The casing 11 takes the shape of a box and has an input port 11c, an outlet port 11e, and an exhaust port 11g. The inlet 11c is a hole through which an object to be sealed (hereinafter referred to as waste) is put, and the outlet 11e is a passage through which the waste sealed in the sealing film 29 escapes. A collection space 11f is provided below the outlet 11e. The collection space 11f is a space where fallen sealed waste stays until it is collected. The exhaust port 11g is a passage through which air purified inside the casing 11 is discharged.

In addition, a control unit 13 is installed on the upper portion of the casing 11 . The controller 13 controls the overall operation of the automatic sealing device 10 . The shape of the controller 13 can be variously changed in consideration of the overall design of the casing 11 .

Inside the casing 11, an air circulator 15 and a sterilizer 16 are installed. The air circulator 15 circulates the air inside the casing space 11a so that the air does not become stagnant. In addition, the sterilizer 16 removes microorganisms or odors contained in the air generated before sealing the waste. Sterilization or odor removal methods can be applied in various ways. Eventually, the air inside the casing 11 is purified by the fan filter 25 and the sterilizer 16 and then discharged through the exhaust port 11g.

Meanwhile, the odor inducing structure 21 is fixed to the upper portion of the space 11a. The odor inducing structure 21 is made of a metal plate and has a vertical passage 21a on one side. The vertical passage 21a is a hole through which waste passes downward. In addition, a through hole 21c is located on the other side. The through hole 21c is a passage through which the odor rising from the vertical passage 21a is sucked down to the fan filter 25 .

The film supply unit 27 is installed inside the vertical passage 21a and provides a sealing film 29 covering the waste that has fallen through the inlet 11c, and has a cartridge 27a shown in FIG. 8a. . The cartridge 27a waits with the sealing film (29 in Fig. 8a) to seal the injected waste open. The structure of the film supply unit 27 is separately shown in FIGS. 8A and 8B.

The sealing film 29 in this embodiment is a two-ply vinyl film having a constant width and extending in the longitudinal direction (direction perpendicular to the width direction). In particular, both ends in the width direction are integral. Therefore, when the overlapping sealing films 29 are opened, a continuous passage in the longitudinal direction is created. The waste is accommodated inside the opened sealing film (29).

This sealing film 29 is repeatedly folded into an open state through a separate vinyl folding device, as shown in FIG. 8B, and stored in the cartridge 27a. The sealing film 29 is drawn out through the take-out slit 27c provided in the cartridge 27a. For example, when the sealing film 29 is pulled in the direction of arrow d, it is withdrawn through the withdrawal slit 48c.

The cartridge 27a is a ring-shaped container made of plastic, with a central portion pierced upward and downward. The falling processing object passes through the center of the cartridge 27a. The waste passes downward through the cartridge 27a (with the lower end already sealed) and is contained in a waiting sealing film 29. In FIG. 8A, the lower end of the sealing film 29 is shown in an open state, but this is a view for explaining the structure of the sealing film, and is actually blocked by the fusion line 29d.

The compression unit 50 is installed at the bottom of the film supply unit 27, and presses the waste in the direction of arrow p in FIG. 3 in a state where the sealing film containing the waste (z in FIG. It acts as a compression. The reason for compressing the object to be treated is to reduce the volume of the object to some extent and to close the sealing film 29 that is open upward.

The compression unit 50 includes a support plate 52, a pressing means, and a first driving unit.

The support plate 52 is a pair of plate-like members disposed spaced apart with the waste descending path interposed therebetween. (See FIG. 5) The support plate 52 takes the shape of a square plate and is fixed to an appropriate bracket (not shown) inside the casing 11 to maintain a vertical state.

The pressurizing means is installed between the support plates 52 and serves to pressurize the sealing film and the waste in a state in which the sealing film containing the waste is lowered.

These pressing means include four compressed lead screws 53, a first carrier 53e, a second carrier 53f, a first reciprocating plate 56a, a second reciprocating plate 56b, and pressurizing sponges 55a and 55b. ) is provided.

The crimping lead screws 53 are installed so that both ends can pivot on the support plate 52, and two on the upper side and two on the lower side of the support plate 52 are horizontally arranged in parallel. The upper two crimp lead screws 53 and the lower two crimp lead screws 53 have the same height. In addition, the upper and lower compression lead screws are located in the vertical direction. An imaginary straight line connecting the crimped lead screw forms a rectangle.

In addition, a left-hand thread 53a and a right-hand thread 53b are formed in the compression lead screw 53 . That is, a left-hand thread 53a is formed on one side and a right-hand thread 53b is formed on the other side based on the central portion in the longitudinal direction. The left-hand thread 53a and the right-hand thread 53b are opposite only in the spiral direction, and the pitch interval or height of the threads is the same.

The first carrier 53e is a nut-shaped member that meshes with the left-hand thread 53a and linearly moves according to the axial rotation of the compression lead screw, and is coupled with the first reciprocating plate 56a. In addition, the second carrier 53f meshes with the right-hand thread 53b and is coupled to the second reciprocating plate 56b as a nut-shaped member that linearly moves according to the axial rotation of the crimping lead screw. Needless to say, the first carrier 53e and the second carrier 53f move forward and backward according to the shaft rotation of the crimping lead screw 53.

The first reciprocating plate 56a and the second reciprocating plate 56b are vertical rectangular plates having a predetermined thickness. The first and second reciprocating plates 56a and 56b move forward and backward according to the axial rotation of the compression lead screw 53.

In addition, pressure sponges 55a and 55b are fixed to opposite surfaces of the first and second reciprocating plates 56a and 56b. The pressure sponges 55a and 55b take the shape of a block having a certain thickness and elastically press the waste material Z accommodated in the sealing film 29 . The reason for pressing the waste is to reduce the volume of the waste to some extent.

The first driving unit moves the opposing pressure sponges 55a and 55b forward and backward, and includes a motor 51, a drive pulley 51a, a driven pulley 53c, and a timing belt (54 in FIG. 4).

The motor 51 operates under the control of the controller 13 to rotate the driving pulley 51a in both directions. The driven pulley 53c is a member fixed to the end of each compression lead screw 53, and is connected to the driving pulley 51a through a timing belt 54.

As shown in FIG. 4, the driving pulley 51a is connected to the lower two driven pulleys 53c, and the lower two driven pulleys are connected to the upper driven pulley 53c. In this state, when the drive pulley 51a rotates clockwise, for example, all driven pulleys 53c rotate in the same direction.

On the other hand, the sealing and cutting unit 30 forms two rows of fusion lines (29d in FIG. 9) in the sealing film 29 while the compression unit 50 compresses the waste z, and As for cutting between, it has a housing 32, first and second fusion cutters 35 and 37, and a fusion cutter driver.

The housing 32 is located between the film supply unit 27 and the compression unit 50, and passes down the falling waste contained in the sealing film. The housing 32 may be fixed to an upper end of the support plate 52 .

The first fusion cutter 35 and the second fusion cutter 37 oppose each other and can move forward and backward. The first and second fusion cutters 35 and 37 come close to each other with the sealing film 29 interposed therebetween, form fusion lines 29d by bringing the sealing film over the housing into close contact, and cut between the fusion lines.

9 is a view showing a state after the sealing film 49 is fused using the sealing and cutting parts.

As shown, two rows of fusion lines 29d and one cutting line 29e are formed on the sealing film 29 . The fusing line 29d and the cutting line 29e are simultaneously formed by heat-pressing of the first fusing cutter 35 and the second fusing cutter 37, and are formed at a higher position than the object Z to be treated.

For convenience of description, although the cutting line 29e is shown as a solid line in FIG. 5, the cutting line 29e does not remain, but is a cutting line separating the upper envelope 29a and the lower envelope 29b. Fusion and cutting are performed simultaneously. Therefore, when the first fusion splicing cutter 35 and the second fusion splicing cutter 37 are spaced apart, the lower bag 29b (in which the waste is sealed) immediately falls.

Among the two rows of fusion lines 29d, the upper fusion line seals the lower end of the upper bag 29a, and the lower fusion line seals the upper part of the lower bag 29b in which the object Z is accommodated. . The upper bag 49a is opened to the top in an empty state and waits for waste to be put into it.

Two fused lead screws 33 form a pair and are spaced apart in parallel, and both ends are axially supported by the housing 32 . In addition, a left-hand thread 33a and a right-hand thread 33b are formed in the fused lead screw 33 . A left-hand thread 33a is formed on one side and a right-hand thread 33b is formed on the other side, based on the central portion of the fusion lead screw 33 in the longitudinal direction.

The nut portions 35b and 37b are nut-shaped members that mesh with the fusion lead screw 33, and the nut portion 37b fixed to the second fusion cutter 37 meshes with the left-hand thread 33a, and the first fusion The nut portion 35b mounted on the cutter 35 engages the right-hand thread 33b. The nut parts 35b and 37b move forward and backward with respect to each other by the axial rotation of the fusion lead screw 33.

The second driving unit rotates the fusion lead screw 33 in the same direction at the same time, and includes a motor 31, a driving pulley 31a, a driven pulley 33d, and a timing belt (34 in FIG. 4). The motor 31 is operated by the control unit 13 to output bi-directional rotational force. The driven pulley 33d is fixed to the ends of the fused lead screws 33 on both sides and is connected to the drive pulley 31a through a timing belt 34. Eventually, by the operation of the motor 31, the fusion lead screw 33 rotates clockwise or counterclockwise at the same time. Of course, the first fusion cutter 35 and the second fusion cutter 37 move forward and backward according to the rotation of the fusion lead screw 33 .

The operation of the automatic sealing device of the present embodiment having the above configuration is performed as follows.

When the user inputs the waste z through the input port 11c, the waste descends into the upper envelope (29a in FIG. 9) of the airtight film 29 waiting by the film supply unit 27. Since the lower bag 29b has already been cut and collected, the upper bag 29a is waiting in the open state in the drop path of the waste.

When the waste contained in the sealing film 29 further descends and is placed between the pressure sponges 55a and 55b, the compression lead screw 53 is operated by the motor 51 to pressurize the waste. The waste is compressed to some extent by pressing on the pressurized sponge, and the sealing film 29 surrounding the waste is in close contact.

At the same time, the fusion lead screw 33 also operates. When the fusing lead screw 33 operates, the first and second fusing cutters 35 and 37 move simultaneously in directions close to each other, and finally, as shown in FIG. 13B, the opposing strip 37d ) and the fusion band 35t meet to form a fusion line.

In this state, when the fusion lead screw 33 rotates further, the opposing strip 37d pushes the front body 35m up to the support body 35d, as shown in FIG. 13C. As the front body 35m is pushed toward the support body 35d, the cutting wire 35w between the front bodies 35m is exposed and comes into contact with the sealing film 29. The cutting wire 35w is preheated by electric power applied from the outside. The sealing film 29 is melted and cut by the cutting wire.

When the fusion lead screw 33 is reversely rotated after completing the above process, the first and second fusion cutters 35 and 37 are widened, and the sealed waste falls through the discharge port 11e by weight to collect space 11f. ) is located at

In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those skilled in the art within the scope of the technical idea of the present invention.
