automatic stretch wraps work extremely well and should be the preferred choice in high-volume wrapping situations. They are built to wrap a lot of pallets per day.

While manual stretch wrapping machines are more affordable, they are not ideal for businesses that wrap large pallets regularly. Manuals will not provide adequate safety and security for products on pallets or the number of wraps that automatics do. Automatic stretch wrapping machines can wrap up to 150 to 200 pallets per hour, while manual wrapping machines can only wrap 20 to 30 pallets per hour. Automatics are faster and more cost-effective when high-volume wrapping is needed.

How to choose pallet stretch wrappers automatic

When purchasing pallet stretch wrapper automatics, buyers should consider several factors such as packaging film types, packaging speed, load stability, adaptability, control system, safety features, and maintenance requirements.

People should first determine the types of packaging films compatible with the stretch wrapper they want to purchase. They should consider the machine's compatibility with different packaging film types, like stretch film, shrink film, or stretch hood film. Also, they should consider the film's width and diameter that the wrapper can accommodate.

Another crucial factor to consider is packaging speed. Various stretch wrappers have distinct packaging speeds. For instance, turntable stretch wrappers are faster than rotary arm stretch wrappers. The turntable stretch wrapper rotates the pallet and the packing film around it, while the rotary arm revolves around the pallet. When purchasing, choose a stretch wrapper with adequate speed based on the packaging volume demands.

One may opt for a stretch pallet wrapper with load stability if they regularly deal with unstable loads, for instance, pallets or packages with odd shapes. Go for stretch wrappers with extra securing features, like strapping or dunnage, if load stability is a concern.

A stretch wrapper that can accommodate different pallet shapes, heights, and sizes is ideal if adaptability is needed. Consider a stretch wrapper that can adjust wrapping parameters like film tension, speed, and height if adaptability is essential.

The stretch wrapper’s control system can also influence the decision. Many stretch wrappers have automatic and semi-automatic modes. When in the semi-automatic mode, the operator triggers the machine, while, in the automatic mode, the machine performs a wrapping task automatically without any operator assistance. Choose a stretch wrapper with an easy-to-read control system depending on the required skill level and other factors.

When purchasing stretch film wrappers, consider the safety features like emergency stop buttons and interlocks. These features promote operator safety, especially in fast-paced environments.

Lastly, the maintenance requirements demand consideration. Because of their mechanical complexity, stretch wrappers need maintenance. Buyers should choose machines that are easy to access and service that have clear maintenance instructions.
