Description

Technical Field

[0001] This invention relates to the field of auxiliary component technology, and more specifically, to an auxiliary component for logistics palletizing. Background Technology

[0002] With the rapid development of the modern logistics industry, warehouse spaces are typically equipped with multiple sets of storage racks. Various types of goods are neatly placed on the shelves on each shelf using pallets, thereby achieving classified storage and centralized management of goods. In conventional warehousing operations, the stacking of goods is carried out layer by layer from the bottom shelf to the top, while the picking operation is carried out layer by layer from the top shelf to the bottom. At present, all picking and placing operations of goods on the shelves are mechanized by forklift equipment. Forklifts use the lifting and lateral movement of their forks to achieve the storage, retrieval and transfer of goods.

[0003] However, there are significant limitations and safety hazards in the process of using forklifts to store and retrieve goods from high-bay racks, affecting the accuracy and safety of warehousing operations. Firstly, when storing goods on high-bay rack shelves, the goods are placed on the forks via pallets. As the forks lift the pallets, the goods obstruct the operator's view, making it difficult for the operator to accurately judge the real-time lifting and lowering positions of the forks and shelves. If the lifting and lowering position of the goods on the forks deviates, the sidewalls of the goods are very likely to collide hard with the rack supports and shelves during the subsequent horizontal transfer of the goods into the rack. This can not only cause damage to the goods and deformation of the rack structure, but also pose a significant safety hazard on site. Secondly, when retrieving goods from high-level shelves, the high working height causes goods at the top of the shelf and the bottom pallets to be placed close to the surface of the shelf, creating blind spots for the operator. This makes it impossible to accurately observe the position of the insertion holes at the bottom of the pallets and to quickly and accurately insert the forks into the pallet holes. This not only significantly increases the difficulty of high-level retrieval operations and reduces the efficiency of warehouse retrieval operations, but also makes it easy for misalignment to cause collisions and damage to the forks, pallets, and goods. Summary of the Invention

[0004] This invention provides an auxiliary component for logistics palletizing, solving the technical problems of damage and reduced efficiency in related technologies.

[0005] This invention provides an auxiliary component for logistics palletizing, comprising: The shelving unit has several storage spaces arranged in layers along the vertical direction, and the shelving unit is equipped with slide rails along the vertical direction. The trigger unit is slidably mounted on the slide rail and can move up and down along the slide rail; A cargo pallet is used to carry goods and can be lifted and moved by forks. The cargo pallet is equipped with a linkage part for cooperating with a trigger unit to drive the trigger unit to lift and lower. The control unit, located on the shelf, is used to control the indicator lights to turn on or off based on the lifting position of the trigger unit.

[0006] As a further optimization of the present invention, the triggering unit includes: The slider is slidably positioned within the slide rail. The transmission rod is mounted on the slider via a connecting member; The abutment block is fixedly mounted on the slider and is used to trigger the control unit when the trigger unit rises or falls to a preset position.

[0007] As a further optimization of the present invention, the linkage part is a horizontal support plate fixedly installed at the bottom of the cargo pallet. One end of the horizontal support plate extends outward to the outside of the cargo pallet and is used to abut against the transmission rod during the lifting or lateral movement of the cargo pallet to drive the trigger unit to lift and move synchronously.

[0008] As a further optimization of the present invention, the cargo pallet also includes a support plate, which is disposed at the bottom of the cargo pallet and located below the transverse support plate, and is used to support the transmission rod after the transverse support plate is disengaged from the transmission rod, so as to limit the falling of the trigger unit.

[0009] As a further optimization of the present invention, the support plate is horizontally slidably connected to the support leg of the cargo pallet, and the support plate is vertically slidably connected to the support leg through a connecting plate. The connecting plate has an inclined sliding groove, and the support plate has a columnar slider that slides in conjunction with the inclined sliding groove. When the connecting plate slides vertically relative to the support leg, the support plate extends and retracts horizontally under the guidance of the inclined sliding groove.

[0010] As a further optimization of the present invention, the lower end of the connecting plate extends downward to the bottom surface of the support leg. When the cargo pallet is placed downward onto the surface of the shelf, the lower end of the connecting plate first contacts the shelf and is pushed upward relative to it, thereby causing the support plate to retract horizontally to disengage from the transmission rod.

[0011] As a further optimization of the present invention, the control unit includes: The mounting plate is fixedly mounted on the slide rail; A sliding rod is slidably mounted on the assembly plate, with one end facing the abutment block; The switch is fixedly mounted on the mounting plate and located at the other end of the slide rod; When the abutment block rises and falls to the predetermined position with the trigger unit, the abutment block pushes the slide bar to slide and trigger the switch, thereby controlling the indicator light to light up or turn off.

[0012] As a further optimization of the present invention, an elastic element is provided at the sliding engagement point between the slide rod and the mounting plate to provide a reset force for the slide rod to disengage from the switch.

[0013] As a further optimization of the present invention, it also includes a fork with a notch. When the fork extends into the bottom of the cargo pallet, the transmission rod of the triggering unit can fall into the notch, so that the triggering unit disengages from the fork and resets.

[0014] As a further optimization of the present invention, the shelf includes multiple vertical supports and multiple horizontal shelves, with adjacent upper and lower shelves forming a storage space, and a slide rail fixed to one of the vertical supports and extending in the vertical direction.

[0015] The beneficial effects of this invention are as follows: 1. The auxiliary component for logistics palletizing described in this invention, through the combination of a sliding trigger unit, a control unit, and an indicator light structure, allows for the trigger unit to synchronously raise and lower the pallet along with the goods during high-level racking operations, triggering a light signal. The indicator light illuminates first and then turns off, providing visual feedback on the lifting height of the pallet relative to the target storage space. This solves the technical defects of goods obstructing the operator's view and hindering accurate judgment of the lifting position during high-level racking operations. It also reduces the problem of hard collisions between goods, pallets, rack supports, and shelves caused by height misalignment, lowering the probability of goods damage and rack structure deformation, and reducing safety hazards in high-level racking operations.

[0016] 2. The auxiliary component for logistics palletizing described in this invention, through the cooperation of a fork notch avoidance structure, a triggering unit, a control unit, and a light alignment prompting structure, accurately indicates the horizontal alignment status of the forks during high-level picking operations via indicator light signals. This eliminates the need for operators to visually observe the pallet insertion hole positions in high-level blind spots, thus solving the problems of blind spots, difficulty in insertion hole alignment, high operational difficulty, and low work efficiency in high-level rack picking. It also avoids damage to pallets and goods caused by alignment deviations, reducing the difficulty of high-level picking operations and improving the accuracy and overall efficiency of high-level warehouse picking operations.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] like Figure 1 As shown, an auxiliary component for logistics palletizing includes a shelf 1, a triggering unit 2, a cargo pallet 3, and a control unit 4; like Figure 1 As shown, the overall assembly structure of the shelf 1 is composed of multiple vertical supports 11 and multiple horizontal shelves 13 spliced ​​together. The adjacent upper and lower shelves 13 enclose a storage space 10 for storing and stacking goods. The shelf 1 has several independent storage spaces 10 arranged in layers along its vertical height. A slide rail 12 is installed on the front side of the shelf 1 facing the operator for placing goods. The slide rail 12 is fixedly connected to a support 11 on the front side. The slide rail 12 extends vertically and its total length is greater than the sum of the vertical heights of all storage spaces 10 on the shelf 1. The trigger unit 2 is slidably connected to the slide rail 12 by a sliding pair. The trigger unit 2 can slide up and down along the slide rail 12 and can slide to the front operating position of any storage space 10. Initially, the trigger unit 2 is located at the lower end of the slide rail 12. Each independent storage space 10 is equipped with an indicator light 14 and an independent control unit 4. The control unit 4 configured inside the same storage space 10 can independently control the on and off states of the corresponding indicator light 14. The control of the indicator light 14 in each storage space 10 is independent and does not interfere with each other. like Figure 2 As shown, the pallet 3 serves as the supporting base of the rack 1. Workers can use the forks 5 of the forklift to lift and transfer the pallet 3, which makes it easy to stack various goods in an orderly manner in the storage space 10 of each layer of the rack 1. The cargo pallet 3 is mainly composed of a pallet surface 31 and three support legs 32 to form an overall load-bearing structure. The three support legs 32 are arranged and fixed at equal intervals along the bottom surface of the pallet surface 31. Any two adjacent support legs 32 form an insertion hole that allows forklift forks 5 to be inserted. like Figure 3 As shown, a transverse support plate 33 is fixedly installed on the middle position of the side wall of a single support leg 32 facing the inside of the socket. One end of the transverse support plate 33 extends outward to the outside of the support leg 32, and the end face of the other end is flush with the end face of the side wall of the support leg 32. A support plate 34 is assembled on the end of the support leg 32 that is flush with the transverse support plate 33. The support plate 34 and the support leg 32 form a horizontal sliding structure, and the height of the support plate 34 on the support leg 32 is less than the height of the transverse support plate 33 on the support leg 32. like Figure 4As shown, a connecting plate 341 is provided on the side of the support plate 34 facing the transverse support plate 33. The connecting plate 341 is vertically inserted into the transverse support plate 33 and forms a vertical sliding connection with it. The side wall of the connecting plate 341 is provided with an inclined groove structure. The columnar slider integrally formed by the support plate 34 is slidably disposed in the inclined groove. In the initial state, the columnar slider stays at the uppermost position of the inclined groove. A reset spring rod 342 (composed of a spring inside the telescopic tube) is assembled between the connecting plate 341 and the support leg 32. The lower end of the connecting plate 341 extends downward out of the bottom surface of the support leg 32. When the cargo pallet 3 is lowered onto the surface of the shelf 13, the lower end of the connecting plate 341 will first contact the top surface of the shelf 13. Under the upward pushing force of the shelf 13, the connecting plate 341 slides vertically upward relative to the support leg 32. During the sliding process, the inclined groove and the inclined surface of the columnar slider are used for transmission to synchronously drive the support plate 34 to complete the telescopic sliding action in the horizontal direction. like Figure 5 As shown, the triggering unit 2 is mainly composed of a slider 21, a horizontal connecting rod 22, a vertical connecting rod 23, a transmission rod 24, a stop block 26, and a buffer spring rod 27 to form a complete linkage structure. The slider 21 is slidably embedded in the slide rail 12 and can make vertical reciprocating sliding motion along the slide rail 12. The horizontal connecting rod 22 is set as an L-shaped structure. One end of the horizontal connecting rod 22 is fixedly connected to one side wall of the slider 21. The end of the horizontal connecting rod 22 away from the slider 21 is fixedly connected to the bottom end of the vertical connecting rod 23. The upper end of the vertical connecting rod 23 is connected to the middle section of the transmission rod 24. The side wall of the slider 21 opposite to the horizontal connecting rod 22 is fixed with a stop block 26 in the vertical direction. The upper and lower surfaces of the stop block 26 are both processed into inclined slopes facing opposite directions, so that the stop block 26 forms a trapezoidal block structure. The stop block 26 is located outside the slide rail 12. The bottom end of the slider 21 is equipped with a buffer spring 27 (composed of a spring inside the telescopic tube). When the trigger unit 2 slides down the slide rail 12 and collides with the ground, the buffer spring 27 can reduce the impact force and play a buffering protective role. Regarding the L-shaped design of the transverse connecting rod 22, the L-shaped transverse connecting rod 22 can reserve clearance space during the entire process of the trigger unit 2 sliding up and down the slide rail 12 to avoid interference and collision with the support plate 34 during the sliding process. like Figure 6As shown, the control unit 4 consists of an assembly plate 41, a slide rod 42, and a switch 43. The assembly plate 41 is fixedly installed on the side wall surface of the slide rail 12. The slide rod 42 is slidably engaged with the assembly plate 41. An elastic element 44 (spring) is installed at the sliding engagement position of the slide rod 42 and the assembly plate 41. The elastic element 44 provides the slide rod 42 with an automatic reset force. The end of the slide rod 42 facing the slide rail 12 is machined with a rounded corner structure, and the other end of the slide rod 42 faces the switch 43 fixed on the assembly plate 41. When the trigger unit 2 slides to the front of the corresponding storage space 10, the slide rod 42 is pushed by an external force and slides, coming into contact with the switch 43. After receiving the trigger signal, the switch 43 controls the indicator light 14 of the same storage space 10 to turn on and illuminate. When the external force is removed, the elastic element 44 drives the slide rod 42 to slide in the opposite direction and separate from the switch 43. At this time, the switch 43 disconnects the control circuit, and the indicator light 14 of the corresponding storage space 10 turns off. like Figure 7 As shown, a notch 51 is made at the end of the fork 5 facing away from the direction of travel of the forklift; like Figure 8 As shown, guide lines are marked on the ground in front of the workstation of the shelf 1. These guide lines extend along the direction of loading and unloading operations. Operators can use the guide lines to quickly calibrate the parking position of the forklift, ensuring that the forks 5 or the pallet 3 can be connected with the transmission rod 24 after they are moved into place.

[0021] Working principle of this invention: When placing goods on shelf 1, such as Figure 9 As shown in A, the forks 5 first lift the pallet 3 and the goods on the pallet 3 and move them to the front of the shelf 1. One end of the transverse support plate 33 extending out of the support leg 32 is below the transmission rod 24. Then the forks 5 drive the pallet 3 to rise, so that the extended end of the transverse support plate 33 fits against the transmission rod 24. like Figure 9 As shown in Figure B, the fork 5 lifts the cargo pallet 3 and simultaneously drives the trigger unit 2 to move upward. When the cargo pallet 3 is raised to the height of the corresponding storage space 10, the abutment block 26 pushes the slide bar 42, the slide bar 42 touches the switch 43, and the corresponding indicator light 14 lights up. like Figure 9 As shown in C, the fork 5 continues to lift the cargo pallet 3, the abutment block 26 disengages from the slide bar 42, the slide bar 42 resets and releases the switch 43, and the indicator light 14 goes out; after the operator observes the prompt signal that the indicator light 14 first lights up and then goes out, he stops lifting the cargo pallet 3 and completes the height positioning of the cargo pallet 3. At this time, the cargo pallet 3 is higher than the storage plate 13 at the bottom of the storage space 10. like Figure 10 China A and Figure 11As shown, the forks 5 lift the pallet 3 and move it horizontally into the storage space 10. During the horizontal movement of the pallet 3, the transverse support plate 33 slides along the bottom surface of the transmission rod 24 until the two are completely separated. The transverse support plate 33 loses its support for the trigger unit 2, and the trigger unit 2 slides downward by its own weight. The transmission rod 24 is connected to the support plate 34 to achieve a limit. The lower end of the abutment block 26 pushes the slide rod 42 again to trigger the switch 43. The indicator light 14 lights up, and the operator stops the horizontal feeding of the forks 5. At this time, the pallet 3 is facing the storage plate 13 at the bottom of the storage space 10. like Figure 4 and Figure 10 As shown in Figure B, the forklift 5 drives the pallet 3 to fall downwards. As the pallet 3 falls toward the shelf 13, the bottom of the connecting plate 341 protrudes downwards and first contacts the top surface of the shelf 13. Under the obstruction of the shelf 13, the connecting plate 341 slides vertically upwards relative to the support leg 32. Through the inclined slide groove and the inclined surface transmission of the columnar slider, the support plate 34 slides horizontally and gradually separates from the transmission rod 24. After the shelf 13 fully supports the pallet 3, the support plate 34 and the transmission rod 24 are completely separated. The trigger unit 2 slides down to the initial position by its own weight, the abutment block 26 separates from the slide rod 42, and the indicator light 14 goes out. This signal prompts the operator that the pallet is in place, and then the forklift can be operated to remove the forklift 5.

[0022] If you need to place goods again, repeat the above steps.

[0023] When retrieving goods from shelf 1, such as Figure 12 As shown in Figure A, the fork 5 is moved below the transmission rod 24, and then the trigger unit 2 is raised by the fork 5; when the trigger unit 2 slides to the position of the storage space 10 corresponding to the goods to be picked up, the abutment block 26 pushes the slide rod 42, the slide rod 42 contacts the switch 43, the corresponding indicator light 14 lights up, and then the lifting of the fork 5 stops. At this time, the fork 5 is aligned with the insertion hole of the goods pallet 3; Figure 12 As shown in Figure B, the fork 5 extends horizontally into the insertion hole of the cargo pallet 3. During the translation process, the fork 5 slides along the bottom surface of the transmission rod 24 until the transmission rod 24 reaches the notch 51 opened by the fork 5. At this point, the trigger unit 2 loses support and slides down to reset under its own weight. The abutment block 26 separates from the slide rod 42, and the indicator light 14 goes out. This light signal indicates to the operator that the fork 5 has been fed horizontally into place. Then, the fork 5 is raised to lift the cargo pallet 3 and the goods on it. The cargo pallet 3 is then moved horizontally out in the opposite direction, thus completing the entire picking operation.
