Description

The present invention relates to a chute device for a conveyor.

For example, when using a conveyor to transport objects such as chopper scraps, normally multiple conveyors of a predetermined length are installed, and the objects are transferred from the upstream conveyor to the downstream conveyor and transported to a predetermined position. things are being done.

In the case of such a conveyor, there is a difference in height between the upstream conveyor and the downstream conveyor, and when the conveyed object falls onto the downstream conveyor, it bounces and scatters to the outside of the downstream conveyor, resulting in unnecessary cleaning. There is a possibility that work will be required. In addition, the shock caused by falling objects may accelerate wear on the downstream conveyor, and the objects may not be placed in the center of the downstream conveyor, but may be loaded unevenly, causing meandering of the downstream conveyor. There was also a fear.

Therefore, conventionally, a structure has been proposed in which a chute device is installed in the transfer section to control the falling angle, falling position, falling speed, etc. of the transported object. For example, Patent Document 1 discloses a chute device in which a chute stand provided with an inclined surface for guiding conveyed objects is configured to be swingable. Further, Patent Document 2 discloses a chute device in which a link chain for controlling the falling position of conveyed objects is disposed facing the downstream side of an upstream conveyor.

However, in the chute device disclosed in Patent Document 1, the falling angle and falling speed of the conveyed object become uneven depending on the weight and size of the conveyed object, so it is difficult to control the falling position with respect to the downstream conveyor. . Furthermore, the falling speed of the conveyed object becomes relatively high, and there is a risk that the conveyed object may be scattered due to rebound when falling, or the downstream conveyor may be damaged due to the impact when falling.

In addition, in the chute device disclosed in Patent Document 2, the falling angle and falling position can be controlled to a certain extent by the conveyed object coming into contact with the link chain, but the fulcrum position is fixed, and various sizes are available. It is difficult to perform the same function for conveyed objects. In addition, the falling speed of the conveyed object becomes relatively high, and there is a risk that the conveyed object may be scattered due to rebound when falling, or the downstream conveyor may be damaged due to the impact when falling.

The present invention has been made in view of the above problems, and an object thereof is to provide a conveyor chute device that allows easier control of the falling angle, falling position, falling speed, etc. of conveyed objects.

In order to solve the above-mentioned problems and achieve the objects, a conveyor chute device according to the present invention is installed at a transfer section between an upstream conveyor and a downstream conveyor, and transports the conveyed objects that have fallen from the upstream conveyor to the downstream conveyor. a chute stand provided with an inclined surface guiding toward a side conveyor; and a first chute stand disposed opposite to the downstream end of the chute stand, extending in the up-down direction, and facing the up-down direction and the end. and a guide plate configured to be swingable around a rotation center extending in a second direction intersecting the direction.

Further, the lower end portion of the guide plate is provided with a bent portion bent at an angle of 90° to 135° with respect to the base portion of the guide plate.

Further, the guide plate is provided so that its position in the first direction can be adjusted with respect to the chute stand.

According to the present invention, it is possible to provide a conveyor chute device in which the falling angle, falling position, falling speed, etc. of conveyed objects can be more easily controlled using the chute stand and the guide plate.

[Embodiment]
FIG. 1 is a schematic front view of a chute device 1 of a conveyor according to an embodiment, FIG. 2 is a schematic side view of the chute device 1, and FIG. It is an explanatory diagram explaining a route.

As shown in FIGS. 1 to 3, the chute device 1 is installed at a transfer section between an upstream conveyor 11 and a downstream conveyor 12, and includes, for example, a chute stand 3 and a guide plate 6. The chute device 1 can guide the conveyed object 2 that has fallen from the upstream conveyor 11 toward the downstream conveyor 12 using the chute stand 3 and the guide plate 6 .

Note that in the following description, three mutually orthogonal directions are defined for convenience. The Z direction is along the height direction (vertical direction) of the guide plate 6, the X direction is along the thickness direction of the guide plate 6, and the Y direction is along the width direction of the guide plate 6. The X direction is an example of a first direction that faces the downstream end 5b of the chute table 3, and the Y direction is an example of a second direction that intersects the vertical direction and the first direction.

Note that the X direction is parallel to the width direction of the downstream conveyor 12 and substantially parallel to the longitudinal direction of the upstream conveyor 11. Further, the Y direction is parallel to the longitudinal direction of the downstream conveyor 12 and parallel to the width direction of the upstream conveyor 11.

As shown in FIGS. 1 and 3, the chute stand 3 includes, for example, an upper chute 4 and a lower chute 5. The lower chute 5 is located downstream of the upper chute 4 in the transport path of the object 2 . That is, in the conveyance path, the upper chute 4 is located between the upstream conveyor 11 and the lower chute 5, and the lower chute 5 is located between the upper chute 4 and the downstream conveyor 12.

The upper chute 4 and the lower chute 5 are provided with inclined surfaces 4a and 5a, respectively. The inclined surfaces 4a and 5a are inclined downward, that is, closer to the downstream conveyor 12 as they move away from the upstream conveyor 11 in the opposite direction of the X direction. The upper chute 4 and the lower chute 5 can transport the object 2 along the inclined surfaces 4a and 5a.

Here, in this embodiment, the inclination angle of the inclined surface 5a with respect to the X direction (horizontal surface) is set smaller than the inclination angle of the inclined surface 4a with respect to the X direction (horizontal surface). This reduces the conveyance speed of the conveyed object 2 on the inclined surface 5a, and makes it easier for the conveyed object 2 to collide with a guide plate 6, which will be described later.

The guide plate 6 is located close to (adjacent to) the lower chute 5 in a direction opposite to the X direction. In other words, the guide plate 6 is arranged to face the downstream end 5b of the lower chute 5. The guide plate 6 is positioned so that at least a portion thereof overlaps with an extension of the inclined surface 5a of the lower chute 5. The guide plate 6 has, for example, a base portion 6c and a bent portion 6d.

FIG. 4 is an enlarged view of section IV in FIG. 3. As shown in FIG. 4, the bent portion 6d is provided at the lower end portion 6b of the guide plate 6. As shown in FIG. The bent portion 6d is bent from the base portion 6c of the guide plate 6 toward the lower chute 5, that is, in the X direction. In this embodiment, the inclination angle θ of the bent portion 6d with respect to the base portion 6c is set to an angle of 90° to 135°.

In addition, in this embodiment, the case where the bending part 6d is an inclined part which inclined so that it approaches the lower chute 5 as it goes downward from the base part 6c was illustrated, but it is not limited to this example. It may be a right angle part at a right angle (90°) to 6c. The length of the bent portion 6d is desirably set to approximately 1 to 3 times the length (diameter) of the conveyed object 2, for example.

FIG. 5 is an enlarged view of the upper end 6a of the guide plate 6 in FIG. As shown in FIG. 5, a U-shaped bolt 9 is attached to the upper end 6a of the guide plate 6. The U-shaped bolt 9 is fixed to the guide plate 6 with a nut 15 with the shaft 7 sandwiched therebetween. A slight gap is provided between the shaft 7 and the U-shaped bolt 9.

In this embodiment, the guide plate 6 is configured to be swingable around the rotation center Ax of the shaft 7 extending in the Y direction, using the shaft 7 and the U-shaped bolt 9 as fulcrums. As shown in FIG. 2, a plurality of U-shaped bolts 9 are provided on the upper end 6a of the guide plate 6 at intervals in the Y direction. The shaft 7 is fastened to the conveyor frame 13 by, for example, fixing bolts 8 or the like.

Further, the shaft 7 is slidably supported within an opening 13a of the conveyor frame 13 shown in FIG. 1, for example. In this embodiment, the operator loosens the above-mentioned fixing bolt 8, grabs the handle 10, and changes the position of the shaft 7 within the opening 13a, thereby moving the guide plate 6 in the X direction relative to the chute stand 3. The mounting position is adjustable. That is, the guide plate 6 is configured to be movable between a first position P1 close to the lower chute 5 and a second position P2 spaced apart from the lower chute 5.

FIG. 6 is an explanatory diagram illustrating the swinging operation of the guide plate 6. As shown in FIG. 7 and 8 are explanatory diagrams for explaining the swinging operation of the guide plate 6. FIG. 7 is a diagram showing a state after the state shown in FIG. 6, and FIG. 8 is a diagram showing a state after the state shown in FIG. It is a diagram showing a later state.

First, the conveyed object 2 slides down on the inclined surfaces 4a and 5a of the upper chute 4 and the lower chute 5, and then collides with the guide plate 6. Specifically, the conveyed object 2 collides with the vicinity of the upper end of the bent portion 6d of the guide plate 6, which is located on an extension of the inclined surface 5a. At this time, the guide plate 6 absorbs the impact of the conveyed object 2 by swinging around the rotation center Ax of the shaft 7, and as shown in FIG. It can be placed.

Then, as shown in FIG. 7, the guide plate 6 tilts (swings) around the rotation center Ax due to the weight of the transported object 2, and as shown in FIG. It slowly falls near the center position of the side conveyor 12 in the X direction. In this manner, according to the present embodiment, the articles 2 can be loaded onto the downstream conveyor 12 at the intended position using the guide plate 6.

As described above, in this embodiment, the conveyor chute device 1 is installed at the transfer section between the upstream conveyor 11 and the downstream conveyor 12, and directs the conveyed object 2 that has fallen from the upstream conveyor 11 to the downstream conveyor 12. A chute stand 3 is provided with inclined surfaces 4a and 5a for guiding the chute stand, and is disposed facing the downstream end 5b of the chute stand 3, extends in the Z direction (up and down direction), and has slopes 4a and 5a for guiding. It includes a guide plate 6 configured to be swingable around a rotation center Ax extending in a Y direction (second direction) that intersects the opposing X direction (first direction).

According to such a configuration, for example, the conveyed object 2 that has slid out from the downstream end 5b of the chute table 3 can be caused to collide with the guide plate 6, and the guide plate 6 can be swung around the rotation center Ax. By moving, the impact of the transported object 2 can be absorbed. This makes it easier to control, for example, the falling angle, falling position, falling speed, etc. of the conveyed object 2, and as a result, the conveyed object 2 is not loaded at the center position of the downstream conveyor 12 in the X direction, but is biased. This can prevent inconveniences such as meandering of the downstream conveyor 12.

Further, in this embodiment, the lower end portion 6b of the guide plate 6 is provided with a bent portion 6d bent at an angle of 90° to 135° with respect to the base portion 6c of the guide plate 6. By setting the bending part 6d at 90° or more, it becomes difficult for the transported object 2 to stay on the bending part 6d, and by setting the bending part 6d at 135° or less, it becomes easier to hold the transported object 2 on the bending part 6d. The angle θ is preferably set to 90° to 135°.

According to such a configuration, for example, the bending portion 6d makes it easier to control the falling angle, falling position, falling speed, etc. of the conveyed object 2, and the rebound of the conveyed object 2 when it falls causes the conveyed object 2 to bounce off the downstream conveyor. Inconveniences such as scattering to the outside of the conveyor 12 or damage to the downstream conveyor 12 due to impact when dropped can be further suppressed.

Moreover, in this embodiment, the guide plate 6 is provided so that its position in the X direction can be adjusted with respect to the chute table 3.

According to such a configuration, for example, the guide plate 6 makes it easier to handle a plurality of conveyed objects 2 having different weights and sizes, and furthermore, it is possible to further suppress the inconvenience caused by insufficient control of the conveyed objects 2 described above.

Although the embodiments of the present invention have been illustrated above, the above embodiments are merely examples and are not intended to limit the scope of the invention. The embodiments described above can be implemented in various other forms, and various omissions, substitutions, combinations, and changes can be made without departing from the gist of the invention. In addition, specifications such as each configuration and shape (structure, type, direction, format, size, length, width, thickness, height, number, arrangement, position, material, etc.) may be changed as appropriate. It can be implemented.
