Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus (packing apparatus) for bagging waste products such as garbage and commodities.

[0002]

2. Description of the Related Art In various facilities such as hospitals, devices for bagging garbage such as disposable diapers are used. In this conventional apparatus, a long tube-shaped raw film is fed upward toward a garbage inlet, and a bag formed at the same time as forming the bottom of the bag with a bottom heating plate is cut from the tube. Hold the opening edge of the bag in an expanded state, and when the bag is full of garbage, seal the opening of the bag by heat sealing with a hot plate for the mouth, then the bag in which the garbage is stored is The film is removed outside the apparatus and the film is fed out toward the refuse inlet.

[0003]

By the way, naturally, there is a limit to the capacity of the bag (the opening of the bag requires a sealing margin, so the storage limit is smaller than the maximum volume of the bag. ). On the other hand, when the user of the apparatus puts garbage into the bag, the garbage may not always be kept within the bag's storage limit and may be forced into the bag. That is, garbage may be thrown in beyond the storage capacity of the bag.

[0004] For this reason, there has frequently been a case where a sealing allowance for heat sealing cannot be secured at the opening of the bag and sealing cannot be performed. The present invention has been made in view of the above circumstances, and has as its object to provide a bag packing device that allows a user to forcibly push an object such as dust into the mouth of a bag and seal the bag without any trouble. is there.

[0005]

SUMMARY OF THE INVENTION A bag packing apparatus according to the present invention comprises a bag holding means for holding a bag in an open state so that dust and the like can be thrown in, and a bag holding means for holding the bag. And the like, and a sealing means for sealing the bag in a state where the capacity limiting means is released. "

[0006]

According to this structure, the bag held by the bag holding means can be filled only in an amount smaller than the storage limit. In other words, the bag is filled with a sufficient amount of storage. Therefore, even if the user forcibly pushes trash etc. into the bag, the trash etc. will fall to the bottom of the bag when the capacity control means is released, and secure the sealing allowance at the opening. Can be.

In other words, in anticipation of forcibly pushing objects such as refuse into the inlet, the amount of material in the forcibly pushed state is regulated by the capacity regulating means so as to be about the same as the bag storage limit. Thus, the bag can be properly sealed even when the object such as dust is forcibly pushed into the bag. By the way, there is garbage that generates a strong odor when heated, such as disposable diapers generated in hospitals and facilities, and in the case of the above-described heat-sealing type bagging device, the garbage is heated by the heat of the hot platen and the odor is generated. Had the adverse effect of becoming stronger. In this regard, when a non-heating type sealing means is used as in the second aspect, there is an advantage that a bad odor caused by heat can be prevented.

The capacity regulating means can take various forms. However, if a clamping mechanism for sandwiching the bag from both sides is adopted as in claim 2, the remaining capacity of the bag can be secured with a simple structure.

When the feeding bar 20 is located at the top dead center of the orbiting path (at the upper end of the upper sprocket 15),
The bag B is held in a state where the mouth is largely opened upward toward the input port 4 of the main body 2.

As is apparent from the above description, the feeding mechanism including the front and rear endless chains 12 and the feeding bar 20 also serves as the bag holding means described in the claims, and this structure has an advantage that the structure is simplified. There is. In the state where the tip of the bag material A is located at the top dead center of the peripheral circuit of the endless chains 11 and 12, the opening of the second bag B (the point along the sewing machine line C) is located between the upper and lower guide sprockets 19. The endless chain 11 and 12 are interlocked and fixed by the front and rear feeding bar 20, so that the bag raw material A can be intermittently fed by the length of the bag B by rotating the both endless chains 11 and 12 synchronously.

As shown in FIGS. 2 (A), 3 (A), 5 and the like, the front and rear upper shaft 13 is connected via a first motor 22 and a transmission gear 23 provided on the right side plate 2a of the main body 2. Driven individually. The front and rear endless chains 11, 12 may be circulated synchronously by one motor via an interlocking mechanism including a plurality of gears. The front and rear tension sprocket 18 inside the body 2
A clamp mechanism composed of a pair of front and rear clamp bodies 24 is disposed in a portion between the two. This pair of front and rear clamp bodies 24
Is used both as a means for separating the bag B located at the tip of the bag material A from the material web and a capacity regulating means for holding the separated bag B in the raised bottom state. It is wider than the width and is set to fit between the left and right endless chains 11,12.

As shown in FIG. 2A, the upper end of the front and rear clamp body 24 is curved toward the feeding path of the bag material A, while the lower end of the front and rear clamp body 24 has endless chains 11 and 12. A bearing portion 24a extending outward in the left and right directions is provided integrally. The bearing portion 24a is rotatably fitted on a support shaft 25 mounted between the left and right side plates 2a of the main body 2. In addition,
As shown in FIG. 2 (A) and FIG. 4, a horizontal portion 24b overlapping with each other is integrally provided at the right end of the front and rear clamp body 24, and a vertically long first interlocking rod is attached to the front and rear horizontal portion 24b of the clamp body 24.
The upper end of 26 is connected with a pin 27. The pin holes of the front-rear horizontal portion 24b of the clamp body 24 are elongated holes in the front-rear direction. Accordingly, when the first interlocking rod 26 is pulled downward, the front and rear clamps 24 rotate inward so that their upper ends overlap.

The first interlocking rod 26 is connected to the first foot pedal 5
Is connected by a pin 29 to a middle portion of a first rotating rod 28 attached to the front end, and the first rotating rod 28 is attached to the main body 2 with a pin 30 at the front end so as to rotate up and down. Have been. Therefore, when the first foot pedal 5 is depressed with the foot, the front and rear clamp body 24 rotates via the first turning rod 28 and the first interlocking rod 26, and the front and rear clamp bodies 24 move the front and rear clamp bodies 24 to the top of the original bag A. The bottom part of the located bag B is sandwiched from the front-back direction.

In this case, as shown in FIG. 7, in a state where the bag B is held between the front and rear clamp bodies 24, the mating surface of the front and rear clamp bodies 24 is in any of the front and rear directions with respect to the center line of the feeding path of the bag material A. (In the figure, it is shifted to the near side). For this reason, in the state where the front end portion (opening edge) of the second bag B is sandwiched by the front and rear feeding bar 20, the bottom portion of the bag B located at the head is pushed to the front or rear, thereby, The bag material A is cut at the sewing line. That is, the bag B located at the head of the bag material A is cut off.

Further, as shown in FIG.
The holding position of the bag B by 24 is positioned above the bottom by a certain dimension H, so that D can be supplied only in an amount smaller than the storage limit of the bag B (for example, about 80% of the storage limit). ing. In other words, by holding the bag B in the raised bottom shape, the bag has extra storage capacity.
The holding position of the bag B by the clamp body 24 is set to a position where even if the dust D is pushed into the mouth of the bag B, when the holding by the clamp body 24 is released, the entire amount of the dust D is stored without any trouble. Have been.

As shown in FIG. 2A, the base end of the lid 3 is pivotally attached to the main body 2 by a pivot pin 31 so as to be able to flip up and rotate. The tip of the moving rod 28,
A portion of the lid 3 behind the pivot pin 31 is connected to the second interlocking rod.
It is rotatably connected at 32. Accordingly, when the user steps on the first foot pedal 5 with the foot, the front and rear clamp bodies 24 rotate and the bag B is pinched, and at the same time the lid 3 is opened and the dust D can be thrown into the slot 4. become.

Although not shown, the first turning rod 28 is
When the foot pedal 5 is turned downward while being depressed, it is held in a downwardly turned state by an elastic locking mechanism.
When the lid 3 is opened by hand against the elastic force of the locking means, the first
The turning rod 28 returns upward and turns. When the clamping of the bag B by the front and rear clamp bodies 24 is released, a space is formed at the bottom of the bag B, so that the dust D falls into the bottom of the bag B as shown in the operation diagram of FIG. As a result, even when the refuse D is forced into the bag B, the entire amount of the refuse D is stored in the bag B with a margin at the mouth of the bag B.

As shown in FIG. 7B, by forming the upper ends of the front and rear clamp bodies 24 so as to mesh with each other,
The bag B positioned at the head of the bag material A can be separated from the subsequent bag simply by being clamped by the front and rear clamp bodies 24.
Although the capacity regulating means and the separating means (for example, a cutter) may be provided separately, there is an advantage that the structure can be simplified if the clamping body 24 is also used as the separating means as in the embodiment.

When the bag B is filled with the refuse D, the bag B is fed by a feeding mechanism to a tape-type sealing machine provided on the left side of the main body 2.
It is transferred to 33 and sealed. This will be described below. Figure
As shown in FIG. 2 (A), FIG. 3 (B), and FIG. 8, in a portion below the front and rear upper shaft 13, a left and right longitudinal feed guide member 34 constituting a part of the feed mechanism is arranged. . The feed guide member 34 has a substantially L-shaped side cross section, and is arranged so that the horizontal pieces in the state face each other, and extends long in the left-right direction to a position close to the inner surface of the upper sprocket 15. .

At the left and right ends of the forward and backward feed guide member 34, legs 34a extending vertically in portions left and right outside the clamp body 24 are integrally formed.
Are rotatably fitted on the support shaft 25. And FIG.
As is clearly shown in the figure, horizontal portions 34b extending so as to overlap each other are formed at the lower ends of the left foot portions 34a of the front-rear feed guide member 34, and the front-rear horizontal portions 34b and the upper ends of the vertically interlocking third interlocking rods 35 are formed. And are connected by a pin 36. The pin hole of the front-rear horizontal portion 34b of the feed guide member 34 is formed as a long hole elongated in the horizontal direction.
When the 35 is pulled downward, the front-rear feed guide member 34 rotates inward so as to approach each other.

The lower end of the third interlocking rod 35 is connected by a pin to the tip of the second turning rod 37 to which the second foot pedal 6 is attached, so that a person steps on the second foot pedal 6 with a foot. Then, the front and rear feed guide members 34 are rotated so as to approach each other. With the second foot pedal 6 fully depressed,
A slight gap is left between the front and rear feed guide members 34.

It is preferable that a lock mechanism be provided so that the second rotating rod 37 is held in a downwardly rotated state even when the foot is released when the second foot pedal 6 is depressed. Alternatively, the setting may be such that when the second foot pedal 6 is depressed, the first turning rod 28 returns and turns to close the lid 3. The bag B into which the refuse D is put is sent to the sealing means by a pusher 38 which moves along the feed guide member 34 in a rotated state. The pusher 38 includes an upper plate 38a, a lower plate 38b, and a connecting portion 38c connecting the right and left ends of the upper plate 38a and the lower plate 38b.
It is formed in a U shape when viewed from the front. The pusher 38 is attached to a block 40 via an arm 39. The block 40 is slidably fitted to a pair of front and rear guide bars 41 mounted between left and right side plates of the main body 2. A screw shaft 42 rotatably mounted between the left and right side plates 2a of the main body 2 is screwed into the block 40.
Is driven by a second motor 43 attached to the right side plate 2a of FIG.

Therefore, when the second motor 43 is rotated forward and backward, the pusher 38 moves left and right. As clearly shown in FIG. 2 (B) and FIG. 8, with the feed guide member 34 being rotated inward,
The upper end of the feed guide member 34 is the upper and lower plates 38 of the pusher 38.
It is set to fit between a and 38b. As shown in FIG. 3 (A), the pusher 38 is located outside the upper right sprocket 15 when not in operation. And lid 3
Is closed, the second foot pedal 6 is depressed with the foot to rotate the feed guide member 34 inward, and then the button is pressed to drive the second motor 43.
Move towards. Then, the mouth of the bag B is pushed up and down by the upper plate 38a and the lower plate 38b of the pusher 38.
Is sent to the sealing machine 33 while its mouth is squeezed while peeling off from the feeding bar 20.

The sealing machine 33 is the same as the one widely used as a manual bag sealing machine in shops and the like.
As shown in the figure, the upper and lower frame plates with the guide grooves 45 cut open
The upper and lower frame plates 46 have cut-out holder portions 48 for loading rolls of adhesive tape 47. Also, on both sides of the guide groove 45 between the upper and lower frame plates 46,
Guide wheel 49 with a large number of recesses formed on the outer circumference, adhesive tape 47
And a rotary press member 50 for pressing the guide member 49 on the guide wheel 49, and a cutter 52 attached to the rotary body 51 is disposed between the upper and lower frame plates 46. The adhesive tape 47 is sandwiched between the guide wheel 49 and the pressing member 50 with the adhesive surface facing outward.

The holding member 50 is urged by a guide wheel 49 by a spring 53, and the cutter 52 is provided with a guide groove.
It is biased by a spring 55 in a direction to escape from 45. In addition, a protruding portion 45 a that crosses the guide groove 45 is formed in the rotating body 51. Further, a funnel-shaped guide portion 46a is provided on the upper and lower frame plates 46 so that the mouth portion of the bag B smoothly moves to the guide groove 45 from the gap between the front and rear feed guide members 34.

As shown in FIG. 6B, the upper plate 38a of the pusher 38 is located above the upper frame plate 46 of the sealing machine 33, and the lower plate 38b of the pusher 38 is positioned at the lower frame plate 46 of the sealing machine 33. , And even if the tip of the pusher 38 moves to a position beyond the protruding portion 51a of the rotating body 51 in the sealing machine 33, the connecting portion 38c of the pusher 38 is
It is set so as not to interfere with 49 and the holding member 50.

As shown in FIG. 6, the mouth of the bag B pushed and moved by the pusher 38 is squeezed, and the tape-type sealing machine 33 is inserted through the gap between the forward and backward feed guide members 34.
When the tape 47 is wound around the mouth of the bag B in the process of passing through the guide wheel 49, and the mouth of the bag B pushes the protrusion 51a of the rotating body 51, the rotating body 51 rotates and the tape 47 is cut by the cutter 52, and both ends of the adhesive tape piece 47 'wound around the mouth of the bag B are adhered to each other. This ends the sealing.

When the sealing is completed, the bag B containing the refuse D is discharged from the discharge port 7 shown in FIG. 1 by its own weight, and the discharged garbage bag B is placed in a basket or box placed at the discharge port 7. Etc. are collected in a collection container. Note that a support member for supporting the bag B in a state where it can be moved by the pusher 38 may be provided so that the bag B does not drop by the weight of the dust D after the clamping by the clamp body 24 is released.

In the present embodiment, the feeding and sealing of the bag material A are automatically performed by a motor, and the driving of the clamp body 24 and the rotation of the feed guide member 34 are performed by manual operation. The whole may be automatically performed by using a driving unit such as an electromagnetic solenoid or an electromagnetic solenoid, or the whole may be configured to be driven manually. Even if the bag B is provided with a sufficient storage capacity by the clamp body 24, the capacity of the bag B is limited, and the bag B cannot be sealed in a state where the refuse D overflows from the inlet 4. . Regarding this point, even if the bag B is full of the refuse D, it is set so that the bag B can be sealed if the cover 3 can be closed, while it is confirmed that the cover 3 is completely closed. Provide a limit switch or sensor to detect
It is preferable to make a connection so that the second motor 42 is not energized unless it is closed properly. This is preferable from the viewpoint of safety.

FIG. 10 shows a modification of the first embodiment. In this embodiment, when a tape-type sealing machine 33 as in the first embodiment is used as the sealing means,
The pusher 38 is configured as a scissor-shaped open / close type, while the sealing machine
Guide members 56 are provided on the upper and lower sides of 33 to narrow and rotate the pusher 38 when the mouth of the bag passes through the guide groove 45 of the sealing machine 33.

With such a configuration, the mouth of the bag B can be passed through the guide groove 45 of the sealing machine 33 while the mouth of the bag B is strongly grasped by the pusher 38, so that the adhesive tape 47 is used. This is an advantage that sealing can be more reliably performed. The mouth of the bag B may be twisted by the pusher 38. In the above-described first embodiment, a bag material having continuous bags is used. However, as shown in FIG. 11 (A), bags B separated one by one are stacked and one by one from the upper end. You may make it pay out. In addition, the side seal method using a hot plate is performed while simultaneously forming the bottom and cutting while feeding out a tubular film raw material, or while feeding out two (or one) strip-shaped film raw materials. May be sequentially formed.

The capacity regulating means is not limited to the clamp body of the first embodiment. For example, as shown in FIG. 11B, a regulating plate 57 for suppressing the bag from spreading laterally is provided. Embodiments The clamp body 24 of the first embodiment may be configured to be pushed upward. The sealing means is not limited to using the tape-type sealing machine as in the embodiment, and is sealed using a metal wire or sealed with a binding machine using a string, or mechanical or high-frequency. Various means such as sewing with a sewing machine such as a sewing machine can be adopted. If there is no adverse effect due to the temperature rise due to heating, welding may be performed using a hot plate, ultrasonic waves, or the like. In addition, a vacuum means for bleeding air from the bag may be provided before the sealing, which is advantageous in that the bag in which dust is stored can be prevented from being bulky.

As the bag, various materials and shapes can be used as required, such as a paper bag, a laminate of paper and a synthetic resin, or a net bag. Further, the means for holding the bag in the opened state is not limited to the delivery bar with the adhesive as in the first embodiment, and the mouth of the bag is grasped by mechanical means (for example, an electromagnetic solenoid or a spring). Or it may be held using a vacuum.
