Abstract
The present invention relates to an apparatus for controlling the warp and weft of a belt conveyor, comprising a first roller frame disposed on a moving frame and provided to support a lower roller, and a second roller frame disposed in an upper seating groove of the first roller frame, And a load cell provided in the seating groove and provided to measure a load transmitted to the second roller frame. According to the present invention, the load cell can be used to measure the load of the object to be conveyed The belt conveyor can be stably and efficiently operated by sensing the enemy and detecting the meandering of the belt by using the position detection sensor and controlling the belt.
Description
More particularly, the present invention relates to a device for detecting a deviation of a conveyed object by using a load cell and sensing a meander of the belt using a position detection sensor, And more particularly, to a meandering and unidirectional control device of a belt conveyor that can operate efficiently.
Usually, the belt conveyor is disposed on a moving plane, and a plurality of rollers are arranged vertically to perform a movement like an endless track and to transfer a large amount of conveyed objects to a position desired by an administrator.
Such belt conveyors are used in various industrial fields such as movement of finished products such as automobiles, transfer of powdery materials such as iron ore, coal, and courier classification. At this time, the belt used for the belt conveyor is made of a rubber material, and a steel cord is inserted between the rubber materials to prevent abrasion due to contact with the conveying object and to maintain tension.
However, when the belt conveyor is used, a problem of skewing occurs in which the belt is displaced from the roller in a predetermined position. A conventional technique for improving such a skew problem is disclosed in Korean Patent Laid-Open No. 10-2015-0076018 shown in Fig.
1, both sides of the
At this time, the
However, this structure is disadvantageous in that it is impossible to quantitatively and precisely detect the degree of meandering. Further, when the object to be conveyed is placed on a belt, the object to be conveyed moves on the belt. However, there is a problem that the conventional art can not solve the problem.
Therefore, there is a need for a technique capable of simultaneously solving the problems of belt conveyance and belt conveyance.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art as described above, and it is an object of the present invention to provide a position sensor that senses a movement of a conveyed object using a load cell, And a belt conveyor device capable of stably and efficiently operating the belt conveyor.
According to an aspect of the present invention, there is provided an apparatus for controlling skew and slip of a belt conveyor, including a first roller frame disposed on a moving rail and provided to support a lower roller, A second roller frame disposed to support the upper roller, and a load cell disposed in the seating groove, the load cell being provided to measure a load transmitted to the second roller frame.
In addition, the embodiment of the present invention may further include a displacement control means disposed on the second roller frame so as to prevent the transported object from being shifted and moved to one side of the belt.
Further, in the embodiment of the present invention, the displacement control means includes a pair of drive motors facing the belt and disposed at the upper end of the second roller frame, and a drive shaft connected to the shaft of the drive motor, And a pair of adjustment bars provided to adjust the position of the object to be conveyed on the belt.
Further, in the embodiment of the present invention, the control bar is provided in a curved shape, and may be configured to be bent in an outward direction of the belt.
In addition, in the embodiment of the present invention, the upper end of the control bar may include a bent portion, and the bent portion may be configured to be bent inward of the belt.
Further, in the embodiment of the present invention, it is possible to further include a skew control means disposed on the moving structure to detect skewing of the belt and to control skewing of the belt.
Further, in the embodiment of the present invention, the skew control means includes a pair of hydraulic cylinders disposed opposite to both ends of the belt and disposed on the moving plane, and a pair of hydraulic cylinders disposed on the rod ends of the pair of hydraulic cylinders And may include a platen disposed therein.
In addition, the embodiment of the present invention may further include a rolling roll disposed on the pressure plate to prevent abrasion of the belt when the belt is contacted.
In addition, the embodiment of the present invention may further include a pair of position detecting sensors disposed on the moving leg facing opposite ends of the belt so as to sense the skew of the belt.
According to the present invention, by arranging the load cells on the right and left sides of the roller frame of the belt conveyor, it is possible to easily detect whether or not the object is knitted by the pressure difference applied when the object to be conveyed is knitted on the belt.
In addition, when a piece is detected, a control bar is operated by using a driving motor, so that the object to be conveyed on the belt can be pushed toward the center of the belt and the deviation can be mitigated.
Further, by locating the position detecting sensors on the left and right sides of the roller frame of the belt conveyor, it is possible to quickly detect the skew of the belt by measuring the distance to the belt.
Further, when the belt skew is detected, the hydraulic cylinder can be operated to normalize the position of the belt by pushing the belt to the opposite side of the skew by a predetermined interval.
This can ultimately prevent breakage and operation errors of the belt conveyor. As the knitting and belt skewing are suppressed, the conveyance of the conveyed object is facilitated and the fall of the conveyed object to the peripheral portion is alleviated to enable stable and efficient operation of the apparatus. So that contamination can be prevented.
