Abstract

PROBLEM TO BE SOLVED: To provide a film sealing device and a film fitting method capable of easily fitting a film to a toilet seat device, and a film packing body for use with the device and the method.SOLUTION: A film sealing device includes two pairs of rollers 101 for sandwiching each of two end edges of a film F in a direction orthogonal to a feed direction of the film F and delivering the edges downward. A jig S1 has a shape such that it can be bridged over the two pairs of rollers 101. The jig S1 is installed on a top face of the film F so as to be bridged over the two pairs of rollers 101. With the jig S1 thus installed, the two pairs of rollers 101 are driven in a direction in which the film F is delivered downward. Since the film F is pressed on the rollers 101 by the jig S1, frictional force is generated between the film F and the rollers 101, and the film F is sandwiched between the pair of rollers 101. Thus, only by delivering the film F, the film F can be easily fitted to the rollers 101.SELECTED DRAWING: Figure 14

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings referred to in the description of the present embodiment, X, Y, and Z axes orthogonal to each other are shown for convenience. The XY plane is parallel to the horizontal plane, and the Z-axis direction is the vertical direction.

  FIG. 1A is an exploded perspective view showing the configurations of the film holder H and the film F, and FIG. 1B is a perspective view showing the configurations of the film holder H and the film F.

  The film holder H has an upper frame H1 and a lower frame H2.

  The film F is an opaque resin-made cylindrical film and is previously folded in the outer peripheral direction. The upper frame H1 and the lower frame H2 have a substantially elliptical shape in plan view. A substantially oval opening H1a is formed in the upper frame H1. The upper frame H1 includes a cylindrical portion H1b extending substantially vertically and a flange portion H1c extending outward from the upper end of the cylindrical portion H1b. Moreover, the collar part H1d extended inside is formed in the lower end of the cylinder part H1b.

  A substantially oval opening H2a is formed in the lower frame H2. The lower frame H2 includes a cylinder part H2b extending substantially vertically and a flange part H2c extending outward from the lower end of the cylinder part H2b. A flange portion H2d extending inward is formed at the upper end of the cylindrical portion H2b. A recess H2e is formed on the surface on the negative side of the Z-axis of the flange H2c.

  When assembling the film holder H, the cylindrical portion H1b of the upper frame H1 and the cylindrical portion H2b of the lower frame H2 are passed through the film F so that the film F is sandwiched from above and below. Within the film F, the flange portion H1d of the upper frame H1 and the flange portion H2d of the lower frame H2 are combined. In this state, the flange portion H1d of the upper frame H1 and the flange portion H2d of the lower frame H2 are heat-welded. Thereby, the film F, the upper frame H1, and the lower frame H2 are integrated.

  FIG. 2A is a perspective view showing the configuration of the film holder H in which the upper frame H1 and the lower frame H2 are integrated. FIG. 2B is a cross-sectional view of the film holder H shown in FIG. 2A cut along a plane parallel to the XZ plane at the center position in the Y-axis direction when viewed in the Y-axis positive direction. 2A and 2B, the film F is not shown for convenience.

  Referring to FIG. 2A, inclined portions H1e and H1f and a wall portion H1g are formed between the flange portion H1c and the cylindrical portion H1b of the upper frame H1. As shown in FIG. 2B, the inclined portions H1e and H1f are inclined so that the upper portion is widened, and the wall portion H1g is substantially parallel to the Z-axis direction. The inclined part H1f has a larger inclination angle than the inclined part H1e. The wall H1g has a certain width in the Z-axis direction. A predetermined gap is formed between the flange portion H1c of the upper frame H1 and the flange portion H2c of the lower frame H2. The film F shown in FIG. 1 is attached to this gap. With the film F mounted on the outer periphery of the cylindrical portion H1b of the upper frame H1 and the cylindrical portion H2b of the lower frame H2, the edge on the Z-axis positive side of the film F is drawn upward by a predetermined amount, and the opening H1a, It is passed downward through the opening H2a. Thus, the film F is set on the film holder H as shown in FIG.

  FIG. 3 is a perspective view showing the structure of the mechanical structure 10 and the support 20 of the toilet seat device.

  The mechanical component 10 includes a base 11, a mechanism unit 12, and a guide 13. The base 11 is provided with an upper surface 11a parallel to the horizontal plane, an opening 11b penetrating the base 11 in the vertical direction, and a plurality of convex portions 11c projecting to the Z axis positive side. A guide portion 11d that widens the opening 11b in the X-axis direction is formed at the center in the Y-axis direction of the opening 11b. The mechanism unit 12 is installed on the lower surface side of the base 11 and is connected to a circuit board (not shown) installed on the base 11. The guide 13 is installed on the lower surface side of the base 11 so that the upper surface is inclined with respect to the horizontal plane.

  As shown in FIG. 3, the support 20 has a recess 20a, and an opening 20b is formed on the bottom surface of the recess 20a. A hole 20 c is formed on the upper surface of the support 20. A switch 21 for operating the mechanical component 10 is installed on the front surface (Y-axis negative side) of the support 20. The mechanical structure 10 is installed on the support 20 so as to be fitted into the recess 20a. The switch 21 is connected to the circuit board of the mechanical component 10.

  After the mechanical component 10 is installed in this way, as shown in FIG. 4, the seat frame 31 is installed on the support 20 so as to cover the mechanical component 10, and the toilet seat 35 is installed. . The seating surface frame 31 has a configuration in which a back surface portion 31b is integrally formed at the rear portion of the horizontal portion 31a. The toilet seat 35 is fitted into a recess formed in the horizontal portion 31a. The backrest 32 is installed by the hook portion 32 a being hung on the back surface portion 31 b of the seat frame 31. Further, the armrests 33, 34 are installed on the support 20 by inserting shafts (not shown) on the lower surfaces of the armrests 33, 34 into the holes 20 c (see FIG. 3) of the support 20. A cover 36 is installed so as to cover the opening 35 a of the toilet seat 35. Thus, the toilet seat device 1 is assembled.

  When the toilet seat apparatus 1 is used, as shown in FIG. 5, the toilet seat 35 and the cover 36 are removed, and the film holder H and the film F shown in FIG. 1B are set on the mechanical component 10. Thereafter, the end portion of the film F is attached to the mechanism portion 12 of the mechanical structure 10.

  FIG. 6A to FIG. 8 are diagrams illustrating the operation of the mechanism unit 12 during the excretion process. FIGS. 6A to 8 are cross-sectional views of the film holder H and the mechanical component 10 cut along a plane parallel to the YZ plane. The broken line shows the film F sandwiched between two rollers 101 on the X axis positive side.

  With reference to FIG. 6A, the mechanism unit 12 includes a film feed mechanism 100 and a seal mechanism 200.

  The film feeding mechanism 100 includes a roller 101 and a driving mechanism for driving the roller 101. The drive mechanism includes a motor and a transmission gear. The film feeding mechanism 100 feeds the film F in the Z-axis direction with the edges on both sides of the X-axis of the film F being sandwiched. The seal mechanism 200 includes a shaft 211, a heating mechanism 220 including a heater 221, a crimping mechanism 230 including a crimping portion 231, and a peeling mechanism 240 including a rubber 241. The shaft 211 and the heating mechanism 220 are fixed to the base 11. The crimping mechanism 230 and the peeling mechanism 240 are supported by the shaft 211 so as to be slidable. The peeling mechanism 240 includes a rubber 241. The rubber 241 is supported by a spring so as to be movable in the Y-axis direction.

  As shown in FIG. 6A, in the initial state of the excretion process, the film F is sandwiched between two sets of rollers 101 at both edges on the X axis. The bottom of the film F is positioned at a height around the heater 221. The bottom of the film F is in close contact during initial setup or the previous sealing operation. In this state, excreta and the like are accommodated in the film F.

  When the operator or user inputs an instruction to end excretion via the switch 21 (see FIG. 5) after excretion, the motor (not shown) is driven a predetermined number of steps, and the film F is moved downward by the two sets of rollers 101. (Z-axis negative direction). As a result, the state shown in FIG. Thereafter, a motor (not shown) is driven a predetermined number of steps, and the crimping mechanism 230 is sent in the positive direction of the Y axis from the separated position. Thereby, the film F is pushed by the crimping | compression-bonding part 231, and is brought near to the Y-axis positive direction. Further, when the crimping mechanism 230 is sent in the positive direction of the Y-axis, the crimping portion 231 comes into contact with the rubber 241 of the peeling mechanism 240 via the film F and resists the repulsive force of a spring (not shown). The peeling mechanism 240 is pushed in the Y axis positive direction. Further, when the crimping portion 231 is sent in the positive direction of the Y-axis, the crimping mechanism 230 reaches the crimping position as shown in FIG. 7A, and the crimping portion 231 and the heater 221 are in close contact with each other via the film F.

  In this state, a motor (not shown) is driven again for a predetermined number of steps, and the film F is slightly fed downward. Thereby, as shown in FIG.7 (b), the film F above the crimping | compression-bonding part 231 and the heater 221 is loosened. Thereafter, the heater 221 is driven and the film F is melted. The crimping portion 231 is provided with a protrusion extending in the X-axis direction at the center in the Z-axis direction. The film F is cut by the protrusions. The lower part of the ridge of the film F is welded, and the upper part of the film F in which excreta and the like are stored is sealed. Moreover, the upper part of a protrusion is welded to the film F, and the lower bottom of the film F for accommodating excrement etc. is formed next.

  When the sealing and cutting of the film F are completed, the pressure-bonding mechanism 230 is returned to the Y-axis negative direction. Thereby, the crimping | compression-bonding part 231 leaves | separates from the heater 221 and the rubber | gum 241, and the peeling mechanism 240 is sent to a Y-axis negative direction only a predetermined width with a spring (not shown). At this time, the film F brought into close contact with the crimping portion 231 and the heater 221 is moved toward the Y-axis negative side by a predetermined width from the position of the heater 221 by the peeling mechanism 240. Thereby, even when the film F is attached to the heater 221, the film F is peeled off from the heater 221. Thus, as shown in FIG. 8, the sealed film F falls through the opening 30 b (see FIG. 3) of the support 30. By installing a box or the like for collecting the sealed film F at a position where the sealed film F falls, an operator can easily collect the sealed film F.

  By the way, the film holder H and the film F are attached to the toilet seat device 1 on the user side. Since the film F is a consumable member, after the film F has been used, it is necessary to replace the film F on the user side.

  FIG. 9 is a diagram illustrating an appearance of the package B in which the film F is packed. When the film F is replaced, the user receives a package B shown in FIG. 9 from the manufacturer. FIG. 9 shows a state where the upper lid is removed from the package B. The package B is configured by enclosing a film pack FP and a jig S1 in a rectangular parallelepiped outer box B1 made of cardboard.

  10 and 11 are diagrams showing a process of attaching the film holder H. FIG.

  As shown in FIG. 10, the film pack FP is placed on the base 11 of the mechanical structure 10 with the toilet seat 35 and the cover 36 removed. The film pack FP is a film exchange member that includes a package P that holds the film F and the film holder H. The package P is a cardboard packaging member that holds the film holder H. A mark A indicating the position of the roller 101 (see FIG. 6) is printed on the package P.

  Thus, the film F is mounted on the roller 101 using the jig S1 bundled with the packing body B in a state where the film pack FP is placed on the toilet seat device 1. Thereafter, the package P is pulled upward. As a result, the package P is removed from the film holder H as shown in FIG. In addition, after removing the package P, the film F may be attached to the roller 101 using the jig S1. Alternatively, as shown in FIG. 4, after the toilet seat 35 is mounted, the film F may be mounted on the roller 101 using the jig S1. A method for attaching the film F will be described later with reference to FIGS.

  When the package P is removed from the film holder H, the toilet seat 35 is installed again as shown in FIG.

  Hereinafter, a method for attaching the film F to the roller 101 will be described.

  FIG. 12 is a cross-sectional view showing the configuration of the toilet seat device 1. FIG. 12 is a cross-sectional view of the toilet seat device 1 cut along a plane parallel to the ZY plane as viewed toward the X-axis positive side.

  As shown in FIG. 12, in the state where the film holder H is placed on the base 11, the end of the film F is not sandwiched between the rollers 101. The film F needs to be sandwiched between the rollers 101 on the user side. In the present embodiment, the jig S1 is used when the film F is mounted.

  FIG. 13A is a top view of the toilet seat 35 as viewed from the Z axis positive side. FIG. 13B is a top view of the jig S1 viewed from the Z-axis positive side, and FIG. 13C is a side view of the jig S1 viewed from the X-axis negative side. In addition, in FIG. 13A, illustration of the film holder H and the film F is abbreviate | omitted for convenience.

  Referring to FIG. 13A, the guide portion 11d has a shape recessed outward so that the opening 11b extends in the X-axis direction. The guide portion 11 d is a wall extending upward from the upper surface of the base 11. The Z-axis positive side of the roller 101 is opened by the guide portion 11d. There are a total of four rollers 101, one pair on the X-axis positive side and one pair on the X-axis negative side. A distance W1 in the X-axis direction between the guide portions 11d is slightly larger than a distance W2 in the X-axis direction between the pair of rollers 101 on the X-axis positive side and the pair of rollers 101 on the negative side of the X-axis. Further, the distance D1 in the Y-axis direction of the guide portion 11d is slightly larger than the distance D2 in the Y-axis direction of the two rollers 101 that form a pair.

  Referring to FIG. 13B, the jig S1 is a vinyl chloride rod-shaped member. As shown in FIG. 13C, the cross section of the jig S1 in the YZ plane is substantially circular. The width W3 of the jig S1 in the X-axis direction is slightly larger than the distance W2 between the rollers 101 in the X-axis direction and slightly smaller than the distance W1 between the guide portions 11d in the X-axis direction. A width D3 of the jig S1 in the Y-axis direction is slightly smaller than a distance D1 of the guide portion 11d in the Y-axis direction.

  FIG. 14 is a top view showing a main part of the toilet seat apparatus 1 in a state where the jig S1 is placed on the roller 101. FIG. FIGS. 15A and 15B are cross-sectional views showing a main part of the toilet seat apparatus 1 in a state where the jig S1 is placed on the roller 101. FIG. In addition, in FIG. 14, illustration of the film F is abbreviate | omitted for convenience. FIGS. 15A and 15B are cross-sectional views of the toilet seat device 1 cut along a plane parallel to the ZY plane and viewed toward the X-axis positive side.

  When the film F is mounted on the roller 101, as shown in FIG. 14, the jig S1 is passed through the opening 11b at the position of the guide portion 11d. Thus, the jig S1 is placed on the film F directly above the roller 101 so as to be bridged by the two pairs of rollers. At this time, the jig S1 is positioned in the X-axis direction and the Y-axis direction by the guide portion 11d. As a result, as shown in FIG. 15A, the jig S1 makes point contact with the roller 101 via the film F at the contact points P1 and P2. Thereafter, as shown in FIG. 15B, the roller 101 is driven in the direction of feeding the film F downward. The film F is kept in contact with the roller 101 by the weight of the jig S1. Thereby, a frictional force is generated between the film F and the roller 101, and the edge of the film F is sandwiched between the rollers 101 of each set. Thereafter, when the roller 101 is further driven, the film F is sent downward (Z-axis negative direction). Thus, the film is attached to the roller 101.

<Effect of Embodiment>
According to the present embodiment, the following effects can be achieved.

  As shown in FIG. 15A, the jig S <b> 1 is placed on the roller 101, whereby a frictional force is generated between the film F and the roller 101, and only the film F is sent downward by the roller 101. The film F can be easily set on the roller 101.

  Further, as shown in FIG. 14, since the film F is pressed against the pair of rollers 101 on the positive side of the X axis and the pair of rollers 101 on the negative side of the X axis by the both ends of the jig S1, The film F can be set on these rollers.

  Further, since the film F is opaque, the user cannot visually recognize the roller 101 when the film F is attached to the toilet seat apparatus 1 as shown in FIG. In the present embodiment, as shown in FIG. 10, since the mark A indicating the position of the roller 101 is printed on the package P, the user can easily grasp the position of the roller 101. When the jig S1 is pushed downward at the position of the mark A, the jig S1 is guided to the guide portion 11d. Therefore, the user can easily place the jig S1 on the roller 101.

  Further, since the positional deviation of the jig S1 is regulated by the guide portion 11d, even when the roller 101 is rotated when the film F is attached, the jig S1 can be stably positioned immediately above the roller 101. Thereby, the film F can be set on the roller 101 smoothly.

  Further, as shown in FIGS. 15A and 15B, the jig S1 has a substantially circular cross section, so that even if the jig S1 is rotated by driving the roller 101, the position of the roller 101 and the jig S1 is not limited. The relationship is hard to change. Therefore, a stable frictional force can be generated between the film F and the roller 101, and the film F can be smoothly fed.

  Moreover, since the edge part of the film F is sealed, even if the jig S1 falls, since it is accommodated in the film F, it is easy to pick up the jig S1. For this reason, the operation | work which sets the film F further can be performed easily.

<Example of change>
In the above embodiment, the jig S1 is a rod-shaped member having a substantially circular cross section, but may have other shapes. For example, as shown in FIG. 16 (a), a member having a square cross section may be used, and as shown in FIG. 16 (b), a member having a triangular cross section may be used. However, in the case of the jigs S2 and S3, the jigs S2 and S3 may be separated from the roller 101 due to the rotation of the roller 101. Therefore, as in jigs S4 and S5 in FIGS. 16C and 16D, it is desirable that the contact surface with the roller 101 has an arc shape. Further, as shown in FIG. 16 (e), the jig S6 may have a mid-cavity shape.

  Further, in the above embodiment, as shown in FIG. 13B, the jig S1 has a long bar shape. However, as long as it can be bridged by the two pairs of rollers 101, the jig S1 has another shape. May be.

  In the above embodiment, the jig S1 is formed of vinyl chloride. However, the material forming the jig S1 is not limited to this, and the jig S1 may be formed of a resin material other than vinyl chloride, wood, metal, rubber, or the like. good. The jig S1 needs to have a material and a weight suitable for allowing the film F to slide on the surface of the jig S1 and to be wound into the roller 101 while the film F101 is appropriately pressed by the roller 101. From this viewpoint, the material, shape, and structure of the jig S1 are determined. The jig S1 does not necessarily need to be made of a single material. For example, the jig S1 has various types such as a paper tube covered with a rubber film and an iron core fitted into the paper tube. It may consist of a combination of materials. From the viewpoint of cost and ease of disposal, using a jig S1 made of vinyl chloride as in the above embodiment can be one preferable application example.

  In addition, the jig S1 does not necessarily have to be packaged in the packaging body B that houses the film. For example, when the user receives the toilet seat device 1, the jig S1 may be received together with the toilet seat device 1. However, in this case, if the user loses the jig S1 or cannot find the jig S1 when replacing the film F, the film F cannot be mounted smoothly. On the other hand, in embodiment, since the jig S1 is bundled with the package B which accommodates a film, mounting | wearing of the film F can be advanced smoothly. Further, since the jig S1 is a bar-shaped member made of vinyl chloride, even if the jig S1 is individually packaged in the package B, the cost does not increase so much. Therefore, by bundling the jig S1 as in the present embodiment in the package B, it is possible to improve the convenience for the user while suppressing an increase in cost.

  Moreover, in the said embodiment, the collar part H1d of the upper frame H1 and the collar part H2d of the lower frame H2 are heat-welded in the state which match | combined the collar part H1d of the upper frame H1, and the collar part H2d of the lower frame H2. Thus, the upper frame H1 and the lower frame H2 are integrated. Instead of this, for example, the upper frame H1 and the lower frame H2 may be provided with a concave portion and a convex portion that fit together, and the upper frame H1 and the lower frame H2 may be integrated by fitting the concave portion and the convex portion.

  While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made to the configuration example of the present invention.

  In the above embodiment, the form in which the present invention is applied to the toilet seat device 1 is shown. In addition to the toilet seat device, for example, a dead animal such as a small animal or waste such as garbage is sealed with a film. The present invention may be applied to an apparatus. Moreover, the structure of the film pack FP and the structure of the film holder H can be changed as appropriate. Further, the film holder H may be provided on the toilet seat device 1 side, and the folded film may be attached to the film holder H.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
