Description

Technical Field

[0001] This invention belongs to the field of transportation and material feeding, specifically a fishtail plate production feeding device. Background Technology

[0002] The main raw material for fishplate production is metal sheet. During the fishplate production process, in order to facilitate installation and fixation of the fishplate, and to ensure the structural stability and strength of the fishplate, it is usually necessary to drill holes in the metal sheet. Furthermore, since each step of fishplate production requires specific equipment and customized operations based on the needs of each type of fishplate, a separate feeding operation is required when punching holes in the metal sheet.

[0003] A patent application with publication number CN104150238A discloses an automatic feeding device using a pulley-driven flip-plate. The device includes a ladder, uprights, a flip-plate for loading materials, and a tray for supporting the flip-plate. A fixed pulley is located on the upper part of the back of the ladder, and a movable pulley is fixedly connected below the tray. The movable pulley allows the flip-plate to slide on the surface of the ladder. This device has a simple structure, small footprint, is easy to operate, and has a wide range of applications. A baffle is installed at the top of the ladder, with a spring below it. When the flip-plate moves and touches the baffle, it automatically tilts and compresses the baffle to unload the material, thus ensuring the automatic feeding device returns to its original position after unloading.

[0004] The above solution still has some problems in practical application. This automatic feeding device uses the reciprocating motion and flipping of the pallet to feed the material in a cycle. However, the feeding method is the traditional "tilting". This feeding method not only cannot arrange the transported objects neatly, but also cannot accurately position the objects according to their specific conditions. As a result, subsequent transfers require separate adjustments, which is very cumbersome.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1

[0035] like Figures 1 to 10 As shown, an embodiment of the fishtail plate production feeding device of the present invention includes a base frame 1, a slide rail 2 at the upper end of the base frame 1, an inclined surface on the left side of the upper end of the base frame 1, and a tray 3 sliding on the inclined surface of the base frame 1. Both sides of the tray 3 are rotatably connected to pulleys 4, which slide on the inner wall of the slide rail 2. A switch 9 is provided on the side of the base frame 1 to control the rotation of the pulleys 4. A top plate 8 is provided on the right side of the upper end of the base frame 1, and a transfer device 5 is provided on the right side of the top plate 8. The transfer device 5 includes a conveying roller 51, which is rotatably connected to the right side of the top plate 8, and the conveying roller 51 is positioned relative to the top plate 8. On the same horizontal line; positioning clamps 52, two positioning clamps 52 are located on the upper end of the conveying roller 51, and the two positioning clamps 52 move towards each other; first conveying track 55, the first conveying track 55 is located on the right side of the conveying roller 51; the fishtail plate production feeding device is used to convey metal plates to the punching equipment 7, the punching equipment 7 processes the metal plates into fishtail plates, the punching equipment 7 includes: an operation plate 72 and a punching block 75 set on the placement platform 71 for punching work, the operation plate 72 is rotatably mounted on the upper end of the placement platform 71 through a rotating shaft 74 for pushing the telescopic rod 76 of the operation plate 72.

[0036] Specifically, the main raw material for fishplate production is metal sheet. In the fishplate production process, in order to facilitate the installation and fixing of the fishplate, as well as to ensure the structural stability and strength of the fishplate, it is usually necessary to drill holes in the metal sheet. Before drilling, the metal sheet needs to be cut, trimmed and surface treated. Moreover, each step of fishplate production requires specific equipment and customized operations according to the needs of each type of fishplate. Therefore, the entire production process cannot be completed entirely by a single assembly line. This necessitates a separate, cumbersome feeding operation when punching metal sheets. To address this, a feeding device is installed. The tray 3 above the base frame 1 receives the surface-treated metal sheets, which is the step preceding the punching process. During surface treatment, the metal sheets are typically conveyed by a conveyor belt. After surface treatment, the metal sheets are fed onto the surface of the tray 3 via the tail of the conveyor belt. The surface area of ​​the tray 3 is much larger than that of the metal sheets. At this point, switch 9 is activated, causing pulley 4 to rotate. This pulley 4 then moves the tray 3 and the metal sheets on its surface towards the top plate 8. Once the metal sheets reach the top plate 8... The metal sheet will fall onto the surface of the conveyor roller 51. Because the portion of the conveyor roller 51 near the top plate 8 is densely packed, the metal sheet will not fall between the two conveyor rollers 51 when it lands on the surface. At this point, switch 9 is activated again, causing pulley 4 to reverse, thus moving tray 3 away from the top plate 8. It eventually moves back to the area below the metal sheet surface treatment device. When the metal sheet lands on the surface of the conveyor roller 51, the conveyor roller 51 is activated to rotate. The conveyor roller 51 will rotate the metal sheet on its surface. Simultaneously, the positioning clamps 52 are activated, and the two positioning clamps 52 will move closer to each other, as shown in the attached figure. Figure 4The positioning clamp 52 shown ultimately adjusts the position of the metal sheet on the surface of the conveying roller 51 to a vertical position, so that the length of the metal sheet fits against the inner wall of the positioning clamp 52, and the width of the metal sheet corresponds to the position of the first conveying track 55, thus aligning the position of the metal sheet with the position of the first conveying track 55. This allows the metal sheet to be delivered to the surface of the first conveying track 55. The first conveying track 55 is then restarted to transport the metal sheet to the surface of the operating plate 72. The hydraulic cylinder 77 is activated to move the punching block 75 towards the surface of the metal sheet, ultimately punching the metal sheet to form a fishtail plate. A telescopic rod 76 is installed on the lower surface of the operating plate 72. When the metal sheet has been punched and formed into a fishtail plate, the telescopic rod 76 is activated to abut against the operating plate 72. Since the operating plate 72 is initially horizontal, when the telescopic rod 76 is activated, the operating plate 72 will tilt around the rotation axis 74, as shown in the attached diagram. Figure 10 When the operating panel 72 is in the indicated state, the fishtail plate located on the upper surface of the operating panel 72 will be automatically unloaded. After the fishtail plate on the upper surface of the operating panel 72 is unloaded, the telescopic rod 76 is activated again to drive the operating panel 72 back to its original position, so as to perform punching operation on the next metal sheet. By setting up the transfer device 5, after the metal sheet has been surface treated, it can be automatically moved to the inside of the punching equipment 7 for punching, without the need to adjust the position of the fishtail plate before punching, which is very convenient.

[0037] like Figures 1 to 10 As shown, the transfer device 5 also includes: a telescopic cylinder 53, which is located below the conveying roller 51 and is fixedly connected to the positioning clamping plate 52; a conveying frame 54, which is located on the right side of the top plate 8 and has a first conveying track 55 inside; a second conveying track 56, which is located on the left side of the operating plate 72 and is at the same horizontal level as the operating plate 72; the punching device 7 also includes: a hole groove 73 opened on the surface of the operating plate 72, and a hydraulic cylinder 77 for controlling the up and down movement of the punching block 75.

[0038] Specifically, when the metal sheet moves to the surface of the conveying roller 51, the telescopic cylinder 53 is activated at the same time as the conveying roller 51 is started to rotate. This causes the telescopic cylinder 53 to move the positioning clamp 52. The metal sheet, after being positioned, is then moved to the surface of the first conveying track 55. The first conveying track 55 then transfers the metal sheet to the second conveying track 56. Since the second conveying track 56 and the operating plate 72 are on the same horizontal line, the metal sheet can be smoothly conveyed to the surface of the operating plate 72 for punching, and finally processed into a fishtail plate.

[0039] like Figure 6 As shown, the surface of the second conveyor belt 56 is provided with a number of snap fasteners 57, which are arranged in pairs, and metal plates are placed between each pair of snap fasteners 57.

[0040] Specifically, when the metal sheet moves to the surface of the second conveyor belt 56, the second conveyor belt 56 needs to be started to rotate and move the metal sheet to the surface of the operating plate 72. In order to ensure that the metal sheet can fall accurately onto the surface of the operating plate 72, several snap fasteners 57 are set on the surface of the second conveyor belt 56. The metal sheet will fall between two snap fasteners 57 and be fixed, and then be sent to the surface of the operating plate 72. This avoids the problem that the metal sheet does not move accurately to the surface of the operating plate 72 when the second conveyor belt 56 is transferring the metal sheet.

[0041] like Figures 3 to 4 As shown, the front end of the conveying rollers 51 is densely arranged near the top plate 8, so that the gap between the two conveying rollers 51 is smaller than the thickness of the metal plate, and the height of the conveying rollers 51 is slightly higher than the top plate 8.

[0042] Specifically, since the pallet 3 uses a tilting method to deliver the metal sheet to the conveying roller 51, the height of the conveying roller 51 is set to be slightly higher than the top plate 8, and the conveying rollers 51 near the top plate 8 are densely arranged. This not only prevents the metal sheet from falling into the gap between the two conveying rollers 51, but also reduces the damage to the metal sheet when tilting by lowering the height of the tilting.

[0043] like Figures 4 to 9 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a detection platform 10 is provided on the right side of the top plate 8, and a detection device 6 is provided on the upper surface of the detection platform 10; the detection device 6 includes: a detection frame 601, which is disposed on the surface of the detection platform 10 near one end of the first conveyor belt 55, the interior of the detection frame 601 is used to place metal plates, one end of the detection frame 601 is provided with the first conveyor belt 55, and the other end of the detection frame 601 is provided with the second conveyor belt 56; and a connecting arm 608, which is rotatably connected to the detection platform. The surface of the detection platform 10 is fixedly connected to the arc surface of the connecting arm 608; the irradiation hole 605 is opened at the bottom of the detection frame 601; the detector 604 is located inside the detection platform 10 and below the irradiation hole 605, and the detector 604 is connected to the connecting arm 608; the abutment post 607 is slidably connected to the upper end of the detection platform 10; the placement shaft 613 is rotatably connected to the upper end of the detection platform 10 near the end of the second conveyor belt 56.

[0044] Specifically, when the metal plate is on the surface of the first conveyor belt 55, it will move through the first conveyor belt 55 to the inside of the detection frame 601. At this time, the detector 604 located at the lower end of the irradiation hole 605 is activated. This detector 604 is a laser height measuring instrument. The detector 604 emits a laser beam, which irradiates the bottom of the metal plate inside the detection frame 601. Then, the receiver inside the detector 604 receives the reflected laser beam. By measuring the time difference between the emission and reception of the laser beam and using the speed of light, the distance to the target object can be calculated. If the smooth side of the metal plate inside the detection frame 601 is facing down, the distance between the detector 604 and the bottom of the metal plate is the normal distance. The detection frame 601 will then detect the metal plate inside. The sheet metal is conveyed to the surface of the second conveyor belt 56, and then transported by the second conveyor belt 56 to the surface of the operating plate 72 for punching, ultimately processing it into a fishtail plate. If the smooth side of the sheet metal inside the detection frame 601 is facing upwards, the distance between the detector 604 and the bottom of the sheet metal will increase. The detector 604 considers this an abnormal distance and sends a signal to the connecting arm 608. The connecting arm 608 receives the signal from the detector 604 and rotates. The detection frame 601, which is fixedly connected to the connecting arm 608, will also be driven, thereby flipping the detection frame 601 and the sheet metal inside the detection frame 601 180°, so that the sheet metal is placed with the smooth side facing downwards, as shown in the attached figure. Figure 6 As shown in the detection frame 601, the abutment column 607 is activated, and the abutment column 607 will extend and retract at the upper end of the detection platform 10, thereby pushing the metal plate inside the detection frame 601 to the placement shaft 613 for placement. Then, the flipped metal plate is picked up and transported to the surface of the second conveyor belt 56. By setting the detection device 6, the placement orientation of the metal plate transported to the detection frame 601 can be detected. If the smooth surface of the metal plate is placed upward, when the punching block 75 punches the metal plate, although the punching will be completed, the contact area between the metal plate and the operating plate 72 will be smaller, and the impact force of the punching block 75 on the metal plate will be greater, which will make the metal plate easily damaged. Therefore, when it is detected that the smooth surface of the metal plate is placed upward, the smooth surface of the metal plate will be placed downward by rotating the connecting arm 608, and then the punching operation will be performed.

[0045] like Figures 4 to 9 As shown, the detection device 6 also includes: a threaded sleeve 612, which is located at the end of the detection platform 10 away from the detection frame 601; a telescopic column 606, which is fixedly connected to one end of the abutment column 607; and a fixing screw 611, which is located at one end of the telescopic column 606 and is threadedly connected to the threaded sleeve 612.

[0046] Specifically, when the detector 604 detects that the smooth side of the metal plate is facing upwards, it will start the connecting arm 608 to rotate. During the rotation of the connecting arm 608, the fixing screw 611 will also be started to rotate. Since the fixing screw 611 is engaged with the threaded sleeve 612, the fixing screw 611 will not drive the abutment post 607 to rotate, but will drive the abutment post 607 to perform telescopic movement, thereby pushing the metal plate located inside the detection frame 601 onto the surface of the placement shaft 613.

[0047] like Figures 6 to 9 As shown, a tilting shaft 614 is fixedly connected to one end of the detection platform 10 near the second conveyor belt 56. Several steering rollers 615 are provided at the lower end of the placement shaft 613, and the several steering rollers 615 rotate on the arc surface of the tilting shaft 614.

[0048] Specifically, when the metal sheet falls onto the surface of the placement shaft 613, the steering roller 615 located at the lower end of the placement shaft 613 is activated. The steering roller 615 tilts around the tilting shaft 614 as the center, thereby sending the metal sheet on the surface of the placement shaft 613 to the surface of the steering roller 615. Subsequently, due to the influence of gravity, the metal sheet will move from the surface of the steering roller 615 to the surface of the second conveyor belt 56, thus automatically moving the metal sheet from the surface of the placement shaft 613 to the surface of the second conveyor belt 56.

[0049] like Figures 5 to 6 As shown, an auxiliary gear 610 is provided between the telescopic column 606 and the fixed screw 611, and a connecting gear 609 is provided at the end of the connecting arm 608 away from the steering roller 615. The connecting gear 609 meshes with the auxiliary gear 610.

[0050] Specifically, when the connecting arm 608 rotates, the connecting gear 609 drives the auxiliary gear 610 to rotate, which in turn drives the fixing screw 611 to rotate. Then, as the fixing screw 611 rotates, the abutment post 607 will extend and retract, pushing the metal plate inside the detection frame 601 to the surface of the placement shaft 613. By setting the auxiliary gear 610 and the connecting gear 609, the rotation of the detection frame 601 and the movement of the abutment post 607 can be coordinated, which not only reduces energy consumption but also makes the cooperation between the detection frame 601 and the abutment post 607 more precise.

[0051] like Figures 5 to 6 As shown, the detection frame 601 has several auxiliary rollers 602 rotatably connected inside, and the auxiliary rollers 602 are in contact with the metal plate.

[0052] Specifically, by setting up an auxiliary roller 602, when the metal sheet is conveyed from the first conveyor belt 55 to the inside of the detection frame 601, the auxiliary roller 602 is started to rotate, and the metal sheet will come into contact with the surface of the auxiliary roller 602, thereby driving the metal sheet to rotate faster.

[0053] like Figures 5 to 6 As shown, the upper right side of the detection frame 601 is provided with a positioning buckle 603, which abuts against the metal plate and is made of rubber.

[0054] Specifically, when the metal sheet is conveyed into the interior of the detection frame 601, if the smooth surface of the metal sheet is facing upwards, the metal sheet will abut against the positioning buckle 603, thereby preventing the metal sheet from moving directly to the surface of the second conveyor belt 56. It can only be transferred again by pushing the abutment column 607.

[0055] Working Principle: The tray 3 above the base frame 1 is positioned below the metal sheet surface treatment device. Surface treatment is the step before punching the metal sheet. After the metal sheet surface treatment is completed, it will fall onto the surface of the tray 3. At this time, the switch 9 is activated, causing the pulley 4 to rotate. This pulley 4 moves the tray 3 and the metal sheet on its surface towards the top plate 8. When the metal sheet reaches the top plate 8, it will fall onto the surface of the conveyor roller 51. The switch 9 is then activated again, causing the pulley 4 to reverse, thus moving the tray 3 away from the top plate 8. Finally, it moves back to the area below the metal sheet surface treatment device. When the metal sheet falls onto the surface of the conveyor roller 51, the conveyor roller 51 is activated to rotate. The conveyor roller 51 will rotate the surface metal sheet. Simultaneously with the rotation of the conveyor roller 51, the positioning clamps 52 are activated. The two positioning clamps 52 will move towards each other, and their positions after movement are shown in the attached figure. Figure 4The positioning clamp 52 shown ultimately adjusts the position of the metal plate on the surface of the conveyor roller 51 so that the position of the metal plate corresponds to the position of the first conveyor belt 55, thereby sending the metal plate to the surface of the first conveyor belt 55. The first conveyor belt 55 is restarted to transport the metal plate into the interior of the detection frame 601. At this time, the detector 604 located at the lower end of the irradiation hole 605 is activated. This detector 604 is a laser height measuring instrument. The detector 604 emits a laser beam, which irradiates the bottom of the metal plate inside the detection frame 601. Then, the receiver inside the detector 604 receives the reflected laser beam. By measuring the time difference between the emission and reception of the laser beam and using the speed of light, the distance to the target object can be calculated. If the smooth side of the metal plate inside the detection frame 601 is facing down at this time, the detector 604... 4. When the distance between the detector 604 and the bottom of the metal plate is normal, the detector 601 will transport the internal metal plate to the surface of the second conveyor belt 56, and then the second conveyor belt 56 will transport the metal plate to the surface of the operating plate 72 for punching, ultimately processing it into a fishtail plate. If the smooth side of the metal plate inside the detector 601 is facing upwards, the distance between the detector 604 and the bottom of the metal plate will increase. The detector 604 will consider this an abnormal distance and transmit a signal to the connecting arm 608. The connecting arm 608 will receive the signal from the detector 604 and rotate. The detector 601, which is fixedly connected to the connecting arm 608, will also be driven, thereby flipping the detector 601 and the metal plate inside the detector 601 180°, so that the metal plate is placed with the smooth side facing down, as shown in the attached diagram. Figure 6As shown in the detection frame 601, the abutment column 607 is activated, and the abutment column 607 will extend and retract at the upper end of the detection platform 10, thereby pushing the metal plate located inside the detection frame 601 to the placement shaft 613 for placement. When the metal plate lands on the surface of the placement shaft 613, the steering roller 615 located at the lower end of the placement shaft 613 is activated. The steering roller 615 will tilt around the tilting shaft 614 as the center, thereby sending the metal plate located on the surface of the placement shaft 613 to the surface of the steering roller 615. Subsequently, due to the influence of gravity, the metal plate will move from the surface of the steering roller 615 to the second conveyor belt 5. The surface of the second conveyor belt 56 is automatically moved from the surface of the placement shaft 613 to the surface of the second conveyor belt 56. Since the second conveyor belt 56 and the operating plate 72 are on the same horizontal line, the metal sheet can be smoothly conveyed to the surface of the operating plate 72. The hydraulic cylinder 77 is activated to drive the punching block 75 to move towards the surface of the metal sheet, and finally punching the metal sheet to process it into a fishtail plate. By setting the transfer device 5, after the metal sheet has been surface treated, it will be automatically moved to the inside of the punching equipment 7 for punching without the need for adjustment and separate collection, which is very convenient.
