To achieve success in the current packaging market, external appearance of commodities arranged on the shelves shall be exquisite to render consumers unforgettable experience upon purchase. To this end, successful packaging design will maintain stable sales volume and promote sales growth of products. Hence packaging of products can be regarded as a silent promoter.
Under the condition of the same product quality, the market competition is the competition in packaging. Therefore, cartoning of regular bulbs is born. After being boxed, regular bulbs are not only with pleasant looking, but also convenient for exhibition, and thus they are more welcomed by the retailers. Additionally, boxed regular bulbs provide more convenience and added value, as they are not so easily subject to pressure during transportation and carry.
In recent years, bulb cartons are the main-stream packing means. However, it is not easy work to stuff bulbs into cartons. Currently, bulb cartoning is mainly done manually, i.e. bulbs are stuffed into formed cartons and then closed. However, such way of cartoning has low efficiency, and does not suitable for modern large-scale production; in addition, bulb cartons are liable to crack, resulting in loss and damage to the reputation of the enterprises.
For design and manufacture of a bulb unloading mechanism for the fully automatic bulb Cartoner , it requires solving the technological problem of arranging the bulbs in a row and making each bulb fall fast and accurately into the cabin of the Cartoner, so as to replace the current manual cartoning with fully automatic mechanical cartoning. Provision of the bulb unloading mechanism that features economical and simple structure, reliable movement, high efficiency, precise bulb unloading and free adjustability may make the automatic bulb cartoner more economical and applicable.
(1) Installation on the holder for the column of the bulb Cartoner; (2) adjustable side support plate installed on the holder; (3) two guide rails on the inside surface of the side support plate, barrier fixing block and motor on the outside surface; the said guide rails and batten are inclined against the horizontal surface to some degree; (4) the bulb barrier of the movable hinge on the barrier fixing block; the said bulb barrier is located at the bulb unloading port of the two guide rails; (5) the crank-link mechanism driving the bulb barrier to sway through a high-speed stepper motor.
(2) Working principle. The working principle of the bulb unloading mechanism is that when a bulb formed is sent to the bulb unloading mechanism via the conveying belt, the lamp holder will first fall to the bulb holding groove, while the two guide rails carry the bulb body; as the two guide rails and the batten are inclined, the bulb will gradually move along the two guide rails to the bulb unloading port due to gravity and pressure of the following bulbs, and then stop temporarily at the bulb unloading port due to impact of the bulb barrier. The high-speed stepper motor linked with the bulb conveying belt assembly will work simultaneously based on a certain angle of the Cartoner encoder with the moving cabin of the Cartoner; during operation, the bulbs will be driven to sway by the crank-link mechanism to open or close the bulb unloading port at the certain angle of the encoder; one after another bulb is laid down and falls into the cabin conveyed by the conveying device of the bulb Cartoner.
Assembly of the bulb unloading mechanism is economical and simple with reliable movement, high efficiency, precise bulb unloading and free adjustability to ensure product quality.
Conclusion
Through production and use by Shanghai Lighting and other units, the bulb unloading mechanism performs well in our application of Cartoner. Due to its economical efficiency, simplicity, reliable movement, high efficiency, precise bulb unloading and free adjustability, the bulb unloading mechanism can be applied with product quality ensured, having solved the problem of arranging bulbs in a row and making each bulb fast and accurately fall into the cartoning cabin. With greater economical efficiency and applicability, the bulb unloading mechanism may realize a cartoning speed of above 180 cartons/minute or up to 210 cartons /minute, and thus it may meet the requirements of modern large-scale production.
