[0010] In some embodiments, the variable distance driving mechanism comprises a gantry, a first driving motor and a ball screw pair, wherein the gantry comprises a support and a cross beam; the support is fixed to the two sides of the bottom plate respectively, and the two ends of the cross beam are fixed to the support; the two ends of the screw in the ball screw pair are fixed to the support and located below the cross beam, the nut in the ball screw pair is sleeved on the screw and connected with the support plate; the first driving motor is fixed to the lower surface of the bottom plate, and the main shaft of the first driving motor is connected with one end of the screw through a transmission belt.
[0011] In some embodiments, the replenisher comprises two variable distance assemblies arranged at the goods outlet and the goods inlet of the goods channel respectively; and the replenisher further comprises a first detection part arranged outside the goods channel and used to detect the variable distance of the second side plate.
[0012] In some embodiments, the stopper is a door plate assembly comprising a door plate and a door plate driving mechanism, the door plate being movably arranged at the goods outlet and being used to control the opening and closing of the goods outlet under the action of the door plate driving mechanism.

When the goods are delivered, the pressing wheel can be rotated under the action of the rotating driving mechanism. In this way, the goods in the goods channel can be moved out of the delivery opening relying on the rotating friction of the pressing wheel. This way can accurately control the replenishment rhythm. Only when the pressing wheel rotates a fixed length (for example, the length of the goods), the current goods can be pushed out, and the next goods can be controlled to be stationary in the goods channel, so that the phenomenon of multiple goods and goods jamming can be effectively reduced.

[0030] The names of the messages or information exchanged between the devices in the embodiments of the present disclosure are only for illustrative purposes and are not intended to limit the scope of these messages or information.
[0031] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0032] Figure 1 shows a structural schematic diagram of some embodiments of a replenisher of the present disclosure. As shown in FIG. 1, the replenisher includes a compression roller assembly 100, a variable distance assembly 200, a door panel assembly 300, and a detection component 400 at a product outlet. Figure 1As shown, the replenisher can include a goods channel assembly 1, a stopper 2 and a pressure roller assembly 3. Here, the goods channel assembly 1 can include a bottom plate 11 and two side plates 12. The two side plates 12 can be spaced apart on the upper surface of the bottom plate 11 and extend along the length direction of the bottom plate 11, so as to form a goods channel for accommodating goods. Here, one end of the goods channel is usually an inlet, and the other end of the goods channel is usually an outlet. That is, the goods enter the goods channel from the inlet and move out of the goods channel from the outlet. Here, the upper surface is usually a surface away from the ground during work, opposite to the lower surface. It can be understood that the two side plates 2 can be fixedly connected with the bottom plate 1, so as to form a goods channel with a fixed width. Here, the fixed manner of the side plates with the bottom plate is not limited, for example, a clamping groove can be formed on the bottom plate, or an L-shaped angle iron is used for fixation, etc.
[0033] Here, the stopper 2 can be arranged at the outlet, for blocking the outlet. In this way, under the blocking effect of the stopper 2, the goods can be kept in the goods channel. The structure of the stopper 2 here can be set according to actual requirements. As an example, the stopper 2 can include a baffle and a telescopic driving component. The bottom plate 11 can be provided with a stop groove near the outlet. In this case, the baffle can be arranged in the stop groove and hinged to the bottom plate at the end away from the outlet. Meanwhile, one end of the telescopic driving component is connected with the baffle, and the other end is connected with the lower surface of the bottom plate. In this way, when the telescopic driving component is elongated, the baffle can be erected in the goods channel, so as to block the outlet. When the telescopic driving component is retracted, the baffle can be laid down and completely embedded in the stop groove, so as to stop blocking and form a flat goods channel.
[0034] It can be understood that the replenisher of the present disclosure can open the baffle (i.e., close the outlet) when the goods are taken. In this way, after the goods enter the goods channel of the replenisher in sequence, the goods can be restricted in the goods channel by the baffle, so as to avoid the goods from falling off from the outlet.
[0035] Further, the pressure roller assembly 3 can include a pressure roller 31, a lifting driving mechanism and a rotating driving mechanism. The lifting driving mechanism 32 can be used to control the height of the pressure roller 31 from the goods channel. The rotating driving mechanism can be used to control the rotation of the pressure roller 31. Here, the pressure roller 31 can be fixed on the side plate through a connecting piece. From the above, it can be seen that a fixed beam 41 can be arranged above the position of the goods channel near the outlet. Alternatively, the pressure roller 31 can also be arranged at the outlet through the fixed beam 41. Figure 1
[0036] It should be noted that when the replenisher takes goods, i.e. in the process of goods entering the replenisher, the stopper can block the outlet, and the pressure roller 31 is lifted, so that the goods in the goods channel are arranged in turn from the outlet. When replenishing the goods shelf, the pressure roller 31 can be pressed on the first goods in the goods channel under the action of the lifting driving mechanism, and the stopper stops shielding. At this time, the goods in the goods channel can be stationary in the goods channel by the pressure of the pressure roller 31, so as to avoid the situation that the goods fall from the goods channel after the stopper stops shielding. When the goods are taken out, the pressure roller 31 can be rotated under the action of the rotating driving mechanism. In this way, the goods in the goods channel can be moved out of the outlet by the rotating friction of the pressure roller 31. This way can accurately control the replenishment rhythm, only need to rotate the pressure roller by a fixed length (such as the length of the goods), the current goods can be pushed out, and the next goods can be controlled to be stationary in the goods channel, so as to effectively reduce the phenomenon of goods out of stock and goods jam.
[0037] It can be understood that the specific structure of each component in the replenisher of the present disclosure can be set according to actual needs. In some embodiments, as shown in Figure 2A and 2B , the lifting driving mechanism can include a rotating driving component 321, a cam 322 and a swing arm 323. Among them, the rotating driving component can include but is not limited to a rudder, a motor or a motor, etc. Here, the cam 322 can be fixed on the main shaft of the rotating driving component 321, and the convex surface of the cam 322 can abut with the swing arm 323 in the rotating process. One end of the swing arm 323 can be hinged with the fixed beam 41, and the other end can be fixed with the rotating driving mechanism and the pressure roller 31. In this way, the swing arm 323 can be controlled to rise and fall with the rotation of the cam 322, so as to realize the height adjustment of the pressure roller 31.
[0038] As an example, the rotating driving component 321 and the cam 322 can be installed below the swing arm 323. For example, the rotating driving component 321 can be installed on the side plate or the support of the gantry shown in the figure. At this time, when the convex surface of the cam 322 abuts with the swing arm 323, the swing arm 323 will rise accordingly. When the cam 322 rotates from the convex surface to the non-convex surface, the swing arm 323 will fall accordingly.
[0039] Alternatively, the rotating driving component 321 and the cam 322 can also be installed above the swing arm 323. As Figure 2A and 2BAs shown, the rotation drive component 321 can be fixed to the fixed beam 41 via a mounting plate. Here, the swing arm 323 can be L-shaped, and the swing arm is hinged to the fixed beam at the Z-angle. The pressure roller 31 can be fixed to the long side end of the swing arm 323, and an abutment roller 33 is provided at the short side end of the swing arm 323. The cam 322 can control the lifting and lowering of the swing arm by contacting the abutment roller 33. Thus, when the protruding surface of the cam 322 contacts the abutment roller 33, the abutment roller 33 moves away from the outlet around the hinge axis of the swing arm 323, while simultaneously raising the long side of the swing arm. Conversely, it moves the abutment roller 33 closer to the outlet around the hinge axis of the swing arm 323, while simultaneously lowering the long side of the swing arm.
[0040] In some applications, the lifting drive mechanism can also use cylinders and connecting rods. The cylinder can also be fixed to the side plate or fixed beam via a mounting plate, with the cylinder's piston rod facing the cargo channel. The piston rod is fixed to the pressure roller and the rotary drive mechanism via a connecting rod. Thus, the downward and upward movement of the pressure roller can be controlled by the extension and retraction of the piston rod.
[0041] In addition, to improve the reliability of the pressure roller in pressing down on the goods, a counterweight 34 can be fixed to the aforementioned swing arm 323, thereby increasing the pressure of the pressure roller. The weight, material, and fixing method of the counterweight are not limited. It should be noted that the rotary drive mechanism and pressure roller in this embodiment can use a small integrated motor similar to a hub motor. This reduces space occupation while meeting usage requirements. Furthermore, a high-friction wheel sleeve (e.g., a rubber wheel) can be fitted onto the outer side of the pressure roller 31, thereby increasing the contact friction.
[0042] In some embodiments, to broaden the applicability of the replenishment device to accommodate goods of various sizes, the first side plate (e.g., ...) of the two side plates of the replenishment device disclosed herein... Figure 1 The middle right side plate can be fixed to the base plate 11, while the second side plate (such as...) Figure 1 The middle left side plate can be movably connected to the base plate 11. In this case, the replenisher may also include at least one pitch-changing assembly 4. Figure 3A and 3B As shown, the pitch-changing assembly 4 may include a support plate 42 and a pitch-changing drive mechanism. Here, the support plate 42 can be fixed to the second side plate. Thus, under the action of the pitch-changing drive mechanism, the second side plate can be moved away from or closer to the first side plate to control the width of the cargo passage.
[0043] As an example, the variable distance driving mechanism can include a gantry 431, a first driving motor 432 and a ball screw pair 433. The gantry 431 can include a support and a crossbeam. The support can be fixed on both sides of the bottom plate 11, and the two ends of the crossbeam can be fixed on the support. That is, the gantry is arranged above the goods channel. It can be understood that, in order to simplify the structure of the device, the crossbeam here can be reused as the fixed beam 41 described above, that is, the crossbeam and the fixed beam can be the same component. Here, the two ends of the screw in the ball screw pair 433 can be fixed on the support and below the crossbeam 41. In addition, the nut in the ball screw pair 433 can be sleeved on the screw and connected with the support plate 42. The first driving motor 432 can be fixed on the lower surface of the bottom plate 11, and the main shaft of the first driving motor can be connected with one end of the screw through a transmission belt 434. In this way, not only the accuracy of variable distance movement can be ensured, but also interference with the goods in the goods channel can be avoided.
[0044] Optionally, a guide block can be arranged on the support plate. At the same time, a guide groove can be formed on the bottom plate. The variable distance driving mechanism can be a pneumatic cylinder arranged in the bottom plate close to one side of the second side plate. That is, the second side plate is located between the pneumatic cylinder and the first side plate, so as to avoid affecting the goods in the goods channel. In order to realize the variable distance movement of the second side plate, the piston rod of the pneumatic cylinder can be directed towards the second side plate and connected with the support plate. In this way, through the extension and retraction movement of the piston rod, the second side plate can be driven to move, so as to realize the adjustment of the width of the goods channel.
[0045] It can be understood that the replenishment device of the present disclosure can be provided with a variable distance assembly at the middle position of the goods channel. Optionally, in order to improve the variable distance efficiency and stability, the replenishment device can also include two variable distance assemblies. The two variable distance assemblies can be arranged at the delivery opening and the feeding opening of the goods channel respectively. That is, the two variable distance assemblies are structurally the same but arranged at different positions, and are located at the two ends of the replenishment device respectively. The two variable distance assemblies each have a drive, which can be controlled synchronously to drive the variable distance side plate (second side plate) to move.
[0046] It should be noted that, when the replenishment device takes goods, the second side plate can be moved to a certain position as needed, so as to be able to accommodate goods of a corresponding specification. After the goods are taken, the second side plate can also be moved inward (i.e. in the direction close to the first side plate) to clamp the goods, so as to play a role of arranging, so that the goods in the goods channel are arranged neatly. Then, the second side plate can be moved outward (i.e. in the direction away from the first side plate) by a small distance, so as to leave a small gap with the goods. In this way, when replenishing goods to the goods shelf, the goods can also play a guiding role.
[0047] In some embodiments, the stop 2 described above can be a door panel assembly. The door panel assembly can include a door panel 21 and a door panel drive mechanism. The door panel 21 is movably disposed at the outlet of the cargo channel. Under the action of the door panel drive mechanism, the door panel 21 can be moved, thereby controlling the opening and closing of the outlet.
[0048] As an example, such as Figures 4A to 4C As shown, the bottom end of the door panel 21 can be hinged to the end of the base plate 11 located at the loading port, and a mounting plate 23 is provided on the lower surface of the door panel 21. Here, the door panel driving mechanism can include a second drive motor 221, a convex ball 222, and an elastic element 223. The second drive motor 221 can be fixed to the lower surface of the base plate 11. The convex ball 222 can be disposed at the end of the main shaft of the second drive motor 221. At the same time, the convex ball 222 can be connected to the mounting plate 23 through the elastic element 223. In this way, by the telescopic movement of the main shaft of the second drive motor 221, the door panel 21 can be controlled to flip, thereby realizing the opening and closing of the loading port.
[0049] like Figure 4A As shown, when the door panel 21 needs to be opened, the main shaft of the second drive motor 221 can retract inward. In this state, the convex ball 222 and the mounting plate 23 are usually separated. At this time, the mounting plate 23 can be pulled by the elastic element 223, thereby driving the door panel 21 to open. That is to say, the complete opening of the door panel 21 mainly relies on the pulling force of the elastic element. Figure 4B As shown, when the door panel 21 needs to be closed, the main shaft of the second drive motor 221 can extend outward. In this state, the convex ball 222 contacts the mounting plate 23 and pushes the mounting plate 23 to move away from the base plate, thereby causing the door panel 21 to close.
[0050] It is understood that the door panel drive mechanism disclosed herein adopts a non-contact drive, which can effectively reduce damage to the hinges and door panel, and the drive direction is linear, compact and saving installation space. Specifically, through the combination of the elastic element 223 and the convex ball 222 in the structure, the opening and closing of the door panel can be more linear and smooth, avoiding damage to the hinge joint when closing in the case of a rigid connection. The elastic element can have a pre-tensioned tension. This provides tension to ensure the door panel fully opens and engages with the loading channel when opening, and also helps the convex ball maintain stable contact with the mounting plate during closing. This structural design occupies little space, provides stable opening and closing, and has a long service life.
[0051] As described above, to enable the door panel to open and close, the mounting plate 23 typically cannot be a flat, smooth surface. As shown in the figure, the mounting plate usually has multiple (at least two) planes with different angles. The angle between the plane fixed to the door panel and the plane connected to the convex ball is typically greater than 90° and less than 180°. Furthermore, the elastic element can be customized according to actual needs, such as a spring, rubber strip, elastic band, etc. In some embodiments, to ensure the stability of the door panel's opening and closing movement and extend the service life of the elastic element, as shown in the figure, the elastic element 223 can be mounted on both sides of the convex ball 222 via a fixing plate 224. The fixing plate 224 is located between the convex ball 222 and the second drive motor 221.
[0052] Furthermore, such as Figure 4D As shown, a flange 211 can be formed at the top of the door panel 21. The width of the flange 211 can be smaller than the width of the aisle on the connecting shelf. That is, the width of the flange 211 should be smaller than the width of the narrowest aisle on the shelf. This design is to accommodate the connection of aisles of different widths. Figure 4D As shown, when connecting to the narrow aisle H1 (the upper part of the diagram), the flange can serve as a support for the connecting aisle; when connecting to the wide aisle H2 (the lower part of the diagram), although there is a small gap at the overlap, it will not affect the safe passage of goods. If this design is not adopted, and a uniform width is used at the front end, if the uniform width is the same as the wide aisle, the door panel will not be able to connect properly when connecting to the narrow aisle due to the obstruction of the aisle side panel (the black line in the diagram indicates the aisle side panel for guidance). If designed according to the narrow aisle width, the connection will be incomplete when connecting to the wide aisle, and wider goods are prone to falling. At the same time, since the entire replenishment unit does not have a mechanism for moving towards or away from the shelf, the door panel can be designed to be longer. This allows a small portion of the flange to extend into the aisle opening when connecting to the shelf. That is, when the door panel is opened and connected to the shelf, the flange on the door panel can extend into the aisle of the shelf, as shown by the dotted line in the diagram. This also better adapts to the deformation of the shelf aisle, making the connection more stable.
[0053] In some embodiments, such as Figure 4CAs shown, the replenisher disclosed herein may also be provided with an outer cover 24. Here, the outer cover 24 can be installed on the lower surface of the base plate and arranged around the door panel drive mechanism. This can protect the mechanism. In addition, to ensure the stability of the door panel's flipping movement, a limit support 25 can also be provided at the delivery port. The limit support 25 can be used to limit the opening position of the door panel 21 and to support the opened door panel 21. That is, under the tension of the elastic element and the action of the support, the door panel can be stably positioned in the open position, connecting with the bottom plate of the shelf aisle and linking the replenisher aisle with the shelf aisle. It is understood that the aforementioned limit support 25 can be installed on the lower surface of the base plate at the delivery port or on the aforementioned outer cover 24.
[0054] In some alternative implementations, the second drive motor can also be fixed to the upper surface of the base plate and located on one side of the outlet. The main shaft of the second drive motor is fixedly connected to one side of the door panel. Simultaneously, the base plate can be provided with a guide groove at the outlet that matches the bottom of the door panel. The extension direction of the guide groove is perpendicular to the length direction of the base plate. Thus, as the main shaft of the second drive motor extends and retracts, it can drive the door panel to move left and right along the guide groove, thereby achieving the opening and closing control of the outlet. Optionally, the second drive motor can also be located above the outlet, with the main shaft connected to the top of the door panel. Thus, as the main shaft extends and retracts, it can also drive the door panel to move up and down, thereby achieving the opening and closing control of the outlet.
[0055] In some embodiments, to ensure the accuracy of the movement of each mechanism, the replenishment device of this disclosure may also be equipped with various detection components. For example, such as... Figure 5 As shown, a first detection component 51 can be installed outside the cargo channel to detect the change distance of the second side plate, such as calibrating the movement distance or zeroing of the second side plate. The first detection component 51 can be fixed on the base plate or on the gantry frame, with the detection head facing the second side plate.
[0056] For example, a second detection component 52, a third detection component 53 and a fourth detection component 54 can also be arranged at the position of the delivery opening. The second detection component 52 can be used to detect the opening and closing state of the door panel, such as detecting whether the door panel is closed in place. The second detection component 52 can be fixed on the side plate (such as the first side plate) or the bottom plate, and the detection head faces the door panel. The third detection component 53 can be used to detect the information of the goods passing through the delivery opening, such as detecting whether the goods are stuck, and can also be used for goods counting. The third detection component 53 can also be arranged on the bottom plate, or can also be arranged on the side of the door panel facing the delivery opening when the door panel is closed, and the detection head is perpendicular to the moving direction of the goods. The fourth detection component 54 can be used to detect the information of the goods channel of the docking goods shelf, such as verifying whether the information in the goods channel is accurate, whether it needs to be replenished, etc. The fourth detection component 54 can be arranged on the side of the door panel away from the delivery opening when the door panel is closed, and the detection head faces the top end of the door panel. In this way, when the door panel is opened and docked with the goods shelf, the detection head of the fourth detection component will face the goods channel of the goods shelf, so as to detect through the gap between the door panel and the goods channel of the goods shelf.
[0057] It can be understood that the detection methods of the above detection components can also be set according to actual needs. For example, the first and second detection components can adopt proximity switches. The third detection component can adopt a photoelectric sensor. And the fourth detection component 54 can adopt a distance measuring sensor. In the case that the door panel is opened, the detection light can enter the goods channel of the goods shelf to detect the distance of the goods in the goods channel. In this case, the sensor can always monitor the distance data, so as to prevent the deformation of the goods channel and other problems from causing inaccurate detection and further causing false replenishment.
[0058] Some embodiments of the present disclosure also provide a replenishment system. As shown in Figure 6 , the replenishment system can include a goods shelf 61, at least one replenisher 62 and a moving mechanism 63. As can be seen from Figure 6 , a plurality of goods channels for storing goods can be arranged on the goods shelf 61. A goods taking mechanism 64 can be arranged between two goods shelves, so that the goods can be taken from the front side of the goods shelf. The moving mechanism 63 can be arranged at the rear side of the goods shelf 61. The moving mechanism 63 can be used to drive the replenisher 62 to move in the width direction and the height direction of the goods shelf 61. At least one replenisher 62 can be installed on the moving mechanism 63, which is used to replenish goods to the goods channels on the goods shelf. The replenisher herein can adopt the replenisher structure described in any of the implementation manners of the above embodiments. And the height of the delivery opening of the replenisher is lower than the height of the delivery opening, so that the goods in the goods channel can slide along the goods channel under the action of its own gravity, without the need to additionally set a driving mechanism, which simplifies the equipment structure and reduces the equipment cost.
[0059] It should be noted that the structure of the moving mechanism 63 is not limited. For example, the moving mechanism can include a horizontal traveling mechanism and a lifting mechanism. The horizontal traveling mechanism can include a horizontal rail and a traveling trolley. The lifting mechanism can be fixed on the traveling trolley. The replenisher can be installed on the lifting mechanism. In this way, the moving mechanism can drive the replenisher to move along the surface of the shelf and be lifted. Therefore, the replenisher can reach the replenishing position of any goods channel on the shelf.

Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or equivalent features without departing from the above utility model concept. For example, the above features and the technical features disclosed in the embodiments of the present disclosure (but not limited to) with similar functions are replaced with each other to form a technical solution.
