Description

Technical Field

[0001] The present invention is a warehouse management system operation method based on a smart warehouse, belonging to the field of smart warehouses. Background Art

[0002] With the maturity of the Internet and digital technology, smart warehouses have emerged, so the transformation of the warehousing and logistics industry towards intelligence is imminent. The warehouse management system is one of the main components of a smart warehouse. The warehouse management system includes warehousing, storage, allocation, and outbound. In warehouse management, to ensure storage, items are generally packaged, and data on items to be stored must be collected to complete the data entry of items to be stored, which is convenient for subsequent management. Then, multiple items of the same specifications are mechanically stacked on pallets, and then the stacked pallets are transported into the warehouse;

[0003] In order to complete the data collection and stacking operations, a conveyor is generally used to transport the packaged items. During the transportation process, electronic equipment is used to collect data from the labels on the packaged items. The packaged items are then transported to the grabbing position, and then the robot grabs the packaged items and stacks the grabbed packaged items on the pallet.

[0004] However, when placing packaged items on the conveyor or using the conveyor to transport packaged items, the packaged items are prone to tilt. When the tilted packaged items are transported to the grabbing position, the packaged items are likely to tilt, causing the position of the packaged items at the grabbing position to shift, resulting in the robot being unable to effectively grab the packaged items. In addition, the robot is likely to cause contact damage to the packaging of the items, resulting in the inability to effectively put the packaged items into storage, which will affect the quality of warehouse management.

[0014] Furthermore, the conveying member includes two mounting plates, the two mounting plates are in parallel, the two mounting plates are symmetrically arranged at the upper end of the frame, and the mounting plates are arranged obliquely with the left side higher and the right side lower;

[0015] The two mounting plates are symmetrically mounted on the left end of the fixed plate, and a plurality of conveying rollers are equidistantly arranged in the middle between the two mounting plates, and the conveying rollers extend to the upper side of the mounting plates.

[0016] Further, the functional part comprises an inverted U-shaped frame, two mounting plates are respectively arranged at the lower ends of the two vertical parts of the inverted U-shaped frame, and a scanner is arranged at the middle part of the right end of the longitudinal part of the inverted U-shaped frame;

[0017] A function box is arranged in the inverted U-shaped frame, and the function box extends to the left side of the inverted U-shaped frame. An inclined plate with a left high and a right low tilt arrangement is installed at the left end of the function box, and the lower end surface of the inclined plate coincides with the lower end surface of the function box;

[0018] The function box is internally symmetrically rotatably connected with two longitudinally arranged function rollers, and the function rollers extend out of the lower side of the function box.

[0023] An operation method of a warehouse management system based on a smart warehouse comprises the following steps:

[0024] The first step is loading. First, pack the items and stick the data information label on the top of the package. Then, place the packed items on the top of the multiple conveyor rollers on the left. Under the weight of the packed items and the assistance of the conveyor rollers, the packed items will slide to the right.

[0025] The second step is top leveling. When the moving packaged items approach the inclined plate, the inclined plate will pre-process the top of the package of the items. Then the packaged items will contact the functional rollers, and the driving device, chain and two sprockets will be used to make the two functional rollers rotate synchronously. The rotating functional rollers will level the top of the package of the items on the one hand, and on the other hand, cooperate with the conveying rollers to make the packaged items move to the right at a uniform speed.

[0026] The third step is data collection. When the packaged items moving at a constant speed enter the scanner, the scanner will scan the label on the top of the item packaging and collect the corresponding data. The scanner will transmit the collected data to the terminal for warehouse management.

[0027] The fourth step is correction and positioning. After data collection, the packaged items continue to move to the right with the assistance of the conveying rollers. Then, the packaged items enter between the two correction plates with the assistance of the two guide plates to correct the packaged items. Then, the packaged items are brought into contact with the limit box. At this time, the repulsive force generated between the magnetic plate and the electromagnet, on the one hand, buffers the impact force generated between the packaged items and the limit box, and on the other hand, makes the moving packaged items pause. Then, the circuit of the electromagnet is disconnected to eliminate the repulsive force between the magnetic plate and the electromagnet. At this time, the packaged items continue to move to the right with the assistance of the weight of the packaged items and the conveying rollers, and the magnetic plate and the electromagnet are brought into contact with each other, thereby stopping the movement of the packaged items and completing the positioning of the packaged items.

[0028] The fifth step is stacking and warehousing. Use the robot to grab the located packaged items, then place the grabbed packaged items on the pallet and stack them. After completing the stacking operation on the pallet, use a forklift or other tools to transport the pallet stacked with multiple packaged items to the warehouse to complete the warehousing.

[0029] Beneficial effects of the present invention:

[0030] 1. Through two guide plates, the packaged items are guided between the two correction plates, so as to be corrected and made to contact the left end of the limit box, which can stop the moving packaged items. The repulsive force generated between the electromagnet and the magnetic plate will buffer the impact force generated between the packaged items and the limit box, which can protect the packaging of the items and effectively ensure the quality of the packaging of the items. Then, the packaged items are slowly moved to the right, and the limit box is automatically returned to its original position, so as to position the packaged items and realize positioning and correction of the packaged items, effectively reducing the probability of damage to the packaged items, ensuring the normal warehousing management of the packaged items, and improving the quality of warehouse management.

[0031] 2. Through the multiple conveying rollers arranged with higher left and lower right and the weight of the packaged items, the packaged items move to the right, realizing the automatic movement of the packaged items, effectively reducing the equipment cost, and effectively reducing the probability of tilting of the moving packaged items due to the vibration generated by the operation of the equipment, ensuring the subsequent normal data collection and other work, and improving the management effect.

[0032] 3. Use the adjusting screw to move the functional box up and down to a suitable height to meet the needs of leveling the packaging of items at different heights. It is highly practical, and the inclined plate can be used to press down the excessively raised top of the packaging of the item to complete the pre-processing of the packaging of the item.

[0033] 4. Through the second servo motor, sprocket and chain, the two functional rollers are rotated. The two rotating functional rollers will level the top of the packaging on the one hand, and on the other hand, in cooperation with the conveying roller, the packaged items move to the right at a uniform speed, so as to level the top of the packaging, avoid the label tilting due to the top of the packaging being lifted, resulting in ineffective data collection, effectively ensuring the accuracy of the collected data, effectively reducing the probability of manual data collection, and improving the efficiency of warehouse management. 5. The distance between the two correction plates is adjusted by using a bidirectional screw to meet the use of packaging items of different sizes, which is practical, and two laser sensors are used to collect the posture of the moving packaged items. Through the first servo motor and the bidirectional screw, the two correction plates are moved outward to the appropriate position, so that the moving packaged items can effectively enter between the two correction plates, and then the first servo motor and the bidirectional screw are used to move the two correction plates inward to the initial position, so as to achieve effective correction of the packaged items, effectively reduce the probability of stoppage of the packaged items, ensure the normal conveying of the packaged items, and improve work efficiency.

DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0046] Embodiment 1:

[0047] At present, when packaged items are stored in a smart warehouse, conveyors are generally used to transport the packaged items, and electronic devices are used to collect data on the packaged items during the transportation process to complete the data entry of the warehoused items and facilitate management. However, when the packaged items are transported by the conveyor, the conveyor will vibrate, and the vibration can easily cause the transported packaged items to tilt, resulting in the electronic equipment being unable to effectively collect data on the packaged items, thereby affecting the subsequent management effect.

[0048] In order to solve the above problems, Figure 1 , Figure 2 and Figure 3 As shown, a warehouse management system based on a smart warehouse is provided, comprising a rack 1, two parallel mounting plates 2 arranged in an inclined manner with the left side higher and the right side lower symmetrically arranged at the upper end of the rack 1, and the two mounting plates 2 are lifted and installed through the rack 1;

[0049] A plurality of conveying rollers 3 extending to the upper side of the mounting plate 2 are equidistantly rotated and set in the middle between the two mounting plates 2. The plurality of conveying rollers 3 are used in combination to realize the conveying operation. The two mounting plates 2 are symmetrically installed on the left end of the fixed plate 9, and the fixed plate 9 extends to the upper side of the conveying rollers 3. The fixed plate 9 and the mounting plate 2 are in a vertical state. The two mounting plates 2 are used in combination to realize the installation of the fixed plate 9.

[0050] When in use, the packaged articles are placed on the upper end of the conveying roller 3 located on the left. Since the plurality of conveying rollers 3 are arranged with the left side higher and the right side lower, the placed packaged articles are in an inclined state with the left side higher and the right side lower. Then, the packaged articles move to the right under the cooperation of their own weight and the conveying rollers 3.

[0051] It can realize the automatic movement of packaged items, effectively reduce equipment costs, and effectively reduce the probability of tilting of moving packaged items due to vibrations generated by equipment operation, ensure subsequent normal data collection and other work, and improve management effects.

[0052] Embodiment 2:

[0053] In the process of using multiple conveying rollers 3 to move the packaged items, a scanner 5 is generally used to scan the label adhered to the top of the item packaging, so as to collect the data information on the label, and then complete the collection of the item data, and transmit the collected data to the terminal for warehouse management. However, the top of the item packaging is prone to warping, which makes it more likely that the label adhered to the top of the item packaging will tilt. The tilted label will hinder the scanner 5 from performing effective scanning operations and affect the accuracy of the collected data. In order to ensure normal warehousing operations, it is generally necessary to first find out the items with erroneous data entry, and use a handheld device to manually scan the label on the item packaging, which increases the time for item warehousing and affects the efficiency of warehouse management.

[0054] In order to solve the above problems, Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, two mounting plates 2 are respectively arranged on the lower ends of the two vertical parts of the inverted U-shaped frame 4, and the mounting plates 2 and the inverted U-shaped frame 4 are in a vertical state. The two mounting plates 2 are used together to lift the inverted U-shaped frame 4, and a scanner 5 with a downwardly arranged scanning head is arranged on the middle of the right end of the longitudinal part of the inverted U-shaped frame 4. Through the scanner 5, data collection operations are performed on the moving packaged items;

[0055] The function box 44 extending to the left side of the inverted U-shaped frame 4 is set in the inverted U-shaped frame 4, and the inclined plate 41 whose lower end surface overlaps with the lower end surface of the function box 44 and is arranged in an inclined manner with the left side higher and the right side lower is installed on the left end of the function box 44, and the top of the packaging of the article is pre-processed by the inclined plate 41;

[0056] Two function rollers 442 extending from the lower side of the function box 44 and arranged longitudinally are symmetrically rotatably connected to the inside of the function box 44, and the movable part of the driving device whose fixed part is arranged at the rear end of the function box 44 and located in the inverted U-shaped frame 4 is connected to the shaft of one function roller 442, and the corresponding function roller 442 is driven to rotate by the driving device, and the driving device can adopt a second servo motor 441;

[0057] The two sprockets 45 are respectively engaged with the left and right walls inside the chain 46 located in the inverted U-shaped frame 4 and arranged on the front side of the function box 44, and the front ends of the shafts of the two function rollers 442 passing through the function box 44 are respectively connected to the two sprockets 45, and the chain 46 cooperates with the two sprockets 45 to make the two function rollers 442 rotate synchronously;

[0058] The vertically arranged adjusting screw 42 is rotatably connected to the upper end of the function box 44, and the adjusting screw 42 whose upper end passes through the longitudinal portion of the inverted U-shaped frame 4 is threadedly connected to the inverted U-shaped frame 4, and the upper and lower positions of the function box 44 are adjusted by adjusting the adjusting screw 42;

[0059] The two round rods 43 located on the front and rear sides of the adjusting screw 42 are symmetrically arranged on the upper end of the function box 44, and the two round rods 43 whose upper ends penetrate the longitudinal part of the inverted U-shaped frame 4 are slidably connected to the inverted U-shaped frame 4. The two round rods 43 are used together to guide the movement of the function box 44.

[0060] Before use, the adjusting screw 42 is rotated according to the height of the packaging of the article. Since the adjusting screw 42 is threadedly connected to the inverted U-shaped frame 4, the adjusting screw 42 rotates and moves up and down at the same time, thereby making the function box 44 move up and down to a suitable height, so as to meet the leveling of the packaging of articles of different heights, and the practicability is high;

[0061] When in use, the packaged articles are placed first, and move to the right with the assistance of multiple conveying rollers 3, and the package of the articles is first close to the inclined plate 41. When the top of the package of the articles is excessively warped, the inclined plate 41 presses down the warped top of the package of the articles, thereby completing the pre-processing of the package of the articles;

[0062] Then the package of the pre-treated article enters the bottom of the function box 44, and the function roller 442 comes into contact with the top of the package of the article, and the second servo motor 441 is started, thereby driving a corresponding function roller 442 to rotate, and the corresponding sprocket 45 to rotate, and the other sprocket 45 is rotated under the transmission of the chain 46, so that the other function roller 442 is rotated;

[0063] The two rotating functional rollers 442 can flatten the top of the packaged items on the one hand, and cooperate with the conveying roller 3 on the other hand to make the packaged items move to the right at a constant speed. Then the packaged items move at a constant speed under the scanner 5, and the scanner 5 is used to scan the label on the top of the packaged items and collect the corresponding data. The scanner 5 transmits the collected data to the terminal for warehouse management.

[0064] The top of the item packaging can be leveled to avoid the label tilting due to the top of the packaging rising up, which leads to ineffective data collection. This effectively ensures the accuracy of the collected data, effectively reduces the probability of manual data collection, and improves warehouse management efficiency.

[0065] Embodiment three:

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the electromagnet 91 located on the upper side of the conveying roller 3 is set on the left end of the fixing plate 9, and the fixing plate 9 is used to provide a mounting carrier for the fixing plate 9 and other components, and the frame-type protective member is set on the left end of the electromagnet 91, and then the right end of the magnetic plate 74 located on the upper side of the conveying roller 3 and the left end of the frame-type protective member are attached to each other, and through the frame-type protective member, the anti-magnetic plate 74 and the electromagnet 91 directly collide with each other, and the frame-type protective member can use a frame-type rubber pad, and the electromagnet 91 and the magnetic plate 74 are arranged to repel each other;

[0067] The limit box 7, which is located on the upper side of the conveying roller 3 and is arranged parallel to the mounting plate 2 and has its opening facing left, is installed on the left end of the magnetic plate 74. The limit box 7, on the one hand, provides a mounting carrier for the magnetic plate 74 and other components, and on the other hand, limits the moving packaged items. The bidirectional screw 76 arranged along the length direction of the limit box 7 is rotatably connected to the inside of the limit box 7.

[0068] Two light rods 71 ​​arranged in a transverse manner are symmetrically arranged on the right end of the limit box 7, and the two light rods 71 ​​whose right ends penetrate the fixed plate 9 are both slidably connected to the fixed plate 9, and the magnetic plate 74 and the electromagnet 91 are located between the two light rods 71. The two light rods 71 ​​are used in conjunction to guide the movement of the limit box 7;

[0069] The functional block 75 whose left end face overlaps with the left end face of the limit box 7 and is located on the upper side of the conveying roller 3 is set on the middle part of the lower end of the limit box 7. Through the functional block 75, the contact area between the limit box 7 and the packaging of the article is increased, and the packaging of the article can be protected. The guide rod 73 arranged in a transverse manner is installed on the middle part of the right end of the functional block 75, and then the guide rod 73 whose right end passes through the fixed plate 9 is slidably connected to the fixed plate 9. Through the guide rod 73, on the one hand, the movement of the functional block 75 is guided, and on the other hand, the connection strength between the limit box 7 and the fixed plate 9 is increased;

[0070] The first limiting plate 72 is set on the right end of the light rod 71, and the first annular protective member sleeved on the outer end of the light rod 71 and located on the right side of the fixed plate 9 is set on the left end of the first limiting plate 72. The first limiting plate 72 is used to prevent the light rod 71 from being separated from the fixed plate 9, and the first annular protective member is used to prevent the first limiting plate 72 from directly colliding with the fixed plate 9. The first annular protective member can be an annular rubber pad for protecting the first limiting plate 72.

[0071] The second limiting plate 731 is installed on the right end of the guide rod 73, and the second annular protective member sleeved on the outer end of the guide rod 73 and located on the right side of the fixing plate 9 is installed on the left end of the second limiting plate 731. The second limiting plate 731 is used to prevent the guide rod 73 and the fixing plate 9 from being separated, and the second annular protective member is used to prevent the second limiting plate 731 and the fixing plate 9 from colliding. For the protection of the second limiting plate 731, the second annular protective member can be an annular rubber pad;

[0072] Two correction plates 6 extending out of the left side of the limit box 7 and arranged horizontally are symmetrically slidably connected in the limit box 7, and the bidirectional screw 76 passing through the two correction plates 6 are respectively threadedly connected to the two correction plates 6. The two correction plates 6 are made to move relative to each other through the bidirectional screw 76, and two guide plates 61 which are arranged in a V-shaped state with the left width being wider and the right width being narrower, and are integrated with the correction plates 6 and located on the right side of the scanner 5 are respectively set on the left ends of the two correction plates 6. The moving packaged items can be guided by the guide plates 61.

[0073] Before use, the bidirectional screw 76 is rotated according to the width of the packaged items, so that the two correction plates 6 move relative to each other, and then the distance between the two correction plates 6 is adjusted to meet the use of packaged items of different sizes, which is practical.

[0074] When in use, the circuit of the electromagnet 91 is first turned on, so that a repulsive force is generated between the electromagnet 91 and the magnetic plate 74, and under the action of the repulsive force, the limit box 7 and other components move to the left to the limit position, and then the packaged items are placed, and move to the right with the assistance of multiple conveying rollers 3, and then the scanner 5 is used to collect data of the moving packaged items. After the data collection is completed, the packaged items continue to move to the right;

[0075] Then the moving packaged article enters between the two guide plates 61, and under the guidance of the two guide plates 61, enters between the two correction plates 6, so as to correct the packaged article, and then the moving packaged article contacts the left end of the limit box 7, so as to stop the moving packaged article;

[0076] In addition, the repulsive force generated between the electromagnet 91 and the magnetic plate 74 will buffer the impact force generated between the packaged items and the limit box 7, thereby protecting the item packaging and effectively ensuring the quality of the item packaging;

[0077] Then, the circuit of the electromagnet 91 is disconnected, so that the repulsive force between the electromagnet 91 and the magnetic plate 74 disappears, and then the packaged article slowly moves to the right under the action of its own weight and the conveying roller 3, and the limit box 7 and other components move to the right as the packaged article moves to the right, so that the limit box 7 automatically returns to its original position, thereby positioning the packaged article, and then the robot is used to effectively grasp the packaged article after positioning correction, and then the grasped packaged article is stacked;

[0078] It can realize the positioning and correction of packaged items, effectively reduce the probability of damage to packaged items, ensure the normal warehousing management of packaged items, and improve the quality of warehouse management.

[0079] Embodiment 4:

[0080] Two guide plates 61 are used to guide the packaged items into between the two correction plates 6 to correct the moving packaged items. However, when the posture angle of the moving packaged items is too large, the two guide plates 61 come into contact with the packaged items. At this time, the two guide plates 61 will block the packaged items, thereby increasing the probability of the packaged items stopping. In order to ensure normal warehousing operations, the packaged items are generally corrected manually, which will increase the transportation time of the packaged items and affect work efficiency.

[0081] In order to solve the above problems, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, two vertical plates 21 located between the inverted U-shaped frame 4 and the guide plate 61 are respectively set to the upper ends of the two mounting plates 2, and the laser sensor 22 located on the outer side of the conveying roller 3 is installed on the inner end of the vertical plate 21, and the vertical plate 21 is used to provide a mounting carrier for the laser sensor 22;

[0082] The fixed part of the first servo motor 8 is set to the rear end of the limit box 7, and the movable part of the first servo motor 8 is connected to the bidirectional screw 76. The bidirectional screw 76 is automatically driven to rotate by the first servo motor 8, and the front end of the bidirectional screw 76 extends out of the front side of the limit box 7 and is connected to the hand wheel 761. The bidirectional screw 76 is manually driven to rotate by the hand wheel 761.

[0083] Before use, the hand wheel 761 can be held and rotated to manually drive the bidirectional screw 76 to rotate, thereby causing the two correction plates 6 to move relative to each other, thereby completing the operation of adjusting the distance between the two correction plates 6;

[0084] When in use, the moving packaged article moves between the two laser sensors 22, and the two laser sensors 22 are used to collect the posture of the moving packaged article. If the posture angle of the moving packaged article is too large, the first servo motor 8 is started, and the bidirectional screw 76 is driven to rotate, so that the two correction plates 6 move outward to a suitable position;

[0085] This allows the moving packaged items to effectively enter between the two correction plates 6, and then the first servo motor 8 is used to cause the bidirectional screw 76 to rotate in the opposite direction, so that the two correction plates 6 move inward to the initial position, thereby achieving effective correction of the packaged items, effectively reducing the probability of shutdown of the packaged items, ensuring the normal transportation of the packaged items, and improving work efficiency.

[0086] An operation method of a warehouse management system based on a smart warehouse comprises the following steps:

[0087] The first step is loading. First, pack the items and stick the data information label to the upper end of the package. Then, place the packed items on the upper end of the multiple conveying rollers 3 on the left. Under the weight of the packed items and the assistance of the conveying rollers 3, the packed items will slide to the right.

[0088] The second step is top leveling. When the moving packaged article approaches the inclined plate 41, the inclined plate 41 will pre-process the top of the article packaging. Then the packaged article contacts the functional roller 442, and the driving device, the chain 46 and the two sprockets 45 are used to make the two functional rollers 442 rotate synchronously. The rotating functional rollers 442 will level the top of the article packaging on the one hand, and on the other hand, cooperate with the conveying roller 3 to make the packaged article move to the right at a uniform speed.

[0089] Step 3: Data collection: When the packaged items moving at a constant speed enter the scanner 5, the scanner 5 will scan the label on the upper end of the item packaging and collect the corresponding data, and the scanner 5 will transmit the collected data to the terminal for warehouse management;

[0090] The fourth step is correction and positioning. After data collection, the packaged items continue to move to the right with the assistance of the conveying roller 3. Then, the packaged items enter between the two correction plates 6 with the assistance of the two guide plates 61 to correct the packaged items. Then, the packaged items are brought into contact with the limit box 7. At this time, the repulsive force generated between the magnetic plate 74 and the electromagnet 91 can buffer the impact force generated between the packaged items and the limit box 7 on the one hand, and make the moving packaged items pause on the other hand. Then, the circuit of the electromagnet 91 is disconnected to make the repulsive force between the magnetic plate 74 and the electromagnet 91 disappear. At this time, the packaged items continue to move to the right with the assistance of the weight of the packaged items and the conveying roller 3, and the magnetic plate 74 and the electromagnet 91 are brought into contact with each other, thereby stopping the movement of the packaged items and completing the positioning of the packaged items.

[0091] Step 5: Stacking and warehousing: Use the robot to grab the positioned packaged items, place the grabbed packaged items on the pallet and stack them. After the stacking operation is completed on the pallet, use a forklift or other tool to transport the pallet stacked with multiple packaged items to the warehouse to complete the warehousing. Although this specification is described according to the implementation mode, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
