After the workers finish the packing of the products, it enters into the conveying line 1, the products are conveyed to the sealing machine, and then passes through the conveying line 2, in the line 2, there is a positioning device which can also be called as a positioning plate (it has been successfully applied in Wahaha's production line), this device and the positioning plate can complete the rotating and positioning of the box, which can make the box to be positioned by the left side, and then conveyed to the buffer zone 1, and the buffer zone has a pushing device, this device can convey the box to the free space properly, after pushing the filled pallet to the buffer zone 2. This device can be suitable for conveying the box to the free space, in will be filled with pallets to promote dynamic buffer zone 2. buffer zone above the code stomping robot, the robot through the robot suction cups will be 15 boxes (sachets can be yards 15, box and listen to packages can be yards 8-10) the whole lifting the vertical lift, in the horizontal operation, to avoid the safety channel, width and height of 2 meters, through the safe passage after the Vertical placement in the yard stomping area, the front of the positioning plate has been rotating the box, so the robot does not need to rotate, in the placement is completed, in accordance with the original path back to the yard stomping area after the completion of 10 layers of yard stomping, by the forklift will be forked away in the placement of the idle yard plate. The front buffer zone 2 code plate in the box was removed for the empty plate, by manual removal and then wait for the buffer zone 1 code plate delivery over to be placed in the buffer zone 1 can be.
The system is also equipped with an emergency stop button, can be manually, automatically stop; robot support frame within the scope of work is equipped with a grating safety system, in case of malfunction or abnormalities in the alarm signal light, the system stops in an emergency, in the manual state of the exclusion of the alarm before the system can continue to run; there is an automatic memory function, in the event of power outages or failures to continue to complete the work.
Conveyor line drawings are as follows:
Running efficiency calculations:
According to the sealing time provided by the customer 15 boxes / minute, if one by one to grab the box requires 4 seconds a running cycle, complete the lifting of the product, conveying, placing in accordance with the path to return to the lower part of the walking area, so can not be applied to the guide rail of the difference between the complementary movement, can only take a straight line journey. To use such a working speed is not possible to complete the line, and very unsafe, according to the way the box as a whole delivery, according to a box conveyor over the beginning of the calculation, a yard plate full of 60 seconds, in this 60 seconds (the other two can be 32 seconds -40 seconds, can be 8-10 yards), the completion of the booster, gripping lifting, conveying, placing and returning to the time is sufficient.
The above is the product conveyance mode of box packing, please refer to the effect picture for the specific process.
The production cycle of the big bag product is 15 seconds/bag, so it directly completes the single code stomping conveyor, and there is enough time, mainly because the load is not big, so it can improve the running rate.
In summary, the use of Shenyang Dingleng electromechanical palletizing robot makes the handling and palletizing work efficiency greatly improved. It saves a lot of manpower and reduces the cost of labor. The robot can recover the invested cost after one year of operation. The robot will run for at least ten years under normal maintenance. With the rise of high-volume fully automated palletizing production lines, this palletizing system will have a broader market prospects and development potential!

For random pallets, palletizing robots are the only choice. Nevertheless, robotic loading also faces more problems and will be more difficult if it is to be produced at higher speeds.
A robot palletizer that handles random loads requires special software through which the robot palletizer is connected to the rest of the production line, which is a huge step forward.
A robot used to build random pallets can be integrated into a factory's warehouse management system (WMS). Ideally, it would be the front end of the WMS, working in coordination with the warehouse software to produce mixed pallets.
Sophisticated software can also meet the need for immediately shelf-ready pallets. Generally, this means that some or all of the primary containers must have their labels facing outward once the product has been palletized. Robotic palletizing equipment is also an option for another demanding application: palletizing in refrigerated warehouses. Handling boxes in a refrigerated warehouse is one of the most difficult tasks in consumer goods packaging. Workers have to frequently alternate tasks to keep their bodies warm, which indirectly reduces productivity and raises labor costs.
Automated random access palletizers are not the right choice in freezing environments because most automated random access palletizers use compressed air tubes that freeze in cold storage. Palletizing robots are more compact than automated palletizers, which is especially important since space is at a premium in refrigerated warehouses. Nevertheless, there are some problems with the use of robots in refrigerated warehouses. Some suppliers are beginning to design special palletizing robots for refrigerated warehouses.
An important thing to consider when using a palletizing robot is how the robot grips a product. Vacuum grippers are the most common robotic end-of-arm tool (EOAT). They are relatively inexpensive, easy to maneuver, and can efficiently load most loads. But vacuum grippers can also run into problems in specific applications, such as substrates with porous surfaces, flexible packaging with liquid contents, or packaging with uneven surfaces, to name a few.
Other EOAT options include a flap gripper, which grips the sides of a bag or other packaging format; a fork gripper, which is inserted into the bottom of a package to lift it up; and a bag gripper, which is a hybrid of a flap and fork gripper, with a fork section that wraps around the bottom and sides of the package.
Other combinations of basic EOAT types are possible. A beverage packer was having trouble palletizing corrugated pallets filled with bottles and shrink-wrapped, with vacuum suction cups ripping the film off the pallets.
