Description

Technical Field

[0001] This utility model relates to the technical field of stone processing equipment, specifically to the working device of a stone unloading machine. Background Technology

[0002] In the processing of natural stone slabs, a whole rubble needs to be cut into multiple slabs. These slabs are usually connected at the bottom and then transported to the unloading station for separation. The traditional unloading process is as follows: first, a stone slab breaking mechanism breaks the connecting part at the bottom of the slab, and then stone slab suction cups pick up the separated slabs and transport them to the subsequent conveyor line. The breaking mechanism and the suction cup device are usually integrated on the same rotating frame, with the suction cups serving as the connecting point for the stone slabs.

[0003] However, the existing technology has obvious drawbacks: First, the stone slab suction cup needs to complete multiple processes such as adsorption, transfer and release, and the system process is complex and has a low fault tolerance rate; Second, the suction cup components are prone to wear and tear due to long-term contact with the edges of the stone, and their reliability is insufficient. Once a failure occurs, it will cause the whole machine to stop, which will seriously affect production efficiency.

[0004] Based on the above, this utility model proposes a working device for a stone unloading machine, which can effectively solve the above problems. Utility Model Content

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present utility model. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present utility model.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0030] like Figures 1 to 6 As shown, the working device of the stone unloading machine includes a slab placement structure 2 and a cutting workpiece 3. The slab placement structure 2 includes a receiving structure 21 and a flipping structure. The receiving structure 21 is connected to the flipping structure and is provided with a flipping shaft 22. The flipping structure is used to drive the receiving structure 21 to flip around the flipping shaft 22 to receive the vertical stone slab 6 in the processing position. The cutting workpiece 3 is used to process the connection between the lower end of the vertical stone slab 6 in the processing position and the original stone base plate 7 from the front into a weak connection that is easy to break.

[0031] In this embodiment, the flipping structure is a flipping cylinder connected to the receiving structure. The flipping cylinder works to drive the receiving structure 21 to rotate around the flipping shaft 22.

[0032] A feeding mechanism 5 is provided on the side of the plate-laying structure 2 away from the processing position. The feeding mechanism 5 is a material-retrieving robot 51, and its end is provided with an adjustable-angle suction plate structure 52 for picking up the unloaded stone plate.

[0033] It also includes a breaking mechanism 4, which is used to break the connection between the vertical stone slab 6 on the processing position and its lower end, thereby causing the vertical stone slab 6 to tilt toward the receiving structure 21.

[0034] Both the plate-laying structure 2 and the breaking mechanism 4 are mounted on the support frame 1.

[0035] In one embodiment, the breaking structure 4 includes a working component 41, which is movable and can be raised and lowered. The working component 41 is capable of relative movement with the vertical stone slab 6 located at the processing position, causing the connection at the lower end of the vertical stone slab 6 to break, thereby causing the vertical stone slab 6 to tilt toward the receiving structure 21. The working component 41 is located above the vertical stone slab 6.

[0036] In this embodiment, the movable working component 41 is an insert plate that can abut against the vertical stone slab 6 in the processing position. Both ends of the insert plate are connected to the front-to-back displacement mechanism 42, and are further connected to the up-down displacement mechanism 43 through the front-to-back displacement mechanism 42, so as to realize the three-dimensional movement of the insert plate among multiple stone slabs.

[0037] The forward and backward displacement mechanism 42 includes a first movable cylinder 421, a first slide rail 422, a first connecting plate 423, and a first slider 424 disposed on the working component 41. The first slide rail 422 is disposed on the first connecting plate 423, and the first connecting plate 423 is connected to the output end of the first movable cylinder 421. The working component 41 is slidably connected to the first slide rail 422 through the first slider 424.

[0038] The up-down displacement mechanism 43 includes an up-down moving cylinder including a second moving cylinder 431, a second slide rail 432, a second connecting plate 433, and a second slider 434 disposed on the working component 41. The second slide rail 432 is disposed on the second connecting plate 433, and the second connecting plate 433 is connected to the output end of the second moving cylinder 431. The front-back displacement mechanism 42 is slidably connected to the second slide rail 432 through the second slider 434.

[0039] The support frame 1 is equipped with two limit sensors 46, which are used to limit the travel of the insert plate in the front and back and up and down, respectively, to ensure that the insert plate can be accurately aligned with the stone slab in the processing position.

[0040] In another embodiment, the breaking mechanism 4 includes a liftable working component 41 and a driving device 44. The working component is positioned above the vertical stone slab 6 and abuts against the vertical stone slab 6 located at the processing position. The stone to be processed is mounted on the driving device 44. The stone to be processed consists of multiple vertical stone slabs connected at their bottom. The driving device 44 drives the vertical stone slab 6 to move, causing relative movement between the working component 41 and the vertical stone slab 6 located at the processing position, thereby causing the connecting part at the lower end of the vertical stone slab 6 to break, and the vertical stone slab 6 tilts towards the receiving structure 21. In this embodiment, the driving device 44 is a trolley structure.

[0041] The receiving structure 21 includes a receiving plate 211 or a plurality of receiving rollers 212 arranged in a row.

[0042] The flipping shaft 22 is located on one side of the receiving structure 21. This side is parallel or nearly parallel to the bottom cutting line of the vertical stone slab 6 and is the side closest to the processing position.

[0043] The cutting workpiece 3 is disposed on the receiving structure 21, and the cutting workpiece 3 can slide along the direction of the flipping axis 22 on the receiving structure.

[0044] The cutting workpiece 3 is positioned on the receiving structure 21 closer to the processing position than the receiving structure 21.

[0045] The cutting workpiece 3 includes several air hammers 32 or cutting machines 31 arranged in a row, and the air hammers 32 or cutting machines 31 are configured to be inclined downwards.

[0046] In one embodiment, the cutting workpiece 3 consists of two cutting machines 31 connected by an adjustable-depth cylinder 38 to adjust the cutting depth to accommodate joints of different thicknesses. When the joint is thick, the two cutting machines 31 can be adjusted to cut at different depths to ensure proper cutting. The two cutting machines 31 are mounted on a mounting plate 33, which is equipped with movable rollers 34. When the cutting workpiece 3 is mounted on a receiving plate 211, the rollers form a rolling connection with the side of the receiving plate 211.

[0047] In another embodiment, the cutting workpiece 3 consists of two air hammers 32, which are also mounted on the mounting plate 33.

[0048] The receiving structure 21 is provided with a roller guide rail 36 and a drive mechanism 37. The drive mechanism 37 is connected to the roller guide rail 36, and the cutting workpiece 3 is mounted on the roller guide rail 36. The bottom of the mounting plate 33 is provided with a slider 35 connected to the guide rail. The drive mechanism 37 drives the roller guide rail 36 to move, thereby causing the mounting plate 33 and the cutting workpiece 3 on it to move along the direction of the flipping axis 22 on the receiving structure 21.

[0049] The following section, in conjunction with the working process of the stone unloading machine, further illustrates the structure and technical effects of this utility model.

[0050] After the upright stone slab 6 is pushed to the processing position by the drive device 44, the cutting workpiece 3 (such as a cutting machine 31 or a pneumatic hammer 32) begins to cut or knock the bottom of the upright stone slab 6 at the processing position, so that the connection between the lower end of the upright stone slab 6 at the processing position and the original stone base slab 7 is processed from the front into a weak connection that is easy to break. Then, the insert plate moves to the rear and upper part of the upright stone slab 6 at the processing position under the drive of the front and rear displacement mechanism 42, and then moves downward under the action of the up and down displacement mechanism 43 until the insert plate moves downward to the gap between the upright stone slab 6 at the processing position and the upright stone slab behind it.

[0051] At this point, the vertical stone slab 6 can be displaced relative to its lower end in two ways, thus achieving breakage:

[0052] Method 1: The entire stone to be processed is moved in the rear direction by the drive device 44. Since the upper part of the vertical stone slab 6 is restricted by the insert plate and cannot move, the connection part at the lower end of the vertical stone slab 6 is broken.

[0053] Method 2: The insert plate is driven forward by the front and rear displacement mechanism 42. Since the insert plate abuts against the upper part of the vertical stone slab 6, the forward movement of the insert plate will apply a forward thrust to the vertical stone slab 6, causing the connecting part at the lower end of the vertical stone slab 6 to break.

[0054] After the stone slab breaks, it tilts forward and rests on the receiving structure 21. At this time, the tilting cylinder in the tilting structure 22 is activated, driving the receiving structure 21 to rotate around the tilting axis 22. When the receiving structure 21 rotates to form a 90° angle with the horizontal plane, the broken stone slab is reliably supported on its surface; subsequently, the receiving structure 21 continues to rotate to an inclined state forming a 10° angle with the horizontal plane, facilitating the slab-picking action of the material handling robot 51.

[0055] At this time, the material handling robot 51 receives the signal, moves down, and uses the suction plate structure 52 or the fork plate to remove the stone slab, which then enters the subsequent sorting or classification process.

[0056] While the stone slab is being removed, the cutting workpiece 3 (such as the cutting machine 31 or the air hammer 32) begins to cut or knock the bottom of the next upright stone slab 6. The operation direction can start from the left or right, forming a continuous operation process, thereby improving the overall unloading efficiency and automation level.

[0057] Based on the description and drawings of this utility model, those skilled in the art can easily manufacture or use the working device of the stone unloading machine of this utility model, and can produce the positive effects described in this utility model.
