In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] In automation solution design, there are many different material loading methods, such as silos, vibrating plates, feeders, and horizontal vibrations. When loading irregularly shaped magnetic materials, multiple pieces must be loaded one by one according to the set polarity. Separating these magnetically attracted materials presents a pressing challenge.

[0039] In order to solve the above problems, the present invention provides a magnetic separation device 100. Figures 1 to 2 This is a specific embodiment of the magnetic separation device 100 provided by the present invention.

[0040] See also Figures 1 to 2 The magnetic separation device 100 includes a machine base 1, a material taking mechanism 2, a material discharging mechanism 3 and a separation mechanism 4. The machine base 1 is provided with a separation station 1a; the material taking mechanism 2 includes a carrying portion 21 for carrying a material tube 200; the material discharging mechanism 3 includes a driving portion, which is movably arranged to drive each magnetic material 300 in the material tube 200 to move from the material tube 200 to the separation station 1a in sequence; the separation mechanism 4 includes a separation portion 41 movably arranged in the up and down directions, and the separation portion 41 is used to support the magnetic material 300 in the separation station 1a during its movable stroke, so that the magnetic material 300 in the separation station 1a is staggered and separated from other magnetic materials 300 in the material tube 200.

[0041] In the technical solution provided by the present invention, the carrying part 21 carries the material tube 200, and the driving part moves a magnetic material 300 near the tube mouth in the material tube 200 from the material tube 200 to the separation station 1a. When the magnetic material 300 is in the separation station 1a, the separation part 41 approaches and resists the magnetic material 300 in the separation station 1a. The separation part 41 further moves, so that the magnetic material 300 in the separation station 1a is staggered and separated from other magnetic materials 300 in the material tube 200. Subsequently, the driving part continues to move the magnetic material 300 near the tube mouth in the material tube 200 to the separation station 1a, and the separation part 41 again separates the magnetic material 300 in the separation station 1a from other magnetic materials 300 in the material tube 200, so as to provide a magnetic separation device 100 that can sequentially separate multiple magnetic materials 300 magnetically attracted in the material tube 200.

[0042] It should be noted that the separation part 41 can be pressed down by setting a pressure head, or can be set by negative pressure adsorption or magnetic attraction to magnetically fix the magnetic material 300 in the separation station 1a and separate it from other magnetic materials 300.

[0043] It can be understood that the method for moving the multiple magnetic materials 300 in the material tube 200 to the separation station 1a in sequence can be to provide a push rod at the end of the material tube 200 away from the separation station 1a, and the push rod can push the multiple magnetic materials 300 in the material tube 200 toward the separation station 1a. Of course, it is also possible to provide an adsorption rod on the side of the material tube 200 close to the separation station 1a, and the adsorption rod can drag the multiple magnetic materials 300 in the material tube 200 toward the separation station 1a.

[0044] Considering that the magnetic material 300 in the material tube 200 is of different sizes or shapes, when a push rod is set at the end of the material tube 200 away from the separation station 1a for pushing, the two adjacent magnetic materials 300 are prone to misalignment and jamming, making it difficult to achieve the purpose of moving the magnetic material 300 close to the separation station 1a to the separation station 1a.

[0045] Furthermore, in this embodiment, the driving portion includes a laterally movable suction rod 5 , which is laterally spaced from the supporting portion 21 . The suction rod 5 has a material-removing position and a positioning position during its travel. In the material-removing position, the suction rod 5 is positioned close to the orifice of the feed pipe 200 to absorb the magnetic material 300 adjacent to the orifice within the feed pipe 200. In the positioning position, the suction rod 5 is positioned away from the orifice of the feed pipe 200 to pull the absorbed magnetic material 300 to the separation station 1 a. In this manner, by attracting and pulling the magnetic material 300 outward, misalignment between adjacent magnetic materials 300 within the feed pipe 200 is avoided.

[0046] Compared with the method of pushing by a push rod, the pushing stroke of the push rod is related to the length of the material tube 200. Therefore, a driving device with a larger active stroke is required to drive the push rod to move. In addition, when the length of the special-shaped magnetic material 300 is inconsistent, it is not easy to control the active distance of each push by the push rod.

[0047] The suction rod 5, on the other hand, uses an outward suction and pulling method. Its travel is relatively short, requiring it to only pull the magnetic material 300 near the pipe opening outward by a length equal to or greater than one magnetic material 300 and less than two magnetic materials 300. Furthermore, the travel of the driving device that drives the suction rod 5 does not need to change with the remaining material in the pipe 200. This makes it easier to control mechanical automation design.

[0048] Specifically, the suction rod 5 can be configured as a hollow tube, with a negative pressure device installed at one end of the hollow tube away from the separation station 1a. The suction rod 5 uses the negative pressure to achieve suction. In this embodiment, the suction rod 5 is made of a magnetic conductive material or a magnetic material. This configuration utilizes the material properties of the suction rod 5 itself and the magnetic force between the suction rod 5 and the magnetic material 300 to generate a suction force that drags the magnetic material 300, thereby simplifying the structure and reducing manufacturing costs.

[0049] It should be noted that when the length of the material tube 200 is constant, since the magnetic materials 300 in the material tube 200 are of different shapes, and after different magnetic materials 300 are installed in the material tube 200, the total length of the multiple magnetic materials 300 located in the tube is difficult to be exactly the same as the length of the material tube 200. When it is necessary to adsorb the magnetic materials 300 located in the material tube 200, the suction rod 5 needs to be extended into the material tube 200 for adsorption. Therefore, the movable stroke distance of the suction rod 5 needs to be slightly adjusted.

[0050] Furthermore, in order to make the magnetic separation device 100 more versatile and adaptable to separating magnetic materials 300 of different specifications, in this embodiment, the discharging mechanism 3 also includes a loading platform 31 and a magnetic attraction part 32, and the loading platform 31 and the bearing part 21 are arranged at intervals in the horizontal direction, and the gap between the loading platform 31 and the bearing part 21 forms the separation station 1a; the magnetic attraction part 32 is arranged on the loading platform 31, and the magnetic attraction part 32 is used to be set corresponding to the pipe mouth of the material tube 200, and is used to magnetically attract each magnetic material 300 in the material tube 200; the suction rod 5 is provided on the side of the magnetic attraction part 32 away from the bearing part 21, and the suction rod 5 is used to magnetically fix the magnetic material 300 through the magnetic attraction part 32 during its active stroke.

[0051] With such an arrangement, there is no need to adjust the movable travel distance of the suction rod 5, only the length of the magnetic suction part 32 needs to be adjusted. When the magnetic material 300 near the pipe mouth in the pipe is far away from the pipe mouth, the longer magnetic suction part 32 can be selected. When the movable distance of the suction rod 5 remains unchanged, the suction rod 5 can still absorb and take the material through the magnetic suction part 32; conversely, when the magnetic material 300 near the pipe mouth in the pipe is close to the pipe mouth, the shorter magnetic suction part 32 can be selected.

[0052] Furthermore, in this embodiment, the magnetic attraction portion 32 includes a plurality of magnets arranged in a transverse direction, with each adjacent pair of magnets magnetically connected. Thus, by configuring the magnetic attraction portion 32 in a segmented manner, the number of magnets can be flexibly adjusted based on the distance between the magnetic material 300 near the pipe opening and the pipe opening, thereby achieving the purpose of adjusting the length of the magnetic attraction portion 32.

[0053] Of course, the magnet itself has a certain degree of magnetism. When the magnetic material 300 is adsorbed near the tube mouth of the material tube 200, the magnetic force of the magnetic material 300 becomes stronger. When the material is taken and adsorbed and pulled to the separation station 1a, it is more difficult to separate.

[0054] It should also be noted that the magnet can be provided as a standard accessory, or can be a magnetic material 300 from a batch of magnetic material 300 in the material tube 200 as the magnet.

[0055] Furthermore, to ensure that the magnetic portion 32 remains stable during lateral movement, in this embodiment, a retaining groove 31a is recessed in the top of the loading platform 31. The retaining groove 31a extends laterally and accommodates the magnetic portion 32. Thus, the two sidewalls of the retaining groove 31a limit the position of the magnetic portion 32, preventing the magnetic portion 32 from swinging and becoming unstable when the push rod moves the magnetic portion 32 laterally.

[0056] Specifically, in this embodiment, a recess 21a is formed on the top of the support portion 21 to accommodate the feed tube 200. The recess 21a extends laterally and corresponds to the retaining groove 31a. The inner wall of the recess 21a limits the circumference of the feed tube 200, preventing the feed tube 200 from becoming unstable and rolling when the suction rod 5 approaches it, which could result in misalignment during material removal.

[0057] Furthermore, when separating the magnetic material 300, in order to prevent the magnetic attraction portion 32 from moving along with the magnetically attracted magnetic material 300 when the magnetic attraction between the magnetic attraction portion 32 and the suction rod 5 is insufficient, in this embodiment, the separation mechanism 4 further includes a first pressing head 42, which is movable in the up-down direction and is used to press the magnetic attraction portion 32 against the loading platform 31 during the downward movement. In this way, the magnetic material 300 adjacent to the magnetic material 300 in the separation station 1a is constrained and limited by the pipe mouth of the material tube 200, and the magnetic attraction portion 32 is clamped and constrained by the loading platform 31 and the first pressing head 42, making it easier for the separation portion 41 to perform separation.

[0058] In this embodiment, the separation mechanism 4 further includes a second pressing head 43, which is movable in the vertical direction and is used to press the material tube 200 against the supporting portion 21 during its downward movement. This arrangement confines the material tube 200 between the supporting portion 21 and the second pressing head 43, preventing the material tube 200 from tilting when the separation portion 41 separates the magnetic material 300.

[0059] Furthermore, in order to ensure that the falling magnetic material 300 falls according to the set polarity, in this embodiment, the magnetic separation device 100 further includes a silo provided corresponding to the separation station 1a, the silo being located below the separation portion 41, and the silo forming a trough with an upward opening, the bottom of which is provided with a magnetic block, which is used to magnetically attract the separation portion 41 to separate the falling magnetic material 300. In this way, when the magnetic material 300 falls, opposite poles attract, and the polarity of the lower end of the magnetic material 300 is opposite to that of the upper end of the magnetic block, thereby ensuring that each falling magnetic material 300 can be arranged with the same set magnetic pole, which is convenient for subsequent loading.

[0060] The present invention also provides a loading device, which includes the above-mentioned magnetic separation device 100, and the loading device also includes a material pipe 200 separation device. Since the loading device includes the magnetic separation device 100, the specific structure of the magnetic separation device 100 refers to the above-mentioned embodiment. Since the magnetic separation device 100 of this loading device adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0061] Specifically, the material pipe 200 separation device includes a hopper assembly and a feeding mechanism provided on the machine base 1, the hopper assembly includes a material receiving part provided on the machine base 1, the material receiving part is formed with a material channel for placing multiple material pipes 200, the material channel extends in the up and down directions, and is spaced apart from the machine base 1; the feeding mechanism includes a separation seat, the separation seat is movably provided between the machine base 1 and the material channel, the separation seat has a material picking position and a loading position in its movable stroke; wherein, a material picking part is provided on the separation seat, and when the separation seat moves to the material picking position, the material picking part corresponds to the lower end of the material channel and picks up a material pipe 200 located at the lower end of the material channel, and when the separation seat moves to the loading position, the material picking part is separated and staggered from the material channel.

[0062] The magnetic materials 300 are first loaded into the material tube 200 in sequence. Since the different polarities of two adjacent magnetic materials 300 attract each other, before loading multiple magnetic materials 300 into the material tube 200, each two adjacent magnetic materials 300 are magnetically connected to each other, so that the multiple magnetic materials 300 in the material tube 200 can be arranged in the material tube 200 according to the set magnetic pole direction. Then, each material tube 200 is placed into the material channel from the upper end of the material receiving part and the upper end of the material channel. The material tubes 200 are arranged and stacked from bottom to top in the material channel. Then, the separation seat moves to the material taking position, corresponding to the lower end of the material channel. The material tube 200 at the bottom of the material channel falls downward due to gravity. At this time, After the material picking part picks up the material tube 200, it moves to the loading position to facilitate the subsequent loading and separation process of the magnetic material 300. After the subsequent loading and separation process of the magnetic material 300 is completed, the empty material tube 200 is taken away, and the separation seat returns from the loading position to the material picking position, and corresponds to the lower end of the material channel again to carry out the next material picking process. Because the length of the material tube 200 matches the width of the material channel, after the material tube 200 picked up by the material picking part is transported to the loading position, the end position of the material tube 200 is determined, which is convenient for the subsequent separation process of the magnetic material 300 from the end of the material tube 200, so as to provide a material tube 200 separation device that is convenient for the subsequent separation of multiple special-shaped magnetic materials 300.

[0063] Specifically, the material-retrieving portion can be configured as a clamping claw or a material-retrieving component such as a suction head. To facilitate processing and reduce production and processing costs, in this embodiment, the material-retrieving portion includes a separation groove recessed in the upper end of the separation seat. Thus, when the separation seat moves to the material-retrieving position, the notch of the separation groove corresponds to the lower end of the material channel, and the material tube 200 falls to the bottom of the separation groove due to gravity.

[0064] It is understandable that the shape of the separation tank can be adapted to the shape of the material pipe 200 and can be designed to follow the shape to prevent the material pipe 200 from shaking in the separation tank, which makes the state of the magnetic material 300 in the material pipe 200 unstable.

[0065] Specifically, in this embodiment, the separation seat is movably arranged along the longitudinal direction; the separation seat includes two support seats and a feeding plate, the two support seats extend along the longitudinal direction and are arranged at intervals in the transverse direction; the feeding plate is installed at one end of the two support seats in the longitudinal direction, and the feeding plate includes two support arms that are spaced apart in the transverse direction and extend upward, and the top of each support arm is recessed with a through groove extending along the transverse direction, and the two through grooves form the separation groove; wherein the tops of the two support arms are arranged flush with the tops of the two support seats.

[0066] The two arms can be arranged at the middle of the corresponding material tube 200 to support the material tube 200. The two ends of the material tube 200 can be suspended so that after the multiple magnetic materials 300 in the subsequent material tube 200 are separated in sequence, the picking mechanism can pick up the empty material tube 200 for unloading.

[0067] It is understood that the tops of the two support arms are flush with the tops of the two support seats, and the gap between them and the lower end of the material channel is less than the diameter of a material pipe 200. This ensures that only one material pipe 200 is dropped into the separation tank at a time. After the material is removed, the gap between the tops of the two support seats and the lower end of the material channel remains less than the diameter of a material pipe 200 during the movement of the two support arms from the material removal position to the material loading position. In this way, the two support seats can prevent the material pipes 200 in the material channel from falling out, thereby supporting multiple material pipes 200.

[0068] Specifically, in this embodiment, the separation seat is movably disposed longitudinally; the material receiving portion comprises two laterally spaced-apart seats, each of which has a recessed material channel on one side thereof. Each of the two seats extends vertically and upwardly through the top of its corresponding seat, forming the material channel between the two channels. Because the two seats are spaced-apart laterally, after the ends of the material tube 200 are mounted on their respective seats, the remaining amount of the material tube 200 between the two seats can be observed in real time, facilitating timely refilling of the material tube 200.

[0069] It can be understood that in another embodiment, the distance between the two seats can be closer to or farther away from each other, so that the distance between the two seats can be adjusted according to the length of the material pipe 200, so that the width of the material channel can match the length of the material pipe 200.

[0070] Furthermore, the feeding mechanism further includes a driving device mounted on the machine base 1, the driving device having a driving portion that is movable in the longitudinal direction, the driving portion being fixedly connected to the separation seat to drive the separation seat to move in the longitudinal direction. The present invention is not limited to the specific structure of the driving device, which may be a cam drive, a connecting rod drive, a screw structure, etc. Preferably, the driving device includes a cylinder or an electric cylinder. When the driving device is configured as a cylinder, the cylinder rod is configured as the driving portion, and the cylinder rod is connected to the separation seat.

[0071] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
