ける走行ベルトの蛇行を修正する装置の改良に関
する。[Detailed Description of the Invention] This invention relates to an improvement of a device for correcting meandering of a running belt in a conveyor device using a belt.
この種のベルト蛇行修正装置として、これまで
のものは検出部を修正ローラーに直結させてこの
検出部を蛇行ベルトで押して修正ローラーを直接
抉じ回すものであるため、走行ベルトと摩擦接触
している修正ローラーを回動させるには非常に大
きな力が必要であり、その力の抵抗がベルト側辺
部と検出部との接点に表われてベルトの側辺部を
傷めベルト全体の耐久性を妨げる。 Conventional belt meandering correction devices of this type have a detection part directly connected to the correction roller, and the detection part is pushed by the meandering belt to directly twist the correction roller, so there is no frictional contact with the running belt. An extremely large force is required to rotate the correcting roller, and the resistance to that force appears at the contact point between the belt side and the detection unit, damaging the belt side and reducing the durability of the entire belt. hinder.

つてしまつた状態での修正稼動であるため、修正
ローラーを回動させるのに非常に大きな力と時間
がかり、迅速且つ確実にベルト蛇行を修正するこ
とが極めて困難であつた。 In addition, as a conventional device, the detection part is placed downstream of the correction roller along the running direction, and the belt meandering trend is detected downstream of the correction roller while it is running, and the information is transmitted to the correction roller and rotated. However, since the correction operation is performed after the sensor has already passed the correction roller and the meandering width and its pushing force have increased, the frictional resistance with the detection part has increased. It takes an extremely large amount of force and time to rotate the rollers, making it extremely difficult to quickly and reliably correct belt meandering.

た。 Moreover, since the rollers of these conventional meandering detection parts have flat outer peripheral surfaces, the left and right sides are pressed against the detection roller in an upright manner by the meandering force while the belt is running, causing them to bend and bend toward the belt side. There were various runner-up points, such as damaging the edges and not being able to accurately transmit the meandering pushing force to the correction roller.

The figure is a plan view of the main part showing an embodiment of the elbow arm part, and Fig. 9 is a plan view of the main part showing an embodiment of the detection roller. A bearing hole a is provided in the center of the support frame 1 of the correction roller 2, and the rotating shaft b protruding from the center of the lower surface of the support frame 3 of the correction roller 2 is fitted into the bearing hole a. It is mounted so as to be able to rotate horizontally with respect to the support frame 3, and is rotatably supported on the left and right ends of the underframe 1 by trochanters C, C provided at the lower sides of both ends of the support frame 3 and sliding in the front and rear direction. Reference numeral 4 designates an elbow arm part, the trunk of which is bent into an inward L-like shape to form an elbow piece having an elbow part d, and a detection roller 7 is attached to the distal end part e. An elbow portion d is pivotally connected to either the left or right end of the underframe 1 near the left or right end thereof by a support shaft f so as to rotate horizontally;
Near the other end, the trunk of a cut-off elbow arm part 4 without an elbow piece is pivotally connected by a support shaft f', and their neck parts are connected by a rod 8 for interlocking movement. Of the elbow arm parts 4, 4 installed between the underframe 1 and the support frame 3 in this way, the underframe 1
The downward protrusion h of the outer end of the operating rod 5 is pivoted adjacent to the upper part, and the guided protrusion k provided on the lower surface of the correction roller support frame 3 is engaged with the guiding groove j of the inner end of the operating rod 5. When the belt 6 is about to meander, the detection roller 7 on the side that is trying to move toward the outside is pushed outward by the belt side portion, so that the elbow portion d of the elbow arm portion 4 is pushed outward.

It is also possible to rotate the correction roller support frame 3 by providing operating rods 5, 5 which are respectively hooked.
In addition, in the interlocking mechanism for rotating the correction roller 2, the elbow arm part 4 is moved to the elbow part d as shown in FIG.
A guiding groove (guiding hole) j' is provided, and its elbow piece is pivotally connected to the supporting shaft f, and a guided protrusion k of the correction roller support frame 3 is engaged with this guiding groove (guiding hole) j'. The operating rod 5 can be omitted. Both the guide hole i of the elbow arm portion 4 and the guide groove j of the actuating rod 5 are formed in a horizontally elongated manner so as to sufficiently absorb expansion and contraction during the interlocking movement.

の耐久性にも役立つ。 In this invention, the central part of the outer periphery of the detection roller 7 is recessed and formed into a pincushion shape, so that the detection roller 7 comes into contact with the side parts of the belt while pinching them from above and below. The side portions are prevented from rising upward and being bent, and the pressing force can be faithfully transmitted to the correction roller 2 to rotate it, and this also contributes to the durability of the belt.

By pivoting the center of the belt 0 to the tip e of the elbow arm 4 and attaching it in an oscillating manner, the meandering pushing force of the side part of the belt 6 that is applied to each pair of detection rollers 7, 7 can be reduced. By utilizing this, the contact surface changes back and forth like a seesaw, giving the contact surface flexibility that can be received immediately in response to the displacement of the side portion of the belt 6, and at the same time, the pressing force from the side portion of the belt 6 is applied by two The detection rollers 7, 7 are equally divided to prevent local damage to the side portions of the belt 6.

の発生する虞れがないことなどから有効である。 Furthermore, it goes without saying that by moving the detection roller 7 upstream of the correction roller 2, the correction effect becomes greater, but in the relationship between the meandering correction device A and the conveyor device, the correction effect may differ depending on the installation location. I discovered something.
That is, in the end rollers (driving roller 9 and driven roller 9') for mounting the belt that are provided facing each other as shown in FIG. 1 and FIG. However, this area is at belt 6.
This is the location where the overall tension (load) and driving force are concentrated and the resistance is most strongly exerted, and the influence is particularly strong on the drive roller 9 section on the conveyance operation surface. Therefore, a very strong force is required to correct the meandering of the belt 6 at this location, and even if you try to apply too much force, it is actually impossible because the belt 6 itself will be damaged instead of correcting the meandering. . This tension force (load) and driving force create strong frictional resistance between the belt 6 and the driving roller 9 or the driven roller 9', and are strong in this part, and the range of influence is closely related to the width of the belt 6. I discovered that.
It was concluded that the most effective installation location is a point M' upstream of approximately two to three times the belt width M from the fulcrum of the end rollers (drive roller 9, driven roller 9'). Therefore, by equipping all or some of the end rollers, the meandering of the belt 6 can be accurately corrected with a smaller force at this point, and moreover, these tension forces (loads) This is also effective because there is no possibility that the drive roller 9 or the driven roller 9' will meander again due to the relationship with the driving force.

の実用的効果を奏する。 With this configuration, the detection rollers installed on the left and right sides of the running belt are connected to the correction rollers that are rotatably supported, and the detection rollers are pushed together by the pushing force of the meandering belt, and the correction rollers are moved. This is a device that corrects meandering by rotationally displacing the belt and using the principle of the running angle of the belt with respect to the correction roller. This elbow arm is pivotally mounted on the underframe which pivotally supports the correction roller support frame, and the elbow piece or elbow portion is engaged with the correction roller support frame to rotate the correction roller. This elbow portion acts as a lever and allows the correction roller, which is in contact with strong frictional resistance, to be easily rotated, resulting in a smooth angle change. Therefore, the frictional resistance at the belt side parts is reduced, damage to this part is minimized, and the durability of the belt is increased, and the rotational displacement angle of the correction roller is amplified by the lever action. A large meandering correction angle is obtained, which has practical effects such as allowing the correction process to be carried out extremely quickly.
