Description

  The present invention relates to a transfer system that transfers an object to be crushed, such as concrete waste, to a crushing apparatus, such as an impact crusher, and puts it into the apparatus.

  In a crushing device such as an impact crusher, a crusher for crushing is moved inside the casing of the device, the crushing target object is collided with the crusher and crushed, or against a repellent plate fixedly installed inside the casing, It has a mechanism for further colliding and crushing the object to be crushed by hitting the striker.

  In such a crushing device, the crushing object is transferred by a belt conveyor or the like, and the crushing object sent out from the end of the conveyor and dropped is introduced into the inlet of the crushing device, so that the crushing object is continuously supplied. It is common for the system to be supplied to

  The crushing device crushes an object to be crushed from the inlet by one or more collisions with a striker or a repulsion plate, and then drops the crushed piece to the lower part, and then crushes the fragment from the outlet of the casing. To the outside.

  The striker and the repulsion plate in this conventional crushing apparatus directly collide with the object to be crushed, and thus wear with the use of the crushing apparatus. When the striker and the repellent plate are worn, the crushing efficiency of the object to be crushed decreases. Generally, the striker and the repellent plate are provided so as to be detachable and replaceable. The Examples of such conventional crushing apparatuses include those disclosed in JP 2007-203153 A and JP 2008-88671 A.

JP 2007-203153 A JP 2008-88671 A

  Conventional crushing devices are shown in the above patent documents, and as a main use, crush raw material stones obtained at quarries and the like as crushing objects to obtain gravel and crushed stones of appropriate size. Is mentioned. In addition, in order to reuse as recycled materials, it has been often done in the past to crush concrete waste (concrete waste material) and asphalt waste (asphalt waste material) as crushing objects with a crushing device to make fine pieces. Yes.

  Among these, concrete debris and asphalt debris may be mixed with metal foreign matters such as reinforcing bars and scraps due to their origin as waste materials. When these foreign objects are thrown into the crushing device, these metal foreign materials are harder than stone and concrete, which are normal objects to be crushed, and will cause abnormal wear and breakage of the crushing device striker and repulsion plate. Since it is easy to invite, it was necessary to remove these foreign substances as much as possible before throwing them in.

  In general, the removal of such metal foreign matter is to detect the foreign matter with a metal detector or the like from the object to be crushed, and when the foreign object is detected, the crushing device and the conveyor for supplying the object to be crushed are stopped, Conventionally, an operator manually removes foreign matter.

  However, such conventional manual removal requires a lot of labor and labor, and by stopping the crushing device etc., crushing cannot be performed during that time, and the efficiency of crushing work is greatly reduced, and The problem was that the cost would increase.

  In addition, in the conventional crushing device, the state of charging of the crushing object from the supply conveyor to the inlet is not particularly changed, and as a result, the crushing object first comes into contact with the striker. Since the change does not change, the direction in which the object to be crushed collides with the striker and is repelled hardly changes, and the position where the object to be crushed contacts and collides with the striker and the repellent plate is likely to be biased.

  For this reason, it is easy for the striker and the repellent plate to be worn away, and whether the hard object is mixed with the object to be crushed or not, Although wear has progressed locally and most of the impactor and repellent plate are below the wear limit and can be crushed normally, the wear limit is partially reached and replacement is forced. However, there was a problem that the operating cost would be excessive.

  The present invention has been made in order to solve the above-mentioned problems, and can appropriately operate each conveyor for transferring an object to be crushed so that foreign matters are not put into the crushing apparatus, and abnormal wear and breakage of each part of the crushing apparatus can be prevented. It aims at providing the transfer system for crushing apparatuses.

  The crushing device transfer system according to the present invention includes a first conveyor that transfers a crushing object toward a crushing device that crushes the crushing object, and a first conveyor between the first conveyor and the crushing device. A second conveyor for transferring a crushing object from at least one end of the crushing apparatus and transferring the crushing object from one end near the crushing apparatus to the crushing apparatus, Regarding the operating state of the second conveyor, there are a forward transfer state in which the transfer direction of the second conveyor is close to the crushing device inlet and a reverse transfer state in which the transfer direction is away from the crusher inlet. A control unit that performs control to switch to any one of the above, and a foreign object that is connected to the control unit and that is mixed in the crushing object to be transferred can be detected. And a foreign matter detection unit capable of sending predetermined control information to the control unit, the first conveyor transfers the object to be crushed, and the second conveyor is in a forward transfer state and is crushed. When the control unit receives the predetermined control information from the foreign matter detection unit while sending the object toward the inlet of the crushing device, the foreign matter transferred by the first conveyor is transferred to the first conveyor end. When the second conveyor is transferred to the second conveyor, the second conveyor is switched from the forward transfer state to the reverse transfer state, and the second conveyor discharges the foreign matter from the other end of the conveyor in the reverse transfer state. When sent to the road, the control unit switches the second conveyor from the reverse transfer state to the forward transfer state.

  As described above, according to the present invention, when the foreign matter mixed in the object to be crushed is detected by the foreign matter detection unit, when the foreign matter is transferred from the first conveyor to the second conveyor, the control unit By switching the conveyor from the forward transfer state to the reverse transfer state and allowing the foreign matter on the second conveyor to be discharged away from the crushing device input port, the foreign material can be discharged from the second conveyor to the crushing device input port. When the foreign matter is hard, such as metal, contact between each mechanism inside the crushing device and the foreign matter, and abnormal wear and damage of the mechanism based on the collision can be prevented. The durability of the battery can be improved, and the replacement frequency of consumable parts can be reduced to improve the economy.

  Further, in the crushing device transfer system according to the present invention, the control unit can adjust and control the transfer speed of the second conveyor as necessary, and the predetermined control information from the foreign matter detection unit can be controlled. Upon receipt, the transfer speed of the second conveyor is increased from the beginning, and when the second conveyor sends out foreign matter from the other end of the conveyor to the predetermined discharge path, the control unit moves the second conveyor in the reverse direction. In addition to switching from the transfer state to the forward transfer state, speed adjustment is performed to return to the original transfer speed simultaneously with the change or after a predetermined time has elapsed.

  As described above, according to the present invention, when the foreign matter mixed in the object to be crushed transferred by the first conveyor is detected by the foreign matter detection unit, the foreign matter is detected by increasing the transfer speed of the second conveyor. From the first conveyor to the second conveyor, foreign matter is transferred from the first conveyor to the second conveyor, and the crushing object transferred from the first conveyor to the second conveyor is reduced in density on the second conveyor, Increasing the proportion of the object to be crushed from the second conveyor to the crushing device inlet, foreign matter was transferred from the first conveyor to the second conveyor, and the second conveyor was switched to the reverse transfer state. At this point, the amount of objects to be crushed on the second conveyor can be reduced, and the second conveyor can be moved more smoothly so that foreign substances can be transported and discharged more easily. And as little as possible amount of crushed objects issued, proceed more efficiently crushed while suppressing losses. Moreover, after the foreign matter is discharged and the second conveyor is switched to the forward transfer state by the amount that can reduce the objects to be crushed on the second conveyor, the objects to be crushed are placed on the second conveyor from the first conveyor. Even if it moves, the crushing object on the second conveyor does not become excessive, and even if the first conveyor is not temporarily stopped, the crushing object can be transported by the second conveyor without difficulty. The control mechanism related to the transfer can be simplified to reduce the cost.

  Further, in the crushing device transfer system according to the present invention, if necessary, the second conveyor can move at least one end in a lateral direction within a predetermined range based on the control of the control unit, and the control unit However, during the operation of the crushing device or at a predetermined timing between the operations, the one end of the second conveyor is moved laterally with respect to the crushing device, and the crushing object to be sent out from the one end of the second conveyor The arrival position at the crusher inlet is changed.

  As described above, according to the present invention, the end position of the second conveyor is moved laterally at a predetermined timing with respect to the crushing device, and the arrival position of the crushing object coming out of the second conveyor at the crushing device inlet is determined. By being able to adjust to a position different from that before, it is possible to change the collision position relationship between the crushing object and each mechanism in the crushing device by changing the progress state of the crushing object in the crushing device, and the collision position is not partially biased As a result, the wear parts can be distributed evenly, the wear is not concentrated, the time to reach the wear limit of the consumable parts is lengthened, the replacement frequency of the consumable parts is reduced, and the operating cost of the crushing device can be reduced. .

  Moreover, the crushing device transfer system according to the present invention is also capable of detecting a foreign object when the foreign object detection unit does not detect a foreign object while transferring the object to be crushed by the first conveyor. Is sent to the control unit, the control unit acquires the transfer execution state of the first conveyor based on the control information from the foreign matter detection unit, During the transfer, every time a predetermined time set in advance elapses, the position of one end of the second conveyor is sequentially changed with the elapsed time as the predetermined timing.

  As described above, according to the present invention, based on the control information from the foreign matter detection unit, the control unit transfers one object of the second conveyor every predetermined time while the first conveyor transfers the object to be crushed. The crushing device can be considered to be in operation while it is being transferred on the first conveyor by changing the position at which the crushing object coming from the second conveyor reaches the crushing device inlet sequentially. Therefore, throughout the operation state of the crushing device, the collision position between the crushing object and each mechanism in the crushing device is shifted every predetermined time, and the collision position is equalized without concentrating and wear is not biased. Proceeding evenly, the time to reach the wear limit of the consumable parts is made as long as possible, the consumable parts can be used more efficiently and the cost can be reduced. In addition, it is possible to realize control that repeats the transfer state adjustment at every elapse of a predetermined time corresponding to the continuation of the operation state of the crushing device without directly monitoring the crushing device by the control unit, thereby simplifying the control configuration and reducing the cost.

  The crushing device transfer system according to the present invention can adjust the transfer speed at least in the forward transfer state at least based on the control of the control unit, if necessary, The control unit changes the transfer speed in the forward transfer state of the second conveyor at a predetermined timing during the operation of the crushing device or between operations, and the crushing object to be sent out from one end of the second conveyor The arrival position at the crusher inlet is changed.

  As described above, according to the present invention, the transfer speed of the second conveyor is changed at a predetermined timing with respect to the crushing apparatus, and the arrival position of the crushing object coming out of the second conveyor at the crushing apparatus input port is changed to that. Can be adjusted to different positions, changing the advancing state of the crushing object in the crushing device, changing the collision position relationship between the crushing object and each mechanism in the crushing device, and the collision position is not partially biased, Wear parts can be distributed evenly, and the amount of time that it takes to reach the wear limit of consumable parts can be lengthened, and the operating cost of the crushing apparatus can be reduced by reducing the frequency of replacement of consumable parts.

  Moreover, the crushing device transfer system according to the present invention is also capable of detecting a foreign object when the foreign object detection unit does not detect a foreign object while transferring the object to be crushed by the first conveyor. Is sent to the control unit, the control unit acquires the transfer execution state of the first conveyor based on the control information from the foreign matter detection unit, During the transfer, every time a predetermined time set in advance elapses, the transfer speed in the forward transfer state of the second conveyor is sequentially changed with the elapsed time as the predetermined timing.

  As described above, according to the present invention, based on the control information from the foreign matter detection unit, the transfer rate of the second conveyor every predetermined time while the first conveyor transfers the object to be crushed in the control unit. By changing the arrival position of the object to be crushed from the second conveyor at the inlet of the crushing device, the crushing device can be regarded as operating while it is being transferred on the first conveyor. During the operation of the crushing device, the collision position between the crushing object and each mechanism in the crushing device is shifted every predetermined time, and the collision position is equalized without concentrating, and the wear is evenly distributed. The time until the wear limit of the consumable parts is reached is made as long as possible, and the consumable parts can be used more efficiently to reduce the cost. In addition, it is possible to realize control that repeats the transfer state adjustment at every elapse of a predetermined time corresponding to the continuation of the operation state of the crushing device without directly monitoring the crushing device by the control unit, thereby simplifying the control configuration and reducing the cost.

  Further, the crushing device transfer system according to the present invention is disposed so as to surround the inlet of the crushing device as necessary, and one end portion of the second conveyor is positioned in the vicinity of the opening provided in the upper portion. A guide unit that guides the object to be crushed from the one end to the input port of the crushing device, and a suspension supported at an upper portion between the one end of the second conveyor and the input port of the crushing device in the guide unit. A plurality of suspended bodies that are arranged in a lowered state and that can be brought into contact with the object to be crushed from the one end of the second conveyor, and one end of each suspended body is connected to the guide section. A plurality of actuators that are arranged in a state and that are capable of adjusting the suspension length of the suspension body by displacing one end portion of the suspension body based on the control of the control unit, wherein the suspension body is arranged in the lateral direction. Divided into multiple groups, and The suspension length can be adjusted by the actuator, and one or more sets of suspension bodies on one side in the horizontal direction and one or more sets of suspension bodies on the other side in the lateral direction, The operating state of the actuator is made different so that the hanging lengths of the suspended bodies are different, and the control unit operates the actuator at a predetermined timing during the operation of the crushing device or between the operations. The relationship between the suspended length of the suspended body on the other side and the suspended body on the other side is changed so that the contact state between the suspended body and the object to be crushed is the same between the suspended body on the one side and the suspended body on the other side. In other words, the arrival position at the crushing device inlet of the crushing object fed from one end of the second conveyor is changed.

  As described above, according to the present invention, a plurality of sets of suspension bodies that come into contact with the object to be crushed from the conveyor are arranged in the guide portion that surrounds the inlet of the crushing apparatus so that the suspension length can be adjusted, and the lateral direction is adjusted. Change the hanging length of the suspended body on one side and the other side, and swap the relationship between the suspended length of the suspended body on the one side and the other side in the horizontal direction at a predetermined timing with respect to the crushing device. By changing the contact state between the object to be crushed and the suspended body, the arrival position of the object to be crushed at the crushing device inlet can be adjusted to a position different from the previous position, and the progress state of the object to be crushed in the crushing device can be adjusted. By changing the collision position relationship between the object to be crushed and each mechanism in the crushing device, the collision position is not partially biased, and as a result, wear points can be evenly distributed, and wear is not concentrated. Parts wear A longer time to reach the limit, can be reduced operating costs of the crushing apparatus to reduce the frequency of replacement of consumable parts.

  Further, the crushing device transfer system according to the present invention transfers the crushing object toward a crushing device that crushes the crushing object, and moves the crushing object from the end near the crushing device to the inlet side of the crushing device. One or a plurality of conveyors to be sent out and an inlet of the crushing device are arranged so as to surround one end portion of the conveyor closest to the crushing device in the vicinity of the opening provided in the upper portion, and the one end portion is ejected. A guide unit that guides the crushed object to the inlet of the crushing device, and a guide portion that communicates with the guide unit at a predetermined position on the side of the crushing device and below the one end of the conveyor. From a first predetermined position between the one end of the conveyor and the inlet of the crushing device in the guide section, between the one end of the conveyor and the discharge path. Up to the second predetermined position A substantially plate-shaped switching damper disposed so as to be tiltable at least within a range of degrees, and tilting the switching damper so that the switching damper is in the second predetermined position and the object to be crushed can advance only to the inlet A control unit for controlling switching between a normal charging state and a foreign matter discharge state in which the switching damper is in the first predetermined position and foreign matter can travel only to the discharge path, and connected to the control unit. A foreign matter detection unit capable of detecting foreign matter mixed in the object to be crushed transferred by the conveyor, and capable of sending predetermined control information including the foreign matter detection result to the control unit at least when foreign matter is detected. When the control unit receives the predetermined control information from the foreign matter detection unit while the switching damper is in the normal input state, the foreign matter transferred by the conveyor comes out of the one end portion. Sometimes, the switching damper is tilted to switch from the normal input state to the foreign matter discharge state, and when the foreign matter enters the discharge path, the control unit tilts the switching damper to normal discharge state from the foreign matter discharge state. Is switched to.

  As described above, according to the present invention, when the foreign matter mixed in the object to be crushed is detected by the foreign matter detection unit, the control unit removes the switching damper from the normal input state when the foreign matter exits the one end of the conveyor. By switching to the foreign matter discharge state and allowing foreign matter falling in the guide to be discharged toward the discharge path instead of the crushing device inlet, it is not necessary to put the foreign material into the inlet of the crushing device. When it is hard, the contact between each mechanism inside the crushing device and foreign matter, the abnormal wear and damage of the mechanism based on the collision can be prevented, the durability of the consumable parts worn in the crushing device can be improved, and Economics can be improved by reducing replacement frequency.

(First embodiment of the present invention)
Hereinafter, the crushing device transfer system according to the first embodiment of the present invention will be described with reference to FIGS. In the present embodiment, an example in which the crushing device is an impact crusher will be described.
In each of the drawings, the crushing device transfer system 1 according to the present embodiment includes a first conveyor 20 that transfers a crushing object 90 toward the crushing device 10 and a crushing object 90 from the end of the first conveyor 20. Is transferred by the second conveyor 30 that can be transferred to the crushing apparatus 10 side, a control unit 40 that performs control for switching the operation state of the second conveyor 30, and the first conveyor 20. In this configuration, the foreign matter detection unit 50 capable of detecting the foreign matter 91 mixed in the crushing object 90 to be detected and the guide unit 60 disposed so as to surround the inlet 15 of the crushing device 10 are provided.

  The crushing device 10 includes a rotor 12 that is rotatably supported inside a casing 11, a plurality of striking members 13 that protrude from the outer periphery of the rotor 12 and rotate integrally with the rotor 12, a rotor 12 inside the casing 11, A plurality of repulsion plates 14 that are installed around the hitting element 13 and are fixed. The crushing object 90 that is thrown into the hitting element 13 collides with the hitting element 13 or is shattered off by hitting the hitting element 13. The object 90 is further crushed by colliding with the repulsion plate 14. About the mechanism of each part of the crushing apparatus, it is the same as that of a known crushing apparatus as an impact crusher, and detailed description is abbreviate | omitted.

  The first conveyor 20 transports the crushing object 90 toward the crushing apparatus 10 that crushes the crushing object 90. The structure of the conveyor itself is the same as that of a known belt conveyor, and detailed description thereof is omitted. However, the first conveyor is not limited to the belt conveyor, and may be other transfer means such as a screw conveyor or a vibrating conveyor (vibrating feeder) as long as it has a function of transferring the object to be crushed.

  The second conveyor 30 is arranged between the first conveyor 20 and the crushing device 10 so that the crushing object 90 is transferred from the end of the first conveyor 20 and can be transferred to at least the crushing device side. In this configuration, the object to be crushed 90 is sent out from the one end near the crushing apparatus to the inlet 15 side of the crushing apparatus 10. Then, the second conveyor 30 has a forward transfer state in which the transfer direction of the crushing object 90 is close to the crushing device input port 15 and a reverse transfer state in which the transfer direction is a direction away from the crushing device input port 15. Each can be switched.

  The structure of the conveyor itself of the second conveyor 30 is the same as that of a known belt conveyor capable of switching between normal and reverse rotation, and detailed description thereof is omitted. However, this second conveyor is not limited to a belt conveyor, and if it has a function of transferring objects to be crushed in two directions, a vibrating conveyor (vibrating feeder), a gravity conveyor, a shooter, etc. Other transfer means may be used.

  The second conveyor 30 is supported so that one end near the crushing device 10 can move in a predetermined range in the lateral direction, and the actuator 31 is operated based on the control of the control unit 40 to the crushing device 10. The position is adjusted by laterally moving one end. By adjusting the position of one end portion of the second conveyor 30 in the horizontal direction, the arrival position of the crushing object 90 fed from the one end portion of the second conveyor 30 at the crushing device inlet 15 can be changed in the horizontal direction. Yes (see FIG. 4).

In addition, about the 2nd conveyor 30, although it is set as the structure supported so that the one end part near the crushing apparatus 10 may be moved to a horizontal direction, it is not restricted to this, The other which was separated from the crushing apparatus 10 instead of one end part Support the end to be movable in the horizontal direction, move the other end sideways with a predetermined actuator to change the transfer direction of the object to be shredded, and load the shredder into the shredder The reaching position at the mouth 15 may be shifted laterally.
On the lower side near the other end of the second conveyor 30, a discharge path 32 that receives and discharges the foreign matter 91 that has come out from the end of the second conveyor 30 is provided.

  The control unit 40 has a forward transfer state in which the transfer direction of the second conveyor 30 approaches the input port 15 of the crushing device 10 and a transfer direction of the crushing device input port. 15 is configured to perform control to switch to one of the reverse transfer states in a direction away from 15.

  Specifically, when the foreign object 91 is detected by the foreign object detection unit 50, the control unit 40 transfers the foreign object 91 transferred by the first conveyor 20 from the end of the first conveyor 20 to the second conveyor 30. At times, the second conveyor 30 is switched from the forward transfer state to the reverse transfer state. And if the 2nd conveyor 30 made into the reverse transfer state sends out the foreign material 91 from the other end part of the conveyor to the discharge path 32, the control unit 40 moves the second conveyor 30 from the reverse transfer state to the forward transfer state. Switch again.

  In addition, the control unit 40 can adjust and control the transfer speed of the second conveyor 30. Specifically, when receiving the predetermined control information from the foreign object detection unit 50, the control unit 40 performs control to increase the transfer speed of the second conveyor 30 from the beginning. When switching the second conveyor 30 thereafter from the forward transfer state to the reverse transfer state, the transfer direction is switched with the magnitude of the speed (absolute value) when previously increased from the initial value as it is as the target value. Performs speed adjustment control. And the control part 40 performs control which switches the 2nd conveyor 30 from a reverse transfer state to a forward transfer state, when the 2nd conveyor 30 sends out a foreign material to the discharge path 32 from the other end part of the conveyor. In this case as well, the transfer direction is switched and the speed is adjusted with the previous transfer speed as the target value after switching. The control unit 40 performs a speed adjustment for returning the second conveyor 30 to the original transfer speed after a lapse of a predetermined time from the switching of the transfer direction, thereby causing the second conveyor 30 to perform normal transfer without detecting foreign matter. Return to the state.

  Moreover, the control part 40 moves one end part of the 2nd conveyor 30 sideways with respect to the crushing apparatus at the predetermined timing during the operation | movement of the crushing apparatus 10, or between operations, and from the one end part of the 2nd conveyor 30. Control is performed so that the arrival position of the crushing object 90 to be sent out at the crushing device inlet 15 is changed from the previous position. In detail, every time a predetermined time set in advance after the crushing device 10 is operated, the elapsed time is set to the predetermined timing so that the lateral position of one end of the second conveyor 30 is sequentially changed. Let

  The predetermined time that defines the timing of changing the lateral position of the one end of the second conveyor 30 by the control unit 40 is a time lapse in which a certain amount of wear can be expected from consumable parts such as a striker and a repellent plate of the crushing device 10. Is set in advance to correspond to In addition, the degree of wear of each consumable part of the crushing device is directly detected by a sensor or the like, and when the predetermined wear amount is reached, the lateral position of one end of the second conveyor 30 is changed at that timing. It doesn't matter.

  The foreign matter detection unit 50 is connected to the control unit 40 and is disposed on the first conveyor 20, and can detect a metallic foreign matter 91 mixed in the crushing object 90 transferred by the first conveyor 20. At least when a foreign object is detected, predetermined control information including this foreign object detection result is sent to the control unit 40. The mechanism for detecting a foreign object is the same as that of a known metal detector using electromagnetic induction or the like, and detailed description thereof is omitted.

  Note that the number of foreign matter detection units is not limited to one, and a plurality of foreign matter detection units may be provided, and the arrangement location is not limited to the first conveyor, but may be provided at other positions. In particular, when a plurality of foreign matter detection units are provided, it is possible to detect foreign matters other than metal that can affect the crushing device by using a sensor other than a metal detector as the detection unit. Also, the foreign object detection target location can be not only the first conveyor but also the second conveyor and its vicinity including the transfer location from the first conveyor. For example, a detection method such as image analysis by acquiring an image of a crushing object or the like with an imaging means such as a video camera from a position slightly away from a second conveyor immediately after transfer from the first conveyor as a detection target It is possible to detect foreign matters, and it is possible to more appropriately detect foreign matters that often appear on the surface due to changes in the positional relationship with the object to be crushed when the conveyor is transferred. In order to improve the detection accuracy when detecting the foreign matter by the foreign matter detection unit, the transfer speed of the conveyor can be reduced or the conveyor can be temporarily stopped so that the movement of the foreign matter to be detected becomes small.

  The foreign matter detection unit 50 sends another control information not including the foreign matter detection result to the control unit 40 even when the foreign matter 91 is not detected during the transfer of the crushing object 90 by the first conveyor 20. It is the structure to do.

  Based on the control information from the foreign object detection unit 50, the control unit 40 acquires the transfer execution state of the first conveyor 20. The operation of the first conveyor 20 corresponds to the operation of the crushing device 10, and the crushing device 10 can be regarded as operating while the transfer on the first conveyor 20 is performed. Whether or not the crushing device 10 is operated indirectly can be determined from the transfer execution state of the conveyor 20, and the position adjustment control of one end of the second conveyor 30 can be appropriately performed according to the operation state of the crushing device 10. .

  The guide portion 60 is arranged in a substantially cylindrical shape so as to surround the inlet 15 of the crushing apparatus 10, and one end portion of the second conveyor 30 is positioned in the vicinity of the opening provided in the upper portion. It is the structure which guides the crushing object 90 which came out to the inlet 15 of the crushing apparatus 10.

  Along with this guide part 60, a plurality of chains 70 as suspension bodies in which the upper part is supported between the one end part of the second conveyor 30 in the guide part 60 and the inlet 15 of the crushing device 10 are arranged. Established. Further, the guide unit 60 is provided with a plurality of actuators 80 that are connected to one end of each chain 70.

  Note that a discharge path 61 and a switching damper (not shown) for switching the path of the object to be crushed 90 are provided at the lower part of the guide part 60, and when the foreign matter 91 enters the guide part 60 by mistake, In this mechanism, the foreign matter 91 is switched to advance to the discharge path 61 instead of the input port 15.

  The chain 70 is a chain of a predetermined length that is connected to a large number of metal rings and does not break even if it collides with the object 90 to be crushed, and is one end of the second conveyor 30 in the guide section 60. It is the structure arrange | positioned in the suspended state by which the upper part was supported between the insertion part and the inlet 15 of the crushing apparatus 10. FIG. The chain 70 is hung at a predetermined position in the middle part thereof on a support part 62 installed on the guide part 60, and one end part of the chain is connected to an actuator 80 on the side of the support part 62, so that the suspension length can be adjusted. In such a state, the arrangement is suspended from the support portion 62 downward.

  Further, the chain 70 is arranged in a curtain shape between the one end portion of the second conveyor 30 and the inlet 15 of the crushing device 10, so that the object to be crushed from the one end portion of the second conveyor 30. The mechanism 90 is configured to be able to come into contact with the object 90 as necessary, and to prevent the object 90 to be shattered inside the casing of the crushing apparatus 10 from jumping out from the input port 15.

  A plurality of the actuators 80 are arranged in a state where they are connected to one end of each chain 70 in the guide part 60, and the chain 70 is suspended by suspending the chain 70 based on the control of the control unit 40. Can be adjusted. The structure of the actuator 80 is a known fluid pressure cylinder that moves the plunger back and forth with liquid pressure introduced from the outside, and detailed description thereof is omitted. By connecting one end of the chain 70 to the plunger of the actuator 80 constituting the fluid pressure cylinder, the position of the one end of the chain 70 can be moved to adjust the hanging length of the chain 70.

  Next, the use state of the crushing device transfer system based on the above configuration will be described. As a premise, corresponding to the operation related to crushing of the crushing device 10, the crushing object 90 is supplied to the end of the first conveyor 20 on the side away from the crushing device 10 by a supply means (not shown). It is assumed that the device 10 can continuously crush the crushing object 90.

  Corresponding to the operation related to crushing of the crushing device 10, the first conveyor 20 is also operated to transfer the crushing object 90 toward the crushing device 10. When the foreign matter detection unit 50 provided on the first conveyor 20 cannot detect foreign matter from the crushing object to be transferred, the second conveyor located between the first conveyor 20 and the crushing device 10. 30, the crushing object 90 drops and is transferred from the end of the first conveyor 20, and the crushing object is crushed by the second conveyor 30 in the forward transfer state in which the transfer direction is close to the crushing device inlet 15. The object 90 is transferred to the crusher side. Then, the object to be crushed falls from one end of the second conveyor 30 near the crushing device, and travels to the inlet 15 of the crushing device 10 through a region where the chain 70 is located in the guide unit 60.

In the crushing device 10, like the known impact crusher, the crushing object 90 thrown into the casing 11 from the inlet 15 is made to collide with the striker 13 that rotates integrally with the rotor 12, or hit the striker 13 to repel it. The crushing object 90 is further collided with the repulsion plate 14, and the crushing object 90 is crushed by such one or more collisions to obtain a crushing piece having a desired size.
After crushing, the crushed pieces fall to the lower part of the casing 11 and are discharged from the outlet of the casing 11 to the outside.

  As described above, each process from the transfer of the crushing object 90 to the crushing of the crushing object 90 by the crushing apparatus 10 is continuously performed, and the crushing apparatus 10 is normally operated to crush the crushing object 90. In accordance with this, the crushing object 90 is transferred by the conveyors 20 and 30.

  When the crushing object 90 is transferred by the first conveyor 20 and the second conveyor 30, the foreign object detection unit 50 detects the foreign object while the crushing object 90 is transferred by the first conveyor 20. Control information that does not include the result is sent to the control unit 40. The control unit 40 can acquire and recognize that the first conveyor 20 is in the transfer execution state based on the control information that does not include the foreign object detection result. Moreover, since the operation | movement which concerns on transfer of the 1st conveyor 20 respond | corresponds with the action | operation of the crushing apparatus 10, the control part 40 can recognize simultaneously that it is the operation | movement state also about the crushing apparatus 10 similarly to a 1st conveyor. .

  The control unit 40 is preset in this transfer execution state while the transfer execution state continues at a predetermined timing during operation of the crushing device, specifically, the first conveyor 20 regarded as synonymous with the operation of the crushing device. When the predetermined time elapses, the actuator 31 in the second conveyor 30 is actuated at that time, and one end of the second conveyor 30 is moved laterally with respect to the crushing device 10, so that the second conveyor 30 The arrival position of the crushing object fed out from one end of the crushing device at the crushing device inlet 15 is changed to a position different from the previous position.

  After this, the control unit 40 is connected to the end of the second conveyor 30 every time the predetermined time elapses while the crushing in the crushing apparatus 10 and the transfer on the first conveyor 20 are performed. The position is changed, and the arrival position of the crushing object 90 at the crushing device inlet 15 is moved every predetermined time. As a result, while the operation related to crushing of the crushing device 10 continues, the collision position between the crushing object 90 and the striker or the repulsion plate in the crushing device can be shifted every predetermined time, and the collision position is not concentrated and evenly distributed. The wearer and repellent plate wear is evenly distributed evenly, and the time required to reach the wear limit of the consumable component striker and repellent plate is made as long as possible to make these consumable components more efficient. Can be used.

  On the other hand, when the crushing apparatus 10 and the conveyors 20 and 30 are operating, and the foreign object 91 is mixed in the crushing object 90 transferred by the first conveyor 20, the foreign object detection unit 50 detects the crushing object. The foreign matter 91 mixed in 90 is detected, and control information including the foreign matter detection result is sent to the control unit 40.

  When the control unit 40 receives the control information including the foreign object detection result from the foreign object detection unit 50, the control unit 40 adjusts and controls the transfer speed of the second conveyor 30 to increase the transfer speed from the beginning. In addition, when the foreign material 91 transported by the first conveyor 20 is transferred from the end of the first conveyor 20 to the second conveyor 30, more specifically, the control unit 40 detects the foreign material in the first conveyor 20. When the estimated elapsed time from the detection of the foreign matter until the foreign matter exits the first conveyor end calculated by the control unit 40 based on the detection position and the known transfer speed of the first conveyor 20, the second The conveyor 30 is switched from the forward transfer state to the reverse transfer state in which the transfer direction of the second conveyor 30 is away from the crushing device inlet 15. However, the magnitude of the transfer speed in the second conveyor 30 is adjusted as the target value of the magnitude of the transfer speed is the same as before even after the transfer direction is reversed. It becomes the same size as the transfer speed which was increased from the beginning.

  The second conveyor 30 switched to the reverse transfer state transfers the crushing object 90 and the foreign matter 91 on the conveyor in a direction away from the crushing device inlet 15. Since the transfer speed in the reverse transfer state is the same as the transfer speed increased from the original after the adjustment by the control unit 40, the transfer speed is transferred from the first conveyor 20 to the second conveyor 30. The placement density of the object to be crushed on the second conveyor 30 can be made smaller than usual.

  Then, the second conveyor 30 advances the transfer, and drops and sends out the foreign matter that is farthest from the crushing device inlet 15 on the conveyor toward the discharge path 32 from the other end of the conveyor. At the same time, the control unit 40 switches the second conveyor from the reverse transfer state to the forward transfer state. However, also at this time, the magnitude of the transfer speed in the second conveyor 30 is the same as the magnitude of the transfer speed increased from the beginning after the adjustment by the control unit 40 regardless of the change in the transfer direction. Thereafter, the control unit 40 has passed a predetermined time from the switching from the reverse transfer state to the forward transfer state, and the location where the foreign matter is present on the second conveyor 30 is the first in the second conveyor 30. When reaching the position where the object to be crushed from the conveyor 20 is transferred, the transfer speed is adjusted and controlled to return to the original transfer speed.

  For a while after the foreign matter is detected by the foreign matter detection unit 50, the transfer speed of the second conveyor 30 is increased from the beginning so that the foreign matter is detected and then the first conveyor 20 to the second conveyor. The crushing object transferred from the first conveyor 20 to the second conveyor 30 by the time the foreign matter is transferred to the second conveyor 30 is reduced in the mounting density on the second conveyor 30 and the crushing object second The rate at which the rate of advancement from the conveyor 30 to the crushing device inlet 15 is increased, and foreign matter is transferred from the first conveyor 20 to the second conveyor 30 and the second conveyor 30 is switched to the reverse transfer state. Thus, the amount of objects to be crushed on the second conveyor 30 can be reduced, and the second conveyor 30 can be moved more smoothly so that foreign matters can be transported and discharged without difficulty.

  Even if the object to be crushed is accidentally dropped from the second conveyor 30 and discharged together with foreign objects, the amount of the object to be crushed is reduced as much as possible, the loss is suppressed, and the crushing object is more efficiently performed. It is advanced. Furthermore, after the foreign matter is discharged and the second conveyor 30 is switched to the forward transfer state, even if the crushing object 90 is transferred from the first conveyor 20 to the second conveyor 30, the transfer speed is increased. Since the crushing object 90 on the second conveyor 30 is reduced by increasing the size, the crushing object 90 on the second conveyor 30 is not excessive, and the first conveyor 20 is not temporarily stopped. The transfer of the object 90 to be crushed by the second conveyor 30 can be continued without difficulty.

  The crushing object 90 from which foreign matter has been removed is transferred to the crushing device side by the second conveyor 30 that has been switched to the forward transfer state and the transfer speed has returned to the original state, and falls from one end of the conveyor in the same manner as described above. Then, it goes to the inlet 15 of the crushing device through a certain region of the chain 70 in the guide portion 60.

  Thus, in the crushing device transfer system according to the present embodiment, when the metal foreign matter 91 mixed in the crushing object 90 transferred by the first conveyor 20 is detected by the foreign matter detection unit 50, the foreign matter 91 is detected. When the first conveyor 20 is transferred to the second conveyor 30, the controller 40 switches the second conveyor 30 from the forward transfer state to the reverse transfer state, and the foreign matter 91 on the second conveyor 30 is removed. Since it can be discharged away from the charging port 15 of the crushing device 10, it is not necessary to put the foreign material 91 into the charging port 15 of the crushing device 10 from the second conveyor 30. Can prevent abnormal wear and breakage of the mechanism based on contact with and collision with a foreign object 91, increase the durability of the consumable parts to be worn in the crushing apparatus 10, and reduce the replacement frequency of the consumable parts to improve economy. It is.

  In the crushing device transfer system according to the embodiment, the control unit 40 determines whether or not the crushing device 10 is in an operation state related to crushing, based on information acquired by the foreign matter detection unit 50. Although the transfer execution state of the first conveyor 20 is discriminated and the operation state of the crushing device 10 is indirectly determined, the control system is simplified and independent from the crushing device 10. Not limited to this, the control unit can directly monitor the operation state related to the crushing of the crushing apparatus, and a control configuration in which the timing is set according to the operation can also be adopted.

  Further, in the crushing device transfer system according to the embodiment, when the foreign object 91 is detected by the foreign object detection unit 50, the control unit 40 adjusts and controls the transfer state of the second conveyor 30 to discharge the foreign object 91 and crush it. Although it is set as the structure which does not go to the apparatus 10, in addition to this, when the foreign material detected by the foreign material detection part does not affect the crushing apparatus, it does not necessarily discharge | emit, but the forward transfer state of a 2nd conveyor as it is It can also be set as the structure which inputs and puts into a crushing apparatus. For example, when an image of a crushing object or the like is acquired by an imaging means such as a video camera as a foreign substance detection unit and a foreign object is detected by a detection method such as image analysis, the presence or absence of the influence of the foreign object on the crushing device is also determined If it can be determined that there is no impact on the crushing device for foreign matter, if the control related to the discharge of foreign matter is omitted, the state of sending the crushing object to the crushing device will not easily change, and more Crushing can be carried out efficiently.

  In the crushing device transfer system according to the embodiment, the mechanism for switching the transfer state in the second conveyor 30 discharges the foreign matter 91 and moves the one end of the second conveyor 30 sideways. Although the arrival position in the crushing device inlet 15 of the crushing object 90 is moved and the collision position between the crushing object 90 and each mechanism in the crushing device 10 is not concentrated, the wear is equalized. Only the mechanism for discharging the former foreign matter is a transfer system that omits the mechanism for equalizing the latter wear, or the mechanism for discharging the former foreign matter is omitted, and the latter It may be configured as a transfer system that employs only a mechanism for equalizing the wear.

(Second embodiment of the present invention)
In the crushing device transfer system according to the first embodiment, the control unit 40 controls the second conveyor 30 every time a predetermined time elapses while the crushing device 10 and the first conveyor 20 operate. The position of the one end is changed to shift the arrival position of the object to be crushed in the crushing apparatus 10 so as to equalize the wear on the striker, repulsion plate, etc. in the crushing apparatus. As a form, it replaces with the structure which moves the one end part of the 2nd conveyor 30 to a horizontal direction, or is added to the structure which moves the one end part of the 2nd conveyor 30 to a horizontal direction, FIG.11 and FIG.12. As shown, the transfer speed of the second conveyor 30 is changed under the control of the control unit 40, and the arrival position of the crushing object 90 coming out of the second conveyor 30 at the crushing device inlet 15 is transferred to the second conveyor 30. Changing the direction, it may also be configured to equalize the wear of the embodiment similarly crushing device units.

  In this case, the control unit 40 changes the transfer speed in the forward transfer state of the second conveyor 30 at a predetermined timing during the operation of the crushing device 10, and crushes sent from one end of the second conveyor 30. Control is performed so as to change the arrival position of the object 90 at the crushing device inlet 15 from the previous position. Specifically, every time a predetermined time set in advance after the crushing apparatus 10 is operated, the transfer speed of the second conveyor 30 is changed in order, with the elapsed time as the predetermined timing.

  The predetermined time that defines the timing at which the transfer speed of the second conveyor 30 is changed by the control unit 40 corresponds to the passage of time in which a certain amount of wear can be expected from consumable parts such as a striker and a repellent plate of the crushing apparatus 10. Is preset. In addition, the degree of wear of each consumable part of the crushing device may be directly detected by a sensor or the like, and when the predetermined wear amount is reached, the transfer speed of the second conveyor 30 may be changed at that timing.

  While the crushing device 10 performs crushing and transfer on the first conveyor 20, the control unit 40 changes the transfer speed of the second conveyor 30 each time the preset predetermined time elapses. By moving the arrival position of the crushing object 90 at the crushing device inlet 15 every predetermined time, while the operation related to crushing of the crushing device 10 continues, the crushing object 90 and the striker or repulsion plate in the crushing device are continued. Can be shifted at predetermined time intervals. As a result, there is no concentration of the collision position in each part of the crushing device, the wear of the striker and the repellent plate is evenly progressed, and the time until the wear limit of the striker and the repellent plate as consumable parts is reached is as long as possible. Thus, these consumable parts can be used more efficiently.

(Third embodiment of the present invention)
In the crushing device transport system according to each of the first and second embodiments, the position of the one end portion of the second conveyor 30 and the transfer speed are changed by the control of the control unit 40, and the crushing target in the crushing device 10 is obtained. The arrival position of the object is changed to equalize the wear on the striker, the repulsion plate, etc. in the crushing device. However, the present invention is not limited to this, and the third embodiment is shown in FIGS. Further, based on the control of the control unit 40, the suspension lengths of the plurality of chains 71, 72, 73, 74 as suspension bodies provided in the guide unit 60 on the upper side of the crushing apparatus 10 are set in the lateral direction. Increase / decrease adjustment while giving a difference to change the contact state between the crushing object and the chains 71, 72, 73, 74 and pass the crushing object 90 through the position of the chains 71, 72, 73, 74. In 15 It may be configured to vary the reach position.

  In this case, a plurality of chains 71, 72, 73, 74 arranged in a suspended state with one end connected to the actuator 80 in the guide portion 60 are divided into a plurality of sets in the lateral direction. The suspension length can be adjusted by the actuator 80 for each of a plurality of groups. The operating state of the actuator 80 is made different between a set of a plurality of chains 71 and 72 on one side in the horizontal direction and a set of a plurality of chains 73 and 74 on the other side in the horizontal direction, The hanging lengths of the chains 71, 72, 73, and 74 are different for each group. And with respect to these chains 71, 72, 73, 74, the control unit 40 operates the actuator 80 at a predetermined timing during the operation of the crushing apparatus 10 or between operations, and the other chains 71, 72 on the one side and the like. The relationship of the hanging length with the side chains 73 and 74 is changed so as to be exchanged. Thereby, the contact state of the chains 71, 72, 73, 74 and the crushing object 90 is changed between the one chain 71, 72 and the other chain 73, 74, and from one end of the second conveyor 30. This is a mechanism in which the arrival position of the object to be crushed at the crushing device inlet 15 can be changed from the previous position.

  Specifically, every time a predetermined time set in advance after the crushing device 10 is operated, the control unit 40 operates each actuator 80 with the elapsed time as the predetermined timing, and the one side chain The suspension length is changed so that the relationship of the suspension length between the pair of 71 and 72 and the pair of chains 73 and 74 on the other side is changed from the previous state. For example, the chain 73 and 74 on the other side is hung longer than the chains 71 and 72 on the one side (see FIGS. 13 and 14), and the chain 70 on the one side is the chain 73 on the other side. 74, the operation of each actuator 80 is controlled so that the state in which the suspending length is made longer (see FIGS. 15 and 16) is switched every time a predetermined time elapses.

  The control unit 40 operates the actuators 80 to define the timing for changing the suspension length of the chains 71, 72, 73, 74. The predetermined time is a consumable component such as a striker or a repellent plate of the crushing device 10. Is set in advance so as to correspond to the passage of time in which a certain amount of wear can be expected. In addition, the degree of wear of each consumable part of the crushing device is directly detected by a sensor or the like, and when a predetermined amount of wear is reached, the actuator 80 is operated at that timing to suspend the chain 71, 72, 73, 74. It does not matter if you change the height.

  While the control unit 40 performs crushing in the crushing device 10 and transfer on the first conveyor 20, the chains 71 and 72 on one side and the other side in the lateral direction each time the predetermined time set in advance elapses. , 73, 74 by changing the contact length between the crushing object 90 exiting the second conveyor 30 and the chain 70 by adjusting the suspension length so that the relationship between the suspension lengths is changed. The arrival position of the object 90 at the crushing device inlet 15 can be adjusted to a position different from that at every predetermined time. Thus, while the operation related to crushing of the crushing apparatus 10 continues by changing the state of progress of the crushing object in the crushing apparatus 10, the collision position between the crushing object 90 and the striker or the repulsion plate in the crushing apparatus is changed every predetermined time. Can be shifted. This eliminates the concentration of the collision position at each part of the crushing device, allows the wearer and repellent plate to wear evenly and evenly, and maximizes the time required to reach the wear limit of the striker and rebound plate, which are consumable parts. Thus, these consumable parts can be used more efficiently, and the replacement frequency can be reduced.

  In each of the above embodiments, the suspended body disposed in the suspended state in the guide portion 60 is a chain, but is not limited thereto, and can be disposed in the guide portion 60 in the suspended state. In addition, as long as the suspension length can be adjusted, a plurality of parts other than the chain may be connected in a linear shape to impart deformability, or as a continuous rod-like shape without deformation. It doesn't matter.

(Fourth embodiment of the present invention)
In the crushing device transfer system according to the first embodiment, when the foreign matter 91 is detected by the foreign matter detection unit 50, the control unit 40 adjusts and controls the transfer state of the second conveyor 30, and discharges the foreign matter 91. Although it is set as the structure which does not go to the crushing apparatus 10, as shown in FIG.17 and FIG.18, in addition to this, as shown in FIGS. A discharge path 61 for discharging foreign matter is provided at a predetermined position below one end of the conveyor 30 and communicates with the inside of the guide 60, and between the one end of the second conveyor 30 in the guide 60 and the input port 15. A substantially plate-shaped switching damper 63 that can be tilted at least in an angular range from a first predetermined position between the second predetermined position between one end of the second conveyor 30 and the discharge path 61; The control unit 40 The switching damper 63 is tilted so that the switching damper 63 is in the second predetermined position and the crushing object 90 can advance only to the insertion port 15 (see FIG. 17), and the switching damper 63 is the first one. The crushing device 10 and the conveyors 20 and 30 are operated so as to perform control to switch the foreign matter discharge state (see FIG. 18) in which the foreign matter 91 can travel only to the discharge path 61 at one predetermined position. When the foreign matter detection unit 50 detects the foreign matter, and the control unit 40 receives the control information including the foreign matter detection result from the foreign matter detection unit 50, the foreign matter is discharged from the second conveyor 30 in the first embodiment. In place of the control related to the above, when the foreign matter 91 to be transferred exits one end of the second conveyor 30, the control unit 40 tilts the switching damper 63 to switch from the normal input state to the foreign matter discharge state, May be configured to discharge is advanced to Detchi 61.

  In this case, no foreign matter that would affect the crushing device 10 is detected, and the switching damper 63 is in a normal input state at the normal time when the crushing object 90 comes out from one end of the second conveyor 30, and the foreign matter is Only when the foreign matter reaches the guide unit 60 after being detected, the switching damper 63 is switched to the foreign matter discharge state. When the foreign matter 91 exits the guide portion 60 and enters the discharge path 61 and no longer moves toward the insertion port 15, the control unit 40 tilts the switching damper 63 to switch from the foreign matter discharge state to the normal input state. It will be.

  Thus, when the foreign matter 91 mixed in the crushing object 90 to be transferred is detected by the foreign matter detection unit 50, the control unit 40 normally puts the switching damper 63 when the foreign matter 91 leaves one end of the second conveyor 30. The foreign material 91 is switched to the foreign material discharge state, and the foreign material 91 falling in the guide portion 60 can be discharged toward the discharge path 61 instead of the input port 15 of the crushing device 10. As in the first embodiment, contact between the crushing device 10 and other mechanisms such as the striker and the repulsion plate and the hard foreign matter 91 prevents abnormal wear and damage to the mechanism based on the collision. It is possible to improve the durability of the consumable parts to be worn in the crushing apparatus 10, and to reduce the replacement frequency of the consumable parts, thereby improving the economy.

  In addition, while adopting a mechanism for discharging the foreign matter 91 that has reached the guide unit 60 above the crushing device 10 in this way, the arrival position of the crushing object at the crushing device inlet as shown in each of the above embodiments is changed. In the case of a system configuration that omits a mechanism for equalizing wear in each part in the crushing device, it is also possible to use only one conveyor for transferring the object to be crushed toward the crushing device. In addition, the system can be simplified by minimizing the number of conveyors used, thereby reducing costs and increasing reliability.

  Moreover, in the transfer system for crushing apparatuses according to each of the above embodiments, the first conveyor and the second conveyor are arranged for transferring the object to be crushed. However, the present invention is not limited to this. Depending on the distance from the start position to the crushing device, it is possible to arrange three or more conveyors and sequentially transfer the objects to be crushed toward the crushing device. In this case, the conveyor closest to the crushing device among the conveyors has the same configuration as the second conveyor and is operated based on the same control in the control unit, thereby discharging foreign matter as in the above embodiment. It is possible to realize equalization of wear of each part in the crushing apparatus.
