Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a feeding device. Background Technology

[0002] In automated pipe processing, such as laser cutting, a feeding device is typically required to automatically load individual pipes. Existing feeding devices have complex structures and operations, and those skilled in the art desire a feeding device that simplifies both structure and operation. Utility Model Content

[0003] The main purpose of this utility model is to propose a feeding device, which aims to solve the technical problem that the structure and operation of the feeding device in the prior art are relatively complex.

[0004] To achieve the above objectives, this utility model proposes a feeding device, comprising:

[0005] The frame has a storage trough for storing multiple workpieces on its rear side, and a discharge ramp is also provided on the frame. The discharge ramp is located on the upper front side of the storage trough and is inclined to the lower front side.

[0006] An upper lifting assembly is provided on the front side of the storage tank. The upper lifting assembly includes an upper lifting drive mechanism and an upper lifting member. The upper lifting drive mechanism is connected to the upper lifting member in a transmission manner. The upper side of the upper lifting member is provided with an upper top surface. The upper top surface is inclined to the front and lower side. The upper top surface is at least partially provided in the storage tank in the front-back direction.

[0007] A push-back assembly is located on the lower side of the material dropping slope. The push-back assembly includes a push-back drive mechanism and a push-back component. The push-back drive mechanism is connected to the push-back component in a transmission manner. The push-back drive mechanism can drive the push-back component to extend backward to the upper side of the upper top surface or retract forward to the front side of the storage trough.

[0008] A material blocking assembly includes a material blocking drive mechanism and a material blocking component. The material blocking drive mechanism is pulsatorically connected to the material blocking component. The material blocking drive mechanism can drive the material blocking component to move closer to or away from the rear end of the material dropping slope. The material blocking component protrudes from the upper side of the material dropping slope, at least when it is close to the rear end of the material dropping slope.

[0009] The upper push drive mechanism can drive the upper push member to move between a first position, a second position, and a third position. In the first position, the upper push surface is located below the material storage trough. The second position is matched with the position of the push member. The third position is matched with the position of the material dropping slope, such that:

[0010] When the upper pusher rises from the first position to the second position, the pusher can extend backward to the upper side of the upper top surface, and there is a height space between the lower side of the pusher and the upper top surface that can only accommodate a single workpiece.

[0011] When the upper top member is in the third position, the upper top surface is directly opposite the dropping slope, the material stop member is located near the rear end of the dropping slope, and there is a width space between the rear side of the material stop member and the rear end of the dropping slope that can only accommodate a single workpiece.

[0012] The storage trough at the rear of the frame stores multiple workpieces awaiting loading. Before loading, the upper pusher moves to the lower side of the storage trough (first position), with the upper pusher positioned below the workpiece, while the pusher is retracted to the front of the storage trough. During loading, the upper pusher drive mechanism moves the upper pusher upward to the second position. During this upward movement, the upper pusher lifts some workpieces from the storage trough, leaving some on the upper pusher surface. Then, the pusher drive mechanism extends the pusher backward to the upper side of the upper pusher surface. Because there is only enough space between the lower side of the pusher and the upper pusher surface to accommodate a single workpiece, the pusher can push the workpieces stacked on top of the upper pusher surface into the storage trough, leaving only one layer of workpieces on the upper pusher surface. Finally, the pusher drive mechanism retracts the pusher forward back to the storage trough. The front side of the groove does not affect the upward movement of the upper ejector and the workpiece. Then, the upper ejector drive mechanism continues to drive the upper ejector upward to the third position. At this time, the upper ejector surface is directly opposite the rear end of the dropping slope. The workpiece on the upper ejector surface will slide onto the dropping slope under the action of gravity. The stopper blocks the workpiece on the upper side of the dropping slope. Since the stopper is set close to the upper ejector at this time, there is a space between the rear side of the stopper and the rear end of the dropping slope that can only accommodate a single workpiece. Therefore, when the upper ejector drive mechanism drives the upper ejector downward, only one workpiece can remain on the dropping slope. Finally, the stopper drive mechanism drives the stopper away from the rear end of the dropping slope. The single workpiece remaining on the dropping slope can slide forward along the dropping slope to the loading position, thereby realizing the loading of a single pipe. The structure and operation are relatively simple.

[0013] Preferably, the upper support is an upper plate, which is slidably connected to the frame. The upper plate can slide up and down along the frame, can move downwards to the lower side of the storage trough, and can lift the workpiece upwards from the storage trough.

[0014] Preferably, the length of the upper top plate in the vertical direction is greater than the distance from the bottom of the storage trough to the material dropping slope. This way, when the upper top plate is lifted upwards, its lower side can block the workpiece, preventing the workpiece in the storage trough from sliding to the bottom of the upper top plate and obstructing its downward movement.

[0015] Preferably, the upper lifting component includes an upper lifting block and an upper lifting strip. The upper lifting block is slidably connected to the frame, the upper lifting drive mechanism is drively connected to the upper lifting block, and the upper lifting strip is rotatably connected to the upper lifting block. The upper lifting surface is disposed on the upper lifting strip, and the lifting state is defined as the state in which the upper lifting strip rotates to the position where the upper lifting surface is tilted forward and downward. The upper lifting block is provided with a limiting block, which is used to limit the upper lifting strip from rotating backward and downward in the lifting state. The upper lifting block is also provided with a reset structure, which is matched with the upper lifting strip and enables the upper lifting strip to rotate back to the lifting state.

[0016] The upper lifting drive mechanism drives the upper lifting block and upper lifting bar to move up and down. When the upper lifting bar is below the storage tank, it is in a horizontally placed lifting state. Then, the upper lifting block and upper lifting bar move upward, lifting the workpiece from the storage tank. The limiting block supports and prevents the upper lifting bar from rotating downward. When the upper lifting bar moves downward after a workpiece is loaded, it will rotate upward after touching the workpiece in the storage tank. At the same time, the upper lifting bar will cooperate with the reset structure to generate a spring-back tendency, preventing the workpiece from obstructing the downward movement of the upper lifting bar. When the upper lifting bar descends to below the workpiece in the storage tank, the reset structure can automatically rotate the upper lifting bar back to the lifting state, allowing for the next loading cycle. This reduces the volume of the upper lifting component.

[0017] Preferably, the limiting block is located on the rear side of the rotation axis of the upper top bar, and the reset structure is located on the front side of the rotation axis of the upper top bar. The reset structure includes a spring and a reset rod. The reset rod is slidably connected to the upper top block, and the spring is sleeved on the reset rod. The upper top bar is provided with a reset pressure surface. The reset pressure surface can press against the upper end of the reset rod and compress the spring when the upper top bar rotates forward and upward. The spring can provide an upward rebound force to the reset rod.

[0018] Preferably, the bottom of the storage tank is provided with a storage ramp, which is inclined downwards and forwards. When the workpiece is stored in the storage tank, due to the arrangement of the storage ramp, the workpiece will tend to slide downwards and forwards. When the top piece is in the first position, the workpiece can automatically slide onto the top surface.

[0019] Preferably, a push rod is rotatably connected to the frame, the push rod is located on the lower side of the storage trough, the front side of the push rod is rotatably connected to the frame, and the frame is also provided with a push driving mechanism, the push driving mechanism is rotatably connected to the rear side of the push rod, the push driving mechanism can drive the rear side of the push rod to move up and down, and when the rear side of the push rod moves upward, the push rod is tilted forward and downward.

[0020] The workpiece is stored in the storage tank. The push rod is normally in a basically horizontal state. When the upper part is in the first position, the push drive mechanism drives the rear side of the push rod to move upward, so that the push rod is tilted forward and downward, allowing the workpiece to slide onto the upper surface.

[0021] Preferably, the upper side of the material stop protrudes from the upper side of the material dropping slope, and the material stop driving mechanism can drive the material stop to move between the front end and the rear end of the material dropping slope.

[0022] When the stopper blocks a single workpiece near the rear end of the dropping ramp, the stopper drive mechanism can drive the stopper to move forward. At the same time, the workpiece also slides forward and can be blocked by the stopper to control the downward speed. This can reduce the speed and impact of the workpiece sliding to the front end of the dropping ramp.

[0023] Preferably, the material-stopping drive mechanism and the material-stopping component are located at the rear of the material-dropping inclined surface. The material-stopping drive mechanism includes a material-stopping up-and-down drive mechanism, which can drive the material-stopping component to protrude upwards from the upper side of the material-dropping inclined surface or to retract downwards below the lower side of the material-dropping inclined surface. When the material-stopping component blocks a single workpiece near the rear end of the material-dropping inclined surface, the material-stopping drive mechanism can drive the material-stopping component to retract downwards below the lower side of the material-dropping inclined surface, and then the workpiece on the material-dropping inclined surface can slide forward along the material-dropping inclined surface for loading.

[0045] like Figures 1 to 15 As shown, a feeding device includes a frame 1, an upper lifting assembly 2, a push-back assembly 3, and a blocking assembly 4.

[0046] The rear side of the frame 1 is provided with a storage trough 11 for storing multiple workpieces 5. In actual use, multiple feeding devices arranged left and right are set up to support the workpieces 5 placed on the left and right. The frame 1 is also provided with a discharge ramp 12, which is located on the upper front side of the storage trough 11 and is inclined forward and downward. The workpieces 5 are fed to the front side of the discharge ramp 12 for subsequent conveying and processing. The workpieces 5 can be tubes with various cross-sectional shapes such as round tubes, square tubes, and rectangular tubes.

[0047] The upper lifting assembly 2 is located on the front side of the storage tank 11. The upper lifting assembly 2 includes an upper lifting drive mechanism 21 and an upper lifting member 22. The upper lifting drive mechanism 21 is connected to the upper lifting member 22 in a transmission manner. The upper side of the upper lifting member 22 is provided with an upper lifting surface 221. The upper lifting surface 221 is inclined to the front and lower side. The upper lifting surface 221 is at least partially located in the storage tank 11 in the front-back direction.

[0048] The push-back assembly 3 is located on the lower side of the unloading slope 12. The push-back assembly 3 includes a push-back drive mechanism 31 and a push-back component 32. The push-back drive mechanism 31 is connected to the push-back component 32 in a transmission manner. The push-back drive mechanism 31 can drive the push-back component 32 to extend backward to the upper side of the upper top surface 221 or retract forward to the front side of the storage groove 11. The push-back drive mechanism 31 can be a cylinder, a lead screw motion module, or a gear and rack motion module, etc.

[0049] The material blocking assembly 4 includes a material blocking drive mechanism 41 and a material blocking element 42. The material blocking drive mechanism 41 is connected to the material blocking element 42 in a transmission manner. The material blocking drive mechanism 41 can drive the material blocking element 42 to approach or move away from the rear end of the material dropping slope 12. The material blocking element 42 protrudes from the upper side of the material dropping slope 12 at least when it is close to the rear end of the material dropping slope 12.

[0050] The upper push drive mechanism 21 can drive the upper push member 22 to move between a first position, a second position, and a third position. In the first position, the upper push surface 221 is located on the lower side of the material storage trough 11. The second position is matched with the position of the push member 32, and the third position is matched with the position of the material dropping slope 12, so that:

[0051] When the upper pusher 22 rises from the first position to the second position, the pusher 32 can extend backward to the upper side of the upper top surface 221. The lower side of the pusher 32 and the upper top surface 221 leave a height space H that can only accommodate a single workpiece 5. The height space H cannot accommodate two workpieces 5 stacked on top of each other. Preferably, by changing the position of the upper pusher 22, the height of the height space H can be changed, which can adapt to the feeding of pipes of different specifications.

[0052] When the upper top member 22 is in the third position, the upper top surface 221 is directly opposite the material dropping slope 12. The material stop member 42 is set close to the rear end of the material dropping slope 12. There is a width space W between the rear side of the material stop member 42 and the rear end of the material dropping slope 12, which can only accommodate a single workpiece 5. The width space W cannot accommodate two workpieces 5 arranged one after the other. Preferably, by changing the position of the material stop member 42, the width of the width space W can be changed, which can adapt to the feeding of pipes of different specifications.

[0053] The general working process of this utility model is as follows:

[0054] The material storage trough 11 at the rear of the frame 1 stores multiple workpieces 5 to be loaded. Before loading, refer to... Figure 3 and Figure 10 The upper pusher 22 first moves to the lower side of the storage tank 11, i.e., the first position, and the upper pusher 22 is located on the lower side of the workpiece 5, while the pusher 32 is in the position of retracting to the front side of the storage tank 11.

[0055] During feeding, the upper push drive mechanism 21 drives the upper push member 22 to move upward to the second position, as shown in the reference. Figure 4 and Figure 12 During the upward movement of the upper top part 22, it will lift some of the workpieces 5 in the storage tank 11 upward, and leave some of the workpieces 5 on the upper top surface 221.

[0056] Then, the push-back drive mechanism 31 drives the push-back member 32 to extend backward to the upper side of the upper top surface 221, referring to... Figure 5 and Figure 12 Since there is a height space between the lower side of the pusher 32 and the upper top surface 221 that can only accommodate a single workpiece 5, the pusher 32 can push the workpiece 5 stacked on the upper top surface 221 into the storage tank 11, leaving only one layer of workpiece 5 on the upper top surface 221.

[0057] Next, the push-back drive mechanism 31 drives the push-back component 32 to retract forward to the front side of the storage tank 11, without affecting the upward movement of the upper push component 22 and the workpiece 5.

[0058] Then, the upper drive mechanism 21 continues to drive the upper pusher 22 upward to the third position, referring to... Figure 6 and Figure 13 At this time, the upper top surface 221 is directly opposite the rear end of the dropping slope 12. The workpiece 5 on the upper top surface 221 will slide onto the dropping slope 12 under the action of gravity. The stop member 42 blocks the workpiece 5 on the upper side of the dropping slope 12. Since the stop member 42 is set close to the upper top member 22 at this time, there is a space between the rear side of the stop member 42 and the rear end of the dropping slope 12 that can only accommodate a single workpiece 5. Therefore, when the upper top drive mechanism 21 drives the upper top member 22 to move downward, only one workpiece 5 can remain on the dropping slope 12. (Refer to...) Figure 7If there are other workpieces 5 on the top surface 221, they will move downwards along with the top part 22;

[0059] Finally, the material stop drive mechanism 41 drives the material stop 42 away from the rear end of the material drop slope 12, referring to... Figure 8 and Figure 14 The single workpiece 5 remaining on the unloading ramp 12 can slide forward along the unloading ramp 12 to the loading position, thereby realizing the loading of a single pipe. The structure and operation are relatively simple. Then the upper part 22 descends back to the first position, and the above operation process is repeated.

[0060] In some specific embodiments, reference is made to Figures 1 to 8 The upper lifting component 22 is an upper lifting plate, which is slidably connected to the frame 1. The upper lifting plate can slide up and down along the frame 1, can move downward to the lower side of the storage tank 11, and can lift the workpiece 5 from the storage tank 11 upward.

[0061] Furthermore, the length of the upper top plate in the vertical direction is greater than the distance from the bottom of the storage trough 11 to the material dropping slope 12. In this way, when the upper top plate is pushed upward, the lower side of the upper top plate can block the workpiece 5, so as to prevent the workpiece 5 in the storage trough 11 from sliding to the bottom of the upper top plate and blocking the downward movement of the upper top plate.

[0062] In some specific embodiments, reference is made to Figures 9 to 15 The upper lifting component 22 includes an upper lifting block 23 and an upper lifting bar 24. The upper lifting block 23 is slidably connected to the frame 1. The upper lifting drive mechanism 21 is drivenly connected to the upper lifting block 23. The upper lifting bar 24 is rotatably connected to the upper lifting block 23. The upper lifting surface 221 is provided on the upper lifting bar 24. The state when the upper lifting bar 24 is rotated to the upper lifting surface 221 tilted to the forward and downward side is the lifting state. The upper lifting block 23 is provided with a limiting block 231, which is used to limit the upper lifting bar 24 from rotating to the rear and downward side when in the lifting state. The upper lifting block 23 is also provided with a reset structure 25, which is matched with the upper lifting bar 24. The reset structure 25 can make the upper lifting bar 24 rotate and reset to the lifting state.

[0063] The upper lifting drive mechanism 21 drives the upper lifting block 23 and the upper lifting bar 24 to move up and down. When the upper lifting bar 24 is below the storage tank 11, it is in a horizontally placed lifting state. Then, the upper lifting block 23 and the upper lifting bar 24 move upward, and the upper lifting bar 24 lifts the workpiece 5 from the storage tank 11. The limiting block 231 can support and restrict the upper lifting bar 24 from rotating downward. When the upper lifting bar 24 moves downward after the workpiece 5 is loaded, it will rotate upward after touching the workpiece 5 in the storage tank 11. (Refer to...) Figure 15Simultaneously, the upper ejector bar 24, in conjunction with the reset structure 25, exhibits a springback tendency, preventing the workpiece 5 from obstructing the downward movement of the upper ejector bar 24. When the upper ejector bar 24 descends to the lower side of the workpiece 5 within the storage trough 11, it separates from the workpiece 5, and the reset structure 25 automatically rotates and resets the upper ejector bar 24 to the lifting state, allowing for the next feeding cycle. This reduces the volume of the upper ejector component 22.

[0064] Furthermore, the limiting block 231 is located on the rear side of the rotation axis of the upper top bar 24, and the reset structure 25 is located on the front side of the rotation axis of the upper top bar 24. The reset structure 25 includes a spring 251 and a reset rod 252. The reset rod 252 is slidably connected to the upper top block 23. The spring 251 is sleeved on the reset rod 252. The lower end of the spring 251 abuts against the upper top block 23, and the upper end of the spring 251 abuts against the reset rod 252. The upper top bar 24 is provided with a reset pressure surface 241. The reset pressure surface 241 can press against the upper end of the reset rod 252 and compress the spring 251 when the upper top bar 24 rotates forward and upward. The spring 251 can provide an upward rebound force to the reset rod 252.

[0065] When the upper top bar 24 is touched by the workpiece 5 and rotates upward, the reset pressure surface 241 will press down against the upper end of the reset top rod 252 and compress the spring 251; when the upper top bar 24 leaves the workpiece 5, the spring 251 resets and pushes the reset top rod 252 and the reset pressure surface 241 upward, so that the upper top bar 24 rotates to the lifting state.

[0066] In some specific embodiments, reference is made to Figure 9 The bottom of the storage tank 11 is provided with a storage slope 111, which is inclined forward and downward. When the workpiece 5 is stored in the storage tank 11, due to the setting of the storage slope 111, the workpiece 5 will have a tendency to slide forward and downward. When the upper top part 22 is in the first position, the workpiece 5 can automatically slide onto the upper top surface 221.

[0067] In some specific embodiments, reference is made to Figure 1 and Figure 2 A push rod 13 is rotatably connected to the frame 1. The push rod 13 is located on the lower side of the storage trough 11. The front side of the push rod 13 is rotatably connected to the frame 1. The frame 1 is also provided with a push drive mechanism 14. The push drive mechanism 14 is rotatably connected to the rear side of the push rod 13. The push drive mechanism 14 can drive the rear side of the push rod 13 to move up and down. When the rear side of the push rod 13 moves upward, the push rod 13 is tilted forward and downward.

[0068] Workpiece 5 is stored in storage tank 11. Push rod 13 is normally in a basically horizontal state. When the upper top part 22 is in the first position, push drive mechanism 14 drives the rear side of push rod 13 to move upward, so that push rod 13 is tilted forward and downward, so that workpiece 5 slides onto upper top surface 221. Push drive mechanism 14 can be a cylinder or lead screw or other drive mechanism.

[0069] In some specific embodiments, the upper side of the baffle 42 protrudes from the upper side of the dropping slope 12, and the baffle drive mechanism 41 can drive the baffle 42 to move between the front end and the rear end of the dropping slope 12.

[0070] The upper side of the baffle 42 protrudes above the upper side of the dropping slope 12. When the baffle 42 blocks a single workpiece 5 near the rear end of the dropping slope 12, the baffle drive mechanism 41 can drive the baffle 42 to move forward. At the same time, the workpiece 5 also slides forward and can be blocked by the baffle 42 to control the downward speed. This can reduce the speed and impact of the workpiece 5 sliding to the front end of the dropping slope 12.

[0071] Furthermore, the material blocking drive mechanism 41 includes a material blocking slide rail, a material blocking drive motor, a material blocking main synchronous pulley, and a material blocking slave synchronous pulley. The material blocking slide rail is fixedly connected to the frame 1, the material blocking component 42 is slidably connected to the material blocking slide rail, the material blocking main synchronous pulley and the material blocking slave synchronous pulley are rotatably connected to the frame 1, a material blocking synchronous belt is wound around the material blocking main synchronous pulley and the material blocking slave synchronous pulley, the material blocking synchronous belt is connected to the material blocking component 42, the material blocking drive motor is relatively fixed to the frame 1, and the material blocking drive motor is drively connected to the material blocking main synchronous pulley. In some other embodiments, the material blocking drive mechanism 41 may also adopt a lead screw motion module or a gear and rack motion module, etc.

[0072] In some specific embodiments, the material blocking drive mechanism 41 and the material blocking member 42 are located at the rear of the material dropping slope 12. The material blocking drive mechanism 41 includes a material blocking up and down drive mechanism, which can drive the material blocking member 42 to protrude upwards from the upper side of the material dropping slope 12 or to retract downwards below the lower side of the material dropping slope 12.

[0073] When the baffle 42 blocks a single workpiece 5 near the rear end of the dropping slope 12, the baffle drive mechanism 41 can drive the baffle 42 to retract downward below the lower side of the dropping slope 12, which can be understood as moving away from the rear end of the dropping slope 12.
