Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing waste jars such as cullet from waste jars as a pre-process for sorting waste jars in a waste bottle collection facility. Things.

[0002]

2. Description of the Related Art Waste bottles are selectively collected from the viewpoint of resource saving and effective use. When the waste bottles are collected and reused as resources, unless the bottles are collected by color, there is a problem that various colors are mixed and become different colors when dissolved as a raw material. For this reason, when sorting and collecting waste bottles, it is necessary to sort and collect them by color.

[0003] Waste bottles include bottles such as undamaged bottles, bottles partially missing at the neck and bottom, broken pieces such as the neck and bottom only, and 30 mm square. Since cullet and the like which are finely broken are mixed to a degree or less and fine cullet and the like are obstructed in the sorting and collection, it is necessary to remove them in advance.

FIG. 1 shows an example of such a sorting and collecting facility in which sorting is automatically performed by a machine. In this facility, waste bottles G are sent to the receiving hopper 2, and the waste bottles G are sent to the cullet c removing device 1 by the lower feeding conveyor 3, where the fine stuff such as cullet c (hereinafter referred to as cullet c) is sent. , Simply referred to as cullet c) and sent to the alignment device 4. In some cases, the waste bottles G are directly sent to the conveyor 3 without providing the hopper 2.

[0005] In the sorting device 4, bottles a and broken pieces b are aligned one by one (one by one) in the direction of the arrow and sent to the conveyor 6 of the color-specific detection device 5. Color-specific detection device 5
Then, the colors of the bottles a and the like that move one by one are identified by an imaging process or the like, and the next sorting device 7 sorts the bottles a and the like based on the identification information, and
Store in a.

In such a sorting and collecting facility, a cullet c removing apparatus 1 according to the present invention will be described with reference to FIG. Conveyor 10 with ...
The waste bottles G are sent from the conveyor 3 to the forward path of the conveyor 10, and the cullet c is dropped and removed from between the transport rollers 12 in the forward path of the transport so as not to interfere with the sorting.

[0007]

In the above-described removing apparatus 1, the gap between the transport rollers 12 is such that the bottles a and the broken pieces b having a selectable size and shape do not pass through and the cullet c passes through. For example, it is set to 30 mm to 40 mm, but the broken pieces b cannot pass through the gap between the rollers 12 due to their size and posture based on the falling energy from the conveyor 3 or the like, and do not slip out of the gap. There is.

[0008] When the broken pieces b are caught (clogged), the cullet c is not removed at that location, and the removal efficiency is reduced. In addition, the bottles a may collide with the sandwiched broken pieces b and be damaged. Furthermore, broken pieces b
Is too large (when the gap between the transport rollers 12 is clogged), the cullet c cannot be removed.
The apparatus 1 must be stopped and the broken pieces b must be removed manually, and the removal is dangerous because of the broken pieces b. Further, stopping the device 1 causes a decrease in work efficiency.

Further, in this type of removing apparatus 1, the cullet c is stored in a collecting container passing between the respective conveying rollers 12 in the reciprocating path (see Japanese Utility Model Laid-Open No. 6-60475). For this reason, there is a possibility that the broken pieces b that have finally passed through the forward path may be caught between the transport rollers 12 on the backward path,
If sandwiched, the above-described problem occurs.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to prevent a broken piece b from being caught (clogged) between respective transport rollers.

[0011]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, in the above-described removing apparatus 1, the transport roller is forcibly rotated on the outward path.

[0012] If the transport roller rotates forcibly in this way,
The broken pieces that have entered between the transport rollers are pushed up by the rotational force and come out of the gap, change their posture, and are transported without falling or being pinched through the gap. That is, clogging between the transport rollers is reduced as much as possible.

On the other hand, according to a second aspect of the present invention, between the reciprocating paths of the conveyer of the above-mentioned removing device 1, a receiving port of a cullet discharge chute faces the lower surface of the forward path, and the discharge chute is connected to the reciprocating path. The structure was guided to the side of the conveyor from between.

In this case, all the broken pieces that have finally fallen between the rollers on the outward path fall to the discharge chute, and do not fall on the return path. Therefore, clogging on the return path is eliminated.

As means for forcibly rotating the transport rollers, a chain or rack may be provided along the outward path of the conveyor, and a sprocket provided for each transport roller may be engaged with the chain or rack. (Claim 3).

According to this configuration, the conveyance roller is rotated by the engagement of the sprocket and the chain or the rack, following the movement of the conveyor, thereby effectively preventing the broken pieces from being jammed between the conveyance rollers. I do. At this time, if the chain is forcibly driven (claim 4), the conveying roller can be arbitrarily rotated without following the running of the conveyor, and the clogging of the broken pieces is most effective. A suitable rotation speed and direction can be selected.

Further, it is preferable that the transport roller is eccentrically rotated (claim 5). In this case, the transport roller runs while rotating so as to hit a wave, and clogging of the cullet is further reduced. .

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, too, a cullet c removing device 1 incorporated in a facility for collecting waste bottles G shown in FIG.
The details thereof are shown in FIG. 2 to FIG. 6, and as shown in FIG.
.. Are provided to form the conveyor 10.

As shown in FIG. 2, the conveyor 10 is wound around a sprocket 13 at both upper and lower ends of a frame F and a driving sprocket 13b at another lower end of the frame F. When the sprocket 13b rotates via the, it runs in the direction of the arrow. In the figure, reference numeral 13a denotes a bearing of the sprocket 13.

As shown in FIG. 6, the transport roller 12 has a support shaft 12c inserted at both ends of a pipe 12b whose outer peripheral surface is covered with urethane rubber 12a and is screwed, and the support shaft 12c is connected to a guide rail. 14 is a bearing type wheel 14
The guide rail 14 is supported so as to be able to travel freely through the guide rail 14. The end of the support shaft 12c is supported by a receiving cap 15 fixed to the chain 11 via a bearing 15a. As the chain 11 travels, the transport roller 12 travels on the rail 14. That is, the conveyor 10 is shown in FIG.
Drive in the direction of the arrow.

As shown in FIG. 2, a chain 16 is driven by a motor 16c to move the sprocket 1 above the forward path of the conveyor 10.
6a, the sprocket 17 fixed to the support shaft 12c of each transport roller 12 on the outward path of the conveyor 10 is engaged with the chain 16, and the traveling of the chain 16 causes the chain 16 shown in FIGS. Force to rotate forward as indicated by the arrow. That is, the chain 1 is
6 runs fast. Note that the traveling speed and traveling direction (including the direction opposite to the arrow) of the chain 16 may be appropriately selected in consideration of the effect of preventing the clogging of the broken pieces b described later.
The rotation speed and rotation direction of 2 are arbitrary.

A receiving port 18a of the discharge chute 18 faces the entire area of the lower surface of the conveyor 10 (see FIG. 3). ing. For this reason, the broken pieces b and the cullet c passing between the transport rollers 12 on the outward path surely fall on the discharge chute 18 and the transport rollers 12 on the return path.
Without falling down, it is guided to the side of the device 1, stored in a bucket or the like, and moved to a required place.

An alignment conveyor (alignment device) 4 is disposed at the end of the conveyor 10, and broken pieces b and bottles a that have not passed between the rollers 12 are fed through a payout plate 20. In this alignment conveyor 4, a pair of belt conveyors 4a, 4a are arranged in a V-shape (see FIG. 2), and bottles a from the conveyor 10 of the removing device 1 enter the bottom portion of the V-shape. Then, they are arranged one by one and sent to the conveyor 6 of the color-specific detection device 5.

This embodiment is configured as described above. Now, when the waste bottles G are sent from the conveyor 3 onto the conveyor 10, the bottles a are in any posture,
As shown in FIG. 7 (a), the roller 1
Almost point contact with 2. At this time, if the roller 12 is rotating by running the chain 16,
The bottles a rotate around the contact point as shown by an arrow as shown in FIG. 7A, and become the most stable state (parallel alignment state) fitted between the rollers 12 as shown in FIG. The conveyor 10 is conveyed. For this reason, the bottles a are fed into the alignment conveyor 4 in the running direction with the length direction thereof.

Further, the broken pieces b and the cullet c are sent from the conveyor 3 together with the bottles a, and a part of the broken pieces b and the cullet c fall between the rollers 12 to the discharge chute 18. As shown in FIG.
Even if the broken pieces b are caught (clogged) between the two, the attitude of the roller 12 is displaced as indicated by a dashed line due to the spinning of the roller 12 and the like, so that the attitude changes and the roller 12
The paper is conveyed forward without passing through the gap or clogging between the rollers 12. For this reason, it is possible to minimize the possibility of reaching the return path with the broken pieces b sandwiched between the rollers 12. Further, the clogging between the rollers 12 is eliminated and the rollers 12 are rotatable, so that the aligning operation of FIG. 7 is also performed smoothly.

In this way, the cullet c and some broken pieces b which hinder the sorting are removed, and the bottles a and the like arranged in the horizontal direction are sent to the aligning device 4, and furthermore, the conveyors thereof The images are aligned one by one by 4a and 4a and sent to the color-specific detection device 5. In the color-specific detection device 5, as in the conventional case, the bottles a and the like that move one by one are identified by the imaging process and the like, and the color is identified in the next sorting device 7 based on the identification information. And sort the required bucket 7a
Store in ...

In the above embodiment, the chain 16 is run. However, the chain 16 may be simply extended along the outward path of the conveyor 10 without running, or may be replaced with a rack in which the sprocket 17 meshes. At this time, the chain and the rack can be provided on the rail 14 side.
According to the chain, the rack, etc., the transport roller 12 surely rotates, but the transport roller 12 can be forcedly rotated by the rolling of the wheels 14 a on the rails 14.
The forced rotation mechanism such as 6 may be omitted. Instead of providing the discharge chute 18, the cullet c and the broken pieces b may be structured to pass through the reciprocating path of the conveyor 10, and may be stored in a lower portion of the lower part by a bucket or the like. Further, the forced rotation of the roller 12 need not necessarily be performed as long as no clogging occurs. That is, only the discharge chute 18 may be used.

Further, as shown in FIG.
When the pipe 12b is decentered with respect to the support shaft 12c, for example, by interposing a filling 12d between the support shaft 12c and the pipe 12b, the transport roller 12 will rotate so as to hit a wave. Roller 12
The clogging is further prevented.

Further, the receiving hopper 2 can be removed. Conversely, the conveyor 3 is removed and the hopper 2 is removed.
The bottles a may be sent directly onto the conveyor 10 from the container.

[0030]

The present invention is configured as described above.
Clogging of broken pieces that hinder cullet removal can be minimized, cullet that hinders sorting can be efficiently removed, and workability can be improved.
At this time, if the roller rotates, the bottles can be aligned.
