Description

Technical Field

[0001] The present application relates to the technical field of logistics warehouses, and in particular to a device for storing small parcels on shelves. Background Art

[0002] With economic development, more and more individuals and companies are choosing eBay foreign trade as their entrepreneurial direction and career path, determined to sell Chinese-made products worldwide. At the same time, international parcels, a logistics method particularly suited to eBay foreign trade sellers, are becoming increasingly important and the preferred logistics method for many eBay foreign trade sellers. Small parcels weighing less than two kilograms, with the combined length, width, and height of the outer packaging less than 90 cm, and the longest side less than 60 cm, can be sent internationally via postal airmail. The international parcel management process is as follows: First, the driver delivers the goods, scans and weighs them, and then verifies the goods against the receipt and takes them into the warehouse, completing the initial parcel connection with the information system. Second, after the parcel information is entered, the order is managed, and the information system ensures efficient order fulfillment. International parcels must be packaged with appropriate materials. Except for a small number of soft, dry, and pressure-resistant items, solid corrugated cardboard or calcium plastic should be used for other items.

[0003] Due to weight and outer packaging requirements for international parcels, there are different sizes of international parcels within a certain range. When the driver delivers the goods to the warehouse and scans and weighs them, in order to separate objects of different sizes, manpower is often needed. On the one hand, this increases manpower input, and on the other hand, the separation rate is slow.

[0004] Although separators for separating objects of different sizes exist in the prior art, such as the one disclosed in the Chinese utility model with authorization publication number CN207042803U, entitled "Automatic Separator for Large and Small Objects," the object is placed on a supporting structure, which moves along with the conveying structure. When the object moves to a grid adapted to its size, the object falls from the grid, thereby achieving the purpose of separating the objects. Although this patent disclosure can separate objects of different sizes, it provides grids of different sizes on the supporting structure, with one object placed in each grid, and the grids are arranged horizontally in the same plane. Therefore, this patent disclosure is bulky and takes up too much space.

[0005] In the field of logistics and transportation, conveyor belts are often used to transport cargo packages. If used to transport a large number of cargo packages, the conveyor belt has a large span. If the cargo package is skewed at the conveyor belt entrance, the skew will gradually increase during transportation, which can easily cause the cargo package to fall off midway, affecting the normal transmission effect. For example, the Chinese utility model disclosed in the authorization publication number CN207738030U, entitled "Logistics Cargo Package Regular Arrangement Adjustment Mechanism", uses a roller brush propulsion shaft to correct the tilted cargo package to a certain degree. Then, under the action of the pulley shaping mechanism, it is regularized and kept moving in the middle of the conveyor belt. The pulley shaping mechanism can be elastically expanded within a certain range. Under the driving action of the pulleys on the left and right sides, the expansion degree of the pulley shaping mechanism can be constrained, thereby achieving the effect of shaping the cargo package. Although this patent publication can adjust the cargo package, it requires constant monitoring of the degree of tilt of the cargo package and frequent adjustment of the degree of expansion of the shaping mechanism, which is cumbersome, time-consuming and labor-intensive.

[0006] According to the Chinese invention patent with authorization announcement number CN108502430B, entitled "An Intelligent Storage Shelf Device for Logistics Warehousing", the first flip sorting mechanism and the second flip sorting mechanism transfer the goods on them to a two-way sorting conveyor belt by tilting and flipping themselves. Although this operation method can solve the problems of low efficiency of manual sorting and high labor intensity for workers, the tilting and flipping method makes it easy for the cargo packages to roll off the flip sorting mechanism, resulting in lost items.

[0022] The beneficial effects of this application are:

[0023] 1. The function of the separator is to hold mixed small packages. The feed port is used for feeding, and the unloading port is used for unloading. An unloading component is set at the unloading port. The function of the unloading component is to control the opening and closing of the unloading port to facilitate the unloading of mixed small packages individually. The upper rack and the lower rack have the function of bearing weight. The function of the first-level sorting port and the second-level sorting port is to classify the mixed small packages according to size. The function of the pushing component A and the pushing component B is to push the sorted small packages to the conveying mechanism. The function of the conveying mechanism is to transport the conveyed small packages. The sliding component A and the sliding component B are convenient for the small packages on the upper conveyor to slide due to inertia. The small parcels transferred from the conveying mechanism slide directly onto the transfer mechanism, and the upper turntable on the transfer mechanism rotates to rotate the small parcels to the storage shelf. The function of the limiting component A is to limit the small parcels to prevent the small parcels from falling off the tray A due to the centrifugal force generated by the rotation. A smooth strip is provided on the storage shelf to facilitate the small parcels to slide from one end of the storage shelf to the other end. The small parcels are neatly arranged on the entire storage shelf under the function of the smooth strip.

[0024] 2. The shape of the frame is the same as that of the unloading port, which is convenient for installation on the unloading port. The load-bearing frame has a load-bearing function for the cylinder and provides a place for the installation of the cylinder. The cylinder has a pushing function, pushing the upper cover plate to realize the opening and closing of the unloading port.

[0025] 3. The sorting port is set to be square, because most international parcels are made of corrugated cardboard boxes with calcium plastic, and the shape of the corrugated cardboard boxes is square. This application divides international parcels into two sizes, one with the longest side ranging from 30 cm to 60 cm, and the other is between 10 cm and 30 cm. The pushing component A has a pushing function, and the electric push rod has a telescopic function, which is convenient for pushing the push plate, and the push plate pushes the sorted parcels into the upper conveyor unit.

[0026] 4. The upper conveyor group in this application has the same structure as the lower conveyor group. The active conveyor and the driven conveyor are arranged in parallel in the same plane. One side of the belt on the active conveyor and the other side of the belt on the driven conveyor clamp the small packages to transport the small packages. The trustee A has a limiting function to prevent the spring A from tilting. The splint A can be extended and retracted under the action of the spring A, and the splint B can be extended and retracted under the action of the spring B. The splints A and B can be extended and retracted, and small packages of different sizes can be tightened. The function of the drive component is to provide power for the operation of the active conveyor and the driven conveyor.

[0027] 5. The function of the sliding component A is to facilitate the rapid transfer of the small package to the transfer mechanism, and to ensure that the small package does not tilt and continues to move along the trajectory on the conveying mechanism.

[0028] 6. The upper and lower ends of the upper turntable are convenient for receiving small packages. The shaft hole is used to install the rotating shaft. Motor B provides a constant power source for the rotation of the active turntable. The limit assembly A prevents the small package from escaping from tray A due to centrifugal force.

[0029] 7. The function of the groove is to facilitate the fixing of the spring. The height of the inclined portion close to the upper rack is lower than the height of the inclined portion away from the upper rack. When the small package slides onto tray A, the small package squeezes the inclined portion, and the inclined portion is subjected to force to compress the spring, and the small package passes through the inclined portion smoothly. When the small package slides onto tray A, the inclined portion prevents the small package from moving outward. When the small package needs to be released, the limit plate is pressed, and the limit plate controls the limit column to move downward, compressing the spring again. The inclined portion here is completely in the groove and is released under the action of spring D.

[0030] 8. The height of one end of the flow strip close to the transfer mechanism is greater than the height of the end away from the transfer mechanism, so that the small package can be smoothly moved from one end of the storage shelf to the other end.

[0031] 9. The separator of the present application is arranged in a vertical direction and does not take up too much space. One side of the belt on the active conveyor and the other side of the belt on the driven conveyor clamp the small package, which can prevent the small package from tilting during the transmission process. The limit component A limits the small package from escaping from the transmission mechanism, which can effectively prevent the loss of items. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The working principle of the conveying mechanism of the present application is as follows: the small packages falling from the separator are divided into two types, one is the small package with the longest side less than 60 cm and greater than 30 cm, and the other is the small package with the longest side less than 30 cm and greater than 10 cm. Taking the small package with the longest side of 45 cm as an example, the technical solution of the present application is explained. When the small package with the longest side of 45 cm falls, since the length of the longest side of the first-level sorting port is 30 cm, the small package is restricted on the upper rack, and the electric push rod is started, and the electric push rod drives the push plate to move to the upper conveyor group 11. Therefore, the upper conveyor group 11 includes an active conveyor and a driven conveyor. The active conveyor and the driven conveyor are in the same plane. The dynamic push rod pushes the small package to the side of the active conveyor belt corresponding to the side of the driven conveyor belt through the push plate. Since the longest side of the small package is 45 degrees, the small package can be pushed to the plywood A and plywood B. At this time, motor A is started, and the output shaft of motor A rotates to drive the active shaft to rotate. The rotation of the active shaft drives the active roller and the active pulley thereon to rotate. The rotation of the active roller drives the active conveyor belt to rotate. In addition, the rotation of the active pulley drives the driven shaft to rotate through the synchronous belt, and then drives the driven conveyor belt to rotate. Therefore, one side of the active conveyor belt and one side of the driven conveyor belt keep synchronous and stable movement, and finally move the small package from the starting end to the end of the upper conveyor unit.

[0049] When a small package with the longest side of 25 cm falls from the unloading port, it passes through the first-level sorting port and falls at the second-level sorting port. Therefore, the small package is confined to the lower rack and is pushed by the electric push rod to move the small package from the starting end to the end end of the lower conveyor group.

[0050] When the small package is released from the clamping of the conveying mechanism, due to inertia, the small package can quickly slide onto the transfer mechanism through the rotation of the sleeve.

[0051] See also Figure 8 and Figure 9: A separator 2 is provided at the beginning of the conveying mechanism 1. The separator 2 includes a bracket 21. A hopper 22 is provided on the bracket 21. The hopper 22 includes an upper end and a lower end. The upper end of the hopper 22 is a feed port, and the lower end of the hopper 22 is provided with an unloading port. An unloading assembly 23 is provided at the unloading port. The mixed small package enters the hopper 22 from the feed port at the upper end of the hopper 22 and lands on the conveying mechanism 1 through the unloading port. The unloading port of the hopper 22 is square. The unloading assembly 23 includes a frame 231, a support plate 232 and a cylinder 233. The frame 231 is It is square, and the frame 231 is fixedly connected to the unloading port. A load-bearing frame 234 is provided at the bottom of the frame 231, and a cylinder fixing seat is provided on the load-bearing frame 234. A cylinder 233 is provided on the cylinder fixing seat. The support plate 232 includes an upper cover plate 2321 and a lower connecting plate 2322. The cylinder barrel of the cylinder 233 is fixedly connected to the cylinder fixing seat, and the piston rod of the cylinder 233 is fixedly connected to the lower connecting plate 2322. The piston rod of the cylinder 233 is extended and retracted through the lower connecting plate 2322 to drive the upper cover plate 2321 to realize the opening and closing of the unloading port.

[0052] The working principle of the separator in this application is as follows: the separator is arranged from top to bottom, and small packages of two size ranges are mixed and placed in the hopper. The upper cover is driven to open and close the unloading port through the extension and contraction of the piston rod of the cylinder. When a small package is unloaded, the upper cover closes the unloading port, and the first-level sorting port and the second-level sorting port are used to determine whether the small package is placed on the upper rack or the lower rack. When the electric push rod pushes the small package to the conveying mechanism, the upper cover is opened to unload another small package. Therefore, the working time of the cylinder is intermittent.

[0054] The working principle of the transfer mechanism in the present application: Since the structure of the upper turntable and the lower turntable in the present application is the same, the working principle of the transfer mechanism is now explained with reference to the upper turntable. When the small package slides onto tray A through the sliding assembly, since the height of the inclined surface of the limiting column at one end close to the upper rack is less than the height of the inclined surface of the limiting column at one end away from the upper rack, due to inertia, the small package can easily move from the lower part of the inclined surface to tray A. When the small package presses over the inclined surface of the limiting column, the weight of the small package presses on the spring C, and the spring C is compressed, and the small package can easily slide onto tray A. After the small package slides over the limiting column, the spring C is released, and the small package is blocked by the relatively high inclined surface. At this time, the small package compresses the spring D, and the spring D is compressed. When the small package is restricted, the active turntable is rotated, and the tray A with the small package rotates to one end of the shelf. At this time, the limit plate is pressed, and the limit plate drives the limit column to move downward to compress the spring C. When the inclined portion is completely pressed into the groove, the small package is bounced toward the shelf under the action of the spring.

[0055] See also Figure 1 A storage shelf 4 is provided on one side of the transfer mechanism 3, which is disposed between the conveying mechanism 1 and the storage shelf 4. The storage shelf 4 includes a shelf 41, on which a flow bar 42 is provided at an angle. The flow bar 42 includes an upper flow bar 421 and a lower flow bar 422. After the upper turntable 31 rotates, the packets on the tray A 311 are released onto the upper flow bar 421 for storage. After the lower turntable 32 rotates, the packets on the tray B 321 are released onto the lower flow bar 422 for storage. The height of the flow bar 42 at the end closest to the transfer mechanism 3 is greater than that at the end farther from the transfer mechanism 3.

[0056] The working principle of the storage rack: a flow bar is set on the shelf, and the flow bar is set at an angle to facilitate the movement of small packages from one end of the shelf to the other end until the shelf is full of small packages.

[0057] For the sake of convenience, the longest dimension of the first-level sorting port in this application is set to 30 cm, and the longest dimension of the second-level sorting port is set to 10 cm. Therefore, the longest side of an international parcel is less than 60 cm. Therefore, international parcels are divided into two size ranges, one is a parcel with a longest side less than 60 cm but greater than 30 cm, and the other is a parcel with a longest side less than 30 cm but greater than 10 cm. Parcels less than 10 cm are handled separately and will not be described in detail here.

[0058] The working process of this application includes the following steps:

[0059] Step 1: Mix the two different packets together, which is called a mixed packet for convenience;

[0060] Step 2: Start the cylinder, which drives the upper cover plate to move, opens the unloading port, and stops the cylinder;

[0061] Step 3: The unloading port is opened, a small bag falls from the unloading port, the cylinder is started, and the cylinder moves in the opposite direction to close the unloading port;

[0062] Step 4: If the dropped parcel cannot pass through the first-level sorting port, it means that the longest side of the parcel is less than 60 cm and greater than 30 cm.

[0063] Step 5: Start the electric push rod, which pushes the parcel to the upper conveyor unit through the push plate. When the parcel moves to the clamping plate A and clamping plate B between the active conveyor belt and the driven conveyor belt, turn off the electric push rod, and then start the electric push rod again, and the electric push rod returns to the initial position;

[0064] Step six: The packet is transported to the transfer mechanism, and due to inertia, the packet slides toward the upper turntable through the action of the sliding assembly A;

[0065] Step 7: After the packet passes the limiting post, spring C recovers its deformation and limits the packet on tray A.

[0066] Step 8: Start motor B, which drives the small package to rotate until the small package corresponds to the storage shelf, and then turn off motor B;

[0067] Step 9: Press the limit plate again, and the limit plate drives the limit column to move downward. At this time, the small package moves toward the shelf under the action of spring D;

[0068] Step 10: Because the smooth strips on the shelf are tilted, the small package can be smoothly moved to the other end of the shelf;

[0069] Step 11: If the dropped parcel can pass through the first-level sorting port, it means that the longest side of the parcel is less than 30 cm and greater than 10 cm.

[0070] Step 12: Repeat steps 5 to 10 on the lower rack;

[0071] Step 13: Sort the small packages into categories and place them on different levels of storage shelves.

[0072] Technical features not described in this application can be achieved through or by adopting existing technologies and will not be elaborated here. Of course, the above description is not a limitation of this application, and this application is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of this application should also fall within the scope of protection of this application.
