2. Description of the Related Art As a device of this type, there is a simple toilet as shown in FIG. In this simple toilet, the vinyl tube 101 is folded into a ring to
01 is arranged around the funnel-shaped cylindrical body 102, and the tube 1
01 is guided from the upper side to the lower side of the cylindrical body 102. Below the cylindrical body 102, a pair of holding plates 103 are provided, and the tube 101 is held between the holding plates 103. The respective heaters are provided on the edges of the sandwiching plates 103. These heaters are temporarily heated to weld the tube 101 and seal the tube 101.

Two sets of rollers 104 and 105 are arranged below each holding plate 103. The pair of rollers 104 on the right side sandwiches the right edge of the tube 101, and the pair of rollers 105 on the left side sandwiches the left edge of the tube 101.

Here, when the human waste falls from the toilet seat 106 to the inside of the tube 101, the human waste is collected in the tube 101.
Of the holding plate 103, that is, the holding plate 103. When the pedal 107 is depressed in this state, in response to this, the holding plates 103 are opened and the two sets of rollers 10 are
4, 105 rotate and pull down the tube 101.
The pulling down of the tube 101 is performed until the human waste inside the tube 101 comes to the lower side of each holding plate 103.
After that, the holding plates 103 are closed, and the heaters of the holding plates 103 generate heat to seal the tubes 101. Therefore, the human waste inside the tube 101 is sealed between the two upper and lower sealing portions.

Such a process is repeated, and the tube 101 in which human waste is sealed is stored in the container 108.

[0006]

However, in the above-mentioned conventional apparatus, since the tube 101 is sealed while the tube 101 is inflated, a large amount of air is sealed inside the tube 101 together with the human waste. As a result, the used tube 101 became bulky, and the container 108 for storing the tube 101 soon became full. Further, when a large amount of air is sealed inside the tube 101, it becomes difficult to process the tube 101, that is, to collect and incinerate the tube.

Further, since the tube 101 is heated and welded by the heater, equipment for supplying electric power is required,
The location of this toilet was limited.

Therefore, an object of the present invention is to provide a sealing processing device capable of sealing the tube while expelling the air inside the tube.

[0009]

In order to solve the above-mentioned problems, according to the present invention, a tube made of a flexible sheet is pulled up by hand and folded into an annular shape, and the annular sealing element is arranged at the center. And a pair of cams arranged side by side below the introduction frame. Each cam has a pillar portion axially supported and a plurality of blades radially protruding from the pillar portion. Hold the tube of the sealing member from above the introducing frame through the inside of the introducing frame and between the cams, and bite each blade of these cams with the tube of the sealing member sandwiched between these cams. In addition, the tube of the sealing member is pulled down by rotating these cams.

Further, a pressing means for pressing the respective cams against each other is further provided.

Further, each strip-shaped elastic body is attached to the end of each wing plate of each cam.

[0012]

In the present invention, with the tubes of the sealing member sandwiched between the cams, the blades of the cams are engaged with each other and the cams are rotated to pull down the tube of the sealing member. There is. Therefore, if dirt such as dust or human waste is contained in the tube, the tube can be pulled down while crushing the dirt between the cams and expelling the air inside the tube. The tube is sandwiched between the cams and sealed by the engagement of the vanes of the cams.

Further, according to this invention, there is further provided pressing means for pressing the respective cams against each other. This ensures that the tube between the cams is sealed.

Further, according to the present invention, the strip-shaped elastic bodies are attached to the ends of the blades of the cams. Therefore, the tube between the cams is tightly sealed by these elastic strips.

[0015]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a main mechanical portion 1 according to one embodiment of the present invention, and FIG. 2 shows the main mechanical portion 1 partially broken.

In the main mechanism portion 1, a first cam 11 and a second cam 12 are supported between the two support plates 10a and 10b. Both ends of the shaft 13 of the first cam 11 are inserted into the small holes of the support plates 10a and 10b, whereby the first cam 11 is rotatably supported. Also,
Both ends of the shaft 14 of the second cam 12 are connected to the support plates 10a, 10a.
The second cam 12 is rotatably supported so as to be movable along the long holes 15a and 15b.

Both ends of the shaft 13 of the first cam 11 and both ends of the shaft 14 of the second cam 12 are connected by two coil springs 16. These coil springs 16 attract the movable second cam 12 to the first cam 11 side.

Further, the drive shaft 17 has the support plates 10a and 10a.
It is rotatably supported by b. This drive shaft 17
A lever 18 is fixed to one end of the coil, a coil spring 19 is fitted to the other end, and a sector gear 21 is fixed. The fan gear 21 meshes with an interlocking gear 22 fixed to the end of the shaft 13 of the first cam 11.

FIG. 3 schematically shows the main mechanical section 1 as viewed from the side. As is apparent from FIG. 3, one end 19a of the coil spring 19 is hooked on the recess 21a of the fan gear 21, and the other end 19b of the coil spring 19 is hooked on the protrusion 23 protruding inward from the support plate 10a. The coil spring 19 biases the fan gear 21 in the direction of arrow A until the fan gear 21 contacts the protrusion 23.

When the lever 18 is rotated in the direction of arrow B, the sector gear 21 also rotates in the same direction, and the interlocking gear 22 and the first cam 11 rotate in the direction of arrow C.
Along with this, the second cam 12 rotates in the direction of arrow D.

Thereafter, when the lever 18 is released, the elastic force of the coil spring 19 causes the fan gear 21 to rotate in the direction of arrow A until it comes into contact with the projection 23. Along with this, the lever 18 also rotates in the same direction and returns to the original position. At this time, the interlocking gear 22 rotates in the direction opposite to the arrow C, but the first cam 11 does not rotate and maintains the stopped state.
The second cam 12 is also stopped.

Therefore, only the rotation of the interlocking gear 22 and the shaft 13 in the direction of the arrow C is transmitted to the first cam 11, and the rotation in the opposite direction is not transmitted. In order to transmit only this one-way rotation, for example, a one-way clutch is built in the first cam 11, and the first cam 11 is connected to the shaft 13 via the one-way clutch.
Connected to. Moreover, you may apply the ratchet mechanism applied to the micrometer.

FIG. 4 shows the first and second cams 11 and 12. As shown in FIG. 4, the first and second cams 11 and 12 have a substantially star-shaped cross-section and mesh with each other.

The first cam 11 has a column portion 2 through which the shaft 13 penetrates.
4 and five blades 2 radially projected on the pillar portion 24
5, elastic bands 26 made of rubber attached to the ends of these blades 25, and covers 2 at both ends of the first cam 11.
7 and the interlocking gear 22 and the shaft 1 as described above.
The column portion 24 has a built-in one-way clutch that transmits only the one-way rotation of No. 3 to the first cam 11.

In a similar manner, the second cam 12 has a pillar portion 28 through which the shaft 14 penetrates, five blades 29 radially provided on the pillar portion 28, and end portions of these blades 29. Each elastic band 31 made of rubber is attached, and each cover 32 at both ends of the second cam 12 is provided.

Since the second cam 12 is attracted to the side of the first cam 11 by the coil springs 16 as described above, the blade of one cam is located between the two blades of the other cam. Enter the first and second cams 11, 12
Mesh with each other. Therefore, when the first cam 11 rotates in the direction of arrow C, the second cam 12 rotates in the direction of arrow D.

Now, the main mechanism section 1 is incorporated in a simple toilet 51 as shown in FIG. 5, for example. The simple toilet 51 is an example of the sealed processing device of the present invention.

In this simple toilet 51, a partition plate 53 is provided inside the support housing 52, and the main mechanism section 1 is disposed under the partition plate 53. A hole 53a is formed in the partition plate 53, and the hole 5a
The first and second cams 11, 1 of the main mechanical unit 1 are provided under 3a.
2 is located.

The lever 18 of the main mechanism portion 1 is provided with the support housing 5
2 and is passed through a frame frame 54 fixed to the wall of the support housing 52. The frame frame 54 limits the rotation angle of the lever 18.

On the periphery of the hole 53a of the partition plate 53, a toilet 55 is provided so as to project. An annularly folded tube 56 is arranged on the partition plate 53, and the toilet 55 is located at the center of the annular shape. From above, toilet bowl cover 5
7 is covered.

The tube 56 is made of a thin synthetic resin sheet, and the tube 56 is folded in an annular shape by pulling the tube 56 by hand.

A storage case 58 is provided below the support case 52. The storage case 58 has a drawer 59. In addition, a hole 58a is formed in the upper plate of the housing 58, and the first mechanical part 1 of the main mechanism portion 1 is formed on the hole 58a.
And the 2nd cams 11 and 12 are located.

FIG. 6 shows the simplified toilet 51 as viewed from the side. As is clear from FIG. 6, the annularly folded tube 56 passes through the inside of the toilet bowl 55 via the upper peripheral edge of the toilet bowl 55 and is guided to the main mechanism section 1. Then, the tube 56 passes between the first and second cams 11 and 12 of the main mechanism portion 1, reaches the drawer 59 of the housing 58, and is stored therein.

Next, the procedure for using this simple toilet 51 will be described.

First, one end of the tube 56 is pulled out upward from the periphery of the toilet 55, and this end is sealed. For example, by tying a knot in the tube 56, the tube 5
6 can be sealed. Further, an adhesive may be used, or the tube 56 may be tied up with a string.

The one end of the tube 56 is passed through the inside of the toilet 55, and the first and second cams 11 and 12 of the main mechanism section 1 are passed.
Lead in between, rotate the lever 18 in the direction of arrow B,
The cam 11 is rotated in the direction of arrow C, and the second cam 12 is rotated in the direction of arrow D. This makes this tube 5
One end of 6 passes through between the first and second cams 11 and 12 and is guided to the drawer 59 of the housing 58.

After that, when the toilet 51 is used up, the human waste 61 is collected inside the tube 56 as shown in FIG. 7 (a). At this time, the wing plate 25a of the first cam 11 faces the column portion 28 of the second cam 12, and the second cam 12 is biased toward the first cam 11, so that the first cam The elastic band 26a of the blade 25a of No. 11 is pressed against the column 28 of the second cam 12 via the tube 56. As a result, the tube 56 is sealed between the blade 25a of the first cam 11 and the pillar 28 of the second cam 12, and the human waste 61 is collected above the sealed portion.

A groove is formed at the center of the elastic band for the purpose of tightly sandwiching the tube between the elastic body and the column and sealing the tube securely.

In this state, when the lever 18 is rotated in the direction of arrow B, the first cam 11 moves in the direction of arrow C and the second cam moves in the direction of arrow C as shown in FIGS. 7 (b) and 7 (c). 12 rotates in the direction of arrow D, and the first and second cams 1
The tube 56 between 1 and 12 is pulled down.

Since the blades 25 of the first cam 11 and the blades 29 of the second cam 12 mesh with each other,
While crushing the human waste of the tube 56, the tube 56
The tube 56 is pulled down while pushing out the air. Therefore, the tube 56 led out below the first and second cams 11 and 12 contains almost no air,
Only human excrement enters.

The lever 18 supports the frame 5 of the support housing 52.
4 until it comes into contact with the blade 4 of the first cam 11.
From the state in which 5a faces the column portion 28 of the second cam 12 to the state in which the next blade 25b faces the column portion 28, until the state in which the next blade 25c faces the column portion 28, The first and second cams 11 and 12 rotate. In other words, one operation of the lever 18 causes the blades 25a to 25
The first cam 11 rotates by an angle reaching the blade 25c through b, and the second cam 12 rotates by the same angle accordingly. As a result, as shown in FIG.
The human waste is completely guided under the first and second cams 11, 12.

When the rotation of the first and second cams 11 and 12 is completed, the wing plate 25c of the first cam 11 faces the column portion 28 of the second cam 12 via the tube 56, and the tube 56 is removed. It is sealed. As a result, the human waste is sealed in the tube 56, and the human waste and its odor are collected in the tube 5.
It does not leak from 6.

Thereafter, when the lever 18 is released, the sector gear 21 rotates in the direction of arrow A by the elastic force of the coil spring 19 shown in FIG. 3 as described above, and the lever 18 returns to the original position. Along with this, the interlocking gear 22 and the shaft 13 rotate, but this rotation is not transmitted to the first cam 11, and the first and second cams 11 and 12 maintain a stopped state. Therefore, the state shown in FIG. 7D is maintained.

Similarly, every time the toilet 51 is used, the lever 18 is rotated in the direction of the arrow B, and together with the tube 56, the human waste of the tube 56 is pulled down, and the human waste is collected in the tube 56. To be sealed.

As described above, in the main mechanism portion 1, the first and second cams 11 and 12 are engaged and rotated, and the tube 56 between the first and second cams 11 and 12 is pulled down while the inside of the tube 56 is Push air out, tube 5
Only 6 human waste is sealed.

FIG. 8 shows a modification of the main mechanism section. Here, instead of the lever 18 shown in FIG. 1, a pedal 62 is fixed to one end of the drive shaft 17, and a large diameter gear 63 is fixed to the other end of the drive shaft 17 instead of the sector gear 21. Further, the small diameter gear 64 and the large diameter gear 63 and the interlocking gear 2
The small diameter gear 64 is interposed between the two and is rotatably attached to the support plate 10a.

With such a structure, the pedal 62 is depressed as shown in FIG.
When rotated in the direction of, the large diameter gear 63 also rotates in the same direction, the small diameter gear 64 rotates in the direction of arrow F, and the interlocking gear 22 and the first cam 11 rotate in the direction of arrow C.
As a result, the tube between the first and second cams 11 and 12 is pulled down.

Thereafter, when the pedal 62 is released, the pedal 62 is pulled up by the coil spring 65 hung between the pedal 62 and the support plate 10b to return to the original position. Along with this, the large diameter gear 63 and the small diameter gear 64 also rotate in the reverse direction, but the first and second cams 11 and 12 maintain the stopped state.

FIG. 10 shows another modification of the main mechanism section. In this main mechanism part, the lever 18 shown in FIG.
Instead of, a pedal 66 is provided. This pedal 66
Is directly connected to the sector gear 21 and these pedals 6
6 and the fan-shaped gear 21 are integrated. This pedal 66
When stepping on, the fan gear 21 rotates and the first cam 11
Rotates in the direction of arrow C, the second cam 12 rotates in the direction of arrow D, and the tube is pulled down. When the pedal 66 is released, the elastic force of the coil spring 19 causes the pedal 66 to return to its original position.

In the embodiments described above,
As the cam, the one having five blades is shown as an example.
The number of blades may be increased or decreased. Further, the shape of the wing plate may be appropriately modified.

Further, a motor may be used to rotate each cam. In this case, although power equipment is required as in the conventional device shown in FIG. 10, this invention is clearly different from the conventional device in that the tube is sealed while expelling the air inside the tube. In contrast, the device of this invention is superior.
