Description

The present invention relates to a storage / discharge device including a rotating drum type storage unit.

Conventionally, storage and discharge equipped with a storage unit that temporarily compresses and stores the processed material such as waste collected in apartment houses and commercial facilities, and appropriately discharges the stored processed material to a garbage truck or the like. The device is known. Inside the reservoir, blade plates arranged spirally along the inner peripheral surface are provided. By rotating the storage unit, the object to be processed is pushed into the depth of the storage unit by the blade plate (feeding blade) and compressed.

In this type of storage / discharge device, a structure for controlling the flow and movement of the object to be processed inside the storage unit may be installed in the vicinity of the input port. For example, Patent Document 1 describes a dust storage device in which a semi-cylindrical insertion portion is fixed in the vicinity of an input port of a rotary drum for storing dust.
The insertion portion is arranged so that the central axis is eccentric with respect to the center of the rotating drum in the traveling direction of the dust. Further, regarding the radial gap between the peripheral surface of the insertion portion and the inner peripheral surface of the rotating drum, the gap on the front side of rotation (downstream side of rotation from the insertion port) is on the rear side in the rotation direction (rotation from the insertion port). It is set to be narrower than the gap (on the upstream side of the above) (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2010-083621

However, when the gap on the front side in the rotation direction is set to be narrow, when the object to be processed is almost full, the object to be processed sent to the front side having a narrow gap is likely to be clogged in the gap and easily deposited. As a result, there is a problem that the object to be processed that cannot be sent to the front side returns to the vicinity of the input port and accumulates, and a sufficient storage capacity cannot be obtained. In addition, the load on the drive device that drives the rotary drum may increase due to the biting of the object to be processed. Therefore, there is a risk of equipment damage or failure due to overload.

The present invention has been devised in view of the above problems, and an object of the present invention is to provide a storage / discharge device capable of efficiently and smoothly compressing an object to be processed to increase the storage capacity. And.

The disclosed storage and discharge device is a rotatable discharge port that is rotatably formed around a rotation center axis that extends substantially horizontally, has a loading portion with an opening at one end, and discharges an object to be processed at the other end. A storage portion having a feed vane spirally installed on the inner peripheral surface from one end side toward the other end side, and a storage portion having a discharge portion having a discharge portion, and the object to be processed are charged. It is provided with a charging port, and includes a charging side support portion that rotatably seals and supports the storage portion in the charging portion, and a baffle plate portion that protrudes from the periphery of the charging port toward the other end side.
The baffle plate portion is the cover in the reservoir portion of the communication port communicating with the reservoir portion and supplying the object to be processed from the input port and the left and right sides sandwiching the vertical surface passing through the rotation center axis. In the rotation direction in which the processed object is sent from the one end side to the other end side, the object to be processed is placed on the side surface of the baffle plate portion on the side where the object to be processed is scraped up by the rotation of the storage portion, and the inside of the storage portion facing the side surface. After the distance from the peripheral surface gradually narrows in the direction of rotation, a protrusion is formed so as to gradually widen.

According to the disclosed storage / discharge device, the object to be processed can be efficiently and smoothly compressed to increase the storage capacity.

The examples and modifications shown below are merely examples, and there is no intention to exclude the application of various modifications and techniques that are not specified. Each of the following configurations can be variously modified and implemented without departing from their purpose. Further, each of the following configurations can be selected as necessary except for the configuration essential to the present invention, or can be combined with a known configuration.

[1. Constitution]
FIG. 1 is a perspective view for explaining the configuration of the storage / discharge device 10 according to the embodiment. The storage / discharge device 10 includes a storage unit 1 (rotary drum) which is a hollow cylindrical member for temporarily storing the object to be processed G (garbage). The storage unit 1 is rotatably provided on the gantry 14. The gantry 14 is, for example, a frame constructed by combining steel materials and pipes, and is supported above the ground by a plurality of support legs. A support roller 15 that rotatably supports the storage unit 1 around its cylinder axis C (rotation center axis) is sandwiched between the storage unit 1 and the gantry 14.

The storage portion 1 shown in FIG. 1 is formed in a rotatable cylindrical shape around the cylinder shaft C. At one end of the storage unit 1 in the axial direction (direction along the cylinder axis C), a charging unit 2 having an opening on the inlet side of the object to be processed G is provided. The charging portion 2 is configured in a substantially cylindrical shape having a diameter equal to or less than the maximum diameter of the storage portion 1 with the cylinder shaft C as the center. The charging section 2 is closed by the loading side support section 5, which will be described later. The charging portion 2 may have a tapered portion that expands toward the opening with the cylinder shaft C as the center.
On the other hand, at the other end of the storage unit 1 in the axial direction, a discharge unit 3 having a discharge port 8 on the outlet side of the object to be processed G is provided. The discharge portion 3 is configured in a substantially cylindrical shape having a diameter equal to or less than the maximum diameter of the storage portion 1 with the cylinder shaft C as the center. The discharge unit 3 is closed by the discharge palate 11 described later. The discharge portion 3 may have a tapered portion that expands toward the discharge port 8 with the cylinder shaft C as the center.
In the following description, in the direction of the cylinder axis C of the storage unit 1, the side where the object to be processed G is discharged is simply referred to as the discharge side, and the side where the object to be processed G is charged is simply referred to as the input side.

Inside the storage unit 1, a feed blade 4 erected inward from the inner peripheral surface 9 thereof is provided. The feed blade 4 is spirally installed on the inner peripheral surface 9 of the storage unit 1 from one end in the axial direction to the other end of the storage unit 1. By rotating the storage unit 1 around the cylinder axis C, the apparent position of the feed vane 4 with respect to the inner peripheral surface 9 moves in the direction along the cylinder axis C. As a result, the object to be processed G stored inside the storage unit 1 is pressed by the feed vane 4 along the cylinder shaft C, from one end side (input side) to the other end side (discharge side) of the storage unit 1. Be transported.

The storage unit 1 is rotationally driven by a drive device such as a motor or actuator (not shown). The operating state of the drive device may be controlled manually or automatically by an electronic control device. Further, when the storage unit 1 is rotationally driven, a gear or a pulley may be attached to the outer periphery of the storage unit 1 to facilitate driving, or a transmission or various power transmission devices (gears) between the drive device and the storage unit 1 may be attached. , Chain, timing belt, etc.) may be used.

The storage unit 1 of the embodiment is configured to rotate counterclockwise when viewed from the discharge side, and is configured to be rotatable clockwise as needed. In the example shown in FIG. 1, the direction in which the spiral feed vane 4 extends in the transport direction while rotating around the cylinder axis C is set to the left hand direction. On the other hand, the rotation direction of the storage unit 1 with respect to the transport direction of the object G to be processed is set to be right-handed (reverse rotation direction of left-handed). The extending direction of the cylinder shaft C may be horizontal, may be inclined from the input side to the discharge side with a downward slope, or may be inclined with an upward slope. Further, a thrust bearing portion 32 may be installed on the discharge side of the gantry 14. The thrust bearing portion 32 supports the storage portion 1 in the cylinder axis C direction via the thrust support portion 33 arranged on the outer periphery of the discharge portion 3, and the object to be processed G is pressed and stored. A load acting in the extending direction of the cylinder shaft C may be borne.

The charging side support unit 5 has a function of supporting the storage unit 1 in a rotatably sealed state in the charging unit 2. The charging side support portion 5 is, for example, a plate-shaped member having a diameter larger than the outer diameter of one end of the storage portion 1, and the storage portion 1 is provided via a sliding member such as a bearing having a diameter corresponding to the charging portion 2 (not shown). Supports rotatably. In other words, the storage portion 1 is rotatably supported around the cylinder shaft C in a posture in which one end surface in the cylinder shaft C direction is closed by the charging side support portion 5. The charging side support portion 5 is fixed to the gantry 14, and the charging side support portion 5 does not rotate when the storage portion 1 rotates.

As shown in FIG. 2, the charging side support portion 5 is provided with a charging port 6 which is an opening for charging the object to be processed G into the storage unit 1. The loading port 6 is provided with a loading port door 7 that closes the loading port 6 so as to be openable and closable. Alternatively, a charging chute (not shown) may be connected to the charging port 6, and in this case, the object G to be processed is supplied from the charging port door 7 installed in another space partitioned by a wall or the like using the charging chute. May be done. When the insertion port door 7 is opened and manually inserted, the insertion port 6 is closed by the insertion port door 7 and locked with a mechanical key, an electronic key, or the like, except when the insertion port 6 is inserted. Alternatively, the object to be processed G may be charged into the charging port 6 by a mechanical charging device.

As shown by a fine solid line in FIG. 3B, the direction of the opening is changed inside the inlet door 7 in conjunction with the opening and closing of the inlet door 7, and the object to be processed G is temporarily held. The bucket 13 formed in the shape of a door can be fixed. When the material G to be processed is loaded into the bucket 13 having the opening facing the outside of the charging port 6 with the loading port door 7 open, the opening of the bucket 13 is inside the storage unit 1 when the loading port door 7 is closed. It is designed to flow down to the inside of the storage unit 1. Further, instead of the bucket 13, or below the bucket 13, a chute that inclines downward toward the discharge side may be installed. By providing the chute, the object to be processed G is charged into the storage unit 1 without remaining in the vicinity of the charging port 6.

The discharge port lid 11 is driven to open and close by the opening / closing device 12, and closes the discharge port 8 so as to be openable / closable. When the discharge port 8 is in the closed state, the discharge port lid 11 closes the discharge port 8 in a rotatably sealed state.

A baffle plate portion 20 formed in a shape protruding toward the other end side of the storage portion 1 is attached around the charging port 6 of the charging side support portion 5 which is one end side inside the storage portion 1. The baffle plate portion 20 is provided with at least a communication port 21 and a protruding portion 22. The baffle plate portion 20 of the embodiment is formed in a shape that is asymmetrical (non-mirror plane symmetric) with respect to the vertical plane passing through the cylinder axis C. In addition to these, the baffle plate portion 20 exemplified in FIGS. 3A to 3C is provided with a tip surface 23, an upper inclined surface 24, a lower inclined surface 25, an upper side surface 26, and a lower side surface 27.

The communication port 21 is an opening that serves as a passage for introducing the object to be processed G charged from the charging port 6 into the storage unit 1, and is formed so as to communicate with the storage unit 1. As shown in FIGS. 3A to 3C, the communication port 21 is arranged at the lower portion (lower surface) of the baffle plate portion 20. As shown by a fine solid line in FIG. 3B, when the bucket 13, the chute, or the like is provided inside the insertion port door 7, a communication port 21 having a size that does not interfere with them is formed.

The protrusion 22 has one end of the object G in the storage portion 1 on both the left and right sides of the baffle plate portion 20 sandwiching the vertical surface V [shown by a broken line in FIG. 3A] passing through the cylinder shaft C. It is provided on the side surface of the side [right side in FIG. 3A] on which the object to be processed G is scraped up in the rotation direction of the storage unit 1 transported from the side to the other end side. The protrusion 22 is projected so that the distance between the storage portion 1 and the inner peripheral surface 9 is gradually narrowed in the rotational direction and then gradually widened. The protrusion 22 shown in FIG. 3A is provided at the lower part of the side surface of the baffle plate portion 20. The protruding portion 22 is formed in a substantially triangular columnar shape extending from the plate surface of the input side support portion 5 toward the discharge side, and includes a protruding upper surface portion 28, a protruding lower surface portion 29, and a protruding tip surface 30. The protruding upper surface portion 28 and the protruding lower surface portion 29 form a portion corresponding to the side surface of the substantially triangular prism, and the protruding tip surface 30 forms a portion corresponding to the top surface of the substantially triangular prism.

The protruding upper surface portion 28 is a planar portion arranged above the protruding portion 22 and having an upward normal line, and the protruding lower surface portion 29 is a planar portion arranged below the protruding portion 22 and having a downward normal line. It is a shaped part. The distance (gap dimension) between the protruding portion 22 and the inner peripheral surface 9 of the storage portion 1 in the cross section perpendicular to the cylinder axis C is the minimum at the boundary between the protruding upper surface portion 28 and the protruding lower surface portion 29. In the example shown in FIG. 3A, the gap size is the smallest at the end on the discharge side among the ridgelines of the protruding upper surface portion 28 and the protruding lower surface portion 29. The protruding tip surface 30 is a portion of the protruding portion 22 that forms an end surface on the discharge side, and is connected in a plane between the lower inclined surface 25 and the protruding upper surface portion 28, which will be described later.

The tip surface 23 (tip) is a portion of the baffle plate portion 20 that forms the end face on the discharge side. Further, the upper inclined surface 24 is a planar portion arranged on the upper part of the baffle plate portion 20 and having an upward normal line, and is formed so as to be inclined upward from the tip surface 23 toward the insertion side. One upper inclined surface 24 is provided on the right side and one on the left side in FIG. 3A. Further, the lower inclined surface 25 is a planar portion arranged in the lower part of the baffle plate portion 20 and having a downward normal line, and is formed so as to incline downward from the tip surface 23 toward the insertion side. The lower end of the lower inclined surface 25 may be arranged so as to be lower than the lower end of the slot 6. By forming the lower inclined surface 25 in this way, it is possible to increase the effect of suppressing the return of the charged object G to the charging side.

The tip surface 23 is formed so as to project to a position where the lower inclined surface 25 intersects the feed vane 4 at least when the baffle plate portion 20 is viewed from the radial outer side to the radial inner side of the storage portion 1. In other words, the protruding length of the baffle plate portion 20 is such that the distance between the portion of the feed blade 4 closest to the loading portion 2 and the loading portion 2 is shorter than the distance from the loading portion 2 to the tip surface 23. Set.

The upper side surface 26 is a planar portion arranged on the side of the tip surface 23, and is provided so as to connect the tip surface 23 and the upper inclined surface 24 in a planar manner. The upper side surface 26 is provided on the right side and the left side in FIG. 3A with reference to the tip surface 23. Further, the lower side surface 27 is a planar portion arranged on the side of the lower inclined surface 25, and is provided so as to connect the lower inclined surface 25 and the upper side surface 26 in a planar manner. The lower side surface 27 is provided only on the left side in FIG. 3A with respect to the lower inclined surface 25. The above-mentioned protrusion 22 is projected on the right side of the lower inclined surface 25. The lower side surface 27 may be provided on the right side in FIG. 3A with reference to the lower inclined surface 25, and the protruding portion 22 may be provided on the lower side surface 27.

The object to be processed G charged from the charging port 6 is supplied to the inside of the storage unit 1 through the communication port 21 of the baffle plate portion 20. The object G to be processed is scraped up by the rotation of the storage unit 1, then falls, and is scraped up again. While repeating such scraping and dropping, the feed blade 4 feeds and stores the feed to the discharge side. The operating state of the storage unit 1 may be controlled manually or may be automatically controlled by an electronic control device. In the latter case, control may be performed based on the detection signal of the object to be processed detection sensor, or control may be performed based on the open / closed state of the input port 6. Further, the rotation drive time of the storage unit 1 may be controlled by a timer. The stored object G to be processed is discharged from the discharge port 8 to the outside of the storage unit 1 by rotating the storage unit 1 with the discharge palate 11 open, and is delivered by a discharge chute, a discharge conveyor, or the like (not shown). It is collected by a collection vehicle or the like.

Inside the baffle plate portion 20, a shielding surface 31 that shields between the upper inclined surface 24 and the lower inclined surface 25 on the front end surface 23 side of the communication port 21 may be arranged. By arranging the shielding surface 31, the strength of the baffle plate portion 20 is increased and the space inside the baffle plate is limited, and the object to be processed G enters the tip surface 23 side of the communication port 21 and interferes with it. It does not stay inside the plate portion 20, and is smoothly supplied into the storage portion 1 from the communication port 21.

[2. Action and effect]
4 (A) to 4 (D) are views for explaining the movement of the object to be processed G in the storage portion 1, and is a front view of the baffle plate portion 20 (viewed from the discharge side to the input side). It is a front view at the time. The rotation direction of the storage unit 1 is counterclockwise in FIGS. 4A to 4D.

The object to be processed G thrown into the storage unit 1 is scraped up by the feed blade 4, pressed against the inner peripheral surface 9 of the storage unit 1, compressed, and moves counterclockwise. The protrusion 22 functions as a stopper for preventing the scraped object G to return to the vicinity of the communication port 21. As a result, as shown in FIG. 4B, a space S for scraping up and feeding the object to be processed G is secured around the communication port 21, and the newly input object G to be input is smoothly fed.

The protrusion 22 has a shape in which the distance from the inner peripheral surface 9 of the storage portion 1 gradually narrows in the rotational direction and then gradually widens. As a result, the object to be processed G is gradually compressed between the projecting portion 22 and the inner peripheral surface 9, so that an extra load is not applied to the drive device of the storage portion 1. Further, as shown in FIG. 4C, an appropriate space S is secured above the protruding portion 22. As a result, the object G to be processed that has passed through the narrowest portion moves to the upper side of the protrusion 22 without resistance.

In this way, an extra load is not applied to the drive device of the storage unit 1 due to the biting of the object to be processed G, and damage or failure of the device due to the overload is prevented. Further, by forming the protruding portion 22 at the lower part of the side surface of the baffle plate portion 20, the object to be processed G can be compressed early. As a result, it is possible to easily feed the object to be processed G and reduce an extra load on the apparatus at the time of scraping. After that, the object to be processed G scraped up by the feed blade 4 moves to the upper part of the baffle plate portion 20 as shown in FIG. 4D, and falls on the upper inclined surface 24 due to its own weight. The object to be processed G is transferred to the discharge side deeper than the tip surface 23 of the baffle plate portion 20.

The storage / discharge device 10 according to the embodiment has the following effects.
(1) Even if the object to be processed G is nearly full, the object to be processed G can be further sent to the discharge side. Therefore, for example, the compression rate can be improved to about twice and the storage amount can be increased as compared with the conventional storage / discharge device provided with the baffle plate portion 20 in which the protrusion 22 is not formed. Therefore, according to the disclosed storage / discharge device 10, the object to be processed G can be efficiently and smoothly compressed to increase the storage capacity. Further, since the compression rate increases, the storage unit 1 can be miniaturized. Further, since a sufficient storage capacity can be obtained even if the size is reduced, the manufacturing and installation costs can be reduced, and the storage space can be effectively utilized.

(2) In the above embodiment, the baffle plate portion 20 is provided with the upper inclined surface 24 and the lower inclined surface 25. The upper inclined surface 24 allows the object to be processed G that has fallen from the inner peripheral surface 9 to be sent to the discharge side. Further, the lower inclined surface 25 secures a space S for feeding the object to be processed G between the feed blades 4 in which the object to be processed G is easily clogged, and the inner circumference of the object to be processed G is squeezed by rotation. A pushing force can be applied to the surface 9 side. As a result, even if the storage unit 1 is nearly full, the object to be processed G can be efficiently sent to the discharge side.

(3) In the above embodiment, the tip surface 23 of the baffle plate portion 20 is formed so as to project to a position where the lower inclined surface 25 intersects the feed vane 4 when viewed from the radial direction of the storage portion 1. As a result, the object to be processed G flowing down on the upper inclined surface 24 can be sent to the inner part of the discharge side, and the storage capacity of the object to be processed G can be increased. Further, as shown in FIG. 5, the space S secured below the lower inclined surface 25 can be increased.

[3. Modification example]
6 (A) to 6 (E) are diagrams illustrating the configuration of the storage / discharge device 10 according to the modified example.
In the above embodiment, the projecting portion 22 including the projecting upper surface portion 28 and the projecting lower surface portion 29 has been exemplified, but the specific shape of the projecting portion 22 is not limited to this. For example, the protruding portion 22 may be formed so that the outer periphery is curved when viewed from the discharge side, that is, the outer periphery does not include the corner portion. The protruding portion 22'shown in FIG. 6A is formed so as to draw a curve (for example, an arc) whose outer peripheral shape seen from the discharge side does not include a corner portion and gradually changes as the entire circumference. With such a configuration, the object to be processed G can be fed more smoothly. In addition, in order to feed the object to be processed G more smoothly, as shown in FIG. 6E, not only the protruding portion 22, but also the tip surface 23, the upper inclined surface 24, the lower inclined surface 25, the upper side surface 26, and the lower side surface 27. The entire baffle plate portion 20''' may be formed into a smooth curved surface.

In the above embodiment, the baffle plate portion 20 formed in a shape of left-right asymmetry (non-mirror plane symmetry) with respect to the vertical plane passing through the cylinder axis C is illustrated, but the hindrance plate portion 20 is left-right symmetric with respect to the plane parallel to the vertical plane passing through the cylinder axis C. It may be formed in a (mirror-symmetrical) shape. In this case, the gap dimension on the side surface side of the baffle plate portion 20 can be reduced by arranging the baffle plate portion 20 so as to be offset from the vertical plane passing through the cylinder axis C, and a part of the baffle plate portion 20 is used as the protrusion portion 22. Can be made to work.

In the above embodiment, the overall shape of the baffle plate portion 20 excluding the protrusion 22 is substantially symmetrical (mirror surface symmetry), and by adding the protrusion 22, the shape becomes left-right asymmetric (non-mirror surface symmetry). ing. Such a structure is useful, for example, when the protrusion 22 is added to the existing baffle plate portion 20 having no protrusion 22, and is also advantageous in terms of cost. On the other hand, as shown in FIG. 6B, it is also possible to form the entire shape of the baffle plate portion 20'in advance into a left-right asymmetric (non-mirror plane symmetric) shape.

Further, as shown in FIG. 6C, the protruding lower surface portion 29 of the baffle plate portion 20 ″ may be omitted, and the communication port 21 may be extended to the lower portion of the protruding portion 22. In this way, the communication port 21 may be expanded. By doing so, a large amount of the object to be processed G can be supplied to the side (feeding side) for scraping up the object to be processed G, and the object to be processed G can be quickly scraped up and sent out.

In the above embodiment, the storage unit 1 having one feed vane 4 is illustrated, but the number of feed vanes 4 can be a plurality. For example, as shown in FIG. 6D, a second feed blade 4'which has a phase different from that of the feed blade 4 may be provided. By providing the plurality of feed blades 4, 4'in this way, the object to be processed G can be fed more efficiently. The second feed blade 4'may be shorter than the first feed blade 4 and may be arranged between the baffle plate portion 20 and the tip surface 23. For example, if it is arranged between the charging side of the storage portion 1 and the tip surface 23 of the baffle plate portion 20 as shown in FIG. 6D, it is possible to prevent the object to be processed G from being over-compressed on the discharging side. It should be noted that the larger the number of feed blades 4 and 4', the higher the ability to feed the object to be processed G. Sufficient feeding capacity can be maintained even with a number.
