Abstract

PURPOSE:To make it possible to run in a curved manner with one belt by holding both side ends of a conveyer belt with belt lug nippers freely adjustable in position, for supporting the side portions and bottom portion with vertical carrier rollers and bottom rollers to make intervals and so on of these supporting devices variable in accordance with running condition. CONSTITUTION:The titled conveyer carries goods at high speed and in good stability on flat portions through the adjustment of the intervals of belt lug nippers 10 and vertical rollers 14, for enlarging an interval of side walls of a belt to disperse cargo load. Still more on straight portions, rollers are ar ranged in enlarged pitch. And on running portion in curve, together with adjusting the intervals of the belt nippers 10 and the vertical rollers 14 in propor tion to curvature and gradient, the positions of vertical rollers 14 is adjusted downward if necessary. According to this constitution, the conveyer can carry goods at a high speed and in good stability with no need of transshipment by running one long belt upward, downward, rightward and leftward in a curved manner.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a high-speed vehicle in which both sides of the belt are vertically supported to maintain their shape, and the interval between both side walls of the belt is adjusted according to the running conditions of the conveyor to enable tilting and curving movement in the left and right directions. This relates to a U-shaped conveyor with improved stability.

(Prior Art) A conventional U-shaped conveyor has been proposed for a long time and is well known, but the conventional conveyor is simply a flat belt that is supported from below and from the sides by carrier rollers and has a curved cross section. Therefore, it was impossible to turn left and right, that is, in the horizontal direction.

Also, due to its structure, it was not suitable for high-speed transportation.

That is, in a conventional U-shaped conveyor, when the transport speed is increased, the cargo tends to shift to one side, and this causes the belt to meander and become unstable.

Furthermore, when the belt runs in a horizontal direction, the belt rides on the inner carrier roller, making it impossible to run in a curve.

(Purpose) The present invention eliminates the need for loading and unloading work by running a single long belt in a curved manner vertically and horizontally, and also eliminates load shifting even when the belt is driven at high speed. The purpose is to provide a mold conveyor.

(Structure) The belt of the present invention is constructed with an ear belt, and a guide roller that supports the belt ear, a vertical carrier roller and a bottom roller that contact both side walls of the belt are arranged so as to be adjustable in position. The conveyor belt is formed into a U-shape and runs, and the distance between both side walls of the belt can be changed depending on the running conditions of the conveyor belt.

The device of the present invention includes an ear conveyor belt in which enlarged portions are formed symmetrically on both side edges of the belt, an upper and lower two-stage frame that constitutes an outbound path and a return path of this belt, and a vertically disposed structure that is installed vertically on the upper and lower surfaces of each of the frames. a pair of belt selvage clamping devices each having a pair of belt selvage guide rollers and fixed to the frame so as to be adjustable in position; and an outer surface of vertical walls on both sides of the belt attached to inner surfaces on both sides of each frame and connected to the belt selvage. a pair of vertical carrier rollers that are in contact with the frame and whose vertical position and mutual spacing can be varied; and at least one bottom roller provided at the bottom of each frame; The belt edge clamping device and the belt support device are disposed with varying pitches and intervals between them relative to the frame depending on conditions.

(Description of Example Device).

In Fig. 4, (1) is an ear belt, (2) is an enlarged ear formed along both side edges of the belt, (3) is a vertical wall,
(4) is a curved portion. Reference numeral (5) is a conveyor frame mainly constructed by connecting pipes, and is composed of an upper frame (6) constituting an outgoing path and a lower frame (7) constituting a returning path.

Since the configurations of the upper frame and the lower frame are almost the same, the upper frame will be described below.

The upper frame (6) is composed of an upper frame (6A), left and right side frames (6B), and a bottom frame (6), and forms a belt passage (8). (9) is the bottom roller of the belt, which is similar to that used in conventional U-shaped conveyors. (10) is a belt lug holding device attached to the lower surface of the upper frame (6A), which includes two pivots (13) and a pair of guide rollers (11) each holding the belt lug (2). ) and an auxiliary roller (12) are pivotally connected to freely rotate. In addition, the roller (11
) and (12) rotate freely at different circumferential speeds.

The belt edge clamping device (10) is attached to the frame so that its position can be adjusted in the width direction.

(14) is a vertical carrier roller provided on the inner surface of the frame side part (6B).

The vertical roller (14) is rotatably pivoted to a U-shaped roller holding frame (15) (16), and (17) is attached to the end plate (19) of the support frame (18) to connect the roller holding frame (15).
bolt holes (20〉) for adjusting the position of the support frame (18〉). Identification (height position changeable)
21) To be done.

The vertical roller (14) is fixed (21) with its position adjusted in the middle direction and the vertical direction with respect to the conveyor running path (8), and forms a belt support device (22) together with the bottom roller (9).

In the present invention, the conveyor frame is arranged to curve in both the vertical and horizontal directions as shown in FIG.

In the conveyor of the present invention, as shown in FIG. 4, in the straight portion of the conveyor, the distance between the belt side walls is increased, and the distance (pitch) between the rollers in the belt running direction is increased.

In addition, in the turning section, a seventh
As shown in the figure, the belt side wall interval is narrowly shifted and the roller arrangement pitch is small.

(Effect) The conveyor of the present invention has a belt edge clamping device (
Since the interval between the belt side walls is increased by adjusting the interval between 10) and the interval between the vertical rollers (14), the cargo load is dispersed and the belt is stable even during high-speed transportation.

Furthermore, since the roller arrangement pitch can be increased in the straight section, the construction cost is reduced and it is economical.

In areas with large curvature, the belt is transported by narrowing the distance between the vertical side walls as shown in FIG. 7, and the belt edge clamping device (10
) and the vertical rollers (14), and correct the position of the vertical rollers downward as necessary to suppress meandering or supplementary motion of the belt, thereby realizing high-speed, stable transportation.

Although the loading capacity of transported items decreases by narrowing the interval between the side walls of the belt, in the conveyor of the present invention, the traveling speed is not restricted by the curved section unlike the conventional conveyor, so high-speed traveling is possible, and the overall transportation volume is reduced. The amount increases rather than decreases, and transportation costs are reduced.

Furthermore, in the conveyor of the present invention, it is of course possible to carry out reciprocating transportation using the return conveyor of the lower frame.
