Description

Technical Field

[0001] This invention relates to the field of suspension conveying technology, and more specifically to a valve suspension conveying system and conveying method. Background Technology

[0002] Valve is a component of a car engine, and it is generally divided into intake valves and exhaust valves according to its use. The valve structure includes a stem and a head located at one end of the stem; similar to the suspension transport of bolts, valves are also transported between various stages of processing equipment via suspension.

[0003] The transmission belt is the core structure in suspended conveyor systems. It needs to be bent into a closed loop to achieve cyclic rotation, which requires the use of elastic rubber materials.

[0004] The drive belt needs to support the valve head upwards to generate compression, friction, and support forces (to enable valve suspension and movement). Therefore, the groove structure accommodating the drive belt must be open upwards. However, this leads to the accumulation of metal debris (such as cutting debris adsorbed on the valve surface by electrostatic attraction or the viscosity of cutting fluid; and cutting debris is usually angular and sharper) and cutting fluid (which adheres to the valve, then to the drive belt, and then accumulates in the groove structure) in the groove structure. As a result, the drive belt (to drive the valve) is easily scratched by metal debris during movement, which shortens the service life of the drive belt (to drive the valve in a straight line, the drive belt needs to be taut to make part of it straight; once a taut drive belt is scratched and a gap appears, the gap will expand rapidly under the tension, causing the drive belt to break). Summary of the Invention

[0005] In order to overcome the problem of "the transmission belt being scratched when driving the valve" in the above-mentioned background art, the present invention provides a valve suspension delivery system and delivery method.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A valve suspension delivery system includes a suspension traverse module comprising several belt conveyor segments; each belt conveyor segment includes a first track, a second track, and a drive belt; a suspension groove is provided between the first track and the second track; the drive belt is vertically disposed beside the suspension groove and slidably connected to the second track; the valve stem is inserted into the suspension groove, and when the valve head is pressed against the top surface of the drive belt, the drive belt can drive the valve to move; the second track has a guide groove, and the drive belt is fitted and engaged in the guide groove; the guide groove includes... The upper straight groove; the second track has a side recessed hole on the side wall facing the suspension groove, and the side recessed hole has a first side wall; the second track has an inclined drain hole; the top opening of the drain hole is located at the bottom end of the upper straight groove, and the bottom opening of the drain hole is located at the first side wall; a door panel is hinged to the first side wall to control the opening and closing of the bottom opening of the drain hole; when the valve travels along the suspension groove, it can push the end of the door panel and open the door panel, so that the inner cavity of the drain hole generates negative pressure to draw in the mixture of metal shavings and cutting fluid in the upper straight groove.

[0008] As a further optimization of the present invention, a torsion spring is provided at the hinge position of the first sidewall and the door panel. The torsion spring is used to drive the door panel to rotate to fit against the first sidewall in order to seal the bottom opening of the leakage hole.

[0009] As a further optimization of the present invention, the surface of the first sidewall is provided with an elastic sealing layer.

[0010] As a further optimization of the present invention, when the door panel is attached to the first side wall, the end of the door panel away from the torsion spring is inserted into the suspension groove; the first side wall is arranged perpendicular to the suspension groove.

[0011] As a further optimization of the present invention, the bottom end of the side recessed hole is provided with an inclined bottom surface; the inclined bottom surface is inclined downward at the end near the suspension groove.

[0012] As a further optimization of the present invention, the first track and the second track are arranged parallel to each other; the upper straight groove is arranged along the length direction of the second track.

[0013] As a further optimization of the present invention, the belt conveyor segment further includes a driving wheel, a driven wheel, and a first motor; one end of the transmission belt is configured to cover the groove of the driving wheel, and the other end is configured to cover the groove of the driven wheel; the driving wheel and the driven wheel are respectively located at both ends of the second track; the first motor is connected to the driving wheel.

[0014] As a further optimization of the present invention, a control module for driving the intermittent delivery of the valve is also included.

[0015] As a further optimization of the present invention, it also includes a loading module and a unloading module disposed at the end of the suspension transverse module.

[0016] A valve suspension delivery method is provided, wherein the valve suspension delivery system is used to intermittently deliver the valve, and the delivery speed of the valve is adapted to the processing speed of the machine tool.

[0017] In summary, the present invention has at least one of the following advantages:

[0018] (1) The present invention has a simple structure and reliable function. When the valve moves along the suspension groove, it can push the end of the door panel and open the door panel, so that the cavity inside the leakage hole generates an instantaneous negative pressure. Under the drive of the negative pressure and combined with its own gravity, the mixed fluid can more easily leak downward, thereby removing metal debris and cutting fluid from the upper straight groove, thus avoiding the problem of the transmission belt being scratched by metal debris. At the same time, the present invention realizes the automation of metal debris and cutting fluid removal without manual operation.

[0019] (2) The bottom ends of the second track and the transmission belt are both inclined away from the first track, so that the second track and the suspension groove form a triangular groove. Water guide fins are provided on the side wall of the second track near the suspension groove, and the top surface of the water guide fins is coplanar with the inclined bottom surface. The mixed fluid flows along the inclined bottom surface to the water guide fins and then drips down through the triangular groove. It will not flow down along the side wall of the second track (to avoid the mixed fluid from adhering to the transmission belt below) nor will it adhere to the valve stem. This achieves rapid removal of the mixed fluid and avoids the problem of the mixed fluid accumulating more and more on the belt conveyor segment.

[0020] (3) The first track and the second track are connected by an n-shaped plate; the user can use two adjusting nuts to clamp the end of the n-shaped plate at different positions of the cross brace, thereby adjusting the width of the suspension groove, so as to transport valves with different rod diameters, thereby improving the convenience of operation.

[0021] (4) The first and second insert rods are used to block the valves that are stacked continuously, and control the valves to continue to move one by one in an intermittent manner to match the processing speed of the machine tool and the lifting speed of the lifting module.

[0022] (5) After the valve slides out from the belt conveyor segment, it slides further along the fan-shaped vertical plate, and the valve that was originally set vertically is changed to be set horizontally. The valve set horizontally has a column head with a fixed horizontal position, which makes it easier to be engaged and clamped by the horizontally set feeding module.

[0023] (6) When the clamping plate is placed at the bottom of the fan-shaped plate, the opening of the adapter slot faces upward to accommodate the sliding valve; the rotating plate can rotate 180 degrees, so that when the valve is inserted into the grinding gap, the opening of the adapter slot is in the downward state, and the valve moves downward and passes through the grinding gap while being dislodged from the adapter slot, realizing the convenient separation of the feeding module and the valve, improving work efficiency and simplifying the mechanical structure.

[0058] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0059] Reference Figures 1-2 This embodiment provides a valve 6 suspension conveying system, including a suspension lateral movement module 1, which includes several belt conveyor segments 11; the several belt conveyor segments 11 are connected in series to form the suspension lateral movement module 1, which is used for the lateral conveying of valve 6 between different machine tools 5.

[0060] Reference Figures 2-4The belt conveyor segment 11 includes a first track 111, a second track 112, and a drive belt 113; a suspension groove 1110 is provided between the first track 111 and the second track 112; the first track 111 and the second track 112 are arranged parallel to each other, thereby forming a suspension groove 1110 with a constant width, which prevents the valve 6 from getting stuck in the narrow part of the suspension groove 1110, or the valve 6 from coming off downward in the wide part of the suspension groove 1110.

[0061] Reference Figure 2 and Figure 3 The transmission belt 113 is vertically positioned beside the suspension groove 1110 and slidably connected to the second track 112. The valve 6 includes a rod portion 62 and a post head 61 fixedly mounted at one end of the rod portion 62 (e.g., by an integral fixed connection). Under the weight of the valve 6 itself, the rod portion 62 can be vertically inserted into the suspension groove 1110, and a portion of the bottom surface of the post head 61 presses against the top surface of the first track 111 and a portion presses against the top surface of the transmission belt 113, thereby suspending the valve 6. When the rod portion 62 is inserted into the suspension groove 1110 and the post head 61 presses against the top surface of the transmission belt 113, the transmission belt 113 can (move to transmit frictional force to the post head 61 and) drive the valve 6 forward, thereby achieving lateral delivery of the valve 6.

[0062] Reference Figure 3 and Figure 4 The second track 112 is provided with a guide groove 1120. The transmission belt 113 is adapted to be engaged in the guide groove 1120 and slides along the guide groove 1120. The guide groove 1120 includes an upper straight groove 11201 and a lower straight groove located below the upper straight groove 11201. The opening of the upper straight groove 11201 faces upward to engage the upper straight portion of the transmission belt 113, and the opening of the lower straight groove faces downward to engage the lower straight portion of the transmission belt 113. The upper straight groove 11201 and the lower straight groove are arranged parallel to each other. Under its own gravity, metal chips and / or cutting fluid will accumulate in the upper straight groove 11201.

[0063] Reference Figure 2 , Figure 3 and Figure 5The belt conveyor segment 11 also includes a drive pulley 114, a driven pulley 115, and a first motor 116. The drive pulley 114 has an annular groove on its circumference, and the driven pulley 115 also has an annular groove on its circumference. One end of the transmission belt 113 covers the groove of the drive pulley 114, and the other end covers the groove of the driven pulley 115. The drive pulley 114 and the driven pulley 115 are respectively located at both ends of the second track 112 and are adapted to the upper straight groove 11201 and the lower straight groove. When the drive pulley 114 rotates, it can drive the transmission belt 113 to move, thereby driving the driven pulley 115 to rotate. The first motor 116 is connected to the drive pulley 114. The housing of the first motor 116 is fixedly connected to the side wall of the second track 112 away from the suspension groove 1110 (e.g., by bolts). The first output shaft of the first motor 116 is inserted into and fixedly connected to the center position of the drive wheel 114 (e.g., by bolts). The first motor 116 can drive the drive wheel 114 to rotate. The driven wheel 115 is rotatably connected to the second track 112 (e.g., by bearings and a shaft).

[0064] Reference Figure 4 and Figure 6 The second track 112 has a side recess 1121 on its side wall facing the suspension groove 1110, and the side recess 1121 communicates with the suspension groove 1110. The end of the side recess 1121 away from the suspension groove 1110 has a blind hole structure, and the side recess 1121 has a first side wall 11212. The second track 112 has an inclined drain hole 1122. The top opening of the drain hole 1122 is located at the bottom end of the upper straight groove 11201, and the bottom opening of the drain hole 1122 is located at the first side wall 11212. The top of the drain hole 1122 communicates with the upper straight groove 11201, and the bottom end communicates with the side recess 1121. A door panel 1123 that can control the opening and closing of the bottom opening of the drain hole 1122 is hinged to the first side wall 11212. When the door panel 1123 rotates to fit and conform to the first side wall 11212, it can seal the bottom opening of the leak hole 1122 (i.e., close the bottom opening of the leak hole 1122), and at this time, the bottom opening of the leak hole 1122 will show a state of increased air pressure (i.e., positive air pressure) for a short period of time; when the door panel 1123 rotates to disengage from the first side wall 11212, it can open the bottom opening of the leak hole 1122, and at this time, the bottom opening of the leak hole 1122 will show a state of decreased air pressure (i.e., negative air pressure) for a short period of time.

[0065] Reference Figure 4 , Figure 6 and Figure 7When valve 6 advances along the suspension groove 1110, it pushes the end of the door plate 1123 and opens the door plate 1123, creating a negative pressure in the cavity of the drain hole 1122 to draw in the mixed fluid containing metal shavings and cutting fluid from the upper straight groove 11201. Afterwards, the door plate 1123 closes, and the mixed fluid accumulates at the bottom of the drain hole 1122. When the next valve 6 advances along the suspension groove 1110, it pushes the end of the door plate 1123 again and opens the door plate 1123, creating a negative pressure in the cavity of the drain hole 1122 again. The mixed fluid flows out from the bottom of the drain hole 1122 (flowing into the side recess 1121, and then continuing to flow downwards along the inclined bottom surface 11211 until it flows out from the side recess 1121), while the mixed fluid in the upper straight groove 11201 is drawn into the drain hole 1122, thus achieving circulation.

[0066] A torsion spring is provided at the hinge position of the first side wall 11212 and the door panel 1123. The torsion spring is used to drive the door panel 1123 to rotate to fit against the first side wall 11212, so as to seal the bottom opening of the leakage hole 1122. That is, after the valve 6 passes the side recess 1121, the torsion spring drives the door panel 1123 to close automatically.

[0067] The first sidewall 11212 has an elastic sealing layer (e.g., a rubber layer) on its surface, so when the door panel 1123 is attached to the first sidewall 11212, the two have a higher sealing performance.

[0068] Some metal debris may adhere to the first sidewall 11212 / elastic sealing layer, causing a gap between the door and the first sidewall 11212 that cannot be sealed. However, vibrations are generated when the valve 6 travels along the suspension groove 1110, when the valve 6 impacts the door panel 1123, and when the door panel 1123 closes under the drive of the torsion spring (i.e., when it impacts the first sidewall 11212 / elastic sealing layer). These vibrations are transmitted to the second track 112, so the metal debris will slide down the first sidewall 11212 / elastic sealing layer under the action of vibration until it slides to the inclined bottom surface 11211, where it will no longer obstruct the sealing fit between the door panel 1123 and the first sidewall 11212 / elastic sealing layer. After the sealing fit between the door panel 1123 and the first sidewall 11212 / elastic sealing layer is restored, the next time the valve 6 opens the door, a negative pressure will be generated again in the leakage hole 1122, thereby drawing in the mixed fluid in the upper straight groove 11201, realizing the self-repair of the present invention.

[0069] Reference Figure 7 When the door panel 1123 is in contact with the first side wall 11212, the end of the door panel 1123 away from the torsion spring is inserted into the suspension groove 1110. When the valve 6 moves along the suspension groove 1110, it can hit the end of the door panel 1123 away from the torsion spring, thereby pushing the door panel 1123 to open. The first side wall 11212 is perpendicular to the suspension groove 1110.

[0070] Reference Figure 6 and Figure 8 The bottom end of the side concave hole 1121 is provided with an inclined bottom surface 11211; the end of the inclined bottom surface 11211 near the suspension groove 1110 is inclined downward to discharge the mixed fluid from the side concave hole 1121.

[0071] Reference Figure 4 The upper straight groove 11201 is set along the length direction of the second track 112.

[0072] Reference Figure 8 The bottom ends of the second track 112 and the transmission belt 113 are both inclined away from the first track 111, forming a triangular groove 11101 (the cross-section of the triangular groove 11101 is triangular) between the second track 112 and the suspension groove 1110. Water guide fins 11213 are provided on the side wall of the second track 112 near the suspension groove 1110, with the top surface of the water guide fins 11213 coplanar with the inclined bottom surface 11211. The mixed fluid flows along the inclined bottom surface 11211 to the water guide fins 11213 and then drips down through the triangular groove 11101. It will not flow downwards along the side wall of the second track 112 (near the suspension groove 1110) (where the mixed fluid would flow further downwards until it adheres again to the transmission belt 113 below), nor will it adhere again to the valve stem 62. This achieves rapid removal of the mixed fluid and avoids the problem of the mixed fluid accumulating on the belt conveyor segment 11.

[0073] Reference Figure 9 For locations requiring curved conveying, the belt conveyor segment 11 is L-shaped, and both the first track 111 and the second track 112 are L-shaped. A rotatable steering wheel 1151 is located at a right-angle position on the second track 112. The steering wheel 1151 is horizontally positioned with its axis vertically oriented. A groove is provided on the circumference of the steering wheel 1151, and the middle portion of the transmission belt 113 is engaged within this groove to achieve the directional conveying of the valve 6. Since both the second track 112 and the steering wheel 1151 need to be positioned inside the turning direction, when assembling this invention, simply swapping the positions of the first track 111 and the second track 112 allows for leftward or rightward turning.

[0074] Reference Figure 1 and Figure 2 The suspended transverse module 1 also includes a column 12 for supporting the belt conveyor segment 11. The bottom end of the column 12 is fixedly installed on the floor of the processing workshop (e.g., by bolts). The middle or top of the column 12 is fixedly connected to the side wall of the first track 111 (away from the second track 112) (e.g., by bolts).

[0075] Reference Figure 1 and Figure 10It also includes a control module 2 for intermittently driving valve 6. The control module 2 includes several material separation components 21 and several sensing sensors 22 (e.g., eddy current distance sensors or laser distance sensors). The sensing sensors 22 are fixedly connected to the first track 111 / second track 112 by bolts.

[0076] The material separation assembly 21 is provided with several components, namely, the first material feeding separation assembly 21a, the second material feeding separation assembly 21b, the second material conveying separation assembly 21c, the second material feeding separation assembly 21d, the third material feeding separation assembly 21e, and the third material conveying separation assembly 21f.

[0077] The sensing sensor 22 is provided with several sensors, namely, the first feeding full sensor 22a, the first feeding material sensor 22b, the second feeding full sensor 22c, the second conveying full sensor 22d, the second conveying material sensor 22e, the second feeding full sensor 22f, the second feeding material sensor 22g, and the third feeding full sensor 22h.

[0078] Reference Figure 1 and Figure 10 The material separator assembly 21 includes a first insert 211 and a second insert 212, which can extend or retract independently. The first insert 211 can be laterally inserted into the suspension groove 1110 to stop the rod portion 62 of the first valve 6 at the front end. The second insert 212 can be laterally inserted into the suspension groove 1110 to stop the rod portion 62 of the second valve 6. A limiting gap is provided between the first insert 211 and the second insert 212 to accommodate the rod portion 62 of the first engaging valve 6 at the front end. The first insert 211 is located in front of the second insert 212 (with the forward direction of the valve 6 as the front side).

[0079] Reference Figure 10 The first insert rod 211 is coaxially and fixedly connected to the telescopic shaft of the first linear actuator 213. The first linear actuator 213 drives the first insert rod 211 to extend and retract. The second insert rod 212 is coaxially and fixedly connected to the telescopic shaft of the second linear actuator 214. The second linear actuator 214 drives the second insert rod 212 to extend and retract. The housing of the first linear actuator 213 is fixedly connected to the first track 111 / second track 112 by bolts; the housing of the second linear actuator 214 is also fixedly connected to the first track 111 / second track 112 by bolts. Both the first linear actuator 213 and the second linear actuator 214 are arranged laterally.

[0080] Reference Figure 10The steps for separating and discharging valves 6 include: ① The first insert rod 211 extends to stop the first valve 6, thus stopping all valves 6; ② The second insert rod 212 extends, and then the first insert rod 211 retracts, allowing the first valve 6 to continue moving forward (driven by the drive belt 113), while the remaining valves 6 remain stopped; ③ The first insert rod 211 extends, and then the second insert rod 212 retracts, allowing the remaining valves 6 (driven by the drive belt 113) to move forward one position synchronously. Therefore, the separating assembly 21 can block several valves 6 that are continuously piled together, while allowing the valves 6 to continue moving one by one in an intermittent manner.

[0081] Reference Figure 1 , Figure 16 and Figure 17 It also includes a lifting module 3 disposed between two adjacent belt conveyor segments 11 with a height difference. The lifting module 3 includes a support column 31, a suction cup 32, a horizontal telescopic arm 33, and a vertical drive assembly. The bottom of the support column 31 is fixedly installed on the floor of the processing workshop. The vertical drive assembly is a ball screw pair driven by a second motor, and the vertical drive assembly is installed in the inner cavity of the support column 31. The housing of the second motor is fixedly connected to the top of the support column 31 by bolts. The second rotating shaft of the second motor is coaxially set with the ball screw pair and fixedly connected by bolts. The second rotating shaft is used to drive the screw of the ball screw pair to rotate, thereby driving the nut of the ball screw pair to rise and fall. The nut and the slider are fixedly connected by bolts. The slider and the inner side wall of the support column 31 are slidably connected by a ball linear guide pair (to prevent the slider and nut from rotating). The horizontal telescopic arm 33 is a horizontally placed fifth linear actuator 512. The housing of the fourth linear actuator is fixedly connected to the slider by bolts. The fourth output shaft of the fourth linear actuator is fixedly connected to the suction cup 32 by bolts. The suction cup 32 is an electromagnetic suction cup 32 or a vacuum suction cup 32, which can grasp the valve 6 located below. After the suction cup 32 grabs the valve 6 located below, the vertical drive assembly drives the horizontal telescopic arm 33, the suction cup 32 and the valve 6 to rise synchronously. Then, the horizontal telescopic arm 33 drives the valve 6 and the suction cup 32 to move laterally to above the suspension groove 1110 of the belt conveyor segment 11 located above. After that, the suction cup 32 releases the valve 6, and the valve 6 falls downward and inserts into the suspension groove 1110 to achieve conveying.

[0082] Reference Figure 1 , Figure 13 and Figure 15 It also includes a feeding module 4 located at the end of the suspension transverse module 1.

[0083] Reference Figures 11-15The processing machine tool 5 has three parts, namely the first machine tool 5a, the second machine tool 5b, and the third machine tool 5c; the loading module 4 has two parts, namely the loading module a4a and the loading module b4b; the lifting module 3 has two parts, namely the first lifting module 3a and the second lifting module 3b. Therefore, the steps of the intermittent conveying valve 6 include: S1, the first unloading process; S2, the second loading process; S3, the first feeding process; S4, the second unloading process; S5, the third loading process; and S6, the second feeding process.

[0084] Reference Figure 13 When two adjacent belt conveyor segments 11 are disconnected at a bend, two vertical sliding plates 13 can be installed between them, forming a slide rail structure. The valve 6 can slide downwards along the slide rail, achieving a transition between the two belt conveyor segments 11. The vertical sliding plates 13 are bolted to the top of the column, and the bottom of the column is bolted to the floor of the processing workshop, providing support for the vertical sliding plates 13.

[0085] Reference Figure 18 and Figure 19 The feeding module 4 includes a support horizontal plate 41, a fan-shaped vertical plate 42, a rotating plate 43, a clamping vertical plate 44, and a pressing block 45. The fan-shaped vertical plates 42 are arranged in pairs, and an arc-shaped groove 420 is provided between the two fan-shaped vertical plates 42. The fan-shaped vertical plates 42 are fixedly installed on one end of the support horizontal plate 41 (for example, by means of a support rod 421, the top and bottom ends of the support rod 421 are respectively fixedly connected to the fan-shaped vertical plate 42 and the support horizontal plate 41 by bolts). The belt conveyor segment 11, the fan-shaped vertical plates 42 and the support horizontal plate 41 are arranged in a Z-shape. The suspension groove 1110 of the belt conveyor segment 11 is adapted and aligned with the top end of the arc-shaped groove 420, so as to be used for the transition movement of the valve 6. One end of the rotating plate 43 is hinged to the end of the support horizontal plate 41 (away from the fan-shaped vertical plate 42), and the other end can rotate to the bottom end of the arc-shaped groove 420 to receive the valve 6 (slid down through the arc-shaped groove 420). The valve 6 can slide along the arc surface of the top surface of the fan-shaped vertical plate 42; when the valve 6 slides on the fan-shaped vertical plate 42, the rod part 62 is inserted into the arc groove 420 and the column head 61 is pressed against the arc surface of the top surface of the fan-shaped vertical plate 42.

[0086] Reference Figure 18 and Figure 19A locking plate 44 is provided at the end of the rotating plate 43 near the fan-shaped vertical plate 42. The locking plate 44 is vertically fixed to the rotating plate 43 (e.g., by an integral fixed connection). A matching groove 441 is provided in the middle of the edge of the locking plate 44 away from the rotating plate 43. A pressing block 45 that can move laterally is provided on the side of the locking plate 44. The pressing block 45 and the locking plate 44 are located on the same side of the rotating plate 43. A clamping groove 440 is provided between the pressing block 45 and the locking plate 44. The valve 6, which was originally vertically arranged, is horizontally arranged after sliding past the fan-shaped vertical plate 42 and can lock the end of the rod 62 near the column head 61 into the matching groove 441, and the column head 61 is locked in the clamping groove 440; then the pressing block 45 can move towards the locking plate 44 to clamp the valve 6.

[0087] Reference Figure 18 and Figure 19 The pressing block 45 is connected to the third linear actuator 451. The housing of the third linear actuator is fixedly connected to the rotating plate 43 by bolts. The third output shaft of the third linear actuator is fixedly connected to the pressing block 45 by bolts. The third linear actuator is used to drive the pressing block 45 to move closer to or further away from the clamping plate 44.

[0088] Reference Figures 18-20 After the valve 6 is clamped by the clamping plate 44 and the pressing block 45, the rotating plate 43 can rotate, thereby placing the valve 6 into the machining tool 5. The machining tool 5 is a centerless grinder.

[0089] Reference Figure 20 , Figure 21 and Figure 22 The centerless grinder includes a machine housing 51 and grinding rollers 52 disposed in the inner cavity of the machine housing 51. A third motor connected to the grinding rollers 52 is provided in the inner cavity of the machine housing 51. The third motor is used to drive the grinding rollers 52 to rotate. The grinding rollers 52 are arranged in pairs, and a grinding gap 520 is provided between the two pairs of grinding rollers 52. During the process of the valve 6 rod 62 passing through the grinding gap 520 (at this time, the axis of the valve 6 is parallel to the axis of the grinding roller 52), the grinding process is achieved by the friction of the grinding roller 52.

[0090] Reference Figure 22An inverted fourth linear actuator is positioned above the grinding gap 520. The housing of the fourth linear actuator is bolted to the machine tool housing 51. A replaceable wear-resistant head 5121 is bolted to the bottom end of the fourth output shaft of the fourth linear actuator. When the fourth output shaft extends, it pushes the wear-resistant head 5121 downward to press against the rod 62 of the valve 6, allowing the rod 62 of the valve 6 to pass through the grinding gap 520. A dustproof sleeve is provided around the fourth output shaft to prevent flying cutting chips from getting stuck between the housing of the fourth linear actuator and the fourth output shaft (i.e., to avoid the problem of the fourth output shaft getting stuck and difficult to retract). The top end of the dustproof sleeve is sealed and fixedly connected (e.g., bonded) to the housing of the fourth linear actuator, and the bottom end is sealed and fixedly connected (e.g., bonded) to the wear-resistant head 5121.

[0091] Reference Figure 20 and Figure 21 Each of the two edges of the bottom surface of the supporting horizontal plate 41 is provided with a side plate 46, which are arranged parallel to each other. The top of the side plate 46 is vertically and fixedly connected to the bottom surface of the supporting horizontal plate 41 (e.g., by bolts), and the bottom is vertically and fixedly connected to the bottom support horizontal plate 47 (e.g., by bolts). The bottom support horizontal plate 47 is fixedly connected to the machine tool housing 51 (e.g., by bolts), and a reinforcing angle iron 471 is welded at the connection position to achieve stable support for the feeding module 4, so that the feeding module 4 is supported on the side of the side opening 511 of the machine tool housing 51. During the rotation of the rotating plate 43, it can drive the valve 6 to pass through the side opening 511 to enter the inner cavity of the centerless grinder, thereby contacting the grinding roller 52.

[0092] Reference Figure 20 and Figure 21 It also includes a feeding module located at the end of the suspension transverse module 1. The feeding module includes two V-shaped feeding troughs 7, with a strip-shaped through groove 71 between the two feeding troughs 7. When the valve 6 is located in the feeding module, the column head 61 is pressed against the feeding trough 7, and the rod part 62 is inserted into the strip-shaped through groove 71, thereby suspending the valve 6. The end of the feeding trough 7 near the centerless grinder is inclined upward and the end near the belt conveyor section 11 is inclined downward, so that the valve 6 falling out of the centerless grinder can slide in the feeding module until it is vertically pressed against the belt conveyor section 11, thereby achieving feeding.

[0093] Reference Figure 20 and Figure 21 After valve 6 passes through the grinding gap 520, the clamping block releases valve 6, and valve 6 falls into the unloading module; then the rotating plate 43 rotates in the opposite direction to load the next valve 6.

[0094] Reference Figure 21The outer wall of the unloading trough plate 7 is fixedly connected to the inner wall of the side upright plate 46 (e.g., by bolts), thereby using the loading module 4 to support the unloading module.

[0095] Reference Figure 23 When the locking plate 44 rotates to the side of the fan-shaped plate 42, the valve 6, during its downward sliding along the fan-shaped plate 42, is prone to the problem of its head 61 hitting the top surface of the locking plate 44. This makes it difficult for the head 61 to insert into the clamping slot 440. To avoid this problem: refer to... Figure 24 The bottom of the fan-shaped vertical plate 42 is provided with a clearance notch 4200 that is adapted to the rotation radius of the locking plate 44. The locking plate 44 can rotate and be locked into the clearance notch 4200 (at this time, the adapter slot 441 is adapted to the bottom end of the arc slide groove 420), so that the column head 61 can be adapted to slide into the clamping groove 440 and the rod part 62 can be adapted to insert into the adapter slot 441, so as to realize the clamping of the valve 6 by the subsequent pressing block 45.

[0096] Reference Figure 5 The first track 111 and the second track 112 are connected by an n-shaped plate 1111. The n-shaped plate 1111 is positioned above the suspension groove 1110 to avoid obstructing the movement of the valve 6. One end of the n-shaped plate 1111 is fixedly connected to the top surface of the second track 112 (e.g., by bolts), and the other end is connected to the side wall of the first track 111 away from the second track 112. A cross brace 1113 is fixedly installed on the side wall of the first track 111 away from the second track 112, and the end of the cross brace 1113 is vertically fixedly connected to the first track 111 (e.g., by bolts or welding). The middle part of the cross brace 1113 is inserted into the horizontal hole at the end of the n-shaped plate 1111; two adjusting nuts 1112 are connected to the outer periphery of the cross brace 1113 by threads, and the two adjusting nuts 1112 clamp and limit the end of the n-shaped plate 1111 from both sides; the user can use the two adjusting nuts 1112 to clamp the end of the n-shaped plate 1111 at different positions of the cross brace 1113, thereby adjusting the width of the suspension groove 1110, which can be used to deliver valves 6 with different rod diameters 62.

[0097] A valve 6 suspension conveying method employs a valve 6 suspension conveying system to intermittently convey the valve 6, and the conveying speed of the valve 6 is adapted to the processing speed of the machine tool 5. The intermittent conveying steps of the valve 6 include: S1, first unloading step; S2, second loading step; S3, first feeding step; S4, second unloading step; S5, third loading step; S6, second feeding step. Details are as follows (in conjunction with...). Figures 11-15 ):

[0098] First material preparation process:

[0099] ① The first machine tool 5a discharges air valve 6 (when the first feeding full sensor 22a detects air valve 6, it means that the air valve 6 is full between the first feeding full sensor 22a and the first feeding material sensor 22b, then the first machine tool 5a stops feeding).

[0100] ② The valve 6 moves along the belt conveyor segment 11 to the position of the first material feeding and separating assembly 21a and stacks up together in a continuous manner.

[0101] ③ The first feeding and separating component 21a controls the (stacked) valves 6 to continue moving (towards the first feeding and material sensor 22b) one by one in an intermittent manner. (When the first feeding and material sensor 22b detects the presence of valve 6, it controls the first feeding and separating component 21a to stop feeding, thereby ensuring that there is only one valve 6 between the first feeding and separating component 21a and the first feeding and material sensor 22b at any time, thus adapting to the single lifting operation of the first lifting module 3a).

[0102] Second feeding process:

[0103] ① When the first material sensor 22b detects valve 6, the first lifting module 3a lifts valve 6 (from the lower belt conveyor segment 11) to the upper belt conveyor segment 11.

[0104] ② The valve 6 moves along the belt conveyor segment 11 to the position of the second feeding separator assembly 21b and is stacked together in a continuous manner.

[0105] ③ The second feeding and separating component 21b controls the (stacked) valves 6 to continue moving (towards the second conveying and separating component 21c) one by one in an intermittent manner. (When the second feeding full sensor 22c detects the presence of valves 6, it means that the space between the second feeding and separating component 21b and the second feeding full sensor 22c is full of valves 6, and the first lifting module 3a stops lifting the valves 6).

[0106] First feeding process:

[0107] ① The valve 6 moves along the belt conveyor segment 11 to the position of the second conveyor material separation assembly 21c and stacks together in a continuous manner.

[0108] ② The second conveying and separating component 21c controls the (stacked) valves 6 to continue moving one by one in an intermittent manner (towards the feeding module a4a). (When the second discharging and separating component 21d detects the presence of valves 6, it means that the space between the second conveying and separating component 21c and the second discharging and separating component 21d is full of valves 6, then the second feeding and separating component 21b stops discharging the valves 6).

[0109] ③ The valve 6 discharged from the second conveying and separating component 21c is fed into the second machine tool 5b via the feeding module a4a (when the second conveying material sensor 22e detects the presence of valve 6, the second conveying and separating component 21c stops discharging material, ensuring that there is at most one valve 6 between the second conveying and separating component 21c and the feeding module a4a, thereby adapting to the single feeding operation of the feeding module a4a).

[0110] Second material preparation process:

[0111] ① The second machine tool 5b discharges air valve 6 (when the second feeding full sensor 22f detects air valve 6, it means that the air valve 6 is filled between the second feeding material sensor 22g and the second feeding full sensor 22f, then the second machine tool 5b stops feeding).

[0112] ② The valve 6 moves along the belt conveyor segment 11 to the position of the second material feeding and separating assembly 21d and stacks together in a continuous manner.

[0113] ③ The second feeding and separating component 21d controls the (stacked) valves 6 to continue moving (towards the second feeding and material sensor 22g) one by one in an intermittent manner. (When the second feeding and material sensor 22g detects the presence of valve 6, it controls the second feeding and separating component 21d to stop feeding, thereby ensuring that there is only one valve 6 between the second feeding and separating component 21d and the second feeding and material sensor 22g at a time, thus adapting to the single lifting operation of the second lifting module 3b).

[0114] Third material feeding process:

[0115] ① When the second material sensor 22g detects valve 6, the second lifting module 3b lifts valve 6 (from the lower belt conveyor segment 11) to the upper belt conveyor segment 11.

[0116] ② The valve 6 moves along the belt conveyor segment 11 to the position of the third feeding separator assembly 21e and is stacked together in a continuous manner.

[0117] ③ The third feeding and separating component 21e controls the (stacked) valves 6 to continue moving (towards the third conveying and separating component 21f) one by one in an intermittent manner. (When the third feeding full sensor 22h detects the presence of valves 6, it means that the space between the third feeding and separating component 21e and the third feeding full sensor 22h is full of valves 6, and the second lifting module 3b stops lifting the valves 6).

[0118] Second feeding process:

[0119] ① The valve 6 moves along the belt conveyor segment 11 to the position of the third conveyor material separation assembly 21f and is stacked together in a continuous manner.

[0120] ② The third conveying and separating component 21f controls the (stacked) valves 6 to continue moving (towards the feeding module b4b) one by one in an intermittent manner. (When the third conveying full sensor 22j detects the presence of valves 6, it means that the space between the third conveying and separating component 21f and the third conveying full sensor 22j is full of valves 6, and the third feeding and separating component 21e stops discharging material from the valves 6).

[0121] ③ The valve 6 discharged from the third conveying and separating component 21f is fed into the third machine tool 5c via the feeding module b4b (when the third conveying material sensor 22i detects the presence of valve 6, the third conveying and separating component 21f stops discharging material, ensuring that there is at most one valve 6 between the third conveying and separating component 21f and the feeding module b4b, thereby adapting to the single feeding operation of the feeding module b4b).

[0122] The first linear actuator 213, the second linear actuator 214, the third linear actuator 451, the fourth linear actuator, and the fifth linear actuator 512 are all electric actuators, pneumatic actuators, hydraulic actuators, or combinations thereof (e.g., electro-hydraulic actuators).

[0123] The present invention also includes an electrical cabinet, which is fixedly installed on the floor of the processing workshop by bolts; the electrical control components such as the first linear driver 213, the second linear driver 214, the third linear driver 451, the fourth linear driver, the fifth linear driver 512, the first motor 116, the second motor, the third motor, and the sensing sensor 22 are respectively connected to the electrical cabinet through wires and signal lines; the electrical cabinet is connected to the external power supply and the external controller (such as a computer or a PLC programmable logic controller) through wires and signal lines, and the external controller controls the start and stop and other working states of the electrical control components such as the first linear driver 213, the second linear driver 214, the third linear driver 451, the fourth linear driver, the fifth linear driver 512, the first motor 116, the second motor, the third motor, and the sensing sensor 22 through the electrical cabinet.

[0124] The first motor 116, the second motor, and the third motor are controllable motors (such as servo motors or stepper motors). By inputting electrical signals to the controllable motors through an external controller, the speed, number of revolutions per rotation, angle of rotation per rotation, and start / stop timing of the controllable motors can be controlled.

[0125] The present invention has a simple structure and reliable function. When the valve 6 moves along the suspension groove 1110, it can push the end of the door plate 1123 and open the door plate 1123, so that the cavity inside the leakage hole 1122 generates negative pressure. Under the drive of negative pressure and combined with its own gravity, the mixed fluid can more easily leak downward (avoiding the mixed fluid from adhering to the upper straight groove 11201 / leak hole 1122), thereby avoiding the problem of metal debris and cutting fluid in the upper straight groove 11201 being scratched by metal debris.

[0126] When the clamping plate 44 is placed at the bottom of the fan-shaped plate 42, the opening of the adapter slot 441 faces upward, which is used to accommodate and receive the sliding valve 6 (that is, the rod part 62 of the valve 6 can be adapted to fall into the adapter slot 441); the rotating plate 43 can rotate 180 degrees, so that when the valve 6 is inserted into the grinding gap 520, the opening of the adapter slot 441 is in a downward state. Then, the valve 6 moves downward and passes through the grinding gap 520 (that is, it is grinding) and can be dislodged from the adapter slot 441 at the same time, realizing the convenient disengagement of the feeding module 4 from the valve 6, improving work efficiency and simplifying the mechanical structure.
