DETAILED DESCRIPTION

[0028] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0029] See also Figures 1 to 7The present invention provides an automatic unloading device, including a base mechanism 1, a pushing mechanism 2, an unloading mechanism 3, a rocker mechanism 4 and a monitoring mechanism 5, wherein the base mechanism 1 includes a base 11, a guide rail 12 and a feeding channel 13 arranged on the base 11, and the two ends of the feeding channel 13 are respectively provided with a first feed port 131 and a first discharge port 132; the pushing mechanism 2 includes a feeding assembly 21 slidably connected to the guide rail 12, and a first driving cylinder 22 for driving the feeding assembly 21 to send the material from the first feed port 131 to the first discharge port 132; the unloading mechanism 3 includes a unloading channel 31 and a blocking assembly 32 A second feed port 311 and a second discharge port 312 are respectively provided at the upper and lower ends of the material discharge channel 31. The second feed port 311 is vertically connected to the first discharge port 132. The material blocking assembly 32 includes a material blocking block 321 and a second driving cylinder 322 for driving the material blocking block 321 to close or open the second discharge port 312; a rocker mechanism 4 is used to prevent the material pieces falling into the material discharge channel 31 from tilting; a monitoring mechanism 5 is arranged close to the swing mechanism 4, and is used to detect the position of the swing mechanism 4 when the material discharge channel 31 is full of materials or no materials are stored, so that the material blocking block 321 opens or closes the second discharge port 312.

[0030] Specifically, when the pushing mechanism 2 pushes the material to the unloading mechanism 3, the swing mechanism 4 is propped up by the material pushed to the unloading mechanism 3, so that the material enters the unloading mechanism 3 by its own weight. After the material enters the unloading mechanism 3, the swing mechanism 4 returns to the horizontal position to press the material down so that the material does not tilt. At the same time, the pushing mechanism 2 returns to the starting position to prepare to push the next material. The action is repeated in this way, so that the material is stacked in order in the unloading channel 31 of the unloading mechanism 3. When the material in the unloading channel 31 is full, the position of the swing mechanism rises, and the monitoring mechanism 5 detects the position of the swing mechanism 4, so that the blocking block 321 opens the second discharge port 312, and the material is output from the second discharge port 312 in an orderly and horizontal position. The present invention cooperates with the unloading mechanism 3 and the swing mechanism 4, so that the slender material with a large diameter and a small diameter will not tilt during the conveying process due to the different masses at both ends of the material, thereby ensuring that the material is stacked in order in the unloading channel 31.

[0031] Furthermore, the feeding assembly 21 includes a driving slider 211 slidably connected to the guide rail 12, and a feeding push block 212 fixedly connected to the driving slider 211, and a material clamping groove 2121 for positioning the material is provided at the bottom of the feeding push block 212. The feeding channel 13 also includes two relatively parallel material slide rails 133, and the feeding push block 212 is located directly above the space between the two material slide rails 133. The base 11 is provided with a feeding channel 6 on the side away from the guide rail 12, and the discharge port of the feeding channel 6 is connected to the first feeding port 131.

[0032] Specifically, the piston rod of the first driving cylinder 22 is connected to the driving slider 211 through the connecting block. The driving slider 211 and the feeding push block 212 are designed in a U shape. Therefore, when the first driving cylinder 22 drives the driving slider 211 to reciprocate on the guide rail 12, the synchronous feeding push block 212 moves synchronously. At the same time, the feeding push block 212 is arranged directly above the space between the material slide rails 133.

[0033] In the initial state, the clamping groove 2121 of the material push block 212 is docked with the discharge port of the feed channel 6, and the material enters the clamping groove 2121 from the discharge port of the feed channel 6, and the material continues to move forward in the clamping groove 2121 until the end of the material abuts against the side wall of the material slide rail 133 on the side away from the feed channel 6, so that the two ends of the material are respectively placed on the two feeding slide rails 133, so that the material enters the first feed port 131. The material is pushed in the clamping groove 2121 by the feeding push block 212, slides along the feeding slide rail 133 through the first discharge port 132 and enters directly above the second feed port 312. At this time, the clamping groove 2121 is also directly above the second feed port 312, so that the material in the clamping groove 2121 falls into the lower feed channel 31. At the same time, in order to ensure that the material is effectively loaded into the material slot 2121, a loading sensor is provided on the base 11 close to the side of the feeding push block 212 away from the feeding channel 6.

[0034] Furthermore, the rocker mechanism 4 includes a rotating shaft 41 mounted on the base 11, a rocker 42 movably mounted on the rotating shaft 41, and a spring fixing frame 43 disposed above the rocker 42. The end of the rocker 42 away from the material discharge channel 31 is connected to the spring fixing frame 43 through a return spring 44. There are at least two rockers 42, and the spacing between the two rockers 42 matches the length of the material. The rocker 42 includes a short arm 421, a long arm 422, and an axial hole 423 disposed between the short arm 421 and the long arm 422. The rocker 42 penetrates the rotating shaft 41 through the axial hole 423. Limiting rings 45 are respectively disposed on both sides of the rocker 42 on the rotating shaft 41.

[0035] Specifically, the long arm 422 of the swing rod 42 is placed on the path of the material conveying direction, and the swing rod 42 swings with the rotating shaft 41 as the support point, and swings elastically under the action of the return spring 44. When the feeding push block 212 pushes the material close to the long arm 422 of the swing rod 42, the lower end of the long arm 422 continues to receive the upward thrust of the material, and the return spring 44 is pulled down by force. When the material is pushed to the top of the second feed port 311, the swing rod 42 stops moving, and the material falls from the clamping groove 2121 to the material discharge channel 31 by its own weight. Then the feeding push block 212 is recovered, and at this time, the long arm 422 of the swing rod 42 gradually falls back downward, and the return spring 44 resets upward, so that the end of the long arm 422 of the swing rod 42 is mortgaged on the material, so that the material is horizontally stacked in the material discharge channel 31. The number of the swing rods 42 can be selected according to the length of the material. In this embodiment, two swing rods 42 are preferably used, and the spacing between the two swing rods 42 matches the axial distance of the large diameter end of the material, so as to ensure that both ends of the large diameter of the material are stressed at the same time, so that the material falls horizontally, and the material is prevented from tilting and getting stuck. In order to prevent the swing rod 42 from deflecting during operation, limit rings 45 are respectively provided on both sides of the swing rod 42, so as to ensure the stability of the swing rod 42 during operation. The end of the short arm 421 is provided with a bottom groove for fixing the lower end of the return spring 44, and the upper end of the spring fixing frame 43 is provided with a groove for fixing the upper end of the return spring 44.

[0036] Furthermore, an escape groove 313 for evading the swing arm 42 is provided at the upper end of the material discharge channel 31 , so that the end of the long arm 422 can effectively press against the material in the material discharge channel 31 .

[0037] Furthermore, the monitoring mechanism 5 includes a first sensor 51 and a second sensor 52 near one side of the swing rod 42. Specifically, the first sensor 51 is used to detect the height to which the swing rod 42 is lifted, so as to confirm whether the materials placed in the material discharge channel 31 are fully stored. When fully stored, a signal is transmitted to the material blocking assembly 32, so that the second driving cylinder 322 of the material blocking assembly 32 drives the material blocking block 321 to open the second material discharge port 312. The second sensor 52 is used to detect whether the swing rod is in motion. When the pushing mechanism 2 is not pushing the material, the swing rod 42 is not in motion. After the second sensor 52 detects that the swing rod 42 is not in motion, it delays for a predetermined time and transmits a signal to the second driving cylinder 322, and the second driving cylinder 322 drives the material blocking block 321 to close the second material discharge port 311.

[0038] Furthermore, a discharge port 14 for defective materials is provided between the two material slide rails 133 on the base 11, and the lower end of the discharge port 14 is connected to a trapezoidal material guide trough 15. Specifically, if the material entering the material trough 2121 is broken, the material falls from the discharge port 14 between the material slide rails 133 during the pushing process by the material push block 212, flows out along the material guide trough 15 and is collected.

[0039] The workflow of the present invention is:

[0040] In the initial state, the feed port of the clamping groove 2121 of the feeding push block 212 is horizontally connected with the discharge port of the feeding channel 6, and the second driving cylinder 322 drives the blocking block 321 to close the second discharge port 312;

[0041] Turn on the power, the material enters the clamping groove 2121 through the feed channel 6, the first driving cylinder 22 is actuated, driving the driving slider 211, so that the feeding push block 212 pushes the material from the first feed inlet 131 to the first discharge outlet 132;

[0042] Then, the feeding push block 212 continues to move forward, and the two ends of the material in the clamping groove 2121 gradually push up the swing rod 42 placed in front of its travel path, until the clamping groove 2121 is placed directly above the second discharge port 312, the swing rod 42 is completely lifted, and the material falls into the discharge channel 31;

[0043] In the next step, the piston rod of the first driving cylinder 22 contracts, driving the feeding push block 212 to gradually move away from the second feeding port 311. At the same time, the swing rod 42 is elastically reset under the action of the return spring 44. This step is repeated to stack the materials in the material discharge channel 31 in an orderly manner until the material discharge channel 31 is filled with materials for the first time. At this time, the horizontal pressure of the swing rod 42 on the materials is optimized.

[0044] In the next step, the first sensor 51 detects that the height of the swing rod 42 has reached the point where the material discharge channel 31 is full of materials, and the piston rod of the second driving cylinder 322 contracts to drive the material stopper 321 to open the second material discharge port 312, and the materials are discharged one by one from the second material discharge port 312 in an orderly manner, and the output frequency thereof is consistent with the feeding frequency of the pushing mechanism 2;

[0045] In another step, when the second sensor 52 detects that the rocker arm 42 does not move, the signal is transmitted to the second driving cylinder 322 after 10 seconds, and the piston rod of the second driving cylinder 322 extends to drive the blocking block 321 to close the second discharge port 312 .

[0046] Turn off the power and the device stops working.

[0047] To sum up, the automatic unloading device provided by the present invention uses a rocker mechanism that cooperates synchronously when the pushing mechanism delivers the material to the unloading mechanism, so that slender cylindrical materials with different diameters can be stacked in an orderly and horizontal manner in the unloading channel, thereby solving the problem of tilting of the materials during the stacking process due to different qualities caused by different diameters of the materials, effectively preventing the materials from getting stuck in the unloading channel, saving production time and improving production efficiency.
