Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a conveyor belt composed of a metal mesh and a ceramic chain.

<Prior Art> Conventionally, a workpiece has been heat-processed by passing the workpiece through a tunnel kiln maintained at a high temperature, such as a firing furnace or a baking furnace.

The conveyor used in the tunnel kiln is as follows:
A trolley conhair for hanging the workpiece, an endless steel belt, or a mesh held with a metal rope attached to the attachment of a metal chain are used.

When the mesh held is used, it is advantageous because the workpiece placed on the belt and conveyed can be uniformly heated from the vertical direction and the horizontal direction.

<Problems to be Solved by the Invention> However, the metschheld, which is composed of the metal chino and the metal mesh, expands under the influence of heat when passing through the tunnel kiln, and cools outside the tunnel kiln. and shrink. Since expansion and contraction act on the metschheld alternately in this way, repeated stress due to heat acts on the belt, resulting in durability problems when used for a long period of time, and it is difficult to obtain a stable conveyance speed. Have difficulty.

Furthermore, lubrication of metal chenos in high-temperature atmospheres has many technical problems, and if this lubrication cannot be carried out properly, the chenos may wear out prematurely or cause noise. There are problems such as the occurrence of

In addition, if a steel chain is used in a high temperature atmosphere, the chain will oxidize and scale will form on the surface, which will have a negative impact on the workpiece and its strength will deteriorate over time, so it is usually manufactured from stainless steel. He uses a specially designed cheno. Therefore, the cost is high.

Furthermore, the metal check 7 has a large number of component parts and has a complicated structure, resulting in high cost.

An object of the present invention is to provide a conveyor belt that retains the advantages of conventional mensch belts, has less thermal influence, and reduces cost.

<Means for solving the problems> In order to solve the above problems, the conveyor belt of the present invention has the following features:
Consists of a metal net formed in an endless shape for placing objects to be transported, and ceramic chains disposed on both sides of the net in the width direction and having locking means for locking the political platform. It is something that will be done.

According to the above means, a ceramic chain (hereinafter referred to as "cheno-j") having locking means is disposed on both sides of the endless metal net in the width direction, and the rope is connected by the locking means. A mesh-like conveyor belt can be constructed by locking the conveyor belt.

In the above configuration, since the coefficient of thermal expansion of the cheno is extremely small compared to that of metal, when it passes through the tunnel kiln, the expansion due to the temperature inside the kiln is extremely small, and a metal mesh is provided on the cheno. Since the conveyor belt is configured by being locked to the locking means, it becomes possible to transmit the tension acting on the belt through a chain that is less affected by heat.

Therefore, the net is locked to the chain and driven by it, and no tension is applied to it. Further, the expansion of the mesh due to heat can be freely expanded without any restriction. As mentioned above, the tension of the belt does not act on the net, and the expansion due to heat is not regulated, so no thermal stress acts on the net.Therefore, there is no stress on the net other than the stress caused by the workpiece placed on the grid. It just doesn't work. Therefore, the durability of the rope can be improved, and since there is almost no expansion due to the effect of heat on the chain, the conveyance speed of the conveyor heald can be maintained at a substantially constant state.

<Example> An example of a conveyor belt to which the above means is applied will be described below with reference to the drawings.

Figure 1 is a perspective explanatory view of a part of the conveyor belt, Figure 2 (
A) and (B) are explanatory diagrams of the rope, Figure 3 is an explanatory diagram of the development of the chain, and Figures 4 (A) and (11) are explanatory diagrams of the conveyor device using the conveyor belt shown in Figure 1. .

In the figure, the conhair belt 1 is composed of an endless metal w42 and two chinos 3 disposed on both sides of the fi42 in the width direction.

The mesh 2 needs to be made of an appropriate material depending on the object for which the conveyor belt 1 is used, but it is usually possible to use a mesh 2 made of steel or stainless steel. In particular, when used in a high-temperature atmosphere such as a tunnel kiln, it is preferable to use a stainless steel mesh 2.

As shown in FIG. 2 (8), the net 2 may be a so-called diamond-shaped net, a shell-shaped net, or a round net, which is constructed by combining steel wires 2a bent in a J-shape. I can do it. It is necessary that the mesh 2 has gaps 2b formed in the thickness direction as shown in FIG. 2(B).

As shown in FIG. 3, the chino 3 has a link member 4. Link plate 5. It is composed of a pin 6 and a shaft rod 7.

That is, the link member 4 is constructed by arranging two side plate members 4a in parallel with a predetermined distance therebetween, and integrally joining these side plate members 4a at a joint portion 4b. Further, a hole 4C for inserting a pin 6 through the side plate member 4a is provided at a predetermined position of the side plate member 4a constituting the link member 4.
is formed. In addition, at the lower center of the side plate member 4a,
A hole 4d into which the shaft rod 7 is inserted is formed.

The link member 4 is made of oxide ceramic raw materials such as alumina and mullite, which are known as heat-resistant and high-strength materials, and ceramic raw materials, such as partially stabilized zirconia (PSZ), which is known as a high-toughness material. It is formed by press molding and firing. This link member 4 can be obtained by integrally molding the shape shown in the figure, but it can also be formed by bonding symmetrically molded members using an adhesive.

The link plate 5 is formed to have a thickness that allows it to fit between the side plate members 4a of the link member 4.

Further, a hole 5a into which a pin 6 is inserted is formed at a predetermined position of the link plate 5. Like the link member 4, the link plate 5 is formed by press-molding a ceramic raw material such as alumina, mullite, or PSZ, and then firing it.

The pin 6 is formed into a cylindrical shape with a predetermined diameter and length. This pin 6, like the link member 4° link plate 5, is formed by press-molding a ceramic raw material such as alumina, mullite, or PSZ, and then firing it.

The shaft rod 7 is! 42, and is formed into a cylindrical shape with a predetermined diameter and length. Then, the link member 4 and the link plate 5 described above. Alumina like pin 6.

It is formed by press-molding a ceramic raw material such as mullite or PSZ and firing it.

The link plate 5 is fitted between the side plate members 43 of the link member 4 formed as described above, and the holes 4c are formed.

By fitting the pin 6 to 5a, the link plate 5 is rotatably connected to the link member 4, and then the other link member 4 is rotatably connected to the link plate 5. In this way, the chino 3 can be constructed by alternately connecting a large number of link members 4 and a large number of link plates 5 with the pins 6. And the hole 4 of the side plate member 4a
By bonding the gap between C and the pin 6 using an inorganic adhesive, it is possible to prevent the pin 6 from falling off from the link member 4, and to connect the link plate 5 to the link member 4 in a rotatable manner. You can.

Also, by fitting the end of the shaft 7 into the hole 4d formed in the side plate member 4a constituting the link member 4, and fixing the shaft 7 to the side plate member 4a using an inorganic adhesive, the net 2 A locking means for locking can be formed to protrude. It is not necessarily necessary to provide the shaft rod 7 for each link member 4, but it is necessary to provide the shaft rod 7 for each link member 4, depending on the shape of the workpiece placed on the net 2.

It can be set as appropriate depending on conditions such as weight.

When constructing the conveyor belt 1 with the mesh 2 and the mesh 3 constructed as described above, the mesh 3 is arranged so that the shaft rods 7 fixed to the mesh 3 face each other, and the mesh 2 is The shaft rod 7 is inserted into the gap 2b formed in the thickness direction.
Insert. When all the shaft rods 7 are inserted into the gaps 2b of the net 2, the conveyor bell l-1 shown in FIG. 1 is completed.

In this way, the conveyor belt 1 can be constructed extremely easily.

In the above-mentioned hair belt 1, the net 2 is simply locked to the shaft 7 fixed to the cinch 3.

Therefore, the tension that acts on the conveyor belt 1 when it runs is transmitted to the chain 3, and no tension for running the conveyor belt 1 acts on 1i12. Therefore, only the weight of the workpiece placed on the platform 2 acts on the net 2. In this way, the conveyor belt 1 of this embodiment is constructed so that the tension for running the conveyor belt 1 can be supported by the chain 3, and the weight of the workpiece being conveyed can be supported by the net 2. There is. Therefore, it is possible to use a net 2 that is weaker in strength than the net used in conventional mesh con hair.

Furthermore, when heating and cooling are repeatedly applied to the conhair belt 1, since the chenette 3 is made of ceramics, it is hardly affected by heat. On the other hand, net 2
Since it is made of metal, it repeatedly expands and contracts under the influence of heat, but since the political cord 2 is not fixed to the chain 3, it repeats free expansion and contraction. Therefore, stress due to thermal effects does not act on the net 2, and therefore sufficient durability can be obtained.

Next, the conveyor belt 1 of this embodiment configured as described above will be described.
An example of a conveyor device configured using the following will be described.

FIG. 4(A) is a plan view of the conveyor device A, and FIG.
B) is its side view.

In the figure, a conveyor belt 1 is wound around a blade pulley 8, a tail pulley 9, and a return roller 10.

Power from a drive device 11 consisting of a motor reduction gear and a transmission is transmitted to the herad pulley 8 via a transmission means 12 such as a chino. Therefore, when the drive device 11 is operated, the conhair belt 1 is configured to be transported in the direction of the arrow a.

Said helad pulley8. Tail pulley9. The return roller lO and the like are attached to predetermined positions on the frame 13. In particular, the tail pulley 9 is attached to the frame 13 via a tension applying means such as a take-up unit (not shown) so as to apply appropriate tension to the chain 3 constituting the conveyor bell 1.

A plate 14 for guiding the conveyor belt 1, particularly the chino 3, is provided on the upper surface of the frame 13. Furthermore, a conveyor belt 1 is placed at a predetermined position on the plate 14.
Two pairs of guide rollers 15 are provided, which are placed on both sides of the guide rollers 15 .

In the conveyor belt A configured as described above, an appropriate tension is applied to the conveyor belt 1 by the tail pulley 9. The head pulley 8 and the chino 3 come into frictional contact due to the tension, and the power of the head pulley 8 driven by the drive device 11 is transmitted to the chino 3 by the contact friction at this time.

FIG. 5 is an explanatory diagram of a case where a chino is constructed by a large number of link plates formed in an oval shape.

In the drawings, the same parts and parts having the same functions as those in the previous embodiment are designated by the same reference numerals, and the explanation thereof will be omitted.

A large number of link plates have an oval shape with a predetermined thickness and length. A hole 16a for inserting the pin 6 is formed at a predetermined position in the front and rear, and a hole 16b for inserting the shaft rod 7 is formed approximately at the lower center of the hole 16a.
is formed.

The link plate is made of alumina, mullite or PSZ.
It is formed by press-molding ceramic raw materials such as and firing it.

To construct a chino using the link plates, first, arrange the two link plates 16c and 16d facing each other, fit the other link plate 16e into this gap, and fit the pin 6 into the 7L 16a. . Then, by bonding the gap between the hole 16a of the link plate h16c16d disposed on the outside and the pin 6 with adhesive, the link plates 16c and 16d are fixed by the pin 6, and the plate 16c.

16d, the link play H6e is rotatably connected. By repeating this operation, link plate 1
A cheno of a predetermined length can be obtained by sequentially connecting 60 to 16e. Next, the shaft rod 7 serving as a locking means is fitted into the holes 16b formed in the link play holes 6c and 16d and bonded, thereby making it possible to construct a chino equipped with a locking means. By attaching the rope 2 to the shaft 7 through the gap 2b, a conveyor belt can be constructed.

When the conveyor belt configured as described above is attached to the conveyor belt 1 described in the previous embodiment, it generates power due to the contact friction between the head boo U8 and the conveyor belt. communicated.

In addition, although the cheno was constructed with a large number of link plates 16cm 16e, by forming the link plate 16e thicker than the other link play holes 6c and 16d,
It is also possible to form the link plates 16c, 16d, 16e and the pin 6 so that their strengths are equal.

In each of the embodiments described above, the chain that constitutes the conveyor belt is configured so that power is transmitted through contact friction with the head pulley 8.

For this reason, if the weight of the workpiece conveyed by the conveyor belt becomes large, there is a possibility that slippage may occur between the chino and the head pulley 8.

In order to prevent the occurrence of the slip, the chain can be formed as shown in FIG. 6(^) or FIG. 7(A).

In FIG. 6(A), a groove 17 is formed in the lower center of the link member described in the first embodiment.

The groove 17 is a groove that meshes with teeth 18a of a sprocket 18 configured as shown in FIG. A chino 20 is constructed by connecting a large number of link members 19 and a large number of link plates 5 with pins 6.

When the conveyor heald constructed using the chino 20 as described above is used in the conveyor apparatus A shown in FIG. 4, a sprocket 8 may be provided in place of the head pulley 8 and tail pulley 9 in the figure.

Moreover, FIG. 7(A) shows a link member described in the first embodiment in which a pin shaft 21 is provided at the lower center of the link member.

The pin shaft 21 meshes with a groove 22a of a groove wheel 22 configured as shown in FIG.
3 is integrally formed. In this case, the pin shaft 21 can be used in common with the shaft rod 7 attached to the link member 23. A chino 24 is constructed by connecting a large number of link members 23 and link plates 5 with pins 6.

When a conveyor belt constructed using the above-mentioned chino 24 is used in the conveyor apparatus A shown in FIG. 4, a groove wheel 22 may be provided in place of the head boob U8 and tail pulley 9 in the figure.

<Effects of the Invention> As explained in detail above, the conveyor belt of the present invention is constructed by locking an endless metal net to ceramic chains arranged on both sides of the political platform. Therefore, the power for running the conveyor belt can be transmitted by the chain, and the weight of the workpieces placed on the conveyor belt can be supported by the net. Therefore, no power for running the conveyor belt acts on the mesh, and therefore the strength of the rope can be reduced compared to conventional mesh belts.

In addition, since the net is locked to the ceramic chain via a locking means, the expansion and contraction that occurs in the grid due to the thermal effects in tunnel kilns etc. is not restricted by the chain, and it can be freely deformed. It becomes possible to do so. Therefore, stress due to expansion and contraction is not generated in the net, so
The durability of the cough rope can be improved.

Furthermore, ceramic chenos have an extremely small coefficient of thermal expansion compared to metal chenos. Therefore, if the conveyor belt of the present invention is used in a tunnel kiln such as a firing kiln, the cough heald will be affected by the heat inside the tunnel kiln. Therefore, even when the workpiece is placed and passed through the tunnel kiln, a stable conveyance speed can be obtained.

Furthermore, compared to conventional metal chenos, ceramic chenos have fewer parts, have a simpler structure, and are easier to assemble, thereby reducing component costs and assembly costs.

In addition, since ceramic chenos have high wear resistance, they hardly wear out even when used without lubrication in high-temperature atmospheres.Therefore, when using the conveyor belt of the present invention, there is almost no maintenance required. This method has features such as being able to obtain a free conveyor device.
