Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0036] The blanking equipment and blanking method according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] like Figures 1-12 As shown, the unloading equipment according to an embodiment of the present invention includes: at least one docking device 12, a pushing mechanism 33 and a conveying device 11, the docking device 12 is used to receive products; the pushing mechanism 33 is located on one side of the docking device 12; the conveying device 11 moves between the docking device 12 and the pushing mechanism 33 to convey the product from the docking device 12 to the pushing mechanism 33; a material box docking mechanism 34, the material box docking mechanism 34 carries a material box, the material box docking mechanism 34 drives the material box to perform horizontal and vertical movements, and when the material box is performing vertical movement, the material box is located behind the pushing mechanism 33 to receive the product pushed out from the pushing mechanism 33.

[0038] In this embodiment, there are two docking devices 12, and the pushing mechanism 33 is located between the two docking devices 12. The docking device 12 receives the processed product, and then grabs it onto the pushing mechanism 33 through the handling device 11.

[0039] like Figures 9 to 12 As shown, the pushing mechanism 33 includes: a support mechanism 30, a guide and limiting mechanism 32 and a pushing unit 31. The support mechanism 30 carries the product; the guide and limiting mechanism 32 is located at one end of the support mechanism 30, and the guide and limiting mechanism 32 guides and limits the passing product, and a material box is provided on the side of the guide and limiting mechanism 32 away from the support mechanism 30; the pushing unit 31 is provided on one side of the support mechanism 30, and the pushing unit 31 moves along the length direction of the support mechanism 30, pushing the product into the guide and limiting mechanism 32 for guiding and limiting, and then entering the material box.

[0040] The present invention carries and supports the product through the support mechanism 30, pushes the product toward the material box through the pushing unit 31, and uses the guide and limit mechanism 32 to guide and limit the product during the pushing process, ensuring that the product can accurately enter the material box, ensuring the pushing accuracy of the product, avoiding the problem of wrong pushing direction or product stacking, and realizing the continuity of the product in automatic pushing.

[0041] According to one embodiment of the present invention, the support mechanism 30 and the docking device 12 are both synchronous belt conveying mechanisms. The support mechanism 30 and the docking device 12 are driven by the same power source. In this embodiment, the power source is a motor, and the guide limiting mechanism 32 is located at the discharge end of the support mechanism 30.

[0042] According to one embodiment of the present invention, the guide and limit mechanism 32 includes: a base 320 and two adjustment components 325, and a support block 327 is provided on the base 320; the two adjustment components 325 are both installed on the base 320, and the two adjustment components 325 are relatively arranged on both sides of the support block 327; a guide limiter is provided on the adjustment component 325, and the guide limiter is located on the side of the adjustment component 325 facing the support block 327, and the guide limiter is used to guide and limit the product.

[0043] In other words, the adjustment component 325 is used to adjust the position of the guide limiter. When the product being pushed changes, the position of the guide limiter can be adjusted to adapt to different products, so that the guide limit can be performed for different products.

[0044] Furthermore, a first docking block 321 and a second docking block 322 are mounted on the support block 327 , a docking groove 323 is formed between the first docking block 321 and the second docking block 322 , and the discharge end of the support mechanism 30 is located in the docking groove 323 .

[0045] That is, the first docking block 321 and the second docking block 322 are respectively located on both sides of the support mechanism 30 , so as to ensure that the support mechanism 30 is aligned with the guide and limiting mechanism 32 .

[0046] In this embodiment, the adjustment assembly 325 includes: an adjustment seat 3253, an adjustment block 3254 and an adjustment screw 3255. A guide rod 3256 is vertically arranged on the adjustment seat 3253; the adjustment block 3254 is slidably sleeved on the guide rod 3256; the outer periphery of the adjustment screw 3255 is threadedly connected to the adjustment seat 3253, and one end of the adjustment screw 3255 is rotatably connected to the adjustment block 3254.

[0047] The guide limiter is installed on the adjustment block 3254. In this embodiment, there are two guide rods 3256. The adjustment block 3254 drives the guide limiter to move along the axis of the guide rod 3256. When the adjustment screw 3255 rotates, it drives the adjustment block 3254 to move up and down. When adjusted to the appropriate position, the adjustment screw 3255 stops rotating.

[0048] Preferably, the guide limiter includes a width limiter block 3251 and a height limiter block 3252. The width limiter block 3251 is installed on the side of the adjustment block 3254 facing the support block 327. The product is conveyed between the two width limiter blocks 3251. By changing the width of the width limiter block 3251, it can adapt to products of different widths. The height limiter block 3252 is installed on the side of the width limiter block 3251 facing the support block 327. The product is conveyed between the support block 327 and the height limiter block 3252. The height between the height limiter block 3252 and the support block 327 is adjusted by adjusting the adjusting screw 3255 to adapt to products of different heights. A photoelectric induction device is also provided above the support block 327. The photoelectric induction device can sense whether any product has entered the guide limiter mechanism 32.

[0049] More preferably, a support bearing 324 is provided below the height limit block 3252. The lower surface of the product is in rolling contact with the support bearing 324, and the distance between the lower surface of the height limit block 3252 and the support bearing 324 is greater than or equal to the thickness of the product. In this embodiment, the support bearing 324 is mounted on the second docking block 322 and the support block 327. The support bearing 324 provides rolling support for both sides of the product, preventing the product from tilting horizontally.

[0050] On this basis, the lower surface of the height limit block 3252 has a guide slope, and the distance between the guide slope and the upper edge of the support bearing 324 gradually decreases along the pushing direction. This design forms a bell-mouth structure, which can facilitate the product to enter the lower surface of the height limit block 3252.

[0051] According to one embodiment of the present invention, the pushing unit 31 includes: a vertical plate 311, a connecting block 313 and a screw rod 315, and a guide rail 312 is provided on the vertical plate 311; the connecting block 313 is slidably provided on the guide rail 312, and the connecting block 313 is connected to the pushing block 314, and the pushing block 314 is located above the support mechanism 30; the screw rod 315 is installed on one side of the vertical plate 311, and a screw nut 316 is sleeved on the screw rod 315, and the screw nut 316 and the connecting block 313 are connected by an elastic member 317.

[0052] That is, the screw rod 315 and the screw nut 316 form a power source, driving the connecting block 313 and the pushing block 314 to move along the guide rail 312, and the elastic member 317 can provide a buffer when obstacles occur during the pushing process.

[0053] Furthermore, both ends of the vertical plate 311 are provided with a limit member 318 and a photoelectric sensor 319. The limit member 318 is used to abut against the screw nut 316, and the photoelectric sensor 319 is used to determine whether the pushing unit 31 has reached the end point.

[0054] When the pushing mechanism 33 is working, the transport device 11 places the product on the support mechanism 30, and then the pushing unit 31 starts working. The pushing block 314 pushes the product to move toward the guide limit mechanism 32, and the product passes between the height limit block 3252 and the support block 327 and enters the material box.

[0055] like Figure 2 、 Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the material box docking mechanism 34 includes: a first material box support platform 344, a second material box support platform 345, a horizontal moving mechanism 341, a vertical moving mechanism 342 and a material box fixing mechanism 343, the first material box support platform 344 carries an empty material box; the second material box support platform 345 is located above the first material box support platform 344; the horizontal moving mechanism 341 is located on one side of the first material box support platform 344; the vertical moving mechanism 342 is installed on the horizontal moving mechanism 341, and the horizontal moving mechanism 341 drives the vertical moving mechanism 342 to move horizontally; the material box fixing mechanism 343 is used to clamp the material box, and the material box fixing mechanism 343 is installed on the vertical moving mechanism 342, and the vertical moving mechanism 342 drives the material box to move vertically.

[0056] The first material box supporting platform 344 is provided with a conveyor belt to transport the empty material box to the material box fixing mechanism 343 , and the horizontal moving mechanism 341 is a screw-nut mechanism.

[0057] According to one embodiment of the present invention, the vertical moving mechanism 342 includes: a first frame 3421, a guide rail slider mechanism 3422 and a first screw drive device 3423, the guide rail slider mechanism 3422 is arranged in the first frame 3421; the first screw drive device 3423 is arranged in the first frame 3421; the material box fixing mechanism 343 includes: a second frame 3431, a guide column and guide sleeve mechanism 3434, a second screw drive device 3435, a lower clamping block 3432 and an upper clamping block 3433, the second frame 3431 is connected to the guide rail slider mechanism 3422 and the first screw drive device 3423; the guide column and guide sleeve mechanism 3434 is arranged in the second frame 3431; the second screw drive device 3435 is arranged in the second frame 3431; the lower clamping block 3432 is installed at the lower end of the second frame 3431; the upper clamping block 3433 is connected to the second screw drive device 3435 and the guide column and guide sleeve mechanism 3434.

[0058] In other words, the first material box support platform 344 is used to place empty material boxes, and the second material box support platform 345 is used to place material boxes filled with products. After the material box fixing mechanism 343 clamps the material box, the horizontal moving mechanism 341 and the vertical moving mechanism 342 jointly drive the material box to move. The conveyor belt on the first material box support platform 344 moves the material box toward the material box fixing mechanism 343, and the upper clamping block 3433 approaches the lower clamping block 3432, thereby clamping the material box. The vertical moving mechanism 342 drives the material box to move upward. After the pushing mechanism 33 pushes a product into the material box, the material box moves upward a certain distance to facilitate the next product to be pushed into the material box. After the material box is full, it is transported to the second material box support platform 345.

[0059] like Figures 6 to 8 As shown, the handling device 11 includes: a gantry 121, a linear motion mechanism 122 and a grabbing mechanism 123. The linear motion mechanism 122 is installed on the gantry 121; the grabbing mechanism 123 is installed on the output end of the linear motion mechanism 122. The linear motion mechanism 122 drives the grabbing mechanism 123 to move between the docking device 12 and the pushing mechanism 33.

[0060] According to one embodiment of the present invention, the gripping mechanism 123 includes: a cylinder 110 and a plurality of gripping units, the cylinder 110 is installed on the linear motion mechanism 122, and a mounting bar 111 is provided on the output end of the cylinder 110, and the mounting bar 111 is parallel to the length direction of the product; the plurality of gripping units are arranged at intervals along the length direction of the mounting bar 111, and the gripping units can be fine-tuned in position along the length direction of the mounting bar 111; the end of the gripping unit facing the product is formed as a suction cup 1121, and an elastic member is provided between the suction cup 1121 and the mounting bar 111, and the extension and contraction direction of the elastic member is parallel to the driving direction of the cylinder 110.

[0061] In this embodiment, there are four grabbing units. When grabbing, the arrangement direction of the four grabbing units, the length direction of the mounting bar 111, and the length direction of the product are kept consistent. The grabbing units at both ends are used to grab the two ends of the product, and the grabbing unit in the middle is used to grab the middle of the product. In this way, long strips of products can be grabbed at multiple points, and the products can be kept in a straight state when grabbed, avoiding product breakage or bending; a suction cup 1121 is used to adsorb the product, and an elastic part is used to buffer the pressure of the approaching parts. Compared with the method of gripping with claws, this application avoids hard contact with the product and protects the product.

[0062] On this basis, the mounting bar 111 is provided with a plurality of adjustment holes 1111, each corresponding to a plurality of gripping units. The length of the adjustment holes 1111 is parallel to the length of the mounting bar 111, and the gripping units are positionally adjustable within the adjustment holes 111. In this embodiment, there are four adjustment holes 1111, and the gripping units can be finely adjusted within the adjustment holes 1111 along the length of the adjustment holes 1111.

[0063] In other words, by adjusting the position of the grabbing unit, it is ensured that each grabbing unit is adsorbed on a different position of the product, ensuring that the product is evenly stressed.

[0064] According to one embodiment of the present invention, the gripping unit includes a suction rod 1123, one end of which is connected to the suction cup 1121, and the other end of which is connected to the vacuum generator. The negative pressure value of the vacuum generator is monitored to determine whether the suction cup 1121 has sucked the product.

[0065] In other words, it is only necessary to monitor the negative pressure value of the vacuum generator to effectively determine whether each suction cup 1121 has adsorbed the product. If it has not been adsorbed, it will be adsorbed again. If it fails to adsorb for multiple times, an alarm will be issued.

[0066] Furthermore, a guide sleeve 1125 is slidably sleeved on the suction rod 1123, and the guide sleeve 1125 is clamped in the adjustment hole 1111. Furthermore, the elastic member is a spring 1122, which is sleeved on the suction rod 1123, with the lower end of the spring 1122 connected to the suction rod 1123 and the upper end of the spring 1122 connected to the guide sleeve 1125.

[0067] That is, when the cylinder 110 drives the grabbing unit close to the product, the suction cup 1121 contacts the product. At this time, the spring 1122 contracts, and the suction rod 1123 and the guide sleeve 1125 slide in opposite directions. This ensures that the suction cup 1121 maintains a certain pressure with the product, avoids hard contact, and improves the adsorption effect.

[0068] According to one embodiment of the present invention, the guide sleeve 1125 includes a cylindrical portion and a flange portion. The cylindrical portion is positioned within the adjustment hole 1111 and is fitted with a locking nut 1124. The mounting strip 111 is clamped between the flange portion and the locking nut 1124. The cross-section of the guide sleeve 1125 and the locking nut 1124 forms an "I" shape. When the locking nut 1124 is tightened, the locking nut 1124 and the flange portion clamp the mounting strip 111. Loosening the locking nut 1124 allows fine-tuning of the position of the grabbing unit within the adjustment hole 1111.

[0069] Among them, there are two locking nuts 1124, and the two locking nuts 1124 fit together. In order to improve the connection stability, two locking nuts 1124 are used to fix the guide sleeve 1125. The two locking nuts 1124 are locked with each other to avoid loosening after long-term use.

[0070] When the conveying device 11 is working, the distance between each grabbing unit is pre-adjusted so that the grabbing unit is fully adapted to the product. The conveying device drives the grabbing mechanism to move above the product, the cylinder 110 moves downward, the suction cup 1121 contacts the product, the cylinder 110 continues to move downward, the spring 1122 is compressed, the cylinder 110 moves upward, the suction cup 1121 drives the product to move upward to a certain height, and the conveying device transports the product to other places. During the whole process, the negative pressure value of the vacuum generator is monitored to determine whether the product falls off the suction cup 1121.

[0071] The present invention also discloses a material unloading method, which uses the above-mentioned unloading equipment to unload products, including the following steps: Step 1: The docking device 12 receives the product delivered by the front-end equipment, and the conveying device 11 conveys the product to the pushing mechanism 33; Step 2: The material box connecting mechanism 34 moves the material box to the rear of the pushing mechanism 33; Step 3: The pushing mechanism 33 guides the product and pushes the product into one layer of the material box; Step 4: The material box connecting mechanism 34 drives the material box to move up and down, repeating steps 1 to 3, and the pushing mechanism 33 pushes the next product into another layer of the material box; Step 5: After the material box is full of products, the material box connecting mechanism 34 re-grabs the empty material box for unloading.

[0072] By utilizing the blanking equipment and blanking method of the present invention to blank products, the degree of automation is improved, the blanking efficiency and the accuracy of loading products into the material box are improved, the quality of the products is guaranteed, and the problem of bumps and damages to the products is avoided.
