Packaging machine and packaging method

Abstract

A packaging machine includes a first supplying unit, a second supplying unit, a placing mechanism, a moving mechanism, a guide member, and a joining mechanism. The first supplying unit supplies a first packaging material. The second supplying unit supplies a second packaging material. The placing mechanism places an object to be packaged on the first packaging material supplied by the first supplying unit. The moving mechanism moves the first packaging material, with the object to be packaged placed on the first packaging material, in a direction along a first axis. The guide member guides the second packaging material onto the object to be packaged. The joining mechanism joins the first packaging material and the second packaging material together. The object to be packaged is packaged using the first packaging material and the second packaging material.

What is claimed is: 
     
         1 . A packaging machine, comprising:
 a first supplying unit that supplies a first packaging material;   a second supplying unit that supplies a second packaging material;   a placing mechanism that places an object to be packaged on the first packaging material supplied by the first supplying unit;   a moving mechanism that moves the first packaging material, with the object to be packaged placed on the first packaging material, in a direction along a first axis;   a guide member that guides the second packaging material onto the object to be packaged; and   a joining mechanism that joins the first packaging material and the second packaging material together, wherein   the object to be packaged is packaged using the first packaging material and the second packaging material.   
     
     
         2 . The packaging machine according to  claim 1 , wherein
 the joining mechanism includes
 a first joining portion that joins the first packaging material and the second packaging material together at a position on one side with respect to the object to be packaged on a second axis intersecting with the first axis, and 
 a second joining portion that joins the first packaging material and the second packaging material together at a position on other side with respect to the object to be packaged on the second axis. 
   
     
     
         3 . The packaging machine according to  claim 1 , wherein
 the joining mechanism includes
 a third joining portion that joins the first packaging material and the second packaging material together at a position on one side with respect to the object to be packaged on the first axis, and 
 a fourth joining portion that joins the first packaging material and the second packaging material together at a position on other side with respect to the object to be packaged on the first axis. 
   
     
     
         4 . The packaging machine according to  claim 1 , wherein the second supplying unit is configured to supply the second packaging material different from the first packaging material. 
     
     
         5 . The packaging machine according to  claim 1 , wherein
 the first packaging material is formed in a shape of a roll, and the first supplying unit is configured to supply the first packaging material by unreeling the first packaging material from the roll, and   the second packaging material is formed in a shape of another roll, and the second supplying unit is configured to supply the second packaging material by unreeling the second packaging material from the another roll.   
     
     
         6 . A packaging method of packaging an object to be packaged using a packaging machine into which a first packaging material and a second packaging material are configured to be loaded, comprising:
 placing the object to be packaged on the first packaging material;   conveying the first packaging material, with the object to be packaged placed on the first packaging material;   guiding the second packaging material onto the object to be packaged; and   packaging the object to be packaged by joining the first packaging material and the second packaging material together.   
     
     
         7 . The packaging method according to  claim 6 , wherein the first packaging material and the second packaging material are joined together after the first packaging material and the second packaging material are cut. 
     
     
         8 . The packaging method according to  claim 6 , wherein the second packaging material is different from the first packaging material. 
     
     
         9 . The packaging method according to  claim 8 , wherein
 the first packaging material has a first cushioning layer made of a first cushioning medium, and   the second packaging material has a second cushioning layer made of a second cushioning medium different from the first cushioning medium.
