After the sole storage bin is improved by the intelligent shoemaking production line, the efficiency is improved and the cost is reduced. Take the sole matching workstation for the intelligent placement of the outsoles (sole) of the lieutenant's uniform leather shoes as an example: after calculating the size and code type of the soles of the lieutenant's uniform leather shoes, the optimal size for the reasonable placement of the soles is calculated as follows: the outer diameter of the sole storage bin disc is 1000mm, the inner diameter is 500mm, and each layer is evenly distributed with 20 soles; or the optimal size for the reasonable placement of the soles is the outer diameter of the sole storage bin disc is 1100mm, the inner diameter is 600mm, and each layer is evenly distributed with 22 soles; or the optimal size for the reasonable placement of the soles is the outer diameter of the sole storage bin disc is 1200mm, the inner diameter is 700mm, and each layer is evenly distributed with 24 soles. The maximum height of the heel of the outsole (sole) of the lieutenant's uniform leather shoes is 35mm. The height of the sole storage bin is set to 50mm. Considering the soles of hemmed shoes and soles with higher heel heights, the height can be set to 60mm. When the height is 50mm, there are 30 layers, which can store 600 soles (300 pairs); when the height is 60mm, there are 24 layers, which can store 480 soles (240 pairs). The shift output of the cold-glued shoe intelligent production line is 960 pairs. The soles are replenished manually during the breaks in the morning and afternoon to ensure the continuous output of shoes on the assembly line. According to calculations, the intelligent sole matching workstation can match a sole conservatively in 12 seconds. 8 hours (28,800 seconds) minus 20 minutes of rest time (1,200 seconds), the actual working time of the intelligent sole matching workstation is 27,600 seconds, and it can match 2,300 soles (1,150 pairs). The required capacity of 960 pairs is 69.57% of the actual capacity of 1,150 pairs, and the capacity margin of the intelligent sole matching workstation is 190 pairs (30.43%). The total power of the intelligent sole matching workstation is 1,800W, the actual power consumption is 0.5KWh / h, and the daily power consumption is converted to RMB 3.2. The installation of a sole consumes 5L of compressed air, and the daily consumption of compressed air is about 10m3, which is converted to RMB 3. The unit cost is 60,000 yuan, the sales unit price is 90,000 yuan, the daily depreciation fee is 30 yuan, the annual maintenance fee is about 3,000 yuan, and the average monthly fee is 1,155 yuan.
