Description

Technical Field

[0001] The utility model belongs to the technical field of high-level-difference conveying of workpieces, and in particular relates to a workpiece transfer device for a high-level-difference conveying line. Background Art

[0002] During the processing of metal workpieces, multiple processing steps are often required. Conveyor belts are typically used to transport metal parts from a first processing device to a second processing device for continuous processing. There is sometimes a significant height difference between the discharge port of the first processing device and the feed port of the second processing device. Furthermore, to ensure continuous processing of the workpiece and save processing equipment space and costs, it is inconvenient to move the first and second processing devices.

[0003] In the prior art, metal workpieces are conveyed using inclined conveyor belts. However, when the conveyor belt is tilted, the friction between the metal workpiece and the belt is insufficient to support the workpiece's elevation or lowering. This can easily cause the workpiece to slip, causing it to fall off the belt and severely impacting conveying efficiency. Furthermore, the greater the height difference between the discharge port of the first processing equipment and the feed port of the second processing equipment, the more likely the metal workpiece is to fall off. Utility Model Content

[0004] To address the aforementioned shortcomings, the present invention provides a workpiece transfer device for high-height differential conveyor lines. By disposing a transfer mechanism between a first conveyor belt and a second conveyor belt, the device can raise or lower the height of a metal workpiece. A transfer mechanism of appropriate height is employed, depending on actual needs, to overcome the height differential between the first and second processing equipment. An electromagnet is installed within the transfer mechanism's transfer box, along with an induction switch, to prevent the metal workpiece from accidentally escaping from the box.

[0005] The utility model is realized through the following technical solutions:

[0006] A workpiece transfer device for a high-level difference conveyor line includes a first conveyor belt, a second conveyor belt, and a transfer mechanism. The first conveyor belt is connected to the discharge port of the first processing equipment; the second conveyor belt is connected to the feed port of the second processing equipment. The conveying direction of the second conveyor belt is consistent with the conveying direction of the first conveyor belt, and there is a height difference between the second conveyor belt and the first conveyor belt; the transfer mechanism is located between the first conveyor belt and the second conveyor belt to transfer the metal workpiece on the first conveyor belt to the second conveyor belt. The transfer mechanism includes a vertically arranged support frame, a driving wheel and a driven wheel mounted to the support frame, a conveying chain mounted between the driving wheel and the driven wheel, and a transfer box. Two groups of conveying chains are arranged in parallel, and a number of transfer boxes are provided between the two groups of conveying chains to realize the carrying and transfer of metal workpieces. An electromagnet and an induction switch connected to the electromagnet are installed at the bottom of each transfer box. A power-on controller is installed at the support frame near the first conveyor belt, and a power-off controller is installed at the support frame near the second conveyor belt. Both the power-on controller and the power-off controller are connected to the induction switch signal. The metal workpiece in the transfer process is adsorbed by the electromagnet, and the metal workpiece in the transfer box is separated from the transfer box.

[0007] Furthermore, the transfer box is open on one side and the opening direction points to the side away from the conveyor chain. The bottom of the transfer box is installed to the conveyor chain through an L-shaped frame, and the electromagnet is embedded in the bottom of the transfer box to ensure the flatness of the inside of the transfer box.

[0008] Furthermore, a through hole is provided on the L-shaped frame, and a threaded hole aligned with the through hole is provided on the bottom of the transfer box. The transfer box and the L-shaped frame are fixedly connected by bolts, which facilitates disassembly, assembly and maintenance of the transfer box.

[0009] Furthermore, the control distances of the power-on controller and the power-off controller are equal, and the control distances are greater than the shortest distance between the power-on controller and the induction switch, so as to ensure that the power-on controller and the power-off controller control the induction switch.

[0010] Furthermore, the driving wheel is mounted on the top of the support frame and is flush with the second conveyor belt, the driven wheel is mounted on the support frame and is located directly below the driving wheel, and the driven wheel is flush with the first conveyor belt.

[0011] Furthermore, the driving wheel and the driven wheel are meshed with the conveying chain, and an electric motor for driving the driving wheel to rotate is installed on the top of the support frame to provide power support for the rotation of the driving wheel.

[0012] Furthermore, a material unloading baffle is installed on the side of the first conveyor belt close to the transfer mechanism, and the inclination angle of the material unloading baffle relative to the first conveyor belt is adjustable to facilitate the flow of metal workpieces on the first conveyor belt into the transfer box. A material receiving baffle is installed on the side of the second conveyor belt close to the transfer mechanism to facilitate the movement of metal workpieces in the transfer box to the second conveyor belt.

[0013] Furthermore, a counter is installed on the power-off controller, and the counter can count the transfer boxes passing through the power-off controller, thereby realizing the counting of the transported metal workpieces.

[0014] Furthermore, the support frame is provided with evenly distributed positioning holes in the vertical direction, and the driving wheel and the driven wheel are both mounted to the positioning holes by bolts, and the position of the driving wheel relative to the support frame is adjustable, and the position of the driven wheel relative to the support frame is adjustable to adapt to the first conveyor belt and the second conveyor belt of various heights.

[0033] like Figures 1 to 6The workpiece transfer device of a high-level difference conveyor line shown in the figure includes a first conveyor belt 1, a second conveyor belt 2 and a transfer mechanism 3. The first conveyor belt 1 is connected to the discharge port of the first processing equipment; the second conveyor belt 2 is connected to the feed port of the second processing equipment. The conveying direction of the second conveyor belt 2 is consistent with the conveying direction of the first conveyor belt 1, and there is a height difference between the second conveyor belt 2 and the first conveyor belt 1; the transfer mechanism 3 is located between the first conveyor belt 1 and the second conveyor belt 2 to transfer the metal workpiece on the first conveyor belt 1 to the second conveyor belt 2. The transfer mechanism 3 includes a vertically arranged support frame 31, a driving wheel 32 and a driven wheel 33 installed on the support frame 31, a conveying chain 34 installed between the driving wheel 32 and the driven wheel 33, and a transfer box 35. There are two groups of conveying chains 34 arranged in parallel, and a number of transfer boxes 35 are provided between the two groups of conveying chains 34 to realize the carrying and transfer of metal workpieces. An electromagnet 351 and an induction switch 352 connected to the electromagnet 351 are installed at the bottom of each transfer box 35. A power-on controller 36 is installed on the support frame 31 near the first conveyor belt 1, and a power-off controller 37 is installed on the support frame 31 near the second conveyor belt 2. The power-on controller 36 and the power-off controller 37 are both connected to the signal of the induction switch 352. The metal workpiece in the transfer process is adsorbed by the electromagnet 351, and the metal workpiece in the transfer box 35 is separated from the transfer box 35.

[0034] In one embodiment, after the first processing equipment completes processing on a metal workpiece, the workpiece falls from the discharge port of the first processing equipment onto the first conveyor belt 1. The first conveyor belt 1 transfers the workpiece to the transfer box 35 of the transfer mechanism 3. Simultaneously, the power-on controller 36 issues an on command to the sensor switch 352 of the transfer mechanism 3. The sensor switch 352 energizes the electromagnet 351, which securely holds the metal workpiece within the transfer box 35. The motor 321 then rotates the conveyor chain 34 via the drive wheel 32, causing the conveyor chain 34 on the side closest to the first conveyor belt 1 to move upward, thereby driving the transfer box 35, which is secured to the conveyor chain 34, to move vertically upward. When the transfer box 35 reaches the top of the conveyor chain 34, the power-off controller 37 issues a off command to the sensor switch 352, which de-energizes the electromagnet 351, releasing its grip on the workpiece. At this point, the opening of the transfer box 35 is now pointing vertically upward. The driving wheel 32 continues to drive the transfer box 35 to move through the conveyor chain 34. The opening of the transfer box 35 gradually points to the second conveyor belt 2, and the metal workpiece falls from the transfer box 35 to the second conveyor belt 2. The second conveyor belt 2 transports the metal workpiece to the second processing equipment for further processing of the metal workpiece.

[0035] In one embodiment, both side panels of the transfer box 35 are tilted relative to the bottom panel. The side panels of the transfer box 35 located on the side close to the first conveyor belt 1 are tilted upward to prevent metal workpieces that have fallen into the transfer box 35 from escaping from the transfer box 35. The side panels of the transfer box 35 located on the side close to the second conveyor belt 2 are tilted downward to facilitate the metal workpieces in the transfer box 35 to fall onto the second conveyor belt 2.

[0036] Preferably, the transfer box 35 is open on one side and the opening direction points to the side away from the conveying chain 34. The bottom of the transfer box 35 is installed to the conveying chain 34 through an L-shaped frame 38, and the electromagnet 351 is embedded in the bottom of the transfer box 35 to ensure the flatness of the inside of the transfer box 35.

[0037] Preferably, a through hole 381 is provided on the L-shaped frame 38, and a threaded hole 353 aligned with the through hole 381 is provided on the bottom of the transfer box 35. The transfer box 35 and the L-shaped frame 38 are fixedly connected by bolts, which facilitates the disassembly, assembly and maintenance of the transfer box 35.

[0038] In one embodiment, during long-term conveying operations, metal workpieces may collide with the transfer box 35, easily causing damage to the transfer box 35. The transfer box 35 is fixedly connected to the L-shaped frame 38 by bolts, which facilitates the replacement and repair of damaged transfer boxes 35, ensuring the continuous operation of the transfer device.

[0039] Preferably, the control distances of the power-on controller 36 and the power-off controller 37 are equal, and the control distances are greater than the shortest distance between the power-on controller 36 and the sensing switch 352 , so as to ensure that the power-on controller 36 and the power-off controller 37 control the sensing switch 352 .

[0040] It should be noted that when the transfer device is running, the power-on controller 36 and the power-off controller 37 can only control the induction switch 352 of one transfer box 35 at the same time.

[0041] Preferably, the driving wheel 32 is mounted to the top of the support frame 31 and is flush with the second conveyor belt 2 , and the driven wheel 33 is mounted to the support frame 31 and is located directly below the driving wheel 32 , and the driven wheel 33 is flush with the first conveyor belt 1 .

[0042] Preferably, the driving wheel 32 and the driven wheel 33 are meshed with the conveying chain 34 , and a motor 321 for driving the driving wheel 32 to rotate is installed on the top of the support frame 31 to provide power support for the rotation of the driving wheel 32 .

[0043] Preferably, a material unloading baffle 11 is provided on the side of the first conveyor belt 1 close to the transfer mechanism 3. The inclination angle of the material unloading baffle 11 relative to the first conveyor belt 1 is adjustable to facilitate the flow of metal workpieces on the first conveyor belt 1 into the transfer box 35. A material receiving baffle 21 is provided on the side of the second conveyor belt 2 close to the transfer mechanism 3 to facilitate the movement of metal workpieces in the transfer box 35 to the second conveyor belt 2.

[0044] In one embodiment, the shortest distance between the unloading baffle 11 and the transfer box 35 is smaller than the outer diameter of the metal workpiece, and the shortest distance between the receiving baffle 21 and the transfer box 35 is smaller than the outer diameter of the metal workpiece, so as to prevent the metal workpiece from escaping to the outside when entering the transfer mechanism 3 or flowing out of the transfer mechanism 3.

[0045] Preferably, a counter 39 is also installed on the power-off controller 37. The counter 39 can count the transfer boxes 35 passing through the power-off controller 37, thereby counting the transported metal workpieces.

[0046] Preferably, the support frame 31 is provided with evenly distributed positioning holes in the vertical direction, and the driving wheel 32 and the driven wheel 33 are both mounted to the positioning holes by bolts, and the position of the driving wheel 32 relative to the support frame 31 is adjustable, and the position of the driven wheel 33 relative to the support frame 31 is adjustable to adapt to the first conveyor belt 1 and the second conveyor belt 2 of various heights.

[0047] Preferably, the interior of the transfer box 35 is coated with a Teflon coating. The surface of the Teflon coating has low friction and good wear resistance. By providing the Teflon coating inside the transfer box 35, it helps to reduce the wear of the transfer box 35 when the metal workpiece collides with the transfer box 35, thereby increasing the service life of the transfer box 35.

[0048] When using the workpiece transfer device for a high-level differential conveyor line described above, a transfer mechanism 3 is positioned between the first conveyor belt 1 and the second conveyor belt 2 to raise or lower the metal workpiece. Depending on actual needs, the transfer mechanism 3 is designed at an appropriate height to overcome the height difference between the first and second processing equipment. An electromagnet 351 is installed within the transfer box 35 of the transfer mechanism 3, along with an induction switch 352, to prevent the metal workpiece from accidentally escaping from the box.
