Application of Central Conveying System

Share to:

One game machine manufacturer in Dongguan is mainly engaged in design, production and sales of electronic game machine, which mainly produces non-gambling recreational game machine including palm, console and mechanical models, and the electronic plastic toy exported to dozens of countries in Europe and America.  

During first phase of the conveying system, 17 sets of injection molding machines were planned in workshop A. There were three kinds of materials used in the system: the ABS and two kinds of PP materials, which were packaged in 25kg per bag. Shini Robot cut open the material bag for feeding. The customers only need to stack the materials in specified place in central material room. After system visually perceived the required material, Robot will carry the material to correct hopper for feeding. 

 

In this workshop, material dosage was 17kg/hr per unit. The total dosage amount of the first phase was 289kg/hr. There were 3 material hoppers in 500kg capacity that equipped in the room (include dosing amount for second phase). The ABS material requires the drying treatment, which was centrally processed by Dryer of the customer. We only needed to convey the material to the Dyer.  For customer’s requirement to make the three kinds of materials available in 17 sets of the IMM,   we set up a set of material distribution station in the room. The inlet of material distribution station was connected to the outlet of hopper and Dryer. The pipeline of each injection molding machine was extending to material distribution station, with quick connector mounted. Then the operator could easily switch the material in each machine via the quick connector. The workshop of the 17 sets of IMM was divided into 2 areas, and each area was equipped with a set of central vacuum generator SRB-80-V for central air supply. There’s an extra set of blower for backup, which was connected with two sets of blowers in series. When the blower breaks down, it could quickly switch to the backup blower, which ensures normal operation of the whole system.

 
The first phase of the system was completed at the end of 2014, which has been excellently operated by the customer. It largely reduces workshop input, well organized the workshop and has been well received by the customer. The second phase of system will be constructed in June of this year, and will be completed in middle of June. At present, we are discussing the issue about the third phase of central conveying system. We believe that we will have more of opportunities for cooperation.
