Robotic loading, on the other hand, requires significant space, and workers are prohibited from entering the robot's operating area. This makes it difficult to closely observe the loading process, hindering the timely detection and resolution of any unexpected problems encountered during loading. Summary of the Invention

[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example 1

[0034] like Figure 1 As shown, a buffer feeding device of a continuous cartoning machine includes a buffer device 1, a feeding device 2 and a material sorting and conveying device 3. The buffer device 1 and the feeding device 2 are vertically distributed in a plane, and a material sorting and conveying device 3 is provided at the intersection of the two. The buffer device 1 is used to buffer and convey materials. The materials are loaded in Figure 8 In the illustrated tray 4, the material arrangement and conveying device 3 is used to neatly arrange the material on the tray 4 and then discharge the tray 4 from a discharge port 401 on one side of the tray 4. The feeding device 2 is used to receive the material discharged from the tray 4 and convey it to the next stage. In this embodiment, the material in the tray 4 is packaging material, such as cardboard used to form packaging boxes but not folded into a finished form.

[0035] like Figure 2 As shown, the cache device 1 includes a cache rack and a cache loader 101, a suction and support mechanism 102, a recovery mechanism 103, a feeding platform 104 and a material blocking mechanism arranged on the cache rack. The cache loader 101 is tilted so that the conveying surface has a slope, which can convey the material tray carrying the material from low to high. The feeding platform 104 is located at the top of the slope of the cache loader 101 and is used to receive the material tray from the cache loader 101. The side of the feeding platform 104 extends to the outside of the cache rack for a section and is used to dock with the feeding device 2. The end of the cache rack is provided with a suction and support mechanism 102, which is used to absorb the empty material tray after the material is sent out so that the empty material tray can enter the recovery mechanism 103. The recovery mechanism 103 is used to send the empty material tray out for recycling. A material blocking mechanism is also provided at the end of the feeding platform 104 to block the forward movement of the material tray and realize the positioning of the material tray.

[0036] Continue to refer Figure 2As shown, the suction and support mechanism 102 includes a primary telescopic mechanism 1021, a secondary telescopic mechanism 1022, a slide 1023, a push plate frame 1024, a push plate 1025 and a suction cup 1026. The primary telescopic mechanism 1021 is arranged at the end of the cache rack, and the primary telescopic mechanism 1021 is connected to the slide 1023. The slide 1023 is slidably arranged on the primary slide rails on both sides of the cache rack. The secondary telescopic mechanism 1022 is arranged in the center of the upper surface of the slide 1023, and a secondary slide rail is arranged on the surface of the slide 1023 on both sides of the secondary telescopic mechanism 1022. The middle part of the push plate frame 1024 is connected to the telescopic end of the secondary telescopic mechanism 1022. The two sides of the push plate frame 1024 are slidably connected to the secondary slide rails. The push plate frame 1024 is provided with a push plate 1025 on the side facing the cache loader 101. A plurality of suction cups 1026 are provided on the side of the slide plate 1023 facing the cache loader 101 .

[0037] The first-stage telescopic mechanism 1021 is a telescopic cylinder, and the second-stage telescopic mechanism 1022 is a ball screw. In other embodiments, an electric push rod can be used instead.

[0038] The primary telescopic mechanism 1021 drives the slide 1023 toward the feeding platform 104, allowing the push plate 1025 to approach the material tray on the feeding platform 104. The lower edge of the push plate 1025 is higher than the upper edge of the material tray on the feeding platform 104, preventing interference from the material tray when the push plate 1025 is used to organize the materials in the tray. The secondary telescopic mechanism 1022 drives the push plate frame 1024 toward the material tray, allowing the push plate 1025 to organize the materials in the tray. After the materials leave the tray, the suction cup 1026 absorbs the materials from the side of the tray. The primary telescopic mechanism 1021 then drives the slide 1023 back, moving the empty tray on the feeding platform 104 to a position above the recovery mechanism 103, where it awaits collection by the recovery mechanism 103.

[0039] like Figure 3As shown, the recycling mechanism 103 includes a belt conveyor 1031, a linear lifting module 1032, a lifting slide 1033, and a support bracket 1034. Two belt conveyors 1031 are provided, arranged side by side below the buffer loader 101. The conveying surface of the belt conveyors 1031 is horizontal. Two linear lifting modules 1032 are provided, located on either side of the two belt conveyors 1031 and fixed to the buffer rack. Lifting slides 1033 slide on the tracks of the linear lifting modules 1032, and the support bracket 1034 is fixed to the lifting slides 1033. The support bracket 1034 is used to support the bottom of the material tray 4. The two linear lifting modules 1032 drive the lifting slides 1033 to move downward, moving the material tray 4 that has been discharged downward onto the belt conveyor 1031. The belt conveyor 1031 then delivers the material tray 4 for recycling.

[0040] like Figure 4 As shown, the material blocking mechanism includes a material blocking cylinder 105 and a material blocking plate 106. The material blocking cylinder 105 is fixed to the cache rack and is located below the plane of the feeding platform 104. The piston rod of the material blocking cylinder 105 is vertically upward and fixedly connected to the material blocking plate 106. After the piston rod of the material blocking cylinder 105 is retracted, the upper edge of the material blocking plate 106 is lower than the plane of the feeding platform 104, which does not affect the movement of the material tray 4 on the platform. When the piston rod of the material blocking cylinder 105 is extended, the material blocking plate 106 rises and can block the side of the material tray 4, preventing the material tray 4 from moving forward and achieving the positioning of the material tray 4.

[0041] like Figure 5 As shown, the feeding device 2 includes a feeding conveyor 201 for conveying materials, a receiving platform 202 for docking with the feeding platform 104, and a pushing mechanism 203 arranged on one side of the feeding conveyor 201. The receiving platform 202 is arranged on the inlet side of the feeding device 2 and can connect the feeding platform 104 and the feeding conveyor 201.

[0042] The structure of the pushing mechanism 203 is as follows Figure 6As shown, it includes a fixed plate 2031, a pushing track 2032, a shift rod 2033, a screw mechanism 2034, a shift rod telescopic module 2035 and a movable plate 2036. The fixed plate 2031 is fixedly arranged on the frame of the feeding device 2, and the screw mechanism 2034 is installed on the lower surface of the fixed plate 2031. The fixed plate 2031 is provided with a slide hole corresponding to the screw mechanism 2034. A pushing track 2032 is provided on each side of the slide hole. The movable plate 2036 is slidably arranged on the pushing track 2032, and the lower surface of the movable plate 2036 is connected to the nut on the screw mechanism 2034 through a connecting plate passing through the slide hole. One end of the screw mechanism 2034 is connected to a motor, which drives the screw to rotate, thereby realizing the movement of the movable plate 2036 along the screw. The moving direction of the movable plate 2036 is parallel to the conveying direction of the feeding conveyor 201. The length direction of the movable plate 2036 is perpendicular to its moving direction. A gear rod telescopic module 2035 is set on the upper surface of the movable plate 2036 along the length direction of the movable plate 2036. The gear rod 2033 is connected to the slider on the gear rod telescopic module 2035. The length direction of the gear rod 2033 is parallel to the telescopic direction of the gear rod telescopic module 2035 and is perpendicular to the conveying direction of the feeding conveyor 2031.

[0043] When the material is sent from the material tray 4 on the feeding platform 104 to the material receiving platform 202, the gear rod 2033 extends out to block the material behind to prevent the material from tipping over, and then the screw mechanism 2034 drives the movable plate 2036 and the gear rod 2033 to push the material from the material receiving platform 202 to the conveying surface of the feeding conveyor 201.

[0044] like Figure 7 As shown, the material sorting and conveying device includes a support frame 301, a linear slide rail 302, a feeding slide 303, a pressing plate cylinder 304, a sorting plate cylinder 305, a sorting plate 306 and a pressing plate 307.

[0045] The support frame 301 is fixed to the cache rack and is located above the suction support mechanism 102. Two linear slide rails 302 are arranged at intervals from top to bottom on the side of the support frame 301 facing the cache loader. The length direction of the linear slide rails 302 is perpendicular to the conveying direction of the cache loader and parallel to the conveying direction of the feeding conveyor 201. The feeding slide 303 is slidably connected to the two linear slide rails 302. A pressure plate cylinder 304 and a sorting plate cylinder 305 are provided on the side of the feeding slide 303 facing the cache loader 101. There are two sorting plate cylinders 305 and they are symmetrically arranged about the pressure plate cylinder 304. The piston rod of the sorting plate cylinder 305 is set downward and connected to the sorting plate 306. The piston rod of the pressure plate cylinder 304 is set downward and connected to the frame structure. A pressure plate 307 is fixed to the lower end of the frame structure. The frame structure is slidably connected to the guide rails on the feeding slide 303. The finishing plate 306 is a gate-shaped structure, wherein a groove in the middle portion corresponds to the pressing plate 307 , and a width of the groove in the middle portion is greater than a width of the pressing plate 307 .

[0046] After the material tray 4 is sent to the feeding platform 104 and is blocked by the material blocking plate 106, the push plate 1025 extends out and presses against the front of the material on the material tray 4, and the pressure plate 307 presses on the material. The two sorting plates 306 clamp the material from both sides of the material and sort the material. After sorting, the push plate 1025 is retracted, and the pressure plate 307 and the sorting plate 306 keep clamping the material. The feeding slide plate 303 then moves along the linear slide rail 302 toward the feeding device 2, and the material is moved out from the discharge port 401 on one side of the material tray 4 and moved to the material receiving platform 202.

[0047] The working process of the present invention is as follows:

[0048] 1. A large number of trays 4 loaded with materials are stored on the buffer loader 101, and the buffer loader 101 delivers the trays 4 to the feeding platform 104 at the top;

[0049] 2. The blocking cylinder 105 of the blocking mechanism raises the blocking plate 106 to block the frontmost material tray 4, preventing it from moving. Then the suction support mechanism 102 extends the push plate 1025 and, together with the descending pressure plate 307 and the sorting plate 306, tidies up the materials on the material tray 4.

[0050] 3. Keep the pressing plate 307 and the finishing plate 306 clamping the material, and move the feeding slide 303 along the linear slide rail 302 toward the feeding device 2, remove the material from the discharge port 401 on one side of the material tray 4, and move it to the receiving platform 202;

[0051] 4. The stop rod 2033 on the feeding device 2 extends to block the rear of the material, pushing the material from the receiving platform 202 to the conveying surface of the feeding conveyor 201, and the feeding conveyor 201 continues to convey the material forward;

[0052] 5. When the material tray 4 is recovered after the material is sent out, the material blocking cylinder 105 retracts the material blocking plate 106, and the suction cup 1026 on the suction mechanism 102 sucks the material tray 4, and the suction mechanism 102 drives the material tray 4 to move forward to the top of the recovery mechanism 103. The material tray 4 is supported on the support plate 1034 of the recovery mechanism 103, and the linear lifting module 1032 drives the support plate 1034 to fall, so that the material tray 4 falls on the belt conveyor 1031 below. The belt conveyor 1031 sends the material tray 4 to the bottom of the entrance position of the cache loader 101, which is convenient for workers to collect and recycle.

[0053] After the material sorting and conveying device 3 sends the material out of the material tray 4, it returns to its original position to wait for the next material sorting and conveying. After the push plate 1025 of the suction and support mechanism 102 completes the material sorting, it is retracted by the first-level telescopic mechanism 1021.

[0054] Example 2

[0055] The difference between this embodiment and embodiment 1 is that the suction and recovery mechanisms are no longer provided, and after the material is sent out of the tray, the empty tray is manually removed by a worker.
