Description

Technical Field

[0001] This invention relates to the field of sheet metal processing machinery and equipment, and more specifically, to a sheet metal stacking device with a sheet metal sorting mechanism. Background Technology

[0002] High-end book covers, diaries, children's book boxes, and other hard-shell products manufactured in China all require smaller cardboard sheets. These smaller sheets need to be cut from larger cardboard sheets, which requires a board cutting machine to slit the large cardboard raw materials into smaller sizes suitable for subsequent processes. When the board cutting machine processes the large cardboard sheets, it involves feeding the large cardboard, the first cut, conveying, the second cut, conveying the smaller sheets, and sorting. However, existing board cutting machines require manual sorting and packaging after cutting; instead of using machinery to neatly cut the sheets, the cut sheets are simply allowed to fall off, resulting in a scattered and messy mess. These sheets then need to be manually stacked, stored, or transported to subsequent processing machines by workers. This directly increases the labor intensity of workers and also increases labor costs.

[0003] Currently, Chinese patent CN209551882U discloses a board material sorting device for a board slitting machine. It is located at the discharge end of the slitting machine and includes a board sorting mounting frame and a board sorting conveyor belt wound around the board sorting mounting frame for conveying the slit board material. The board sorting mounting frame is provided with a board sorting conveyor table for the board sorting conveyor belt to be wound. The end of the board sorting conveyor table near the slitting machine is rotatably connected to the board sorting mounting frame. The board sorting mounting frame is provided with a board sorting rotation mechanism that can drive the board sorting conveyor table to rotate around the rotation axis of the board sorting mounting frame. After the board sorting conveyor belt drops the board material, the board sorting rotation mechanism can drive the end of the board sorting conveyor table away from the slitting machine to move in the height direction. This device can gradually increase the height of the sheet material dropping end, so that the second batch of sheet material can be stacked on the first batch of sheet material, thereby realizing automatic dropping and stacking of sheet material. However, when the sheet material is dropped at the dropping end, there are gaps between the sheet materials, and the sheet material may shift or rotate during dropping, which affects the neatness of the stacking of the sheet material and causes problems such as collapse and tipping of the stacked sheet material in the future.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figure 1-6As shown, a board sorting mechanism for a stacking device includes a board sorting conveyor 1 and a board sorting conveyor belt 2 rotatably connected to the board sorting conveyor 1 for conveying the slit board material. Both sides of the material dropping end of the board sorting conveyor 1 are provided with sorting plates 3 for transverse sorting of the board material, and a transverse drive assembly 4 provided on the board sorting conveyor 1 for pushing the sorting plates 3. A sorting block 83 is slidably connected to the material dropping end of the board sorting conveyor 1 for longitudinal sorting of the board material, and a longitudinal drive assembly 9 provided on the board sorting conveyor 1 for pushing the sorting block 83. The sorting block 83 is located below the board sorting conveyor 1. The longitudinal drive assembly 9 can drive the sorting block 83 to slide back and forth along the length direction of the board sorting conveyor belt 2. The transverse drive assembly 4 can drive the two sorting plates 3 to move closer or further apart along the width direction of the board sorting conveyor belt 2.

[0026] When the board sorting conveyor belt 2 conveys the slit boards onto the pallet for stacking, the longitudinal drive component 9 can drive the sorting block 83 to move longitudinally closer to the stacked boards and perform longitudinal pushing and slapping to eliminate longitudinal gaps in the stacked boards, thereby playing the role of longitudinally sorting the stacked boards. Meanwhile, the two sorting plates 3 are located on both sides of the board sorting conveyor belt 2 and can move closer or further away from each other under the action of the transverse drive component 4, thereby achieving the function of pushing and slapping the boards falling from the dropping end of the board sorting conveyor belt 2 from both sides towards the center, thereby playing the role of transversely sorting the stacked boards. Therefore, the setting of the board sorting mechanism effectively improves the neatness of the board stacking, thereby helping to avoid the collapse and tipping of the stacked boards.

[0027] The unloading end of the slab conveyor 1 is slidably connected to a slab mounting bracket 5 for mounting the slab 3. The sliding direction of the slab mounting bracket 5 on the slab conveyor 1 is towards or away from the unloading end of the slab conveyor 1. The slab conveyor 1 is also equipped with an adjustment component 6 that can adjust and lock the position of the slab mounting bracket 5 on the slab conveyor 1. The sliding arrangement of the slab mounting bracket 5 allows for adjustment of the working position of the slab 3, thereby improving the flexibility and applicability of the slab sorting mechanism.

[0028] The control component 6 includes a rack 61 mounted on the slab mounting frame 5 and a gear 62 rotatably connected to the slab conveyor table 1. The gear 62 meshes with the rack 61, and the length of the rack 61 extends along the sliding direction of the slab mounting frame 5 on the slab conveyor table 1. During the rotation of the gear 62, the slab mounting frame 5 can slide on the slab conveyor table 1 via the meshing rack 61. The structure is simple and easy to implement, allowing for convenient and flexible control of the working position of the slab 3. Furthermore, the control is convenient and fast, which helps improve work efficiency.

[0029] The board mounting frame 5 is slidably connected to the board conveyor table 1 on both sides of its width, and adjustment components 6 are provided on both sides of the board mounting frame 5, which helps to improve the stability and accuracy of the board mounting frame 5 sliding on the board conveyor table 1; the two gears 62 on both sides of the board mounting frame 5 are coaxially arranged and the two gears 62 are coaxially fixedly connected to a synchronous shaft 63, which can realize synchronous control of the two gears 62, thereby further improving the sliding stability and convenience of the board mounting frame 5; a drive handwheel 64 for driving the gears 62 to rotate is provided on the synchronous shaft 63, which can improve the convenience of driving the gears 62 to rotate.

[0030] A locking assembly 7 for securing the synchronous shaft 63 is provided on the board conveyor 1. The locking assembly 7 includes two locking arms 71, one end of which is fixed to the board conveyor 1. The locking arms 71 are located on opposite sides of the synchronous shaft 63, with a gap between them. A locking screw 72 for adjusting the gap width is provided at the end of each locking arm 71 that is fixed to the board conveyor 1 away from it. A handle 73 is provided on the locking screw 72. One end of each locking arm 71 is fixed to the board conveyor 1. The other end of one locking arm 71 has a through hole for the locking screw 72 to pass through, and the other end of the other locking arm 71 has a screw hole for the locking screw 72 to be screwed into. When the locking screw 72 is rotated by the handle 73, the gap width can be adjusted, thereby facilitating the clamping and fixing of the synchronous shaft 63 and limiting the position of the board mounting bracket 5.

[0031] A mounting slide 51 for mounting the sorting plates 3 is slidably connected to the sorting plate mounting frame 5. The sliding direction of the mounting slide 51 on the sorting plate mounting frame 5 is set along the width direction of the sorting plate conveying table 1. A locking component for locking the mounting slide 51 on the sorting plate mounting frame 5 is provided between the mounting slide 51 and the sorting plate mounting frame 5. The setting of the mounting slide 51 can adjust the working distance between the two sorting plates 3, so that it can be used for different specifications of plates, thereby improving the flexibility and applicability of the sorting mechanism.

[0032] The lateral drive assembly 4 includes a lateral drive cylinder 41 for driving the material handling plate 3 and a controller 42 for controlling the intermittent movement of the lateral drive cylinder 41. The lateral drive cylinder 41 is mounted on the mounting slide 51, and the material handling plate 3 is mounted on the piston rod of the lateral drive cylinder 41. Both the lateral drive cylinder 41 and the controller 42 are known technologies and are conventionally designed. The controller 42 can control the lateral drive cylinder 41 to drive the material handling plate 3 to move intermittently, thereby enabling continuous intermittent patting of the stacked plates, which helps to improve the neatness of the stacked plates.

[0033] The longitudinal drive assembly 9 includes a longitudinal drive cylinder 91 hinged to the slab conveyor 1, a rotating arm 92 hinged to the slab conveyor 1, and a drive arm 93 hinged between the rotating arm 92 and the slab block 83. The piston rod of the longitudinal drive cylinder 91 is hinged to the rotating arm 92. During the reciprocating swing of the rotating arm 92 driven by the longitudinal drive cylinder 91, the slab block 83 can be driven to slide back and forth via the drive arm 93. During the reciprocating sliding of the piston rod pushed by the longitudinal drive cylinder 91, the rotating arm 92 can be driven to swing back and forth around the hinge point with the slab conveyor 1, thereby driving the slab block 83 to slide back and forth via the drive arm 93. The structure is simple and easy to implement, and it can easily realize the drive control of the slab block 83.

[0034] A material handling slide 8 for installing material handling blocks 83 is slidably connected to the material handling conveyor 1. Both sides of the material handling slide 8 are slidably connected to the material handling conveyor 1. Two rotating arms 92 and two driving arms 93 are provided and located on both sides of the material handling slide 8. A synchronous rotating shaft 94 is provided at the hinge of the two rotating arms 92 on the material handling conveyor 1. A swing arm 95 is provided on the synchronous rotating shaft 94 and is hinged to the piston rod of the longitudinal driving cylinder 91. During the process of the longitudinal driving cylinder 91 driving the synchronous rotating shaft 94 to reciprocate through the swing arm 95, it can drive the two rotating arms 92 to reciprocate synchronously. Both sides of the material handling carriage 8 are slidably connected to the material handling conveyor 1, and both sides are equipped with rotating arms 92 and drive arms 93, which can realize the smooth sliding of the material handling carriage 8 by the longitudinal drive component 9. The synchronous rotating shaft 94 can realize the synchronous rotation of the two rotating arms 92, which is beneficial to improve the rotation synchronization of the two rotating arms 92, and thus improve the sliding stability of the material handling carriage 8; at the same time, it can also reduce the number of longitudinal drive cylinders 91 required.

[0035] Multiple material sorting blocks 83 are arranged at intervals along the width of the board sorting conveyor table 1. Multiple board sorting conveyor belts 2 are also arranged at intervals along the width of the board sorting conveyor table 1. The board sorting conveyor belts 2 and material sorting blocks 83 are staggered. This ingenious design effectively combines the material sorting blocks 83 with the board sorting conveyor belts 2. Therefore, while not affecting the conveying of board materials by the board sorting conveyor belts 2, it also improves the sorting effect of the material sorting blocks 83 in pushing and patting the board materials, greatly enhancing the flexibility and applicability of the board sorting mechanism.

[0036] The material handling carriage 8 includes a material handling slide 82 slidably connected to a slide rail 11 mounted on the material handling conveyor table 1, and a material handling mounting plate 81 detachably connected to the material handling slide 82. Material handling blocks 83 are mounted on the material handling mounting plate 81. Bolts are screwed onto the material handling slide 82. The material handling mounting plate 81 has a groove for the bolts to pass through, and the length of the groove is along the length of the material handling conveyor belt 2. This configuration allows for adjustment of the working position of the material handling mounting plate 81, thereby adjusting the working range of the material handling blocks 83 and greatly improving the flexibility and applicability of the material handling mechanism.

[0037] The material handling carriage 8 is equipped with a connecting rod 84 that slides and connects to the material handling block 83. The connecting rod 84 is vertically downward, and a limiting structure is provided between the connecting rod 84 and the material handling block 83 to prevent the material handling block 83 from slipping off the connecting rod 84. One end of the connecting rod 84 can be fastened to the material handling carriage 8 with screws, and the other end of the connecting rod 84 can be equipped with a limiting rod, which is perpendicular to the connecting rod 84. The material handling block 83 is provided with a limiting groove for the limiting rod to slide. The limiting rod can slide along the length of the limiting groove, thereby enabling the material handling block 83 to slide along the length of the connecting rod 84 without slipping off the connecting rod 84. This design enables the material handling block 83 to slide up and down, avoiding collisions between the material handling block 83 and the pallet when the dropping end of the material handling conveyor belt 2 approaches the pallet. The structural design is ingenious.
