Description

Technical Field

[0001] The invention relates to the field of industrial production, in particular to a belt conveyor for a stamping production line. Background Art

[0002] Belt conveyors are commonly used conveying tools in production lines. In stamping production lines, belt conveyors are required to be higher. However, the inventors found that existing belt conveyors have the following problems:

[0003] 1) The service length of the belt conveyor is limited, and the effective length of the belt conveyor cannot be adjusted according to actual working conditions.

[0004] 2) The belt conveyor is not only used to transport the blanks or workpieces between various processes, but also to meet the stamping action of heavy equipment. However, the existing stamping belt conveyor cannot meet this requirement. In addition, the existing belt conveyor cannot meet the blanking height and packing height of different parts.

[0005] 3) The scope of use is limited, and it cannot be quickly moved to different working positions required by different parts, resulting in low production efficiency. Summary of the invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a belt conveyor for a stamping production line, which can achieve extension and retraction in length to meet the demand that the length of the stamping belt conveyor can be adjusted in time, and can also achieve lifting and lowering to meet the blanking height and packing height of different parts, and can also be moved to different working positions required by different parts.

[0007] A specific scheme for a belt conveyor for a stamping production line is as follows:

[0008] A belt conveyor for a stamping production line comprises a belt conveyor body, the belt conveyor body comprises a fixed component, a telescopic component and a belt, the telescopic component can realize telescopic movement relative to the fixed component, the fixed component comprises an active roller and a first roller, the telescopic component comprises a driven roller and a second roller, the belt is supported by the active roller, the driven roller, the first roller and the second roller in sequence, the second roller is arranged higher than the first roller, and the belt bypasses the second roller and moves in the reverse direction, and during the telescopic process of the telescopic component, the driven roller and the second roller are driven to move, thereby realizing the telescopic movement of the belt conveyor.

[0009] The above-mentioned stamping belt conveyor effectively extends the length of the belt through the setting of the first roller and the second roller. In this way, during the telescopic movement of the telescopic part relative to the fixed part, the length of the belt is gradually released because the belt bypasses the second roller setting, and the usable length of the belt is correspondingly extended or shortened, thereby effectively realizing the extension and retraction of the belt. The overall setting is reasonable and effectively broadens the scope of application of the belt conveyor.

[0010] Furthermore, the active roller and the first roller in the fixed component are supported by a fixed frame, a plurality of first rollers are installed between the active roller and the first roller, a first plate is provided on the side of the first roller, the first roller and the first steel plate support the belt, and through the arrangement of the first roller and the first plate, the belt is effectively supported from below the upper surface of the belt to avoid the sinking of the belt, thereby ensuring the stability and reliability of the belt transmission, and the first roller is a round roller, and there is rolling friction between the first roller and the belt, which can correspondingly reduce the wear on the belt and extend the service life of the belt.

[0011] Furthermore, the driven roller and the second roller in the telescopic component are supported by a telescopic frame, and the telescopic frame can realize telescopic movement relative to the fixed frame. A plurality of second rollers are provided between the driven roller and the second roller, and a second plate is provided between two adjacent second rollers. The setting height of the second plate is lower than the setting height of the first plate. The second rollers are also circular rollers. The second plate is also used to support the belt, and the second plate is lower than the first steel plate, so as to facilitate the telescopic movement of the telescopic component relative to the fixed component.

[0012] Furthermore, a first fixed frame is installed under the first plate, and there is a set distance between the first plate and the first fixed frame. The first fixed frame is supported by the fixed frame. There are multiple first fixed frames, and both ends of the first fixed frame and both ends of the first plate are supported by the fixed frame. The first plate is a steel plate.

[0013] Furthermore, a second fixed frame is provided below the second plate, the second fixed frame is supported by the telescopic frame, there is a set distance between the second plate and the second fixed frame, both ends of the second plate are also supported by the telescopic frame, and the second plate is also a steel plate.

[0014] Furthermore, a telescopic mechanism is provided between the telescopic frame and the fixed frame.

[0015] Furthermore, the telescopic mechanism includes a rack provided on the telescopic frame and a gear provided on the fixed frame, the gear is meshed with the rack, the gear is connected to a power mechanism, the power mechanism drives the gear to rotate, and then promotes the telescopic movement of the rack and the telescopic frame relative to the fixed frame, the gear is provided on the driven shaft, and the power mechanism is provided on the fixed frame or the base, so that the power mechanism drives the gear to rotate through the sprocket transmission mechanism, and then drives the movement of the rack.

[0016] Furthermore, the belt conveyor body is arranged on the base, and a lifting mechanism for lifting the belt conveyor body is arranged between the belt conveyor body and the base. The lifting mechanism is arranged on both sides of the base and can respectively drive the head end and the tail end of the belt conveyor to lift and lower respectively.

[0017] Furthermore, the base is provided with a lateral shift force member, which is connected to a lateral shift transmission shaft, which is arranged along the length direction of the belt conveyor body, and both ends of the lateral shift transmission shaft are respectively connected to lateral shift wheels, which are perpendicular to the lateral shift transmission shaft. When the belt conveyor is arranged on the ground, the lateral shift wheels can contact the ground, and the lateral shift force member drives the lateral shift transmission shaft to rotate, thereby driving the lateral shift wheels to roll relative to the ground, thereby driving the entire belt conveyor to move sideways;

[0018] The base is also provided with a second shaft parallel to the side shift transmission shaft, and driven wheels are arranged at both ends of the second shaft. When the side shift wheel moves, the corresponding driven wheel moves, thereby driving the entire belt conveyor to move.

[0019] Furthermore, a folding platform is provided on the side of the base, and the folding platform can be rotated relative to the base, so that the staff can stand on the surface of the folding platform to work, and the folding platform can be folded and stored when not needed.

[0020] The entire stamping belt conveyor can realize sideways movement and the lifting and lowering of the belt conveyor body through the setting of the side shift wheel. The height of the belt conveyor body can be adjusted according to the height of the object to be conveyed. In addition, through the setting of the telescopic part and the fixed part, the movement of the telescopic part relative to the fixed part can be realized, thereby extending the length of the belt conveyor body. Moreover, the belt is effectively supported in the belt conveyor body to ensure the flatness of the belt setting. The entire stamping belt conveyor can better meet the different needs of the stamping production line.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) The present invention supports the belt through multiple rollers. The belt reverses at the second roller. The telescopic component can realize telescopic movement relative to the fixed component.

[0023] 2) The present invention effectively supports the belt from the fixed part by setting the first roller and the first plate, and effectively supports the belt from the telescopic part by setting the second roller and the second plate, so that the rigidity of the belt is enhanced and the influence on the telescopic part is fully avoided.

[0024] 3) The present invention not only improves the strength and rigidity of the belt conveyor body by arranging the first roller and the second roller, but also makes the friction on the belt rolling friction, thereby correspondingly improving the service life of the belt.

[0025] 4) The stamping line has parts or molds with different arrangements, which will result in different discharge positions of the parts. The present invention can effectively drive the entire belt conveyor to move lateraly through the setting of the side shift wheel, and can quickly move the belt conveyor to the required working position.

DETAILED DESCRIPTION

[0039] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0040] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0041] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present invention proposes a belt conveyor for a stamping production line. The present invention is further explained below in conjunction with the accompanying drawings of the specification.

[0042] In a typical embodiment of the present invention, Figure 1-Figure 3 As shown, a belt conveyor for a stamping production line includes a belt conveyor body 1, the belt conveyor body 1 includes a fixed component, a telescopic component and a belt 6, the telescopic component can realize telescopic movement relative to the fixed component, the fixed component includes an active roller 17 and a first roller, the telescopic component includes a driven roller 9 and a second roller, the belt 6 is supported by the active roller 17, the driven roller 9, the first roller and the second roller in sequence, the second roller is set higher than the first roller, and the belt 6 bypasses the second roller to reverse, and during the telescopic process of the telescopic component, the driven roller and the second roller are driven to move, thereby realizing the telescopic of the belt conveyor, wherein the first roller is a tensioning roller 14, the second roller is a reverse roller 15, the active roller 17 and the driven roller 9 are set at the same height or the active roller 9 is set higher than the active roller, the size of the driven roller 9 is smaller than the active roller 17, and the reverse roller 15 is set lower than the driven roller 9, so that the belt 6 can reverse at the reverse roller 15, and in the initial position, the distance between the tensioning roller 14 and the driven roller 9 is smaller than the distance between the driven roller and the reverse roller.

[0043] The above-mentioned stamping belt conveyor effectively extends the length of the belt 6 through the setting of the first roller and the second roller. In this way, during the telescopic movement of the telescopic part relative to the fixed part, because the belt 6 bypasses the second roller setting, the length of the belt is gradually released, and the usable length of the belt is correspondingly extended or shortened, thereby effectively realizing the extension and retraction of the belt. The overall setting is reasonable and effectively broadens the scope of application of the belt conveyor.

[0044] The active roller 17 and the tensioning roller 14 in the fixed component are supported by a fixed frame, and the active roller 17 is connected to the active motor 4. When the active motor works, it drives the belt to run. A plurality of first rollers 16 are installed between the active roller 17 and the tensioning roller 14. A first plate is provided on the side of the first roller 16. The first plate 27 and the first roller 16 are supported by a fixed frame. The first roller 16 is not provided on the side of the first plate 27 close to the telescopic frame. The first roller 16 and the first plate 27 support the belt 6. Through the arrangement of the first roller 16 and the first plate 27, the belt 6 is effectively supported from below the upper surface of the belt 6 to avoid the sinking of the belt, thereby ensuring the stability and reliability of the belt transmission and improving the weight-bearing capacity of the belt. The first roller 16 is a round roller, and there is rolling friction between the first roller 16 and the belt 6, which can reduce the wear on the belt 6 accordingly and extend the service life of the belt 6.

[0045] The driven roller 9 and the reverse roller 15 in the telescopic component are supported by a telescopic frame, and the telescopic frame can realize telescopic movement relative to the fixed frame. A plurality of second rollers 18 are provided between the driven roller 9 and the reverse roller 15, and a second plate 28 is provided between two adjacent second rollers 18. The second plate 28 and the second rollers 18 are both supported by the telescopic frame. The setting height of the second plate 28 is lower than the setting height of the first plate 27. The second rollers 18 are also circular rollers. The second plate 28 is also used to support the belt 6, and the second plate 28 is set lower than the first plate 27. In this way, when the telescopic component is contracted relative to the fixed component, the first plate 27 can move below the second plate 28. Fig.10 As shown, the telescopic movement of the telescopic part relative to the fixed part is facilitated; when the belt conveyor is in a retracted state, the reverse roller 15 is located on the inner side above the tensioning roller 14, and when the belt conveyor is in an open state, the reverse roller 15 can move to the inner side above the tensioning roller 15 (set close to the active roller).

[0046] A first fixed frame 20 is installed below the first plate, and there is a set distance between the first plate and the first fixed frame 20, so that when the telescopic component is retracted, the second plate can move to the bottom of the first plate driven by the telescopic frame. The first fixed frame 20 is supported by the fixing frame. There are multiple first fixed frames 20, and both ends of the first fixed frame 20 and both ends of the first plate are supported by the fixing frame. The first plate is a steel plate.

[0047] A second fixed frame 19 is provided below the second plate, and the second fixed frame 19 is supported by the telescopic frame. There is a set distance between the second plate and the second fixed frame 19. Both ends of the second plate are also supported by the telescopic frame. The second plate is also a steel plate, and the belt is further supported by the first fixed frame and the second fixed frame.

[0048] A telescopic mechanism is provided between the telescopic frame and the fixed frame. Figure 4 and Figure 5 As shown, the telescopic mechanism includes a rack 13 arranged on the telescopic frame and a gear 12 arranged on the fixed frame. The telescopic frame is provided with a telescopic guide rail 11. A slider is arranged on the surface of the fixed frame to cooperate with the telescopic guide rail 11. The telescopic frame and the fixed frame are both frames. The telescopic frame is arranged in the inner block of the fixed frame frame, and the height is slightly lower than that of the fixed frame. The rack 13 of the telescopic frame is arranged along the length direction of the belt conveyor body. The gear 12 is meshed with the rack 13. The gear 12 is connected to the power mechanism. The power mechanism is a telescopic motor 10. The power mechanism drives the gear to rotate, and then promotes the telescopic movement of the rack and the telescopic frame relative to the fixed frame. The gear 12 is arranged on the driven shaft, and the driven shaft is arranged along the width direction of the belt conveyor. The power mechanism is arranged on the fixed frame or the base 3. In this way, the power mechanism drives the gear 12 to rotate through the sprocket transmission mechanism, and then drives the rack 13 to move. Figure 5 The figure also shows a schematic diagram of the belt conveyor body when the telescopic component is not opened.

[0049] It should be noted that the fixed frame is provided with limit switches and mechanical stops at the two extreme positions. The limit switches are connected to the controller of the telescopic motor, so that when the telescopic frame moves to the extreme position, the action of the telescopic motor is controlled. When the limit switch fails, the mechanical stopper performs hard limit protection. Under normal circumstances, the telescopic motor 10 is provided with a control button. When the telescopic frame moves to the set position, the control button can be used to stop the telescopic frame from continuing to open.

[0050] The belt conveyor body 1 is arranged on the base 3, and a guide plate 7 is arranged at one end of the belt conveyor body 1. A lifting mechanism 2 for driving the belt conveyor body to achieve lifting is arranged between the belt conveyor body 1 and the base 3. Figure 8 and Fig. 9As shown, the lifting mechanism 2 is supported by a lifting bracket, and the lifting bracket includes a lower lifting bracket 26 and an upper lifting bracket 25. The upper lifting bracket 25 is connected to the fixed frame, and the lower lifting bracket 26 is fixedly connected to the base 3. The lifting mechanism is a lift 24, and the lifting rod of the lift passes through the lower lifting bracket 26 and is connected to the upper lifting bracket 25. The lift is a hydraulic lifting mechanism, a pneumatic lifting mechanism, or an electric lifting mechanism. A guide shaft 23 is provided between the upper lifting bracket 25 and the lower lifting bracket 26. The guide shaft 23 passes through the lower lifting bracket 26, and the bottom of the guide shaft 23 is fixedly connected to the base. The guide shaft 23 is provided on both sides of the lift. In this way, during the lifting process of the lift, the guide shaft 23 plays a guiding role. The lift 24 is lifted and lowered, and the lifting and lowering movement of the belt conveyor body 1 is driven by the upper lifting bracket 25.

[0051] Among them, the lifting mechanism is arranged at one side each on the front and rear sides of the belt conveyor base, so that the front or rear of the belt conveyor can be lifted and lowered separately according to work requirements. In order to achieve smooth lifting on one side, the upper lifting bracket in the lifting mechanism on one side is hingedly connected to one side of the fixed frame, and the upper lifting bracket in the lifting mechanism on the other side is floatingly hingedly connected to the other side of the fixed frame. The floating hinged connection uses a connecting shaft floatingly arranged in a fixed frame, the connecting shaft is installed on the upper lifting bracket, and the fixed frame is arranged on the fixed frame.

[0052] The base 3 is frame-shaped, such as Figure 6 and Figure 7 As shown, a baffle can be set on the surrounding side of the base, and a lateral moving force member is installed on the base. The lateral moving force member is preferably a lateral shift motor 21. The lateral moving force member is connected to the lateral shift transmission shaft 22. The lateral shift transmission shaft 22 is set along the length direction of the belt conveyor body 1, and the lateral shift transmission shaft is set on one side of the base 3. In order to ensure the stable movement of the base 3, the base 3 is also provided with a second shaft parallel to the lateral shift transmission shaft. The two ends of the lateral shift transmission shaft are respectively connected to the lateral shift wheels, and driven wheels are set at both ends of the second shaft. The lowest points of the lateral shift wheels and the driven wheels are set lower than the lower surface of the base. The lateral shift wheel is perpendicular to the lateral shift transmission shaft 22. When the belt conveyor is set on the ground, the lateral shift wheel can contact the ground, and the lateral shift force member drives the lateral shift transmission shaft to rotate, thereby driving the lateral shift wheel to roll relative to the ground, thereby driving the entire belt conveyor to move lateral.

[0053] A folding platform 5 is provided on the side of the base 3, and the folding platform 5 can be rotated relative to the base, so that the staff can stand on the surface of the folding platform to work, and the folding platform 5 can be folded up when not needed; one end of the folding platform is connected to the base 3 through a rotating shaft that can be rotated 90 degrees, and a slot is provided on the side of the base 3. The shape of the slot is consistent with the shape of the folding platform, which is used to accommodate the folding platform 5. When the folding platform is not in use, the folding platform is rotated and put away. When needed, the folding platform is rotated and lowered, so that quality inspectors can work on the platform during the conveying process of the belt conveyor.

[0054] In addition, the active motor, the lift, the side shift motor and the telescopic motor are all connected to the controller, and the controller is a PLC programmable controller. The controller is arranged in the base and can be arranged on the inner side of the card slot.

[0055] The entire stamping belt conveyor can realize sideways movement through the setting of the side-shift wheel, and the setting of the lifting mechanism can realize the lifting of the belt conveyor body. The height of the belt conveyor body can be adjusted according to the height of the object to be conveyed to meet the blanking height and packing height of different parts. In addition, through the setting of telescopic parts and fixed parts, the movement of the telescopic parts relative to the fixed parts can be realized, thereby extending the length of the belt conveyor body, and the belt is effectively supported in the belt conveyor body to ensure the flatness of the belt setting. The entire stamping belt conveyor can better meet the different needs of the stamping production line.
