Description

Technical Field

[0001] This invention relates to the field of loading machines, specifically a movable double-layer belt conveyor and a loading machine having the double-layer belt conveyor. Background Technology

[0002] Currently, automatic loading machines in industries such as cement, grain, and chemicals all use belt conveyors to transport bagged materials. The belt conveyor is connected to the gripping roller conveyor and the robotic gripper, and moves back and forth along the guide rail direction (hereinafter referred to as the horizontal direction) following the gripping roller conveyor.

[0003] The belt conveyor needs to catch the material being transported from the discharge port during the reciprocating motion to ensure that the material is not lost throughout the entire process.

[0004] Current automatic loading machines all use single-layer belt conveyors. Although this structure is simple, it cannot meet the stroke requirements when there is insufficient horizontal installation space.

[0005] If an additional belt conveyor is added on top of a single-layer belt conveyor to extend the material receiving distance, the gripper or operating device connected to the lower belt conveyor will interfere with the upper belt conveyor when the lower belt conveyor retracts horizontally.

[0006] A search revealed that existing patent 201310535230.3, "A Loading Machine for Bagged Materials on a Cargo Platform," does not explicitly disclose any technical insights that solve the aforementioned technical problems.

[0007] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the design of existing belt conveyors or loading machines. Summary of the Invention

[0054] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0055] A movable double-layer conveyor belt includes a lower conveyor belt 6 and an upper conveyor belt 7; the upper conveyor belt 7 and the lower conveyor belt 6 are stacked together; the upper conveyor belt 7 is connected to the lower conveyor belt 6 through a motion mechanism; the upper conveyor belt 7 can move along the lower conveyor belt 6; the present invention, through the cooperative use of the upper conveyor belt 7 and the lower conveyor belt 6, can save lane installation space and realize the function of increasing the loading stroke of the loading machine under the condition of limited lane space.

[0056] Specifically, the double-layer belt conveyor disclosed in this invention mainly includes a lower belt conveyor 6 and an upper belt conveyor 7. Both the lower belt conveyor 6 and the upper belt conveyor 7 can transport materials, and the upper belt conveyor 7 and the lower belt conveyor 6 can be used in conjunction to achieve simultaneous material transport and replenishment. In addition, as a further optimization, this invention requires the upper belt conveyor 7 and the lower belt conveyor 6 to be stacked. The upper belt conveyor 7 is connected to the lower belt conveyor 6 through a motion mechanism. The upper belt conveyor 7 can move along the lower belt conveyor 6. With this arrangement, the relative positions of the lower belt conveyor 6 and the upper belt conveyor 7 can be changed as needed during subsequent use, thereby realizing the material transport and transfer length of the entire double-layer belt conveyor, thus adapting to different lane installation spaces.

[0057] Furthermore, the motion mechanism described in this invention includes a guide rail 61 disposed on the lower belt conveyor 6 and a motion part 62 disposed on the upper belt conveyor 7; the upper belt conveyor 7 can move along the guide rail 61 on the lower belt conveyor 6 via the motion part 62; the basic function of the motion mechanism in this invention is to facilitate the connection between the upper belt conveyor 7 and the lower belt conveyor 6, and the motion mechanism also plays a good guiding role in subsequent use.

[0058] In actual arrangement, the guide rail 61 extends along the length of the lower belt conveyor 6; during subsequent operation, the upper belt conveyor 7 can be guided along the length of the lower belt conveyor 6.

[0059] In this invention, the moving part 62 can be a slider structure or a sliding roller structure, the main purpose is to enable it to cooperate with the guide rail 61.

[0060] Furthermore, in this invention, the lower belt conveyor 6 includes a lower frame 67, on which a conveyor belt mechanism 601 is provided; the lower frame 67 is the main structure of the lower belt conveyor 6, and the conveyor belt mechanism 601 is provided on the lower frame 67 to facilitate the operation of materials on it; at the same time, the lower frame 67 is provided with a lower roller mechanism; the setting of the lower roller mechanism facilitates the installation of the lower belt conveyor 6 on the steel platform 1 and subsequent movement guidance.

[0061] In actual design, the present invention requires that the lower roller mechanism include multiple sets of supporting roller mechanisms 6901; adjacent supporting roller mechanisms 6901 are arranged along the length of the lower frame 67; this arrangement also requires that adjacent supporting roller mechanisms 6901 be spaced apart. Based on this arrangement, the lower belt conveyor 6 disclosed in the present invention has multiple supports, ensuring the stability of the lower belt conveyor 6 arranged on the steel platform 1.

[0062] Meanwhile, in this invention, each set of supporting roller mechanisms 6901 includes two individual roller mechanisms 69 arranged at intervals and opposite to each other; the individual roller mechanisms 69 in each set of supporting roller mechanisms 6901 are distributed on both sides of the lower frame 67; at the same time, each of the individual roller mechanisms 69 in this invention includes a lower support frame 691, and the lower support frame 691 is provided with a lower roller 693 at the end away from the lower frame 67; the lower support frame 691 has a longitudinal lifting function, and the setting of the lower roller 693 facilitates the subsequent operation of the lower belt conveyor 6.

[0063] During actual installation and connection, the side plate of the lower roller 693 is provided with a limiting flange, that is, the edge of the lower roller 693 has a protrusion. This setting makes the lower roller 693 equivalent to a train wheel structure. This setting makes it convenient to be snapped onto the ground rail on the steel platform 1 during subsequent use.

[0064] Meanwhile, in this invention, a lower support frame 691 is provided with a lower recess 692, and the lower roller 693 is arranged at the end of the lower recess 692. One end of the lower roller 693 is connected to the inner wall of the lower recess 692, and the other end is connected to the lower support frame 691 through the lower end panel 694. This arrangement makes the lower roller 693 essentially embedded in the lower support frame 691. At the same time, the lower end panel 694 facilitates the replacement of the lower roller 693 in the future. In addition, the above installation requires that the lower roller 693 can rotate normally.

[0065] In addition, the upper belt conveyor 7 described in this invention includes an upper frame 71; the upper frame 71 is the main structure of the upper belt conveyor 7. At the same time, the upper frame 71 is also provided with a conveyor belt mechanism 601; the conveyor belt mechanism 601 is also used to transport and transfer materials on the upper belt conveyor 7. Similarly, the upper frame 71 is provided with an upper support roller mechanism; the upper support roller mechanism is mainly to facilitate the subsequent operation of the upper belt conveyor 7.

[0066] Specifically, the upper support roller mechanism in this invention includes a front roller mechanism 74 and a rear roller mechanism 75; the front roller mechanism 74 and the rear roller mechanism 75 are distributed at both ends of the upper frame 71, thereby enabling the arrangement and placement of the upper belt conveyor 7.

[0067] In addition, in this invention, the upper belt conveyor 7 is connected to the guide rail 61 via a front roller mechanism 74; this arrangement facilitates the connection between the upper belt conveyor 7 and the lower belt conveyor 6, while the upper belt conveyor 7 is connected to the lower belt conveyor 6 or the steel platform 1 via a rear roller mechanism 75.

[0068] In actual installation, the upper belt conveyor 7 can be directly placed on the steel platform 1 or directly placed on the lower belt conveyor 6. The specific placement position can be selected according to the needs. In actual use, the tail of the upper belt conveyor 7 is generally placed on the steel platform 1 to ensure the coordinated operation of the upper belt conveyor 7 and the lower belt conveyor 6 in subsequent use, and to ensure the control of the overall structure.

[0069] In this invention, the front roller mechanism 74 includes a front mounting bracket 741 mounted on the upper frame 71. The front mounting bracket 741 is connected to the guide rail 61 via a moving part 62. The moving part 62 includes a sliding wheel 621, which is embedded in the inner groove of the guide rail 61. The sliding wheel 621 is connected to the front mounting bracket 741 via a side plate 622. In actual placement, the front mounting bracket 741 is positioned directly above the guide rail 61, providing excellent protection. Even if the sliding wheel 621 derails, the front mounting bracket 741 still provides good support and protection.

[0070] Meanwhile, the conveyor belt mechanism 601 in this invention includes a conveyor belt body 65 disposed on a lower frame 67 or an upper frame 71. The conveyor belt body 65 is connected to a drive mechanism, which includes a drive roller 66 and a driven roller 63 distributed at both ends of the conveyor belt body 65. The drive roller 66 is connected to a drive motor 607. In subsequent use, the drive motor 607 drives the drive roller 66 to rotate, and the drive roller 66 rubs against the conveyor belt body 65, thereby ensuring the normal operation of the conveyor belt mechanism 601.

[0071] Furthermore, the conveyor belt mechanism 601 in this invention also includes idler roller assemblies disposed on the lower frame 67 or the upper frame 71. The idler roller assembly includes an upper idler roller assembly 64 and a lower idler roller assembly 641, which are attached to the inner side of the conveyor belt body 65. The present invention ensures support for the conveyor belt body 65 and optimizes the load-bearing capacity of the conveyor belt mechanism 601 by setting the idler roller assembly. At the same time, the idler roller assembly of the present invention also has the effect of significantly increasing the strength of the conveyor belt mechanism 601. In subsequent use, the upper and lower belt conveyors can store materials, realize the accumulation function, and ensure that the conveyor line can be reset normally after a fault stop without the need to deal with the materials on the conveyor line.

[0072] In this invention, the conveyor belt body has a ring-shaped structure. The upper idler assembly 64 and the lower idler assembly 641 disclosed above are distributed inside the conveyor belt body. The upper idler assembly 64 supports and limits the conveyor belt body above it, and the lower idler assembly limits the position of the conveyor belt body below it. Based on the cooperative use of the above components, large deformation of the conveyor belt body can be avoided.

[0073] Furthermore, in this invention, both the upper idler assembly 64 and the lower idler assembly 641 include multiple individual idlers 6410. Each individual idler 6410 is connected to the corresponding lower frame 67 or upper frame 71 via an idler snap-fit ​​part. The idler snap-fit ​​part includes an idler snap-fit ​​plate 6401, and the idler snap-fit ​​plate 6401 is provided with a snap-fit ​​groove 6402. The mutual cooperation of the idler snap-fit ​​plate 6401 and the snap-fit ​​groove 6402 facilitates the connection between the individual idler 6410 and the corresponding lower frame 67 or upper frame 71.

[0074] Meanwhile, in this invention, each individual idler roller 6410 is provided with a rotating shaft 6403 at its end, and the rotating shaft 6403 is provided with a snap-fit ​​groove at its end; the rotating shaft 6403 is connected to the snap-fit ​​groove 6402 through the snap-fit ​​groove. This arrangement facilitates the connection between the individual idler roller 6410 and the idler roller snap-fit ​​plate 6401; the cooperation between the snap-fit ​​groove and the snap-fit ​​groove 6402 plays a good limiting role, which can prevent the rotating shaft 6403 from rotating or moving relative to the idler roller snap-fit ​​plate 6401.

[0075] Furthermore, the double-layer belt conveyor described in this invention also includes a baffle mechanism; in this invention, the baffle mechanism plays a good lateral limiting role, which can guide the running trajectory of the material when the conveyor belt mechanism 601 is transporting materials, and prevent the material from falling off the side of the conveyor belt mechanism 601.

[0076] Specifically, the baffle mechanism in this invention includes two spaced-apart side baffles 6-7, each side baffle 6-7 being connected to the corresponding lower frame 67 or upper frame 71 via a lateral support 6101; in actual arrangement, the side baffles 6-7 can be arranged above the conveyor belt 65 to avoid interference between the side baffles 6-7 and the operation of the conveyor belt 65.

[0077] Furthermore, in this invention, each side baffle 6-7 includes multiple individual baffles 6-71, with adjacent individual baffles 6-71 arranged in a mating arrangement; this arrangement facilitates the assembly of each side baffle 6-7 piece, and in actual use, side baffle 6-7 structures of the required length can be assembled as needed; thus improving the applicability of this invention.

[0078] The vertical cross-section of the individual baffle 6-71 is []. This design ensures the structural strength of the individual baffle 6-71. At the same time, a bridging end plate 6-72 is provided at the end of each individual baffle 6-71, and the bridging end plate 6-72 is provided with fastening through holes. When adjacent individual baffles 6-71 are joined together, the bridging end plate 6-72 not only increases the contact area between the two individual baffles 6-71, but also facilitates subsequent connection by passing bolts through the two bridging end plates 6-72 to achieve a fixed connection between the two individual baffles 6-71.

[0079] Furthermore, in this invention, the end of the baffle mechanism is also connected to a chute mechanism. The chute mechanism facilitates the transfer of material from the upper belt conveyor 7 to the lower belt conveyor 6. In this invention, the chute mechanism includes a chute plate disposed at the end of the upper frame. The upper end of the chute plate is not higher than the upper end face of the upper conveyor belt, that is, the chute plate is located below the upper end face of the conveyor belt in the upper belt conveyor, which facilitates the smooth transfer of material.

[0080] Meanwhile, the chute plate 76 of the present invention extends from the upper frame 71 to the lower frame 67, and the chute plate 76 is arranged at an angle.

[0081] In addition, in this invention, the chute plate 76 is required to have end side baffles 6-8 on opposite sides; each end side baffle 6-8 is connected to the end plate of one side baffle 6-7 in the baffle mechanism; the end side baffles 6-8 play a good role in lateral limiting at the end, preventing materials from falling from the side of the chute plate 76.

[0082] Meanwhile, in this invention, each individual baffle 6-71 and the end side baffle 6-8 are connected to the corresponding upper frame 71 or lower frame 67 via a lateral bracket 6101; the lateral bracket 6101 is connected to the corresponding upper frame 71 or lower frame 67 via a bracket connecting part 610, the bracket connecting part 610 including a side frame support 6102, the side frame support 6102 having a U-shaped groove 6103, the lateral bracket 6101 having a screw structure, and two fastening nuts 6104 on the lateral bracket 6101, the fastening nuts 6104 being distributed on both sides of the side frame support 6102 of the lateral bracket 6101; in use, the two fastening nuts 6104 moves along the axial direction on the lateral support 6101, and two fastening nuts 6104 are fastened to both sides of the lateral support, thereby limiting the position of each individual baffle 6-71 and the end side baffle 6-8. In subsequent use, by controlling the position of the two fastening nuts 6104 on the lateral support 6101, the lateral relative position of each individual baffle 6-71 and the end side baffle 6-8 can be adjusted, thereby controlling the gap between adjacent relative individual baffles 6-71 and relative end side baffles 6-8, making it suitable for the transfer of bags of different sizes. The essential purpose is to control the transfer direction of the bags and prevent the bags from turning over, being misaligned, or being wrapped horizontally.

[0083] Furthermore, in this invention, a limiting buffer mechanism 68 is provided on the lower frame 67 of the lower belt conveyor 6. The setting of the limiting buffer mechanism makes the collision position of the upper belt conveyor 7 and the lower belt conveyor 6 smooth, and avoids rigid collision between the upper belt conveyor 7 and the lower belt conveyor 6.

[0084] Meanwhile, in this invention, the limiting buffer mechanism 68 includes two individual buffer mechanisms. Each individual buffer mechanism includes a buffer support frame 681 set on the lower frame 67. The setting of the buffer support frame 681 facilitates the arrangement of the buffer 682 and the limiting post 683. In this invention, the buffer support frame 681 is provided with a limiting post 683 at one end near the guide rail 61. The buffer support frame 681 is provided with a buffer 682. The buffer 682 can be a buffer post, or a telescopic rod, buffer spring, or other structure, mainly to serve as an energy-absorbing buffer during impact.

[0085] The buffer 682 disclosed in this invention is arranged laterally. This arrangement is mainly for use in conjunction with the front roller mechanism 74. In specific use, the buffer 682 interacts with the side of the front roller mechanism 74 to achieve the corresponding buffering effect.

[0086] In this invention, the setting of the limiting post 683 is mainly to limit the extreme positions of the upper belt conveyor 7 and the lower belt conveyor 6, so as to avoid the problem of derailment after the upper belt conveyor 7 or the lower belt conveyor 6 reaches the extreme position; in order to better achieve the above arrangement, the limiting post 683 of this invention is required to be arranged at the end of the guide rail 61.

[0087] Furthermore, in this invention, the guide rail 61 is a channel steel structure; the vertical cross section of the guide rail 61 is [shaped]; this arrangement allows the guide rail 61 to have an opening on its side, which facilitates its use with the roller mechanism of the moving part 62. This not only facilitates the connection between the upper belt conveyor 7 and the lower belt conveyor 6, but also limits the longitudinal relative position of the upper belt conveyor 7 and the lower belt conveyor 6.

[0088] Furthermore, the rear roller mechanism 75 in this invention includes a rear rolling bracket 751, on which a traveling wheel 752 is provided; the traveling wheel 752 is connected to an electromagnetic brake 753; by setting the electromagnetic brake 753, the position of the upper belt conveyor 7 can be controlled as needed. When the upper belt conveyor 7 moves, its position can be controlled as needed to avoid the upper belt conveyor 7 from continuously moving due to inertia or other reasons, causing it to collide with adjacent components.

[0089] A loading machine for bagged materials includes a steel platform 1, on which a following gripping roller conveyor 2, a palletizing robot 3, and a double-layer conveyor belt are mounted; the palletizing robot 3 is connected to the lower layer conveyor belt 6 of the double-layer conveyor belt via the following gripping roller conveyor 2; through the coordinated use of the above components, the loading machine can realize the automatic loading operation of vehicles by stacking layers according to the programmed path.

[0090] Furthermore, the loading machine in this invention also includes a control system. The control system includes a detection module connected to the control module, and the control module is connected to an execution module. The detection module mainly functions as an identification unit and sends corresponding signals to the control module based on the identification. The control module receives the signals transmitted from the control module and performs identification and judgment. After identification and judgment, it issues instructions to control the execution module to perform corresponding actions. The execution module executes the corresponding instructions according to the received signals, thereby realizing the corresponding operation. Based on the above-mentioned control system, this invention can realize the automatic operation of the loading machine and reduce the workload of manual intervention.

[0091] In this invention, the detection module may include a position sensor 73 disposed on the lower or upper frame; the execution module may be various motors or conveyor belt mechanisms; and the control module may be a microcontroller or other controller structure.

[0092] The location and number of position sensors can be selected as needed; other sensor structures can also be used.

[0093] The specific implementation method is as follows:

[0094] Example 1:

[0095] The loading machine disclosed in this invention mainly comprises a ground rail, a steel platform 1, a palletizing robot 3, grippers 5, a gripping roller conveyor 2, and a movable double-layer belt conveyor. The steel platform 1 is equipped with the accompanying gripping roller conveyor 2, the palletizing robot 3, and the double-layer belt conveyor. The accompanying gripping roller conveyor 2 and the palletizing robot 3 are existing technologies and will not be described in detail here. In specific use, the palletizing robot 3 is connected to the lower layer belt conveyor 6 of the double-layer belt conveyor via the accompanying gripping roller conveyor 2. The steel platform 1 is equipped with a ground rail, and the double-layer belt conveyor includes a lower layer belt conveyor 6 and an upper layer belt conveyor 7. The upper layer belt conveyor 7 and the lower layer belt conveyor 6 are stacked together. The upper layer belt conveyor 7 is connected to the lower layer belt conveyor 6 via a motion mechanism. The motion mechanism includes a guide rail 61 disposed on the lower layer belt conveyor 6 and a moving part 62 disposed on the upper layer belt conveyor 7. The upper layer belt conveyor 7 can move along the guide rail 61 on the lower layer belt conveyor 6 via the moving part 62. The guide rail 61 extends along the length of the lower layer belt conveyor 6.

[0096] The palletizing robot 3 is installed on the ground rail slide, which is connected to the gripping roller conveyor and the lower belt conveyor 6. The external shaft motor 4 drives the ground rail slide, gripping roller conveyor, and lower belt conveyor 6 to reciprocate on the guide rail 61 of the steel platform 1.

[0097] The lower belt conveyor 6 is designed with a guide rail 61, and the slider of the upper belt conveyor 7 is connected to the guide rail 61 of the upper belt conveyor 7, so that the upper belt conveyor 7 can slide relative to the lower belt conveyor 6.

[0098] When the lower conveyor belt 6 is a certain distance away from the upper conveyor belt 7, it collides with the upper conveyor belt 7 through the buffer 682. At this time, the upper and lower conveyor belts 6 change from relative motion to relative stationary. The lower conveyor belt 6 drags the upper conveyor belt 7 to move on the guide rail 61, thereby extending the robot's horizontal travel.

[0099] When the lower conveyor belt 6 approaches the upper conveyor belt 7 at a certain distance, it contacts the buffer 682, pushing the upper conveyor belt 7 to move, thus avoiding the problem of collision and interference.

[0100] In addition, the upper belt conveyor 7 is also equipped with a brake roller assembly, which starts and stops synchronously with the external shaft motor 4 to reduce unnecessary horizontal movement of the upper belt conveyor 7.

[0101] Work process:

[0102] When a vehicle is parked in the designated loading area, the system scans and identifies the vehicle's dimensions and loading information to plan the stacking pattern.

[0103] According to the planned path, the external shaft motor 4 drives the slide, gripping roller, and lower belt conveyor 6 to work with the palletizing robot 3 to complete the operation and orderly place the materials into the carriage.

[0104] When the robot's travel distance exceeds the conveying distance of the lower belt conveyor 6, the lower belt limit mechanism comes into contact with the upper belt, causing the upper belt to move together.

[0105] The limiting mechanism is installed on the lower belt conveyor 6 and the fixed steel platform 1 to ensure that the range of motion of the upper belt conveyor 7 is controlled.

[0106] The loading machine stacks the vehicles layer by layer according to the programmed path, and completes the automatic loading of vehicles in a cyclical manner.

[0107] The mobile double-layer belt conveyor for conveying bagged materials saves lane installation space and increases the loading stroke of the loading machine under conditions of limited lane space.

[0108] The double-layer belt conveyor disclosed in this invention: the upper belt conveyor 7 can move relative to the lower belt conveyor 6 in the horizontal direction via a slider or roller;

[0109] The present invention adopts a bidirectional buffer structure: four buffers 682 are provided at both ends of the lower belt conveyor 6, and spring buffers are provided on both sides of the buffer sliding component of the upper belt conveyor 7 connecting slider. The two work together to prevent rigid collision between the upper and lower belt conveyors 6.

[0110] Synchronous start-stop function: The electromagnetic brake 753 in the brake roller assembly is connected to the motor that controls the movement of the operating device. When the operating device stops moving horizontally, the electromagnetic brake 753 is activated, and the upper belt conveyor 7 brakes. When the operating device starts moving horizontally, the electromagnetic brake 753 is deactivated, and the braking is canceled.

[0111] Meanwhile, the present invention, through the guide rail structure, enables the guide rail to have good limiting ability, which can effectively prevent the upper belt conveyor 7 from tipping over and derailing.

[0112] Saves installation space: The double-layer belt mechanism saves lane installation space, and can save 5 meters of lane space under the general 13-meter stroke condition.

[0113] Material storage on the conveyor line, one-button reset in case of failure: The upper and lower belt conveyors can store materials, realizing the accumulation function, ensuring that the conveyor line can be reset normally after a failure stop, without the need to deal with the materials on the conveyor line.

[0114] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
