Description

Chain conveyor

The present invention relates to a chain conveyor, and in particular, it is possible to install in a low phase shape having a low installation height, the volume of the transport block is small, and even if the length of the chain is long because the transport distance is far, there is no deflection phenomenon, The present invention relates to a chain conveyor capable of transporting an unlimited amount of weight from light items to articles by moving on a rotating roller.

In general, the chain conveyor is used more in the transfer of goods than the belt conveyor.

Such use of the chain conveyor is typically used to transfer heavy parts in various automated facilities and cargo transfers and automobile assembly lines.

Conventionally, a chain conveyor is known in which a chain is wound on a pair of chain wheels on an endless and a wooden board is fixed to a bracket of the chain so that the chain can be rotated on a track by a geared motor. When the chain moves the upper rail, the chain is moved in direct contact with the upper rail and the wooden board is moved in contact with the guide rail of the lower rail, which causes a lot of movement resistance, which causes chain breakage due to excessive load and friction of the wooden board. There was a problem that the service life of the motor can not be maintained for a long time due to frequent failures due to fast wear and short use of the motor.

As a known technique for solving the above problems, Korean Patent Registration No. 20-0396958 has been proposed under the name of the chain moving device of the chain conveyor.

As described above, the chain moving device of the conventional chain conveyor is to wind the chain around the chain wheel arranged on both sides of the frame and to fix the square stainless bar to the bracket so that the chain can be rotated along the upper and lower rails by the geared motor. In the pins connecting the chain link plate is installed so that the movement of the chain is made smoothly by the rotation of the roller.

As described above, the chain moving device of the conventional chain conveyor has an effect of preventing the deflection by installing a roller on the chain to move along the rail.

However, in the chain moving device of the conventional chain conveyor, the bracket on which the article to be transported is connected to the chain, and the weight of the article is transferred to the chain through the bracket, so that the load is transmitted to the chain and the load is applied to the sprocket or the motor. There was a problem.

In addition, the chain transfer device of the conventional chain conveyor is difficult to manage and create a pleasant working environment by abrasion of the pins that secure the roller when the roller is continuously moving along the upper and lower rails, and wear and noise and vibration between the roller and the rail. There was a problem that could not be done.

Therefore, the present invention has been made in view of the problems of the prior art as described above, by continuously installing a transport block combined with rollers and sprockets in one or more numbers in the transport direction along the transport direction to increase the transport distance. It is an object of the present invention to provide a chain conveyor that does not cause sagging and elongation problems in the chain even if the length increases.

Another object of the present invention is to prevent the load from being applied directly to the chain and the sprocket by transferring the article by the rotational force of the roller rotating by friction with the idle sprocket connected to the chain.

In addition, another object of the present invention is to adjust the driving force according to the difference in the weight of the article to be transported by adjusting the friction force of the rotating roller and the idle sprocket.

In addition, another object of the present invention is to be transported by placing the article to be transported on the rotary roller is to transport the article and to adhere the rubber on the surface of the roller so that the impact and vibration does not occur during contact with the article.

In order to achieve the above object, the present invention provides a drive shaft in which a pair of drive sprockets are coupled to both ends of a pair of frames installed side by side to move various articles or parts in one direction. It is installed to rotate, the rotation roller is coupled to the rotation roller is inserted into the inside of the pair of brackets, the transport block combined with the idle sprocket to fit the other side of the rotation roller along the length of the upper frame The chain conveyor is installed in plurality, and the chain connected to the driving sprocket is connected to the idle sprocket of the transfer block, and is configured to transfer the goods loaded on the upper part of the rotating roller which receives the rotational force of the idle sprocket. In the rotary roller, one side portion of the through hole through which the shaft penetrates to the center of the roller end is extended to form an expansion space. A cylindrical fastening end is formed, and the end of the fastening end is divided into two parts so as to face the fitting end, and one side of the idle sprocket is inserted into the expansion end of the fastening end so as to be rotated. And a pressure plate coupled to the other side of the idle sprocket and spirally fastened to an end of the shaft passing through the fastening end, and formed with a fitting hole in which the fitting end is fitted. do.

As described above, the present invention continuously installs a transport block in which a number of rollers and sprockets are coupled to the transport port along the transport direction so that the chain is sag even if the length of the chain increases due to an increase in the transport distance. It is easy to manage by replacing only the corresponding transport port when replacing due to failure.

In addition, the goods are transferred by the rotational force of the roller rotating by friction with the idle sprocket connected to the chain, so that no direct load is applied to the chain and the sprocket, and the load is not transmitted to the drive motor, and the chain and the sprocket are worn. And there is an effect that deformation does not occur.

In other words, by supporting the lower surface of the chain 40 in contact with the chain 40 is configured to not be stretched downward.

Hereinafter, the operation and operation of the present invention will be described.

As shown in Figure 1a to 10, the conveyor 100 is configured to transport the goods in one direction, Idle sphering 34b is inserted into the fastening end 33d of the rotary roller 33, and an idle spherical body having a pair of bushings 34a which partially covers the inner diameter and both side ends of the idle sprocket 34 is coupled. When the kit 34 is fitted to engage and one side of the bushing 34a presses the close contact bushing 34b, the close contact 34b is installed to rotate while being in contact with the extension end 33e.

Thereafter, the shaft end 32b of the shaft 32 penetrates the bracket 31 and the locking head end 32a is coupled to the shaft end 32b with the spring 32c positioned so as to be positioned inside the expansion space 33c. After insertion, it is inserted into the extended end (33e) of the rotary roller (33).

One end of the spring 32c is supported by the locking head end 32a and the other end is supported by the step 33c '.

At this time, the pair of brackets 31 are coupled to each other, so that the circumferential surface of the rotary roller 33 is partially exposed through the exposure hole 31a, and the rotary roller 33 and the idle sprocket 34 are not separated. Combine while avoiding.

Next, the end of the shaft end 32b passing through the end 33d of the rotary roller 33 is helically fastened to the pressing plate 35, the end 33d to the fitting hole 35a of the pressing plate 35. Insert the fitting end (35d ') of the) completes the assembly of a plurality of transport block 30 is coupled so that the rotation plate 33 rotates together when the rotary roller 33 rotates.

Thereafter, the chain 40 is connected to the idle sprocket 34 of the driving sprocket 21 and the transfer block 30 in a caterpillar form to complete the assembly of the conveyor 100.

Thus, the transport block 30 is completed assembly is fixed to the upper portion of the frame 10 is not installed sag on the chain 40 separately, so there is no need to adjust the tension of the chain 40, idle spr When replacing the kit 34, by replacing only the transport block 30 in which the idle sprocket 34 is located, the replacement cost is reduced and easy management.

In addition, in order to replace the transfer block 30, simply lift the transfer block 30 in the state of releasing the connection with the idle sprocket 34 by lifting the chain 40 positioned at the top to move upward. By dismantling the fastening with the frame 10 is characterized by a simple replacement.

On the other hand, the chain 40 is coupled to the lower portion of the idle sprocket 34 by the support 12 is coupled to the upper portion of the frame 10 where the lower apex of each idle sprocket 34 is located By contacting and supporting the moving chain 40, even if the length of the chain 40 is long, there is a feature that sagging down does not occur.

As such, when the driving motor 20 is driven to use the completed conveyor 100, the driving force is transmitted to the reducer sprocket 22b coupled to the reducer shaft 22a through the reducer 22.

Thus, the transmitted driving force is transmitted to the power transmission sprocket 21b connected to the reduction gear sprocket 22b and the power transmission chain 22c.

Thereafter, the drive shaft 21a to which the drive sprocket 21 is coupled rotates together with the rotation of the power transmission sprocket 21b.

In addition, in order to drive the conveyor 100, when the driving motor 20 is driven, the reduction gear sprocket 22b of the reduction gear 22 rotates to move the power chain 40-> to the driving shaft 21a. Combined power transmission sprocket 21b rotates with drive shaft 21a-> rotation of chain 40-> idle sprocket 34-> bushing 34a and tight bushing of transfer block 30 34b, the pressure plate 35-> the rotation roller 33, the shaft 32, the spring 32c is transmitted in the order to rotate all at the same time.

At this time, when the idle sprocket 34 is rotated by the movement of the chain 40, the inner circumferential surface of the idle sprocket 34 is fitted with the outer circumferential surface of the fastening end 33d of the rotary roller 33 and idle One side of the sprocket 34 is rotated by the rotary roller 33 due to the frictional force of the contact with the expansion end (33e).

Then, the article to be conveyed is placed on the upper portion of the rotary roller 33 and is conveyed by the rotational force of the rotary roller 33.

In this case, when the article to be conveyed is an article (for example, 500 kg), a sliding phenomenon occurs on a surface where the rotary roller 33 and the idle sprocket 34 come into contact with each other due to the weight, and thus the rotational force of the idle sprocket 34 is caused. It may not be smoothly transmitted to the rotary roller 33.

In this case, when the tool is inserted into the tool hole 32b 'formed at the shaft end 32b of the shaft 32 and rotated, the pressing plate 35 is tightened to press the bushing 34a. It moves while pressing the spring 32c.

Thereafter, the shaft 32 is pushed by the restoring elastic force of the pressurized spring 32c to pull the pressure plate 35 toward the rotation roller 33.

The pressure plate 35 presses the idle sprocket 34 so that one side of the extended end 33e of the rotary roller 33 and the side surface of the idle sprocket 34 press the contact surface, thereby causing a sliding phenomenon. Without the rotational force of the idle sprocket 34 is transmitted to the rotary roller 33 has a feature that enables the smooth transfer of the article.

On the other hand, if the chain 40 is unable to move due to excessive loading of the goods, the idle sprocket 34 and the power transmission chain 21b cannot rotate and move, and the driving force of the driving motor 20 continues to the reducer 22. When transmitted to, the reducer 22 and the drive motor 20 is rotated relative to the reducer shaft (22a).

As a result, when the driving motor 20 is rotated, when contacted with the overload switch 23 for supplying power, the supply power to the driving motor 20 is cut off to prevent the overload of the driving motor 20, thereby preventing the device from being damaged and driven. There is a feature that can protect the motor 20.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein. Various changes and modifications may be made by those skilled in the art.
