Abstract

PROBLEM TO BE SOLVED: To change a conveying angle by bending a line of belt conveyor in the middle by preventing looseness of a flat belt as a presser roller transversely moves along a transversing frame in accordance with change of inclination against the transversing frame of an inclined delivery frame. SOLUTION: A cross slot 28 of a bracket 27 to pivotally support a presser roller 6 is installed on a transversing frame 1 free to transversely slide, and an arc slot 29 is fixed on an inclined delivery frame 2 by a bolt 30. When the inclined delivery frame 2 is inclined by loosening the bolt 30, the bracket 27 transversely moves along the transversing frame 1, and accordingly, the roller 6 also moves left and right and tightening of a flat belt 5 is not loosened. As a good shape of the arc-shaped slot 29 regulates transverse moving quantity of the presser roller 6, proper tension is applied on the flat belt 5. A driving motor 31 transmits motive power to an axis of rotation of a roller 3 by a chain 32.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor device for transporting articles placed on a flat belt, in which the feed angle is changed in the course of the transport, and the article is fed upward by performing a horizontal feed to an inclined feed. Things.

[0002]

2. Description of the Related Art In general, conveyors which wrap a flat belt around a roller provided at a transport starting end and a roller provided at a transport ending side, place articles on the flat belt, and transport the articles are generally linearly transported. I have. When the transfer direction or the transfer angle is changed during the transfer, a second transfer belt conveyor having a different transfer direction is provided following the first transfer belt conveyor.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to change a conveying angle by bending a series of belt conveyors in the middle without using separate belt conveyors.

[0004]

According to the present invention, a flat belt 5 is wound around rollers 3 and 4 provided at both ends of a transverse feed frame 1 and an inclined feed frame 2 connected to bendable, and a pressing roller 6 is attached to a connecting portion. In the conveyor device in which the flat belt 5 is moved along the feed frame 1 and the inclined feed frame 2, the holding roller 6 is driven by the pressing roller 6 as the inclination angle of the inclined feed frame 2 with respect to the horizontal feed frame 1 is changed. The transport angle can be changed so that the flat belt 5 does not loosen due to lateral movement along the line.

[0005]

The conveyor apparatus of the present invention is constructed by winding a series of flat belts 5 around rollers 3 and 4 provided at both ends of a horizontal feed frame 1 and an oblique feed frame 2, so that the conveying direction is changed. Can be performed more easily than a configuration in which separate conveyor devices are connected.
When the inclination angle is changed with respect to the flat belt 5, the flat belt 5 is loosened or becomes too tight. In the present invention, however, the flat belt 5 is optimal because the pressing roller 6 moves laterally with the change in the angle of the oblique feed frame 2. Will be maintained.

[0006]

Next, an embodiment of the present invention will be described with reference to the illustrated vegetable bagging machine. The overall structure is such that a bag holding mechanism 12 is provided in an opening 11 at the upper center of a square box-shaped
0, a bag container 13 in which empty bags are stacked and stored, and a take-out arm 14 for taking out empty bags are provided. A chute 15 is provided from below the bag container 13 to a lower side of the machine frame 10. The conveyor device 8 of the embodiment of the present invention is provided at the lower end so that the packed vegetables are lifted outside the machine and carried out into the container 16.

On one side of the upper part of the machine frame 10, there is provided a spraying mechanism 17 for spraying water into an empty bag in a mist state. The spraying mechanism 17 includes an electric cylinder 18 and a bag holding mechanism 12.
A spray nozzle 19 is provided so as to project toward the center of the blower.
Are connected by a pipe 22 to spray water in a mist state when projecting above the empty bag. Reference numeral 23 denotes a constant-rate discharge pump for discharging water at a constant rate.

When the bag container 13 moves below the opening 11 inside the machine casing 10 and the take-out arm 14 rotates to take out the empty bag in the bag container 13, the bag container 13 returns to the original position. Returning, the take-out arm 14 stands up, the empty bag is opened by the opening arm 24, the bag holding rod 25 is engaged with the bag mouth, and the empty bag is hung in the open state. After spraying water in the empty bag suspended in the open state, the operator inserts leaf vegetables such as horen grass held by hand into the bag mouth. Thereafter, the bag holding rod 25 rotates inward and drops the bag full of vegetables. The vegetable bag slides on the chute 15, rests on the horizontal portion of the conveyor 8, and is sent into the container 16.

[0009] The conveyor 8 can adjust the inclination of the inclined portion,
When not used, it stands up along the side surface of the machine casing 10. The structure of the conveyor 8 is as shown in FIG.
The horizontal feed frame 1 and the inclined feed frame 2 are connected by a support shaft 26 so as to be bendable, and a flat belt is formed on a roller 3 pivotally supported at the tip of the lateral feed frame 1 and a roller 4 pivotally supported at the tip of the inclined feed frame 2. The flat belt 5 is wrapped around the support shaft 26 and the right and left sides of the flat belt 5 are pressed by the pressing roller 6 so that the flat belt 5 is moved in the transverse feed frame 1 and the inclined feed frame
And along.

A bracket 27 for pivotally supporting the holding roller 6
Is that a horizontally elongated hole 28 is slidably mounted on the transverse feed frame 1 and an arcuate elongated hole 29 is fixed to the inclined feed frame 2 with bolts 30. When the bolt 30 is loosened and the inclined feed frame 2 is inclined, the bracket 27 is tilted. Moves laterally along the lateral feed frame 1, and accordingly, the pressing roller 6 also moves right and left, so that the tension of the flat belt 5 is not loosened. Since the groove shape of the arc-shaped long hole 29 regulates the amount of lateral movement of the pressing roller 6, an appropriate tension is applied to the flat belt 5. A drive motor 31 transmits power to the rotation shaft of the roller 3 by a chain 32.
