Description

A hopper with picking function

Technical field

The invention relates to a feeding device for small objects, in particular to a hopper with a picking function, belonging to the technical field of loading equipment.

Background technique

The traditional brush for calligraphy, the brush for painting, and the foundation for women's makeup are all short cylindrical. For example, the brush is usually used as the raw material for the hair of the wolf, the sheep and the chest of the poultry. After sorting, a plurality of vellus hair bundles are bundled at the root and glued together, the root is implanted at one end of the sheath sleeve, and the other end of the sheath sleeve is inserted at the end of the sheath.

Although modern industry is very developed, for traditional stationery such as writing brushes, because of its unique personality and style, it is still mainly produced by experienced personnel in hand workshops, and has not entered industrial manufacturing. After receiving the order, assemble the corresponding pen and pen, and print the text or label according to the customer's needs. In recent years, with the growth of the brush market, pure hand-made has shown drawbacks, mainly because of low work efficiency, high labor intensity, and the salary of skilled workers is increasing year by year. Once the delivery time conflicts with the busyness of the farm, festivals, etc., It is difficult to deliver on time.

When the pen tip is assembled with the pen holder, it needs to be dispensed in the pen tip sleeve, and the pen holder needs to be printed, and the worker's long-term contact with the glue and the ink is easy to damage health. Therefore, the assembly of the pen tip and the pen holder is industrialized by using equipment, which not only maintains the traditional style of the product, but also improves the work efficiency, reduces the labor intensity of the worker, and ensures the consistency of the finished product.

Since the pen holder is long, it can be placed in the body of the pen hopper by the operator in advance; the one end of the pen head is a bristles and the other end is a sleeve, and the overall size is relatively short, which is inconvenient for the operator to pre-finish. The tip of the pen is dumped in the body of the large pen hopper, which is bound to be disordered. The premise of industrial assembly is to take out a lot of messy and disorderly pens one by one from the hopper body, and transport them in a uniform direction on the production line. A short cylindrical material similar in shape to the tip of the pen encounters the same problem during the loading process.

Summary of the invention
