周知のとおり、運搬物の逆流や飛散などを防いだり、
また運搬物を急傾斜で運搬するために、トラフ形ベルト

ア等が知られている。As is well known, it prevents backflow and scattering of transported goods,
In addition, a cylindrical belt conveyor is used in place of the trough belt conveyor to convey goods on a steep slope. The cylindrical belt conveyor includes a lap-shaped cylindrical belt conveyor in which a plurality of shape-retaining rollers provided on the outer periphery of the flat belt form a flat belt into a circular shape, or a wrap portion of the wrapped cylindrical belt conveyor. There is known a palm-to-shape cylindrical belt conveyor or the like in which both ears are protruded outward, held between a pair of rollers, and the end surfaces of the ears are pressed by a single binaural pressing roller.

As shown in FIG. 4, the flat belt 1 has a plurality of shape-retaining rollers 2,
2 are rounded to form a circle, and the two ears 4, 4 are sandwiched between a pair of guide rollers 5, 5 in a palm-shape manner. It is pressed by the roller 6. The guide roller 5 and the binaural pressing roller 6 are rotatably supported by an integrated roller bracket 7. The shape retaining rollers 2 are rotatably supported by respective roller brackets 8. These roller brackets 7, 8 are mounted on a panel-shaped stand 9 so as to be adjustable in position. The panel-like stands 9 form a passage 10 through which only a cylindrical belt conveyor passes, and are arranged in a large number in the belt traveling direction.

伸張度に相違をきたし、ベルトが平ベルト１で構成され
ているだけにベルトの合掌部で耳ズレ（耳部の端面が上
下方向に齟齬する状態をいう）が発生する。By the way, such a joint-shaped cylindrical belt conveyor has a feature that it can be designed to have a predetermined radius of curvature with respect to the diameter of the cylinder so that it can be vertically and horizontally curvedly transported, and thus can be designed in a layout that can bypass an obstacle. On the other hand, in the case of lateral curve transportation, the degree of belt elongation is different between the inside and the outside of the convoluted cylindrical belt conveyor with the center of the radius of curvature as a point of view, and only the flat belt 1 is used for the belt. Ear misalignment (refers to a state in which the end faces of the ears are inconsistent in the vertical direction) occurs at the joint portion of the belt.

形成されると耳ズレが大きく発生する。In particular, when the flat belt 1 is installed so as to be curved laterally immediately after being formed into a cylindrical shape from a flat state, the trajectory of each of the trough-shaped ear portions that are not yet cylindrical is in plan view with respect to the belt center line. It becomes asymmetric, and if it is formed in a cylindrical shape in such a state, ear misalignment greatly occurs.

Then, the flat belt is developed by the tail pulley on a palm-shaped cylindrical belt conveyor in which the both ears are joined together by a pair of guide rollers and the end faces of the ears are pressed by a single both-ear pressing roller. The end faces of both ears of the trough-shaped flat belt gradually formed into a cylindrical shape from the pressed state are separately pressed by a pair of second ear holding rollers for preventing ear misalignment. 2
The ear-holding rollers for the two-wheeled cylindrical belt conveyor are characterized in that the ear-holding rollers are mounted on the stand via roller brackets so that they can be adjusted up and down separately to prevent the ears from shifting during curve transport. is there.

A pair of left and right long holes 16 and 16 are formed in 14a, and these long holes
A pair of ear deviation preventing roller brackets 17 are fixed to the respective 16 with bolts (not shown). This roller bracket
17 are also provided with two vertically long holes 19, 19,
Then, a bolt (not shown) is inserted into the vertically long hole 19 to fix the roller bracket 17 to the beam 14a. The roller bracket 17 has a second ear holding roller 18 for preventing ear misalignment.
Is mounted to be rotatable. The pair of second ear holding rollers 18 for preventing ear misalignment respectively press the end faces 4a, 4b of the two ear portions 4, 4 formed in a trough shape. At the time of this pressing, the second ear holding rollers 18, 18 for preventing ear misalignment are adjusted in the left-right x direction and the up-down y direction in the range of the opening of the horizontally long hole 16 and the vertically long hole 19.

すれば、始めから耳ズレは発生しない。Next, the operation of the present embodiment will be described. If an ear misalignment occurs in the traveling cylindrical belt conveyor A, the belt conveyor is stopped once and the vertical position of the second ear pressing roller 18 for preventing the ear misalignment in the vertical y direction. Adjust and restart operation. As a result, the end face 4a or 4b of the ear portion travels at an appropriate vertical position by the pressing force of the second ear pressing roller 18 for preventing ear misalignment, so that the end face 4a or 4b is formed in a cylindrical shape without any ear misalignment. Of course, if the second ear holding roller 18 for preventing ear misalignment is set at an appropriate position in the vertical and y directions by predicting the radius of curvature of the lateral curve before the start of operation, ear misalignment does not occur from the beginning.

耳ズレも防止することができる。Although the present embodiment has described the prevention of ear misalignment that occurs when the flat belt 1 is laterally curved immediately after the flat belt 1 is formed into a cylindrical shape from the flat state, the cylindrical belt conveyer A has a straight line without a lateral curve. Even if they are arranged in a shape, if the flat belt 1 meanders at the tail pulley 11,
Since the trajectories of the end surfaces 4a and 4b of the trough-shaped both ears 4 are asymmetric in plan view with respect to the center line of the belt, ear misalignment occurs even in such a state. Therefore, the present invention can also prevent such ear misalignment.

が、これを円筒形に形成する前に予防するので、簡素な
構成でありながら予想外の便益が得られる。According to the present invention, in the trough shape from when the flat belt is expanded by the tail pulley to when it is formed into a cylindrical shape, that is, when the flat belts are not fitted in a palm-shape manner, the ear gaps that individually press the end faces of the belt ears. Since the second ear pressing roller for prevention is provided, occurrence of ear misalignment can be prevented. In other words, once the ear misalignment occurs in the jointed cylindrical belt conveyor, it takes a great deal of labor and time to resolve it, but since it is prevented before it is formed into a cylindrical shape, it has an unexpectedly simple structure. Benefits are obtained.
殊に、ベルト耳部の両端面を各別に押圧する用第２の
耳押えローラであるから、合掌状態のベルト相互の摩擦
力もなく、その押圧力は僅少ですみ、ひいては耳ズレ防
止用第２の耳押えローラの調整が容易にできる。In particular, since it is the second ear pressing roller for separately pressing both end faces of the belt ears, there is no frictional force between the belts in the closed state, the pressing force is very small, and thus the second ear-preventing roller is used. The adjustment of the ear pressing roller can be easily performed.

Can be prevented.
