DETAILED DESCRIPTION

[0037] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0038] Embodiment 1

[0039] like Figures 1 to 5 As shown, the continuous automatic material supply and collection integrated equipment includes a controller and a machine platform 1. The machine platform 1 sequentially forms a material tray transfer connection by a transfer mechanism to transfer a material receiving platform 1a, an empty material platform 1b, a full material platform 1c and a material discharge platform 1d. A material discharge robot 23 is arranged beside the material discharge platform 1d, and a material receiving robot 22 is arranged beside the material receiving platform 1a. Lifting components are arranged below the material receiving platform 1a, the empty material platform 1b, the full material platform 1c and the material discharge platform 1d. The material discharge platform 1d and A limit mechanism and a sensor 15 are set on the periphery of the material receiving platform 1a, and stacking levers 16 are set on the corners of the full material platform 1c and the empty material platform 1b. Insertion mechanisms are relatively set on the peripheries of the full material platform 1c and the empty material platform 1b, and lifting mechanisms are also relatively set on the peripheries of the full material platform 1c and the empty material platform 1b. The sensor 15 is connected to the controller through electrical signals, and the controller is electrically connected to the material discharge robot 23, the material receiving robot 22, the jacking assembly, the limit mechanism, the insertion mechanism and the lifting mechanism.

[0040] The transfer mechanism includes synchronous belts 2 arranged in parallel on both sides of the receiving platform 1a, the empty platform 1b, the full platform 1c and the unloading platform 1d. The synchronous belts 2 on both sides are connected by the synchronous wheels 3 in a tensioning transmission. The synchronous wheels 3 are driven and connected by the servo motor 4 through the belt assembly. A number of support seats 5 are fixed on the machine 1, and two left-right symmetrical slide rails are fixed on the support seats 5. The synchronous belt 2 is embedded in the slide rail to form a guided sliding connection. The servo motor 4 drives the synchronous wheel 3 to rotate forward or reverse, and the synchronous belt 2 drives the synchronous belt 2 to transport forward or reverse.

[0041] At least two transfer mechanisms are connected and arranged along a straight line, and a transition shaft 6 is set between adjacent transfer mechanisms. The transition shaft 6 is arranged parallel to the synchronous wheel 3. A plurality of transition wheels 7 are sleeved on the transition shaft 6, and the top surface height of the plurality of transition wheels 7 is flush with the top surface height of the synchronous wheel 3.

[0042] The transition shaft 6 can be rotated to make the transition wheels 7 rotate synchronously as a whole, and each transition wheel 7 can also be rotatably sleeved on the transition shaft 6. Therefore, when the material tray is transferred from one transfer mechanism to another transfer mechanism, the material tray is transferred and connected through the rolling of the transition wheels 7. Since the transition wheels 7 rotate passively, they only provide auxiliary guiding and supporting functions of rolling connection, thereby avoiding accidents of the material tray getting stuck or overturning in the connection gap.

[0043] The lifting assembly includes a lifting seat 8, on which a lifting cylinder 9 is installed, and a lifting rod extending upward from the lifting cylinder 9 is fixedly connected to a material discharge platform 1d, a full material platform 1c, an empty material platform 1b or a material collection platform 1a. A plurality of guide cylinders 10 are arranged on the lifting seat 8, and a guide column 11 is vertically slidably connected in the guide cylinder 10, and the top of the guide column 11 is fixedly connected to the material discharge platform 1d, a full material platform 1c, an empty material platform 1b or a material collection platform 1a. The lifting cylinder 9 drives the lifting and lowering of the material discharge platform 1d, a full material platform 1c, an empty material platform 1b or a material collection platform 1a, and the vertical stability during the lifting and lowering process is ensured by the sliding cooperation between the guide column 11 and the guide cylinder 10.

[0044] The limiting mechanism includes a baffle 12 located on one side of the material discharging platform 1d or the material receiving platform 1a, and at least one limiting cylinder 13 is arranged on the other side of the material discharging platform 1d or the material receiving platform 1a. A limiting block 14 is fixedly connected to the horizontal push rod of the limiting cylinder 13, and the limiting block 14 is arranged opposite to the baffle 12. The top edge of the baffle 12 is higher than the material discharging platform 1d or the material receiving platform 1a, and the limiting cylinder 13 is fixedly mounted on the support seat 5. A guide cylinder is fixedly arranged on the support seat 5, and a guide rod is fixedly arranged on the limiting block 14. The guide rod penetrates into the guide cylinder to form a horizontal sliding connection. Through the clamping action of the baffle 12 and the limiting block 14, the material tray on the material discharging platform 1d or the material receiving platform 1a is stopped and fixed.

[0045] The material receiving table 1a, the empty material table 1b, the full material table 1c and the material unloading table 1d are all square tabletops, and stacking bars 16 are erected at the four corners of the square tabletops. The stacking bars 16 are right-angle steel, and a gap is left between the bottom of the stacking bars 16 and the synchronous belt 2 for the material tray to pass through.

[0046] The stacking cavity is formed by surrounding the four stacking bars 16, and the right-angle steel is used to cover and limit the corners of the material tray, so that the material trays can be stacked and stored from bottom to top through the stacking cavity. The remaining material trays pass through the gap so that the material trays can pass through the stacking cavity under the conveyance of the synchronous belt 2.

[0047] The material inserting mechanism comprises a material inserting cylinder 17, a horizontal inserting rod of the material inserting cylinder 17 is fixedly connected to an inserting frame 18, and the inserting frame 18 is provided with at least two fork claws protruding toward the full material workbench 1c or the empty material workbench 1b.

[0048] The inserting cylinder 17 is fixed on the support base 5, a guide cylinder is fixed on the support base 5, a guide rod is fixed on the inserting frame 18, and the guide rod penetrates into the guide cylinder to form a horizontal sliding connection. The inserting frame 18 is telescopically moved between the two stacking bar 16, and the inserting frame 18 is supported and fixed by the two opposite inserting cylinders 17 synchronously extending the inserting frame 18 to support and fix the material tray in the stacking cavity.

[0049] The material lifting mechanism comprises a material lifting seat 19 fixed on the machine table 1, a material lifting cylinder 20 is mounted on the material lifting seat 19, a material lifting rod extending upward from the material lifting cylinder 20 is fixedly connected to a material lifting block 21, and the material lifting block 21 has a right-angle groove.

[0050] A guide cylinder is fixed on the lifting seat 19, and a guide rod is fixed on the lifting block 21, which penetrates into the guide cylinder to form a vertical sliding connection. The lifting cylinders 20 on both sides simultaneously raise the lifting blocks 21, so that the two symmetrical lifting blocks 21 synchronously lift the edges of the stacked material trays and raise them by one material tray height.

[0051] Compared with the existing technology, this continuous automatic feeding and receiving integrated equipment has the following advantages:

[0052] The present invention is an automatic and uninterrupted material supply and collection system applied to automated workshops. There is no need to manually change the trays during the material taking and releasing process, and in the case of mismatched material supply and collection capacity, a temporary storage and stacking cavity is added to not affect the capacity. That is, it can automatically collect empty trays and fully loaded trays, and automatically stack the empty trays and fully loaded trays, and realize uninterrupted material supply when the number of trays remains unchanged, thereby saving labor costs, improving production efficiency, and ensuring the continuity of loading and unloading, which conforms to the concept of modern mechanical automation operation, and has good market prospects for promotion and application using this technical field.
