Description

Technical Field

[0001] The present invention relates to a multi-stage vibration feeder for manual sorting as a highly functional manual sorting line.

Background Art

[0002] Conventionally, a conveyor for manual sorting is known as a manual sorting line for visually manually sorting objects to be sorted including waste such as construction waste and resource waste.

[0003] As an example of a conveyor for manual sorting, there is a conveyor for manual sorting described in Patent Document 1. The conveyor for manual sorting described in Patent Document 1 includes a conveyor on which an object to be sorted in which objects to be sorted are mixed is placed and conveyed, and a partition plate that faces the upper surface of the conveyor and is arranged substantially parallel to the conveying direction thereof. It is a conveyor for manual sorting in which the sorted objects to be sorted are placed and conveyed in the area partitioned by the partition plate.

[0004] However, in the above-described conventional example of a conveyor for manual sorting, in the manual sorting line, the amount of sorted products actually sorted is unknown, and it can only be confirmed visually. In addition, optimization of the speed at which the manual sorting operator can optimally sort and optimization of flowing the objects to be sorted within the reach of the manual sorting operator's hand have not been achieved.

[0005] Sorting by a belt conveyor causes severe wear of the belt, and the belt is likely to be cut by metal, aggregates containing steel bars, etc. Therefore, there has been a problem that the running cost burden is large.

[0006] Also, in the case of sorting by a belt conveyor, when dropping from the belt conveyor, dust is generated, so it was necessary to collect dust with a dust collector.

[0007] Furthermore, in the case where the manual sorting line is a belt conveyor, an accident may occur in which an operator is caught in a rotating object (roller) during the sorting operation and cleaning operation.

[0008] On the one hand, in order to achieve the SDGs (Sustainable Development Goals), manual sorting by sorters is an important means. Appropriate waste management and recycling of waste such as construction waste and resource waste bring positive impacts related to many SDGs, such as efficient use of resources, reduction of greenhouse gas emissions, and protection of biodiversity and ecosystems. Also, by improving the functionality on the manual sorting line, the safety of manual sorters can be enhanced.

Embodiments for Carrying Out the Invention

[0018] Embodiments of the present invention will be described below. These embodiments are shown by way of example, and it goes without saying that various modifications are possible without departing from the technical idea of the present invention.

[0019] In FIGS. 1 to 4, reference numeral 10 denotes a multi-stage vibration feeder for manual sorting according to the present invention.

[0020] The multi-stage vibration feeder 10 for manual sorting is a multi-stage vibration feeder for manual sorting for sorting the sorting object from the waste in which the sorting objects to be sorted are mixed.

[0021] The multi-stage vibration feeder 10 for manual sorting includes a first trough 12 made of metal, an automatic weighing mechanism 14 provided on the first trough 12, a slit plate 16 provided on the first trough 12 and having a plurality of slits formed in the longitudinal direction parallel to the conveyance direction of the waste, and first vibration members 18a and 18b for vibrating the first trough 12, and includes a first vibration feeder section 20.

[0022] The multi-stage vibration feeder 10 for manual sorting also includes a second trough 22 made of metal disposed downstream of the first trough 12, an automatic weighing mechanism 24 provided on the second trough 22, and second vibration members 26a and 26b for vibrating the second trough 22, and includes a second vibration feeder section 28.

[0023] Furthermore, the multi-stage vibration feeder 10 for manual sorting includes a third trough 30 made of metal disposed downstream of the second trough 22, an automatic weighing mechanism 32 provided on the third trough 30, and third vibration members 34a and 34b for vibrating the third trough 30, and includes a third vibration feeder section 36.

[0024] Furthermore, the multi-stage vibration feeder 10 for manual sorting includes a fourth trough 38 made of non-magnetic metal disposed downstream of the third trough 30, an automatic weighing mechanism 40 provided on the fourth trough 38, a magnetic separator (magnetic force separator) 42 for detecting magnetic waste among the waste on the fourth trough 38, and fourth vibration members 44a and 44b for vibrating the fourth trough 38, and includes a fourth vibration feeder section 46.

[0025] The multi-stage vibration feeder 10 for manual sorting causes the first trough 12, the second trough 22, the third trough 30, and the fourth trough 38 to vibrate by the vibration forces of the first vibration members 18a, 18b, the second vibration members 26a, 26b, the third vibration members 34a, 34b, and the fourth vibration members 44a, 44b. Due to this amplitude force, the waste placed on the first vibration feeder section 20, the second vibration feeder section 28, the third vibration feeder section 36, and the fourth vibration feeder section 46 is conveyed from upstream to downstream, that is, from the first trough 12 of the first vibration feeder section 20 toward the fourth trough 38 of the fourth vibration feeder section 46.

[0026] And the conveying speeds of the waste on the first vibration feeder section 20, the second vibration feeder section 28, the third vibration feeder section 36, and the fourth vibration feeder section 46 are the conveying speed of the first vibration feeder section > the conveying speed of the second vibration feeder section > the conveying speed of the third vibration feeder section > the conveying speed of the fourth vibration feeder section,

[0027] Here, as the conveyance speed for conveying the waste of the first vibration feeder unit 20, for example, it can be set to 12 m / min. In this case, as the conveyance speed for conveying the waste of the second vibration feeder unit 28, for example, it is set to 11 m / min. And as the conveyance speed for conveying the waste of the third vibration feeder unit 36, for example, it is set to 9 m / min. Further, as the conveyance speed for conveying the waste of the fourth vibration feeder unit 46, for example, it can be set to 7 m / min. Thus, by reducing the conveyance speed of the vibration feeder unit downstream of the vibration feeder unit upstream when viewed from the conveyance direction, it is possible to optimize the speed at which the manual sorting operator can optimally sort. In the illustrated example, the conveyance speeds for conveying the waste of the first vibration feeder unit 20, the second vibration feeder unit 28, the third vibration feeder unit 36, and the fourth vibration feeder unit 46 are such that the conveyance speed of the first vibration feeder unit > the conveyance speed of the second vibration feeder unit > the conveyance speed of the third vibration feeder unit > the conveyance speed of the fourth vibration feeder unit.

[0028] In the illustrated example, the first vibration members 18a, 18b, the second vibration members 26a, 26b, the third vibration members 34a, 34b, and the fourth vibration members 44a, 44b show an example using a Eurus vibrator. For example, in the case of a Eurus vibrator, to change the vibration force, it is possible to adjust the vibration force by changing the angle of the cam so that the position of the unbalance weight of the Eurus vibrator changes. When the waste in which the sorting objects to be sorted are mixed is heavy, the vibration force can be increased, and when the waste in which the sorting objects to be sorted are mixed is light, the vibration force can be decreased and adjusted. Also, the conveyance speed of the waste can be adjusted by adjusting the vibration force of the vibration members of each vibration feeder unit.

[0029] The multi-stage vibrating feeder 10 for manual sorting, as described above, is configured to include the first vibrating feeder section 20, the second vibrating feeder section 28, the third vibrating feeder section 36, and the fourth vibrating feeder section 46, and the waste is conveyed from the first trough 12 toward the fourth trough 38. Also, the first vibrating feeder section 20, the second vibrating feeder section 28, the third vibrating feeder section 36, and the fourth vibrating feeder section 46 are configured such that the portions of the first trough 12, the second trough 22, the third trough 30, and the fourth trough 38 can move up and down, and each is adjustable in height, so that it can be set to a height at which sorting work is easy.

[0030] In addition, in FIGS. 1 to 4, the symbol W indicates a sorting operator.

[0031] Also, the first vibrating feeder section 20 is provided with sorting boxes 21a and 21b for sorting and storing the sorted objects to be sorted, the second vibrating feeder section 28 is provided with sorting boxes 29a and 29b, the third vibrating feeder section 36 is provided with sorting boxes 37a and 37b, and the fourth vibrating feeder section 46 is provided with sorting boxes 47a and 47b and sorting boxes 49a and 49b, and the objects to be sorted sorted by the sorting operator W are stored. The length from the first vibrating feeder section 20 to the fourth vibrating feeder section 46 can be configured to be about 11 m to 12 m, for example.

[0032] In the illustrated example, an example of a multi-stage vibrating feeder for manual sorting that sorts in a four-stage configuration of the first vibrating feeder section 20, the second vibrating feeder section 28, the third vibrating feeder section 36, and the fourth vibrating feeder section 46 is shown. However, depending on the item to be sorted, an additional vibrating feeder section can be provided, for example, in a six-stage configuration, an eight-stage configuration, or a ten-stage configuration.

[0033] In the illustrated example, an example is shown in which the first vibration feeder unit 20, the second vibration feeder unit 28, the third vibration feeder unit 36, and the fourth vibration feeder unit 46 are connected and arranged in parallel. However, depending on the item to be sorted, an additional vibration feeder unit may be provided in front of the first vibration feeder unit 20, an additional vibration feeder unit may be provided between the first vibration feeder unit 20 and the second vibration feeder unit 28, or an additional vibration feeder unit may be provided between the third vibration feeder unit 36 and the fourth vibration feeder unit 46. That is, it is possible to increase the number of sorted items by increasing the number of installed stages of the vibration feeder units.

[0034] However, since the fourth vibration feeder unit 46 is provided with a non-magnetic metal fourth trough 38 and a magnetic separator 42 for detecting magnetic waste among the waste on the fourth trough 38, as described above, even in the case of a multi-stage vibration feeder for manual sorting having a six-stage configuration, an eight-stage configuration, or a ten-stage configuration, the fourth vibration feeder unit 46 having the magnetic separator 42 is preferably arranged at the most downstream.

[0035] The first vibration feeder unit 20 is fed with waste in which sorting objects to be sorted (for example, waste such as construction waste and resource waste) are mixed, and includes relatively large waste such as blue sheets, paper, or combustibles. In the first vibration feeder unit 20, large sorting objects that do not pass through the slits, such as blue sheets, paper, or combustibles, are sorted on the slit plate 16. Fine-grained products (for example, those of a heavy material system such as earth and sand) that have entered and fallen between the slit plates 16 by vibration are sorted after the third trough and are therefore in the lower layer of the waste and are conveyed on the first trough 12. That is, the heavy material system is conveyed in a state of being accumulated under the mixed waste. Those sorted on the slit plate 16 are sorted by the sorting worker W into sorting boxes 21a and 21b, and the sorting efficiency is improved.

[0036] Fine objects to be sorted, such as sand and glass pieces, passing through the slit plate 16 fall onto the first trough 12 through the slit plate 16 and are conveyed to the second vibrating feeder section 28 while being vibrated.

[0037] In the second vibrating feeder section 28, wood chips and so-called "garbage" such as industrial waste and construction waste materials are sorted by hand. Also, recyclable items such as glass are sorted by hand. The objects to be sorted sorted by the sorting worker W are stored in the sorting boxes 29a and 29b. In the first vibrating feeder section 20 and the second vibrating feeder section 28, mainly waste plastics and combustibles are sorted. In the second vibrating feeder section 28, lightweight items are mainly sorted. Similarly, in the third vibrating feeder section 36, wood chips and so-called "garbage" such as industrial waste and construction waste materials are sorted by hand. Also, recyclable items such as glass are sorted by hand. The objects to be sorted sorted by the sorting worker W are stored in the sorting boxes 37a, 37b, 47a, and 47b.

[0038] In the fourth vibrating feeder section 46, since the magnetic separator 42 is provided, detected iron and the like are sorted. Therefore, the fourth trough 38 is made of a non-magnetic metal. Also, so-called dangerous goods and explosives such as waste oil bottles and cans of thinner, batteries, and cylinders are sorted here. The objects to be sorted sorted by the sorting worker W are stored in the sorting boxes 49a and 49b.

[0039] In this way, manual sorting can be performed in one line. The manual sorting feeders are separated for each sorting item and arranged in multiple stages, and the sorting line is weighed by an automatic weighing mechanism. The automatic weighing mechanism of each vibrating feeder unit can be applied with the automatic weighing mechanism used in known vibrating feeders. Then, as it goes backward along with the weight of the processed items being sorted and decreasing, the vibration force of the vibrating feeders of the third vibrating feeder unit 36 and the fourth vibrating feeder unit 46 is reduced to slow down the speed for conveying. By reducing the conveying speed in this way, in particular, the sorting efficiency and the ability to prevent disasters and ensure safety of contraband items such as button batteries that are small and difficult to remove by the magnetic separator 42 can be improved.

[0040] Also, as shown in FIG. 1, when the sorting operator W performs sorting on one side, a trough for one side is used. The fourth trough 38 is a trough for one side. On the trough of the fourth trough 38 which is the trough for one side, a flow plate 50 is provided for the waste to be conveyed biased toward the sorting operator W side of the fourth vibrating feeder unit 46. Thereby, since the waste is biased and flowed toward the sorting operator W side, manual sorting can be performed within the reach of the hand.

[0041] Also, in the first vibrating feeder unit 20 (first stage), since fine-grained products are not sorted, while screening with the slit plate 16, it is dropped onto the first trough 12, and lightweight objects and other objects with a large specific gravity are easily screened and separated in the upper layer of the feeder.

[0042] Conventionally, when a magnetic separator was installed in the sorting line of a belt conveyor, the magnetism of the conveyor was generated and efficient magnetic separation could not be achieved. For this reason, only the fourth vibrating feeder unit 46 where the magnetic separator is installed is made of a non-magnetic material (such as SUS304, 361, etc.), and devices that cannot be achieved in the sorting line of a belt conveyor such as cutting the discharge outlet at the side of the feeder became possible.

[0043] Conventionally, sorting by a belt conveyor has a problem that the belt wears out severely, the belt is easily cut by aggregates containing metal and steel bars, and the running cost burden is large. However, in the multi-stage vibrating feeder for manual sorting of the present invention, since the conveying surface is made of metal, there is an advantage that consumables do not occur within the service life of the equipment.

[0044] Conventional manual sorting lines are sorting lines using belt conveyors, so there is a problem that accidents occur in which sorting workers are caught in rotating objects (rollers) during sorting operations and cleaning operations. In the multi-stage vibrating feeder for manual sorting of the present invention, there are no rotating objects and it is possible to ensure safe processing operations and safe cleaning operations.

[0045] The multi-stage vibrating feeder for manual sorting of the present invention can be suitably used as a multi-stage vibrating feeder for manual sorting for manually sorting objects to be sorted including waste such as construction waste and resource waste.
