Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a belt conveyor having an uneven loading and belt serpentine,

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.

At this time, the meandering sense unit 40 and the meandering orthogonal unit 30 are disposed between the pair of the driving rollers 10. The meandering sense unit 40 detects the width direction of the belt 20, And the driving unit 33 which is a component of the meandering control unit 30 operates to rotate the supporting table 31 with respect to the supporting shaft 32 to move the driving roll unit 10 to rotate the belt unit 20 I will control the meandering.

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.

Korean Patent Publication No. 10-2015-0076018

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an apparatus for controlling skew and skew of a belt conveyor according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a front sectional view showing an embodiment of a skew and slip control apparatus for a belt conveyor according to the present invention, Fig. 3 is a plan view of the invention shown in Fig. 2, Fig. 4 is a partial enlargement FIG. 5 is a front sectional view showing an operating state according to the invention shown in FIG. 2, and FIG. 6 is a plan view showing an operating state according to the invention shown in FIG.

Referring to FIGS. 2 to 4, an embodiment of the apparatus for controlling skew and slip of a belt conveyor according to the present invention includes a first roller frame 140, a second roller frame 150, a load cell 400, And a yaw control means 500. [0034]

First, the first roller frame 140 is disposed on the moving equipment 160 and can be provided to support the lower roller 130. The second roller frame 150 may be disposed in the upper seating groove 143 of the first roller frame 140 and may be provided to support the upper roller 120. The belt 110 for conveying the object to be conveyed is placed on the upper roller 120 and is conveyed according to the rotation of the upper roller 120 and returns via the lower roller 130. Through such a structure, the belt 110 operates like an endless track and continuously conveys the conveyed object.

Since the upper roller 120 and the lower roller 130 can support the belt 110 and the object to be conveyed, the upper roller 120 and the lower roller 130 can be realized with a metal material having a high hardness, Since the roller frame 150 needs to support the upper roller 120 and the lower roller 130, the roller frame 150 may be made of a metal material having a high hardness.

Next, the load cell 400 may be disposed in the seating groove and may be provided to measure a load transmitted to the second roller frame 150. The load cells 400 may be arranged on the left and right sides of the belt 110 on the second roller frame 150 in a pair. The plurality of load cells 400 may be disposed on the second roller frame 150 to support the belt 110 along the conveying direction of the belt 110.

If the object to be conveyed is shifted to one side on the belt 110, the pressing force applied between the left and right load cells 400 is varied. The manager can set a preliminary specific reference pressure deviation range and can recognize that the object to be conveyed is shifted on the belt 110 when a value exceeding the specific standard pressure deviation range is received from the load cell 400. [

Of course, the first roller frame 140 and the second roller frame 150 supporting the belt 110 are arranged in plural along the longitudinal direction of the belt 110, The manager can confirm whether or not the object to be conveyed on the belt 110 is knitted with a plurality of roller frame installation intervals.

For example, assuming that 100 roller frames supporting the belt 110 are arranged at regular intervals in the longitudinal direction of the belt 110, 200 load cells 400 are provided on both sides of the belt 110, do.

At this time, if the manager sets the specific reference pressure deviation range to 20, it means that the transported object is not shifted on the belt 110 when the pressure deviation measured between the load cells 400 on both sides is 20 or less. Conversely, when the pressure deviation measured between the load cells 400 on both sides exceeds 20, it can be seen that the object to be conveyed is in a loose state on the belt 110.

Here, the basic pressure unit may be variously determined by 'Pa', 10 Pa, 100 Pa, kPa depending on the work environment to which the belt conveyor is applied, the size, weight and properties of the conveyed object.

Next, the displacement control means 200 may be disposed on the upper portion of the second roller frame 150 to prevent the conveyed object from being knocked and moved on one side of the belt 110. The displacement control unit 200 may include a driving motor 220 and an adjusting unit.

The driving motor 220 may be disposed on the left and right sides of the upper portion of the second roller frame 150 facing the belt 110. The driving motor 220 may be a stepping motor, a pulse motor, or the like. That is, it may be a motor that rotates the angle of the shaft 223 in proportion to a predetermined step or pulse set in advance. This allows precise angular adjustment of the rotation range of the control bar 250 according to the degree of deflection on the belt 110. [

The rotational angle range of the driving motor 220 can be individually preset by the operator depending on the width of the belt 110, the size, weight and nature of the object to be conveyed, and the work environment such as a portion on the belt 110, , And can be presented in various values.

Here, the shaft 223 of the driving motor 220 may be arranged in a vertical direction. The control bar 250 may be connected to the shaft 223 of the driving motor 220 and may be provided in a pair so as to adjust the position of the object to be conveyed on the belt 110 by moving in the direction of the conveyed object .

Although only one of the knob control means 200 is shown in FIG. 3, a plurality of knob control means 200 may be disposed at predetermined intervals along the length direction of the belt 110. Or may be locally disposed only at a portion where the piece is frequently generated depending on the working environment.

When the driving motor 220 is operated, the shaft 223 of the driving motor 220 is rotated at a predetermined angle in response to an operation such as a step or a pulse and is connected to the shaft 223 of the driving motor 220 The control bar 250 rotates in the direction of the belt 110.

3, the control bar 250 is connected to the shaft 223 of the driving motor 220 in a lengthwise direction, and may be provided in a curved shape, It may be curved outwardly.

6, the conveying object is smoothly pushed when the conveying object is pushed toward the center of the conveying belt 110, and at the same time, the conveying belt 110 is conveyed in one direction, So as to alleviate an impact applied to the control bar 250 when the object hits the object to be conveyed on the control bar 250. If the conveying object is provided in a curved shape on one side of the control bar 250, it smoothly flows along the curved line even when the conveying object hits it. Therefore, abrasion and breakage of the control bar 250 can be alleviated and sudden flow disturbance of the conveying object can be controlled .

In addition, on one side of the control bar 250 facing the belt, a wear-resistant coating or an anti-wear pad 600 may be attached to mitigate contact abrasion with the conveyance object. The wear-resistant pad 600 may be disposed along the longitudinal direction of the control bar 250.

At this time, a balance block 255 may be disposed on the other side of the control bar 250. Since the length of one side of the control bar 250 is longer than the length of the other side of the balance block 255, the entire balance of the control bar 250 is inclined toward one side of the control bar 250 Thereby preventing the user from losing.

Here, the upper end of the control bar 250 includes a bending portion 253, and the bending portion 253 may be provided by bending inward of the belt 110. If the object to be conveyed is a particulate material having a certain particle size as the bending portion 253 is bent toward the inside of the belt 110, the upper portion of the object to be conveyed is pushed toward the center of the belt 110, .

Next, the meandering control means 500 may be disposed on the moving facility 160 to sense the skew of the belt 110 and to control the skew of the belt 110. The meandering control means 500 may include a hydraulic cylinder 510, a rolling roll 517, and a position sensing sensor.

First, the hydraulic cylinder 510 may be disposed on the left and right sides of the moving facility 160 in a pair, facing opposite ends of the belt 110. The body of the hydraulic cylinder 510 may be fixed on the moving facility 160 by a bolt fastening method and the rod 513 of the hydraulic cylinder 510 may be placed in the direction of the belt 110. At this time, a pressure plate 515 may be welded or bolted to the ends of the rod 513 of the pair of hydraulic cylinders 510.

The pressure plate 515 may be disposed horizontally on the side surface of the belt 110 so that the side surface of the belt 110 may be pressed. The rod 513 of the hydraulic cylinder 510 to which the pressure plate 515 is connected is also aligned with a horizontal line on the side surface of the belt 110. [

Referring to FIG. 4, the rolling roll 517 may be disposed on the pressure plate 515 to prevent abrasion of the belt 110 when the belt 110 is contacted. The operator actuates the hydraulic cylinder 510 so that the pressure plate 515 connected to the end of the rod 513 of the hydraulic cylinder 510 is moved in the direction of the side surface of the belt 110 .

The belt 110 is continuously moving in the longitudinal direction because the object to be conveyed is being conveyed and when the pressure plate 515 is gradually moved to push the belt 110, the belt 110 is in contact with the side end face of the belt 110 at any moment , At which time the belt 110 is brought into contact with the rolling roll 517. Since the rolling roll 517 rotates at a speed corresponding to the moving speed of the belt 110, abrasion due to friction between the belt 110 and the rolling roll 517 is prevented.

Here, the position sensor senses whether the belt 110 meanders. The position sensing sensors may be disposed on the moving equipment 160 in pairs such that both ends of the belt 110 face each other.

Of course, the meandering control means 500 may be arranged in a plurality of positions at regular intervals along the longitudinal direction of the belt 110, so that the meandering control means 500 can be configured to correct skewing locally when a meandering occurs in a specific region. Alternatively, it may be disposed on the path of the belt 110 in which meandering occurs mainly according to the working environment.

The manager can set a reference distance range of the belt 110 in advance, and when the belt 110 approaches the predetermined reference distance of the belt 110, the controller 110 transmits the belt 110's reference distance range. The manager actuates the hydraulic cylinder 510 according to the signal of the position sensor to correct meandering. At this time, the manager can calculate the moving range of the hydraulic cylinder 510 rod 513 by proportionally analyzing the proximity distance transmitted from the position sensing sensor.

The controller may further include a driving unit 330, a pressure measuring unit 310, and a control unit 320. The driving unit 330 may be provided to operate the hydraulic cylinder 510 and the driving motor 220. The pressure measuring unit 310 receives a signal from the load cell 400 and transmits the signal to the belt 110 ) Can analyze the pressure deviation between the load cells 400 on both sides.

The control unit 320 receives a signal from the pressure measuring unit 310 and calculates a degree of deviation according to the pressure deviation and calculates a rotation value of the shaft 223 of the driving motor 220. Also, it can perform a function of calculating a movement range of the rod 513 of the hydraulic cylinder 510 by receiving a signal from the position sensing sensor.

5 and 6, an operation state according to an embodiment of the present invention is shown. When a piece of the conveyed object is formed on one side of the belt 110, the second roller frame 150 is disposed at the lower end of the second roller frame 150 A pressure deviation occurs in the pair of load cells 400. The pressure deviation measured by the load cell 400 is transmitted to the pressure measuring unit 310.

If the pressure deviation measured by the pressure measuring unit 310 deviates from the predetermined reference pressure deviation range set by the manager, it means that the object to be conveyed is out of the permissible deviation range on the belt 110, The control unit 310 sends a signal to the control unit 320.

The control unit 320 calculates a rotation angle of the control bar 250 by calculating a signal sent from the pressure measurement unit 310. When the rotation angle is calculated, the control unit 320 sends a signal to the driving unit 330 to operate the driving motor 220.

When the driving motor 220 is operated, the control bar 250 connected to the shaft 223 of the driving motor 220 rotates in the direction of the center of the belt 110. At this time, since the driving motor 220 can be implemented as a stepping motor, a pulse motor, or the like, the driving motor 220 can be gradually rotated toward the center of the belt 110 according to the unit of the set step or pulse.

6, it is confirmed that a conveyed object that is knitted to one side of the belt 110 flows along the curved surface of the control bar 250 and flows toward the center of the belt 110 according to the rotation of the control bar 250 . The above-described process controls the deviation on the belt 110.

Similarly, when the belt 110 meanders, it recognizes the approach distance from the position sensor and transmits it to the control unit 320. The control unit 320 calculates the degree of meandering through the approach distance, 510) of the load 513 is calculated. Then, the control unit 320 actuates the driving unit 330 to actuate the hydraulic cylinder 510, thereby pushing the side surface of the belt 110 to relax the meandering.

The embodiment of the present invention can reduce the deviation of the conveyed object on the belt and control the meandering of the belt through the above-described construction and operation.

The above description is only a specific example of the meandering and uneven control device of the belt conveyor.
