DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of sorting and discarding non-burnable refuse wrappings from households in flammable bags in municipalities.
The present invention relates to a bag breaking device used for performing the processing.

[0002]

2. Description of the Related Art In local governments, from the viewpoint of difficulty in disposing of garbage and resource saving, etc., garbage for households and the like is discarded by distinguishing the garbage by burning and non-burnable garbage. With regard to the collected non-burnable garbage, measures have been taken to select and collect recyclable garbage such as metal and empty bottles. As this means, a recycle waste sorting apparatus is used, in which a bag breaking device for recyclable waste packages is incorporated as a device prior to the sorting.

[0003] Since the recyclable garbage package is wrapped in a plastic bag, a paper bag, or the like, a conventional bag breaking device of this kind breaks the bag to release the garbage, so that a rotary is placed at the outlet of the hopper. And a movable plate that is urged by a spring and opposed to the movable plate is provided in Japanese Utility Model Publication No. 60-285.
No. 06 discloses a rotary assembly in which a plurality of blades are radially protruded from a rotary shaft so as to unload a recycle refuse package inserted at an outlet of a hopper. It is.

[0004]

According to the above-described conventional bag-breaking apparatus for recyclable garbage packages, it is difficult to feed the recyclable garbage packs by the rotary, and the rotary garbage pack is rotated with respect to the recyclable garbage packs. The blades and the movable plate act strongly, the bags of the resource garbage package are torn, and the garbage is released. However, sometimes the bags were discharged unprocessed without tearing.

[0005] As a result of studying the cause, the adjacent blades radially provided in the rotary have a V-groove shape, and the package is sent downward when the package fits in the V-groove. Therefore, although it depends on the size of the bag, most of the bags handled in ordinary households are about 1 m square or less. Therefore, the conventional apparatus is formed so as to accommodate a package of that size. However, in practice, bags with a size smaller than the above-mentioned bags are also mixed, and the disadvantage of small packages is that they fall on the conveyor without being broken without touching the movable plate. there were.

Therefore, in order to reliably break even small packages, the diameter of the rotary may be reduced and the opening width of the V-groove may be reduced, but it is difficult to feed a large package. There was a problem.

According to the present invention, in view of the above-mentioned circumstances, not only is it possible to reliably perform bag-breaking processing even if large and small items are mixed in the recyclable garbage package, but also to obtain uniformity in the bag-breaking processing amount at all times. An object of the present invention is to provide a bag breaking device for recyclable waste packages.

[0008]

According to the present invention, there is provided a bag-breaking device for recyclable garbage packages, which is provided at an outlet of the hopper, and has a rotating shaft. A bag-breaking chamber having a rotary having a plurality of blades protruding radially and at equal intervals, a movable plate facing the rotary and biased toward the rotary, and provided below the bag-breaking chamber. Each blade is provided over the entire width of the rotary in the axial direction, and a flat support plate extending across the entire width of the rotary in the axial direction between adjacent blades is packed in a rotary in a garbage package. The main part of the body fits, but a part of it protrudes, and each support plate has a polygonal shape. Characterized by .

[0009]

[Effects] Even if large and small packages are mixed in the recycle refuse package put into the hopper, the distance between the adjacent blades is large and the depth is small, so that even small and large packages can be used. A fixed amount can be conveyed, during which it is pressed by the movable plate and broken by its blade.

[0010]

Next, this embodiment will be described with reference to the drawings.

The drawing shows an example implemented as a device at a stage prior to the sorting in the resource garbage sorting device. The bag breaking device for the resource garbage package is the same as the above-mentioned conventional example of the present applicant. A hopper 3 that is a rotary revolving type developed and that puts a resource refuse package S into a machine frame 1.
A bag-breaking chamber 5 having an outlet 4 opened, and a conveyor 7 facing the opening of the bag-breaking chamber 5 in order from the top, and a rotary 8 having a bag-breaking function is provided in the bag-breaking chamber 5. , And a large number of movable plates 9. The entire structure is horizontally long so that the recyclable garbage packages S can be simultaneously processed in large quantities.

The hopper 3 is provided with a front inclined wall 11 near the outlet 4 so as to prevent stagnation of the recyclable garbage package S.
Is formed to be steeper than the rear inclined wall 13, and the lower end of the front inclined wall 11 is protruded long toward the bag breaking chamber 5. In other words, in this case, due to the relationship with the rotary 8, the recyclable refuse package S is easily moved from back to front and then downward (see the arrow in FIG. 4).

For mounting the movable plate 9, the front inclined wall 11
The bag-breaking chamber 5 is opened forward below. Also,
The bag-breaking chamber 5 has a rear wall 15 formed in a rearward bent shape at the rear. By providing the rotary 8 close to the rear wall 15, the drop 4 of the recycle refuse package S is located between the lower end of the front inclined wall 11 of the hopper 3 and the rotary 8.
a can be opened. However, the falling port 4a is incompletely sealed by the movable plate 9 in an openable and closable state.

The rotary 8 is assembled around a rotating shaft 17 driven by a motor.
Are fixed to both ends of each of the intermediate flanges 19, 19, and some intermediate flanges 21 also formed in a circular shape therebetween.
Are fixed at equal intervals.
1 and between the intermediate flange 21 and the intermediate flange 21
And four blades 2 each
3 project in the radial direction. In addition, each of the blades 23, 23
The plate-like support plates 25 are interposed between the blades 2, and the blades 2 adjacent to each other with the surface facing the outer periphery of the rotary 8.
Each support plate 25 is provided so as to form a polygonal shape including a quadrangle at a distance from the rotation base shaft 17 between the base plates 3 and 23.
The depth at which the supporting plate 25 is erected is set to a depth at which most of the recyclable garbage can be accommodated in the rotary 8 but part of the refuse wrapping protrudes. Even the largest package is preferably sent out by the rotary 8, and even a small package smaller than that is held on the surface layer of the rotary 8 by the support plate 25 and pressed by the movable plate 9 during rotation. obtain. The support plate 25 may be provided along the circumference at equal intervals from the rotating base shaft 17 in accordance with the contents of the recycle refuse package S. Thereby,
A shaft having a large diameter is formed as a whole from the appearance. Each member is assembled by welding.

A large number of bag-breaking blades 27, 29 are respectively mounted on the intermediate flange 21 and the blade plate 23 so as to be replaceable by bolting (not shown). Regarding the arrangement, in the case of the intermediate flange 21, the blades are attached at equal intervals in a state where the cutting edge protrudes from the outer peripheral edge, and
In the case of the blade 23, the blades are arranged at equal intervals at the tip end and the cutting edge is protruded from the edge. The angle of attack is such that the resource refuse package S can be scratched.

A number of movable plates 9 are arranged continuously along the longitudinal direction of the apparatus, and each is provided as an independent body so as to operate properly according to local circumstances. For the equipment, the front inclined wall 11 of the hopper 3
The outer periphery of the lower end is pivotally supported by a pin 30 and urged by a spring 31 in a direction to close the dropout 4a. For the biasing, a support rod 33 is pivotally supported on the horizontal member 2 of the machine frame 1 so as to be able to swing up and down, and a slider 35 and a spring 31 pressing the slider are fitted on the support rod 33, and the slider 35 is moved by a movable plate. 9 is pin-connected.

A large number of bag-breaking blades 37 are mounted on the movable plate 9 in a replaceable manner by bolts. The arrangement is such that two rows are provided on the upper surface for receiving the recycle refuse package S, that is, the front end portion and a position closer to the base end portion than the front end portion.

[0018]

As described above, according to the present invention,
In the rotary, the amount of recyclable garbage package that fits between adjacent blades is evenly broken, and the support plate is
Most of the recyclable garbage can be accommodated in the rotary, but a part of the package can be protruded. Fits within the radius of rotation of the rotary and is sent out favorably, conversely, even with a relatively small package, it is held on the surface layer of the rotary by the support plate,
During the rotation, it is pressed by the movable plate, and the bag is reliably broken in both large and small cases.

Since the bag-breaking blade is provided not only on the movable plate but also on the rotary, the package in the hopper can be broken even during the rotation of the rotary.

Further, as a result of erection of the flat support plate, the depth from the outer periphery of the rotary to the support plate becomes shallower at a portion closer to the blade plate. When the body is broken, the action of sending out the recyclable garbage package while pressing it against the movable plate with the rotation of the rotary is achieved, which is particularly effective.
