Description

Technical Field

[0001] The invention relates to the technical field of stone processing, and specifically provides a conveying device for processing marble slabs. Background Art

[0002] As a common building decorative panel, marble slabs need to go through a series of processing such as cutting, grinding, polishing, and surface treatment. Some marble slabs also need to be treated with adhesive backing to improve their impermeability, crack resistance, and waterproofness, thereby improving the overall strength and decorativeness of the marble slabs.

[0003] In the process of processing marble slabs, the marble slabs need to be automatically conveyed to improve the production and processing efficiency. For example, after the adhesive backing processing is completed, the marble slabs need to be conveyed and stacked to facilitate subsequent transfer and stacking or batch packaging; when stacking the marble slabs, you can choose to stack them horizontally or vertically.

[0004] Vertical stacking of marble slabs is a common stacking method in existing processing. Generally, a turning table is used to turn the marble slabs from a horizontal state to a vertical state, so that the slabs are stacked one by one. The side of the turning table is generally provided with a lower supporting structure, so that the marble slabs first fall on the lower supporting structure during the turning process, and then are further placed on the stacking table. The above operation method is simple and has a high conveying and stacking efficiency, but the following problems still exist in the actual production process.

[0005] 1) When the marble slab is turned over by the turning table, it will slide down along the table naturally. The sliding speed is uncontrollable, which may easily cause a strong collision impact between the edge of the marble slab and the supporting structure. Although the marble slab has high hardness, it is relatively brittle. Therefore, the natural sliding impact may cause the marble slab to have internal cracks and edge breakage risks.

[0006] 2) The marble slabs are not placed in a completely standardized manner during transportation, and they may also shift left and right during the process of flipping and sliding, making the stacked marble basically non-aligned. Therefore, manual alignment is required during batch packaging, which is more laborious. In addition, the stacked marble slabs are close to each other, and the polished surface of the marble slabs may be scratched during the alignment process, affecting the decorativeness of the marble slabs. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a conveying device for processing marble slabs, which is used to solve the problems mentioned in the above background technology.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme to achieve it: a conveying device for processing marble slabs, including a horizontally arranged guide rail base, along the guiding direction of the guide rail base are sequentially distributed a flip unloading machine for flipping and unloading the marble slabs and a stacking table for guiding the marble slabs to be stacked and stacked after unloading; the flip unloading machine includes a conveying base movably arranged along the guide rail base, a flipping table is installed on the conveying base, a bracket conveying table is fixedly installed on the flipping table, and the bracket conveying table is provided with a bracket for supporting and placing the marble slabs.

[0009] When the turning table turns over, the conveying table drives the bracket conveying table and the bracket to turn synchronously with the stacking table; the turning table is equipped with a turning positioning mechanism, which includes a lower support baffle plate linearly driven in a direction perpendicular to the turning axis of the turning table and two side clamping assemblies installed in linkage with the lower support baffle plate; the two side clamping assemblies are horizontally symmetrically distributed.

[0010] During the turning process of the turning table, when the lower supporting baffle plate approaches the marble slab, the marble slab slides and is placed on the lower supporting baffle plate, and simultaneously drives the two side clamping assemblies, so that the marble slab is positioned and clamped between the two side clamping assemblies.

[0011] The stacking table includes a stacking table and a stacking frame slidably arranged along the guide rail base; when the conveying base moves to the nearest position toward the stacking table and the turning table turns from a horizontal state to a vertical state, the lower support baffle moves downward, the two side clamping assemblies release the clamping, and the marble slab falls on the stacking table and leans obliquely against the stacking frame.

[0012] Preferably, the turning table includes a turning frame hinged on the conveying base; the lower support baffle is slidably installed on the turning frame, and two support blocks are arranged on the lower support baffle; when the conveying base moves toward the coding table to the nearest position and the turning table is turned from a horizontal state to a vertical state, the coding table is located between the two support blocks.

[0013] Preferably, the side clamp assembly includes a sliding beam horizontally slidably mounted on the flip frame and a guide beam fixed on the bracket conveying platform, and a connecting rod is hinged between the sliding beam and the lower supporting baffle; a plurality of inclined groove guide blocks are provided on the guide beam, and a side clamp is obliquely slidably mounted on each inclined groove guide block, and the side clamp is vertically slidably mounted on the sliding beam; when the two sliding beams in the two side clamp assemblies slide relatively close to each other, the two side clamps in relative positions in the two side clamp assemblies approach each other synchronously and move upward synchronously.

[0014] Preferably, the stacking support surface of the stacking table is an inclined surface, which gradually tilts upward along the guide direction of the guide rail base in the direction approaching the flip unloader; the leaning surface on the stacking frame for leaning the marble slabs is arranged perpendicular to the inclined surface of the stacking table.

[0015] Preferably, the side clamping member comprises a sliding block slidably mounted on the inclined groove guide block, a guide rod slidably matched with the sliding beam is fixed to the bottom end of the sliding block, and a side clamping guide roller is vertically rotatably mounted on the top end of the sliding block.

[0016] Preferably, the bracket conveying platform includes two guide beams fixed on the turning frame, and a plurality of conveying rollers for jointly conveying the bracket are horizontally rotatably mounted on the two guide beams, and the axial direction of the conveying rollers is perpendicularly arranged relative to the axial direction of the turning axis of the turning frame; a plurality of guide wheels distributed along the length direction are vertically rotatably mounted on the top of the guide beam, and the bracket is conveyed and moved under the guidance of the two rows of guide wheels; the guide beam is fixed between the two guide beams.

[0017] Preferably, the flip frame includes two cross beams and a plurality of longitudinal beams fixedly connected between the two cross beams; the two guide beams are fixed one by one at the top ends of the two cross beams; at least one guide column is fixed on the lower support baffle plate and is horizontally slidably installed on one of the cross beams that is closer to the stacking frame; the sliding beam is slidably installed between the two cross beams.

Compared with the existing related equipment, a flipping positioning mechanism is installed on the flipping structure. Before flipping, the marble slab can be automatically centered and positioned, which is convenient for direct alignment after the marble is stacked and stacked, saving manpower for adjustment and reducing the risk of scratching the surface of the marble slab. During the flipping process, the marble slab can be guided to flip and slide down, so that the flipping and sliding speed of the marble slab is controllable, which not only improves the stability and safety of the flipping and falling of the marble slab, but also avoids the collision and impact of the marble slab when the existing equipment flips and slides, and eliminates the risk of collision and breakage of the edge of the marble slab and cracks inside the marble slab as much as possible; in summary, the conveying device provided by the present invention not only meets the basic conveying, flipping, stacking and stacking of marble slabs, but also improves the stability and safety of the operation during conveying, unloading and stacking, and also protects the integrity of the structure and surface of the marble slab to avoid unnecessary damage.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figure 1 As shown, a conveying device for processing marble slabs includes a guide rail base 1 fixed to the ground by bolts, and the guide rail base 1 includes two horizontally parallel guide rails 11; along the direction of the guide rails 11, there are sequentially distributed a flip unloader for flipping and unloading the marble slabs 8 and a stacking platform 7 for guiding the marble slabs 8 after unloading to be stacked and stacked; the conveying device provided by the present invention is installed in the marble slab 8 production line, and is mainly used for flipping and unloading the marble slabs 8 that have been processed, and vertical stacking and stacking are realized, so that the stacked marble slabs 8 can be transferred and transported to other processing and production workshops for subsequent processing, or the finished marble slabs 8 can be sorted and packaged. In this embodiment, it is specifically installed in the marble slab 8 back-gluing production line to unload and stack the marble slabs 8 that have completed the back-gluing processing. It should be noted that the conveying device provided by the present invention mainly realizes the function of flipping, unloading and stacking the slabs, so it is not only limited to the use in the marble slab 8 back-gluing production line, but also suitable for other applicable production and conveying occasions.

[0037] like Figure 2 , Figure 3 and Figure 4As shown, the tipping unloader includes a conveying base 2, which includes two movable bottom beams 21 slidably mounted on two guide rails 11 in a one-to-one correspondence, and a bottom frame 22 horizontally welded between the top ends of the two movable bottom beams 21; the movable bottom beam 21 is equipped with two rollers that roll along the guide rails 11, and the conveying base 2 serves as a mobile structure for the tipping unloader to tip over and unload to the stacking platform 7. A hydraulic cylinder can be fixedly installed on the ground to drive the conveying base 2 to move along the guide rails 11. A tipping platform 3 is installed on the conveying base 2, and the tipping platform 3 includes a tipping frame 31 and two tipping hydraulic cylinders 32 for driving the tipping frame 31 to tip. The tipping frame 31 includes two cross beams 311 and two longitudinal beams 312 horizontally welded between the two cross beams 311. The two cross beams 311 are vertically arranged relative to the guide rails 11, and the bottom end of the cross beam 311 closer to the stacking platform 7 is hinged on the bottom frame 22, and the bottom ends of the two tipping hydraulic cylinders 32 are hinged on the bottom frame 22. The two tipping hydraulic cylinders 32 The output ends are hinged on the two longitudinal beams 312 one by one. The two flip hydraulic cylinders 32 can drive the flip frame 31 to flip in the direction biased towards the stacking platform 7, and the flipping range of the flip frame 31 is from the horizontal state to the vertical state. In order to achieve buffering and enhance support, a buffer joist 221 is fixed to the bottom frame 22 by bolts. The top of the buffer joist 221 is covered with a rubber layer. When the flip frame 31 is in a horizontal state, the cross beam 311 far away from the stacking platform 7 falls on the buffer joist 221.

[0038] During transportation, the marble slabs 8 are placed in Figure 6 As shown in the figure, the rectangular bracket 5 made of profiles is used for welding, and the marble slab 8 is indirectly transported by transferring the conveying bracket 5 in the entire conveying system of the production line; Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a carriage conveying platform 4 for conveying the carriage 5 is fixedly mounted on the turning frame 31; the carriage conveying platform 4 includes two guide beams 41 welded one by one to the top ends of the two cross beams 311, and a plurality of conveying rollers 42 for jointly conveying the carriage 5 are horizontally rotatably mounted on the two guide beams 41, and the axial direction of the conveying rollers 42 is perpendicularly arranged relative to the axial direction of the turning axis of the turning frame 31; a plurality of guide wheels 411 evenly distributed along the length direction are vertically rotatably mounted on the top ends of the guide beams 41, and the carriage 5 is conveyed and moved by the conveying rollers 42 under the guidance of the two rows of guide wheels 411. In addition, when the turning frame 31 turns over, the carriage conveying platform 4 turns over synchronously therewith, and a row of guide wheels 411 on the guide beams 41 that are closer to the stacking platform 7 can prevent the carriage 5 from sliding off with the turning. It should be supplemented that in order to prevent the carriage 5 from falling off at the guide wheels 411 during the turning process, in the present invention, the surrounding frames of the carriage 5 are channel steels, and the guide wheels 411 are embedded in the grooves of the frames of the carriage 5 during guided conveying. The carriage conveyor platform 4 drives the carriage 5 to move through the conveying roller 42, which is the prior art, and its conveying drive method will not be described in detail here; the direction in which the carriage conveyor platform 4 drives the carriage 5 to convey is perpendicular to the direction in which the guide rail 11 guides the unloading conveying. The conveying device provided by the present invention is assembled in the entire conveying system of the marble slab 8 production line, so the carriage conveyor platform 4 should also be docked with the conveying part of the entire conveying system used to convey the carriage 5. When the conveying base 2 is farthest from the stacking platform 7, the carriage conveyor platform 4 is just in the docking state, so that the carriage 5 can be circulated and conveyed in the entire conveying system. During actual transportation, the carriage 5 adopts intermittent relay transportation, and the bracket 5 is basically in a predetermined position when it pauses on the carriage conveyor platform 4 each time it is relayed.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, a flipping and positioning mechanism 6 is installed on the flipping platform 3, and the flipping and positioning mechanism 6 includes a driving hydraulic cylinder 61, a lower supporting baffle 62, and two side clamping assemblies 63 installed in linkage with the lower supporting baffle 62; the driving hydraulic cylinder 61 is horizontally fixed on the crossbeam 311 close to the stacking platform 7 by bolts, and the output direction of the driving hydraulic cylinder 61 is arranged parallel to the longitudinal beam 312, and the lower supporting baffle 62 is fixed to the output end of the driving hydraulic cylinder 61 by bolts, and the lower supporting baffle 62 is located at the periphery of the flipping frame 31, and the lower supporting baffle 62 is fixed by screws There are two guide pillars 623 slidably mounted on the crossbeam 311, and the two guide pillars 623 are horizontally symmetrically distributed on both sides of the driving hydraulic cylinder 61. The lower supporting baffle plate 62 is provided with two supporting blocks 621 for supporting the marble slab 8 after flipping and sliding down, and the supporting surface of the supporting block 621 is covered with a rubber layer for buffering. In addition, in order to ensure the safety and stability of the flipping process, a front baffle bar 622 is welded on the supporting surface of the supporting block 621, and the front baffle bar 622 is used to block the front plate surface of the marble slab 8 after flipping.

[0040] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the two side clamp assemblies 63 are horizontally symmetrically distributed; the side clamp assembly 63 includes a sliding beam 631 horizontally slidably installed between the two cross beams 311 and a guide beam 633 welded between the two guide beams 41, a connecting rod 632 is hinged between the sliding beam 631 and the lower support baffle 62, and the connecting rod 632 passes through the cross beam 311; two inclined groove guide blocks 6331 are arranged on the guide beam 633, and the inclined groove guide blocks 6331 are provided with a sliding groove in an inclined state, and each inclined groove guide block 6331 is correspondingly equipped with a side clamp 634, and the side clamp 634 includes a slider 6341 slidably installed in the sliding groove on the inclined groove guide block 6331, and the bottom end of the slider 6341 is vertically welded with a guide rod 6342 that slidably cooperates with the sliding beam 631, and the top of the slider 6341 The side clamping guide roller 6343 is installed vertically at the end; when the driving hydraulic cylinder 61 drives the lower supporting baffle 62 to slide close to it, the lower supporting baffle 62 drives the two sliding beams 631 to slide relatively close to each other along the two cross beams 311 through the two connecting rods 632, and the side clamping member 634 moves synchronously with the sliding beam 631, and the slider 6341 is under the dual guidance of the guide rod 6342 and the inclined groove guide block 6331, so that the two side clamping members 634 in relative positions in the two side clamping assemblies 63 are synchronously approached and moved upward synchronously; it should be noted here that when the side clamping member 634 is in the lowest position as a whole, the side clamping guide roller 6343 is located below the bracket 5, and when the side clamping member 634 is in the highest position as a whole, the side clamping guide roller 6343 passes through the bracket 5 upward.

[0041] like Figure 1 , Figure 8 and Fig.11As shown, the stacking platform 7 includes a stacking platform 71 centrally arranged between two guide rails 11 and a stacking frame 72 slidably arranged along the guide rail base 1; the stacking platform 71 is arranged away from the center relative to the two support plates 621, and the stacking support surface of the stacking platform 71 is an inclined surface, which gradually tilts upward along the guide direction of the guide rail base 1 toward the direction of the flip unloader; the inclined surface on the stacking frame 72 for the marble slab 8 to lean against is vertically arranged with the inclined surface of the stacking platform 71 (it can be seen that the inclined surface of the stacking frame 72 is used for the marble slab 8 to lean against, and the inclined surface of the stacking platform 71 is vertically arranged (it can be seen that the inclined surface of the stacking platform 71 is vertically arranged with the inclined surface of the stacking platform 71). Fig.11 The stacking frame 72 has rollers installed at the bottom end thereof, and the stacking frame 72 rolls along the two guide rails 11 through the rollers. In order for the marble slabs 8 to be laid out and stacked along the inclined surface of the stacking platform 7 during the stacking process, the stacking frame 72 can be moved and adjusted along the guide rail base 1. Specifically, the stacking frame 72 can be automatically slid along the guide rail 11 through a motor screw or other driving structure.

[0042] In actual operation, after the marble slab 8 is processed with adhesive backing, it is transported to the bracket conveyor platform 4 by the conveying system. Then, the driving hydraulic cylinder 61 is started, and the lower supporting baffle 62 is driven to move closer to the driving hydraulic cylinder 61. The lower supporting baffle 62 indirectly drives the two side clamping assemblies 63, so that the marble slab 8 is horizontally clamped between the four side clamping guide rollers 6343, and the side clamping centering of the marble slab 8 is pre-positioned to complete the position correction. This state is as shown in FIG. Fig. 9 Then, the conveying base 2 moves along the guide rail 11 toward the material stacking table 71 to the nearest position, and then the flip hydraulic cylinder 32 drives the flip frame 31 to flip to a vertical state, and the bracket 5 is synchronously flipped to a vertical state, and the frame groove of the bracket 5 is stuck on the lower row of guide wheels 411. Fig.10 As can be seen, during the flipping process of the bracket 5, the marble slab 8 flips synchronously with the bracket 5. Since the two sides of the marble slab 8 are clamped between the two groups of side clamping guide rollers 6343, the contact friction is increased, and the side clamping guide rollers 6343 themselves are rotatable. Therefore, under the action of the sliding force under its own gravity, the marble slab 8 slides down at a low speed along the two groups of side clamping guide rollers 6343 along the surface of the bracket 5 until it slowly falls on the two support plates 621. Through the pre-clamping of the two groups of side clamping guide rollers 6343, not only the position of the marble slab 8 is adjusted to the center, which is convenient for direct alignment of the marble after stacking, saving manpower for adjustment, and reducing the risk of scratching the surface of the marble slab 8, but also the flipping and sliding speed of the marble slab 8 is controllable, which improves the stability and safety of the flipping and falling of the marble slab 8, and avoids the collision and impact on the marble slab 8 during flipping and sliding, and eliminates the risk of edge collision and rupture of the marble slab 8 and internal cracks as much as possible.

[0043] When the marble slab 8 is flipped to a vertical state, at this time, the marble slab 8 is located above the inclined surface of the stacking table 71. Subsequently, the driving hydraulic cylinder 61 is started again to drive the lower support baffle 62 to move downward, so that the supporting surface of the lower support baffle 62 drops relative to the inclined surface of the stacking table 71 and avoids it. At the same time, the two sets of side clamping guide rollers 6343 are separated from the side walls of the marble slab 8, and the marble slab 8 falls on the inclined surface of the stacking table 71, slides down slightly along the inclined surface, and then leans against the inclined surface of the stacking frame 72.

[0044] Then, the flip frame 31 flips back to a horizontal state, and the conveying base 2 moves back to the direction away from the stacking table 71. After unloading, the bracket 5 continues to be conveyed forward along the conveying direction in the conveying system. When the next bracket 5 with the marble slabs 8 moves to the bracket conveying table 4, the flip unloader is started again and the above operation is repeated, so that the marble slabs 8 are placed on the stacking table 71 one by one and stacked on the stacking frame 72. It should be noted here that in the process of stacking one by one, the stacking frame 72 gradually moves away from the flip unloader to free up a larger inclined supporting area of ​​the stacking table 71.

[0045] When the number of marble slabs 8 stacked on the stacking frame 72 reaches a predetermined number, the plurality of marble slabs 8 stacked can be removed as a whole.

[0046] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
