[0025] Among them, the product 21 is received and transported by the frame 1, and four silo mechanisms 3 and corner protection transfer mechanisms 4 are provided, two by two in a group, symmetrically distributed on both sides of the frame 1 (that is, symmetrically distributed on both sides of the product 21); each corner protection transfer mechanism 4 is equipped with a silo mechanism 3, and most of the products 21 have four corners. Therefore, after the four corner protection transfer mechanisms 4 take materials from the corresponding silo mechanisms 3, the paper corner protectors 22 can be simultaneously moved to the four corners of the product 21, which is convenient for the subsequent packaging of the product 21 and greatly improves the work efficiency of the upper corner protection.

[0026] like Figure 2-Figure 4 As shown, the silo mechanism 3 includes a frame 31 located on one side of the frame 1, and a plurality of silo assemblies equidistantly distributed along the X-axis direction are arranged on the inner side of the frame 31. The silo assemblies are used to provide paper corner protectors 22, and a plurality of silo assemblies can simultaneously store paper corner protectors 22 of multiple different specifications for selection by the corner protector transfer mechanism 4.

[0027] The silo assembly includes a bottom plate 32, a slide seat 33, a positioning assembly 34, a silo plate 35, a push plate 36, a chain 37, a hook 38, a spring 39 and a limit assembly.

[0028] As mentioned above, the base plate 32 parallel to the Y-axis direction is fixedly installed at the bottom of the inner side of the frame 31, the slide 33 is slidably installed on the base plate 32, the positioning assembly 34 is fixed at the front end of the slide 33, the storage plate 35 is fixedly installed at the rear end of the slide 33, and the push plate 36 is slidably installed on the slide 33 and is located between the positioning assembly 34 and the storage plate 35; the spring 39 is arranged on the slide 33, and the spring 39 can drive the push plate 36 to move horizontally along the Y-axis direction close to the positioning assembly 34; the hook 38 is fixedly installed on the push plate 36, one end of the chain 37 is connected to the storage plate 35, and the other end can be connected to the hook 38.

[0029] A slide rail 361 parallel to the Y-axis direction is also fixedly installed on the slide seat 33, a slider 362 is slidably installed on the slide rail 361, and the bottom of the push plate 36 is fixedly connected to the slider 362; the paper corner protector 22 is located between the push plate 36 and the positioning assembly 34, and the spring 39 is located between the push plate 36 and the warehouse plate 35. Therefore, under the elastic force of the spring 39, the overlapping paper corner protectors 22 are firmly pressed between the positioning assembly 34 and the push plate 36. The push plate 36 adopts a contoured structure with the same inner contour as the paper corner protector 22, and fits firmly with the rearmost paper corner protector 22.

[0030] A slide groove is also provided on the slide seat 33, and the slide rail 361, the slider 362 and the spring 39 are all arranged in the slide groove, and the slide groove can also provide a limit for the paper corner protector 22 when it is placed.

[0031] By cooperating with the chain 37 and the hook 38, the push plate 36 can be connected to the storage plate 35, so that the push plate 36 can be fixed on the slide seat 33, so as to facilitate the replenishment of paper corner protectors 22 materials between the push plate 36 and the positioning assembly 34, which can save manpower and improve work efficiency; and handles are provided on the storage plate 35 and the push plate 36 to facilitate the staff to pull the storage plate 35 or the push plate 36.

[0032] The positioning assembly 34 serves to block the paper corner protector 22 and to position the paper corner protector 22 , and includes a support 341 fixedly mounted on the front end of the slide 33 , a top plate 342 is mounted on the top of the support 341 , a V-shaped wheel 343 is rotatably mounted on the front side of the support 341 , and a V-shaped groove is provided on the top plate 342 .

[0035] The mounting seat 63 is made of angle iron and fixedly installed on the top of the frame 31; the connecting rod 62 is made of profile and is connected to the mounting seat 63 by screws, and according to the height of the paper corner protector 22, the mounting seat 63 can be screwed and fixed in the corresponding position, thereby realizing the function of the limit plate 61 being able to be raised and lowered; this structure enables the silo mechanism 3 to adapt to products 21 of different heights, is less restricted by space, and can meet most of the vertical corner protection situations on the market.

[0036] The lower end of the paper corner protector 22 is slidably embedded in the slide groove of the slide seat 33, and the upper end is embedded in the guide groove of the limit plate 61. With the push of the push plate 36, it can ensure that the paper corner protector 22 always remains in a vertical state. Therefore, the limit assembly can not only adjust the height according to the paper corner protector 22, but also play a guiding role in the automatic filling of the paper corner protector 22.

[0037] Loading process of silo mechanism 3: First, open the locking device between the bottom plate 32 and the slide 33, and pull the slide 33 out from the inside of the frame 31; secondly, pull the push plate 36 to compress the spring 39, and hang one end of the chain 37 on the hook 38, so that the push plate 36 is fixed on the slide 33, so that there is enough storage space between the push plate 36 and the positioning assembly 34; then place the paper corner protectors 22 stacked together horizontally between the push plate 36 and the positioning assembly 34, and then disengage the chain 37 from the hook 38. Under the thrust of the spring 39, the push plate 36 pushes the paper corner protectors 22 to rest against the V-groove and V-wheel 343 of the positioning assembly 34; finally, push the slide 33 back into the frame 31 and close the locking device again.

[0038] When the frontmost paper corner protector 22 is taken away, the spring 39 pushes the remaining paper corner protectors 22 forward by one position through the push plate 36, thereby realizing automatic filling, so as to facilitate the next time the corner protectors are taken away.

[0039] Among them, the X, Y, and Z axes are perpendicular to each other in space, and the X-axis direction is the arrangement direction of different silo components on the same silo mechanism 3, the Y-axis direction is the direction in which the corner protector head 5 moves toward the product 21 when installing the corner protector, that is, the direction in which the slide 33 is pulled along the bottom plate 32 relative to the frame 31, and the Z-axis direction is perpendicular to the ground supporting the frame 1.

[0040] Embodiment 2

[0041] On the basis of the first embodiment, the present invention further proposes a specific structure of the corner protection transport mechanism 4.

[0042] like Figure 5-Figure 8 As shown, the corner guard transfer mechanism 4 includes a bracket 41 connected to the frame 31, a Y-axis linear module 42 is installed on the bracket 41, an output end of the Y-axis linear module 42 is connected to a slide 43, an X-axis linear module 44 is installed on the slide 43, and a corner guard head 5 for grabbing the paper corner guard 22 is installed at the output end of the X-axis linear module 44.

[0043] The Y-axis linear module 42 is parallel to the Y-axis direction, the X-axis linear module 44 is parallel to the X-axis direction, and the slide 43 is used to connect the Y-axis linear module 42 and the X-axis linear module 44, that is, under the joint action of the X-axis linear module 44 and the Y-axis linear module 42, the corner protection head 5 can move horizontally along the X-axis and Y-axis directions; so that the corner protection head 5 can move along the X-axis direction to grab the paper corner protectors 22 in different silo components, and after the corner protection head 5 grabs the paper corner protector 22, it can also promptly and accurately transport it to the corners of the product 21.

[0044] The corner protection machine head 5 includes a Y-axis linear component 51 installed at the output end of the X-axis linear module 44, the output end of the Y-axis linear component 51 is connected to a central connecting plate 52, the central connecting plate 52 is rotatably connected to a vertical plate 53 via a rotating shaft 56, the rotating shaft 56 is parallel to the Z-axis direction, and a rotating drive component 57 for driving the rotating shaft 56 to rotate is also provided on the central connecting plate 52; a Z-axis telescopic component 55 is installed on the vertical plate 53, the output end of the Z-axis telescopic component 55 is connected to a suction head component 54, and the suction head component 54 is also slidably connected to the vertical plate 53.

[0045] The Y-axis linear component 51 is parallel to the Y-axis direction, and the Z-axis telescopic component 55 is parallel to the Z-axis direction; since the suction head assembly 54 does not need to rotate continuously in the same direction, the rotary drive assembly 57 adopts a rotary cylinder, and the rotary cylinder is connected to the rotating shaft 56 through a belt transmission structure, that is, the rotary cylinder can transmit the torque to the rotating shaft 56 through the belt transmission structure to drive the vertical plate 53 and the suction head assembly 54 to rotate.

[0046] Among them, the X-axis linear module 44, the Y-axis linear module 42, the Y-axis linear assembly 51, and the Z-axis telescopic assembly 55 are all existing technologies and can output linear displacements in corresponding directions; and in order to further reduce the space occupied by the corner protection machine when working, a part of the bracket 41 is located below the frame 31.

[0047] In addition, in order to prevent the paper corner protector 22 from falling due to collision vibration caused by the rotation of the vertical plate 53, a hydraulic buffer is also provided on the middle connecting plate 52, and its output end can abut against the vertical plate 53 to ensure that the vertical plate 53 will not vibrate violently during the rotation to two positions.

[0048] The suction head assembly 54 includes a support plate 541 slidably connected to the vertical plate 53, and the support plate 541 is also connected to the output end of the Z-axis telescopic assembly 55. The inner side of the support plate 541 is provided with a suction cup 542 that adheres to the outer side of the paper corner protector 22 and can adsorb and fix it.

[0049] The support plate 541 adopts a C-shaped structure, and photoelectric distance sensors are provided at both ends thereof; the inner side of the suction cup 542 can fit tightly with the outer side of the paper corner protector 22. When the suction cup 542 fits with the paper corner protector 22, the vacuum negative pressure generated by the external air pump is transmitted to the end of the suction cup 542, thereby achieving the purpose of adsorbing the paper corner protector 22.

[0050] In order to enable the suction head assembly 54 to accurately adjust its position with the paper corner protector 22 or the paper corner protector 22 and the product 21, an X-axis linear assembly 441 is also provided at the output end of the X-axis linear module 44. The X-axis linear assembly 441 has the same structure as the Y-axis linear assembly 51, and the Y-axis linear assembly 51 of the corner protector head 5 is installed at the output end of the X-axis linear assembly 441, and the X-axis linear assembly 441 is parallel to the X-axis direction. The X-axis linear assembly 441 cooperates with the Y-axis linear assembly 51 to achieve fine-tuning of the position of the suction head assembly 54, so as to ensure that the suction cup 542 is accurately fitted on the paper corner protector 22, while ensuring that the paper corner protector 22 can be accurately fitted at the corners of the product 21.

[0051] Corner protection workflow: The corner protector head 5 is driven by the X-axis linear module 44 to move to the corresponding silo assembly, and the X-axis linear assembly 441 and the Y-axis linear assembly 51 drive the suction head assembly 54 to move and fine-tune along the X and Y axis directions, and confirm the positions of the suction cup 542 and the paper corner protector 22 through fixed-distance photoelectricity, and determine whether the suction is in place by judging the vacuum value; when the suction head assembly 54 sucks the paper corner protector 22, the suction head assembly 54 moves upward along the Z axis under the lifting of the Z-axis telescopic assembly 55, and the paper corner protector 22 is taken out of the silo; then the rotary drive assembly 57 drives the vertical plate 53 to rotate to achieve a 180-degree turn of the paper corner protector 22. During this process, the hydraulic buffer is used for buffering to prevent the paper corner protector 22 from falling due to impact.

[0052] Corner guard placement workflow: After taking out the paper corner protector 22, the Z-axis telescopic assembly 55 is lowered to a low position, and the corner protector head 5 is moved to the corner of the product 21 by the drive of the X-axis linear module 44 and the Y-axis linear module 42. The fixed-distance photoelectric servo is positioned through the photoelectric characteristic, and then the position is adjusted through the X-axis linear assembly 441 and the Y-axis linear assembly 51, and finally accurate upper corner protection is achieved.

[0053] When fine-tuning the position, first determine one of the distances of the paper corner protector 22 relative to the corner of the product 21 in the X-axis or Y-axis direction through the fixed-distance photoelectric device, and cooperate with the corresponding X-axis linear component 441 or Y-axis linear component 51 to make one side of the paper corner protector 22 fit with the side of the product 21; then determine the distance of the paper corner protector 22 relative to the corner of the product 21 in the other direction, cooperate with the corresponding linear component to drive the paper corner protector 22 to move into place, and finally complete the upper corner protection.

[0054] To sum up, the vertical corner protection machine proposed in the present invention, in which the silo component of the silo mechanism 3 adopts pull-out type loading, and different silo components can load paper corner protectors 22 of different specifications. In conjunction with the corner protection transfer mechanism 4, it can automatically load corner protectors of various specifications, can adapt to products 21 of different heights, is less restricted by space, and can thus meet most of the vertical corner protection needs on the market.
