However, the above-mentioned prior art has the following problems. That is, JP-A-2000-79349 and JP-A-10-2
30184 has a structure in which an endless conveyor having a plurality of claws arranged along a moving portion is provided, so that the length of the device is increased, the device is increased in size, and the device cost is increased. In addition, when the bag containing the bottle is hung on the claw and goes up the slope of the endless conveyor, the bag comes off the claw and falls below the endless conveyor, and the internal bin is broken, making recovery impossible. See the occurrence of

In the prior art, a bag containing a bottle is transported along a long endless conveyor to an upper end of the conveyor, and is stopped by a dam plate provided corresponding to the upper end. Since the bottles are broken and the bins are dropped, the noise is large due to the collision noise between the bins and the collision noise when the bins fall while colliding with the surface of the conveyor or the claws. Furthermore, since the long endless conveyor extends obliquely upward, it is necessary to adjust the tension of the conveyor at any time, and it takes time and effort to clean the conveyor, and the maintainability is not good.
And the like.

Further, in the invention of Japanese Patent Application Laid-Open No. 10-5614, a bottle is inserted by a reverse V-shaped blade and a heater attached to the outer periphery of the rotor along the circumferential direction according to the rotation of one rotor. Since the bag is melted and broken, the bag attached to the blade is removed by rubbing it with the groove edge of the baffle plate. However, there is a problem that the bag and the bottle are not sufficiently separated from each other even if the melting action is added, and the debris of the bag adheres to the bottle side, so that the bottle is not sufficiently recovered.

SUMMARY OF THE INVENTION In view of the problems of the prior art, the present invention has a compact and compact apparatus structure and eliminates the need for a special bag melting means such as a heater, thereby efficiently separating a waste container such as a bottle from a bag. It is an object of the present invention to provide a bag breaking / bag removing device which can be performed reliably, has reduced noise, and has improved maintainability.

[0010]

In order to solve the above-mentioned problems, the present invention breaks a bag such as a plastic bag containing a waste container such as a used bottle or a plastic bottle,
In a bag breaking and bag removing device configured to separate and remove the bag from the waste container, a plurality of bag breaking blades that are rotated in opposite directions to break the bag are attached along the outer periphery. Two rotors are disposed with a gap in which the closest position between the two rotor peripheral surfaces is smaller than the outer diameter of the container, and the rotation directions of the two rotors are set so that the rotor outer peripheral surfaces are separated from the closest position. While forming upwards,
A container movement preventing member that separates the waste container and the bag body at a position higher than the axis of the outer peripheral surfaces of the rotors and returns the waste container to the closest position between the rotor peripheral surfaces. The present invention proposes a bag breaking and bag removing apparatus characterized by being provided with: In this case, it is preferable that the two rotors are arranged so that their rotation axes are parallel to each other.

According to a third aspect of the present invention, in the case where the waste container is a bottle, a gap between the top of the tooth tip and the container movement preventing member is formed to be smaller than a radius of the container opening. Are arranged at predetermined intervals along the axial direction in each of the rotors, and preferably, the gap between the top of the bag-breaking blade tip and the container movement preventing member is smaller than the radius of the bottle mouth. It is characterized by having been formed. Further, the gap between the outer peripheral surfaces of the rotors and the container movement preventing member is preferably formed to be smaller than the diameter of the bottle.

Further, it is preferable that a cushioning material for alleviating collision with the waste container is attached or applied to a portion of the outer peripheral surfaces of the rotors between the bag-breaking blades.

Preferably, the two rotors are installed such that their rotation axes are inclined in one direction at a predetermined inclination angle, and more specifically, an inclination for adjusting the inclination angles of the two rotor axes. It is characterized by having an angle adjusting device.

Further, according to the present invention, a container discharge control member is arranged at the outlet side in the rotor axis direction of the container moving space sandwiched between the rotors so as to be swingable in the rotor axis direction. The present invention is characterized in that a restraining means for restraining the bag breaking container from expanding by pressing is provided. Specifically, the discharge regulating member is a plate-shaped member having a swing fulcrum that can swing in the rotor axis direction on the upper end side, and a weight is provided below the plate-shaped member, (the upper end is the rotor shaft). (Because the swing shaft is orthogonal to
It is preferable to function as suppression means for suppressing expansion of the unbroken bag container by pressing.

Further, air is blown in a forward direction along the rotation direction of the two rotors to the downstream side of the rotor from the container movement preventing member provided above the outer peripheral surfaces of the two rotors, so that the air from the bag-breaking blades of the bag body is reduced. It is preferable to provide an air blowing means for performing separation.

According to this invention, the bag containing the waste container including the bottle supplied in the moving space formed between the pair of rotors rotated in opposite directions is rotated by the rotation of each rotor. While moving to both outer sides in the rotation direction, the rotation of both rotors is utilized by the vertical blades of the plurality of bag-breaking blades attached to the outer periphery of the rotor, and the bag body is preferably operated by the leaf spring action of the bag-breaking blade. Along with cutting the bag circumferentially to break the bag, the lateral blade of the bag breaking blade and the container movement preventing member cooperate to separate the waste container including the bottle by the bag breaking by the bag breaking blade, and the both rotors are separated from each other. The bag body moved to the gap with the container movement preventing member can be chopped so as to be able to pass through the gap, and the gap is formed to be smaller than the diameter of the bottle of the waste container. Clearance of waste container The emission is sandwiched is avoided.

Therefore, according to the invention, the bag containing the waste container containing the bottle therein can be reliably broken by separating the waste container by cooperation of the bag breaking blade and the container movement preventing member. In addition, the bag from which the waste container has been separated can be reliably discharged to the outside through the gap between the rotors and the container movement preventing member.

According to this invention, the bag containing the waste container supplied in the moving space formed between the pair of rotors rotated in opposite directions is rotated by the rotation of each rotor. While moving to both outer sides in the direction, the plurality of bag-breaking blades attached to the outer periphery of the rotor and the container movement preventing member cooperate to break the bag using the rotation of both rotors, and to separate the waste container after separation. Since the bag is configured to remove the bag, the waste container can be smoothly moved in the moving space in the axial direction of the rotor, and the waste container does not drop unlike the related art, and the containers collide with each other. Noise due to noise and the like is suppressed, and low-noise operation can be realized. Furthermore, no special adjustment or maintenance is required other than wear of the bag-breaking blade, and the maintenance of the device is easier and easier to maintain than the conventional technology that adjusts the tension of a long endless conveyor. improves.

Further, at the time of the bag breaking and bag removing operations, the pair of rotors are inclined so that the outlet side of the waste container is downward in the longitudinal direction.
The bag is moved to the lower side of both rotors while the bag is broken in the moving space, and the waste container after separating the bag is taken out from the gap below the unbroken container discharge control member. Thereby, the waste container after the bag body is separated can be smoothly moved to the lower part of the rotor along the surfaces of the two rotors inclined as described above. Further, by adjusting the inclination angle of the rotor by the inclination angle adjusting device, the moving speed of the waste container to the lower part can be adjusted.

Further, since a cushioning material is attached to the outer peripheral surfaces of the pair of rotors, the collision between the bin of the waste container and the surface of the rotor is reduced by the buffering action of the cushioning material. The generation of cracks is avoided, and the surface of the cushioning material is easily slipped, so that the bag is prevented from adhering to the surface and smooth discharge is achieved.

Further, the unbroken bag container discharge control member prevents the unbroken bag in which the container is still sealed or the bag separated from the waste container from being discharged to the rotor side. The unbroken bag container can be discharged to the outside from a passage below the discharge control member.

Furthermore, the bag ejected from the waste container in the gap between the outer peripheral surface of the rotor and the container movement preventing member by the air blowing means does not remain on the peripheral surface of the rotor until the next crushing operation. Thus, the air can be reliably discharged to the outside of the gap.

As shown in FIGS. 4 and 5, the bag body 11 containing the bottle 10 is hooked on the vertical blade 41 of the bag-breaking blade 4, and is moved in the rotation direction N by the rotation of the rotors 1a and 1b. 4A, the cutting edge of the vertical blade 41 bites into the bag body 11 in the circumferential direction, and the hole is torn, and the hole is torn in the circumferential direction.

At this time, the bag-breaking blade 4 is formed in a cantilever leaf spring shape in which the root of the support plate 43 is fixed to the outer peripheral surfaces of the rotors 1a and 1b by bolts 12 (see FIG. 4). FIG.
The bag-breaking blade 4 bent in the direction of arrow B in FIG. 4A is warped upward by the spring force of the support plate portion 43 as shown by arrow D in FIG. When the edge of the vertical blade 41 bites into the bag 11, the bag 11
Is torn and the internal bin 10 jumps out upward.

When the bag 11 comes into the gap 13 of the container movement preventing member 5 as described above, the horizontal blade 42
A plurality of blades cuts the bag 11 from which the bottle 10 is separated in cooperation with the lower edge of the container movement preventing member 5, and the bag 11 is discharged to the outside through the gap 13. .

During the bag breaking and bag removing operations of the bag 11, a pair of rotors 1 rotated in opposite directions to each other.
The bag body 11 supplied into the moving space 14 formed between a and 1b is attached to the outer periphery of the rotors 1a and 1b while being moved outward in the rotation direction by the rotation of the rotors 1a and 1b. The longitudinal blades 41 of the plurality of bag-breaking blades 4 utilize the rotation of the rotors 1a and 1b, and the bag body 11 of the bag-breaking blade 4 is circumferentially torn by the leaf spring action of the support plate 43 to break the bag. In addition, the horizontal blade 4 of the bag breaking blade 4
2 and the container movement preventing member 5 cooperate with each other,

Guided to the side.

During the bag breaking operation of the bag body 11, the rotors 1a and 1b have their rotation axes 7a and 7b inclined at an angle α (= about 5 ° to 10 °) with respect to a horizontal line.
Thus, since the outlet side of the bottle 10 after separating the bag body 11 in the longitudinal direction is inclined downward, the bag body 11 is broken in the moving space 14 while the lower part of the rotors 1a and 1b is broken. After the bag 10 is moved to the side and the bag body 11 is separated, the unbroken bag container discharge control plate 8 is taken out to the outside from the expanded space below while swinging against the pressing force. Thereby, the bin 10 after the bag 11 is separated is smoothly moved to the lower part of the rotors 1a and 1b along the inclined surfaces of the rotors 1a and 1b as described above. Further, by adjusting the tilt angle α of the rotors 1a and 1b by the tilt angle adjusting device 50, the moving speed of the bin 10 to the lower portion can be adjusted.

Since the outer package 7 is attached to the outer peripheral surface of each of the rotors 1a and 1b, the collision between the bin 10 and the surfaces of the rotors 1a and 1b is reduced by the buffering action of the outer package 7. In addition, the occurrence of cracks in the bottle 10 due to the collision is avoided, and the surface of the exterior material 7 is easily slid, so that the bag 11 is prevented from adhering to the surface, and smooth discharge is performed. You. The bag 11 from which the bin 10 is separated is guided to the downstream side in the rotation direction of the rotors 1a and 1b through a gap 13 between the rotors 1a and 1b and the container movement preventing member 5, and the bag 11 is provided with an air nozzle. 5
1 by the air jet 52 from the rotor 1
The tear-off bag body 11 in which the jet flow is formed in the tangential direction of the outer peripheral surfaces of the a and 1b and tightly adhered to the bag-breaking blade 5 is reliably left outside by the pneumatic force without remaining on the rotors 1a and 1b. Can be discharged.

Further, the unbroken bag container discharge control plate 8
The unbroken bag or separation bag 11 in which the bottle 10 is sealed is prevented from being discharged from the moving space onto the rotors 1a and 1b,
Only the bin 10 can be discharged to the outside from the passage below the unbroken container discharge control plate 8.

By cooperating with the container movement preventing member, the bag containing the waste container including the bottle therein can be reliably broken to separate the waste container, and the separated bag can be separated into the two rotors and the container. It can be reliably discharged to the outside through the gap with the movement preventing member. Further, since the gap is formed smaller than the diameter of the bin of the waste container, the bin of the waste container is prevented from being caught in the gap, and the waste container is smoothly discharged.

Further, according to the present invention, in a moving space formed between a pair of rotors rotated in opposite directions to each other, the bag is broken by utilizing the rotation of both rotors,

In addition, noise due to collision noise and the like is suppressed, and low-noise driving can be realized. Furthermore, no special adjustment or maintenance is required other than wear of the bag-breaking blade, and the maintenance of the device is easier and easier to maintain than the conventional technology that adjusts the tension of a long endless conveyor. improves.

Further, at the time of the bag breaking and bag removing operations, the pair of rotors are inclined so that the outlet side of the waste container is downward in the longitudinal direction.
The bag is moved to the lower side of both rotors while the bag is broken in the moving space, and the waste container after separating the bag is taken out from the gap below the unbreakable container discharge control member. Accordingly, the waste container after the bag is separated can be smoothly moved to the lower part of the rotor along the inclined surfaces of both rotors. Further, by adjusting the inclination angle of the rotor by the inclination angle adjusting device, the moving speed of the waste container to the lower part can be adjusted.

Further, since a cushioning material is attached to the outer peripheral surfaces of the pair of rotors, the collision between the bin of the waste container and the surface of the rotor is reduced by the buffering action of the cushioning material, and the bottle due to the collision is reduced. The generation of cracks is avoided, and the surface of the cushioning material is easily slipped, so that the bag is prevented from adhering to the surface and smooth discharge is achieved.

Further, the unbroken container discharge control member prevents the bag separated from the waste container from being discharged to the rotor side, so that only the waste container is discharged from the passage below the unbroken container discharge control member. Can be exhausted.

Further, the bag body separated from the waste container in the gap between the outer peripheral surface of the rotor and the container movement preventing member by the air blowing means does not remain on the peripheral surface of the rotor until the next crushing operation. Thus, the air can be reliably discharged to the outside of the gap.
