Description

Technical Field

[0001] This utility model relates to the field of logistics technology, specifically to a color mark sensing device for positioning a four-way shuttle. Background Technology

[0002] With the rapid development of e-commerce, logistics, and other industries, the demands on the efficiency of warehousing systems are increasing. Four-way shuttles, as a highly efficient automated warehousing device, can move freely in the horizontal and vertical directions of the shelves, enabling rapid storage and retrieval of goods. Color-coded sensors, a commonly used positioning method, can accurately locate the shuttle by recognizing color-coded marks on the shelves or tracks.

[0003] A search revealed a utility model patent with Chinese patent publication number CN215003942U, which discloses a color mark sensor, including a fixing component. A color mark sensor assembly is mounted on the fixing component. The fixing component includes a mounting plate with a groove on its side wall and multiple symmetrically arranged locking holes around the inner wall of the groove. The color mark sensor assembly includes a color mark sensor body with a connecting housing on its side wall. A first sliding hole is provided at the end of the connecting housing away from the color mark sensor body. Springs are symmetrically arranged on the inner wall of the connecting housing, and each spring is connected to a moving plate at its end away from the inner wall of the connecting housing.

[0004] As mentioned above, the external optical lens of the color mark sensor plays a particularly important role. However, in actual use, dust inevitably accumulates on the lens surface. An increase in this dust may affect the focusing effect of light, thereby affecting the detection accuracy, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a color mark sensing device for positioning a four-way shuttle vehicle, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a color mark sensing device for positioning a four-way shuttle, comprising a color mark sensor (preferably an OMRON E3Z-LS81, capable of accurately identifying minute color differences, which is crucial for the accurate identification of color mark positions on shelves during the operation of the four-way shuttle, ensuring precise positioning and navigation of the shuttle), a light-transmitting component installed on the outside of the color mark sensor, the light-transmitting component including a miniature stepper motor fixedly installed on the top outer wall of the color mark sensor, a mounting bracket coaxially fixed to the output end of the miniature stepper motor, two lenses fixedly installed inside the mounting bracket, a rubber sleeve fixedly fitted to the outside of the photosensitive end opening of the color mark sensor, one of the bottom lenses being in contact with the rubber sleeve, and a wiping structure installed on the top of the color mark sensor, the wiping structure including a support plate and a protective sleeve.

[0007] As a further preferred embodiment of this technical solution, the support plate is fixedly installed on the top outer wall of the color mark sensor by a bracket, the protective sleeve is fixedly sleeved on the outside of the support plate, and one of the lenses at the top is attached to the protective sleeve.

[0008] When dust adheres to the outer lens of the sensor's photosensitive end, a clean lens can be directly driven to replace it. During the repositioning process, the dust can also be cleaned. The micro stepper motor on the top of the color mark sensor is activated, and the mounting bracket is driven to rotate half a turn. The positions of the two lenses inside the mounting bracket will alternate, allowing the color mark sensor to quickly start working. As the lens with dust on the bottom moves upward, it will come into contact with the outer wall of the bottom of the protective cover. The dust will be wiped clean by the protective cover, and the lens will always be in contact with the outer wall of the protective cover, which can prevent dust from adhering to the surface of the top lens.

[0009] As a further preferred embodiment of this technical solution, a connecting assembly is installed on one side of the outer wall of the color mark sensor. The connecting assembly includes a plug frame fixedly connected to the outer wall of one side of the color mark sensor. A vertically arranged limiting groove is opened inside the plug frame. Two symmetrically arranged limiting blocks are slidably connected inside the limiting groove. A limiting cover is slidably fitted outside the plug frame. A receiving groove adapted to the limiting block is opened on the top and bottom inner walls of the limiting cover.

[0010] As a further preferred embodiment of this technical solution, an extension block is fixedly connected to one side of the outer wall of each of the two limiting blocks, and a vertically arranged spring is fixedly connected to the top outer wall of each of the two extension blocks. Two vertical grooves are opened on one side of the outer wall of the insertion frame, and the top ends of the two springs are respectively fixedly connected to the two vertical grooves.

[0011] As a further preferred embodiment of this technical solution, the plug-in frame is internally threaded with a horizontally arranged lead screw, one end of which is rotatably connected to a top plate. The top plate is in contact with the inner wall of one side of the limiting groove, and two rollers are rotatably connected inside the top plate. The two rollers are respectively in contact with the outer walls of the two limiting blocks.

[0012] Grasp the color mark sensor and insert its external connector frame into the groove of the limiting cover. Under the restriction of the limiting cover, the connector frame and the color mark sensor cannot wobble. Then, drive the screw to rotate by the knob. Since the top plate is attached to the inner wall of the limiting groove and cannot rotate, it will move along the limiting groove under the push of the screw. The two limiting blocks will be pushed away from each other and then inserted into the two receiving slots respectively, which can prevent the connector frame from coming out of the limiting cover.

[0013] As a further preferred embodiment of this technical solution, a protective ring is fixedly connected inside the outer bracket of the support plate, and the protective ring surrounds the outside of the light-transmitting component.

[0014] As a further preferred embodiment of this technical solution, the mounting bracket is externally fixedly connected to two covers, one of which is attached to the outer wall of the protective sleeve. The top of the outer wall of the protective ring is fixedly connected to a cover, which covers the outside of the top lens.

[0015] As a further preferred embodiment of this technical solution, a number of equally spaced cleaning protrusions are provided on the bottom of the outer wall of one end of the protective sleeve.

[0016] This utility model provides a color mark sensing device for positioning a four-way shuttle, which has the following advantages:

[0017] (1) By setting a light-transmitting component, this utility model can directly drive a clean lens to replace the external lens of the sensor when dust is attached to it. In addition, the dust can be cleaned during the repositioning process. The micro stepper motor on the top of the color mark sensor is started, and the mounting bracket is driven to rotate half a circle. The positions of the two lenses inside the mounting bracket will be alternated, so that the color mark sensor can be put into operation quickly. The lens with dust attached at the bottom position will contact the outer wall of the bottom of the protective cover during the upward movement. The dust will be wiped clean by the protective cover. The lens will always be in contact with the outer wall of the protective cover, which can prevent dust from adhering to the surface of the top lens.

[0018] (2) By setting a connecting component, the color mark sensor is grasped and its external plug-in frame is inserted into the groove of the limiting cover. Under the restriction of the limiting cover, the plug-in frame and the color mark sensor cannot shake. Then, the screw is driven to rotate by the knob. The top plate cannot rotate because it is attached to the inner wall of the limiting groove. Therefore, under the push of the screw, it will move along the limiting groove. The two limiting blocks will be pushed away from each other and then inserted into the two receiving grooves respectively, which can prevent the plug-in frame from falling out of the limiting cover.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, a color mark sensing device for positioning a four-way shuttle includes a color mark sensor 1. A light-transmitting component 4 is installed on the outside of the color mark sensor 1. The light-transmitting component 4 includes a miniature stepper motor 402 fixedly installed on the top outer wall of the color mark sensor 1. A mounting bracket 401 is coaxially fixed to the output end of the miniature stepper motor 402. Two lenses 403 are fixedly installed inside the mounting bracket 401. A rubber sleeve 3 is fixedly fitted on the outside of the light-sensing end opening of the color mark sensor 1. One lens 403 at the bottom is in contact with the rubber sleeve 3. A wiping structure is installed on the top of the color mark sensor 1. The wiping structure includes a support plate 404 and a protective sleeve 405.

[0026] The support plate 404 is fixedly installed on the top outer wall of the color mark sensor 1 by a bracket, and the protective sleeve 405 is fixedly sleeved on the outside of the support plate 404. A lens 403 at the top is attached to the protective sleeve 405.

[0027] When the micro stepper motor 402 on top of the color mark sensor 1 is activated, the mounting bracket 401 is driven to rotate half a turn. The positions of the two lenses 403 inside the mounting bracket 401 will alternate, allowing the color mark sensor 1 to quickly start working. As the lens 403 with dust on it moves upward, it will come into contact with the outer wall of the bottom of the protective cover 405. The dust will be wiped clean by the protective cover 405, and the lens 403 will always be in contact with the outer wall of the protective cover 405, which can prevent dust from adhering to the surface of the top lens 403.

[0028] like Figure 3 and Figure 4As shown, a connecting component 5 is installed on one outer wall of the color mark sensor 1. The connecting component 5 includes a plug frame 501 fixedly connected to the outer wall of one side of the color mark sensor 1. A vertically arranged limiting groove 502 is opened inside the plug frame 501. Two symmetrically arranged limiting blocks 503 are slidably connected inside the limiting groove 502. A limiting cover 504 is slidably sleeved on the outside of the plug frame 501. A receiving groove 505 adapted to the limiting block 503 is opened on the top and bottom inner walls of the limiting cover 504.

[0029] An extension block 508 is fixedly connected to one side of the outer wall of each of the two limiting blocks 503. A vertically arranged spring 509 is fixedly connected to the top outer wall of each of the two extension blocks 508. Two vertical grooves are opened on one side of the outer wall of the insertion frame 501. One end of the top of each of the two springs 509 is fixedly connected to the inside of the two vertical grooves. When the extension block 508 is no longer under pressure, the spring 509 can drive it back into the limiting groove 502, which facilitates the disassembly of the device.

[0030] The plug frame 501 has a horizontally set lead screw 506 internally threaded. One end of the lead screw 506 is rotatably connected to a top plate 507. The top plate 507 is in contact with the inner wall of one side of the limiting groove 502. The top plate 507 has two rollers 510 rotatably connected inside. The two rollers 510 are respectively in contact with the outer walls of the two limiting blocks 503.

[0031] Grasp the color mark sensor 1 and insert its external insertion frame 501 into the groove of the limiting cover 504. Under the restriction of the limiting cover 504, the insertion frame 501 and the color mark sensor 1 cannot shake. Then, drive the screw 506 to rotate by the knob. The top plate 507 cannot rotate because it is attached to the inner wall of the limiting groove 502. Therefore, under the push of the screw 506, it will move along the limiting groove 502. The two limiting blocks 503 will be pushed away from each other and then inserted into the two receiving grooves 505 respectively, which can prevent the insertion frame 501 from coming out of the limiting cover 504.

[0032] like Figure 1 As shown, a protective ring 2 is fixedly connected inside the outer bracket of the support plate 404. The protective ring 2 surrounds the outside of the light-transmitting component 4, which can prevent the light-transmitting component 4 from being damaged by collision.

[0033] like Figure 1 and Figure 2 As shown, the mounting bracket 401 is externally fixedly connected to two covers 407. One of the covers 407 is attached to the outer wall of the protective sleeve 405. The top of the outer wall of the protective ring 2 is fixedly connected to a cover 6. The cover 6 covers the outside of the top lens 403. The cover 6 can prevent dust from adhering to the back of the lens 403. The cover 407 can prevent dust from adhering to the protective sleeve 405.

[0034] like Figure 2As shown, a number of equally spaced cleaning protrusions 406 are provided on the bottom of the outer wall of one end of the protective sleeve 405. When the lens 403 passes through the cleaning protrusions 406, the protrusions will fit the lens 403 more closely when compressed, which is conducive to improving the cleaning effect. The dust will also be intercepted and prevented from being carried upward.

[0035] This utility model provides a color mark sensing device for positioning a four-way shuttle vehicle, and its specific working principle is as follows:

[0036] The installation process is as follows: First, fix the limiting cover 504 to the outer wall of the shuttle car to ensure that the color mark sensor 1 is facing the external color mark when it is fixed. Then, grasp the color mark sensor 1 and insert its external plug frame 501 into the groove of the limiting cover 504. Under the restriction of the limiting cover 504, the plug frame 501 and the color mark sensor 1 cannot shake. Then, drive the screw 506 to rotate by the knob. The top plate 507 cannot rotate because it is attached to the inner wall of the limiting groove 502. Therefore, under the push of the screw 506, it will move along the limiting groove 502. The two limiting blocks 503 will be pushed away from each other and then inserted into the two receiving grooves 505 respectively. This can prevent the plug frame 501 from coming out of the limiting cover 504. The disassembly process is also relatively convenient.

[0037] When dust adheres to the lens 403 on the outside of the photosensitive end of the color mark sensor 1, the micro stepper motor 402 on the top of the color mark sensor 1 is activated, and the mounting bracket 401 is driven to rotate half a turn. The positions of the two lenses 403 inside the mounting bracket 401 will alternate, so that the color mark sensor 1 can quickly start working. As the lens 403 with dust on the bottom moves upward, it will come into contact with the bottom outer wall of the protective sleeve 405. The dust will be wiped clean by the protective sleeve 405, and the lens 403 will always be in contact with the outer wall of the protective sleeve 405, which can prevent dust from adhering to the surface of the top lens 403.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
