Choosing the right open-mouth bagger can be a challenge when you’re confronted by the many options available on the market. In order to select the equipment best suited to your needs, consider the following six factors to ensure you make the most informed decision.
1. Type of bags’ material

Paper bags, plastic bags: The shape and composition of the bags you use influence the type of bagger you need. Some bags are very simple to use, others require more complex handling, while still others are comparatively fragile. By understanding your material and the bags you’re handling, you’ll be able to make a smart decision about the bagger you need. Some baggers are designed to handle a specific kind of bag—baggers that incorporate fault-detection technology for porous bags, for example—while other baggers are versatile enough to handle different types of bags. There are different types of bag holders, as well. Don’t underestimate the impact of your bag on your choice of open mouth bagger.

2. Type of product material

What do you bag? Knowing the characteristics of the material you’re packaging will help you choose the perfect bagger. You also need to understand how the packaging process itself affects your material. Does the material need to be deaerated? Is it free flowing or powdery? There are different types of bagging technology for different materials, such as bottom-up fillers for extremely volatile materials. Among open-mouth baggers, some more versatile and some that are more specifically suited to a particular material. Also keep in mind that there are engineering options that can be incorporated in your bagger to optimize the handling of your specific material.
3. Production capacity

Do you need to run four bags per minute or 36? Desired output is one of the most important factors to consider in choosing a bagger. And if you plan to expand production capacity in the future, be sure to choose an open mouth bagger capable of handling more output than you currently produce.

4. Automation objective

What’s the next step for your business? Are you planning to automate your packaging line? It’s an important question that needs to be answered. Depending on your answer, there are many options, from a manual bagging line to a fully automatic line with robotics and additional technology. You can choose from a range of options that accommodate different bag sizes and different materials, from manual adjustment for different bags to fully automatic adjustment. Then there are communication systems, networks, remote access for customer support, data transfer to your actual process controls, and more.
What is your ultimate goal? If your goal is to automate in the future, consider these options proactively. Planning ahead to reach your goals in phases may include upgrading your packaging line in multiple steps, but you need to have this in mind from the beginning in order to select the equipment that’s best suited to help you implement your vision.

Firstly, look at the operation of your hoods. If your system in not a new installation then you should have a baseline of how your hoods should be functioning. If you have a more fugitive dust than normal escaping than this is an indication that the flow in that hood or your system is lower than normal and the system not working correctly. A good marker on whether or not there is more fugitive dust is if there is dust piling up on adjacent flat surfaces. If there is, then the hoods are leaking.
Secondly, check is inside your ducting. The system should have been designed so that material travels at the optimal speed and the dust does not settle out in the ducting. If you have dust settling in your ducting then this is also a good indication that your system is not running as it should.
Finally, see what is coming out of your dust collector into the collection device or into the recoup system. If the system is not discharging anything, than one of two things is happening. The dust collector is either not collecting any dust (which is why there is so much fugitive dust at the hoods) or the material is not emptying off the filter media. To tell which is happening check the dust collector differential pressure gauge. This is an indicator of how clean or dusty the bags are the dust collector. If the pressure is much higher than the normal operating pressure than likely the material is building up inside the dust collector.
These are a few fast ways of checking to see if your dust collection system is functioning as it should. There are many reasons for the above to be happening, but they all give lead back to the same place: issues with the dust collection system. These issues will require further investigation to get to the bottom of the dust collector.

With the evolution of European directives and safety regulations in different countries, the safe operation of machinery has become an important concern across all industries. The best way to ensure user safety is to implement risk assessment and reduction during the equipment’s design phase, as recommended by ISO 12100. The design must adhere to appropriate standards and current best practices to ensure that equipment will protect the user’s safety and health.
Here are the most relevant principles to keep in mind during the design phase:
1- Incorporate risk reduction methods with respect for the hierarchy of their effectiveness

Risk reduction follows a logical path that starts with planning an inherently safe design. For example, reducing the pressure needed to activate a motion that does not require high pressure to begin with helps to protect the operator without incorporating additional protective measures. Then, the next logical step along the safe-design pathway is to consider which safety devices are most appropriate for the application.
2- Select the appropriate safety devices

Safety devices such as switches, relays, programmable controllers, presence-sensors and others must be chosen according to the risk they are intended to reduce: The greater the risk, the greater the performance that is required of a device. Reliability and diagnostic coverage are two important parameters of a safety device’s performance. Choosing high-performance devices avoids diminishing or losing a machine’s safety function during its life cycle.

3- Inform users of residual risk

Even if the goal of safe design is zero risk, achieving that objective is impossible. Despite implementing measures that reduce risk to an acceptable level, human error leading to misuse of machinery may cause injury. Therefore, the user must be informed of actions to take or avoid. The user’s manual, visual or audible signals and pictograms all help the user to be aware of risk. These aids also can be used by a manufacturer as part of employee safety training.
4- Stay alert for new safety standards

It is important to stay abreast of new standards for equipment safety because best practices are constantly evolving.

Even if pallet wrapping is the last step in your packaging line, it’s one of the most important parts of the process. Keep in mind that your product needs to be moved from one place to another without being damaged. The better your equipment wraps and protects your product, the greater ROI that product can deliver.
There are three main questions to answer to make sure you choose the pallet-wrapping technology best suited to your needs:
1. How many loads are you wrapping right now and how fast, and what’s your goal for this rate?
2. What kind of pallet loads do you have? Boxes? Bags? Irregular shapes? Fragile or unstable?
3. What is your budget?
Now that you have the answers, let’s take a look at the options:
Turntable

This stretch wrapping system places a load on a turntable that rotates to dispense the wrapping film. It allows you to wrap up to 45–55 loads per hour (depending on load height) and consistently maintains the correct film tension, which is key to successful stretch wrapping. A turntable wrapping machine is a good option for very stable loads and a low-to-medium production rate.
Rotary arm

The rotary arm stretch wrapper uses an overhead arm that rotates around the load to apply the film, eliminating the need to rotate the load and allowing high-speed wrapping of lighter, fragile , heavier and unstable loads. It’s designed to maintain precise, consistent film tension and can replace the output of up to five turntable stretch wrappers, with a production rate of up to 95 loads per hour.

Stretch hooder

Stretch hood technology is universally applicable because it can secure a wide range of pallet loads. This type of wrapping system is costlier than rotary arm or turntable equipment but optimizes product safety by protecting against humidity, UV and other weather threats as well as against the danger of cargo shift during transport. It’s the best choice for manufacturers who need their product to be visible on the pallet, because stretch hooding technology produces a transparent hood. In addition to ensuring product visibility, this technology minimizes film usage. Stretch hooders produce the highest production rate, wrapping up to 100 loads per hour.
Automation

In addition to the three types of pallet wrappers available, this equipment is available in varying degrees of automation: manual, semi-automatic and automatic. Choosing the extent of automation that’s right for you depends on the packaging output you need to handle and your budget. Manual wrappers require an employee to apply film manually, a level of automation that works best in low-output settings. Semi-automatic machines include turntable wrappers and rotary arm machines that wrap automatically, but require an employee to use a forklift to place the unwrapped load and pick up the wrapped one. Fully automatic equipment uses conveyors to deliver loads, which then have wrapping film automatically applied, cut and sealed. Fully automatic wrappers are ideally suited to high-output packaging.

Check the sensor wiring is correct, open the control cabinet power and warm-up for 15 minutes before debugging. In this paper, the maximum weighing of 100kg, sub-degree value of 0.2kg, 90kg quantitative and accuracy level to meet 0.2% of the technical requirements as an example are as follows:
(1) partial load adjustment for Weighing Packing Machine
Will be 10kg weight, respectively, concentrated placed in weighing hopper two load-bearing point. When the indicator shows “positive”, the sensor output should be adjusted in the direction of lowering; when the indicator shows “negative”, the sensor output should be adjusted to improve the direction. For example, when the output of the L / C-1 sensor is reduced, a fine set of resistors (original value of 10 ohms) related to L / C-1 is rotated to the left by the same amount of rotation.
(Clockwise) resistance decreases, the display value increases (marked as “plus”);
Rotate left (counterclockwise) The resistance increases and the displayed value decreases (“minus”).
Note: If you rotate the trimmer resistor, if the amount of rotation of each group is not consistent, it will make adjustment difficult. Therefore, the fine-tuning resistance of each group of sensors should be the same as the rotation. The absolute value of the load-bearing point error is not more than 10g for the pass.
(2) Weighing adjustment for Weighing Packing Machine
Follow the steps of the weighing controller manual to perform the weighing adjustment. In the test, from 0 to the maximum point, respectively, 0kg, 40kg, 70kg, 90kg, 100kg in the order of increasing weight, the error is not greater than 10g, 20g, 35g, 45g, 50g; from maximum to zero 100kg, 90kg, 70kg, 40kg, 0kg in the order of decreasing weight, the error is not greater than the respective tolerance; at 40kg, 100kg two quantitative point repeatability test, each weighing three times, each error is not greater than the respective Tolerance.
(3) parameter setting for Weighing Packing Machine
Weighing Packing Machine needs set more parameters, the following key parameters to commonly used as an example are described below:
A, weighing display controller quantitative value can be set to quantitative target values, such as 90kg and so on.
B, fast-feeding in advance, slow-feeding in advance
When the weight> (set value) – (fast-feeding in advance), stop fast-add, into the slow increase;
When the weight> (set value) – (slow-feeding in advance), stop feeding.
