Description

Technical Field

[0001] This utility model belongs to the technical field of straw production equipment, specifically relating to a straw bale handling and conveying line. Background Technology

[0002] After the straw pellets are produced, they are usually filled directly on the production line using a quantitative packaging machine. During the packaging process, when the weight of the pellets reaches the preset value, the automatic quantitative packaging machine will stop filling and then perform subsequent operations such as sealing. After that, the packaging bags are transported and transferred.

[0003] Currently, roller conveyor belts are commonly used for transferring materials of moderate weight. Roller conveyor belt transportation can provide continuous and stable material transportation with high conveying stability and can handle materials of different weights.

[0004] However, since the packaging bags cannot be transported to the end of the same roller conveyor line, they usually need to be picked up and transferred to another conveyor line by a robotic arm. When the robotic arm picks them up, the packaging bags are laid flat on the conveyor line, and the robotic arm's claws cannot reach under the packaging bags to hold them. This means that the robotic arm can only pick up the packaging bags by gripping the sides. However, since the packaging bags contain straw particles, this requires a lot of gripping force and is prone to damaging the packaging bags. This leads to machine downtime for maintenance, which in turn reduces the production cycle and reduces production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a straw bale handling and conveying line to solve the problem of difficulty and inconvenience in transferring and transporting straw bales.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A straw bale handling and conveying line, comprising:

The output end of the lifting mechanism, which is disposed on the frame, is connected to the roller conveyor mechanism and is used to lift the roller conveyor mechanism. The roller conveyor mechanism has clearance notches on both sides of its top corresponding to the gripper fingers.

[0010] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0011] By installing a lifting device at the end of the roller conveyor belt, the entire bag transported from the roller conveyor belt can be lifted. At the same time, a clearance notch is opened on the roller conveyor mechanism at the top of the lifting device to cooperate with the claw fingers in the gripper assembly.

[0023] In one embodiment, the roller conveying mechanism includes two mounting plates and roller components rotatably connected between the two mounting plates. The clearance notches are spaced apart on the mounting plates and are located between two adjacent roller components.

[0024] In one embodiment, the bearing surfaces of a plurality of the roller components are at the same horizontal plane as the bearing surface of the roller conveyor belt.

[0041] Example

[0042] like Figure 1 As shown, the present invention provides a straw bale handling and conveying line, which includes: a roller conveyor belt 1, a gripper assembly 2, and a lifting device 3.

[0043] The roller conveyor belt 1 is used for long-distance transport of packaged straw pellets. The lifting device 3 is located at the end of the roller conveyor belt 1, so that the package on the roller conveyor belt 1 can be transferred straight to the lifting device 3. The gripper assembly 2 is located above the lifting device 3 at the end of the roller conveyor belt 1. The gripper assembly 2 is connected by a mechanical arm (not shown in the figure). The gripper assembly 2 includes several symmetrically arranged claw fingers 201.

[0044] The lifting device 3 includes a frame 301, a lifting mechanism 302, and a roller conveyor mechanism 303. The output end of the lifting mechanism 302, which is mounted on the frame 301, is connected to the roller conveyor mechanism 303. The roller conveyor mechanism 303 is mounted on the frame 301. The lifting mechanism 302 is used to lift the roller conveyor mechanism 303 and raise it above the roller conveyor belt 1. The roller conveyor mechanism 303 has clearance notches 4 on both sides of its top corresponding to the claws 201, so that the claws 201 can extend into the bottom of the material bag through the clearance notches 4.

[0045] By using the lifting device 3 located at the end of the roller conveyor belt 1, the entire bag transported from the roller conveyor belt 1 can be lifted. At the same time, a clearance notch 4 is provided on the roller conveyor mechanism 303 at the top of the lifting device 3 to cooperate with the claw fingers 201 in the gripper assembly 2. This allows the claw fingers 201 to extend from the clearance notch 4 to the bottom of the bag on the roller conveyor mechanism 303, making it easier to support the bag from below, clamp it more firmly, and make it more stable during transfer.

[0046] The gripper assembly 2 includes a top plate 202, two swing arm assemblies 203 and two first drive cylinders 204. The top of the top plate 202 has an interface for connecting with the robotic arm.

[0047] Two swing arm assemblies 203 are symmetrically arranged below the top plate 202. The middle part of the swing arm assembly 203 is rotatably connected to the top plate 202. Specifically, hanging plates 207 are provided on both sides of the bottom of the top plate 202. The middle part of the swing arm assembly 203 is rotatably connected to the hanging plates 207 through a pin. The claw finger 201 is installed at the bottom of the swing arm assembly 203. The claw finger 201 moves with the two swing arm assemblies 203. Two first drive cylinders 204 are arranged at the bottom of the top plate 202. The output ends of the two first drive cylinders 204 face to both sides and are connected to the top of the swing arm assembly 203 on both sides to drive the swing arm assembly 203 to open and close.

[0048] Specifically, the swing arm assembly 203 includes two swing rods 2031, with a mounting rod 2032 at the bottom of each swing rod 2031. Several claw fingers 201 are spaced apart on the mounting rod 2032. A hanging plate 207 is set at the bottom of the top plate 202 corresponding to the swing rods 2031. The middle parts of the two swing rods 2031 are rotatably connected to the hanging plate 207 via pins. The output end of the first drive cylinder 204 can be connected to the top of one of the swing rods 2031 in the swing arm assembly 203 to drive the overall movement of the swing arm assembly 203.

[0049] In this embodiment, the gripper assembly 2 further includes a pressure plate 205 and a second drive cylinder 206.

[0050] The pressure plate 205 is disposed between the two swing arm assemblies 203. The second drive cylinder 206 is installed at the bottom of the top plate 202. The output end of the second drive cylinder 206 is connected to the pressure plate 205 and is used to drive the pressure plate 205 to move up and down reciprocally. By driving the pressure plate 205 through the second drive cylinder 206, after the first drive cylinder 204 drives the claw 201 to grab the bottom of the material bag, it then adheres to the top of the material bag, ensuring the stability of the material bag during the handling process.

[0051] Specifically, the claw 201 includes a vertical rod 2011, which is fixed to the mounting rod 2032. The bottom of the vertical rod 2011 is provided with an inwardly bent horizontal rod 2012, which is mainly used to extend into the bottom of the material bag after reaching the clearance notch 4.

[0052] To reinforce the horizontal rod 2012 and vertical rod 2011 of the claw 201, a reinforcing rod 2013 is also included, with its two ends connected to the vertical rod 2011 and the horizontal rod 2012 respectively. The end of the reinforcing rod 2013 connected to the horizontal rod 2012 is not close to the inner end of the horizontal rod 2012. Since the inner end of the horizontal rod 2012 is used to contact the material bag, a certain distance needs to be left so that the horizontal rod 2012 can be inserted into the bottom of the material bag.

[0053] In this embodiment, the roller conveying mechanism 303 includes two mounting plates 3031 and roller components 3032 rotatably connected between the two mounting plates 3031. The mounting plates 3031 are correspondingly connected to both sides of the roller conveyor belt 1, and the roller components 3032 are continuously corresponding to the rollers in the roller conveyor belt 1, so that the material bag on the roller conveyor belt 1 can be directly transferred to the roller conveying mechanism 303 of the lifting device 3. The avoidance notches 4 are spaced apart on the mounting plates 3031, and the avoidance notches 4 are located between two adjacent roller components 3032, avoiding the roller components 3032, so as to ensure that the claw 201 does not interfere with the roller component 3032 after it extends into the avoidance notch 4.

[0054] Furthermore, the bearing surfaces of several of the roller components 3032 are at the same level as the bearing surface of the roller conveyor belt 1, so that the material bag conveyed from the roller conveyor belt 1 is smoothly transferred to the roller conveyor mechanism 303 without any height difference.

[0055] To facilitate the automated grabbing of material bags and the operation of the lifting device 3, a proximity switch 6 is provided on the top of the lifting device 3 near the baffle 5. The proximity switch 6 can determine that the material bag has reached the lifting device 3, and then control the lifting device 3 and the gripper assembly 2 to operate, while simultaneously controlling the roller conveyor belt 1 to stop to prevent material accumulation.

[0056] To ensure that the material bag undergoes a large displacement after reaching the lifting device 3 due to inertia, a baffle 5 is provided at the end of the lifting device 3 away from the roller conveyor belt 1. The baffle 5 can play a role in blocking and positioning.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
