Although some factories have built automated stereoscopic warehouses, the bin stacker generally adopts the plate fork method; if a clamping fork stacker is used, it can only handle bins with a height ≥ 150 mm. If the installation site has height restrictions and the ground bearing capacity is not high, and the customer wants to obtain more bin positions and improve the space storage density, there is no suitable method to achieve this.

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0062] Refer to Figure 1-27 , a super-light stacking machine system for an automatic folding box, including a conveyor 1, an automatic folding box machine 2 located in the inlet direction of the conveyor 1, and a stacking machine 3 located on the side of the outlet of the upper shelf of the conveyor 1.

[0063] During warehousing, the automatic folding box machine 2 stacks a plurality of bins 4 together, and the stacking machine 3 pushes and moves the stacked bins 4 to the shelf for warehousing; during outbound, the stacking machine 3 pushes and moves the stacked bins 4 placed on the shelf to the conveyor 1, and the automatic folding box machine 2 disassembles the stacked bins 4 and conveys them out of the warehouse in sequence.

[0064] As Figure 1 , 3 shown, the system adopts a modular design; the conveyor 1 conveys the bin 4 forward for warehousing; when the bin 4 passes through the automatic folding box machine 2, the automatic folding box machine 2 stacks a plurality of bins 4 together; as Figure 1 , 4 shown, two bins 4 are stacked; then, the stacked bins 4 continue to be conveyed forward by the conveyor 1; when reaching the working position of the stacking machine 3, the stacking machine 3 pushes and moves the bin 4 to the shelf for warehousing.

[0065] As Figure 2 shown, the telescopic clamping fork 9 of the stacking machine 3 pulls the bin 4 into it; then, after transporting it to the designated position, the bin 4 is sent into the stereoscopic warehouse.

[0066] It should be noted that:

[0067] The conveyor 1 is a roller conveyor; as Figure 4 shown, there is a gap between adjacent rollers.

[0068] The bin 4 is a turnover box provided with an upper edge; as Figure 24As shown, for a relatively conventional plastic turnover box, the lid can be optionally set; its edge cooperates with the pawl 64 of the automatic folding box machine 2 to lift the whole box up.

[0069] It can be understood that Figure 24 It is only a schematic diagram of the bin 4; turnover box structures with upper edges in other forms can all be used.

[0070] It should be noted that:

[0071] In this system, the height of the bin 4 adopted can be less than 150 mm;

[0072] Thus, it can be used for the handling and warehousing of low bins; by stacking two or more bins to form a multiple height, the conventional telescopic clamping fork 9 can be used for handling.

[0073] In some embodiments, the automatic folding box machine 2 includes: a bracket 20, a blocking component 5 located below the conveyor 1, and a box-lifting component 6 located above the conveyor 1.

[0074] As Figure 4-10 shown, the bracket 20 is a square tube frame structure and is provided with components such as a panel, a control circuit, and a gas circuit; correspondingly, the blocking component 5 and the box-lifting component 6 are installed on the bracket 20.

[0075] In some embodiments, adjustment support and fixing parts are provided below the conveyor 1 and the automatic folding box machine 2 to level and support the main body, ensuring high reliability, balance, and accuracy.

[0076] Specifically, as Figure 4-7 shown; the adjustment support part includes: a vertically arranged U-shaped part that cooperates with the legs of the conveyor 1 and the automatic folding box machine 2, and a horizontal mounting plate integrally provided at the lower end of the U-shaped part.

[0077] The three sides of the leg are clamped by the U-shaped part; at the same time, no less than two vertical slots are opened on the wide plate of the U-shaped part; adjustment and fixing are carried out in cooperation with bolts.

[0078] In some embodiments, the blocking component 5 includes: a lifting baffle 51 arranged at the outlet end of the automatic folding box machine 2; the lifting baffle 51 is located between the two rollers of the conveyor 1.

[0079] Thus, when the bin 4 needs to pass through, the lifting baffle 51 hides downward, and its top end is lower than the roller; when the bin 4 needs to be blocked, it is lifted and raised to form a blocking surface.

[0080] Specifically, at the lower position of the conveyor 1, there is provided: a first mounting plate 21 fixed at both ends on the bracket 20; a vertically arranged cylinder is installed on the first mounting plate 21, and the lifting baffle 51 is assembled at the telescopic end of the cylinder.

[0081] As Figure 6 shown; after the lifting baffle 51 is lifted, it blocks the lower bin 4.

[0082] Furthermore, U-shaped guide rails 52 for guiding the lifting baffle 51 are provided on both sides above the first mounting plate 21; as Figure 9 、 11 、12 shown, the U-shaped guide rails 52 provided on both sides catch the lifting baffle 51 to form a limit in the front and back conveying directions, improve the stability of the lifting baffle 51, and reduce the load on the cylinder.

[0083] Furthermore, on the first mounting plate 21, there is also provided: a guide rod connected to the lower end of the lifting baffle 51 and sliding through the first mounting plate 21; as Figure 11 、 12 shown, auxiliary guide rods are provided on both sides to better control the stability.

[0084] Furthermore, a rubber strip is assembled at the inner end of the first mounting plate 21; while thickening the mounting plate structure, it also forms a flexible contact to reduce damage to the bin 4.

[0085] Preferably, as Figure 12 、 13 shown; the cylinder is not directly assembled with the lifting baffle 51, but a horizontal plate is fixedly connected to the rear end of the lifting baffle 51, and the horizontal plate is assembled at the top of the cylinder and the guide rod; thus, it is not necessary to set the lower end of the lifting baffle 51 very wide, and the cooperation between the lifting baffle 51 and the horizontal plate is more reasonable and reliable.

[0086] In some embodiments, the blocking assembly 5 further includes: a three-fold crank arm 53 provided at the inlet end of the automatic folding box machine 2.

[0087] As Figure 5 、 6 shown, the first mounting plate 21 is located at the outlet end of the warehouse, and the three-fold crank arm 53 is located at the inlet end of the warehouse; during box stacking, it is limited from two directions; and, it is set as two blocking members to cooperate with the blocking effects required for different situations during warehousing and outwarehousing.

[0088] In some embodiments, a second mounting plate 22 with both ends fixed to the bracket 20 is provided at the lower position of the conveyor 1; a second support 24 extending towards the inlet side is provided on the front end face of the second mounting plate 22, and the middle part of the three-fold crank arm 53 is hinged to the second support 24 on the second mounting plate 22; a first support 23 is provided at the lower end of the second mounting plate 22, and a cylinder is rotatably clamped and installed inside the first support 23, and the telescopic end of the cylinder is hinged to the three-fold crank arm 53.

[0089] As Figure 14 、15 As shown; driven by a cylinder, the triple-folded crank arm 53 forms a blocking state of lifting upward or a releasing state of hiding downward; it can be understood that the triple-folded crank arm 53 rises and falls between the two rollers of the conveyor 1 without interference.

[0090] It should be noted that the triple-folded crank arm 53 is composed of two symmetrically arranged arm plates, and a connecting rod is arranged between the two arm plates; moreover, a flexible sleeve is sleeved outside the connecting rod at the top end of the triple-folded crank arm 53; preferably, as Figure 13 shown, the flexible sleeve is composed of multiple sections and is sleeved independently.

[0091] In some embodiments, the box-lifting assembly 6 includes: clamping plates 61 on both sides, a vertical cylinder 62 for driving the lifting of the clamping plates 61, a horizontal cylinder 63 for driving the clamping plates 61 forward and backward, and a pawl 64 arranged at the lower end inside the clamping plates 61.

[0092] As Figure 5-10 shown; the vertical cylinder 62 is arranged on the mounting plate on the bracket 20, and a lifting plate 65 is arranged at its telescopic end, and the horizontal cylinder 63 is arranged on the lifting plate 65.

[0093] During operation, the height of the lifting plate 65 is adjusted by the vertical cylinder 62, and the movement of the clamping plates 61 is controlled by the horizontal cylinder 63; and the pawl 64 clamps the material box 4 to lift it.

[0094] Furthermore, guide rods are respectively arranged on both sides of the vertical cylinder 62 and the horizontal cylinder 63 to improve stability.

[0095] Preferably, two vertical cylinders 62 are in a group and are arranged oppositely, and the telescopic ends of the two vertical cylinders 62 are connected by a flange plate.

[0096] As Figure 10 shown, through the cooperation of the two vertical cylinders 62, it has a greater stroke and a faster moving speed, and can improve the overall operation efficiency.

[0097] Furthermore, a rubber pad 66 is arranged inside the clamping plate 61.

[0098] Furthermore, the pawl 64 is horizontally arranged, and a notch is arranged at its front end; to better position and clamp the material box 4; the conventional material box 4 has longitudinal and transverse ribs on the side, and the notch of the pawl 64 cooperates with it.

[0099] It should be noted that in order to ensure the center position of the material box, side guide strips are symmetrically arranged on the conveyor 1 or the automatic folding box machine 2.

[0100] As Figure 11As shown, bending segments are respectively arranged at the inlet and outlet ends of the side guide bars, with a flat segment in the middle, and the flat segments of the two side guide bars are corresponding and parallel.

[0101] In addition, in order to stack and lower the bins better, an outward-bending outer folding edge is also arranged above the flat segment of the side guide bar; for guiding when lowering the bin 4.

[0102] Furthermore, power components such as cylinders are arranged on the outer sides of the side guide bars to drive and adjust the distance between the two side guide bars to adapt to bins 4 of different specifications; it can be understood that generally only one specification of bin 4 is adopted, and in this case, the side guide bars can be directly set in a fixed installation form.

[0103] When stacking the bins 4:

[0104] Before the first bin 4 arrives, the lifting baffle 51 is lifted to form a block; at the same time, in cooperation with the side guide bars, the bin 4 is positioned; after the bin 4 is in place, the clamping plate 61 descends, aligns, and then moves inward to clamp the bin 4 and lift it; the lifting height is greater than the height of the bin 4;

[0105] After that, the second bin 4 is in place; the first bin 4 is lowered and placed on the second bin 4 to form a stack;

[0106] When two bins 4 need to be stacked, the clamping plate 61 withdraws, the lifting baffle 51 drops, and the two stacked bins 4 are conveyed away;

[0107] When it is necessary to continue stacking bins 4, the clamping plate 61 withdraws and releases the first bin 4; after that, the clamping plate 61 descends, aligns, and then moves inward to clamp the second bin 4; then, the second bin 4 together with the first bin 4 above it is lifted; similarly, the lifting height is greater than the height of the bin 4;

[0108] After that, the third bin 4 is in place; the second bin 4 is lowered and placed on the third bin 4 to form a stack;

[0109] When three bins 4 need to be stacked, the clamping plate 61 withdraws, the lifting baffle 51 drops, and the three stacked bins 4 are conveyed away;

[0110] When it is necessary to continue stacking bins 4, the clamping plate 61 withdraws and releases the second bin 4; after that, the clamping plate 61 descends, aligns, and then moves inward to clamp the third bin 4; then, the third bin 4 together with the two bins 4 above it is lifted; similarly, the lifting height is greater than the height of the bin 4;

[0111] And so on, forming the stacking of multiple layers of bins 4.

[0112] It should be noted that, for such a small height material box 4, two layers are generally stacked.

[0113] In some embodiments, sensors for sensing the material box 4 are provided on both sides of the inlet position of the bracket 20 so that when the material box 4 enters, the lifting baffle 51 can be lifted in time to form a limit position.

[0114] Similarly, a sensor for sensing the material box 4 is provided at the outlet of the bracket 20 and in front of the lifting baffle 51; after the material box 4 is basically in place, the three-fold arm 53 is optionally controlled to be lifted.

[0115] In addition, multiple layers of sensors for sensing stacked material boxes are provided on the inner side of the support 20 to obtain whether there is a material box 4 at a corresponding height.

[0116] In some embodiments, the stacker 3 is composed of: a main frame 30, a walking assembly 7, a lifting assembly 8, a telescopic clamping fork 9, an electric control cabinet 31, a power supply assembly 32, a ground rail 33, and a ceiling rail 34.

[0117] Among them, the main frame 30 is composed of several aluminum profiles, and various components are installed on it; the electric control cabinet 31 encapsulates the electrical control components and other structures inside it; the power supply component 32 adopts the form of a busbar and a collector, and the collector slides in contact in the busbar trough to supply power to the stacker; the ground rail 33 and the ceiling rail 34 both adopt conventional technical solutions.

[0118] In some embodiments, the walking assembly 7 includes: a mounting plate 70 , a servo motor 71 , a driving wheel 72 , a driven wheel 73 , a side guide wheel 74 , and an anti-dumping limit plate 75 .

[0119] The servo motor 71 is arranged below the electric control cabinet 31 and is connected to the driving wheel 72 to form a driving device; the remaining driven wheels 73 ensure the balance of movement; Figure 19 , 20 As shown, two driving wheels 72 are synchronously connected by a shaft and are matched with three sets of driven wheels 73.

[0120] The side guide wheels 74 are clamped on both sides of the ground rail 33 to prevent the stacker from tilting and improve the movement stability.

[0121] like Figure 17-20 As shown; two mounting plates 70 are a group, located on both sides above the ground rail 33; side guide wheels 74 and anti-dumping limit plates 75 are installed on the outside of a group of mounting plates 70; driving wheels 72 and driven wheels 73 are located on the inside of a group of mounting plates 70.

[0122] In addition, the ground rail 33 is made of an aluminum profile with steps, and the stacker is prevented from tilting by the cooperation between the anti-dumping limit plate 75 and the step surface.

[0123] In some embodiments, the lifting assembly 8 includes: a lifting drive motor 80, a belt drive wheel 81, and a lifting synchronous belt 82.

[0124] As Figure 21-23 shown; the lifting drive motor 80 is arranged above one side of the main frame 30 and is drivingly connected to a main shaft 83 extending front and rear. A belt drive wheel 81 is assembled at each end position of the main shaft 83; a secondary shaft 84 is arranged below the same side of the main frame 30, and a driven belt wheel 85 is assembled on each side of the secondary shaft 84; a synchronous belt wheel 86 is arranged above the other side of the main frame 30.

[0125] In addition, two lifting synchronous belts 82 are provided.

[0126] Wherein, one lifting synchronous belt 82 is respectively connected to the upper and lower end positions of the telescopic clamping fork 9 after cooperating with a belt drive wheel 81 and a driven belt wheel 85 up and down.

[0127] One end of the other lifting synchronous belt 82 is connected to the same side of the telescopic clamping fork 9, and after sequentially cooperating with the driven belt wheel 85, the belt drive wheel 81, and the synchronous belt wheel 86, it is connected to the other side of the telescopic clamping fork 9.

[0128] During use, by operating the lifting drive motor 80, the main shaft 83 is driven to rotate, and the two belt drive wheels 81 operate synchronously; as Figure 21 shown, the rear lifting synchronous belt 82 operates to pull the telescopic clamping fork 9; at the same time, the front lifting synchronous belt 82 operates to drive the telescopic clamping fork 9 via the synchronous belt wheel 86; thus, the lifting movement of the telescopic clamping fork 9 is realized.

[0129] Furthermore, the lifting assembly 8 further includes: a guide rail 87 arranged inside the main frame 30, and sliders 88 assembled on both sides of the telescopic clamping fork 9 and cooperating with the guide rail 87.

[0130] In some embodiments, the telescopic clamping fork 9 is in the form of a single-station double-extension position, including a frame, a telescopic arm, and a servo lever; it can directly adopt the existing technology on the market, and no improvement is made to it in this application.

[0131] Preferably, as Figure 24 shown; the telescopic arm is driven by a servo motor and is installed on the inner side frame of the frame, with a total of three sections; of course, it can also be set to a single section or one section; the servo lever includes four groups. When it is necessary to carry a material box, the servo drives the lever to rotate and contact the material box, and the material box is carried to the designated position by pushing and pulling.

[0132] The above example is in the form of a single-station double-extending position. For the same type of single-station single-extending position, double-station single-extending position, and double-station double-extending position, the existing technologies on the market can be selected according to actual needs.

[0133] As Figure 1-4 , shown in Figures 26 - 27;

[0134] This system adopts a modular design and uses the conveyor 1 and the stacker 3 to achieve seamless docking between the production workshop and the warehouse; uses the automatic folding box machine 2 to achieve the handling of the low-height bins 4; the entire system has the functions of warehousing and shelving, and outbound and off-shelving; that is, when the bin 4 is transported from the workshop to the warehouse, its main function is warehousing and shelving; when the bin 4 is transported from the warehouse to the workshop, its main function is outbound and off-shelving.

[0135] The operation principle of warehousing and shelving is as Figure 26 shown;

[0136] The conveyor 1 transports the bins 4 forward one by one. When the automatic folding box machine 2 detects that the bin 4 is about to arrive, the air cylinder drives the lifting baffle 51 to lift upward to prevent the bin 4 from moving forward; after reaching the position, it drives the three-fold crank arm 53 to lift upward; then, the box-lifting assembly 6 lifts the bin 4 upward, and the blocking assembly 5 retracts downward to the low position; when the second bin arrives, the blocking assembly 5 performs the same action process as described above; then, the box-lifting assembly 6 lowers the first bin 4, and the two bins 4 are stacked together. The box-lifting assembly 6 retracts to its original position, and the blocking assembly 5 descends to the low position; the stacked bins 4 continue to be transported forward.

[0137] The bin 4 is transported to the picking point of the stacker 3, and the telescopic clamping fork 9 is used to pull the bin 4 onto the load-carrying platform of the stacker; when the walking assembly 7 and the lifting assembly 8 drive the entire stacker 3 to move to the designated position on the shelf, the telescopic clamping fork 9 extends and pushes the bin 4 onto the shelf; the telescopic clamping fork 9 retracts into the stacker to complete the warehousing and shelving operation.

[0138] The operation principle of outbound and off-shelving is as Figure 27 shown;

[0139] The telescopic clamping fork 9 of the stacker 3 extends and pulls the bin 4 onto the load-carrying platform of the stacker; the walking assembly 7 and the lifting assembly 8 drive the entire stacker 3 to move to the discharging position; the telescopic clamping fork 9 pushes the bin 4 out of the load-carrying platform of the stacker onto the conveyor 1; the telescopic clamping fork 9 retracts into the stacker to complete the box discharging operation.

[0140] At this time, the conveyor 1 runs in reverse to automatically convey the stack of bins to the automatic bin unfolding machine 2. When the bin 4 is about to arrive, the cylinder drives the triple-fold crank arm 53 to lift upwards to prevent the stack of bins from moving forward. After reaching the position, the bin lifting assembly 6 lifts the upper bin 4 to separate the two bins 4. At this time, the lower bin 4 is placed on the conveyor 1, the triple-fold crank arm 53 contracts downwards, and the conveyor 1 executes the conveying instruction to convey the lower bin 4 forward.
