There are structural inconveniences such as

SUMMARY OF THE INVENTION It is an object of the present invention to provide a descending braking device configured to raise or lower each article guide member of a zigzag chute from the lower end by a flexible member without shifting. , for this purpose, the lifting mechanism is provided with a winding mechanism for winding the belt, which is placed in the middle of both sides of the article guide member, and is mounted directly on the output shaft of the reduction gear driven by the motor. It is configured as follows. This descent braking device has important advantages in that it is simplified due to its light weight construction, with some parts omitted, and that the descent braking device is suspended from the belt conveyor.

Embodiments of the present invention will be described in detail below based on the accompanying drawings.

The descent braking device 1 used when loading articles into the storage tank 2 of the vehicle 3 shown in FIG. Console 4 secured to frame 6 of conveyor 7 with bolts 5
(console). The funnel 9 is suspended on the console 4 via two latches 10 formed by chains and forming an acute angle with each other. Therefore, although the funnel 9 is hung flexibly, it occupies a central position below the tip of the belt conveyor 7. The funnel 9 includes a frame 12, and a tapered outer wall portion 13 is secured to the bottom of the frame 12.

The article lowering braking device 1 comprises a suspension mechanism consisting of two flexible members formed by a belt 11. Preferably a narrow weave belt with a width of 2 to 3
It is better to use cm. The upper end of this belt 11 is suspended from the framework 12. The descent braking device 1 has a plurality of frames 14 pivoted in a zigzag manner, and these frames 14
is suspended from the two belts 11 at the center of the frame by a threaded bolt 15 having a guide ring 16. To do this, the threaded bolt 15 must be attached to the frame 1.
4 and the article guide member 18 supported thereby is anchored in a predetermined hole 17 in the belt 11 at a location such that the article guide member 18 supported thereby occupies the corresponding oblique position to be processed. Each article guide member 18 consists of a belt suspended from the frame 14 at its two edges 19 and at its top edge from a pivot bar 21, the two frames 14 from which this belt is suspended pivotingly attached to each of the other frames 14. It is connected. The uppermost frame 14 is pivotally suspended from the framework 12 of the funnel 9.

Furthermore, the framework 12 of the funnel 9 is shown in FIGS. 4 to 7.
As shown in the figure, a winding mechanism driven by a motor 23 and constituted by a flat drum 22 of a lift mechanism 24 is supported in front of its framework (fourth
(see figure). The lowermost frame 14 is suspended from a lift mechanism 24 by two flexible members guided through a guide ring 16.

The two flexible members are comprised of two belts 26 connected via a connecting member 34. The flat drum 22 has a central passage for passing a connecting member 34 located between two belts 26 extending from opposite sides.

In practice, the two belts 26 and the connecting member 34 form a continuous fine-weave belt section with a width t of 2 to 3 cm. The drum 22 is driven by a motor 23 and is disposed on the output shaft of a speed reduction device constituted by a worm case 25.
Therefore, the bearing 43 of the worm case 25 functions as a bearing for the drum 22.
This is possible without risk. That is, by virtue of the fact that the two belts 26 exert the same tension in opposite directions on the shaft 36 and compensate for each other, the shaft 36 is only loaded torsionally, but hardly subjected to bending loads. . In the unwound position the connecting member 34 is able to move itself radially within its passage 35, so that differences in the elasticity of the belt 26 are then automatically corrected. At each position of the descent braking device, that is, at each winding of the belt 26, the belt 26 takes on a spiral shape and is shortened equally by winding around each other. Each belt 26 driven from the drum 22
passes through two guide rollers 37 and 38 supported by the frame 12.

By arranging the lifting mechanism 24 in front of the framework 12, it is also possible for another belt conveyor 39 to drop the articles onto the lowering brake device 1. Preferably, the lift mechanism 24 is covered by a plate 40. It is also possible to arrange the lift mechanism 24 below the belt conveyor 7. The descent braking device 1 according to the invention can be made lightweight and therefore allows articles to be conveyed by slightly bending the frame 6 of the belt conveyor 7. Lift mechanism 24
is provided with a switch 41 fixed to the front surface of the frame 12 for stopping the motor 23 depending on the degree of winding of the belt 26. In the situation where belt 26 is fully deployed, pivoted deflection sensing element 42 is in the position shown in solid lines in FIG. The motor 23 is therefore blocked further in the unwinding direction. Thus, the switch 41 switches the sixth switch to prevent the winding of the belt 26.
The motor 23 is stopped at the position of the deviation sensing element 42 shown by the dotted line in the figure.

Article guide member 18 for guiding articles
are directed downward, and the guide members 18 (except for the uppermost guide member) are suspended so as to alternately face each other.

1 and 2 show that sensitive parts such as potatoes, vegetables, etc. can be transported to a considerable depth in the storage tank 2. Storage tank 2
As the level increases, the belt 26 shortens while the frame 14 overlaps the frame 14 above it. During this movement, as the angle of inclination b of the guide member 18 towards the horizontal plane C increases, the articles easily move away from the last drawn article guide member 18 without the risk of crowding. . The article guide members 18 connected to the raised frame 14 extend in a staggered manner closely parallel to each other so as not to obstruct the passage of articles. (See Figure 5) For this purpose, the guide member 18 must be rotated from 50° to 90°.
The angle W is formed in the frame 14, preferably at 70°. In fact, the article falls across the frame 14.

In the raised position shown in FIG. 5, the lowering brake device 1 has a height h and an unobstructed path for the passage of articles. and the use of flexible suspension mechanisms such as chains 10 and belts 11 and
Damage to the descent braking device 1 is avoided by utilizing the pivotally connected frame 14 of the shape.

The lift device can be automatically and continuously controlled by a lever scanning device (not shown).

As a brake bag filled with articles, the lowering brake device 27 or 28 shown in FIGS. 8 and 9 can be used. The lowering braking device 27 shown here is such that each article guide member 29 is formed by a trough of sheet material;
This differs from the above-mentioned descent braking device in that the size of the bag is configured to allow braking.

On the other hand, the descent braking device 28 is distinguished from the aforementioned descent braking device 27 in that each guide member 30 is formed of a lattice 31, and a roller 32 is rotatably journalled on the lattice 31. .

Although preferred embodiments of the present invention have been described above, other specific configurations can be variously modified without departing from the spirit and scope of the present invention. Since the present invention has the above-mentioned configuration, the flexible member is wound up by driving the motor according to the height of the accumulated fallen articles, and the frame and article guide member are sequentially stabilized from below. It is something that can be pulled up, and in the end it can be pulled up to fold everything up.
