Article 30, Paragraph 2 of the Patent Act applies Exhibition name: FOOMA JAPAN 2019 Date: July 9-12, 2019

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport elevator for lifting grains and the like.

A conveying device used in a conveying elevator used in an automatic grain weighing device or the like consists of a driving pulley and a driven pulley which are vertically spaced apart from each other, and an annular bucket belt which is suspended between the two pulleys. It is common to install a bucket conveyor made up of slender transport channels.

Bucket belts of bucket conveyors not only become dirty when conveyed objects adhere to them, but also deteriorate, requiring cleaning or replacement. However, the hoisting path with the bucket belt installed is surrounded on all sides by the fuselage in order to prevent the objects being transported from scattering and to ensure the safety of workers, and narrow openings are formed at the top and bottom ends. It was difficult just to clean it because it was just there. Moreover, when replacing the bucket belt, the ring-shaped bucket belt must be separated and removed, and a new belt-shaped, long and heavy belt can be passed through narrow openings at the top and bottom and passed around both pulleys. It was necessary to join them in a ring shape by work, and the burden required for the replacement work was heavy and it took a lot of time and effort.

Therefore, conventionally, a conveyor belt with a large number of buckets mounted thereon is suspended between an upper pulley and a lower pulley to constitute a self-supporting conveying unit. A formed grain transport elevator is disclosed in US Pat.
In this elevator, since the self-supporting conveying unit is largely exposed by removing the cover, it is possible to easily and reliably remove bran, etc. adhering to the inside of the conveying path, and maintenance and inspection of the inside is facilitated.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, it cannot be overemphasized that this invention is not limited to embodiment. In this embodiment, the transport elevator will be described as a grain transport device that uses grain as the object to be transported.

As shown in FIGS. 1, 2 and 7, the grain conveying/elevating machine 1 lifts grain such as rice, puts it into a bag, and automatically weighs it. and a cover 7 that covers the transport device 3 .
The lower part of the cover 7 is provided with an inlet 5 for charging grain into the grain conveying elevator 1, and the upper part of the body 2 is provided with a discharge port 4 for discharging the grain lifted by the conveying device 3. be done. A weighing scale for placing paper bags is installed below the discharge port 4 .

The cover 7 is provided on the body 2 so as to be openable and closable. The cover 7 is pivotally supported with respect to the body 2, covers the conveying device 3 from the outside when the cover 7 is closed, and exposes the conveying device 3 to the outside when the cover 7 is opened.
As shown in FIGS. 3 to 5, the body 2 is formed with a partition wall 8 that supports the carrier device 3 to be attached. The partition wall 8 separates the inside of the body 2 from the outside of the body 2 on the conveying device 3 side, is positioned on one side of the conveying device 3, and is formed along the vertically elongated conveying device 3 .

As shown in FIG. 7, the cover 7 is rotatably supported via a hinge provided on a shaft parallel to the conveying direction of the conveying device 3 on the side of the body 2 (an axis extending in the vertical direction). . The cover 7 is attached to the body 2 in a one-sided opening opening outward.
The cover 7 is a single piece, and is configured to cover the conveying device 3 when the cover 7 is closed and positioned to face the partition wall 8 of the body 2 so as not to be exposed to the outside. In this state, the conveying device 3 is accommodated in the space formed by the body 2 and the cover 7. As shown in FIG.

As shown in FIGS. 3 to 6, the conveying device 3 includes a driving pulley 9 provided in the lower portion, a driven pulley 10 provided in the upper portion, and suspended between the driving pulley 9 and the driven pulley 10 to circulate in the vertical direction. It has an annular bucket belt 11 that
The rotating shaft 9a of the driving pulley 9 and the rotating shaft 10a of the driven pulley 10 are substantially parallel to each other, arranged substantially perpendicularly from the partition wall 8, and supported.
A large number of buckets 12 are attached to the outer peripheral surface of the bucket belt 11 at regular intervals in the circumferential direction.

As shown in FIGS. 3 and 4, the driven pulley 10 has one end of its rotating shaft 10a supported above the partition wall 8. As shown in FIGS.
A rotating shaft 10 a of the driven pulley 10 is supported by the partition wall 8 in a cantilever manner. The rotating shaft 10a is inclined so as to gradually rise from the end of the body 2 on the side of the partition wall 8, which is the fixed end, toward the end on the side of the cover 7, which is the free end. By providing such an inclination angle, even if the driven pulley 10 is cantilevered, the bucket belt 11 is less likely to come off. The angle of inclination of the rotary shaft 10a is as slight as about 1 degree, and there is no problem in circulating the bucket belt 11 between the driving pulley 9 and the driven pulley 10, and the bucket belt 11 can be attached and detached while it is annular. It does not interfere with work.

As shown in FIGS. 3 and 5, the drive pulley 9 has one end of its rotary shaft 9a passing through the partition wall 8 and connected to the output shaft of the motor 13. As shown in FIGS. The motor 13 is installed inside the body 2 and supported by the partition wall 8 .
Moreover, the partition wall 8 is provided with a bracket 22 projecting toward the cover 7 side from the inner position surrounded by the bucket belt 11 at its lower portion. The tip of the bracket 22 is bent parallel to the end face of the drive pulley 9, and the other end of the rotating shaft 9a is supported by a bearing 21 provided at this bent portion. Both ends of the rotating shaft 9a of the drive pulley 9 are supported by the partition wall 8, so that the structure of the drive pulley 9 is stable.
Since all the components of the bracket 22 are arranged inside the area surrounded by the annularly suspended bucket belt 11, attachment and detachment of the bucket belt 11 is not hindered.

Thus, the rotating shafts 9 a and 10 a of the drive pulley 9 and the driven pulley 10 are supported by the body 2 and not supported by the cover 7 . When the cover 7 is closed, the cover 7 is positioned to face and cover the side surfaces of the transfer device 3 substantially perpendicular to the rotating shafts 9a and 10a.

As shown in FIG. 4, the rotary shaft 10a of the driven pulley 10 is rotatably attached to a support base 14 overlapping the upper back surface of the partition wall 8 via a bearing 21. As shown in FIG.
The support base 14 is movable with respect to the partition wall 8 along the vertical direction, which is the conveying direction of the conveying device 3, and a position adjusting device capable of adjusting the position of the driven pulley 10 as follows. Configure.
Both side ends of the support base 14 are slidably engaged with a pair of guide rails 16 fixed to the rear surface of the partition wall 8 along the vertical direction. As shown in FIGS. 4 and 6, the support base 14 is connected to an operating portion 19 of a position adjusting device installed between the drive pulley 9 and the driven pulley 10 inside the bucket belt 11. there is The operating portion 19 is composed of an adjust bolt 17 and a tension spring 18 connected to the upper end of the adjust bolt 17, and the support base 14 is urged upward by the tension spring 18. As shown in FIG.

By rotating the adjusting bolt 17 of the operating portion 19, the tension spring 18 is moved up and down to adjust the height of the support base 14, thereby adjusting the vertical position of the driven pulley 10 attached to the support base 14. can do.
An eave-like dust cover 20 protrudes from the partition wall 8 above the operating portion 19 of the position adjusting device. Therefore, the grains conveyed by the bucket belt 11 and the powder particles scattered in the conveying space are prevented from falling and adhering to the operation portion 19 of the position adjusting device, so that the adjustment bolt 17 can be operated without hindrance. become.

When the motor 13 is driven, the drive pulley 9 rotates, the bucket belt 11 suspended between the drive pulley 9 and the driven pulley 10 circulates and rotates in the vertical direction, and the driven pulley 10 rotates in the same direction as the drive pulley 9 .
As the bucket belt 11 circulates, the grain stored in the bucket 12 in the lower part of the conveying space is conveyed upward and discharged from the bucket 12, and the empty bucket 12 descends to the lower part of the conveying space.

While the grain is being lifted, as shown in FIG. 2, the cover 7 is closed to close the transfer space.
When the cover 7 is opened as shown in FIG. 7, the drive pulley 9, the driven pulley 10, and the bucket belt 11 covered by the cover 7 are largely exposed to the outside. That is, the cover-side side surface of the conveying device 3 is entirely exposed.
Therefore, it is possible to easily clean the drive pulley 9, the driven pulley 10, the bucket belt 11, and the bran or the like adhering to the inside of the transfer space.

In addition, since the end portions of the rotating shaft 9a of the drive pulley 9 and the rotating shaft 10a of the driven pulley 10 are exposed to the outside without being supported by the cover 7, the bucket belt 11 is driven while being looped. It can be attached to and detached from the pulley 9 and the driven pulley 10 .
For example, when replacing the bucket belt 11, the adjustment bolt 17 of the operation portion 19 of the position adjustment device is operated to lower the support base 14 and the driven pulley 10 supported thereon. As a result, the driving pulley 9 and the driven pulley 10 approach each other and the bucket belt 11 is loosened. Therefore, as shown in FIG. 8, the old bucket belt 11 can be easily removed in its annular state. In addition, in FIG. 8, the operation part of the position adjusting device is omitted.

Then, after winding the new bucket belt 11 in a loop between the drive pulley 9 and the lowered driven pulley 10, the adjustment bolt 17 of the operation portion 19 is operated, and the support base 14 and the driven pulley 10 are to raise
As a result, the distance between the driving pulley 9 and the driven pulley 10 is increased, and the bucket belt 11 is tense, so that the bucket belt 11 circulates stably without slipping.
In this manner, when the cover 7 is opened, the operating portion 19 of the position adjusting device for the driving pulley 9 is also exposed to the outside, so that the operating portion 19 can be easily accessed.
Moreover, not only can the bucket belt 11 be attached and detached, but also the tension of the bucket belt 11 can be easily adjusted.

If the bucket belt 11 circulates while the cover 7 is opened to expose the conveying device 3 to a large extent, the grains being lifted by the bucket belt 11 may scatter or the worker may be injured by touching the bucket belt 11. Since there is a fear, a safety device may be installed that detects that the cover 7 is open, regulates the driving of the motor 13, and stops the circulation of the bucket belt 11 when the cover 7 is open. good.

[Other Modifications]
The present invention is not limited to the above embodiments. Examples include:

In the present embodiment, the elevator lifts grain, but the invention is not limited to this, and any object to be transported may be transported by a bucket belt.

In this embodiment, a single one-sided cover is pivotally supported by the body, and when the cover is closed, the entire side surface of the conveying device is covered. Then, it may be covered with two double-door covers.
Also, the cover may be vertically divided into two or more by a horizontal dividing line.

In the present embodiment, the cover is pivotally supported on the body so as to be openable and closable via a hinge provided on a shaft parallel to the conveying direction (vertical direction) of the conveying device. It may be pivotally supported so as to be openable/closable via a hinge provided on a shaft in a direction (horizontal direction) perpendicular to the transport direction of the transport device.
In addition, the cover is vertically divided into, for example, three parts along a horizontal dividing line. The lower cover is pivotally supported on the body via a hinge provided on a shaft parallel to the transport direction (vertical direction) of the transport device, and a hinge provided on a shaft perpendicular to the transport direction (horizontal direction) of the transport device. You can do so.

In this embodiment, the position of the driven pulley positioned at the top is vertically adjustable. This is because a gap of 5 to 10 mm is required between the bottom of the conveying device and the lowest bucket to prevent crushing of the grain when scooping the grain with the bucket at the lower end of the bucket belt. If the position of the driving pulley located in the position of the drive pulley is adjusted, it will be necessary to adjust the position of the driven pulley located in the upper part, which does not need to be adjusted. I am trying to fix the drive pulley.
Therefore, if the object to be conveyed is not easily crushed, if there is no particular problem even if it is crushed, or if there is no problem even if fine adjustment work is not expected at the lower part, a position adjusting device is provided for the lower drive pulley. can be
In addition, position adjusting devices may be provided on both the upper driven pulley and the lower driving pulley.
Furthermore, the position adjusting mechanism is not limited to the one described in the above embodiment.

In this embodiment, since it is preferable to install the heavy motor in the lower part of the body, the lower part is used as the driving pulley and the upper part is used as the driven pulley, but it is also possible to use the lower part as the driven pulley and the upper part as the driving pulley.
Also, the motor installed in the lower part of the body may be supported by the bottom surface of the body without being supported by the partition wall.

In this embodiment, a bracket is provided to support the rotating shaft of the lower drive pulley on both sides, but the bracket may be applied to the upper driven pulley.

In this embodiment, the rotation axis of the driven pulley provided at the top is inclined so as to gradually rise from the end on the body side toward the end on the cover side. can also be similarly tilted.

It is good also as an example by applying each technical matter in any embodiment to other embodiments.
