TECHNICAL FIELD OF THE INVENTION
The present invention relates to a glass bottle sorting apparatus, and more particularly, to provide a glass bottle sorting apparatus in which a broken glass piece does not hinder smooth transport of a normal glass bottle.
[0002]
[Prior art]
Glass bottles are effectively and efficiently recycled by identifying and sorting their properties (eg, color and shape). Various glass bottle sorting devices have been developed as devices for that purpose.
[0003]
An example of this type of glass bottle sorting apparatus will be described with reference to FIG.
As shown in FIG. 11, the glass bottle sorting apparatus 100 includes a vibrating conveyor 101, a conveyor 102, an image processing apparatus 103, and a distribution unit 104.
The vibrating conveyor 101 is loaded with broken glass bottle fragments and unbroken normal glass bottles in a mixed state. The vibrating conveyor 101 moves the broken bottle fragments and the normal glass bottle while vibrating them, separates the broken bottle fragments from the normal glass bottle, and aligns the normal glass bottle. Here, when aligning normal glass bottles, for example, the direction from the upper end to the lower end of each glass bottle is made to coincide with the transport direction of the glass bottle.
[0004]
On the conveyor 102, the normal glass bottles arranged by the vibrating conveyor 101 are transported as they are. In the image processing device 103, the properties of the glass bottle being conveyed by the conveyor 102 are identified. The sorting means 104 sorts the glass bottles according to the identification result by the image processing device 103. As described above, in the glass bottle sorting apparatus 100, five steps of separation, alignment, conveyance, identification, and distribution are performed.
[0005]
As shown in FIG. 12, the conveyor 102 is provided with guide plates 106 for aligning the glass bottles 105 in a row in the same direction (one by one). The guide plate 106 is formed by disposing two parallel plates at a predetermined interval for passing one glass bottle 105 on the conveyor of the conveyor 102. As shown in FIGS. 12B and 12C, these two parallel plates are provided apart from each other by a gap A so as not to contact the traveling belt of the conveyor 102.
[0006]
[Problems to be solved by the invention]
As described above, in the conventional glass bottle sorting apparatus 100, broken glass bottle fragments and normal glass bottles are separated on the vibration conveyor 101, and only the normal glass bottles are conveyed by the conveyor 102. However, a broken glass piece may be generated during transportation due to an impact or the like when a normal glass bottle transfers from the vibration conveyor 101 to the conveyor 102. Further, the vibrating conveyor 101 may not be completely separated, and broken glass bottle fragments may be conveyed by the conveyor 102 together with a normal glass bottle. These broken glass bottle fragments are discharged from the conveyor 102 through the gap A during the transportation.
[0007]
In this case, a piece of the broken glass bottle may be caught or clogged in the gap A, and smooth conveyance may be hindered. Since glass fragments generally have a sharp tip, they penetrate a conveyor belt and cause a failure, or stop the conveyor 102, which hinders the flow for automatic sorting of glass bottles. was there.
[0008]
The present invention has been made in view of the above circumstances, and aims to achieve the following objects.
An object of the present invention is to provide a glass bottle sorting apparatus in which a broken glass piece does not hinder a smooth transfer of a normal glass bottle.
Another object of the present invention is to provide a glass bottle sorting apparatus capable of normally transporting only normal glass bottles.
Still another object of the present invention is to provide a glass bottle sorting apparatus capable of forming a means for normally transporting only a normal glass bottle with simple configuration means.
It is still another object of the present invention to provide a glass bottle sorting apparatus which sorts a normal glass bottle from broken glass fragments and facilitates transportation of the normal glass bottle for sorting and sorting.
Still another object of the present invention is to provide a glass bottle sorting apparatus that sorts a normal glass bottle from broken glass pieces, smoothes the transfer of the normal glass bottle for sorting and sorting, and improves the sorting accuracy. Is to do.

[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, a glass bottle sorting apparatus of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows a first embodiment of a glass bottle sorting apparatus according to the present invention.
In FIG. 1, reference numeral 200 denotes a glass bottle automatic sorting apparatus according to the present embodiment.
[0015]
The automatic glass bottle sorting apparatus 200 includes a separating unit that separates a broken glass piece from a normal glass bottle that is not broken, an aligning unit that aligns only the normal glass bottle separated by the separating unit, and the aligning unit. Transport means for transporting only the normal glass bottles arranged according to the above, identification means for identifying the normal glass bottles transported by the transport means by color and shape during their transport, and the identification means Sorting means for sorting the normal glass bottles according to color and shape according to the identification result. Here, as the identification means, generally, a color recognition means using a filter, a shape recognition means by computerized image processing, and the like are used.
[0016]
Into the charging box 1, normal glass bottles and broken glass pieces (not shown) are charged in a mixed state. The input box 1 is vibrated by vibrating means (not shown). At the center of the input box 1, a central separator 2 is fixed. The two slopes on both the left and right sides of the input box 1 and the left and right slopes of the central separator 2 form two pairs of slope-like lead-out portions 3. The inclined lead-out portion 3 supports the outer peripheral portion of the normal glass bottle, and aligns the axis of the normal glass bottle so as to be aligned.
[0017]
The conveying means 4 conveys the normal glass bottle drawn out from the slope-shaped deriving section 3 in the conveying direction indicated by the arrow a. The transport unit 4 is provided with two transport units 5 and 5 on which a normal glass bottle is placed. The two conveying sections 5, 5 correspond to the leading-out directions of the two pairs of sloped leading-out sections 3 and extend in the carrying direction a. It is preferable that the transport directions by both transport units 5 are parallel. Each transport unit 5 is formed of a pair of two rotating bodies (extended members) 6 and 7 extending in the transport direction a. The rotating bodies 6 and 7 are formed in the shape of a cylinder (pipe) having the same diameter as each other. In this case, the rotating bodies 6 and 7 may be cylindrical instead of cylindrical.
[0018]
As shown in FIGS. 2 and 3, a gap (space) 8 is provided between the pair of two rotating bodies 6 and 7 so as to extend in the transport direction a. The minimum distance of the gap 8 is formed smaller than the maximum diameter of a normal glass bottle (not shown) conveyed in the conveyance unit 5. Therefore, the gap 8 between the two rotating bodies 6 and 7 does not cause the normal glass bottle transported in the transport unit 5 to drop by gravity. On the other hand, the gap 8 gravitationally drops broken glass bottle fragments smaller than the normal glass bottle. In some cases, broken pieces of the glass bottle are blown out by the rotating bodies 6 and 7 to the outside, and are removed from the transport unit 5.
[0019]
The gap 8 extending in the transport direction a guides a normal glass bottle discharged from the sloped lead-out portion 3 to a predetermined position in the transport portion 5 where the normal glass bottle is to be placed. Function as That is, if there is no gap 8 or concave portion in the transport unit 5 and the transport surface of the transport unit 5 is flat, the normal cylindrical glass bottle having a substantially cylindrical shape swings in the circumferential direction on the transport surface. Although the position of the vial moves and the position is not determined, the provision of the gap 8 allows a part of the normal glass bottle to be accommodated in the gap 8 and the position in the transport unit 5 to be determined. Therefore, the guide plate 106 unlike the conventional example becomes unnecessary. Thereby, the site itself such as the gap A (see FIG. 12), which was conventionally clogged with broken glass pieces, can be eliminated. In addition, as described below, the gap 8 is provided with a transmission window for transmitting an external force (such as a pressing force or an urging force) for removing (removing) the normal glass bottle from the transport unit 5 to the normal glass bottle. Function as
[0020]
An extruding section (distributing means) 9 is provided in the gap 8 so as to be able to move up and down. The extrusion unit 9 pushes out a normal glass bottle placed on the transport unit 5 from the transport unit 5 by protruding and retracting in the transport unit 5. As shown in FIG. 2, the extruding portions 9 are arranged in the gap 8 at predetermined intervals in the transport direction a. As shown in FIG. 3, the tip of the push-out portion 9 is formed on a slope 11.
[0021]
Regarding the direction and angle of the slope 11 at the tip of the push-out section 9, the normal glass bottle pushed out by the push-out section 9 is carried out to the sorting storage box 12 (see FIG. 1) arranged on the side of the transport section 5. It is designed to be. The timing of raising and lowering the push-out unit 9 is controlled in accordance with the result identified by the identification device 10 so that a normal glass bottle is stored in each sorting storage box 12 according to color and shape. In FIG. 1, the sorting storage box 12 is provided only on the outer side of each transport unit 5, but may be provided on the inner side.
[0022]
As shown in FIG. 3, each of the rotating bodies 6 and 7 rotates at a constant speed from the inside of the gap 8 to the outside (outward, see the arrow C in FIG. 3) in opposite directions. Here, the outward direction refers to a direction in which a normal glass bottle in contact with each of the rotating bodies 6 and 7 is guided upward (in a direction opposite to the direction of gravity). Thus, since the rotating bodies 6 and 7 rotate outward from each other, a normal glass bottle on the rotating bodies 6 and 7 is not drawn into the gap 8.
[0023]
The identification device 10 includes a CCD camera equipped with various filters, a shape analyzer that can determine the size and shape of the glass bottle from two-dimensional information of the CCD camera, and the like.
[0024]
In the present invention, it is preferable that at least one of the two rotating bodies 6 and 7 is formed of a pipe. More preferably, the rotation axes of the two rotating bodies 6 and 7 are coaxial. It is preferable that the axis of rotation of the rotating bodies 6 and 7 is inclined with respect to the horizontal direction. That is, it is preferable that the common tangent plane of the rotating bodies 6 and 7 is inclined with respect to the horizontal plane and gradually descends in the forward direction in the transport direction a. The inclined common tangent plane transfers the glass bottle on the transport surface formed by the rotating bodies 6 and 7 in the transport direction a. Also, the inclination of the common tangent plane does not prevent the glass fragments from falling by gravity.
[0025]
The pipes forming the rotating bodies 6, 7 need not be cylindrical but can be conical in shape, the axis of which is inclined and the common tangent plane of the two conical bodies is inclined. It is preferable that the normal glass bottle slides on the inclined plane and moves in one direction.
[0026]
Next, with reference to FIGS. 4 and 5, a modified example of the distribution unit applied in the first embodiment will be described. Below each gap 8, a vertical air injection means 21 is provided. A plurality of vertical air injection means 21 are provided at predetermined intervals in the transport direction a, and inject air substantially vertically upward from an air injection port at the tip thereof. A horizontal air injection means 22 is provided above and on the side of the pair of rotating bodies 6 and 7. The horizontal direction air jetting unit 22 jets air horizontally from the side toward the normal glass bottle placed above the pair of rotating bodies 6 and 7 (transporting unit 5). As a result, the normal glass bottles are sorted into the sorting storage boxes 12 according to their properties.
[0027]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0028]
As shown in FIG. 6, in the present embodiment, each transport unit 25 is provided instead of each transport unit 5 of the first embodiment. The transport unit 25 includes a pair of four linear bodies (extended members) 31 on which a normal glass bottle is placed similarly to the transport unit 5 and extends in the transport direction a (see FIG. 7). .
[0029]
Each filament 31 is a wire having elasticity. As shown in FIG. 7, gaps (spaces) 80 are provided between each of the pair of four filaments 31. These gaps 80 are provided at three places between the four filaments 31. The relationship between the minimum distance between the gaps 80 (the width between the adjacent filaments 31) and the normal glass bottle 32 being conveyed is the same as in the first embodiment. That is, the gap 80 does not cause the normal glass bottle 32 to drop by gravity, but only causes the broken pieces of the glass bottle to drop by gravity.
[0030]
As shown in FIGS. 7 and 8, the four striated bodies 31 are arranged at equal intervals so that the glass bottle 32 in the mounted state is arranged along a part (arc surface) of the imaginary cylinder. Have been. The glass bottle 32 is supported on these four filaments 31. Each striated body 31 is a resin-made cord having elasticity such as an elastomer. The striated body 31 is elastically deformed so as to appropriately increase the width of the gap 80 when the glass fragments are dropped from the gap 80 between the striated body 31 and the adjacent striated body 31. As shown in FIG. 6, since the front and rear ends of the linear body 31 in the transport direction a are only wound around the rollers 26 and 26 and are not supported (restricted) in an intermediate region in the transport direction a, The gap 80 is easily elastically deformed to enlarge the gap 80 so that the glass fragments can be easily dropped.
[0031]
As shown in FIG. 6, each linear body 31 is an endless belt wound between a pair of rollers 26, 26 disposed at the front and rear ends in the transport direction a. FIG. 7 shows a cross section of the roller 26 perpendicular to the transport direction a (in FIG. 7, the dashed line drawn in the horizontal direction indicates the rotation axis of the roller 26, and The portion of the lower roller 26 is omitted). As can be seen from FIG. 7, which can be partially omitted, the roller 26 is formed in mirror symmetry with respect to a horizontal plane including the rotation axis of the roller 26. Therefore, hereinafter, by referring to FIG. 7, the description of the upper side from the horizontal plane will be replaced with the description of the entire configuration of the roller 26.
[0032]
The upper half of the roller 26 shown in FIG. 7 is formed in a substantially U-shape in which a concave portion is formed on the upper part. In the recessed surface portion, two semicircular grooves 45a recessed downward are formed at predetermined intervals in the left-right direction in FIG. Further, semi-circular grooves 45b that are recessed downward are formed one by one in the non-recessed surface portions provided on the left and right sides of the concave surface portion, respectively. These groove portions 45a and 45b are formed as ring grooves continuously provided in the entire circumferential direction of the roller 26, so that the filament 31 can be wound in the circumferential direction. When the pair of rollers 26, 26 are driven to rotate, the four filaments 31 move at a constant speed in the transport direction a, and move the glass bottle 32 on the filaments 31 in the transport direction a.
[0033]
With reference to FIG. 9, the distribution means 40 applied to the present embodiment will be described.
As described above, the filament 31 is wound around the pair of rollers 26 as an endless belt and is driven to rotate. The distributing means 40 includes a portion of the linear body 31 that moves in the transport direction a and becomes the forward path (the transport unit 25) and a part of the linear body 31 that moves in the opposite direction to the transport direction a and forms the return path. And between them. The striated body 31 shown in FIG. 9 shows a part of the striated body 31 to be the outward path (outward path portion). A body 31 portion is provided.
[0034]
The distribution means 40 includes a cylinder 33 and a fork 34 provided on a piston rod 33a of the cylinder 33. Three forks 34 are provided, and are provided so as to extend at predetermined intervals in the extending direction of the piston rod 33a. Each fork 34 is sized and shaped to be able to enter and exit the gap 80 as the piston rod 33a moves forward and backward. The intervals between the forks 34 are provided corresponding to the intervals between the striated bodies 31.
[0035]
The cylinder 33 is disposed such that the axis of the piston rod 33a (or fork 34) is inclined rightward in FIG. 32 is pushed to the right. The sorting means 40 is provided on the side of the separation storage box 12 so that the extruded glass bottle 32 is stored in the separation storage box 12.
[0036]
According to the second embodiment, the conveying means for forcibly conveying the glass bottle 32 by rotating and driving the endless belt (the linear body 31) by the roller 26 is used. For this reason, unlike the transfer means using the rotating bodies 6 and 7 of the first embodiment, the transfer speed in the transfer direction a can be reliably made constant. Therefore, if the fork 34 is moved up and down at the timing of elevating and lowering the fork 34 obtained according to the result identified by the identification device 10 in the middle of the transport path by the transport unit 25, the desired glass bottle 32 can be stored in the desired separated storage. It can be extruded toward the box 12, and the distribution accuracy is improved. In other words, the transport means 26, 31 and the like of the present embodiment ensure synchronization for identification and separation. That is, since the conveying speed is constant, the sorting means 40 is operated after a fixed time from the time of the fixed point identification, so that the normal glass bottle 32 can be reliably stored in the sorting storage box 12 at the predetermined position. it can.
[0037]
In the present invention, it is preferable that the extension member (the linear body 31) that moves in the transport direction is composed of four wires. Preferably, the four wires are arranged in mirror symmetry with respect to one vertical plane. The wire can be formed, for example, as a metal wire, an elastomer string, or the like. Here, the material of the wire is preferably rubber or the like for the following reasons. First, when the wire receives the normal glass bottle sent from the previous stage, it is suitable for buffering and absorbing the impact. Secondly, because the frictional force (friction coefficient) is high, when the normal glass bottle is being conveyed by the wire, the normal glass bottle is suitable for being conveyed without slipping.
[0038]
Next, with reference to FIG. 10, a modified example of the distribution unit 40 (the distribution unit 41) will be described. As shown in FIG. 10, the transport unit 25 to which the glass bottle 32 is transported is configured by two members 42, and the sorting unit 41 is applied to, for example, such a transport unit 25. The distributing means 41 includes a cylinder 43 and an extruding portion 44 provided at a tip of a piston rod 43a of the cylinder 43. The cylinder 43 is provided so that the axis of the piston rod 43a is in a vertical direction, unlike the cylinder 33 of the distribution means 40. The push-out portion 44 provided at the distal end of the piston rod 43a is formed to be inclined rightward in FIG. 10, so that the glass bottle 32 is pushed rightward.
[0039]
The member 42 configuring the transport unit 25 illustrated in FIG. 10 may be the striated body 31 or the rotating bodies 6 and 7. Therefore, the distributing means 41 can be applied in the second embodiment in place of the distributing means 40, and can also be applied in the first embodiment in place of the extruding section 9 and the air ejecting means 21 and 22. It is.
[0040]
As described above, the gaps 8 and 80 in the first and second embodiments do not move in the transport direction a with the moving member (for example, the conveyor belt) that moves in the transport direction a as in the conventional example. It is not a movable gap formed between the fixing member (the guide plate 106). The gaps 8 and 80 are either a member that moves at a constant speed in the transport direction a (for example, the two linear bodies 31) or a member that does not move in the transport direction a (for example, the two rotating bodies 6). , 7), and in any case, there is no relative movement difference between the members (for example, the striated body 31, the rotating bodies 6, 7) in the transport direction a. Accordingly, the broken glass fragments do not penetrate the conveyor belt or the like between the gaps 8 and 80 and fall without receiving resistance from the gaps 8 and 80.
[0041]
A glass bottle sorting apparatus according to the present invention separates a broken glass piece from a normal glass bottle and arranges and transfers the normal glass bottle so as to have five processes of separation, alignment, conveyance, identification, and distribution. Needless to say, it may include a means and a sorting means for identifying a normal glass bottle being transported by the transporting means and being transported according to its properties, and sorting and sorting according to the identification result.
[0042]
【The invention's effect】
According to the glass bottle sorting apparatus of the present invention, it is a glass bottle sorting apparatus provided with a transport unit that separates a broken glass piece and a normal glass bottle and transports the normal glass bottle, wherein the transport unit is arranged in a transport direction. A plurality of extending extension members are provided, and a space is formed between each of the extension members so as to drop the broken glass piece but not to drop the normal glass bottle. Is conveyed by the conveying means, while the broken glass piece falls almost without resistance from the space portion, and thus, the separation work of the normal glass bottle and the broken glass piece makes it possible to carry the work. There is no hindrance. That is, unlike the conventional example, the broken glass piece does not interfere with the conveyer portion and is not clogged. Further, in this case, according to the present apparatus, at least one of the two extending members on both sides of the space is a rotating body that rotates from the inside of the space to the outside. The broken glass piece is swept toward the outside (upward) of the space by the rotating body that rotates from the inside of the space to the outside between the extension members. Thereby, for example, even in a case where the broken glass piece is large and the broken glass piece is hard to fall from the space portion between the extension members and the like, the broken glass piece is kept between the extension members. From the space, the suspension is released by a slight rotation or the like, and the suspension state is released. In this case, since the rotating direction of the rotating body is a direction of rotating from the inside of the space to the outside, the broken glass piece is pressed and caught on the extension member or the like inside the space. No piercing or piercing. Further, when the normal glass bottle is conveyed by sliding between the extension members, for example, the normal glass bottle is moved by the rotating body, whereby the normal glass bottle is moved to the extension member by its own weight. The contact pressure is reduced, and as a result, an effect is obtained that the frictional force between the normal glass bottle and the extension member is reduced to facilitate the sliding (sliding).
[0043]
According to the glass bottle sorting device of the present invention, in the glass bottle sorting device according to claim 1, the two extending members on both sides of the space portion are respectively opposite to each other from the inside of the space portion to the outside. Because the rotating body rotates at a constant speed, when the broken glass piece is swung by the rotating body, the broken glass piece is pressed at a constant speed (equal force) from both sides, and the broken glass piece is pressed from both sides. Due to the biasing of the pressing force to either direction, the broken glass piece does not pierce the extension member or the like inside the space. Further, since the rotating bodies on both sides of the space portion rotate at a constant speed in opposite directions from the inside of the space portion to the outside, the broken glass pieces are formed in the space from both sides of the space portion. It is guided with equal force toward the center of the portion, effectively preventing suspension between the extension members, and the like, and is quickly transported to (the center of) the space portion to form the broken glass piece. Is promoted. Further, for any reason, even when the broken glass piece tries to pierce or catch the extension member or the like on the inner side of the space portion, the rotating body still pierces the broken glass piece. The broken glass piece is flipped (flipped up) in a direction opposite to the direction in which it is hooked (the direction from the inside of the space portion to the outside), so that sticking or catching is effectively prevented.
[0044]
According to the glass bottle sorting device of the present invention, in the glass bottle sorting device according to claim 1 or 2, since at least one of the extension members, which is the rotating body, is formed by a pipe, compared with a solid one. Lightweight and easy to increase mechanical strength.
[0045]
According to the glass bottle sorting apparatus of the present invention, it is a glass bottle sorting apparatus provided with a transport unit that separates a broken glass piece and a normal glass bottle and transports the normal glass bottle, wherein the transport unit is arranged in a transport direction. A plurality of extending extension members are provided, and between each of the extension members, a space is formed which drops the broken glass piece but does not drop the normal glass bottle, and a space on both sides of the space is formed. Since the two extension members move at a constant speed in the transport direction, the normal glass bottle on the extension member is forcibly transported as the extension member moves. Therefore, since the normal glass bottle transfer speed can be kept constant, it is possible to reliably synchronize with the identification operation of the properties of the glass and the sorting operation according to the identification result, and improve the accuracy of the sorting operation and the like. Can be done.
[0046]
According to the glass bottle sorting apparatus of the present invention, in the glass bottle sorting apparatus according to claim 4, since the extension member that moves in the transport direction is an endless rubber belt, the normal glass bottle sent from the previous stage can be used. When received by the rubber belt, it is easy to buffer and absorb the impact, and since the coefficient of friction is relatively high, when the normal glass bottle is being conveyed by the rubber belt, the normal glass bottle does not slide. Therefore, it is possible to obtain an effect that it is easy to surely convey and easily maintain the conveying speed. Further, the rubber belt is elastically deformed when the relatively large broken glass piece is about to fall from the space portion, thereby slightly increasing the width of the space portion and smoothly breaking the broken glass piece. Let it fall.
