Description

RUBBISH ACCUMULATION DEVICE
The present invention relates to a rubbish accumulation device for compressing and accumulating rubbish.
PTL 1 discloses a rubbish accumulation device including a drum and a cover plate. One of two ends of the drum is closed (referred to below as a closed end) and the other of the two ends of the drum is open (referred to below as an open end). An opening at the open end of the drum is blocked by the cover plate. The cover plate has a discharge outlet therein.
Forward rotation of the drum causes rubbish to move toward the closed end of the drum. As a result, the rubbish is compressed. On the other hand, reverse rotation of the drum causes rubbish to move toward the open end of the drum. As a result, the rubbish is discharged from the discharge outlet. The discharge outlet is located at a position that, relative to the center of a lower part of the drum, is shifted in a reverse rotation direction of the drum. Such positioning of the discharge outlet enables favorable rubbish discharge efficiency. Rubbish discharge efficiency indicates an amount of rubbish that is discharged per unit time.

(First Embodiment)
FIG. 1 is a perspective view illustrating a rear side of a rubbish accumulation device 1 according to a first embodiment of the present invention. FIG. 2 is a perspective view illustrating a front side of the rubbish accumulation device 1. FIG. 3 is a side view illustrating the rubbish accumulation device 1.
As illustrated in FIGS. 1-3, the rubbish accumulation device 1 includes a main body 1A, four load detectors 1B, and a support 1C. The main body 1A compresses and accumulates rubbish. The main body 1A is supported by the support 1C through the load detectors 1B. The support 1C is for example a stand. The four load detectors 1B are located on an upper part of the support 1C such as to be arranged at four corners of a rectangle. Each of the load detectors 1B is for example a load cell. The four load detectors 1B detect the weight of the main body 1A. Therefore, the weight of rubbish accumulated in the main body 1A can be detected by subtracting the weight of the main body 1A when no rubbish is accumulated therein from the weight of the main body 1A when the rubbish is accumulated therein.
The main body 1A includes a drum 2, a loading-side blocking section 3 having a loading inlet 3a therein, a discharge-side blocking section 4 having a discharge outlet 4a therein, a loading guide 5, a discharge-side cover 6, a discharge guide 7, and a frame F. The frame F is located such as to enclose the drum 2. The four load detectors 1B are located between the upper part of the support 1C and a lower part of the frame F.
The drum 2 is supported by the frame F in a rotatable manner. Rubbish is loaded into the drum 2. The drum 2 has a hollow cylindrical shape and has an internal diameter that is approximately uniform in a direction along a rotational axis of the drum 2. Both ends of the drum 2 are open. The drum 2 rotates in a specific direction. In the first embodiment, the drum 2 rotates in a predetermined rotation direction R1. The rotation direction R1 corresponds to clockwise when the main body 1A is viewed from the front side thereof.
A ring-shaped contact section 2a and a ring-shaped contact section 2b are each located on an outer circumferential surface of the drum. The main body 1A also includes four rollers 9 and two rotation guides 10 for causing rotation of the drum 2.
The contact section 2a protrudes from the outer circumferential surface of the drum 2. The contact section 2a is located on a region of the outer circumferential surface of the drum 2 that is closer to the loading inlet 3a than to the discharge outlet 4a. The contact section 2b also protrudes from the outer circumferential surface of the drum 2. The contact section 2b is located on a region of the outer circumferential surface of the drum 2 that is closer to the discharge outlet 4a than to the loading inlet 3a.
The four rollers 9 are located on the lower part of the frame F such as to be arranged at four corners of a rectangle. Among the four rollers 9, two of the rollers 9 are arranged on a straight line in correspondence with the contact section 2a and the other two of the rollers 9 are arranged on a straight line in correspondence with the contact section 2b. Each of the rollers 9 is supported by the lower part of the frame F in a rotatable manner. Each of the rollers 9 is rotatable about a rotational axis that is parallel to the rotational axis of the drum 2. In the first embodiment, the rotational axis of the drum 2 is approximately parallel to the X axis.
The two rotation guides 10 are located on a straight line in correspondence with the contact section 2b on the lower part of the frame F. In such a configuration, the two rotation guides 10 are located between the two rollers 9 corresponding to the contact section 2b in terms of location. Each of the rotation guides 10 includes a pair of rollers 23 that are located with a gap therebetween. Each of the rollers 23 is supported by the lower part of the frame F in a rotatable manner. Each of the rollers 23 is rotatable about a rotational axis that is approximately perpendicular to the outer circumferential surface of the drum 2.
The drum 2 is mounted on the four rollers 9 such that the contact section 2a is in contact with the two rollers 9 corresponding thereto, the contact section 2b is in contact with the two rollers 9 corresponding thereto, and the contact section 2b is fitted into the gap between the pair of rollers 23 of each of the rotation guides 10. As a result, the drum 2 can rotate in the rotation direction R1 through rotation of the rollers 9. The rotation guides 10 restrict shifting of position of the drum 2 in terms of the direction along the rotational axis of the drum 2. In the first embodiment, the direction along the rotational axis of the drum 2 is approximately parallel to the X axis.
The following explains each element of configuration of the main body 1A with reference to FIGS. 1-3. The discharge-side blocking section 4 is attached to one of two ends of the frame F. The discharge-side blocking section 4 partially blocks an opening at one of two ends of the drum 2. The discharge-side blocking section 4 has a discharge outlet 4a therein for discharge of rubbish from the drum 2. The discharge outlet 4a has an approximately polygonal shape. The discharge-side cover 6 has an approximately rectangular shape and blocks the discharge outlet 4a. The discharge guide 7 is connected to the discharge-side blocking section 4 and when rubbish is discharged from the discharge outlet 4a, the discharge guide 7 guides the rubbish externally to the rubbish accumulation device 1. The discharge guide 7 for example guides the rubbish to a loading inlet of a rubbish collection vehicle.
The loading-side blocking section 3 is attached to the other of the two ends of the frame F. The loading-side blocking section 3 partially blocks an opening at the other of the two ends of the drum 2. The loading-side blocking section 3 has a loading inlet 3a therein for loading of rubbish into the drum 2.
The loading guide 5 is connected to the loading-side blocking section 3 and guides rubbish to the loading inlet 3a. The loading guide 5 has an upper surface that is open and a lower surface that is inclined. The loading guide 5 is for example connected to a rubbish chute and when rubbish falls along the rubbish chute, the loading guide 5 guides the rubbish to the loading inlet 3a.
The following explains movement of the discharge-side cover 6 with reference to FIGS. 2 and 4. FIG. 4 is a front view of the rubbish accumulation device 1. As illustrated in FIGS. 2 and 4, the discharge-side cover 6 moves between a closed position at which the discharge-side cover 6 blocks the discharge outlet 4a and an open position at which the discharge-side cover 6 exposes the discharge outlet 4a. In FIG. 4, the discharge-side cover 6 as positioned at the closed position is indicated by a solid line and the discharge-side cover 6 as positioned at the open position is indicated by a long dashed double-short dashed line. In the first embodiment, the discharge-side cover 6 moves between the closed position and the open position by moving along the discharge outlet 4a. The following explains movement of the discharge-side cover 6 in detail.
As illustrated in FIGS. 2 and 4, the main body 1A further includes two opening-closing guides 11, a reinforcing member 12, a lower limit sensor 13, and an upper limit sensor 14. The discharge-side cover 6 includes two guided members 6a corresponding to the two opening-closing guides 11, a detection target 6L, and a detection target 6U.
The guided members 6a each have an approximately square cylindrical shape and are located on side surfaces of the discharge-side cover 6. Each of the guided members 6a is orientated longitudinally in an approximately vertical direction and extends from the bottom of a corresponding side edge of the discharge-side cover 6 to the top of the corresponding side edge of the discharge-side cover 6. The detection target 6L is located on one of the two guided members 6a in correspondence with the lower limit sensor 13. The detection target 6L is located at approximately the same height as the top of the corresponding side edge of the discharge-side cover 6. The detection target 6U is located on the other of the two guided members 6a in correspondence with the upper limit sensor 14. The detection target 6U is located at a lower height than the detection target 6L. Also, the detection target 6U is located at a higher height than a central part of the corresponding side edge of the discharge-side cover 6 in terms of a longitudinal direction of the corresponding side edge and is located at a lower height than the top of the corresponding side edge of the discharge-side cover 6. Note that the height of each of the detection target 6L and the detection target 6U in the above explanation is a height relative to the bottom of the corresponding side edge of the discharge-side cover 6.
The two opening-closing guides 11 are approximately parallel to one another and are attached to the frame F such as to be located at opposite sides of the discharge outlet 4a. Each of the opening-closing guides 11 has an approximately U-shaped cross-section. Each of the opening-closing guides 11 extends in an approximately vertical direction such that relative to the discharge-side cover 6 at the closed position, the opening-closing guide 11 extends from a position at the bottom of the corresponding side edge of the discharge-side cover 6 to a position further upward than the top of the corresponding side edge of the discharge-side cover 6. The guided members 6a of the discharge-side cover 6 engage respectively with the opening-closing guides 11. Therefore, the discharge-side cover 6 moves between the closed position and the open position by moving along the two opening-closing guides 11. The reinforcing member 12 connects an upper end of one of the two opening-closing guides 11 to an upper end of the other of the two opening-closing guides 11. As a result, the reinforcing member 12 reinforces the two opening-closing guides 11.
The lower limit sensor 13 is attached to one of the opening-closing guides 11 in correspondence with the detection target 6L. The lower limit sensor 13 is located at approximately the same height as the top of the corresponding side edge of the discharge-side cover 6. The upper limit sensor 14 is attached to the other of the opening-closing guides 11 in correspondence with the detection target 6U. The upper limit sensor 14 is located at a higher height than the lower limit sensor 13. In the first embodiment, the lower limit sensor 13 and the upper limit sensor 14 are each a limit switch having an actuator. Note that the height of each of the lower limit sensor 13 and the upper limit sensor 14 explained above is a height relative to the height of the bottom of the corresponding side edge of the discharge-side cover 6 when the discharge-side cover 6 is positioned at the closed position.
The discharge-side cover 6 moves in a vertical upward direction UD from the closed position. The discharge-side cover 6 is stopped at the open position in response to detection of the detection target 6U by the upper limit sensor 14. Note that in the first embodiment, the detection target 6U is detected when the detection target 6U pushes the actuator of the upper limit sensor 14 upward, thereby turning on the upper limit sensor 14. The discharge-side cover 6 also moves in a vertical downward direction LD from the open position. The discharge-side cover 6 is stopped at the closed position in response to detection of the detection target 6L by the lower limit sensor 13. Note that in the first embodiment, the detection target 6L is detected when the detection target 6L pushes the actuator of the lower limit sensor 13 downward, thereby turning on the lower limit sensor 13.
The following explains driving of the discharge-side cover 6 with reference to FIGS. 4-6. FIG. 5 is a perspective view illustrating a rear side of the discharge-side cover 6. FIG. 6 illustrates the discharge-side cover 6 and a cover drive section 41 as viewed from above. As illustrated in FIGS. 4-6, the main body 1A further includes the cover drive section 41. The cover drive section 41 causes the discharge-side cover 6 to move between the closed position and the open position by moving the discharge-side cover 6 along the opening-closing guides 11. As illustrated in FIG. 6, the guided members 6a of the discharge-side cover 6 engage with the opening-closing guides 11.
The cover drive section 41 includes a sprocket unit 42 and a drive unit 45. The sprocket unit 42 includes a shaft 43 and two first sprockets 44 that are fixed to opposite ends of the shaft 43. The drive unit 45 includes a first motor 46 that causes the sprocket unit 42 to rotate and a gear section 47 having a plurality of gears. Driving force of the first motor 46 is transmitted to the sprocket unit 42 via the gear section 47.
The discharge-side cover 6 has two linear meshing sections 6b on a rear surface thereof that are located in correspondence with the two first sprockets 44 and that are orientated along the two opening-closing guides 11. Each of the meshing sections 6b is a chain (for example, a roller chain). In another example of configuration, each of the meshing sections 6b may be a rack. Each of the first sprockets 44 meshes with a corresponding one of the meshing sections 6b.
The discharge-side cover 6 is driven by the cover drive section 41 as explained below. The first motor 46 can cause the sprocket unit 42 to rotate in a rotation direction RU through the gear section 47. As a result, the first sprockets 44 meshing with the meshing sections 6b cause the discharge-side cover 6 to move in the vertical upward direction UD. The first motor 46 stops upon detection of the detection target 6U by the upper limit sensor 14, thereby stopping the discharge-side cover 6 at the open position. On the other hand, the first motor 46 can also cause the sprocket unit 42 to rotate in a rotation direction RL through the gear section 47. As a result, the first sprockets 44 cause the discharge-side cover 6 to move in the vertical downward direction LD. The first motor 46 stops upon detection of the detection target 6L by the lower limit sensor 13, thereby stopping the discharge-side cover 6 at the closed position.
The following explains positioning of the discharge-side cover 6 with reference to FIG. 7. FIG. 7 illustrates positioning of the discharge-side cover 6. In FIG. 7, the main body 1A is illustrated as viewed from the front side thereof. The discharge-side cover 6, the discharge-side blocking section 4, and the discharge outlet 4a are each indicated by a long dashed double-short dashed line in FIG. 7 in order to facilitate explanation.
As illustrated in FIG. 7, the discharge-side cover 6 is positioned in correspondence with the discharge outlet 4a. The discharge outlet 4a is located at a position that, relative to a rotational axis AX of the drum 2, is shifted toward a side at which the outer circumferential surface of the drum 2 rotates in a diagonal upward direction (curved upward direction) from a lowest part ML of the drum 2. More specifically, the discharge outlet 4a is located at a position that, relative to the rotational axis AX of the drum 2, is shifted toward a part 50a of the outer circumferential surface of the drum 2 at which the outer circumferential surface rotates in the diagonal upward direction (curved upward direction) from the lowest part ML of the drum 2. Therefore, favorable rubbish discharge efficiency from the discharge outlet 4a is achieved. Rubbish discharge efficiency indicates an amount of rubbish that is discharged per unit time.
The following explains driving of the drum 2 with reference to FIGS. 7 and 8. FIG. 7 illustrates positioning of a drum drive section 38. FIG. 8 is a perspective view illustrating the drum drive section 38. Although FIG. 8 illustrates the rear side of the rubbish accumulation device 1, the loading guide 5 is omitted in order to facilitate explanation. As illustrated in FIGS. 7 and 8, the main body 1A further includes a chain 8, a ring-shaped second sprocket 71, and the drum drive section 38. The chain 8 is for example a rotary chain. The second sprocket 71 is located on the outer circumferential surface of the drum 2 such as to protrude from the outer circumferential surface of the drum 2. The second sprocket 71 is located between the contact section 2a and the contact section 2b on a region of the outer circumferential surface of the drum 2 that is closer to the loading inlet 3a than the discharge outlet 4a. The second sprocket 71 meshes with the chain 8.
The drum drive section 38 causes the drum 2 to rotate. The drum drive section 38 includes a third sprocket 72 and a second motor 49. The third sprocket 72 meshes with the chain 8. The chain 8 is wound against the second sprocket 71 and the third sprocket 72. The second motor 49 is located below the drum 2 at a side at which the outer circumferential surface of the drum 2 rotates in a diagonal downward direction (curved downward direction) toward the lowest part ML of the drum 2. More specifically, the second motor 49 is located below a part 50b of the outer circumferential surface of the drum 2 at which the outer circumferential surface rotates in the diagonal downward direction (curved downward direction) toward the lowest part ML of the drum 2. Therefore, slackening of the chain 8 upon driving of the second motor 49 can be inhibited.
Driving force of the second motor 49 is transmitted to the drum 2 via the third sprocket 72, the chain 8, and the second sprocket 71, thereby causing rotation of the drum 2. More specifically, the second motor 49 causes the third sprocket 72 to rotate in a specific rotation direction R2. As a result, the chain 8 circulates, thereby causing rotation of the drum 2 through the second sprocket 71. The rotation direction R2 is the same as the rotation direction R1.
Before explaining internal structure of the drum 2, the following explains an operation section 15 for operating the drum 2 with reference to FIG. 8. As illustrated in FIG. 8, the main body 1A further includes the operation section 15. The operation section 15 includes a power supply switch 33, a rotation switch 34, a stop switch 35, an open switch 36, and a close switch 37. When the power supply switch 33 is turned on by turning a key, a power supply voltage is supplied to the main body 1A. When the rotation switch 34 is pressed, the drum 2 rotates in the rotation direction R1. When the stop switch 35 is pressed, the drum 2 stops. When the open switch 36 is pressed, the discharge-side cover 6 (refer to FIG. 4) moves to the open position, and when the close switch 37 is pressed, the discharge-side cover 6 moves to the closed position.
The following explains the internal structure of the drum 2 with reference to FIGS. 3, 8, and 9. FIG. 9 is a perspective view illustrating the internal structure of the drum 2. The discharge-side blocking section 4 and the loading-side blocking section 3 are omitted in FIG. 9 in order to facilitate explanation. Therefore, an opening OP1 at one end of the drum 2 and an opening OP2 at the other end of the drum 2 are illustrated.
As illustrated in FIGS. 3, 8, and 9, the main body 1A further includes an internal guide 21. The internal guide 21 is located inside of the drum 2 and is attached to the loading-side blocking section 3 such as to cover the loading inlet 3a from inside of the drum 2. The internal guide 21 protrudes diagonally downward from the loading-side blocking section 3. A lower part of the internal guide 21 is open. Therefore, when rubbish is loaded through the loading inlet 3a, the internal guide 21 guides the rubbish onto an internal surface of a lower part of the drum 2. The internal guide 21 also inhibits rubbish that has been loaded into the drum from being scattered externally from the drum 2 due to being pushed back through the loading inlet 3a.
As illustrated in FIGS. 8 and 9, the internal guide 21 includes a fragmenting section 21a. The fragmenting section 21a is located on a lower part of one of two side surface sections of the internal guide 21. The side surface section on which the fragmenting section 21a is located is opposite to a part of an inner circumferential surface of the drum 2 at which the inner circumferential surface rotates in a downward direction from an uppermost part of the drum 2. Four blade members 22 are located on the inner circumferential surface of the drum 2. Therefore, when the drum 2 rotates about the rotational axis AX in the rotation direction R1, rubbish loaded through the loading inlet 3a becomes caught between the blade members 22 and the fragmenting section 21a, causing fragmentation or crushing of the rubbish.
Each of the blade members 22 has a slightly curved elongated shape. The four blade members 22 are arranged at uniform intervals in terms of a circumferential direction of the drum 2. Each of the blade members 22 is inclined by a specific angle relative to the rotational axis AX of the drum 2. Therefore, when the drum 2 rotates around the rotational axis AX in the rotation direction R1, rubbish is moved toward the discharge-side blocking section 4 from the loading-side blocking section 3 (in other words, in a direction GD) and is pressed against the discharge-side blocking section 4 and the discharge-side cover 6 (FIG. 1) by the blade members 22. As a result, the rubbish is compressed and accumulated.
When rubbish accumulated in the drum 2 is to be discharged, the discharge-side cover 6 is moved to the open position, thereby exposing the discharge outlet 4a (FIG. 4). When the drum 2 then rotates around the rotational axis AX in the rotation direction R1, the blade members 22 discharge the rubbish externally from the drum 2 through the discharge outlet 4a. The rotation direction R1 of the drum 2 is constant (i.e., does not change) for discharge of the rubbish and for compression of the rubbish, thus enabling smooth discharge of the rubbish.
The following explains electrical configuration of the rubbish accumulation device 1 with reference to FIGS. 5, 8, and 10. FIG. 10 illustrates the electrical configuration of the rubbish accumulation device 1. As illustrated in FIG. 10, the rubbish accumulation device 1 includes a micro controller unit (MCU) 51, a power supply circuit 52, a first motor driver 53, and a second motor driver 54 (motor driver). Upon the power supply switch 33 being turned on, the power supply circuit 52 supplies a power supply voltage Vcc to the MCU 51, the operation section 15, the first motor driver 53, the second motor driver 54, the lower limit sensor 13, and the upper limit sensor 14.
As illustrated in FIGS. 5 and 10, upon an ON-signal being input from the open switch 36, the MCU 51 controls the first motor driver 53 to cause the first motor 46 to rotate such that the sprocket unit 42 rotates in the rotation direction RU. As a result, the discharge-side cover 6 moves in the vertical upward direction UD. Next, upon an ON-signal being input from the upper limit sensor 14, the MCU 51 controls the first motor driver 53 to stop the first motor 46. As a result, the discharge-side cover 6 stops at the open position.
Upon an ON-signal being input from the close switch 37, the MCU 51 controls the first motor driver 53 to cause the first motor 46 to rotate such that the sprocket unit 42 rotates in the rotation direction RL. As a result, the discharge-side cover 6 moves in the vertical downward direction LD. Next, upon an ON-signal being input from the lower limit sensor 13, the MCU 51 controls the first motor driver 53 to stop the first motor 46. As a result, the discharge-side cover 6 stops at the closed position.
As illustrated in FIGS. 8 and 10, upon an ON-signal being input from the rotation switch 34, the MCU 51 controls the second motor driver 54 to cause the second motor 49 to rotate such that the third sprocket 72 rotates in the rotation direction R2. As a result, the drum 2 rotates in the rotation direction R1. During the above, the second motor driver 54 causes the second motor 49 to rotate at a constant rotational speed (revolutions per unit time). Next, upon an ON-signal being input from the stop switch 35, the MCU 51 controls the second motor driver 54 to stop the second motor 49. As a result, the drum 2 is stopped.
As explained above with reference to FIGS. 1-10, the rubbish accumulation device 1 according to the first embodiment enables smooth discharge of rubbish while also enabling favorable rubbish discharge efficiency.
Namely, as explained above with reference to FIG. 7, according to the first embodiment, the discharge outlet 4a is located at a position that is shifted toward a side at which the outer circumferential surface of the drum 2 rotates in the diagonal upward direction from the lowest part ML of the drum 2. Therefore, favorable rubbish discharge efficiency through the discharge outlet 4a is achieved. The reasoning for the above is that rubbish on a lower internal surface of the drum 2 is lifted up in the rotation direction R1 due to rotation of the drum 2 in the rotation direction R1, and thus the lifted up rubbish slides downward and is discharged from the drum 2.
Also, as explained above with reference to FIGS. 8 and 9, according to the first embodiment, the rotation direction R1 of the drum 2 is constant for rubbish compression and for rubbish discharge. Therefore, rubbish moves in approximately the same direction GD during both rubbish compression and rubbish discharge. As a result, rubbish can be smoothly discharged compared to a generic rubbish accumulation device in which the rotation direction of a drum during rubbish compression is switched relative to the rotation direction of the drum during rubbish discharge. Also, according to the first embodiment, occurrence of operational mistakes can be inhibited due to the rotation direction of the drum 2 being constant for rubbish compression and for rubbish discharge, as compared to the generic rubbish accumulation device in which the rotation direction of the drum is switched.
Also, as explained above with reference to FIG. 1, according to the first embodiment, the drum 2 has a hollow cylindrical shape. Therefore, the drum 2 can be manufactured more easily than a drum having a central part with a hollow cylindrical shape and two end parts that are either or both tapered.
Also, according to the first embodiment, the loading guide 5 is provided. Therefore, the rubbish accumulation device 1 can be easily connected to a rubbish chute. As a result, the rubbish accumulation device 1 is well suited to use in a building equipped with a rubbish chute.
Furthermore, as explained above with reference to FIG. 4, according to the first embodiment, the discharge-side cover 6 moves between the closed position and the open position by moving along the discharge outlet 4a. Therefore, the discharge-side cover 6 is restricted from protruding outward from the discharge-side blocking section 4 when positioned at the open position. As a result, compared to a discharge-side cover that opens like a swinging door (for example, like a double door), interference caused by the discharge-side cover 6 to collection of rubbish discharged from the drum 2 is limited. Also, according to the first embodiment, the discharge-side cover 6 moves between the closed position and the open position by moving in an approximately vertical direction. Therefore, compared to a configuration in which a discharge-side cover moves between a closed position and an open position by moving in an approximately horizontal direction, the rubbish accumulation device 1 can be installed in a smaller amount of space in terms of the horizontal direction. As a result, the rubbish accumulation device 1 can be easily installed even in a space of limited size in terms of the horizontal direction.
Also, as explained above with reference to FIG. 5, according to the first embodiment, the opening-closing guides 11 and the cover drive section 41 are provided, thus enabling movement of the discharge-side cover 6 in the approximately vertical direction through a simple configuration.
Also, as explained above with reference to FIG. 7, according to the first embodiment, the second motor 49 is located below the drum 2 at a side at which the outer circumferential surface of the drum 2 rotates in the diagonal downward direction toward the lowest part ML of the drum 2. Therefore, the second motor 49 pulls the chain 8 in an approximately vertical downward direction. As a result, slackening of the chain 8 upon driving of the second motor 49 can be inhibited. More specifically, the second motor 49 is preferably located below a part 50b of the outer circumferential surface such that the chain 8 dangles downward in an approximately vertical direction.
Also, as explained above with reference to FIG. 10, according to the first embodiment, the discharge-side cover 6 can be accurately positioned at the closed position through provision of the lower limit sensor 13. Furthermore, the discharge-side cover 6 can be accurately positioned at the open position through provision of the upper limit sensor 14.
(Modified Example)
The following explains a rubbish accumulation device 1 according to a modified example of the first embodiment with reference to FIGS. 8 and 10. In the modified example, the second motor driver 54 controls rotational speed of the second motor 49. The second motor driver 54 for example includes an inverter. In such a configuration, the inverter controls the rotational speed of the second motor 49 by controlling voltage and frequency driving the second motor 49, through control by the MCU 51.
According to the modified example of the first embodiment, when the second motor 49 is to be driven, the rotational speed of the second motor 49 can be gradually increased from zero and the rotational speed can be maintained constant once the rotational speed has reached a specific speed. As a result, slackening of the chain 8 upon driving of the second motor 49 can be further inhibited. Also, by providing the second motor driver 54 according to the modified example, slackening of the chain 8 upon driving of the second motor 49 can be inhibited even in a configuration in which the second motor 49 is located below the part 50a of the outer circumferential surface of the drum 2 at which the outer circumferential surface rotates in the diagonal upward direction from the lowest part ML of the drum 2.
(Second Embodiment)
The following explains a rubbish accumulation device 1 according to a second embodiment of the present invention with reference to FIGS. 1, 11, and 12. FIG. 11 is a perspective view illustrating a rear side of the rubbish accumulation device 1 during raising of the rubbish accumulation device 1. FIG. 12 is a perspective view illustrating the rear side of the rubbish accumulation device 1 during lowering of the rubbish accumulation device 1.
As illustrated in FIGS. 11 and 12, the rubbish accumulation device 1 according to the second embodiment includes a loading-side cover 63 instead of the loading guide 5 according to the first embodiment, and includes a lift 1D instead of the support 1C according to the first embodiment. The rubbish accumulation device 1 according to the second embodiment is the same as the rubbish accumulation device 1 according to the first embodiment in all other aspects of configuration. The following explanation of the second embodiment focuses on differences compared to the first embodiment.
As illustrated in FIG. 11, the loading-side cover 63 blocks the loading inlet 3a. The loading-side cover 63 moves between a closed position at which the loading-side cover 63 blocks the loading inlet 3a and an open position at which the loading-side cover 63 exposes the loading inlet 3a. In the second embodiment, the loading-side cover 63 moves between the closed position and the open position by rotating around a shaft 63b. The loading-side cover 63 includes a rod-shaped handle 63a at the top thereof. Therefore, a user can hold the handle 63a and cause the loading-side cover 63 to move between the closed position and the open position.
The lift 1D includes a stand part 61 and a leg part 62. Four load detectors 1B are located on an upper surface of the stand part 61. The main body 1A is mounted on the four load detectors 1B. The leg part 62 supports the stand part 61. As a result, the lift 1D supports the main body 1A through the load detectors 1B.
As illustrated in FIGS. 11 and 12, the lift 1D adjusts the position of the main body 1A in an approximately vertical direction. More specifically, the leg part 62 can be raised and lowered in the approximately vertical direction. Therefore, the stand part 61 can be raised by raising the leg part 62 and the stand part 61 can be lowered by lowering the leg part 62. In FIG. 11, the lift 1D is raising the stand part 61 through the leg part 62, thereby raising the main body 1A. On the other hand, in FIG. 12, the lift 1D is lowering the stand part 61 through the leg part 62, thereby lowering the main body 1A.
As explained above with reference to FIGS. 1, 11, and 12, with the exception of the lift 1D and the loading-side cover 63, the rubbish accumulation device 1 according to the second embodiment has the same configuration as the rubbish accumulation device 1 according to the first embodiment. Therefore, the second embodiment enables smooth discharge of rubbish while also enabling favorable rubbish discharge efficiency in the same way as the first embodiment. In addition to the above, the rubbish accumulation device 1 according to the second embodiment also achieves other effects of the rubbish accumulation device 1 according to the first embodiment in the same way.
Also, according to the second embodiment, the loading-side cover 63 is provided. Therefore, a user can easily load rubbish through the loading inlet 3a by moving the loading-side cover 63 to the open position.
Also, according to the second embodiment, the lift 1D that can be raised and lowered is provided. Therefore, the height of the loading inlet 3a and the discharge outlet 4a can be adjusted in accordance with rubbish loading or rubbish collection. Therefore, rubbish loading or rubbish collection can be performed smoothly. The height of each of the loading inlet 3a and the discharge outlet 4a refers to a height thereof from a surface on which the lift 1D is installed. When for example rubbish is to be loaded through the loading inlet 3a, the lift 1D is lowered such that the loading inlet 3a is moved to a lower position in accordance with the height of the user. When for example rubbish is to be collected through the discharge outlet 4a, the lift 1D is raised to a higher position in accordance with the position of an inlet into a rubbish collection vehicle.
Through the above, embodiments of the present invention have been explained with reference to the drawings. However, the present invention is not limited to the embodiments and the present invention can be implemented in various different forms within the intended scope thereof (for example, as explained below in sections (1) to (3)).
