KR200225927Y1 - Drive-roller of belt-conveyor for checkweigher - Google Patents

Abstract

The present invention relates to a belt conveyor, which is a conveying device of an automatic checkweigher that measures the weight of a product in a industrial production line, and in particular, a driving roller that reduces manufacturing costs by increasing the coaxiality of processing and assembly and reducing the burden of inventory by using parts in common. It is about.

To this end, the present invention supports a shaft by inserting bearings at both ends of the roller drum, and drives the pulley coupling and the driving pulley to one side end of the roller drum. Make sure that only the rollers and rollers rotate.

In this way, the drive roller with the bearing inserted in the roller drum and the drive pulley mounted with the drive pulley coupling can increase the accuracy of coaxiality and share the driven roller with the parts.

Description

Drive-roller of belt conveyor of automatic checkweigher {{Drive-roller of belt-conveyor for checkweigher}

The present invention relates to a driving roller of a belt conveyor which is a conveying device of an automatic checkweigher for weighing a product during conveyance of a product in an industrial production line.

In general, the belt conveyor for automatic checkweigher has a driven roller (21) for adjusting the meander on the opposite side to the drive roller (20) receiving power from the motor as shown in Figure 3, the frame for supporting them to form a conveyor ( 23) and the belt 22 is hung between the two rollers.

The driving roller 20 is composed of a roller drum and a shaft, which is supported by a bearing mounted on a frame, and a timing pulley is inserted into the shaft passing through the bearing and fixed using a key. At this time, when power is transmitted to the timing pulley inserted into the shaft, the roller drum and the shaft rotate together.

In addition, the driven roller 21 uses a method in which the belt 22 meander adjusting device is fixed to the shaft so that the shaft is fixed and only the roller drum is rotated, or the meander adjusting device is fixed to the bearing housing so that the shaft and the roller drum are fixed. There is a way to rotate together.

However, the driving roller has a bearing that the outside of the roller has a strong left and right movement, it is difficult to match the coaxiality and the right angle, and the parts compatibility with the driven roller is inferior.

The main purpose of the present invention is to insert the bearing inside the roller roller of the driving roller to increase the accuracy of coaxiality and squareness, and to reduce the manufacturing process by sharing the driven roller and the component material.

In order to achieve the above object, the roller drum according to the present invention has the same structure as the driving roller and the driven roller to share the components and inserts bearings on both sides of the roller drum to increase the accuracy of coaxiality and squareness.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 1 shows the assembly relationship of the drive roller according to the present invention, by inserting the bearing (2) (3) on both sides of the roller drum (1) to support the shaft (4), the roller roller (1) The drive pulley coupling (5) is fastened to one side of the) to connect the drive pulley (6) and the roller drum (1).

When assembling the drive pulley coupling 5 and the roller drum 1, the outer diameter of the drive pulley coupling 5 is inserted into the bearing insertion portion of the roller drum 1 with a guide jaw to maintain the coaxiality. In addition, the inner diameter of the drive pulley coupling 5 processes the female thread so as to be screwed with the drive pulley 6. At this time, the driving pulley 6 and the driving pulley coupling 5 also give the uneven guide jaw to maintain the coaxiality, and the center of the driving pulley 6 passes through the hole so that the shaft 4 passes.

As described above, the driving roller of the present invention causes the driving pulley 6 and the roller drum 5 to rotate while the shaft 4 is fixed when power is transmitted from the motor.

2 shows the assembly relationship of the driven roller, and is made by removing the drive pulley coupling 6 and the drive pulley 5 fastened to the roller drum 1 in the drive roller of FIG.

As is apparent from the stated technical contents, the drive roller of the present invention has improved the coaxiality around the shaft and the right angle between the bearing and the roller drum, and the drive roller is additionally equipped with a drive pulley coupling and a drive pulley on the driven roller. By lowering the parts inventory burden by realizing the roller's parts sharing.

Claims (1)

After inserting the bearings on both sides of the roller drum, assemble the shaft on the inner ring of the bearing, and fasten the driving pulley coupling on one side of the roller drum with coaxiality with the uneven guide jaw and screw the driving pulley outward of the driving pulley coupling. Tightened driving roller.
