[0008] When no material is being conveyed in a certain conveying channel, the light-shielding component is in its natural position, blocking the photoelectric detection circuit, and the feeding module slides along the feeding guide rail to the feed end of the corresponding conveying channel; when material is being conveyed in a certain conveying channel, the material acts on the light-shielding component to make the light-shielding component be in an inclined position that avoids the photoelectric detection circuit; when all the conveying channels are being conveyed, the photoelectric detection circuit is turned on.
[0009] Furthermore, the photoelectric detection component includes a detection photoelectric sensor and a reflector, which are disposed opposite to each other on both sides of the conveyor line, forming the photoelectric detection loop between the detection photoelectric sensor and the reflector.
[0010] Furthermore, the detection photoelectric sensor and the reflector are connected by a rotating shaft, and the light-shielding component is rotatably connected to the rotating shaft.
[0011] Furthermore, the light-shielding member includes a first rotating part, a connecting part, and a second rotating part, wherein the first rotating part and the second rotating part are located at the upper end and the lower end of the connecting part, respectively.

[0018] This utility model brings at least the following beneficial effects:
[0019] This utility model provides a multi-channel material detection and replenishment device for a conveyor line, comprising: multiple conveying channels formed by multiple baffles, a photoelectric detection component, a shielding component, and a replenishment component. The photoelectric detection component is disposed on both sides of the conveyor line, the shielding component is disposed above the multiple conveying channels, and the replenishment component is disposed at the inlet end of the multiple conveying channels. The photoelectric detection component has a photoelectric detection circuit, the shielding component includes multiple light-shielding elements, and each conveying channel has one light-shielding element above it. The replenishment component includes a replenishment module and a replenishment guide rail, and the replenishment guide rail runs along the multiple conveying channels. The width of the conveying channel is set, and the feeding module slides in conjunction with the feeding guide rail. The feeding module has an arc-shaped guiding structure for allowing materials to enter the conveying channel. When no material is being conveyed in a certain conveying channel, the light-shielding member is in its natural position, blocking the photoelectric detection circuit, and the feeding module slides along the feeding guide rail to the feed end of the corresponding conveying channel. When material is being conveyed in a certain conveying channel, the material acts on the light-shielding member to make the light-shielding member be in an inclined position that avoids the photoelectric detection circuit. When all the conveying channels are being conveyed, the photoelectric detection circuit is activated.
[0020] Materials are conveyed on the conveyor line. When material is being conveyed in a certain conveyor channel, the material exerts a force on the light-blocking component above that channel, causing it to tilt at a certain angle and thus avoid the photoelectric detection circuit. If no material is being conveyed in a certain conveyor channel, the light-blocking component above that channel will remain in its natural vertical position, thus blocking the photoelectric detection circuit. The feeding module will then slide along the feeding guide rail to the feed end of that conveyor channel, and the material will enter the channel through the arc-shaped guide structure. Only when every conveyor channel of the conveyor line is being conveyed will the photoelectric detection circuit be activated, as each light-blocking component will be tilted at a certain angle, thus determining that the material is being conveyed normally on the conveyor line.
[0021] The multi-channel material detection device for conveyor lines has a simple overall structure and strong applicability. Its signal detection method based on optical reflection principles ensures high detection accuracy, superior precision, and better stability. It can accurately determine whether material is being conveyed simultaneously in each conveyor channel, effectively avoiding misjudgments and missed detections caused by external interference, thus ensuring the normal operation of the conveyor line and maintaining normal production efficiency. Furthermore, the replenishment component can automatically replenish materials to conveyor channels that are short of material, saving manpower and ensuring production efficiency.

[0039] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0040] Example 1
[0041] In automated production lines, multiple channels of material often enter the conveyor simultaneously. Existing material detection devices use contact-based detection, requiring complex mechanical structures and corresponding electrical control systems, resulting in low detection accuracy and poor applicability. Furthermore, existing material detection devices struggle to accurately detect materials from multiple channels simultaneously, and are susceptible to external interference leading to misjudgments, impacting normal production efficiency. When a material shortage is detected in a particular channel, manual intervention is required to replenish the material, consuming manpower and disrupting production continuity.
[0042] In view of this, the present invention provides a multi-channel material detection and replenishment device for a conveyor line, comprising: multiple conveying channels 500 formed by multiple baffles 400, a photoelectric detection component 100, a shielding component, and a replenishment component. The photoelectric detection component 100 is disposed on both sides of the conveyor line, the shielding component is disposed above the multiple conveying channels 500, and the replenishment component is disposed at the feeding end of the multiple conveying channels 500. The photoelectric detection component 100 has a photoelectric detection circuit, the shielding component includes multiple light-shielding elements 200, and a light-shielding element 200 is disposed above each conveying channel 500. The replenishment component includes a replenishment module 310 and a replenishment guide rail 320. The feeding module 310 is slidably engaged with the feeding guide rail 320 along the width direction of multiple conveying channels 500. The feeding module 310 has an arc-shaped guide structure 330 for allowing materials to enter the conveying channel 500. When there is no material conveying in a certain conveying channel 500, the light-shielding member 200 is in the natural position of blocking the photoelectric detection circuit, and the feeding module 310 slides along the feeding guide rail 320 to the feeding end of the corresponding conveying channel 500. When there is material conveying in a certain conveying channel 500, the material acts on the light-shielding member 200 to make the light-shielding member 200 be in an inclined position that avoids the photoelectric detection circuit. When there is material conveying in all conveying channels 500, the photoelectric detection circuit is turned on.
[0043] Materials are conveyed on the conveyor line. When material is being conveyed in a certain conveyor channel 500, the material exerts a force on the light-blocking member 200 above the conveyor channel 500, causing the light-blocking member 200 to tilt at a certain angle, thereby avoiding the photoelectric detection circuit. If no material is being conveyed in a certain conveyor channel 500, the light-blocking member 200 above the conveyor channel 500 will be in its natural vertical position, thus blocking the photoelectric detection circuit. The feeding module 310 will slide along the feeding guide rail 320 to the feeding end of the conveyor channel 500, and the material will enter the conveyor channel 500 through the arc-shaped guide structure 330. Only when every conveyor channel 500 of the conveyor line is being conveyed will the photoelectric detection circuit be activated because each light-blocking member 200 is tilted at a certain angle, thus determining that the material is being conveyed normally on the conveyor line.
[0044] The multi-channel material detection device for the conveyor line has a simple overall structure and strong applicability. Its signal detection method based on optical reflection principles ensures high detection accuracy, superior precision, and better stability. It can accurately determine whether each conveyor channel 500 is simultaneously conveying material, effectively avoiding misjudgments and missed detections caused by external interference, thus ensuring the normal operation of the conveyor line and maintaining normal production efficiency. Furthermore, the replenishment component can automatically replenish materials to conveyor channels 500 that are short of material, saving manpower and ensuring production efficiency.
[0045] In an optional embodiment, the photoelectric detection component 100 includes a detection photoelectric sensor 110 and a reflector 120. The detection photoelectric sensor 110 and the reflector 120 are disposed opposite each other on both sides of the conveyor line, and a photoelectric detection loop is formed between the detection photoelectric sensor 110 and the reflector 120.
[0046] Please see Figure 1 In this embodiment, the reflector 120 is fixedly installed on the leftmost side of the conveyor line, and the detection photoelectric sensor 110 is fixedly installed on the rightmost side of the conveyor line. The connection between the detection photoelectric sensor 110 and the reflector 120 forms the photoelectric detection loop. The light emitted by the detection photoelectric sensor 110 is reflected back to the detection photoelectric sensor 110 after being reflected by the reflector 120. When the photoelectric detection loop is blocked, it indicates that the light-blocking member 200 above a certain conveyor channel 500 is in its natural vertical position, and it can be determined that at least one conveyor channel 500 is not conveying material.
[0047] In an optional embodiment, the detection photoelectric sensor 110 and the reflector 120 are connected by a rotating shaft 300, and the light-shielding member 200 is rotatably connected to the rotating shaft 300.
[0048] Please continue reading Figure 1 The rotating shaft 300 is positioned above the conveyor line, and the light-shielding component 200 is rotatably mounted on the rotating shaft 300. The distance between the bottom of the light-shielding component 200 in its natural position and the conveyor channel 500 is less than the height of the material to be tested, thereby effectively enabling the light-shielding component 200 to switch between its vertical natural position and its tilted position at a certain angle.
[0049] In an optional embodiment, the light-shielding member 200 includes a first rotating part 210, a connecting part 220, and a second rotating part 230, with the first rotating part 210 and the second rotating part 230 located at the upper and lower ends of the connecting part 220, respectively.
[0050] Please see Figure 2 The first rotating part 210, the connecting part 220, and the second rotating part 230 are integrally connected. The connecting part 220 is disposed on the rotating shaft 300. The second rotating part 230 rotates under the force of the material, and the first rotating part 210 and the second rotating part 230 rotate synchronously. Assuming that... Figure 2 The material is conveyed from left to right. The first rotating part 210 and the second rotating part 230 will rotate counterclockwise by a certain angle under the action of the material to reach an inclined position that does not block the photoelectric detection circuit.
[0051] In an optional embodiment, the mass of the first rotating part 210 is less than the mass of the second rotating part 230.
[0052] The advantage of this design is that when there is no material being conveyed on the conveying channel 500, the light-blocking component 200 can be stably positioned in a vertical position, and when the last material on the conveying channel 500 passes through the light-blocking component 200, the light-blocking component 200 can rotate back to a vertical position, thus improving the accuracy of the detection.
[0053] In an optional embodiment, a damping reset structure for restoring the light-shielding member 200 to its natural position is provided between the connecting part 220 and the second rotating part 230.
[0054] The damping reset structure enables the light-shielding component 200 to always tend to return to its natural vertical position when there is no material force, further improving the accuracy of detection; at the same time, the damping reset structure also enables the light-shielding component 200 to always rotate within a certain angle range, improving the reliability of the device.
[0055] In an optional embodiment, the baffles 400 are arranged along the conveying direction of the conveyor line, and a conveying channel 500 is formed between two adjacent baffles 400.
[0056] Please see Figure 1 Multiple baffles 400 are arranged in parallel at intervals to divide the conveyor line into multiple conveyor channels 500, and a light-shielding element 200 is set above each conveyor channel 500.
[0057] In an optional embodiment, a fixed frame 600 is provided above the conveyor line, and the baffle 400 is slidably connected to the fixed frame 600 through an adjustment structure.
[0058] Please see Figure 3 The fixed frame 600 and the baffle 400 are perpendicular to each other. A chute is provided in the middle of the fixed frame 600. The baffle 400 can slide along the chute to adjust the width of the conveying channel 500 to accommodate the conveying of different types of materials.
[0059] Specifically, the adjustment structure includes a slider 700, a fastener 800, and a rotating handle 900. The slider 700 is connected to the baffle 400 via the fastener 800. The slider 700 is slidably engaged with the fixed frame 600. The rotating handle 900 is rotatably located outside the fastener 800.
[0060] Please continue reading Figure 3The baffle 400 has a protruding rib on its top, and a slider 700 is slidably mounted on the fixing frame 600. The slider 700 and the rib are connected and fixed by a fastener 800. A rotating handle 900 is provided on the outside of the fastener 800 for tightening or loosening the fastener 800. When it is necessary to adjust the width of the conveyor channel 500, first manually rotate the rotating handle 900 to loosen the fastener 800, then adjust the position of the slider 700 and the baffle 400, and finally manually rotate the rotating handle 900 to tighten the fastener 800. The operation is simple.
[0061] In an optional embodiment, the feeding assembly further includes a feeding motor 340 for driving the feeding module 310, and the feeding motor 340 is signal-connected to the light-shielding member 200 above each conveying channel 500.
[0062] Please see Figure 4 When a conveyor channel 500 is empty, the light-shielding component 200 above that conveyor channel 500 will be in its natural position, blocking the photoelectric detection circuit. The light-shielding component 200 sends a signal to the feeding motor 340, causing the feeding motor 340 to drive the feeding module 310 to move to the feeding end of the conveyor channel 500. The material enters the conveyor channel 500 through the arc-shaped guide structure 330, thus completing the feeding.
[0063] In an optional embodiment, a counting photoelectric sensor 350 is provided above the feeding module 310, and the counting photoelectric sensor 350 is signal connected to the feeding motor 340.
[0064] Please see Figure 4 The counting photoelectric sensor 350 can count the material fed into the conveying channel 500. When the count reaches the full material setting value, the counting photoelectric sensor 350 sends a control signal to the feeding motor 340, so that the feeding motor 340 drives the feeding module 310 to leave the feeding end of the conveying channel 500.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
