However, in the conventional waste container dropping device such as Patent Document 1, the pushing member is in a position where the dust container installation part in front of the charging port is always sandwiched between the charging port and the telescopic cylinder and the connecting member are always in the chute. It was arrange | positioned between the side and the pushing member. That is, since the horizontal circumference of the garbage container installation part was always surrounded in an L shape, it can be installed only in a limited direction when installing the garbage container in the garbage container installation part, and workability is poor. There was a problem.
In addition, when dust spills from the garbage container, the dust comes into contact with the pushing member, causing odor and corrosion, and maintenance is very bad.

Conventionally, separate cylinders (total of three locations) are used for the opening / closing operation of the cover member, the sealing operation after the cover member is closed, and the pushing operation of the pushing member. In order to operate continuously at timing, it is necessary to perform sequence control and speed control. For this reason, there are problems that the number of parts increases and maintainability deteriorates.
Therefore, an object of the present invention is to provide a waste container dropping device capable of improving workability and maintainability and further simplifying the structure.

  In order to achieve the above object, a first invention of the present invention is a chute that is provided in a building and transports a waste container, an inlet provided on a peripheral surface of the chute, and the inlet can be opened and closed.

  And it is provided in the vicinity of the insertion port, and includes a rotating part for pressing that rotates around an axis that does not intersect the chute, and a drive device that rotates the rotating part for pressing, and the pressing member includes An extension part fixed or latched to extend in the rotational radius direction with respect to the pushing rotary part, and a waste container abutting part connected to the tip of the extension part. .

  According to the first aspect of the present invention, the dust container abutting portion of the pushing member is moved from the side of the inlet to the front of the inlet by rotating the pushing rotary portion with the driving device, and the garbage container The contact portion can be moved in the pushing direction of the garbage container. As a result, when the garbage container is installed in the garbage container installation part in front of the inlet, the waste container abutting part of the pushing member can be left in front of the inlet, so the installation direction is not limited, A garbage container can be installed in the garbage container installation section from the periphery of the container installation section in the horizontal direction. Thereby, it can be set as the waste container dropping device excellent in workability | operativity.

In addition, even if garbage is spilled from the garbage container when the garbage container is installed in the garbage container installation part, the dust does not come into contact with the pushing member. Therefore, when the pushing member is pushed, the pushing member and the pushing rotation part It is possible to prevent troubles such as dust becoming entangled between the two and malfunctioning.
Moreover, the odor caused by the entanglement of dust can be prevented, and the corrosion caused thereby can also be prevented.

  Therefore, it is possible to provide a waste container dropping device that is superior in workability and has improved maintainability as compared with the conventional waste container dropping device in which the periphery of the waste container installation portion is always surrounded in an L shape.

  According to a second invention, in the first invention, the pushing rotary part has a substantially circular first outer peripheral part, and the feed opening is viewed from the front and is further away from the throwing inlet than the push rotating part. In this position, a turning rotary part having a substantially circular second outer peripheral part is disposed, and a winding transmission strip is bridged between the first outer peripheral part and the second outer peripheral part, The cover member and the pushing member are attached to the winding transmission strip.

Therefore, the waste container dropping device can be simplified and the maintainability can be improved as compared with the conventional one while having the same function as the conventional one.

According to a third aspect of the present invention, in the second aspect of the present invention, the outer diameter of the second outer peripheral portion of the folding rotating portion is smaller than the outer diameter of the first outer peripheral portion of the pushing rotating portion, The drive device is connected to the rotating shaft of the unit.
According to the third aspect of the present invention, the driving force can be transmitted to the pushing rotary part via the winding transmission by rotating the turning rotary part with the driving device.

  Further, by connecting the rotating shaft of the driving device to the rotating shaft of the folding rotating portion, it is possible to prevent the driving device from being present around the pushing rotating portion in the vicinity of the insertion port. As a result, a larger working space in the vicinity of the charging port can be secured, and a waste container dropping device with excellent workability can be obtained.

  Also, by forming the outer diameter of the turning rotary part smaller than the outer diameter of the pushing rotary part, the turning rotary part is part of a speed reducer that slows the rotational speed of the pushing rotary part and increases the rotational torque. Can be used as Thereby, not only the adjustment of the driving device itself but also the adjustment of the driving force to the pushing member can be performed by exchanging the turning rotary part. As a result, the adjustment range of the driving force of the pushing rotary portion is widened, and the maintainability can be improved.

According to a fourth aspect of the present invention, in the second or third aspect, the pushing rotary part is disposed on a side of the insertion port, and the folding turning part is disposed above the pushing rotary part. ing.
According to the fourth aspect of the invention, in the retracted state of the pushing member, the pushing member can be positioned above the garbage container installation part before the charging port. Thereby, when installing a garbage container in a garbage container installation part, the working space around the horizontal direction of a garbage container installation part can be ensured widely. Further, by retracting the pushing member in the space above the waste container installation part, the space originally provided for installing the waste container is effectively used compared with the case where the pushing member is retracted to the side of the inlet. Workability is improved.

According to a fifth aspect of the present invention based on the fourth aspect of the present invention, the pushing rotary portion is disposed so that a pair of rotation shafts substantially coincide with each other on the left and right sides of the insertion port, and the pushing member includes the left and right pushing portions. A pair of extending portions provided respectively corresponding to the rotating portions for use, and the waste container abutting portion provided continuously between the pair of extending portions.
According to the fifth aspect, since the pushing member is substantially U-shaped and both ends thereof are supported, it is possible to easily ensure the strength of the pushing member and the followability to the garbage container during the pushing operation. Thereby, the shape of the pushing member can be simplified.

According to a sixth aspect of the present invention based on the fifth aspect of the present invention, the pair of turn-around rotating parts are arranged in a pair in the left-right direction of the insertion port so that the rotation axis centers substantially coincide with each other. The left and right rotating parts for pushing are respectively paired, and the left and right rotating parts for folding are connected by a connecting shaft.
According to the sixth aspect of the invention, the pair of left and right pushing rotation parts are not only connected by the pushing member, but the pair of left and right folding turning parts are also connected by the connecting shaft. And the turning rotary part can be reliably linked. As a result, the left and right winding transmission strips spanned between the pushing rotation portion and the folding rotation portion are stably moved, and the cover member and the pushing member attached to the winding transmission strip are stably linked. Can be made. As a result, troubles are reduced and maintainability is improved.

  Further, according to a seventh invention, in any one of the fourth to sixth inventions, between the cover member and the winding transmission strip, the left-right direction of the insertion port is the axial direction of each pivot portion. A four-bar parallel link mechanism is provided, and the cover member is provided with a pressing portion, and the cover member is provided below the charging port from above the charging port. A pressed portion to which the pressing portion is pressed when moved to a position covering the whole is disposed.

After the pressing part provided on the abutment comes into contact with the pressed part, as the mounting part moves downward, the four-bar parallel link mechanism spreads and moves so as to press the cover member against the insertion port. Can do. Thereby, when the cover member is completely closed, the inside of the chute can be sealed. On the contrary, when the mounting part moves upward from the state in which the cover member is completely closed, the four-bar parallel link mechanism is narrowed by the weight of the cover member, and the cover member is moved accordingly. It can be moved away from the inlet. That is, by using the four-bar parallel link mechanism, the cover member can be sealed in the chute and released by driving the transmission gear.

  As a result, it can be performed by a driving device which is one driving source. Accordingly, the structure is simpler than the conventional waste container dropping device that requires a cylinder for the opening / closing operation of the cover member, the sealing operation of the cover member, and the pushing operation of the pushing member, and the waste container having excellent maintainability. It can be a dropping device.

Between the first outer peripheral portion 141 of the pushing rotary portion 14, the outer peripheral portion of the intermediate rotary portion 21, and the second outer peripheral portion 151 of the turning rotary portion 15 on the left side, a winding transmission strip 13 made of a chain is provided. It is laid over. Also on the right side, between the first outer peripheral part 141 of the pushing rotary part 14, the outer peripheral part of the intermediate rotary part 21, and the second outer peripheral part 151 of the turning rotary part 15, a winding transmission strip made of a chain is also provided. 13 is bridged. The left and right winding transmission strips 13, 13 are endless. The left and right winding transmission strips 13 and 13 are driven by driving the driving device 17 to rotate the left and right turning rotary portions 15 and 15. In addition, when the winding transmission strips 13 and 13 are driven, the rotational driving force of the folding rotary portions 15 and 15 is transmitted to the pushing rotary portions 14 and 14 via the winding transmission strips 13 and 13. It will be.
Here, the pushing member 12 and the cover member 11 are attached to the left and right winding transmission strips 13, 13.
The pushing member 12 and the cover member 11 are moved up and down in conjunction with each other by driving the left and right winding transmission strips 13 and 13.

  The pushing member 12 has a pair of extending portions 121 and a pair of left and right pushing rotating portions 14 that are hooked via the winding transmission strip 13 so as to extend in the rotation radius direction. And a waste container abutting portion 122 connected to the tip of the extending portion 121. Thereby, the entire shape of the pushing member 12 forms a substantially U-shape. In addition, the rotation radial direction which has attached the pushing member 12 here means the radial direction from the center of the rotation part 14 for pushing, or a direction close | similar to it.

  Further, the left and right end portions of the extending portion 121 of the push-in member 12 are respectively bifurcated and formed so as to be substantially Y-shaped. This bifurcated end is attached to the pushing member attaching part 131 fixed to the winding transmission strip 13 with bolts and nuts. Thus, the following effect is acquired by attaching the pushing member 12 to the pushing member attaching part 131 in two steps. That is, the pushing member 12 can have sufficient strength so as not to be deformed even if the garbage container 2 is heavier than the case where it is not bifurcated.

  Further, the cover member 11 is formed so as to match the shape of the rectangular insertion port 10 in front view and to match the curved shape of the peripheral surface of the chute 3. The cover member 11 is configured such that when sealed, the inner surface of the cover member 11 is smoothly continuous with the surrounding surface. A packing 113 (see FIG. 3) is attached to the outer peripheral edge on the inner surface side of the cover member 11 so as to improve the airtightness in the chute 3 when sealed.

  A rectangular frame-like cover frame 111 is fixed to the outer surface (front surface) side of the cover member 11. Upper and lower cover member guide rollers 112b and 112b are rotatably attached to the left and right side surfaces of the cover frame 111 (see FIGS. 3 and 4B). The upper and lower cover member guide rollers 112b and 112b are attached to the cover frame 111 so as to match the vertical distance between the upper protruding rail portion 191d and the lower protruding rail portion 191e of the cover member guide rail portion 191b. The upper and lower cover member guide rollers 112b and 112b are fitted to the cover member guide rail portion 191b. Thereby, the cover member 11 can be smoothly moved up and down while basically restricting movement in the front-rear direction.

However, when the cover member 11 is moved downward and the lower guide roller 112b is brought into contact with the lower protruding rail portion 191e, the upper guide roller 112b is arranged at the height position of the upper protruding rail portion 191d. Is done. At this time, the cover member 11 is movable in a direction (rearward) approaching the insertion port 10 along the upper and lower guide rollers 112b and 112b along the upper protruding rail portion 191d and the lower protruding rail portion 191e.
A four-bar parallel link mechanism 18 is interposed between the cover frame 111 of the cover member 11 and the winding transmission strip 13.

This four-joint parallel link mechanism 18 has the left-right direction of the insertion port 10 as the axial direction of each pivotal portion, and is provided in a pair of left and right corresponding to the left and right winding transmission strips 13, 13. .
6 and 7 show an operation diagram of the four-bar parallel link mechanism 18.

  As shown in FIG. 2 and FIG. 6A, each four-node parallel link mechanism 18 includes a plate-like upper L-shaped link 181 whose one end is pivotally connected to the upper portion of the cover frame 111, and an upper L-shaped link 181. A bar-like upper and lower connecting frame 182 whose upper end is pivotally connected to the other end, and a plate-like lower L-shaped link whose one end is pivotally connected to the lower end of the upper and lower connecting frame 182 and the other end is pivotally connected to the lower part of the cover frame 111 183.

The pair of left and right upper and lower connecting frames 182 and 182 are connected by a left and right connecting frame 184 so as to be interlocked.
The left and right upper and lower connection frames 182 and 182 are connected to the left and right winding transmission strips 13 and 13 by L-shaped attachment portions 185, respectively.

As shown in FIGS. 3 and 7B, the left and right upper and lower connecting frames 182 and 182 are provided with two roller bases 186 so as to face the link guide rail portions 191a, respectively. The base 186 is provided with a link guide roller 112a fitted to the link guide rail portion 191a.
As a result, the left and right upper and lower connecting frames 182 and 182 can smoothly move up and down while being restricted from moving back and forth.

  As described above, the upper and lower connecting frames 182 and 182 of the four-joint parallel link mechanisms 18 and 18 are restricted from moving in the front-rear direction, so that only the vertical direction is accompanied by the driving of the winding transmission strips 13 and 13. Is configured to move. Further, since the cover member 11 is connected to the upper and lower connection frames 182 and 182 via the upper L-shaped links 181 and 181 and the lower L-shaped links 183 and 183, the cover member 11 is driven along with the driving of the winding transmission strips 13 and 13. Are configured to move up and down. When the upper and lower connection frames 182 and 182 and the cover member 11 are moved up and down integrally, the cover member 11 is moved by its own weight to the upper and lower connection frames 182 and 182 to the upper L-shaped links 181 and 181 and the lower L-shaped links. It becomes the form suspended via 183,183. Further, in this case, the interval between the cover member 11 and the upper and lower connecting frames 182 and 182 is configured to be narrowed in accordance with the interval between the cover member guide rail portion 191b and the link guide rail portion 191a.

On the other hand, when the upper and lower connecting frames 182 and 182 are moved downward in a state where the lower cover member guide rollers 112b and 112b are pressed against the lower protruding rail portion 191e, the cover member 111 includes the cover member 11 and the upper and lower frames. A force to increase the distance between the connecting frames 182 and 182 is applied. That is, the lower cover member guide roller 112 b functions as the pressing portion 22, and the lower protruding rail portion 191 e functions as the pressed portion 19.
With such a configuration, the cover member 11 is configured to be pressed against the chute 3 when being closed, and the inside of the chute 3 is sealed.

  Next, as shown in FIG. 2 and FIG. 5B, a roller conveyor 101 extending from the outer peripheral surface of the chute 3 is provided at a height position near the lower edge of the insertion port 10. On this roller conveyor 101, it is a waste container installation part when driving the cover member 11 and the pushing member 12. FIG.

The roller conveyor 101 reduces the resistance when the pushing member 12 pushes the garbage container 2. In this embodiment, since the waste container 2 is pushed into the chute 3 by the pushing member 12, no power is required for the roller conveyor 101 itself. The rollers of the roller conveyor 101 have, for example, a rotating structure using a bearing.
The garbage container installation part may be a plate-like resin with good sliding property.
Further, a garbage container support device 20 is provided in the vicinity of the lower edge of the inlet 10.
The garbage container support device 20 has a pair of left and right support arms 201 and 201 that can be opened and closed temporarily to support the garbage container 2 when it is moved into the chute 3.
The pair of support arms 201 and 201 are respectively stored in storage portions 204 and 204 that are provided in a concave shape on the inner peripheral surface of the chute 3 just below the insertion port 10 and at a position facing it. The storage portions 204 and 204 are formed so as to protrude from the outer peripheral surface of the chute 3.

  The support arm 201 includes a rotation shaft portion 211 and a pair of support roller portions 212 and 212 extending in the rotation radius direction with respect to the rotation shaft portion 211, and is formed in a substantially bowl shape. The rotation shaft portion 211 is supported on the inner wall surface forming the storage portion 204 so that the height position thereof substantially coincides with the height position of the roller conveyor 101. Moreover, the rotating shaft part 211 is rotatable around an axis in the horizontal direction (left-right direction) orthogonal to the pushing direction (front-rear direction) of the garbage container 2. The rotating shaft 211 is provided through a side wall facing the horizontal direction (left-right direction) of the storage portion 204 provided so as to protrude from the chute 3 when viewed from the outside.

  Further, the support roller portion 212 can be switched between a support state protruding from the inner peripheral surface of the chute 3 and a storage state submerged relative to the inner peripheral surface of the chute 3 as the rotating shaft portion 211 rotates. Yes. In the support state, the support roller portion 212 extends in the horizontal direction from the rotation shaft portion 211.

A plurality of rollers 222 are arranged in the support roller unit 212. This roller 222 improves the slipping of the waste container 2 and reduces friction when the pushing member 12 pushes the waste container 2 or when the support roller unit 212 is stored and the dust container 2 is dropped. .
The end of the rotating shaft 211 is outside the chute 3, but the support roller 212 is inside the chute 3 in the supported state.

  In addition, a linear link member 202 is pivotally connected to the rotation shaft portions of the pair of support arms 201 and 201 via a bracket outside the chute 3. Further, the other ends of the pair of linear link members 202 are connected to both horizontal ends of the upper end of the T-type link member 203. The vertical portion of the T-shaped link member 203 is guided by the guide member 206 so that the T-shaped link member 203 can move only in the vertical direction (vertical direction).

  Further, an air cylinder 205 as a driving device is attached to the T-type link member 203. The air cylinder 205 is attached at a position offset from the center of the T-shaped link member 203. Thus, the air cylinder 205 is configured not to obstruct the opening of the cover member 11.

The reason why the above-described T-shaped link member 203 is provided is that the stroke of the air cylinder 205 can be made shorter than when the linear link member 202 is operated up and down.
The operation of this embodiment will be described with reference to FIGS. 2, 4 and 5. FIG.
First, a description will be given of a large operation when the garbage container 2 is charged.

  As shown to Fig.4 (a), the garbage container 2 is mounted on the roller conveyor 101 as a garbage container installation part. Then, a sensor (not shown) detects that the garbage container 2 is installed. Thereafter, after an automatic charging control device (not shown) confirms that there is no other waste container 2 in the chute 3, the waste container support device 20 is in a support state (see FIG. 2).

  Next, as shown in FIG. 4B, when the driving device 17 (see FIG. 2) is driven to open the cover member 11 and the winding transmission strip 13 starts to move, The attached cover member 11 starts to open, and at the same time, the pushing member 12 starts to operate.

  Thereafter, as shown in FIG. 5A, as the cover member 11 rises toward the turning-back rotating portions 15, 15, the pushing member 12 descends, and the middle of the vertical height of the outer peripheral surface of the garbage container 2 is increased. Abut.

  Finally, as shown in FIG. 5B, when the cover member 11 is in the upper part where the insertion port 10 is completely opened and is fully raised, the pushing member 12 pushes the garbage container 2 into the chute 3 completely. At that time, the garbage container 2 is supported by the pair of support arms 201 and 201 of the garbage container support device 20 and does not fall. Thereafter, while the garbage container 2 is supported by the support arms 201, 201, the cover member 11 is slid and closed along the chute circumferential surface to seal the inside of the chute 3. At that time, the support arms 201 and 201 of the garbage container support device 20 are immersed in the storage unit 204 to be stored, and the garbage container 2 supported thereby falls.

Next, the operation of the four-bar parallel link mechanism 18 when the cover member 11 is opened from the sealed state will be described with reference to FIGS.
From the sealed state in which the inner surface of the cover member 11 is smoothly continuous with the surrounding surface (see FIG. 6A), the winding transmission 13 is driven by the rotation of the driving device 17, and the four-bar parallel link When the upper and lower connecting frames 182 of the mechanism 18 are pulled upward, the cover member 11 starts to open. Specifically, as the upper and lower connecting frame 182 moves upward, the upper L-link 181 and the lower L-shaped link 183 and the upper and lower connecting frames 182 also move upward. At this time, the upper and lower cover member guide rollers 112b and 112b attached to the cover frame 111 are positioned in the upper protruding rail portion 191d and the lower protruding rail portion 191e of the cover member guide rail portion 191b, respectively, and move up and down. Is regulated.
As a result, the upper L-shaped link 181 and the lower L-shaped link 183 are forced to rotate counterclockwise in FIG. 6A without changing the vertical height of the pivotal portion with the cover member 11. Work. As a result, a force for opening the cover member 11 forward is applied.

As shown in FIG. 6B, the link guide rollers 112a and 112a and the cover member guide rollers 112b and 112b are respectively fitted with the upper and lower connecting frames 182 as they move upward. The operation starts along the rails of the rail portion 191a and the cover member guide rail portion 191b.
The link guide rollers 112a and 112a operate vertically upward, while the cover member guide rollers 112b and 112b move along the lower protruding rail portion 191e and the upper protruding rail portion 191d that function as pressed portions. It moves in a direction away from the inlet 10 (forward direction).
At that time, in the four-bar parallel link mechanism 18, the upper L-shaped links 181, 181 and the lower L-shaped links 183, 183 are pivoted counterclockwise in FIG. It rotates around the joint and operates so as to reduce the distance between the cover member 11 and the upper and lower connecting frames 182 and 182.

  When the opening operation of the cover member 11 is continued, the link guide rollers 112a and 112a further move vertically upward as the upper and lower connecting frame 182 moves vertically upward as shown in FIG. 7A. Then, the cover member guide rollers 112b and 112b that are detaching the upper protruding rail portion 191d and the lower protruding rail portion 191e are curved connection portions between the upper protruding rail portion 191d and the lower protruding rail portion 191e and the rail main body portion 191c. It operates diagonally upward along. That is, the movement of the cover member 11 moving forward changes from a horizontal movement to a diagonally upward movement.

As shown in FIG. 7B, finally, the four-bar parallel link mechanism 18 is narrowed to the maximum, and both the link guide rollers 112a and 112a and the cover member guide rollers 112b and 112b are linked guide rails. Ascending vertically upward along the portion 191a and the guide rail portion 191b for the cover member (rail body portion 191c). As a result, the cover member 11 rises vertically upward and the insertion port 10 appears, resulting in opening.
If the cover member 11 does not operate so as to reduce the distance between the upper and lower connecting frames 182, the cover member 11 is opened while the cover member 11 is pressed against the chute 3. Further, the cover member 11 and the chute 3 are rubbed and worn, and the resistance is large and the energy required for the drive device 17 is increased, resulting in an increase in the size of the device.

Next, operation | movement about the garbage container support apparatus 20 is demonstrated.
As shown in FIG. 5B, the garbage container 2 is pushed into the chute 3 and supported by a pair of support arms 201, 201 of the garbage container support device 20.
Then, the cover member 11 is lowered by the driving device 17 and the cover member 11 and the chute 3 are sealed.
Thereafter, the air cylinder 205 extends to lower the T-shaped link member 203 along the guide member 206, and accordingly, the pair of linear link members 202, 202 rotate downward. When the linear link members 202 and 202 rotate downward, the rotation shaft portion 211 of the support arm 201 rotates, and the pair of support roller portions 212 and 212 extending in the rotational radius direction with respect to the rotation shaft portion 211 are moved downward. Rotate to.

  When the pair of support roller portions 212 and 212 are rotated downward, the pair of support roller portions 212 and 212 are accommodated in the accommodating portion 204, and there is no portion protruding on the inner surface of the chute 3, so Then, the garbage container 2 falls in the chute 3.
