Description

Technical Field

[0001] This application relates to the field of material bag transport equipment, and more particularly to a loading device for material bag trucks. Background Technology

[0002] After the materials are produced (such as cement, rice, chemical raw materials, etc.) and pass quality inspection, the material packages need to be transported in an orderly manner into the container of the freight truck (usually by manual labor or robotic arms).

[0003] Taking a 20-foot container as an example, when using horizontal stacking of material bags inside the container, the container can hold 430 material bags to allow space for operators or robotic arms to handle them, and the freight truck does not exceed its maximum load. Therefore, to increase the amount of material bags that the container can hold at one time, a device that can flip the container for loading has been developed. The flipping device flips the container 90° so that the rear door of the container faces upward, so that the robotic arm can transfer the material bags into the container in an orderly manner. At this time, the material bags are vertically arranged inside the container. After loading is completed, the container is flipped again by the flipping device so that the container's locking pins can be locked to the freight truck. It has been verified that the container can hold 480 material bags at this time without exceeding the freight truck's load, which is conducive to its widespread application.

[0004] However, in practical applications, the inventors discovered that, in order to cooperate with the operation of the flipping device, it is preferable to use a robotic arm to transfer the packages into the container (for example, the robotic arm clamps three packages at a time and sends them into the container simultaneously). In order to cooperate with the robotic arm to transfer the packages and improve the space utilization within the container, the spacing between two adjacent packages is particularly important, so that after the robotic arm transfers the packages into the container, it does not need to make secondary adjustments to the package placement along the container. Using a conveyor belt to transport packages cannot meet the needs of the robotic arm to transfer packages, and there is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a loading device for a material packing cart, in order to facilitate the transfer of material packs to a robotic arm after adjusting the spacing between two adjacent material packs.

[0006] To achieve the above objectives, the present application provides a feeding device for a material packaging vehicle, which adopts the following technical solution:

[0007] A loading device for a material packaging vehicle includes a support plate, on which a main conveying mechanism and a shaping conveying module are disposed. The shaping conveying module is connected to the main conveying mechanism. The shaping conveying module includes a conveying lifting mechanism and two sets of conveying mechanisms. The two sets of conveying mechanisms are arranged in the same direction on the support plate. The conveying lifting mechanism is located between the two sets of conveying mechanisms. The conveying lifting mechanism includes a support frame and a conveying component and a lifting component disposed on the support frame. When material bags are placed on the conveying component and the two sets of conveying mechanisms respectively, the lifting component lifts the material bag located on the conveying component, so that the material bag on the lifting component is above the material bags on the two sets of conveying mechanisms and abuts against the material bags located on the conveying mechanisms.

[0008] Preferably, the conveying assembly includes a plurality of first feeding rods rotatably supported on the support frame, wherein the transverse cross-sectional shape of the first feeding rods is polygonal.

[0009] Preferably, the lifting assembly includes a first driving member and a lifting plate. The first driving member is disposed on the support frame, and the lifting plate is connected to the first driving member. The lifting plate is provided with a plurality of lifting legs, and each lifting leg is located between two adjacent first feeding rods.

[0010] Preferably, the lifting assembly further includes a guide rod, which is fixedly connected to the support frame, and a guide hole is provided on the lifting plate, with the guide rod slidingly engaging with the guide hole.

[0011] Preferably, the main conveying mechanism includes a conveying frame and a guide assembly and a guide slide disposed on the conveying frame. The guide slide is connected to the shaping conveying module. The guide assembly includes a guide feeding belt and a guide frame. The guide frame is disposed on the conveying frame and is inclined towards the end closer to the guide slide along the width direction of the conveying frame. The guide feeding belt is rotatably supported on the guide frame.

[0012] Preferably, the outer corners of the first feeding rod are rounded.

[0013] Preferably, a buffer mechanism is provided on the bearing plate located between the conveying mechanism and the guide slide. The buffer mechanism includes a frame, a transmission assembly, a conveyor belt, and a clamping assembly. The transmission assembly includes a driving roller and a driven roller. The driving roller is rotatably supported on the frame. A slotted groove is provided at one end of the frame away from the driving roller. Bearing covers are coaxially fixed at both ends of the driven roller shaft. The bearing covers are fixedly connected to the frame via bolts through the slotted groove. The conveyor belt is sleeved on the driving roller and the driven roller. The clamping assembly includes a clamping plate and an adjusting bolt. The clamping plate is fixedly connected to the bearing cover. The adjusting bolt is threaded through the frame and fixedly connected to the clamping plate.

[0014] Compared with the prior art, the present invention provides a feeding device for a material packaging vehicle, which has the following advantages:

[0015] 1. The main conveying mechanism transports the material package to the shaping and conveying module. When there are material packages on both the conveying component and the two sets of conveying mechanisms, the lifting component drives the material package on the conveying component to be lifted along the support frame. This places the material package on the conveying component above the material packages on the two sets of conveying mechanisms, and the material package on the conveying component abuts against the material packages on the two sets of conveying mechanisms. This achieves the purpose of shaping the three material packages on the conveying component and the two sets of conveying mechanisms, improving the compactness of the arrangement of the three material packages, so that the robotic arm can simultaneously grab the three material packages and place them into the container.

[0016] 2. Compared with a cylindrical first feeding rod, the first feeding rod has a polygonal cross-sectional shape. When the first feeding rod rotates along the support frame and transports the material bag, the circumferential vibration force generated by the rotation of the first feeding rod along the support frame can be used to loosen the material in the material bag, so that the material in the material bag is evenly distributed along the material bag, reducing the probability of uneven material dispersion and uneven surface of the material bag.

[0017] 3. By cooperating with the guide components and guide slides, the purpose of reversing the transport of the material package located on the transport frame is achieved. After the material package is reversed by the guide components, the movement path of the material package is limited by the guide slides, so that the material package can stably reach the shaping and transport module.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a loading device for a material packaging vehicle. (Refer to...) Figure 1 , Figure 2 as well as Figure 3 A loading device for a material packaging vehicle includes a support plate 1, on which a main conveying mechanism 2 and a shaping conveying module 3 are disposed. The shaping conveying module 3 is connected to the main conveying mechanism 2. The shaping conveying module 3 includes a conveying lifting mechanism 31 and two sets of conveying mechanisms 32. The two sets of conveying mechanisms 32 are arranged in the same direction on the support plate 1. The conveying lifting mechanism 31 is located between the two sets of conveying mechanisms 32. The conveying lifting mechanism 31 includes a support frame 33 and a conveying component 311 and a lifting component 312 disposed on the support frame 33. When material bags are placed on the conveying component 311 and the two sets of conveying mechanisms 32 respectively, the lifting component 312 lifts the material bag located on the conveying component 311, so that the material bag on the lifting component 312 is above the material bags on the two sets of conveying mechanisms 32 and abuts against the material bags located on the conveying mechanisms 32.

[0026] Specifically, the main conveying mechanism 2 includes a conveying frame 23, a servo drive module (not shown in the figure), a transmission roller group 25, and a conveyor belt 24. The servo drive module is mounted on the conveying frame 23, the transmission roller group 25 rotates along the length of the conveying frame 23 and is supported on the conveying frame 23, and the conveyor belt 24 is sleeved on the transmission roller group 25. The servo drive module drives the conveyor belt 24 to rotate along the conveying frame 23, thereby achieving the purpose of orderly sending the finished material packages to the shaping and conveying module 3.

[0027] Furthermore, since the components of the two sets of conveying mechanisms 32 and their cooperation with the bearing plate 1 are the same, one set of conveying mechanisms 32 will be described in detail below.

[0028] The conveying mechanism 32 includes several second feeding rods 321 and a gear and rack motor drive module. The gear and rack motor drive module is mounted on the support frame 33. The several second feeding rods 321 are rotatably supported on the support frame 33. The gear and rack motor drive module drives the several second feeding rods 321 to rotate synchronously along the support frame 33.

[0029] Two sets of conveying mechanisms 32 are symmetrically mounted on the mounting brackets on both sides of the conveying component 311 about the conveying component 311.

[0030] Reference Figure 1 The main conveying mechanism 2 also includes a guide assembly 21 and a guide slide 22. The guide slide 22 is connected to the shaping and conveying module 3. The guide assembly 21 includes a guide feeding belt 211 and a guide frame 212. The guide frame 212 is disposed on the conveying frame 23 and the guide frame 212 is inclined towards the end closer to the guide slide 22 along the width direction of the conveying frame 23. The guide feeding belt 211 is rotatably supported on the guide frame 212.

[0031] Specifically, the guide frame 212 is installed at the tail end of the conveyor frame 23 along the rotation direction of the conveyor belt 24, and the guide frame 212 and the end of the conveyor frame 23 near the guide slide 22 have an inclination angle α, and 30°≤α≤45°. This allows the material bag to be forced to change direction along the conveyor belt 24 at the moment it comes into contact with the guide feeding belt 211 when it reaches the guide frame 212 along the conveyor belt 24. This allows the material bag to quickly separate from the conveyor belt 24 and fall onto the guide slide 22, thus achieving the purpose of unloading the material bag along the conveyor frame 23.

[0032] Therefore, by reversing the direction, the material bag conveying is in a curved motion state, which is beneficial to improving the space utilization of the bearing plate 1 and making the overall layout more compact compared to linear conveying.

[0033] Reference Figure 1 , Figure 3 as well as Figure 4A buffer mechanism 4 is provided on the bearing plate 1 located between the conveying mechanism 32 and the guide slide 22. The buffer mechanism 4 includes a frame 41, a transmission assembly 42, a conveyor belt 43, and a clamping assembly 44. The transmission assembly 42 includes a drive roller 421 and a driven roller 422. The drive roller 421 is rotatably supported on the frame 41. A waist-shaped groove 5 is provided at one end of the frame 41 away from the drive roller 421, and waist-shaped grooves 5 are provided at both ends of the frame 41 along the width direction. Bearing covers 6 are coaxially fixed at both ends of the roller shaft of the driven roller 422. The bearing covers 6 are fixedly connected to the frame 41 by bolts through the waist-shaped grooves 5. The conveyor belt 43 is sleeved on the drive roller 421 and the driven roller 422. The clamping assembly 44 includes a clamping plate 441 and an adjusting bolt 442. The clamping plate 441 is fixedly connected to the bearing cover 6, and the adjusting bolt 442 is threaded through the frame 41 and fixedly connected to the clamping plate 441.

[0034] Specifically, the buffer mechanism 4 also includes a buffer belt 45 and a reversing roller assembly 46. A bracket 7 is installed on the bearing plate 1 near the guide slide 22. The buffer belt 45 is rotatably supported on the bracket 7. The two ends of the reversing roller assembly 46 are respectively connected to the buffer belt 45 and the frame 41. After passing through the guide slide 22, the material bag reaches the buffer belt 45. The buffer belt 45 transports the material bag to the reversing roller assembly 46. Then, the reversing roller assembly transports the material bag to the conveyor belt 43, thereby changing the direction of material bag transportation and enabling the material bag to smoothly reach the shaping and conveying module 3.

[0035] Furthermore, when it is necessary to adjust the distance between the drive roller 421 and the driven roller 422, the adjusting bolt 442 can be loosened. At this time, an adjustment gap is formed between the clamping plate 441 and the adjusting bolt 442, so that the bearing cover 6 can support the driven roller 422 to slide along the waist groove 5. After the distance between the drive roller 421 and the driven roller 422 is adjusted, the adjusting bolt 442 is tightened again so that the adjusting bolt 442 abuts against the clamping plate 441, which can again achieve the purpose of limiting the driven roller 422 along the frame 41, so as to adjust the tension of the conveyor belt 43. The operation is simple.

[0036] Reference Figure 2 The conveying component 311 includes several first feeding rods 3111 that are rotatably supported on the support frame 33. The transverse cross-sectional shape of the first feeding rods 3111 is arranged in a diagonal shape.

[0037] Specifically, in this embodiment, the first feeding rod 3111 and the second feeding rod 321 have the same shape and forming method. The first feeding rod 3111 will be described in detail below.

[0038] First, the outer corners of the first feeding rod 3111 are rounded, so that the outer contour of the first feeding rod 3111 is relatively smooth. This reduces the probability that the outer wall of the first feeding rod 3111 will damage the material bag during the rotation of the first feeding rod 3111 along the support frame 33, or that the force exerted by the material bag on the first feeding rod 3111 is too large, causing the first feeding rod 3111 to be unable to rotate smoothly along the support frame 33.

[0039] The outer contour of the first feeding rod 3111 can be pentagonal, hexagonal, etc. In this embodiment, preferably, the outer contour of the first feeding rod 3111 is quadrilateral.

[0040] When the material bag is conveyed to the first feeding rod 3111 by the cooperation of several second feeding rods 321, only the outer edge of the first feeding rod 3111 and the second feeding rod 321 can come into contact with the material bag during the rotation process. This achieves the purpose of breaking up the material in the material bag during the transportation process, so that the material in the material bag can be evenly distributed, thereby making the surface of the material bag relatively flat, so that the robotic arm can pick up the material bag. At the same time, when the material bag is picked up by the robotic arm and placed in the container, the material bag can be stably arranged in the container without the need for secondary adjustment of the material bag.

[0041] Furthermore, refer to Figure 5 The lifting assembly 312 includes a first driving member 3121 and a lifting plate 3122. The first driving member 3121 is mounted on the support frame 33, and the lifting plate 3122 is connected to the first driving member 3121. The lifting plate 3122 is provided with a plurality of lifting legs 8, and each lifting leg 8 is located between two adjacent first feeding rods 3111.

[0042] The first driving component 3121 can be a motor lead screw drive module. In this embodiment, preferably, the first driving component 3121 is a driving cylinder. Two sets of driving cylinders are provided. The two sets of driving cylinders are symmetrically installed on the support frame 33 about the center line of the support frame 33 along the length direction. The piston rod of the driving cylinder is fixedly connected to the support frame 33.

[0043] Therefore, when the piston rod of the drive cylinder moves, the drive lifting plate 3122 carries several lifting legs 8 to move synchronously. The lifting legs 8 lift the material bag on the first feeding rod 3111, so that the height of the material bag on the first feeding rod 3111 is the same as the height of the material bag on the second feeding rod 321.

[0044] Here, the material bag located on the first feeding rod 3111 is defined as the first material bag, and the material bags on the two sets of second feeding rods 321 located on both sides of the first feeding rod 3111 are the second material bag and the third material bag, respectively.

[0045] In the initial state, the first, second, and third material bags are on the same horizontal plane, and the head and tail ends of the first material bag are in contact with the second and third material bags respectively. After the lifting leg 8 lifts the first material bag, the second and third material bags are stationary. The first material bag is lifted between the second and third material bags until the first material bag is above the second and third material bags.

[0046] At the same time, the second and third material bags are driven by the second feeding rod 321, so that the second and third material bags move closer to each other along the support frame 33 until the head and tail ends of the first material bag abut against the second and third material bags respectively.

[0047] Subsequently, the piston rod of the drive cylinder retracts, causing the lifting support leg 8 to carry the first material bag and move closer to the first feeding rod 3111 until the first material bag, the second material bag, and the third material bag come into contact with each other again and are on the same plane, thus completing the shaping operation of the three material bags.

[0048] Correspondingly, the lifting assembly 312 also includes guide rods 3123, which are fixedly connected to the support frame 33. A guide hole is provided on the lifting plate 3122, and the guide rods 3123 slide in conjunction with the guide hole. Four guide rods 3123 are arranged in a rectangular array on the support frame 33 and fixedly connected to the lifting plate 3122. When the lifting plate 3122 carries the lifting leg 8 and moves along the support frame 33, the guiding action of the guide rods 3123 enables the lifting plate 3122 to slide stably along the support plate.

[0049] The implementation principle of a loading device for a material packaging cart according to an embodiment of this application is as follows: the main conveying mechanism 2 orderly delivers the material package to the shaping and conveying module 3, so that the first feeding rod 3111 and the two sets of second feeding rods 321 are respectively placed on the material package. Then, the lifting leg 8 lifts the material package on the first feeding rod 3111. The two sets of second feeding rods 321 located on both sides of the first feeding rod 3111 rotate in opposite directions along the support frame 33, so that the material packages on the two sets of second feeding rods 321 move closer to each other along the support frame 33 until the head and tail of the material package on the first feeding rod 3111 abut against the material packages on the two sets of second feeding rods 321. Only then can the lifting leg 8 carry the material package down along the support frame 33 to complete the shaping operation of the material package.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
