DETAILED DESCRIPTION

[0018] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0019] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0020] like Figure 1 As shown, an embodiment of the present invention provides a metal foreign body positioning marking device for a tape conveyor, including a metal detector 1, a controller 4, a position indicating device 5, a speed detecting device 6, a frame 7, a linear module 8 (the linear module is a linear transmission device widely used in the industrial field. The working principle of the linear module is to convert the rotational motion of the servo motor into linear motion, thereby driving the slider to slide on the linear guide rail to achieve high-precision repetitive linear motion) and a grasping device 9. The controller 4 is connected to the metal detector 1, the speed detecting device 6 and the linear module 8 respectively through connecting lines.

[0021] The device can accurately locate the position of metal foreign bodies and automatically screen out the metal foreign bodies through the grabbing device 9, thereby greatly reducing the downtime of the belt conveyor, ensuring the continuous production and improving the production efficiency.

[0022] The frame 7 includes a base frame 71 and an arch frame 73 that spans the belt conveyor. Universal wheels are provided at the four corners of the bottom of the base frame 71 to improve the mobility and flexibility of the equipment as a whole. One end of the bottom of the arch frame 73 overlaps one end of the base frame 71, and the other end of the bottom of the arch frame 73 is hinged to the base frame 71. The other end of the base frame 71 is hinged with a cylinder 1 72, and one end of the cylinder 1 72 is hinged to one side of the arch frame 73. A vertical cylinder 2 74 is installed in the middle of the top crossbeam of the arch frame 73, and the linear module 8 is horizontally installed at the output end of the cylinder 2 74. Guide rods 75 that movably pass through the top crossbeam of the arch frame 73 are provided on both sides of the top of the linear module 8. By controlling the contraction of the cylinder 1 72, the arch frame 73 is forced to turn outward, thereby realizing the opening of the arch frame 73. When the arch frame 73 is opened, the device can easily pass through the belt conveyor, and then the arch frame 73 is pushed back to its original state by controlling the cylinder 1 72. The arch frame 73 spans above the belt conveyor to prepare for the subsequent work process.

[0023] The metal detector 1 spans across the tape conveyor and is arranged on one side of the arch frame 73. The signal output end of the metal detector 1 is connected to the controller 4 through a four-core connecting line. The four-core connecting line includes a start position detection line 11, a bar foreign body indication line 12, a large foreign body indication line 13 and a small foreign body indication line 14.

[0024] Under normal circumstances, the output values ​​of the starting position detection line 11 and the foreign body shape indicator (bar foreign body indicator line 12, large foreign body indicator line 13, small foreign body indicator line 14) of the metal detector 1 are all 0. When the metal object mixed in the material 3 passes through the metal detector 1, it will change the magnetic field around the metal detector 1, and the output value of the starting position detection line 11 is 1, and the type of metal foreign body is output through the foreign body shape indicator.

[0025] The position indicating device 5 is arranged at one end of the arch frame 73. When the output value of the starting position detection line 11 is 1, the position indicating device 5 is turned on to display the shape and movement trajectory of the metal foreign body in real time. The speed detecting device 6 is arranged on the bottom frame 71 and is located below the belt conveyor, and is used to measure the travel speed of the belt conveyor and the displacement of the belt of the belt conveyor.

[0026] The grabbing device 9 includes an end seat 91 fixedly mounted on the output end of the linear module 8, and two sets of parallel rotating shafts 96 are mounted on the bottom of the end seat 91. An ear seat 97 is arranged in the middle of each rotating shaft 96, and the two sets of ear seats 97 are connected by a connecting rod 910. Connecting plates 98 are arranged at both ends of the ear seat 97, and one end of each connecting plate 98 is hinged to a cylinder 99, and the output end of the cylinder 99 is hinged to the connecting plate 98 on the same side of the other ear seat 97. Support rods 95 are connected to both ends of each rotating shaft 96, and a shovel plate 94 is installed between the two sets of support rods 95 of the rotating shaft 96.

[0027] When the piston rod of the cylinder 99 is extended or shortened, it pushes or pulls the connecting plate 98 hinged thereto. Since the other end of the connecting plate 98 is connected to the connecting plate 98 on the other ear seat 97 through the connecting rod 910, this push-pull action is converted into a relative movement between the two connecting plates 98, realizing the synchronous rotation of the two rotating shafts 96, and then making the two sets of shovel plates 94 approach or move away from each other, realizing the grabbing or releasing of the material 3.

[0028] The lower end of the ear seat 97 is connected to a scraper assembly that contacts the shovel plate 94. The scraper assembly includes a cylinder 3 92 that is hinged on both sides of the end seat 91. The output end of the cylinder 3 92 is hinged to a magnetic scraper 93 that contacts the upper end surface of the shovel plate 94. The upper end of the magnetic scraper 93 is rotatably connected to the lower end of the ear seat 97. When the metal foreign matter in the material 3 is shoveled up by the shovel plate 94, the cylinders 3 92 on both sides extend their piston rods at the same time, and the magnetic scraper 93 rotates around the lower end of the ear seat 97. The two groups of magnetic scrapers 93 approach each other and closely contact the upper end surface of the shovel plate 94. As the two groups of magnetic scrapers 93 approach, the shoveled material 3 is diverted between the two groups of magnetic scrapers 93, and the metal foreign matter in the shovel plate 94 or the mixed material 3 is adsorbed and fixed by the magnetic scraper 93, thereby achieving effective screening and cleaning of the metal foreign matter in the material 3.

[0029] The speed detection device 6 includes a fixed seat 61 arranged on the base frame 71, and a steering gear 62 is arranged on the fixed seat 61. The output end of the steering gear 62 is connected to a swing arm 63, and an acceleration sensor 66 connected to the controller 4 is arranged on the swing arm 63. A distance measuring rolling wheel 64 is installed on one side of the end of the swing arm 63, and a photoelectric encoder 65 connected to the rotating shaft of the distance measuring rolling wheel 64 is installed on the other side of the end of the swing arm 63. The controller 4 is connected to the steering gear 62 and the photoelectric encoder 65 through connecting lines.

[0030] When the steering gear 62 drives the swing arm 63 to rotate, the acceleration sensor 66 detects the acceleration during the rotation process. When the distance measuring rolling wheel 64 contacts the tape, the swing arm 63 is blocked or rotates at a very small amplitude due to the restriction of the tape, and the acceleration becomes smaller. The surface tape contacts the distance measuring rolling wheel 64, and the steering gear 62 is turned off at this time. The smaller the acceleration value measured by the acceleration sensor 66, the closer the distance measuring rolling wheel 64 contacts the tape.

[0031] When the metal detector 1 finds a metal foreign body, the output value of the start position detection line 11 is 1, and the foreign body shape position indicator 5 is turned on through the bar foreign body indicator line 12, the large foreign body indicator line 13 or the small foreign body indicator line 14 according to the detection result, and the shape and movement trajectory of the metal foreign body are displayed in real time. The controller 4 controls the steering engine 62 to start, drive the swing arm 63 to rotate, and make the ranging rolling wheel 64 close to the tape of the tape machine. Under the action of friction, the ranging rolling wheel 64 rotates, and then drives the photoelectric encoder 65 to work. The photoelectric encoder 65 outputs a pulse signal proportional to the displacement of the tape. The controller 4 calculates the distance the tape runs and the time required for the metal foreign body to reach the bottom of the grasping device 9 based on the signal. After the time reaches the calculated value, the target metal foreign body will be grasped with the cooperation of the 74 linear modules 8 of the cylinder 2.

[0032] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
