| Abstract_FL | With the improvement of people's living standard in China, the demand for flowers has been increasing annually, and further the sleeving requirement of potted flowers is also rising. The sleeving requirement is indicated to sleeve transparent packing bags for potted flowers. Packing bags are designed to beautify and protect potted flowers during transportation. In order to improve productivity, many large-scale enterprises producing potted flowers in Europe are using sleeving machine to sleeve potted flowers. But there are some problems due to the differences of bag type and producing process when foreign sleeving machine is used in China, along with the high price of foreign machines being 5-10 million Yuan. Now the automated production technology of greenhouse horticultural production in Netherland has reached the leading position in the world. The Netherlands has been developing automated sleeving machine for potted flowers. However, the sleeving machines have a problem, i.e., their opening bag mechanisms occasionally unsuccessfully make bag opening, because there is not a unit to keep bag from falling. According to the requirements of the domestic market and the instability problems of opening bag for small-size sleeving machines whose productivity are 1 200 pots/h, it is proposed to develop a hooking bag unit based on the above opening bag mechanism. The hooking bag unit can prevent the bag falling from the suckers during opening period, which will improve sleeving success ratio. The hooking bag unit is mainly constituted with push cylinder, hooking bag claw, link and synchronized shaft, etc. In this paper, based on the overall design of the opening bag mechanism, the main structural parameters of the sucker, moving unit to open bags and hooking bag unit were determined. First, according to the characteristics of packing bags, we chose the sucker type. Second, based on external diameter of the biggest pot and fixed hole spacing, the sucker spacing has been determined. Third, according to moving process of opening bag mechanism, moving unit to open bags has been designed. At last, based on performance characteristics of opening bag mechanism, hooking bag unit has been designed. Using the opening bag mechanisms without hooking bag unit and with hooking bag unit, opening bag performance experiments have been completed respectively to examine the opening bag characteristics. Results are as follows. In the experiment without hooking bag unit, to keep opening bag success ratio being greater than 90%, opening velocity of the sucker must be less than 0.3 m/s, and consumed time for opening bag was greater than 0.5 s. In the experiment with hooking bag unit, spacing between claw and sucker, and the widths of hooking bag claw were determined to be 2 and 4 mm, respectively. After an additional hooking bag unit being used, the opening velocity of sucker could be increased to 0.41 m/s, and consumed time for opening bag was just 0.37 s which could save 0.21 s compared with no hooking bag unit, meanwhile opening bag success ratio also could keep greater than 95%. For a sleeving machine whose opening bag mechanism had not a hooking bag unit, its productivity could achieve 1 200 pots/h, and consumed time for packing one pot (packing cycle time) was 3 s, so that according to above experiment results, when using the hooking bag unit, packing cycle time could be saved by 0.21 s with a success ratio of opening bag as high as 95%. It meant that the productivity of sleeving machine for potted flowers could enhance by 7.3%by using the hook bag unit. |
