, And the endless omni grit belt 4 is caused to travel in a predetermined direction by a frictional force between each belt pressing piece 9 and the inner end of the end portion of the endless omni grit belt 4. In the prior art constructed as described above, the belt pressing piece 9 is pressed against the inner end of the corner portion of the endless omni grit belt 4 and pressed outward. Since the endless drive chain 8 is driven by the frictional force while running, not only a large driving force is always required, but also a large tension is applied to the corner portion of the endless omni grit belt 4. It works. For this reason, a large amount of power is required, resulting in not only high costs but also drawbacks such as the endless omni grit belt 4 being easily stretched or damaged. [0006] The present invention solves the conventional problems at once,
It is an object of the present invention to provide an edge drive conveyor that can always and quickly run the running operation without causing the endless belt to be stretched or damaged with a small power cost. That is, according to the first aspect of the present invention, a pair of timing belts 22 on both sides are provided below a straight running surface of an endless belt 4 constituting an edge drive conveyor 21.
There is disposed to be freely driven synchronously Rutotomoni, of the endless belt 4
The inner circumference of the corner portion is located through a take-up 32.
A required number of guide rollers 35 are not provided at a predetermined pitch.
The edge is characterized in that the timing belt 22 is driven in a predetermined direction while being guided by the guide roller 35 , so that the endless belt 4 can run with its frictional force. The gist is a drive conveyor . [0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS be described with reference to an embodiment shown in the form in the figures of the present invention. FIGS. 1 to 6 show an embodiment of the present invention. In FIG. 1 to FIG. 6, reference numeral 22 denotes a lower portion of a straight running surface for contacting the inner and outer lower surfaces of an endless omni grit belt 4 constituting an edge drive conveyor 21. A pair of two timing belts are disposed inside and outside so as to be synchronously driven, and each of the timing belts 22 includes a driving timing pulley 23 and a driven timing pulley 24 disposed at a predetermined interval. And the driving timing pulley 23 and the driven timing pulley 24 facing inward and outward are formed coaxially. Reference numeral 25 denotes a drive timing group facing the inside and outside.
A drive shaft connected to one shaft 26 of the ri 23 via a winding transmission mechanism 27 such as a timing chain; 28, a driven shaft connected to the other shaft 29 via a winding transmission mechanism 30; Reference numeral 31 denotes a wrapping transmission mechanism such as a timing chain for connecting the driven shaft 28 and the drive shaft 25. The drive shaft 25 is rotatable in a predetermined direction by a required motor (not shown) . Reference numeral 32 denotes a core of the endless omni grit belt 4.
A take-up disposed at the corner portion, a frame-shaped movable frame 33 constituting the take-up 32, and a substantially semicircular inner guide rail 34 attached to the movable frame 33. A required number of guide rollers are mounted on the inner guide rail 34 via a required mounting member 36 so as to partially protrude into the traveling path of the endless omni grit belt 4.
Reference numerals 37 denote a pair of fluid pressure cylinders on both sides for moving the movable frame 33 outward. Other parts are the same as those of the conventional example, and the same reference numerals indicate the same parts . [0010] The following describes the operation of the embodiment constructed as described above. First, the tension of the endless omni grit belt 4 is properly adjusted by operating the fluid pressure cylinder 37 and moving the movable frame 33 outward. At this time, endless omni grit belt 4
Should be set smaller than in the conventional example. Thereafter, the drive shaft 25 is driven in a predetermined direction by the activation of the motor (not shown), and the winding transmission mechanism 27.
The inner and outer timing belts 22 are operated synchronously in the same direction via 30 and 31. Then, a frictional force acts between the timing belt 22 and the lower surface of the endless omni grit belt 4 by the synchronous running operation, and the endless omni grit belt 4 is caused to run in a predetermined direction by the frictional force. In this case, the guide roller 35 guides the vehicle to bend and perform a traveling operation to convey a required object. At this time, as described above, the endless omni-grit belt 4 uses the frictional force generated by synchronously operating the inner and outer timing belts 22 in the predetermined direction to perform the running operation. There is no need to apply a large tension to the endless omni grit belt 4 itself, and the running operation can be always performed reliably with a small power without causing the endless omni grit belt 4 to elongate or be damaged. Also at the corners, the tension at the inner end of the endless omni grit belt 4 is adjusted by the take-up 33.
Since the vehicle is operated to bend while being guided by the guide roller 35 while being pressed, it is possible to always perform a smooth running with small friction . In the above embodiment, the two timing belts 22 on both sides are provided two each. However, the present invention is not limited to this, and the number may be increased or decreased. . Although the endless omni-grid belt 4 is shown as an endless belt constituting the edge drive conveyor 21, the present invention is not limited to this, and an endless omni-flex belt or an endless filler mesh belt may be adopted and used. Things . According to the first aspect of the present invention, a pair of timing belts 22 on both sides are synchronously driven below the straight running surface of the endless belt 4 constituting the edge drive conveyor 21 as described above. is set Rutotomoni, U the endless belt 4
-Necessary for the inner circumference of the corner through take-up 32
The number of guide rollers 35 is not provided at every predetermined pitch.
Since the timing belt 22 is driven in a predetermined direction while being guided by the guide roller 35, the endless belt 4 is driven to run by the frictional force. There is no need to apply a large tension to the endless belt 4 itself, and the running operation can be performed by applying a small tension at all times. As a result, the endless belt 4 may be stretched or damaged with a small power. Not only can the running operation be carried out without fail, but also the tension of the inner end of the endless belt 4 can be adjusted by the take-up 32.
It is possible to bend and run while guiding through the guide roller 35 while squeezing.
