[0036] The following are specific embodiments to illustrate the implementation manners of the present invention regarding "a forklift, a cargo handling device and its picking module". Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. Additionally, the drawings of the present invention are only simple schematic illustrations and are not drawn according to actual dimensions, hereby declared in advance. The following implementation manners will further detail the relevant technical content of the present invention, but the disclosed content is not intended to limit the protection scope of the present invention.

[0037] It should be understood that although terms such as "first", "second", "third", etc. may be used herein to describe various components or features, these components or features should not be limited by these terms. These terms are mainly used to distinguish one component from another, or one feature from another. In addition, the term "or" used herein may, depending on the actual situation, include any one or a combination of more of the associated listed items.

[0038] Please refer to Figures 1 to 10 as shown, which is an embodiment of the present utility model. As Figures 1 to 3 shown, this embodiment discloses a carrier 1000, which can be applied to an automated operating system. The carrier 1000 in this embodiment includes a traveling device 200 capable of moving on the ground, a mast device 300 installed on the traveling device 200, and a cargo handling device 100 installed on the mast device 300, but the present utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the mast device 300 of the carrier 1000 can be omitted or replaced by other components according to actual needs; or, the cargo handling device 100 can also be applied alone (such as: vending) or used in combination with other devices.

[0039] In this embodiment, the cargo handling device 100 includes a base 1, two first telescopic arms 2 installed on the base 1, two second telescopic arms 3 respectively corresponding to the two first telescopic arms 2, two lever mechanisms 4, and a driving mechanism 5 arranged on the base 1. Each of the lever mechanisms 4 is installed between one of the first telescopic arms 2 and the corresponding second telescopic arm 3 to jointly define a picking module 10.

[0040] That is to say, the cargo handling device 100 in this embodiment is described by adopting two of the lever mechanisms 4, but the present utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the cargo handling device 100 can also be configured with only one of the lever mechanisms 4 according to actual needs, which is installed between one of the first telescopic arms 2 and the corresponding second telescopic arm 3 to jointly define one of the picking modules 10.

[0041] In this embodiment, the base 1 is installed on the mast device 300, and the base 1 includes a bottom plate 11 and two side plates 12 respectively vertically connected to both side edges of the bottom plate 11. Two of the first telescopic arms 2 are respectively installed on the inner edges of the two side plates 12, and a linear slide rail (not marked in the figure) can be used to connect between each of the first telescopic arms 2 and the corresponding second telescopic arm 3, and the two first telescopic arms 2 and the two second telescopic arms 3 can move synchronously through the driving mechanism 5.

[0042] It should be noted first that in this embodiment, the goods handling device 100 may optionally adopt a single driving mechanism 5 to synchronously drive the two picking modules 10 to run, so as to simplify the overall structure and control effect. Among them, the driving mechanism 5 is described as including a motor 51 and a linkage rod 52 connected to the motor 51, and the two picking modules 10 can run synchronously through the motor 51 and the linkage rod 52, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the goods handling device 100 may also be configured with two driving mechanisms 5 according to actual needs to respectively drive the two picking modules 10.

[0043] Furthermore, each first telescopic arm 2 can move outwards from a first initial position (such as: Figure 3 and Figure 4 shown) located in the base 1 along an operating direction D to a first extended position (such as: Figures 5 to 7 shown). Each second telescopic arm 3 can move outwards from a second initial position (such as: Figure 3 and Figure 4 shown) located in the base 1 along the operating direction D to a second extended position (such as: Figure 7 shown). Among them, each first telescopic arm 2 can reciprocate between the first initial position and the first extended position, and each second telescopic arm 3 can reciprocate between the second initial position and the second extended position, and a picking opening 32 is defined between the outer edges 31 of the two second telescopic arms 3 located at the second extended position.

[0044] In addition, since the two picking modules 10 in this embodiment adopt a substantially identical structure and are arranged in a mirror-symmetrical configuration with each other, for the convenience of understanding, the following content mainly introduces the structure and connection relationship of one of the picking modules 10, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the structures of the two picking modules 10 may also be slightly different or not in a mirror-symmetrical configuration; or, the picking module 10 may also be used alone (such as for vending) or in combination with other structures.

[0045] In this embodiment, as Figures 2 to 4As shown, the lever mechanism 4 is generally located between the first telescopic arm 2 and the second telescopic arm 3, and the lever mechanism 4 includes a front limiting portion 41 fixed to the first telescopic arm 2, a rear limiting portion 42 fixed to the second telescopic arm 3, a guiding seat 43, a transmission rod 44 passing through the rear limiting portion 42 and the guiding seat 43, an elastic member 45 disposed between the rear limiting portion 42 and the transmission rod 44, a lever 46 pivotally connected to the guiding seat 43, and a locking member 47 pivotally connected to the guiding seat 43 and adjacent to the lever 46. However, the present invention is not limited thereto.

[0046] It should be noted that the front limiting portion 41, the rear limiting portion 42, and the guiding seat 43 are independent components in this embodiment and are fixed to the corresponding first telescopic arm 2 and second telescopic arm 3. And the front limiting portion 41 is located between the guiding seat 43 and the rear limiting portion 42 along the running direction D (that is to say, the front limiting portion 41 and the rear limiting portion 42 are spaced apart from each other along the running direction D), and the guiding seat 43 may be adjacent to the goods pickup port 32. However, the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the front limiting portion 41 may be integrally formed on the first telescopic arm 2, and the rear limiting portion 42 and / or the guiding seat 43 may also be integrally formed on the second telescopic arm 3.

[0047] The transmission rod 44 is generally parallel to the running direction D, and the transmission rod 44 passes through the rear limiting portion 42, the front limiting portion 41, and the guiding seat 43 along the running direction D. Wherein, one end of the transmission rod 44 passes through the rear limiting portion 42, and the other end of the transmission rod 44 passes through the guiding seat 43. It should be additionally noted that the term "pass through" in this embodiment does not imply fixation, so any two components "passing through" each other can move relative to each other.

[0048] More specifically, the transmission rod 44 is formed with a protrusion 441 located between the front limiting portion 41 and the rear limiting portion 42 along the running direction D, and the protrusion 441 is annular in this embodiment. Furthermore, the transmission rod 44 has a driving end portion 442 away from the protrusion 441 (and the rear limiting portion 42), and the driving end portion 442 protrudes from the second telescopic arm 3 (or the goods pickup port 32).

[0049] The elastic member 45 (such as a spring) is disposed between the protrusion 441 and the rear limiting portion 42. And in this embodiment, the elastic member 45 is sleeved on the transmission rod 44, and two ends of the elastic member 45 respectively abut against or are fixed to the protrusion 441 and the rear limiting portion 42. However, the present utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the elastic member 45 may also adopt components other than springs according to actual requirements.

[0050] The lever 46 has a free end portion 461, a pivoting portion 462 pivotally connected to the guiding seat 43, and a linkage segment 463 located between the free end portion 461 and the pivoting portion 462. Wherein, the linkage segment 463 of the lever 46 is connected to the driving end portion 442 of the transmission rod 44. And in this embodiment, the linkage segment 463 is a long slot, and the driving end portion 442 is movably connected to the long slot. However, the present utility model is not limited thereto.

[0051] Furthermore, the position of the free end portion 461 corresponds to the goods taking opening 32. For example, as Figure 3 shown, when the first telescopic arm 2 is in the first initial position and the second telescopic arm 3 is in the second initial position, the free end portion 461 does not shield the goods taking opening 32; however, as Figure 7 shown, when the first telescopic arm 2 is in the first extended position and the second telescopic arm 3 moves along the running direction D to the second extended position, the free end portion 461 shields at least a part of the goods taking opening 32.

[0052] As Figures 2 to 4 shown, the lever 46 forms a notch 464 at the pivoting portion 462, and the locking member 47 is a ratchet pawl corresponding to the notch 464 in position. Further, the locking member 47 has a rotating portion 471 pivotally connected to the guiding seat 43, a locking segment 472 located on one side of the rotating portion 471, and an unlocking segment 473 located on the other side of the rotating portion 471. Wherein, the rotating portion 471 of the locking member 47 is located inside the pivoting portion 462 of the lever 46 (i.e., on the side close to the first telescopic arm 2), and the locking segment 472 is generally located on the action path of the notch 464 when the pivoting portion 462 rotates.

[0053] In addition, a starting portion 22 is formed at the end edge 21 of the first telescopic arm 2, and the starting portion 22 is columnar and is arranged along the running direction D with the unlocking segment 473. In other words, as Figure 3As shown, when the first telescopic arm 2 is in the first initial position and the second telescopic arm 3 is in the second initial position, the starting portion 22 abuts against the unlocking section 473 of the locking member 47.

[0054] The above is the structural description of each component of the picking module 10 in this embodiment. Next, the interlocking relationship of each component of the picking module 10 will be introduced. Among them, when the first telescopic arm 2 is in the first extended position and the second telescopic arm 3 moves to an intermediate position adjacent to the second extended position (e.g., Figure 5 as shown, not yet reaching the second extended position), the transmission rod 44 abuts against the front limiting portion 41 through the protrusion 441 and remains stationary, and the second telescopic arm 3 can continue to move towards the second extended position, so that the linkage section 463 is driven by the guiding seat 43 to rotate relative to the driving end portion 442 (e.g., Figure 6 and Figure 7 as shown), thereby enabling the free end portion 461 to block at least part of the picking opening 32 (along the running direction D) to facilitate the subsequent picking operation.

[0055] Thus, in this embodiment, the picking module 10 can, through the structural design of the lever mechanism 4 in combination with the first telescopic arm 2 and the second telescopic arm 3, enable the lever 46 for shielding the picking opening 32 to be interlocked with the extended movement of the first telescopic arm 2 and the second telescopic arm 3, and thus there is no need to separately adopt an independently operating drive motor, effectively simplifying the structure and control mode of the handling vehicle 1000 and reducing its production and maintenance costs.

[0056] Furthermore, as Figure 7 shown, when the first telescopic arm 2 is in the first extended position and the second telescopic arm 3 moves to the second extended position, the elastic member 45 is deformed by the compression of the front limiting portion 41 and the rear limiting portion 42 and stores a resilience, and the lever 46 is locked to the locking member 47 (e.g., the lever 46 is locked to the locking section 472; or rather, the locking member 47 is embedded in the notch 464), so that during the process of the first telescopic arm 2 moving towards the first initial position and the second telescopic arm 3 moving towards the second initial position (e.g., Figure 8 as shown), the free end portion 461 remains blocking at least part of the picking opening 32.

[0057] In other words, as Figure 5 and Figure 6As shown, before the second telescopic arm 3 has moved to the second extended position (e.g., located at the intermediate position), the locking member 47 falls outside the notch 464, thus enabling the lever 46 to rotate.

[0058] Furthermore, the following describes the relevant operation of the picking module 10 retracting into the base 1 after the picking module 10 has picked up the goods. As Figure 9 and Figure 10 shown, when the first telescopic arm 2 moves to the first initial position and the second telescopic arm 3 moves to the second initial position, the locking member 47 is pushed against by the starting portion 22 and unlocks and separates from the lever 46 (e.g., the unlocking section 473 is pushed against by the starting portion 22 and rotates, so that the locking section 472 unlocks and separates from the lever 46), and releases the resilience stored in the elastic member 45, so that the free end 461 can leave the picking opening 32.

[0059] It should be additionally noted that in this embodiment, the lever 46 realizes its positioning requirement by being matched with the locking member 47 and in a fitting manner, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the lever 46 can also adopt ways other than fitting (such as the magnetic attraction way of a magnet, the meshing way of a gear, or the limiting way of a connecting rod) to realize its positioning requirement.

[0060] [Technical effects of the embodiments of the present invention]

[0061] In summary, for the forklift truck, the goods handling device and its picking module disclosed in the embodiments of the present invention, through the structural design of the lever mechanism being matched with the first telescopic arm and the second telescopic arm, the lever used to shield the picking opening can be linked to the extended movement of the first telescopic arm and the second telescopic arm, and thus there is no need to separately adopt a driving motor that operates independently, effectively simplifying the structures and control methods of the forklift truck and the goods handling device and significantly reducing their production and maintenance costs.

[0062] The content disclosed above is only an optional and feasible embodiment of the present invention, and does not limit the patent scope of the present invention.
