AUTOMATED CONVEYING SOLUTIONS

Palletizing Robot

The stacking robot replaces manual labor for material handling and stacking, greatly reducing manual labor intensity and improving the overall efficiency of logistics warehousing. To prevent collisions, injuries, or other safety accidents between robots and personnel, install safety light curtain in the working area of the stacking robot to improve the safety of the working environment. When a person or object enters the light curtain area, the light curtain will immediately detect and trigger corresponding safety measures, such as stopping the robot's movement or triggering an emergency stop. Before stacking the goods, high-precision measurement light curtains are installed to obtain the length, width, height, or volume information of the goods. According to actual demand, the height, width, depth, and stacking method of the goods can be set and transferred to the control system of stacking robot.

What is the main application of measurement light curtain in warehousing logistics？ 

In logistics and other industries, the measurement of product size and volume has been a very common and necessary work. The measurement light curtain can automatically measure the tracking detection of the objects on the packaging line, and can online detect and measure the volume and area of the packaging box.

The high-precision measuring light curtain can be easily applied to the detection and measurement of the overall dimensions of objects in production lines, assembly lines, logistics lines and packaging lines, such as the measurement of the length, width, height and volume of objects, and can also be used for single application or measurement of unilateral products. Secondary programming can be used to realize the data transmission that customers want to show.

Safety light curtain and sensor with muting function

Installing a safety light curtain at the entrance and exit of the logistics conveyor line can detect people or objects entering dangerous areas. Once someone enters, the system will immediately stop the operation of the machine to prevent accidents. However, in some situations where conveying materials or feeding intelligent cars frequently enter and exit, the system frequent operation caused by material and cars will greatly reduce production efficiency. In this case, we can use the muting (also known as "shielding") function to temporarily automatically stop the safety function of the safety light curtain during the passage of objects, while still being able to reliably detect when personnel pass through, achieving "separation of people and vehicles"

Conveyor line object detection

Conveying is one of the key links in the logistics project. How to realize fast and accurate detection of the goods on the conveying line determines the efficiency of goods warehousing and delivery. The sensor installed on the conveyor line can monitor the position of goods in real time and effectively save manpower for handling. Reflective photoelectric sensors have become the industry's preferred choice due to their high cost-effectiveness and stability. In the conveyor line, install mirror reflective sensors on conveyor belt to detect whether the goods have passed through. If goods pass by, the beam of light is blocked, triggering a output response.

PF21 photo sensor main application on conveyor belt system

In the whole storage chain, automated warehouse is a very important part. It is necessary to carry out the sorting, conveying and warehousing of a large number of goods every day. As an indispensable "sensing organ" in the logistics industry, G-TEK PF21 series photoelectric sensor products are applied in automated warehouses, which not only save a lot of labor and time costs, but also make the warehouse operation more efficient.

Packaging industry: 
1. At the inlet of packaging machinery, detect whether objects are present/in place.
By installing diffuse reflection PF21B or (or directed PF21T) at the feed inlet, the light beam is reflected when an object passes by, triggering a photoelectric output response.

Stacker applications

The stackers are the most important lifting and transportation equipment in three-dimensional warehouses. They are mainly used to run along the tracks in the alleys of high-rise shelf warehouses, and then store the goods located at the lane entrance into the cargo compartment. When the goods in the compartment are taken out, they are transported to the lane entrance to complete the inbound and outbound operations.The sensors such as photoelectric sensor , distance sensor, lidar sensor are used at stacker to detect the position of goods , distance acquisition for positioning and avoid collisions with the stacker.

What is the role of long-distance laser ranging sensors in tunnel stacker?

With the increasing level of automation in the logistics field, various information technologies such as optoelectronic technology, computer technology, and control technology have been widely applied. Among them, laser detection technology, with its advantages in ranging, positioning, and other aspects, has played a key role in equipment such as tunnel stackers and automatic navigation equipment, and actively promoted the improvement of the overall performance of the logistics system.

How to achieve positioning of tunnel stacker？

1 Address recognition sensor
During operation, the stacker crane always travels along a fixed track, so it is possible to install certain sensors on the stacker crane body and cooperate with the installation of certain mechanisms on the track. This way, each time the stacker crane passes through these mechanisms, the sensor changes can tell which track area it is currently located in. In the horizontal direction of the stacker crane, this sensor is called an address recognition sensor, and the mechanism installed along the track is called an address recognition chip. Due to the need for accurate positioning of the stacker crane in the horizontal direction, including the location of goods to be stored and retrieved, as well as the position of the conveyor at the entrance and exit of the warehouse, and the corresponding horizontal position of each cargo compartment on the shelf, fixed address plates are installed on each cargo compartment and conveyor position along the track direction. Each time the stacker crane passes through these address plates, the sensor will change the signal. The stacker crane starts running from the starting point, and the number of sensor changes will vary, You can know which cargo compartment the stacker is currently located in, and which two cargo compartment positions are between.
