<Regarding conventional technology> Conventional belt conveyors are known to have a belt made of rubber or the like rotatably wrapped around a belt rack, and objects to be transported are placed on the belt and conveyed, or the objects to be transported are conveyed above the belt conveyor. When conveying to distant places or high places, means such as connecting belt conveyors were used.

<Problems to be Solved by the Invention> Conventionally, when transferring objects from a low place to a high place, belt conveyors are sequentially connected toward the high place and transferred in a relay type, or conveyor belts are connected at regular intervals. Packets were attached to the floor and transported to high places by continuous rotation up and down, but for example, when transporting items from the first floor to the second floor, there was no need to relay a belt conveyor, and there was no need to use a packet conveyor. Therefore, it is an object of the present invention to provide a belt conveyor that can be used to transport objects in particularly narrow spaces without requiring human intervention.

(B) Regarding the structure of the invention The present invention has been made with the above-mentioned objectives, and will be described in detail below with reference to the drawings which are embodiments.

The first figure is a side view schematically illustrating the belt conveyor device of the present invention, which is composed of the following nine mechanisms.

That is, it consists of a belt conveyor support mechanism, a one-rotation conveyance mechanism, attached mechanisms, and other mechanisms. These Ia structures will be sequentially explained below.

■About the belt conveyor support mechanism This mechanism consists of columns and 41! that support the entire belt conveyor that rotates upward and downward. (17) and a box gutter-shaped support frame (21) that directly or indirectly supports and stores the main parts of the rotary conveyance mechanism described below. ) and support columns (17
) and is supported vertically on the rod (17). In the drawings, which are examples, the lower part of the ascending and descending conveyor, which is the storage part, faces the conveyance belt conveyor (10) at an obtuse angle, and the upper part of the ascending conveyor part (1()) is the storage part of the conveyance belt conveyor (10). Facing the delivery belt conveyor (11), it is configured gradually horizontally from an acute angle, and the space between is configured vertically, and the upper storage section of the descending conveyor section (Y) is configured horizontally with a length of approximately The support frame (21), which is vertically descended to reach the lower component part, has a box-like gutter-like support frame (21), and the entire structure is slightly C-shaped.

The upper and lower belt rotation positions and each bending rotation position are provided with gear wheels (3-1), (3-2), and (3-3), respectively.
3) (3-4) (3-5) (3-6) and drive tooth shaft (2
A rotary shaft mounting hole (20) of 3) is provided in the side plate (18).

■About the rotating conveyance mechanism This mechanism includes a motor (22), chain (2), drive gear (23), gear wheels (3-1) to (3-6), belt holding frame (5), belt (7), etc. It consists of

Each of these components will be explained in sequence.

A motor (22) as a driving source is supported by a support column or a rail (17) at the top of the device and is connected to the ascending conveyor section (
) A bell h (2) is attached to the drive shaft (24) of the drive gear (23) provided at the position where
5) are connected.

The drive toothed wheel (23) and each of the toothed wheels (3-1) to (3-6) are rotatable wheels that are rotatably supported by the support frame side plates (18) at each bending position of the support frame (21) described above. Axis (26)
It is pivoted close to the inside of both side plates (18) so as to rotate coaxially with the support column (17).

The chain (2) includes a pair of drive gear wheels (2) each pivoted on the inside of both side plates (18) of the support frame (21). r@(3-1) to (3-6), and the two chains (2) rotate at the same time.

The belt holding frame is formed into a quadrilateral shape by the front and rear horizontal frame members (6) and (8) and the left and right vertical frame members (27), and one end of the left and right vertical frame members (27) is spaced at appropriate intervals. It is detachably attached to a joint (4) which is fixedly attached to the inner surface of the chain (2).

Note that this installation is configured so that it always has an acute angle with respect to the rotating direction of the chain (2), and the angle to be made depends on the type of object to be transferred, the size of the installation location of the belt conveyor, and the height of the space. The height may be set to be most convenient for lifting and dropping objects.

The belt (7) is passed over the belt holding frame (5), and the width of the belt (7) is of course approximately equal to the width of the belt holding frame (5). Belt holding frame (5
) and extend it diagonally to the rear horizontal frame member (8) of the belt holding frame (5) at the rear with respect to the rotating direction, and then From the relevant holding frame (5)
It is stretched along the vertical frame member (27) up to the front horizontal frame member (6) and wrapped around the frame member (6).

In such a case, the belt (7) should be placed between the front and rear belt holding frames (5).
) is stretched in an L-shape with an acute angle bend. chain(
2) The belt conveyor of the present invention is constructed by continuously extending belts (7) in an L-shape as described above between the respective belt holding frames (5) provided above. In addition, when the belt conveyor is used, for example, to transport small fish for drying, it is also possible to use a fine mesh mesh to improve drainage during transport, and in this case, the L-shaped folds of the mesh can be
Before stretching each belt holding frame (5) in an L-shape, creases may be formed in advance at the bent portions.

If the belt material is made of a flexible material such as a rubber belt, a hinge-shaped rotary tool (J2') may be used at the bent portion (fold) (12) to allow the belt to bend easily.

(■About the attached mechanism) In order to assist in L-shaped bending of fine mesh, rubber belts, etc., air nozzles (1, 3-2) are installed as a bending biasing mechanism close to the starting point of the rotational rise of the lowest gear ring (3-1,). A rotary belt pusher (28) may be attached to blow air onto the belt (7), or a rotating belt pusher (28) may be attached to push the belt (7).

In addition, in the case of a fine-mesh belt, air nozzles (1, 3-1) may be provided at appropriate positions in the ascending or descending section of the belt to clean the upright part of the L-shaped belt with air, and also to clean the rising part of the ascending conveyor part ()l). An air nozzle (13) may be provided near the upper transfer object falling position to face the falling direction to help the transfer object (9) fall. Especially if a water washing nozzle (14) is attached to the vertical descending part (H-6) of the belt (7),
This is particularly effective in fine mesh belt conveyors for transporting small fish.

Next, since the chain (2) has a considerable weight, it is likely that it will sway back and forth and from side to side during the rotation of conveying the transferred object.
In order to stop this shaking, a chain (2
) can be completely prevented by attaching chain swing prevention devices (15) close to the front and rear of the chain.

The conveyor belt conveyor (11) is installed horizontally toward the lower inclined ascending section (H-1) of the ascending conveyor section (H), and the conveyance belt conveyor (11) is installed horizontally toward the downward ascending section (H-1) at the upper part of the ascending conveyor section (H).
3) and the downward horizontal rotation section (H-4) (transferred object falling section), it is installed horizontally so as to be able to receive the transferred object (9). or(
31) is a rotation regulator for the motor (22).

(c) Regarding the operation of the invention When using the belt conveyor of the present invention to transfer the object (9) from the lower part to the upper part, when the motor (22) is started, the drive gear (23) rotates and the chain (2) ) begins to rotate upward and downward 6 At this time, in the ascending part (H) of the chain (2), the belt holding frame (5) is turned upward at the position of the gear ring (3-1) at the lowest position. , the belt conveyor (
10), the transferred object (9) is received on the belt (7).

Since the belt (7) is formed in an L-shape on the belt holding frame (5), it is received in the bent pocket (30) and ascends the vertical ascending section (u-2), and eventually reaches the downward inclined ascending section. (
At step o-3), the object to be transferred (9) is gradually turned downward and ascends, and eventually becomes completely downward at the downward horizontal transition rotation section () I-4), so that the transferred object (9) that is being received falls. At that time, the transferred object (9) falls onto the transferred object conveyor belt conveyor (11) provided in the section and is carried out.Then, the belt holding frame (5) rotates at the position of the drive gear (23). While turning upward, the upward horizontal transition part (
H-5), moves to the vertical descending section (H-6) at the next gear wheel (3-5), and moves to the oblique ascending section (+1) at the next rotating gear wheel (3-6). -1), the conveyed object (9 ) is placed on the belt (7).

When the belt (7) changes from downward to upward at the position of the lowest tooth @ (3-1), the distance between the front horizontal frame members (6) of the belt holding frame (5) located in the front and rear positions is the maximum. The rotating belt (7), which is formed into an L-shape, extends in a straight line because it opens at the limit, but when the belt (7) is in the upward upward transition position, the belt holding frame (5) is at an acute angle to the chain (2). Since the belt (7) moves (acts) so as to return to its original shape, the linearly extending belt (7) bends into an L-shape.

At this time, if the belt (7) is made by Reimu, the creases (12) are provided in advance, which helps the belt (7) to restore its L-shape.

Also, a belt made of a flexible material with a rubber tube having a certain wall thickness (7)
In this case, since the rotating tool (12') is provided as an L-shaped bending mechanism, the L-shaped backward action of the belt (7) is smoothed. Furthermore, a rotating belt pusher (28) as an L-shaped bending biasing mechanism (16) for the belt (7) is installed close to this part, and its rotating rod (29) pushes the belt (7) to the chain (2). ) side, it is possible to easily return to the L-shape, and if an air nozzle (13-2) is provided, the compressed air helps the belt (7) to return to the L-shape. In addition, if the belt (7) is a fine mesh that is convenient for transporting small fish, the vertically rising part (
If the air nozzle (13-1) is installed near the top of the belt (H-2) and configured to blow compressed air onto the belt (7), the conveyed material ( small fish) in the bending pocket (30) of the L-shaped belt (7).
).

Furthermore, the downward horizontal transition part (H-4) of the belt (7) of the material concerned
If the air nozzle (13) is provided on the back side of the belt (7) at a position close to the downward rotating part of the drive gear wheel (23), compressed air can be blown from the back side of the fine mesh belt (7). Small fish attached to the fine mesh net (7) can be completely dropped onto the conveyor belt conveyor (11).

In addition, when the chain swing prevention device (15) is attached, since the gap between the belt (7) and the chain prevention device (15) is extremely small, it is necessary to suppress the chain (2) from swinging back and forth and from side to side. ) does not sag.

The rotation speed of the belt (7) is adjusted by controlling the rotation of the motor with a rotation regulator (31) of the motor (22).

Further, the support frame (21), together with the support column and the support member (17), completely supports the belt conveyor, and its both side plates (1
8) prevents the transported object (9) from scattering to the left and right. Further, the bottom plate (19) functions to guide the cleaning water from the washing nozzle (14) and the washed-off substances attached to the belt (7) to fall downward without scattering them elsewhere.

(d) Effects of the invention Since the present invention has the above-described structure and function, it is extremely convenient for transferring objects from the bottom to the top, especially in narrow spaces, and especially for small fish boiled on the first floor. When transferring to the drying room on the second floor, use a fine-mesh screen (7) to drain water well and do not require manual labor to transfer the material. Can be transported and dried. Therefore, the conventional heavy labor of manually transporting box-shaped objects is freed. Also, if you use the water washing nozzle (14), it is possible to keep the belt (7) clean at all times, and when you use the air nozzle (13) (13-1), you can almost completely remove small fish from the fine mesh net. The conveyed material can be transferred from the belt to the conveyor belt (11).

Next, even if Bell I-(7) is made of flexible material, it is possible to reliably transport objects from the bottom to the top, and there is no need to install multiple conventional belt conveyors in a row, and there is no space to install them in a row. It is extremely convenient. Also, there is no need for a conventional packet-type belt conveyor.

Furthermore, the installation interval of the belt holding frame (5) can be freely adjusted depending on the type of the transferred object, and the rotation speed can also be freely adjusted to adjust the transfer efficiency, which has many advantages.
