Description

Technical Field

[0001] This application relates to the field of warehousing equipment technology, and in particular to a conveying device for rail travel. Background Technology

[0002] In existing technologies, handling devices are primarily powered by built-in batteries to enable their handling and movement functions. However, the battery capacity is limited, and when the battery level is low, the handling device returns to a charging station for recharging. During charging, the handling device cannot continue handling operations, reducing the overall efficiency of the warehousing system's inbound and outbound processes.

[0003] To reduce or even eliminate the time required for the transport device to return to the charging station for recharging, the current solution involves installing intermittent charging units along both the main and auxiliary roadways, with the charging units interrupted at the intersection of the main and auxiliary roadways. When the transport device travels within the main and auxiliary roadways, its fixed charging receiver works in conjunction with the charging units to receive power.

[0004] However, when the transport device of this scheme travels along the main aisle, the charging receiver needs to go through the process of disconnecting and reconnecting with the charging component every time it passes an intersection. This seriously affects the travel speed and charging efficiency of the transport device. The collision between the charging receiver and the charging component during reconnection also leads to more electrical sparks and a reduction in the lifespan of parts. Utility Model Content

[0005] The technical solution adopted by this application to solve the above-mentioned technical problems is as follows:

[0006] A transport device for rail travel, comprising:

[0007] The vehicle body has a continuous enclosure around its perimeter, and a forklift mechanism is provided above the enclosure. The forklift mechanism is configured to extend to the outside of the enclosure.

[0008] A lifting mechanism, wherein the fork-taking mechanism is disposed above the lifting mechanism, and is used to realize the raising and lowering of the fork-taking mechanism;

[0009] A charging receiver is disposed on the lower surface of the conveying device, and the charging receiver is energized in conjunction with a charging component disposed along the extension direction of the first channel.

[0010] Preferably, the device includes multiple charging receivers, which are spaced apart along the travel direction of the transport device. During the travel of the transport device, at least one charging receiver cooperates with the charging component to receive power.

[0011] Preferably, the surrounding enclosure forms a receiving cavity, and the lifting mechanism is disposed within the receiving cavity. When the fork-lifting mechanism extends, the lifting mechanism is located within the receiving cavity.

[0012] Preferably, the fork-taking mechanism includes a fixing part and a fork-taking part, and the lifting mechanism is disposed below the fork-taking part and configured to extend out to the outside of the enclosure part along with the fork-taking part.

[0013] Preferably, the enclosure portion has a notch corresponding to the position of the fork portion, and the notch is used to avoid the extension of the fork portion.

[0014] Preferably, a support portion is also provided above the enclosure portion. When the forklift mechanism is lowered to the lowest position, the forklift mechanism is not higher than the support portion. When the forklift mechanism is raised to the highest position, the forklift mechanism is higher than the support portion.

[0015] Preferably, the fork-taking mechanism includes two forks, which are disposed on both sides of the bearing portion. Each fork includes a fixing portion and a fork-taking portion. The fork-taking portion is configured to extend to the outside of the enclosure portion, and the relative position of the fixing portion and the bearing portion remains unchanged.

[0016] Preferably, the fork-taking mechanism is a multi-segment telescopic structure.

[0017] Preferably, the fork-taking mechanism extends to the outside of the enclosure via a telescopic mechanism. The telescopic mechanism includes a drive screw and a nut sleeved on the drive screw, and the fork-taking mechanism is fixedly connected to the nut.

[0018] Preferably, the forklift mechanism extends to the outside of the vehicle body in the length direction.

[0019] Beneficial effects: By setting continuous enclosures around the perimeter and installing forklift mechanisms that can extend outside the vehicle body above the enclosures, the handling equipment can move goods without having to travel under them. At the same time, a charging receiver is installed so that the handling device can receive power through the charging components and the charging receiver while traveling in the aisle, so as to power the four-way shuttle. This ensures that the handling device can work continuously without having to return to the charging station to recharge, thus improving the overall working efficiency of the handling device.

[0030] First, this application relates to a power supply system for a handling device, wherein the handling device 100 is used in a storage system including a warehouse. In particular, the power supply system of this application allows the handling device 100 to leave the aisle and return to the aisle for charging. Determining whether the handling device 100 needs charging, and at what location, is beyond the scope of this application.

[0031] The warehousing system according to this application includes a warehouse and a handling device 100. The warehouse includes several first aisles (or main aisles) and a greater number of second aisles (or secondary aisles), and the handling device 100 needs to travel in the first and second aisles of the warehouse and move goods to the desired location.

[0032] See Figure 1-6 The conveying device 100 provided in this application embodiment includes:

[0033] The vehicle body has a continuous enclosure 110 around its perimeter, and a forklift mechanism 120 is provided above the enclosure 110. The forklift mechanism 120 is configured to extend to the outside of the enclosure 110.

[0034] The lifting mechanism 140 is provided above the fork-taking mechanism 120, which is used to raise and lower the fork-taking mechanism 120.

[0035] A charging receiver 510 is disposed on the lower surface of the conveying device 100, and the charging receiver 510 cooperates with a charging component 520 disposed along the extension direction of the first channel to receive power.

[0036] In this application, the continuous enclosure 110 surrounds the vehicle body into a rectangle, which forms a relatively enclosed space. The control elements, power supply and other connecting components of the transport device 100 are all located in this enclosed space. The lower part of the vehicle body is equipped with wheels for traveling on the lane 200.

[0037] The forklift mechanism 120, located above the enclosure 110, can extend outside the enclosure 110. This allows the transport device 100 to move away from the storage location 300 without having to travel below it. The forklift mechanism 120 extends below the storage location 300, and then the lifting mechanism 140 operates to lift the forklift mechanism 120, thereby lifting the transported object above the lifting mechanism 140 away from the storage location 300. Then, the forklift mechanism 120 performs a retraction action. When the forklift mechanism 120 retracts to above the enclosure 110, the lifting mechanism 140 performs a descent operation, lowering the forklift assembly to its initial position. Then, the transport device 100 moves to transport the transported object to the corresponding location.

[0038] See Figure 7 In this application, the charging component 520 is installed along the extension direction of the first aisle of the warehouse. The charging component 520 can be installed continuously or intermittently. In one possible embodiment, the charging component 520 is composed of an induction coil. The induction coil needs to be protected by an outer casing. Therefore, the charging component 520 can be installed in the first aisle in an intermittent manner. In addition, the handling device 100 travels along the first aisle to handle goods most of the time. As it travels along the first aisle, the charging receiver 510 and the charging component 520 cooperate to receive power most of the time. In another possible embodiment, the charging component 520 can be installed in both the first and second aisles. When the handling device 100 moves from the first aisle to the second aisle, it can still cooperate to receive power. If it cannot cooperate to receive power during the transfer from the first aisle to the second aisle, the energy storage device can provide power.

[0039] In this application, the charging receiver 510 is disposed on the conveying device 100, specifically on the bottom surface of the conveying device 100. When the conveying device 100 travels over the charging component 520, it can supply power to the conveying device 100 or the energy storage device by means of power reception.

[0040] The induction receiver must be flush with the bottom surface of the conveying device 100, or extend vertically downwards from the bottom surface, to ensure that it can work properly when powered.

[0041] When the handling device 100 travels in the aisle, the charging receiver 510 and the charging component 520 are powered. When needed, it can leave the aisle to perform handling tasks, such as moving goods in and out of a warehouse.

[0042] Furthermore, in order to ensure that the inductive charging unit can better cooperate with the inductive receiver to receive power during the operation, the transport device 100 is provided with multiple charging receivers 510. During the operation of the transport device 100, at least one charging receiver 510 cooperates with the charging component 520 to receive power.

[0043] See Figure 2-6 The forklift mechanism 120 of this application includes a fixed part 121 and a supporting part 130. The fixed part 121 is disposed above the enclosure part 110. The forklift part 122 is slidably connected to the fixed part 121. During the extension and retraction process, the relative position of the fixed part 121 and the enclosure part 110 remains unchanged, and only the forklift part 122 extends outward along the fixed part 121.

[0044] The fixed part 121 and the fork-taking part 122 can be slidably connected by a telescopic mechanism. In one possible embodiment, the sliding mechanism can be a screw and nut structure, with a transmission screw and a nut sleeved on the transmission screw. The fork-taking mechanism 120 is fixedly connected to the nut. The screw is fixedly set on the fixed part 121 or the enclosure part 110. Under the drive of the drive source, the screw rotates. Since one end of the screw is fixed, the relative position of the screw will not change. The nut sleeved on the screw moves when the screw rotates to a position, thereby driving the fork-taking part 122 fixed to the nut to move, realizing the extension of the fork-taking mechanism 120.

[0045] In another possible embodiment, the telescopic structure can also be a sliding groove and a transmission sprocket. A rotating wheel is provided at each end of the fixed part 121. A transmission belt is sleeved on the outside of the two rotating wheels. The transmission belt is fixedly connected to the fork-taking part 122. At least one of the two rotating wheels is a driving wheel. The rotation of the driving wheel drives the transmission belt to rotate, thereby driving the fork-taking part 122 above to move, thereby realizing the telescopic extension of the fork-taking mechanism 120.

[0046] In a possible embodiment of this application, the forklift mechanism 120 is a multi-segment telescopic structure. Because the length of the vehicle body is matched with the width of the track in the automated warehouse, the setting process will affect the storage density of the automated warehouse. If the setting is too short, it will be impossible to pick up goods. Therefore, when the forklift mechanism 120 is multi-segment telescopic, the extension length will be greater than the length of the vehicle body, which can move objects from a distance with a small vehicle body size.

[0047] As is conceivable, the length of the forklift mechanism 120 is generally the same as the length of the vehicle body. However, for some larger goods, it is necessary to adapt to both the width of the aisle 200 and the large size of the object being transported. Therefore, in one possible embodiment of this application, the forklift mechanism 120 extends to the outside of the vehicle body in the length direction, that is, the length of the forklift mechanism 120 is greater than the length of the vehicle body. This allows the transport device 100 to travel on a narrower track and provides a larger carrying area for the transport device 100 to carry large-volume objects.

[0048] In this application, the lifting mechanism 140 is used to lift the forklift mechanism 120. Therefore, the position of the lifting mechanism 140 can be adjusted according to different usage scenarios. In one possible embodiment, the surrounding enclosure 110 forms a receiving cavity, and the lifting mechanism 140 is disposed in the receiving cavity. When the forklift mechanism 120 extends, the lifting mechanism 140 is located in the receiving cavity.

[0049] When the lifting mechanism 140 is located within the accommodating cavity, only the fork-lifting part 122 of the fork-lifting mechanism 120 extends out, and the object to be transported is supported on the fork-lifting part 122. This is suitable for transporting lighter objects. For heavier objects, the strength of the fork-lifting mechanism 120 can be increased to accommodate heavier weights. However, if the strength that the fork-lifting mechanism 120 can increase reaches its maximum and still cannot bear the weight of the object to be transported, another possible embodiment can be adopted: the lifting mechanism is located below the fork-lifting part 122 and is configured to extend out to the outside of the enclosure part 110 along with the fork-lifting part 122.

[0050] The lifting mechanism 140 extends outward from the enclosure 110 along with the forklift 122. When it reaches below the object being transported, the lifting mechanism 140 performs a lifting action to lift the object. Since the lifting mechanism 140 is located below the forklift 122, it can simultaneously support the object being transported when the forklift 122 retracts, allowing for the transport of heavier objects.

[0051] It is quite similar, because a lifting mechanism 140 is provided below the fork-taking part 122. Therefore, when the fork-taking part 122 extends outward, it needs more space in the vertical direction with the enclosure part 110. Therefore, a notch is provided in the enclosure part 110 at the position corresponding to the fork-taking part 122. The notch is used to avoid the extension of the fork-taking part 122.

[0052] When the forklift section 122 retracts, the notch can also be used to retract the lifting mechanism 140. As is conceivable, since the lifting structure is a commonly used technical means, the specific structure of the lifting mechanism 140 will not be described in this application.

[0053] After the forklift mechanism 120 in this application has retrieved the object to be transported and returned it to the enclosure 110, the object can continue to be transported while being supported by the forklift mechanism 120. However, if the weight of the object is borne solely by the forklift mechanism 120, it is prone to damage during prolonged use. Therefore, a support portion 130 is further provided above the enclosure 110. When the forklift mechanism 120 is lowered to its lowest position, the forklift mechanism 120 is not higher than the support portion 130. When the forklift mechanism 120 is raised to its highest position, the forklift mechanism 120 is higher than the support portion 130. When the forklift portion 122 is retracted, the weight of the object to be transported can be supported by the support portion 130, or it can be shared by the support portion 130 and the forklift mechanism 120, thereby reducing the weight borne by the forklift mechanism 120.

[0054] In this application, the fork-taking mechanism 120 includes two forks, which are disposed on both sides of the carrying part 130. Each fork includes a fixing part 121 and a fork-taking part 122. The fork-taking part 122 is configured to extend to the outside of the enclosure part 110. The relative position of the fixing part 121 and the carrying part 130 remains unchanged.

[0055] See Figure 7 In one possible embodiment, the charging assembly 520 includes multiple inductive charging groups, which are spaced apart on the first lane and / or the second lane. Since the transport device 100 needs to obtain continuous function during travel, in order to ensure that the inductive charging groups are always in an inductive charging state with the transport device 100, the interval between each inductive charging group cannot exceed the width of the transport device 100 in its travel direction.

[0056] In a possible embodiment, the inductive charging group includes multiple coils connected in series. The coils are surrounded by a housing to protect them. The housing is directly installed on the roadway. Any two inductive charging groups spaced apart are electrically connected by wires to ensure that each inductive charging group can work normally.

[0057] The inductive charging assembly and the charging receiver 510 work together to receive power. When receiving power, the charging assembly 520 and the charging receiver 510 can be in contact or in a non-contact state. In the non-contact state, in order to ensure that the power receiving is carried out normally, the charging assembly 520 and the charging receiver 510 must maintain at least a minimum inductive distance.

[0058] This application may also include an energy storage device, which is mounted on the conveying device 100. The charging receiver 510 and the charging component 520 cooperate to receive power and charge the energy storage device, which then supplies power to the conveying device 100. Therefore, the conveying device 100 does not need to return to the charging station for recharging, thus improving the overall working efficiency of the conveying device 100.

[0059] The transport device 100 spends most of its time traveling along the first aisle (i.e., the main aisle) to pick up, place, and transport goods. Its built-in energy storage device only powers its movement outside the main aisle. Therefore, compared to existing technologies, it can incorporate a significantly smaller energy storage device, resulting in a smaller size and weight. Even with the additional charging receiver 510, it still saves space and reduces the overall weight of the transport device 100.

[0060] Preferably, the charging component 520 can be directly connected to the mains power supply within the warehouse area. Since mains power is high-voltage AC, although the charging component 520 can directly supply power in the form of high-voltage DC, and the charging receiver 510 performs AC-DC conversion after drawing power, because the automated warehouse requires personnel to enter for maintenance, to ensure environmental safety, in the preferred case, the charging component 520 provides a converted DC power supply with a voltage within a safe range.

[0061] Preferably, the charging receiver 510, in conjunction with the charging component 520, can directly supply power to the conveying device 100. This arrangement can reduce electrical losses during storage and discharge, and reduce heat dissipation.

[0062] In one possible embodiment, the charging receiver 510 and the charging component 520 can be a brush head and a sliding contact line, with the brush head in contact with the sliding contact line for receiving power. In another possible embodiment, the charging receiver 510 and the charging component 520 can be an inductive receiver and an inductive charging component, such as an electromagnetic coil, for inductive power receiving. For inductive power receiving, the charging receiver 510 and the charging component 520 may or may not be in contact.

[0063] See Figure 8This application provides a warehousing system, which includes a power supply system, a warehouse, and a handling device 100. The warehouse includes multiple intersecting vertically arranged aisles 200 and storage locations 300 disposed between the aisles 200. A charging component 520 in the power supply system is disposed on the aisle 200 and supplies power to the handling device 100 through inductive charging when it travels along the aisle 200. There are no aisles 200 below the storage locations 300. The handling device 100 travels on the aisle 200 and uses a forklift mechanism 120 to pick up the objects placed in the storage locations 300.

[0064] Since storage locations 300 are generally located on both sides of the sub-track, the handling device 100 needs to travel along the sub-track to the corresponding location of the storage location 300. In the prior art, where an aisle 200 is provided below the storage location 300, the handling device 100 needs to change its direction of travel from the sub-track to the storage location 300. Therefore, the handling device 100 needs to stop when it reaches the storage location 300, and then change its direction of travel before continuing. One travel process involves multiple processes such as acceleration, deceleration, stopping, and determining the stopping position of the handling device 100. Even if it can be achieved through program control, it still takes time to complete. However, in this application, because the handling device 100 is equipped with a forklift mechanism 120, the aisle 200 is not provided below the storage location 300 in the warehousing system. The handling is directly carried out through the forklift mechanism 120, reducing one travel action (traveling from the sub-track to the storage location), which can reduce the handling time, improve handling efficiency, and also reduce the construction cost of the automated warehouse.

[0065] Furthermore, the storage location 300 is set at a height no lower than the lowest descending position of the forklift mechanism 120, so as to ensure that the forklift mechanism 120 can extend below the storage location 300 to forklift and transport objects.

[0066] In this application, by setting up continuous enclosures around the vehicle and installing a forklift mechanism that can extend outside the vehicle body above the enclosures, the handling equipment can move goods without having to travel under them. At the same time, a charging receiver is installed so that the handling device can receive power through the charging components and the charging receiver while traveling in the aisle, so as to power the four-way shuttle. This ensures that the handling device can work continuously without having to return to the charging station to recharge, thus improving the overall working efficiency of the handling device.

[0067] In order to make the purpose, technical solution and advantages of the embodiments of this application clearer, the technical solution of this application has been clearly and completely described in conjunction with the specific embodiments and accompanying drawings.

[0068] It should be understood that the steps shown above in conjunction with specific embodiments are illustrative. Those skilled in the art can add or delete corresponding steps, adjust the execution order of one or more steps, or replace one or more steps with similar steps.

It will be apparent to those skilled in the art that the disclosed subject matter may be implemented in other specific forms without departing from its spirit and essential characteristics.
