Description

[Technical field]

[0001] The present invention relates to a conveyor chain adhesion prevention device for preventing adhesion that would impede the movement of a conveyor chain in a conveyor device such as a flight conveyor that transports materials such as incineration ash mixed with powder, moist ash, etc.

[0002] In particular, the present invention relates to a conveyor chain adhesion prevention device that allows a cam to slide on an axis so that excessive torque (load) is not applied to the axis that rotates the arm to which the hammer is attached when lifting the hammer in order to prevent the conveyor chain from sticking.

[0003] When transporting incineration ash that contains moisture, a scraper conveyor is used to move the material by sweeping it with a scraper. In this case, the scraper is driven by a conveyor chain attached to the scraper.

[0004] This conveyor chain is composed of pins, bushes, rollers and plates, and sometimes incineration ash or other materials get in between the connecting or sliding parts. When this happens, the moisture in the incineration ash evaporates, causing the ash to solidify, which can cause the connecting or sliding parts to move poorly, and can prevent the rollers from rotating smoothly.

[0005] If the rollers do not rotate, sliding resistance occurs between the rollers and the guide rails, which increases the energy required for operation and can lead to increased electricity consumption.

[0006] In addition, the non-rotating rollers slide on the guide rails, causing wear on the rollers and the guide rails, and putting excessive strain on the conveyor chain, resulting in problems such as shortening the lifespan of the conveyor chain and the rails.

[0007] For this reason, it is desirable to remove the incineration ash and other materials that have become lodged between the pins, rollers, and plates of the conveyor chain. If the ash and other materials are not removed for a long period of time or if maintenance is not performed, the conveyor chain will become stuck, and it is desirable to prevent this from happening. [Background technology]

[0008] Conventionally, when incineration ash and the like is transported by conveyor, most conveyors are casing type, which means that it is not possible to see inside the conveyor. This means that it is not possible to directly see the amount of incineration ash and the like being transported, the transport status, the conveyor drive status, etc., making it difficult to understand the operation of the conveyor.

[0009] For this reason, it is desirable to be able to grasp the condition inside the conveyor by measuring the tension of the conveyor chain, thereby making it possible to visualize the operation inside the conveyor, predicting conveyor chain wear and deformation of the guide rails, and also to plan the timing of part replacement.

[0010] However, measuring the tension of a conveyor chain inside a conveyor requires that the conveyor chain itself is running normally.

[0011] In other words, a conveyor chain operating normally means that there is no combustion ash or the like stuck between the pins, bushes, rollers and plates that make up the conveyor chain, the conveyor chain is not bent or stuck, and the rollers that make up the chain rotate smoothly on the guide rails.

[0012] If ash containing moisture gets in between the plates that make up the conveyor chain and the moisture evaporates and the ash hardens, the plates will have difficulty bending smoothly, and may even become stuck in a bent position, causing poor bending.

[0013] In addition, when the plate is bent and stuck in this manner, the overall length of the left and right conveyor chains changes, and the lengths of the left and right conveyor chains become different. This makes it impossible to accurately measure the tension of the conveyor chains. In addition, since the lengths of the left and right conveyor chains are different, it becomes difficult to adjust the chain tension appropriately by the take-up operation.

[0014] Furthermore, a conveyor chain that is not properly bent may come into contact with a guide rail and break, which may force the conveyor to stop operating.

[0015] For this reason, currently, the problem is that the non-rotating parts of the chain and rollers are struck with a hammer or similar tool about once a month to remove any stuck areas.

[0016] This work is effective in eliminating the sticking of the bends, but it is dangerous because it is done while the conveyor is running. Also, in order to stop the conveyor equipment for a long time periodically, the incinerator must also be stopped, which affects the operation and maintenance of the system, and is not efficient. Also, if the regular work is neglected, the entire conveyor may stop due to the sticking or bends of the chain, and the incinerator may also stop.

[0017] In addition, even when the conveyor chain is in a normal state, it is difficult to measure the tension of the chain. In addition, when the chain is defectively bent, it is even more difficult to measure the tension accurately.

[0018] In addition, when hard, large pieces of incineration ash get stuck between the scraper and the bottom plate of the conveyor, the jam can be cleared by rotating the conveyor forward and backward, but it is difficult to perform this operation automatically. The reason for this is that if the chain is not properly bent, reversing the movement can cause an accident that could damage the conveyor itself.

[0019] Therefore, if it is possible to prevent bending defects from occurring, it would be extremely effective to automate the forward and reverse rotation of the conveyor chain.

[0020] Therefore, the object of the present invention is to provide a conveyor chain adhesion prevention device that periodically applies an impact to the conveyor chain to remove ash and other materials that may become lodged between pins, bushes, rollers, plates, etc. and cause adhesion, and also to prevent any material that has gotten in from becoming stuck. [Prior art documents] [Patent documents]

[0021] [Patent Document 1] JP 2021-141052 Chain Cleaning Mechanism This document discloses a mechanism for cleaning a chain using a rotating brush, but cleaning with a rotating brush makes it difficult to remove ash and other particles that have gotten into the small gaps between the chain pins and rollers, and is unable to deal with cases where adhesion has already occurred between the roller and plate. Summary of the Invention [Problem to be solved by the invention]

[0022] When incineration ash, etc. is transported by conveyor, it is possible to see the amount of transported material, the transport state, the conveyor drive state, etc., and to grasp the operation of the conveyor by measuring the chain tension, thereby visualizing the operation within the conveyor, predicting chain wear, rail deformation, etc., and making it possible to plan the timing of part replacement.

[0023] Therefore, in order for the conveyor chain to drive smoothly, ash and the like that has entered the gaps between the pins, rollers, plates, etc. that make up the conveyor chain and adheres thereto due to impact is removed, and the adhesion of the adhered matter is prevented in advance.

[0024] In addition, by grasping the change in tension applied to the left and right conveyor chains, the slack in the conveyor chain can be grasped, and the tension of the conveyor chain can be appropriately adjusted by easily performing the take-up work of the driven shaft.

[0025] Furthermore, it is possible to reduce wear on the conveyor chain, extend its lifespan, save energy, and reduce wear on guide rails, sprockets, etc., thereby reducing running costs and contributing to decarbonization.

[0026] Conventionally, the time (period) for which the conveyor was operated was determined based on the degree of adhesion of ash and the like to the chain, and workers would strike it with a hammer once or twice a month. However, this eliminates the need to stop the conveyor, inspect the inside of the conveyor, and have workers use a hammer or the like to dissolve stuck chains, thereby providing a conveyor chain adhesion prevention device that is excellent in terms of safety and reduced labor costs.

[0027] The present invention provides a conveyor chain adhesion prevention device that can be used in both forward and reverse rotation of the conveyor, preventing the adhesion of such ash and the like, which causes poor rotation of the rollers and poor bending of the conveyor chain, and enables the conveyor to be driven automatically even if it is clogged. [Means for solving the problem]

[0028] The first invention is a device for preventing adhesion of a conveyor chain, which comprises a shaft holding part, a shaft passing through the shaft holding part, an arm that can slide on the shaft, a hammer attached to the tip of the arm, and a cam that can slide on the shaft and be inserted between the plates of a conveyor chain, and in accordance with the movement of the conveyor chain, the tip of the cam comes into contact with the rollers of the conveyor chain, causing the cam to rotate around the shaft, the cam pushes up the arm, and the hammer attached to the tip of the arm is lifted, and when the tip of the cam is released from contact with the rollers of the conveyor chain, the cam returns to its original position and the hammer strikes the rollers of the conveyor chain.

[0029] As a second invention, a conveyor chain adhesion prevention device is provided in which the side of the cam is brought into contact with the arm, pushing up the arm and lifting a hammer attached to the tip of the arm.

[0030] As a third invention, a hook portion is provided on the side of the cam, and the hook portion pushes up the arm, thereby lifting a hammer attached to the tip of the arm, thereby providing a device for preventing adhesion of a conveyor chain.

[0031] As a fourth invention, a conveyor chain adhesion prevention device is provided in which the hammer attached to the tip of the arm is cylindrical and can rotate around the center of the cylinder.

[0032] As a fifth invention, the hammer attached to the tip of the arm is cylindrical, and the size or width of the cylinder can be adjusted to provide a conveyor chain adhesion prevention device.

[0033] As a sixth invention, a conveyor chain adhesion prevention device is provided in which the arm can be fixed to the upper part so that the hammer does not come into contact with the conveyor chain. Effect of the Invention

[0034] According to the present invention, even if ash or the like gets into the gaps in the conveyor chain, the adhesion prevention device applies an impact to the conveyor chain to shake off the ash or the like, thereby preventing the chain from adhering or becoming permanently stuck.

[0035] In addition, because the arm to which the hammer is attached is always able to slide on the shaft, excessive torque (load) is not applied to the shaft even when the cam comes into contact with the roller of the conveyor chain.

[0036] In addition, since the tip of the cam is always inserted between the rollers of the conveyor chain, it has the effect of removing any deposits that may be present between the plates of the conveyor chain.

[0037] In addition, the hammer attached to the tip of the arm is cylindrical and can rotate around the center of the cylinder, allowing the hammer to move smoothly on the conveyor chain. Even if the conveyor chain rotates in the reverse direction, the hammer will not get stuck in the conveyor chain.

[0038] In addition, the hammer attached to the end of the arm is cylindrical and the size or width of the cylinder can be adjusted, making it possible to make the hammer suited to the adhesion conditions of the conveyor chain.

[0039] In addition, when it is not necessary to operate the adhesion prevention device all the time or when the conveyor rotates in reverse, the arm can be fixed at the top so that the hammer does not hit the conveyor chain. Also, even when the conveyor rotates in reverse due to the automation of the conveyor, the arm supporting the hammer can slide on the shaft, so that the hammer can move up and down smoothly on the conveyor chain.

[0040] This allows the conveyor chain to be driven smoothly, and the presence and amount of transported goods can be accurately measured based on the measurement data of the tension of the conveyor chain, making it possible to achieve "visualization of operation."

[0041] In addition, based on the tension measurement data, the movement of the scraper conveyor can be automatically controlled to operate intermittently or at a slower speed, thereby saving energy.

[0042] Furthermore, wear on conveyor chains, guide rails, and sprockets can be reduced, the number of parts that need to be replaced is reduced, and the longer life of the parts means that the number of parts to be manufactured can be reduced, thereby achieving decarbonization.

[0043] Furthermore, since the present invention allows the conveyor chain to be driven smoothly, the tension on the chain of the scraper conveyor can be measured, recorded, and the tension data analyzed based on the numerical tension value, allowing an accurate understanding of the engagement between the scraper and the bottom plate of the scraper conveyor, providing operational assistance to ensure normal operation and contributing to work style reform.

[0044] Furthermore, since the present invention allows the conveyor chain to be driven smoothly, it is possible to measure the tension on the chain of the scraper conveyor, record the tension, and analyze the tension data based on the tension value, thereby making it possible to grasp changes in the left and right direction of the conveyor, when it is time to replace the chain, and the condition of the chain.

[0045] For example, if there is a tendency for the chain tension on the left side to be high, it can be inferred that the rails of the left conveyor are worn out or damaged, making it possible to speed up inspection and prevent fatal problems before they occur.

[0046] In addition, by preventing poor bending of the conveyor chain, the forward and reverse rotation of the conveyor chain can be automated, making the conveyor operation more efficient. [Brief description of the drawings]

[Figure 11] FIG. 1 is a front view of the conveyor chain adhesion prevention device of the present invention with a thicker hammer BEST MODE FOR CARRYING OUT THEINVENTION

[0048] Example 1 FIG. 1 is a plan view of the anti-adhesion device for a conveyor chain of the present invention, FIG. 2 is a side view of the anti-adhesion device for a conveyor chain of the present invention, and FIG. 3 is a front view of the anti-adhesion device for a conveyor chain of the present invention.

[0049] In addition to scraper conveyors, the present invention can also be used for conveyors driven by two conveyor chains, such as apron conveyors, bucket elevators, and slat conveyors, and is a device for preventing adhesion of conveyor chains. In addition, the present invention can be used as a device for preventing adhesion of conveyor chains not only for top-return type scraper conveyors, but also for other scraper conveyors.

[0050] Furthermore, the present invention is applicable to a flow conveyor using a single conveyor chain.

[0051] In Figures 1 to 3, 1 is a base that is installed on both sides of a double-strand conveyor chain. 2 is a shaft holder that is attached to base 1. Also, shaft holder 2 can be adjusted by changing the mounting position of base 1.

[0052] Reference numeral 3 denotes a shaft, which is provided so as to penetrate the shaft holding portion 2 and is held by the shaft holding portion 2. The shaft 3 is not limited to being fixed to the shaft holding portion 2, and may also be rotatable within the shaft holding portion 2.

[0053] Reference numeral 4 denotes a cam, which is slidably provided on the shaft 3. By allowing the cam 4 to slide on the shaft 3, the torque (load) acting on the cam 4 is not directly applied to the shaft 3.

[0054] It is also effective to attach a bearing to the inside of the cam 4 in order to slide the cam 4 on the shaft 3. It is also effective to use a lubricant such as oil to ensure smooth sliding.

[0055] Reference numeral 5 denotes an arm, which is slidably attached to the shaft 3. The length, shape, strength, etc. of the arm 5 can be adjusted as appropriate. In addition, by allowing the arm 5 to slide on the shaft 3, the load on the arm 5 is not directly applied to the shaft 3.

[0056] The cam 4 and the arm 5 are configured to slide together on the shaft 3, and each can rotate separately about the shaft 3.

[0057] A hammer 6 is attached to the tip of the arm 5. The weight, size, material, etc. of the hammer 6 can be adjusted as appropriate. Also, the attachment position of the hammer 6 at the tip of the arm 5 can be adjusted as appropriate.

[0058] The shape of the hammer 6 is not limited to a cylindrical shape and can be selected as appropriate. In addition, when the hammer 6 is cylindrical, by making the center of the cylinder rotatable around an axis provided at the tip of the arm 5, the hammer can be moved while rotating on the conveyor chain.

[0059] The size, width, etc. of the hammer 6 can be adjusted as appropriate.

[0060] Here, the thickness of the hammer 6 will be described.

[0061] FIG. 8 is an explanatory side view of the conveyor chain anti-adhesion device of the present invention in which the hammer has a thinner thickness, and FIG. 9 is an explanatory front view of the conveyor chain anti-adhesion device of the present invention in which the hammer has a thinner thickness.

[0062] FIG. 10 is an explanatory side view of the present invention's conveyor chain anti-adhesion device with a thicker hammer, and FIG. 11 is an explanatory front view of the present invention's conveyor chain anti-adhesion device with a thicker hammer.

[0063] As shown in Figures 8 and 9, if the thickness of the hammer 6 is made thinner than the gap between the plates 8, the hammer 6 will be inserted between the plates 8, making it possible to push out the incineration ash and other materials stuck between the plates.

[0064] Furthermore, by making the width of the hammer 6 narrower than the gap between the plates of the conveyor chain, it is possible to make it an adhesion prevention device that prevents minor adhesion.

[0065] On the other hand, if the thickness of the hammer 6 is made thicker than the spacing between the plates 8, as shown in Figures 10 and 11, the hammer 6 will not get caught between the plates of the conveyor chain or on the rollers of the conveyor chain.

[0066] This is particularly effective when the conveyor chain is rotated in reverse because it does not get caught between the plates.

[0067] 7 shows the entire conveyor chain.

[0068] Plates 8 constitute the conveyor chain 7 and are made up of an outer plate and an inner plate.

[0069] Reference numeral 9 denotes rollers which constitute the conveyor chain 7 and are fixed by plates and pins.

[0070] Reference numeral 10 denotes a stopper that supports the arm 5 so that it does not drop too far, and prevents the hammer 6 at the tip of the arm 5 from getting caught between the plates of the conveyor chain even if it is narrow, and also prevents the hammer 6 from getting stuck between the rollers 8 of the conveyor chain even if the conveyor chain runs in reverse.

[0071] The operation of the conveyor chain 7, the cam 4 and the arm 5 will now be described.

[0072] When the conveyor chain 7 moves to the right, the roller 9 comes into contact with the tip 11 of the cam 4, causing the cam 4 to rotate counterclockwise around the axis 3, and the side surface 12 of the cam comes into contact with the arm 5, lifting the arm 5 as the cam 4 rotates, thereby lifting the hammer 6 attached to the tip of the arm 5.

[0073] As the conveyor chain 7 continues to move to the right, the tip 11 of the cam 4, which was in contact with the roller 9, is released from the roller 9, and the cam 4 returns to its original position, the arm 5 also descends, and the hammer 6 at the tip of the arm 5 strikes the roller 9, making it possible to remove anything attached to the conveyor chain.

[0074] This operation can be repeated as the conveyor chain moves.

[0075] In particular, by positioning the hammer 6 to strike the roller 8 at a position where there is no guide rail that comes into contact with the bottom plate, the hammer 6 can deliver a stronger impact to the roller 8, resulting in an excellent effect in preventing the conveyor chain from sticking.

[0076] This impact can knock off ash and other debris adhering to the roller 9. If the roller 9 is already stuck or if the chain is not properly bent, the impact can break the adhesion. In addition, the material adhering to the scraper attached to the chain can be knocked off at the same time by the hammer striking the roller.

[0077] In addition, since the arm 5 slides on the shaft 3, the hammer 6 can move smoothly up and down on the conveyor chain 7 even when the conveyor chain 7 is moved in the reverse direction.

[0078] The case where the anti-adhesion device for a conveyor chain according to the present invention is stopped will be described.

[0079] Reference numeral 13 denotes a pin. When the conveyor chain adhesion prevention device is not in use, by fixing the arm 5 to the pin 13, the lifting of the arm 5 caused by the rotation of the cam 4 can be stopped, and the operation of the adhesion prevention device can be stopped.

[0080] If operation of the adhesion prevention device is sufficient for only a few hours a week, this problem can be solved by lifting the hammer 6 manually or automatically. Also, as a means for automatically lifting the hammer 6, it is possible to operate it automatically periodically using a cylinder or the like. Also, by lifting the hammer 6 periodically, wear on the plates 8, rollers 9, and hammer 6 of the conveyor chain can be reduced.

[0081] In this embodiment, an example is shown in which the arm 5 is fixed to the pin 13. The locking method is not limited to the pin, and a hooking method is also possible.

[0082] In addition, the anti-adhesion device for conveyor chains of the present invention does not need to be operated all the time, but can be set to operate when there is a lot of adhesion to the conveyor chain. For example, when not in use, the arm 5 can be fixed to the pin 13 to prevent the anti-adhesion device from operating, which prevents unnecessary wear of the cam and hammer and noise.

[0083] The present invention provides a device for preventing adhesion of such ash and the like to a conveyor chain, which prevents the rollers from rotating poorly and the conveyor chain from bending poorly due to the adhesion.

[0084] Example 2 In the second embodiment, the mechanism by which the cam 4 pushes up the arm 5 is used as a hook portion.

[0085] 4 to 6, reference numeral 14 denotes a hook portion which is provided on the cam 4. As shown in FIG.

[0086] When the hook portion 14 comes into contact with the arm 5, the arm 5 is pushed up, and the hammer 6 can be lifted.

[0087] By providing the hook portion 14, the hammer 6 can be lifted without torque (load) by using the principle of leverage with the shaft 3 as a fulcrum.

[0088] Also, the adhesion prevention device can be provided on each of the left and right conveyor chains. The left and right conveyor chains can be provided separately, or the left and right conveyor chains can be provided in conjunction with each other.

[0089] When installing separate adhesion prevention devices on the left and right, adjust the positions where the left and right cams contact the roller so that the hammers hit the roller at the same time.

[0090] As the chain conveyor continues to operate, if a faulty bend in the chain occurs, causing a difference in length between the left and right chains, the hammers will not be able to strike the rollers at the same time, and the abnormality can be confirmed by the sound.

[0091] In addition, sound can be converted into light signals, making it possible to check for differences in chain length even when operated remotely. For example, by picking up the sound of a hammer with a microphone, converting it into an electrical signal, and lighting a lamp, it is possible to determine the difference in length between the left and right chains.

[0092] Furthermore, if the difference in length between the left and right chains is due to a problem with either the left or right chain, the problem can be solved by concentrating the operation of the adhesion prevention device on only one of the left or right chains.

[0093] By maintaining the chain in good condition for a longer period of time, maintenance time is reduced and the chain parts last longer.

[0094] In addition, since there is no bending fixation, the rollers themselves can rotate smoothly, and friction with the rail caused by poor rotation is eliminated, and wear due to friction is also reduced.

[0095] In addition, because the chain is in a normal condition, it is possible to monitor the chain tension and measure the exact tension, which increases the accuracy of "visualization" of the conveyor chain's operating status, making it a device that can more accurately predict changes in the conveyor over time and failures.

[0096] Furthermore, by preventing bending defects in the conveyor chain, the forward and reverse rotation of the conveyor chain can be automated, making the conveyor operation more efficient.

[0097] Here, an example of the attachment state of the anti-adhesion device for a conveyor chain of the present invention is shown.

[0098] Fig. 7 is an explanatory diagram of the entire side of a scraper conveyor, and is a diagram illustrating an example of the installation state of the adhesion prevention device for a conveyor chain of the present invention. The scraper conveyor shown in Fig. 7 is of the top return type, but it can also be used for other scraper conveyors.

[0099] In Fig. 7, 15 is a casing, which is a conveying path for conveyed objects. 16 is a drive shaft, which is provided inside the casing 15. 17 is a driven shaft, which rotates via a conveyor chain in response to the drive from the drive shaft 16. This driven shaft 17 rotates in response to the drive from the drive shaft 16. 18 is a head sprocket, which transmits the rotation of the drive shaft 16. 19 is a motor, which drives the head sprocket 18. 20 is a tail sprocket, which corresponds to the head sprocket 18 and plays a role in transmitting the drive of the drive shaft 16 to the driven shaft 17.

[0100] The conveyor chain can be moved along the guide rail 21.

[0101] Reference numeral 7 denotes a conveyor chain and 9 denotes a roller. A chain is formed by connecting a plurality of conveyor chains 7 and rollers 9. Only a portion of the conveyor chains and rollers are shown in FIG. 7.

[0102] Reference numeral 23 denotes a scraper, which is attached to the conveyor chain 7 and transports the transported object. A plurality of scrapers 23 are provided at regular intervals. The conveyor chain 7 plays a role in transmitting the rotation of the drive shaft 16, which moves the scraper 23, to the driven shaft 17.

[0103] Reference numeral 24 denotes an inlet for incineration ash. Reference numeral 25 denotes incineration ash that is input from the inlet 24 for incineration ash. The incineration ash 25 is transported by a scraper 23 and carried to a discharge outlet 26. The incineration ash also includes ash that contains moisture.

[0104] The scraper conveyor shown in Figure 7 is a type of conveyor known as a top return type, and as shown in the figure, the scraper 23 moves in the direction of the arrow A as it passes through the top, and as it passes through the bottom, the scraper 23 transports the incineration ash fed from the inlet 24 for incineration ash and moves it to the outlet 26.

[0105] In the case of a top-return type scraper conveyor, the scraper 23 moving at the top in the direction of arrow A is not carrying any goods, while the scraper 23 moving at the bottom in the direction of arrow B is carrying goods.

[0106] As shown in FIG. 7, by installing the conveyor chain adhesion prevention device of the present invention, the rollers of the conveyor chain can be struck by the adhesion prevention device in accordance with the movement of the conveyor chain. [Industrial Applicability]

[0107] To provide a device for preventing adhesion of ash and the like that has entered into gaps in a conveyor chain, and capable of reducing wear of the conveyor chain without causing bending failure of the conveyor chain by applying impact with a hammer.

[0108] In addition, in this invention, the cam and arm are slidable on the shaft, so that excessive torque (stress) is not applied to the shaft. Also, since it moves in sync with the movement of the conveyor chain, it is a mechanical structure and the adhesion prevention device can be easily installed on existing conveyors. Furthermore, since it is a device that does not require electrical signals or control, it also saves energy.

[0109] By ensuring that the conveyor chain operates smoothly and measuring the tension on the conveyor chain, it is possible to determine the condition in which the conveyor is being operated and transported, which can contribute to "visualization of operation," "prediction of failures," "operational support," "labor saving," and "decarbonization."

[0110] Furthermore, by preventing bending defects in the conveyor chain, the forward and reverse rotation of the conveyor chain can be automated, making the conveyor operation more efficient. [Explanation of symbols]
