In general, masks were mainly used for hygiene purposes to prevent deterioration of the atmospheric environment such as yellow dust or fine dust, and inhalation of dust or bacteria in the workplace.

However, due to the recent coronavirus pandemic, the demand for medical masks is exploding around the world.

In order to meet the demand for such a mask, mass production of the mask is required, and an automatic packaging device for automatically packaging the mask in a wrapping paper (pouch) is essential.

In the conventional automatic mask packaging apparatus described above, a mask supply conveyor and a wrapping paper supply conveyor are installed in parallel to transport and supply the mask and the wrapping paper in a line, and while the entrance of the wrapping paper is opened up and down by the absorption means, the mask is adsorbed by the absorption means. It was moved up and down and moved back and forth to be inserted and packaged inside the wrapping paper, and then sealed and packaged.

However, in the conventional automatic mask packaging apparatus described above, the operation of opening the mouth of the wrapping paper and the operation of inserting and packaging the mask into the wrapping paper are performed by the adsorption of the adsorption means and the lifting and lowering of the adsorption means, and the transfer of the mask and the wrapping paper. When the speed is high, the packaging operation is difficult, and it has no choice but to work while the transport speed is slowed down, so there is a problem in that the overall productivity is greatly reduced.

In order to solve the problem of the conventional automatic mask packaging device, Registered Patent No. 10-2189672 discloses that the packaging paper supply conveyor and the mask supply conveyor transport and supply the trays supplied with the packaging paper and the mask in a line, but the entrance of the packaging paper is moved in the longitudinal direction.

However, the above-described automatic mask packaging device has a problem in that, although the operation speed is high, the productivity is greatly improved, but the manufacturing cost is improved due to the complicated structure of the device, and a lot of packaging defects are generated due to malfunction.

That is, the device is very complicated because the packaging work is carried out while transporting and supplying the wrapping paper and the mask in a line, and the insertion hole and the pusher are transferred in a line to the wrapping paper and the mask by each transfer conveyor. This is very difficult, and the manufacturing cost increases, and there is a problem in that a lot of packaging defects are generated due to malfunction.

Moreover, although the insertion hole is formed to be inclined toward the front, the front of the insertion hole is caught well at the entrance of the wrapping paper and is not smoothly inserted into the entrance of the wrapping paper.

In addition, when the mask supplied to the tray is pushed by a push and inserted into the packaging paper, the mask is pushed while the push is slightly floating on the bottom surface of the tray, and the mask is sandwiched between the push and the tray bottom. There was a problem in that the mask could not be smoothly pushed, and when the mask was pushed by the push, the mask was released to the top rather than the front, resulting in a packaging defect in which the mask was not packaged inside the wrapping paper.

At this time, the cover 36 is formed to extend to cover the space between the adjacent tray 30 and the space away from each other, so that the mask transferred and supplied by the tray falls into the inside of the mechanical device through the space between the trays, causing the device to malfunction. It is designed to prevent accidents in advance.

The wrapping paper sealing means 60 is configured to seal the inlet 2a of the wrapping paper while continuously transporting the wrapping paper 2 having the mask 3 inserted therein.

As unexplained reference numerals, 5 denotes a main body and 6 denotes a support leg.

Next, we will look at the operation and operation of the present invention configured as described above.

First, the wrapping paper 2 supplied from the wrapping paper supply unit 11 is continuously transferred and supplied by the first transfer conveyor 15 of the wrapping paper transfer supply means 10 .

And the mask 3 supplied from the mask supply unit 21 is continuously transferred and supplied in a tray 30 installed on the second transfer conveyor 25 of the mask transfer supply means 20 .

At this time, the wrapping paper 2 and the mask 3 are continuously transferred and supplied in a line at the same interval and at the same speed.

In this way, while continuously transferring and supplying the wrapping paper 2 and the mask 3, the inlet 2a of the wrapping paper 2 is opened vertically by the wrapping paper opening opening means 40.

That is, the wrapping paper is transferred by the upper and lower timing belts 45 and 45' passing in close contact with the bottom surface 42 and the upper surface 42' of the upper and lower suction blocks 41 and 41'.

At this time, long grooves 41a and 41a' connected to the suction means are formed on the bottom surface 42 and the top surface 42' of the upper and lower suction blocks 41 and 41', and the upper and lower timings are formed. Suction holes 45a are formed in the belt along the longitudinal direction, so that the upper and lower surfaces of the wrapping paper inlet 2a are transferred while adsorbing by the suction force.

In particular, at the center of the bottom surface 42 and the upper surface 42' of the upper and lower suction blocks, and at the center of the upper and lower timing belts 45 and 45', the protruding jaws 42a and 42a' in the longitudinal direction. ) and the insertion grooves 45b and 45b' through which the protruding jaws are inserted and guided are formed to engage with each other, so that the upper and lower surfaces of the wrapping paper inlet 2a are transferred while reliably adsorbed by better suction force.

In this way, the wrapping paper 2, which is adsorbed and transferred up and down by the upper and lower timing belts 45 and 45', includes the upper and lower suction blocks 41 and 41' and the upper and lower timing belts 45 and 45'. ) moves obliquely opposite to each other so as to open from the inflow part to the outflow part of the wrapping paper.

In this way, the insertion part 35 of the front of the tray 30 transferred by the mask transfer supply means 20 to the inlet 2a of the wrapping paper while transporting the inlet 2a of the wrapping paper 2 spread up and down. will be inserted.

This is because the slide block 75 installed on the slide rod 73 of the transfer chains 71 and 71 in the second transfer conveyor 25 of the mask transfer and supply means is a front and rear guide portion 77a of the guide rail 77. The tray 30 is moved forward by the guidance of the guide pin 75a in the , so that the insertion part 35 in the front of the tray is inserted into the inlet 2a of the wrapping paper.

At this time, the insertion part 35 of the tray is formed in the form of a duct inclined so that the size of the top and bottom and left and right becomes narrower toward the front, and is smoothly inserted into the inlet 2a of the wrapping paper.

In particular, since guide protrusions 35a, 35b, 35c, and 35d are protruding from the tip of the insertion part 35 of the tray 30 up and down left and right, the guide protrusion is formed at the entrance ( 2a), the tip of the inserting part 35 is guided so that the tip does not get caught in the entrance of the wrapping paper, thereby guiding the insertion of the inserting part 35 more smoothly.

As such, when the insertion part 35 of the tray is inserted into the inlet 2a of the wrapping paper, the push 56 of the mask packaging means advances and inserts the mask 3 on the tray upper part into the wrapping paper by pushing operation. it will be done

This is because the slide block 76 installed on the slide rod 74 of the transfer chains 72 and 72 in the third transfer conveyor 55 of the mask packaging means 50 is the front and rear guide portion of the guide rail 78 . In step 78a, the pusher 56 is moved forward while advancing by the guidance of the guide pin 76a to push the mask 3 of the tray 30 to be inserted and packaged into the wrapping paper 2 .

At this time, the insertion part 35 at the front of the tray is inserted into the inlet 2a of the wrapping paper, so that the mask 3 of the tray is smoothly inserted into the wrapping paper to be packaged.

In particular, the protrusion 56a protruding from the center of the lower portion of the pusher 56 is inserted along the U-shaped recess 31 formed in the center on the inner bottom surface of the tray 30 and the pusher 56 moves while the mask 3 is moved. ), so that the mask is caught between the pusher and the tray as in the prior art, thereby preventing the occurrence of a malfunction that cannot be pushed forward.

That is, the mask 3 of the tray is smoothly inserted into the wrapping paper 2 to be packaged.

In addition, since the upper part of the tray 30 is covered by the cover 37, the pusher 56 prevents the mask 3 from being released to the outside instead of in the front while pushing the mask 3, so the mask 3 is wrapped in wrapping paper. (2) It will be securely inserted and packaged.

This is before the cover 37, which is vertically erected and installed to rotate elastically by the hinge shaft 38 and the torsion spring 39 on one side of the upper part of the tray 30, before performing the packaging operation by the mask packaging means. 3 while being guided by the guide bar 90 installed along the upper longitudinal direction of the transfer conveyor 55, it rotates elastically to cover the upper part of the tray 30 .

In addition, after the packaging operation by the mask packaging means, the cover 37 is moved away from the guide bar 90 so that it stands up to its original position by the elastic force of the torsion spring 39 .

And, even if a problem occurs that the mask 2 of the tray 30 is separated from the tray through a gap without a cover during the pushing operation of the push, the cover ( 36) is installed horizontally, so that an accident in which the mask 2 falls into the machine device through the space between the trays and damages the machine device is prevented in advance.

In this way, after the mask 3 is inserted into the wrapping paper 2 by the mask packaging means 50 and packaged, the inlet 2a of the wrapping paper is sealed by the wrapping paper sealing means 60 to complete the mask packaging operation. it will be done

Therefore, the present invention spreads the entrance (2a) of the wrapping paper while continuously transporting and supplying the wrapping paper 2 and the mask 3 in a line, and then inserting the mask into the wrapping paper to insert and package and seal the tray 30 ), the mask insertion part 35 is integrally formed in front of the tray 30 and inserted into the entrance of the wrapping paper 2 while being transported with the tray 30 to guide the insertion of the mask 3 into the wrapping paper, so the conventional tray and the insertion part are provided separately Therefore, it is to perform the packaging operation quickly and accurately with a simple structure compared to the operation of placing and packaging in a line while conveying by each transportation means.
