Description

Technical Field

[0001] The present application relates to the technical field of needle detectors, and in particular to a split-flow and removable needle detector. Background Art

[0002] Needle detectors are also called needle detectors. They are a type of metal detector. They are mainly used to detect metal foreign bodies and are widely used in industries such as textiles, food, and logistics. The working principle of the needle detector relies on the principle of electromagnetic induction. When a metal foreign body is transmitted on the conveyor belt and passes through the detection module, it will cause changes in the local magnetic field environment, and then cause fluctuations in the instantaneous current of the local magnetic field. The needle detector will stop the conveyor belt and automatically alarm, and then manually check and inspect the object.

[0003] When the existing needle detector detects a metal foreign body, the equipment stops, affecting the subsequent object detection cycle and reducing the production efficiency of the product category. Utility Model Content

[0004] In order to improve production efficiency, the present application provides a diversion and removable needle detector.

[0005] The present application provides a split-flow removable needle detector that adopts the following technical solution:

[0006] A split-flow and removable needle detector includes a frame, a material conveyor belt arranged on the frame, and a detection module located on the conveyor belt, and further includes:

[0007] A diverter mechanism is located at one side of the conveyor belt, and the diverter mechanism includes a first driving member and a diverter plate connected to the first driving member; and

[0008] A material dropping mechanism, used to receive objects rejected from the conveyor belt side;

[0009] Among them, the detection module divides the material conveyor belt into an input section and an output section, and the diverter mechanism and the blanking mechanism are both located on one side of the output section; the first driving member is electrically connected to the detection module, and when the detection module receives a metal foreign body signal, the first driving member drives the diverter plate to slide back and forth between the conveying section and the blanking mechanism.

[0010] By adopting the above technical solution, when an object carrying a metal foreign body passes through the detection module, the detection module receives a metal foreign body signal and sends an execution signal to the diversion mechanism. The first driving member drives the diversion plate to push the object from the output section to the blanking mechanism for output collection, and then the first driving member is reset. The entire process does not require shutdown and does not affect the continuous detection of subsequent objects, thereby effectively improving production efficiency.

[0011] Preferably, the diversion mechanism further comprises:

[0012] A seat body connected to the frame; and

[0013] A swing arm, rotatably connected to the seat body;

[0014] Wherein, the swing arm connects the first driving member and the diverter plate, and when the first driving member is executed, the swing arm rotates relative to the seat body to drive the diverter plate to swing back and forth between the conveying section and the blanking mechanism.

[0015] By adopting the above technical solution, the swing of the diverter plate is achieved by rotating the swing arm relative to the seat body. The swing amplitude of the swing arm is determined by the first driving member, and the swing amplitude and the swing angle can further adjust the position of the diverter plate on the output section. The swing angle of the diverter plate can then be used to control the landing point of the object on the blanking mechanism, which is suitable for diversion and rejection operations of objects of different sizes.

[0016] Preferably, the diverter plate comprises an arc segment, one end of which extends toward one side of the blanking mechanism, and a plurality of rolling elements are further provided at the end surface of the arc segment.

[0017] By adopting the above technical solution, the setting of the arc segment effectively guides the objects, and combined with the rolling element, the objects can be quickly guided and transported from the output section to the blanking mechanism, thereby improving the conveying efficiency and conveying accuracy.

[0018] Preferably, the blanking mechanism comprises:

[0019] A transition conveyor belt is arranged adjacent to the conveying section;

[0020] A blanking conveyor belt, provided at the output end of the transition conveyor belt, the blanking conveyor belt being rotatably connected to the frame; and

[0021] The driving mechanism is connected to the blanking conveyor belt and is used for driving the blanking conveyor belt to deflect around a rotation point between the blanking conveyor belt and the frame.

[0022] By adopting the above technical solution, the objects first enter the transition conveyor belt of the blanking mechanism from the output section and then are transferred from the transition conveyor belt to the blanking conveyor belt. The transition conveyor belt can be set to a certain length so that there is a section of smooth transportation after receiving the objects. The blanking conveyor belt is operated and rotated by the driving mechanism to reduce the vertical height between the blanking point and the receiving point, so as to protect and smoothly collect the objects.

[0023] Preferably, the driving mechanism includes a second driving member, a cam connected to the second driving member, and a connecting rod connected to the cam, and the connecting rod is connected to the blanking conveyor belt.

[0024] By adopting the above technical solution, the cam-linkage mechanism is used to drive the deflection of the blanking conveyor belt to control the deflection angle of the blanking conveyor belt, and when the cam rotates one circle, the blanking conveyor belt also deflects a stroke, which is convenient for the subsequent blanking operation of the objects.

[0025] Preferably, the blanking mechanism further comprises an induction switch arranged on one side of the transition conveyor belt; wherein, when the induction switch receives an object signal, the driving mechanism drives the blanking conveyor belt to deflect.

[0026] By adopting the above technical solution, the induction switch can detect the object signal on the transition conveyor belt. After the transition conveyor belt is set to a certain length, the object signal can be accurately detected after the object is stably received and conveyed to realize the execution operation of precision blanking.

[0027] Preferably, it also includes a palletizing mechanism located at the output end of the blanking conveyor belt, and the palletizing mechanism includes:

[0028] A roller conveyor mounted on the frame and having a conveying direction perpendicular to the conveying direction of the blanking conveyor belt; and

[0029] A plurality of blanking boxes are used to receive objects outputted by the blanking conveyor belt. The blanking boxes are arranged on the roller conveyor at intervals and one of the blanking boxes is located at the output end of the blanking conveyor belt.

[0030] By adopting the above technical solution, the stacking mechanism is mainly used to collect the objects output from the blanking mechanism, and the blanked objects are collected uniformly in the blanking box, and the subsequent centralized inspection saves labor costs. When the roller conveyor is in motion, the blanking box can slide, which is convenient for the replacement and collection of the blanking box, so as to better realize the continuous operation of the equipment and improve production efficiency.

[0031] Preferably, the stacking mechanism further comprises a heavy sensor installed on a roller conveyor; wherein, when the weight of the blanking box is greater than a built-in threshold of the heavy sensor, the roller conveyor drives the blanking box to move.

[0032] By adopting the above technical solution, after the weighing sensor is set, the weight of the blanking box can be automatically detected to achieve an automatic conveying effect. When the roller conveyor is long enough, the number of blanking boxes can also be increased accordingly, reducing the manual operation of loading and unloading boxes and improving production efficiency.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. By setting up the diversion mechanism and the blanking mechanism, objects carrying metal foreign bodies can be removed and diverted, and at the same time, they can be collected in a centralized manner by combining with the stacking mechanism. There is no need to stop the machine during the removal and diversion operation, which effectively improves the inspection production efficiency;

[0035] 2. The first driving member drives the diverter plate to perform a stroke back and forth, and the second driving member adopts a cam connecting rod structure to drive the blanking conveyor belt to deflect a stroke to realize the continuous conveying operation of objects on the equipment. At the same time, the stacking mechanism uses a weighing sensor to detect the weight of the blanking box to realize the operation of automatically replacing the blanking box, which improves the overall degree of automation, enables objects to achieve continuous detection operations, and further improves the detection production efficiency.

[0043] The present application is further described in detail below in conjunction with the accompanying drawings.

[0044] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of this application. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0046] See also Figure 1 The embodiment of the present application discloses a split-flow removable needle detector, comprising a frame 1, a material conveyor belt 2 arranged on the frame 1, and a detection module 3. The detection module 3 is composed of an upper detection sensor and a lower detection sensor above the material conveyor belt 2, and divides the material conveyor belt 2 into an input section 21 and an output section 22. Objects enter the output section 22 from the input section 21 through the detection module 3.

[0047] The needle detector also includes a diverter mechanism 4 and a blanking mechanism 5, which are respectively arranged on both sides of the output section 22. The diverter mechanism 4 is electrically connected to the detection module 3. When an object carries a metal foreign body and passes through the detection module 3, the detection sensor is used to receive a metal foreign body signal and send an execution signal to the diverter mechanism 4. When the diverter mechanism 4 receives the execution signal, it removes the object from the output section 22 and diverts it to the blanking mechanism 5. The blanking mechanism 5 is used to collect the diverted objects from the device.

[0048] The blanking mechanism 5 includes a transition conveyor belt 51 and an adjacent blanking conveyor belt 52 . Objects enter the transition conveyor belt 51 in advance and are gradually conveyed to the blanking conveyor belt 52 , and the blanking conveyor belt 52 outputs the objects.

[0049] In the needle detector structure of this embodiment, a stacking mechanism 6 is also provided on the frame 1. The stacking mechanism 6 is located at the output end of the blanking conveyor belt 52 and is used to receive objects output by the blanking conveyor belt 52. The main structure includes a roller conveyor 61 installed on the frame 1 and a plurality of adjacent blanking boxes 62 on the roller conveyor 61. In particular, the conveying direction of the blanking conveyor belt 52 is perpendicular to the conveying direction of the roller conveyor 61, and one of the blanking boxes 62 is located at the output end of the blanking conveyor belt 52 for receiving objects. The roller conveyor 61 includes a plurality of rollers and a servo motor for driving the rollers to rotate. The plurality of rollers and the servo motor can be driven by a synchronous belt or a sprocket. The number of rotations of the roller can be controlled by the servo motor, thereby controlling the conveying stroke of the blanking box 62 to ensure that there is always a blanking box 62 at the output end of the blanking conveyor belt 52.

[0050] The stacking mechanism 6 also includes a heavy sensor installed on the roller conveyor 61. The heavy sensor can measure the weight of the blanking box 62 on the roller conveyor 61. When the weight of the blanking box 62 is greater than the built-in threshold of the heavy sensor, the servo motor works to drive several blanking boxes 62 to be transported, and the blanking boxes 62 at the output end of the blanking conveyor belt 52 are output from the stacking mechanism 6 by a slide, and the adjacent and empty blanking boxes 62 are transported to the output end of the blanking conveyor belt 52 for rapid replacement. When the roller conveyor 61 is long enough, the operation interval period of manually placing the blanking box 62 is longer, and the degree of automation is higher. The operator can conduct centralized inspection of metal foreign bodies in the output blanking boxes 62, thereby greatly improving production efficiency.

[0051] Combination Figure 2 The flow dividing mechanism 4 includes a seat body 41, a first driving member 42 and a swing arm 43 mounted on the seat body 41, and a flow dividing plate 44 connected to the swing arm 43. The first driving member 42 is connected to one end of the swing arm 43, and the swing arm 43 is rotatably connected to the seat body 41. When the first driving member 42 is actuated, the swing arm 43 can swing relative to the seat body 41 and synchronously drive the flow dividing plate 44 to move.

[0052] Shared Reference Figure 3 and Figure 4 , the diverter plate 44 includes an arc segment on one side, and one end of the arc segment can be driven by the first driving member 42 to switch back and forth between the conveying section and the transition conveyor belt 51. When the detection module 3 detects an object carrying a metal foreign body, the first driving member 42 drives the diverter plate 44 to swing from the output section 22 toward the side of the transition conveyor belt 51, and the diverter plate 44 blocks the conveyance of the object on the output section 22 and guides the diverter plate 44 to the transition conveyor belt 51, and then is rejected and output by the blanking mechanism 5. The diverter mechanism 4 does not move once, so that the diverter plate 44 swings back and forth between the output section 22 and the transition conveyor belt 51 once as a stroke. In this embodiment, the material conveyor belt 2 does not need to be stopped during the diversion and rejection operation, which does not affect the subsequent object detection work, thereby improving production efficiency.

[0053] In order to improve the smoothness of objects when being removed and diverted, the diverter plate 44 is also equipped with a plurality of rolling parts on the side surface facing the detection module 3, so that the objects can be more smoothly guided to the blanking conveyor belt 52 when they collide with the side of the diverter plate 44 and divert.

[0054] Shared Reference Figure 5 and Figure 6The blanking mechanism 5 also includes a driving mechanism 53, which is connected to the blanking conveyor belt 52 and is used to drive the output end of the blanking conveyor belt 52 to deflect relative to the input end, thereby reducing the drop between the output end and the blanking box 62 to reduce the collision of objects falling into the blanking box 62. The entire blanking conveyor is provided with a rotating shaft at the input end, and the blanking output end is a free end.

[0055] The driving mechanism 53 includes a second driving member 531 installed on the frame 1, a cam 532 connected to the second driving member 531, and a connecting rod 533 connected to the cam 532, and one end of the connecting rod 533 is connected to the transition conveyor belt 51. In this embodiment, when the driving mechanism 53 is not working, the transition conveyor belt 51 is in a horizontal state. When the driving mechanism 53 is working, the cam 532 rotates 180° and the transition conveyor belt 51 is in an extreme deflection position. When the cam 532 rotates 360°, the transition conveyor belt 51 is placed in a horizontal state again, so that it can quickly undertake the subsequent material dropping operation to improve more efficient production efficiency.

[0056] When the needle detector is working, objects are successively input from the input section 21 of the material conveyor belt 2 and enter the conveying section after passing through the detection module 3. When the detection module 3 detects metal foreign matter, the diverter mechanism 4 is actuated to drive the diverter plate 44 to swing back and forth for a stroke to remove the objects into the blanking mechanism 5. An induction switch is also installed on the transition conveyor belt 51. When the objects are diverted to the transition conveyor belt 51, the induction switch sends a signal to the drive mechanism 53, and the second drive member 531 works to drive the blanking conveyor belt 52 to deflect and transport them to the stacking mechanism 6; when the blanking box 62 receives a certain amount of objects, the roller conveyor 61 works to output one of the blanking boxes 62 for manual inspection.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
