Description

Technical Field

[0001] The invention belongs to the technical field of workshop transportation, in particular to a water-cooling roller conveying device. Background Art

[0002] There are multiple processing areas in the existing workshop, and parts are transported between each processing area through transportation production lines. At present, when processing water-cooled rollers, the water-cooled rollers need to be transported to different price areas through conveyor lines; specifically, water-cooled rollers are a kind of mechanical equipment that realizes roller cooling through cooling water circulation. They are mainly used in the field of material processing to solve the problem of thermal damage in high temperature environment. Furthermore, water-cooled rollers are usually composed of roller bodies, roller shafts, rotary joints and cooling water channels. During processing, the water-cooled rollers need to undergo heat treatment, flaw detection, pressure resistance, wear resistance and cooling efficiency testing.

[0003] When transporting water-cooled rollers, the existing transport line places the water-cooled rollers on the loading end of the transport line through a robot, and then the transport line transports the water-cooled rollers to different processing areas. After reaching the designated processing area, the rollers are unloaded. The unloading process requires the transport line to stop running to ensure the stability of the water-cooled roller unloading process. However, in the actual transportation of water-cooled rollers, when the production period of the water-cooled rollers is short and the number of water-cooled rollers to be transported is large, the processing speed will be increased in different processing areas during production.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figures 1 to 2 As shown, a water-cooled roller conveying device according to an embodiment of the present invention includes a conveying line 1, the conveying line 1 includes a bracket and a conveying belt, and a plurality of pairs of limit strips are fixedly connected to the surface of the conveying belt;

[0038] A loading assembly 11 is installed at the loading end of the conveyor line 1, and multiple unloading plates 12 are installed on the side of the conveyor line 1. A circulating track 2 is installed on the side of the conveyor line 1 away from the unloading plate 12. A track trolley 31 is slidably connected inside the circulating track 2. The top of the track trolley 31 is fixedly connected to a support frame 3, and the top of the support frame 3 is fixedly connected to a unloading hydraulic cylinder 32. The output end of the unloading hydraulic cylinder 32 is fixedly connected to a unloading column 33. The top of the unloading plate 12 is provided with an arc-shaped inner concave surface.

[0039] When the existing workshop transports the water-cooled rollers, the transportation line needs to stop running when unloading. When the production period of the water-cooled rollers is short and the number of water-cooled rollers to be transported is large, the processing speed will be increased in different processing areas during production. It often happens that the transported water-cooled rollers do not reach the processing area, and the water-cooled rollers in the processing area have been processed. Therefore, in actual processing operations, the transportation efficiency of the water-cooled rollers needs to be further improved. In order to solve the above problems, the embodiment of the present invention is provided with a circulating track 2, a discharge plate 12 and other structures. The specific use process is as follows: When in use, the water-cooled rollers to be processed are transferred to the processing area through the loading assembly 11. On the conveyor belt of the conveyor line 1, and between a pair of limit bars on the conveyor belt, a driving structure is installed inside the conveyor belt, and the driving structure is a structure that drives the conveyor belt to rotate, including a motor, a driving roller, etc.; when the conveyor belt transports the water-cooled roller, the rail trolley 31 is started, and the rail trolley 31 drives the top support frame 3 to move, and the support frame 3 drives the unloading hydraulic cylinder 32 to move synchronously, and the unloading hydraulic cylinder 32 drives the unloading column 33 to move synchronously, and a photoelectric sensor is installed on the surface of the support frame 3 (not shown in the drawings of the specification), and the specific photoelectric sensor can identify the position of the water-cooled roller on the conveyor line 1, and the position is transmitted through the telecommunication The signal is transmitted to the rail trolley 31, and the rail trolley 31 controls its own speed according to the signal, so that the support frame 3 is aligned with the water-cooled roller to be unloaded, and then the unloading hydraulic cylinder 32 is started before the water-cooled roller moves to align with the unloading plate 12, and the output end of the unloading hydraulic cylinder 32 drives the unloading column 33 to move in the direction close to the water-cooled roller to be unloaded. At this time, the unloading column 33 is aligned with the water-cooled roller to be unloaded and moves synchronously. As the unloading column 33 moves further, the end of the water-cooled roller to be unloaded is squeezed between a pair of limit bars and moves. When the roller body of the water-cooled roller to be unloaded moves to the boundary of the conveyor belt, it is just embedded in the arc-shaped inner concave surface at the top of the unloading plate 12. The water-cooled roller is received by the arc-shaped inner concave surface at the top of the unloading plate 12, and then unloaded by the staff; the entire unloading process does not require the control of the conveyor line 1 to stop running, and multiple rail trolleys 31 can be set on the circulating track 2. Different rail trolleys 31 can carry the same structure for unloading different water-cooled rollers. Therefore, the unloading efficiency of the water-cooled roller is improved, which is conducive to the processing of large quantities of water-cooled rollers and solves the problem of low conveying efficiency affecting processing efficiency in the processing of water-cooled rollers with a short production period in large quantities; it should be pointed out that the unloading column 33 squeezes the roller shaft end of the water-cooled roller.

[0040] A support block 122 is fixedly connected between the bottom end of the discharge plate 12 and the bracket of the conveyor line 1, and a pair of guide rods 123 are inserted through the side of the support block 122. The support block 122 is located outside the bracket of the conveyor line 1, and the bottom end of the support block 122 located outside the bracket of the conveyor line 1 is fixedly connected to a buffer hydraulic cylinder 125, and a linkage plate 124 is fixedly connected between the output end of the buffer hydraulic cylinder 125 and the end of the guide rod 123; when the roller body of the water-cooled roller enters the arc-shaped inner concave surface on the discharge plate 12, the buffer hydraulic cylinder 125 is started synchronously, and the buffer hydraulic cylinder 125 drives the linkage plate 124 to move in the direction of movement of the water-cooled roller. A connecting block is fixedly connected between the linkage plate 124 and the discharge plate 12, so the linkage plate 124 will drive the discharge plate 12 to move synchronously , and the moving speed is the same as the moving speed of the water-cooled roller. Therefore, during the process of unloading the water-cooled roller from the conveyor line 1 to the unloading plate 12, the unloading plate 12 and the water-cooled roller remain relatively stationary, so that the water-cooled roller is stably transferred to the unloading plate 12 during unloading, ensuring the stability of unloading; when the water-cooled roller is completely transferred to the unloading plate 12, it is reset again, and the reset is controlled by the buffer hydraulic cylinder 125; it should be pointed out that when the unloading plate 12 moves relative to the bottom support block 122, the guide rod 123 synchronously penetrates the support block 122 to move, and then the guide rod 123 remains horizontal, and then the interlocking plate 124 connected to the guide rod 123 maintains horizontal movement, and the unloading plate 12 connected to the interlocking plate 124 maintains horizontal movement, and the movement of the unloading plate 12 remains stable.

[0041] A baffle 47 is provided at the top of the discharge plate 12 and located inside the arc-shaped inner concave surface. An inflation rod 46 is fixedly connected to the end of the baffle 47 away from the conveyor line 1. An inflation plate 45 is fixedly connected to the end of the inflation rod 46 away from the baffle 47. An air cylinder 4 is fixedly connected to the top of the discharge plate 12. The inflation plate 45 is inserted into the interior of the air cylinder 4. The top of the air cylinder 4 is connected and fixedly connected to a connector 41. A pair of inflation hoses 42 are connected and fixedly connected to the side of the connector 41. The ends of the inflation hoses 42 away from the connector 41 are connected and fixedly connected to an air bag 43. A limiting plate 44 is fixedly connected to the side of the air bag 43. The limiting plate 44 is fixedly connected to the top of the discharge plate 12.

[0042] When the water-cooled roller is transferred from the conveyor line 1 to the arc-shaped inner concave surface at the top of the discharge plate 12, the roller body of the water-cooled roller will squeeze the baffle 47. When the baffle 47 is squeezed, it drives the inflation rod 46 to move away from the conveyor line 1. The inflation rod 46 drives the inflation plate 45 to move inside the air cylinder 4. The air inside the air cylinder 4 is squeezed into the connector 41 and finally enters the airbag 43 through the inflation hose 42. The airbag 43 expands when it is inflated. When the airbag 43 expands, it adheres to the roller surface of the water-cooled roller, thereby drawing the water entering the arc-shaped inner concave surface. The cold roller restriction prevents the water-cooled roller from detaching from the top of the unloading plate 12; it should be pointed out that when the unloading plate 12 is braked, the water-cooled roller at the top of the unloading plate 12 will produce inertia, and the airbag 43 will prevent the water-cooled roller from detaching from the top of the unloading plate 12 due to inertia, further ensuring the stability of the water-cooled roller unloading; when the water-cooled roller on the unloading plate 12 is removed, the baffle 47 is no longer squeezed, and a spring is provided between the inflation plate 45 and the inner wall of the air cylinder 4. At this time, the spring is compressed by the inflation plate 45, and under the action of the spring elastic force, the inflation plate 45 drives the inflation rod 46 to reset.

[0043] There are multiple limiting springs fixed inside the airbag 43, and the two ends of the limiting springs are respectively connected to the bottom and top of the airbag 43 when it is not inflated; when the airbag 43 expands, the limiting springs inside the airbag 43 will limit the expansion direction of the airbag 43. Specifically, the upward expansion direction of the airbag 43 is limited, and the airbag 43 fully collides sideways to press and fix the roller surface of the water-cooled roller, thereby improving the limiting effect of the water-cooled roller.

[0044] The top of the discharge plate 12 is symmetrically fixed with two pairs of positioning plates 5 based on the air cylinder 4, and the inflation hose 42 passes between the pair of positioning plates 5; a plurality of extrusion springs 51 are fixed on the side of the positioning plate 5 facing the inflation hose 42, and a top block 52 is fixed on the end of the extrusion spring 51 close to the inflation hose 42, and the extrusion springs 51 between the pair of positioning plates 5 are staggered; the roller positions of water-cooled rollers of different sizes are different, so it is necessary to adjust the position of the limiting plate 44 according to the size of the water-cooled roller, and then adjust the expansion position of the airbag 43, so that the airbag 43 is stably pressed against the roller surface of the water-cooled roller after expansion, thereby ensuring the use effect of the airbag 43; when adjusting the position of the limiting plate 44 When the airbag 43 is positioned, the position of the airbag 43 is adjusted synchronously, so the inflation hose 42 connected to the airbag 43 may become loose and fall into the arc-shaped inner concave surface, and may be easily squeezed by the roller body of the water-cooled roller to produce dryness, which interferes with the gas flow and affects the movement of the water-cooled roller; therefore, a top block 52 is provided, and when the inflation hose 42 passes through a pair of positioning plates 5, the top block 52 squeezes the inflation hose 42 in an interlaced manner through the squeezing spring 51, so that the inflation hose 42 bends, thereby ensuring that the inflation hose 42 is tightened to avoid looseness. It should be pointed out that after the inflation hose 42 is squeezed in an interlaced manner, due to the internal air pressure, the degree of deformation is small, and dryness that interferes with the internal gas flow will not occur.

[0045] The arc-shaped inner concave surface at the top of the discharge plate 12 is slidably connected to a support bar 6, and a pair of connecting plates 61 are fixedly connected to the side of the support bar 6 away from the conveyor line 1, and a return spring 62 is fixed to the bottom end of the connecting plate 61. A pair of rectangular grooves 121 are symmetrically opened on the arc-shaped inner concave surface of the top of the discharge plate 12 based on the support bar 6, and the bottom end of the connecting plate 61 is inserted into the inside of the rectangular groove 121, and the end of the return spring 62 away from the connecting plate 61 is connected to the inner wall of the rectangular groove 121, and an inclined plate 63 is fixed to the inside of the rectangular groove 121; in the process of the water-cooled roller moving to the arc-shaped inner concave surface on the discharge plate 12, the roller body of the water-cooled roller will be supported by the support bar 6, and an arc-shaped rubber pad is provided at the top of the support bar 6. When the end of the water-cooled roller body passes through the support bar 6, the arc-shaped rubber pad is squeezed, and the water-cooled roller body is pressed against the surface of the arc-shaped rubber pad. The arc-shaped top end of the rubber pad is used to support the end of the water-cooled roller body, and between the support bar 6 and the water-cooled roller When the loading plate 61 is lifted up, the bottom end of the connecting plate 61 is continuously supported by the inclined surface of the inclined plate 63, thereby causing the connecting plate 61 to drive the support bar 6 to gradually move upward, thereby causing the water-cooled roller on the inner concave surface of the arc to be supported by the support bar 6 and tilted, which is convenient for the staff to remove the water-cooled roller on the inner concave surface of the arc, and avoid the roller shaft of the water-cooled roller being located in the inner concave surface of the arc and difficult to grab; after the water-cooled roller is removed from the inner concave surface of the arc, the reset spring 62 will press the connecting plate 61 to reset, so that the connecting plate 61 drives the support bar 6 to reset; it should be pointed out that when the water-cooled roller on the unloading plate 12 is removed by the manipulator, it is also necessary to grab the roller shaft of the water-cooled roller, so it is necessary to drive the roller shaft of the water-cooled roller to the top of the unloading plate 12 when unloading.

[0046] The end of the unloading column 33 facing the conveying line 1 is provided with a circular groove, and a first air plate 34 is slidably connected to the inside of the circular groove. A vent is provided on the side of the first air plate 34, and an extension tube 36 is connected and fixed to the orifice of the vent. A second air plate 37 is slidably connected to the inside of the extension tube 36, and a tension spring 35 is fixed between the second air plate 37 and the inner wall of the circular groove. An air pipe is fixed to the side of the unloading column 33, and the air pipe passes through the sealing area formed by the first air plate 34 and the second air plate 37 in the circular groove. An extension column 38 is fixed on the side of the second air plate 37 away from the tension spring 35, and a plurality of baffles 39 are fixed in an annular shape at the notch of the circular groove; when unloading, the air pipe is inflated by an external air pump, and the air pipe injects air into the circular groove. Under the action of air pressure, the first air plate 34 moves to the notch position of the circular groove and is blocked when it contacts the baffle 39. Later, as the air pressure inside the circular groove further increases, the second air plate 37 will move further inside the extension tube 36, so that the second air plate 37 drives the extension column 38 to move toward the direction close to the conveyor line 1, and the tension spring 35 limits the movement position of the second air plate 37 inside the extension tube 36 to prevent the second air plate 37 from separating from the extension tube 36. Based on the above, the extension column 38 will extend from the unloading column 33, and then when the output end of the unloading hydraulic cylinder 32 drives the unloading column 33 to squeeze the roller shaft of the water-cooled roller, the extension column 38 will be squeezed to the roller shaft end of the water-cooled roller, and then squeeze the water-cooled roller to transfer to the unloading plate 12, realizing the unloading of the water-cooled roller. The entire unloading process does not require the unloading hydraulic cylinder 32 to output a large displacement, thereby effectively reducing the size of the unloading hydraulic cylinder 32 and thus reducing costs; in addition, the position of the extension column 38 can be flexibly adjusted according to the size of the water-cooled roller, which is convenient for use.

[0047] The loading assembly 11 includes a first loading plate 7, which is located above the loading end of the conveyor line 1 and is set in an inclined state. A pair of blocking plates 75 are provided at the bottom end of the first loading plate 7. A pair of first guardrail plates are symmetrically fixed on both sides of the first loading plate 7. A loading hydraulic cylinder 74 is fixed on the side of the first guardrail plate. A connecting frame is fixed between the output end of the loading hydraulic cylinder 74 and the blocking plate 75. When loading the conveyor line 1, the water-cooled roller is stacked on the surface of the inclined first loading plate 7. The bottom end of the first loading plate 7 is located just above the loading end of the conveyor line 1 and is blocked by the blocking plate 75. When loading, the loading hydraulic cylinder 74 is started, and the output end of the loading hydraulic cylinder 74 drives the blocking plate 75 to move through the connecting frame, so that the blocking plate 75 no longer blocks the water-cooled roller at the bottom. The water-cooled roller at the bottom will fall between a pair of limit bars at the loading end of the conveyor line 1 and be fixed by the pair of limit bars. After that, the blocking plate 75 is controlled to reset, and the water-cooled roller on the first loading plate 7 moves downward. The rolling is blocked by the blocking plate 75, and then the above operation is repeated. The water-cooled roller on the first loading plate 7 is gradually loaded onto the conveyor line 1. In this process, the conveyor line 1 can operate continuously. The staff only needs to load the water-cooled roller onto the first loading plate 7. It should be pointed out that the loading hydraulic cylinder 74 is controlled by a microcomputer, and the water-cooled roller can accurately fall between a pair of limit bars on the running conveyor belt each time to ensure stable loading. The conveyor line 1 does not need to stop running during loading, which is conducive to further improving the transportation efficiency of the water-cooled roller; in addition, loading by a manipulator requires the manipulator to rotate and keep moving synchronously with the conveyor line 1, and it is necessary to repeatedly swing the manipulator arm. The loading process is relatively cumbersome and requires setting a complex manipulator movement program, which is relatively inconvenient; the above-mentioned loading process of the present invention is relatively simple and can be loaded continuously. When the water-cooled roller falls onto the conveyor belt on the conveyor line 1, since the water-cooled roller falls a limited distance and is supported by a pair of limit bars, it will not cause damage to the conveyor line 1.

[0048] A servo motor 73 is fixedly connected to the side of the first guardrail plate, and a roller 71 is fixedly connected to the output end of the servo motor 73. The wheel surface of the roller 71 is annular and fixedly connected with a plurality of gaskets 72. When the lowermost water-cooled roller on the first loading plate 7 falls onto the conveyor line 1, the servo motor 73 is started, driving the roller 71 to rotate 90 degrees counterclockwise, and the roller 71 drives the gasket 72 to rotate synchronously, so that the gasket 72 is inserted between the pair of water-cooled rollers above. The gasket 72 has a certain strength and can be smoothly inserted between the pair of water-cooled rollers. No bending will occur, and the servo motor 73 rotates slowly. The lowest gasket 72 can hinder the downward rolling of the upper water-cooled roller, thereby delaying the time for the water-cooled roller to roll to the bottom of the first loading plate 7, reserving time for the blocking plate 75 to reset, and preventing the water-cooled roller from rolling too fast, causing the blocking plate 75 to not have time to reset and block the water-cooled roller; at the same time, reduce the rolling speed of the water-cooled roller to avoid the water-cooled roller hitting the blocking plate 75 too fast, causing vibration between the water-cooled rollers, and then causing damage.

[0049] The top of the first loading plate 7 is rotatably connected to the second loading plate 8, and the two sides of the second loading plate 8 are fixedly connected to a pair of second guardrail plates, and the side surfaces of the second guardrail plates are provided with a plurality of positioning holes, and the positioning holes are inserted with positioning posts 82. The ends of the positioning posts 82 located outside the positioning holes are fixedly connected to an adjusting plate 81, and the ends of the adjusting plate 81 away from the positioning posts 82 are fixedly connected to the side surfaces of the first guardrail plates; when in use, the water-cooled roller can be placed on the second loading plate 8, and the second loading plate 8 can be positioned at an angle by the positioning posts 82 and the adjusting plate 81 after the second loading plate 8 is rotated relative to the first loading plate 7. Specifically, after the angle of the second loading plate 8 is adjusted, the positioning posts 82 are inserted into the positioning holes, and then the adjusting plate 81 is fixed to the side surfaces of the first guardrail plates, and the second loading plate 8 buffers the loading process. After the angle adjustment of the second loading plate 8 is completed, the angle between the second loading plate 8 and the horizontal plane is small, so that the water-cooled roller on the second loading plate 8 can slowly roll to the surface of the first loading plate 7, avoiding the water-cooled roller from piling up higher on the first loading plate 7 and causing dangerous accidents.
