PLC precision positioning palletizer
1) it is easy for the clip to turn 90 degrees, just buy a rotating cylinder with fine-tuning angle on it, and the error is very small after adjusting it.
2) make a block on the chain and install the sensor to make sure that A goes to the dead position so that the position of An is accurate.
3) if the distance from A to B is not far, the error can be 0.1mm by using the cylinder to match the dead limit. If it’s too far, use the synchronous belt with the servo. The error should be within 1mm, but the tightening should be designed and the backlash of servo motor gearbox should be considered.
Production line of palletizing robot
After the workers have finished packing the product, they enter the conveying line 1, and the product is transported to the box sealing machine, and then through the conveying line 2, there is a positioning device in Line 2, which can also be called the positioning baffle (which has been successfully applied in the Wa production line). This device and the positioning plate can complete the rotation and positioning of the box, which can be positioned on the left and then transported to the buffer zone 1, which has a booster device. The device can properly transport the box to the free space and push the full tray to the buffer zone 2. Above the buffer zone is a code stomping robot. Through the robot sucker, the robot elevates 15 boxes (15 in small bags and 8-10 in boxes and listening) vertically and runs horizontally to avoid the safe passageway. The width and height are 2 meters. After passing through the safe channel, it is placed vertically in the yard stomp area, and the front positioning bezel has rotated the box, so the manipulator does not need to rotate, after placement is completed. Return according to the original path, after completing the 10-story code stomping area, it will be forked away by the forklift and the idle code plate will be placed. The front buffer 2 code disk is empty after the box body is removed, which can be manually removed and placed in buffer 1 when the buffer 1 code disk is delivered.
The system is also equipped with an emergency stop button, which can be stopped manually or automatically; a raster safety system is installed within the working range of the robot support frame, and the alarm signal light is on in the fault or abnormal condition, and the system stops emergency. the system can continue to run after the alarm is excluded in the manual state; it has automatic memory function and can continue to complete the work after a power outage or failure.
The drawing of the transmission line is as follows:
Operational efficiency calculation:
According to the sealing time of 15 boxes / min provided by the customer, if a grab box takes 4 seconds to run, the product is lifted, transported and placed back in accordance with the path. because the lower part is the walking area, the differential compensation movement of the guideway can not be applied, but can only take a straight line. It is possible to use such a working speed that is not completed, and it is very unsafe. according to the way the box is transported as a whole, it takes 60 seconds for a code disk to fill up. In these 60 seconds (the other two can have 32 seconds-40 seconds, can code 8-10), there is plenty of time to complete boosting, grab lifting, conveying, placing and returning.
The above is the product transportation mode of box packaging, please refer to the effect drawing for the specific process.
The production cycle of large bag products is 15 seconds per bag, so directly complete a single yard stomp transportation, the time is also very sufficient, mainly because the load is not large, so the running speed can be improved.
To sum up, the efficiency of handling and palletizing is greatly improved by using Shenyang Ding cold mechanical and electrical palletizing robot. Save a lot of manpower, greatly reduce the cost of labor. The cost of the robot can be recovered after one year of operation. The robot has been operating under normal maintenance for at least ten years. With the rise of a large number of fully automated palletizing production lines, this palletizing system will have a wider market prospect and development potential!

For random pallets, palletizing robots are the only option. In spite of this, robot loading also faces many problems, and it will be more difficult to produce at a higher speed.
A robotic palletizer that handles random loading requires special software, which connects the robot palletizer to the rest of the production line, which is a huge step forward.
A robot used to build random pallets can be integrated into the factory’s warehouse management system (WMS). Ideally, it would be the front part of WMS, working in coordination with warehouse software to produce hybrid pallets.
Sophisticated software can also meet the need for immediate shelving. Generally speaking, this means that after the product is stacked, the labels of some or all of the packaging containers must be facing outward. Robotic palletizing equipment is also an option for another demanding application: palletizing in a frozen warehouse. In the field of consumer packaging, handling boxes in a frozen warehouse is one of the most difficult tasks. Workers have to work frequently to keep warm, which indirectly reduces work efficiency and increases labor costs.
In a frozen environment, automated random access palletizers are not the right choice, as most automated random access palletizers use compressed air tubes that freeze in cold storage. Compared with the automatic palletizer, the size of the palletizing robot is more compact, which is particularly important because the space in the frozen warehouse is very precious. In spite of this, there are some problems in the application of robots in frozen warehouses. Some suppliers have begun to design special palletizing robots for frozen warehouses.
When using a palletizing robot, there is also an important thing to consider, that is, how to grasp a product. Vacuum grip is the most common manipulator arm end tool (EOAT). They are relatively cheap, easy to operate, and can effectively load most of the load. However, in some specific applications, vacuum grips will also encounter problems, such as porous matrix on the surface, flexible packaging in which the content is liquid, or uneven packaging and so on.
Other EOAT options include a flip grip, which clamps the sides of a bag or other form of packaging, a fork grip, which is inserted into the bottom of the package to lift the package, and a bag grip, a mixture of flip and fork grips, whose fork covers the bottom and sides of the package.
Other combinations of basic EOAT types are also possible. A beverage Packer has difficulty palletizing a corrugated tray that is full of bottles and shrinks. The vacuum sucker will pull the film off the tray.
What is the supporting palletizer on the cement brick production line?
The palletizer is the palletizing equipment in the fully automatic unfired brick production line. The manipulator and the main body of the fuselage respectively realize 360 °horizontal rotation in three-dimensional coordinates through the control center, the manipulator can rise and fall vertically and can grab a variety of special-shaped building products into square palletizing, and the weight balance method is adopted to grab a palletizing robot with a code load of up to 400 kilograms. it can fully meet the heavy-duty palletizing needs of blocks (bricks) and other related industries. Only from the experience of Silver Horse.
Similarities and differences between palletizing robot and handling robot
I am an application designer of a well-known robot manufacturer in China, and I am familiar with commonly used robots.
I think the two kinds of robots are the same in terms of hardware composition and control mode, specifically, the hardware structure is composed of driver, motor, reducer, control system and so on. Of course, in the number of axes, the palletizing robot is generally four axes. The conventional handling robot is six axes, but the structure of each axis is the same.
The difference is that the palletizing robot belongs to an independent series of industrial robots, and its application is relatively specific. Generally, it can only carry on the plane, and can not rotate in space like the six axes. This form of movement is determined by the number of axes. However, palletizing applications are generally added to the software in palletizing applications, and the palletizing program can be generated automatically through the necessary settings of the application setup wizard.
