Description

Technical Field

[0001] This utility model belongs to the field of stone unloading, specifically relating to an integrated device for stone unloading, conveying, and moving. Background Technology

[0002] In the production of natural stone slabs, the rough stones, which have been processed into relatively square shapes, are cut into slabs. The bottom ends of these slabs are still connected before they are transported to the unloading area for unloading.

[0003] For example, Chinese patent application CN 120246668 A discloses an automatic stone unloading machine, which relates to the field of stone unloading. It includes a lifting unit, a lateral shifting unit, an unloading unit, a suction unit, and a moving unit. The lifting unit includes a base frame, two sets of vertical drive components, and four vertical arms. The four vertical arms are welded and fixed to the top of the base frame in pairs, one in front and one behind. Two horizontal supports are welded and fixed between the left and right vertical arms. The vertical drive components are installed between the upper and lower horizontal supports. This utility model, through the parallel layout of N sets of independent breaking mechanisms, separates the pneumatic pick and the suction cup handling functions. While the suction unit and the moving unit work together to handle stone slabs, the pneumatic pick can break other stone slabs, truly realizing parallel operation of the unloading process, greatly shortening the overall unloading time, and significantly improving the unloading efficiency.

[0004] This unloading machine is the second-generation automatic stone unloading machine made by the inventor. During subsequent use, the inventor discovered that after the pneumatic pick breaks the slab, it is necessary to wait for the suction unit to move into place, suction the slab, and move it away from the work area before the next slab can be processed.

[0005] During this process, it is impossible to achieve a seamless connection between unloading and conveying the stone, and the problem of low unloading efficiency still exists.

[0006] Therefore, we propose an integrated stone unloading, conveying, and handling device to solve the above problems. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves seamless connection between stone unloading and conveying by integrating a breaking mechanism, a unloading unit, and an adaptive telescopic roller conveying unit: After the pneumatic hammer completes the breaking operation, the breaking mechanism separates the stone slab from the rubble base. The receiving plate actively receives the stone slab, and by controlling the synchronous contraction of two receiving cylinders, it is smoothly lowered to the top of multiple flexible transmission components. Subsequently, each flexible transmission component operates synchronously under the drive of the synchronous shaft, timely conveying the stone slab to the adaptive telescopic roller conveying unit. Multiple rollers rotate synchronously to smoothly convey the stone slab, effectively avoiding the operation interruption caused by waiting for handling in traditional equipment, and significantly improving the unloading efficiency and automation level.

[0020] 2. This utility model, by setting two receiving plates, allows the stone slab to be actively received after separation from the rubble base. By controlling the synchronous contraction of two receiving cylinders, the stone slab is smoothly lowered to the top of multiple flexible transmission components, facilitating the subsequent conveying mechanism to transport the stone slab. This effectively avoids the impact caused by the free tilting of the stone slab. Even if the stone slab itself has cracks, the probability of breakage can be significantly reduced, greatly improving the yield and reducing resource waste.

[0021] 3. By setting up multiple sets of conveying mechanisms and driving multiple drive wheels through the same synchronous shaft, this utility model can ensure the synchronicity of the operation of multiple flexible transmission components, so as to smoothly convey the stone slabs being received, improve the automation level of stone production and processing and increase the overall production capacity. In addition, the multiple sets of conveying mechanisms can be adapted to the receiving and conveying of stone slabs of different widths, meet diverse production needs, and improve the versatility and applicability of the device.

[0022] 4. This utility model controls the synchronous contraction of two lifting cylinders to make the common beam and multiple insert plates descend smoothly, so that the insert plates are inserted into the gaps of the stone slabs. The side plates, common beam and multiple insert plates are driven to move slightly to the left synchronously by the lateral drive module, so as to separate the stone slabs from the rubble base, thereby reducing the workload of workers.

[0023] 5. This utility model, by setting multi-level slots and pluggable travel stops on the side plate, can flexibly adjust the lifting stroke of the common beam according to the thickness of the stone slab, and adapt to the unloading operation of stone slabs of different specifications.

[0024] 6. This utility model, by assembling two sets of traction mechanisms on corresponding partitions, allows for the traction of single-row and double-row scissor-type telescopic frames along the track, enabling adaptive telescopic adjustment. This allows for synchronous adjustment of the conveying front end position as the pneumatic pick moves forward, ensuring that the stone slabs can be promptly received by the conveying device after unloading. This significantly improves the coordination between unloading and conveying processes and greatly enhances operational continuity.

[0025] 7. This utility model forms a multi-point, high-load-bearing support system by installing rotatable transverse pulleys at both ends of the roller shaft and slidingly engaging the transverse pulleys with the track. This avoids problems such as frame deformation and roller shaft offset during the conveying process, and significantly improves the structural stability and operational reliability of the device when carrying heavy stone slabs.

[0026] 8. By setting up two sets of material feeding beams, one set of stone slabs can be unloaded while the other set is loaded, allowing for alternating operations, which significantly reduces equipment idle time and improves overall work cycle and production efficiency.

[0027] 9. The pallet handling unit of this utility model integrates a walking mechanism, a lifting mechanism and a suction mechanism. It can automatically grab the unloaded stone slabs at the end of the adaptive telescopic roller conveyor unit and transport them to the designated pallet or stacking area without human intervention, which greatly reduces the labor intensity of workers.

[0028] 10. This utility model uses multi-point distributed sponge suction cups combined with vacuum negative pressure adsorption, which can closely adhere to the surface of the stone slab and form an effective sealed cavity. Even when facing slabs with uneven surfaces or micro-cracks, it can achieve firm adsorption. Attached Figure Description

A spring 8517 is sleeved on the guide rod 8516. The two ends of the spring 8517 are respectively connected to the support plate 8518 and the tail end of the pneumatic pick 8515. Relying on the elastic force of the spring 8517, the pneumatic pick 8515 is supported. The pick provides continuous and stable downward pressure, ensuring contact between the pick and the bottom of the stone slab. Through the elastic suspension system formed by the elastic connecting components and the connecting beam 854, the pick of each pneumatic pick 8515 can adaptively adjust according to the actual condition of the stone slab surface, ensuring full contact between the pick and the bottom of the stone slab. Thus, under the action of spring 2 859 and spring 3 8517, the pneumatic pick 8515 maintains a stable working state, achieving uniform and efficient breaking of the connection between the stone slab and the base 79. This not only improves the efficiency of the breaking operation but also ensures the quality of the finished stone product.

The two single-row sprockets 836 are connected by a chain 835. By starting the geared motor 834, the synchronous shaft 831 is driven to rotate under the transmission action of the single-row sprockets 836 and the chain 835.

[0052] Multiple conveying mechanisms are respectively set on multiple partitions 802. Multiple conveying mechanisms can adapt to the receiving and conveying of stone slabs of different widths, meet diverse production needs, and improve the versatility and applicability of the device. The conveying mechanism includes a drive wheel 824, a flexible transmission component 822, and at least one wheel frame 821. In this embodiment, there are two wheel frames 821. The drive wheel 824 is mounted on a synchronous shaft 831. Multiple drive wheels 824 are driven by the same synchronous shaft 831, which can ensure the synchronicity of the operation of multiple flexible transmission components 822, and smoothly convey the received stone slabs, thereby improving the automation level of stone production and processing and increasing the overall production capacity.

[0053] One wheel frame 821 is located below the drive wheel 824, and another wheel frame 821 is located on the right side of the partition 802. The wheel frame 821 is mounted on the partition 802. A wheel axle is rotatably installed inside the wheel frame 821, and a driven wheel 825 is fitted on the wheel axle.

[0054] The receiving plate mechanism includes at least two receiving plates 812 and a corresponding number of driving components. A rotating sleeve 817 is welded and fixed to the lower end of the receiving plate 812. Two mounting seats 811 are welded and fixed between the connecting base plate 801 and the connecting top plate 804 on the right side. Two fixing sleeves 816 are welded and fixed to the side of the mounting seat 811 corresponding to the rotating sleeve 817. The rotating sleeve 817 and the two fixing sleeves 816 are connected by a pin, so that the receiving plate 812 can rotate.

[0055] The driving component is a receiving cylinder 814, which is located between two partitions 802. One end of the receiving cylinder 814 is hinged to a U-shaped seat 815 via a pin, and the U-shaped seat 815 is welded and fixed to the upper surface of the left connecting base plate 801. The other end of the receiving cylinder 814 is hinged to a lug plate 813 via a pin, and the lug plate 813 is welded and fixed to the upper end of the receiving plate 812. By controlling multiple pneumatic picks 8515 to work synchronously, after the pneumatic picks 8515 break the connecting part and the stone slab separates from the rubble base 79, the receiving plate 812 actively receives the stone slab. By controlling the synchronous retraction of the two receiving cylinders 814, the stone slab is smoothly lowered to the top of the flexible transmission component 822, so that the subsequent conveying mechanism can transport the stone slab. This effectively avoids the impact caused by the free tilting of the stone slab. Even if the stone slab itself has cracks, it can significantly reduce the probability of breakage, greatly improve the yield, and reduce resource waste.

[0056] The adaptive telescopic roller conveyor unit 6 includes a drive assembly, a single-row scissor telescopic frame, a double-row scissor telescopic frame, and two sets of traction mechanisms. Multiple roller shafts 642 are arranged between the two sets of tracks 33.

[0057] The single-row scissor lift telescopic frame includes multiple sets of scissor arm units arranged sequentially in the left-right direction.

[0059] The two rows of fork arm units are connected by the same central hinge hole 632, and the two lower hinge holes are connected by the same lower pin 636. The upper hinge hole 2 of the fork arm unit is equipped with a bearing 2.

[0060] The two ends of the roller 642 are respectively protruded by bearing one on a single-row scissor-type telescopic frame and bearing two on a double-row scissor-type telescopic frame. Under the action of bearing one and bearing two, the roller 642 can rotate stably.

[0061] The roller 642 at the end of the conveyor is fitted with bearing housings 65 at both ends. The two bearing housings 65 are installed on two sets of tracks 33 respectively, forming a fixed support point for telescopic adjustment.

[0062] The two ends of the subsequent roller 642 are respectively provided with sliding parts, which are transverse pulleys 67. The inner hole of the transverse pulley 67 is equipped with a bearing 3, which is fitted on the end of the roller 642. The transverse pulley 67 can slide within the track 33 without affecting the rotation of the roller 642. Each roller 642 is fitted with a roller 641 for supporting the stone slabs. By installing rotatable transverse pulleys 67 at both ends of the roller 642, and the transverse pulleys 67 slidingly engaging with the track 33, a multi-point, high-load-bearing support system is formed, thereby avoiding problems such as frame deformation and roller 642 offset during the conveying process, and significantly improving the structural stability and operational reliability of the device when carrying heavy stone slabs.

[0063] Two adjacent rollers 642 are connected by a set of synchronous transmission mechanisms. The synchronous transmission mechanism includes double-row sprockets 635 corresponding to the number of rollers 642. The double-row sprockets 635 are mounted on the rollers 642 and located between the two rows of telescopic mechanisms. A double-row sprocket 633 is provided below each of the two adjacent double-row sprockets 635. A bearing 4 is installed in the inner hole of the double-row sprocket 633. The bearing 4 is mounted in the middle section of the central pin 632. Under the action of the bearing 4, the double-row sprocket 633 rotates stably, ensuring stable power transmission.

[0064] The adjacent double-row sprocket 633 and double-row sprocket 635 are connected by a chain 634, which enables multiple roller shafts 642 to rotate synchronously, and multiple rollers 641 to rotate synchronously to smoothly transport the stone slabs.

The single-row sprocket 663 and the double-row sprocket 635 at the end of the conveying process are connected by a chain 662, which causes the roller 642 at the end of the conveying process to rotate. Then, under the transmission cooperation of multiple sets of synchronous transmission mechanisms, all rollers 642 rotate synchronously.

[0066] The traction mechanism includes a limiting guide component 611 and a wheel-shaped sliding component 612 that slides in cooperation with the limiting guide component 611. One side of the wheel-shaped sliding component 612 consists of two bearings 5 ​​mounted on the first end pin 622, and the other side of the wheel-shaped sliding component 612 consists of a grooved wheel mounted on the first end middle pin 632. The guide component corresponding to the two bearings 5 ​​is made of square steel, and a slot is opened on one side of the square steel corresponding to the bearing 5, so that the hinge arm 621 can extend into the slot, and the two bearings 5 ​​can slide up and down in the square steel. The guide component corresponding to the grooved wheel is made of a round rod and two steel plates. The round rod is welded and fixed between the two steel plates, and the two steel plates are welded and fixed to the traction plate 613. The grooved wheel is set between the traction plate 613 and the round rod, and can slide up and down along the round rod.

[0067] The traction plate 613 is welded and fixed to the side of the limiting guide component 611 away from the wheel-shaped sliding component 612, and the two traction plates 613 are respectively welded and fixed to the left end of the corresponding partition plate 802. The single-row scissor-type telescopic frame and the double-row scissor-type telescopic frame can be pulled by two sets of traction mechanisms to adaptively extend and retract along the track 33. The position of the conveying front end can be adjusted synchronously with the forward movement of the working position of the pneumatic pick 8515, thereby ensuring that the stone slabs can be received by the conveying device in time after being unloaded. This greatly improves the coordination between the unloading and conveying processes, not only reducing the intensity of manual operation, but also significantly improving the continuity of operation.

[0068] The pallet conveyor unit is located on the left side of the adaptive telescopic roller conveyor unit. It includes a walking mechanism, a lifting mechanism, a suction mechanism, and two parallel walking top rails 1101. One end of the walking top rail 1101 is fixedly connected to the top frame 23, and a support column 1102 is welded and fixed to its bottom.

[0069] The traveling mechanism includes a traveling beam 1106, a rotating shaft 1115, and two traveling end beams 1117. The two traveling end beams 1117 are respectively mounted on two traveling top rails 1101. The traveling beam 1106 is welded and fixed between the two traveling end beams 1117. The rotating shaft 1115 is located below the traveling beam 1106, and multiple bearing seats 1116 are fitted on its outer side. The bearing seats 1116 are fixedly mounted on the bottom of the traveling beam 1106. The two ends of the rotating shaft 1115 are respectively connected to the traveling gears of the two traveling end beams 1117. A reduction motor 3 is mounted on one of the traveling end beams 1117. The output shaft of the reduction motor 3 is connected to the end of the rotating shaft 1115.

[0070] The lifting mechanism includes a hollow shaft reduction motor 1113, a rotating shaft 1112, two lifting arms 1104, and two mounting arms 1107. The mounting arms 1107 are fixedly installed on the left side of the traveling beam 1106. A reinforcing plate 1110 is welded and fixed between the right side of the mounting arms 1107 and the top of the traveling beam 1106. Multiple fixed guide blocks 1118 are fixedly installed on the left side of the mounting arms 1107 from top to bottom. A rack 1108 and a long slide bar 1119 are fixedly installed on the left and right sides of the lifting arms 1104, respectively.

The hollow shaft geared motor 2 1113 drives rotating shaft 1 1112 and the two gears 2 1109 to rotate. Gears 2 1109 mesh with rack 2 1108 to make the two lifting arms 1104 move up and down synchronously.

[0072] The suction plate mechanism is located at the bottom of the lifting mechanism. The suction plate mechanism includes two square tubes 1121 and multiple sponge suction cups 1120. Two rectangular plates 1105 are welded and fixed between the two square tubes 1121. The upper rectangular plate 1105 is welded and fixed to the bottom of the two lifting arms 1104. Multiple sponge suction cups 1120 are arranged sequentially below the rectangular plates 1105 from front to back. Multiple connectors 1122 connect the sponge suction cups 1120 and the lifting arms 1104. The air passage interface of the sponge suction cups 1120 is connected to the vacuum pump through a vacuum pipeline. By making close contact between the sponge suction cups 1120 and the upper surface of the stone slab, the edge of the sponge suction cups 1120 and the surface of the stone slab form a sealed cavity. By starting the vacuum pump, the interior of the sponge suction cups 1120 is extracted to form a negative pressure, which firmly adsorbs the stone slab.

[0073] In practical use, the integrated stone unloading, conveying and moving device of this utility model first places the whole stone slab with the rough stone base on the top of the two material feeding beams 97 in the same group by a forklift. Then, the hollow shaft reduction motor 98 is started to drive the corresponding axle 94 and the corresponding single-rim wheel 95 to rotate, thereby making the loading platform 93 move forward or backward on the ground rail 92 and move the stone slab to the right side of the jackhammer 8515. Start the lateral drive module to drive the side plate 101 and the unloading unit 8 to move to the right, so that the pick of the pneumatic hammer 8515 approaches the stone slab. Then control the synchronous extension of the four hydraulic rods 41 to lower the lifting beam 31 and the unloading unit as a whole, so that the pick of the pneumatic hammer 8515 corresponds to the bottom of the stone slab. Controlling the synchronous extension and retraction of two adjusting cylinders 852 pushes the connecting beam 854 to slide in the movable groove 805 of the partition 802. Through the rotational cooperation of the bushing 857 and the support shaft 855, the working angle of all the breaking mechanisms is changed synchronously. Then, multiple sets of pneumatic picks 8515 are started to efficiently break the connection between the stone slab and the base 79. After multiple sets of pneumatic picks 8515 break the connecting parts, the synchronous contraction of the two lifting cylinders 78 is controlled to make the common beam 71 and multiple insert plates 73 descend smoothly, so that the insert plates 73 are inserted into the gaps of the stone slabs. By restarting the lateral drive module, the lateral drive module drives the side plate 101 and the entire plate breaking mechanism 7 to make a small lateral movement to the left along the track 33, separating the stone slabs from the rubble base. Two receiving plates 812 actively receive the stone slabs and control two receiving cylinders 814 to retract synchronously, so that they are smoothly lowered to the top of the flexible transmission component 822. The second reduction motor 834 is started, and under the transmission action of the second single-row sprocket 836 and the third chain 835, the synchronous shaft 831 is driven to rotate, so that multiple drive wheels 824 rotate synchronously and multiple flexible transmission components 822 operate synchronously to smoothly transport the received stone slabs. Afterwards, multiple flexible transmission components 822 transport the stone slabs to the adaptive telescopic roller conveying unit 6, turn on the reduction motor 661, drive the end roller shaft 642 to rotate, and drive all rollers 641 to rotate synchronously through the synchronous transmission mechanism to form a continuous conveying surface. The synchronously rotating rollers 41 smoothly transport the stone slabs to the end of the conveying process. At this time, the control walking mechanism drives the lifting mechanism and suction plate mechanism to move above the stone slab. The hollow shaft reduction motor 1113 drives the rotating shaft 1112 and the two gears 1109 to rotate. The gears 1109 mesh with the transmission rack 1108, so that the two lifting arms 1104 and the suction plate mechanism move downward synchronously, so that the sponge suction cup 1120 is in close contact with the upper surface of the stone slab. The edge of the sponge suction cup 1120 forms a sealed cavity with the surface of the stone slab. By starting the vacuum pump, the inside of the sponge suction cup 1120 is extracted to form a negative pressure, which firmly adsorbs the stone slab. The lifting mechanism drives the suction plate mechanism and the stone slab to move upward, so that the stone slab is separated from the roller 41. At the same time, the traveling mechanism drives the lifting mechanism and the suction plate mechanism to move above the tray. Then the lifting mechanism drives the suction plate mechanism and the stone slab to move downward, placing the stone slab on the tray. As the unloading unit 8 moves forward, two sets of traction mechanisms pull the single-row scissor-type telescopic frame and the double-row scissor-type telescopic frame, which adaptively extend and adjust along the track 33 to ensure that the stone slabs can be received by the conveying device in a timely manner after being unloaded.

The sliding component is a connecting sleeve 77 or a slider 8513, and the guide component is a guide rod 74 or a guide rail. When the guide component is a guide rod 74, the upper and lower ends of the guide rod 74 are also fixed with fixing blocks 75, and the fixing blocks 75 are fixedly installed on the side plate 101.

[0076] Example 4: Based on Example 1, such as Figure 3 As shown, the side plate 101 has multiple slots 72 arranged from top to bottom. At least one slot 72 is provided with a pluggable travel stop 76. The travel stop 76 is located above or below the common beam 71. By providing multiple slots 72 and pluggable travel stops 76 on the side plate 101, the lifting stroke of the common beam 71 can be flexibly adjusted according to the thickness of the stone slab, which can adapt to the unloading operation of stone slabs of different specifications.

[0077] Example 5: Based on Example 1, such as Figure 9 As shown, it also includes a guide block 841, a slide rail 843, and at least one proximity sensor switch 846. The guide block 841 is welded and fixed to the upper surface of the right-side connecting base plate 801. The slide rail 843 is slidably engaged with the guide block 841, and a positioning head 845 is fixedly connected to its right end. A spring 842 is sleeved on the outside of the slide rail 843. The two ends of the spring 842 are respectively connected to the guide block 841 and the positioning head 845. Relying on the elastic force of the spring 842, when the positioning head 845 is not in contact with the stone slab, the positioning head 845 continues to remain in the initial extended state on the right side of the device.

[0078] A sensor plate 844 for cooperating with a proximity sensor switch 846 is welded and fixed to the upper surface of the slide rail 843. The proximity sensor switch 846 is installed on the right-side connecting top plate 804 and is located above the sensor plate 844. When the positioning head 845 contacts the stone slab, the positioning head 845, slide rail 843 and sensor plate 844 will move to the left due to the obstruction of the stone slab. When the sensor plate 844 moves to the left, the proximity sensor switch 846 will trigger a signal to determine that the chisel of the pneumatic pick 8515 has contacted the stone slab and reached the working position.

[0079] Example 6 Based on Example 1, such as Figure 15 As shown, the material feeding beam 97 is made of square steel, and a groove is provided at the top left position. An adjustable push plate 99 that can slide along the groove is provided inside the groove.

[0080] A hydraulic cylinder 910 is installed in the internal cavity of the feeding beam 97. The piston rod of the hydraulic cylinder 910 is fixedly connected to the adjusting push plate 99. When the forklift places the stone slab on the two feeding beams 97, if the stone slab tilts, the adjusting push plate 99 can be driven to move laterally by controlling the extension and retraction of the hydraulic cylinder 910 on the corresponding side, thereby pushing the stone slab to correct its position.
