2. Description of the Related Art For example, a glass bottle to be recycled as a recycled raw material and a garbage bag containing a metal can are crushed and then broken pieces that hinder the reproduction are removed.
Glass bottles and metal cans are sent to the recycling process. Initially, the above-mentioned garbage bags were torn open manually by one bag, but there is a problem in the work environment and safety and hygiene such as bad odors and cuts on fingers, so automation of the bag-breaking work is done. , Mechanization has begun.

As a measure for mechanization, the actual Kaihei 3
An example of a bag breaking device is disclosed in the "bag breaking device for garbage bags" according to Japanese Patent No. 81808. In the following, this bag breaking device will be described by using the reference numerals of the above publications in the last two digits as they are in FIGS. FIG. 19 is a vertical sectional front view of the bag breaking device 100, FIG. 20 is a plan view of the same, and FIGS. 21 and 22 are schematic diagrams of operating states of essential parts.

To explain the bag breaking device 100, a chain conveyor 101 is attached to a machine body 114, and a chain transmission mechanism 107 is provided between a main shaft 102 of the chain conveyor 101 and a motor 106 attached to the machine body 114. The chain conveyor 101 is driven to rotate. A dust bag feeding body 104 formed of obtuse triangular plate bodies is provided so as to project in two rows over the entire width of the apron pan 103 of the chain 101, and the dust bag A is broken on the ridge line behind it. A cutting blade 105 for forming is formed (FIG. 21). Further, the group of dust bag feeding bodies 104 are arranged at intervals over the entire length of the chain conveyor 101.

A breaking device 108 is attached to a machine frame 115 which is erected on the machine body 114, and the two rows of dust bag feeding bodies 10 mounted on the chain conveyor 101 described above.
3 are arranged in a staggered manner with respect to No. 4 and are further arranged in three stages in the longitudinal direction at intervals corresponding to the interval in the longitudinal direction of the dust bag feeding bodies 104. Each breaking device 108 has an air cylinder 109 at its upper end, and its piston rod 1
A lower end of 10 and one end of a support arm 111 whose other end is pivotally attached to the machine frame 115 are pivotally attached, and a bag breaking blade 112 is attached to the support arm 111. The bag-breaking blade 112 is made of an obtuse triangular plate having a cutting edge 113 formed on the front ridge so that the dust bag A can be broken (FIG. 21), and is constantly pressed by the pressing force of the air cylinder 109. Was urged by
The support arm 111 is attached so as to be vertically rotatable.

A gate 116 is erected on the machine body 114 in front of the breaking device 108 and can be adjusted within a range of 250 mm to 400 mm from the upper surface of the apron pan 103 of the chain conveyor 101 by an operation handle 117 attached to the upper end. It is mounted so as to move up and down and limits the height of the dust bag A transferred to the breaking device 108. Further, a carry-in plate 118 is attached to the machine body 114 on the upper surface of the carry-in entrance of the chain conveyor 101.

Regarding the operation of the bag breaking device 100, the dust bag A loaded from the carry-in plate 118 drops on the apron pan 103 of the chain conveyor 101, is locked by the dust bag feeding body 104, and is gated by the gate 116. The height is checked and sent to the breaking device 108.

Referring to FIG. 21A, the dust bag A sent to the breaking device 108 is pushed by the dust bag feeding body 104 and compressed between it and the bag breaking blade 112, and the compression force is broken. When the pressing force initially set on the air cylinder 109 of the device 108 becomes larger than, for example, 8 kg / cm ² , the piston rod 110 of the air cylinder 109 is compressed via the bag breaking blade 112, and the support arm 111 is rotated. The bag-breaking blade 112 is pushed upward as shown in FIG. 21B. When the compression force is smaller than the initially set pressing force, the bag breaking blade 112 is not pushed up, and the dust bag A is pushed by the dust bag feeding body 104 and further transferred.

As a result, as shown in FIG. 22A, the dust bag A is pressed by the staggered meshing between the dust bag feed body 104 and the bag-breaking blade body 112 which is always under pressure. However, since the dust bag feeding body 104 and the bag breaking blade 112 are obtuse triangular plate bodies respectively, the dust bag A and the cutting blade 105 and the cutting blade 1 are arranged so as to get over them.
When it slides while being pressed on 13, it is cut open and ruptured. Then, the broken bag A is put on the apron pan 103 in a state of being locked by the garbage bag feeding body 104 as shown in FIG.
It is said that it is transferred to the discharge end of No. 01 and sent to the next step such as sorting work.

However, the bag breaking device 100 has the following drawbacks. The bag-breaking device 100 breaks the waste bag A with the dust-bag feeding body 104 having the cutting blade 105 and the bag-breaking blade 112 of the bag-breaking device 108.
One of the garbage bag feeding bodies 104 is the chain conveyor 10
Since they are arranged over the entire length of 1, the plurality of dust bag feeding bodies 104 are required although they are arranged at intervals. Therefore, the entire weight of the chain conveyor 101 becomes large, and the power required to drive the rotation of the chain conveyor 101 is excessive. Also,
Producing a large number of dust bag feeding bodies 104 in which the cutting blades 105 are formed and disposing them integrally with the entire length of the chain conveyor 101 significantly increase the production cost.

Further, the size of the dust bag A sent to the breaking device 108 is limited by the gate 116 provided on the chain conveyor 101, but if the large dust bag A is left as it is, the gate 116 becomes clogged, The dust bag A is no longer conveyed to the breaking device 108.

Furthermore, the breaking device 108 includes the cutting blade 10.
Since it functions as the bag breaking device 100 for the garbage bag A only when it is combined with the chain conveyor 101 in which the garbage bag feeding body 104 having 5 is disposed, if this bag breaking device 100 is adopted, resource garbage selection in each city Belt conveyors for bag breaking that the processing plant already owns must be discarded.

The first hanging type bag breaking machine 11 is constructed as described above, and its operation will be described below. Referring to FIGS. 1 and 2, a dust bag W containing a glass bottle G and a metal can C, which is mainly made of a plastic film, is thrown in through an inlet 7 and drops through a chute 8 onto a belt 31 which goes up on a belt conveyor 30. . The ascending belt 31 is pulled by the drive roller 33 and, at the same time, a tension adjusting device 39
Since the driven roller 35 is controlled so as to have a predetermined tension by, it is always tensioned. Furthermore, a slight gap is left on the lower surface of the ascending belt 31 so that the frame 5
Since the support plate 6 is provided on a, the ascending belt 31 does not hang downward even when pressed from above.

The dust bag W is transported by being locked by the locking member 32 on the belt 31 and reaches the suspension type bag breaking machine 11, 12, 13. The dust bag W is a hanging type bag breaking machine 11, 12, 13

It is discharged from the discharge port 9. The flow of the entire bag breaking is as described above, and the operation of this bag breaking will be described in detail below.
In addition, the suspension type bag breaking machine 11, 12, 13, 21, 22, 2
Since 3 operates in exactly the same manner, the operation of the hanging type bag breaking machine 11 will be described.

FIG. 1 and FIGS. 11 and 1 showing the action of the bag breaking.
1 is a sectional view taken along line [12]-[12] of FIG.
2, the waste bag W that has been conveyed while being locked by the locking member 32 on the ascending belt 31 travels in the same direction as the transport direction of the hanging-type bag breaking machine 11 traveling blades 87, 87. It is bitten under the suspension type bag breaking machine 11 by ', and is also pushed by the locking member 32. Piston rods 43, 44 of air cylinders 41, 42 suspending the suspension type bag breaking machine 11
Is in a state of being pushed out with a predetermined pressure, so the dust bag W
Is sent to the downstream side while being nipped by a predetermined pressure between the bottom surface of the suspension-type bag breaking machine 11 and the ascending belt 31. 12
As can be seen in FIG.
Since 7, 87 'exist, the dust bag W is crushed by being sandwiched between the fixed 67 and the traveling blades 87, 87', and the crushed bag piece F is crushed.
And the contents, such as the glass bottle G, the metal can C, and the like, are separately mixed and sent to the downstream side.

When a large garbage bag W'has been conveyed,
In addition to the large bite force by the running blades 87, 87 ',
The pushing force by the locking member 32 also becomes large, and a force that pushes this up to the upstream end portion of the suspension-type bag breaking machine 11 acts. Therefore, when the force becomes larger than the predetermined pressing force of the air cylinders 41 and 42, As shown in A of 13, the piston rod 4
3, 44 are pushed in, and the first suspension type bag breaking machine 11 is lifted up more than the fourth suspension type bag breaking machine 21 in the normal height position. In this state, the large dust bag W ′ is squeezed by the traveling blades 87, 87 ′ and the fixed blade 67 while being pressed and clamped between the bottom surface of the suspension-type bag breaking machine 11 and the ascending belt 31 and conveyed. Will be sacked. When the large garbage bag W ′ is broken, the suspension-type bag breaking machine 11 descends to its original position.

When the trash bag W "which is not to be crushed is conveyed, as shown in FIG. 13B, the first suspended-type crushing machine 11 is lifted as a whole and large trash which is not crushed. The bag W ″ is conveyed by the traveling blades 87, 87 ′ and the ascending belt 31 and passes between the suspension type bag breaking machine 11 and the ascending belt 31. Similarly, in the fourth hanging-type bag breaking machine 21, a large garbage bag W ″ that is not broken is passed through. Therefore, a hanging bag breaking machine is used due to the large garbage bag W ″ that is not broken and coarse solid waste that is contaminated. No clogging of 11, 21 will occur.

The hanging type bag breaking machine 11, 12, 13, 2
Since the chains 1, 22, and 23 are driven independently of each other, the traveling speed of each chain may be changed depending on the size of the dust bag W to be conveyed, foreign matters, and other conditions. Depending on the vehicle, the traveling direction can be changed.

As a modified example of the suspension type bag breaking machine 11, as shown in FIGS. 14A and 14B, the suspension type bag breaking machine 1 in which the precession preventing rod 45 between the piston rod 43 and the air cylinder 42 is removed.
It can be 1 '. The same applies to the hanging-type bag breaking machine 21 'on the downstream side. By removing the steady rest rod 45 of the piston rod 43 of the one air cylinder 41 in this manner, it becomes possible to alternately move the upstream end and the downstream end of the suspension type bag breaking machine 11 'up and down. .

For example, as shown in FIG. 14A, when a large dust bag W'is conveyed, the running blades 87, 87 'increase the biting force and the pushing force by the locking member 32. May increase, a force that pushes up the suspension type bag breaking machine 11 ′ acts on the upstream end of the hanging type bag breaking machine 11 ′, and when the pushing force becomes larger than the predetermined pressing force of the air cylinder 41 on the upstream side, the piston rod 43 is When pushed in, the suspension-type bag breaking machine 11 'lifts the upstream end to eat in the large dust bag W'. Next, while continuing to press with a predetermined pressure, the large dust bag W ′ is crushed by the fixed blade 67 and the traveling blade 87 to be separated. In the case of a dust bag W of a normal size, the force that pushes up the upstream end of the suspension type bag breaking machine 11 ′ does not push the piston rod 43 of the air cylinder 41, so No tilt occurs,
The dust bag W is squeezed while being pressed and pinched and conveyed.

Further, when a large dust bag W "which is not broken by the bag breaking machine 11 'or a large solid dust which is contaminated in the dust bag W is conveyed as shown in A of FIG. As described above, when the piston rod 43 of the air cylinder 41 on the upstream side is pushed in, the suspension type bag breaking machine 11 'first takes a posture in which the upstream end thereof is lifted, so that, for example, a large dust bag W "that is not broken is moved up. It feeds to the downstream side by the running blade 87 and the ascending belt 31 while being caught between the belt 31 and being pressed and pinched. Large garbage bag W that is not broken
The piston rod 44 of the air cylinder 42 on the downstream side is gradually pushed in and the piston rod 43 on the upstream side is pushed out along with the movement of. Large garbage bag W that is not broken
14 is in the vicinity of the air cylinder 42 as shown in FIG. 14B, the piston rod 44 is pushed in, the upstream piston rod 43 returns to its original position, and the suspended bag breaking machine 1
1 ′ has a posture in which the downstream end is lifted. Therefore, even if there is a small trash bag W following the large trash bag W "that is not crushed, this will be ruptured at the upstream end, and no passing through of the trash bag W will occur. Since it is sent out from the downstream end of the suspension type bag breaking machine 11 'and passes through as it is, the hanging type bag breaking machine 11' is not clogged by the large dust bag W "which is not broken. Large garbage bag W ”that has not passed through the bag breaking machine 11 '
Similarly, the suspended type bag breaking machine 21 'also passes through and is discharged from the discharge port 19, so that it will be removed in a later step.

(Second Embodiment) FIG. 15 is a cutaway side view of a bag breaking device 2 in which a hanging bag breaking machine is combined with an inclined chute. The suspension type bag breaking machine 14 is arranged such that the bottom surface thereof is parallel to the transfer surface of the inclined chute 28 which is inclined downward toward the downstream side. Except for this point, the suspension type bag breaking machine 11 of the first embodiment is constructed in exactly the same manner. Therefore, corresponding elements are designated by the same reference numerals and their description is omitted.

As shown in FIG. 16, a hanging type bag breaking machine 15
Is different from the suspension type bag breaking machine 11 of the first embodiment in that a drive motor 79 'and a speed reducer 78' as well as a drive motor 79 and a speed reducer 78 are provided in the box body 60. FIG. 17
One of the drive motors 79 is connected to the sprocket 7 as shown in FIG.
Only 1 is driven and the sprocket 71 'is not driven. Therefore, the chain 81 and the driven sprocket 72 connected to the chain 81
But not the chain 81 '. Then, the other drive motor 79 'drives the sprocket 72' to rotate the chain 81 'wound around it and the sprocket 71' connected to it. Furthermore, the chains 81, 81 ', and thus the running blades 87
And 87 'can be run in opposite directions, or can be run at different speeds in the same direction. Further, the hanging type bag breaking machine 15 of the third embodiment does not have the fixed blade 67 on the bottom surface. Except for the above two points, the structure is exactly the same as that of the suspension type bag breaking machine 11 in the first embodiment, and therefore, corresponding elements are designated by the same reference numerals and their description is omitted.

In FIG. 16, for example, the dust bag W conveyed from the right side by the belt conveyor is pressed and sandwiched between the bottom surface of the suspension type bag breaking machine 15 and the belt conveyor. And 87 'are traveling in opposite directions, the dust bag W is torn as if it is sandwiched between the two, and the bag is broken without the need for a fixed blade. Even when the traveling blades 87, 87 'are traveling at different speeds in the same direction, the dust bag W is sandwiched between the traveling blades 87, 87' and broken.

When the traveling blades 87, 87 'are driven in the opposite direction at the same speed, the speed at which the dust bag W is pinched is higher than that when one of them is a fixed blade, and therefore the bag breaking speed is high. Besides, there is no direction for feeding the garbage bag W. For example, when the bag breakage is incomplete, the waste bag W is fed back to the waste bag carrier before the waste bag W reaches the discharge end.
To the suspension type bag breaking machine 15 in the opposite direction to carry out the second bag breaking, and then to make the garbage bag carrying device go forward again to carry out the third bag breaking to ensure the bag breaking. Operation is also possible.

(Fourth Embodiment) FIG. 18 is a partially cutaway side view of a suspension type bag breaking machine 16 as a fourth embodiment, and corresponds to FIG. 4 in the first embodiment.

As shown in FIG. 18, the suspension-type breaking machine 16 of the fourth embodiment differs from the suspension-type breaking machine 11 of the first embodiment in that the traveling directions of the traveling blades 87, 87 'are different. Is provided with a constriction 89 for hooking a bag-breaking piece F such as a plastic film after bag-breaking. A nozzle 91 for vacuum-sucking the bag-breaking piece is arranged at the downstream end where the traveling blades 87, 87 'rise from the bottom surface of the suspension-type bag-breaking machine 16. Except for this, the suspension type bag breaking machine 11 of the first embodiment is constructed in exactly the same manner, and therefore, corresponding elements are designated by the same reference numerals and their description is omitted.

According to the suspending type bag breaking machine 16 of the fourth embodiment, the broken bag fragment F can be removed from the contaminated material of the broken bag fragment F and the glass bottle G and the metal can C after the bag is broken. The next step of removing the broken bag pieces F from the metal can C may be omitted or simplified.

Although the respective embodiments of the present invention have been described above, needless to say, the present invention is not limited to these, and various modifications can be made based on the technical idea of the present invention.

For example, in the bag breaking apparatus 1 of the first embodiment, the hanging bag breaking machine 11, 12, 13, 21, 2 of the present invention is used.
Using the belt conveyor 30 in combination with 2, 23,
In the second embodiment, the inclined chute 28 is used in combination with the suspension-type bag breaking machine 14, but the waste bag conveying device combined with the suspension-type bag breaking machine of the present invention conveys with a substantially flat transfer surface. Any type of device may be used. For example, it may be an apron conveyor or a belt conveyor inclined upward in the conveying direction. Further, in the first embodiment, the belt 3 of the combined belt conveyor 30 is
Although the locking member 32 of the dust bag W is provided on one surface, the locking member 3
2 is not always necessary.

In each of the embodiments, the suspension-type bag breaking machine was used by suspending it on a fixed frame, but it was suspended on a frame dedicated to the suspension-type bag breaking machine, and wheels were attached to it. It may be a portable hanging type bag breaking machine.

In the fourth embodiment, the traveling blade 87,
Although the constriction 89 for hooking the broken bag piece F is provided on 87 ', a serrated small piece member may be attached.

[0056]

As described above, according to the suspending type bag breaking machine of the present invention, for example, a blade attached to the refuse bag conveying device is not necessary, and the bag itself has a bag breaking blade. Therefore, the selection range of the refuse bag conveying device to be combined is wide, and it suffices to simply dispose the device directly above the conveying surface of the existing ordinary belt conveyor.

Further, since the hanging type bag breaking machine itself has a blade for breaking the bag, and the hanging type bag breaking machine acts as a bag breaking machine even by itself.
These can be arranged in multiple rows and multiple stages as a unit, which is highly adaptable to large and small loads and can be easily added.

When the traveling blade is driven in the opposite direction by the suspension type bag breaking machine of claim 2, for example, the speed at which the dust bag is sandwiched is faster than that of the suspension type bag breaking machine having one fixed blade. Therefore, the bag breaking speed is high, and the bag can be broken in the same manner when the garbage bag is moved forward or backward.

According to the hanging type bag breaking machine of claim 4, for example, a bag breaking piece made of a plastic film or the like can be removed at the same time as the bag breaking of the garbage bag, so that the bag breaking operation usually performed in a later step. Omit or simplify the piece removal process.
