Abstract

PURPOSE:To reduce the damage due to abrasion, prevent a drop due to vibration, and improve the plate strength by overlappingly arranging adjacent plates, and forming projections on the plate. CONSTITUTION:In a conveyor endlessly moving multiple plates 10 arranged in the advance direction via a driving device, the plate 10 is formed into a folded shape at the front section 10a of one metal plate so that the plates 10 can be overlapped with each other, and inclined bent sections 10b are formed at both end sections to prevent a drop. Fitting holes 11 to be fixed to a chain are bored on the inside of the bent sections 10b. An angle projection 12 is formed at the center of the flat section 10c of the plate 10 to increase the strength of the plate 10. There is no sliding portion unlike the conventional hinge structure, and the abrasion of the plate 10 can be reduced. The drop of a conveyed object to the outside of the conveyor due to vibration is prevented by the bent sections 10b.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to conveyors, and more particularly to plates.

[0002]

2. Description of the Related Art Conventionally, as a conveyor for carrying heavy objects while preventing slippage, adjacent metal plates are rotatably connected to each other to form an endless belt.
There is a so-called hinged conveyor. In this conveyor, if the hinge part plays a role of non-slip and is made of metal,
Even heavy objects can be transported.

[0003]

However, the hinge-type conveyor has a problem that the hinge portion is heavily worn and the frequency of plate replacement increases. In addition, it is necessary to increase the thickness of the plate material in order to convey heavy objects, and the use of such a material adversely affects the manufacturing cost. Then, this invention provides the conveyor which eliminates the said inconvenience.

[0004]

According to a first aspect of the present invention, there is provided a conveyor for endlessly moving a plurality of plates arranged in a traveling direction through a drive device, wherein adjacent plates are arranged so as to overlap each other and project from the plates. Part is formed. Further, the conveyor according to claim 2 is one in which bent portions for preventing overflow are provided at both ends of the plate according to claim 1.

[0005]

In the conveyor according to the first aspect of the present invention, by forming the protrusions on the plates on which a plurality of plates are arranged, the section modulus of the plates can be increased and the strength can be increased. That is, even if the thickness of the plate is the same, it is possible to carry a heavy object. According to the second aspect of the present invention, in order to prevent the conveyed product from falling from the end of the plate, a bent portion is provided to prevent the falling.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A conveyor of the present invention will be described with reference to the drawings. 1 is a plan view showing a part of the conveyor 1, FIG. 2 is a front view including a partial cross section, and FIG. 3 is a right side view showing a partial cross section. As shown in FIG. 1, the conveyor 1 has a structure in which a large number of plates 10, which will be described in detail later, are juxtaposed in a state of being overlapped with each other. The plates 10 are attached to a chain 9 that moves via sprockets 7 and circulate. Then, the tension of the chain 9 is adjusted by the tension adjusting mechanism 13 attached to the side portion. The conveyor 1 is framed with a base member 2a (angle member), and the peripheral wall of the frame is covered with a side plate 2,
It is supported by a column 3 having a height adjusting mechanism for the conveyor 1. Further, a drive motor 5 with a built-in speed reducer is fixed via a height adjusting mechanism 4a on a support base 4 fixed on the support column 3, and the rotation of the drive motor 5 is controlled by the sprockets 6, 7. The rotating shaft 20 is rotated through the chain 8 which is wound. On the other hand, the bearings 21 fixed to the side plates 2 and 2,
The rotary shaft 20 is rotatably supported on 21, and sprocket wheels 22, 22 around which the chain 9 is wound are fixed. Also, 11
Is a fall prevention plate and is attached to the side plate 2 in an inclined manner.

Next, referring to FIGS. 4 to 7, the plate 10 will be described.
Will be explained. 4 is a plan view of the plate 10, FIG. 5 is a front view, FIG. 6 is a side view, and FIG. 7 is a sectional view taken along line AA of FIG. The plate 10 is formed by a press machine or the like. The plate 10 is formed by forming a front part 10a of a single metal plate into a "F" shape so that the front parts 10a of the plates can be overlapped with each other. The bent portion 10b is formed to prevent falling. In the present embodiment, the shape of the front portion 10a is a shape having a gap when the plates 10 are stacked on each other, but it may be formed in a shape in which they are in close contact with each other.
A mounting hole 11 for fixing the chain 8 is formed inside the bent portion 10b. Furthermore, the plate 10
A mountain-shaped protrusion 12 is formed at the center of the flat portion 10c to improve the strength of the plate 10. The shape of the projection 12 may be a shape such as a circular shape or an elliptical shape having a large section modulus, in addition to the mountain shape.

FIG. 8 shows the plate 1 at the front and rear ends of the conveyor.
4 shows a rotation state of 0, and is a view taken in the direction of arrows BB in FIG. 3. As shown in FIG. 8, in the chain 9 wound around the sprocket 22 that rotates via the rotation shaft 20, a plurality of adjacent plates 10 are arranged in the traveling direction so that the rear portions of the adjacent plates 10 overlap with each other at the tip portion 10a. , The chain 9 through the holes 11 formed in the plate 10 with bolts and nuts (not shown).
Is stuck to. Therefore, in the flat part, the plates 10 move in a horizontal state in an overlapping state, and in the rotating part, each plate 10 rotates while separating from the adjacent plate 10 as it rotates, and overlaps again after the end of rotation. You can move in the state. The shape and overlapping length of the plate 10 can be arbitrarily determined according to the purpose of use, the radius of rotation of the conveyor, and the like.

In the conveyor 1 having the above-mentioned structure, the endless chain 9 is moved through the sprockets 6, 7, and 22 by the drive motor 5 which is rotated at a reduced speed, and the plate 10 attached to the chain 9 is moved. Let Since the protrusions 12 are formed on the plate 10 to increase the strength, it is possible to transport heavy objects as compared with a plate having the same thickness. or,
Unlike the conventional hinge structure, the mutual plates 10 have no sliding parts, so that the wear of the plates can be reduced, the replacement frequency can be reduced, and the economic efficiency can be improved. Further, since the inclined bent portions 10b are formed at both ends of the plate 10, the conveyed product does not fall outside the conveyor due to vibration. Needless to say, it is possible to form the plates into a shape in which the plates are superposed and adhered to each other depending on the article to be conveyed.

[0010]

The conveyor of the present invention is different from the conventional hinge type, and since bent portions are formed at both ends of the plate and protrusions are formed at the flat portion, damage due to wear can be reduced.
It is possible to prevent dropping due to vibration and further improve the plate strength.
