Description

Technical Field

[0001] The present invention belongs to the technical field of workshop transportation, and specifically relates to a water-cooled roller conveying device. Background Art

[0002] There are multiple processing areas in the existing workshop, and parts are conveyed between each processing area through a transportation production line. Currently, when processing a water-cooled roller, it is necessary to transport the water-cooled roller to different processing areas through a conveyor line; specifically, a water-cooled roller is a mechanical device that realizes the cooling of the roller body through the circulation of cooling water, mainly used in the field of material processing to solve the problem of thermal damage in a high-temperature environment. Further, a water-cooled roller usually consists of a roller body, a roller shaft, a rotary joint, and a cooling water channel. During processing, heat treatment, flaw detection, pressure resistance, wear resistance, and cooling efficiency testing and other processes need to be carried out on the water-cooled roller.

[0003] When the existing conveyor line conveys a water-cooled roller, a manipulator places the water-cooled roller at the loading end of the conveyor line, and then the conveyor line conveys the water-cooled roller to different processing areas. After reaching the designated processing area, unloading is carried out. During the unloading process, the conveyor line needs to stop running to ensure the stability of the water-cooled roller unloading process. However, in the actual transportation of the water-cooled roller, when the production period of the water-cooled roller 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, and it often occurs that the conveyed water-cooled roller has not reached the processing area, while the water-cooled roller in the processing area has been processed. Therefore, in the actual processing operation, the conveying efficiency of the water-cooled roller needs to be further improved.

[0016] The beneficial effects of the present invention are as follows: 1. For the water-cooled roller conveying device of the present invention, by setting a circulating track; during use, the unloading column rotates on the circulating track. Before the water-cooled roller moves to align with the unloading plate, the unloading hydraulic cylinder is activated. The output end of the unloading hydraulic cylinder drives the unloading column to move towards the water-cooled roller to be unloaded. When the roller body of the water-cooled roller to be unloaded moves to the boundary of the conveyor belt, it just fits into the arc-shaped concave surface at the top of the unloading plate. The water-cooled roller is received through the arc-shaped concave surface at the top of the unloading plate, and then removed by the staff. During the entire unloading process, there is no need to control the conveyor line to stop running. Moreover, multiple track trolleys can be set on the circulating track, and different track trolleys can carry the same structure for unloading different water-cooled rollers. Therefore, the unloading efficiency of the water-cooled roller is improved, which is beneficial to the processing of a large number of water-cooled rollers, and solves the problem that the conveying efficiency is low and affects the processing efficiency during the processing of water-cooled rollers with a short production period in large quantities. It should be noted that the unloading column presses the end of the roller shaft of the water-cooled roller.

[0017] 2. For the water-cooled roller conveying device of the present invention, by setting a baffle; when the water-cooled roller transfers from the conveyor line to the arc-shaped concave surface at the top of the unloading plate, the roller body of the water-cooled roller will squeeze the baffle. When the baffle is squeezed, it drives the inflating rod to move away from the conveyor line. The inflating rod drives the inflating plate to move inside the air cylinder. The air inside the air cylinder is squeezed into the connecting head and finally enters the airbag through the inflating hose. When the airbag is inflated, it expands. When the airbag expands, it adheres to the surface of the roller body of the water-cooled roller, thereby restricting the water-cooled roller entering the arc-shaped concave surface and preventing the water-cooled roller from detaching from the top of the unloading plate.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 2 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 conveyor belt, and a plurality of pairs of limiting strips are fixedly connected to the surface of the conveyor belt; A feeding assembly 11 is installed at the feeding end of the conveying line 1, a plurality of discharging plates 12 are installed on the side of the conveying line 1, a circulating track 2 is installed on the side of the conveying line 1 away from the discharging plate 12, a track car 31 is slidably connected inside the circulating track 2, a support frame 3 is fixedly connected to the top of the track car 31, a discharging hydraulic cylinder 32 is fixedly connected to the top of the support frame 3, a discharging column 33 is fixedly connected to the output end of the discharging hydraulic cylinder 32, and an arc-shaped concave surface is opened at the top of the discharging plate 12; When transporting water-cooled rollers in the existing workshop, the transportation line needs to stop running during 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. Often, the transported water-cooled rollers have not reached the processing area, while 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. To solve the above problems, the embodiment of the present invention is provided with structures such as a circular track 2 and a discharge plate 12. The specific use process is as follows: During use, the water-cooled rollers to be processed are transferred to the conveyor belt of the conveyor line 1 through the feeding assembly 11 and are located between a pair of limiting strips on the conveyor belt. A driving structure is installed inside the conveyor belt. The driving structure is a structure that drives the conveyor belt to rotate and includes a motor, a driving roller, etc. When the conveyor belt transports the water-cooled rollers, the track trolley 31 starts. The track trolley 31 drives the top support frame 3 to move. The support frame 3 drives the discharge hydraulic cylinder 32 to move synchronously. The discharge hydraulic cylinder 32 drives the discharge column 33 to move synchronously. A photoelectric sensor (not shown in the specification drawings) is installed on the surface of the support frame 3. Specifically, the photoelectric sensor can identify the position of the water-cooled rollers on the conveyor line 1 and transmit the position to the track trolley 31 through an electrical signal. The track trolley 31 controls its own speed according to the signal, so that the support frame 3 is aligned with the water-cooled rollers to be unloaded. Then, before the water-cooled rollers move to be aligned with the discharge plate 12, the discharge hydraulic cylinder 32 starts. The output end of the discharge hydraulic cylinder 32 drives the discharge column 33 to move towards the direction close to the water-cooled rollers to be unloaded. At this time, the discharge column 33 is aligned with the water-cooled rollers to be unloaded and moves synchronously. As the discharge column 33 moves further, the end of the water-cooled roller to be unloaded is squeezed and moves between a pair of limiting strips. When the roller body of the water-cooled roller to be unloaded moves to the boundary of the conveyor belt, it just fits into the arc-shaped concave surface at the top of the discharge plate 12. The water-cooled roller is received through the arc-shaped concave surface at the top of the discharge plate 12, and then is removed by the staff. The entire unloading process does not require controlling the conveyor line 1 to stop running. Multiple track trolleys 31 can be set on the circular track 2. Different track trolleys 31 can carry the same structure to unload different water-cooled rollers. Therefore, the unloading efficiency of the water-cooled rollers is improved, which is beneficial to the processing of a large number of water-cooled rollers and solves the problem that the transportation efficiency is low and affects the processing efficiency during the processing of a large number of water-cooled rollers with a short production period. It should be noted that the discharge column 33 squeezes the end of the roller shaft of the water-cooled roller.

[0023] A support block 122 is fixedly connected between the bottom end of the unloading 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 partially located outside the bracket of the conveyor line 1, and a buffer hydraulic cylinder 125 is fixedly connected to the bottom end of the support block 122 located outside the bracket of the conveyor line 1, 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 unloading plate 12, the buffer hydraulic cylinder 125 is synchronously started, and the buffer hydraulic cylinder 125 drives the linkage plate 124 to move in the direction of the movement of the water-cooled roller. A connecting block is fixedly connected between the linkage plate 124 and the unloading plate 12, so the linkage plate 124 will drive the unloading 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 still, 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.

[0024] A baffle plate 47 is provided at the top of the discharge plate 12 and located inside the arc-shaped inner concave surface, an inflatable rod 46 is fixedly connected to the end of the baffle plate 47 away from the conveyor line 1, an inflatable plate 45 is fixedly connected to the end of the inflatable rod 46 away from the baffle plate 47, an air cylinder 4 is fixedly connected to the top of the discharge plate 12, the inflatable plate 45 is plugged into the inside of the air cylinder 4, the top of the air cylinder 4 is connected and fixedly connected to a connector 41, the side of the connector 41 is connected and fixedly connected to a pair of inflatable hoses 42, the end of the inflatable hose 42 away from the connector 41 is connected and fixedly connected to an air bag 43, the side of the air bag 43 is fixedly connected to a limiting plate 44, and the limiting plate 44 is fixedly connected to the top of the discharge plate 12; When the water-cooled roller transfers from the conveying line 1 to the arc-shaped concave surface at the top of the unloading 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 conveying 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. When the airbag 43 is inflated, it expands. When the airbag 43 expands, it adheres to the surface of the roller body of the water-cooled roller, thereby restricting the water-cooled roller entering the arc-shaped concave surface and preventing the water-cooled roller from detaching from the top of the unloading plate 12. It should be noted that when the unloading plate 12 brakes, the water-cooled roller at the top of the unloading plate 12 will generate an inertial effect, 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. A spring is arranged 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. Under the action of the spring force, the inflation plate 45 drives the inflation rod 46 to reset.

[0025] A plurality of limiting springs are fixedly connected inside the airbag 43. The two ends of the limiting springs are respectively connected to the bottom end and the top end inside 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 laterally to press and fix the surface of the roller body of the water-cooled roller, improving the limiting effect on the water-cooled roller.

[0026] Two pairs of positioning plates 5 are symmetrically fixedly connected to the top of the unloading plate 12 based on the air cylinder 4. The inflation hose 42 passes through between a pair of positioning plates 5. A plurality of extrusion springs 51 are fixedly connected to the side of the positioning plate 5 facing the inflation hose 42. A top block 52 is fixedly connected to the end of the extrusion spring 51 close to the inflation hose 42. The extrusion springs 51 between a pair of positioning plates 5 are staggered. The roller body positions of water-cooled rollers of different sizes are different. Therefore, 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 inflation position of the airbag 43, so that the airbag 43 stably presses against the surface of the roller body of the water-cooled roller after inflation, thereby ensuring the use effect of the airbag 43. When adjusting the position of the limiting plate 44, the position of the airbag 43 is adjusted synchronously. Therefore, the inflation hose 42 connected to the airbag 43 may become loose and fall into the arc-shaped concave surface, and is easily squeezed by the roller body of the water-cooled roller to produce dryness and interfere with gas flow, and affect the movement of the water-cooled roller. Therefore, the top block 52 is provided. When the inflation hose 42 passes through a pair of positioning plates 5, the top block 52 alternately squeezes the inflation hose 42 through the extrusion spring 51, making the inflation hose 42 bend, thereby ensuring that the inflation hose 42 is tightened and avoiding looseness. It should be noted that after the inflation hose 42 is alternately squeezed, due to the internal air pressure, the degree of deformation is small and it will not produce dryness that interferes with the internal gas flow.

[0027] An arc-shaped concave surface at the top of the unloading plate 12 is slidably connected with a support bar 6. On the side of the support bar 6 away from the conveyor line 1, a pair of connecting plates 61 are fixedly connected. At the bottom end of the connecting plate 61, a return spring 62 is fixedly connected. A pair of rectangular grooves 121 are symmetrically formed on the arc-shaped concave surface at the top of the unloading plate 12 based on the support bar 6. The bottom end of the connecting plate 61 is inserted into the interior of the rectangular groove 121. The end of the return spring 62 away from the connecting plate 61 is connected to the inner wall of the rectangular groove 121. An inclined plate 63 is fixedly connected inside the rectangular groove 121; during the process of the water-cooled roller moving onto the arc-shaped concave surface on the unloading plate 12, the roller body of the water-cooled roller will be received by the support bar 6. An arc-shaped rubber pad is arranged at the top of the support bar 6. When the end of the roller body of the water-cooled roller passes by the support bar 6, the arc-shaped rubber pad is squeezed, and the roller body of the water-cooled roller is pressed onto the surface of the arc-shaped rubber pad. The arc-shaped top of the rubber pad is used to receive the end of the roller body of the water-cooled roller. There is a frictional force between the support bar 6 and the water-cooled roller. As the water-cooled roller moves further, the support bar 6 is driven by the frictional force to slide within the arc-shaped concave surface at the top of the unloading plate 12. When the support bar 6 moves, it drives the connecting plate 61 to move synchronously. When the connecting plate 61 moves, its bottom end is continuously lifted 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, and then resulting in the water-cooled roller on the arc-shaped concave surface being supported by the support bar 6 and tilting, which is convenient for the staff to remove the water-cooled roller on the arc-shaped concave surface later and avoids the roller shaft of the water-cooled roller being difficult to grasp within the arc-shaped concave surface; after the water-cooled roller is removed from the arc-shaped concave surface, the return spring 62 will press and reset the connecting plate 61, causing the connecting plate 61 to drive the support bar 6 to reset; it should be noted that when removing the water-cooled roller on the unloading plate 12 by a manipulator, it is also necessary to grasp the roller shaft of the water-cooled roller. Therefore, it is necessary to drive the roller shaft of the water-cooled roller above the unloading plate 12 during unloading.

[0028] The end of the unloading column 33 facing the conveying line 1 is provided with a circular groove. A first air plate 34 is slidably connected inside the circular groove. Vent holes are provided on the side surface of the first air plate 34. An extension cylinder 36 is fixedly connected to the orifice of the vent hole. A second air plate 37 is slidably connected inside the extension cylinder 36. A tension spring 35 is fixedly connected between the second air plate 37 and the inner wall of the circular groove. An air pipe is fixedly connected to the side surface of the unloading column 33. The air pipe penetrates into the sealed area formed by the first air plate 34 and the second air plate 37 inside the circular groove. An extension column 38 is fixedly connected to the side of the second air plate 37 away from the tension spring 35. A plurality of retaining pieces 39 are fixedly connected in a ring shape at the orifice of the circular groove; during unloading, the air pipe is inflated by an external air pump. The air pipe injects air into the circular groove. Under the action of air pressure, the first air plate 34 moves towards the orifice position of the circular groove and is blocked when contacting the retaining piece 39. Then, as the air pressure inside the circular groove further increases, the second air plate 37 will further move inside the extension cylinder 36, causing the second air plate 37 to drive the extension column 38 to move towards the conveying line 1. The tension spring 35 limits the moving position of the second air plate 37 inside the extension cylinder 36 to prevent the second air plate 37 from detaching from the extension cylinder 36. Based on the above, the extension column 38 will protrude from the unloading column 33. 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 squeeze the end of the roller shaft of the water-cooled roller, and then squeeze the water-cooled roller onto the unloading plate 12 to achieve the unloading of the water-cooled roller. The entire unloading process does not require the output end of the unloading hydraulic cylinder 32 to have a large displacement, which can effectively reduce the size of the unloading hydraulic cylinder 32 and thus reduce 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.

[0029] The feeding component 11 includes a first feeding plate 7. The first feeding plate 7 is located above the feeding 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 feeding plate 7. A pair of first guard plates are symmetrically and fixedly connected to both sides of the first feeding plate 7. A feeding hydraulic cylinder 74 is fixedly connected to the side surface of the first guard plate. A connecting frame is fixedly connected between the output end of the feeding hydraulic cylinder 74 and the blocking plate 75. When feeding the conveyor line 1, the water-cooled rollers are stacked on the surface of the inclined first feeding plate 7. The bottom end of the first feeding plate 7 is directly above the feeding end of the conveyor line 1. The blocking plate 75 is used for blocking and intercepting. When feeding, the feeding hydraulic cylinder 74 is started. The output end of the feeding hydraulic cylinder 74 drives the blocking plate 75 to move through the connecting frame, so that the blocking plate 75 no longer blocks the lowermost water-cooled roller. The lowermost water-cooled roller will fall between a pair of limiting strips at the feeding end of the conveyor line 1 and is fixed by the pair of limiting strips. Then, the blocking plate 75 is controlled to reset. The water-cooled rollers on the first feeding plate 7 roll downward and are blocked by the blocking plate 75. Then, the above operation is repeated. The water-cooled rollers on the first feeding plate 7 are gradually fed onto the conveyor line 1. During this process, the conveyor line 1 can operate continuously. The staff only needs to feed the water-cooled rollers onto the first feeding plate 7. It should be noted that the feeding hydraulic cylinder 74 is controlled by a microcomputer. Each time, the water-cooled roller can accurately fall between a pair of limiting strips on the running conveyor belt, ensuring stable feeding. And when feeding, the conveyor line 1 does not need to stop operating, which is beneficial to further improving the feeding efficiency of the water-cooled rollers. In addition, when feeding by a manipulator, the manipulator needs to rotate synchronously with the conveyor line 1 to keep moving, and the manipulator arm needs to be waved repeatedly. The feeding process is relatively cumbersome, and a complex manipulator movement program needs to be set, which is rather inconvenient. The above feeding process of the present invention is relatively simple and can feed continuously. When the water-cooled roller falls onto the conveyor belt of the conveyor line 1, since the falling distance of the water-cooled roller is limited and it is received by a pair of limiting strips, the conveyor line 1 will not be damaged.

[0030] A servo motor 73 is fixedly connected to the side surface of the first guard plate. The output end of the servo motor 73 is fixedly connected with a roller 71. A plurality of gaskets 72 are annularly fixedly connected to the wheel surface of the roller 71. When the lowermost water-cooled roller on the first feeding plate 7 falls onto the conveyor line 1, the servo motor 73 is started to drive the roller 71 to rotate counterclockwise by 90 degrees. The roller 71 drives the gaskets 72 to rotate synchronously, so that the gaskets 72 are inserted between the upper pair of water-cooled rollers. The gaskets 72 have a certain strength and can be smoothly inserted between the pair of water-cooled rollers without bending. And the rotation speed of the servo motor 73 is relatively slow. The lowermost gasket 72 can hinder the downward rolling of the upper water-cooled rollers, thereby delaying the time for the water-cooled rollers to roll to the lowermost part of the first feeding plate 7, reserving time for the reset of the blocking plate 75, and preventing the blocking plate 75 from not having enough time to reset to block the water-cooled rollers due to the too fast rolling speed of the water-cooled rollers. At the same time, the rolling speed of the water-cooled rollers is reduced, avoiding the vibration generated between the water-cooled rollers due to the too fast impact speed of the water-cooled rollers against the blocking plate 75, and thus preventing damage.

[0031] The top end of the first loading plate 7 is rotatably connected to a second loading plate 8. A pair of second guard plates are fixedly connected to both sides of the second loading plate 8. A plurality of positioning holes are formed in the side surface of the second guard plate. A positioning post 82 is inserted into the positioning hole. One end of the positioning post 82 located outside the positioning hole is fixedly connected to an adjusting plate 81. The end of the adjusting plate 81 away from the positioning post 82 is fixedly connected to the side surface of the first guard plate. When in use, the water-cooled roller can be placed on the second loading plate 8. After the second loading plate 8 rotates relative to the first loading plate 7 by an angle, the angle can be positioned by the positioning post 82 and the adjusting plate 81. Specifically, after the angle of the second loading plate 8 is adjusted, the positioning post 82 is inserted into the positioning hole, and then the adjusting plate 81 is fixed to the side surface of the first guard plate. The second loading plate 8 buffers the loading process. After the angle of the second loading plate 8 is adjusted, 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 onto the surface of the first loading plate 7, avoiding the water-cooled rollers piling up higher and higher on the first loading plate 7 and causing dangerous accidents.
