In the packing table of the present invention, the display section may be a first opening extending parallel to each rotation axis of the first support roller and the second support roller and formed on the top surface of the top plate. In this case, when cutting the packaging film stretched between the first support roller and the second support roller with scissors, the operator inserts the movable blade of the scissors into the first opening, and 1. You can cut the packaging film along the opening.

In the packaging table of the present invention, the packaging film placed on the pair of first support rollers is pulled out, and the packaging film is wound around the article placed on the pair of second support rollers. In this state, the distance between the packaging film stretched between the first support roller and the second support roller and the display section may be large enough to allow either a static blade or a moving blade of scissors to enter. . In this case, the packaging stand allows one of the movable blade and the static blade of the scissors to fit into the space between the packaging film and the display section, making it easy to cut the packaging film with the scissors.

In the packaging stand of the present invention, the diameter of the first support roller may be smaller than the diameter of the second support roller. In this case, in this packaging stand, by making the first support roller smaller, the height at which the packaging film is placed on the first support roller can be lowered, making it easier to place the packaging film. It is possible to provide a packaging table that places less burden on the worker.

The packaging table of the present invention may include a rotation suppressing portion that suppresses rotation of the first support roller. In this case, in this packaging stand, the rotation of the first support roller is suppressed by the rotation suppressing part when wrapping the packaging film around the object to be packed. By suppressing the rotation of the first support roller, the packaging film stretched between the first support roller and the second support roller can maintain a constant tension without bending while the object to be packed is rotating. The packaging film can be tightly wrapped around the packaged item.

The lower frame body 24 is a framework that constitutes the lower part of the packaging table main body 25. The lower frame body 24 is connected to the lower part of each support column 22 and reinforces the packaging stand main body 25.

The first support roller unit 38 has a first support roller stand 45, a pair of first support rollers 40, and a rotation suppressing section 60, as shown in FIGS. 1 to 3. The first support roller unit 38 is arranged at the rear end of the top plate 20. The first support roller unit 38 is arranged behind the first opening 80. The rotation shaft 42 of each first support roller 40 extends parallel to the rear edge of the top plate 20.

The first support roller 40 has a cylindrical rotating shaft 42 and a rotating part 43 that is concentric with the rotating shaft 42 . There is a pair of first support rollers 40, and the rotation axes 42 of the pair of first support rollers 40 are parallel to each other. Further, the pair of first support rollers 40 are spaced apart from each other. Furthermore, a packaging film 50 wound into a roll is placed on the pair of first support rollers 40 . The material of the packaging film 50 is transparent polyethylene with a thickness of 40 μm.

The first support roller stand 45 includes a support stand 44 and a pair of first L-shaped plates 46 . The support stand 44 has a plate shape and is fixed to the top plate 20 at its rear end. The first L-shaped plate 46 has an L-shaped plate shape. The first L-shaped board 46 has a vertical board 48 and a horizontal board 49. The lower edge of the vertical plate 48 and one of the left and right edges of the horizontal plate 49 are continuous. The vertical plate 48 and the horizontal plate 49 are perpendicular to each other. The standing plate 48 has a rectangular plate shape with a depression in the center of the upper edge when viewed from the side. The horizontal plate 49 has a rectangular plate shape and is joined to the support base 44 . The vertical plate 48 has two shaft holes 47 formed at the same height. The horizontal plate 49 is joined onto the support base 44 with bolts. The upright plates 48 are arranged to extend vertically upward from the left and right end positions of the support base 44, respectively.

The rotation suppressing section 60 includes a base 61, a push rod 62, a handle 63, a push plate 64, and an elastic sponge 65. The base 61 has a plate shape and extends vertically upward from the rear end of the support base 44 . The base 61 has a screw hole formed in the upper part of the center portion in the left-right direction. The screw hole passes through the base 61. The extrusion rod 62 has a cylindrical shape, and its outer peripheral surface is threaded so as to be screwed into a screw hole in the base 61. The handle 63 is attached to the rear end of the push rod 62. As the handle 63 rotates, the push rod 62 can be moved back and forth.

The extrusion plate 64 has a plate shape and is arranged in front of the base 61 and parallel to the base 61. Further, the push-out plate 64 is connected to the front end of the push-out rod 62, and moves in the front-back direction without rotating as the push-out rod 62 moves in the front-back direction. The elastic sponge 65 is attached to the entire front surface of the extrusion plate 64. The rotation suppressing section 60 rotates the handle 63 to move the extrusion plate 64 and the elastic sponge 65 until they come into contact with the rear end of the rotating section 43 of the first support roller 41 on the rear side. The rotational speed of the first support roller 41 on the rear side is suppressed by the resistance force generated by the contact between the rotating part 43 and the elastic sponge 65. The rotation speed of the rear first support roller 41 can be adjusted depending on the degree of contact with the elastic sponge 65.

The second support roller unit 39 includes a pair of second support rollers 30 and a pair of second L-shaped plates 35 . The second support roller unit 39 is arranged at the front end of the top plate 20. The second support roller unit 39 is arranged ahead of the first opening 80. The rotation shaft 32 of each second support roller 30 extends parallel to the front edge of the top plate 20.

The second support roller 30 has a cylindrical rotating shaft 32 and a rotating part 33 that is concentric with the rotating shaft 32 . The diameter γ of the first support roller 40 is smaller than the diameter β of the second support roller 30. Therefore, the first support roller 40 is not installed excessively above the second support roller 30.

The second L-shaped plate 35 has an L-shaped plate shape. The second L-shaped board 35 has a vertical board 36 and a horizontal board 37. The lower edge of the vertical plate 36 and one of the left and right edges of the horizontal plate 37 are continuous. The vertical plate 36 and the horizontal plate 37 are perpendicular to each other. The standing board 36 has a rectangular plate shape when viewed from the side. The horizontal plate 37 has a rectangular plate shape that is joined to the upper frame body 21 . The vertical plate 36 has two shaft holes 34 formed at the same height. The horizontal plate 37 is joined under the upper frame body 21 with bolts. The second support rollers 30 are rotatably supported by inserting the right and left ends of the rotation shafts 32 of the pair of second support rollers into the shaft holes 34 of the standing plate 36.

The first support roller 40 is located at a higher position than the second support roller 30. Therefore, when the packaging table 10 cuts the packaging film 50, the movable blade of the scissors 150 is inserted into the first opening 80 and the packaging film 50 stretched between the first support roller 40 and the second support roller 30. There is an interval where 121 can be inserted and cut. This makes it easier for the packaging table 10 to cut the packaging film 50 with the scissors 150.

The scissors 150 includes a moving blade part 120, a static blade part 130, and a threaded part 140, and the moving blade part 120 and the static blade part 130 are pivotably supported by the threaded part 140 so as to be rotatable (openable and closable). It is the composition. The moving blade section 120 includes a moving blade 121 and a moving blade side handle 122. The stationary blade section 130 includes a stationary blade 131 and a stationary blade side handle 132.

The operation when packing work is performed on the packing table 10 will be explained. As shown in FIGS. 4 and 5, first, the operator pulls out the cylindrical packaging film 50 placed on the pair of first support rollers 40 to the position of the pair of second support rollers 30. Since the first support roller 40 is located at a higher position than the second support roller 30, the packaging film 50 stretched between the first support roller 40 and the second support roller 30 has a constant inclination angle α. .

Next, the operator places the cylindrical object to be packed 110 on the pair of second support rollers 30 . The operator rolls the cylindrical object to be packed 110 in the packing space A and places it on the pair of second support rollers 30 from above the second opening 81 . At this time, the object to be packed 110 becomes rotatable around the central axis on the second support roller 30. When the object to be packed 110 is placed on the pair of second support rollers 30, the packaging film 50 is sandwiched between the pair of second support rollers 30 and the object to be packed 110. At this time, a certain tension is generated in the packaging film 50 stretched between the first support roller 40 and the second support roller 30.

The packaging table 10 is designed so that the inclination angle α between the packaging film 50 stretched between the first support roller 40 and the second support roller 30 and the top plate 20 is between 9° and 14°. If the inclination angle α is small, it is not possible to secure a space for the movable blade 121 of the scissors 150 to enter, and if the inclination angle α is large, the scissors 150 must be tilted greatly to match the inclination angle to cut, which is inconvenient. .

Next, the operator rotates the object to be packed 110 around the central axis on the pair of second support rollers 30 and wraps the packaging film 50 around the object to be packed 110 . A certain tension is also generated when wrapping the packaging film 50. This makes it easy to wrap the packaging film 50 around the packaging table 10.

In the packaging table 10, when the packaging film 50 is wound, the second support roller 30 and the first support roller 40 on which the roll-shaped packaging film 50 is placed rotate. If the pulling speed of the packaging film 50 placed on the first support roller 40 is faster than the winding speed of the packaging film 50 on the second support roller 30, there will be a gap between the first support roller 40 and the second support roller 30. The stretched packaging film 50 loses tension and bends. On the other hand, the packaging table 10 is configured such that the rotation suppressing section 60 suppresses the rotation of the first support roller 40 on the rear side. Thereby, the packaging table 10 prevents the unwinding speed of the packaging film 50 from becoming faster than the winding speed of the packaging film 50. Therefore, when wrapping the packaging film 50, the packaging film 50 is wrapped around the object to be packed 110 without bending.

Next, the operator cuts the packaging film 50 wrapped around the object to be packaged 110 using the first opening 80 formed in the top plate 20. As shown in FIGS. 3 to 5, the first opening 80 has a slit shape. The operator can insert the movable blade 121 of the scissors 150 into the first opening 80 from the right and cut the packaging film 50 toward the left while aligning the first opening 80. As described above, the packaging film 50 stretched between the first support roller 40 and the second support roller 30 has a constant tension even during cutting, so it can be easily cut.

The packaging table 10 has a first opening 80 . The operator cuts the stretched packaging film 50 while aligning the movable blade 121 along the first opening 80. Thereby, the operator can cut the packaging film 50 straight with the scissors 150. Since the first opening 80 is formed within the reach of the operator, it can be easily cut.

Next, the operator attaches and fixes the end of the packaging film 50 wrapped around the object to be packaged 110 with a horizontally long strip-shaped fixing tape (not shown). Next, the operator stores the packaging film 50 protruding from the left and right side surfaces of the cylindrical object to be packed 110 into the hollow portion 111 of the object to be packed 110. Next, the operator attaches a round fixing tape (not shown) to the hollow portion 111 to fix the packaging film 50. Next, the operator moves the packaged object 110 to the inspection space B. In the inspection space B, the worker pulls out the product label mount 100 from the upper horizontal part 70B of the product label hanger 70, affixes the product label 101 to the fixed packaging film 50, and completes the packaging work.

In the packaging table 10 of Example 1, the top plate 20 and the rotating shaft 42 are parallel to each other and are spaced apart from each other, and the packaging film 50 wound into a roll is placed rotatably around the central axis. A pair of first support rollers 40 and a rotating shaft 32 are parallel to each other, are located below the first support roller 40, and have a gap between them, and the object to be packaged 110 is rotatably placed thereon and rotated. A second support roller 30 whose shaft 32 is parallel to the rotation axis 32 of the first support roller 40 is provided. In this packaging table 10, a certain tension is generated in the packaging film 50 stretched between the first support roller 40 and the second support roller 30. Therefore, the worker can easily package the object to be packed 110.

The packing table 10 of the first embodiment has a first opening that extends parallel to each rotation axis of the first support roller 40 and the second support roller 30, and is provided between the first support roller 40 and the second support roller 30. 80. This packaging table 10 can be cut while aligning the movable blade 121 of the scissors 150 along the first opening 80. Therefore, the operator can cut the packaging film 50 straight with the scissors 150.

In the packaging table 10 of Example 1, the packaging film 50 placed on the pair of first support rollers 40 is pulled out and wrapped around the object to be packed 110 placed on the pair of second support rollers 30. In this case, the distance between the packaging film 50 stretched between the first support roller 40 and the second support roller 30 and the display section is large enough to allow the movable blade 121 of the scissors 150 to fit therein. This packaging stand 10 facilitates cutting of the packaging film 50 with scissors 150.

In the packaging table 10 of Example 1, the diameter γ of the first support roller 40 is smaller than the diameter β of the second support roller 30. Therefore, since the first support roller 40 is not installed excessively above the second support roller 30, the packaging film 50 wound into a roll can be easily placed on the first support roller.

The packaging table 10 of the first embodiment includes a rotation suppressing section 60 that suppresses rotation of the first support roller 40. The packaging film 50 is wrapped around the object to be packaged 110 without bending.
