Description

[Detailed Description of the Invention] +al Industrial Field of Application The present invention relates to a bag-breaking machine, and more specifically, the bag-breaking machine is configured to break thrown garbage bags, etc., using a weighted bag-breaking blade that swings within a rotating drum. Regarding bag breaking machines.

This is used in the field of processing equipment that removes garbage from plastic bags or cardboard boxes containing garbage prior to crushing the garbage, and recycles collected household waste in bags.

(bl) Prior Art Generally, garbage generated from households is placed in plastic bags or cardboard boxes, and the garbage also includes reusable empty bottles and empty containers.

Therefore, a bag tearing machine is used to tear plastic bags and cardboard boxes as a preparatory work for taking out the reusable items.

By the way, conventional bag-breaking machines have a spiral blade installed inside a rotating drum, and tear plastic bags, etc. placed on the blade, using a weighted bag-breaking blade that is swingably suspended. When the bag or the like is torn, the empty bottle or the like inside falls into the spiral groove between the blades, and is then transported to the discharge port by the blade.

However, with the above structure, the bottom of the spiral groove is the inner surface of the metal rotating drum, so there are only 1 empty bottles, etc. ! I
If it falls into the spiral groove, it will hit the inner surface of the rotating drum, making noise and often causing damage.Furthermore, even when it is being transferred by a blade, it will be rolled at the bottom of the spiral groove, making noise and causing damage. This poses problems in that it causes noise pollution and makes it difficult to collect reusable empty bottles.

(C) Problems to be Solved by the Invention The present invention solves the above problems by providing an elastic member in tension at the bottom of the spiral groove formed by the spiral blade, that is, on the inner surface of the rotating drum.

(dl Means for Solving the Problems) The present invention provides a rotary drum having an input port and a discharge port at the front and rear, and a blade that forms a protruding claw is spirally provided on the inner surface of the rotating drum, and the bottom of the spiral groove formed by the blade is An elastic member is stretched over the rotating drum, and a support shaft is provided passing through the rotating drum, and a weight having a bag-breaking blade is placed close to the blade and swingably supported on the support shaft. It is related to bag machines.

(e) Examples Hereinafter, the present invention will be explained in detail based on examples thereof.

Figure 1 is an overall sectional view of the bag tearing machine, with front and rear rollers IA and I.
The rotating drum 2 rotatably supported at B is closed at its front and rear by a front wall 4 and a rear wall 5 which are vertically fixed to a base 3.

An input port 4a and a discharge port 5a are opened in the sixth wall 4.5, and chutes 4b and 5b are attached.

The rotating drum 2 is rotated in the circumferential direction by a driving means (not shown) horizontally or in a downwardly inclined state toward the discharge port 5a, and a spiral blade 6 is attached to the inner circumference thereof. This has a large number of protruding claws 9 on the inner edge for moving a plastic bag 8 containing garbage 7 in the rotational direction, and the interval between adjacent blades 6.6 is narrow on the input port 4a side, The exit 5a side [is wider. In the illustrated example, the plastic bag 8 has two spirals near the weight 12, which will be described later, and is not torn.
etc. are placed on the blade 6. In addition, the spiral groove 6a formed between the adjacent blades 6,
The trash 7 that has been torn and taken out and the damaged plastic bag fit into it and do not interfere with the tearing of the next plastic bag 8, and as the rotary drum 2 rotates, they are sequentially removed from the discharge port. It is designed to move in the direction 5a.

An elastic member 14 made of rubber or the like is stretched on the bottom of the spiral groove 6a, that is, on the inner surface of the rotating drum 2, and this elastic member 14 allows empty bottles and the like to be pulled out of the plastic bag 8 into the spiral groove 6a.
It does not make any noise even if it falls on someone, and it also prevents damage. Further, noise and damage can be prevented even during transfer by the blade 6.

As shown in FIG. 2, a support shaft 10 is installed in the rotary drum 2 and extends through the rotary drum 2 below the central axis 2a. A weight 12, on which a plurality of bag-breaking blades II are attached in the direction, is swingably supported.

Note that the support shaft lO also passes through the front wall 4 and the rear wall 5 shown in FIG.
Supported by 3B.

Since the support shaft 10 is located below the central axis 2a of the rotating drum 2, when the plastic bag 8 is inserted between the weight 12 and the blade 6 and the weight 12 rotates together with the rotating drum 2, the weight is removed. 12 and the blade inner end 6b gradually widens as shown by the imaginary line in FIG. In other words, when the plastic bag 8 rises too high, the contact force with the weight 12 is weakened, and as a result, the weight 12 is swung back forcefully by its own weight, and at this time, the plurality of bag-breaking blades 11 lined up in the circumferential direction are It acts to tear the top of the plastic bag 8. In addition, if the bag-breaking blade 11 is also arranged in the axial direction of the weight 12 as shown in FIG. 1, one weight 12 can break a plurality of plastic bags 8 at once. Further, the shape may be a sharp one or a rectangular shape as shown in the figure. Further, it may be attached radially from the support shaft 1o of the weight 12, but if it is tilted in the rotation direction 2A of the rotating drum 2 as shown in the figure, plastic bags, strings, etc. It's convenient because it doesn't get involved. Incidentally, the reason why the weight 12 is located to the left of the central axis 2a in FIG. 2 is because the input port 4a is opened to the right of the weight 12.

According to the embodiment with such a configuration, the plastic bag 8 is easily broken with the bag breaking blade 11 in the following manner, and the removed garbage is moved smoothly and without damage (moved to the discharge port). be able to.

When the plastic bags 8 containing the garbage 7 are sequentially inputted from the input port 4a, as the rotating drum 2 rotates, they are
It moves in the circumferential direction by a protruding pawl 9 attached to the spiral blade 6.

The weight 12 is attached to the support shaft 10 regardless of the rotation of the rotating drum 2.
When the plastic bag 8 reaches there, the bag-breaking blade 1 on the outer periphery of the weight 12
The weight 12 is sandwiched between the rotary drum 1 and the spiral blade 6, and the contact force causes the weight 12 to rotate in the rotation direction 2A of the rotary drum 2. As the plastic bag 8 moves to be further lifted by the protruding claw 9, when the gap between the bag tearing blade 11 and the spiral blade 6 becomes wider and the contact force weakens, the weight 12 is suddenly swung back by its own weight. . As a result, the plurality of bag tearing blades 11 lined up on the outer peripheral surface rub against the top of the plastic bag 8 and tear it.

The garbage 7 is taken out from the torn plastic bag 8 and fits into the spiral groove 6a. Therefore, when the next plastic bag 8 reaches the weight 12, the same operation is repeated.

At this time, since the elastic member 14 is stretched over the bottom of the spiral groove 6a, no noise is generated even if the garbage 7 falls into the spiral groove 6a, and damage can also be prevented.

Thereafter, the garbage 7 is moved toward the discharge port 5a by the spiral blade 6, and is discharged from the discharge port 5a through the chute 5b.

Even at that time, the garbage 7 rolls in the spiral groove 6a,
Since the elastic member 14 is stretched at the bottom of the spiral groove 6a, noise and damage are prevented.

(f) Effects of the Invention As described above, in the present invention, an elastic member is provided at the bottom of the spiral groove formed by the spiral blade, so that when garbage falls into the spiral groove or moves inside the spiral groove, When doing so, it is possible to reliably prevent the generation of noise and damage to trash, which is the case with conventional methods.
