Description

Technology Field

[0001] The present invention relates to a cushion product switching and transfer device for a cosmetic packaging machine, and more specifically, to a cushion product switching and transfer device for a cosmetic packaging machine that can automatically switch and package a cushion being transferred on a conveyor. Background Technology

[0002] Generally, cosmetic puffs (cushions) are mainly used when applying powder after applying liquid foundation, skin cover, or twin cake after applying basic skincare products (skin lotion, essence, and nourishing cream) to the skin of the human body, such as the face, or when applying twin cake immediately after applying the basic skincare products.

[0003] There are many different types of cosmetic puffs depending on the material and shape. These include velvet-type puffs made of cotton, polyester, nylon, acrylic, or acetate with piles on the surface, and sponge-type puffs made of NBR (Nitrile Butadiene Rubber) latex sponge, rubycell (a PU puff that is dense and has a texture similar to natural latex, unlike conventional general PU puffs), flocking (Polyurethane Flocked Foam) sponge, SBR (Styrene Butadiene Rubber), NR (Natural Rubber), etc.

[0004] First, velvet-type puffs form lint, leaving makeup residue behind after use, which poses hygiene issues. Furthermore, for users with skin allergies or atopic tendencies, using them can cause skin problems such as skin irritation; consequently, sponge-type puffs containing natural latex are currently being used.

[0005] Here, the above sponge-type puff is primarily used for twin cakes or liquid foundations. When the material is the above NBR (Nitrile Butadiene Rubber) latex sponge or Rubycell, it is suitable for oily makeup due to its strong oil resistance. It also exhibits strong abrasion and water resistance, preventing volume changes and cell cracking during washing or long-term use, and possesses excellent elastic recovery. It is recommended for twin cakes, skin covers, liquid foundations, and cleansing.

[0006] Cosmetic puffs commonly used can be manufactured by foaming a sponge or soft urethane foam to a predetermined thickness and size, and then cutting it into a specific size and shape.

[0007] The puff manufactured in this way has cushioning and elasticity, allowing the user to easily and evenly apply cosmetics to the skin. Additionally, to provide a better tactile sensation when the puff contacts the skin, a Rubycell fabric with a soft texture may be bonded to the working surface of the puff.

[0008] Meanwhile, conventional cosmetic puffs (cushions) are manufactured using an automated process in which raw materials are punched into a circular shape using a punching device and transported via a conveyor. However, conventionally, there is a problem in that it is difficult to improve productivity because workers manually feed the circular cushions, which are automatically transported via a conveyor, into the packing material.
