Abstract

PURPOSE:To obtain a weighing conveyor regardless of weighing accuracy by a crew chief of the conveyor without receiving disturbance such as the influence of the drop impact force of an object to be weighed by supporting pivotally freely rotatably one end of a weighing frame on a main body frame and supporting suspendibly the other end by a load cell. CONSTITUTION:The main body frame 2 is fixed and only the weighing frame 3 is supported suspendibly by the load cell 10 with a pivotal fulcrum 4 of the main body frame 2 and the weighing frame 3 as a fulcrum and a spot where the object to be weighed drops is made the optional position on the fixed main body frame 2. The object to be weighed cut out by a hopper C drops on the fixed main body frame 2 and is conveyed on the weighing frame 3 by a belt 7 and the gross weight of the object to be weighed mounted on the weighing frame 3 is detected by the load cell 10. A weight 9 supports the weighing frame 3 almost horizontally in a no-load state with a pivotally supporting pin 4 as the fulcrum.

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention is a weighing conveyor that measures the weight of an object placed on a conveyor belt while conveying the object.

(B) Prior Art Conventionally, as shown in FIG. 2, there is a weighing conveyor known as a single-bearing system, in which the falling point of the object to be weighed is set as the fulcrum A of the conveyor, and the load at one end is detected by a load cell B.

(c) Problems to be Solved by the Invention In the weighing conveyor shown in Fig. 2, the objects to be weighed are placed at the fulcrum point A in order to reduce the impact of the falling impact of the objects cut out from the hopper 〇. I'm trying to make it fall. However, in measurements that require high precision, movement of the falling point of the object to be weighed also causes an increase in errors. In addition, this weighing conveyor cancels the tare load using the tail pulley D and weight E, which also serve as balance weights, and attempts to weigh items from low to high capacity, and is exclusively used for weighing conveyors with short lengths. However, it has the disadvantage that it is not suitable for long conveyors that also serve as conveyors.

In view of the above-mentioned points, the present invention proposes a weighing conveyor that is free from external disturbances such as the influence of falling impact of objects to be weighed, and in which the length of the conveyor is not related to weighing accuracy.

(F) Embodiment 1 is a weighing conveyor, and the conveyor frame of the weighing conveyor is composed of a main body frame 2 and a weighing frame 3. In the weighing conveyor 1 of the present invention, the weighing frame 3 is pivotally supported by a pivot pin 4 to the main body frame 2 and is rotatable in the A-A direction. The weighing frame 3 measures the weight of the object to be weighed, and the length of the weighing frame 3 is determined as appropriate. If the conveyor has a long length, it will be placed at the end of the conveyor in the feeding direction.

(G) Effect The weighing conveyor l of the present invention has a conveyor frame composed of a main body frame 2 and a weighing frame 3, and is rotatable relative to the main body frame 3 to which the weighing frame 2 is fixed. The free end of the weighing frame 3 is suspended and supported by the load cell 10 using the pivot point 3 as the fulcrum, and the weight of the object to be weighed placed on the weighing frame 3 is detected. The object to be weighed may be dropped at any arbitrary position on the object 2, and the impact force of the fall of the object to be weighed does not become a disturbance factor for the measurement accuracy.

Furthermore, since only the weighing frame 3 at the tip of the weighing conveyor 1 is suspended and supported by the load cell IO, the length of the conveyor can be set to any length, and the length of the weighing frame 3 can be adjusted regardless of the length of the conveyor. Since the length can be made almost constant, the tare load can be canceled and removed with weight 9.
This is a practical device that can be expected to perform highly accurate measurement from low to high capacity.
