Description

Technical Field

[0001] The present invention relates to the technical field of loading and conveying equipment for quartz stone production lines, and in particular to a loading and conveying device for a quartz stone slab production line. Background Art

[0002] Quartz stone is usually a new type of stone artificially synthesized from more than 90% quartz crystals plus resin and other trace elements. It is a large-sized slab pressed under certain physical and chemical conditions by a special machine. Quartz stone slabs have good decorative properties, are suitable for public places and outdoor decoration, have beautiful colors, and can be preserved for more than a hundred years. However, quartz stone slabs face many challenges during handling and loading. When the area of a single slab exceeds 0.25 m², according to the operating specifications, it generally needs to be carried and stacked upright. These slabs are not only heavy but also have a large area. If carried or loaded only by manual labor, the operation is extremely difficult. Workers need to consume a lot of physical strength and energy, and the slabs are prone to slipping and tipping during handling, which is very likely to cause physical harm to the operators and pose a great safety hazard. Therefore, when loading and transporting quartz stone slabs, mechanical equipment or auxiliary tools such as forklifts and cranes should be preferred to improve work efficiency and ensure personnel safety.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN117022421A, patent name: A self-calibrating transportation device for quartz stone) is as follows: During specific shipment, first, the air cylinder is used to drive the push rod to operate. The push rod pushes the placement plate to move outside the limit frame, facilitating feeding and stacking. Then, several groups of quartz stone slabs with the same area are stacked on the upper end of the placement plate in sequence by a lifting device and located at one of the limit mechanisms. The front and rear ends of the bottom surface of the quartz stone slab at the bottom layer of the stack are respectively pressed against the surfaces of the transmission cylinders on the inner sides of the front and rear groups of limit mechanisms I, thereby raising the bottom of the quartz stone slab group and forcing a gap to remain between the bottom surface of the quartz stone slab and the table surface of the placement plate for subsequent unloading, so as to prevent the bottom layer of quartz stone slabs from completely adhering to the surface of the placement plate and making it difficult to assemble and unload the quartz stone slabs. When unloading, by means of the rolling force of several groups of rollers on the surface of the transmission cylinder, the feeding speed of the quartz stone slab group is accelerated, and the transportation efficiency of the quartz stone slab is improved.

[0004] From the above implementation scheme and the corresponding drawings, it can be seen that although the transportation device has a clever mechanical structure for the assembly and unloading of quartz stone slabs, there are still certain limitations. It lacks relevant mechanisms to vertically stack the quartz stone slabs. During actual transportation, large-sized quartz stone slabs often need to be vertically stacked to ensure transportation safety and space utilization efficiency. Since this device cannot meet this requirement, when encountering such situations, it will bring inconvenience to the operation, increase the extra workload and operation difficulty, and even may affect the smoothness of the entire transportation process. Summary of the Invention

[0005] The present invention overcomes the shortcomings in the prior art and provides a loading and conveying device for a quartz stone slab production line. By setting up a flap mechanism to accurately dock with a receiving frame, it can not only ensure the smooth transfer of quartz stone slabs between different components but also flexibly change the placement direction of the quartz stone slabs. In addition, this structural design enables the quartz stone slabs to require little manual interference during the entire transfer process, effectively reducing the difficulty of manual operation and also greatly reducing the potential risks brought by manual operation.

The rotating fulcrum is used for connecting the lifting frame body, and the support plate is used for supporting the quartz stone plate; A power connection fulcrum is arranged on one side of the upper end of the arch shape of the turning clip close to the rotating fulcrum. The power connection fulcrum is used for connecting the output end of a rotating power component, and the other end of the rotating power component is connected to the lifting frame body; When the first suction cup is in a state of waiting for adsorption, the turning clip is in an upward flipping position, and at this time, the height of its support plate is higher than that of the first suction cup; After the first suction cup sucks up the quartz stone plate, the output rod of the rotating power component outputs to push the turning clip, so that the turning clip rotates around the rotating fulcrum, and thus the support plate is rotated to the lower end face of the quartz stone plate. At this time, all the support plates are located in the same horizontal plane and within the horizontal projection area of the quartz stone plate, so that the support plates can assist in supporting the lower part of the quartz stone plate when the quartz stone plate is sucked up by the first suction cup.

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] like Figures 1 to 15As shown in the figure, a loading and conveying device for a quartz stone slab production line includes a lifting and clamping assembly 4, a second transfer vehicle 6, and a slab display and transfer cabinet 7. In this embodiment, a first track 1 is further provided. The first track 1 is used for slidably connecting a first transfer vehicle 2. A second track 5 is arranged perpendicular to the first track 1. The second track 5 is used for slidably connecting the second transfer vehicle 6. Above the second track 5, a lifting and transfer track 3 is provided. The second track 5 is arranged parallel to the lifting and transfer track 3. A lifting and clamping assembly 4 is slidably connected to the lifting and transfer track 3. Through the reasonable layout of the first track 1, the second track 5, and the lifting and transfer track 3, as well as the coordinated work of the lifting and clamping assembly 4, the first transfer vehicle 2, and the second transfer vehicle 6, the rapid and accurate transfer of quartz stone slabs between different positions is realized, the residence time of materials during transportation is reduced, and the overall operation efficiency of the production line is improved.

[0022] The second transfer vehicle 6 includes a vehicle body 601. A flap mechanism 604 is rotatably connected to the vehicle body 601. The flap mechanism 604 includes a flap base 6041. One side of the flap base 6041 is rotatably connected to a flap plate 6048. A second suction cup 6049 is arranged on the flap plate 6048. During operation, the first transfer vehicle 2 carries a quartz stone slab and moves along the first track 1 to the lower part of the lifting and transfer track 3. The lifting and clamping assembly 4 clamps the quartz stone slab and places it on the second suction cup 6049 of the second transfer vehicle 6. After the second suction cup 6049 sucks the quartz stone slab, the flap plate 6048 rotates relative to the flap base 6041, rotating the quartz stone slab from a horizontal position to a position with an angle greater than ninety degrees with respect to the horizontal plane, preparing for subsequent transfer work. The flap mechanism 604 can rotate the quartz stone slab from a horizontal position to a position with an angle greater than ninety degrees with respect to the horizontal plane. This change in the placement direction can better meet the requirements of subsequent processing or display, increasing the flexibility and adaptability of the production line.

[0023] The slab display and transfer cabinet 7 is located on the side of the second transfer vehicle 6 away from the lifting and clamping assembly 4. The slab display and transfer cabinet 7 includes a transfer main cabinet 701. A number of independent cabinets 703 are slidably connected inside the transfer main cabinet 701. The independent cabinet 703 includes a cabinet frame 7031. A receiving frame 7033 is rotatably connected to the upper part of the cabinet frame 7031 near the upper end. Before receiving the quartz stone slab, the bottom end of the receiving frame 7033 is propped up, so that an angle is formed between the receiving frame 7033 and the independent cabinet 703. During the quartz stone slab transfer operation, first, the receiving frame 7033 that needs to receive the quartz stone slab is moved closer to the flap mechanism 604. The flipping angle of the flap mechanism 604 is accurately set according to the angle formed between the receiving frame 7033 and the independent cabinet 703, ensuring that the position of the flap mechanism 604 after flipping is finally parallel to the receiving frame 7033. Finally, the second suction cup 6049 releases the quartz stone slab, and the quartz stone slab will smoothly fall into the receiving frame 7033.

[0024] This device precisely docks the flap mechanism 604 with the receiving frame 7033, which can not only ensure the smooth transfer of the quartz stone slab between different components but also flexibly change the placement direction of the quartz stone slab. In addition, this structural design enables the quartz stone slab to be transferred without excessive manual interference throughout the process, effectively reducing the difficulty of manual operation and significantly lowering the potential risks associated with manual operation. While improving the working efficiency of the production line, it also makes the production process safer, more stable, and controllable.

[0025] The second transfer vehicle 6 is slidably connected to the second track 5. The second track 5 is composed of two U-shaped single tracks, and the openings of the two U-shaped single tracks face both sides respectively. Under the vehicle body 601, there are a first row of wheels 602 and a second row of wheels 603. The first row of wheels 602 is rotatably connected to the inside of the opening of the U-shaped single track, and the second row of wheels 603 is rotatably connected to the upper side of the U-shaped single track. Since the turning plate 6048 of the second transfer vehicle 6 needs to be flipped relative to the flap base 6041, setting the first row of wheels 602 inside the opening of the U-shaped single track can effectively prevent the second transfer vehicle 6 from tipping over. This design not only enhances the stability of the connection between the second transfer vehicle 6 and the second track 5 but also ensures that the entire system operates more stably and safely during the flipping process of the turning plate 6048.

[0026] The flap base 6041 is rotatably connected to a driving rotating shaft 6042. The driving rotating shaft 6042 is fixedly connected to one end of the first connecting rod 6044. The other end of the first connecting rod 6044 is rotatably connected to the intermediate rotating shaft 6046. The intermediate rotating shaft 6046 is rotatably connected to one end of the second connecting rod 6045. The other end of the second connecting rod 6045 is rotatably connected to the turning plate 6048. The second suction cup 6049 is installed on the side of the turning plate 6048 away from the second connecting rod 6045. One end of the turning plate 6048 is rotatably connected to the flap base 6041. The driving rotating shaft 6042 is connected to a driving motor 60421. The driving motor 60421 drives the driving rotating shaft 6042 to rotate. The rotation of the driving rotating shaft 6042 drives the second connecting rod 6045 to swing. The swing of the second connecting rod 6045 can then push the turning plate 6048 to flip relative to the flap base 6041. Therefore, the quartz stone slab placed flat on the turning plate 6048 can be flipped into a vertical or inclined state. The setting of the second suction cup 6049 provides a reliable fixing effect during the flipping process of the quartz stone slab. It can effectively prevent the quartz stone slab from slipping due to factors such as inertia and vibration during the flipping process, ensuring the safety and integrity of the quartz stone slab during the flipping process and reducing damage and production accidents caused by the slipping of the quartz stone slab.

[0027] On both sides of the flap base 6041, there are flap limit tracks 60411. The transfer coupling shaft 6046 is rotatably connected to one end of the structural connecting rod 6047. The other end of the structural connecting rod 6047 is rotatably connected to the limit sliding shaft 6043. At both ends of the limit sliding shaft 6043, there are sliders 60431, and the sliders 60431 are slidably connected in the flap limit tracks 60411. At one end of the flap limit track 60411 close to the flipping plate 6048, there is a flap spring 60412. The transfer coupling shaft 6046 also swings under the drive of the first connecting rod 6044. Since the transfer coupling shaft 6046 is connected to the structural connecting rod 6047, the swing of the transfer coupling shaft 6046 can also drive the structural connecting rod 6047, thereby driving the slider 60431 to move in the flap limit track 60411. When the flipping plate 6048 flips and tilts towards the sheet display transfer cabinet 7, one end of the slider 60431 abuts against the flap spring 60412, and the flap spring 60412 is gradually compressed, so that when the flipping plate 6048 flips to a set angle, it will not generate stepped vibrations due to the active motor 60421 stopping driving the active rotating shaft 6042, enabling the flipping plate 6048 to be buffered when it stops rotating, thus further ensuring the stability of the quartz stone slab, ensuring that the quartz stone slab can smoothly transition from the flipping plate 6048 to the receiving rack 7033, providing a stable stopping environment for the quartz stone slab, and further guaranteeing the stability of the quartz stone slab.

[0028] The buffering effect of the flipping plate 6048 when it stops rotating enables the quartz stone slab to transition from the flipping plate 6048 to the receiving rack 7033 more smoothly. This helps to improve the success rate of transferring the quartz stone slab between different components, reduce the position deviation or damage of the slab caused by factors such as vibration and impact, and ensure the continuity and stability of the production line.

[0029] In addition, the setting of the flap limit track 60411 also limits the sliding distance of the slider 60431, thereby limiting the flipping angle of the flipping plate 6048, and avoiding the over-flipping of the flipping plate 6048 due to the setting problem of the active motor 60421, which may harm the operator or damage other mechanisms.

[0030] The active motor 60421 drives the active rotating shaft 6042, and then uses the first connecting rod 6044, the transfer coupling shaft 6046, and the second connecting rod 6045 to drive the flipping plate 6048 to flip. This transmission method can accurately control the flipping angle and speed of the flipping plate 6048, realize the stable flipping of the quartz stone slab from the flat state to the vertical or inclined state, and meet the requirements of different production links for the placement angle of the quartz stone slab.

[0031] The lifting and clamping assembly 4 includes a moving main frame 401, the moving main frame 401 is connected to moving pulleys 402, and the moving pulleys 402 are slidably connected to the lifting and transfer track 3; a lifting frame 403 and a lifting power component 404 are slidably connected to the moving main frame 401. In this embodiment, the lifting power component 404 is an electric cylinder or a pneumatic cylinder, and the output end of the lifting power component 404 is connected to the lifting frame 403. The lifting power component 404 drives the lifting frame 403 to move up and down relative to the moving main frame 401. By sliding the moving pulleys 402 on the lifting and transfer track 3, the lifting and clamping assembly 4 can be flexibly moved to a specified position within the track range, facilitating the clamping operation of quartz stone plates at different positions. At the same time, the lifting power component 404 drives the lifting frame 403 to lift and lower, enabling the transfer of quartz stone plates among different mechanisms.

[0032] A first suction cup 405 is provided on the lifting frame 403. The connecting rod of the first suction cup 405 is slidably inserted into the lifting frame 403. A suction cup spring 4051 is provided between the disc body of the first suction cup 405 and the lifting frame 403. The suction cup spring 4051 can play a buffering role, avoiding damage to the quartz stone plate due to excessive impact force, protecting the integrity of the plate, and reducing the defective rate.

[0033] A number of turning clamps 406 are rotatably connected to the lifting frame 403. The number of turning clamps 406 is symmetrically arranged on both sides of the lifting frame 403. The turning clamps 406 are in an arch shape. Two lower end points of the arch shape of the turning clamps 406 are respectively provided with a support plate 4061 and a rotation fulcrum 4063. The rotation fulcrum 4063 is used to connect the lifting frame 403, and the support plate 4061 is used to support the quartz stone plate; On one side of the upper end of the arch shape of the turning clamp 406 close to the rotation fulcrum 4063, a power connection fulcrum 4062 is provided. The power connection fulcrum 4062 is used to connect the output end of the rotation power component 407. In this embodiment, the rotation power component 407 is an electric cylinder or a pneumatic cylinder, and the other end of the rotation power component 407 is connected to the lifting frame 403; when the first suction cup 405 is in a state of waiting to adsorb, the turning clamp 406 is in an upward flipping position, and at this time the height of its support plate 4061 is higher than that of the first suction cup 405; therefore, the existence of the turning clamp 406 does not affect the adsorption of the quartz stone plate by the first suction cup 405.

[0034] After the first suction cup 405 picks up the quartz stone plate, the output rod of the rotating power component 407 outputs, pushing the turning clamp 406, causing the turning clamp 406 to rotate around the rotation fulcrum 4063, so that the support plate 4061 is rotated to the lower end surface of the quartz stone plate. At this time, all the support plates 4061 are in the same horizontal plane and within the horizontal projection area of the quartz stone plate. Therefore, it can be ensured that the support plate 4061 is directly below the quartz stone plate, enabling the support plate 4061 to assist in supporting the lower part of the quartz stone plate when the quartz stone plate is picked up by the first suction cup 405, and ensuring that the support plate 4061 holds the lower end surface of the quartz stone plate. This double clamping method greatly improves the stability and reliability of clamping the quartz stone plate, prevents the plate from falling during handling, reduces the safety risk in the production process, improves the production efficiency. The arched design of the turning clamp 406 and the settings of the rotation fulcrum 4063 and the power connection fulcrum 4062 enable the rotating power component 407 to efficiently drive the turning clamp 406 to rotate, achieving the accurate positioning of the support plate 4061. The symmetrically distributed turning clamps 406 can evenly apply a lifting force to the quartz stone plate, ensuring the balanced force of the plate and further improving the clamping effect. An end stop is provided at the end of the second track 5. When the second transfer vehicle 6 moves to the end stop, it is blocked. A limit locking part 8 is provided near the end stop. The limit locking part 8 includes a locking cylinder 801. After the second transfer vehicle 6 is blocked by the end stop, the output rod of the locking cylinder 801 is pushed out, bringing out the locking block. The end stop and the locking block respectively restrict the two ends of the second transfer vehicle 6 so that it cannot move on the second track 5. The end stop provides a clear stop position for the second transfer vehicle 6, ensuring that the transfer vehicle can accurately dock at a predetermined location, which is beneficial for subsequent precise docking with the plate display transfer cabinet 7, ensuring the smooth transfer of the quartz stone plate, and improving the accuracy and stability of the production process.

[0035] The setting of the limit locking part 8 further enhances the stability of the second transfer vehicle 6 after it stops. The locking cylinder 801 drives the locking block to cooperate with the end stop to restrict the transfer vehicle from both ends, effectively preventing the transfer vehicle from shifting or shaking due to external forces such as vibration and collision, ensuring that the transfer vehicle remains stationary during operations such as transferring the quartz stone plate, guaranteeing the safety and reliability of the operation. The action of the locking cylinder 801 can be linked with the movement of the second transfer vehicle 6 to achieve automated operation. When the transfer vehicle is blocked and stopped, the locking cylinder automatically starts to lock without manual intervention, improving the production efficiency, reducing the labor cost, and at the same time reducing the possibility of human operation errors.

[0036] The bottom of the total transfer cabinet body 701 is connected to the first caster 7013. The first caster 7013 enables the entire cabinet body to move easily, facilitating flexible adjustment of the position and layout of the cabinet body according to the actual situation of the production site and changes in the production process, improving the adaptability of the equipment and the space utilization rate of the production site.

[0037] A transfer slide rail is provided at the upper end of the total transfer cabinet body 701. The independent cabinet body 703 is slidably connected to the transfer slide rail, ensuring smooth sliding of the independent cabinet body 703 within the total transfer cabinet body 701. At the same time, the position of the independent cabinet body 703 within the total transfer cabinet body 701 is restricted, making the independent cabinet bodies 703 arranged in an orderly manner.

[0038] A cabinet door is provided on one side of the total transfer cabinet body 701. The independent cabinet body 703 can only slide out from one side of the cabinet door. A cabinet door limiting cross bar 7014 is provided at the lower end of the cabinet door. Frame bottom limiting blocks 70311 are provided on both sides at the lower end of the cabinet frame 7031. The frame bottom limiting blocks 70311 are connected to the second caster 7035. The frame bottom limiting blocks 70311 on both sides are respectively arranged on both sides of the cabinet door limiting cross bar 7014. When the independent cabinet body 703 is pulled out from the total transfer cabinet body 701, one of the frame bottom limiting blocks 70311 and the second caster 7035 still remain inside the total transfer cabinet body 701; preventing the independent cabinet body 703 from completely detaching from the total transfer cabinet body 701.

[0039] Chain hooks 7011 and handles 7012 are provided on both sides of the total transfer cabinet body 701. The chain hooks 7011 are provided on the side plate of the total transfer cabinet body 701 near the cabinet door. After all the independent cabinet bodies 703 are pushed into the total transfer cabinet body 701, the chain hooks 7011 are used to hang the chain. The chain is used to prevent the independent cabinet body 703 from sliding out of the total transfer cabinet body 701. The setting of the chain hooks 7011 and the chain can effectively prevent the independent cabinet body 703 from accidentally sliding out due to external forces or vibrations and other factors after all the independent cabinet bodies 703 are pushed into the total transfer cabinet body 701, reducing the probability of equipment damage and production accidents and ensuring the normal progress of production.

[0040] An independent handle 7032 is provided on one side of the independent cabinet body 703; facilitating the operator to manually pull out or push the independent cabinet body 703 into the total transfer cabinet body 701.

[0041] The lower end of the cabinet frame 7031 is internally connected to a receiving and supporting power component 7036. In the present embodiment, the receiving and supporting power component 7036 is an electric cylinder. The output end of the receiving and supporting power component 7036 is connected to the receiving frame 7033. The receiving and supporting power component 7036 is used to prop up the lower end of the receiving frame 7033 so that the receiving frame 7033 can be parallel to the flip plate 6048. After the flip plate 6048 places the quartz slab on the receiving frame 7033, the receiving and supporting power component 7036 contracts so that the receiving frame 7033 can be stored in the cabinet frame 7031, so that the independent cabinet body 703 can be smoothly put into the transfer main cabinet body 701. When the quartz slab needs to be taken or displayed, the independent cabinet body 703 only needs to be pulled out from the transfer main cabinet body 701.

[0042] A bottom slot 70331 is provided at the bottom end of the receiving frame 7033, and front locking rod components 7034 are provided on both sides of the receiving frame 7033; The front locking rod component 7034 includes a locking rod moving electric cylinder 70341, which is connected to a locking rod body 70342, and a plurality of adjusting columns 70344 are threadedly connected to the locking rod body 70342, and the ends of the adjusting columns 70344 are rotatably connected to the sponge rod 70343, and one end of the adjusting column 70344 away from the sponge rod 70343 is rotatably connected to an adjusting nut 70345; When the quartz slab is placed on the receiving frame 7033, the locking rod moving electric cylinder 70341 lowers the locking rod body 70342, so that the locking rod body 70342 moves to the side of the quartz slab away from the receiving frame 7033. The locking rod body 70342 is used to block the quartz slab to prevent the quartz slab from falling off the receiving frame 7033, thereby ensuring the stability and safety of the quartz slab during the receiving process. The adjusting column 70344 is used to adjust the distance between the sponge rod 70343 and the surface of the quartz slab. When using it, the distance between the sponge rod 70343 and the surface of the quartz slab can be set in advance according to the thickness of the quartz slab.

[0043] The quartz slab production line of the present invention is precisely docked with the receiving frame 7033 by setting the turning plate mechanism 604, which can not only ensure the smooth transfer of quartz slabs between different components, but also flexibly change the placement direction of quartz slabs. In addition, this structural design enables the quartz slab to be transferred without excessive manual interference throughout the process, effectively reducing the difficulty of manual operation and also greatly reducing the potential risks brought by manual operation. While improving the working efficiency of the production line, it also makes the production process safer, more stable and controllable. The turning plate limit track 60411, the slider 60431 and the turning plate spring 60412 are cooperated to buffer the turning plate 6048 when it stops rotating, ensuring the stability of the quartz slab so that it can smoothly transition to the receiving frame 7033; at the same time, the flipping angle of the turning plate 6048 is restricted to avoid excessive flipping from harming the operator or damaging other mechanisms.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
