Technical Field

[0001] This application relates to a material conveying device, and more particularly to a material conveying device for conveying pallets and products on pallets. Background Technology

[0002] In existing product processing and manufacturing processes, materials are typically transported on pallets. Pallets effectively protect the materials and prevent damage during transport. Loading involves transferring the pallets loaded with materials to the product assembly line, removing the materials from the pallets, and finally removing the empty pallets. However, many loading steps are performed manually, resulting in low efficiency and failing to meet the requirements for high-volume, high-efficiency loading. Summary of the Invention

[0003] In view of this, this application provides a material conveying device, comprising:

[0004] A conveying module includes a conveyor belt and a lifting mechanism. The conveyor belt is used to drive a pallet to move horizontally in one direction, and the lifting mechanism is used to lift the pallet on the conveyor belt.

[0005] A feeding module, movably disposed at the starting end of the conveyor belt, is used to place the pallet and transfer the pallet onto the conveyor belt; and

[0006] The clamping and moving module, located above the conveyor belt, includes a drive mechanism, a slide rail, and a clamping mechanism slidably mounted on the slide rail. The clamping mechanism is used to clamp a tray that is lifted by the lifting mechanism, and the drive mechanism is used to drive the clamping mechanism to slide back and forth along the slide rail.

[0007] The material conveying device of this application, through the cooperation of a feeding module, a conveying module, and a clamping and moving module, loads multiple pallets into the feeding module and transfers them onto a rotating conveyor belt. Then, a lifting mechanism lifts the multiple pallets, and a clamping mechanism clamps the top pallet lifted by the lifting mechanism. After removing the material from the pallet, the clamping mechanism continues to clamp the empty pallet and moves it to remove the empty pallet. In this way, the material carried by the pallets can be automatically fed and the empty pallets can be mechanically transferred, which can meet the requirements of large-volume and high-efficiency feeding and effectively improve production efficiency.

[0061] This application provides a material conveying device that can automatically load materials onto pallets and mechanically transfer empty pallets.

[0062] like Figure 1 and Figure 2As shown, the material conveying device 100 of this application embodiment includes a feeding module 10, a conveying module 30, and a clamping and moving module 50. A pallet (not shown) carrying materials passes sequentially through the feeding module 10, the conveying module 30, and the clamping and moving module 50, whereby the materials are transferred, and empty pallets are collected. In this application embodiment, the pallets are rectangular, and each pallet can hold multiple materials.

[0063] Please refer to the following: Figure 1 and Figure 2 The conveying module 30 includes a conveyor belt 31 and a lifting mechanism 33. The conveyor belt 31 drives the pallet to move horizontally in one direction. The lifting mechanism 33 is located at the end of the conveyor belt 31 and is used to lift the pallet on the conveyor belt 31 longitudinally to the material picking area (the area where the clamping and moving module 50 is located).

[0064] Please refer to the following: Figure 1 and Figure 2 The loading module 10 is used to place multiple pallets, which are stacked longitudinally. The loading module 10 is located at the starting end of the conveyor belt 31 and is movable relative to the conveyor belt 31. The loading module 10 moves away from the conveyor belt 31 to place multiple pallets loaded with materials into the loading module 10, and then the loading module 10 with the material-loaded pallets moves closer to the conveyor belt 31 to transfer the multiple pallets onto the conveyor belt 31.

[0065] Please see Figure 1 and Figure 2 The clamping and moving module 50 is located above the conveyor belt 31 along its longitudinal direction and includes a slide rail 51, a clamping mechanism 53 slidably mounted on the slide rail 51, and a drive mechanism 55. The clamping mechanism 53 is used to clamp the topmost pallet among the pallets lifted by the lifting mechanism 33. The drive mechanism 55 is used to drive the clamping mechanism 53 to slide back and forth along the slide rail 51. When the clamping mechanism 53 clamps a pallet, the drive mechanism 55 drives the clamping mechanism 53 to slide along the slide rail 51 to a preset position, then the clamping mechanism 53 releases its grip on the pallet, causing the pallet to fall, and then the clamping mechanism 53 returns to its original position along the slide rail 51 to clamp a new pallet.

[0066] like Figure 2 As shown, the feeding module 10 includes a support lifting mechanism 11 and a feeding drawer 13 disposed on the support lifting mechanism 11. The support lifting mechanism 11 lifts or lowers longitudinally, thereby driving the feeding drawer 13 to move upward or downward longitudinally. The support lifting mechanism 11 is disposed below the conveyor belt 31 longitudinally.

[0067] Please see Figure 3The supporting lifting mechanism 11 includes a lifting cylinder 111 and a lifting plate 113. The lifting cylinder 111 drives the lifting plate 113 to move longitudinally. A loading drawer 13 is disposed on the lifting plate 113. The supporting lifting mechanism 11 also includes a plurality of linear bearings 115 disposed around the lifting cylinder 111 to cooperate with the lifting cylinder 111 to drive the lifting plate 113 to move longitudinally more stably.

[0068] like Figure 2 and Figure 3 As shown, the loading drawer 13 includes a drawer slide rail 131 fixedly mounted on the lifting plate 113, two drawer side panels 133, and a pull-out panel 135 connecting the two drawer side panels 133. The two drawer side panels 133 are slidably mounted on the drawer slide rail 131 with a gap between them. The two drawer side panels 133 are located on both sides of the conveyor belt 31. Support arms 132 are fixedly mounted on the drawer side panels 133 to support the tray. The pull-out panel 135 is fixedly connected to one end of the two drawer side panels 133 to facilitate pushing and pulling the loading drawer 13 relative to the conveyor belt 31. A handle is provided on the surface of the pull-out panel 135 facing away from the drawer side panels 133 to facilitate pulling the loading drawer 13. Thus, pulling the pull-out panel 135 allows the loading drawer 13 to slide away from the conveyor belt 31, and pushing the pull-out panel 135 allows the loading drawer 13 to slide closer to the conveyor belt 31.

[0069] The lifting cylinder 111 of the supporting lifting mechanism 11 lifts the material, and the feeding drawer 13 is pulled out in a direction away from the conveyor belt 31. Figure 2 As shown, at this time, multiple pallets loaded with materials can be placed into the loading drawer 13, and the pallets are lifted by the two support arms 132; then the loading drawer 13 is pushed in along the direction close to the conveyor belt 31, the lifting cylinder 111 of the support lifting mechanism 11 descends, and the pallets on the support arms 132 fall onto the conveyor belt 31.

[0070] like Figure 1 As shown, a pallet guide plate 21 is also fixedly installed on the feeding drawer 13. The pallet guide plate 21 is fixed on the drawer side plate 133 and extends towards the conveyor belt 31, thus extending beyond the drawer side plate 133. The two pallet guide plates 21 on the two drawer side plates 133 are located on both sides of the conveyor belt 31 to guide and restrict the movement of the pallet and prevent the pallet from deviating.

[0071] The conveyor belt 31 is equipped with a drive element (not shown), such as a motor, which drives the conveyor belt 31 to rotate cyclically, thereby causing the pallets on the conveyor belt 31 to move linearly.

[0072] like Figure 2As shown, the lifting mechanism 33 includes a vertical plate 331 and two insert arms 333 slidably connected to the vertical plate 331. The vertical plate 331 is located vertically at the end of the conveyor belt 31. A guide rail 330 extending longitudinally is provided on the vertical plate 331. The two insert arms 333 are slidably mounted on the guide rail 330 and located on opposite sides of the conveyor belt 31. The two insert arms 333 are used to cooperate in lifting multiple pallets reaching the end of the conveyor belt 31 and moving the pallets upward along the guide rail 330 to the material picking area. The lifting mechanism 33 also includes a drive element (not shown) for driving the two insert arms 333 to slide along the guide rail 330.

[0073] A position sensor (not shown) is also provided at the end of the lifting mechanism 33 on the conveyor belt 31. The position sensor is used to detect whether a pallet has reached a preset position. If it is detected, the drive element of the lifting mechanism 33 drives the two insert arms 333 to move along the guide rail 330, thereby supporting multiple pallets on the conveyor belt 31 and moving them together.

[0074] Please refer to the following: Figure 1 and Figure 4 The clamping and moving module 50 includes two parallel and spaced mounting plates 511, located above the conveyor belt 31 along its longitudinal direction. A slide rail 51 is mounted on the two mounting plates 511. A slider 52 is slidably mounted on each slide rail 51. In this embodiment, two parallel and spaced slide rails 51 are provided, and two sliders 52 are mounted on each slide rail 51.

[0075] Please refer to the following: Figure 1 and Figure 4 The clamping mechanism 53 includes a fixed plate 531 fixed to the slider 52 and a tray clamping block 533 movably disposed on the fixed plate 531. The fixed plate 531 is fixed to the side of the slider 52 opposite to the slide rail 51. The tray clamping block 533 is movably disposed on the surface of the fixed plate 531 opposite to the slider 52, and is used to clamp the periphery of the tray. In this embodiment, the tray clamping block 533 includes two opposing and spaced-apart flanges (not shown), making the tray clamping block 533 U-shaped, thereby clamping and supporting the periphery of the tray (the side edge parallel to the extension direction of the slide rail 51).

[0076] like Figure 4 As shown, the clamping mechanism 53 also includes a driving element 535 for driving the tray clamping block 533 to move on the fixed plate 531. In this embodiment, the driving element 535 is a cylinder, but it is not limited thereto. Driven by the driving element 535, the tray clamping block 533 moves along the extending direction of the vertical slide rail 51, so that the tray clamping blocks 533 on the two slide rails 51 move closer to each other to clamp the tray, and the tray clamping blocks 533 oppositely arranged on the two slide rails 51 move further apart to release the tray.

[0077] like Figure 4 As shown, the clamping mechanism 53 also includes a support block 537 movably disposed on the fixed plate 531. The support block 537 is used to clamp and support the tray from the direction of the parallel slide rail 51. The support block 537 is also correspondingly provided with a driving element 539, such as a cylinder, to drive the support block 537 to move relative to the fixed plate 531 along the extension direction of the parallel slide rail 51. In this embodiment, the support block 537 includes a stop (not shown), making the support block 537 L-shaped, thereby supporting one side edge of the tray (the side edge perpendicular to the extension direction of the slide rail 51). Thus, under the cooperative action of the tray clamping block 533 and the support block 537, the tray is firmly clamped in both the extension direction of the parallel slide rail 51 and the extension direction perpendicular to the extension direction of the slide rail 51.

[0078] In this embodiment of the application, a fixing plate 531 is provided on each slide rail 51, and each fixing plate 531 is provided with two sets of tray blocks 533 and support blocks 537.

[0079] like Figure 4 As shown, the clamping and moving module 50 is also equipped with a corresponding position sensor 24, which can be mounted on the fixed plate 531. The position sensor 24 is used to determine whether a pallet has reached the preset position (material picking area), thereby activating the drive element 535 and drive element 539 to drive the pallet clamping block 533 and the support block 537 to move, thereby clamping the pallet.

[0080] When the clamping mechanism 53 clamps the pallet, the material on the pallet can be removed, for example, by gripping with a robotic arm or sucking up with a suction cup. After the material on the pallet is removed, the drive mechanism 55 drives the clamping mechanism 53 to slide along the slide rail 51, thereby taking away the empty pallet.

[0081] In the embodiments of this application, such as Figure 4 As shown, the drive mechanism 55 includes a drive element 551, a tank cable 552 disposed on one side of each mounting plate 511, a timing belt 553, and a drive pulley 555. The timing belt 553 is wound around the drive pulley 555, and is fixedly connected to the slider 52, with one end of the timing belt 553 connected to the tank cable 552. The drive element 551 drives the drive pulley 555 to rotate, which in turn drives the timing belt 553 to rotate, thereby causing the slider 52 to slide along the slide rail 51. The drive element 551 can be a servo motor, which is connected to and drives the drive pulley 555 to rotate via a rotating shaft. A tank cable bracket 554 is also disposed on one side of the mounting plate 511, and the tank cable 552 is disposed on the tank cable bracket 554.

[0082] Each slide rail 51 is also provided with limit blocks 26 at both ends to limit the sliding range of the slider 52. When the slider 52 slides to the limit block 26, it will be unable to slide forward and will return to its original position (material picking area).

[0083] like Figure 4 As shown, a pallet base 56 is also provided between the two mounting plates 511 to support the pallet. The pallet base 56 is located below the slide rail 51 along its longitudinal direction and is used to support the pallet that falls. When the clamping mechanism 53 moves to the position of the pallet base 56, the clamping mechanism 53 releases its grip on the pallet, and the pallet will fall onto the pallet base 56.

[0084] like Figure 4 As shown, the material conveying device 100 also includes a lifting drive element 58, such as a cylinder, located below the pallet base 56. The pallet base 56 allows the lifting drive element 58 to pass through, and the lifting drive element 58 passes through the pallet base 56 and abuts against the pallet for longitudinal movement.

[0085] like Figure 1 and Figure 4 As shown, the material conveying device 100 also includes a mounting bracket 61. The mounting bracket 61 is mounted above the mounting plate 511 and directly opposite the pallet base 56. The mounting bracket 61 has a through hole 610, which is large enough for the pallet to pass through, so that the lifting drive element 58 lifts the pallet through the through hole 610. A one-way check mechanism 70 is provided on the mounting bracket 61. The one-way check mechanism 70 is located on the surface of the mounting bracket 61 away from the pallet base 56 and next to the through hole 610, and protrudes towards the through hole 610. When the pallet passes through the through hole 610 longitudinally, it will come into contact with the one-way check mechanism 70. The function of the one-way check mechanism 70 is to allow the pallet to pass through when moving longitudinally upward, but to prevent the pallet from passing through when moving longitudinally downward and to be supported by the one-way check mechanism 70. In this embodiment, four one-way check mechanisms 70 are provided on the mounting bracket 61 at intervals, respectively distributed on opposite sides of the through hole 610.

[0086] like Figure 5 As shown, the one-way check mechanism 70 includes a movable block 71 and a fixed block 73. The movable block 71 is rotatably mounted on the mounting plate 511, and the fixed block 73 is fixedly mounted on the mounting plate 511 to limit the rotation range of the movable block 71. When the pallet passes the one-way check mechanism 70 longitudinally upward, it will drive the movable block 71 to rotate; when the pallet passes the one-way check mechanism 70 longitudinally downward, the movable block 71 is held between the fixed block 73 and the mounting plate 511, thereby supporting the pallet.

[0087] like Figure 5As shown, the movable block 71 includes a top surface 711 and a bottom surface 713 arranged longitudinally opposite each other, and a side surface 715 inclinedly connected between the bottom surface 713 and the top surface 711. The bottom surface 713 is placed on the mounting plate 511, the top surface 711 faces the fixed block 73, and the side surface 715 faces the through hole 610. The side surface 715 is a surface that mates with the pallet when it passes through, and its inclined arrangement facilitates the passage of the pallet longitudinally upward. A fixed shaft 72 parallel to the extension direction of the slide rail 51 is fixedly installed on the mounting plate 511, and the movable block 71 is rotatably sleeved on the fixed shaft 72. The fixed block 73 is provided with a clamping surface 731 facing the movable block 71 and a mating surface 733 connecting the clamping surface 731. The mating surface 733 is inclinedly connected to the clamping surface 731.

[0088] When the lifting drive element 58 lifts the tray upwards, and the tray passes the one-way check mechanism 70, the movable block 71 is driven to rotate around the fixed shaft 72 until the top surface 711 of the movable block 71 abuts against the mating surface 733 and can no longer rotate. Thus, the tray, lifted by the lifting drive element 58, passes through the one-way check mechanism 70. Then, the movable block 71 rotates back to its initial position and is held between the mounting plate 511 and the fixed block 73. The lifting drive element 58 then moves back down, and the tray falls onto the movable block 71. The bottom surface 713 of the movable block 71 is supported by the mounting plate 511, and the top surface 711 is held by the fixed block 73, preventing further rotation. The tray remains on the movable block 71, specifically on its top surface 711. When the lifting drive element 58 lifts the next tray upwards, passing through the one-way check mechanism 70, the tray will again remain on the movable block 71. Then, multiple stacked trays will be placed on the movable block 71.

[0089] When the material conveying device 100 is working, the support lifting mechanism 11 lifts up, pulls the feeding drawer 13 of the feeding module 10 apart from the conveyor belt 31, places multiple pallets filled with materials on the support arm 132, and then pushes the feeding drawer 13 back. As the support lifting mechanism 11 descends, the pallets on the support arm 132 are transferred to the conveyor belt 31.

[0090] The conveyor belt 31 moves the pallet to the position of the lifting mechanism 33. The lifting mechanism 33's insert arm 333 lifts the pallet and moves it longitudinally to the material picking area.

[0091] The clamping mechanism 53 clamps the topmost pallet lifted by the lifting mechanism 33. The material on the pallet is removed. The driving mechanism 55 drives the clamping mechanism 53 to slide along the slide rail 51, thereby moving the empty pallet to the preset position (the position of the pallet base 56). The clamping mechanism 53 releases its grip on the pallet, causing the pallet to fall onto the pallet base 56. The clamping mechanism 53 then slides back along the slide rail 51 to the material picking area and clamps the next pallet again.

[0092] The lifting drive element 58 passes through the pallet base 56 and abuts against the pallet, moving longitudinally upwards. It then passes through the through hole 610 and through the one-way check mechanism 70. Afterwards, the movable block 71 rotates and falls back onto the mounting plate 511. Next, the lifting drive element 58 drives the pallet downwards longitudinally, preventing it from passing through the one-way check mechanism 70, where it is held by the movable block 71. The lifting drive element 58 continues to move downwards back below the pallet base 56 to await new pallets falling onto it. This cycle repeats until the one-way check mechanism 70 holds a certain number of pallets, allowing multiple pallets to be transferred together.

[0093] The material conveying device 100 of this application, through the cooperation of the feeding module 10, the conveying module 30 and the clamping and moving module 50, loads multiple pallets into the feeding module 10 and transfers the multiple pallets onto the rotating conveyor belt 31. Then, the lifting mechanism 33 lifts the multiple pallets, and the clamping mechanism 53 clamps the top pallet lifted by the lifting mechanism 33. After the material on the pallet is removed, the clamping mechanism 53 continues to clamp the empty pallet and moves it to remove the empty pallet. In this way, the pallets carrying materials can be automatically loaded and the empty pallets can be mechanically transferred, which can meet the requirements of large-volume and high-efficiency loading and effectively improve production efficiency.

[0094] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
