Description

MASK PACKAGING MACHINES

The present invention relates to a mask packaging apparatus, and more particularly, to a mask packaging apparatus capable of automatically and quickly performing the operation of inserting a mask into a packaging material whose one end has been opened.

Masks are used to cover the nose and mouth to prevent inhalation and scattering of germs or dust. In particular, the mask is popularly used for the purpose of preventing respiratory diseases by preventing the inflow of fine foreign substances including dust from the outside into the body through the mouth and nose.

Recently, as the number of patients with respiratory diseases increases due to an increase in fine dust, etc., and various viral diseases are frequently prevalent, the demand for masks is also rapidly increasing.

In general, the mask is manufactured in the form of a mask body in the form of a sheet made of a fibrous material such as gauze or non-woven fabric in a hemispherical or square shape, and a band is attached to both sides of the mask body to wrap around the nose, mouth and chin. In the automatic mask production system, the mask is packaged by a packaging material in the form of a pouch that is opened at one end.

In the prior art, a mask packaging apparatus capable of automatically performing a mask packaging operation has been proposed. A conventional mask packaging apparatus includes a turntable rotating at a predetermined step, a plurality of grippers configured to grip both ends of an inlet of a packaging material and provided in plurality on a circumference of the turntable, and disposed on one side of the turntable to supply a packaging material to the grippers a packaging material supply unit that lifts the packaging material supplied from the packaging material supply unit one by one and delivers them one by one to each of the grippers rotated by the turntable; It includes an inlet expansion unit, a mask input unit for inserting masks one by one into the opening of the packaging material that is opened by the entrance expansion unit, and a mask supply unit for sequentially supplying a plurality of masks to the mask input unit.

However, the conventional mask packaging apparatus has disadvantages in that the structure is complicated, the number of parts is excessively large, and the overall size of the apparatus is excessively large. In addition, the conventional mask packaging apparatus has a disadvantage in that the overall process time is long because operations such as supply of packaging material, opening of the mouth, and input of the mask are sequentially performed one by one. In addition, since the conventional mask packaging apparatus puts the mask into the packaging material without reducing the size, the packaging material size compared to the mask size must be unnecessarily large, which has a disadvantage in lowering economic efficiency.

In addition, in succession to the clamp unit 180 holding the rear end of the packaging material 20, the packaging material 20 is moved forward in a state in which the suction of the packaging material chuck 160 is released. The front end is brought as close to the front end of the packaging material chuck 160 as possible. The clamp unit 160 moves the clamp 181 to a position capable of gripping the rear end of the packaging material 20 by the primary driving of the driving cylinder 182 , and then the packaging material of the packaging material chuck 160 . Release the vacuum adsorption to ( 20 ), and in a state in which the clamp 181 holds the rear end of the packaging material 20 , the driving cylinder 182 operates to further advance the packaging material 20 by the secondary driving do. Sequential driving of the driving cylinder 182 and the clamp 181 and driving for vacuum adsorption and vacuum adsorption release of the packaging material chuck 160 are controlled by a control unit (not shown). The control unit also controls the rotational driving of the outer cylinder 130 as described above.

When the outer cylinder 130 continues to rotate and the corresponding mask chuck 150 and the corresponding packaging material chuck 160 reach a section of approximately 135 degrees, as shown in FIGS. 6 and 7 , the corresponding mask chuck 150 is The first cam mechanism 2A (refer to FIG. 1) moves closer to the entrance of the width reduction hole 141, and the second cam mechanism 2B; While getting closer to the outlet of the reduction groove 141, the upper adsorption unit 191 of the inlet expansion unit 190 rises in a state in which the upper ply of the packing material 20 is adsorbed, and the front end inlet of the packing material 20 wide enough At this time, it should be noted that when the mask chuck 160 descends, the front inlet of the packaging material 20 may be further expanded. The control of the inlet expansion unit 190 is controlled by the aforementioned control unit. In addition, as described above, the inlet expansion unit 190 may include a lower adsorption unit and a lower elevating cylinder to further expand the front inlet of the packaging material 20 .

When the outer cylinder 130 continues to rotate and the corresponding mask chuck 150, the corresponding packaging material chuck 160, and the corresponding width reducing part 140 reach the mask insertion section of approximately 180 degrees, it is shown in Figs. As shown, the mask chuck 150 is advanced to the maximum by the first cam mechanism 2A (refer to FIG. 1), so that the front end of the mask 10 enters the inlet of the width reduction hole 141, and the The packaging material chuck 160 is advanced to the maximum by the second cam mechanism 2B (refer to FIG. 1 ), so that the front end of the packaging material 20 with its inlet wide open comes close to the exit of the width reducing hole 141 .

Subsequently, the vacuum adsorption state of the mask chuck 150 with respect to the mask 10 is released, for example, a push actuator 170 that may have a pneumatic cylinder structure moves the mask 10 placed on the mask chuck 150 forward. by pushing the mask 10 to pass through the width reduction hole 141 and then to be inserted into the packaging material 20 . At this time, since the entrance width of the width reduction hole 141 is greater than the width of the mask 10 and the exit width of the width reduction hole 141 is smaller than the width of the mask 10 , the mask 10 is bent or folded to increase the width. It may be inserted into the packaging material 20 in a reduced state. The driving of the push actuator 170 and the driving for vacuum adsorption and vacuum adsorption of the mask chuck 150 are controlled by the above-described control unit.

After that, the packaging material into which the mask is inserted is rotated together by the rotation of the outer cylinder and unloaded by a separate unloading device. .

By continuously repeating the above process, the mask can be automatically and quickly packaged in the packaging material.

While the present invention has so far been shown and described in connection with preferred embodiments for illustrating the principles of the invention, the invention is not limited to the construction and operation as so shown and described, and is not intended to be limited by the scope of the appended claims. It will be understood by those skilled in the art that many changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention.
