Description

A vibrator using compressed air equipped with a vibration sensor that detects vibration

[0001] The present invention relates to a vibrator using compressed air equipped with a vibration sensor that detects vibration, and more particularly, to a vibrator that efficiently detects whether the vibrator is operating by means of a vibration sensor.

[0002] Typically, vibrators are used to stir powder, transport parts consistently, or discharge scrap from press molds. These vibrators generate vibrations through the constant reciprocating motion of a piston, which is then transmitted to the stirring device, transport device, or scrap discharge device of the mold.

[0003] Recently, vibrators using compressed air have been widely used, which are structured to install a reciprocating piston inside a cylinder, inject compressed air so that it flows inside the cylinder and the piston, and cause the piston to reciprocate due to the pressure difference.

[0004] In particular, many vibrators are used in industrial sites to solve the problem of pipeline blockage during the transport and processing of powders, such as hoppers, pipes, etc.

[0005] Such technology related to the vibrator has been proposed in Korean Patent No. 1025504, which was previously registered by the applicant.

[0006] However, in Patent Document 1, in order to prevent clogging in large pipes such as chimneys, a vibrator is installed at each set location and the pipe is struck by compressed air. However, in order to distinguish between vibrators that are operating normally and those that are installed and operating but not functioning, each must be checked and inspected, and the process of checking and confirming the normal operation of the vibrator, which is repeated every day, is currently experiencing many difficulties in industrial sites, so a solution to this is required.

[0007] In particular, there is a need for a vibrator sensor that can determine the normal and abnormal operation of a vibrator installed in an invisible part, perform the function of preventing blockage of powder pipes, and check whether a vibrator is operating normally in various processes in industrial sites. Therefore, through research and development, there is a need to create a vibration sensor that detects vibration and solve the difficulties in industrial sites.

[0011] The present invention has been devised to solve the above-mentioned problems, and its purpose is to provide a vibrator using compressed air equipped with a vibration sensor that detects vibrations that can efficiently confirm whether each vibration generating unit is operating normally through sensing by the vibration sensor.

[0012] In order to achieve the above object, the vibrator using compressed air having a vibration sensor for detecting vibration of the present invention may be characterized by including: a fixed part fixed to a powder supply means at each set position; a vibration generating part movably connected to the fixed part and driving by compressed air to apply vibration as an impact to the powder supply means; and a vibration sensor for detecting vibration of the vibration generating part.

[0014] The above-mentioned fixed part and vibration generating part may be characterized as being of a piston type or a turbine type.

[0015] The vibration sensor may be characterized in that it can recognize at least one of the following states: a top-of-the-line (new product) state, a normal operating state, an abnormal operating state including a stopped state, or a state in which replacement time has arrived, depending on the color of the light being irradiated.

[0016] The above vibration sensor may be characterized in that it is powered by any one of a wire method, a power generation method, and a battery method.

[0017] The above vibration sensor may be characterized in that it outputs a signal by a wired or wireless method, and receives the output signal at a receiver and monitors it.

[0026] The above-described objects, features, and other advantages of the present invention will become more apparent by describing preferred embodiments of the present invention in detail with reference to the accompanying drawings. Hereinafter, a vibrator using compressed air equipped with a vibration sensor for detecting vibration according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0027] Referring to FIGS. 1 to 6, a vibrator (100) using compressed air having a vibration sensor for detecting vibration according to the first embodiment of the present invention is installed at each set position in the powder supply means (10) and is a device that applies vibration as an impact to the powder supply means (10) and senses the applied vibration.

[0028] At this time, the powder supply means (10) is applied to a hopper, a pipe, an elbow pipe, etc.

[0029] Here, a vibrator (100) using compressed air equipped with a vibration sensor for detecting vibration according to the first embodiment of the present invention includes a fixed part (110), a vibration generating part (120), a noise reducing part (130), a fixed part (140), and a vibration sensor (150).

[0030] Meanwhile, in the configuration of the vibrator (100) using compressed air and equipped with a vibration sensor for detecting vibration in this embodiment, a piston-type vibrator that moves the vibration generating unit (120) back and forth using compressed air is applied to the fixed unit (110) and the vibration generating unit (120), and in addition, an air vibrator or an air knocker may be applied. In this way, the fixed unit (110) functions as a piston, and the vibration generating unit (120) functions as a cylinder.

[0031] In particular, any method other than the piston method can be applied as long as it moves the vibration generating part (120) back and forth from the fixed part (110) using compressed air.

[0032] The fixed part (110) is positioned within the path of the vibration generating part (120) as shown in FIGS. 1 to 6, and a piston rod extended from the inside of the vibration generating part (120) is fixed to the powder supply means (10) so that vibration is applied to the powder supply means (10) by the impact caused by the movement of the vibration generating part (120).

[0033] At this time, the fixed part (110) is formed with a pressure slide part (112) having a relatively large diameter at the rear end of the load part (111) having a certain length, and an air guide hole (115) having an air inlet hole (113) through which air is introduced and an air discharge hole (114) through which air is discharged is formed at a certain section so that the rear end is open, and an air chamber (116) into which air is introduced and compressed is formed at the center of the end of the pressure slide part (112) so as to be in communication with the air guide hole (115).

[0034] And the positions of the air inlet holes (113) and the air discharge holes (114) formed in the fixed part (110) are formed so that, when the pressurized slide part (112) is located at the rear end of the pressurized slide guide hole (1211) of the vibration generating part (120), the air inlet holes (113) and the air discharge holes (114) are each connected to at least one air guide hole (115) on the rod part (111) before entering the rod guide hole (1231) of the cylinder head (1230). And the number of the air inlet holes (113) and the air discharge holes (114) is formed in a radial shape centered on the air guide hole (115) so that the air can be smoothly introduced and discharged even when the vibration generating part (120) is rotated while being moved back and forth.

[0035] In addition, the fixed part (110) is coupled to the cylinder head (1230) by the load part (111), and a screw part (127) is formed at the tip of the load part (111) so that it can be detachably coupled to the fixed part (140) fixed to the set position of the powder supply means (10).

[0036] As shown in FIGS. 1 to 6, the vibration generating unit (120) has a cylinder head (1230) having a pressurized slide guide hole (1211) sealed at the rear end so that the pressurized slide part (112) of the fixed part (110) is inserted and slides therein, and a rod guide hole (1231) formed through the cylinder head so that the rod part (111) of the fixed part (110) is inserted and slides therein, and is sealed at the front end.

[0037] And, in the pressurized slide guide hole (1211), an air inlet hole (1212) for introducing air is formed to be in communication with the outside, and in the load guide hole (1231), an air discharge hole (1232) for discharging air is formed to be in communication with the outside, and an air discharge guide hole (1132') for guiding air to the air discharge hole (1232) is formed around the inner surface of the load guide hole (1231) that is aligned with the air discharge hole (1232).

[0038] At this time, in this embodiment, the fixed part (110) does not generate vibration while moving forward and backward, but the vibration generating part (120) itself moves forward and backward along the fixed part (110) to generate impact force at the point where impact is required.

[0039] Moreover, the vibration generating unit (120) is composed of a cylinder housing (1210), a cylinder rear cap (1220), and a cylinder head (1230).

[0040] The cylinder housing (1210) has a pressurized slide guide hole (1211) formed longitudinally to allow the pressurized slide part (112) of the fixed part (110) to slide and be connected thereto, and an air inlet hole (1212) formed to allow air to flow into the pressurized slide guide hole (1211) is formed to communicate with the outside.

[0041] And the position of the air inlet hole (1212) formed in the cylinder housing (1210) is such that when the pressurized slide part (112) of the fixed part (110) is located at the rear end of the pressurized slide guide hole (1211) of the vibration generating part (120), the air flows into the air chamber (116) along the air inlet hole (113) and the air guide hole (115) of the fixed part (110) and is compressed, thereby easily pushing the rear end of the pressurized slide part (112) and transporting it in the forward direction, and at the same time, when the air inlet hole (113) and the air discharge hole (114) formed in the load part (111) of the fixed part (110) that have been transported in the forward direction enter the load guide hole (1231) of the cylinder head (1230), the air is formed at a position that is easy to push the front end of the pressurized slide part (112) of the fixed part (110) and transport it in the backward direction. It is desirable.

[0042] The cylinder rear cap (1220) is coupled to the rear end of the cylinder housing (1210) and seals the rear end inlet of the pressurized slide guide hole (1211).

[0043] The cylinder head (1230) is coupled to the front end of the cylinder housing (1210) to seal the front end of the pressurized slide guide hole (1211), and a rod guide hole (1231) is formed therethrough to allow the rod part (111) of the fixed part (110) to be slidably coupled thereto, and an air exhaust hole (1232) for exhausting air is formed therethrough to communicate with the outside in the rod guide hole (1231), and an air exhaust guide hole (1132') is formed around the inner circumference of the rod guide hole (1231) that is aligned with the air exhaust hole (1232) to guide air exhausted from the air exhaust hole (114) of the fixed part (110) to the air exhaust hole (1232).

[0044] Furthermore, the position of the air exhaust hole (1232) formed in the cylinder head (1230) is preferably formed at a position that matches the air inlet hole (113) and air exhaust hole (114) of the fixed part (110) that are transported forward so that the air transported forward through the fixed part (110) can be quickly discharged to the outside through the air guide hole (115) and the air exhaust hole (114) when the pressurized slide part (112) of the fixed part (110) is located at the rear end of the pressurized slide guide hole (1211) of the vibration generating part (120).

[0045] In this way, it is preferable that the vibration generating unit (120) be manufactured separately from the cylinder housing (1210), the cylinder rear cap (1220), and the cylinder head (1230) so that it can be easily disassembled and assembled. In some cases, the cylinder housing (1210) and the cylinder rear cap (1220) may be formed integrally, or the cylinder housing (1210) and the cylinder head (1230) may be formed integrally.

[0046] In addition, the coupling of the cylinder housing (1210) and the cylinder rear cap (1220) of the vibration generating unit (120) is such that a screw hole (1213) is formed in the peripheral part of the rear end of the cylinder housing (1210), a coupling hole is formed through the peripheral part of the cylinder rear cap (1220) that matches the screw hole (1213), and a bolt is fastened to the matching screw hole (1213) and the coupling hole, thereby coupling the cylinder housing (1210) and the cylinder rear cap (1220).

[0047] As shown in Fig. 3, when the pressurized slide part (112) of the fixed part (110) is positioned at the rear end of the pressurized slide guide hole (1211) of the vibration generating part (120), and the air inlet hole (113) of the fixed part (110) is exposed at the load guide hole (1231), and air of a certain pressure flows into the pressurized slide guide hole (1111) of the vibration generating part (120) through the air inlet hole (1112) of the vibration generating part (120), the air flows into the air chamber (116) through the air inlet hole (113) and the air guide hole (115) of the fixed part (110), and the air flowing into the air chamber (116) pushes the rear end of the air chamber (116) and the rear end of the pressurized slide part (112), so that the vibration generating part (120) moves in the opposite direction of the powder supply means (10). Make it move.

[0048] Afterwards, when the air discharge hole (114) formed in the load part (111) of the above-described advancing fixed part (110) enters the load guide hole (1231) of the vibration generating part (120), and the air discharge hole (114) of the fixed part (110) and the air discharge hole (1232) of the vibration generating part (120) are aligned as shown in FIG. 4, the air pushing the vibration generating part (120) is discharged through the air guide hole (115) and the air discharge hole (114) to the air discharge hole (1232) of the vibration generating part (120), and the movement of the vibration generating part (120), which was moving in the opposite direction of the powder supply means (10), is stopped.

[0049] Afterwards, when the tip of the pressurized slide part (112) of the fixed part (110) is positioned in the pressurized slide guide hole (1211) of the vibration generating part (120), and the air inlet hole (113) of the fixed part (110) enters the load guide hole (1231), the air that has entered the pressurized slide guide hole (1211) through the air inlet hole (1212) of the vibration generating part (120) cannot escape to the outside of the vibration generating part (120) because the air inlet hole (113) of the fixed part (110) enters the load guide hole (1231) of the vibration generating part (120), thereby pushing the tip of the pressurized slide part (112), causing the vibration generating part (120) to move in the direction of the powder supply means (10) as shown in FIG. 3.

[0050] The noise reduction unit (130) is provided to reduce noise caused by impact when the vibration generating unit (120) reciprocates by being coupled to the piston rod of the fixed unit (110) as shown in FIGS. 1, 2, 5, and 6.

[0051] At this time, the noise reduction part (130) can be made of silicone, rubber, urethane, plastic, wood, etc., and any other material that can reduce impact and noise can be applied.

[0052] The fixed part (140) is fixed by welding or the like to the set position of the powder supply means (10) provided at the end as shown in FIGS. 1, 2, 5 and 6, and the screw part (117) of the piston rod is threadedly fastened to the center.

[0053] Moreover, the fixed part (140) can be fixed to the powder supply means (10) by fixing the cover plate (142) to the front as shown in Fig. 6.

[0054] The vibration sensor (150) is fixed to any one of the rear, outer surface, or cover plate (142) of the vibration generating unit (120) as shown in FIGS. 1, 2, 5, and 6.

[0055] Furthermore, although not shown in the drawing, the vibration sensor can be configured by forming a groove on the outer surface of the vibration generating part, inserting it into the groove, and then covering it with a cover.

[0056] Here, the vibration sensor uses a semiconductor chip that can detect X-axis, Y-axis, and Z-axis movements to detect vibrations generated by reciprocating motion using compressed air, and configures a vibration sensor circuit, recognizes the vibration frequency generated per minute, converts the generated vibration frequency into data, and determines the frequency generated in case of normal operation as a normal frequency, and determines the frequency generated in case of abnormal operation as an abnormal frequency, and compares the data of the vibration frequency in a normal state and the abnormal vibration frequency to determine pass / fail. In particular, after comparing and determining normal operation and abnormal operation, an abnormal signal is output in case of abnormal operation to use a warning light, bell, or separate alarm, so that an abnormal phenomenon of the vibrator can be easily discovered.

[0057] For example, a vibration sensor can be applied to this, such as an acceleration sensor that measures the acceleration of vibration and counts the number of vibrations according to changes in acceleration.

[0058] Here, the acceleration sensor refers to a sensor that can measure acceleration (the rate of change in speed over time), and can obtain acceleration for changes in rotation angle based on the three axes (X, Y, Z). In other words, the sensor has the function of outputting acceleration in the direction of rotation as an analog value.

[0059] Meanwhile, when the vibration sensor (150) is installed at the rear of the vibration generating unit (120), it is located inside the cover (152) fixed to the rear of the vibration generating unit (120) (see FIG. 2).

[0060] And the cover (152) can check the LED (150a) light of the vibration sensor through the opened hole. That is, the color of the light emitted is different in the case of normal operation in which the vibration generating unit (120) moves back and forth and in the case of abnormal operation in which the vibration generating unit (120) does not move back and forth. For example, when the vibrator is in the best (best condition or new product) state, a blue light is lit, when the vibration generating unit (120) is in normal operation in which the vibration generating unit (120) moves back and forth, a green light is lit, when the vibration generating unit (120) is in an abnormal operation including a stationary state in which the vibration generating unit (120) does not move back and forth, a red light is lit, and when the vibration force is weakened and it is time to replace the vibrator (100), a yellow (yellow) light is lit, and a signal is output differently according to the light color.

[0061] At this time, different vibration frequencies are generated depending on the state of the highest level, normal operation state, abnormal operation state, and replacement period.

[0062] First, the normal state is a state in which the vibration frequency value is output to be high because there is no wear inside the vibrator (100), the normal operating state is a state in which the vibration frequency value is lower than the normal operating state but the normal value is output, the state in which the replacement time has arrived is a state in which the vibration frequency has become much weaker as it has become lower than the lower limit of the normal value of the vibration frequency of the normal operating state, and the abnormal operating state is a state in which the vibration frequency value is lower than the state in which the replacement time has arrived, and it operates but the vibration frequency does not come out, or the operation has stopped, or it operates little by little but the vibration frequency is weak.

[0063] In particular, abnormal operating conditions include situations where the machine is operating but the vibration frequency is not detected when visually confirmed, from situations where only vibration occurs in place to situations where operation has stopped.

[0064] Accordingly, the LED (150a) of the vibration sensor is blue when the vibrator (100) is in its normal state, green when the normal operating state is up to the lower limit of the normal value of the vibration frequency, yellow when the replacement period has arrived when the vibration frequency value is barely maintaining the lower limit due to wear, and red when the vibration sensor is in an abnormal operating state where it moves slightly but the vibration frequency value does not appear or stops.

[0065] Meanwhile, the measured vibration frequency is compared with a preset standard in the comparison judgment unit (not shown in the drawing) of the control unit to determine the condition of the vibrator (such as the highest condition, normal operation condition, abnormal operation condition, and replacement period).

[0066] At this time, the comparison judgment unit compares the input detection value of the vibration sensor (150) with the reference value and determines that it is in one of the following states: the highest state, normal operation state, abnormal operation state, and replacement period arrival state, and then controls the LED (150a) to output the corresponding color.

[0067] And when the vibration sensor (150) is installed on the outer surface of the vibration generating unit (120), it is fixed using a band (B) or the like (see Fig. 5).

[0068] In addition, when the vibration sensor (150) is installed on the cover plate (142), it can be fixed in a state where the length of the cover plate (142) is extended (see Fig. 6), or it can be provided in an insertion structure on one side in a state where the thickness of the cover plate (142) is increased.

[0069] Furthermore, although not shown in the drawing, the vibration sensor (150) outputs a signal by a wired or wireless signal line, and the output signal is received by the receiver and monitored.

[0070] That is, in the case of a wireless method, a sub-controller is installed for each vibration sensor (150) and each signal of the sub-controller is transmitted to the main controller.

[0071] Moreover, although not shown in the drawing, the vibration sensor (150) can be powered by a wire method, a generator method, a battery method, etc. and output a signal.

[0072] A vibrator (100) using compressed air equipped with a vibration sensor for detecting vibration according to the first embodiment of the present invention detects vibrations generated through reciprocating motion of a vibration generating unit (120) using compressed air, and realizes repetitive on / off operations of vibrations generated through vibration motion, etc., by the vibration sensor (150), and after comparing and judging normal operation and abnormal operation, outputs an abnormal signal when the operation is abnormal, so that abnormal phenomena of the vibrator can be easily discovered using a warning light, a bell, or a separate alarm.

[0073] Referring to FIGS. 7 and 8, a vibrator (200) using compressed air equipped with a conductor vibration sensor for detecting vibration according to a second embodiment of the present invention includes a fixed part (210), a vibration generating part (220), a weight (230), and a vibration sensor (240). Since the vibration sensor (240) has the same structure and function as that of the previous embodiment, a detailed description thereof will be omitted.

[0074] At this time, the vibrator (100) using compressed air equipped with a vibration sensor that detects vibration in this embodiment rotates a vibration generating part (220) that is a vibrating weight (the center of rotation of the weight is tilted to one side) using compressed air, and a turbine-type vibrator is applied to this, and in addition, a ball vibrator or the like can be applied to this.

[0075] As shown in FIGS. 7 and 8, the fixed part (210) has an installation groove (212) formed therein so that a vibration generating part (220) is positioned, and a supply pipe and a discharge pipe are respectively connected to one side of the installation groove (212) so that compressed air is supplied to the installation groove (212), and a finishing cover (214) is provided on the installation groove (212).

[0076] At this time, in this embodiment, the vibration generating unit (220) generates vibration by rotating inside the fixed unit (210) and applies impact to the point where impact is required.

[0077] Moreover, the fixed part (210) fixes the end to the powder supply means (10) and applies vibration to the powder supply means (10) by the impact caused by the rotation of the vibration generating part (220).

[0078] The vibration generating unit (220) is positioned within the installation groove (212) of the fixed unit (210) as illustrated in FIGS. 7 and 8, and applies vibration due to the impact caused by rotation within the fixed unit (210). In addition, the installation groove (212) is provided with a closing cover (214) that closes after the vibration generating unit (220) is coupled. Here, the symbol 242, which is not described, represents a cover.

[0079] Furthermore, the vibration generating unit (220) has compressed air blades (222) formed radially on the outer surface, so that compressed air can be supplied in the direction of the compressed air blades (222) and rotate around the axis.

[0080] As shown in Fig. 8, a plurality of weights (230) are fixed to one side of the inner diameter of the vibration generating unit (220) to cause a tilting phenomenon when the vibration generating unit (220) rotates, thereby causing the center of gravity to shift and generating vibration in the vibration generating unit (220).

[0081] Referring to FIG. 7, the vibration sensor (240) is installed on the outer surface of the vibration generating unit (220), i.e., the outer surface of the finishing cover (214), as in the previous embodiment, but the installation location is not limited thereto and can be changed.

[0082] Furthermore, although not shown in the drawing, the vibration sensor (240) outputs a signal by a wired or wireless signal line, and the output signal is received by the receiver and monitored.

[0083] That is, a sub-controller is installed for each vibration sensor (240) and each signal of the sub-controller is transmitted to the main controller.

[0084] Moreover, although not shown in the drawing, the vibration sensor (240) can be powered by a wire method, a generator method, a battery method, etc. and output a signal.

[0085] A vibrator (200) using compressed air equipped with a vibration sensor for detecting vibration according to the second embodiment of the present invention detects vibrations generated through the rotational movement of a vibration generating unit (220) using compressed air, and the vibration generated through the on / off repetitive operation is realized by detecting the vibrations, etc., by the vibration sensor (240), and after comparing and judging normal operation and abnormal operation, an abnormal signal is output when the operation is abnormal, so that an abnormal phenomenon of the vibrator can be easily discovered using a warning light, a bell, or a separate alarm.

[0086] The configurations included in the various embodiments described above may also be implemented as embodiments of various other possible combinations of changes not exemplified above, as long as the combinations are not clearly mutually exclusive in terms of implementation.
