Description

  The present invention relates to an air cap volume reducing device having a convex portion containing air.

  The air cap sheet is one of packing materials used for transporting precision machines that are vulnerable to impacts and furniture that is easily damaged. Since the air cap sheet has convex portions enclosing air, the air cap sheet functions as a cushion to absorb the impact when the precision machine is wrapped.

  Since the air cap sheet is unnecessary after transportation, it is handled as garbage except for being reused. However, the air cap sheet is bulky even when folded, and thus requires a large accommodation area and accommodation volume.

  Therefore, the air cap sheet folded with the pressure of manpower or a machine is pressed and crushed so as to rupture the convex portion. However, even if pressure is applied, the convex portion only deforms and remains without rupturing, and it takes time to reduce the volume.

Regarding such volume reduction of an air cap sheet, a volume reduction molding apparatus described in Patent Document 1 is known. The volume-reduction molding apparatus described in Patent Document 1 includes a notch forming unit in which a plurality of rows of incising blades having a notch width narrower than the outer shape of a convex part including air in an air cap sheet are arranged, a feed roller unit, and a traveling direction. The pressure-biased roller portions provided with projecting pieces orthogonal to each other in parallel are sequentially arranged. In this volume reduction molding device, when a used air cap sheet is inserted from the inlet, the cutting blade of the notch forming part cuts into the convex part, and the subsequent pressure bias roller part pushes out the air contained in the convex part. Thus, it is possible to reliably take out air and reduce the volume.
JP 2004-148789 A

  However, the volume reduction molding apparatus described in Patent Document 1 is provided with a notch forming part and a pressure biasing roller part in order to extract air from the convex part of the air cap sheet. Therefore, since the apparatus scale becomes large, the place where this volume reduction molding apparatus is installed is also limited.

  Accordingly, an object of the present invention is to provide a volume reduction device that can reliably extract the air contained in the convex portion of the air cap sheet, is small in size, has a simple structure, and is low in production cost.

  The air cap sheet volume reducing device according to the present invention is an air cap sheet volume reducing device in which a convex portion containing air is arranged on the entire surface, and a brush-like member in which wires are implanted at intervals smaller than the size of the convex portion. A perforation roller portion provided on the outer peripheral surface, a travel guide portion disposed below the perforation roller portion and provided with a plurality of holes on the upper surface on which the air cap sheet travels, and the perforation roller portion rotating And the perforating roller portion is adjusted to a height at which the tip of the wire rod of the brush-like member at the lower position is inserted into a hole provided in the travel guide portion. It is characterized by.

  According to the air cap sheet volume reducing device of the present invention, the structure is simple because the travel guide portion, the perforation roller portion provided with the brush-like member on the outer peripheral surface, and the rotation drive portion are provided. Costs can also be low.

  The first invention of the present application is an air cap sheet volume reduction device in which a convex portion containing air is arranged on the entire surface, and a brush-like member in which wires are implanted at intervals smaller than the size of the convex portion is provided on the outer peripheral surface.

  A perforation roller portion having a brush-like member provided on the outer peripheral surface is rotated by the power of the rotation drive unit. By rotating the perforating roller portion, the tip of the brush-like member pierces the convex portion of the air cap sheet. The perforating roller portion is arranged so that the tip of the wire member of the brush-like member on the lower side is at a height to be inserted into the hole provided in the traveling guide portion. Penetrates. In the brush-like member, the wire rods are planted at an interval narrower than the size of the convex portion, and are provided on the outer peripheral surface. Therefore, the tips of the wire rods of the plurality of brush-like members pierce the convex portion. The air that is flowing out.

  The second invention of the present application is characterized in that the hole provided in the traveling guide portion is formed smaller than the size of the convex portion.

  Since the hole of the travel guide part is formed smaller than the convex part of the air cap sheet, when the tip of the brush-like member abuts on the convex part and is pressed by rotation, the peripheral part of the convex part extends. When the convex portion sinks into the hole, it is possible to prevent the convex portion from passing below the perforating roller portion without the tip of the brush member being pierced.

  The third invention of the present application is characterized by comprising an elastic member for urging the traveling guide portion in the vertical direction.

  Since the elastic member biases the traveling guide portion upward from the lower side of the air cap sheet, the pressing force to the perforating roller portion increases and the air cap sheet passes between the perforating roller portion and the traveling guide portion. It is easy to adjust the load at the time.

  A fourth invention of the present application is characterized in that a peeling portion for allowing the air cap sheet to pass downward is provided at a position where the air cap sheet passes the perforation roller portion.

  When passing through the perforation roller section with the tip of the wire rod of the brush-like member stuck, it is wound around the perforation roller section as it is. By providing the peeling part to be made, the perforation roller part and the air cap sheet can be easily separated.

  The fifth invention of the present application is characterized in that a control unit for controlling the rotation speed of the rotation drive unit is provided.

  By providing the control unit that controls the speed of the perforation roller unit in which the brush-like member rotates, the volume reduction operation of the air cap sheet can be performed at a speed according to the skill level.

  The sixth invention of the present application is characterized in that it includes a discharge roller portion that presses and discharges the air cap sheet discharged from the discharge guide portion by rotation synchronized with the rotation of the perforation roller portion.

  Since the discharge roller unit presses and discharges the air cap sheet discharged from the discharge guide unit by rotation synchronized with the punching roller unit, the air cap sheet can be discharged without being wound around the punching roller unit. Further, if there is a convex portion where the contained air cannot escape due to the pressing of the discharge roller portion, the air can be completely extracted from the convex portion.

FIG. 1 is a perspective view illustrating an air cap sheet volume reducing device according to an embodiment of the present invention. FIG. 2 is a partial vertical cross-sectional view for explaining a volume reducing device for an air cap sheet according to an embodiment of the present invention. FIG. 3 is a schematic horizontal sectional view for explaining the air cap sheet volume reducing device according to the embodiment of the present invention. FIG. 4 is a view for explaining a mesh portion of the travel guide portion of the air cap sheet volume reducing device according to the embodiment of the present invention.

  As shown in FIGS. 1 to 3, the volume reduction device 1 includes a base base 3, a travel guide portion 4, a perforation roller portion 5, a motor 6, a peeling portion 7, and a discharge roller portion 8. ing.

  The base 3 is formed in a rectangular shape with a base plate 3a formed in a U shape in plan view, provided on the lower surface of the base plate, and a main body frame 3b serving as a leg of the base base 3, and a main body frame 3b And a level adjuster 3c for adjusting the height of the base 3 so that it is easy to work on the lower part of the base.

  The air cap sheet 2 is conveyed on the upper surface of the base table 3. The width of the base plate 3a can be determined as appropriate according to the work place. However, by setting the travel guide portion 4 as large as possible, a volume reduction device that does not require a large installation area can be obtained. it can. The base plate 3a of the volume reduction device 1 of the present embodiment is formed in a size of 100 cm × 100 cm.

  The traveling guide portion 4 is provided at a position that becomes a traveling path for conveying the air cap sheet 2 of the base plate 3a. The travel guide portion 4 has an introduction guide portion 4a whose vertical cross section is formed in a substantially square shape, a net portion 4b located on the lower side of the perforating roller portion 5, and a vertical cross section formed in a substantially square shape. A discharge guide portion 4c is arranged so that a portion parallel to the base plate 3a is positioned below the discharge roller portion 8.

  The net 4b is a wire net whose outer shape is formed in a rectangular shape. By setting the mesh size of the mesh part 4b to 4 mm to 6 mm, the mesh part 4b can be made smaller than the size of the convex part 2a containing the air of the air cap sheet 2. Moreover, since the size of the mesh holes only needs to be smaller than the size of the convex portion 2a, punching metal which is one of the perforated plates may be used. Moreover, when the board | plate material with thickness is used for the driving | running | working guide part 4, it is good also as a hole made into the concave shape which does not penetrate.

  Here, the net 4b of the travel guide 4 will be described in detail with reference to FIG.

  In the air cap sheet 2, columnar convex portions 2a are arranged in a staggered manner on the entire surface. Since the mesh part 4b of the traveling guide part 4 is a wire mesh, the hole can be made smaller than the diameter R of the circle when the convex part 2a is viewed in plan. When punching metal is used, the diameter of the through hole provided in the punching metal may be smaller than the diameter R of the convex portion 2a.

  As shown in FIGS. 1 to 3, the travel guide portion 4 has an introduction guide portion 4 a on the side where the air cap sheet 2 is introduced pivotally supported on the base plate 3 a. The travel guide portion 4 includes a spring 4d that is one of elastic members that urge the discharge guide portion 4c on the side from which the air cap sheet 2 is discharged in the vertical direction. When a pressing force is applied to the traveling guide portion 4, the height of the spring 4d of the traveling guide portion 4 is lowered around the point where the introduction guide portion 4a is pivotally supported by the base plate 3a, and the pressing force is no longer applied. The travel guide portion 4 returns to the original height position by the biasing force of the spring 4d.

  The perforating roller unit 5 is provided with a wire brush 5b which is one of brush-like members on the outer peripheral surface of the roller body 5a. In the wire brush 5b, a wire material is implanted at an interval narrower than the size of the convex portion 2a of the air cap sheet 2.

  The wire, which is the wire material of the wire brush 5b, is a copper wire having a length of about 1.5 cm and a wire diameter of 0.3 mm. By providing a wire brush 5b planted at a hair transplantation pitch of about 2 mm on the outer peripheral surface of a cylindrical roller body 5a having a diameter of 8 cm, the interval can be made narrower than the size of the convex portion 2a of the air cap sheet 2. . Both ends of the punching roller unit 5 are rotatably supported by a punching roller support member 5d provided upright on the base plate 3a.

  The motor 6 is a rotation drive unit that rotates the perforation roller unit 5 and the discharge roller unit 8. The gear 5c connected to the rotation shaft of the punching roller unit 5 is coupled by a motor 6 and a belt 6a, and the rotation of the motor 6 is transmitted to the punching roller unit 5 by the belt 6a. The motor 6 is connected to a control unit (not shown) that adjusts the rotational speed. This control unit can adjust the rotation speed by, for example, inverter control. When adjusting the rotational speed of the motor 6 by inverter control of the control unit, the motor 6 employs an AC motor. The adjustment of the rotation speed of the motor 6 of the present embodiment is in the range of adjustment from 20 rpm to 160 rpm.

  The peeling portion 7 is provided at a position where the air cap sheet 2 passes the punching roller portion 5 so as to pass the air cap sheet 2 downward. Both ends of the peeling portion 7 are attached to a perforation roller support member 5 d that supports the perforation roller portion 5. The peel-off portion 7 is formed by bending an iron plate in a substantially letter-shaped cross section. And the protrusion part 7a is provided in the perforation roller part 5 side. The protruding portion 7 a is arranged so that the tip end portion is buried in the wire brush 5 b of the perforating roller portion 5.

  The discharge roller unit 8 is a roller that presses and discharges the air cap sheet 2 discharged from the peeling unit 7 with a rotation synchronized with the rotation of the punching roller unit 5. This rotation can be synchronized because the rotation shaft of the punching roller unit 5 and the rotation shaft of the discharge roller unit 8 are connected by the belt 8a. Since the outer peripheral surface of the discharge roller portion 8 is covered with rubber, the air cap sheet 2 is difficult to slip. Both ends of the discharge roller portion 8 are rotatably supported by a discharge roller support member 8b erected on the base plate 3a.

  The use state of the air cap sheet volume reducing device according to the embodiment of the present invention configured as described above will be described with reference to FIGS.

  First, the motor 6 is started by operating a control unit (not shown). And it adjusts to predetermined rotation speed. The perforation roller unit 5 rotates counterclockwise as viewed from the front by the rotation of the motor 6. That is, the perforation roller unit 5 rotates so that the wire brush 5 b moves from the bottom to the top with respect to the peeling unit 7.

  The operator inserts the end portion of the air cap sheet 2 between the perforation roller portion 5 and the mesh portion 4b from the introduction guide portion 4a side. Since the introduction guide portion 4a side of the wire brush 5b rotates so as to move from top to bottom, when the tip of the wire brush 5b is caught on the end portion of the air cap sheet 2, the air cap sheet 2 5 is conveyed so as to be caught up.

  The tip of the wire brush 5b pierces the convex part 2a of the air cap sheet 2 and is inserted into the hole (mesh) of the net part 4b of the traveling guide part 4 as it is, so that holes are formed in the upper part and the lower part of the convex part 2a.

  In this wire brush 5b, the wires are implanted at intervals smaller than the size of the convex portion 2a, and are provided on the outer peripheral surface of the roller body 5a. Therefore, the tips of the wires of the plurality of wire brushes 5b are stuck into the convex portion 2a. Therefore, the air contained in the convex part 2a escapes. Further, the discharge guide portion 4c of the travel guide portion 4 includes a spring 4d that the travel guide portion 4 urges in the vertical direction from the lower side of the air cap sheet 2, so that the upper surface of the travel guide portion 4 is conveyed. The pressing force of the perforating roller unit 5 is increased against the air cap sheet 2.

  Further, due to the pressing force when the wire tip of the wire brush 5b pierces the convex portion 2a of the air cap sheet 2, the peripheral portion of the convex portion 2a expands and the convex portion 2a attempts to sink into the mesh of the net portion 4b. To do. However, since the mesh provided in the mesh portion 4b is smaller than the projection 2a of the air cap sheet 2, the projection 2a is prevented from sinking into the mesh of the mesh portion 4b. The tip of the wire brush 5b can be pierced into the protrusion 2a.

  Even when the tip of the wire brush 5b does not pass through the mesh hole of the mesh part 4b of the traveling guide part 4 and comes into contact with the mesh of the mesh part 4b, the wire of the wire brush 5b is an elastic wire. Therefore, if it rotates in the bent state and leaves | separates from the traveling guide part 4, it will return to the original straight state. Since the mesh part 4b is formed of a metal mesh, the wire brush 5b is less likely to be bent in contact with the mesh part 4b than using punching metal, so that the load on the wire brush 5b is reduced. It is desirable to use a wire mesh as the portion 4b.

  The air cap sheet 2 pierced by the wire brush 5 b of the punching roller unit 5 is conveyed along with the rotation of the roller unit 5. Then, the end portion of the air cap sheet 2 comes into contact with the end portion of the lower surface of the peeling portion 7, and the air cap sheet 2 is pulled away from the perforating roller portion 5 that tries to wind the air cap sheet 2 with the rotation of the wire brush 5 b. It is.

  Since the protruding portion 7a is provided on the punching roller portion 5 side of the peeling portion 7, and this protruding portion 7a is disposed so that the tip portion thereof is buried in the wire brush 5b of the punching roller portion 5, The air cap sheet 2 can be surely peeled off from the perforation roller portion 5 that is about to be wound when the wire pierces the air cap sheet 2.

  Since the perforation roller unit 5 rotates and sequentially conveys the air cap sheet 2, the air cap sheet 2 separated from the wire brush 5 b by the peeling unit 7 passes through the lower surface of the peeling unit 7 and is sent out. .

  The air cap sheet 2 that has passed through the peeling portion 7 is sent to the discharge roller portion 8. With the pressing force sandwiched between the discharge guide portion 4c and the discharge roller portion 8, the air remaining on the convex portion 2a of the air cap sheet 2 is completely discharged. Since the rotation of the discharge roller unit 8 is synchronized with the rotation of the punching roller unit 5, the air cap sheet 2 is not wound around the punching roller unit 5, and the punching roller unit 5 and the discharge roller unit 8 The paper can be discharged from the discharge roller portion 8 without accumulating in the middle.

  When getting used to the volume reduction operation of the air cap sheet 2, it is possible to operate the control unit to increase the rotation speed of the perforating roller unit 5 and improve the efficiency of the operation.

  Since the present invention is simply provided with a perforation roller portion provided with a brush-like member on its outer peripheral surface on a base table provided with a traveling guide portion, the structure is simple and the production cost can be reduced. It is suitable for a volume reducing device for an air cap sheet having a convex portion containing air.
