[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. The described embodiments are only part of the embodiments of the present application, not all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present application without creative work shall fall within the scope of protection of this application.

[0042] Example 1

[0043] like Figure 1 —9,

[0044] A staple stacking device comprises a feeding device 2, a buckle device 3, a conveying device 4, a stacking device 7 and a discharging device 8 which are arranged in sequence;

[0045] The feeding device 2 is installed at the end of the code nail conveying line 1 and is used to convey the code nails to the buckle flipping device 3;

[0046] The buckle flipping device 3 is used to buckle together the two groups of code nails delivered by the feeding device 2;

[0047] The conveying device 4 conveys the two sets of fastened code nails from the flipping device 3 to the stacking device 7;

[0048] A stacking device 7 is used to stack several groups of fastened coding nails together;

[0049] The discharging device 8 is used to transport the stacked stack of staples to the packaging station.

[0050] The feeding device 2 includes a workbench 21 for storing code nails and a first cylinder 22 for pushing the code nails on the workbench 21 in groups; the first cylinder 22 is fixedly connected to the workbench 21; and a first push plate 23 is installed on the cylinder rod of the first cylinder 22 with a guiding function.

[0051] like Figure 2-6 As shown, the flipping device 3 includes a 180-degree flip cylinder 31 fixedly connected to the workbench 21 and a material frame 32 fixedly connected to the rotating platform of the 180-degree flip cylinder 31; the material frame 32 is in the shape of a P, with the P-shaped opening facing the first push plate; a magnet 38 is provided on the bottom surface of the material frame 32;

[0052] The detailed structure of the material frame 32 is as follows:

[0053] The material frame 32 includes a base 33 fixedly connected to the rotating platform of the 180-degree turning cylinder 31, and a bottom plate 35 and a top plate 34 detachably connected to the base 33; a magnet 38 is located on the bottom plate 35;

[0054] The distance between the top plate 34 and the bottom plate 35 can be adjusted to accommodate different heights of code nails. The distance between the top plate 34 and the bottom plate 35 should be greater than the height of one code nail plus the thickness of one code nail (that is, the diameter of the steel wire that makes up the code nail) and less than 1.5 times the height of the code nail. If the distance between the two plates is too small, it will be difficult for the two groups of code nails to be plugged in and fastened together. If the distance is too large (more than 1.5 times), the two groups of code nails will easily come apart when pushing the two groups of code nails. When the code nails are just started to be pushed, the code nails on the bottom plate 35 are still attracted by the magnets 38, and the code nails on the top plate 34 are in a free state. If the distance between the two plates is too large, there is a risk of rollover. Tests have shown that when the distance is greater than 1.5 times the height of the code nails, the code nails will occasionally roll over.

[0055] like Figure 2 As shown, the center line of the material frame 32 is staggered with the center line of the first push plate 23. When the bottom plate 35 is turned over, the first set of code pins on the bottom plate 35 and the second set of code pins on the top plate 34 are staggered, and the second set of code pins are inserted and buckled into the first set of code pins (as shown in FIG. Figure 3 shown);

[0056] The offset distance between the center line of the material frame 32P and the center line of the first push plate 23 is greater than the diameter of a code nail wire and less than the width of a code nail; to avoid collision when the two sets of code nails are buckled and overlapped;

[0057] The conveying device 4 includes a second cylinder 41 for pushing out the two sets of coding pins fastened within the material frame 32, a conveying track 5 for receiving the two sets of coding pins pushed by the second cylinder 41, and a third cylinder 42 for pushing the coding pins from the conveying track 5 into the stacking device 7. A baffle 6 is provided at one end of the conveying track 5 near the third cylinder 42. The third cylinder 42 is vertically fixed to one side of the conveying track 5 to facilitate pushing the coding pins. The pushing direction of the second cylinder 41 is aligned with the length of the conveying track 5.

[0058] A notch is formed on the baffle 6 along its length, and the notch is used to limit the position of the hopper 72 of the stacking device 7, that is, the hopper 72 is raised and lowered along the notch to stack the staples.

[0059] The stacking device 7 includes a screw elevator 71 with a vertical lifting function, a 90-degree rotating cylinder 73 fixedly connected to the lifting rod of the screw elevator 71, and a silo 72 fixedly connected to the rotating table of the 90-degree rotating cylinder 73; the silo 72 is used to receive the code nails pushed by the third cylinder 42.

[0060] The silo 72 is provided with an initial position and a final position in the vertical direction. The height of the initial position is consistent with the height of the conveying track 5, and the final position is adapted to the discharge device 8.

[0061] The discharging device 8 includes a fourth cylinder 74 for pushing the whole stack of code nails in the stacking device 7, and a guide rail 81 for receiving the whole stack of code nails pushed by the fourth cylinder 74; stop bars 82 are provided at intervals on both sides of the guide rail 81; a push head 75 is provided at the end of the cylinder rod of the fourth cylinder 74, and the push head 75 is adapted to the hopper 72 and the whole stack of code nails.

[0062] The stop bars 82 are arranged at intervals, so that a whole stack of staples can be grabbed through the gaps between the stop bars 82, which is convenient for boxing.

[0063] The lifting silo 72 is adapted to the height of the guide rail 81;

[0064] After the 90-degree rotating cylinder 73 rotates 90 degrees, the bottom surface of the hopper 72 is flush with the top surface of the guide rail 81 of the discharging device 8, or the bottom surface of the hopper 72 is slightly higher than the top surface of the guide rail 81, which makes it easier for the fourth cylinder 74 to push the stack of staples in the hopper 72 onto the guide rail 81 for packaging the entire stack.

[0065] The first cylinder 22, the second cylinder 41, the third cylinder 42 and the fourth cylinder 74 in the present application can be replaced by oil cylinders or electric cylinders capable of linear motion;

[0066] The rotary cylinder of this application can adopt the popular rotary table on the market, which can be electric or hydraulic. For example, the hollow rotary platform is driven by a motor to realize automatic angle adjustment. The worm gear or gear transmission is finely processed, and the angle adjustment is unlimited. The precision shaft system design ensures high precision and large load capacity; the stepper motor and the transmission parts are connected by imported high-quality elastic couplings to eliminate spatial and processing shape and position errors. The outer ring scale of the rotary table is intuitive; the standard interface facilitates signal transmission; the manual handwheel configuration can be either electric or manual. Optional servo motor or stepper motor.

[0067] The working process of this application,

[0068] Several code pins with openings facing upward are transported by the code pin conveyor line 1 to the front of the first push plate 23. The first push plate 23 pushes a set number of code pins (five in the figure) onto the bottom plate 35, where they are attracted by the magnet 38. The first cylinder 22 drives the first push plate 23 to reset. The cylinder 31 then rotates 180 degrees to drive the material frame 32 to rotate, with the bottom plate 35 facing upward and the top plate 34 facing downward. After the bottom plate 35 drives the first group of code pins to rotate 180 degrees, the code pin openings face downward. The first cylinder 22 drives the first push plate 23 to push the second group of code pins onto the top plate 34. At this point, the second group of code pins are inserted into the first group of code pins.

[0069] The second cylinder 41 is activated, and the second cylinder 41 pushes the two sets of snap-fitting nails in the material frame 32 to overcome the suction force of the magnet 38 and then leave the material frame 32 and enter the conveying track 5 at the same time;

[0070] When the fastened code nails abut against the side of the baffle 6, the proximity switch on the baffle 6 receives a signal, the third cylinder 42 is activated, and the fastened group of code nails is pushed into the hopper 72. The screw elevator 71 drops to the height of one group of code nails, and the third cylinder 42 continues to push the second group of fastened code nails to the top of the first group of code nails. This cycle repeats until the set number of code nail groups (set to five layers in this embodiment) in the hopper 72 is reached. The third cylinder 42 stops pushing.

[0071] The 90-degree rotating cylinder 73 rotates 90 degrees, and the two ends of the opening of the hopper 72 face the fourth cylinder 74 and the guide rail 81 respectively. The fourth cylinder 74 is started to push the stacked stack of staples onto the guide rail 81 for use in the subsequent boxing process.

[0072] Example 2

[0073] The structure of this embodiment is basically the same as that of embodiment 1.

[0074] The difference is that

[0075] like Figure 4-5 As shown,

[0076] The distance between the top plate 34 and the bottom plate 35 is adjusted by the following structure to accommodate nails of different heights;

[0077] The base 33 is provided with a slide groove 36, and the top plate 34 and the bottom plate 35 are both provided with a rib plate 37, and the rib plate 37 is slidably connected to the slide groove 36;

[0078] The top plate 34 and the bottom plate 35 are both provided with strip-shaped holes, and the top plate 34 and the bottom plate 35 are both fixedly connected to the base 33 through the strip-shaped holes by bolts.

[0079] When the type of the code nail is changed, loosen the fastening bolts of the top plate 34 and the bottom plate 35 and the base 33, push the ribs 37 on the top plate 34 and the bottom plate 35 to the appropriate position along the slide groove 36, and since there are strip holes on the top plate 34 and the bottom plate 35, the strip holes can slide up and down on the bolts, and then tighten the bolts, and the top plate 34 and the bottom plate 35 can be fixed.

[0080] Example 3

[0081] The structure of this embodiment is basically the same as that of embodiment 1.

[0082] The difference is that

[0083] like Figure 1 / 9,

[0084] A material blocking plate 61 is provided at the top of the baffle 6. The material blocking plate 61 is used to prevent the staples from sliding out of the material bin 72 due to inertia after entering the material bin 72, thereby affecting the normal rotation of the material bin 72.

[0085] The above is only a preferred specific implementation method of the present application; however, the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed in the present application according to the technical solution and its improved conception of the present application, which should be covered by the protection scope of the present application.
